  • MODIFIED POSTEROLATERAL COUNTER-CURVED INCISION WITH DOUBLE INTERMUSCULAR APPROACH IN TREATING POSTEROLATERAL TIBIAL PLATEAU FRACTURES

    ObjectiveTo evaluate the effectiveness of the modified posterolateral counter-curved incision with double intermuscular approach for the treatment of posterolateral tibial plateau fractures. MethodsA retrospective analysis was made on the clinical data of 32 patients with posterolateral tibial plateau fractures between September 2012 and October 2014. There were 22 males and 10 females, aged 19 to 55 years (mean, 40.5 years). The causes of injury included traffic accident in 17 cases, falling from height in 9 cases, and falling in 6 cases. They had fresh closed fracture; injury to hospitalization time was 3 hours to 5 days (mean, 2 days). According to Schatzker tibial plateau fracture classification criteria, 20 cases were rated as type II, and 12 cases as type III. All patients underwent a modified posterolateral counter-curved incision with double intermuscular approach to expose tibial posterolateral condyle and anterolateral condyle. After a good visual control of fracture reduction, the anterolateral and posterolateral fractures were fixed with two-dimensional buttress plate respectively. ResultsThe incisions healed at stage I, with no major neurovascular injury. According to radiological assessment of the DeCoster score, the results were excellent in 21 cases, and fair in 11 cases. All of the 32 patients were followed up 18 to 30 months (mean, 20.5 months). The X-ray films showed that all patients obtained good fracture union, and the mean time of fracture union was 12.3 weeks (range, 10-16 weeks). No fixation failure or no obvious loss of articular surface reduction was observed during follow-up. The range of motion of the affected knees was 2-135° (mean, 120°). The mean American Hospital for Special Surgery (HSS) score was 90.05 (range, 83-96) at 18 months after operation. ConclusionThe modified posterolateral counter-curved incision with double intermuscular approach could fully expose posterolateral tibia plateau, and good fracture reduction and reliable fixation can be obtained under direct vision.

  • TREATMENT OF POSTEROLATERAL TIBIAL PLATEAU COLLAPSED AND SPLITED FR ACTURES BY POSTEROMEDIAL AND ANTEROL ATER AL APPROACHES

    ObjectiveTo explore the effectiveness of posteromedial and anterolateral approaches in the treatment of posterolateral tibial plateau collapsed and splited fractures. MethodsNineteen consecutive patients with posterolateral tibial plateau collapsed and splited fractures were treated between August 2010 and August 2013, and the clinical data were retrospectively analyzed. There were 13 males and 6 females, with an average age of 36.9 years (range, 25-75 years). All cases had closed fractures, involving 8 left sides and 11 right sides. Fractures involved posterior column according to the threecolumn classification based on CT scans; according to the Schatzker classification, all fractures were type Ⅱ; according to the AO/Association for the Study of Internal Fixation classification (AO/OTA), all fractures were type 41-B3.1.2. The interval between injury and operation was 7-14 days (mean, 9 days). The reduction of collapsed fractures and implantation of artificial bone allograft were supported by T-shaped distal radius plate via the posteromedial approach. The splited fractures was fixed by less invasive stabilization system (LISS) plate via the anterolateral approach. ResultsThe mean operation time was 69.0 minutes (range, 50-105 minutes). All incisions healed by first intention without neurovascular complications or wound infection. All patients were followed up 14-20 months (mean, 18.2 months). X-ray and CT examinations showed that collapsed tibial plateau and joint surface were completely corrected; bony union was obtained at 12 weeks on average (range, 10-16 weeks). No secondary collapsed fracture and knee varus or valgus occurred. The results were excellent in 12 cases, good in 5 cases, and fair in 2 cases with an excellent and good rate of 89.5% according to the Rasmussen's scoring system for knee function. ConclusionThe posteromedial approach combined with anterolateral approach for posterolateral tibial plateau fractures can fully expose the posterolateral aspects of the tibial plateau, and thus collapsed and splited fractures can be treated at the same time, which will lead to less operative time and good outcomes in the treatment of posterolateral tibial plateau collapsed and splited fractures.

  • Application of elbow arthrography through lateral approach in treatment of elbow fractures in infants

    ObjectiveTo evaluate the effectiveness of elbow arthrography through lateral approach in the treatment of elbow fractures in infants.MethodsThe clinical data of 24 infants with elbow fractures admitted between May 2016 and May 2018 were retrospectively analyzed. There were 14 boys and 10 girls with an average age of 1.8 years (range, 2 months to 3 years). The time from injury to admission ranged from 1 hour to 7 days, with an average of 6.7 hours. The preoperative carrying angle was (30.8±4.5)° (range, 24°-41°), and the elbow range of motion was (128.5±4.5)° (range, 125°-134°). Elbow arthrography through lateral approach was used in all cases, including 10 cases of humeral lateral condylar fracture, 6 cases of distal humeral epiphysis fracture, 3 cases of fresh Monteggia fracture, and 5 cases of radial neck fracture. According to fracture types, open reduction with Kirschner wire fixation, closed reduction with plaster cast fixation, or closed reduction with percutaneous Kirschner wire fixation were used.ResultsNone of the children had adverse reactions such as drug allergy. All patients were follow-up 14-38 months, with an average of 19.6 months. The skin irritation around the needle tail occurred in 2 cases after operation, and the symptoms disappeared after the Kirschner wire was pulled out. The anteroposterior and lateral X-ray films of elbow joint showed that the fractures healed well and no mulunion at the fracture site or premature epiphysis closure was observed. At last follow-up, the carrying angle was (5.2±1.9)° (range, 2°-8°) and the elbow range of motion was (137.1±4.7)° (range, 133°-141°), which were significantly improved when compared with those before operation (t=22.670, P=0.000; t=11.910, P=0.000). According to Flynn clinical function evaluation standard of elbow joint, 22 cases were excellent, 1 case was good, and 1 case was fair. The excellent and good rate was 95.8%.ConclusionElbow arthrography through lateral approach can clearly judge the cartilage damage of the elbow joint surface in infants, and minimize the occurrence of misdiagnosis and missed diagnosis, and can guide the choice of treatment.

  • NEW ANTEROLATERAL APPROACH OF DISTAL FEMUR FOR TREATMENT OF TYPE C DISTAL FEMORAL FRACTURES

    ObjectiveTo study the effectiveness of a new anterolateral approach of distal femur in the treatment of type C distal femoral fractures by comparing with traditional lateral and anterolateral approaches. MethodsThe clinical data of 51 patients with type C distal femoral fractures treated between January 2008 and August 2011 were retrospectively analyzed. Of 51 patients, 24 patients received the new anterolateral approach of distal femur combined with fixation of condylar buttress plate (modified group), and 27 patients underwent traditional lateral or anterolateral approach combined with fixation of condylar buttress plate (traditional group). There was no significant difference in gender, age, injury cause, American Society of Anesthesiologist (ASA) classification, side, fracture type, complication, and the time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, hospitalization time, fracture healing time, and Hospital for Special Surgery (HSS) scores of the knee at 3, 6, and 12 months were recorded. ResultsThe operation was successfully completed and the incision healed by first intention in all patients. The operation time and frequency of intraoperative fluoroscopy of modified group were significantly less than those of traditional group (P<0.05). But the intraoperative blood loss and the hospitalization time showed no significant difference between 2 groups (P>0.05). All patients were followed up 12-37 months (mean, 21.3 months). X-ray films showed all fractures were union. The fracture healing time was (12.92±2.24) weeks in the modified group and (13.24±2.52) weeks in the traditional group, showing no significant difference (t=0.476, P=0.637). The knee HSS scores of modified group were significantly higher than those of traditional group at 3, 6, and 12 months after operation (P<0.05). There was no significant difference in the incidence of knee varus or valgus, leg length discrepancy, internal fixator loosening, flexing dysfunction of knee, traumatic arthritis of knee, and total complications between 2 groups (P>0.05). ConclusionComparing with traditional lateral and anterolateral approaches, using the new anterolateral approach to treat type C distal femoral fractures has the advantages of less damage to soft tissue, excellent exposure, less operation time, and frequency of intraoperative fluoroscopy, and better postoperative rehabilitation of knee joint.

  • Comparison of effectiveness between plate and screw internal fixation in treatment of posterior malleolus fractures through posterolateral approach

    ObjectiveTo compare the effectiveness of posterior malleolus fractures treated by plate and screw internal fixation through posterolateral approach.MethodsThe clinical data of 95 patients with posterior malleolus fractures who were admitted between January 2016 and December 2019 and met the selection criteria were retrospectively analysed. They were divided into plate group (44 cases, treated with posterolateral plate internal fixation) and screw group (51 cases, treated with posterolateral screw internal fixation) according to different treatment methods. There was no significant difference in general data between the two groups of patients such as age, gender, cause of injury, side of injury, ankle fracture or injury classification, time from injury to operation, and percentage of posterior ankle fracture area to the distal tibia articular surface (P>0.05). The operation time, hospital stay, fracture healing time, and surgical complications were compared between the two groups. Imaging examinations (X-ray film, CT scan and reconstruction) were used to assess the reduction quality of ankle fracture, articular congruity, and re-displacement in ankle fracture. At last follow-up, the pain visual analogue scale (VAS) score was used to evaluate the patients’ pain, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used to evaluate ankle joint function.ResultsPatients in both groups were followed up 6-30 months, with an average of 18.2 months. The operation time of the plate group was significantly longer than that of the screw group (U=−2.040, P=0.041); there was no significant difference in hospital stay between the two groups (U=−1.068, P=0.285). Incision swelling occurred in 2 cases in the plate group, sural nerve injury in 3 cases, and traumatic arthritis in 2 cases during follow-up. In the screw group, there were 1, 2, and 2 cases, respectively. The incidence of complications in the two groups (15.9% vs. 9.8%) was not significantly different (P=0.372). All patients who underwent tibiofibular screw fixation underwent the removal of the tibiofibular screw before taking full weight bearing at 12 weeks after operation, and there was no screw fracture and retention. During the follow-up, there was no infection, re-displacement of fracture, delayed bone union or nonunion, and there was no significant difference in fracture healing time between the two groups (t=0.345, P=0.731). There was no significant difference between the two groups of reduction quality of ankle fracture and articular congruity evaluation results (P>0.05). At last follow-up, there was no significant difference in VAS score, AOFAS ankle-hindfoot score and evaluation grade between the two groups (P>0.05).ConclusionBoth the plate and screw internal fixation through posterolateral approach can achieve satisfied effectiveness in the treatment of posterior ankle fractures with maintenance of fracture reduction, and recovery of ankle joint function. The screw internal fixation has the advantages of minimal invasion and shorter operation time.

  • Randomized controlled trial of comparison between the SuperPATH and posterolateral approaches in total hip arthroplasty

    Objective To evaluate the effectiveness of SuperPATH approach in total hip arthroplasty (THA) compared with conventional posterolateral approach. Methods Between March 2017 and May 2017, 24 patients who planned to have a unilateral THA were enrolled in the study and randomized into 2 groups. Twelve patients were treated with SuperPATH approach (SuperPATH group) and 12 patients with posterolateral approach (control group). There was no significant difference in gender, age, body mass index, the type of disease, complicating diseases, and American Society of Anesthesiologists grading between 2 groups (P>0.05). The operation time, length of stay, length of incision, and perioperative complications related to operation were recorded. The hemoglobin and hematocrit were recorded; the total blood loss and intraoperative blood loss were calculated. The inflammatory response indicators (C-reactive protein, erythrocyte sedimentation rate) and muscle damage index (creatine kinase) were recorded in both groups. The range of motion, functional score (Harris score), visual analogue scale (VAS) score, and prosthesis position were recorded. Results Patients in both groups were followed up 1 year. Compared with the control group, the operation time of the SuperPATH group was longer (t=4.470, P=0.000), and the incision was shorter (t=–2.168, P=0.041). There was no significant difference in length of stay between 2 groups (t=0.474, P=0.640). Periprosthetic fracture occurred in 1 case of the SuperPATH group. No other complications, such as infection or deep vein thrombosis, occurred in both groups. There was no significant difference in intraoperative blood loss, total blood loss, hemoglobin and hematocrit before operation and at 1 and 3 days after operation, and C-reactive protein and erythrocyte sedimentation rate before operation and at 1, 3, and 14 days between 2 groups (P>0.05). For creatine kinase, SuperPATH group at 1 and 3 days were lower than control group (P<0.05), while no significant difference was found between 2 groups before operation and at 14 days after operation (P>0.05). For flexion and abduction activity, SuperPATH group at 1 and 3 days after operation were better than the control group (P<0.05), while no significant difference was found between 2 groups at 14 days, 3 months, 6 months, and 1 year after operation (P>0.05). The Harris and VAS scores of SuperPATH group at 1 and 3 days after operation were better than those of control group (P<0.05). There was no significant difference in anteversion and abduction between 2 groups (P>0.05) according to the X-ray film at 1 year. During the follow-up, no loosening or migration was observed. Conclusion Compared with the posterolateral approach, the SuperPATH approach can reduce muscle damage, relieve early pain, promote recovery, and obtain the similar short-term effectiveness.

  • A prospective study of vertebroplasty with reverse designed unilateral targeted puncture for osteoporotic thoracolumbar compression fractures

    Objective To explore the feasibility and effectiveness of vertebroplasty with reverse designed unilateral targeted puncture in treatment of osteoporotic vertebral compression fracture (OVCF) by comparing with curved unilateral puncture. Methods A total of 52 patients with OVCF met selection criteria and were admitted between January 2019 and June 2021 were selected as the research objects. According to the random number table method, they were divided into two groups (n=26). In trial group, the reverse designed unilateral targeted puncture was used in the percutaneous vertebroplasty (PVP); while the control group used the curved unilateral puncture. There was no significant difference in gender, age, bone mineral density (T value), cause of injury, time from injury to operation, the level of responsible vertebral body, pedicle diameter of the planned puncture vertebral body, and preoperative visual analogue scale (VAS) score, anterior vertebral height, and Cobb angle between the two groups (P>0.05). The operation time, bone cement injection volume and leakage, intraoperative radiation exposure times, and hospitalization costs in the two groups were recorded. VAS score was used to evaluate the relief degree of low back pain after operation. X-ray film was used to review the diffusion degree of bone cement in the responsible vertebral body, and Cobb angle and anterior vertebral height were measured. Results The operation was successfully completed in the two groups. Patients in the two groups were followed up 12-18 months, with an average of 13.6 months. The operation time, volume of injected bone cement, intraoperative radiation exposure times, and hospitalization costs in the trial group were significantly lower than those in the control group (P<0.05). With the prolongation of time, the low back pain of the two groups gradually relieved, and the VAS score significantly decreased (P<0.05). And there was no significant difference in VAS score between the two groups at each time point (P>0.05). There were 2 cases (7.6%) of bone cement leakage in the trial group and 3 cases (11.5%) in the control group, and no significant difference was found in the incidence of bone cement leakage and the diffusion degree of bone cement between the two groups (P>0.05). Imaging examination showed that compared with pre-operation, the anterior vertebral height of the two groups significantly increased and Cobb angle significantly decreased at 2 days and 1 year after operation (P<0.05); while compared with 2 days before operation, the anterior vertebral height of the two groups significantly decreased and Cobb angle significantly increased at 1 year after operation (P<0.05). There was no significant difference in the above indexes between the two groups at different time points after operation (P>0.05). Conclusion Compared with curved unilateral puncture, the use of reverse designed unilateral targeted puncture during PVP in the treatment of OVCF can not only achieve similar effectiveness, but also has the advantages of less radiation exposure, shorter operation time, and less hospitalization costs.

  • Short-term effectiveness analysis of one-stage bilateral total hip arthroplasty by direct anterior approach

    Objective To compare the effectiveness of one-stage bilateral total hip arthroplasty by direct anterior approach (DAA) and by posterolateral approach, and to investigate the application value of DAA in one-stage bilateral total hip arthroplasty. Methods The clinical data of 65 patients who underwent one-stage bilateral total hip arthroplasty by DAA or posterolateral approach between June 2010 and November 2015 were analyzed retrospectively. DAA was used in 34 cases (group A) and posterolateral approach was used in 31 cases (group B). There was no significant difference in the gender, age, body mass index, preoperative hemoglobin level, etiology, disease duration, preoperative Harris score, and preoperative visual analogue scale (VAS) score between 2 groups (P>0.05) with comparability. The incision length, operation time, intraoperative blood loss, total blood transfusion volume, hospitalization time, early postoperative complications, Harris score, and VAS score were recorded and compared between 2 groups. The simple Likert scale method was applied to evaluate the patient satisfaction, and the imaging evaluation was used. Results The incision length, operation time, intraoperative blood loss, total blood transfusion volume, and hospitalization time of group A were significantly less than those of group B (P<0.05). The patients were followed up 15-48 months (mean, 25.3 months) in group A and 12-51 months (mean, 27.6 months) in group B. The overall incidence of complications related to surgery in group A (10.29%) was significantly lower than that of group B (19.35%) (χ2=8.769, P=0.023). The acetabular anteversion and abduction angle were in the normal range of 2 groups except 1 hip (1.47%) of group A had a higher acetabular anteversion than normal value. Unstable fixed prosthesis happened in 1 hip of groups A and B respectively, and the remaining femoral calcar had no obvious bone resorption and fixed stably. The Harris score and VAS score at each time point after operation of 2 groups were significantly improved when compared with preoperative scores (P<0.05), and the differences between the time points after operation were also significant (P<0.05). The Harris score at 1 and 3 months after operation and the VAS score at 3 days after operation of group A were significantly better than those of group B (P<0.05), but no significant difference was found at last follow-up between 2 groups (P>0.05). According to the simple Likert scale method to analyze patient satisfaction, comprehensive satisfaction of group A (97.1%, 33/34) was significantly higher than that of group B (67.7%, 21/31) (χ2=10.343, P=0.001). Conclusion The application of DAA in one-stage bilateral total hip arthroplasty can significantly relieve the pain, accelerate the recovery of hip joint function, and improve the patient satisfaction. But in clinical application, more attentions should be paid to strictly grasp the indications and prevent the early complications. The long-term effectiveness needs to be further observed.

    Objective To evaluate the effect of anterolateral approach in treating thoracolumbar disc protrusion. Methods From May 2004 to May 2008, 11 patients with thoracolumbar disc protrusion (T10-L3) underwent discectomy, autologous il iac bone graft, and internal fixation via anterolateral approach. There were 9 males and 2 females aged 26-57 years old (average 42.8 years old). The course of disease was 1 week-11 years (average 2.7 years). Nine patients showed the lower l imbs weakness, 8 had sensory disturbance, 6 presented with lumbodorsal pain, 5 had the lower l imb pain, 4 presentedwith sphincter muscle disturbance, 3 suffered from foot drop, and 5 had a history of lower back injury. X-ray, CT, and MRI test showed that 9 cases had the single-segmental protrusion, 2 cases had double-segmental protrusion, 2 cases were accompanied with ossification of the thoracic vertebra yellow l igament, 2 cases were combined with ossification of the vertebra posterior longitudinal l igament, and 1 was compl icated with Scheuermann disease. Preoperatively, the intervertebral height was (7.2 ± 1.3) mm and JOA score was 6.4 ± 2.8. Results The time of operation was 2.5-5.5 hours (average 3.5 hours); the blood loss during operation was 500-1 200 mL (average 750 mL). During operation, intraoperative pleural tear occurred in 1 patient, peritoneal tear in 1 patient, and dural laceration in 1 patient. Repairing was performed intraoperative and preventive suction drainage was used for 3-5 days. No postoperative hydropneumothorax and cerebrospinal fluid leakage occurred. All incisions healed by first intention. No postoperative compl ications of nerve system occurred. All the patients were followed up for 1-4 years (average 2.4 years). X-ray films showed that all the patients achieved bony fusion without the occurrence breakage and loosening of titanium plate and screw 6-9 months after operation. Three cases displayed subtle scol iosis (10-15°) without influence on spinal equil ibration. The intervertebral height increased to (12.3 ± 1.5) mm 2 weeks after operation, indicating there was a significant difference compared with preoperative value (P lt; 0.05). The intervertebral height 1 year after operation when the bony fusion was reached decreased to (7.5 ± 1.2) mm, indicating there was no significant difference compared to the preoperative value (P gt; 0.05). The JOA score increased to 7.6 ± 3.2 at 1 year after operation, indicating there was a significant difference compared with preoperative value (P lt; 0.05). The symptoms and signs of all the patients were improved to various degrees after operation. According to improvement rate evaluation system proposed by Hirabayashi t al., 4 cases were graded as excellent, 6 as good, 1 as fair, and the excellent and good rate was 90.9%. Conclusion Treating thoracolumbar disc protrusion via anterolateral approach is safe and effective.
