Clinical Report: Customized 3D-Printed Osteotomy Guides for Cubitus Varus Deformity

Overview

This study evaluates the use of 3D-printed osteotomy guides for correcting cubitus varus deformity. Significant improvements in carrying angles and elbow function were observed postoperatively, with a low complication rate.

Background

Cubitus varus deformity is a common complication following supracondylar fractures, characterized by complex three-dimensional malalignment. Accurate correction is essential to prevent long-term complications such as limited elbow flexion and joint instability. Recent advances in 3D printing technology offer potential solutions for achieving precise surgical corrections.

Data Highlights

ParameterPreoperativePostoperative
Carrying Angle (°)-15.74 ± 6.587.77 ± 3.94
Tilting Angle (°)54.8 ± 7.4051.4 ± 2.33
Flexion Angle Increase (°)N/A24 ± 8
Bone Union Time (months)N/A2.6 ± 0.49
Operative Time (min)N/A139.6 ± 22.26
Intraoperative Blood Loss (mL)N/A42 ± 31.87

Key Findings

  • The mean carrying angle improved from -15.74° to 7.77° postoperatively.
  • All patients normalized their elbow range of motion with a mean increase in flexion of 24°.
  • Bone union was achieved at a mean of 2.6 months.
  • The average operative time was 139.6 minutes with minimal intraoperative blood loss.
  • All patients achieved excellent outcomes according to the Mayo Elbow Performance Index.
  • One patient experienced transient ulnar nerve symptoms postoperatively.

Clinical Implications

The use of 3D-printed, patient-specific osteotomy guides may enhance surgical precision in correcting cubitus varus deformity. This technique could potentially reduce variability in surgical outcomes and improve recovery times.

Conclusion

The study demonstrates that 3D-printed osteotomy guides facilitate safe and accurate correction of cubitus varus deformity through a limited incision, representing a promising approach in orthopedic surgery.
