Both cases had three levels of deformity that were addressed with tibial osteotomy, ankle fusion, and total knee replacement. Initial presentation, problem lists, surgical treatment, and subsequent results are reviewed. Literature Review  Treatment of a post-traumatic three-level deformity has never specifically been addressed in the literature, although the principles of treatment are the same as for less complex deformities. Purposes and Clinical Relevance  These two cases present a treatment approach for complex, multiapical deformity of the tibia. The same...

These tests help differentiate between cervical radiculopathies, brachial plexopathies, and peripheral nerve injuries. They also help to identify or rule out other underlying neurological diseases and disorders. In this case report, a 22-year-old male swimmer presented with left finger extensor weakness following pull-up exercises. Left wrist extension remained intact. Electrodiagnostic testing revealed a severe but incomplete posterior interosseous neuropathy. Magnetic resonance imaging confirmed inflammation of the nerve in the forearm. Posterior interosseous neuropathy is an uncommon but well-studied condition. Typically, this condition presents with weakness in finger and thumb extensi...

PRP has been shown to be a safe treatment. A number of questions regarding PRP remain unanswered, including the optimal concentration of platelets, what cell types should be present, the ideal frequency of application, or the optimal rehabilitation regimen for tissue repair and return to full function.

A 78-year-old Caucasian male with MM, previously treated with chemotherapy, who was off chemotherapy for 2 years due to bone marrow suppression, presented with a solitary recurrence at the left anterior superior iliac spine of the left iliac wing as diagnosed by PET-CT scan. This lesion was treated with a minimally invasive osteoplasty and intra-operative brachytherapy with to a dose of 8 Gy delivered to the surgical cavity only, followed by injection of the bone cement into the cavity.

Our study group showed good to excellent results as well as improvement in range of motion at minimum 2-year follow-up. The results presented in this study are comparable to previous outcomes achieved with conventional length humeral components, and suggest that mini-stem humeral components are an effective option for total shoulder arthroplasty.

He presented with complaints of pain and swelling in the operated extremity several days after rotator cuff surgery and underwent ultrasound evaluation that confirmed thrombosis of the axillary vein with extension into the brachial and basilic veins, down to the level of the elbow. He was treated with Coumadin, as well as enoxaparin (Lovenox) at therapeutic dosages until INR levels were in the therapeutic range. Follow-up ultrasound at 6 months demonstrated successful recanalization of the affected vessels and no further complications were noted.

While autograft reconstruction remains the gold standard, allograft tissues have become a controversial option for ACL reconstruction. No data currently exist regarding recent trends in graft choices, and no consensus exists over which graft type is most appropriate for which patient. In this article, we examine trends in ACL graft choice at our institution, and review the pertinent information a surgeon must consider when making this decision. We reviewed operating room records from 2002 to 2008 to determine trends in graft choice for primary single bundle ACL reconstruction. Total number of procedures performed, graft choices, and patient ages w...

Typically, knees with deformity, rheumatoid arthritis, previous patellectomy or high tibial osteotomy, and posttraumatic arthritis carry higher risks of post-operative instability and are indications for more constrained TKA designs. Instability following TKA usually requires revision surgery which must address the cause of the instability for success.

However, there is poor reliability among observers in measuring the size of the enthesophyte. This study suggests that the enthesophyte–humeral distance may be more reliable than the enthesophyte length when measuring the size of the enthesophyte.

Genetic, environmental, and occupational influences may play a role. These spondylotic changes may result in direct compressive and ischemic dysfunction of the spinal cord known as cervical spondylotic myelopathy (CSM). Both static and dynamic factors contribute to the pathogenesis. CSM may present as subclinical stenosis or may follow a more pernicious and progressive course. Most reports of the natural history of CSM involve periods of quiescent disease with intermittent episodes of neurologic decline. If conservative treatment is chosen for mild CSM, close clinical and radiographic follow-up should be undertaken in addition to precautions for trauma-related neurologi...

Seventy-two patients with intact ligaments and loss of only medial articular cartilage received the Preservation prosthesis. Data were obtained using WOMAC, Knee Society score (KSS), and standard radiographs. WOMAC scores improved by 24 points and KSS improved by 33 points at 2-year follow-up.

Two senior surgeons performed all the surgeries. During that period, patients in group A (129 patients) all donated one unit of autologous blood and patients in group B (92 patients) did not donate. Within both groups, patients were further divided by preoperative hemoglobin level as either anemic or non-anemic. A hemoglobin of 12.5 g/dL was used as the cutoff.

Although the etiology is unclear, it is associated with progressive and asymmetric degeneration of the disc, facet joints, and other structural spinal elements typically leading to neural element compression. Clinical presentation varies and is frequently associated with axial back pain and neurogenic claudication. Indications for treatment include pain, neurogenic symptoms, and progressive cosmetic deformity. Non-operative treatment includes physical conditioning and exercise, pharmacological agents for pain control, and use of orthotics and invasive modalities like epidural and facet injections.

The modifications in this design included a deeper patellar sulcus aimed at reducing contact stresses, improving patellar tracking, and achieving greater maximum flexion. A consecutive group of 137 patients (171 knees) who underwent TKAs using the Optetrak PS knee prosthesis between October 1997 and March 2004 were followed for an average of 6.8 years (range 4.0–11.5 years). Preoperative range of motion (ROM) and Knee Society scores were obtained and compared to that of the patients’ most recent follow-up.

Less commonly, labral pathology may occur in an atypical direct anterior location adjacent to the iliopsoas tendon in the absence of bony abnormalities. We hypothesize that this pattern of injury is related to compression or traction on the anterior capsulo-labral complex by the iliopsoas tendon where it crosses the acetabular rim. In a retrospective review of prospectively collected data, we identified 25 patients that underwent isolated, primary, unilateral iliopsoas release and presented for at least 1 year follow-up (mean 21 months). Pre-operative demographics, clinical presentation, intra-operative findings, and outcome questionnaires were an...

The goal of this study was to assess the radiographic, functional, and clinical results of patients undergoing an anatomic lateral ankle ligament reconstruction using an anterior tibial tendon allograft. Eleven patients (12 feet; mean age, 48.9 ± 11.4 years) undergoing lateral ankle ligament reconstruction were followed at a mean of 3.5 ± 1.7 years after surgery (range, 1.2 to 5.0 years). Indications for surgery were previous failed repair (i.e., Broström; one case), hyperlaxity (seven cases), and high-demand patients (four cases).

The Society’s mission is to share knowledge and strategies, improve patient care, and foster clinical, educational, and scientific collaboration. As the Society’s agendas developed, the members recognized that many of their aims intersected with those of hospital leadership. Thus, CEOs from member centers were invited to join their physician colleagues at the 2010 meeting in Bologna, Italy in order to explore solutions to administrative challenges related to patient care, volume growth, and costs.

Following Institutional Review Board approval, a prospective study of 20 patients per group ages 70 and above undergoing unilateral THA or TKA was initiated. Both groups received a combined spinal–epidural, postoperative patient-controlled epidural anesthesia, and postoperative oral opioids. Patient interviews occurred five times: once preoperatively and two times each on postoperative days 1 and 2. Only two patients were assessed as delirious according to the CAM method (one in each group; 5%). Patient assessment by other clinicians indicated that five additional patients experienced...

Locking plates and screw were introduced to improve fixation of fragility fractures and have been in use for a decade. This review was conducted to compile evidence that locking plates and screws improve fixation of fragility fractures. A search of PubMed was performed to identify biomechanical studies as well as clinical series of fragility fractures treated with locking plates. Biomechanics papers had to use models of osteoporotic bone and had to directly compare locking plates with traditional plates. Clinical studies included case series in which locking plates were applied to elderly patients with fractures of the proximal humerus and peripr...

The study objective was to determine the radiographic findings that correlate with and are predictive of hip pain in femoroacetabular impingement (FAI). One hundred prospective patients with unilateral FAI symptoms based on clinical and radiographic findings were included in this study. All patients filled out a WOMAC pain questionnaire. Two independent-blinded surgeons assessed antero-posterior and lateral radiographs for 33 radiographic parameters of FAI. Correlations between pain scores and radiographic findings were calculated. A matched radiographic analysis was performed comparing symptomatic versus asymptomatic hips. R...

Although the etiology of the syndrome is unclear, it is reported in various clinical situations, including postoperatively, postinfectious, posttraumatic, and postvaccination. The identification of the syndrome in the postoperative patient remains a challenge as symptoms may easily be attributed to sequelae of surgical positioning, postoperative recovery, or postanesthetic block pain.

Many patients who have undergone previous percutaneous coronary intervention (PCI) with stenting are on dual antiplatelet therapy in order to minimize the risk of stent thrombosis. The optimal management of these patients in the perioperative setting remains unclear. We aim to provide information about the management of patients who have undergone a PCI with stents who are subsequently indicated for an orthopedic procedure. We will review the concerns from a cardiologist’s and orthopedic surgeon’s perspective in regards to the management of these patients in the perioperative setting.

The aim of this retrospective cohort analysis was to determine the prevalence of a new accessory muscle located at the level of the knee detected with magnetic resonance imaging (MRI). The accessory muscle is designated an accessory plantaris muscle in this study due to its intimate origin with the normal plantaris muscle. Retrospective review of 1,000 consecutive MRI exams of the knee performed on patients presenting with acute or chronic knee symptoms revealed an accessory plantaris muscle in 63 of the 1,000 patients (6.3%)—38 males (7.5%) and 25 females (5.1%).

Diagnosis was made by the use of high-resolution, time-resolved contrast-enhanced 3D magnetic resonance angiography, also referred to as “TRICKS” (time-resolved imaging of contrast kinetics). This technique provided high spatial resolution for the arterial anatomy as well as temporal resolution which allowed better delineation of the hemodynamic characteristics of the pseudoaneurysm.

Our postoperative OSA patients are all intensively monitored in the PACU and can provide such data. Thus, we reviewed patient records to determine incidence and risk factors for postoperative hypoxemia in OSA patients and subsequent association with postoperative complications. Five hundred twenty-seven charts of patients with OSA based on preoperative ICD-9 codes were reviewed for outcomes including episodes of hypoxemia and hypercarbia. Univariate analysis, logistic regression, and propensity analysis were performed to determine independent risk factors for hypoxemia and association with adverse outcomes.

The purpose of this study was to evaluate the effect of initiating physical therapy (PT) on post operative day 1 (POD1) compared to initiating PT on day of surgery (DOS), on length of stay and in-hospital rehabilitation functional outcomes in total hip arthroplasty patients. This change in PT guidelines was part of the implementation of a new multidisciplinary clinical pathway, adopted by the institution in 2007. A retrospective descriptive study of 408 subjects undergoing unilateral THA compared two groups (204 in each group): those who initiated PT on POD1 and those who initiated PT on DOS.

We sought to determine if a multimodal pathway focusing on pre-op discharge planning and pre-emptive pain and nausea management lead to reduced length of stay, better pain management, and more rapid functional gains without an increase in post-op complications. A multimodal pathway incorporating pre-op discharge planning and pre-emptive pain and nausea management was initiated in August of 2007. Physical therapy began the day of surgery. Two hundred eleven patients treated over a 3-month period with the new pathway were compared to 192 patients treated in the last 3 months of an older pathway. Length of stay, VAS scores for pain, and the incidence of nausea we...

Patterson, who had first joined the staff of The Hospital for the Ruptured and Crippled in 1936 as a Visiting Surgeon, was able to accomplish this very challenging task mainly through his close relationship with Preston Wade, MD (1901–1982), a general surgeon who had served with Patterson as Co-Chief of the combined New York Hospital-HSS Fracture service.

It has been speculated to be the result of greater soft tissue dissection required for this procedure. HO most commonly develops in males and patients with bilateral disease. To better understand if this problem does occur in RHA, groups of patients with RHA on one side and conventional THA on the other were evaluated. We retrospectively identified 45 patients that had RHA on one side and conventional cemented THA on the other. Follow-up has been up to 25 years. HO was graded at every clinical visit using the Brooker Classification. In the RHA group, there were 32 hips without evidence of HO, ten...

A multivariate analysis using a matched-cohort design was performed to assess any potential risk factors that may predispose to such fractures. Six of 2,220 hips (0.3%) suffered a periprosthetic femur fracture within the first year after surgery; five of six were Vancouver Type B2. The average time to fracture was 9 weeks. This group of patients had a significantly higher canal–flare index and lower canal–calcar ratio. This complication may be preventable by having a better appreciation of the fit between the implant and the bone during pre-operative planning, with the goal of avoiding a proximal–distal mismatch...

Allogeneic transfusion is the standard treatment for perioperative blood loss resulting in low postoperative hemoglobin, but it has a number of well-recognized risks, complications, and costs. Alternatives to allogeneic blood transfusion include preoperative autologous donation and intraoperative salvage with postoperative autotransfusion. Orthopedic surgeons are often unaware of the different pre- and intraoperative possibilities of reducing blood loss and leave the management of coagulation and use of blood products completely to the anesthesiologists. The goal of this review is to compare alternatives to allogeneic blood transfusion from an orthopedic and anesthesia point of view focusi...

Previous reports indicate that it is desirable to reimplant the glenoid component during revision shoulder arthroplasty. The purpose of our study was to retrospectively evaluate the satisfaction of patients undergoing glenoid revision (reimplantation or resection) following total shoulder replacement specifically for symptomatic glenoid loosening. Twenty-eight shoulders that developed symptomatic glenoid loosening following primary total shoulder arthroplasty were included in the study. Patients were retrospectively evaluated at a minimum of 2 years postoperatively. Patients either underwent resection followed by reimplantation of the glenoid component (13) or ...

Disruption of both collateral ligaments as a young adult and the subsequent development of traumatic arthritis required repeated surgical and extensive conservative treatment before a prosthesis was implanted. Examination disclosed marked instability of the lateral collateral ligament (LCL) and loosening of the tibial and the femoral components. Review of the MRI obtained prior to the total knee replacement revealed discontinuity of the LCL with intense scarring of the posterolateral ligament complex. Definitive management of this twofold problem was not helped by literature review, which failed to reveal a gold standard or a broad consensus ...

Electrodiagnostic testing revealed a musculocutaneous neuropathy with significant axonal injury. Symptoms of musculocutaneous neuropathy may be similar to cervical spinal nerve root impingement or brachial plexus lesions. Therefore, magnetic resonance imaging and electrodiagnostic studies may be useful in differentiating between these conditions. Once the diagnosis of musculocutaneous neuropathy has been made, treatments include relative rest, nonsteroidal anti-inflammatory drugs, splinting, physical therapy, and surgical decompression in cases that do not respond to conservative management.

When only intravenous on-demand hematological treatment is available, frequent evaluations are necessary for the early diagnosis and treatment of episodes of intra-articular bleeding. The natural history of the disease in patients with poorly controlled intra-articular bleeding is the development of chronic synovitis and, later, multi-articular hemophilic arthropathy. Once arthropathy develops, the functional prognosis is poor. Treatment of these patients should be conducted through a comprehensive program by a multidisciplinary hemophilia unit. Although continuous prophylaxis can ...

Exploration of the nerve was performed. The radial nerve was found to be stretched over the ends of the fracture. Open reduction and external fixation of the fracture with mobilization of the nerve from the fracture site lead to complete return of radial nerve function occurring by 3 months. We recommend exploration of cases of late-onset radial nerve palsy in contrast to primary or secondary radial nerve palsy, which can be treated conservatively. Our experience suggests that the cause of the palsy is a continuous ongoing pathology and not a single time event as in primary or secondary cases. Radial nerve palsies associated with ...

Diagnosis of the lumbar facet joint cyst is made through cross-sectional imaging of the spine, either by computerized tomography (CT) scan, myelography, or most commonly magnetic resonance imaging. Conservative treatment by facet joint injection can be performed under fluoroscopic or CT guidance, although only CT guidance provides direct visualization of the cyst confirming accurate needle placement. This case report illustrates the use of percutaneous CT-guided facet joint cyst treatment as a temporizing measure or alternative to surgical treatment in the proper clinical scenario.

There is no uniform accepted treatment protocol for these tumors. Curettage, although an accepted method of treatment, carries a high local recurrence rate. Adjuvant therapies including high-speed burr debridement, cryotherapy, and phenol treatment have been advocated to reduce local recurrence. We have used these adjuvants to determine if improved cure rate with improved outcomes could be attained with regard to local tumor control and functional outcome. Twenty-eight cases of proven giant cell tumors of the distal femur and proximal tibia were included in this prospective case series. The lesions were at the upper tibia in 14 cases and the lower femur in 14 patients. The pat...

To date, only anterior iliac crest regeneration has been reported in orthopedic trauma patients. A 70-year-old man with a history of two prior instrumented lumbar fusion operations developed thoracolumbar kyphosis junctional to the lumbosacral fusion mass. His first operation was an instrumented posterolateral lumbar fusion L1 to L5, where bone graft was harvested from the right iliac crest using the intracortical harvesting technique. The second procedure was performed 18 months later and consisted of an extension of the fusion to the sacrum due to L5–S1 level derived symptoms. The bone graf...

Clinically relevant respiratory failure is rare and is therefore difficult to study. To facilitate future investigations on this subject, we evaluated the utility of the elastin breakdown product desmosine as a potential marker of lung injury during TKA surgery. The goals of this study were to answer (1) if desmosine levels would increase in response to the perioperative insults in patients undergoing TKA and (2) if this increase would differ among unilateral and bilateral TKA procedures. Twenty consecutive patients (ten unilateral and ten bilateral TKAs) were enrolled. Urine samples were collected before surgery and at 1 and 3 days po...

Correct positioning of the femoral alignment wire with respect to the femoral neck is the key to avoiding complications. Although the surgeon must align the wire in two planes, we can only control one plane at a time without changing position or relying on the indications of an assistant. Independent placement of two parallel alignment wires, one for varus-valgus orientation and another for version orientation, will help to determine two planes, the valgus sagittal plane and the version coronal plane, at the intersection of which both the optimum point of entry into the femoral head and the orientation line of the femoral alignment wire can be ...

The clinical presentation initially appeared consistent with an ulnar nerve entrapment at the elbow. The true diagnosis of an ulnar sensorimotor nerve lesion occurring within the canal of Guyon was made electrophysiologically. Magnetic resonance imaging demonstrated compression of the nerve within the canal by a ganglionic cyst, which was confirmed by surgical intervention. Ulnar nerve entrapment at the wrist is uncommon and difficult to diagnose; therefore, it is important to understand the nerve’s anatomical course and distribution to allow for accurate diagnosis by clinical and electrodiagnostic evaluations. Electrodiagnosis is an important tool in identifying ulnar nerve lesio...

Only 5 years previously, its name was changed from the Hospital for the Ruptured and Crippled (R & C). In 1934, Dr. Philip D. Wilson (1886–1969) had been recruited to fill the office of the fifth Surgeon-in-Chief with a key charge to restore the hospital as the leading orthopedic institution in our country, a role it originally held for over half a century since its founding in 1863. Wilson believed that a close affiliation with a university center having a medical school and hospital, while maintaining independence, was vital to achieve this objective. In 1948, negotiations between representatives of the Bo...

The rationale for the use of the rotational acetabular osteotomy (RAO) is that it increases the weight-bearing area by shifting the osteotomized acetabulum to cover the femoral head. This can improve joint function as well as achieve relief of pain. However, it is unclear if this osteotomy can improve a compromised hip when performed for the treatment of residual deformity and acetabular dysplasia after surgery for developmental dysplasia of the hip. We aimed to report the clinical outcome as assessed by need for total hip arthroplasty (THA) and by the Merle d’Aubigné and Postel scores. In addition, we tried to assess the radiographic outcomes as ...

Using MEDLINE, Cochrane, Current Controlled Trials, UK National Research Register, ScienceDirect, CINAHL, and EMBASE, a review of randomized (level I) and quasi-randomized (level II) controlled trials was performed using an insole as the intervention and stress fracture incidence as the primary outcome measure. Five trials were included, and a random effects model was used to generate a summary estimate and an overall odds ratio. One study found a significant reduction in overall stress fracture incidence using a semirigid insole, while four studies found no overall reduction in military personnel. However, when the data...

The purpose of this study was to evaluate whether or not preoperative deformities predispose to intraoperative malposition of TKA components. A retrospective radiographic analysis of 53 primary TKA cases was performed. Preoperative AP hip to ankle and lateral knee radiographs were compared with postoperative views to evaluate component positioning. The following angles were measured: the hip–knee–ankle (HKA) angle expressing the mechanical axis of the leg, the mechanical lateral distal femur angle (mLDFA), the medial proximal tibia angle (MPTA), the posterior distal femur angle (PDFA), and the posterior proximal tibia angle (PPTA).

A scarcity of molecular targets in bone has thwarted the development of drugs to combat these conditions. Nuclear factor of activated T-cells (NFAT) is a master regulator of osteoclastogenesis and is induced by RANKL. The immunosuppressive drugs, Cyclosporin A and Tacrolimus, inhibit osteoclast formation by targeting the NFAT/calcineurin pathway. These NFAT inhibitors should be considered in the treatment of osteoclastic hyper-resorptive syndromes. Content Type Journal ArticleCategory Review ArticleDOI 10.1007/s11420-009-9115-xAuthors Mark S.

The cause and natural history of RDO are unclear, but total hip arthroplasty has been utilized as a treatment modality due to the severity of the symptoms. We reviewed retrospectively the records of total hip arthroplasties performed between 1990 and 2003 and identified ten hips in eight patients who fit the profile of the diagnosis of RDO. The mean age at time of surgery was 70. Nine hips were treated with total hip arthroplasty with a hybrid configuration; one hip was treated with a non-cemented total hip arthroplasty.

The peak incidence is in the fourth decade of life, and overall, there is a male preponderance. The condition accounts for up to 12% of total hip arthroplasties performed in developed countries. The etiology can be traumatic or non-traumatic, with 90% of atraumatic cases attributed to corticosteroid therapy or excess alcohol consumption. Osteonecrosis of the femoral head reflects the final common pathway of a range of insults to the blood supply and ultimately results in femoral head collapse, acetabular involvement, and secondary osteoarthritis. Currently, conservative treatment options, which aim to correct pathophysiologic features allowing revascul...

The effect of the intermittent administration of PTH (1-34) is an uncoupling of bone turnover with an increase in bone mass and density and decrease in risk of vertebral and nonvertebral fractures. While PTH (1-34) has been used clinically to increase bone mass and reduce fracture risk in postmenopausal women with osteoporosis, there is increasing evidence that PTH (1-34) may promote fracture healing. Animal studies have demonstrated accelerated callus formation with enhanced remodeling and biomechanical properties of the healing fracture. Given these effects, PTH (1-34) will likely be used clinically to enhanc...

In this case report, an individual presented with right upper extremity radicular symptoms consistent with a clinical diagnosis of cervical radiculopathy. EMG studies revealed that the lesion could be more specifically isolated to the T1 nerve root and, furthermore, provided evidence that the abductor pollicis brevis receives predominantly T1 innervation.
