A Novel Method to Prevent Terminal Appositional Overgrowth Following Pediatric Below Knee Amputations: A Case Series and Review of the Literature

摘要

The terminal overgrowth of the tibia following pediatric transtibial amputation is a common problem leading to pain, disability, and repeat surgical procedures. We present three patients who underwent transtibial amputation due to sarcoma of the lower extremity followed by compress osseo-integration prosthesis fixation. The minimum follow-up was 1 year. The average age of patients was 10.8 years. There were no complications that required surgical revision. To date, there has been no evidence of terminal appositional overgrowth in this series. The application of an end-cap implant utilizing compressive osseointegration fixation can prevent terminal bone overgrowth in pediatric transtibial amputations.
