Neurovascular decompression for idiopathic tarsal tunnel syndrome: technical note

Abstract

Objective-The surgical outcome of idiopathic tarsal tunnel syndrome (TTS) is reported to be worse than that attributable to ganglion, tarsal coalition, or tumour, and therefore further development in the surgical treatment for idiopathic TTS is considered to be necessary. Here the eYcacy of neurovascular decompression for patients with idiopathic TTS is evaluated. Methods-Twelve feet from nine patients with idiopathic TTS were treated. The patients were aged 52-78 years (mean 64.6 years), and all of them complained of pain or dysaesthesia of the sole of the foot. The posterior tibial nerve was freed from the attached arteriovenous complex (posterior tibial artery and veins). The dissected nerve had a flattened appearance in all of the patients, suggesting nerve compression by the adjacent arteriovenous complex and superficially by the flexor retinaculum. A graft of fat was inserted as both a cushion and an antiadhesive between the vessels and the nerve to achieve neurovascular decompression. Results-Patients on whom neurovascular decompression was performed had resolution or lessening of symptoms in their feet. Neither wound infection nor recurrence of symptoms was found during the follow up period (mean 26.8 months). Conclusion-Neurovascular compression syndrome plays a part in idiopathic TTS, and adding neurovascular decompression to resection of the flexor retinaculum is eVective.

Tarsal tunnel syndrome associated with a perforating branch from posterior tibial artery: A case report

“…The posterior tibial neurovascular complexes are combined tightly in the tarsal tunnel because they are often attached to the fibrous septa with in the tunnel [14,15]. In the present case, possibly the medial plantar portion of tibial nerve was penetrated by a branch of posterior tibial artery.…”

Resultados do tratamento cirúrgico da síndrome do túnel do tarso posterior idiopática

“…Kohno e cols. 13 , em 2000, sugeriram a existência da compressão neurovascular na síndrome do túnel do tarso idiopática e, devido a isso, reportaram uma técnica de interposição de fragmento de tecido gorduroso entre os nervos e as veias. Na presente série, considerando esta possibilidade, o autor preferiu a coagulação e secção das veias que cruzavam o trajeto nervoso.…”

Ergonomic Pain––Part 2: Differential Diagnosis and Management Considerations

“…Invasive procedures can include injections at the tarsal tunnel and sympathetic ganglion blocks. As a last resort, surgical release of the tunnel retinaculum can be implemented, 237 where the technique can be improved when using an insertion of a fat graft between the vessels and the tibial nerve 238 …”
