An ALPSA (anterior labral periosteal sleeve avulsion) lesion is an injury at the front of the shoulder associated with shoulder dislocation. [1] References
Anterior shoulder dislocation and/or repeated anterior shoulder subluxations. [2] Diagnostic method: X-ray and MRI. Differential diagnosis: Anterior labroligamentous periosteal sleeve avulsion, Rotator Cuff Tears, SLAP Lesion, Impingement, Perthes lesion, Glenolabral articular disruption, Humeral avulsion of the glenohumeral ligament. [2]
During a periosteal avulsion, the periosteum (a fibrous layer that surrounds a bone) detaches the bone's surface. An example of a periosteal avulsion is an ALPSA (anterior labral periosteal sleeve avulsion).
Anterior shoulder dislocation while carrying a frail elder. A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1]
Humeral avulsion of the glenohumeral ligament (HAGL) is defined as an avulsion (tearing away) of the inferior glenohumeral ligament from the anatomic neck of the humerus. [1] In other words, it occurs when we have disruption of the ligaments that join the humerus to the glenoid. HAGL tends to occur in 7.5-9.3% of cases of anterior shoulder ...
SLAP is an acronym for "Superior Labrum Anterior and Posterior". [1] SLAP lesions are commonly seen in overhead throwing athletes but middle-aged labor workers can also be affected, and they can be caused by chronic overuse or an acute stretch injury of the shoulder.
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
