Summary
This study introduces a less invasive posterior surgical approach for displaced inferior glenoid fractures (Ideberg type II). The technique achieved excellent fracture reduction and good functional outcomes with bony union in all patients.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Surgical Techniques
Background:
- Traditional posterior scapular surgery (Judet approach) involves significant soft-tissue injury and deltoid muscle incision.
- No prior clinical studies have reported on open reduction and internal fixation without capsular incision for displaced inferior glenoid fractures (Ideberg type II).
Purpose of the Study:
- To introduce a novel, less invasive posterior surgical approach for inferior glenoid fossa fractures.
- To evaluate the clinical outcomes of this new surgical technique.
Main Methods:
- Ten patients with displaced inferior glenoid fractures underwent open reduction and internal fixation without capsular incision.
- Postoperative CT scans assessed fracture reduction; 7 patients with over 2 years of follow-up had clinical and radiological data analyzed.
Main Results:
- All 7 patients achieved bony union within an average of 11 weeks.
- Excellent fracture reduction was noted (mean gap and step-off reduced to 0.6 mm).
- High functional scores were reported at 24 months: Constant score (89.1) and low pain (VAS 1.4), with good range of motion.
Conclusions:
- The described posterior approach for open reduction and internal fixation without capsular incision is an effective and less invasive method for treating Ideberg type II inferior glenoid fractures.
- This technique minimizes soft-tissue disruption and offers favorable clinical and radiological outcomes.
