Ankle Joint

Ankle 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...

Muscles of the Leg that Move the Foot and Toes

Muscles 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....

Bones of the Lower Limb: Tibia and Fibula

Bones 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...

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Maisonneuve-hyperplantarflexion variant ankle fracture.

Richard M Hinds, Wesley H Tran, Dean G Lorich

|November 1, 2014

Summary

This study reports a rare combined Maisonneuve and hyperplantarflexion variant ankle fracture. Open reduction and internal fixation (ORIF) of both tibial fragments yielded good results, with MRI aiding diagnosis.

Area of Science:

Orthopedic Surgery
Radiology
Traumatology

Background:

Maisonneuve fractures involve proximal fibula, syndesmotic, and medial ankle injuries.
Hyperplantarflexion variant fractures feature dual posterior tibial lip fractures.
Both are distinct ankle fracture patterns with specific management protocols.

Observation:

A unique case presented with combined Maisonneuve and hyperplantarflexion variant ankle fracture characteristics.
Diagnostic imaging, including MRI and radiographs, was crucial for identifying the fracture pattern.
The patient underwent surgical treatment addressing both fracture components.

Findings:

Open reduction and internal fixation (ORIF) of both posteromedial and posterolateral tibial fragments was performed.
