Summary
Minimally invasive distal tibia fracture fixation requires careful consideration of nearby anatomy. Key anterior structures, including neurovascular bundles, are critically close to the tibial cortex, necessitating precise surgical technique.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Radiology
Background:
- Minimally invasive plating techniques for distal tibia fractures are established but carry risks.
- Understanding the precise anatomical relationships around the distal tibia is crucial for safe surgical fixation.
Purpose of the Study:
- To provide a detailed magnetic resonance imaging (MRI)-based anatomical description of the distal tibia.
- To quantify the proximity of critical anterior structures to the tibial cortex.
Main Methods:
- Analysis of 20 distal tibia MRI scans in coronal, sagittal, and axial planes.
- Two observers performed measurements on two separate occasions to assess inter- and intraobserver reliability.
- Measurements included distances of anterior structures and dimensional parameters of the distal tibia.
Main Results:
- The distal tibia at the plafond measured 39 mm (medial-lateral) and 36 mm (anteroposterior) on average.
- The anterior neurovascular bundle was an average of 3 mm from the anterior tibial cortex.
- Anterior tendinous structures were located less than 6 mm from the cortex, with excellent measurement reliability.
Conclusions:
- This study offers the first MRI-based anatomical description of the distal tibia.
- Crucial anterior anatomical structures are in close proximity to the distal tibia.
- Awareness of these close relationships is vital for safe internal fixation of distal tibia fractures.

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...
01:27Fractures: 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...

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
