Functional Outcome of Open Reduction and Internal Fixation of Displaced Extra-Articular Scapula Fractures.

BACKGROUND

Scapular fractures are uncommon injuries of upper extremity resulting mostly from high-energy trauma. Extra-articular fractures form the majority of them. Un-displaced fractures can be managed conservatively with good results. But displaced fracture does not yield satisfactory results and needs surgical fixation. In this case series, we report our experience about such fractures.

METHODS

This was a retrospective study of 12 patients with displaced scapular body and neck fractures treated between 2015 and 2018. Scapular fractures were exposed by modified Judet approach and fixed with either 3.5 mm T buttress or recon locking plate and screws. One case had associated clavicle fracture which was fixed along with scapula. Patients were put on structured rehabilitation and followed up regularly. Functional outcome and range of motion were analyzed.

RESULTS

The patients included 10 males and two females. Mean age was 42 years. Average follow-up was 33 months. Average constant and Murley score was 80. Excellent results were seen in four patients, good results in seven patients and one patient has got fair result. The mean post-operative range of motion of the shoulder at the time of final follow-up was 140° of forward flexion, 136° of abduction, and 34° of external rotation.

CONCLUSION

Displaced extra-articular scapular fractures managed by internal fixation using T buttress locking plates and reconstruction plates give good functional outcome.
