Summary
Coronal malalignment, specifically metatarsal pronation, is common in hallux valgus and can lead to deformity relapse after surgery. Identifying and correcting this rotational issue is key for successful hallux valgus treatment.
Area of Science:
- Orthopedics
- Podiatry
- Foot and Ankle Surgery
Background:
- Coronal malalignment, particularly metatarsal pronation, is a significant deformity in hallux valgus.
- Approximately 90% of hallux valgus patients exhibit some degree of metatarsal pronation.
- Persistent metatarsal pronation post-surgery is a known factor for hallux valgus deformity recurrence.
Purpose of the Study:
- To highlight the importance of coronal malalignment in hallux valgus.
- To discuss methods for identifying metatarsal pronation.
- To review surgical techniques capable of correcting rotational deformities in hallux valgus.
Main Methods:
- Identification of coronal malalignment using anteroposterior (AP) weight-bearing foot radiographs.
- Assessment of metatarsal pronation levels (mild, moderate, severe) via AP foot views.
- Review of surgical techniques addressing rotational correction.
Main Results:
- Coronal malalignment is a key parameter in hallux valgus.
- Metatarsal pronation is prevalent in hallux valgus patients and a relapse factor.
- AP weight-bearing foot radiographs and forefoot scans aid in identifying malalignment.
Conclusions:
- Coronal malalignment and metatarsal pronation are critical considerations in hallux valgus.
- Accurate identification of pronation is achievable through radiographic and scanning methods.
- Several surgical techniques offer potential for rotational correction in hallux valgus treatment.
