Summary
This study shows arthroscopic double-row suture anchor fixation (ADSF) is effective for treating comminuted, displaced greater tuberosity (GT) fractures. Patients experienced significant pain reduction and improved shoulder function after the arthroscopic procedure.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Traumatology
Background:
- Greater tuberosity (GT) fractures, particularly comminuted and displaced types, present challenges in orthopedic treatment.
- Arthroscopic techniques offer potential advantages for managing complex shoulder fractures.
Purpose of the Study:
- To evaluate the early clinical outcomes of arthroscopic double-row suture anchor fixation (ADSF) for comminuted, displaced GT fractures.
- To assess the efficacy and safety of the ADSF technique in a series of patients.
Main Methods:
- Retrospective case series of 16 patients with displaced, comminuted GT fractures treated with ADSF.
- Follow-up at a mean of 24 months, assessing range of motion, Visual Analog Scale (VAS), University of California, Los Angeles (UCLA) rating scale, and American Shoulder and Elbow Surgeons (ASES) score.
- Inclusion criteria required at least 5 mm of fracture displacement.
Main Results:
- Significant improvements in VAS scores (9.4 to 1.2), UCLA scores (mean 31), and ASES scores (mean 88.1).
- Functional gains included improved forward flexion (148.7°), abduction (145°), and external rotation (24°).
- Internal rotation improved significantly, reaching the L1 vertebral level.
Conclusions:
- The ADSF technique demonstrates encouraging early results for treating displaced, comminuted GT fractures.
- Arthroscopic management of these fractures should be considered, potentially expanding its indications.
