The gait of patients with one resurfacing and one replacement hip: a single blinded controlled study.

Purposes: Post arthroplasty gait analysis has up till now been performed on subjects walking slowly on flat ground rather than challenging them at faster speeds or walking uphill. We therefore asked: (1) Is there a measurable difference in the performance of hip resurfacing arthroplasty (HRA) and total hip arthroplasty (THA) limbs at patients' self-determined fastest walking speeds and steepest inclines? and (2) Is there a relationship between the observed differences between the gait of HRA and THA implanted limbs and patient walking speeds and inclines.

Methods: In an ethically approved study we recruited patients with bilateral hip arthroplasties: one HRA and one THA.

An unusual hernia complication: a late presentation.

A 67-year-old man presented with a 10-year history of intermittent right iliac fossa pain. His only significant past medical history was an inguinal hernia repair 10 years ago. After investigations, the patient underwent a laparotomy.
