Shin Splints

Provided by www.time-to-run.com

Definition

Inflammation of the muscle attachments and interosseous membranes to the tibia (shin bone) on the inside of the front of the lower leg. Note: "shin splints" is a very widely used phrase and can refer to several lower leg injuries. The focus of this description is specifically on the inflammation described above.

Symptoms

Pain or tenderness along the inside of the shin, usually about halfway down the shin. Pain and tenderness may extend to the knee

Pain on palpation of the shin

Pain is most severe at the start of a run, but may disappear during a run, as the muscles loosen up. This is different to a stress fracture, where there is pain during weight bearing activities (walking, stair-climbing)

Causes:

Inflexible calf muscles and tight Achilles tendons - place more stress on to the muscle attachments

Overpronation (feet rotate too far inward on impact) excessive running on hard surfaces, such as concrete pavements

Incorrect or worn shoes

Overtraining, or a rapid increase in training load or intensity
Beginner runners are more susceptible to this problem for a variety of reasons, but most commonly due to the fact that the leg muscles have not been stressed in such a way before they started running.

Self-treatment:

Stop running, especially in the case of severe pain, if pain is mild, then reduce training load and intensity, and avoid downhill running and running on cambered surfaces

Take a course (5 - 7 days) of non-steroidal anti-inflammatory drugs

Apply ice to the shin area - for 10 minutes every 2 hours, in order to reduce the inflammation

Self-massage, using an anti-inflammatory gel, to the muscle only (along the inside of the shin).

Stretching of the gastrocnemius and soleus muscles. Hold for 30 secs. Relax slowly. Repeat to opposite side. Repeat stretch 2 - 3 times per day.

Remember to stretch well before running

Return to running gradually

Full recovery is usually between two to four weeks

Medical treatment:

Sports Medicine Doctor, if injury doesn't respond to self-treatment in 2 to 3 weeks

Orthotist or podiatrist for custom-made orthotics to control overpronation

Orthopaedic surgeon - if injury does not respond to treatment, a bone scan, diagnostic ultrasound or X-ray may be necessary to check for a stress fracture.

Alternative exercises

swimming, pool running, cycling (in low gear) "spinning"
avoid any weight-bearing exercises

Preventative measures

Stretching of the gastrocnemius and soleus muscles. Hold each stretch for 30 seconds, relax slowly.

Repeat stretches 2 - 3 times per day. Remember to stretch well before running.

Strengthening of foot and calf muscles.

1) Place a weight around the foot, and move your foot up and down from the ankle, with no movement in the rest of the leg. Or use a partner to grasp the foot and provide manual resistance.

2) Band exercises. Anchor one end of an exercise band (e.g; inner tubing of bicycle) to a heavy object, such as the leg of a couch. Loop the other end around the foot. Move the foot up, down, and from side to side against the band's resistance to exercise different muscle groups.

Correct shoes, specifically motion-control shoes and orthotics to correct overpronation

Always apply ice after running

Run on soft surfaces

Avoid overstriding, which places more stress onto the shins

Gradual progression of training program

Incorporate rest into training program
