Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Resection of bone from the head-neck junction will be performed using a burr, introduced into the hip joint via an arthroscopic procedure under the guidance of a combination of visual (camera), radiological (X-ray image intensifier) and computer-guided imaging modalities. The approximate duration of the procedure is 60-90 minutes.

Summary
Brief summary
Thus study aims to investigate new methods of treating a specific cause of hip pain, where the top of the thigh bone hits against the pelvic bone. Existing keyhole surgery techniques will be combined with a new computer-assisted method to determine if the surgery can be improved. Patients will be assessed before and after their operation to measure activity, pain and quality of life.
