This study will have implications for any healthcare professionals who routinely manage
ingrown toenails. Although different conservative and surgical treatment have been suggested,
the recurrent rate is still high ranging from 20% to 30%. The objective of this study was to
investigate the association of ingrown toenail (IGTN) with flat foot, hallux abducto valgus
(HAV) and hallux limitus (HL), and to provide directions for addressing biomechanical risk
factors in the prevention of recurrent ingrown toenails. This was the first study to
investigate the association of IGTN with flat foot, and the first study in Chinese community
to investigate the association of IGTN with HAV or HL.
Participants with ingrown toenails (IGTN) were recruited to this study and compared with
control participants with no history of ingrown toenails.
The inclusion criteria for the IGTN group were: (1) history of ingrown toenails on hallux
within 1 year and (2) dorso-plantar standing view of foot x-ray taken or to be taken.
The exclusion criteria for the IGTN group were: (1) paediatrics (Age<18), (2) pincer nails /
fungal nails, (3) prior existence of osteoarticular surgery in the foot, (4) severe trauma
that changes foot morphology, (5) uncontrolled systemic disease, (6) pre-existing
neurological diseases and (7) lower limb paralysis or paresis.
The inclusion criterion for the control group was dorso-plantar standing view of foot x-ray
taken or to be taken.
The exclusion criteria for the control group were: (1) all the exclusion criteria of IGTN
group, (2) history of IGTN in his or her lifetime and (3) flatfoot / first
metatarsophalangeal joint pathology as the chief complaint.
The symptomatic foot (or the more symptomatic foot in the case of bilateral involvement) in
the IGTN group was examined. The left or right foot of the control group was randomly
selected such that the ratio of the left or the right foot in the IGTN and control group was
the same.
Their foot posture index-6 components, Staheli's index, radiological hallux valgus angle and
active maximum dorsiflexion of the first metatarsophalangeal joint on weight-bearing were
measured and compared.
For dependent variables with significant correlation, a one-way multivariate analysis of
variance (MANOVA) was carried out to determine if there was a significant difference on the
combined dependent variables. For dependent variables without significant correlation,
separate independent sample t-tests / welch t-tests were performed.

Primary | Foot Posture Index-6 components | Clinical assessment for flat foot Normal: 0 to +5 Pronated: +5 to +9 ; Highly pronated: +10 or above Supinated: -1 to -4; Highly supinated: -5 to -12 |
throughout the study, within 1 year after ingrown toenails for the ingrown toenail group | |
Primary | Staheli's Index | It provides a measurement of flat foot on footprint. The Staheli's index increases as the foot becomes more pronated and is closer to zero as the foot becomes more supinated. |
throughout the study, within 1 year after ingrown toenails for the ingrown toenail group | |
Primary | radiological Hallux Valgus Angle | Radiological measurement for hallux abducto valgus Normal: <15º |
throughout the study, within 1 year after ingrown toenails for the ingrown toenail group | |
Primary | Active maximum dorsiflexion of the first metatarsophalangeal joint on weight bearing | Clinical measurement with goniometer for hallux limitus | throughout the study, within 1 year after ingrown toenails for the ingrown toenail group |
