The treatment of chronic laxities of the ankle by external ligament tension restoration

---

Résumé

Chronic external laxities of ankle have long
been treated by plasties with the short peroneal as stabilizer
of the hindfoot. The restoration of the tension of the internal
external capsule–ligament complex with a subastragalus
Xap is an interesting solution. Thirty-two sporting
patients with an external instability of the ankle were
treated surgically by restoration of the tension of the external
lateral ligament using the Saragaglia technique and
were re-examined with an average 5-year time lag. The
instability and the anterior drawer were measured in pre
and post-operative periods. If the intervention gives good
results in severe external laxities, the result is deWnitely less
good in laxities of low importance. The presence of a functional
disorder of the forefoot constituted in the series a
pejorative factor. The intervention makes it possible to correct
external instability of the tibiotalar and subastragalus.
The conservation of the axis of the hindfoot is useful for a good performance because an instability of the subastragalus
deteriorates the result of the intervention.
