Debonding of the acetabular porous coating of a hip resurfacing arthroplasty: a case report.
We report an unusual case of loosening of the acetabular component of a hip resurfacing arthroplasty due to debonding of the titanium surface coating from the acetabular shell. A 41-year-old male scaffolder had bilateral hip resurfacings in 2006. ⋯ This was subsequently revised to a cemented total hip arthroplasty. Debonding of the surface coating was suspected on radiographs prior to the revision procedure, and was confirmed intraoperatively.

Hip fractures occur commonly and are a cause of disability for older adults and lead to increased dependence and requirements for social support. Dementia is one of the possible risk factors for falling and hip fracture, a potential source for complications during surgery and during the postoperative period, difficulties in rehabilitation and a risk factor for hip fracture reccurence. However, in previous studies of hip fracture patients, cognitive status has not been formally assessed during the inpatient stay and diagnosis was based only on previous history. ⋯ Dementia is very common in older patients admitted for surgery to a general hospital and extremely common in those with hip fracture. It seems that dementia is under diagnosed in elderly hospitalised patients. Our data confirm that dementia is a major risk factor for hip fracture in the elderly.
