Optimal treatment of articular fractures is open anatomic reduction and rigid internal fixation. In pilon fractures, this has been associated with unacceptable complication rates.

The cutaneous blood supply of the anterior aspect of the distal tibia is from short direct radial vessels which themselves arise from arteries closely adherent to the deep fascia. On the anteromedial aspect of the leg the deep fascia is fused with the periosteum. We hypothesise that shearing associated with displaced fractures divide these short radial vessels, rendering the skin critically ischaemic. Standard extensile approaches lead to further devitalisation and wound breakdown. It follows that a direct approach onto the fracture line should do minimal extra damage to the blood supply.

Of 97 pilon fractures, 53 have required an open reduction. Median age 43, 39 male. Mechanism of Injury: fall-41, RTA-10, other-two. 19% open (60% IIIB). Time to surgery nine days.

A longitudinal incision with full thickness flaps is based directly over the fracture, not necessarily following internervous planes.

Anatomic reduction was achieved in all cases. There was only one complication of wound breakdown (2%).

This technique affords a safe and reliable approach to the fractured articular surface. Lack of wound breakdown may rely on the use of fine-wire circular frame external fixators for stabilisation of the proximal fracture. Whether this approach will allow plate fixation, remains to be seen.

Os calcis fracture patterns in ten children (mean age 12. 8) with eleven fractures were classified using plain films and CT scans and found to be similar to those in adults.

All except two of the fractures (which were not significantly displaced) were treated with open reduction and internal fixation. In all cases it was possible to achieve anatomic reduction and rigid internal fixation. Eight patients had ‘excellent’ long-term clinical results.

One patient with a court case pending scored ‘good’, and one patient with an ipsilateral talar neck fracture scored ‘fair’. This patient had mildly limited ankle movement; all others had full ankle movement. Six had full subtalar movement, in 2 it was mildly limited and in three it was moderately limited (50–80%). There was no evidence of abnormality of the physes on follow up x-rays. We conclude that operative treatment of these fractures yields optimal results.

Background: Fracture non-union remains a severe clinical problem. The methods of Ilizarov allow a new approach using a tensioned fine wire circular frame to construct cylinders around limb segments that are then manipulated with respect to each other with deformity correction using hinges. Ilizarov introduced the concept of bone formation in distraction. The use of fine wires and non-invasive techniques minimise bone and soft tissue damage.

Method: Two hundred consecutive non-unions treated by the use of an Ilizarov frame were studied prospectively. The first 100 cases to have finished treatment were analysed. The mean time from fracture was 22.8 months (range: six months to 37 years) and the mean number of surgical procedures was four (range: one to 122). Eighty-eight percent affected the tibia. Unifocal compression was also used where bone loss was not a problem.

Results: Ninety-three fractures united. There were two amputations for overwhelming infection, four refractures and one defaulter. Infection, present in 56 cases at presentation was eradicated in all successful cases. Time in the frame for unifocal distraction (n=6) was 6.0 months (2.5-13), for unifocal compression (n=36) was 8.4 months (2.8-20), for bifocal compression distraction (n=33) 10 months (2.9–17.4) and for bifocal excision distraction (n=24) 19 months (6.5–41). Comparing times in frame for tibial bifocal cases, compression/distraction was 9.1 months (2.9–17.4), excision with shortening and relengthening was 15.7 months (6.5–23.6) and excision/transport was 23.5 (12.6–41.5), indicating increasing time required for more radical treatments.

Conclusion: The Ilizarov method provided an excellent technique for the treatment of non-unions. The technique was initially difficult for the surgeon and the patient but, with increasing experience, treatment times were reduced and the frames became progressively more manageable and less painful. In our hands, the Ilizarov frame has become the treatment of choice for all but the simplest non-unions.
