Summary
Distal tibiofibular synostosis after ankle fracture surgery typically results in minimal symptoms and requires no specific intervention. Ankle function is generally well-preserved, with normal gait observed in affected patients.
Area of Science:
- Orthopedic Surgery
- Biomechanics
Background:
- Distal tibiofibular synostosis can be a complication following surgical treatment for ankle or distal tibia/fibula fractures.
- Understanding its impact on ankle function is crucial for patient management.
Purpose of the Study:
- To investigate the functional consequences of distal tibiofibular synostosis after operative fracture treatment.
- To evaluate the long-term outcomes and necessity of treatment for this condition.
Main Methods:
- A cohort of 281 patients undergoing surgery for ankle or distal tibia/fibula fractures between 1998 and 2004 was reviewed.
- Eight patients developed distal tibiofibular synostosis post-operatively and were followed for an average of 20.6 months.
- Ankle function was assessed using Mazur's functional rating system.
Main Results:
- Functional outcomes included 4 excellent, 2 good, and 2 fair results based on Mazur's system.
- A mean reduction in dorsiflexion of 8.26 degrees was noted in the affected ankles compared to the contralateral side.
- Plantar flexion showed minimal impact, and all patients maintained a normal gait.
Conclusions:
- Distal tibiofibular synostosis post-surgery for ankle and distal tibia/fibula fractures is generally asymptomatic.
- The condition typically does not necessitate specific treatment due to minimal functional impairment.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
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...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
