Aims
Patients with diabetes are at increased risk of wound complications after open reduction
and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions
and allows anatomical reduction of the mortise.
Patients and Methods
We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous
fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1
or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as
amputation, mortality and functional outcomes was determined.
Results
Two patients developed lateral side wound infection, one of whom underwent wound
debridement. Three other patients required re-operation for removal of symptomatic
hardware. No patient required a below-knee amputation. Six patients died during the study
period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short
Form-36 Mental Component Score and Physical Component Score were 53.2 (95%
confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean
Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale
total score was 32.9 (95% CI 16.0 to 49.7).
Conclusion
Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients
with diabetes was associated with a low incidence of wound and overall complications,
while providing effective surgical fixation.

Ankle fractures are common
1
and are usually
treated by open reduction and internal fixation
(ORIF).
2,3
The fibular plate is inserted through
a lateral incision over a bony prominence
which can result in wound complications in at-
risk individuals, potentially leading to
amputation. Diabetes mellitus can result in a
poor wound healing environment through
hyperglycemia-induced irreversible protein
glycosylation and tissue hypoxia via macro-
and micro-vessel arteriosclerotic disease.
4
Consequently, patients with diabetes are at
higher risk of wound breakdown or loss of
fracture fixation following standard ORIF of
displaced ankle fractures.
2,5,6
Where possible
non-operative treatment with prolonged cast
immobilisation for ankle fractures in these
patients may be recommended to avoid wound
complications.
5
This treatment however delays
the recovery time and increases the potential
for subsequent ankle deformity.
2,5
There is no
consensus on the optimal management of
ankle fractures in patients with diabetes.
2,7
A
technique to obtain fracture reduction and
maintain fixation with reduced wound risks
would therefore be beneficial.
A fibular nail, inserted percutaneously
through the tip of the fibula, avoids the long
lateral incision and dissection required for
plate fixation.
8,9
As an intramedullary device,
it does not disrupt the periosteal blood supply,
resulting in better local bone blood flow and
cellularity at the fracture site
10
therefore
optimising the local environment for
secondary bone healing.
We have previously reported our technique
of fibular nailing and its successful application
in a cohort of 105 patients.

The current
retrospective case series reviewed patients at
two centres to assess the safety and
effectiveness of fluoroscopic reduction and
fibular nail fixation in diabetic patients. We
