Abstract

PURPOSE
To compare the clinical results of spontaneous rupture of extensor pollicis longus tendon treated by palmaris longus tendon graft (group I) versus extensor indicis proprius tendon transfer (group II).
MATERIALS AND METHODS
Out of twenty-five patients who suffer from spontaneous extensor pollicis longus tendon rupture, twelve patients were treated by palmaris longus tendon graft and thirteen patients were treated by extensor indicis proprius tendon transfer. Postoperatively thumbs were immobilized with thumb spica splint for three weeks. Active and passive movement was allowed subsequently for six weeks. The functions of the thumbs were assessed by the Geldmacher criteria and statistically compared.
RESULTS
The overall outcome was excellent in 5(20%) of patients and good in 17(68%) of patients and satisfactory in 3(12%) of patients. The mean scores using the Geldmacher criteria were 18.50 for palmaris longus tendon graft and 19.69 for extensor indicis proprius tendon transfer. No significant difference was noted between two groups.
CONCLUSION
Both methods establish equally good clinical results in patient with chronic extensor pollicis longus tendon rupture. Extensor indicis proprius tendon transfer seems more available methods.
