Anatomic variations in course and motor branching pattern of the musculocutaneous nerve with unusual communication with the median nerve were determined on the left arm of a 62-year-old formalin fixed male cadaver. The musculocutaneous nerve did not pierce the coracobrachialis muscle. It provided four primary motor branches. The first branch emerged 1.5 cm inferior to the coracoid process to innervate the coracobrachialis muscle. The second branch emerged 8 cm inferior to the coracoid process to innervate the biceps brachii muscle...

Progress in medical imaging has opened new areas of research in forensic anthropology, especially in the context of the study of bone age assessment. The study of bone age has become a useful tool for age estimation at death or age of young adult migrants in an anthropological context. We retrospectively evaluated multislice computed tomography (MSCT) explorations focused on scapulae of 232 individuals (123 males; 109 females) aged between 8 and 30 years old. Computed tomography (CT) scans were viewed in axial and multiplanar reconstructed images using OsiriX 5...

This study introduced the new delto-fulcral triangle (DFT), the first anatomical model of its kind. As seen from the orthopaedician's supraspinatus-outlet view, the antero-superior point of the coracoid process along with the lateral- and posterior-most acromial landmarks form the boundaries of the DFT. Since these osseous scapular landmarks accounted for both dynamic and static stabilisers of the glenohumeral joint, knowledge of the anatomical features of the DFT may prove beneficial to the orthopaedic surgeon...

The Latarjet procedure involves the transfer of the coracoid process with its soft tissue attachments, thereby providing both bony and soft tissue articular reinforcement for glenohumeral stabilization. Most studies show positive outcomes with this procedure and complications at rates as low as 1%, predominately secondary to technical error. We present a case of recurrent anterior instability after two attempts at soft tissue stabilization (arthroscopic labral repair followed by open inferior capsular shift) in which an open Latarjet procedure was performed followed by subsequent revision secondary to coracoid autograft fracture...

PURPOSE: The purpose of the study was to evaluate the position of the subscapular nerves relative to surgical landmarks during exposure and to analyze the pattern of innervation of the subscapularis to avoid injury during anterior shoulder surgery. METHODS: 20 embalmed human cadaveric shoulder specimens were used in the study. The muscular insertions of the subscapular nerves were marked and their closest branches to the musculotendinous junction and the coracoid process were measured in horizontal and vertical distances...

INTRODUCTION: Clinically, subcoracoid impingement is characterized by pain at the anterior aspect of the shoulder that is induced by adduction, internal rotation and forward flexion. This position leads to narrowing of the Coraco-Humeral Interval (CHI)-that is, the space between the coracoid process and the lesser tuberosity of the humerus. Structures in the rotator interval are at greatest risk for impingement which includes the Subscorapularis tendon, tendon of the long head of the biceps, and the middle gleno-humeral ligament...

BACKGROUND: The Latarjet procedure addresses recurrent anterior shoulder instability in the context of a significant bony defect. However, the bony and soft tissue anatomy of the coracoid in coracoid transfer procedures has not yet been defined in Mongolian men. The aims of this study were to describe the soft tissue attachments of the coracoid regarding the bony anatomy, define the average amount of bone available for coracoid transfer, analyze the characteristics of the pectoralis minor and coracoid, and study the relationship between the bony dimensions of the coracoid and body length in Mongolian men...

BACKGROUND: The Latarjet-Patte procedure consisting in transfer and screw fixation of the coracoid process to the anterior glenoid is a treatment of reference for anterior shoulder instability. Over time, surgical innovations translated into a number of improvements and, in late 2003, an arthroscopically assisted variant of the procedure was described. OBJECTIVE: To evaluate and compare clinical outcomes of the modified Latarjet-Patte procedure performed by open surgery, arthroscopy with screw fixation, or arthroscopy with endobutton fixation...

A new fossil salamander, Nuominerpeton aquilonaris (gen. et sp. nov.), is named and described based on specimens from the Lower Cretaceous Guanghua Formation of Inner Mongolia, China. The new discovery documents a far northern occurrence of Early Cretaceous salamanders in China, extending the geographic distribution for the Mesozoic fossil record of the group from the Jehol area (40th-45th parallel north) to near the 49th parallel north. The new salamander is characterized by having the orbitosphenoid semicircular in shape; coracoid plate of the scapulocoracoid greatly expanded with a convex ventral and posterior border; ossification of two centralia in carpus and tarsus; and first digit being about half the length of the second digit in both manus and pes...

The aim of our study is to evaluate the clinical and radiologic outcomes in patients with terrible triad injury, who underwent surgical treatment with or without the medial collateral ligament (MCL) repair. Fourteen patients who underwent surgery with a minimum of 12-month follow-up (mean, 17 months) were reviewed. Based on the systematic treatment protocol, radial head fracture, lateral collateral ligament, and coracoid fracture were treated. Subsequently, torn MCL was repaired in 7 patients, whereas in the remaining 7 patients, the MCL was not treated...

: The subscapularis (SSC) muscle is the most powerful of the rotator cuff muscles, and plays an important role in shoulder motion and stabilization. SSC tendon tear is quite uncommon, compared to the supraspinatus (SSP) tendon, and, most of the time, part of a large rupture of the rotator cuff. Various complementary imaging techniques can be used to obtain an accurate diagnosis of SSC tendon lesions, as well as their extension and muscular impact. Pre-operative diagnosis by imaging is a key issue, since a lesion of the SSC tendon impacts on treatment, surgical approach, and post-operative functional prognosis of rotator cuff injuries...

PURPOSE: The arthroscopic Latarjet procedure has provided reliable results in the treatment of anterior shoulder instability. However, this procedure remains technically challenging and is related to several complications. The morphology of the coracoid and the glenoid are inconsistent. Inadequate coracoid and glenoid preparing may lead to mismatching between their surfaces. Inadequate screws lengthening and orientation are a major concern. Too long screws can lead to suprascapular nerve injuries or hardware irritation, whereas too short screws can lead to nonunions, fibrous unions or migration of the bone block...

BACKGROUND AND HYPOTHESIS: The Latarjet procedure has been shown to be a reliable method to prevent recurrent anterior shoulder instability. Coracoid bone graft osteolysis is a potential catastrophic complication and can lead to recurrent instability. The purpose of our study is to present a novel quantitative method to measure the amount of coracoid bone osteolysis using 3-dimensional (3D) computed tomography (CT) scan imaging. MATERIALS AND METHODS: This is a prospective study with 15 patients (16 shoulders) who underwent an arthroscopic Latarjet procedure...

Increased physical activity in childhood has resulted in a large number of sports-related injuries. Although there is overlap between the sports-related injuries seen in pediatric and adult patients, important differences exist in the injury patterns of pediatric patients. These differences are related to the continuous changes in the developing skeleton and its relationship with adjacent soft tissues. The imbalance in strength between the growing bones and the nearby tendons and ligaments makes the bones prone to acute and chronic injuries...
