Summary
Open reduction and coracoacromial ligament transfer effectively treated acute Allman type-III acromioclavicular dislocations. Most patients achieved excellent or good functional outcomes, with infrequent complications and satisfactory cosmetic results.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Acromioclavicular (AC) joint dislocations, particularly Allman type-III, present significant challenges in shoulder function.
- Conservative and surgical treatments vary, with ongoing debate regarding optimal management for severe AC joint injuries.
Purpose of the Study:
- To evaluate the long-term functional outcomes and complications of open reduction and coracoacromial ligament transfer for acute Allman type-III AC dislocations.
Main Methods:
- Forty-seven patients with acute Allman type-III AC dislocations underwent open reduction and coracoacromial ligament transfer.
- Functional results were assessed at a mean follow-up of 6 years (range 1.6-10 years).
Main Results:
- 94% of patients (44/47) reported excellent or good functional results.
- Three patients experienced subluxations (3-5 mm), with two having unsatisfactory outcomes.
- Degenerative joint changes were noted in two patients with unsatisfactory results.
Conclusions:
- Open reduction and coracoacromial ligament transfer is a reliable surgical option for acute Allman type-III AC dislocations.
- The procedure demonstrates high rates of excellent/good functional outcomes and low complication rates.
- Degenerative changes and subluxation may impact long-term results.
