Specialty: Orthopedics: Symptoms: Joint pain, decreased ability to move [1] Complications: Osteoarthritis [1] Usual onset: Gradual [1] Risk factors: Bone fractures, joint dislocations, high dose ...
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 ...
ICD-10 coding number Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state ...
Proximal fractures make up 5% of all fractures and 25% of humerus fractures, [9] middle fractures about 60% of humerus fractures (12% of all fractures), [12] and distal fractures the remainder. Among proximal fractures, 80% are one-part, 10% are two-part, and the remaining 10% are three- and four-part. [ 22 ]
Proximal humerus fractures account for approximately 4-7% of all fractures in adults. [11] [8] It is the most common fracture of the humerus, as well as the most common fracture at the shoulder girdle. [11] [8] They are more common in women than men, and occur more often in older adults.
When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it. It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head. [5] A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the ...

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 ...
