  • Tibial Tubercle Osteotomy: Indication and Techniques.

    Osteotomy of the tibial tubercle is a versatile procedure that can be utilized for several common pathologies about the patellofemoral joint. Most commonly, tuberosity transfer is employed for the treatment of patellar instability or symptomatic overload of the patella. The osteotomy can be combined with soft tissue realignment procedures or cartilage reconstructive techniques. A precise understanding of the surgical anatomy and the biomechanics of the patellofemoral articulation is essential for producing a successful outcome during surgery.

  • Structural and biomechanical responses of osseous healing: a novel murine nonunion model

    Understanding the biological mechanisms of why certain fractures are at risk for delayed healing or nonunion requires translational animal models that take advantage of transgenic and other genetic manipulation technologies. Reliable murine nonunion models can be an important tool to understand the biology of nonunion. In this study, we report the results of a recently established model for creating critical defects that lead to atrophic nonunions based on a unique fracture fixation technique.

  • Avoiding graft-tunnel length mismatch in anterior cruciate ligament reconstruction: the single-bone plug technique.

    Anterior cruciate ligament reconstruction, using autogenous bone-patellar tendon-bone (BTB) as a graft material, is commonly performed in the setting of anterior cruciate ligament insufficiency. Although bone-patellar tendon-bone autograft has an extensive track record, showing excellent clinical results, donor-site morbidity and graft-tunnel mismatch can still be problematic for a subset of patients.

  • Perioperative risks associated with the operative treatment of clavicle fractures.

    A total of 37 patients treated for a clavicle fracture from January 2007 to December 2008 with at least 12 months' follow-up were identified from a billing code search. At the latest follow-up appointment, the patients completed the Constant Shoulder, the Disabilities of the Arm, Shoulder and Hand scale (DASH) and the Medical Outcomes Study 36-Item Short-Form Health Survey version 2.0 (SF36v2) functional outcome surveys as well as a custom questionnaire to assess hand dominance, employment status, the amount of time taken before returning to work, the presence of numbness around the incision site (a surrogate marker of a supraclavicular nerve palsy), whether the patient desired the plate removed and/or if it was worth another surgery.

  • Functional results of the Darrach procedure: a long-term outcome study.

    A retrospective chart review identified patients who had undergone the Darrach procedure for traumatic or posttraumatic distal radioulnar joint (DRUJ) pathology. We assessed subjective outcomes using a visual analog scale questionnaire to assess pain, wrist stability, and overall satisfaction. We evaluated objective functional outcomes using the Quick Disabilities of the Shoulder, Arm, and Hand and Patient-Rated Wrist Evaluation measures. Final radiographs were compared with preoperative x-rays to investigate the effect of possible ulnar impingement syndrome (convergent instability).
