Aim:
The aim of the study was to analyze the biomechanical effects of flexible claw toe correction by tendon transfer with the Girdlestone-Taylor approach using dynamic pedobarography.
Material And Methods:
In the study 12 patients were examined preoperatively and 12 months postoperatively. The results obtained by pedobarography 12 months postoperatively were compared with those of a healthy control group of matched age and body mass index (BMI). For clinical evaluation the American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue pain scale (VAS) were evaluated.
Results:
The results showed a significant increase in the average AOFAS score from 72 (range 63-79) preoperatively to 92 (84-96) points 12 months postoperatively. The pedobarography revealed significantly increased values in the force-time integral and the maximum force for the second and third toes 12 months postoperatively. Compared with preoperative measurement values a significantly increased peak pressure could be assessed for the third toe only. It is assumed that the combination of functional arthrodesis of the proximal interphalangeal (PIP) joint and the strain shift by tendon transfer causes this increase in peak pressure.
Conclusion:
Atter Girdlestone-Taylor tendon transfer reestablishment of floor contact of flexible claw toes could be demonstrated by dynamic pedobarography.
