Low injury incidence and excellent return to sport after injuries in beach handball-a cross-sectional survey of 651 athletes.

Background: To quantify the five-year injury incidence and to identify risk factors and common injury patterns in beach handball athletes. It was hypothesized that there would be a low incidence of injuries with identifiable risk and preventative factors.

Methods: An online survey was conducted among active beach handball athletes from 08-09/2022.

Long-term Follow-up After Arthroscopically Assisted 2-Bundle Anatomic Reduction of Acute Acromioclavicular Joint Separations.

Background: Arthroscopically assisted techniques for acromioclavicular joint reconstruction have increasingly been used over the past 15 years. Long-term results are lacking.

Hypothesis: Patients will continue to show good clinical function and sustained anatomic reduction at long-term follow-up.

Clinical and radiographical outcomes of scapular spine fractures after reverse shoulder arthroplasty treated with double plating and autologous bone graft.

Background: Scapular spine fractures (SSFs) are a challenging complication after reverse total shoulder arthroplasty (rTSA) leading to persisting pain, loss of function, and instability. So far there is no established uniform surgical procedure for successful treatment.

Methods: Single-center consecutive cohort study of 25 surgically treated SSFs after rTSA between 2016 and 2021.

Off-season beach handball participation lowers injury incidence among handball players-A cross-sectional survey on 641 athletes.

Purpose: To assess the effect of beach handball training during the indoor handball off-season on the incidence of indoor handball injuries over three seasons. It was hypothesised that off-season beach handball training would be associated with a lower injury incidence in indoor handball season.

Methods: An online survey of indoor handball athletes was distributed between 04-06/2023.

Pyrocarbon hemiprostheses show little glenoid erosion and good clinical function at 5.5 years of follow-up.

Background: The success of traditional shoulder hemiarthroplasty (HA) with cobalt-chromium heads is limited by painful glenoid erosion with problematic bone loss. Hemiprostheses with pyrolytic carbon (PyC) heads have shown reduced glenoid erosion in experimental laboratory studies. Few in vivo data are available.

Validation of a novel 3-dimensional classification for degenerative arthritis of the shoulder.

Introduction: A novel three-dimensional classification to comprehensively describe degenerative arthritis of the shoulder (DAS) was recently published by our group. The purpose of the present work was to investigate intra- and interobserver agreement as well as validity for the three-dimensional classification.

Materials And Methods: Preoperative computed tomography (CT) scans of 100 patients who had undergone shoulder arthroplasty for DAS were randomly selected.

A shallow morphology of the intertubercular groove is associated with medial and bilateral but not lateral pulley lesions.

Purpose: To investigate the influence of intertubercular groove (IG) morphology on the development of different types of biceps reflection pulley (BRP) injuries.

Methods: A consecutive cohort of 221 patients with ventral shoulder pain and a preoperative diagnosis suspecting BRP injury, who underwent arthroscopy, was retrospectively reviewed. The presence or absence as well as type of pulley injury (medial, lateral or bilateral) was confirmed arthroscopically.

A 3-Dimensional Classification for Degenerative Glenohumeral Arthritis Based on Humeroscapular Alignment.

Background: Seminal classifications of degenerative arthritis of the shoulder (DAS) describe either cuff tear arthropathy in the coronal plane or primary osteoarthritis in the cross-sectional plane. None consider a biplanar eccentricity.

Purpose/hypothesis: The purpose of this study was to investigate humeroscapular alignment (HSA) of patients with DAS in both the anteroposterior (A-P) and superoinferior (S-I) planes on computed tomography (CT) after 3-dimensional (3D) reconstruction and develop a classification based on biplanar HSA in 9 quadrants.

Midterm outcome and strength assessment after quadriceps tendon refixation with suture anchors.

Purpose: Quadriceps tendon ruptures (QTR) occur predominantly in middle-aged patients through violent eccentric contraction that occurs either when trying to regain balance or during a fall on the hyperflexed knee. The aim of this study was to quantify midterm postoperative results, including strength potential measured via standardized strength tests following acute (< six weeks) quadriceps tendon refixation using suture anchors.

Methods: All consecutive patients with QTR who underwent surgical suture anchor refixation between 2012 and 2019 at a single institution with a minimum follow-up of 12 months were retrospectively evaluated.

Pectoralis major and pectoralis minor transfer for irreparable subscapularis tendon tears.

Objective: Irreparable rotator cuff injuries in young patients with moderate to high levels of physical activity remain a challenging pathology for shoulder surgeons. Irreparable anterior rotator cuff injuries require treatment that seeks to restore the dynamic anterior forces of the glenohumeral joint. Among surgical treatment options, transfer of the pectoralis major and minor muscle, have shown good functional outcomes.

Injury Patterns, Risk Factors, and Return to Sport in Brazilian Jiu Jitsu: A Cross-sectional Survey of 1140 Athletes.

Background: Brazilian jiu jitsu (BJJ) is a growing martial art that focuses on grappling techniques.

Purpose: To quantify the 3-year incidence of BJJ-related injuries and detect common injury patterns as well as risk factors among those practicing BJJ. It was hypothesized that there would be a high incidence of injuries, they would be caused by submissions in sparring situations, and they would occur predominantly at the extremities.

Midterm outcome and strength assessment after proximal rectus femoris refixation in athletes.

Purpose: Proximal rectus femoris avulsions (PRFA) are relatively rare injuries that occur predominantly among young soccer players. The aim of this study was to evaluate midterm postoperative results including strength potential via standardized strength measurements after proximal rectus femoris tendon refixation. It was hypothesized that the majority of competitive athletes return to competition (RTC) after refixation of the rectus femoris tendon without significant strength or functional deficits compared to the contralateral side.

[Acute rupture of the pectoralis major muscle at the musculotendinous junction : Case report of a rare injury and literature review].

Rupture of the pectoralis major muscle (PMR) is a rare injury that occurs primarily during strength training. The case of a 31-year-old professional basketball player who suffered a rupture of the pectoralis major muscle (PM) at the myotendinous junction while performing bench presses is presented. Due to persistent pain and decreased muscle function, surgery was performed 3 weeks after the initial trauma.

RSA, TSA and PyC hemi-prostheses: comparing indications and clinical outcomes using a second-generation modular short-stem shoulder prosthesis.

Introduction: The goal of this study was to provide an insight into the clinical results after modular short-stem shoulder arthroplasty for various indications.

Materials And Methods: A consecutive cohort study of 76 patients followed up for 23-55 (mean 31.4) months.

Cementless curved short stem shoulder prostheses with a proximal porous coating: ingrowth properties at 2-5 years of radiological follow-up with clinical correlation.

Background: Little is known about the way the newest generation of stems integrate into the proximal humerus and their effect on the surrounding bone. Factors that may influence ingrowth have not been investigated.

Methods: A consecutive cohort study was conducted that examined 74 anatomical, reverse, or pyrocarbon hemiprostheses, using a curved modular short stem with a proximal porous coating 2-5 years postoperatively (mean 35 months).
