Kickstand Technique for Treatment of Valgus-Impacted Proximal Humerus Fractures

Abstract

Purpose: Describe a new technique using a minimally invasive surgical intervention for the treatment of valgus-impacted proximal humerus fractures. The Kickstand technique is a novel approach that offers reliable fixation and union without the need for additional hardware. Materials and Methods: A retrospective case series of 3 patients with valgus-impacted proximal humerus fractures was treated with this Kickstand technique using an intramedullary fibular allograft. Postoperative x-rays and outcomes are presented. Results: The Kickstand technique was used to address valgus-impacted fractures in 3 patients. Postoperative range of motion and shoulder outcome scores were reported at 2 years for patients A and B, and at 1 year for patient C (Active range of motion external rotation: 28 degrees; Active range of motion elevation: 140 degrees; Simple Shoulder Test-12: 11; American Shoulder and Elbow Standardized Shoulder Assessment: 78). Postoperative Grashey and lateral x-rays for each patient show union of the valgus-impacted humerus. Conclusions: The Kickstand technique using intramedullary fibular allograft is an alternative fixation technique for displaced valgus proximal humerus fracture. It has the advantage of avoiding additional metallic hardware and allowing early motion but requires the use of intramedullary fibular allograft which can interfere with future use of stemmed humeral prosthesis.
