Floating clavicular injury: treatment of combined midshaft fracture and acromioclavicular separation with a dual plating technique

Mid-clavicle fracture with dislocation of the ipsilateral acromioclavicular joint treated with Endobutton system: A case report and review of the literature

RATIONALE

Acromioclavicular joint (ACJ) dislocation combined with ipsilateral midclavicular fracture is extremely unusual and is a high-energy injury to the shoulder. A review of the literature divides the treatment of clavicular fractures is divided into nonsurgical treatment, plates, and intramedullary nailing, while the options for ACJ dislocation are elastic fixation and rigid fixation. However, there is still a lack of consensus about the most appropriate way to treat this shoulder injury. This case report involves a mid-clavicle fracture with dislocation of the ipsilateral ACJ, which was classified as type V according to Rockwood classification.

PATIENT CONCERNS

A 65-year-old man came to the emergency department after a traffic accident in which he was driving a motorcycle that collided with another motorcycle and his right shoulder collided directly with the ground. Digital radiography (DR) and computed tomography (CT) scans of the right shoulder joint showed mid-clavicle fracture with dislocation of the ipsilateral ACJ, which was classified as type V according to Rockwood classification.

DIAGNOSES

The diagnosis of mid-clavicle fracture with dislocation of the ipsilateral ACJ was confirmed by DR and CT.

INTERVENTIONS

The patient was treated with a clavicle plate combined with the double Endobutton technique.

OUTCOMES

After a 6-month follow up, the patient had excellent results for shoulder range of motion and functional. The patient's Constant-Murley score is 92.

LESSONS

Mid-clavicular fracture with a high-energy injury is highly suspicious and requires perfect shoulder CT or bilateral shoulder stress position DR to confirm whether there is a combined ACJ dislocation.

Simultaneous Clavicle Fracture and Acromioclavicular Joint Dislocation: Novel Surgical Technique: A Case Report

CASE

A 41-year-old man sustained a midshaft clavicle fracture with associated type IV ipsilateral acromioclavicular joint (ACJ) dislocation. The clavicle was fixed with a locking plate and ACJ stabilized with a novel technique: 2 metal anchors with preloaded suture fixed at the coracoid process, looping the sutures over the clavicle, and passing through the plate holes without clavicle bone drilling. Excellent functional outcomes for range of motion, pain, and functional scores persisted 2 and a half years after surgery.

CONCLUSION

The described surgical technique achieved exceptional short-term outcomes, sparing clavicle bone stock and allowing an early return to sports.
