Accurate prosthetic cup placement is very important in total hip arthroplasty (THA). When the surgeon is impacting the acetabular cup, it is assumed that the patient's pelvis is perpendicular to the operating table. In reality the pelvis may not be truly lateral, and error in patient positioning may influence the resultant cup orientation. The primary aim of this study was to examine the accuracy of patient positioning prior to THA. A secondary aim was to see if patient BMI influenced the accuracy of positioning.Introduction

Past research has focused on complications of bony fixation of navigation reference frames such as fractures and cutting errors. This study investigates the consequences of the use of iliac crest percutaneous navigational array pins in terms of pain, irritability and the impact on quality of life.Introduction
Objective
Leg length and offset are important considerations in total hip arthroplasty (THA). Navigation systems are capable of providing intra-operative measurements, which help guide the surgeon in leg length and offset adjustment. This controlled study investigates whether the use of computer navigation leads to more accurate achievement of pre-operative leg length and offset targets in THA.Introduction
Objective
Leg length and offset are important considerations in total hip arthroplasty (THA). Navigation systems are capable of providing intra-operative measurements of leg length and offset, and high accuracy has been shown in experimental studies. This Introduction
