Ac Joint Clavicle Fracture

Chronic ac dislocations can result in chronic pain and instability.

Ac joint clavicle fracture. Complications can include a collection of air in the pleural space surrounding the lung pneumothorax injury to the nerves or blood vessels in the area and an unpleasant appearance. It concerns to a young patient who had a bike fall and had this type of pathology had been operated and obtained excellent clinic result. The clavicle carries the distinction of being the first long bone to. This is a children s fracture also called a pseudodislocation of the acromioclavicular joint because there is a fracture of the distal clavicle but the acromioclavicular joint remains intact figure 12 2e.

A clavicle fracture also known as a broken collarbone is a bone fracture of the clavicle. The coracoclavicular ligaments remain attached to the thick periosteal sleeve whereas the proximal fragment ruptures through the thin. Symptoms typically include pain at the site of the break and a decreased ability to move the affected arm. Typically a displaced intra articular fracture will result in disruption of part of or the entire acromioclavicular joint capsule and therefore the joint is usually readily apparent.

1 the segmental clavicle fracture is an uncommon pattern with one study showing 0 8 of clavicle fractures to be segmental. Although not as common as midshaft clavicular fractures distal clavicle fractures pose unique challenges given the proximity to the acromioclavicular joint stabilizers 7. Operative complications include implant migration clavicle or coronoid fracture osteolysis loss of reduction erosion of cerclage material through clavicle or coronoid ac joint arthrosis and chronic pain. It is placed between the thorax and shoulder joint and it transmits the weight from the upper limb to the body.

The acromion is the headquarters for the deltoid muscle and connects to the collarbone or clavicle to form the ac joint or acromioclavicular joint. The clavicle fracture can be very painful and any movement of the shoulder can aggravate the pain. The clavicle is one of the most commonly fractured bones in the body with an incidence ranging from 2 6 to 5 of all fractures. Problems often occur to this.

1 through the sternoclavicular and acromioclavicular joints the clavicle contributes to the overall motion of the upper extremity through attachments to important mobilizers of the upper extremity. Above the rotator cuff is a bony mass that sits on the shoulder blade or scapula called the acromion. Following reflection of the deltoid the distal clavicle fracture site is identified and cleared of any hematoma or debris. The purpose is to present a very unusual case of the acromioclavicular joint inferior dislocation associated with the clavicle fracture.

The lateral end of the clavicle articulates with the acromion part of scapula and forms the acromioclavicular joint. The patient describes landing directly onto his head and left. This constitutes the top of the shoulder.
