The effect of rotator cuff tears on reaction forces at the glenohumeral joint.

The rotator cuff muscles maintain glenohumeral stability by compressing the humeral head into the glenoid. Disruption of the rotator cuff compromises concavity compression and can directly affect the loads on the glenohumeral joint. The purpose of this study was to quantify the effect of rotator cuff tears on the magnitude and direction of glenohumeral joint reaction forces during active shoulder abduction in the scapular plane using nine cadaveric upper extremities. Motion of the full upper extremity was simulated using a dynamic shoulder testing apparatus. Glenohumeral joint reaction forces …

A Clinical Comparison of Linear- and Surface Area-Based Methods of Measuring Glenoid Bone Loss.

BACKGROUND: The purpose of this study was to determine whether linear-based measurement significantly overestimates glenoid bone loss in com … bilateral shoulder computed tomography (CT) scans. Three-dimensional CT (3D-CT) reconstruction with humeral head subtraction was performed to obtain an en face view of the 3D-CT glenoid. Glenoid bone loss was measured with the surface area and linear methods of measurement. Statistical analysis was performed with a paired 2-tailed t test. RESULTS: Twenty-eigh …

Latarjet reconstruction in patients with anterior shoulder instability and significant Hill-Sachs lesion.

Management of glenohumeral instability with large Hill-Sachs lesions remains controversial either to address or just grafting the glenoid rim defects. This study was done to investigate if open Latarjet is sufficient to prevent recurrent instability in patients with significant Hill-Sachs defects without addressing these lesions. In the period between October 2009 and November 2014 twenty three patients with shoulder instability and significant bone loss were treated by open Latarjet. All patients were followed up for a period ranged from 17 to 58 months (median ± SD : 30 ± 13.9).The mean preo

Subscapularis Tendon Slip Number and Coracoid Overlap Are More Related Parameters for Subcoracoid Impingement in Subscapularis Tears: A Magnetic Resonance Imaging Comparison Study.

PURPOSE: To investigate the effects of the subscapularis tendon slip number (STSN) and coracoid morphology by magnetic resonance imaging in patients with and without subscapularis tears. METHODS: Patients who underwent shoulder arthroscopy between February 2004 and June 2015 were re-evaluated. Those with a subscapularis tear (study group) and those with other pathologies (control group) were compared with each other. Magnetic resonance imaging scans and surgery videos of the patients were reassessed. Transverse and sagittal coracohumeral distance (CHD), coracoid overlap (CO), coraco-coracoid

Charcot Arthropaticy of the Peelter with Ipsionteral Wrist и First Carpometakarpal Shiri Malformation I Type with Syringomyelia.

Артропатия плеча является редким проявлением нервно - суставной болезни и чаще всего ассоциируется с шприцомелией. Когда это происходит, оно часто приводит к постепенному совместному разрушению, но из-за минимальной боли оно приводит к задержкам в диагностике. Мы сообщаем о случае 54-летней женщины, представлявшей трехмесячную историю опухоли левого плеча, деформации и жесткого ограничения диапазона движения, связанного с ипсиосторонней деформацией запястья. У пациента была известная история неправильной формы Кьяри первого типа с шприцомелией. В ходе клинического обследования была выявлена за

Anatomical Study of the Ventral Upper Arm Muscles with a Case Report of the Accessory Coracobrachialis Muscle.

Background and Objectives: The muscles in the upper arm are categorized into two groups: ventral muscles, which include the biceps brachii, coracobrachialis, and brachialis, and dorsal muscles comprising the triceps brachii and anconeus. These muscles are positioned in a way that they contribute to movements at the shoulder and elbow joints. Given the importance of the upper arm muscles for various reasons, they need to be well-known by medical professionals. Ventral upper arm muscles exhibit various topographical and morphological variations. Understanding these variations is critical from bo

Controversies In The Surgical Management Of Shoulder Instability: Associated Soft Tissue Procedures.

BACKGROUND: The glenohumeral joint is a ball-and-socket joint that is inherently unstable and thus, susceptible to dislocation. The traditional and most common anatomic finding is the Bankart lesion (anterior-inferior capsule labral complex avulsion), but there is a wide variety of anatomic alterations that can cause shoulder instability or may be present as a concomitant injury or in combination, including bone loss (glenoid or humeral head), complex capsule-labral tears, rotator cuff tears, Kim´s lesions (injuries to the posterior-inferior labrum) and rotator interval pathology. METHODS: A …
