Purpose of the study: The purpose of this retrospective study was to evaluate the reliability of the sural flap with a distal pedicle for covering tissue loss of the posterior aspect of the heal and the malleolar region in diabetic patients.

Material and methods: We present a retrospective consecutive series with 28 month follow-up. Thirteen flaps in 13 patients (10 men, 3 women), mean age 64 years. A homolateral flap was used in all cases, covering on average 48 cm². Substance loss involved the hind foot in ten cases and the malleolar region in three. Three patients had recent bone trauma, four had chronic osteitis and six a pressure wound involving the heel. All patients had non-insulin dependent diabetes mellitus.

Results: The flap head in 24 days on average (range 18–45), the donor site in 15 days. Eleven patients were able to wear normal shoes. At last follow-up all patients were free of infectious recurrence. There was one flap necrosis, three necrotic borders (one skin graft), two cases of venous insufficiency, and ten cases of hypoesthesia of the lateral border of the foot.

Discussion: There have not been any reports in the literature of the neurocutaneous sural flap with a distal pedicle for diabetic patients. In our series, this flap was found to be a reproducible solution for covering substance loss of the heel and malleolar region in the diabetic.

Conclusion: This flap with a long pedicle does not require microvascular qualification. It is easy to perform, induces few functional sequelae. For diabetic patients, it is an alternative to amputation, without compromising future options since the vascular and muscle stock are preserved.

Purpose: Nonunion of the tibia is a therapeutic challenge requiring a good understanding of bone healing, bone substance loss and skin trophicity disorders. The fibula pro tibia Huntington procedure consists in transposing the homolateral fibula onto the injured tibia. This allows bridging the bone defect, realignement and stabilisation of the nonunion segment.

Material and methods: This retrospective series included eleven patients (ten men and one woman), mean age 32 years (16–62). The cause of the injury was a traffic accident in six cases, defenestration in one, adamatinoma in one and osteomyelitis in one. The skin was broken in nine patients with septic nonunion in seven. Mean follow-up was 13 years (1–21).

Results: Mean delay to healing was 10.5 months (8.5 for post-traumatic nonunions) and was achieved in eight cases. A higher tibial nonunion persisted after resection of an adamantinoma measuring 22 cm and two patients had to be amputated in a context of acute suppuration. Walking without crutches was possible for eight patients whose tibia had healed and the mean pain score was 2 / 10.

Discussion: Several solutions can be proposed for patients with a tibial nonunion. The inter-tibiofibular graft requires a large bone graft in patients who have already had several operations. Th Papineau method only provides cancellous bone which is mechanically weak. The Ilizarov method can allow bone transfer and dynamisation of the nonunion with compression distraction. Microanastomosis transfers using a free fibula require a trained team with the risk of potential infection of the anastomoses in these infected patients. The Huntington method has the advantage of providing osteosynthesis without the inconvenients of inert material. The fibular acts like a biological plate with good vascularisation and stability to realign and lengthen the tibial segment.

Conclusion: This surgical technique is a supplementary therapeutic means for treating (septic) nonunion of the tibia. It is easy to perform and may be the last salvage method. The advantages are: a solid compact graft fixed in the mechanical axis of the tibia, possibility of bridging bone loss of more than 28 cm, short operative time without risk of complications related to graft harvesting, shorter hospital stay.

There is ambiguity concerning the nomenclature and classification of fractures of the ring of the second cervical vertebra (C2). Disruption of the pars interarticularis which defines true traumatic spondylolisthesis of C2, is often wrongly called a pedicle fracture. Our aim in this study was to assess the influence of asymmetry on the anatomical and functional outcome and to evaluate the criteria of instability established by Roy-Camille et al. We studied the plain radiographs and CT scans of 24 patients: 13 were judged to be asymmetrical, ten were considered unstable and 14 stable.

Treatment was with a Minerva jacket in 15 fractures and by operation in nine. Surgery was undertaken in patients with severe C2 to C3 sprains. One patient with an unstable lesion refused operation and was treated conservatively with a poor radiological result.

Our study showed that asymmetry of the fracture did not affect the outcomes of treatment and should not therefore influence decisions in treatment. The criteria of Roy-Camille seem to be reliable and useful. We prefer the posterior approach to the cervical spine, which allows both stabilisation of the fracture and correction of a local kyphosis.
