Objective:

To introduce a method for accurate 3D osteotomy of cubitus varus deformity using a limited lateral incision, addressing the technical challenges in achieving accurate correction.

Key Findings:
  • Mean carrying angle improved from -15.74° to 7.77° postoperatively (p < 0.001).
  • Mean tilting angle improved from 54.8° to 51.4° (p < 0.05).
  • Elbow range of motion normalized with a mean increase in flexion angle of 24°.
  • Bone union achieved at a mean of 2.6 months.
  • Average operative time was 139.6 minutes with mean intraoperative blood loss of 42 mL.
  • All patients achieved excellent outcomes according to the Mayo Elbow Performance Index.
Interpretation:

Limitations:
  • Small sample size of five patients.
  • Retrospective evaluation may introduce bias.
  • Short follow-up duration for some patients.
Conclusion:
