Hemiarthroplasty for the treatment of distal humerus fractures: long-term clinical results.

Background: Total elbow arthroplasty is a treatment for unreconstructable distal humerus fractures; implant longevity remains a concern, especially in younger patients. However, distal humeral hemiarthroplasty (DHH) offers an alternative with potential long-term advantages.

Methods: This is a retrospective study of 10 patients who underwent DHH for distal humerus fractures over a 4-year period (2008-2012) by a single surgeon.

Validation of new shoulder periprosthetic joint infection criteria.

Background: A periprosthetic joint infection (PJI) in the shoulder can be difficult to diagnose. Many variables have been used to determine a PJI. Recently, the 2018 International Consensus Meeting (ICM) on orthopedic infections gave new criteria to help identify PJI in the shoulder.

Distal tibia allograft glenoid reconstruction for shoulder instability: outcomes after lesser tuberosity osteotomy.

Background: Distal tibia allograft reconstruction of the glenoid in shoulder instability has garnered significant attention over the last decade. Prior studies demonstrate significant improvement in all reported patient outcomes albeit the approach is through a subscapularis split. There have not been prior studies evaluating outcomes after lesser tuberosity osteotomy which provides excellent exposure to the anterior glenoid.

Anatomic reconstruction of acromioclavicular joint dislocations using allograft and synthetic ligament.

Background: Acromioclavicular (AC) separations are commonly seen shoulder injuries. Numerous surgical reconstruction techniques have been described. In this study, we present a series of patients who underwent an anatomic reconstruction using a synthetic ligament and allograft construct.

Early results of reverse total shoulder arthroplasty using a patient-matched glenoid implant for severe glenoid bone deficiency.

Background: Reverse total shoulder arthroplasty (rTSA) in the presence of significant glenoid bone loss remains a challenge. This study presents preliminary clinical and radiographic outcomes of primary and revision rTSA using a patient-matched, 3-dimensionally printed custom metal glenoid implant to address severe glenoid bone deficiency.

Methods: Between September 2017 and November 2018, 19 patients with severe glenoid bone deficiency underwent primary (n = 9) or revision rTSA (n = 10) using the Comprehensive Vault Reconstruction System (VRS) (Zimmer Biomet, Warsaw, IN, USA) at a single institution.

Variations of magnetic resonance imaging findings in asymptomatic elbows.

Background: Magnetic resonance imaging (MRI) findings in asymptomatic patients have been described for hips, knees, ankles, shoulders, and intervertebral disks. No such description exists for the elbow.

Methods: MRI scans of 189 asymptomatic elbows divided into 3 groups by age (group 1, 20-39 years; group 2, 40-59 years; and group 3, ≥60 years) were evaluated for abnormalities within 13 anatomic structures using a novel classification system.
