A humerus fracture is a break of the humerus bone in the upper arm. [1] Symptoms may include pain, swelling, and bruising . [ 1 ] There may be a decreased ability to move the arm and the person may present holding their elbow. [ 2 ]
Comminuted midshaft humerus fracture with callus formation. A fibrocartilage callus is a temporary formation of fibroblasts and chondroblasts which forms at the area of a bone fracture as the bone attempts to heal itself. The cells eventually dissipate and become dormant, lying in the resulting extracellular matrix that is the new bone. The ...
Gustilo Open Fracture Classification (Medical Science) Gustilo Grade Definition I: Open fracture, clean wound, wound <1 cm in length II: Open fracture, wound > 1 cm but < 10 cm in length [4] without extensive soft-tissue damage, flaps, avulsions
The radial nerve follows the humerus closely. At the midshaft of the humerus, the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. A fracture of the humerus in this region can result in radial nerve injury. The ulnar nerve lies at the distal end of the humerus near the elbow. When struck, it can ...

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 ...
Diagram of an open, transverse, midshaft radius fracture. Cephalosporins, sometimes with aminoglycosides, are generally the first line of antibiotics and are used usually for at least three days. [3] Therapeutic irrigation, wound debridement, early wound closure and bone fixation core principles in management of open fractures. [4]
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 ...
