One such activity is retrieving an object from the floor. The aim of this study was to assess hip movement using four different techniques to accomplish this task. This assessment would identify the techniques least likely to cause a hip dislocation. Methods An electromagnetic tracker was used to measure the movement of 50 hips in 25 normal subjects. Sensors were attached over the iliac crest and the mid-shaft of the lateral thigh. Data was then collected for 3 repetitions of each of the following retrieval techniques - 1. Flexing forward to pick up an object between the feet. 2. Flexing to pick up an object lateral to the foot. 3. Squatting to pick up an object between the feet. 4. Kneeling on one knee to pick up beside the knee. Results Kneeling required a mean movement of degree s flexion and degree s external rotation. This was significantly less than all the other techniques paired t-test P . Squatting required degree s flexion and degree s internal rotation. Conclusion The study showed that squatting had the most flexion and internal rotation whereas kneeling has the least flexion. Thus to minimise the dislocation risk when retrieving an object from the floor kneeling should be adopted and squatting should be avoided. Background Total Hip replacements significantly improve the quality of life indices with most patients returning to normal activities within 6 weeks 1 . However 2 to 11 2 of patients experience a post-operative dislocation. An initial dislocation may lead to recurrent dislocations
