Revision cases demonstrated a particularly high rate of traffic. Implementation of strategies, such as storage of instruments and components in the operating room and education of OR personnel, is required to reduce door openings in the OR.

Use of vancomycin in addition to cefazolin appeared to reduce the incidence of MRSA infections; however, the number needed to treat to prevent a single MRSA infection was very high.

To increase diversity in orthopaedic residency programs, an emphasis on recruiting ethnic and gender minority candidates needs to become a priority in the orthopaedic academic community.

CLINICAL RELEVANCE: Variability in patient preferences for outcome is an important, but perhaps underestimated, clinical parameter. Meaningful assessment of patient preferences when recommending treatment or creating clinical practice guidelines will lead to better shared decision making.

However, the recent standards are those of the physician who directly supervises the professional conduct of a resident in a given situation.

Near anatomical reduction can be achieved and maintained. While our findings need to be confirmed in studies with high rates of followup, patients with unstable LC pelvic injuries should be counseled concerning the possibility of some degree of persistent disability.

Further high-quality comparative studies are required to adequately compare drilling modalities, clearly define radiographic healing, and patient-oriented outcomes after nonoperative treatment.

Experimental studies suggest BP therapy protects the infarcted femoral head from deformity, but it lacks bone anabolic effect. Further basic and clinical research are required to determine the potential role of BPs as a medical treatment for LCPD.

The patient had undergone liver transplantation 6 years earlier. En bloc resection of the tumor and limb salvage was performed. At the 2-year followup the patient had no signs of local recurrence or metastatic spread; the patient had a Musculoskeletal Tumor Society (MSTS) score of 87. LITERATURE REVIEW: A literature review suggests the main predisposing factors to such malignancies are immunosuppression and its length of use. According to the literature, tumors apparently are rare in bone after liver transplantation, with no clearly documented cases. However, in the presence of such a finding, our study might be the first clearly documented case study of this kind of bone...

CASE DESCRIPTION: A 27-year-old military recruit began having left knee pain after 2 weeks of basic training, without any injury. Subsequently, right knee, right hip, and left hip pain developed sequentially within 2 weeks. The diagnosis of multifocal subchondral stress fracture was confirmed by plain radiographs and MR images. Nonoperative treatment of the subchondral stress fractures of both medial tibial condyles and the left uncollapsed femoral head resulted in resolution of symptoms. The collapsed right femoral head was treated with a fibular strut allograft to restore congruity and healed without further collaps...

Patients should be informed if there is a plan to introduce a new model of endoprosthesis in the hospital and offered the possibility to choose a conventional endoprosthesis instead. Although introducing potentially better endoprostheses is important, there is a need for managed introduction of new technology. LEVEL OF EVIDENCE: Level I, prognostic study.

Interobserver reliability for all three methods was low. New radiographic parameters to consistently identify congruency will be helpful for evaluating the preoperative indications for reconstructive osteotomy. CLINICAL RELEVANCE: Hip congruency has long been cited as a requirement for a reconstructive pelvic osteotomy, but based on the above findings, there is no clear agreement regarding what comprises a congruent joint. Thus, better criteria are needed to assess preoperative hip congruency to determine the role of congruency in patient outcomes after sur...

We did observe slight measurable amounts of oxidation in the inserts; however, it was far below levels that would be expected to compromise the strength of the polymer. CLINICAL RELEVANCE: Due to the stable oxidative and mechanical properties, EtO-sterilized tibial components appear to be an effective alternative to gamma-sterilized inserts, at least in short-term implantations.

Longer outcomes studies are required to see if reimbursements for complications differ between devices. LEVEL OF EVIDENCE: Level III, economic and decision analysis.

Lateral acetabular coverage changed during the growing years in all patients. Surgical correction beyond 44° of CE angle and -6° of ARA should be avoided to prevent pincer morphology later.

Shell deformation, soft tissue in the taper, or simulated taper damage seemed well tolerated even with very forceful impaction. Forceful and repetitive impaction is favorable for engagement of the taper and improving pullout strength.

Completed fractures may occur through the thickened bone in the absence of an appreciable transverse stress fracture line. Our observations suggest prophylactic reconstruction nail fixation may avoid fracture completion and may be associated with a shorter hospital LOS and less morbidity than treatment of completed fractures.

This evolving online environment of professional interaction is one of few precedents, but the application of risk management strategies that physicians use in daily practice carries over into the online community. This participation should foster ongoing dialogue as new guidelines emerge. This will allow today's orthopaedic surgeon to feel more comfortable with online professional networks and better understand how to make an informed decision regarding their proper use.

Our data suggest the high-flexion knee score differentiates among the knee status in the high-function range. Furthermore, the high-function knee score eliminates the ceiling effect of the currently used scoring tools, and thus may be useful when combined with other scoring systems.

CASE DESCRIPTION: A 13-year-old gymnast presented with a 3-week history of insidious onset of pain in the proximal clavicular area of his left shoulder. He had no pain at rest or at night. He recently had added a new maneuver to his routine. His radiographs were normal, but further study with CT scanning confirmed a stress lesion of his proximal clavicular physis. The lesion healed with time, and he returned to gymnastics with no symptoms. Approximately 5 months after the initial symptoms on the left side, he felt a pop and immediate pain in his right sternoclavicular joint area while doing a rou...

This migration pattern may be due to poor initial stability with a subsequent lack of osseointegration. Our results differ from radiographic findings and clinical durability of other similar cementless stem designs. LEVEL OF EVIDENCE: Level IV, therapeutic study.

The overall short- to medium-term revision rate was 2.2% and 5.4% for ceramic-on-ceramic and metal-on-metal, respectively.

Studies addressing cost-utility of nonoperative and operative management of low back pain encompass a broad spectrum of diagnoses and direct comparison of treatments based on cost-utility thresholds for comparative effectiveness is limited by diversity among disorders and methods to assess cost-utility. Future research will benefit from uniform methods and comparison of treatments in cohorts with well-defined pathology.

The addition of K(2)SO(4) appeared beneficial when using synthetic CaSO(4). Synthetic CaSO(4) may be effective when slow degradation and longer elution times are needed.

The highest ranked clinical criteria included the Ortolani/Barlow test, asymmetry in abduction of 20° or greater, breech presentation, leg-length discrepancy, and first-degree relative treated for DDH.

The patient developed urinary retention, bowel incontinence, and paresthesias in the saddle region on postoperative Day 3. She underwent emergent exploration and decompression of the thecal sac. The gel-like DuraSeal™ material was causing significant compression of the thecal sac. LITERATURE REVIEW: Multiple reports have documented that DuraSeal(™), used as an adjunct to dural repair, can swell leading to compression of the spinal cord and/or neural elements. Our case demonstrates the use of DuraSeal(™) both over a site of a dural repair and over a...

We believe through leadership and involvement in policy formulation and development, orthopaedic surgeons are best equipped to accurately and comprehensively inform the quality reporting process and its application to improve the delivery and outcomes of orthopaedic care.

To prevent chronic exertional compartment syndrome, it is necessary to address aspects other than the muscle fascia. LEVEL OF EVIDENCE: Level II, prognostic study.
