BACKGROUND Clinicians frequently rely on subjective categorization of impairments in mobility, strength, and endurance for clinical decision-making; however, these assessments are often unreliable and lack sensitivity to change. The objective of this study was to determine the inter-rater reliability, minimum detectable change (MDC), and group differences in quantitative cervicothoracic measure...

Patients with high-grade sarcomas arising from the scapula or periscapular soft tissues traditionally have been treated with either a total scapulectomy or a wide, en bloc, extraarticular scapular resection, termed the Tikhoff-Linberg resection. The major challenge after such resections is to restore shoulder girdle stability while preserving a functional hand and elbow. The current authors des...

BACKGROUND There have been few reports on altered kinematics of the shoulder after reverse total shoulder arthroplasty (RTSA). We investigated differences in 3-dimensional (3D) scapular motions assessed using an optical tracking system between RTSA treated shoulders and asymptomatic contralateral shoulders during arm motion. METHODS Thirteen patients who underwent RTSA were assessed for activ...

PURPOSE To report outcomes of 21 men who underwent stabilisation for the disrupted acromioclavicular joint (ACJ) using a braided polyester prosthetic ligament. METHODS 21 men aged 23 to 76 (mean, 43) years underwent stabilisation for the disrupted ACJ of Rockwood type 3 (n=12), type 4 (n=1), and type 5 (n=8) using a braided polyester prosthetic ligament. RESULTS The mean time from injury to...

BACKGROUND Following shoulder arthroplasty, any well-planned rehabilitation program should include muscle strengthening. However, it is not always clear how different external loads influence shoulder kinematics in patients with shoulder prostheses. The objective of this study was to describe shoulder kinematics and determine the contribution of the scapulothoracic joint to total shoulder motio...

The biomechanical changes due to increased arm mass in individuals with high body mass index (BMI) may lead to altered scapular motions at the shoulder joint. Scapula kinematic alterations are often associated with shoulder pain and pathology, and if present in overweight or obese individuals could impact shoulder health. The purpose of this study was to examine if scapula biomechanics differ b...

We report the results of fifteen cases of Sprengel's deformity treated surgically by initial subperiosteal resection of the middle third of the clavicle in conjunction with surgical release of all attachments of the scapula to the spine, excision of any omovertebral bone and resection of prominent supraspinous process of scapula. The patients included ten female and three male patients (age ran...

We report a 38-year-old man with a combination of fractures in his left shoulder involving the middle and distal clavicle, the scapular neck, and the coracoid process, associated with scapulothoracic dissociation and an upper brachial plexus injury. The middle clavicular fracture was fixed with a plate, whereas the distal clavicular fracture was fixed with tension band wiring. Internal fixation...

Abnormal scapulothoracic mechanics and scapulohumeral rhythm are implicated in shoulder pathologies, including glenohumeral impingement and rotator cuff tears. Upward scapula rotation, specifically asymmetry of scapula motion and associations of patterns through range with injury, was investigated in dominant and non-dominant limbs of nationally ranked junior and Paralympic swimmers during comp...
