Abstract
Introduction
To achieve tibiotalocalcaneal arthodesis, implants described range from external fixator, compression screws and anterior plate and the more recent retrograde calcaneal locked intramedullary nail. Our aim is to assess the outcome of the AO cannulated blade plate for tibiotalocalcaneal arthrodesis.
Patients and methods
Four tibiotalocalcaneal arthrodeses were performed in three patients. The operative technique involves lateral approach to the distal fibula that was osteotomised and used as bone graft. The articular cartilage of ankle and subtalar joint was removed using an osteotome and congruent surfaces achieved. AO cannulated blade plate was applied on the lateral aspect to achieve compression. The postoperative protocol included a plaster cast for three months, followed by mobilization out of plaster.
Results and discussion
At the mean follow up of 10 months (range five to fourteen months) all patients were pain free on full weight bearing. The union was achieved at three months which was confirmed clinically and radiologically. There was no infection, wound breakdown, or loss of position at the ankle or subtalar joints. Mean preoperative American Orthopaedic Foot and Ankle Society ankle/hindfoot score was 21 and postoperative score 83. We conclude that the cannulated blade plate is an alternate technique for tibiotalocalcaneal arthodesis, with no moulding of the implant required to attain satisfactory alignment.
