Background. Subtalar nonunion has a detrimental effect on patients' function, and pose a significant challenge for surgeons particularly in the setting of higher risk factors. Methods. We retrospectively analyzed a consecutive series of 49 subtalar nonunions between October 2001 and July 2013. Patient records and radiographs were reviewed for specific patient demographics and comorbidities, subsequent treatments, revision fusion rate, use of bone graft, complications, and clinical outcome. Results. Forty-nine patients with a mean age of 49 years (range 23–80) were included. Sixteen (32%) were heavy smokers (>1 pack per day) and five (10%) had diabetes. Forty one (84%) of the nonunions were symptomatic and underwent a revision procedure at a mean of 16 months (range 2.8 to 57) from the time of the primary arthrodesis. Four of these patients required a triple arthrodesis at the time of revision. Bone graft was used in all cases, and in 25 cases (61%) additional adjuvant orthobiologics. Thirty-two (78%) of the patients achieved a solid arthrodesis at a mean of 3.4 months (range 1.4 to 7.6). Patients who were diabetic and smokers as a group had a 68% rate of union. Of the nine nonunions following a revision arthrodesis, five were in the setting of a prior ankle arthrodesis, three were complicated by a deep infection, and one had no obvious risk factors. Four of the repeat nonunions elected to not undergo an additional procedure, two had a successful third attempt at arthrodesis, one had an additional nonunion followed by a successful fourth attempt at arthrodesis, one had a successful tibiotalocalcaneal arthrodesis, and one ultimately required a below-knee amputation. Discussion. Management of subtalar nonunions pose a significant challenge with a low rate of arthrodesis at 78% fusion rate, but which can be achieved with rigid fixation and utilization of bone graft and orthobiologics

Aims

The aim of this retrospective study was to compare the functional and radiological outcomes of bridge plating, screw fixation, and a combination of both methods for the treatment of Lisfranc fracture dislocations.

Open reduction and internal fixation of high-energy pilon fractures are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. A total of 17 consecutive patients with pilon fractures of AO/OTA type 43-B3 (n = 1), type C2 (n = 12) and type C3 (n = 4) were treated by indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov fixator. The calcaneal ring was removed at a mean of 3.7 weeks (3 to 6). A total of 16 patients were available for follow-up at a mean of 29 months (23 to 43). The mean time to healing was 15.8 weeks (13 to 23). Nine patients had pin-track infections but none had deep infection or osteomyelitis. Four patients (25%) had malunion. Fair, good or excellent ankle scores were found in 14 patients. External fixation with a ring fixator achieves stable reduction of the fractured fragments without additional trauma to soft tissues.

With minimum complications and good healing results, the Ilizarov apparatus is particularly useful for high-energy pilon fractures.
