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.
【Abstract】 Objective To explore the cause of the perioprative period compl ication of scandinavian total anklereplacement(STAR) and to summarize the experience in the treatment and prevention. Methods From March 1999 toNovember 2006, 35 patients were given total ankle replacement(TAR) with STAR system. There were 19 males and 16 femaleswith an average age of 50.5 years (27 to 68 years), including 12 cases of posttraumatic arthritis, 8 cases of osteoarthritis and 15cases of rheumatoid arthritis. All patients had pain of ankle joint, swell ing and l imitation of joint motion. The disease coursewas 9-64 months. The curative effect was estimated by Kofoed total ankle scoring system. The mean preoperative ankle scorewas 29(6-48); the mean pain score was 18.3(0-35); the mean function score was 11.7(6-18); and the mean activity score was9.2(3-12). The type of all compl ications were record, and its cause, prevetion and treatment were analyszed. Results Thirtythreepatients achieved heal ing by first intention, 2 achieved delayed union because of infection. Twenty-eight patients werefollowed up 3-80 months (mean 43.5 months). Medial malleolus fracture occurred in 2 cases, unstable ankle joint introversion in2 cases, l imitation of ankle dorsiextension in 1 case and 1 case had hypoesthesia at intermediate dorsal skin of foot and 3rd-5thmetatarsal skin without obvious dysfunction; all were treated with symptomatic medication. The postoperative mean ankle scorewas 85.5 (58-95); the mean pain score was 48.3(35-50); the mean function score was 20.7(18-30); the mean activity score was17.2(16-20). There were statistically significant differences when compared with preoperative score(P lt; 0.01). The cl inical resultswere excellent in 16 patients, good in 9 patients and fair in 3 patients. The X-ray films showed no loosening and subsidence ofprosthesis. Conclusion Although STAR can retain the functions of the operated joint, it has its special compl ications. It isimportant to obey operation principle with proficient operative technique, to strictly control surgical indication and to intensifyperioperative period treatment so as to decrease the compl ications.
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 give a review and commentary on the treatment of acute foot and ankle injuries. Methods Based on the treatment experience and recent l iterature, a commentary on acute foot and ankle injuries were given, included the basic and cl inical research results, evaluation before operation, and treatment methods of the soft tissue and bone injuries. Results The treatment of acute foot and ankle injuries is still a hot point in orthopaedic surgery. Operative and non-operative treatment of fresh Achilles tendon rupture can achieve satisfactory results, and early weight-bearing do not increase the re-rupture rate. The time delay between first debridement and injury within 24 hours does not increase the infection rate. For the treatment of severe ankle fractures, attentions should be paid to the cartilage injury, and anatomic reduction, good real ignment, and the congruity recovery are very important. The treatment determination of calcaneal fractures depends on the fully understanding injury mechanisms, classifications, and treatment method. Talus fractures should try to be treated by experienced surgeons. Operation and fixation methods of Lisfranc injury depends on different injury types. Conclusion Acute foot and ankle injuries are common in cl inical, to achieve a satisfactory result in evaluation and treatment, it is important to have a fully evaluation of the injury type, and choose the best operation time and suitable treatment methods, as well as to fully understand the biomechanical characteristics of different regions.
ObjectiveTo investigate the effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions.MethodsBetween January 2012 and December 2016, 36 patients (36 feet) with ankle diseases underwent tibio-talo-calcaneal arthrodesis with parallel double thread headless compression screws via minimal anterior and lateral oblique incisions. There were 14 males and 22 females with an average age of 53.8 years (range, 18-76 years). There were 19 cases of left feet and 17 cases of right feet. There were 21 cases of talar necrosis, 7 cases of post-traumatic arthritis, 3 cases of rheumatoid arthritis, 2 cases of tuberculosis infection (inactive), 1 case of talar absence, 1 case of Charcot’s disease, and 1 case of pigmented villonodular synovitis of ankle and subtalar joints. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 53.7±2.5 and 5.9±0.2, respectively. The operation time was recorded and the wound healing and complications were observed. The bone healing was assessed by X-ray film and CT scanning. The function and pain of joint were evaluated by AOFAS and VAS scores.ResultsThe mean operation time was 49.8 minutes (range, 33-82 minutes). Incision infection occurred in 1 patient (2.8%) at 3 weeks after operation, and recovered after debridement. The other incisions healed by first intention without complications. Thirty-five patients were followed up with an average of 18.5 months (range, 12-29 months). Imaging examination showed fusion of the ankle and subtalar joints with an average fusion time of 10.9 weeks (range, 8-15 weeks). After 1 year, the AOFAS score (84.7±0.6) and VAS score (0.3±0.1) were significantly higher than preoperative scores (t=12.596, P=0.000; t=30.393, P=0.000).ConclusionIt is an effective surgical method of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions for end-stage ankle disease because of the less complications incidence and the higher postoperative fusion rate.
ObjectiveTo compare the effectiveness between modified Brostrom method repair and anatomical reconstruction anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) with single fibular tunnel for chronic lateral ankle instability. MethodsTwenty ankle specimens of fresh cadaver were dissected to provide the anatomic data of ATFL and CFL and to observe the neurovascular distribution. Between January 2008 and December 2011, 48 patients (48 ankles) with chronic lateral ankle instability were randomly divided to groups A and B (n=24). The direct repair of ATFL and CFL by modified Brostrom method was performed in group A, and anatomic doublebundle reconstruction of ATFL and CFL with free semitendinosus tendon autograft in group B. There was no significant difference in sex, age, body mass index, injury side, the causes of injury, interval of injury and operation, talar tilt angle, talus forward shift, ankle plantar flexion, dorsiflexion, valgus, varus, American Orthopaedic Foot and Ankle Society (AOFAS) score, and visual analogue score (VAS) between 2 groups (P>0.05). The image parameters and range of motion were compared between 2 groups after operation; AOFAS and VAS scores were used to evaluate the effectiveness. ResultsAll the incisions healed by first intention in 2 groups; no complication of nerve injury, infection, or skin necrosis was observed. All the patients were followed up 2-5 years (mean, 3.4 years); no subtalar stiffness or recurrent instability occurred during follow-up. The talar tilt angle, talus forward shift, AOFAS score, and VAS score were significantly improved at 2 years after operation when compared with preoperative ones in 2 groups (P<0.05). There was no significant difference in range of motion of ankle plantar flexion, dorsiflexion, and ankle valgus, and VAS score between 2 groups (P>0.05), but group B was significantly better than group A in the range of motion of ankle varus, talar tilt angle, talus forward shift, and AOFAS score (P<0.05). In the each item of AOFAS score, there was no significant difference in pain, abnormal gait, support and autonomic function, ankle flexion and extension, hind foot motion, and alignment between 2 groups (P>0.05), but group B was significantly better than group A in walking, maximum walking distance, and ankle stability (P<0.05). ConclusionThe described technique, which involves anatomic double-bundle reconstruction of the ATFL and CFL with single fibular tunnel and modified incision, is a viable option for treating lateral ankle instability, especially for young patients who need high stability and revision.
Objective To investigate effectiveness of the medial ankle branches propeller " Tennis racket-like” flap in repair of heel-ankle tissue defect. Methods Between June 2011 and June 2016, 50 patients with heel-ankle tissue defects were treated. There were 40 males and 10 females, with a median age of 35.6 years (range, 6–58 years). The defects were caused by trauma in 44 cases, scar deformity after trauma in 2 cases, chronic ulcer in 2 cases, and squamous cell carcinoma in 2 cases. The defects located at heel in 20 cases, ankle in 15 cases, and heel-ankle in 15 cases. The size of heel-ankle tissue defect ranged from 3.5 cm×2.0 cm to 13.0×10.0 cm. The course of disease ranged from 3 hours to 2 months (mean, 28 days). All wounds were repaired by the medial ankle branches propeller " Tennis racket-like” flap in a size of 3.8 cm×2.2 cm–13.4 cm×10.3 cm. The donor site was directly sutured in 5 cases or repaired by skin grafting in 45 cases. Results All flaps survived and wounds healed by first intention. Partial necrosis of skin grafting occurred in 1 case, and the wound recovered by change dressing. The other skin grafting survived and wounds healed by first intention. Forty-eight patients were followed up 12 months after operation. The appearance, sensory, and function of repaired heel-ankle flaps were satisfactory. Conclusion For heel-ankle tissue defect repair, the medial ankle branches propeller " Tennis racket-like” flap has advantages of the high survival rate, reliable blood supply, and sensory recovery.
Objective To investigate the clinical application of relaying lateral gastrocnemius artery perforator flap in reconstruction of the donor defect after distally sural flap transferring. Methods Between January 2014 and January 2016, 12 cases with foot and ankle defects were treated. There were 10 males and 2 females with an average age of 23.4 years (mean, 14-52 years). The injury was caused by motorcycle accident in 7 cases and traffic accident in 5 cases. The injury located at left limb in 7 cases and right limb in 5 cases. The size of soft tissue ranged from 10 cm×4 cm to 12 cm×6 cm. The disease duration was 2-84 hours (mean, 26.2 hours). The foot and ankle defects were reconstructed by distally sural flaps, then the flap donor sites were reconstructed with relaying lateral gastrocnemius artery perforator flap at the same stage. The size of distally sural flap ranged from 11 cm×5 cm to 13 cm×7 cm. The size of relaying flap ranged from 7 cm×4 cm to 10 cm×6 cm. Results All flaps survived uneventfully. All recipient sites and donor sites healed smoothly. No vascular crisis, wound dehiscence, or evident swelling occurred. All patients were followed up 6-14 months (mean, 12.4 months) with satisfied esthetic and functional results in recipient and donor sites. There were only linear scar on the donor sites. The color and contour was satisfying, the function of calf and foot were not affected. Conclusion The relaying lateral gastrocnemius artery perforator flap combined with distally sural flap is an idea choice to reconstruct foot and ankle defect, which can avoid donor site skin grafting, minimize donor site morbidity.
ObjectiveTo investigate the effectiveness of abdominal free flap carrying bilateral superficial circumflex iliac arteries for repairing large skin and soft tissue defects of foot and ankle.MethodsBetween June 2016 and June 2019, 15 patients with large skin and soft tissue defects of foot and ankle were admitted, including 10 males and 5 females with an average age of 30 years (range, 10-60 years). The causes of injury included 6 cases of traffic accident, 3 cases of machine strangulation, 3 cases of heavy object injury, 2 cases of fall, and 1 case of electric shock. The time from injury to admission was 3 hours to 10 days, with an average of 2 days. The wound located at dorsal foot in 5 cases, ankle in 6 cases, dorsal foot and ankle in 3 cases, and dorsal foot and sole in 1 case. All wounds were contaminated to varying degrees and accompanied by tendon and bone exposure, including 5 cases of extensive necrosis of the dorsal skin with infection. The area of defects ranged from 18 cm×6 cm to 25 cm×8 cm. There were 9 cases of foot and ankle fractures and dislocations, and 2 cases of foot and ankle bone defects. The wound was repaired with abdominal free flap carrying bilateral superficial circumflex iliac arteries. The area of the flaps ranged from 20 cm×8 cm to 27 cm×10 cm; the skin flaps were thinned under the microscope to make the thickness of 0.5-1.0 cm, with an average of 0.7 cm. All incisions at the donor site were sutured directly.ResultsDuring the operation, 1 case was replaced with an abdominal free flap carrying the superficial abdominal artery because the superficial iliac circumflex artery was thin and the superficial abdominal artery was thicker. The skin flaps of 15 cases survived smoothly, and the wounds healed by first intention; the donor incisions all healed by first intention. All patients were followed up 8-36 months, with an average of 15 months. The flap shape was satisfactory, with good texture and mild pigmentation of the flap edge, without obvious bloating, effect on shoe wear, or secondary surgical thinning of the flap. The linear scar left in the donor site and had no effect on hip joint movement. All fractures healed well, and the healing time ranged from 3 to 8 months, with an average of 6 months.ConclusionThe abdominal free flap carrying bilateral superficial iliac circumflex arteries has concealed donor site, with little damage, and can be sutured in one stage. The blood vessel is anatomically constant, with less variation, and reliable blood supply. It is one of the ideal flaps for repairing large skin and soft tissue defects of foot and ankle.
