The Monk Hard-Top prosthesis for displaced intracapsular fractures of the femoral neck.

The Monk Hard-Top prosthesis was inserted without operative mortality in 85 patients, with an average age of 81 years, presenting with Intracapsular Fracture of the Femoral Neck, Garden grade 3 or 4. At review, 60% of the patients walked unaided, without pain. Only 6% of those reviewed had a poor functional outcome. Fifty-three per cent of the patients returned to their previous environment and 47% had died 6 months postoperatively. The prosthesis is more difficult to dislocate, once inserted properly, than either a Thompson Hemiarthroplasty or a Primary Total Hip replacement. It is less likely to sustain Component Disassembly than other types of bipolar hemiarthroplasty. The Monk Hard Top Prosthesis is recommended for the treatment of Garden grade 3 or 4 Intracapsular Fractures of the Femoral Neck in elderly people.
