Digital Technology-Assisted "Z" Osteotomy lower limb corrective procedures

Area of Science:

• Orthopedic surgery
• Digital technology in medicine
• Limb deformity correction

Background:

• Digital technology offers transformative solutions in medicine.
• Z-osteotomy is a surgical technique for limb angulation and length correction.
• Lower limb deformities require precise surgical intervention.

Purpose of the Study:

• To introduce digitally assisted Z-osteotomy for lower limb deformities.
• To investigate the clinical efficacy of this digital technique.
• To assess computer-assisted planning and 3D-printed guides in orthopedic procedures.

Main Methods:

• Retrospective study of five patients with multiplanar lower extremity deformities and shortening.
• Utilized computer-assisted preoperative design and 3D-printed surgical guides.
• Compared pre- and post-operative parameters including deformities, limb length, and functional scores.

Main Results:

• Follow-up of 17.20±6.83 months showed adequate correction of deformities.
• Significant improvement in the modified Barthel Index (90±3.08 points, P<0.05).
• One patient experienced transient wound pain; four cases had no complications.

Conclusions:

• Digitally assisted Z-osteotomy demonstrates remarkable clinical results for complex lower limb deformities.
• The technique accurately corrects multi-planar angular deformities and achieves limb lengthening.
• This method is safe, reliable, and improves patient self-care ability.
