【 摘 要 】

IntroductionLesser tuberosity osteotomy (LTO) during anatomic total shoulder arthroplasty has a 13% nonunion rate. Treatment for LTO nonunion is controversial and poorly described in the literature. The purpose of this study was to compare the surgical and nonsurgical treatment outcomes of LTO nonunion.MethodsA retrospective case series of 9 consecutive patients with LTO nonunion after primary anatomic shoulder arthroplasty at 1 institution from 2010 to 2016 were studied. Outcomes measured were radiographic evaluation of LTO on axillary X-ray, clinical range of motion (ROM), subscapularis strength, and pain at the time of LTO nonunion diagnosis and after either conservative care or surgical repair of the LTO nonunion.ResultsLTO nonunion was treated surgically in 4 and conservatively in 5 patients with average follow-up of 30 and 22 months, respectively. There were no significant differences in age, sex, or smoking status between groups. Treatment decision was a shared model of surgeon and patient. Displac...
