The effect of hallux valgus on the anatomy of the
nerves around the first metatarsal bone: Does the
valgus deviation affect the location of the nerves?
Fatih Çiçek et al
Research Square

Objective
To identify the variations in the position and distribution of the nerves that may be at risk in surgical
approaches to hallux valgus (HV), and to reveal whether these nerves are affected by the anatomical
changes associated with HV.
Method
In the formalin fixed 46 lower extremities (19 female, 27 male), extensor hallucis longus tendon (EHL),
deep plantar artery, medial dorsal cutaneous (MDCN), deep fibular (DFN), common plantar digital (CPDN)
and proper plantar digital (PPDN) nerves were examined. The branches of MDCN extending to the medial
side of foot were recorded in three segments. The positional topography of nerves according to EHL were
analysed on 360° circle and clock models.
Results
Gender-related differences for some parameters in direct measurements were not found in comparisons
on the clock model. In HV cases, DFN was closer to EHL in the distal part of the metatarsal bone, while
there was no difference in the proximal and the intersection of the medial branch of the MDCN with the
EHL was more proximal. The location of the nerves in the clock pattern did not change in HV cases. Of
the nerve branches reaching the medial side of the foot, 65.2% were in Part I, 71.7% in Part II, and 4.3% in
Part III.
Conclusion
It was revealed that the gender differences in the distance of the nerves to the EHL disappeared when the
size effect of the cross-section of the first metatarsal bone region was eliminated with the clock model.
No evidence was found that the location of the nerves around the proximal metatarsal is affected by HV.
However, in advanced HV levels, the DFN was found distally closer to the EHL, and the intersection of the
medial branch of the MDCN with the EHL was more proximal. The variations we revealed in the number
of branches reaching the inside of the foot may explain the diversity of neuromas or nerve injuries
associated with hallux valgus surgery.
