ObjectiveTo compare the clinical results between percutaneous poking reduction fixation and open reduction and internal fixation for the displaced Sanders Ⅱ type calcaneal fractures. MethodsA retrospective analysis was made on the clinical data of 122 patients with Sanders Ⅱ type calcaneal fractures between May 2007 and May 2012, who accorded with the inclusion criteria. The closed reduction and percutaneus Kirschner wire fixation were used in 61 patients (closed group), and open reduction and internal fixation were used in 61 patients (open group). There was no significant difference in gender, age, fracture side, weight, height, body mass index, the causes of injury, the fracture type, Böhler angle, Gissane angle, and the time from trauma to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, hospitalization days, wound complications, fracture healing time, American Orthopaedic Foot and Ankle Society (AOFAS) score, and radiographic results were compared between 2 groups. ResultsThe operation time, intraoperative blood loss, and hospitalization days in closed group were significantly less than those in open group (P<0.05). There was no deep infections in both group; wound dehiscence, skin flap necrosis, and wound infection occurred in 3 patients, 2 patients, and 1 patient of the open group, no wound complication happened in closed group, and there was significant difference in the incidence of wound complications between 2 groups (P=0.027). The patients were followed up 24-68 months (mean, 38.7 months) in the closed group and 26-66 months (mean, 38.7 months) in the open group. There was no significant difference in the fracture healing time between 2 groups (t=-1.562, P=0.121). The Böhler angle and Gissane angle at last follow-up were significantly improved when compared with preoperative angle in the closed group (t=-27.929, P=0.000; t=-26.351, P=0.000) and the open group (t=-32.565, P=0.000; t=-25.561, P=0.000), but there was no significant difference between 2 groups (P>0.05). AOFAS score showed no significant difference between 2 groups (t=-0.492, P=0.624). ConclusionFor the displaced Sanders Ⅱ type calcaneal fractures, the use of closed reduction and percutaneus Kirschner wire fixation or open reduction and internal fixation can both obtain satisfactory clinical function and radiographic results, but the former has the advantage of less trauma, shorter hospitalization time, and fewer wound complications.
Objective To investigate the effectiveness of a new tibial plateau posterolateral column universal locking anatomical plate (hereinafter referred to as “new universal locking anatomical plate”) in the treatment of tibial plateau posterolateral column fractures. Methods Between October 2020 and December 2021, 14 patients with tibial plateau posterolateral column fracture were treated with a new universal locking anatomical plate. There were 7 males and 7 females with an average age of 59 years ranging from 29 to 75 years. There were 5 cases on the left side and 9 cases on the right side. The causes of injury included falling from height in 5 cases, traffic accident in 7 cases, and other injuries in 2 cases. The time from injury to operation ranged from 3 to 10 days, with an average of 6 days. According to Schatzker classification, there were 4 cases of type Ⅱ, 8 cases of type Ⅴ, and 2 cases of type Ⅵ. All fractures involved the posterolateral tibial plateau. Three column classification: two columns (anterolateral column+posterior column) in 4 cases, three columns in 10 cases. The operation time, intraoperative blood loss, fracture healing, and complications were recorded. The reduction of tibial plateau fracture was evaluated by Rasmussen radiographic score, and the recovery of knee function was evaluated by Hospital for Special Surgery (HSS) score. Results All 14 cases completed the operation successfully. The operation time was 95-180 minutes, with an average of 154 minutes, and the intraoperative blood loss was 100-480 mL, with an average of 260 mL. All patients were followed up 6-19 months, with an average of 12.5 months. All fractures healed, and the healing time was 15-24 weeks, with an average of 18.7 weeks. During the follow-up, there was 1 case of common peroneal nerve palsy and 1 case of traumatic osteoarthritis. There was no other complication such as vascular injury, incision infection, deep venous thrombosis of lower limbs, heterotopic ossification, bone nonunion, and failure of internal fixation. The reduction of tibial plateau fractures was good immediately after operation, and the Rasmussen radiological score was 10-18, with an average of 15.7; 3 cases were excellent, 10 cases were good, and 1 case was fair, with an excellent and good rate of 92.9%. The scores and grades of HSS at 3 months after operation and at last follow-up significantly improved when compared with those before operation (P<0.05). There was no significant difference between 3 months after operation and last follow-up (P>0.05).Conclusion For the fractures involving the posterolateral column of the tibial plateau, the new universal locking anatomical plate can provide strong fixation, satisfactory postoperative fracture reduction, and good recovery of knee function.
ObjectiveTo introduce the surgery method to reset and fix tibial plateau fracture without opening joint capsule, and evaluate the safety and effectiveness of this method. MethodsBetween July 2011 and July 2013, 51 patients with tibial plateau fracture accorded with the inclusion criteria were included. All of 51 patients, 17 cases underwent open reduction and internal fixation without opening joint capsule in trial group, and 34 cases underwent traditional surgery method in control group. There was no significant difference in gender, age, cause of injury, time from injury to admission, side of injury, and types of fracture between 2 groups (P>0.05). The operation time, intraoperative blood loss, incision length, incision heal ing, and fracture healing were compared between 2 groups. The tibial-femoral angle and collapse of joint surface were measured on X-ray film. At last follow-up, joint function was evaluated with Hospital for Special Surgery (HSS) knee function scale. ResultsThe intraoperative blood loss in trial group was significantly less than that in control group (P<0.05). The incision length in trial group was significantly shorter than that in control group (P<0.05). Difference was not significant in operation time and the rate of incision heal ing between 2 groups (P>0.05). The patients were followed up 12-30 months (mean, 20.4 months) in trial group and 12-31 months (mean, 18.2 months) in control group. X-ray films indicated that all cases in 2 groups obtained fracture heal ing; there was no significant difference in the fracture healing time between 2 groups (t=1.382, P=0.173). On X-ray films, difference was not significant in tibial-femoral angle and collapse of joint surface between 2 groups (P>0.05). HSS score of the knee in trial group was significantly higher than that of control group (t=3.161, P=0.003). ConclusionIt can reduce the intraoperative blood loss and shorten the incision length to use open reduction and internal fixation without opening joint capsule for tibial plateau fracture. Traction of joint capsule is helpful in the reduction and good recovery of joint surface collapse. In addition, the surgery without opening joint capsule can avoid joint stiffness and obtain better joint function.
Objective To investigate the effectiveness of joystick technique assisted closed reduction and cannulated screw fixation in the treatment of femoral neck fracture. Methods Seventy-four patients with fresh femoral neck fractures who met the selection criteria between April 2017 and December 2018 were selected and divided into observation group (36 cases with closed reduction assisted by joystick technique) and control group (38 cases with closed manual reduction). There was no significant difference in gender, age, fracture side, cause of injury, Garden classification, Pauwels classification, time from injury to operation, and complications (except for hypertension) between the two groups (P>0.05). The operation time, intraoperative infusion volume, complications, and femoral neck shortening were recorded and compared between the two groups. Garden reduction index was used to evaluate the effect of fracture reduction, and score of fracture reduction (SFR) was designed and was used to evaluate the subtle reduction effect of joystick technique. ResultsThe operation was successfully completed in both groups. There was no significant difference in operation time and intraoperative infusion volume between the two groups (P>0.05). All patients were followed up 17-38 months, with an average of 27.7 months. Two patients in the observation group received joint replacement due to failure of internal fixation during the follow-up, and the other patients had fracture healing. Within 1 week after operation, the Garden reduxtion index of the observation group was better than the control group; the SFR score of the observation group was also higher than that of the control group; the proportion of femoral neck shortening within 1 week after operation and at 1 year after operation in the observation group were lower than those in the control group. The differences of the above indexes between the two groups were significant (P<0.05). ConclusionThe joystick technique can improve the effectiveness of closed reduction of femoral neck fractures and reduce the incidence of femoral neck shortening. The designed SFR score can directly and objectively evaluate the reduction effect of femoral neck fracture.
Objective To explore the effectiveness of limited incision, poking reduction, and simple internal fixation in the treatment of collapsed fractures of the posterolateral tibial plateau. Methods Between October 2010 and January 2016, 16 patients with collapsed fractures of the posterolateral tibial plateau underwent posterolateral incision, poking reduction, and simple internal fixation. There were 10 males and 6 females with the age of 22-63 years (mean, 43.5 years). The injury was caused by falling in 5 cases, traffic accident in 7 cases, and falling from height in 4 cases. All cases had closed fractures. The left knee was involved in 9 cases and the right knee in 7 cases. The injury-to-admission time was 2 hours to 3 days (mean, 10 hours). X-ray films showed that the articular surface collapsing was more than 2 mm. According to Schatzker criteria, 6 cases were rated as type II and 10 cases as type III. Twelve cases had fracture of fibular head. The incision length, operation time, intraoperative blood loss, and incision healing were recorded; fracture healing was observed, and tibial plateau angle and posterior slope angle were measured on X-ray films; loss of articular surface reduction was observed by CT scan; and American Hospital for Special Surgery (HSS) score was used to evaluate the knee joint function. Results The incision length was 7-10 cm (mean, 8.6 cm); operation time was 35-55 minutes (mean, 46 minutes); intraoperative blood loss was 10-35 mL (mean, 28 mL). Primary healing of incision was obtained. Skin pain occurred in 1 case at 2 months because Kirschner wire retracted. Fifteen cases were followed up 8-21 months (mean, 13.5 months). The fracture healing time was from 3 to 6 months (mean, 4.8 months). There was no significant difference in tibial plateau angle and posterior slope angle between at immediate after operation and at last follow-up (t=–1.500, P=0.156; t=–1.781, P=0.097). The anatomic reduction rate of articular surface was 93.8% (15/16) at immediate after operation. At last follow-up, the recollapse height of articular surface was 0.1-1.2 mm (mean, 0.36 mm). According to the HSS score system, the results were excellent in 12 cases, good in 2 cases, and fair in 1 case, and the excellent and good rate was 93.3%. Conclusion The limited incision by posterolateral approach, poking reduction, and simple internal fixation have the advantages of small injury, full exposure, and easy operation in the treatment of simple posterolateral tibial plateau fractures; bone graft support and simple internal fixation can prevent recollapse of the articular surface and achieve satisfactory knee function.
ObjectiveTo investigate the effectiveness of limited open reduction via “door-shaft method” and internal fixation with locking plate for two- and three-part fractures of the proximal humerus.MethodsThe clinical data of 64 patients with proximal humeral fractures who were admitted between January 2013 and December 2016 and met the selection criteria were retrospectively analyzed. There were 23 males and 41 females, with an average age of 68.0 years (range, 50-89 years). The injuries were caused by falling in 57 cases, traffic accident in 5 cases, and falling from height in 2 cases. The interval between injury and operation was 1-7 days (mean, 2.1 days). According to Neer classification, there were 28 cases of two-part fractures and 36 cases of three-part fractures. According to the angulation direction of the proximal humeral neck shaft angle, there were 21 cases of adduction fractures and 43 cases of abduction fractures. The fractures were treated with limited open reduction via “door-shaft method” and proximal humerus internal locking systems for internal fixation. The operation time, intraoperative blood loss, number of fluoroscopy, hospital stay, and complications were recorded. The fracture healing was reviewed by X-ray film and the healing time was recorded. The shoulder joint function was evaluated by Neer score standard.ResultsThe operation time was 45-127 minutes, with an average of 82.3 minutes. The intraoperative blood loss was 30-125 mL, with an average of 62.7 mL. Intraoperative fluoroscopy was performed 30-69 times, with an average of 37.0 times. The hospital stay was 6-23 days, with an average of 10.3 days. All incisions healed by first intention. All patients were followed up 12-37 months, with an average of 18.3 months. X-ray film re-examination showed that all fractures healed, the healing time was 12-21 weeks, with an average of 14.3 weeks. After operation, 3 cases had shoulder stiffness and 1 case had fracture malunion. At last follow-up, the Neer score of shoulder joint function was 49-97, with an average of 83.1. Among them, 38 cases were excellent, 13 cases were good, 10 cases were fair, and 3 cases were poor. The excellent and good rate was 79.7%. The excellent and good rate of patients with two-part fractures was 82.1% (23/28), and the excellent and good rate of patients with three-part fractures was 77.8% (28/36).ConclusionThe “door-shaft method” not only reduces the difficulty of the Joystick technique in the reduction of proximal humerus fractures, but also provides auxiliary stability. It is used for limited open reduction and internal fixation with locking plate to treat the two- and three-part fractures of the proximal humerus, which can achieve good effectiveness.
Objective To investigate the effectiveness of one-stage closed reduction and elastic compression fixation with double Kirschner wires for Wehbe-Schneider types ⅠB and ⅡB bony mallet fingers. Methods Between May 2017 and June 2020, 21 patients with Wehbe-Schneider type ⅠB and ⅡB bony mallet fingers were treated with one-stage closed reduction and elastic compression fixation using double Kirschner wires. There were 15 males and 6 females with an average age of 39.2 years (range, 19-62 years). The causes of injury were sports injury in 9 cases, puncture injury in 7 cases, and sprain in 5 cases. The time from injury to admission was 5-72 hours (mean, 21.0 hours). There were 2 cases of index finger injury, 8 cases of middle finger injury, 9 cases of ring finger injury, and 2 cases of little finger injury. The angle of active dorsiflexion loss of distal interphalangeal joint (DIPJ) was (40.04±4.02)°. According to the Wehbe-Schneider classification standard, there were 10 cases of typeⅠB and 11 cases of type ⅡB. The Kirschner wire was removed at 6 weeks after operation when X-ray film reexamination showed bony union of the avulsion fracture, and the functional exercise of the affected finger was started. Results The operation time was 35-55 minutes (mean, 43.9 minutes). The length of hospital stay was 2-5 days (mean, 3.4 days). No postoperative complications occurred. All patients were followed up 6-12 months (mean, 8.8 months). X-ray films reexamination showed that all avulsion fractures achieved bony union after 4-6 weeks (mean, 5.3 weeks). Kirschner wire was removed at 6 weeks after operation. After Kirschner removal, the visual analogue scale (VAS) score of pain during active flexion of the DIPJ was 1-3 (mean, 1.6); the VAS score of pain was 2-5 (mean, 3.1) when the DIPJ was passively flexed to the maximum range of motion. The angle of active dorsiflexion loss of affected finger was (2.14±2.54)°, showing significant difference when compared with preoperative angle (t=52.186, P<0.001). There was no significant difference in the active flexion angle between the affected finger (79.52±6.31)° and the corresponding healthy finger (81.90±5.36)° (t=1.319, P=0.195). At 6 months after operation, according to Crawford functional evaluation criteria, the effectiveness was rated as excellent in 11 cases, good in 9, and fair in 1, with an excellent and good rate of 95.24%. Conclusion For Wehbe-Schneider typesⅠB and ⅡB bony mallet fingers, one-stage closed reduction and elastic compression fixation with double Kirschner wires can effectively correct the deformity and has the advantages of simple surgery, no incision, and no influence on the appearance of the affected finger.
Objective To compare the effectiveness of ultrasound-guided closed reduction with Kirschner wire fixation and open reduction with Kirschner wire fixation in the treatment of humeral lateral condyle fracture (HLCF) in children. Methods A clinical data of 53 children with HLCF admitted between May 2020 and April 2023 and met selective criteria was retrospectively analyzed. Of these, 25 cases were managed with closed reduction and Kirschner wire fixation under ultrasound guidance (closed group), while 28 cases underwent open reduction and Kirschner wire fixation (open group). There was no significant difference between the two groups in terms of gender, age, cause of injury, fracture side, fracture classification, and time from injury to operation (P>0.05). The following variables were recorded and compared between the two groups: operation time, intraoperative fluoroscopy frequency, fracture healing time, incidence of complications, and the Flynn elbow function score at last follow-up. Results In the closed group, the fractures were successfully reduced under ultrasound guidance, with no nerve damage reported in either group. The operation time and intraoperative fluoroscopy frequency were significantly less in the closed group than in the open group (P<0.05). One case of infection (Kirschner wire irritation) was observed in the closed group, while 3 cases in the open group (2 of Kirschner wire irritation and 1 of incision infection). However, the difference in the incidence of infection between the two groups was not significant (P>0.05). All patients in both groups were followed up 6-18 months (mean, 10.2 months). X-ray examinations confirmed that fractures had healed in both groups, with no significant difference in healing time (P>0.05). During follow-up, 5 cases of lateral humeral process formation were observed in the closed group, compared to 12 cases in the open group, although this difference was not significant (P>0.05). At last follow-up, the excellent and good rate of elbow joint function was evaluated as 96.0% (24/25) in the closed group and 92.9% (26/28) in the open group according to the Flynn scoring criteria, with no significant difference between the two groups (P>0.05). Both groups showed no occurrence of ossifying myositis or elbow internal/external rotation. Conclusion The effectiveness of ultrasound-guided closed reduction and Kirschner wire fixation in the treatment of HLCF in children is comparable to open reduction and Kirschner wire fixation, but the former can reduce operation time and intraoperative fluoroscopy frequency, and obtain lower the incidence of complications.
