Differences in glenohumeral joint morphology between patients with anterior shoulder instability and healthy, uninjured volunteers.
Traumatic glenohumeral joint (GHJ) dislocations are common, resulting in significant shoulder disability and pain. Previous research indicates that bony morphology is associated with an increased risk of injury in other joints (eg, the knee), but the extent to which bony morphology is associated with traumatic GHJ dislocation is unknown. This study assessed GHJ morphology in patients with anterior GHJ instability and in a control population of healthy volunteers. ⋯ There are significant differences in GHJ morphology between healthy control subjects and both shoulders (injured and uninjured, contralateral) of patients diagnosed with anterior instability after GHJ dislocation. These findings are important clinically because they suggest that glenoid morphology may influence the risk of GHJ dislocation.

Scapulohumeral rhythm in shoulders with reverse shoulder arthroplasty.
Little is known about kinematic function of reverse total shoulder arthroplasty (RTSA). Scapulohumeral rhythm (SHR) is a common metric for assessing muscle function and shoulder joint motion. The purpose of this study was to compare SHR in shoulders with RTSA to normal shoulders. ⋯ RTSA shoulders show kinematics that are significantly different from normal shoulders. SHR in RTSA shoulders was significantly lower than in normal shoulders, indicating that RTSA shoulders use more scapulothoracic motion and less glenohumeral motion to elevate the arm. With these observations, it may be possible to improve rehabilitation protocols, with particular attention to the periscapular muscles, and implant design or placement to optimize functional outcomes in shoulders with RTSA.

Randomized Controlled Trial Comparative StudyCompressive cryotherapy versus ice-a prospective, randomized study on postoperative pain in patients undergoing arthroscopic rotator cuff repair or subacromial decompression.
The purpose of this study was to compare the effect of compressive cryotherapy (CC) vs. ice on postoperative pain in patients undergoing shoulder arthroscopy for rotator cuff repair or subacromial decompression. A commercial device was used for postoperative CC. A standard ice wrap (IW) was used for postoperative cryotherapy alone. ⋯ There does not appear to be a significant benefit to use of CC over standard IW in patients undergoing shoulder arthroscopy for rotator cuff repair or subacromial decompression. Further study is needed to determine if CC devices are a cost-effective option for postoperative pain management in this population of patients.

Comparative StudyGeriatric proximal humeral fracture patients show similar clinical outcomes to non-geriatric patients after osteosynthesis with endosteal fibular strut allograft augmentation.
Osteosynthesis of proximal humeral fractures is challenging in geriatric patients. The purpose of this investigation was to compare postoperative clinical outcomes between cohorts of geriatric (aged ≥65 years) and non-geriatric proximal humeral fracture patients treated via locked plating with endosteal fibular strut allograft augmentation. ⋯ Osteosynthesis of proximal humeral fractures via locked plating with fibular strut allograft augmentation results in similar clinical outcomes between geriatric and non-geriatric patients. We believe that enhanced stability provided by this fixation construct allows early intensive postoperative therapy and results in excellent outcomes despite patient age.

Open Bankart repair for revision of failed prior stabilization: outcome analysis at a mean of more than 10 years.
The purpose of this study was to analyze the outcome of open Bankart repair for failed stabilization surgery at a mean follow-up of >10 years. ⋯ The open Bankart repair offers a reliable, consistently successful option for revision of failed stabilizations.
