Summary

Motion sensors will be used in long bone deformity surgery in pediatric patients. In patients whose deformity status is determined before the surgery, 2 wires will be placed in the same plane from the proximal and distal of the determined osteotomy line to the long bones of the patients who are anesthetized during the surgery and motion sensors will be placed on the wires. Osteotomy will be performed on the bone with deformity from the deformity center. While correcting the degree of deformity, fixation with plate and screws will be performed after the amount of correction determined preoperatively is achieved. Thanks to the sensors and application, it will be determined exactly how many degrees of deformity will be corrected in the case. At the same time, multiplanar and difficult-to-detect deformities will be corrected almost ideally with the help of motion and acceleration sensors. Approximately at the 6th week after the case, deformity correction status will be recorded again with gait analysis and physical examination following the removal of the cast, splint and bone healing. The results will be compared after the traditional method and the method using sensors are performed with an equal number of patients. As a result, it is aimed to clearly correct the deformity quantitatively and shorten the surgical time.

Detailed description

Patients who are between the ages of 2 and 18, who are admitted to Atatürk University Faculty of Medicine Research Hospital, who are considered to have long bone deformities in their lower extremities and who have gait disorders and who have not previously undergone lower extremity surgery, will be included in the study. To determine the degree of preoperative deformity of these patients, a physical examination will be performed after gait analysis and foot advancement angles, hip rotation degrees, thigh foot angles, transmalleolar axis angles and forefoot alignment will be determined and recorded. Following the routine preoperative computerized tomography performed on the patients, long bone alignment disorders, joint incompatibilities (valgus, varus deformities), femoral anteversion, femoral retroversion, tibial torsion angles will be determined quantitatively, and the amount of deformity correction to be performed in the surgery will be determined before the surgery and the quantitative values will be recorded. After two wires are placed in the same plane from the proximal and distal parts of the determined osteotomy line, motion sensors will be placed on the long bones of the anesthetized patients during the surgery. Osteotomy will be performed on the bone with deformity from the deformity center. When correcting the degree of deformity, fixation with plate and screws will be performed after the correction is achieved by the amount of deformity determined preoperatively. (In other countries and in our country, approximate correction is provided without quantitative data. Although the preoperative degree of deformity can be determined quantitatively, surgery is performed by determining the degree of correction intraoperatively by eye decision.) Thanks to the sensors and application, exactly how many degrees of deformity will be corrected will be determined in the case. At the same time, multiplanar and difficult-to-detect deformities will be corrected almost ideally with the help of motion and acceleration sensors. Approximately at the 6th week after the case, deformity correction status will be recorded again with gait analysis and physical examination following the removal of the cast, splint and bone healing.

Conditions

• Angulation Deformity of Long Bone (Disorder)
• Acquired Deformity of Knee Joint (Disorder)

Interventions

Type	Name	Description
OTHER	Group using traditional method in long bone deformity correction	Osteotomy will be performed from the deformity center after two coring wires are placed in the same plane from the proximal and distal of the determined osteotomy line to the femur or tibia of the patients in the control group with deformity. While the degree of deformity is corrected, the determination will be made after the amount of deformity determined preoperatively is determined visually.
DEVICE	Group using computer-aided sensors in long bone deformity correction	After 2 wires are placed in the same plane from the proximal and distal parts of the osteotomy line determined on the deformed femur or tibia of patients who underwent general anesthesia during the surgery, motion sensors will be placed on the wires. Osteotomy will be performed on the bone with deformity from the deformity center. When correcting the degree of deformity, the detection will be performed after the correction is achieved by the amount of deformity determined preoperatively.
