BACKGROUND: Instability is the most common complication after reverse total shoulder arthroplasty (rTSA). In the native glenohumeral joint, in addition to full dislocations, more subtle forms of instability exist. However, the incidence of more subtle forms of instability, the factors associated with instability, and the effect of instability on validated outcome scores after rTSA remain poorly understood. QUESTIONS/PURPOSES: (1) After rTSA, what is the risk of instability, including more subtle forms of subjective instability? (2) What are the factors associated with instability? (3) Are more subtle forms of instability associated with lower American Shoulder and Elbow Surgeons (ASES) functional outcome scores than those patients without instability? METHODS: A total of 168 rTSAs were performed during the study period...

There is limited evidence to suggest that anterior approaches for the resection of ventral intramedullary lesions of the cervical spinal cord may result in superior neurological outcomes compared with those following more traditional posterior approaches. To the authors' knowledge, no report of an anterior approach to resect a ventral intramedullary capillary hemangioma exists in the literature. In the following paper, the case of a 75-year-old male who presented with progressive neck and left shoulder pain, weakness of the left hand, myelopathy, and gait imbalance is reported...

BACKGROUND: Complications following locking plate fixation in proximal humeral fractures often related to malposition plates and inadequate screw fixation. However, literature did not define the best anatomical reference point for plate positioning. We conducted a study to assess the occurrence of subacromial impingement and screw perforation with two anatomical reference points for proximal humeral plate positioning. METHOD: Sixty shoulders of 30 cadavers were dissected, and proximal humeral locking plate was placed in two different levels in the coronal plane of the upper tip of plate: (1) the proximal portion of bicipital groove group and (2) the most prominent of lesser tuberosity group...

OBJECTIVES: Although various implants exist for 3- and 4-part proximal humerus fractures, few implants are appropriate for humerus split type greater tuberosity fractures. The goal of this study was to assess the efficacy of pre-contoured anatomic locking plate for humerus split type greater tuberosity fractures. METHODS: A retrospective review of 68 patients with humerus split type greater tuberosity fractures treated with open reduction and internal fixation using anatomic locking plates between January 2014 and October 2016...

REVIEW
Ivan De Martino, Scott A Rodeo
PURPOSE OF REVIEW: Swimmer's shoulder is the term used to describe the problem of shoulder pain in swimmers. Originally described as supraspinatus tendon impingement under the coracoacromial arch, it is now understood that several different pathologies can cause shoulder pain in competitive swimmers, including subacromial impingement syndrome, overuse and subsequent muscle fatigue, scapular dyskinesis, and laxity and instability. RECENT FINDINGS: Swimmers may develop increased shoulder laxity over time due to repetitive use...

Objective: Impingement syndrome is the most common differential in a patient presenting to an orthopaedic OPD with shoulder pain. Impingement syndrome is often managed with subacromial corticosteroid injection, which can be instilled using either landmark guided (LMG) approach or with the assistance of ultrasound (US). This study was envisaged to enquire whether ultrasound assistance improves the accuracy, efficacy or safety profile of the injection. Methods: 60 patients of rotator cuff syndrome underwent diagnostic ultrasound...

BACKGROUND: Literature regarding surfing injuries is scarce and most studies report a high number of minor injuries. Recent literature suggests that musculoskeletal injuries are more common than previously reported. In the mid 2000s, competitive surfing has seen an increase in aerial maneuvers, as they have become more highly rewarded by the judging panel, which may be contributing to a change in injury patterns. Our goal was to evaluate orthopedic injuries in professional surfers. HYPOTHESIS: Orthopedic injuries in professional surfers are diverse and have evolved with skill and technology...

BACKGROUND: Radiographs are used to monitor thoracic kyphosis in individuals with certain pathologies (e.g. osteoporosis), exposing patients to potentially harmful radiation. Thus, other measures for monitoring the progression of thoracic kyphosis are desirable. The gravity-dependent inclinometer has been shown to be reliable but its validity as a measure of thoracic kyphosis has not been investigated. OBJECTIVES: To determine the validity of the gravity-dependent (analogue) inclinometer for measuring thoracic kyphosis...

PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic...

BACKGROUND: The long-term outcome after the treatment of subacromial impingement syndrome (SAIS) with either nonsurgical or surgical methods has not been thoroughly investigated. Hypothesis/Purpose: The purpose was to evaluate the long-term clinical outcome and the presence of rotator cuff injuries and osteoarthritis (OA) after the surgical and nonsurgical treatment of SAIS. The hypothesis was that, at a minimum 10 years after the initial treatment, patients who had undergone acromioplasty would have a better clinical outcome and run a lower risk of developing rotator cuff ruptures and OA as compared with those treated with physical therapy...

Background: Open reduction internal fixation of displaced 3 and 4-part proximal humerus fractures is an effective treatment modality particularly for the younger age group, but it is not without complications. Fixed angled locking screw plates are the mainstay of fixation. The A.L.P.S. Proximal Humerus Plating System is a new implant that has smooth locking pegs in the place of humeral head screws to help reduce glenoid damage in the event of cut-out and is designed to sit low on the humerus in order to reduce the risk of subacromial impingement...

BACKGROUND: In a progredient rotator cuff tear with tendon retraction, fatty infiltration and atrophy of rotator cuff muscles the humerus cannot be centered and stabilized sufficiently in the glenohumeral joint. This leads to rotator cuff defect arthropathy as an eccentric osteoarthritis with acetabularization and wear of the acromion, as well as of the glenoid. INDICATION: A painful pseudoparalysis of the shoulder indicates the implantation of a reversed total shoulder arthroplasty (rTSA) to reduce pain and restore active motion...

BACKGROUND: Subacromial impingement syndrome (SIS) is a painful, and often long lasting, shoulder condition affecting patient function and quality of life. In a recent study, we observed major strength impairments in shoulder external rotation and abduction (~30%) in a population of patients with pronounced and long-lasting SIS. However, the current rehabilitation of such strength impairments may be inadequate, with novel rehabilitation programmes including exercise therapy only improving external rotation strength by 4-13%...

Background: Impaired patient-reported shoulder function and pain, external-rotation strength, abduction strength, and abduction range-of-motion (ROM) is reported in patients with subacromial impingement (SIS). However, it is unknown how much strength and ROM improves in real-life practice settings with current care. Furthermore, outcomes of treatment might depend on specific rehabilitation parameters, such as the time spent on exercises (exercise-time), number of physiotherapy sessions (physio-sessions) and number of corticosteroid injections, respectively...

In 1972, American orthopaedic surgeon Charles Neer published his seminal paper, "Anterior Acromioplasty for the Chronic Impingement Syndrome in the Shoulder: A Preliminary Report." It wasn't a robust scientific paper; however, it changed the direction of orthopaedic practice for the next half century. Neer argued that a primary cause of shoulder pain was attrition of the supraspinatus tendon and related structures from the overlying acromion, especially when the arm was elevated. Neer recommended surgical removal to stop the impingement, and over the last half century, it could be argued that millions of people around the globe would have undergone acromioplasty surgery to stop this portion of the bone impinging onto the soft tissues located in the subacromial space...
