【 摘 要 】

IntroductionLesser tuberosity osteotomy (LTO) is an attractive option for subscapularis management during anatomic shoulder arthroplasty due to the biomechanical strength and reliable bone-to-bone healing. Patients with humeral head avascular necrosis (AVN) may have compromised bone healing, and the outcomes of LTO during AVN are unknown.MethodsA retrospective consecutive case series of 6 patients with Cruess grade 4 or 5 humeral head AVN who underwent anatomic shoulder arthroplasty with LTO from 2010 to 2016 was performed. Postoperative radiographic evaluation for LTO healing at 6 months was analyzed, and clinical outcomes at latest follow-up, including range of motion (ROM), strength, and pain were studied.>ResultsAverage age was 50.3 years. AVN was secondary to sickle cell in 1 patient, steroid use for systemic lupus erythematosus in 4, and chronic alcoholism in 1. By 6 months after arthroplasty, 100% had radiographically united and healed LTO. Patients averaged 140 ± 21° of active forward elevation an...
