Summary
A modified posterior surgical approach to the scapula was evaluated in cadavers and used in two fracture cases. This technique safely exposes the scapular neck and glenoid, protecting critical neurovascular structures.
Area of Science:
- Orthopedic Surgery
- Anatomy
Background:
- Fractures of the scapular neck and glenoid fossa present surgical challenges.
- Existing posterior approaches may have limitations in accessing these complex structures.
Observation:
- A modified C-shaped posterior incision was developed and tested on 20 cadavers.
- The approach involves lateral reflection of posterior deltoid fibers and mobilization of the infraspinatus muscle.
- Osteotomy of the acromion allows access to superior glenoid surfaces.
Findings:
- The modified approach provides access to the posterior scapular neck and glenoid.
- Key neurovascular structures, including the suprascapular neurovascular bundle, circumflex scapular artery, and axillary nerve, were identified and protected.
- Specific distances from critical bony landmarks to these neurovascular structures were documented.
Implications:
- This technique offers a viable surgical option for complex scapular fractures.
- Understanding the anatomical relationships is crucial for preventing iatrogenic injury during surgery.
- Further clinical studies may validate the efficacy and safety of this modified posterior approach.
