Tibialis spastic varus foot without tarsal coalition: a report of two cases

Tibialis spastic varus foot without tarsal coalition: a case report

Tibialis spastic varus foot (TSVF) is an uncommon clinical entity primarily associated with tarsal coalition. This case report presents a rare instance of TSVF without tarsal coalition in an 8‑year-old male patient. Successful treatment was achieved through a conservative approach involving botulinum toxin injections and a plaster cast, highlighting the potential of nonsurgical interventions for this rare condition.

Tibial spastic varus foot caused by os calcaneus secundarius: A case report

Peroneal spastic flatfoot caused by tarsal coalition is well known; however, tibial spastic varus foot is a rare clinical entity also caused by tarsal coalition in most cases. The os calcaneus secundarius is a rare accessory bone between the anterior process of the calcaneus and the navicular bone. The case of a 29-year-old woman with tibial spastic varus foot caused by os calcaneus secundarius is presented. Operative excision of the os calcaneus secundarius completely resolved the varus deformity. This is the first case report involving tibial spastic varus foot caused by os calcaneus secundarius.

Tibialis Spastic Varus Foot With Calcaneonavicular Coalition: A Case Report and Review of the Literature

Peroneal spastic flat foot is a well-known condition usually occurring with tarsal coalition. Conversely, tibialis spastic varus foot is a rare condition, which can be difficult to diagnose. Moreover, tibialis spastic varus foot with calcaneonavicular coalition is extremely rare, with only a few published case reports. Resection of the calcaneonavicular bar is performed in the majority of patients. We report a case of tibialis spastic varus foot with calcaneonavicular coalition in an 11-year-old boy with intellectual disability. His family noticed his right varus foot deformity 1.5 years earlier. There was no obvious history of trauma. The deformity gradually worsened with running. Because conservative treatment failed, resection of the coalition was performed that facilitated a good outcome. In this article, we report our experience of tibialis spastic varus foot with calcaneonavicular coalition and review the English literature of this condition.
