It is also common in older adults, as age-related changes in foot structure and muscle strength can contribute to the development of this deformity[1].
• Risk Factors: Individuals with a history of foot injuries, certain neurological conditions, or those with a family history of foot deformities are at higher risk. Additionally, conditions such as diabetes and rheumatoid arthritis can predispose individuals to develop hammer toes[2].

Signs and Symptoms

Physical Examination Findings

• Toe Deformity: The most noticeable sign is the bending of the toe at the proximal interphalangeal joint, which may be rigid or flexible. The affected toe may appear claw-like, with the tip pointing downward and the middle joint raised[3].
• Swelling and Redness: Inflammation may occur around the affected joint, leading to swelling and redness, particularly if the condition is exacerbated by ill-fitting shoes[4].
• Calluses and Corns: Due to abnormal pressure on the toe, calluses or corns may develop on the top of the toe or on the ball of the foot, where the toe rubs against the shoe[5].

Symptoms Reported by Patients

• Pain and Discomfort: Patients often report pain in the affected toe, especially when wearing shoes. The pain may be sharp or aching and can worsen with activity[6].
• Difficulty Walking: The deformity can lead to altered gait mechanics, making walking uncomfortable or difficult. Patients may compensate by changing their walking patterns, which can lead to additional foot or leg pain[7].
• Numbness or Tingling: Some patients may experience numbness or tingling in the affected toe or surrounding areas, particularly if there is nerve compression due to the deformity[8].

Patient Characteristics

Medical History

• Previous Foot Problems: A history of foot problems, such as bunions or other toe deformities, can be common among patients with hammer toes[9].
• Chronic Conditions: Patients with chronic conditions like diabetes or arthritis may have a higher incidence of hammer toe due to changes in foot structure and function over time[10].

Lifestyle Factors

• Footwear Choices: Many patients report wearing tight or high-heeled shoes, which can contribute to the development of hammer toes. Education on proper footwear is often a key component of management[11].
• Activity Level: Active individuals, particularly those involved in sports that place stress on the feet, may be more susceptible to developing this condition due to repetitive trauma or pressure on the toes[12].
