Summary
This study compared one-stage and gradual lengthening for brachymetatarsal rays, finding gradual lengthening achieved greater length gain. Combining bone shortening with lengthening improved outcomes and reduced complications in foot surgery.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
- Skeletal Reconstruction
Background:
- Brachymetatarsal rays present a challenge in foot length discrepancy.
- Surgical correction aims to restore foot anatomy and function.
Purpose of the Study:
- To evaluate the efficacy of one-stage lengthening versus gradual lengthening (callotasis) for brachymetatarsal rays.
- To assess the impact of associated bone shortening on surgical outcomes.
Main Methods:
- Treatment of 35 brachymetatarsal rays in 12 patients using either one-stage lengthening with bone grafts or gradual lengthening with callotasis.
- Inclusion of adjacent bone shortening (metatarsals/phalanges) in some cases.
- Utilized parabolic curves and metatarsal length patterns to guide treatment.
Main Results:
- Gradual lengthening yielded a greater mean length gain (2.0 cm, 50% increase) compared to one-stage lengthening (1.3 cm, 30% increase).
- Healing index was 1.3 months/cm for one-stage and 2.0 months/cm for gradual lengthening.
- Associated shortening of adjacent bones mitigated risks of inadequate length gain and neurovascular complications associated with one-stage lengthening.
Conclusions:
- Gradual lengthening with callotasis provides superior length gain for brachymetatarsal rays.
- Combining bone shortening with lengthening techniques can improve surgical results, reduce treatment duration, and enhance cosmetic outcomes.
