Hemiarthroplasty versus total shoulder arthroplasty in B2 glenoids with an intact rotator cuff: a long-term matched cohort analysis.

Background: Walch B2 glenoids present unique challenges to the shoulder arthroplasty surgeon, particularly in young, active patients who may wish to avoid the restrictions typically associated with an anatomic total shoulder arthroplasty (TSA). Long-term data are limited when comparing hemiarthroplasty (HA) and TSA for patients with an intact rotator cuff. The purpose of our study was to compare the long-term outcomes of HA vs.

Outcomes Following Primary Anterior Cruciate Ligament Reconstruction Using a Partial Transphyseal (Over-the-Top) Technique in Skeletally Immature Patients.

Background: The incidence of anterior cruciate ligament (ACL) injuries in skeletally immature patients is increasing, with ACL reconstruction preferred in this population due to reported chondroprotective benefits. Due to concerns with growth disturbance following ACL reconstruction in skeletally immature patients, various physealsparing and partial transphyseal techniques have been developed. Currently, there is no consensus on the most effective ACL reconstruction technique in skeletally immature patients.

Outcomes of a technique combining diaphyseal impaction grafting and metaphyseal cones for severe bone loss in revision total knee arthroplasty.

Aims: Metaphyseal cones with cemented stems are frequently used in revision total knee arthroplasty (TKA). However, if the diaphysis has been previously violated, the resultant sclerotic canal can impair cemented stem fixation, which is vital for bone ingrowth into the cone, and long-term fixation. We report the outcomes of our solution to this problem, in which impaction grafting and a cemented stem in the diaphysis is combined with an uncemented metaphyseal cone, for revision TKA in patients with severely compromised bone.

Prospective evaluation of lateral femoral cutaneous nerve injuries during periacetabular osteotomy.

Periacetabular osteotomies (PAOs) are used to treat acetabular dysplasia in younger patients, but are not without morbidity. Lateral femoral cutaneous nerve (LFCN) injuries are commonly associated with the approach for PAOs, but the true incidence and rate of resolution is not known. The purpose of this prospective study was to determine the incidence of LFCN injuries after PAO using an innovative nerve conduction study (NCS) and to report the patient-reported outcomes.

Botox and Thumb MCP Radial Collateral Ligament Reconstruction.

 We report the use of botulinum toxin to aid in the treatment of chronic radial collateral ligament insufficiency of the thumb.  Treatment included autograft tendon reconstruction and cast immobilization. Six weeks postoperatively, prior to hand therapy, the patient underwent an ultrasound-guided botulinum neurotoxin A injection into the adductor pollicis muscle to negate its deforming forces on the reconstruction.

Medial Patellofemoral Ligament Reconstruction Reduces Radiographic Measures of Patella Alta in Adults.

Background: Patellar height has long been considered a risk factor for patellofemoral instability. However, recent pediatric literature demonstrated a reduction in patellar height measurements following medial patellofemoral ligament (MPFL) reconstruction.

Purpose: To assess the mean change in patellar height and the percentage of skeletally mature patients with patellar height ratios reduced to within-normal limits following MPFL reconstruction.

Multiple Volar Carpometacarpal Dislocations: Case Report/Review of the Literature.

Simultaneous volar dislocations of the second through fifth carpometacarpal joints are rare injuries, usually a result of high-energy trauma to the hand. The literature regarding this topic is sparse and consists primarily of case reports. We present a case associated with median nerve contusion that was treated with open reduction and pin fixation.

Return to sport: Does excellent 6-month strength and function following ACL reconstruction predict midterm outcomes?

Purpose: The purpose of this study was to determine whether patients with excellent 6-month functional testing after ACL reconstruction had (1) higher risk of subsequent ACL tears, (2) superior knee function, and (3) increased activity levels compared to those with delayed clearance for return to sports at midterm follow-up.

Methods: A total of 223 patients underwent primary ACL reconstruction by a single surgeon and had functional and isokinetic testing performed 6 months post-operatively between 1998 and 2005. Of the 223 patients, 52 (23 %) made the excellent group and were allowed return to sport at 6 months, and the remaining 171 (77 %) constituted the delayed group.

Growth arrest of the capitellar physis after displaced lateral condyle fractures in children.

Background: Fractures of the lateral humeral condyle represent the second most common elbow fracture in children and the most common physeal fracture about the elbow. Growth disturbances after this fracture, including premature physeal arrest, are rare but important complications. Only 4 radiographically documented reports of premature physeal arrest exist to date with just 1 offering comparative views.

Knee injuries and the use of prophylactic knee bracing in off-road motorcycling: results of a large-scale epidemiological study.

Background: The effectiveness of prophylactic knee bracing in preventing knee injuries during sports has been evaluated; however, because of the variability in study conclusions, the topic remains controversial. Despite a paucity of data, the authors believe that prophylactic knee bracing is frequently used in off-road motorcycling.

Hypothesis: No statistically significant difference exists in the frequency and types of knee injuries incurred between braced and nonbraced riders using commercially available knee braces in off-road motorcycling.
