This study shows the modified Weaver-Dunn procedure offers excellent outcomes for acromioclavicular joint injuries. The technique provides significant functional improvement with manageable complication rates.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Surgical techniques
Background:
- Acromioclavicular (AC) joint injuries require effective management strategies.
- The modified Weaver-Dunn (mWD) procedure offers a surgical approach for AC joint injuries.
Purpose of the Study:
- To describe a modified Weaver-Dunn procedure using transosseous bone tunnels and coracoid suture augmentation.
- To evaluate the clinical outcomes and complications associated with this mWD technique.
Main Methods:
- Retrospective review of 39 patients undergoing primary mWD procedure.
- Analysis of clinical course, complications, and radiographic evaluations.
- Assessment of patient-reported outcomes including satisfaction, ASES, SANE, and SST scores.
Main Results:
- 28 patients (72%) with a mean follow-up of 37.5 months were included.
- Significant improvement in ASES scores (42.2 ± 21.8 points, P < 0.001).
- Excellent patient satisfaction and functional scores were reported; 10.7% complication rate.
Conclusions:
- The modified Weaver-Dunn technique yields excellent functional and radiographic outcomes for AC joint injuries.
- Complication and revision rates are comparable to existing literature, supporting its efficacy.
