![]() ![]() More focal tenderness, the presence of anterior tibial tenderness, or any significant swelling suggests stress fracture. Tenderness from MTSS should involve at least 5 cm of the tibial border. Prolonged stress may generate a periosteal reaction detectable as a “rough” or “bumpy” feel upon palpation. Pain that persists more than five minutes post-activity carries a higher suspicion of stress fracture.Ĭlinical evaluation demonstrates diffuse tenderness over the posteromedial tibial border. Initially, symptoms may subside during training, but as the condition progresses (toward stress fracture), symptoms may linger throughout activity or even at rest. Symptoms are often worse with exertion – particularly at the beginning of a workout. The clinical presentation of MTSS includes vague, diffuse pain over the middle to distal posteromedial tibia. Prolonged insult may lead to a tibial stress fracture, and many authors now believe that MTSS and stress fracture represent two different points along a continuum of bony stress reaction. Stress reactions occur when the normal adaptive remodeling response cannot keep pace with excessive training loads, i.e., high demands with inadequate recovery times. Healthy bone responds to this stress by remodeling itself more densely. The stress of exercise can temporarily weaken bone. Research suggests that traction periostitis may be an inflammatory precursor to a tibial stress fracture. The importance of increasing awareness amongst radiologists.Įuropean Journal of Radiology 62 (2007), 16-26.Early etiological theories focused on myofascial strain, but current evidence shows that a bony stress reaction is the most likely cause of MTSS.

Correlation of clinical symptoms and scintigraphy with a new magnetic resonance imaging grading system. Stress fractures can be divided into high and low risk stress fractures according to their likelihood of uncomplicated healing with conservative therapy.įracture of the posteromedial aspect of the tibiaįredericson M, Bergman AG, Hoffman KL, Dillingham MS. Stress fractures are most common in the weight-bearing bones of the lower extremity, especially the lower leg and the foot (Figure). With ongoing exposure, pain will last after the training, eventually causing the athlete to stop exercising. Insidious onset of pain and swelling over the affected region is the most important complaint, initially during the activity. Sedentary people may also develop stress fractures if suddenly an active Training or training circumstances (new shoes, other training surface etc.)Īnd thus at increased risk of developing a stress fracture. Recruits are subject to change in training intensity (increased), type of Stress fractures usually occur after a recent change in training regimen hasĮspecially professional or recreational athletes and militairy Muscle fatigue can also play a role in the occurrence of stress fractures.įor every mile a runner runs, more than 110 tons of force must be absorbed by the legs.īones are not made to withstand so much energy on their own and the muscles act as shock absorbers.Īs muscles become tired and stop absorbing, all forces are transferred to the bones. When enough stress is placed on the bone, it causes an imbalance between osteoclastic and osteblastic activity and a stress fracture may appear.
