Clinical Evaluation-Physical Findings

Distinguishing anterior shoulder pain caused by biceps tendon disorders as opposed to subacromial impingement can be difficult, as these two entities usually co-exist. Although there are some exam maneuvers, which attempt to isolate the biceps tendon, there is still a fair amount of overlap and the definitive diagnosis of isolated biceps tendon pathology is extremely […]

Complications and Pitfalls-Recurrence

Recurrence is the most frequently reported complication after open and arthroscopic surgery for anterior instability. Recurrence may be secondary to new trauma or to atraumatic events.Patients with traumatic recurrence of their instability usually have better post-operative results after revision surgery than patients with atraumatic recurrence. The recurrence rate is related to the number of prior […]

Humeral Bone Deficiency

Humeral head defects are commonly present in patients with shoulder instability. The defects are usually small and carry the eponym Hill-Sachs lesion when secondary to anterior instability and reverse Hill-Sachs lesions when secondary to posterior instability.

Although quite ubiquitous in recurrent anterior shoulder instability, the management of large Hill-Sachs defects remains controversial especially in […]

Capsular Lesions

Traumatic intra-substance injury of the joint capsule is commonly associated with anterior dislocation. Depending on the magnitude of the anterior shear force, either plastic deformation or a complete tear of the joint capsule can occur.

The recognition of a concomitant posttraumatic capsular laxity or rupture and a Bankart lesion is essential in order to select […]

Skeletal Lesions

The limited constraint provided by the glenoid is further decreased by bony lesions of the anterior or posterior glenoid rim. These lesions may result from an osseous (anterior or posterior) Bankart lesion, a displaced glenoid fracture, or wear and erosion of the glenoid rim as a result of multiple recurrent dislocations.

Resisted extension

Positioning.

The subject stands with the arm alongside the body, the elbow flexed to 90° and the forearm in supination. The examiner stands level with the elbow. One hand supports the distal part of the forearm and the other hand is on top of the shoulder.

Procedure.

Resist the subject’s attempt to extend the elbow.

Passive pronation

Positioning.

The subject stands with the arm hanging and the elbow bent to a right angle. The examiner stands in front of the subject. Both hands encircle the distal forearm in such a way that the heel of the contralateral hand is placed against the volar part of the ulna and the fingers of the […]

Passive tests-Passive internal rotation

Positioning.

The subject stands with the upper arm alongside the body and the elbow flexed to a right angle. The examiner stands level with the subject’s arm and stabilizes the elbow with his trunk. One hand is placed on the opposite shoulder to stabilize the shoulder girdle and trunk; the other takes hold of […]

Dislocation of the Shoulder Joint

Dislocation of the shoulder joint is a relatively common injury in sports such as ice hockey, team handball, American football, rugby, riding, alpine skiing, skating, and wrestling. Shoulder dislocations are 3 times more common in men 20–30 years old, than in persons aged over 30 years. The male to female ratio for primary dislocation is […]

Aneurysmal Bone Cyst

Basics Description Destructive, painful, lytic bone lesions occurring in young patients May occur primarily in bone (de novo) or develop within another benign bone lesion Can be locally aggressive and can cause a bone to balloon as a result of aneurysmal cystic expansion Occurs most often at the proximal ends of long bones and […]
