Summary
Distraction callotasis effectively lengthened digits after traumatic amputation. Healing was faster when complications like poor callus formation were avoided, with proximal metaphysis osteotomies yielding better outcomes.
Area of Science:
- Orthopedic surgery
- Regenerative medicine
Background:
- Traumatic amputation of digits often leads to functional and aesthetic deficits.
- Limb lengthening techniques, such as distraction callotasis, offer a reconstructive option for digit loss.
Purpose of the Study:
- To evaluate the clinical outcomes of digit lengthening using distraction callotasis.
- To identify factors influencing healing and success rates in this patient cohort.
Main Methods:
- Retrospective analysis of 26 digits (18 patients) undergoing distraction callotasis for traumatic amputation.
- Evaluation of osteotomy site, complications, bone grafting requirements, and healing rates (days/cm).
Main Results:
- Successful lengthening was achieved in 23 of 26 digits, with five requiring bone grafts.
- Digits without complications healed at 96 days/cm, compared to 158 days/cm with complications.
- Lengthening at the proximal metaphysis showed superior results compared to diaphyseal or distal metaphyseal sites.
Conclusions:
- Distraction callotasis is a viable technique for digit lengthening after traumatic amputation.
- Minimizing complications and selecting appropriate osteotomy sites, particularly the proximal metaphysis, are crucial for optimal healing and functional recovery.
