چکیده

AIM To present the functional and radiological results and evaluate the effectiveness of a computer-assisted external fixator (spider frame) in patients with lower extremity shortness and deformity. MATERIALS AND METHODS The study comprised 17 patients (14 male, 3 female) who were treated for lower extremity long bone deformity and shortness between 2012 and 2015 using a spider frame. The procedure's level of difficulty was determined preoperatively using the Paley Scale. Postoperatively, the results for the patients who underwent tibial operations were evaluated using the Paley criteria modified by ASAMI, and the results for the patients who underwent femoral operations were evaluated according to the Paley scoring system. The evaluations were made by calculating the External Fixator and Distraction indexes. RESULTS The mean age of the patients was 24.58 years (range, 5-51 years). The spider frame was applied to the femur in 10 patients and to the tibia in seven. The mean follow-up period was 15 months (range, 6-31 months) from the operation day, and the mean amount of lengthening was 3.0 cm (range, 1-6 cm). The mean duration of fixator application was 202.7 days (range, 104-300 days). The mean External Fixator Index was 98 days/cm (range, 42-265 days/cm). The mean Distraction Index was 10.49 days/cm (range, 10-14 days/cm). CONCLUSION The computer-assisted external fixator system (spider frame) achieves single-stage correction in cases of both deformity and shortness. The system can be applied easily, and because of its high-tech software, it offers the possibility of postoperative treatment of the deformity.

Limb lengthening and correction of deformity in the lower limbs of children with osteogenesis imperfecta.

We performed limb lengthening and correction of deformity of nine long bones of the lower limb in six children (mean age, 14.7 years) with osteogenesis imperfecta (OI). All had femoral lengthening and three also had ipsilateral tibial lengthening. Angular deformities were corrected simultaneously. Five limb segments were treated using a monolateral external fixator and four with the Ilizarov fr...

Correction of Tibial Malunion in a Patient with Ipsilateral Total Knee and Ankle Prostheses Using External Ring Fixation and the Ilizarov Method Case Report

Bone, joint, and soft‐tissue deformities of the lower limb have been shown to influence the integrity of ipsilateral joints.[1‐3] For example, increased varus/valgus deformity of an arthritic ankle has been associated with increased arthritis in the ipsilateral knee.[1] One study showed that in patients with varus knee and valgus hindfoot deformities, correction of knee alignment with total kne...
