title: Works in progress #7. Clinical experience with the Accu-Path threaded acetabular cup. A preliminary report.
abstract: Clinical experience with the Accu-Path threaded titanium hemispheric cup is presented. A series of 62 cases was followed for an average of 28.1 months (range, 6 to 48). Primary surgery was performed in 50 cases and revision surgery in 12. The surgical technique is described in detail. Preoperative Harris scores improved from 28 to 93 in primary cases and from 24 to 84 in revision cases. Complications included 3.2% dislocation, 3.2% loss of cup position, and 1.6% recurrent subluxation. The overall reoperation rate was 8% (8% in primary surgery and 8.3% in revision surgery). Roentgenographic analysis is discussed. The importance of preservation of the subchondral plate and a rim fit in the use of this implant is stressed. It is not indicated in those with loss of the plate due either to prior surgery (as in revision) or in aggressive over-reaming in primary cases. Although the overall results were encouraging, caution was recommended--especially in revision surgery or in the patient with severe osteopenia.
