TIBIAL STRESS FRACTURE
The patient is usually an active individual who has shin pain that came on slowly. Overuse from running or prolonged activity on hard surfaces may be evident in the history.
If a repetitive stress is applied to bone such as with running, the ability to remodel may be overwhelmed because of inadequate healing time. There is still debate as to whether stress to bone is due to weak muscles or fatigue that causes increased bone loading or more to the forceful repetitive contraction ofmuscles and the imposed stress at their origins onto bone. Biomechanical risk factors includede high arch , leg-length inequality, and forefoot varus. Tibial stress fractures account for half of all stress fractures occurring in athletes.
