Endoscopy-Assisted Minimally Invasive Calcaneus Osteotomy in Calcaneus Malunion Surgery

Calcaneal malunion, one of the late complications of calcaneal fractures, refers to residual bone malalignment often associated with pain and deformity due to inadequate conservative or inadequate/unsuccessful surgical treatment. Complications associated with calcaneal fractures can be treated either arthroscopically or endoscopically. We aimed to analyze a case in which we performed endoscopy-assisted, minimally invasive calcaneal osteotomy after endoscopic flexor hallucis longus tendon release. We investigate the surgical technique used in a patient with flexor hallucis longus compression caused by osteophytes posterior to the subtalar joint following calcaneal malunion, who presented with difficulty wearing shoes associated with loss of calcaneal height.
