OBJECTIVE: Scapular stabilization exercises (SSE) are well-established for the able-bodies. The aim of the current study is to access the potential benefits of SSE on isometric internal and external rotator strength, endurance and function of the shoulder in persons with tetraplegia, throughout a 12-week exercise program consisting of five resisted movements with elastic bands. DESIGN: Prospective non-controlled intervention study. Setting/Participants/Interventions: A convenience sample of 17 subjects (age, 40...

BACKGROUND: Cervical dystonia, commonly referred to as spasmodic torticollis, is a neurological disorder characterized by aberrant, involuntary contraction of the muscles of the neck and shoulders. One surgical option that can be considered is selective cervical denervation. OBJECTIVE: To report our modification of the Bertrand procedure for selective cervical denervation. METHODS: Our modification of the Bertrand procedure for selective cervical denervation is reported with intraoperative photographs and schematic depictions of the operative steps...

PURPOSE: To analyze the effect of lack of standardization on the reliability of current measurement techniques for glenoid bone loss in clinical practice. METHODS: Ten consecutive patients with anterior glenoid bone loss due to recurrent anterior shoulder instability and available computed tomographic (CT) scans of the affected shoulder were included in this study. One hundred seventy 3-dimensional en-face view images of the 10 glenoids with up to 20° degrees of tilt in the anterior, posterior, superior, and inferior direction were rendered...

Correct anatomical alignment of the glenoid component is of central importance for wear and loosening in shoulder endoprostheses. The aim of this article is to review and clarify the biomechanical and clinical effects of incorrect glenoid inclination in reverse and anatomical joint replacements. Based on the literature and on our own work, statements are made about the following: (1) the glenoid inclination of a normal glenoid, a degenerative glenoid and a glenoid implant, and the consequences if superior inclination is too large, and (2) the surgical technique as well as tips and tricks for correct adjustment of the inclination...

To verify the applicability of a new approach based on the strength curves (SCs) methodology in late arm impairment in breast cancer (BC) survivors and to evaluate the effects of dragon boat (DB) activity on the late regaining of the muscle strength, upper limb impairment, and quality of life in patients undergoing surgery for BC.Retrospective observational study on 64 subjects (54.5 ± 9.7 years), 47 of them had undergone unilateral mastectomy surgery and were evaluated for late arm impairment. A clinical evaluation of the shoulder and compilation of functional assessment (DASH, Rowe, Constant-Murley) and quality of life (SF-36) scales were carried out...

OBJECTIVE To determine variance effects influencing ground reaction forces (GRFs) in a heterogeneous population of lame dogs during trotting. ANIMALS 30 client-owned dogs with thoracic limb lameness and 31 dogs with pelvic limb lameness. PROCEDURES GRFs, velocity, height at the dorsal aspect of the scapulae (ie, withers), and shoulder height were obtained. Each dog was trotted across a force platform at its preferred velocity. Variance effects for 12 velocity and associated relative velocity (V*) ranges were examined...

Subject-specific musculoskeletal models can predict accurate joint and muscle biomechanics thereby helping clinicians and surgeons. Current modeling strategies do not incorporate accurate subject-specific muscle parameters. This study reports a statistical shape model (SSM) based method to predict subject-specific muscle attachment regions on shoulder bones and illustrates the concurrent validity of the predictions. Augmented SSMs of scapula and humerus bones were built using bone meshes and five muscle attachment (origin/insertion) regions which play important role in the shoulder motion and function...

Upper limb three-dimensional movement analysis (UL-3DMA) offers a reliable and valid tool to evaluate movement patterns in children with unilateral cerebral palsy (uCP). However, it remains unknown to what extent the underlying motor impairments explain deviant movement patterns. Such understanding is key to develop efficient rehabilitation programs. Although UL-3DMA has been shown to be a useful tool to assess movement patterns, it results in a multitude of data, challenging the clinical interpretation and consequently its implementation...

BACKGROUND: Description of the native shape of a glenoid helps surgeons to preoperatively plan the position of a shoulder implant. A statistical shape model (SSM) can be used to virtually reconstruct a glenoid bone defect and to predict the inclination, version, and center position of the native glenoid. An SSM-based reconstruction method has already been developed for acetabular bone reconstruction. The goal of this study was to evaluate the SSM-based method for the reconstruction of glenoid bone defects and the prediction of native anatomic parameters...

OBJECTIVES: Pygathrix is an understudied Asian colobine unusual among the Old World monkeys for its use of arm-swinging. Little data exists on the anatomy and mechanics of brachiation in this genus. Here, we consider this colobine to gain insight into the parallel evolution of suspensory behavior in primates. MATERIALS AND METHODS: This study compares axial and appendicular morphological variables of Pygathrix with other Asian colobines. Additionally, to assess the functional consequences of Pygathrix limb anatomy, kinematic and kinetic data during arm-swinging are included to compare the douc monkey to other suspensory primates (Ateles and Hylobates)...

BACKGROUND: The global range of motion of the arm is the result of a coordinated motion of the shoulder complex including glenohumeral (GH), scapulothoracic, sternoclavicular and acromioclavicular joints. METHODS: This study is a non-systematic review of kinematic patterns in degenerated shoulders. It is a based on our own research on the kinematics of the shoulder complex and clinical experience. RESULTS: For patients with subacromial impingement syndrome without rotator-cuff tears, most kinematic studies showed a small superior humeral translation relative to the glenoid and decreased scapular lateral rotation and posterior tilt...

BACKGROUND: How the shape of the glenoid defect being reconstructed influences stability in reversed shoulder arthroplasty has never been evaluated. The purpose of this study was to compare the reconstruction of two different shaped defects in reversed shoulder arthroplasty. METHODS: Two groups (ten Sawbone scapulae each) of oblique- and rectangular-shaped glenoid defects were tested biomechanically. On the anterior half of the glenoid, bony defects (rectangular and oblique shaped) were prepared and reconstructed subsequently with a graft and reversed shoulder arthroplasty...

BACKGROUND: Several etiologic factors have been postulated in overhead athletes according to their shoulder injuries, such as the scapular posture asymmetries. The measurement of the acromion border distance has been considered as reliable clinical test for evaluating the static scapula posture. The aim of this study was to quantify the differences in scapular posture between the dominant and non-dominant shoulders in two static positions in volleyball and swimmers athletes with asymptomatic shoulder injuries using the sliding calliper device...

BACKGROUND: Sprengel deformity is a rare congenital shoulder girdle anomaly characterized by scapula malposition, periscapular muscle atrophy, and limited shoulder movement. Traditionally, it has been managed by omovertebral bar excision and muscle transplantation procedures guided by age and Cavendish grade. We present a unique observation in humans: a case series with Sprengel deformity possessing a cleithrum, an ancestral remnant of shoulder girdle development found in archaic bony fish...

BACKGROUND: Version correction via eccentric reaming reduces clinically important retroversion in Walch type B2 glenoids (those with substantial glenoid retroversion and a second, sclerotic neoglenoid cavity) before total shoulder arthroplasty (TSA). Clinically, an increased risk of glenoid component loosening in B2 glenoids was hypothesized to be the result of compromised glenoid bone quality attributable to eccentric reaming. However, no established guidelines exist regarding how much version correction can be applied without compromising the quality of glenoid bone...
