Comparison of the rate of delayed/nonunion in fifth metatarsal fractures receiving anti-inflammatory medications.

Purpose: Controversy exists regarding the acute effect of non-steroidal anti-inflammatory drugs (NSAIDs) on early fracture healing. The purpose of this study was to analyze the rate of nonunion or delayed union in patients with fifth metatarsal (5 MT) fractures. We hypothesize that the use of NSAIDs would increase the rate of nonunion/delayed union in 5 MT fractures.

The Key Pinch Stress Radiograph to Evaluate Dorsal Subluxation in the Basilar Thumb Joint.

The basilar thumb joint is the joint second most commonly affected by osteoarthritis (OA) in the hand. Evaluation of dorsal subluxation of the thumb during a functional task such as key pinch could help assess OA risk. The objectives of this study were to determine the best imaging angle for measuring thumb dorsal subluxation during key pinch and to compare subluxation to corresponding OA grades on the Eaton-Glickel, Outerbridge, and International Cartilage Repair Society scales.

Comparison of Postoperative Anatomy Using Anatomic Total Shoulder Arthroplasty Versus Soft-Tissue Balancing Total Shoulder Arthroplasty.

Background: The importance of anatomic reconstruction of the proximal humerus on shoulder biomechanics and kinematics after anatomic total shoulder replacement (aTSR) has been highlighted by a number of investigations. The humeral head designs of current-generation shoulder arthroplasty emphasize either anatomic or soft-tissue balancing total shoulder arthroplasty (sbTSR) philosophies. The purpose of this study was to compare the postoperative anatomy of TSR systems used to treat primary glenohumeral osteoarthritis.

Weightbearing Protocols After Posterolateral Corner Reconstruction: A Systematic Review.

Background: Multiligamentous knee injuries with a posterolateral corner injury represent a devastating insult to the knee.

Purpose: To evaluate multiligamentous knee reconstruction rehabilitation programs and recommend a rehabilitation program based on a review of published outcomes studies.

Study Design: Systematic review; Level of evidence, 4.

Nationwide Analysis of Total Ankle Replacement and Ankle Arthrodesis in Medicare Patients: Trends, Complications, and Cost.

Background: Surgical management of end-stage ankle arthritis consists of either ankle arthrodesis (AA) or total ankle replacement (TAR). The purpose of this study was to evaluate utilization trends in TAR and AA and compare cost and complications.

Methods: Medicare patients with the diagnosis of ankle arthritis were reviewed.

The Effect of the Joint Capsule and Anterior Oblique Ligament on Dorsal Subluxation of the First Metacarpal During Key Pinch.

Laxity of the anterior oblique ligament (AOL) and/or the dorsoradial ligament (DRL) are believed to contribute to the progression of osteoarthritis in the trapeziometacarpal joint through increased dorsal subluxation. Stress radiographs during functional tasks, such as key pinch, can be used to evaluate such joint instability. Cadaveric experiments can explore joint contact pressures as well as subluxation under varying conditions, to gain knowledge about joint mechanics.

Liposclerosing Myxofibrous Tumor in a Patient with Prostate Cancer: A Case Report.

Case: A 64-year-old man diagnosed with prostate cancer was incidentally found to have a lesion in his distal femur. Although initially concerning for metastatic prostate cancer, after biopsy by an orthopaedic oncology specialist, a diagnosis of liposclerosing myxofibrous tumor (LSMFT) was confirmed. The lesion was treated with curettage and demineralized bone matrix grafting with close follow-up.

Ipsilateral rotational double-barrel fibula autograft for limb salvage in a pediatric patient with lower extremity intramedullary osteosarcoma: A case report.

Osteosarcoma is a relatively uncommon diagnosis that often requires limb salvage techniques in young patients. Due to the potential long-life expectancy of these patients, techniques which avoid prostheses are preferred to limit the need for future revision surgeries. This case report presents a 9-year-old male diagnosed with intramedullary well-differentiated osteosarcoma of the tibial diaphysis.

Increased rates of knee arthroplasty and cost of patients with meniscal tears treated with arthroscopic partial meniscectomy versus non-operative management.

Purpose: The purpose of this study was to determine the cost of arthroscopic partial meniscectomy (APM), one of the most common surgeries performed by orthopaedic surgeons, and the associated rate of progression to knee arthroplasty (KA) compared to patients treated non-operatively after diagnosis of meniscal tear.

Methods: Utilizing data mining software (PearlDiver, Colorado Springs, CO), a national insurance database of approximately 23.5 million orthopaedic patients was queried for patients diagnosed with a meniscal tear.

Simultaneous Bilateral Knee Dislocation During Weight Training: A Case Report and Review of the Literature.

Case: We describe the clinical course and treatment of a patient who sustained simultaneous bilateral knee dislocation under low-velocity atraumatic conditions, and provide a review of the literature. Dislocations of the native knee joint are uncommon orthopaedic injuries but they are true emergencies because of the concern for concomitant neurovascular injury; therefore, they may be limb-threatening injuries.

Conclusion: To our knowledge, there are few reports of simultaneous bilateral knee dislocation and no reports of this occurring during weight training.

Cost comparison and complication rate of Lisfranc injuries treated with open reduction internal fixation versus primary arthrodesis.

Background: Controversy exists regarding optimal primary management of Lisfranc injuries. Whether open reduction internal fixation (ORIF) or primary arthrodesis is superior remains unknown.

Methods: A national insurance database of approximately 23.

The effect of scoliotic deformity on spine kinematics in adolescents.

Background: While adolescent idiopathic scoliosis (AIS) produces well characterized deformation in spinal form, the effect on spinal function, namely mobility, is not well known. Better understanding of scoliotic spinal mobility could yield better treatment targets and diagnoses. The purpose of this study was to characterize the spinal mobility differences due to AIS.

Remote Magnetic Navigation System Guided Radiofrequency Ablation of Intra Atrial Reentrant Tachycardia in Corrected Transposition of Great Arteries.

Atrial arrhythmias are delayed manifestations after atrial switch procedures for d-transposition of the great arteries. Often times, these arrhythmias are intraatrial reentry tachycardias that arise in the pulmonary venous neo-atrium. Access and ablation in the pulmonary venous neo-atrium may require baffle puncture, risking damage to the baffle.
