Osteochondral defects of the femoral head are rare and principles of treatment include anatomic reduction, rigid fixation, enhancement of blood supply, and restoration of articular congruity. In this report, we present a case where the defect of the femoral head was treated with surgical dislocation of hip anteriorly and mosaicplasty. At 3-year follow-up, the patient was symptom free with near complete incorporation of the graft radiographically. Our observations in this case suggest that mosaicplasty with an open approach is an alternative treatment in the osteochondral defects of the femoral head...

Hibernoma is an uncommon, benign tumor of brown fat origin. The distribution of this tumor originally was described as following the location of persistent brown fat within the subcutaneous tissue of the thorax (especially the periscapular and interscapular regions), neck, axilla, shoulder, and retroperitoneum. Recently, hibernoma was described as being most common in the thigh.

Wire breakage and migration is a known complication of using a wire tension band construct to treat displaced patella fractures. We report a case of a broken K-wire that migrated from the patella completely into the proximal tibia without complication 9 years after the index surgery. This report highlights the fact that wire migration can occur long after fracture healing and be relatively asymptomatic. But because the complications of wire migration can be deadly, it requires diligence on the part of the physician to educate the patient that new knee pain after operative fixation requires formal evaluation by the treating surgeon...

Acinetobacter baumannii is an emerging gram-negative nosocomial pathogen that rarely causes infections in orthopaedic patients. We report a case of imipenem-resistant Acinetobacter baumannii paraarticular infection of the knee occurring in a healthy patient following one ambulatory steroid injection for the treatment of quadriceps tendinopathy. The infection was reduced by early surgical debridement of infected tissues, abscess drainage, and prolonged antibiotic therapy with colistin. To our knowledge, this is the first case in the literature reporting such an infection following single steroid injection in orthopaedic patients...

Distal radius fractures are among the most commonly encountered fractures in the extremities. Volar plating of distal radius fracture has gained popularity in recent years with the introduction of the locked plating system. Complications of volar plating include extensor and flexor tendon rupture. Here we present a case report of an extensor indicis proprius and extensor digitorum communis to index finger tendon rupture after open reduction and internal fixation of distal radius fracture with locked plate.

Although bilateral anterior dislocation of shoulder is not that uncommon, there have been only 12 published reports on bilateral anterior fracture dislocation of shoulder. The associated fractures have mostly been greater tuberosity fractures with bilateral three part fractures being reported in only two cases. To our knowledge, a bilateral four part anterior fracture dislocation of the shoulder has not yet been reported in the English literature. We here report a case of bilateral anterior fracture dislocation with four part fracture of both proximal humeri in a 60-year-old male due to electrocution...

A 29-year-old female presented with pain and a palpable mass in the left wrist. Imaging demonstrated a multiloculated cystic mass adjacent to the radial aspect of the scaphoid, which was intimately associated with and appeared to arise from the wall of the radial artery and its dorsal branch. The mass was surgically resected. The histological analysis confirmed the presence of adventitial cystic disease (ACD) of the radial artery. In addition, within a year time span, a second 34-year-old male patient presented with a palpable mass in the right hand...

The footprint is thought to be an important fact in rotator cuff repairs and has been used to compare various cuff fixation techniques. The following experiment used two different measurement sensors to evaluate the footprint as it is affected by suture tensions in a transosseous equivalent suture bridge repair. It was found that suture tension has a direct effect on footprint contact area and pressure and thus could affect healing and fixation stability and should be characterized in any study of comparative fixation techniques...

Spine Tango is currently the only international spine registry in existence. It was developed under the auspices of Eurospine, the Spine Society of Europe, and is hosted at the University of Bern, Switzerland. The HJD Spine Center successfully tested Spine Tango during a 3-month pilot study and has since expanded documentation activities to more surgeons. Workflow integration and dedicated research staff are key factors for such an endeavor. Participation enables benchmarking against national and international peers and outcome research and quality assurance of surgical and non-surgical treatments...

Recent resurgence in the interest of barbed suture has extended its application to wound closures in total joint surgery. Improved suture biomaterials and barb geometry has lead to consideration for its use in various orthopedic procedures including arthroplasty. The reported superior wound tensile stress distribution, no need for knots, and ability to close multiple layers with one suture make it an attractive option for deep wound closure after total joint surgery. However, inherent to the design of this suture are barbs that pose a risk of glove perforation and the potential for the transmission of blood borne pathogens...

PURPOSE: Our aim was to determine whether the administration of intravenous tranexamic acid is a safe and effective means of reducing blood loss associated with hip and knee replacement surgery. METHOD: Sequential cohort study analysing hemoglobin titers, transfusion rates, and the occurrence of venous thromboembolism in patients undergoing hip and knee replacements with and without the administration of tranexamic acid at the time of induction. Finally, a cost benefit analysis was performed...

PURPOSE: Accurate prediction of autograft size for anterior cruciate ligament reconstruction can assist in preoperative planning and decision-making regarding graft choices. This study seeks to determine the accuracy of MRI measurements by comparing intraoperative measurements of the patella, semitendinosis, and gracilis tendons while correlating these measurements with patient anthropometric data such as gender, height, and weight. METHODS: A series of 20 consecutive patients were enrolled who underwent a magnetic resonance imaging study of the knee and proceeded with surgical reconstruction of the anterior cruciate ligament...

Incidental bone tumors are, by definition, asymptomatic lesions that are discovered through routine radiographs obtained for other reasons. Generally, these lesions are benign and latent, requiring no further intervention except observation. However, occasionally these radiographs will detect benign aggressive processes or even malignant lesions that do require further treatment and referral to a tumor specialist. Oftentimes, there are characteristic findings on radiographs that are pathognomonic. Knowledge of these findings can simplify the treatment algorithm for a practicing general orthopaedist...

UNLABELLED: Although the presence of patellar tilt usually implies a tight lateral retinaculum and unhealthy pressure distributions within the patellar cartilage, it is possible for the bony portion of the patella to appear tilted while the articular cartilage is in fact fully congruous in a medial-lateral direction. We call this "congruous tilt." In such cases, a patient may not suffer from an excessive lateral pressure phenomenon, despite the presence of tilt. MATERIALS AND METHODS: One hundred and forty-nine knee MRIs were evaluated with respect to patellar tilt and Wiberg morphology...

PURPOSE: Nonunions of the upper and lower extremity have been associated with pain and functional deficits. Recent studies have demonstrated that healing of these nonunions is associated with pain relief and both subjective and objective functional improvement. The purpose of this study was to determine which patient and surgical factors correlated with successful healing of a nonunion following surgical intervention. METHODS: Between September 2004 and February 2008, all patients with a "long bone nonunion" presenting to our academic trauma service were enrolled in a prospective data base...

Indications for the use of osteochondral allografts for orthopaedic surgical applications are increasing with improved surgical techniques and advancing experience. Modern tissue banks have developed harvesting, processing, and storage methods that ensure an adequate, safe supply of grafts. Continued research is necessary to find a technique that maximizes chondrocyte viability and metabolism both during storage and implantation. The majority of published data on the use of osteochondral allografts has focused on the management of osteochondral defects about the knee...

The patient history often provides the most important information in diagnosis and management of rheumatoid arthritis (RA) and other rheumatic diseases. A multidimensional health assessment questionnaire (MDHAQ)-with templates to score RAPID3 (routine assessment the patient index data), an index of three patient self-report measures, physical function, pain, and patient global estimate-pro- vides a "scientific" patient history. MDHAQ/RAPID3 scores meet criteria for the scientific method seen for laboratory tests: standard format, quantitative data, protocol for col- lection, and recognition of prognostic implications of levels for management decisions...

Glucocorticoids form a mainstay of therapy for rheumatoid arthritis (RA) and other conditions since they exert strong anti-inflammatory, immunosuppressive, and disease-modifying therapeutic effects. However, there is increasing awareness of the potential for these drugs to produce adverse effects. Therefore, improvement of the glucocorticoid benefit-risk ratio represents both a current need and an ongoing challenge. The development of recommendations to implement a more effective and safer use of these important drugs is one useful path to pursue...

Despite over 60 years of use, glucocorticoids continue to be a controversial therapy in rheumatoid arthritis (RA). This stems largely from their measured a well as their perceived toxicity. However, a paucity of top tier evidence from clinical trials or very carefully controlled observational studies leads to limited evidence supporting potential causal relations between low-dose glucocorticoids and adverse outcomes. Several new studies have contributed to an improved understanding of these associations and they are reviewed here along with highlights from the older body of literature examining these important outcomes...

The efficacy of initial and long-term prednisone < 5 mg/ day in treatment of rheumatoid arthritis (RA) by one academic rheumatologist over 25 years from 1980 to 2004 is summarized. Patient responses were assessed using a multidimensional health assessment questionnaire (MDHAQ), completed by all patients at all visits in the infrastructure of care. A database was maintained of all visits, which included medications and scores for physical function, pain, patient global estimate of status, and routine assessment of patient index data (RAPID3), an index of these 3 measures...
