It gives attachment to the supraspinatus infraspinatus and teres minor muscles. The proximal humeral metaphysis and shaft are exposed via a craniolateral approach extending from the proximal end of the greater tubercle distally 10.

Greater tubercle of humerus. Greater Tubercle of Humerus. The structure indicated is the greater tubercle of the humerus. The greater tubercle lies lateral to the head of the humerus as serves as the point of attachment for three of the rotator cuff musclesThere are three flat facets to which these three muscles attach.
Isolated fractures of the greater tuberosity of the humerus can occur in anterior shoulder dislocations or as the result of an impaction injury against the acromion or superior glenoid. Greater tuberosity fractures may be associated with partial-thickness rotator cuff tears and labral tears which m. The greater tubercle is located laterally on the humerus and has anterior and posterior surfaces.
It serves as an attachment site for three of the rotator cuff muscles supraspinatus infraspinatus and teres minor - they attach to superior middle and inferior facets respectively on the greater tubercle. The greater tubercle is the most lateral portion of the proximal end of the humerus. It consists of three smooth and flat impressions at the posterosuperior aspect for the attachment of muscles.
From superior to inferior the muscles that attach at these impressions are the. Most non-displaced humeral greater tubercle fractures are successfully treated conservatively non-surgically. References 1 public playlist includes this case.
MS by Albert Guillemette. Promoted articles advertising How to use cases. You can use Radiopaedia cases in a variety of ways to help you learn and teach.
The greater tubercle is the most lateral part of the proximal end of the humerus. Three impressions mark it at the upper posterior aspect all of which serve for the attachment of muscles. Three impressions mark it at the upper posterior aspect all of which serve for the attachment of muscles.
Greater tuberosity fractures of the humerus which would be classified as a type I fracture using Neers classification system35 Most of the recent published work on proximal humeral fractures deals with the manage-ment of 3- and 4-part fractures361022334042 There are typically 2. However there is a transverse humeral ligament which projects from the lesser tubercle to the greater tubercle of the humerus and converts the humeral intertubercular groove into a canal which the tendon of the biceps brachii long head travels through on its way from its origination on the supraglenoid tubercle of the scapula to the radius. The larger of the two tubercles next to the head of the humerus.
It gives attachment to the supraspinatus infraspinatus and teres minor muscles. The proximal humeral metaphysis and shaft are exposed via a craniolateral approach extending from the proximal end of the greater tubercle distally 10. Extension of the approach proximally allows access to repair Salter and Harris type I fractures of the proximal humerus.
The greater tubercle is situated on the lateral side of the humeral head. This tubercle acts as the attachment for the tendons of the supraspinatus infraspinatus and teres minor muscles. The greater tubercle is positioned laterally.
Three large smooth sides represent its superior surface and posterior surface for muscle tendon attachment. The greater tuberosity located on the humerus next to the head of the humerus and the lesser tuberosity is a large bulbous protrusion from this long arm bone that serves as an attachment point for several muscles. Four of these muscles control movement of the shoulder.
Humerus Greater Tubercle Fracture The proximal humerus is the section of the upper arm bone close to the shoulder. In young adults fractures of the proximal humerus are often caused by high -energy trauma like a sports injury or car accident. In the older population they are usually caused by a.

Un Estudio en Cadaver de su Morfometria y Morfologia. The greater tubercle is located laterally on the humerus and has anterior and posterior surfaces. It serves as an attachment site for three of the rotator cuff muscles supraspinatus infraspinatus and teres minor - they attach to superior middle and inferior facets respectively on the greater tubercle.
It is located laterally on the humerus and bears anterior and posterior surfaces. It acts as an attachment site for three rotator cuff muscles the supraspinatus infraspinatus and teres minor. These muscles attach to superior middle and inferior facets respectively on the greater tuberosity.
Most non-displaced humeral greater tubercle fractures are successfully treated conservatively non-surgically References Rouleau D Mutch J Laflamme G. Surgical Treatment of Displaced Greater Tuberosity Fractures of the Humerus. Greater tubercle of humerus.
Lateral epicondyle of humerus. Anatomical neck of humerus. Surgical neck of humerus.
Sets found in the same folder. The teres minor muscle originates from the lateral border of the scapula and inserts on the greater tubercle of the humerus. The supraspinatus muscle has its origin in the supraspinatous fossa and inserts on the greater tubercle of the humerus similar to the teres minor muscle.
The fourth muscle of the rotator cuff is the infraspinatus muscle. Greater tuberosity fractures may be treated successfully without surgery. Isolated fractures of the greater tuberosity account for approx - imately 20 of all proximal humeral fractures Chun et al.
1994 Kim et al. 2005 Gruson et al. They are often associated with anterior glenohumeral dislocation or can.
B The depression type involves an inferiorly displaced and impacted greater tuberosity. C The split type is a large fragment characterized by a vertical fracture line.
