BACKGROUND: Coplaning means the removal of medial acromial spurs and inferior aspect of the distal clavicle. The aim of the study was to evaluate the outcomes of arthroscopic acromioplasty with and without coplaning in patients without acromioclavicular (AC) joint arthritis. METHODS: Because of impingement syndrome, arthroscopic subacromial decompression and acromioplasty was performed in Group 1 (9 males/31 female). In addition, coplaning was performed in Group 2 (8 males/21 females) by two different surgeons...

Objective: To correlate the acromiohumeral distance (AHD) using tomosynthesis and rotator cuff (RC) pathology and various anatomical indices and to assess the diagnostic reproducibility of tomosynthesis for the evaluation of subacromial impingement. Materials and Methods: A retrospective review of 63 patients with clinically suspected subacromial impingement was conducted. Two musculoskeletal radiologists independently measured the following quantitative data: the AHD on plain radiographs and the AHD at three compartments (anterior, middle, and posterior) using tomosynthesis, computed tomography (CT) arthrography, or magnetic resonance (MR) arthrography...

BACKGROUND: Comorbidities within the breast cancer population can reduce quality of life. Current breast cancer survivor upper limb kinematic strategies unfortunately lack robust connection with performing important activities of daily living. METHODS: Accordingly, fifty breast cancer survivors performed 88 dynamic tasks (divided into range of motion-reach, range of motion-rotate, activity of daily living, and work tasks). Humerothoracic and scapulothoracic angles were extracted from motion capture data...

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...

Subacromial impingement of the rotator cuff is understood as a contributing factor in the development of rotator cuff tendinopathy. However, changes that occur in the impinged tendon are poorly understood and warrant further study. To enable further study of rotator cuff tendinopathy, we performed a controlled laboratory study to determine feasibility and baseline characteristics of a new murine model for subacromial impingement. This model involves surgically inserting a microvascular clip into the subacromial space in adult C57Bl/6 mice...

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...

Proximal humerus fractures constitute a significant percentage of fragility fractures. The growing use of locking plate has helped treat this problem, but at the same time has brought about complications. Past systematic reviews have documented these complications, however a large number of recent studies have been published since, reporting their own complication rates with different techniques. This study reviews the current complications associated with locking plate of proximal humerus fractures as well as methods to reduce them...

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...

Rotator cuff disease affects a large proportion of the overall population and encompasses a wide spectrum of pathologies, including subacromial impingement, rotator cuff tendinopathy or tear, and calcific tendinitis. Various injection therapies have been used for the treatment of rotator cuff disease, including corticosteroid, prolotherapy, platelet-rich plasma, stem cells, and ultrasound-guided barbotage for calcific tendinitis. However, the existing evidence for these therapies remains controversial or sparse...

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...

Medial scapular winging is often due to dysfunction of the serratus anterior muscle as a result of injury to the long thoracic nerve. Impairment of the serratus anterior muscle may cause uncoordinated scapulohumeral rhythm during shoulder elevation and subsequent subscapular or shoulder pain, subacromial impingement, and glenohumeral joint instability. Although long thoracic nerve injury typically resolves in 12 to 18 months after a physical therapy regimen, surgical intervention is indicated in patients who fail conservative management...

OBJECTIVES: The aim of this study was to analyse the effect of subscapularis tear on superior humeral excursion (SHE) and acromiohumeral distance (AHD). The hypothesis was that subscapularis tears do not result in superior humeral excursion. METHODS: Patients who underwent shoulder arthroscopy between August of 2011 and 2015 were reevaluated. Those with isolated Bankart lesion were used as control group and included in the Group 1, isolated full-thickness supraspinatus tear in the Group 2, isolated subscapularis tear in the Group 3, and combined subscapularis and supraspinatus tear in the Group 4...
