Ultrasound guidance improves the accuracy of the acromioclavicular joint
infiltration: a prospective randomized study.
13), (14) Furthermore, acromioclavicular joint
involvement is very infrequent in Tbc arthritis.
Evaluation and treatment of acromioclavicular joint
If the scapula is sitting higher than normal then there will be some rotational strain at the acromioclavicular joint
Recently, Sahara and colleagues performed a three-dimensional (3D) kinematic analysis of the acromioclavicular joint
using magnetic resonance imaging (MRI) and observed that the scapula rotated 35[degrees] on an axis that passed through the insertions of the acromioclavicular and coracoclavicular ligaments on the acromion and coracoid process, respectively.
This report highlights the need for a high index of suspicion for associated uncommon injuries, such as coracoid fractures, when evaluating and treating common injuries such as clavicle fractures and acromioclavicular joint
The procedure, performed by a consultant musculoskeletal radiologist, showed fluid and inflammatory change in and around the acromioclavicular joint
and extensive hypervascular tissue deep to the deltoid anteriorly.
The pin will exit the lateral fragment under the skin posteromedial to the acromioclavicular joint
Subperiosteal dissection of the clavicle was performed, extending approximately 2 cm from the fracture site medially and a few millimeters laterally, in order to maintain the vascular supply to the small lateral fracture fragment attached to the acromioclavicular joint
The acromioclavicular joint
(AC) is a diarthrodial joint, stabilized by the coracoclavicular ligaments (conoid and trapezoid), the superior and inferior AC ligaments, and the AC capsule (Fig.
Cryptococcal arthritis of the acromioclavicular joint
Three scenarios were designed for rotator cuff disorders, two for frozen shoulder, two for glenohumeral instability, and one each for glenohumeral arthritis, acromioclavicular joint
injuries, and acute trauma with resultant fracture.
Lastly, there is a high incidence of associated pathology and injuries with SLAP lesions, including rotator cuff disorders (partial-thickness rotator cuff tears, 40% to 29%, and full-thickness rotator cuff tears, 11%), Bankart lesions (22%), acromioclavicular joint
arthrosis (16%), and glenohumeral chondromalacia (10%).
The axis of rotation for abduction/adduction approximated the axis of the acromioclavicular joint
and was aligned perpendicular to the coronal plane.
Radiographs of her shoulders showed only mild degenerative changes about the acromioclavicular joints
, and other normal studies included brainstem auditory evoked response, electroencephalography, magnetic resonance imaging of the brain, and a Mini-Mental State Examination score of 30 (with MQ of 161 and IQ of 113, and with verbal IQ of 114 and performance IQ of 108).
