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.
ObjectiveTo explore the effectiveness of vacuum sealing drainage (VSD) combined with open bone graft for tibial traumatic osteomyelitis. MethodsBetween June 2007 and December 2012, 23 cases of tibial traumatic osteomyelitis were treated, including 15 males and 8 females with an average age of 32.5 years (range, 22-48 years). The time from injury to admission was 7-18 months (mean, 8.6 months). There was local bone scarring in 15 cases, the size ranged from 8 cm×4 cm to 15 cm×8 cm. The CT multi-planar reconstruction was carried out preoperatively. Eleven cases had segmental bone sclerosis with a length of 1.5 to 3.8 cm (mean, 2.6 cm); 12 cases had partial bone sclerosis with a range of 1/3 to 2/3 of the bone diameter. On the basis of complete debridement, infection was controlled by VSD; bone defect was repaired by VSD combined with open bone graft. After there was fresh granulation tissue, the wound was repaired by free skin graft or local skin flap transfer. ResultsNail infection occurred in 2 cases, which was cured after the use of antibiotics. The wound healed at the first stage after repairing. All cases were followed up 10-18 months (mean, 13.5 months). In 11 cases of segmental bone sclerosis, the infection control time was 7-14 days (mean, 8.8 days); the bone healing time was 32-40 weeks (mean, 34.4 weeks); and the frequency of VSD was 3-6 times (mean, 4.5 times). In 12 cases of partial bone sclerosis, the infection control time was 7-12 days (mean, 8.3 days); the bone healing time was 24-31 weeks (mean, 27.3 weeks); and the frequency of VSD was 3-5 times (mean, 3.6 times). Infection recurred in 1 case, and the patient gave up the therapy. No infection recurrence was observed in the other patients. ConclusionThe VSD combined with open bone graft is an effective method for the treatment of tibial traumatic osteomyelitis.
ObjectiveTo explore the effectiveness of open reduction and internal fixation through anterior and posterior approaches in treatment of open Tile type C pelvic fractures at early stage. MethodsBetween January 2009 and April 2012, 12 patients with open Tile C pelvic fractures were treated. There were 7 males and 5 females, aged 6-53 years (median, 31 years). Of 12 cases, 4 were classified as Tile type C1, 6 as Tile type C2, and 2 as Tile type C3; 5 were rated as Gustilo type Ⅱ and 7 as Gustilo type Ⅲ. The injury severity score was 18-57 (mean, 37.2). The interval of injury and admission ranged from 15 minutes to 3 days (median, 50 minutes). The debridement and external fixation were performed at first stage; then open reduction and internal fixation were used through anterior approach (reconstruction plate) and posterior approach (cannulated lag screws). The vacuum sealing drainage was performed during treatment until the wounds healed. ResultsDelayed healing of incison was obtained in 12 cases because of wound infection. Anatomical reduction or approximate anatomical reduction was achieved in all 12 cases. The patients were followed up 3-39 months (median, 18 months). No loosening of internal fixation or fracture displacement was observed during follow-up. The fracture healing time was 7-13 weeks (mean, 9.7 weeks). At last follow-up, according to the Matta standard, the outcome was excellent in 10 cases and good in 2 cases; according to Majeed score, the results were excellent in 9 cases, good in 1, and poor in 2. ConclusionEarly internal fixation operation of open Tile type C pelvic fractures can effectively restore the pelvic anatomical structure and stability, reduce the complication, and achieve satisfactory effectiveness.
