Bones of the Lower Limb: Femur and Patella

Bones 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...

Area of Science:

Orthopedic Surgery
Pediatric Orthopedics
Traumatology

Background:

Patellar dislocations are uncommon, with irreducible and vertical axis dislocations being particularly rare.
Neglected patellar dislocations, especially in pediatric cases, are exceedingly rare in medical literature.

Purpose of the Study:

To describe the clinical presentation and management of a unique case of neglected vertical patellar dislocation in a pediatric patient.
To highlight the diagnostic challenges and surgical approach for irreducible patellar dislocations.

Main Methods:

Case report of a 6-year-old boy with a neglected vertical patellar dislocation.
Initial missed diagnosis followed by open reduction after two months.
Analysis of the biomechanical factors contributing to the irreducible dislocation.

Main Results:

The patient presented with a neglected vertical patellar dislocation following an external rotational knee strain.
Open reduction was performed two months after the initial injury.
The lateral extensor retinaculum's rotational tension was identified as the locking mechanism.

Conclusions:

Neglected vertical patellar dislocations are rare but require prompt diagnosis and surgical intervention.
Understanding the specific locking mechanisms is vital for successful open reduction in such cases.
This case underscores the importance of thorough evaluation in pediatric knee injuries to avoid diagnostic delays.
