Summary of "Humeral head fracture and cuff."

During the past decade the evaluation of the rotator cuff in the management of proximal humeral fractures has received increasing attention. Different studies have investigated the pathomorphology, prevalence and impact of rotator cuff lesions on the outcome of non-operative or surgical treatment of proximal humeral fractures. Tendon defects, either chronic or trauma related, are observed mainly in the anterosuperior or posterosuperior aspect of the rotator cuff and present as partial- or full-thickness tears. Structural changes of the rotator cuff muscles including atrophy and fatty infiltration in the context of proximal humeral fractures have been inadequately investigated. The prevalence of coexisting rotator cuff pathology varies between 5 and greater than 50% depending on the method of evaluation, the fracture morphology and the age of the patient. The influence of a concomitant rotator cuff tear on the clinical outcome has not been conclusively investigated. However, different studies indicate that some lesions can be a source of persistent pain and functional deficit after conservative or surgical management of proximal humeral fractures. Therefore, a simultaneous repair of the rotator cuff defect during surgical reconstruction of the proximal humerus is indicated.

Unusual humeral medial condyle fracture in an adolescent because of a previous post-traumatic fishtail deformity: a case report.

A fishtail deformity is a well-known complication following pediatric lateral condyle fracture of the humerus. We report a rare case of a medial humeral condyle fracture in a 12-year-old boy who had h...

Complex proximal humerus fractures: Hertel's criteria reliability to predict head necrosis.

The risk of post-traumatic humeral head avascular necrosis (AVN), regardless of the treatment, has a high reported incidence. In 2004, Hertel et al. stated that the most relevant predictors of ischemi...

The isolated medial humeral epicondyle fracture treated nonoperatively: does fracture displacement change over time?

This study explores the change in the position of the fragment in isolated, displaced, medial humeral epicondyle fractures in children. In this series, 34 patients (mean age 11.0 years) were treated n...

Glenoid damage from articular protrusion of metal suture anchor after arthroscopic rotator cuff repair.

Arthroscopic repair of rotator cuff tears has been shown to be effective and safe. The use of suture anchors has increased the ability to perform rotator cuff repairs arthroscopically. However, the us...

Multivariate Analyses of Rotator Cuff Pathologies in Shoulder Disability.

Disability of the shoulder joint is often caused by a tear in the rotator cuff (RC) muscles. Four RC muscles coordinate shoulder movement and stability, among them the supraspinatus and infraspinatus ...

Medical and Biotech [MESH] Definitions

Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom. (From Jablonski's Dictionary of Syndromes and Eponymic Diseases, 2d ed)

Fracture in the proximal half of the shaft of the ulna, with dislocation of the head of the radius.

The portion of the upper rounded extremity fitting into the glenoid cavity of the SCAPULA. (from Stedman, 27th ed)

Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.
