Background:
Rotationplasty is one treatment option for femoral bone sarcomas in skeletally immature patients. This procedure can also be used to save failed limb salvage procedures such as infected prostheses and failed bone grafts in adults. Rotationplasty is only rarely indicated, and the surgical complications and risk factors for failure of the procedure that might influence the treatment or patient choices have not been well described.
Methods:
We retrospectively reviewed 19 patients who underwent rotationplasty focusing on surgical indications, surgical procedures such as the type of rotationplasty, and whether vessels were sacrificed and reconstructed with vascular anastomosis or preserved. Risk factors for failure of rotationplasty were categorized into either early or late postoperative complications.
Results:
Thirteen of 19 rotationplasties were done for patients diagnosed with primary sarcoma, 3 patients for unplanned excisions of sarcomas, and 3 patients for infection. Two of 19 patients did not have sufficient circulation resulting in amputation. Six of 19 patients underwent vascular anastomoses, and all of these anastomoses were successful. Three patients had multiple operations for infection before rotationplasty, and one patient's treatment failed so an amputation was required. As late complications, one patient had delayed bone union and one had postoperative infection that healed after removal of plate fixation. Two patients had malrotation of the tibia that resolved with revision surgery. One patient had a skin ulcer that healed with conservative treatment. One patient who had an unplanned excision had a hemipelvectomy for non-union 11 months after rotationplasty.
Conclusions:
Rotationplasty was successfully accomplished in 16 of the 19 patients (84 %) with sarcomas, unplanned excision of sarcomas or infection. Vascular anastomosis did not increase the risk of rotationplasty failure in our series. Patients appeared to have a higher risk of failure of rotationplasty after multiple operations, possibly because of inflammation around the vessels. The surgeon should be aware of the higher potential risk and consider vascular anastomosis for these patients.
