The age specific performance of elbow hemiarthroplasty: A systematic review.

Background: Compared to total elbow arthroplasty, elbow hemiarthroplasty (EHA) does not have an ulnar component or a hinge/link which eliminates complication risk due to polyethylene wear and ulnar loosening. There are notable gaps in the existing EHA literature. Patient age is often identified as an important determinant when deciding to treat with EHA; however, there is limited age-based evidence.

Characterizations of Capsule Closure in Hip Arthroscopy Are Infrequently and Incompletely Reported: A Systematic Review.

Purpose: To review the recent literature to provide an updated characterization of capsule closure techniques in hip arthroscopy and to determine if the characteristics of closure impacted clinical outcomes.

Methods: In keeping with the Preferred Reporting in Systematic Reviews and Meta Analyses (PRISMA) guidelines, a systematic review was performed with the following eligibility criteria: patients over 18 years of age who underwent primary hip arthroscopy with reporting of patient reported outcome measures or revision/failure, and a sufficiently detailed description of capsule closure. The GRADE framework evaluated study quality, and ROBINS-I evaluated the risk of bias.

Clinical outcomes for linked fixation of distal humerus fractures: a multicenter study.

Background: O'Driscoll popularized the principle of linked column fixation for distal humerus fractures. Despite the linked column concept being widely accepted, there are few reported techniques to accomplish this goal. A novel device was designed based on the principles of linked columns.

Comparing internal and external stabilization for traumatic elbow instability: a systematic review.

Background: Despite surgical reestablishment of the supporting structures, instability may often persist in traumatic elbow injury. In these cases, a temporary internal or external fixator may be indicated to unload the repaired structures and maintain joint concentricity. Aggregate data are needed to characterize the risk of complication between external fixation (ExFix) and the internal joint stabilizer (IJS) when used for traumatic elbow instability.

The impact of anatomic alignment on radiocapitellar pressure following radial head arthroplasty.

Background: The incidence of radial head fractures is increasing, and radial head arthroplasty (RHA) is being more frequently used as treatment for irreparable fractures. Our objective was to compare radiocapitellar pressure between the native joint and 2 radial head prosthesis conditions: (1) a prosthetic head that was aligned to the forearm axis of rotation and (2) the same prosthesis with an axisymmetric nonaligned head.

Methods: Ten cadaveric specimens received a pressfit radial head prosthesis (Align; Skeletal Dynamics) for both prosthetic testing conditions.

Resident Impact on Primary Total Knee Arthroplasty: A Consecutive Series Under a Single Surgeon.

Background: The literature has displayed conflicting evidence on resident involvement in surgical procedures. The goal of this study was to assess the impact of resident involvement on primary total knee arthroplasty (TKA) under a single fellowship-trained adult reconstruction surgeon.

Methods: Two hundred sequential patients were retrospectively reviewed by a single surgeon: the first cohort represented the final 100 TKAs performed by the surgeon without resident involvement (NRI), serving as the control group, and the second cohort represented the initial 100 TKAs performed by the same surgeon with resident involvement (RI), serving as the experimental group.

Linking the distal humerus columns in articular fracture fixation.

Introduction: Concerning rates of nonunion in articular distal humerus fractures indicate an unsolved problem. The fixation principles of O'Driscoll describe linking the fractured articular segment to the distal humerus columns with compression screws which creates a stable fixed angle construct. A novel device has been introduced which utilizes an interlocking beam through the articular segment to connect the distal aspect of the medial and lateral plates, creating a linked construct.

Multifocal eosinophilic granuloma with femoral epiphyseal lesion mimicking an aneurysmal bone cyst.

Eosinophilic granuloma (EG) is a rare benign tumor-like disorder characterized by abnormal proliferation Langerhans cells. EG frequently presents as a solitary lesion in the axial skeleton and diaphysis long bones. Here we present the case of a 14-year-old male with multifocal EG with a lesion located in the femoral epiphysis mimicking an aneurysmal bone cyst that presented a diagnostic challenge.

Sclerosis of the clavicle--A challenging diagnosis.

Condensing osteitis of the clavicle is a rare benign disease described as an increase in bone density at the medial end of the clavicle. Its clinical and radiographic presentation can frequently be equivocal and tissue sampling is necessary for diagnostic confirmation. Here we present the case of a 29-year-old female with condensing osteitis of the right medical clavicle, who remained undiagnosed for many years despite obtaining imaging studies and undergoing an initial biopsy.
