ABSTRACT
Objective To explore the clinical effect of minimally invasive treatment of C type pilon fracture with single main plate combined with multiple planar screws for supporting fixation.Methods From January 2013 to March 2017,data of 22 patients treated by minimally invasive treatment with single main plate combined with multiple planar screws for supporting fixation were retrospectively analyzed.There were 17 males and 5 females,aged from 23 to 69 years (average,51.2 years).All cases were closed fractures involving fibula including weight hitting (5 cases),traffic accident (7 cases) and fall injury (10 cases).There were 3 cases of 43-C1 type,11 cases of 43-C2 type and 8 cases of 43-C3 type according to AO/OTA classification.According to the Rtiedi-Allg(o)wer classification,there were 5 cases of type Ⅱ and 17 cases of type Ⅲ.Complications were recorded postoperatively and the articular surface reduction was evaluated using the Burwell-Charnley score.At the last follow-up,Tornetta's pilon fracture clinical treatment outcome criteria was used to evaluate ankle joint function.Results All the patients were followed up for 13 to 25 months (average,17.3 months).There were 20 cases of anatomical reduction,1 case of fair reduction and 1 case of poor reduction according to the Burwell-Charnley score.All the 22 patients were healed with healing time of 3 to 6 months (average,4.8 months).The efficacy was evaluated according to the evaluation criteria of the clinical treatment results of pilon fracture by Tornetta:excellent in 8 cases,good in 10 cases,fair in 3 cases,and poor in 1 case.The excellent and good rate was 81.8％(18/22).All patients had no complications such as wound edge blistering,skin necrosis and infection.Among them,1 case of internal fixation rejection occurred,and the incision was well healed after removal of the internal fixation after 3 months.Conclusion Minimally invasive treatment of C type pilon fracture with single main plate combined with multiple planar screws for supporting fixation not only provides a better anatomical reduction of the articular surface,but also effectively reduces or even avoids incision complications.The long-term clinical results are satisfactory.
ABSTRACT
Objective To explore the efficacy of temporary titanium plate screwing for positional maintenance in reduction and internal fixation for displaced acetabular fractures.Methods A retrospective study was conducted of the 28 patients (28 hips) with displaced acetabular fracture who had been treated by open reduction and internal fixation from October 2013 to March 2016.They were 20 males and 8 females,aged from 24 to 68 years (average,42.3 years).The time from injury to surgery ranged from 7 to 21 days(average,14.5 days).According to the Letournel-Judet classification,there were 2 posterior column fractures,4 transverse fractures,5 posterior column plus posterior wall fractures,6 transverse plus posterior wall fractures,2 T-shaped fractures,3 anterior and posterior transverse fractures and 6 double column fractures.The posterior acetabular approach or combined anterior and posterior approach was used.In all the patients temporary titanium plate screwing was conducted to fix one side of the fracture so as to facilitate accomplishment of open reduction and internal fixation without losing the indirect anatomic reduction of the intraarticular fracture.After the open reduction and internal fixation was accomplished,the temporary screw fixation was removed in 26 patients but retained in 2 patients as needed.The reduction quality,complications and outcomes at the final follow-ups were recorded.Results All the 28 patients were followed up for 10 to 36 months (mean,15.6 months).By the Matta criteria,anatomical reduction was achieved in 26 cases,unsatisfactory reduction in one and poor reduction in one,yielding an anatomic reduction rate of 92.9％.By the improved Mere d'Aubigne & Postel criteria,the clinical outcomes at the final follow-up were excellent in 27 cases and good in one,yielding a good to excellent rate of 100％.Postoperatively,heterotopic ossification of different severities occurred in 11 cases but did not affect their joint function;transient paralysis of the sciatic nerve was reported in 6 cases but recovered 3 months after surgery.No complications like avascular necrosis of the femoral head or walking pain were observed during follow-ups.Conclusion Temporary fixation with titanium plate screws during open reduction and internal fixation for displaced acetabular fractures can effectively improve the reduction and fixation of the articular surface,leading to satisfactory short-term clinical outcomes.

ABSTRACT
Objective To investigate the clinical effect of minimally invasive single locking plate combined with multiplanar screw internal fixation on pilon fracture of distal tibia. Methods A retrospective case control study was conducted to analyze the clinical data of 51 patients with pilon fracture involving distal tibial articular surface admitted to 81th Group Military Hospital of the Army from January 2013 to August 2017. Among the patients, 20 patients including 15 males and five females, aged (37. 5 ± 9. 9)years were treated with closed traction reduction or open joint reduction through minimally invasive incision and single main locking plate combined with multiplanar screw placement ( study group) . There were 13 patients with type II and seven patients with type III according to Ru edi-Allgwer classification of fracture. In addition, 31 patients were treated with open reduction and multi-plate internal fixation (control group), including 25 males and six females, aged (43. 4 ± 11. 3) years. There were 20 patients with type II and 11 with type III according to Ru edi-Allgwer classification. The operation time, fracture healing time, postoperative complications were compared between the two groups. Burwell-Charnley imaging evaluation criteria were used to assess the quality of fracture reduction. At the last follow-up, ankle function was assessed by the American Orthopedic Foot and Ankle Society ( AOFAS) ankle-hind foot functional score. Results All 51 patients were followed up for 6-24 months, with an average of 16 months. The operation time was (82. 5 ± 19. 2)minutes in the study group and (127. 7 ± 40. 8)minutes in the control group (P<0. 05). The fracture healing time was (10. 8 ± 1. 6)weeks in the study group and (11.0 ±1.5) weeks in the control group (P>0.05). Local skin necrosis (not above the plate) occurred in two patients in the study group and in three patients in the control group, with the wounds being healed within 3 months after dressing change and vacuum sealing drainage ( VSD) . In the control group, one patient had severe infection and recovered after treatment of steel plate removal, debridement and irrigation, and external fixator fixation. Three patients in the control group had skin necrosis resulting in plate exposure, who received transferred skin flaps to cover the wound. The incidence of postoperative complications were 10％ (2/20) and 23％ in the study group and the control group, respectively (7/31) (P >0. 05), with the incidence of severe complications for 0 and 13％(4/31)(P<0. 05), respectively. According to Burwell-Charnley imaging evaluation criteria, 18 patients obtained anatomical reduction in the study group, one had unsatisfactory reduction and one had poor reduction, with satisfaction rate of 90％. In the control group, 29 patients obtained anatomical reduction and two had unsatisfactory reduction, with satisfaction rate of 94％ (P>0. 05). At the last follow-up, AOFAS ankle-hind foot function scores were excellent in 12 patients, good in five patients, fair in two patients and poor in one patient in the study group with excellence rate of 85％, while the scores were excellent in 20 patients, good in six patients, fair in three patients and poor in two patients in the control group, with excellence rate of 84％ (P>0. 05). Conclusion For pilon fracture of distal tibia, both minimally invasive single locking plate combined with multi-plate screw internal fixation and open reduction combined with multi-plate internal fixation have good reduction effect and satisfactory recovery of ankle function, but the former can significantly shorten the operation time and reduce the incidence of serious complications after operation.
