Lower limb deformity correction using Ortho-SUV frame in skeletally mature patients

Background
Gradual correction of lower limb deformity using the Ilizarov apparatus is an established method. The Ortho-SUV frame is a computer-assisted system that simultaneously allows accurate and timely correction of various deformities.


Patients and methods
This prospective study included 13 patients with various lower limb deformities (femur and tibia) treated with an Ortho-SUV frame in one center between October 2020 and December 2023.


Results
The correction time ranged from 3 to 49 days. Correction accuracy was full in 12 (92.31%) patients and residual 10 degrees of plantar flexion in one (7.69%) patient. The number of schedules for correction was one in four (30.77%) patients, two in eight (61.54%) patients, and three in one (7.69%) patients. The union time ranged from 79 to 285 days, with a mean of 154.3 (±60.9). The time in frame ranged from 81 to 362 with a mean of 204 (±86.37). The follow-up duration ranged from 5.8 to 38.17 months, with a mean of 24.59 (±11.05).


Conclusion
Lower limb deformity correction using the Ortho-SUV resulted in the accurate correction of simultaneous deformities.
