Lower Leg Injury in High School Football Player Brooke Sallee, Andrew Noble, Danielle Doggett, Robert Confer, Edward Farrar, MD, Dale Blair, ATC Wenatchee High School Wenatchee,WA
History • This 16 y/o football player had previously fractured tibia and fibula while snowboarding on December 27, 1998 (at age 14).
Signs and Symptoms • He received a blow to the anteromedial aspect of distal lower leg while playing in a Friday night football game on September 22, 2000. • He was able to bear full weight, however was unable to run and perform functional activities.
History • The following Monday, 9/25, he was able to participate in low impact functional exercises. • He was virtually pain free and functional on Tuesday, 9/26 and was cleared for “go as can go” practice. • As he jogged to the practice field, he felt a snap in his lower leg.
Signs and Symptoms • Immediate disability and pain. • Significant deformity four inches proximal to medial malleolus. • Transported to emergency room with a vacuum splint
Differential Diagnosis • Osteogenic sarcoma
Diagnostic Imaging/lab tests • X-ray revealed an oblique fracture of the tibia approximately 2 inches distal to previous fracture site
Deviation from the Expected • Some radiolucency (sp) was noted on x-ray on the previous x-ray (3/99) 4 months post fx at what became the new fracture site
Discussion • Wolff’s law (weight encourages bone to heal) • Fibula was bearing more than share not allowing the tibia to take full weight.
Discussion • The oblique fx occurred due to a undectected stress fx (no pain in first month of season) • The lower leg “contusion” in the game on Friday night may have caused a slight cortical “irritation.”
Treatment • Open reduction, internal fixation with an intramedullary rod in the tibia • Fibular osteotomy (Wolff’s law)
Conclusions • Tibia stress fracture did not fully heal due to lack of stress on the bone. • Tibia also has a poor blood supply in the middle 1/3 of the bone • Implications: lack of weight bearing weakens bones (e.g. osteoporosis).
