Summary
This study shows that improved bilateral tibia lengthening effectively increases limb length with a high patient satisfaction rate. The technique offers a shorter bone union time and fewer complications, also correcting varus knee deformities.
Area of Science:
- Orthopedic surgery
- Limb reconstruction surgery
Background:
- Low stature affects patient quality of life.
- Bilateral tibia lengthening is a surgical option for height increase.
Observation:
- A modified bilateral tibia lengthening technique was applied to 32 patients (18-45 years old) with low stature.
- The procedure involved tibia and fibula osteotomy, fixation with interlocking nails, and a lengthening apparatus.
- Limb lengthening was performed at a rate of 0.7 mm per day.
Findings:
- The mean lengthening achieved was 8.5 cm over a mean duration of 128 days.
- Mean bone union time was 180 days, with 98% of patients reporting satisfactory outcomes in lengthening, gait, and joint movement after 1-3 years.
- The technique successfully corrected varus knee deformities in 8 cases.
Implications:
- The improved bilateral tibia lengthening technique is a viable option for limb lengthening.
- This method demonstrates advantages in reduced bone union time and complication rates.
- Simultaneous correction of varus knee deformity is a significant benefit of this surgical approach.
