Objective To compare the effectiveness and advantages of the double reverse traction reduction versus open reduction internal fixation for treating complex tibial plateau fractures. Methods A clinical data of 25 patients with Schatzker type Ⅴ or Ⅵ tibial plateau fractures, who met the selection criteria and were admitted between January 2019 and January 2023, was retrospectively analyzed. Thirteen patients underwent double reverse traction reduction and internal fixation (double reverse traction group), while 12 patients underwent open reduction and internal fixation (traditional open group). There was no significant difference in the baseline data (age, gender, injury mechanism, Schatzker classification, interval between injury and operation) between the two groups (P>0.05). The effectiveness were evaluated and compared between the two groups, included operation time, intraoperative blood loss, incision length, hospital stay, full weight-bearing time, complications, fracture healing, Rasmussen radiological score (reduction quality), knee Hospital for Special Surgery (HSS) score, and knee flexion/extension range of motion. Results The double reverse traction group demonstrated significantly superior outcomes in operation time, intraoperative blood loss, hospital stay, incision length, and time to full weight-bearing (P<0.05). Two patients in traditional open group developed incisional complications, while the double reverse traction group had no complication. There was no significant difference in the incidence of complication between the two groups (P>0.05). All patients were followed up 24-36 months (mean, 30 months), with no significant difference in follow-up duration between groups (P>0.05). Fractures healed in both groups with no significant difference in healing time (P>0.05). At 6 months after operation, Rasmussen radiological scores and grading showed no significant difference between the two groups (P>0.05); the double reverse traction group had significantly higher HSS scores compared to the traditional open group (P<0.05). At 12 months after operation, knee flexion/extension range of motion were significantly greater in the double reverse traction group than in the traditional open group (P<0.05). ConclusionDouble reverse traction reduction offers advantages over traditional open reduction, including shorter operation time, reduced blood loss, minimized soft tissue trauma, and improved joint functional recovery. It is a safe and reliable method for complex tibial plateau fractures.
ObjectiveTo investigate the effectiveness of closed or limited open reduction and intramedullary nail fixation in the treatment of Seinsheimer type Ⅴ subtrochanteric fracture.MethodsBetween May 2014 and July 2018, 36 patients with Scinsheimer type Ⅴ subtrochanteric fractures were treated with closed or limited open reduction and intramedullary nail fixation. There were 25 males and 11 females with an age of 23-86 years (mean, 55.8 years). The cause of injury included falling in 19 cases, traffic accident in 9 cases, falling from height in 7 cases, and heavy object injury in 1 case; all were fresh closed injuries. The interval between injury and operation was 1-14 days (mean, 6.8 days). There were 18 cases of closed reduction and 18 cases of limited open reduction during the operation. Seventeen cases were fixed with femoral reconstruction intramedullary nail, 5 with InterTan long nail, 14 with lengthened proximal femoral nail anti-rotation, and 7 cases were assisted with auxiliary steel wire binding. After operation, through X-ray film and clinical follow-up, the fracture reduction and maintenance status, internal fixation position, and fracture healing were judged; the range of motion, walking ability, and complications of hip joint were observed, and the function of hip joint was evaluated according to Merle d’Aubigne Postel hip joint scoring standard.ResultsAll the incisions of medullary operation healed by first intention, and no vascular, nerve injury, or infection occurred. All patients were followed up 12-24 months, with an average of 14.2 months. Among the 36 patients, 1 patient received revision surgery due to varus displacement of femoral head and screw penetration at 2 months after closed reduction, with poor recovery of hip function. X-ray film re-examination showed that the fractures of the other 35 patients healed after 9-15 months, with an average of 11.5 months. During follow-up, there was no complication such as internal fixation failure, fracture redisplacement, bone nonunion or malunion, and deep vein thrombosis of lower extremity occurred. The function of hip joint recovered well, and the patients could walk and squat normally without affecting daily life or work. At last follow-up, according to Merle d’Aubigne Postel hip joint scoring standard, 28 cases were rated as excellent, 4 cases as good, 3 cases as fair, and 1 case as poor, the excellent and good rate was 88.9%.ConclusionC-arm X-ray fluoroscopic closed or limited open reduction and intramedullary nail fixation for the treatment of Seinheimer Ⅴ type subtrochanteric fracture, if necessary, with the aid of auxiliary steel wire binding, it has the advantages of less blood supply destruction at the fracture end, satisfactory reduction, firm fixation, and early rehabilitation training, with definite effectiveness.
Objective To compare the effectiveness of early versus delayed closed reduction and percutaneous Kirschner wire fixation in the treatment of pediatric supracondylar humerus fractures. Methods A retrospective analysis was conducted on 468 children with supracondylar humerus fractures, who were admitted between January 2020 and December 2023 and met the inclusion criteria. Among them, 187 children were treated during 12 hours after injury (early operation group) and 281 were treated after 12 hours (delayed operation group). There was no significant difference between the two groups (P>0.05) in the gender, age, injury mechanism, fracture side and type, while there was significant difference in interval from injury to operation (P<0.05). The operative outcomes, including the operation time, intraoperative blood loss, the length of hospital stay, fracture healing time, elbow function assessed by Flynn criteria at 3 months after operation, and complications, were compared. Results Compared to the delayed operation group, the early operation group demonstrated significantly shorter operation time and less intraoperative blood loss (P<0.05). There was no significant difference in the length of hospital stay between the two groups (P>0.05). All children were followed up 3-12 months. The follow-up time was (6.7±2.9) months in the early operation group and (6.9±2.8) months in the delayed operation group, showing no significant difference between the two groups (P>0.05). There was no significant difference in the fracture healing time between the two groups (P>0.05). At 3 months after operation, the early operation group exhibited superior Flynn elbow functional outcomes to the delayed operation group (P<0.05). In the early operation group, there was 1 case of fracture non-union and 3 cases of cubital varus deformity after operation. In the delayed operation group, there was 1 case of nerve injury, 7 cases of fracture non-union, and 12 cases of cubital varus deformity after operation. There was significant difference in the incidence of complications between the two groups (P<0.05). One case of the early operation group and 10 cases of the delayed operation group underwent secondary operation, showing no significant difference in the incidence of secondary operation between the two groups (P>0.05). ConclusionFor pediatric supracondylar humerus fractures, early closed reduction and percutaneous Kirschner wire fixation can reduce operation time, minimize intraoperative blood loss and postoperative complications, and improve the functional recovery compared to delayed operation.
Objective To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. Methods The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups (P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury incidence, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. Results The closed reduction rate of the study group was significantly higher than that of the control group (P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] (χ2=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group (P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the incidence of ulnar nerve injury between the two groups (P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group (P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups (P>0.05). Conclusion In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.
ObjectiveTo explore the efficacy and advantages of the lower extremity axial distractor assisted closed reduction and retrograde intramedullary nail internal fixation in the treatment of distal femoral fractures.MethodsThe clinical data of 49 patients with distal femoral fractures treated with retrograde intramedullary nail internal fixation between April 2016 and December 2018 were retrospectively analyzed. According to the different methods of intraoperative reduction, the patients were divided into trial group (29 cases, using lower extremity axial distractor to assist closed reduction) and control group (20 cases, using free-hand retraction reduction). There was no significant difference in general information between the two groups (P>0.05), such as gender, age, side of injury, cause of injury, and fracture classification. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, and callus formation time were recorded and compared between the two groups. The function of the affected limb was evaluated according to the Schatzker-Lambert standard at 1 year after operation.ResultsAll patients successfully completed the operation. In the control group, there was 1 case with open reduction and internal fixation, and the rest of the two groups were closed reduction. There was no significant difference in operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency between the two groups (P>0.05). There was no complication such as vascular or nerve injury and iatrogenic fracture, etc. during and after operation, and the incisions healed by first intention. Except for 2 patients in the trial group who were lost to follow-up at 3 months after operation, the rest of the patients were followed up 12-36 months, with an average of 16.0 months. There was no significant difference in the callus formation time between the two groups (t=2.195, P=0.145). During the follow-up, postoperative knee joint stiffness occurred in 1 case in the control group, which improved by strengthening the knee joint function exercise and removing the internal fixator; the rest were not found to be associated with delayed or nonunion fractures, knee stiffness, and internal fixation complication. The function of the affected limb was evaluated according to the Schatzker-Lambert standard at 1 year after operation, the trial group achieved excellent results in 22 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 96.3%; in the control group, the results were excellent in 16 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate was 95.0%; showing no significant difference in the excellent and good rate between the two groups (χ2=0.451, P=0.502).ConclusionThe lower extremity axial distractor assisted closed reduction and retrograde intramedullary nailing for the treatment of distal femoral fractures is convenient, which has satisfactory efficacy.
Objective To evaluate the results of arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, IIB, and IIIAB. Methods Sixteen patients with unilateral calcaneal fracture were treated with arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint between June 2012 and June 2015. There were 13 males and 3 females with an average age of 37.8 years (range, 18-65 years). The injury causes included falling from height in 10 cases and traffic accident in 6 cases. Of 16 cases, 4 were classified as Essex-Lopresti tongue type, 5 as Sanders IIA, 4 as Sanders IIB, and 3 as Sanders IIIAB. The interval of injury and operation was 4-8 days (mean, 5.94 days). The Böhler angle, Gissane angle, and width of calcaneus were measured before and after operation. American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate the ankle function at 12 months after operation. Results Primary healing of incision was obtained in all cases, and no complications of infection, necrosis, and osseous fascia compartment syndrome occurred. The patients were followed up 12-15 months (mean, 13.63 months). The X-ray films showed that fracture line disappeared at 6 months after operation; the patients had no tenderness or percussion pain, no breakage or loosening of internal fixation, no varus calcaneus tuberosity, no subtalar joint fusion, and no compression symptoms of peroneal tendons. Achilles tendon irritation occurred in 2 cases, and disappeared after removal of internal fixation; traumatic arthritis occurred in 2 cases, and was relieved after removal of internal fixation. The Böhler angle, Gissane angle, and calcaneal width were significantly improved at 3 days and 6 months after operation when compared with preoperative ones (P<0.05). The loss of the above indexes was observed at 6 months, showing no significant difference between at 3 days and 6 months (P>0.05). The AOFAS score results were excellent in 11 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 87.5%. Conclusion It has the advantages of little trauma, less complication, and good function recovery to use arthroscopically-assited closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, Sanders IIB, and Sanders IIIAB.
ObjectiveTo evaluate the feasibility and effectiveness of percutaneous screwdriver rod-assisted closed reduction in the treatment of valgus-impacted femoral neck fractures. MethodsBetween January 2021 and May 2022, 12 patients with the valgus-impacted femoral neck fractures were treated with percutaneous screwdriver rod-assisted closed reduction and femoral neck system (FNS) internal fixation. There were 6 males and 6 females with a median age of 52.5 years (range, 21-63 years). The fractures were caused by traffic accident in 2 cases, falling in 9 cases, and falling from height place in 1 case. All were unilateral closed femoral neck fractures, including 7 on the left side and 5 on the right side. The time from injury to operation was 1-11 days, with an average of 5.5 days. The fracture healing time and postoperative complications were recorded. The quality of fracture reduction was evaluated by Garden index. At last follow-up, Harris score was used to evaluate the hip joint function, also the shortening of femoral neck was measured. ResultsAll the operations were successfully completed. After operation, the incision fat liquefaction occurred in 1 case, which healed after enhanced dressing change, and the other patients’ incisions healed by first intention. All patients were followed up 6-18 months, with an average of 11.7 months. The X-ray film reexamination showed that the quality of fracture reduction was grade Ⅰ in 10 cases and grade Ⅱ in 2 cases according to the Garden index. All fractures reached bony union, and the healing time was 3-6 months, with an average of 4.8 months. At last follow-up, the femoral neck was shortened by 1-4 mm, with an average of 2.1 mm. No internal fixation failure or osteonecrosis of the femoral head occurred during follow-up. At last follow-up, the hip Harris score was 85-96, with an average of 92.4; 10 cases were rated as excellent and 2 were good. Conclusion The percutaneous screwdriver rod-assisted closed reduction can effectively reduce the valgus-impacted femoral neck fracture. It has the advantages of simple operation, effective, and less impact on blood supply.
ObjectiveTo investigate the effectiveness of closed reduction and internal fixation with elastic nails in treatment of Mason type Ⅱ radial head fracture in adults.MethodsA clinical data of 28 patients with Mason type Ⅱ radial head fractures between May 2013 and March 2017 was retrospectively analyzed. Thirteen patients were treated with closed reduction and internal fixation with elastic nails (trial group); 15 patients were treated with open reduction and internal fixation with Herbert screws (control group). There was no significant difference in gender, age, cause of injury, side of fracture, and the time from injury to operation between the two groups (P>0.05). The operation time, blood loss, and fluoroscopy times in the two groups were recorded and compared. Postoperative X-ray films were used to evaluate the bone healing, heterotopic ossification, and necrosis of radial head. The effectiveness was evaluated according to Mayo score criteria of the elbow at last follow-up. ResultsAll patients were followed up 12-30 months (mean, 21.9 months). The operation time and blood loss were significantly less in the trial group than in the control group (P<0.05), while the fluoroscopy times significantly increased in the trial group than in the control group (P<0.05). X-ray films showed that all fractures healed with the bone healing time of (2.85±0.69) months in the trial group and (3.35±0.88) months in the control group. There was no significant difference in bone healing time between the two groups (t=1.654, P=0.110). Heterotopic ossification occurred in 2 cases in the control group. At last follow-up, there was no significant difference in the Mayo scores between the trial group (90.6±5.3) and the control group (86.4±7.1) (t=1.750, P=0.092).ConclusionClosed reduction and internal fixation with elastic nails, as a minimally invasive technique, has advantages of short operation time and less bleeding in the treatment of Mason type Ⅱ radial head fracture.
Objective To determine the effectiveness and the safety of the Taylor spatial frame in treatment of intermediate or distal tibiofibula fractures. Methods The clinical data of 74 patients with intermediate or distal tibiofibular fractures treated between January 2015 and January 2017 were retrospectively analyzed. According to fixation methods, they were divided into internal fixation group (26 cases) and external fixation group (48 cases). There was no significant difference in the age, gender, cause of injury, type of fracture, time from injury to operation between 2 groups (P>0.05). The intraoperative blood loss, fracture healing time, fixator removal time, and complications were recorded and compared. The final function evaluation criteria of Johner-Wruhs humeral shaft fracture were used to evaluate the function of the affected limb. The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfenget al. Results Both groups were followed up 6-22 months (median, 14 months). All patients obtained the fracture healing. The intraoperative blood loss, fracture healing time, and fixator removal time were significantly higher in the internal fixation group than those in the external fixation group (P<0.05). There were 1 case of plate exposure, 1 case of delayed fracture healing, and 1 case of plate fracture in the internal fixation group; and there were 2 cases of delayed fracture healing and 4 cases of soft tissue defect in the external fixation group; no significant difference was found in the incidence of complications between 2 groups (χ2=0.015, P=0.904). The function of the affected limb was evaluated by Johner-Wruhs standard at 10 months after operation, the results was excellent in 19 cases, good in 5 cases, and fair in 2 cases in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 42 cases, good in 3 cases, and fair in 2 cases in the external fixation group, with an excellent and good rate of 95.7%; showing no significant difference between 2 groups (χ2=0.392, P=0.531). The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfeng et al.at 4 months after operation, the results was excellent in 24 cases, fair in 1 case, poor in 1 case in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 46 cases, fair in 1 case, poor in 1 case in the external fixation group, with an excellent and good rate of 95.8%; showing no significant difference between 2 groups (χ2=0.520, P=0.471). Conclusion The use of Taylor spatial frame in the treatment of the intermediate or distal tibiofibular fractures can obviously reduce the healing time and complications than the internal fixation of the plate. It can reduce the fracture treatment cycle and is beneficial to the fracture healing and limb function recovery, which is relatively safe and reliable.
Objective To compare the effectiveness of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet fingers. Methods The clinical data of 68 patients with bony mallet finger who admitted between May 2019 and June 2022 were retrospectively analyzed. Among them, 33 cases were in the open group (treated with open reduction and hook plate fixation) and 35 cases were in the closed group (treated with closed indirect reduction and dorsal extension blocking Kirschner wire fixation). There was no significant difference between the two groups in terms of gender, age, the affected side, the affected finger, cause of injury, time from injury to operation, and Wehbé-Schneider classification (P>0.05). The operation time, intraoperative fluoroscopy frequency, fracture healing time, time of returning to work, and postoperative complications were recorded and compared between the two groups. At 12 months after operation, visual analogue scale (VAS) score was used to assess the pain of the injured finger, active flexion range of motion and extension deficit of the distal interphalangeal joint (DIP) were measured by goniometer, and the effectiveness was assessed by Crawford criteria. Results All patients in the two groups were followed up 12-26 months, with an average of 15 months. There was no significant difference in the follow-up time between the closed group and the open group (P>0.05). The operation time in the closed group was shorter than that in the open group, and the intraoperative fluoroscopy times, the fracture healing time, and the time of returning to work in the closed group were more than those in the open group, and the differences were significant (P<0.05). In the closed group, there were 5 cases of pinning tract infection and 3 cases of small area pressure ulcer skin necrosis on the dorsal side of the finger, which were cured after intensive nursing and dressing change. Local nail depression deformity occurred in 7 cases in the open group, and the deformity disappeared after removal of plate. The incisions of the other patients healed uneventfully without complications such as infection, skin necrosis, exposure of the internal fixation, or nail deformity. There was no significant difference in the incidence of skin necrosis between the two groups (P>0.05), but the differences in the incidence of infection and nail deformity between the two groups were significant (P<0.05). There was no significant difference in VAS score, DIP active flexion range of motion, DIP extension deficiency, or Crawford criteria evaluation between the two groups at 12 months after operation (P>0.05). At last follow-up, there was no DIP osteoarthritis and joint degeneration in both groups. Conclusion Open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation have their own advantages and disadvantages, but both of them have good results in the treatment of bony mallet fingers. Open reduction and hook plate fixation is recommended for young patients with bony mallet fingers who are eager to return to work.
