Abstract

In cycling, pedalling symmetry and foot position is paramount for an energy efficient and injury free ride. Traditionally a clipped pedal was used to secure the foot onto the pedal, which was found to be related to a number of overuse knee injuries, leading to the advent of clipless pedals or cleats, which allowed for a more efficient pedal stroke.

Summary

Introduction

There are three contact points between a body and a bike during cycling: the handle bars, the saddle and the pedals. A 54 year old lady, with past history of successfully treated breast carcinoma, presented with a right transcervical neck of femur fracture following her cleat injury. This was successfully managed with cannulated screws with no long term problems on follow-up (Figure 1a and Figure 1b). A 64 year old male presented with a transverse impacted left neck of femur fracture following cleat failure whilst cycling. He underwent a successful total hip replacement with no post-operative complications. Figure 3d: Anteroposterior left ankle x-ray view of further subluxation following failed revision surgery
