Résumé
Introduction: The study was conducted to evaluate clinical and functional outcomes of comminuted pilon of distal tibial fractures after surgical management and fixation by modalities available ranging from temporary external fixation, simple distal tibial plates to moderate plating system and intra medullary nails for fibula. Methodology: Total 24 cases with intraarticular distal tibial pilon fracture were randomly divided in to two group. One group was managed by one stage procedure and second group was operated by two stage procedure. Results: From this study we infer that patient who had undergone one stage procedure had shorter hospital stay. In present study we observed that arthrosis, superficial infection and arthritis was higher in two stage procedure. Assessed by Ovadia Beals Evaluation Score - Objective Evaluation as well as subjective evaluation. Furthermore, the rate of complications was also identical. However, functional outcome assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score revealed that the patients underwent one stage procedure had better functional outcome. Conclusion: Considering the better functional outcome and the shorter hospital stay, we preferred using one stage operative procedure in better skin condition, less soft tissue damage, closed fracture of type b and C AO/OTA Pilon fractures.

Objective To investigate the effect of locking compression plate(LCP)and anatomi-cal plate(AP)in the treatment of closed tibial Pilon fracture and its influence on lower limb functional re-habilitation.Methods A total of 82 patients with closed tibial Pilon fractures were randomly divided into LCP internal fixation group(LCP group,n=41)and AP internal fixation group(AP group,n=41).The perioperative indexes and the incidence of postoperative complications were compared between the two groups.The ankle function was evaluated by American Orthopaedic Foot & Ankle Society Ankle Hindfoot Scale(AOFAS-AHS),the lower limb function was evaluated by Lysholm scale,the serum levels of inter-leukin-1β(IL-1β)and interleukin-6(IL-6)were detected.Results The intraoperative blood loss,opera-tion time,hospitalization time,first ground time,fracture healing time were(103. 34 ± 11. 34)ml, (47.65 ± 7.89)min,(9.01 ± 2.23)d,(5.31 ± 1.27)d,(16.23 ± 2.12)weeks in LCP group respective-ly,the AP group were(132.25 ± 34.41)ml,(60.54 ± 11.23)ml,(11.43 ± 2.57)d,(6.23 ± 1.56)d, (23.12 ± 3.31)weeks,respectively.The LCP group were significantly lower than AP group(P<0.05);The excellent rate of ankle function of LCP group was 95.12%,significantly higher than 82.93% in the AP group(P<0.05);The incidence of postoperative complications was 4.88% in the LCP group,which was significantly lower than 29.27% in the AP group(P<0.05);At 3,6 and 12 months after operation, the AOFAS-AHS scores in the LCP group were(69.52 ± 4.18)points,(78.89 ± 6.73)points and (87.23 ± 6.34)points respectively,the AP group were(65.09 ± 4.45)points,(70.13 ± 5.34)points and (76.69 ± 5.91)points respectively,the LCP group were significantly higher than AP group(P<0.05);At 3,6 and 12 months after operation,the Lysholm scores were(77.12 ± 6.43)points,(82.12 ± 7.81)points and(86.19 ± 8.11)points in LCP group,AP group were(67.25 ± 5.56)points,(72.21 ± 7.23)and (77.12 ± 7.54)points,the LCP group was significantly higher than AP group(P<0.05).At 3 d and 4 weeks after operation,the serum levels of IL-1β in LCP group were(0.37 ± 0.09)pg/ml,(0.19 ± 0.06) pg/ml,while in AP group were(0.45 ± 0.13)pg/ml,(0.27 ± 0.09)pg/ml;the serum levels of IL-6 in LCP group were(201.23 ± 30.12)ng/L,(102.23 ± 25.21)ng/L,while in AP group were(246.71 ± 41.23)ng/L,(158.95 ± 25.21)ng/L.The AP group were significantly lower than those in AP group(P<0.05).Conclusion LCP and AP in treatment of closed tibial Pilon fractures have a significant effect,but LCP can reduce the surgical trauma,shorten the operation time and postoperative recovery time,to a cer-tain extent,improve the ankle and lower limb function,and reduce the postoperative fixation fracture heal-ing and other complications.
Résumé
Objective To explore the operative method of open distal tibial pilon fractures, and to evaluate the outcome of ankle joint function postoperatively. Methods From March 2003 to March 2007, 24 patients with open Pilon fractures were treated with one-stage open reduction and internal fixation (18 males and 6 females) . The average age was 37. 6 years (14 ～ 53 years) . All 24 patients had open fracture, 12 of whom combined fibular fracture. According to AO comprehensive classification system, the fractures was classified as C1 in 4, C2 in 9, and C3 in 11. According to Gustilo-Anderson classification method, the fracture was classified as Type Ⅰ in 3, Type Ⅱ in 5, Type Ⅲ A in 4, Type Ⅲ B in 10, and Type Ⅲ C in 2. All tibial pilon fractures were treated by radical debridement, one - stage open reduction and internal fixation. Soft tissue defection was covered by a vascularized flap and continually washed by pipes under the flap. Results All patients were followed-up at an average of 2. 3 years(1～3.8 years) after the surgery. All the fractures healed at an average of 22. 3 weeks (16 ～54 wk) postoperatively. According to the scoring system of Con-roy, 17 were excellent (62. 5%), 4 good (25%), and 3 poor (12.5%), The excellence rate was 87.5% . According to the ankle score of Teeny and Wiss, there were 11 excellent (37. 5%), 7 good (37.5%), 3 fair (16.7%), and 3 poor (8.3%) and the excellence rate was 75% . Conclusion One-stage management for open Pilon fracture has the advantages of fewer complications, lower infectious rate, and better ankle joint function.
