Injuries to the ulnar collateral ligament frequently occur in throwing athletes because of large, repetitive valgus stresses to the elbow during the cocking and acceleration phases of throwing. Identification of injury to this ligament is important in evaluating the throwing elbow. The purpose of this study was to determine whether differences in medial elbow laxity exist between the dominant a...

The objective of the present study was to examine whether the passive range of shoulder external rotation (ER), the maximum shoulder external rotation angle (MER) during throwing, and the ratio of MER to ER are related to the incidence of the elbow injury. A mixed design with one between-factor (a history of the elbow injury) and two within-factors (ER and MER) was used to analyze the differenc...

BACKGROUND Loss of elbow flexion due to traumatic palsy of the brachial plexus represents a major functional handicap.Then, the first goal in the treatment of the flail arm is to restore the elbow flexion by primary direct nerve surgery or secondary reconstructive surgery. There are various methods to restore elbow flexion which are well documented in the medical literature but the most known a...

An analysis of arm movements involving forward projection of the hand in order to reach for and grasp a target at different orientations is presented. The reaching movements required shoulder flexion, elbow extension, and wrist pronation or supination. The relation between elbow and shoulder instantaneous angular position proved to be consistent from trial to trial of each task, independent of ...

The activity of motor cortical cells and proximal arm muscles during the initiation of planar reaching movements were analyzed to identify whether features of coordinated motor patterns of muscles spanning the elbow and shoulder were evident in the discharge patterns of motor cortical cells. Shoulder and elbow muscles were divided into four groups, flexors and extensors at each joint. Features ...

In patients with an elbow fracture dislocation the incidence of radial head fracture is 36%, where as coronoid process fractures occur in 13%, and olecranon fractures in 4% of patients. Combination of all these fractures with a 'terrible triad' is rarely reported in the literature. We describe a 40 year old lady involved in a polytrauma who had head injury, pnuemothorax and an open fracture dis...

Open arthrolysis is an effective way to treat elbow stiffness. However, previous approaches led to significant surgical trauma. The goal of the current study was to evaluate the outcome of open arthrolysis with limited medial and lateral approaches combined with hinged external fixation to treat elbow stiffness. A total of 18 patients (18 elbows) with elbow stiffness were retrospectively review...

INTRODUCTION Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient's self-evaluation after the excision of the heterotopic ossification. MATERIALS ...

In cubarthritis-osteoarthritis of the elbow-surgical procedures may be considered to debride the elbow joint to reduce pain, to increase mobility, and to postpone joint replacement surgery. The ulnohumeral arthroplasty as described by Outerbridge and Kashiwagi was originally introduced to debride both anterior and posterior elbow compartments through a direct posterior mini-open approach. To ac...

The elbow joint needs to be both mobile and stable to exercise its hinge function, which is the key to a normal upper limb. Loss of motion in the elbow joint leads to an exponential functional handicap. Elbow trauma is a common cause of elbow stiffness. Open elbow arthrolysis with release of the capsule has been demonstrated to be a very useful treatment. Arthroscopic elbow arthrolysis has now ...
