Introduction:
A patient with medial ankle osteoarthritis and a widened ankle mortise can be treated successfully with an oblique distal tibial osteotomy, without fibular osteotomy, to narrow the mortise and shift the weight-bearing axis to a more normal position.
Step 1 Patient Positioning And Preoperative Assessment:
With the patient under spinal or general anesthesia, check for mortise widening with a valgus stress test.
Step 2 Surgical Approach:
Expose the ankle joint through an anterior approach.
Step 3 Corrective Osteotomy:
Perform an oblique osteotomy of the distal part of the tibia and narrow the widened mortise by shifting the osteotomized fragment.
Step 4 Fixation And Bone-Grafting:
Stabilize the osteotomy site with a locking plate and apply bone graft to the osteotomy site.
Step 5 Closure:
Close the soft tissue in layers.
Results:
Eighteen patients (fifteen female and three male; mean age, fifty-seven years) with symptomatic medial ankle osteoarthritis and mortise widening underwent distal tibial oblique osteotomy without fibular osteotomy between 2008 and 2011.IndicationsContraindicationsPitfalls & Challenges.
