ABSTRACT
SUMMARY: For the treatment of trigeminal neuralgia, the foramen ovale is reached by entering the cheek with a needle. Thermocoagulation is performed with balloon compression, administration of alcohol or radiofrequency. Apart from the classical method, it is theoretically possible to reach the foramen ovale through the mouth with the anterior approach. In our study, it was aimed to examine horizontally and vertically the angular values that must be given to the needle to reach the foramen ovale in the anterior approach. Three landmark points were determined on both right and left sides of 25 dry skulls. A rod was inserted starting from these landmark points and passing through the center of the foramen ovale. The vertical and horizontal angular values of this bar were measured. For each foramen ovale, 3 vertical angles, 3 horizontal angles and 4 distance measurements were made. There was a significant difference between the right and left sides in terms of horizontal angular values. Average values of horizontal angles (in degrees); on the right, 7.29 for H1, 12.15 for H2, 32.29 for H3; 1.26 for H1, 9.46 for H2, and 30.56 for H3 on the left side (p<0.005). The angle value was measured as 0 or negative value in 5 (20 %) of the H1 angle measurements made on the right side and 14 (56 %) on the left side. The H2 angle value was found to be smaller than the H1 angle in the skull 2 (8 %) on the right and 3 (12 %) on the left. There was no difference between the right and left sides in terms of vertical angular values. A significant difference was found between the right and left sides in the D1, D2, D4 distances (p<0.005). Six important anatomical features affecting angular values were encountered.
Para el tratamiento de la neuralgia del trigémino, se alcanza el foramen oval introduciendo una aguja en la mejilla. La termocoagulación se realiza con compresión con balón, administración de alcohol o radiofrecuencia. Aparte del método clásico, en teoría es posible alcanzar el foramen oval a través de la cavidad oral mediante el abordaje anterior. En nuestro estudio se tuvo como objetivo examinar horizontal y verticalmente los valores angulares que se deben dar a la aguja para alcanzar el foramen oval en el abordaje anterior. Se determinaron tres puntos de referencia en los lados derecho e izquierdo de 25 cráneos secos. Se insertó una varilla comenzando desde estos puntos de referencia y pasando por el centro del foramen oval. Se midieron los valores angulares verticales y horizontales de esta barra. Para cada foramen oval se realizaron mediciones de 3 ángulos verticales, 3 ángulos horizontales y 4 distancias. Hubo una diferencia significativa entre los lados derecho e izquierdo en términos de valores angulares horizontales. Valores medios de ángulos horizontales (en grados); a la derecha, 7,29 para H1, 12,15 para H2, 32,29 para H3; 1,26 para H1, 9,46 para H2 y 30,56 para H3 en el lado izquierdo (p<0,005). El valor del ángulo se midió como 0 o valor negativo en 5 (20 %) de las mediciones del ángulo H1 realizadas en el lado derecho y 14 (56 %) en el lado izquierdo. Se encontró que el valor del ángulo H2 era menor que el ángulo H1 en el cráneo 2 (8 %) a la derecha y 3 (12 %) a la izquierda. No hubo diferencia entre los lados derecho e izquierdo en términos de valores angulares verticales. Se encontró diferencia significativa entre el lado derecho e izquierdo en las distancias D1, D2, D4 (p<0,005). Se encontraron seis características anatómicas importantes que afectan los valores angulares.

Unlike the traditional surgical approach, which requires priority treatment of the perihepatic ligament and rotation of the liver, the anterior approach to the right hemicolectomy does not deal with the perihepatic ligament prior to parenchymal dissection and rotate and move the liver. The advantage is that it is more in line with the tumor-free principle and reduces unnecessary free. The disadvantage is that it is relatively difficult to control bleeding during the cleavage of the liver and there is some risk in the handling of the lower part of the vena cava sulcus. However, with the popularization and application of laparoscopy, it is more suitable for performing anterior approach right hemicolectomy than open surgery due to its unique caudodorsal view advantage, finer local anatomical structure display and subtle manipulation. This article discusses the procedures and technical points of laparoscopic right hemihepatectomy through the anterior approach.
ABSTRACT
OBJECTIVE@#To investigate the effect of different postures on direct anterior approach(DAA) total hip arthroplasty.@*METHODS@#Total of 94 patients who underwent DAA total hip arthroplasty from July 2016 to June 2020 were retrospectively analyzed. They were divided into two groups according to different positions during the operation, including 45 cases in lateral position and 49 cases in supine position (with the aid of stent). The general data such as gender, affected limb, body mass index(BMI), incision length, operation time, intraoperative bleeding volume, drainage volume 24 hours after operation, hemoglobin difference before and after operation, first landing time after operation, postoperative hospitalization time, postoperative complications, visual analogue scale(VAS) at 1 day, 1, 2 weeks, 1, 3 and 6 months after operation, Harris score at 1, 2 weeks, 1, 3 and 6 months after operation were observed and compared between the two groups.@*RESULTS@#Patients in both groups were followed up for 6 to 12 months with an average of (8.31±2.22) months. There was no significant difference between two groups in gender, affected limb, age, height, weight, body mass index(BMI), preoperative VAS score and preoperative Harris score(P>0.05). The incision length, operation time, intraoperative bleeding volume, 24-hour drainage volume, hemoglobin difference before and after operation, first time to the ground and postoperative hospitalization time of patients in supine position (assisted by stent) group were all better than those in lateral position group(P<0.05);There was no significant difference in the number of blood transfusions during and after operation(P=0.550). There was no significant difference in anteversion angle and abduction angle in the supine position(with the aid of stent) group during and after operation (P=0.825, P=0.066);There was significant difference in anteversion angle and abduction angle in the lateral position group during and after operation(P<0.05). VAS of patients in supine position (assisted by stent) group were lower than those in lateral position group at 1 day, 1, 2 weeks and 1 month after operation(P<0.05), and there was no statistical difference between two groups at 3 and 6 months after operation(P>0.05). Harris scores of patients in supine position(assisted by stent) group were higher than those in lateral position group at 1 week, 1 month and 3 months after operation(P<0.05), and there was no significant difference between two groups at 6 months after operation(P>0.05).@*CONCLUSION@#Compared with the lateral position, the supine position DAA total hip arthroplasty has the advantages of small incision, short operation time, less bleeding, early landing time, short hospitalization time, and small intraoperative acetabular cup position judgment error. It has the advantage of fast postoperative recovery, but the recovery of hip joint function is the same after 6 months.

ABSTRACT
@#Introduction: Many surgical approaches have been described for hip hemiarthroplasty (HHA) treating femur neck fractures (FNFs). Direct lateral approach (DLA) is one of the most used. Today, the direct anterior approach (DAA) has become very attractive, but it seems to involve more intra-operative fractures. Our main endpoint was to demonstrate that the DAA may be a valid alternative comparing to the DLA. Materials and methods: Patients affected by FNFs and treated with HHA between the years 2016 and 2020 were studied. We divided the treatment of the fractures according to the surgical approach. The analysis was focused on perioperative complications and radiological outcomes. Results: There were a total of 166 patients. The DLA group included patients with an average age of 83.5 years and the DAA group of 83 years. We found similar surgical times (DLA 67 min vs DAA 61 min; p = 0,55), number of transfusions (DLA 3/person vs DAA 4/person; p = 0,91), perioperative complications (fractures: DLA 0 vs DAA 0 – dislocations: DLA 2,50% vs DAA 0) and functional outcomes (HHS: DLA 83 points vs DAA 87 points; p = 0,71). There were no statistical differences comparing diaphyseal filling (Canal Fill Index at the proximal third: DLA 0,79 vs DAA 0,78; p= 0,24), bone loss (Paprosky I: DLA 96,25% vs DAA 91,86%; p = 0,47) and prevalence of heterotopic ossification (Broker low degree: DLA 93,75% vs 95, 34%; p = 0,87). Conclusion: Analysing perioperative complications and studying post-operative radiographic evolution, our results suggest that the DAA is a valid alternative to the DLA in HHA treating FNFs.
ABSTRACT
La artroplastia de cadera es uno de los tratamientos quirúrgicos más exitosos en la cirugía ortopédica. Actualmente existe un mayor interés en el abordaje anterior para artroplastias de cadera determinado por la creencia de que al ser intermuscular puede provocar una disminución del dolor, una recuperación más rápida, mejor estabilidad de la cadera y menor riesgo de luxación después de la cirugía comparativamente. Es propósito de este artículo revisar la historia del abordaje anterior de la articulación de la cadera, su vía intermuscular de acceso y los principales beneficios que posee. Popularizado por Smith-Petersen en 1917, el abordaje anterior de la cadera debe su primera referencia escrita a Carl Hueter. Todos los abordajes de la cadera han demostrado ser seguros y eficaces, con ventajas y desventajas. Se requieren estudios a largo plazo de un mayor número de pacientes para demostrar un beneficio de costo y una mayor calidad en la atención médica(AU)
Hip replacement is one of the most successful surgical treatments in orthopedic surgery. There is currently greater interest in the anterior approach to hip arthroplasties determined by the belief that being intramuscular it can lead to less pain, faster recovery, better hip stability and comparatively less risk of dislocation after surgery. The purpose of this article is to review the history of the anterior approach to the hip joint, its intramuscular access route and its main benefits. Popularized by Smith-Petersen in 1917, the anterior approach to the hip owes its first written reference to Carl Hueter. All hip approaches have been shown to be safe and effective, with advantages and disadvantages. Long-term studies of larger numbers of patients are required to demonstrate cost benefit and higher quality of medical care(AU)

Introducción: Existe una gran controversia con respecto a la existencia de un abordaje quirúrgico óptimo para artroplastia de cadera. El énfasis actual en la investigación ha sido examinar las posibles diferencias en los resultados funcionales entre el abordaje anterior y el abordaje posterior. Objetivo: Comparar las medidas de resultado informadas por los pacientes sometidos a artroplastia total de cadera, mediante abordajes anterior y posterior. Métodos: Se realiza una búsqueda sobre el tema en la base de datos PubMed entre los años 2010-2020 en inglés con los términos: comparación entre abordaje anterior y abordaje posterior de la cadera, abordaje anterior directo de la cadera, abordaje posterior de la cadera, y resultados de artroplastia de la cadera mediante abordajes anterior y posterior. Análisis y síntesis de la información: El abordaje anterior muestra una mayor mejora en la velocidad de la marcha, la longitud del paso y la simetría de la marcha, en comparación con el abordaje posterior para artroplastia de cadera al mes después de la operación. A los cuatro meses estas características de la marcha no fueron diferentes, pero los resultados de algunas pruebas funcionales fueron superiores en los pacientes intervenidos por abordaje anterior. Conclusiones: La elección del abordaje quirúrgico para artroplastia de cadera debe basarse en los factores del paciente, la preferencia del cirujano y su experiencia(AU)
Introduction: There is great controversy regarding the existence of an optimal surgical approach for hip arthroplasty. The current research emphasis has been to examine the possible differences in functional outcomes between anterior and posterior approaches. Objective: To compare the outcome measures reported by patients undergoing total hip arthroplasty, using anterior and posterior approaches. Methods: A search is carried out on the subject in the PubMed database during the years 2010-2020, in English, with the terms comparison between anterior approach and posterior approach to the hip, direct anterior approach to the hip, posterior approach to the hip, and results of hip arthroplasty using anterior and posterior approaches. Analysis and synthesis of the information: The anterior approach showed greater improvement in gait speed, stride length and gait symmetry, compared to the posterior approach for hip arthroplasty one month after the operation. At four months, these gait characteristics were not different, but the results of some functional tests were superior in patients operated on by anterior approach. Conclusions: The choice of the surgical approach for hip arthroplasty should be based on the patient´s factors, preference of the surgeons and their experience(AU)

Background:Central venous catheterization is a vital intervention in critically ill patients. The purpose of this study was to compare the procedural parameters and complications associated with anterior and posterior approaches of IJV catheterization under real timeultrasound guidance in critically ill patients. Material And Methods:In this prospective randomised study, 90 patients admitted in various ICUs were randomly allocated two groups of 45 each, including both males and females aged between 18 to 80 years ofage requiring central venous catheterization for various indications. Result:The first attempt success rates were comparable between both the groups. The venous visualization time was 38.52 seconds in Group A and 14.65 seconds in Group P (p<0.001). The venous puncture time and the duration of catheterization was found to be 47.60 sec & 2 minutes in Group A respectively and 24.16 sec & 1 minute 32 sec in Group P respectively (p<0.001). No statistically significant differences were found between the two groups in terms of incidence of carotid arterial puncture, haematoma formation and catheter displacement.Conclusion:It was observed that the posterior approach is better than anterior approach of USG guided IJV catheterization as it improves the accuracy, reduces the access time and duration of catheterization & leads to fewer incidences of immediate complications like carotid arterial puncture & subseque nt haematoma formation.
ABSTRACT
Objective:To investigate the safety and feasibility of modified pararectus abdominis approach in the anterior plate fixation of sacral fractures.Methods:In 5 fresh adult cadavers (3 males and 2 females), gross anatomy was performed on one pelvic side using a modified pararectus abdominis approach to clarify the anatomical structures around the approach. On the other side of the pelvis, the anterior structures of the sacrum were exposed in simulated anterior plate fixation of sacral fracture via the modified pararectus abdominis approach. The exposed anatomic range of the approach, and the locations and courses of lumbosacral trunk nerve and iliac vessels were observed and recorded.Results:(1) The modified pararectus abdominis approach exposed the whole S1 vertebral body from the sacroiliac joint to the medial side, the L5 vertebral body cephalally, the S1 foramina in the true pelvis, and the same structures laterally as a traditional pararectus abdominis approach did. (2) Via the modified pararectus abdominis approach, exploration and decompression of the lumbosacral plexus (from L4 to S1) (including S1 foraminoplasty) were performed under direct vision to decompress the nerve entrapment from anterior compressed fracture fragments and hyperplastic callus. (3) There was a safe surgical area in anterior L5 and S1 where a plate could be safely fixed to the S1 vertebral body. (4) Since the maximum vertical distance from the lumbosacral trunk nerve lifted above the periost to the sacral ala was 1.4 cm (range, from 1.2 to 1.5 cm), a plate could be safely placed from the subperiosteum to the S1 vertebral body to fix the fracture.Conclusions:The modified pararectus abdominis approach is safe and feasible for exploration and decompression of lumbosacral nerves in the anterior sacral region (from L4 to S1) because it has significant advantages in vision and operation. It also broadens the range of anterior sacral plate fixation because a sacral fracture displacement can be reduced under direct vision and a plate can be fixated to the S1 vertebral body along the alae sacralis and across the sacroiliac joint to the iliac bone.
ABSTRACT
OBJECTIVE@#To investigate the application value of liquid crystal digital display goniometer in total hip arthroplasty.@*METHODS@#From January 2018 to December 2019, 83 patients underwent primary total hip arthroplasty, including 28 males and 55 females, aged 42 to 81 (70.4±7.9) years. There were 63 cases of femoral neck fracture and 20 cases of avascular necrosis of femoral head. All patients used liquid crystal digital goniometer to control the anteversion of acetabular cup prosthesis during operation, and CT scanning was used to measure the anteversion of acetabular cup after operation. The two methods were compared to understand the accuracy of using liquid crystal digital goniometer.@*RESULTS@#Postoperative CT measurement showed that the acetabular anteversion of all patients was in the safe area advocated by Lewinnek. The anteversion angle of acetabular cup measured by liquid crystal digital goniometer was 14.20(12.80 to 15.40)°, and the anteversion angle of acetabular cup measured by postoperative CT scan was 14.20 (13.40 to 15.50)°. There was no significant difference between the two (@*CONCLUSION@#It is an accurate and reliable method to control the anteversion of acetabular cup with liquid crystal digital display angle instrument, which has a good auxiliary reference value.

BACKGROUND: In China, although microscope-assisted anterior cervical decompression has been performed by many spine surgeons in recent years, the application of microscope still needs to be further promoted in China. Therefore, it is necessary to systematically evaluate and analyze the clinical efficacy of cervical spondylopathy by comparing patients under microscope-assisted anterior cervical approach to traditional anterior cervical approach. As a result, it can provide the evidence for clinical decision in these cervical spondylopathy patients. OBJECTIVE: To systematically evaluate the effect between microscope-assisted anterior cervical approach and traditional anterior cervical approach in cervical spondylopathy patients. METHODS: Databases such as Medline, Embase, PubMed, Web of science, CBM, Wangfang databases, VIP, and CNKI were searched from inception to July 2019 to find literature related to microscope-assisted anterior cervical approach and traditional anterior cervical approach in treatment of cervical spondylopathy. Two investigators evaluated the researches independently and compared the operative time, intraoperative blood loss, the preoperative and postoperative Japanese Orthopedic Association score, neurological success rate, the preoperative and the postoperative visual analogue scale score, and the complication rates between two groups. The quality of the included literature was evaluated by the modified Jadad scale, the modified Newcastle Ottawa score and the methodological index for non-randomized-studies. The correlative clinical outcome in inclusive research was analyzed systematically by using Stata 12.0 Software. RESULTS AND CONCLUSION: (1) Twelve studies were accorded with the inclusion criteria, containing 892 cases (438 cases in the microscope-assisted group, while 454 cases in the traditional group). (2) There were no significant differences in the preoperative Japanese Orthopedic Association score (WMD=-0.100, 95%C/(-0.459, 0.259), P=0.585), operative time (WMD=6.852, 95%C/(-0.446, 14.149), P=0.066), the preoperative and postoperative visual analogue scale score (WMD=0.293, 95%C/(-0.023, 0.608), P=0.069; WMD=-0.T\8, 95%C/(-1.495, 0.059), P=0.070) between two groups. (3) Postoperative Japanese Orthopedic Association score (WMD= 1.310, 95%C/(0.621, P < 0.001), the rate of neurological success (WMD-4.639, 95%C/(0.294, 8.984), P=0.036) in the microscope-assisted group were higher than those in the traditional group. The intraoperative blood loss (l/MMD=-18.068, 95%C/(-24.504, -11.632), P< 0.001) and the rate of complication (RR=1.068, 95%C/(1.012,1.126), P=0.002) in the microscope-assisted group were significantly lower than those in the traditional group. (4) Performing anterior cervical approach under microscope has a better clinical effect than using traditional anterior cervical approach in the treatment of cervical spondylopathy, but more high-quality clinical studies are needed to verify it.
ABSTRACT
BACKGROUND: Total hip arthroplasty can significantly alleviate pain in patients with end-stage hip disease and improve the joint function. Different surgical approaches have their own advantages and disadvantages. As a popular approach, direct anterior approach is to expose the hip joint through the fascia lata muscle and the sartorius muscle gap, which is in line with the concept of minimally invasive surgery, and has the advantages of small damage to soft tissue and quick recovery after arthroplasty. However, it has a certain learning curve, which requires the surgeons to have certain experience. OBJECTIVE: To compare the perception of the elderly with unilateral femoral head fracture undergoing total hip arthroplasty through direct anterior approach and anterolateral approach. METHODS: Forty-two patients (42 hips) with unilateral femoral head fracture in Orthopedic Center, Xinjiang Uygur Autonomous Region People’s Hospital from January 2017 to June 2018 were enrolled, and all patients underwent total hip arthroplasty. The patients were randomized into two groups, including 21 patients (21 hips) in anterolateral approach group and 21 patients (21 hips) in direct anterior approach group. The patients signed the informed consents and the study was approved by the Hospital Ethics Committee. The incision length, operation time and blood loss were recorded. The Harris hip joint score, and Oxford Hip scores at 1 week, 1 and 3 months postoperatively were compared. The prosthesis location and complications were observed. RESULTS AND CONCLUSION: (1) The hospitalization time in the direct anterior approach group was significantly shorter than that in the anterolateral approach group (P 0.05). (4) The Harris hip and Oxford Hip scores at 1 week after surgery in the direct anterior approach group were significantly higher than those in anterolateral approach group (P 0.05). (5) One case in the direct anterior approach group and two cases in the anterolateral approach group appeared with bursitis surrounding with the incision and pain, which disappeared after local sealing. One patient in the direct anterior approach group developed subcutaneous hematoma, and healed at postoperative 3 weeks. One case in the direct anterior approach suffered from inner thigh skin numbness. (6) These results indicate that at early postoperative period, patients in anterolateral approach group are feeling better than those in direct anterior approach group. Although direct anterior approach has the advantages of small incision, less pain at the early postoperative period and fast recovery, it has a certain learning curve, with a longer operation time and more blood loss.
ABSTRACT
BACKGROUND: Ulnar coronoid process has special anatomy and it is adjacent to vascular nerve. It is characterized by weak fixation, unstable recurrence, postoperative elbow joint stiffness and pain. These make the treatment of ulnar coronoid process fracture, in particular in complex elbow joint injuries, challenged. OBJECTIVE: To investigate the efficacy of internal fixation with steel plate through an anterior approach on ulnar coronoid process Regan-Morrey type II or type III fracture in complex elbow injury METHODS: Sixteen patients with complex elbow injury and ulnar coronoid process fractures who underwent open reduction and internal fixation were followed up between September 2012 and May 2017. Among these patients, 11 patients had Regan-Morrey type II fracture, 5 patients had Regan-Morrey type III fracture, 14 patients had humeral head fracture, and 2 patients had ulnar olecranon fracture. All patients provided written informed consent. This study was approved by the Medical Ethics Committee of Hong Hui Hospital, China. Ulnar coronoid process fractures were reduced and fixed with steel plate through the space between the median nerve and the radial artery using an anterior approach. At the same time, all radial humeral head and olecranon fractures were treated by internal fixation. RESULTS AND CONCLUSION: All patients acquired acceptable reduction and firm fixation of fractured fragments. All of them were followed up for 13-28 months. At the final follow-up, solid osseous union was confirmed for all coronoid fractures. The average time to radiologic union was 16.5 weeks. The mean flexion-extension arc was 113.4°, the flexion contracture was 13.8°, and further flexion was 127.2°. The mean pronation arc was 72.5°. The mean supination arc was 74.7°, and the mean forearm rotation arc was 146.9°. 11 patients achieved functional arc of motion. All patients were satisfied with the treatment with the mean Mayo Elbow Performance score of 90.3 points. 11 patients achieved excellent elbow performance and 5 patients achieved good elbow performance. These results suggest that ulnar coronoid process fractures in complex elbow injury can be treated successfully with an anterior surgical approach. This approach allows for accurate and rigid internal fixation with steel plate and early functional exercise, resulting in a reasonable outcome.
ABSTRACT
BACKGROUND: With the comprehensive promotion of spinal internal fixation technology, the remodeling of spinal mechanical stability has attracted more and more attention. Lateral internal fixation via axillary midline transthoracic approach for the treatment of upper thoracic vertebra lesion is a new surgical approach. Currently, the research on the biomechanics of upper thoracic vertebra after fixation is relatively rare. OBJECTIVE: To evaluate whether the reconstruction of upper thoracic vertebrae via axillary midline transthoracic approach can achieve the requirements of biomechanical stability by biomechanical analysis of three-dimensional motion stability and load-bearing strength of upper thoracic vertebrae in lateral and anterior internal fixation models. METHODS: The C7-T6 spine and bilateral rib cage joint specimens were obtained from 12 human cadaveric bodies, and the three-dimensional motion stability test of the complete upper thoracic vertebrae model was performed and recorded as a complete vertebral body group. Subsequently, the specimens were randomly divided into two groups, and the traditional front plate internal fixation (front internal fixation group) and the axillary line into the thoracic cavity side plate internal fixation models (lateral internal fixation group) were established, respectively, with six specimens in each group. Three-dimensional motion test, vertical pressure test and vertical pressure failure test were performed. This study was approved by the Ethics Committee of Second Affiliated Hospital of Guangxi Medical University (approval No. 2017(KY-0080)). RESULTS AND CONCLUSION: (1) The load of left vertebral body group under left/right flexion, flexion/posterior extension and left/right rotational motion was smaller than that of lateral internal fixation group and anterior internal fixation group (P 0.05). (2) When the load reached 600 N, the vertebral body sinking displacement of the front internal fixation group was smaller than in the lateral internal fixation group [(1.39±0.20), (2.15±0.17) mm, P< 0.01]. (3) There was no significant difference in the maximum intensity load between the anterior internal fixation group and the lateral internal fixation group [(1 839.70±122.45), (1 798.65±120.21) N, P=0.571], (4) Results showed that the axillary midline transthoracic approach was in the lateral steel plate. The fixation is stable and meets the biomechanical needs of spinal reconstruction.
ABSTRACT
BACKGROUND: The posterolateral approach is the most commonly used surgical approach for total hip arthroplasty. In recent years, total hip replacement by direct anterior approach has been applied in clinic gradually, and has achieved good treatment outcomes. OBJECTIVE: To compare the clinical efficacy of the direct anterior approach in supine position and the posterolateral approach in supine position for total hip arthroplasty. METHODS: Ninety patients undergoing unilateral primary total hip arthroplasty at Baoding Municipal First Center Hospital from April 2015 to April 2019 were included, including 35 males and 55 females, aged 35-70 years. The patients were divided into direct anterior approach group (n=45) and posterolateral approach group (n=45) by the random number table method. Postoperative follow-up was used to evaluate the Harris hip scores, Visual Analogue Scale scores, initial fixation mass of prosthesis and safe range of the cup. The study was approved by the Ethics Committee of Baoding Municipal First Center Hospital. RESULTS AND CONCLUSION: (1) Ninety patients were followed up for 3-51 months, with an average 14 months. There were 2 cases of intraoperative great trochanteric fracture, 1 case of femoral lateral cutaneous nerve injury, 4 cases of femoral nerve injury, and 20 cases of tensor fascia lata injury. No such complications occurred in the posterolateral approach group. (2) The direct anterior approach group showed significant superior outcomes compared with the posterolateral approach group in the Harris hip scores and Visual Analogue Scale scores at 1 month after surgery (P 0.05). (3) In the direct anterior approach group, the femoral prosthesis of 44 hips was in neutral position, and 1 hip was in varus position. The initial fixation quality of all prosthesis was excellent. In the posterolateral approach group, the femoral prosthesis of 43 hips was in neutral position, 2 hips were in varus position and all prosthesis initial fixation quality was excellent. No significant difference was found between two groups (P > 0.05). (4) The ratio of acetabular cups in the safety range of Lewinnek in the direct anterior approach group was higher than that in the posterolateral approach group (100%, 82%, P < 0.05). (5) These results imply that compared with the posterolateral approach, direct anterior approach in supine position for total hip arthroplasty can significantly reduce postoperative pain, promote postoperative early rapid recovery, obtain more accurate angle of the acetabular prosthesis, and be more conducive to the equalization of both lower limbs. It is a safe and reliable approach. However, direct anterior approach has certain technical difficulty and needs a learning curve. And there are some complications different from other approaches.
ABSTRACT
BACKGROUND: With the trend of minimally invasive and “rapid rehabilitation” in modern surgery, direct anterior approach is preferred by orthopedic surgeon in recent years. OBJECTIVE: To review the direct anterior approach’s history, surgical indications, patients’ selection, surgical methods, common complications, surgery advantages and learning curves, to provide ideas for the rapid rehabilitation of hip arthroplasty. METHODS: PubMed, Wanfang database, and CNKI were retrieved for articles addressing total hip arthroplasty through direct anterior approach published from 1956 to 2020. Key words were minimally invasive, direct anterior approach, total hip arthroplasty, enhanced recovery after surgery, complication, learning curve” in Chinese and English. Finally, 67 articles met the criteria for review. RESULTS AND CONCLUSION: (1) The direct anterior approach is an ideal minimally invasive surgical path because of it walks in the fascia gap and it is a truly neuromuscular interface with no damage to important muscles and nerve blood vessels. (2) Direct anterior approach has advantages of quicker recovery, less postoperative pain, short hospital stay and high patient satisfaction. However, because most doctors in our country have changed their surgical approach to direct anterior approach, direct anterior approach still has shortages, such as long learning curve and high rate of early complications.
