However, subluxation, which we define as a clinically recognised episode of incomplete movement of the femoral head outside the acetabulum with spontaneous reduction, has not been studied previously. Out of a total of 2521 hip replacements performed over 12 years by one surgeon, 30 patients experienced subluxations which occurred in 31 arthroplasties. Data were collected prospectively with a minimum follow-up of two years. Subluxation occurred significantly more frequently after revision than after primary hip replacement, and resolved in 19 of 31 cases (61.3%). In six of the 31 hips (19.4%) the patient subsequently dislocated the affected hip, and in six hips (19.4%) intermittent subluxation continued. Four patients had a revision operation for instability, three for recurrent dislocation and one for recurrent subluxation. Clinical and radiological comparisons with a matched group of stable total hips showed no correlation with demographic or radiological parameters.<\/jats:p>\n                  <jats:p>Patients with subluxing hips reported significantly more concern that their hip would dislocate, more often changed their behaviour to prevent instability and had lower postoperative Harris hip scores than patients with stable replacements.<\/jats:p>","DOI":"10.1302\/0301-620x.92b11.24702","type":"journal-article","created":{"date-parts":[[2010,10,31]],"date-time":"2010-10-31T20:08:19Z","timestamp":1288555699000},"page":"1522-1526","source":"Crossref","is-referenced-by-count":9,"title":["Transient subluxation of the femoral head after total hip replacement"],"prefix":"10.1302","volume":"92-B","author":[{"given":"B.
