What is a Neer fracture?
The Neer system divides the proximal humerus into four parts and considers not the fracture line, but the displacement as being significant in terms of classification. The four parts are the humeral head, the greater tuberosity, the lesser tuberosity and the humeral shaft. Displacement is on a per-part basis.
What is a 3 part fracture of surgical neck of humerus?
3-PART FRACTURE: This is when the proximal humerus is broken into three pieces, and there are then two fracture lines on x-ray. This most often involves the greater tuberosity and the surgical neck of the humerus.
What is the Neer classification?
The concept of the Neer classification is dividing the proximal humerus into 4 segments (humeral head, greater tuberosity, lesser tuberosity, and humeral shaft) and classifying the proximal humeral fractures by the number of displaced segments.
What is a Subcapital humerus fracture?
Fractures of the surgical neck of the humerus include the typical subcapital humeral fracture (a two-fragment fracture) as well as most three-fragment and all four-fragment fractures. Many different options for osteosynthesis have been described.
What is humeral neck fracture?
Fractures of the anatomical neck of the humerus are an extremely rare pathological entity in the field of orthopedic surgery. One of the most feared complications associated with anatomical neck fracture of the humerus is avascular necrosis (AVN).
What is morphological neck of humerus?
It affords attachment to the articular capsule of the shoulder-joint, and is perforated by numerous vascular foramina. Fracture of the anatomical neck rarely occurs. The anatomical neck of the humerus is an indentation distal to the head of the humerus on which the articular capsule attaches.
Why is it called surgical neck of humerus?
As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons.
What is a nondisplaced fracture of the humerus?
Displaced humerus fractures Non-displaced fractures are still broken bones, but the pieces weren’t moved far enough during the break to be out of alignment. Displaced fractures are much more likely to require surgery to repair.
What is Subcapital fracture?
Subcapital fracture is the most common type of intracapsular neck of femur fracture. The fracture line extends through the junction of the head and neck of femur.
Where is the neck of the humerus?
The anatomical neck of the humerus is located distal to the head of the humerus, at an oblique angle to the shaft of the humerus. The surgical neck of the humerus on the other hand is a constriction of the humerus located inferior to the greater and lesser tubercles.
What is the difference between anatomical neck and surgical neck of humerus?
Why surgical neck of humerus is called so?
