Bone buttress operation for recurrent anterior shoulder dislocation in epilepsy

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Trauma Management

Background:

• Generalized convulsions, such as grand mal epilepsy, can lead to anterior or posterior shoulder dislocations.
• Recurrent anterior shoulder dislocations often result from bony damage to the glenoid rim and humeral head, leading to high failure rates with standard soft-tissue repair.
• Existing soft-tissue stabilization procedures are frequently unsuccessful in patients with significant bony defects.

Purpose of the Study:

• To evaluate the efficacy of a newly devised bone buttress operation for managing recurrent anterior shoulder dislocations in patients with generalized convulsions.
• To assess the outcomes and patient satisfaction following this bone grafting procedure.

Main Methods:

• A bone buttress operation was performed on 14 patients experiencing recurrent anterior shoulder dislocations secondary to grand mal epilepsy.
• The procedure involved securing an autograft or allograft to the deficient anterior glenoid, creating an extended articular surface.
• Postoperative follow-up assessed dislocation recurrence, patient satisfaction, and range of motion.

Main Results:

• No further shoulder dislocations occurred in any of the 14 patients after the bone buttress operation.
• All patients reported satisfaction with the surgical outcome.
• A minor restriction in the range of shoulder movement was observed in some patients.

Conclusions:

• The bone buttress operation is a highly effective treatment for recurrent anterior shoulder dislocations in patients with generalized convulsions and associated bony damage.
• This surgical approach offers a successful alternative to standard soft-tissue procedures, demonstrating excellent outcomes and patient satisfaction.
• The bone buttress procedure is recommended as the preferred surgical option for this challenging orthopedic condition.
