Bone tunnel widening poses a problem for graft fixation during revision anterior cruciate ligament (ACL) reconstruction. Large variability exists in the utilization of imaging modalities for evaluating bone tunnels in pre-operative planning for revision ACL reconstruction. The purpose of this study was to identify the most reliable imaging modality for(More)
Acromioclavicular (AC) joint injuries are common in athletic populations and account for 40% to 50% of shoulder injuries in many contact sports, including lacrosse, hockey, rugby and football. The AC joint is stabilized by static and dynamic restraints, including the coracoclavicular (CC) ligaments. Knowledge of these supporting structures is important when(More)
BACKGROUND The management of anterior cruciate ligament (ACL) tears in the skeletally immature patient remains controversial. Outcomes on a physeal-sparing technique using the iliotibial band for combined intra-articular and extra-articular ACL reconstruction, called the Micheli technique, have been described and reported by the original authors. PURPOSE(More)
The purpose of this study was to document outcomes following microfracture for full-thickness cartilage defects of the knee in adolescents. Our hypothesis was that patients aged 18 years or less would have excellent outcomes and function following microfracture of full-thickness knee articular cartilage defects. This study was approved by the Institutional(More)
OBJECTIVES There is a recent trend toward increased surgical treatment of displaced midshaft clavicle fractures in adolescents. The primary purpose of this study was to evaluate the intrarater and interrater reliability of clavicle fracture classification systems and measurements of displacement, shortening, and angulation in adolescents. The secondary(More)
The purpose of this study was to evaluate possible risk factors for symptomatic adhesions after hip arthroscopy. Data were analysed from hip arthroscopies performed between 2005 and 2009. Only primary hip arthroscopies were included. Data collected included demographics, primary treatment, rehabilitation, revision surgery, and presence of adhesions at(More)
It is predicted that the number of revision hip and knee arthroplasties will double by the years 2026 and 2015, respectively. As the burden of end-stage prosthetic disease increases, there will be a greater potential need for total femoral arthroplasty. This report describes a patient with a femoral neck fracture nonunion with an ipsilateral multiply(More)

BACKGROUND AND PURPOSE In gymnastics, the wrist is exposed to many different stresses including increased extension, especially during back handsprings. Currently a wrist extension angle during impact that places the wrist in danger has not been established. The purpose of this study was to: (1) determine the mean impact wrist angle during a standing back(More)
