Steinmann & Cofield report clinical and radiographic outcomes of autogenous humeral head bone grafting for segmental glenoid deficiency in 28 patients undergoing total shoulder arthroplasty, with mean 5.3-year follow-up. The study asks whether this technique produces acceptable glenoid incorporation and functional results comparable to standard TSA.
When posterior glenoid erosion is severe enough that eccentric reaming alone cannot restore version without compromising central fixation — especially in the setting of pre-existing humeral subluxation and capsular laxity — autogenous humeral head grafting with screw fixation is a validated adjunct that restores glenoid alignment with acceptable incorporation rates and 82% good-to-excellent outcomes.
Recognize that instability, not graft resorption, is the leading cause of failure in this population and must be addressed simultaneously through soft tissue balancing.
