Perioperative fracture-dislocation of the humeral head during a resurfacing hemiarthroplasty

We report a case of perioperative fracture-dislocation of the humeral head produced during the reaming for a resurfacing replacement hemiarthroplasty (RRH) in a 79-year old woman. This is a surgical complication not previously described in the literature for this type of prosthesis design. Resurfacing humeral head implant has been noted as a useful treatment for glenohumeral arthropathies; also in elderly people; with a very low incidence of complications. However; as we report; they are possible. It is advisable that conven- tional stemmed implants could be available when RRH is performed
