ABSTRACT
Las fracturas acetabulares con compromiso del cartílago trirradiado (CTR) en pacientes pediátricos son muy poco frecuentes, difíciles de diagnosticar y complejas de tratar; pudiendo dejar graves secuelas. Generalmente son producto de accidentes de tránsito de alta energía cinética. Debido a su baja prevalencia no hay grandes series en la bibliografía y por ende tampoco existe un consenso terapéutico. Realizamos una puesta a punto del tema a propósito de un atípico caso de una niña de 9 años con una fractura del acetábulo con compromiso del CTR, producido por un traumatismo de baja energía cinética. Registramos su diagnóstico y tratamiento quirúrgico, evaluamos su resultado clínico - radiológico y funcional mediante el Hip Harris Score (HHS) al final de su seguimiento de 5 años.
Acetabular fractures with compromise of the triradiate cartilage (TRC) in pediatric patients are very rare, difficult to diagnose and complex to treat, also can leave serious consequences. They are generally product of high energy kinematics. Due to its low prevalence, there are no large series in the literature and therefore there is no therapeutic consensus. We carried out a recapitulation of the subject regarding an atypical case of a 9-year-old girl with an acetabulum fracture with compromise of the TRC, produced by a low kinetic energy trauma. We recorded the diagnosis and surgical treatment, and also, we evaluated the clinical-radiological and functional results through the Hip Harris Score (HHS) at the end of their 5-year follow-up.

OBJECTIVE@#To investigate the surgical technique and effectiveness of titanium elastic nail (TEN) assisted retrograde channel screw implantation of superior pubic branch.@*METHODS@#The clinical data of 31 patients with pelvic or acetabular fractures treated with retrograde channel screw implantation in superior pubic branch between January 2021 and April 2022 were retrospectively analyzed. Among them, 16 cases were implanted with assistance of TEN (study group) and 15 cases were implanted under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification of pelvic fracture, Judet-Letournal classification of acetabular fracture, and time from injury to operation between the two groups ( P>0.05). The operation time, fluoroscopy times, and intraoperative blood loss of each superior pubic branch retrograde channel screw were recorded during operation. X-ray films and three-dimensional CT were reexamined after operation, the quality of fracture reduction was evaluated by Matta score standard, and the position of channel screw was evaluated by screw position classification standard. The fracture healing time was recorded during the follow-up, and the postoperative functional recovery was evaluated by Merle D'Aubigne Postel score system at last follow-up.@*RESULTS@#Nineteen and 20 retrograde channel screws of superior pubic branch were implanted in the study group and the control group, respectively. The operation time, fluoroscopy times, and intraoperative blood loss of each screw in the study group were significantly less than those in the control group ( P<0.05). According to the postoperative X-ray films and three-dimensional CT, none of the 19 screws in the study group penetrated out of the cortical bone or into the joint, and the excellent and good rate was 100% (19/19); in the control group, there were 4 screws of cortical bone penetration, and the excellent and good rate was 80% (16/20); the difference between the two groups was significant ( P<0.05). Matta score standard was used to evaluate the quality of fracture reduction, there was no patient in the two groups with poor reduction results, and the difference was not significant between the two groups ( P>0.05). The incisions of the two groups healed by first intention, and there was no complication such as incision infection, skin margin necrosis, and deep infection. All patients were followed up 8-22 months, with an average of 14.7 months. There was no significant difference in healing time between the two groups ( P>0.05). At last follow-up, the difference in functional recovery evaluated by the Merle D'Aubigne Postel scoring system between the two groups was not significant ( P>0.05).@*CONCLUSION@#TEN assisted implantation technique can significantly shorten the operation time of retrograde channel screw implantation of superior pubic branch, reduce the times of fluoroscopy, and have less intraoperative blood loss and accurate screw implantation, which provides a new safe and reliable method for minimally invasive treatment of pelvic and acetabular fractures.

Old unreduced and untreated fracture of the acetabulum is seen more commonly in developing countries and can be due to various reasons. Various methods can be used in the management of such cases which in general includes arthrodesis in young and total hip replacement in elderly patients. Acetabular fractures associated with acetabular defect pose challenge to the treating surgeon and the management of such defects plays an important role in the ?nal outcome of the surgery. We are here reporting a case of a 36 years old male patient who presented with 1 year 6 months old fracture of posterior wall of the acetabulum who is treated with THR with acetabular reconstruction using bone graft and acetabular augment. The patient was under regular follow up and now after 6 months of surgery patient is having good functional improvements with painless range of motions at index hip
ABSTRACT
ObjectiveTo evaluate the efficacy and safety of a perioperative rehabilitation clinical pathway of acetabular fracture in light of orthopedics rehabilitation team approach. MethodsA prospective randomized control trial was conducted in 82 patients with acetabular fractures who had been admitted from the Emergency Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from June, 2019 to January, 2021. The patients were randomly divided into control group (n = 41) and intervention group (n = 41). The control group was managed routinely, while the intervention group received the rehabilitation clinical pathway, for 24 weeks. The Visual Analogue Score (VAS) of pain, the Barthel Index (BI) and Majeed Pelvic Score were compared. ResultsFinally, 76 patients completed the trial. There was no statistical difference in VAS score between two groups in all periods (|Z| < 1.926, P > 0.05). The BI score was higher in the intervention group than in the control group at discharge, two weeks, six weeks and twelve weeks after operation (|Z| > 2.121, P < 0.05); and no significant difference was found before operation and 24 weeks after operation (|Z| < 1.862, P > 0.05). Majeed Pelvic Score was higher in the intervention group than in the control group two weeks, six weeks, twelve weeks and 24 weeks after operation (|Z| > 2.428, P < 0.05). Six, twelve and 24 weeks after operation, the excellent rate of Majeed Pelvic Score was higher in the intervention group than in the control group (χ2 > 6.136, P < 0.05). ConclusionIn comparison with traditional protocol in acetabular fracture, the perioperative rehabilitation clinical pathway was proved effective and of great safety in the light of the integration of orthopedics and rehabilitation mode for improving the function and activities of daily living of patients.
ABSTRACT
BACKGROUND: Studies have shown that there are differences in the biomechanics of different internal fixation methods to fix the acetabular posterior column fracture. OBJECTIVE: To simulate the acetabular posterior column fracture and evaluate the stability of the acetabular posterior column with three fixation methods. METHODS: Thirty-six cadaveric hemipelvic specimens were collected to establish models of acetabular posterior column fracture. The models were randomly divided into three groups, and were fixed by three different fixation methods: (short iliosciatic plate in group A, traditional posterior plate in group B, and long iliosciatic plate in group C; n=12 per group). Mechanical loads were applied vertically in standing and sitting positions. The fracture ends displacement and biomechanical stability were evaluated by using image displacement method. RESULTS AND CONCLUSION: (1) In the standing position, the relative displacement of the fracture ends of the three groups was positively correlated with the load; there was no statistically significant difference in the displacement of the fracture ends under the same load in the three groups (P > 0.05). When loaded with a load of 1 800 N, the relative displacement of each group of models did not exceed 3 mm. (2) In the sitting position, the relative displacement of the fracture end was positively correlated with the size of the load; the relative displacement of the three groups under the same load was significantly different (P < 0.05). Under the same load, the relative displacement of group B was greater than that of groups A and C; the relative displacement of group A under 100-500 N load was greater than that of group C, and the relative displacement under 600 N load was smaller than that of group C. (3) The results suggested that the iliosciatic plate fixation of the acetabular posterior column fracture can provide the same biomechanical stability as the traditional posterior column steel plate, and the rigidity of the fixed structure is high, which can meet the postoperative rehabilitation needs.
ABSTRACT
@#Introduction: Approach to the management of displaced acetabular fractures has evolved from conservative to operative management after the work of Judet and Letournel. Various surgical methods have been explored and described by authors to address this type of fracture, leading to improved clinical outcome. This study aimed to evaluate functional outcome of surgically treated displaced acetabular fractures in the Malaysian context. Materials and methods: We analysed 43 patients with isolated acetabular fractures who were treated operatively with a minimum of three years follow-up. Anthropometric data, Judet-Letournel fracture pattern, surgical approach and complications were recorded. Post-operative Matta radiological outcome were evaluated for joint congruency and hip functional outcome was evaluated using Merle d’Aubgine-Postel and Harris Hip Score (HHS). All statistical analyses were analysed using SPSS version 24.0. Results: The most frequent elementary fracture type was posterior wall (30.2%) while associated type was both columns (23.3%). Mean functional outcome of Merle d'Aubigné-Postel was 15.77 and HHS was 86.6. Thirty-three (76.7%) patients achieved satisfactory functional outcome, 19 (44.1%) patients achieved anatomic reduction (<2 mm step-off) based on Matta classification while 24 (55.8%) did not achieve the desired outcome. Fracture pattern exhibited strong association with post-operative Matta radiological outcome (p-value 0.001). However both fracture pattern and Matta radiological outcome did not exhibit association with the functional outcome group. The mean time for surgical interventions was 10.8 days and there was no significant association with final functional outcome score. Conclusion: Fracture pattern is a strong contributing factor towards post-operative Matta radiological outcome. However, achieving the perfect anatomical reduction is not of utmost important factor to predict the good functional outcome.
ABSTRACT
OBJETIVO: Evaluar los resultados radiológicos a corto y mediano plazo de pacientes operados de fractura de pared posterior de acetábulo, describir la morfología de la fractura, presencia de lesiones asociadas y la necesidad de artroplastia total de cadera (ATC) durante la evolución. MATERIAL Y MÉTODOS: Estudio retrospectivo-descriptivo de una serie consecutiva de 40 pacientes operados entre julio de 2012 y julio de 2017 por fractura de pared posterior de acetábulo. Treinta y siete hombres y tres mujeres con una edad promedio de 41 años fueron operados (mediana de seguimiento 17,7 meses). Se registró el mecanismo del accidente y presencia de lesiones asociadas. Se registraron el número de fragmentos que presentaba la fractura, presencia de impactación marginal, compromiso de la cabeza femoral, presencia de fragmentos intra-articulares y complicaciones postoperatorias. Para el análisis estadístico se utilizó el test de Wilcoxon. RESULTADOS: Todos los casos fueron secundarios a un accidente de alta energía. Un 70% de los pacientes presentó luxación posterior. La mayoría de los pacientes presentó una fractura entre 2 y 5 fragmentos (70%), 47,5% de los pacientes presentó impactación marginal, 37,5% compromiso de la cabeza femoral en zona de carga, 30% fragmentos intra-articulares. La complicación que más frecuente se observó fue la artrosis post-traumática la cual se presentó en un 22,5%. Cinco pacientes (12,5%) requirieron ATC. CONCLUSIÓN: Aunque se categorizan dentro de los patrones simples, las fracturas de pared posterior son lesiones complejas. La tomografía axial computada preoperatoria es esencial para determinar lesiones intra-articulares dada su alta frecuencia y también permite realizar un buen plan preoperatorio.
OBJECTIVE: Evaluate radiologic results in short and medium-term in surgically treated patients with acetabular posterior wall fracture. Describe fracture morphology, the presence of associated lesions and the necessity of total hip arthroplasty (THA) during the evolution. MATERIALS AND METHODS: A retrospective-descriptive study design of 40 patients treated during July 2012 and July 2017 for acetabular posterior wall fracture. 37 men and 3 women, 41 years old mean age. The mean follow-up was 17.7 months. Accident mechanism and presence of associated lesions were registered, as well as the number of fragments of the fracture, the presence of marginal impaction, femoral head compromise, intra-articular fragments and postoperatory complications. Wilcoxon test was used for the statistical analysis. RESULTS: Every case resulted due to a high energy accident. 70% of patients had posterior luxation of the hip. 70% of patients presented 2 to 5 fragments. 47.5% of patients presented marginal impaction, 37.5% compromised femoral head and 30% intra-articular fragments. The most frequent complication was post-traumatic arthrosis, which appeared in 22.5% of patients. Five patients required THA. CONCLUSION: Though it is categorized as simple fracture pattern, posterior wall fractures are complex. Preoperatory CT scan is essential to determine intra-articular lesions due to its high frequency and permits to plan an adequate intervention.

ABSTRACT
Objective: To explore the effectiveness of the calcaneal plate bridge reconstruction plate for acetabular fracture involving quadrilateral surface via modified Stoppa approach. Methods: Between January 2015 and December 2017, 18 patients with acetabular fracture involving quadrilateral surface were treated with the calcaneal plate bridge reconstruction plate via the modified Stoppa approach. There were 12 males and 6 females. The age ranged from 28 to 63 years (mean, 39 years). The cause of injury was traffic accident in 13 cases and falling from height in 5 cases. According to the Letournel-Judet classification, there were 10 cases of anterior and posterior column fractures, 6 cases of T-shaped fractures, and 2 cases of anterior column and posterior semi-transevere fractures. The interval from injury to operation was 6 to 24 days (mean, 8.6 days). The reduction quality was assessed by postoperative X-ray film and CT according to the criteria proposed by Matta. The hip joint function was assessed by the modified Merled'Aubigné-Postel score. Results: The operation time was 120-240 minutes (mean, 165 minutes) and the intraoperative blood loss was 600-1 400 mL (mean, 850 mL). All patients were followed up 18-30 months (mean, 24.5 months). There were 2 cases of the fat liquefaction of abdominal incisions, 3 cases of intraoperative injury of lateral femoral cutaneous nerve, 1 case of lower limb thrombosis, and 1 case of abdominal pain and hematuria due to intraoperative accidental bladder injury. According to the criteria proposed by Matta, the reduction quality rated as anatomic reduction in 12 cases, satisfactory reduction in 5 cases, and unsatisfied reduction in 1 case, and the satisfaction rate was 94.4%. All fractures healed with the healing time of 3-5 months (mean, 3.4 months). During follow-up, no internal fixator loosening, breakage, or fracture displacement occurred. At last follow-up, according to modified Merled'Aubigné-Postel score, hip joint functions rated as excellent in 11 cases, good in 4 cases, fair in 2 cases, and poor in 1 case. The excellent and good rate was 83.3%. Conclusion: Application of calcaneal plate bridge reconstruction plate via the modified Stoppa approach for the acetabular fracture involving the quadrilateral surface can obtain satisfactory effectiveness.
ABSTRACT
BACKGROUND: Acetabular fracture is considered to be one of the most challenging fractures because of its complex anatomical structure, which makes it more difficult to treat. At present, open reduction and internal fixation are still the standard treatment methods for displaced acetabular fractures. The patient-specific pre-contour reconstruction template made by three-dimensional (3D) printing technology combined with preoperative virtual surgery plan can reduce the invasiveness of surgery and simplify the operation process. OBJECTIVE: To evaluate the effect of 3D printing combined with virtual surgical planning in the treatment of acetabular fractures compared with traditional reduction and reconstruction of acetabular fractures. METHODS: Totally 25 patients were selected from Affiliated Hospital of Chengde Medical College from October 1, 2017 to March 1, 2018, including 14 males and 11 females, at the age of 21-60 years old. They were divided into experimental group (n=12) and control group (n=13) by computer random grouping method. In the experimental group, printing technology combined with virtual pre-contour reconstruction plate fixation was performed. In the control group, intraoperative contour reconstruction plate fixation was conducted after reduction. Postoperative X-ray and non-contrast CT scan was used to analyze fracture reduction in two groups. After the operation, the patients in the two groups were followed up for visual analogue scale score, Majeed function score and complications. This study was approved by the Ethics Committee of Affiliated Hospital of Chengde Medical College (approval No. LL007). RESULTS AND CONCLUSION: (1) X-ray films showed that the reduction effect of the experimental group was better than that of the control group (P=0.038). Non-contrast CT images showed that the reduction displacement difference of the experimental group was better than that of the control group before and after operation [(12.43±7.58) mm, (9.408±8.27) mm, P < 0.05]. (2) At 6-12 months after surgery, visual analogue scale scores were lower in the experimental group than in the control group [(1,6±0.6), (3.3±1.3), P < 0.05], There were no significant differences in Majeed function scores between the two groups in the final follow-up (P=0.079). (3) Complications, such as delayed healing, failure of internal fixation or deep vein thrombosis, were not found; and no biocompatibility adverse reactions related to the implanted device occurred in the two groups after surgery. (4) Results suggested that 3D printing technology assisted virtual operation plan can improve the reduction quality in the fixation of acetabular fracture, improve the operative effect of acetabular fracture, and reduce the postoperative pain of patients.
ABSTRACT
PURPOSE: The transversely oriented fracture lines are very difficult to reduce during operations, even after clear exposure of the fracture site, in acetabular fractures. The purpose of this study is to verify the quality of reduction between the different subtypes (transtectal, juxtatectal, and infratectal) of transverse fractures. This study also determined the proper type of clamps to use and the proper zone for achieving accurate reductions in Sawbones models. MATERIALS AND METHODS: Six fractures in 3 different subtypes of transverse fractures were artificially created. Ten different reduction clamps were applied for reduction of the fractures. Twelve holes around the fracture were drilled for the maintenance of the clamps. The fracture displacements were measured at the extra-articular area and the intra-articular joint portion. The pictures of the intra-articular fracture displacements were taken by a camera and these were uploaded and analyzed by the TraumaCad® computer program (Brainlab). RESULTS: The reduction quality was poor in order of transtectal, juxtatectal and infratectal. The intraarticular opening was more prominent in the transtectal subtype. The safe zone, when giving consideration of the neurovascular bundles, was a quadrilateral surface of the ilium. Drill holes are useful for maintenance of the reduction clamps. Reduction clamps with points (Weber clamp) were the best for maintenance and accurate reduction. Regarding the concerns of placement of clamps, the middle to posterior combination was the best. The upper hole among the posterior holes in the ilium was the most likely to well reduce the intra-articular opening. CONCLUSION: Transtectal was the more complicated subtype in the aspect of reduction quality. The Weber type reduction clamp was the best for reduction by centrally located holes in the quadrilateral surface and posteriorly located iliac holes in transverse acetabular fractures. The upper hole, among the posterior holes in the ilium, was the best for reduction of the fracture displacements in the intraarticular portion of acetabulum.

Objective To compare the effectiveness of controlling blood loss in the treatment of complex acetabular fracture between temporary occlusion of abdominal aorta by interventional balloon (TOAAIB),temporary occlusion of common iliac artery by interventional balloon (TOCAIIB) and internal iliac artery ligation (IIAL).Methods Included for this study were 113 complex acetabular fractures which had been treated at Department of Orthopaedic Trauma,Shaoguang Hospital Affiliated to Southern Medical University from January 2000 through January 2017.There were 68 males and 45 females,aged from 23 to 61 years (average,42.3 years).According to the Letournel classification,all of them belonged to complex fractures,including 10 T-type,24 double-column,16 posterior column & posterior wall,46 transverse & posterior wall and 15 anterior & posterior half-transverse ones.They were all treated by open reduction and internal fixation but differed in surgical hemostasis techniques:TOAAIB was used in 37cases,TOCAIIB in 31 and IIAL in 45.Fracture reduction was evaluated by Matta criteria.Intraoperative bleeding and postoperative wound drainage,fracture union and complications related to interventions were recorded.Hip function was evaluated by Modified d'Aubigne & Postal clinical grading system after fracture healing.Results The 3 groups (TOAAIB,TOCAIIB and IIAL) were comparable because there were no significant differences in gender,age,time from injury to surgery,Letournel classification or surgical approaches between the patients in the 3 groups (P ＞ 0.05).Anatomical reduction was achieved in 91.15％ of the patients (103/113) and satisfactory reduction in 8.85％ (10/113).Intraoperative hemorrhage was 1,631.5 ±675.5 mL in the HAL group,892.6 ±217.7 mL in the TOCAIIB group and 648.0 ± 170.2 mL in the TOAAIB group,showing significant differences between the 3 groups (P ＜ 0.05).One case of femoral artery thrombosis occurred in the TOAAIB group at the end of operation but was cured by symptomatic treatment of anticoagulation.There were no interventional complications in the other 2 groups.There were no significant differences between the 3 groups in postoperative wound drainage,fracture union time,hip function score or complications (P ＞ 0.05).Conclusions In controlling intraoperative bleeding in the surgery for complex acetabular fracture,TOAAIB may be the best,followed by TOCAIIB,and IIAL may be the worst.However,choice of a proper surgical hemostasis technique should also depend on the specific intraoperative condition of a specific patient.
ABSTRACT
The Letournel-Judet classification system for acetabular fractures is widely used, but there are still some shortcomings, such as incomplete classification and confusion of classification concepts, which cannot effectively guide the treatment. Professor Hou Zhiyong proposed and elaborated an improved acetabular fracture classification system based on the concept of three columns of acetabulum. However, the credibility and repeatability of the classification still lacked validation from clinical data. In this regard, the author included 463 patients with relatively complete imaging data admitted to Third Hospital of Hebei Medical University and Honghui Hospital affiliated to Xi'an Jiaotong University Medical College in the past five years. Four trauma orthopedists classified the patients according to the modified classification method of acetabular fracture. After two months, the original sequence of imaging data was disrupted and re-classified by the same trauma orthopedists. The consistency of the classification was evaluated by Kappa test and compared with Letournel-Judet classification. The results showed that credibility and repeatability of the modified classification were higher than Letournel-Judet classification, suggesting the feasibility of clinical application.
ABSTRACT
Resumen Fractura acetabular bilateral, reducción abierta y fijación interna, sin lograrse reducción anatómica; requirió colocación de prótesis totales a corto plazo, ambas cementadas. Se llevó a cabo una revisión de ambos componentes de cadera izquierda a los ocho años por aflojamiento de la copa y del vástago, con componentes no cementados. El fémur evolucionó de manera satisfactoria, no así el acetábulo, que requirió seis revisiones subsecuentes, con injertos óseos y colocación de refuerzos metálicos, inicialmente muy estables, pero con ruptura de tornillos y falta de osteointegración tanto de los implantes como de los injertos a los 12 y 18 meses en los diferentes eventos quirúrgicos. Desarrolló pseudoaneurisma de la arteria iliaca externa izquierda, tratado por un cirujano vascular; se complicó con infección local primero e infección profunda de cadera izquierda por Staphylococcus aureus después. Se trató con retiro de los implantes en iliaco y utilizando polimetilmetacrilato con antibiótico como relleno del gran defecto óseo mientras se controló la infección, terminando con una prótesis de rescate en silla de montar (Link, Hamburgo). En la actualidad, tiene buena función, sin dolor, pero con movilidad limitada, sobre todo la flexión. La cadera derecha se ha revisado una sola vez; la copa acetabular empezó a migrar cefálica y vertical, pero sin perder estabilidad, al poco tiempo del aflojamiento de la izquierda; nunca desarrolló compromiso del vástago femoral, permitiéndole una función aceptable y siendo «su pierna buena¼ durante el tiempo de disfunción de la cadera izquierda. Se revisó colocando injerto óseo estructural con dos cabezas femorales de cadáver y cementando una nueva copa. La recuperación de la paciente ha sido muy buena; se ha reintegrado a la vida activa, en la que se vale por sí misma para todas sus actividades cotidianas; utiliza una muleta con la mano derecha, maneja una camioneta, no tiene dolor.
Abstract Bilateral acetabular fracture, open reduction and internal fixation, without achieving anatomical reduction; it required placement of short-term total prostheses, both cemented. We made a revision of both left hip components in the eighth year because of loosening of the cup and stem, with uncemented components. The femur evolved satisfactorily, but the acetabulum required six subsequent revisions, with bone grafts and placement of metal reinforcements, initially very stable, but with screw rupture and lack of osseointegration of both implants and grafts at 12 and 18 months in the different surgical events. She developed pseudoaneurysm of the left external iliac artery, treated by a vascular surgeon; it got complicated with local infection first and later, deep infection of the left hip by Staphylococcus aureus. The implants were removed from the iliac and polymethylmethacrylate with antibiotics was used to fill the large bone defect while the infection was being controlled, ending with a saddle rescue prosthesis (Link, Hamburg). It currently has a good function, without pain, but with limited mobility, especially flexion. The right hip has only been checked once; the acetabular cup began to migrate cephalically and vertically, but without losing stability, shortly after the loosening of the left one; it never developed femoral stem involvement, allowing acceptable function and being «her good leg¼ during the time of the left hip dysfunction. It was reviewed by placing a structural bone graft with two femoral heads from a corpse and cementing a new cup. The patient's recovery has been very good, returning to an active life in which she is self-sufficient in all her daily activities; uses a crutch with her right hand, drives a van, is pain-free.
ABSTRACT
Background: Acetabular fracture remains as a major challenge to orthopaedic surgeons despite of decades of improvement in its operative management. Unfavorable reduction is considered one of the key factors leading to joint degeneration and compromised clinical outcome in acetabular fracture patients. Besides the columns, walls, and superior dome, the postoperative position of hip joint center (HJC), which is reported to affect hip biomechanics, should be considered during the assessment of quality of reduction. Objectives: In this study, we aimed to quantify the postoperative shift of HJC radiographically, and to evaluate the relationship between the shift of HJC and the quality of fracture reduction following ORIF of acetabular fractures. Material and Methods: Patients with a displaced acetabular fracture that received open reduction and internal fixation in the authors institution during the past three years were identified from the trauma database. The horizontal and vertical shifts of HJC were measured in the standard anteroposterior view radiographs taken postoperatively. The radiographic quality of fracture reduction was graded according to Matta’s criteria. The relationships between the shift of HJC and the other variables were evaluated. Results: Totally 95 patients with 36 elementary and 59 associated-type acetabular fractures were included, wherein the majority showed a medial (92.0%) and proximal (94.0%) shift of HJC postoperatively. An average of 2.9 mm horizontal and 2.3 mm vertical shift of HJC were observed, which correlated significantly with the quality of fracture reduction (P < 0.001 for both). The horizontal shift of HJC correlated with the fracture type (P = 0.022). Conclusion: The restoration of HJC correlates with the quality of reduction in acetabular fractures following open reduction and internal fixation. Further studies are required to address the effects of HJC shift on the biomechanical changes and clinical outcomes of hip joint, especially in poorly reduced acetabular fractures.

ABSTRACT
PURPOSE: This study is performed to evaluate the usefulness of arthroscopic surgery prior to open reduction and fixation surgery to treat acetabular fractures and hip fractures-dislocation. MATERIALS AND METHODS: From January 2010 to March 2014, a total of 54 patients with acetabular fractures or hip fractures with dislocation were treated arthroscopically via fracture surface before open reduction and fixation (group 1, n=11), and without hip arthroscopy prior to open reduction and fixation (group 2; n=43). Clinical results were evaluated using Harris hip score (HHS) and visual analogue scale (VAS) pain scores. RESULTS: The mean age of patients is 43.2 years and there are 10 males and 1 females in group 1. The mean follow-up period is 15 months. The acetabular status of each case was assessed arthroscopically. Bone fragment was performed in 6 cases, and ligamentum teres shrinkage in 1 case. At the final follow up, the mean HHS and VAS pain scores were 78.6 and 2.18, respectively. During follow up, one case of osteoarthritis and one case of heterotopic ossification were identified. At the final follow up, the mean HHS and VAS pain scores were 77.5 and 2.23, respectively. In group 2, oteoarthritis and ectopic ossification were observed in 4 and 1 cases, respectively. CONCLUSION: No differences were observed in the clinical outcomes of patients with acetabular fracture or hip fracture-dislocation when treated with or without arthroscopic surgery before open reduction and fixation. However, arthroscopy is thought to be useful for evaluating the joint cartilage surface and fracture fragments more accurately.

Although surgical techniques for treating acetabular fracture are evolving, the use of periacetabular screws is common, and their placement in acetabular surgery is still technically demanding. For instance, intraarticular screw perforation is a serious complication that may occur during surgical treatment of an acetabular fracture. Here, we describe the case of a 50-year-old female who experienced an intraarticular screw perforation after surgical treatment of a posterior acetabular wall fracture. Removal of the perforated screw was performed arthroscopically based on its ability to offer minimally invasive access to the hip joint. One year after removal of the screw, no radiological signs of osteoarthritic changes were observed. The patient regained normal ambulation without limitations to range of motion or hip pain. To our knowledge, this is the first report on the use of arthroscopy to treat intraarticular screw perforation after surgical treatment of an acetabular fracture.

Objective: To compare the effectiveness between modified ilioinguinal approach combined with Kocher-Langenbeck (K-L) approach and Stoppa approach combined with K-L approach for the treatment of complicated acetabular fractures. Methods: Between May 2011 and May 2016, Sixty-two patients with complicated acetabular fractures were treated with operation via combined anterior and posterior approaches. Thirty-four cases (group A) were treated with modified ilioinguinal approach combined with K-L approach, and 28 cases (group B) were treated with Stoppa approach combined with K-L approach. There was no significant difference in gender, age, injury causes, the type of fracture, time from injury to operation, and associated injury between 2 groups ( P>0.05). The operation time, intraoperative blood loss, and hospitalization time were recorded. X-ray film was performed to evaluate the fracture reduction according to the Matta reduction criteria and observe the fracture healing, osteoarthritis, and heterotopic ossification. Clinical results were evaluated according to the grading system of modified d'Aubigne and Postel. Results: There was no significant difference in operation time, intraoperative blood loss, and hospitalization time between 2 groups ( P>0.05). Postoperative incision fat liquefaction occurred in 2 cases in group A and group B respectively, and deep vein thrombosis of lower extremity occurred in 1 case in group A. No iatrogenic injury was found in 2 groups. Fifty-six patients were followed up after operation. Thirty patients in group A were followed up 12-48 months (mean, 31.8 months). Twenty-six patients in group B were followed up 12-46 months (mean, 30.2 months). At 12 months after operation, according to the grading system of modified d'Aubigne and Postel, the hip function was rated as excellent in 9 cases, good in 16 cases, fair in 3 cases, and poor in 2 cases, with the excellent and good rate of 83.3% in group A; the hip function was rated as excellent in 7 cases, good in 14 cases, fair in 2 cases, and poor in 3 cases, with the excellent and good rate of 80.8% in group B. There was no significant difference in the hip function between 2 groups ( Z=0.353, P=0.724). The X-ray films showed that there were 23 cases of anatomical reduction, 6 cases of satisfactory reduction, and 1 case of unsatisfactory reduction in group A, and 20 cases, 5 cases, and 1 case in group B, respectively. There was no significant difference in the results of fracture reduction between 2 groups ( Z=0.011, P=0.991). Fracture healing was observed in both groups. There was no significant difference in fracture healing time between 2 groups ( t=0.775, P=0.106). During follow-up, 5 cases of osteoarthritis changes, 2 cases of heterotopic ossification, and 2 cases of avascular necrosis of femoral head occurred in group A, and 4 cases, 2 cases, and 1 case in group B, respectively. The difference between 2 groups was not significant ( P>0.05). Conclusion: According to the location and type of fracture, making a choice between the modified anterior approach and Stoppa approach, and then combined with K-L approach for treatment of complicated acetabular fracture, can obtain satisfactory effectiveness.
