Background: Generalized joint hyper mobility predisposes some individuals to a wide variety of musculoskeletal complaints. Given the critical role of scapular position in function of shoulder, the aim of this study was to compare scapular position between persons with and without general joint hyper mobility. Methods: By nonprobability sampling 30 hyper mobile persons at average of 22.86 ±2.77...

The complexity of shoulder mechanics combined with the movement of skin relative to the scapula makes it difficult to measure shoulder kinematics with sufficient accuracy to distinguish between symptomatic and asymptomatic individuals. Multibody skeletal models can improve motion capture accuracy by reducing the space of possible joint movements, and models are used widely to improve measuremen...

STUDY DESIGN Controlled laboratory study. OBJECTIVES To measure superior/inferior translation and external rotation of the humerus relative to the scapula during scapular plane abduction using 3-D/2-D model image registration techniques. BACKGROUND Kinematic changes in the glenohumeral joint, including excessive superior translation of the humeral head and inadequate external rotation of th...

Introduction Rotator cuff tears are common conditions that often require surgical repair to improve function and relieve pain. Unfortunately, despite pain relief, the success associated with repair integrity is mixed, with 5-95% of patients having recurrent tears, resulting in decreased strength and function. Several factors may contribute to repair failure including age, tear size, and time fr...

Sex determination from skeletal human remains by discriminant function analysis is one of the methods utilized in the forensic and osteoarcheological sciences. The purpose of the present study is to establish metric standards for sex determination for medieval Anatolian populations using scapular measurements. The database for this research consisted of 93 adult skeletal remains (47 males and 4...

OBJECTIVE This clinical study investigated the effects of an individually fabricated prone positioner on heart rate, respiratory rate, and scapular position of premature infants in the neonatal intensive care unit. The prone positioner consisted of dense foam with cutouts to position the shoulders forward and toward midline. METHOD Six measurements of scapular rotation, respiratory rate, hear...

Scapular kinematics have been previously studied in adults and healthy children (1,2) and differences have been observed between adults and children (1). Brachial Plexus Birth Palsy (BPBP) often affects the shoulder musculature and these children display impairments in humeral elevation in the affected limb, glenohumeral (gh) joint deformities and compensatory changes in scapulothoracic (st) mo...

We report a case of a stress fracture of the scapular spine which developed as a late complication of a reverse shoulder arthroplasty. After initially doing well after surgery, our patient developed pain and decreased shoulder function. A nondisplaced scapular spine fracture was noted on radiographs. Because reverse shoulder arthroplasty is a relatively new procedure in this country, radiologis...

BACKGROUND The aim of the study was to investigate the feasibility of fluoroscopy-guided anterior approach for suprascapular nerve block (SSNB). METHODS Twenty patients with chronic shoulder pain were included in the study. All of the nerve blocks were performed with patients in a supine position. Fluoroscopy was tilted medially to obtain the best view of the scapular notch (medial angle) and...

OBJECTIVES In this study, the hypothesis that tennis players with scapular dyskinesia present a smaller subacromial space than non-athletes was investigated. Additionally, the correlation between the size of the subacromial space and abnormalities in scapular movement during arm abduction was studied. DESIGN Cross-sectional study. PARTICIPANTS A total of 53 elite tennis players and 20 contr...
