Double Plating With Fibular Allograft Reinforcement of Scapular Spine Fracture After Reverse Shoulder Arthroplasty.

Scapular spine fractures following reverse shoulder arthroplasty have been associated with complications that include nonunion and fixation failure. This Technical Note presents a surgical approach for enhancing the stability and strength of spine fracture osteosynthesis. The method involves the utilization of double plating in conjunction with fibular allograft reinforcement anchored in the supraspinous fossa to provide support under the acromion. The allograft, offering an enhanced structural integrity, may contribute to an improved rate of bone fusion and clinical outcomes without donor site morbidity.
