Acromioclavicular Separation

Separated Shoulder


Presentation

  • A case report of a coracoid fracture of the scapula with acromioclavicular separation is presented. The treatment consisted of surgical reduction and fixation of the acriomioclavicular separation and of the coracoid fracture.[ncbi.nlm.nih.gov]
  • The authors of "Posterior Distal Clavicle Beveling for Chronic Nonincarcerated Type IV Acromioclavicular Separations: Surgical Technique and Early Clinical Outcomes" present a case series reporting convincing results concerning functional outcomes and[ncbi.nlm.nih.gov]
  • This article presents a review of literature on this combined injury pattern. A variety of treatment approaches have been put forth, including nonoperative, operative, and hybrid management of the two distinct injuries.[ncbi.nlm.nih.gov]
  • Abstract Three cases demonstrating avulsion of the coracoid process from the scapula associated with acromioclavicular separation are presented.[ncbi.nlm.nih.gov]
  • We present a case of 39-year-old female with a scapulothoracic dissociation and acromioclavicular (AC) separation and who had fixation of the AC joint with a locking plate, coracoclavicular screw, and transarticular AC screw.[ncbi.nlm.nih.gov]
Asymptomatic
  • After healing of the acromioclavicular separation and the coracoid fracture the left shoulder was asymptomatic with a full range of motion.[ncbi.nlm.nih.gov]
  • One required reoperation for an improperly placed loop, and one had definite over-reduction of the clavicle on the acromion but remained asymptomatic.[ncbi.nlm.nih.gov]
  • RESULTS: At 12 weeks postinjury, the athlete was pitching asymptomatically, and gradually returned to regular play.[ncbi.nlm.nih.gov]
  • It has been reported that an increase in the coracoclavicular distance of the injured shoulder over the asymptomatic contralateral shoulder by 25-50% represents complete coracoclavicular ligament disruption 10,11.[radsource.us]
Noncompliance
  • Of the two initial poor results, one required revision 1 month post-operatively because the patient was noncompliant, and the other required manipulation under anesthesia 3 months after surgery.[ncbi.nlm.nih.gov]
Overeating
  • Use of autogenous free tendon graft to anatomically reconstruct the acromioclavicular and coracoclavicular ligaments offers several advantages over other surgical techniques.[ncbi.nlm.nih.gov]
  • One required reoperation for an improperly placed loop, and one had definite over-reduction of the clavicle on the acromion but remained asymptomatic.[ncbi.nlm.nih.gov]
  • No tenderness over the sternoclavicular joint was noted. A left anteroposterior radiograph of the shoulder revealed complete separation of the acromioclavicular joint (Panel C).[nejm.org]
  • Abstract The issue of managing type III acromioclavicular (AC) separations remains controversial, and decisions about using operative versus conservative management have undergone many distinct changes over the years.[ncbi.nlm.nih.gov]
  • Over time Constant score improved significant to an excellent score (mean 94, range 86-100, SD 4; p CONCLUSION: All patients participated in sporting activities after anatomical reconstruction of high-grade (Rockwood Type V) ACJ-separation.[ncbi.nlm.nih.gov]
Ulcer
  • However, these drugs may have side effects, like an increased risk of bleeding and ulcers or heart attacks and strokes. They should not be used for extended periods of time, unless your doctor specifically says otherwise.[webmd.com]

Treatment

  • Abstract Treatment of acute type III acromioclavicular separation is controversial. In some patients, nonoperative treatment is associated with pain, weakness, and stiffness.[ncbi.nlm.nih.gov]
  • Other reported treatment options and recommendations are reviewed.[ncbi.nlm.nih.gov]
  • Operative treatment is sought only when the athlete remains symptomatic with painful instability. However, some do support early intervention in the overhead athlete.[ncbi.nlm.nih.gov]
  • Abstract The purpose of this study was to examine the results of the two major methods of treatment of complete acromioclavicular separation: surgery and nonsurgical techniques.[ncbi.nlm.nih.gov]
  • The increasing use of minimally invasive techniques allows for an easier diagnosis and simultaneous treatment of the additional pathologies.[ncbi.nlm.nih.gov]

Prognosis

  • […] motion Abnormal widening of the AC joint due to disruption of the AC ligament CC separation is the more important soft tissue injury Extent of CC separation has direct effect on degree of AC separation Classification Type Anatomy Radiographic findings Prognosis[learningradiology.com]
  • […] distance normal: 10-13 mm greater than 5 mm asymmetry (compared to radiographs of the contralateral side) superior displacement of the distal clavicle the undersurface of the acromion should be level with the under the surface of the clavicle Treatment and prognosis[radiopaedia.org]
  • What Is the Prognosis for a Shoulder Separation? The prognosis for simple separations is generally good if there is just a strain and the ligaments are not greatly damaged. Recovery time depends on the extent of the injury.[emedicinehealth.com]
  • Classification of AC separation The importance of identifying the injury type cannot be overemphasised because the treatment and prognosis hinge on an accurate diagnosis.[sportsinjurybulletin.com]

  • Epidemiology The AC joint is involved in anywhere from 3% up to 40% of traumatic shoulder girdle injuries, making it one of the more common athletic injuries. It generally occurs in males (5:1 to 10:1) between the ages of 20 and 30 years.[orthopaedicsone.com]

Prevention

  • This vaccine is a booster shot used to help prevent diphtheria and tetanus. How can I manage my symptoms? Apply ice. Apply ice on your injury for 15 to 20 minutes every hour for the first 1 to 2 days.[drugs.com]
  • AC Joint Separation Prevention: Because injuries of this nature are caused by traumatic events, there is not a lot that can be done to prevent them.[mmarmedical.com]
  • With minor shoulder separation surgery, the surgeon may just trim back the collarbone to prevent any friction occurring between it and the AC so that reattachment can occur.[rehabmypatient.com]
  • Use a sling or shoulder immobilizer to prevent further injury until you get medical treatment. Then follow the doctor's advice about whether or not to use a sling. Take anti-inflammatory painkillers.[webmd.com]
