[Modified Mclaughlin procedure combined with locking plate for posterior shoulder dislocation with fracture]

Area of Science:

• Orthopedic Surgery
• Traumatology

Background:

• Posterior shoulder dislocation with proximal humerus fractures is a complex injury.
• The modified Mclaughlin procedure and locking plate fixation offer a potential treatment solution.

Purpose of the Study:

• To evaluate the clinical outcomes of the modified Mclaughlin procedure combined with a locking plate for posterior shoulder dislocation and proximal humerus fractures.
• To assess the efficacy and functional recovery in patients with specific fracture patterns.

Main Methods:

• A prospective study involving 7 patients (5 males, 2 females; age 37-53) with posterior shoulder dislocation and proximal humerus fractures (femoral head injury <40%).
• All patients underwent the modified Mclaughlin procedure with locking plate fixation.
• Postoperative shoulder joint motion and University of California, Los Angeles (UCLA) scores were used for evaluation.

Main Results:

• Follow-up ranged from 10 to 33 months.
• Satisfactory range of motion was observed: anteflexion/up-lift (130°-170°), extorsion (45°-75°), abduction (105°-150°).
• UCLA scores ranged from 29-34, with 1 excellent and 6 good outcomes.

Conclusions:

• The modified Mclaughlin procedure combined with a locking plate yields satisfying results for posterior shoulder dislocation with fractures.
• This surgical approach demonstrates good functional recovery and patient satisfaction.
• Potential compromise in shoulder internal rotation should be considered postoperatively.
