Tibia Stress Fracture An anterior tibia stress fracture is considered a high risk stress fracture due to the combination of lack of adequate blood supply and high stress to the bone. Excessive or repetitive load on a bone can cause a mismatch between bone resorption and formation. The stress across bone will increase osteoclastic activity over osteoblastic bone formation.
This mismatch causes microfracture formation when the stress to bone continues and the osteoclastic activity remains dominate. Stress fractures of the tibia can occur at any location along the shaft, but are most commonly encountered at the posteromedial cortex. Less commonly seen are stress fracture of the anterior tibia shaft.
The incidence of tibial stress fractures in runners is 10-20%. Patients will typically begin to have slow onset of pain over a two to three week time frame. Pain typically worsens with activity.
Providers should inquire about a change in workout routine or a change in sneakers or orthotics. Patients should also be asked about menstrual irregularity. Https://www.youtube.com/watch?v=xYo4TK9W_Kk The hop test can be used to help identify a stress fracture.
(Note: useful for all lower extremity stress injuries, not specific to Tibia ) On physical exam, a tibia stress fracture will present with tenderness over the bone. There may also be soft tissue swelling and warmth. Special tests like a single leg hopping test and fulcrum test can be suggestive of a tibia stress fracture.
If you are experiencing symptoms that may be related to tibia stress fractures, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
