Data Trace Editor – Thumb MP Joint: Tension Band Technique: – needs to be fused in 10-20 deg flexion, 20 deg pronation, and 20 deg of abduction; – tension band can neutralize the distraction force of the finger flexors (which are stronger than extensors and therefore cause distraction); – dorsal incision is … Read more
– Discussion: – this is probably an under rated procedure in terms of its indications; – surgical indications: – hallux valgus + 2nd toe amputation: – great toe is stabilized in part by the presence of 2nd toe; – when it is absent, a hallux valgus valgus deformity is best treated by arthrodesis of first … Read more
