We present in this work our experience with the sural fasciocutaneous flap to treat coverage defects following a lower limb posttraumatic lesion. This work is a review of the fasciocutaneous sural flaps carried out in different centres between 2000 and 2005. The series consist of 14 patients, 12 men and 2 women with an average age of 38 years (23–54) and with a medium follow-up time of 2 years (12–48 months). In all of the cases, aetiology was a lower limb injury being the most frequent the distal tibial fracture (eight patients), followed by sequelae from Achilles tendon reconstruction (two patients), fracture of the calcaneus (two patients) and osteomyelitis of the distal tibia (two patients) secondary to an open fracture. Associated risk factors in the patients for performing a fasciocutaneous flap were diabetes (1 case) and cigarette smoking (4 cases).

The technique is based on the use of a reverse-flow island sural flap with the superficial sural artery dependent on perforators of the peroneal arterial system. The anatomical structures which constitute the pedicle are the superficial and deep fascia, the sural nerve, external saphenous vein, superficial sural artery together with an islet of subcutaneous cellular tissue and skin.

The flap was viable in 13 of 14 patients. Only in one case, a diabetic patient, the graft failed. No patient showed signs of infection. Slight venous congestion of the flap occurred in two cases. No further surgical intervention of the donor site was required because of morbidity. In two cases partial necrosis of the skin edges occurred which resolved satisfactorily with conservative treatment.

The sural fasciocutaneous flap is useful for the treatment of complex injuries of the lower limbs. Its technical advantages are: easy dissection with preservation of more important vascular structures in the limb, complete coverage of the soft tissue defect in just one operation without the need of microsurgical anastomosis. All of that results in a well vascularised cutaneous islet and thus a reliable flap

Aims: The purpose of this study is to review the results of our experience in the treatment of all of the cases of traumatic knee dislocations (TKD) from 1988 to 1998 by means of a retrospective study. Methods: 26 patients, 20 males and six females, mean age 37 y. o. average follow up 36 months. Right involved in þfteen cases. The mechanism of injury was a motor vehicle accident in 19 cases. Posterior type was the most frequent with 8 cases. In twelve cases it was reduced on initial presentation, so it was not possible to classify the type of dislocation. PCL was the most frequent damaged ligament (22 cases). In most cases (81%) TKD was reduced under general anesthesia and an early surgical repair was performed as each case required. The follow up assessment included the Lysholm scoring system. Results: Excellent or good results were obtained in 14 of 26 patients (55%). Fair or poor results were obtained in 12 of 26 cases (45%). In 5 of 12 cases the treatment was conservative. Peroneal nerve palsy (23%) and popliteal artery disruption (8%) were the most frequent complications. The most common residual symptom was instability compared with contralateral knee (85%). Conclusions: Early operative repair of all damaged structures was associated with the best functional result (55%). Non-operative treatment was associated with 100% unsatisfactory results.
