Ankle fusion

Ankle fusion, or ankle arthrodesis, is surgery of the ankle to fuse the bones to treat arthritis and for other purposes.[1] There are different types of ankle fusion surgery. The surgery involves the use of screws, plates, medical nails, and other hardware to achieve bone union.[1] Ankle fusion is considered to be the gold standard for treatment of end-stage ankle arthritis.[1] It trades joint mobility for relief from pain. Complications may include infection, non-union, and, rarely, amputation.[1]

Tibiotalocalcaneal arthrodesis

Tibiotalocalcaneal (TTC) arthrodesis is a special type of ankle fusion.[2][3][4][5] It is used in select situations, for instance as a salvage therapy in severe complicated cases or in other situations.[2] One major approach to TTC arthrodesis uses an intramedullary (IM) medical nail.[2][6][7][3][4] A 2011 systematic review reported the rate of bone union to be 87%, with a range of 74 to 93% in different studies.[6] The average time to union was 4.5 months.[6] Only 26% of cases of non-union required revision fusion, with the remaining cases being asymptomatic or not being severe enough to require revision.[6] It was concluded that the nail can oftentimes provide structural support and relief from pain even without union.[6] The complication rate was 56%, with hardware-related problems comprising a majority of complications.[6] The rate of reoperation was 22%, with screw removal done in 11.4%, nail removal done in 4.2%, revision fusion done in 3.4%, and amputation in 1.5%.[6] The review concluded that there is a good fusion rate with TTC arthrodesis using an IM nail but that the surgery has a high rate of complications.[6] On the other hand, a 2016 review concluded that there was a low rate of complications.[7]
