In this randomised controlled trial, we evaluated
the role of elastic compression using ankle injury stockings (AIS)
in the management of fractures of the ankle. A total of 90 patients
with a mean age of 47 years (16 to 79) were treated within 72 hours
of presentation with a fracture of the ankle, 31 of whom were treated
operatively and 59 conservatively, were randomised to be treated
either with compression by AIS plus an Aircast boot or Tubigrip
plus an Aircast boot. Male to female ratio was 36:54. The primary
outcome measure was the functional Olerud–Molander ankle score (OMAS).
The secondary outcome measures were; the American Orthopaedic Foot
and Ankle Society score (AOFAS); the Short Form (SF)-12v2 Quality
of Life score; and the frequency of deep vein thrombosis (DVT). Compression using AIS reduced swelling of the ankle at all time
points and improved the mean OMAS score at six months to 98 (95%
confidence interval (CI) 96 to 99) compared with a mean of 67 (95%
CI 62 to 73) for the Tubigrip group (p <
0.001). The mean AOFAS
and SF-12v2 scores at six months were also significantly improved
by compression. Of 86 patients with duplex imaging at four weeks,
five (12%) of 43 in the AIS group and ten (23%) of 43 in the Tubigrip
group developed a DVT (p = 0.26). Compression improved functional outcome and quality of life following
fracture of the ankle. DVTs were frequent, but a larger study would
be needed to confirm that compression with AISs reduces the incidence
of DVT. Cite this article:
We have reviewed a series of 56 consecutive patients treated by the Ilizarov circular fixator for various combinations of nonunion, malunion and infection of fractures. We used segmental excision, distraction osteogenesis and gradual correction of the deformity as appropriate. Treatment was effective in eliminating 40 out of 46 nonunions and all 22 infections. There were two cases of refracture some months after removal of the frame, both of which healed securely in a second frame. Correction of malunion was good in the coronal plane but there was a tendency to anterior angulation, often occurring in the regenerate bone rather than at the original fracture site, after removal of the frame. This was associated with very slow maturation of regenerate bone in some patients, occurring largely, but not exclusively, in those who smoked heavily. Patients expressed high levels of satisfaction with the outcome, despite relatively modest improvements in pain and function, presumably because their longstanding and intractable nonunion had been treated. None the less, the degree of satisfaction correlated strongly with the degree of improvement in pain and function. We emphasise the importance of a multidisciplinary team in the assessment and support of patients undergoing long and demanding treatment. The Ilizarov method is valuable, but research is needed to overcome the problems of delayed maturation of the regenerate and slow or insecure healing of the docking site.
