Potential outcome of locking compression plate in proximal humerus fractures

Background Fractures of proximal humerus bone needs immediate attention as the delayed treatment might result in non-union, malunion, and avascular necrosis which are responsible for the pain and dysfunction. The aim of the present study is to evaluate the functional outcome of displaced proximal humerus bone fractures that are surgically managed by locking compression plate and to assess the potential complication.

Methods The present study is the combination of both prospective and retrospective in which 30 patients with either Neer’s three part or Neer’s four-part proximal humerus fractures which were fixed with locking plate by a single surgeon. Functional outcome was measured by Constant Murley scoring (CMS) system.

Results The final follow-up of the study showed that 21 patients (70%) had the result that ranged from good to excellent score whereas, 6 patients (20%) had moderate score and 3 patients had poor score in functional outcome according to CMS system. During follow-up, 3 complications (10%) were encountered.

Conclusions The study concluded that proximal humerus locked compression plate is a valuable surgical method for the fixation of comminuted fractures of the proximal humerus as it is associated with excellent functional outcome. It also provides a stable fixation to permit early mobilization. Regaining medial cortical contact and establishing anatomical reductions decreases the complications that are associated with plate fixation.
