Summary
Crossover second toe deformity predominantly affects women over 50. Key indicators include hallux valgus and specific joint angle deviations, aiding diagnosis.
Area of Science:
- Orthopedics
- Podiatry
- Foot and Ankle Surgery
Background:
- Crossover second toe deformity is a complex foot condition.
- Understanding its characteristics is crucial for effective treatment.
Purpose of the Study:
- To identify demographic factors, causes, and radiographic findings of crossover second toe deformity.
- To establish a baseline for future research and clinical practice.
Main Methods:
- Retrospective review of 169 patients undergoing surgery for crossover second toe deformity (2001-2006).
- Analysis of clinical data and radiographic measurements, including joint angles.
Main Results:
- The condition predominantly affects women (86%), with a mean age of 59.
- Hallux valgus and first metatarsophalangeal joint arthritis were common comorbidities.
- A positive drawer sign and medial angular deviation of the second metatarsophalangeal joint were significant findings.
Conclusions:
- Crossover second toe deformity is most prevalent in women over 50.
- Associated conditions include hallux valgus and degenerative arthritis of the first metatarsophalangeal joint.
- Radiographic assessment of the second metatarsophalangeal joint angle is key for diagnosis.

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
