Second Toe Length and Hallux Valgus: Greek vs. Egyptian Foot

Greek vs. Egyptian Foot: The Impact of Second Toe Length on Hallux Valgus Development

A total of 150 patients aged 60-80 years with existing foot radiographs will be included in the study. Radiographic evaluations will include measurements of the hallux valgus angle, first intermetatarsal angle, and the metatarsal and phalanx lengths of the first and second toes. The ratio of the second toe phalanx length to the first toe phalanx length will be calculated and recorded. The relationship between the hallux valgus angle, toe lengths, and their ratios will be analyzed using statistical methods.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hallux Valgus Angle	The angle between the first metatarsal and the proximal phalanx of the first toe, measured on radiographs. Higher values indicate greater hallux valgus severity.	0 day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
First Intermetatarsal Angle	The angle between the first and second metatarsal bones, measured on radiographs. Higher values are associated with increased deformity.	0 day
First Toe (Hallux) Metatarsal and Phalanx Lengths	The length of the first metatarsal and its phalanges, measured on radiographs.	0 day
Second Toe Metatarsal and Phalanx Lengths	The length of the second metatarsal and its phalanges, measured on radiographs.	0 day
Second Toe to First Toe Phalanx Length Ratio	The ratio of the second toe phalanx length to the first toe phalanx length, calculated to assess relative toe length differences.	0 day
