It is vulnerable to injury with fractures of the humeral shaft as it lies in very close proximity to the bone (it descends within the spiral groove on the posterior aspect of the humerus). Characteristic findings following injury will be as a result of radial nerve palsy (e.g. weakness of wrist/finger extension and sensory loss over the dorsum ...
The cause of a humerus fracture is usually physical trauma such as a fall. [1] Other causes include conditions such as cancer in the bone. [2] Types include proximal humeral fractures, humeral shaft fractures, and distal humeral fractures. [1] [2] Diagnosis is generally confirmed by X-rays. [2]
The distal humerus grows slowly post fracture (only contributes 10 to 20% of the longitudinal growth of the humerus), therefore, there is a high rate of malunion if the supracondylar fracture is not corrected appropriately. Such malunion can result in cubitus varus deformity. [citation needed]
A proximal humerus fracture is a break of the upper part of the bone of the arm . [3] Symptoms include pain, swelling, and a decreased ability to move the shoulder . [ 1 ] Complications may include axillary nerve or axillary artery injury.
The native humerus and scapula bones are prepared using precise machining to accommodate their respective implants. At the end of the procedure, the subscapularis muscle is typically repaired, although some surgeons advocate not repairing this muscle due to the excess tension placed on it by the altered mechanics of the reverse shoulder design.
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
Medial epicondyle fractures account for 10% elbow fractures in children. 25% of injuries are associated with a dislocation of the elbow. Medial epicondyle fractures are typically seen in children and usually occur as a result of a fall onto an out-stretched hand. This often happen from falls from a scooter, roller skates, or monkey bars, as ...
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
