Background: Subacromial space distance and forward head and shoulder posture are common characteristics resulting from swim training. These alterations can cause abnormal scapular kinematics and positioning, potentially increasing compression of structures in the subacromial space and increasing the risk for the development of swimmer's shoulder.
Purpose: To evaluate the effect of the swim training season on subacromial space distance and forward head and forward shoulder posture as well as to determine the relationship between these variables.
Study Design: Cohort study; Level of evidence, 2.
Methods: Included in the study were 43 competitive adolescent swimmers and 29 nonoverhead adolescent athletes (controls) who were not currently experiencing any shoulder, neck, or back pain that limited their participation in sports activity. All participants were evaluated 3 times: once before the start of the swim training season and then at 2 follow-up sessions 6 and 12 weeks after the initial testing session. At each testing session, each participant completed a physical examination that included evaluation of posture and subacromial space distance.
Results: Swimmers had significantly greater decreases in subacromial space distance during the training season compared with nonoverhead athletes. Swimmers also demonstrated significantly greater increases in forward shoulder posture compared with nonoverhead athletes. A significant relationship was noted between changes in forward shoulder posture and changes in subacromial space distance from the baseline testing session to the assessment 6 weeks after baseline assessment. As forward shoulder posture increased, subacromial space significantly decreased.
Conclusion: Because of their training load, swimmers experience a decrease in subacromial space distance and an increase in forward shoulder posture over the course of 12 weeks of training, potentially making these athletes more vulnerable to the development of shoulder pain and injury.

Subacromial Distal Clavicle Dislocation with Associated Scapular Spine Fracture: A Case Report.
J Orthop Case Rep

Introduction: Inferior or subacromial dislocation of the distal clavicle is a rare entity. Previous reports of this injury pattern have largely been limited to Rockwood VI acromioclavicular joint (AC) dislocations, with the distal clavicle located in the subcoracoid position. Few case reports have been described with the inferior clavicle being located in the subacromial space, and these have all been previously associated with clavicle fractures.

Context: Limited information exists regarding the immediate and short-term effects of scapula retraction exercises (SREs) on acromiohumeral distance (AHD) in subacromial pain syndrome (SPS). This study's 2 main objectives were to investigate (1) the immediate effect of the SRE on AHD at varying shoulder abduction angles in patients with SPS and healthy controls and (2) the effect of the 8-week SRE program on AHD in patients with SPS.
Design: Cross-sectional and pre-post intervention designs were utilized on this study.
Remplissage Using Percutaneous Needle Navigation With Knotless Anchors in a Suture Staple Configuration.
Arthrosc Tech
December 2024
Division of Sports Medicine, Department of Orthopaedic Surgery, Virginia Commonwealth University Health Systems, Richmond, Virginia, U.S.A.
Remplissage is a procedure that decreases the rate of recurrent instability after arthroscopic stabilization in patients with an engaging Hill-Sachs lesion. This technique involves capsulotenodesis of the infraspinatus tendon and posterior capsule into the Hill-Sachs lesion using 2 knotless anchors with suture passage through the infraspinatus tendon guided by a percutaneous needle. Previously described techniques use knots or anchor placement through the infraspinatus, which can be challenging to control and irreversible if tendon penetration occurs in an undesirable location.

Objectives: To determine the prevalence of acromioclavicular (AC) joint and subacromial space imaging abnormalities in asymptomatic adults, with a secondary objective of comparing findings between asymptomatic and symptomatic shoulders within the same study populations.
Methods: We conducted a systematic review of studies examining shoulder imaging abnormalities detected by X-ray, ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) in asymptomatic adults (PROSPERO registration CRD42018090041). This report focuses on AC joint and subacromial space abnormalities.

Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, Daegu, Republic of Korea.
Background: Human placental hydrolysate (hPH) contains anti-inflammatory substances. This study aimed to analyze whether injecting hPH into the subacromial space could reduce pain in patients with shoulder impingement syndrome.
Methods: This single-blind, randomized controlled study enrolled 50 patients with shoulder impingement syndrome who were randomly assigned to either the hPH or placebo groups.
