Summary
Maisonneuve fractures often involve intra-articular lesions, particularly to the talar dome's medial section. Ankle arthroscopy effectively identified these associated injuries, aiding in Maisonneuve fracture management.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Maisonneuve fracture involves proximal fibular fracture with syndesmotic and medial ankle injuries.
- Outcomes vary, with some cases reporting poor results.
- Intra-articular lesions are a potential complication requiring investigation.
Purpose of the Study:
- To investigate the presence and nature of intra-articular lesions in Maisonneuve fractures.
- To evaluate the utility of arthroscopy in diagnosing these associated injuries.
Main Methods:
- Retrospective analysis of four Maisonneuve fracture cases undergoing surgical treatment.
- Ankle arthroscopy performed during surgery to assess tibiofibular syndesmosis, cartilage, and ligament damage.
- Articular cartilage lesions graded by depth.
Main Results:
- All four patients exhibited cartilaginous damage on the medial talar dome.
- No lateral talar dome lesions were observed.
- Tears of the anterior inferior tibiofibular and interosseous tibiofibular ligaments were consistently found; posterior ligament tears were absent.
- Chondral debris and hemarthrosis were common findings.
Conclusions:
- Arthroscopy is a valuable tool for identifying intra-articular lesions associated with Maisonneuve fractures.
- Medial talar dome cartilage damage is a frequent finding in these injuries.

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...
01:16Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
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...

01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

01:07Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:27Fractures: 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 procedure...
