Summary
Markers on a horse's tuber coxae reveal hindlimb lameness. The lame side consistently shows increased vertical movement and a distinct stride pattern, aiding diagnosis in teaching and research.
Area of Science:
- Equine biomechanics
- Veterinary orthopedics
Background:
- Assessing hindlimb lameness in horses is crucial for welfare and performance.
- Understanding the tuber coxae's movement provides insights into equine locomotion.
Purpose of the Study:
- To describe a method using markers on the tuber coxae to identify relative movement during trot.
- To investigate the diagnostic potential of tuber coxae movement patterns in hindlimb lameness.
Main Methods:
- Markers were placed bilaterally over the tuber coxae of horses.
- Relative vertical displacement and movement patterns of the tuber coxae were analyzed during trot.
- Horses with induced or naturally occurring hindlimb lameness were studied.
Main Results:
- A consistent increase in vertical displacement of the tuber coxae was observed on the lame side compared to the contralateral limb.
- A characteristic movement pattern of the tuber coxae throughout the stride was identified in lame horses.
- These findings were independent of the lameness location or etiology.
Conclusions:
- Marker-based analysis of tuber coxae movement is a valuable tool for identifying and characterizing hindlimb lameness in horses.
- The observed changes in tuber coxae dynamics offer a reliable indicator for lameness diagnosis in equine studies and teaching.
