This approach offers the benefit of improved soft tissue coverage and the potential for a lower rate of wound-healing complications by avoiding incision placement over the subcutaneous border of the tibia. Although the fracture pattern dictates specific plate use, antomically designed anterolateral plates are useful for fixation of common fracture patterns. Additional exposures may be required to address other areas of the fracture, such as the medial malleolus, which cannot be accessed through this approach.

The patient presented with diffuse pain and swelling of the right shoulder for several years. Radiographs showed severe osteolytic lesions in the humeral head and neck, greater tuberosity, and a small osteolytic lesion in the glenoid neck area. Further examination with magnetic resonance imaging of the shoulder joint showed a large, lobulated soft tissue mass extending from the subdeltoid area to the chest wall invading the adjacent bony structures. The operative findings included a large, multilobulated, yellowish-brown mass extending from the subdeltoid area to the axillary pouch, subacromial space, ...

Bone metastasis can be seen in a relatively late phase of the disease, with metastasis to other organs. Although radiation therapy is effective in controlling pain from bone metastases in unresectable disease and those with extensive visceral metastases, aggressive local surgical control of a solitary bone metastasis may be an option for patients with limited distant disease. The diagnosis may be initially confused with clear cell meningioma and benign meningiomas. The management of bone metastasis is not well reported in the orthopedic literature.

The aggressive appearance on plain radiographs and MRI suggested a malignant bone tumor. This preliminary diagnosis was confirmed due to the presence of local lymph node spread on positron emission tomography/computed tomography. After a core needle biopsy revealed nondiagnostic tissue, rather than performing a wide resection based on a presumptive malignant diagnosis, we followed the standard diagnostic algorithm and performed an open biopsy with temporary internal stabilization. The tissue sample was adequate and revealed a diagnosis of epithelioid hemangioma. Based on this finding, we were able to proceed with surgical...

The patient presented with ankle pain with no previous history of gout. On examination, tenderness on the posterior aspect of his ankle and limitation of plantarflexion was noted. Laboratory values were normal, except for an elevated serum uric acid value. Radiographs of the right ankle showed the presence of a large os trigonum with osteosclerotic changes, whereas magnetic resonance imaging showed intraosseous tophus deposits in the os trigonum. Conservative therapy failed, and the patient was admitted for an endoscopic resection of the os trigonum.Intraosseous chalky crystals were detected during endoscopic resection of the os trigonum.

The RIA was used for canal preparation, and solid reamings were collected and submitted for analysis by a single pathologist. The volume of each specimen was recorded, and representative samples were examined histologically to determine their percent tumor content. These data were then used to estimate the volume of tumor retrieved by the RIA in each case. The mean volume of reamings collected by the RIA was 75.0...

In 2006, trace quantities of human β-defensin 3 (hBD-3) were found in human bone tissue and bone cells. Human β-defensin 3 is a 45-amino-acid peptide that is considered the most promising class of defensin antimicrobial peptides and may help in the prevention and treatment of implantation-associated infections. Studies of the effectiveness of hBD-3 against Staphylococcus aureus showed that hBD-3 was more potent at low concentrations than other antibiotics.

Twenty-five consecutive patients at a single institution were treated between 2006 and 2010 for a variety of diagnoses including tumors, infections, and trauma. Treatment variables, including operating time, estimated blood loss, number of levels treated, and complications, were collected, as were visual analog scale (VAS) scores for pain.Surgical times (mean, 188.5 minutes) and blood loss (mean, 423 mL) reflect a significant improvement over standard open corpectomy procedures.

The steel bar entered the pelvic cavity from the left buttock through the sciatic notch and was bent at the middle of the pelvic cavity between the bladder and rectum. At the right hip joint, the rod penetrated the posteromedial aspect of the femoral head, was bent again, and extended straight along the medial border of the femur without damaging the femoral neurovascular bundle. At the middle one-third level, the bar spanned in a posterolateral direction and then down toward the lateral aspect at the level of the mid-calf.

This abnormal relationship leads to altered biomechanics of the hip joint, as predicted by measurement of kinematic parameters such as increased load over reduced acetabular weight-bearing area, leading to increased joint contact stresses, which subsequently results in secondary osteoarthrosis, pain, and disability. To prevent these sequelae, particularly in children and younger adults, various osteotomies have been performed with varying degrees of success.

The condition should be considered in the initial differential diagnosis of an adolescent presenting with fever, difficulty ambulating, and hip pain. This is a retrospective review of 8 cases of primary pelvic pyomyositis in patients aged 18 years or younger who were treated at the Children's Medical Center in Augusta, Georgia. The site of infection was the obturator internus in the majority of the cases (5). The site was the gluteus, iliopsoas, and iliacus in 1 case each.

The total rate of bilateral TKA has doubled over the past 2 decades, and the rate in women has tripled over that same time period. In patients with bilateral knee arthritis, a decision must be made whether to operate at 2 different settings (staged), a single setting with 1 surgeon (sequential simultaneous), or a single setting with 2 surgeons (2-team simultaneous). The purpose of this study was to examine the perioperative morbidity and mortality of 2-team simultaneous bilateral TKA.

Risk is defined as the product of the probability of an event occurring and its consequence. To define consequence, 2 related scales of impact (1 systemic and 1 local) are suggested. The probability of a complication is derived from the incidence as found in the published literature and expressed as a decimal of 1. The cumulative risk is expressed as the sum of the risks of all individual complications. The overall impact of specific comorbidities has been calculated when their influence on the incidence of a particular complication is known.Of the 3 operations, TKA has ...

Because these secondary changes cannot heal spontaneously after skeletal maturation if left untreated, the patients frequently possess pathology not limited to the knee joint and extending to the whole lower extremity, such as malalignment or leg-length discrepancy, that can develop into osteoarthritis of the knee. However, to our knowledge, few surgeons advocate the significance of correcting the malalignment in treating adult patients.We treated a 34-year-old woman with permanent dislocation of the ...

The first patient was a 74-year-old man who presented with weakness in the right foot and a vesicular rash. The pattern of disease supported the clinical diagnosis of shingles affecting the L5 motor and sensory division. No investigation was required, and the patient was treated with a foot drop splint. The second patient was a 71-year-old man who presented with right leg and foot weakness and a vesicular rash affecting his right buttock and posterior right thigh. Lumbar magnetic resonance excluded a stenotic lesion; electrophysiological studies supported the diagnosis of a lower motor neuron lesion. The patie...

Customized bone tamps can be fabricated intraoperatively using commonly available instruments and supplies consisting of Steinmann pins and T-handled chucks. The technique combines the use of bone tamps through carefully created metaphyseal windows, fluoroscopic guidance, packing with cancellous bone, and adequate fixation. This treatment methodology can allow for a minimally invasive or soft tissue preserving approach for the treatment of some intra-articular fractures while achieving anatomic reduction of the joint surface.

A great effort is made to preserve the native meniscus and restore the circumferential fibers for hoop stress resistance. It has been well demonstrated in the literature that failure to repair this will lead to increased contact pressures in the medial compartment and early degenerative changes in the articular cartilage. Our technique is one that allows the meniscus to resume its important role of knee stability. A thorough understanding of meniscal root anatomy, as well as repair techniques, is important for the cruciate ligament surgeon.

Often, a significant period of time elapses after injury before the patient is assessed by the orthopedic surgeon; therefore, the initial MRI may be considered outdated because of a new injury or a change in symptoms or because the orthopedist may prefer a new study, a stronger magnet, or a special imaging protocol. However, the decision to repeat a knee MRI is presently an arbitrary one because no clinical guidelines exist to justify this practice.All repeat knee MRIs performed at our academic institution in the past 9 years were retrospectively examined.

A 16-year-old boy sustained a varus force and twisting injury to his knee, resulting in radiographic evidence of multiple avulsion fractures of the knee, including a fibular epiphyseal avulsion fracture and medial and lateral Segond fractures. Usually, the avulsion fractures serve as markers for significant ligamentous injuries in adult patients, but our patient had minimal injury to the PCL, ACL, and posterolateral corner. Further physical examination and imaging studies revealed an anterior horn root avulsion, meniscocapsular separation, and anterior cortical rim fracture. A combination of imaging modalities helped us further characterize the injury pattern to devise the optimal surgical plan, e...

There were no associated fractures with his injury. Our patient underwent staged irrigation and debridement of his shoulder with delayed tendoligamentous reconstruction of the skeletonized proximal humerus. After reconstruction, he was immobilized for 3 weeks and then began a progressive shoulder rehabilitation protocol. He healed with no evidence of infection, residual instability, or avascular necrosis at his 4-month follow-up examination. At that point, he had regained functional use of his shoulder for activities of daily living and had no pain. His range of active motion was limited to 90° of flexio...

A 14-year-old boy was diagnosed with congenital epidermolysis bullosa. He was treated in our hospital several times, but the pathogenetic condition worsened. On examination, both hands were clenched fists and had scar formation. Skin fusion was observed between the 5 fingers. Nails were absent and the thumb was in the fist. His fingers were short, and active and passive flexion and extension could not be performed. The right hand was treated first. After the adhesions were separated, we found that the 5 fingers were connected by dermis. After the dermis was separated and the hand was fixed in the extension position, there were sma...

Physical examination suggested physiologic hyperlaxity and anterior instability. Magnetic resonance arthrography demonstrated an anomalous intracapsular origin of the long head of the biceps tendon (LHBT), with normal-appearing LHBT in the intertubercular groove. Diagnostic arthroscopy confirmed the absence of the LHBT attachment on the superior labrum. Instead, the LHBT originated from the capsule of the shoulder joint. Diagnostic arthroscopy also revealed glenoid avulsion of the glenohumeral ligaments (GAGL) lesion as a tear in the anterior-inferior capsule near its insertion on the glenoid and labrum. An...

Magnetic resonance imaging findings showed diskal cysts in the epidural space of the lumbar spine. Surgical resection was performed, and apparent connections between the corresponding disk and cysts were found. Histopathologic examinations of the cyst wall demonstrated cartilaginous tissue including nucleus pulposus and annulus fibrosis. These patient's symptoms improved remarkably postoperatively, and there was no recurrence of diskal cyst.The hypothesis supported by many authors is hemorrhage from the epidural venous plexus. Diskal cysts arise first from an underlying intervertebral disk injury that causes an annulus fibrosis fissure in the posterior intervertebral disk. Hemorrhage from the epidur...

The last acute gout flare in his left wrist was approximately 3 years prior. For 2 years he had refused adequate nutrition, such as a low-purine diet, and had refused to take any preventive medication. Blood urate level was elevated to 8.7 mg/dL (normal range, 3.4-7.0 mg/dL). In time, the tophi led to a massive limitation of motion and use of especially the left wrist and thumb. Under the condition that the patient changed his diet and took the medication for his underlying disease, we surgically removed the almost skin-perforating tophi. Surgical debulking significantly improved joint function and cosmetic appearance.The best treatment for gouty tophi is prevention by ensuring adequate nutritio...

Glenoid component explantation and bone grafting of defects have become common methods of recreating bone stock in hopes of preventing later fractures, maintaining joint kinematics, and allowing for later glenoid reimplantation if necessary. Although this has been traditionally accomplished via open techniques, this article describes an arthroscopic-assisted method of glenoid explantation and bone grafting for cases of aseptic glenoid loosening with contained bone defects.

An initial immunoassay reports qualitative results based on established cut-off concentrations. As a screening test, the initial immunoassay is less sensitive and therefore must be interpreted in the context of confounding variables such as the testing method, the substance being screened, and patient-specific characteristics.

Avascular necrosis of the femoral head was clinically symptomatic in all of the children, and they had advanced radiographic collapse of the femoral head. However, the head of the femur was not at risk in any patient based on clinical and radiographic findings. Patients received supportive t...

The purpose of this study was to consider prices and outcomes in an integrated model and thereby determine if teaching hospitals are cost-effective for the care of hip fractures. We analyzed the claims data of a sample of 18,908 Medicare patients who were admitted to one of 190 acute care hospitals for surgical treatment of a hip fracture. For each hospital, we assessed the relationship between the total per capita Medicare payments over a 6-month period following admission and the 30-day and 6-month mortality. The data were analyzed as a function of hospital type: teaching vs...

Twenty-one patients (25 limbs) were identified who underwent femoral lengthening. The limbs were lengthened a mean of 6.1 cm, and mean follow-up was 1.5 years. The immediate postoperative deformity in the sagittal plane was 8.3°; this deformity did not progress during lengthening (P<.05). Mean displacement in the sagittal plane was 3.1 mm.Angular deformities, although typically small, can occur in the sagittal plane and may be accompanied by displacement. These deformities are usually present immediately postoperatively and typically do not worsen significantly wi...

Diagnosis is usually based on clinical findings and serum C-reactive protein (CRP) levels. However, diagnosis can be challenging when the clinical findings are normal but the CRP level is high. From March 2007 to January 2008, fluorodeoxy-glucose positron emission tomography (FDG-PET) was used to detect infection around antibiotic-loaded cement spacers in 13 patients (mean age, 60 years). Although patients' clinical conditions were deemed suitable for reimplantation, their serum CRP levels were persistently elevated (mean, 54 mg...

We used readily available operating room equipment to create a distal femoral vent hole without interfering with standard intramedullary instrumentation and with minimal increase in surgical time. This technique can be used for the prophylactic intramedullary stabilization of impending pathologic femur fractures from metabolic bone disease, metastatic cancer, and bisphosphonate use.
