The number of species of Microlepidogaster recently increased considerably, the genus presently comprises six species distributed in the Paraná, São Francisco, and Jequitinhonha river basins. A new species of Microlepidogaster is herein described from the upper Rio São Francisco basin, which can be distinguished from all congeners by having two exclusive features within the genus: skin over swimbladder opening with two to five reduced unperforated platelets, and ventral laminar expansion of coracoid enclosing completely or almost completely the arrector fossa of the pectoral girdle...

INTRODUCTION: The management of displaced fractures of the distal clavicle remains controversial, particularly in younger patients where there is no consensus as to which surgical intervention is best. Each surgical method has unique surgical complications and rates of persistent pain and post-traumatic arthritis. We report an innovative surgical technique using a plate fixation augmented with minimally invasive tension slide coracoclavicular fixation using a cortical tenodesis button (8...

The dugong (Dugong dugon, Müller) is an endangered marine mammal species. We examined the relationship between sex, habitat and body length based on the skull and scapular morphology and morphometrics of 81 dugong samples in Thailand. A total of 58 parameters from the skull and scapula (25 from the cranium, 23 from the mandible and 10 from the scapula) as well as tusks were used in this study. Data were analyzed by univariate analysis, followed by discriminant analysis and multivariate linear regression. Here we show, 100% and 98...

INTRODUCTION: Coracoid fractures are often missed since the fracture is not visualized in a routine anteroposterior view of the shoulder and special views are not ordered. Shoulder dislocation is common but it is rare to have a dislocation with a coracoid fracture. The purpose of this paper is to present the rare occurrence of bilateral coracoid fractures in a patient with unilateral anterior shoulder instability managed using the same fractured coracoid fragment by the latarjet procedure...

Ethnic origin plays an important role in bone morphometry. Studies examining the influence of coracoid process have focused primarily on adults and have not included people from diverse Asian ethnic backgrounds. Our goal was to explore ethnic differences in morphometry of coracoid among Asian population. We performed morphometric measurements of coracoid process on cadaveric shoulders and shoulder CT scans from 118 specimens. The cadaveric sample included Indian (46%), Chinese (27%), and Myanmarese (27%) subjects, while the CT scans sample included Chinese (67%) and Malay (33%) subjects...

There have been no studies investigating three-dimensional (3D) alteration of the coracohumeral distance (CHD) associated with shoulder motion. The aim of this study was to investigate the change of 3D-CHD with the arm in flexion/internal rotation and horizontal adduction. Six intact shoulders of four healthy volunteers were obtained for this study. MRI was taken in four arm positions: with the arm in internal rotation at 0°, 45°, and 90° of flexion, and 90° of flexion with maximum horizontal adduction...

PURPOSE: This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared to the coracoid approach. METHODS: A total of 100 adult patients who received IBPB block for upper limb surgery were randomized into two groups: a coracoid approach group (group C) and a retroclavicular approach group (group R)...

We present an arthroscopic technique for stabilization of chronic acromioclavicular (AC) joint instability using a transclavicular-transcoracoidal button technique, combined with a coracoclavicular and AC ligament reconstruction using the gracilis tendon. This arthroscopic technique achieves an anatomic reduction of the clavicle without further implant removal. It ensures vertical and horizontal stabilization of the AC joint. Using a horizontal drill hole through the clavicle and looping the gracilis tendon graft around the coracoid avoids weakening of the coracoid with the risk of fracture...

Objective: To assess the clinical results of the method of anatomic coracoclavicular ligament reconstruction for distal clavicle fractures. Methods: From August 2013 to January 2015, the super image system was used to measure the CT data of 16 patients suffering distal clavicle fractures before operation in Department of Orthopaedics , the First Affiliated Hospital of Nanjing Medical Univerisity. The fractures' morphological features and acromioclavicular dislocation degree were assessed. By referring to the data collected by the my research group on Chinese people's coracoclavicular ligament, the injuries of the coracoclavicular ligament were estimated, which was then to verify the actual injuries detected during operation...

Acromioclavicular joint injuries are one of the most common shoulder injuries, and there are a variety of treatment options. Recently, there have been newer arthroscopic techniques that have addressed coracoid and clavicle fracture risk by using a knotted suture-button fixation through a single, small bone tunnel with additional looped soft-tissue graft stabilization. Although clinical outcomes have been good to excellent, there have still been instances of knot and hardware irritation. The described technique builds on the latest advances and achieves an anatomic coracoclavicular (CC) reconstruction through a single knotless CC fixation device with additional soft-tissue allograft reconstruction of the CC ligaments...

BACKGROUND: A combined fracture of the glenoid rim, greater tuberosity, and coracoid process after anterior shoulder dislocation is a rare event. Only 1 patient has been reported in the literature. METHODS: All patients with a first-time traumatic anterior shoulder dislocation in a level A trauma center were retrospectively reviewed. Among the 2068 patients treated between 1998 and 2013, we identified 6 patients (0.3%; 1 female, 5 male) with "triple dislocation fracture" (anterior shoulder dislocation with concomitant fracture of the glenoid rim, greater tuberosity, and coracoid process)...

Although the proximal humerus is a common site of osteochondroma, osteochondroma arising from the lesser tuberosity of the proximal humerus is rare. Because of the anatomy of the shoulder, mechanical impingement can occur via direct contact of the protruding lesser tuberosity against the glenoid rim or coracoid. In younger patients, this may cause isolated tearing of the subscapularis. In this study, is presented a rare case of osteochondroma on the lesser tuberosity that caused a subscapularis tear after shoulder impingement in a 34-year-old male...

Knowledge of anatomical variations in the peripheral nervous system is key in the interpretation of unusual clinical signs or during physical or diagnostic imaging. This case study is a description of an anatomical variation between the coracobrachialis muscle and brachial plexus. In a routine dissection in the human anatomy laboratory, we were faced with an anatomical variation in the coracobrachialis muscle, observed in the upper right limb of a male cadaver. The coracobrachialis muscle had a common origin at the apex of the coracoid process and then divided into two heads...

Golfers may injure themselves as a result of repetitive asymmetrical loads exerted on the body by poor swing mechanics. If the repetitive sub-maximal loading is not removed, this repetitive loading will exceed the adaptive capacity of bone, eventually resulting in a stress fracture. Stress fracture of the scapula due to golfing is extremely rare. Only two cases of acromion fracture have been reported. A rare case of nontraumatic coracoid fracture in a 50-year-old female beginner golfer is reported here. The mechanism of injury is also discussed...
