Summary
A detachable focused rigidity cast effectively treats tuberosity fractures of the proximal fifth metatarsal. However, Jones and diaphyseal fractures require orthopedic referral for optimal management.
Area of Science:
- Orthopedics
- Traumatology
- Podiatric Surgery
Background:
- Proximal fifth metatarsal fractures, including tuberosity and Jones fractures, are common foot injuries.
- Current treatment strategies vary, necessitating evaluation of novel, non-invasive approaches.
Purpose of the Study:
- To evaluate the efficacy of a detachable focused rigidity cast as a single definitive treatment for proximal fifth metatarsal fractures.
- To compare treatment outcomes for tuberosity versus Jones fractures using this casting method.
Main Methods:
- A prospective trial conducted over two years included 41 patients with proximal fifth metatarsal fractures.
- Patients were treated with a detachable focused rigidity cast, with follow-up assessments for clinical union and complications.
Main Results:
- All 33 patients with tuberosity fractures achieved clinical union within 4-5 weeks (mean 4.2 weeks).
- Of six Jones fractures, four united in 8-12 weeks, one in 14 weeks, and one required surgical intervention for delayed union.
- No cast-related complications were reported.
Conclusions:
- The detachable focused rigidity cast is a suitable one-off treatment for tuberosity fractures of the fifth metatarsal.
- Jones and diaphyseal fractures of the fifth metatarsal necessitate referral to an orthopedic specialist for further management.
