Overgrowth After Pediatric Tibial Spine Repair with Symptomatic Leg Length Discrepancy: A Case Report.

CASE: A 12-year-old girl sustained a right-sided tibial spine fracture while jumping on a trampoline. Postoperative course was complicated initially by arthrofibrosis requiring manipulation under anesthesia and subsequent leg length discrepancy attributed to posttraumatic overgrowth necessitating femoral epiphysiodesis. Ten years after initial injury, she reported her knee to be 63% of normal and an International Knee Documentation Committee score of 63.2. Symptomatic overgrowth requiring epiphysiodesis after tibial spine repair has not been previously reported to our knowledge.

CONCLUSION

Tibial spine fixation, although previously associated with growth arrest because of physeal damage, may also result in symptomatic limb overgrowth.
