It continues between the peroneus longus muscle and the fibula. Just distal to the head of the fibula, the nerve becomes subcutaneous. This nerve provides cutaneous innervation to the lateral aspect of the leg below the knee via the lateral cutaneous nerve of the calf. The common peroneal nerve then travels across the lateral head of the gastrocnemius muscle. Figure 1 demonstrates the course of the common peroneal nerve, which is also referred to as the common fibular nerve.ĭistribution of the peroneal nerve. Of note, the same fibers that run laterally in the sciatic nerve to innervate the short head of the biceps femoris are the fibers that will form the common peroneal nerve at the knee. The sciatic nerve divides into the common peroneal (fibular) and tibial nerves proximal to the popliteal fossa. The anterior divisions of the ventral rami innervate the other three hamstring muscles and ultimately form the tibial nerve. The posterior divisions of the ventral rami ultimately form the common peroneal nerve and innervate the short head of the biceps femoris muscle. It receives contributions from the L4–S3 ventral rami and exits the sacral plexus by passing through the greater sciatic foramen and traveling inferior to the piriformis muscle. The largest nerve in the sacral plexus and in the human body is the sciatic nerve.

Along with casting serial manipulation can also be done. Casting is also done to make it stable on its position. It includes the stretching exercises for the fore foot and hind foot. But some of the cases can be treated with non-surgical treatment. Most of the cases of rocker bottom feet disease require surgical treatment. The rocker bottom feet can be treated in two ways i.e. As in trisomy, the chromosome numbers are less with respect to the original number of chromosomes i.e. The most reported cause behind rocker bottom feet is the congenital abnormality in genes and chromosome number. Some of them are spina bifida, trisomy 13, 14, 15 or 18 and arthrogryposis multiplex congenita. Other than congenital issue, it can also occur secondary to the other musculoskeletal and neurological conditions. Rocker bottom feet is a congenital disease so it occurs due the defect in chromosomes number. The child when walk, he walk moving inside of the foot position due to abnormal positioning of talus bone. The foot appear as a winged structure instead of an aligned position with respect to the hind foot. The back side of foot is elevated upward due to the flex in the foot ankle. The front side of foot is pointed upward along with the mid area of foot straighten vertically.
The disease is judged when the baby start walking.
The associated symptoms of rocker bottom feet are as follows: If the birth defect is in the foot regarding talus bone then the condition is known as rocker bottom feet syndrome. It is a genetic disorder with combination of birth defects. Trisomy 18 is also known as Edward’s syndrome and trisomy 13 is known as patau syndrome. Like that there are two other types of trisomy i.e. Trisomy is a condition in which the fetus contain less number of chromosomes than usual i.e. In this disease, the front end of foot is pointed upward and there is no arch present in the foot. Rocker bottom feet is also known as congenital vertical talus because the talus bone of foot arrange itself vertically leading to the miss arrangement of other foot bones.
In this disease, the bones of the foot of baby are shifted on the top side due to the wrong positioning of talus bone of foot during development of fetus. Rocker bottom feet is a congenital disease.
