OBJECTIVE: To investigate the effect of soft tissue repairing at different times on the union of type III b tibial fracture. METHODS: From January 1987 to January 1999, seventy-six type III b tibial fractures were divided into 3 groups: early group(0 to 7 days), subacute group(8 to 30 days), late group(more than 30 days) according to the time of soft tissue repairing. The morbidity rates of complications such as infection, nonunion as well as the time to union were compared respectively. RESULTS: Followed up for 10 to 36 months (averaged 24 months), the infection and nonunion rates of early group were lower than that of subacute and late groups(P lt; 0.01), the average time of fracture union of early group was less than that of subacute and late groups. CONCLUSION: Early soft tissue repairing can decrease the complications and the time to union of Type III b tibial fracture obviously. The time of "early" should be limited in one week and as soon as possible.
Objective To investigate the effect of transplantation of the cutaneous iliac flap on repairing bone and soft tissue defect of metatarsal. Methods From October 1999 to December 2003, the cutaneous iliac flap was designed for the repair of bone and soft tissue defect of metatarsal in 4 male patients, whose ages ranged from 26 to 47, with skin graft for the coverage of the iliac flap. The duration of injury ranged from 1 to 5 months. The length of the defect ranged from 4 to 7 cm and the defect area ranged from 5 cm×3 cm to 9 cm×5 cm. Results One week after transplantation, complete survival of iliac flap was observed in 3 cases and partial survival in 1 case (but later proved survived). Callus was seen 1 month after transplantation and Kwires were removed 4months after transplantation. Patients were followed up for 5 to 24 months. There were no ulcers. The ability of walking and bearing was satisfying as well asthe function and shape. Conclusion With satisfying restoration of function and shape, transplantation of the cutaneous iliac flap with skin graft is an alternative to treat bone and soft tissue defect of metatarsal with one stage surgery.
OBJECTIVE To introduce the clinical application of the expanded graft from scalp in the repair of cicatricial baldness in children. METHODS 45 cases with baldness following burn from 1988 to 1998 were reported. All of these patients (age ranged from 5-11 years) were treated by soft tissue expander. RESULTS 5 cases were followed up for 1-2 years, the clinical results showed that the result from the graft of scalp expansion was satisfactory, and the long-term follow-up revealed that the hair in expended area and that in normal area was almost the same except the orientation of hair distribution had some difference. CONCLUSION The head scalp expansion might be the first choice in the repair of cicatricial baldness following burn.
Objective To evaluate the effectiveness of soft tissue reconstruction after resection of musculoskeletal tumor and to discuss the strategy of soft tissue reconstruction. Methods Between June 2003 and December 2010, 90 patients with musculoskeletal tumor underwent tumor resection and soft tissue reconstruction. There were 59 males and 31 females with a median age of 37.2 years (range, 9-85 years), including 52 bone tumors and 38 soft tissue tumors. One stage reconstruction of soft tissue was performed after tumor resection in 75 cases; reconstruction of soft tissue was performed after debridement in 7 cases of wound dehiscence; and two stage reconstruction of soft tissue was performed after debridement and vacuum sealing drainage placement in 8 cases of infected wounds. The gastrocnemiums flap was used in 40 cases, the latissimus dorsi myocutaneous flap in 6 cases, rectus abdominis myocutaneous flap in 4 cases, gluteus maximus musculocutaneous flap in 1 case, pectoralis major muscle flap in 1 case, cross-abdominal flap in 1 case, local transfer flap in 27 cases, pedicled flaps in 5 cases, and skin grafts in 5 cases. The size of the flap ranged from 6.5 cm × 4.5 cm to 21.0 cm × 9.0 cm. Results Eighty-seven flaps survived, and incisions healed by first intention in 81 cases. In 6 cases of healing by second intention, 2 had partial flap necrosis, which was cured by dressing change; 3 had delayed healing; 1 had mild infection, which was cured after conservative treatment. Wound of donor site healed primarily, and the grafted skin survived. Seventy-three patients were followed up 10-102 months (mean, 36.1 months). Local tumor recurrence was observed in 6 patients, who received second resection at 2-27 months (mean, 8.2 months) after operation. Thirteen patients dead of primary disease at 6-34 months (mean, 19.2 months) after operation. Conclusion The defects caused by resection of musculoskeletal tumor require soft tissue reconstructions. Optimal reconstruction can enhance wound closure, decrease incidence of wound complication, preserve limb function.
Objective To review the research progress of the skin flap, fascial flap, muscle flap, and myocutaneous flap for repairing soft tissue defects around the knee so as to provide information for clinical application. Methods Domestic and abroad literature concerning the methods of soft tissue repair around the knee in recent years was reviewed extensively and analyzed. Results Fascial flaps meet the requirements of thin, pliable, and tough skin in the soft tissue repair around the knee. Myocutaneous flaps and muscle flaps have more abundant blood supply and anti-infection function. Free skin flaps are the only option when defects are extensive and local flaps are unavailable. Conclusion Suitable flaps should be chosen for soft tissue repair around the knee according to defect position, depth, and extent. Fascial flaps may be selected as the first flaps for defects repair because of excellent aesthetic results and less injury at the donor site.
Objective To explore the technique of the soft tissue balancing inthe total knee arthroplasty (TKA) for the patients with the knees of varus deformity and flexion contracture. Methods From January 2001 to December 2005, 86 patients (19 males, 67 females; age, 57-78 years;average, 66 years) with the knees of varus deformity and flexion contracture underwent primary TKA and the balancing of the soft tissues. All the patients had suffered from osteoarthritis. The unibilateral affection was found in 68 patients and the bilateral affection in 18. The varus deformity angle was averaged 12.3° (range, 6-34°). The soft tissue varus accounted for 56.7% and the bony varus accounted for 43.3%. The flexion contracture lt; 10° was found in 21 knees, 10-19° in 45 knees, 20-29° in 22 knees, and gt;30° in 16 knees, with an average angle of 18.9°. Results The flexion contractures were improved. Before operation the average angle ofthe flexion contracture was 18.9° but after operation only 4 patients had a residual flexion contracture of 5° and the remaining patients had a complete correction. The follow-up for 37 months (range, 6-72 months) in all the patients revealed that only 6 patients had a residual flexion contracture of 5-10° and the others had a full extension. Before operation the average varus angle was 12.3°(range, 6-34°) and the average tibiofemoral angle was 174.7° (range, 70.3-175.6°), but after operation the residual varus angle gt; 3° was only found in 2 patients. The complications occurring during operation and after operation were found in 6 patients, injuries to the attachment of the medial collateral ligaments in 2, patellar clunk syndromes in 2, cerebral embolism in 1, and lacunar infarction in 1, with no nerve disorders left after the medical treatment. No skin necrosis, the cut edge infection or deep infection occurred. Conclusion The balancing of the soft tissues is a major management for correction of the varus deformity and the flexion contracture. The proper balancing of the softtissues can achieve an obvious recovery of the function and correction of the varus deformity after TKA.
Objective To study the repair and function reconstruction of complex soft tissue defect of posterior of hand and forearm. Methods From May 2001 to November 2003, 8 cases of soft tissue defect of posterior of hand and forearm were repaired with thoracico abdominal flaps with hilum for primary stage. The tendon transplantation and allogeneic tendon function reconstruction of hand were performed for secondary stage. The range of the flap was 9 cm×15 cm to 12cm×38 cm. Allogeneic tendon amounted to 6.Results All the flaps survived. The flap countour was good. The results of allogeneic tendon transplantation were satisfactory and the function of hand was good. Conclusion Repairing complex soft tissue defect of posterior of hand and forearm and reconstructing hand function by use of thoracico abdominal flaps with hilum and transplantation of allogeneic tendon have the satisfactory clinical results.
Objective To explore the feasibil ity, indications, and effects of vacuum seal ing drainage (VSD) combined with flaps for repairing skin and soft tissue defects of lower l imbs. Methods From June 2006 to November 2009, 15 patients with skin and soft tissue defects of lower l imbs were treated with VSD combined with flaps (VSD group, n=5) and only flaps (non-VSD group, n=10). In VSD group, there were 3 males and 2 females with an average age of 46 years (range, 32-69 years), including 3 cases of traffic accident injury, 1 case of skin necrosis after amputation, and 1 case of plate exposureafter operation. The locations were lower leg in 1 case, ankle in 2 cases, dorsum of foot in 1 case, and forefoot in 1 case. The defect size ranged from 6.5 cm × 6.0 cm to 23.0 cm × 17.0 cm. The disease course ranged from 2 hours to 2 months. In non- VSD group, there were 5 males and 5 females with an average age of 50 years (range, 23-58 years), including 6 cases of traffic accident injury, 1 case of crush injury in earthquake, 1 case of osteomyel itis, and 2 cases of plate exposure after operation. The locations were lower leg in 1 case, ankle in 3 cases, forefeet and dorsum of feet in 4 cases, and heel in 2 cases. The defect size ranged from 4 cm × 4 cm to 20 cm × 12 cm. The disease course ranged from 1 hour to 2 months. There was no significant difference in general data between 2 groups (P gt; 0.05). Results In VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (11.8 ± 9.5), (35.4 ± 28.3), and (47.2 ± 35.8) days, respectively; the size of flap was (232.8 ± 142.0) cm2; and the infection rate after VSD-use was 0. In non-VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (25.8 ± 12.4), (33.9 ± 28.1), and (59.7 ± 32.4) days, respectively; the size of flap was (97.3 ± 93.6) cm2; and the infection rate after 8 to 14 days of regular therapy was 80%. There were significant differences in the preoperative hospital ization days and the size of flap between 2 groups (P lt; 0.05). All flaps were al ive except 3 partial necrosis (1 case in VSD group, 2 cases in non-VSD group). The 3 flaps healed by skin grafting and suturing. The donor sites healed by first intention. All patients were followed up 5-41 months (22.1 months on average). All flaps were good in color, texture, and wear abil ity. Conclusion It is effective to apply VSD combined with proper flap to repair skin and soft tissue defects of lower l imbs, which can cut down infection rate, improve blood supply, shorten the preoperative hospital ization days, and facil itate heal ing, but whether it can shorten the postoperative hospital ization days and total hospital ization days need further research.
OBJECTIVE: To summarize the application of cross-arm skin flaps with lateral antebranchial cutaneous nerve in repair of soft tissue defect. METHODS: From March 1996 to March 2001, 37 cases of soft tissue defect at fingertips were repaired by cross-arm skin flaps with lateral antebranchial cutaneous nerve, 1.5 cm x 1.5 cm to 3.5 cm x 4.0 cm in size. All of the cases were followed up for 3-48 months with routine evaluation of the wound and the function of hands. RESULTS: All of the flaps survived and the wound achieved primary healing. The sensation and shape of hands recovered well. CONCLUSION: It’s a good choice to repair soft tissue defect at fingertips by cross-arm skin flaps with lateral antebranchial cutaneous nerve.
ObjectiveTo evaluate the effectiveness of one stage vacuum sealing drainage (VSD) combined with bi-pedicle sliding flap transplantation in repairing open tibiofibular fracture and soft tissue defects of the lower leg. MethodsTwenty-five patients with open tibiofibular fracture and soft tissue defects of the lower leg were treated by VSD combined with bi-pedicle sliding flap transplantation between January 2012 and July 2014. There were 18 males and 7 females, aged 12-65 years (mean, 35.2 years). The injury causes included traffic accident injury (20 cases), falling injury from height (3 cases), and heavy pound injury (2 cases). The left side was involved in 14 cases, the right side in 8 cases, and both sides in 3 cases. According to Gustilo classification, injury was rated as type II (6 lower extremities), type III a (19 lower extremities), and type III b (3 lower extremities). The anterior tibial defect area after debridement ranged from 6 cm×3 cm to 12 cm×5 cm. The course of injury and admission was 1-18 hours (mean, 4.5 hours). An anterior tibial bi-pedicle sliding flap of 24 cm×6 cm to 48 cm×8 cm was designed to cover the wound and tibia fracture was fixed with minimally invasive internal fixation. After suturing the anterior tibial wound without tension, the flap was transferred forward. The exposed fibula was fixed with reconstruction plate. The remained wound was covered by VSD. Continuously antibiotic saline irrigation was applied postoperatively. After 15 days, the VSD dressing was removed and free skin graft was used to cover the remained wound. ResultsAfter the VSD dressing was removed, the wounds and tension-reduced wound of 18 lower extremities completely healed. Unhealing wounds were covered by skin graft in 9 lower extremities. Infection occurred in 1 lower extremity and was cured after treated with antibiotics. All the wounds healed and flaps survived. The patients were followed up 6-24 months (mean, 18 months). The fractures union was confirmed by X-ray and the average union time was 3.2 months (range, 2.5-5 months). ConclusionThe application of one stage VSD combined with bi-pedicle sliding flap transposition is a simple and safe treatment regimen for Gustilo type II-IIIa open tibiofibular fracture and soft tissue defects of the lower leg. It has the advantages of few complications and low costs, short hospitalization, and good effectiveness.
