Recurrent posterior dislocation of the shoulder: treatment using a bone block
Summary
The posterior bone-block procedure effectively treated recurrent posterior shoulder dislocations in five patients, allowing them to return to full activity. This surgical technique shows promise for managing this uncommon shoulder instability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Instability
Background:
- Acute posterior shoulder dislocations are rare injuries.
- Recurrent posterior dislocations require surgical intervention.
- Existing treatments include soft-tissue repair, osteotomies, and bone grafting.
Purpose of the Study:
- To evaluate the efficacy of the posterior bone-block procedure for treating recurrent posterior shoulder dislocations.
- To assess patient outcomes and complications following this surgical technique.
Main Methods:
- A series of five patients with recurrent posterior shoulder dislocations underwent the posterior bone-block procedure.
- Patients were followed for 2.5 to 8 years post-surgery.
- Outcomes included return to activity, patient-reported pain, and radiographic assessment.
Main Results:
- The posterior bone-block procedure successfully prevented recurrent dislocations in all five patients.
- All patients returned to unrestricted activity and recreational sports without pain.
- Complications included one subsequent anterior dislocation and two revision scars; no graft resorption occurred.
Conclusions:
- The posterior bone-block procedure is an effective surgical option for recurrent posterior shoulder dislocations.
- This technique offers a high rate of success in restoring shoulder stability and function.
- Potential complications, though infrequent, should be considered in patient counseling.
