Purpose of the study: The difficulty of achieving successful reconstruction after tissue loss involving the lower third of the leg, particularly the malleolar region in septic cases, is well known. We report our experience with sequential surgery to treat open fractures of the lower leg and examine the contribution of the distally-based neurocutaneous sural flap.

Material and methods: The following protocol was used for the treatment of tissue defects involving the lower third of the leg and the ankle in 16 patients: repeated wound debridement, change in fixation system for 13 cases, rapid cover of the posterior segment of the leg with an island-dissected distally based neurocutaneous sural flap. Ten nonunions were treated later with a bone graft. Mean age in this series of 14 men and 2 women was 34 years (range 21–70 years). Thirteen patients were secondary hospitalization patients. The Gustilo classification after debridement was class IIIb. Time to cover ranged from one to eight months.

Results: Healing was achieved in three weeks. For three cases, revision was necessary due to re-activation of an infectious focus. All fractures healed (with tibiotalar fusion in two cases).

Discussion: The distally-based pediculated neurocutaneous sural flap is an interesting alternative to microanastomosis flaps for reconstruction of tissue defects of the lower third of the leg. Harvested from the posterior aspect of the calf which is generally spared, this flap must be carefully planned since there is no potential for augmenting the covering capacity. Great care must be taken to protect the pedicle; in our experience tunnelisation must be avoided. This flap also allows cover of a sterile osteosynthesis plate and resists local infection well. It can be raised easily if a bone graft is later necessary. In trauma victims, the esthetic and sensorial prejudice can be considered minor.

Conclusion: The distally-based neurocutaneous sural flap greatly contributes to our strategy for the management of tissue defects involving the lower third of the leg. Its main limitation is its size which can rarely exceed 80 cm2 in our experience.

Purpose: Prognosis of open leg fractures is better when cover flaps are used early to cover tissue loss. Beyond eight days after high-energy trauma (Byrd stage III and IV), the therapeutic strategy requires discussion. The purpose of this study was to analyse the influence of flap covers on these complex fractures.

Material and methods: We conducted a retrospective analysis of 26 patients operated on from 1996 to 201. The therapeutic sequence was debridement, external fixation, and flap cover. High-energy trauma predominated (n=21). We used homolateral leg flaps (n=24, ten muscle flaps and 14 fasciocutaneous flaps) and free latissimus dorsi flaps (n=2). Flap cover was performed on day 8 (n=13), between day 8 and day 45 (n=11), or after day 45 (n=2).

Results: Cover flaps failed in eight cases requiring revision surgery. Time to cover or type of flap was not statistically related with initial severity of the injury. Time to cover influenced the type of flap chosen by the surgeons: 8/13 muscle flaps performed before day 8 versus 10/13 fasciocutaneous flaps after day 8 (p< 0.05). Complementary bone grafts were used for 18 patients before the third month leading to bone healing before ten months. Serious infection occurred in 16.6% of patients in the group treated before day 8 and in 36.66% of patients in the group treated after day 8. The severity of the initial injury and time to cover were not predictive of functional outcome.

Discussion: Proper management of high-energy leg fractures (Byrd stage III and IV) remains controversial. Most authors prefer external fixation to achieve skeletal stability. The growing interest for plastic surgery techniques for the leg segment has led to using locoregional homolateral leg flaps even after day 8. At this phase, we prefer muscle flaps. This attitude has demonstrated its usefulness in terms of healing time and its limitations due to the high risk of infection. Complementary bone grafting is performed before three months if signs of correct bone healing are absent on the control x-rays.

Purpose: Inverted pediculated fasciocutaneous flap is an alternative to microanastomosed free flap for cover of tissue loss of the lower third of the leg in trauma victims. We report our experience in fourteen patients.

Material and methods: Fifteen fasciocutaneous inverted pediculated island flaps were performed in fourteen trauma victims with major tissue loss of the lower limbs. Mean age was 42 year (range 24 – 70). There were thirteen men and one woman. The fracture was located on the lower third of the leg and involved the diaphysome-taphyseal junction in thirteen patients (associated with loss of heal tissue on one), the fibular malleolus in one and the tibial column in one. The Gustilo classification was two grade 0, three grade I, eight grade IIIB, and one grade IIIC. Four patients were given first-intention treatment. For the referral patients treated secondarily, three had a dehiscent wound with an exposed fixation plate.

A supramalleolar lateral flap was used in six patients (40%), a sural neurocutaneous flap with a distal pedicle in seven (47%), and a sural neurocutaneous flap with a distal pedicle in two (13%). Seven patients (50%) had a bone graft.

Results: Wound healing was achieved in thirteen patients, with three infectious complications. The one failure involved a sural neurocutaneous flap (grade IIIC fracture). The fixation plate was preserved under the flap in one patient who developed secondary nonunion. Fracture healing was achieved in all cases.

Discussion: Use of island fasciocutaneous flaps with a distal pedicle for the treatment of tissue loss of the lower third of the leg has grown steadily since the introduction of the concept. The principal advantage, beyond the simplicity of the flap procedure, is to spare locoregional vessel and muscle stock. Our series confirmed that this method can give good results if the flaps are carefully planned. This method should not be recommended as an emergency procedure. Combining two fasciocutaneous flaps could be a salvage solution in certain cases where the trauma context implies less concentration in the aesthetic and sensorial result.

Conclusion: Use of fasciocutaneous flaps with a distal pedicle is a first choice solution for covering tissue loss of the lower third of the leg and foot. This method should not be proposed as an emergency procedure.

Purpose: Scaphotrapezotrapezoidal (STT) pain is common but often asymptomatic. Medical treatment may be proposed if symptoms become bothersome. In case of failure, several surgical solutions may be proposed. The purpose of this work was to assess outcome in a series of eleven STT arthrodeses performed for isolated STT osteoarthritis.

Material and methods: Ten patients, three men and seven women (11 hands), mean age 63 years, developed STT osteoarthritis which was treated by arthrodesis. All patients experienced pain for daily life activities and had diminished wrist movement. According to the Crosby radiographic classification, three were one grade I, four grade II, and five grade II with carpal misalignmen t. One patient had chondrocalcinosis and six had tendinitis of the flexor carpi radialis. The anterior approach was used for three patients and the lateral approach for seven. Nine patients had an iliac graft to fill bony defects resulting from anterior wear. Pin fixation was used in six cases and staple fixation in five. An antebrachiopalmar cast was maintained for at least six weeks after surgery.

Results: At mean follow-up of 62 months, the pain score improved in all patients (p=0.05). There was no significant difference in motion, excepting decreased wrist extension (12°, p=0.03). Grasp and pinch force were not modified by STT arthrodesis. All patients were able to resume their former recreational and occupational activities. There was no worsening of the five cases with intracarpial deaxation. Four patients developed non-union (three pin fixations, one staple fixation), which was symptomatic in only two. These patients underwent successful revision using the same fixation technique. There were no complications.

Discussion: Like other series reported in the literature, our series of STT arthrodeses demonstrated effective pain relief. However, unlike former work, we were unable to obtain a significant reduction in the radial inclination force, or radio-carpal conflict. The other therapeutic option is resection of the distal pole of the scaphoid which provides more rapid clinical results but which leads to inevitable misalignment of the carpus.

Conclusion: We have decided to retain STT arthrodesis with iliac graft for patients with STT osteoarthritis, especially for young patients.
