Inflammation of the inner shin bone

Diagnosis: INFLAMMATION OF THE INNER SHIN BONE
(MEDIAL TIBIAL PERIOSTITIS, “SHIN SPLINT”)


Anatomy:
The calf muscles are divided in three muscle groups (compartments) by powerful muscle membranes (fascies). A forward, an exterior and a rear muscle group (which is divided into a superficial and a deep part). The large rear muscle groups’ muscle membrane is fastened on the inner edge of the shin bone (tibia), while the forward muscle group is fastened on the external edge of the shin bone (photo).

Cause: In cases of repeated uniform loads, a stress related inflammation, can occur where the muscle membrane fastens on the edge of the shin bone. The condition is most often seen in athletes with a tendency to rotate the foot outwards (hyperpronation) or with a high foot arch. Frequent change of running surface or shoes increases the risk.

Symptoms: Pain on the inner edge of the shin bone, aggravated upon applying pressure, load (running) and stretching in the foot joint against resistance (flexion). The pain is often localized to the lower part of the shin bone. Sometimes an irregular bone edge can be felt on the shin bone.

Acute treatment:

Examination: In light cases medical examination is not necessarily required. In cases with more pronounced pain or lack of progress despite relief, medical examination is recommended to ensure the diagnosis and rule out amongst other things a stress fracture. A medical examination is usually sufficient in order to make the diagnosis. In some cases it may be necessary to supplement with X-rays, scintigraphy or ultrasound scanning.

Treatment: The treatment comprises relief, stretching and slow rehabilitation. It is imperative that there are good shock absorbing soles in the shoes.

Rehabilitation of children and adolescents: INSTRUCTION

Complications: If the course does not progress smoothly, you should be medically re-examined to ensure that the diagnosis is correct, and that complication have not arisen in the form of stress fracture.

Special: Shock absorbing shoes or inlays will reduce the load.
