Osteotomy of the tibia for correction of complex deformity

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Deformity Correction

Background:

• Anterior poliomyelitis can cause complex tibial deformities.
• These deformities often affect multiple planes, including rotation, valgus, and flexion.
• Surgical correction is necessary to restore function and alignment.

Purpose of the Study:

• To evaluate the efficacy of a modified O'Donoghue osteotomy for correcting complex tibial deformities.
• To assess the technique's ability to address multi-planar deformities.
• To determine the safety and long-term outcomes of this surgical approach.

Main Methods:

• A modified O'Donoghue osteotomy was performed on 20 complex tibial deformities in 18 patients.
• The technique involved widening a rectangular window distally and trimming anterior step cuts.
• An above-knee cast was applied for 8-13 weeks, with a mean follow-up of 3.2 years.

Main Results:

• Excellent correction of three-plane deformities (rotation, valgus, flexion) was achieved.
• No recurrence of deformity was observed during the follow-up period.
• One patient experienced delayed union due to a fracture of the medial limb of the step cut.

Conclusions:

• The modified O'Donoghue osteotomy is a safe and effective procedure for correcting complex tibial deformities.
• This technique allows for simultaneous correction of torsional and angular deformities in multiple planes.
• The procedure does not require internal fixation, simplifying the surgical process.
