THP is generally performed as a lifesaving protocol to return the patient to an active life. Case report: A 12‑year male patient exposed to major pelvic trauma with bilateral THP survived the trauma and mul‑ tiple lifesaving operations. The anterolateral thigh fap is the method used for wound reconstruction. The follow‑up was ended with colostomy and cystostomy with wheelchair mobilization. To the best of our knowledge, there have been a few bilateral THP reports, and our case is the second one to be successfully treated with an anterolateral thigh fap. Conclusion: MPT with THP is the primary cause of death among trauma patients. Life‑threatening hemorrhage is the usual cause of death, which is a strong indication for THP to save life.
