Objective To summarize the clinical effects of the repairing methods for deep wounds of the foot and ankle. Methods From March 2002 to June 2006, 49 patients with skin and deep tissue defects of the foot and ankle underwent the repairing treatment. Of them, 36 were males and 13 were females, aged 16 to 67 years( 39 years on average). The causes of injuries included mangled injury in 24 cases, high fall injury in 9 cases, cut injury in 7 cases, malignant soft tissue tumor in 5 cases, decubital ulcer in 2 cases, and electric burn in 2 cases. Of the 49 cases, 19 were in left side and 30 in right side. The defect size of skin ranged from 3 cm×2 cm to 20 cm×15 cm and deep tissue injuries were accompanied by defects of tendon and ligament in 24 cases, by damage of joint in 12 cases, and by bone defect in 9 cases, and 35 of them had infections, and 2 of them had diabetes of stage 2. The time between the injury and surgery ranged from 4 hours to 1 year.The wounds were repaired separately by local flap(3 cm×3 cm to 6 cm×4 cm) in 15 cases, local island flap(8 cm×5 cm to 12 cm×7 cm) in 25 cases, free flap(15 cm×11 cm to 24 cm×17 cm) in 4 cases, and cross leg flap(5 cm×4 cm to 8 cm×6 cm) in 5 cases. In 24 cases of defects of tendon and ligament, 15 underwent the reconstruction in one-stage operations,9 in two-satge operation.In 9 cases accompanied by bone defect, twostage bone grafting (12-64 g) was given after wound healed. Results All of the 49 flaps survived. Fortysix healed by the first intention and 3 with distal edge necrosis healed after skin grafting. Two patients with sinus formation healed after 68 months of dressing change. All the cases were followed up 6 months to 3 years, and all the flaps were well developed, the functions of the foot and ankle were satisfactory. Conclusion It can get an excellent result of appearance and function recovery repairing deep wounds of the foot and ankle with proper flaps in earlier time.
OBJECTIVE: To investigate the clinical effects of the microsurgical treatment for the skin-degloving injury of the whole hand or foot. METHODS: From March 1984 to October 2001, we treated 6 cases of skin-degloving injury of the whole hand and foot. In 2 cases of skin-degloving hands, one was treated with free great omentum transplantation plus skin graft, the other with pedical abdominal S-shaped skin flap as well as mid-thick skin graft. In 4 cases of skin-degloving injury of the foot, 2 cases was repaired with free latissimus dosi musculocutaneous flap, 1 case with distall-based lateral skin flap of the leg and 1 case with free tensor fasciae latae muscle flap. The flap size ranged from 7 cm x 9 cm to 22 cm x 15 cm. One case was operated on the emergency stage, the other 5 cases on the delayed stage. The delayed time ranged from 2 to 14 days with an average of 6.6 days. RESULTS: All the flaps survived. After 1-2 year follow-up, the appearance and function of the hand and the foot were good. CONCLUSION: Microsurgery technique in repairing skin-degloving injury of the whole hand and foot can achieve good results. The keys to success are thorough debridement of the recipient area, appropriate selection of the donor site, good vascular anastomosis and active postoperative rehabilitation.
Objective To investigate the clinical curative effect of distal phalanx of great toe and soft tissue orthopaedics for treatment of obstinateingrown nail. Methods From October 1997 to May 2006,31 patients(38 nails) suffering from obstinate ingrown nail were treated by the distal phalanx of great toe and soft tissue orthopaedics. There were 23 males(27 nails) and 8 females(11 nails) with an average age of 17.5 years(12-28 years). The disease course was 2years and 1 month to 14 years(average, 31-6 months). At the same time, thirty-eight patients with diseases of feet were selected randomly as controls. The depth of the nail groove was measured.The X-ray films were taken to calculate the rate of upward projection of tuberosity (r). Results Thedepth of the nail and r value of 31 patients were 2.87±0.31 mm and 0.149±0.013，respectively. There were statistically significant differences when compared with control group（1.06±0.10 mm and 0.060±0.019）（Plt;0.01）. Thirty patients(37 nails) had a primary healing; 1 patient(1 nail) had a delayed healing. Twenty-nine patients(36 nails) were followed up for 8 to 29 months(average, 21 months). The appearance of the nail was satisfactory. No relapse occurred in all patients. Conclusion The upward projection of tuberosity of distal phalanx of great toe and deepened nail groove are the most important anatomical causes for ingrown nail. The distal phalanx of great toe and soft tissue orthopaedics is aneffective treatment for obstinate ingrown nail.
Objective To explore the clinical effect of the lower rotating point super sural neurocutaneous vascular flap on the repair of the softtissue defects in the ankle and foot. Methods From May 2001 to February 2006, 24 patients with the soft tissue defects in the ankle and foot were treated with the lower rotating point super sural neurocutaneous vascular flaps. Among the patients, 15 had an injury in a traffic accident, 6 were wringedand rolled by a machine, 1 was frostbited in both feet, 2 were burned, 25 had an exposure of the bone and joint. The disease course varied from 3 days to 22 months; 19 patients began their treatment 3-7 days after the injury and 5 patients were treated by an elective operation. The soft tissue defects ranged in area from 22 cm × 12 cm to 28 cm × 12 cm. The flaps ranged in size from 24 cm × 14cm to 30 cm × 14 cm, with a range up to the lower region of the popliteal fossa. The rotating point of the flap could be taken in the region 1-5 cm above thelateral malleolar. The donor site was covered by an intermediate thickness skingraft. Results All the 25 flaps in 24 patients survived with asatisfactory appearance and a good function. The distal skin necrosis occurred in 1 flap, but healing occurred after debridement and intermediate thickness skin grafting. The follow-up for 3 months to 5 years revealed that the patients had a normal gait, the flaps had a good sense and a resistance to wearing, and no ulcer occurred. The two point discrimination of the flap was 5-10 mm. Conclusion The lower rotating point super sural neurocutaneous vascular flap has a good skin quality, a high survival rate, and a large donor skin area. The grafting is easy, without any sacrifice of the major blood vessel; therefore, it is a good donor flap in repairing a large soft tissue defect in the ankle and foot.
Objective To review the progress in clinical and biomechanical study on soft tissue reconstruction of adult-acquired flatfoot deformity (AAFD). Methods The recent original articles of soft tissue repair and tendon transfer for AAFD were extensively reviewed. Results The soft tissue procedures for AAFD can be divided into two components: static restoration of medial column stability and dynamic reconstruction of the posterior tibial tendon. The most important static structure to be repaired for AAFD is the spring ligament. On the other hand, various methods can be used for dynamic reconstruction. The flexor digitorum longus transfer is widely used, but results of biomechanical studies do not support the advantage of this method. For patients having normal function of the posterior tibial muscle, the Cobb procedure may be more suitable. Conclusion The soft tissue reconstruction procedures of AAFD should be chosen individually based on the stage and type of the deformity.
Objective To share the experience of the diagnosis and treatment of children with hand-foot-mouth disease. Methods We retrospectively analyzed 31 children with hand-foot-mouth disease in our hospital from April 2007 to June 2007 in terms of epidemiology, clinical features, treatment and prognosis. Results The average age of the children was 2.8 years, and 20 out of the 31 cases were from nurseries and kindergartens. Eighteen had clear contact history. Typical signs and symptoms, including oral ulcerative herpes and blister-like rash in extremities, were found in all cases. All the children were cured after timely diagnosis and early treatment with ribavirin, without any severe complications. Conclusion Timely treatment based on early diagnosis and considerate care are important for children with hand-foot-mouth disease. Nurseries, kindergartens and primary schools should attach great importance to relevant prophylaxis and isolation. These are essential for reducing the occurrence and prevalence of this disease.
