Some patients suffer from internal bow legs, a condition in which the knees appear close together while the feet are far apart, which increases the pressure on the knee joint and changes the normal way of movement.

 

Causes of Internal Bowlegs 

The patient usually suffers from Internal Bowlegs due to the following reasons:

 

     Blount’s disease, which is a disorder in the growth of the shin, and its symptoms often appear in adulthood.

     Neglecting treatment for osteomalacia in early childhood as a result of vitamin D deficiency.

     A fracture of the growth center at a young age leads to deformities during growth.

     Failure to heal an old fracture properly, leading to bone bending.

     Dwarfism, which is a disease that affects an individual as a result of a defect related to the child’s growth process.

     Severe joint osteoarthritis.

     Obesity.

     Osteoporosis.

     Kidney or liver disease, as it affects the concentration of both calcium and vitamin D in the body.

     Growth of bone tumors near the knee.

 

Complications of Internal Bowlegs 

Internal bow legs have many complications, including:

 

     Osteoarthritis of the knee joint occurs at an early age, which leads to uneven loads on the surface of the knee joint.

     Obvious limbing while walking.

     Recurring joint infections.

 

Treatment of Internal Bowlegs 

Surgical intervention is the appropriate treatment for cases of Internal Bowlegs, especially if the curvature is noticeable. Surgical treatment aims to restore the straightness of the leg, and the process of Internal Bowlegs is performed in two ways:

     Correction of bowed legs using plate and screws

 

During this operation, the surgeon makes a simple, osteotomy to distal femur of proximal tibia, then fixes the bone cut with plates and screws in the correct position.

 

     Correction of bowed legs using an external fixator

 

During the operation, the surgeon makes a bony incision in osteotomy to distal femur of proximal tibia, then fixes the tibia in the arched position using an external fixator. After ten days, the surgeon begins the process of gradually correcting the arch, where the doctor twists the nuts of the device several times a day over the course of a few weeks until the leg straightens.
