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 conventional stemmed implants could be available when RRH is performed.
