The triceps brachii muscle occupies the posterior compartment of the arm in humans and has three heads. The lateral and medial heads originate from the humerus and the long head arises from the infraglenoid tubercle of the scapula. All heads form a common tendon that inserts onto the olecranon and the deep antebrachial fascia on each side of it. Each head receives its own motor branch, which all are thought to originate from the radial nerve. However, several studies reported that the motor branch of the long head of the triceps (LHT) arises from the axillary nerve or the posterior cord...

REVIEW
Charalampos G Zalavras, Efthymios Papasoulis
Intra-articular fractures of the distal humerus are complex injuries that can considerably limit elbow function if not treated appropriately. Surgical management is indicated for most intra-articular distal humerus fractures with the goal of restoring elbow range of motion and function. Open reduction and internal fixation (ORIF) with plates and screws has been the preferred surgical option. Double plating is recommended for bicolumnar fractures and plates can be applied either parallel or orthogonal to each other...

OBJECTIVE: To assess whether "center-center" position is ideal starting point for minimum fracture displacement when placing an intramedullary screw in the ulna. METHODS: Thirty-six arms (average age, 82 years) underwent a posterior approach to the olecranon and were randomized into 3 groups: center-center (center in sagittal plane, center in coronal plane), posterior-lateral (posterior in sagittal plane, lateral in coronal plane), posterior-medial (posterior in sagittal plane, medial in coronal plane)...

BACKGROUND: The medial triceps brachii is vascularized by the middle collateral artery and the arterial circle of the elbow. This vascularization allows a distal pedicled use to cover soft tissue defects of the elbow. We report our experience using this flap to cover traumatic and postsurgical wounds. METHODS: Patients who underwent a pedicled medial triceps brachii flap procedure between 2008 and 2015 were included. Data concerning characteristics of the patients, wound size, surgical technique, and complications were retrospectively reviewed...

BACKGROUND: It is important to estimate the likelihood that a pediatric fracture is caused by osteogenesis imperfecta (OI), especially the least severe type of OI (type 1). METHODS: We reviewed records of 29,101 pediatric patients with fractures from 2003 through 2015. We included patients with closed fractures not resulting from motor vehicle accidents, gunshot wounds, nonaccidental trauma, or bone lesions. Patients with OI of any type were identified through International Classification of Diseases-9 code...

BACKGROUND: Small olecranon fractures present a significant challenge for fixation, which has resulted in development of plates with proximal extension. Olecranon-specific plates with proximal extensions are widely thought to offer superior fixation of small proximal fragments but have distinct disadvantages: larger dissection, increased hardware prominence, and the increased possibility of impingement. Previous biomechanical studies of olecranon fracture fixation have compared methods of fracture fixation, but to date there have been no studies defining olecranon plate fixation strength for standard versus extended olecranon plates...

EDITORIAL
Shawn W O'Driscoll
Posterior impingement pain in baseball players is typically due to a fractured olecranon osteophyte. Computed tomographic (CT) scanning is the imaging of choice when evaluating posterior or posteromedial elbow pain in athletes who have subjected the elbow to excessive stresses such as occur in overhead throwing and weightlifting. Sometimes the fracture fragment can be so small that it might not be detected on plain radiographs, magnetic resonance imaging, or even at the time of arthroscopy. Symptomatic fractured olecranon osteophytes can be diagnosed clinically with the extension impingement test or arm bar test...

INTRODUCTION: Surgery is the gold-standard treatment of displaced olecranon fracture, but is associated with numerous complications, especially in the elderly. Functional results of non-operative treatment in this population have never been analyzed in a prospective study. STUDY HYPOTHESIS: Non-operative treatment of isolated olecranon fracture with stable elbow-joint in over 75-year-olds gives functional results comparable to those of surgery as reported in the literature, with fewer complications...

Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food, and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed...
