Rajnish RK, Elhence A, Srivastava A, Yadav SK, Kantiwal P, Gupta S. Does the pararectus approach have better outcomes and fewer complications than the modified Stoppa approach for the fixation of acetabular fractures in adults: A systematic review and meta-analysis? EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024:10.1007/s00590-024-03885-y. [PMID: 38451336 DOI: 10.1007/s00590-024-03885-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 02/19/2024] [Indexed: 03/08/2024]
Abstract
BACKGROUND The pararectus approach is a minimally invasive surgical approach for anterior acetabulum fracture, with an advantage of the medial window of the modified Stoppa approach (MSA). However, it is unclear whether the pararectus approach is superior to MSA. We aimed this systematic review and meta-analysis to compare the outcomes and complications of pararectus and MSA. METHODS We performed a data search by conducting an electronic search across databases of PubMed, Embase, Scopus, Cinahl, CNKI, and Cochrane Library and included seven comparative studies for analysis. Statistical analysis was performed using the RevMan software 5.4.1. The risk of bias was evaluated using the Cochrane Collaboration's risk of bias tool for RCTs and the MINORS tool for non-RCTs. RESULTS Two randomized control trials (RCTs), one prospective study, and four retrospective studies were included. Meta-analysis revealed a better Matta's reduction quality [OR 1.58, 95% CI 1.06, 2.37; p = 0.03] and radiological outcome [OR 2.18, 95% CI 1.03, 4.60; p = 0.04] in MSA than in pararectus approach. However, the pararectus approach has less intraoperative blood loss [MD - 9.79 (95% CI - 176.75, - 6.83; p = 0.03)] and a shorter hospital stay [MD - 2.61 (95% CI - 5.03, - .18; p = 0.04)] than MSA. Both approaches have failed to show a difference concerning overall complication rates [OR 0.66 (95% CI 0.28, 1.55; p = 0.34)], postoperative infection, DVT, duration of surgery [MD - 15.09 (95% CI - 35.38, 5.20; p = 0.15)], functional outcome, and incision length. CONCLUSION The pararectus approach offers an advantage with lesser operative blood loss and shorter hospital stay, whilst MSA stands out with better reduction quality and radiological outcomes. Nevertheless, both approaches exhibit no difference in complication rates, duration of surgery, incision length, and functional outcome. Hence, the pararectus approach can be considered an alternative to MSA; however, the existing literature fails to demonstrate a distinct advantage over MSA.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:549-560. [PMID: 37646876 DOI: 10.1007/s00590-023-03700-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 08/17/2023] [Indexed: 09/01/2023]
Abstract
PURPOSE The complex anatomy of acetabular fracture needs a surgical approach that can achieve anatomical reduction with fewer complications for the fixation of these fractures. Current literature suggests that both Pararectus (PR) approach and Ilioinguinal (IL) approach can be used for the fixation of these fractures safely. However, superiority of the PR approach over the IL approach is not established. Hence, this meta-analysis aimed to compare the PR versus IL approach. METHODOLOGY A literature search was performed on five databases Medline/PubMed, Scopus Embase, Cinhal, and Cochrane Library, from the inception to January 14, 2023. A qualitative and quantitative analysis was done for the five eligible studies from the literature search. Individual study characteristics data and outcomes were extracted, and Software version 5.4.1 of Review Manager was used for statistical analysis. RESULTS Five articles, one Randomized trial (RCT), and four retrospective articles were included and analyzed in this meta-analysis. PR approach has a shorter surgical time [mean difference (MD) -48.4 with 95% CI -74.49, -22.30; p = 0.0003], less intraoperative blood loss (MD -123.22 with 95% CI -212.28, -34.15; p = 0.007), and smaller surgical incision (MD -9.87 with 95% CI -15.21, -4.52; p = 0.0003) than the IL approach. However, the meta-analysis failed to show a difference between the two surgical approaches concerning the quality of reduction, overall complications, nerve injury, vascular injury, heterotopic ossification, deep vein thrombosis, and pulmonary embolism. CONCLUSION The PR approach has a shorter surgical duration, less blood loss, and a smaller surgical incision than the IL approach. However, both surgical approaches have equivocal results regarding fracture reduction quality, complication rates, and functional outcomes for acetabular fracture fixation. Hence, for acetabular fractures fixation, PR approach can be considered a safe and feasible alternative to the IL approach.

Orthop Surg 2023; 15:2523-2531. [PMID: 37620863 PMCID: PMC10549807 DOI: 10.1111/os.13817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 05/30/2023] [Accepted: 06/10/2023] [Indexed: 08/26/2023] Open
Abstract
OBJECTIVE As conventional plates require repeated pre-bending during surgery with poor matching, this study aimed to explore the design and application of an acetabular integrative anatomical plate (AIAP) via the lateral-rectus approach (LRA) in fresh complex acetabular fractures for the good reduction and fixation. METHODS We designed an AIAP based on the anatomical morphology of the Chinese people. From March 2016 to September 2021, 178 patients with fresh complex acetabular fractures treated with an AIAP via the LRA were retrospectively analyzed. All patients were treated by the LRA under general anesthesia in a supine position. The fragments were well reduced and fixed by AIAPs. The operation time and intraoperative blood loss were recorded. All patients underwent reexamination of pelvic X-rays and CT scans and were followed up for over 1 year postoperatively. The reduction quality of fracture was evaluated according to the Matta criteria. The postoperative functional recovery was evaluated by modified Merle d'Aubigne-Postel scoring system. Statistics were analyzed by SPSS 25.0 (SPSS Inc., Chicago, IL, USA). RESULTS All 178 patients went through the operation successfully. The time from injury to operation ranged from 5 to 21 days (8.7 ± 2.6 days). The operation time ranged from 35 to 150 min (75 ± 29 min). The intraoperative blood loss was from 250 to 1400 ml (440 ± 153 ml). According to the Matta score, the fracture reduction was evaluated as excellent in 131 cases, good in 31 cases, and poor in 16 cases, with an overall excellent and good rate of 91%. Four patients suffered wound fat liquefaction and healed after fresh dressing. All patients were followed up for 1 to 5 years without wound infection. All fractures were healed. At the last follow-up, the modified Merle d'Aubigne-Postel score results were evaluated as excellent in 125 cases, good in 26 cases, and fair in 27 cases, with an overall excellent and good rate of 84.8%. Postoperative complications included six cases of traumatic arthritis of the hips and two cases of femoral head necrosis. CONCLUSION The LRA with an AIAP can help expose, reduce, and fix anterior and posterior columns as well as the quadrilateral area of the acetabulum, which is capable of improving the reduction quality of complex acetabular fractures and shortening surgical time and blood loss, thus reaching a good clinical efficacy.

Abstract
OBJECTIVE The pararectus approach was rediscovered several years ago for pelvic surgery and described as an alternative approach especially for the treatment of acetabular fractures of the anterior column involving the quadrilateral plate. INDICATIONS For optimal visualization of acetabular fractures involving the quadrilateral plate, fractures of the anterior wall and anterior column, anterior column/posterior hemitransverse fractures, and fractures with central impression of dome fragments, the pararectus approach has proven to be a useful access. CONTRAINDICATIONS The pararectus approach is not used for posterior column fractures, posterior wall fractures, combined posterior wall and posterior column fractures, transverse fractures with displaced posterior column or in combination with posterior wall fractures, and T‑fractures with displaced posterior column or in combination with posterior wall fractures. SURGICAL TECHNIQUE The entire pelvic ring, including the quadrilateral plate, can be accessed via the pararectus approach. The choice of the correct surgical window depends on the fracture location and the requirements of fracture reduction. POSTOPERATIVE MANAGEMENT In general, partial weight-bearing should be maintained for 6 weeks, although earlier weight-bearing release may be possible if necessary, depending on fracture pattern and osteosynthesis. Particularly in geriatric patients, partial weight-bearing is often not possible, so that early and often relatively uncontrolled full weight-bearing has to be accepted. RESULTS In a comparative gait analysis between patients following surgical stabilization of an isolated unilateral acetabular fracture through the pararectus approach and healthy subjects, sufficient stability and motion function of the pelvis and hip during walking was already evident in the early postoperative phase.

Abstract
OBJECTIVES Review clinical results of the treatment for acetabular fractures using the pararectus approach and analyze surgical variations of the traditional approach. DESIGN Retrospective. SETTING Tertiary referral hospital. PATIENTS 46 patients over 65 years of age who sustained an acetabular fracture and underwent surgery using the pararectus approach. INTERVENTION Fractures were treated using a pararectus approach. Three variations of the original technique were performed: (1) Ligature of the deep iliac circumflex artery and vein, (2) separation of the psoas and iliacus muscles, and (3) isolation of the spermatic cord in men and round ligament in women together with the iliac and epigastric vessels. MAIN OUTCOME MEASUREMENTS Outcomes measures included surgical, demographic, and clinical data, and information related to follow-up. RESULTS Duration of surgery, 125 minutes (95-210). Quality of reduction on postoperative computed tomography (CT) scan; anatomic in 22 patients (47.8%), incomplete in 16 (34.8%), and poor in 8 (17.4%). In patients in whom the hip was preserved (n = 41), functional status was excellent in 15 patients (36.5%), good in 17 (41.4%), fair in 6 (14.7%), and poor in 3 (7.4%), with mean functional score of 16 points (7-18). Seven patients (15.2%) developed posttraumatic osteoarthritis and 4 of these patients underwent total hip replacement. CONCLUSIONS This study reports positive outcomes in fracture reduction and clinical outcomes with low complications in older patients who suffered acetabular fractures and were treated using a pararectus approach. Small variations in the technique, such as those proposed in this study, may help to widen access to the surgical site and simplify the technique. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
The aim of the treatment of acetabular fractures is principally an anatomical reconstruction of the joint surface to avoid posttraumatic arthritis. The increasing number of geriatric patients with acetabular fractures of the anterior column type resulting from simple falls on the side and substantial patient-related inherited comorbidities, represent particular challenges for the surgical approach and osteosynthesis due to the osteoporotic bone quality. Due to the establishment of minimally invasive lateral pelvic accesses to the acetabulum and the adaptation of the osteosynthesis technique and material to these approaches, it appears that even in very old patients with acetabular fractures mobility can be better and more rapidly restored and sequelae caused by immobility can be prevented.

Abstract
PURPOSE This study aims to evaluate the efficacy of single pararectus approach in patients confirmed with acetabular fracture involving anterior and posterior columns. METHODS A total of 58 patients confirmed with acetabular fracture involving anterior and posterior columns and treated at our hospital between January 2015 and January 2020 were retrospectively analyzed. A single pararectus approach was applied for all patients. Routine X-rays were performed at follow-up of one, three, six, 12, and 18 months, and three-dimensional CT scans were added at six and 18 months. Fracture reduction quality was assessed using the Matta score system, and functional assessment used the Modified Merle D'Aubigné and Postel score system. Post-operative complications, including fat liquefaction and deep vein thrombosis, were recorded and analyzed. RESULTS The median operation time was 186 min while the intra-operative blood loss was 421 mL. The rate of good-to-excellent reduction was 94.8%, and the rate of good-to-excellent hip function score reached 93.1%. Seven patients presented with post-operative complications, including three intra-operative small vascular injuries, two peritoneal small perforations, one fat liquefaction, and one deep vein thrombosis. CONCLUSION Using a single pararectus approach is convenient and effective for treating acetabular fracture involving anterior and posterior columns, especially those involving the quadrilateral area.

Abstract
PURPOSE The Pararectus approach has been introduced as an alternative anterior approach to the Stoppa approach in acetabular surgery. There is no evidence which approach should be preferred, especially regarding approach-related complications. Therefore, aim of this registry study was to compare the Pararectus approach to the Stoppa approach regarding complications and quality of reduction. METHODS Patients from the German Pelvic Registry with a surgically treated acetabular fracture, either through the Pararectus approach or the Stoppa approach, were analyzed or compared regarding demographic, clinical and operative parameters. RESULTS In total, 384 patients with an acetabular fracture received a surgical procedure with either the Pararectus approach (n=120) or the Stoppa approach (n=264). There were no differences between the two groups regarding demographic parameters and fracture pattern. The overall complication rate (35.0% vs. 31.4%), the mortality rate (5.0% vs. 3.0%) and the osteosynthesis-associated complication rate (5.8% vs. 4.2%) tended to be higher in the Pararectus group with no statistical significance. There were significantly more anatomical reductions in the Pararectus group (56% vs. 43%; p=0.01). However, operation time was significantly longer in the Pararectus group (255±125 vs. 205±103 minutes; p<0.001). CONCLUSION Despite a longer operation time, the Pararectus approach and the Stoppa approach are equivalently applicable for the treatment of acetabular fractures regarding complication rates and quality of reduction.

Abstract
BACKGROUND The surgical treatment of complex acetabular fractures is one of the most challenging procedures for orthopedic surgeons. The Pararectus approach, as a reasonable alternative to the existing surgical procedures, was performed for the treatment of acetabular fractures involving the anterior column. This study aimed to evaluate outcome using the Pararectus approach for acetabular fractures involving anterior columns. METHODS Thirty-seven with displaced acetabular fractures involving anterior columns were treated between July 2016 and October 2019 using the Pararectus approach. The functional outcomes (using the Merle d Aubigné and Postel scoring system, WOMAC and modified Harris scoring), the quality of surgical reduction (using the Matta criteria), and postoperative complications were assessed during approximately 26 months follow-up period. RESULTS Thirty-seven patients (mean age 53 years, range: 30-71; 28 male) underwent surgery. Mean intraoperative blood loss was 840 ml (rang: 400-2000 ml) and mean operating time was 210 min (rang: 140-500 min). The modified Merle d Aubigné score was excellent and good in 27 cases (73%), fair in 6 cases (16%), and poor in 3 cases (11%). The mean score was 88.5 (range:77-96) for the modified Harris Hip scores, and 22 (range:7-35) for the WOMAC scores after operation. Postoperative functional outcomes were significantly improved compared with preoperative outcomes (P < 0.0001). The quality of reduction was anatomical in 21 cases (57%), satisfactory in 9 cases (24%), and unsatisfactory in 7 cases (19%). At follow-up, four patients developed a DVT, and heterotopic bone formation was observed in one patient. The hip osteoarthritis was not observed. CONCLUSION The Pararectus approach achieved good functional outcomes and anatomical reduction in the treatment of acetabular fractures involving anterior column with minimal access morbidity.

Abstract
PURPOSE This study aimed to report the early experience (radiographic, functional, and complications outcomes) from an Egyptian (North African) level one trauma centre after utilizing the modified Stoppa and the pararectus approaches to manage anterior-associated types of acetabular fractures. PATIENTS AND METHODS Between January 2014 and April 2018, 63 patients (40 males and 23 females) with a mean age of 33 ± 11.5 were included, 45 patients were treated through the modified Stoppa (group A), and 18 through the pararectus approach (group B). RESULTS At a mean follow-up of 32.11 ± 15.36 months (range 12 to 64), 56 patients (43 group A and 13 group B) were evaluated. The post-operative anatomical reduction was achieved in 44 (78.6%) patients. At the last follow-up, Matta radiological outcome grades were excellent and good in 50 (89.2%) patients, fair and poor in six (10.8%). The mean Harris Hip Score (HHS) was 92.6 ± 7.6; the mean modified Merle D'Aubigné (MMD) score was 16.5 ± 1.5. Excellent functional outcome was reported in 42 (75.0%) and 25 (44.6%) patients according to HHS and MMD scores, respectively. There are four (7.1%) intra-operative iatrogenic complications (two in each approach), three (5.3%) vascular injuries (two in group B and one in group A), and one (1.8%) bladder injury in group A. CONCLUSION Employing less-invasive anterior approaches for managing anterior associated types of acetabular fractures proved efficiency and safety. Good to excellent radiological and functional outcomes were achieved, with no significant difference between both approaches.

Comparison of Therapeutic Outcomes of Transabdominal Pararectus Approach and Modified Stoppa Approach in Treating Pelvic and Acetabular Fractures. Indian J Orthop 2022; 56:829-836. [PMID: 35542317 PMCID: PMC9043044 DOI: 10.1007/s43465-021-00585-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Accepted: 11/29/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVE Pelvic and acetabular fractures are common orthopedic diseases, and this research was to investigate the therapeutic effects of pararectus and Stoppa approaches in treating complex pelvic acetabular fractures. METHODS The clinical information of patients with pelvic and acetabular fractures treated surgically in Lu'an Hospital of Chinese medicine, China from January 2016 to April 2020 was analyzed. There were 30 cases each in the transabdominal pararectus approach and modified Stoppa approach groups. The operation time, incision length, blood loss, and postoperative complications of both groups were recorded according to the Merle d'Aubigné-Postel hip score. The recovery of hip function was evaluated 6 months after surgery, and the clinical and therapeutic efficacies of the two groups were compared. RESULTS The patients were followed up for 6-7 months (average, 6.5 months). The average operation time, incision length, and blood loss in the pararectus and Stoppa approach groups were 180 ± 41.105 min, 8.667 ± 1.373 cm, 259.667 ± 382 mL and 202.667 ± 32.793 min, 11.600 ± 1.958 cm, and 353.667 ± 590 mL, respectively. The satisfactory rate of fracture reduction, excellent and good rate of hip function score, and incidence of complications were 28/30, 27/30, 1/30 and 25/30, 25/30, 3/30, respectively. There were significant differences in operation time, incision length, and blood loss between the two groups (p < 0.05). However, there was no significant difference in the excellent and good rate of hip function score, fracture reduction satisfaction, and complication rate between both groups (p > 0.05). CONCLUSIONS The pararectus approach can reveal the better anatomical structure of the pelvis and acetabulum, such as the corona mortis and quadrilateral plate, for conducive fracture reduction and fixation. It can also effectively shorten the length of the incision, reduce operative blood loss, and shorten the operation time. It is a better choice for the clinical treatment of complex pelvic and acetabular fractures.

The acetabular roof reinforcement plate for the treatment of displaced acetabular fractures in the elderly: results in 59 patients. Arch Orthop Trauma Surg 2022; 142:1835-1845. [PMID: 33839910 PMCID: PMC9296387 DOI: 10.1007/s00402-021-03829-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 02/08/2021] [Indexed: 10/26/2022]
Abstract
INTRODUCTION Open reduction and internal fixation is considered the gold standard of treatment for displaced acetabular fractures in younger patients. For elderly patients with osteoporotic bone quality, however, primary total hip arthroplasty (THA) with the advantage of immediate postoperative mobilization might be an option. The purpose of this study was to evaluate the clinical and radiological outcomes of surgical treatment of displaced osteoporotic acetabular fractures using the acetabular roof reinforcement plate (ARRP) combined with THA. MATERIALS AND METHODS Between 2009 and 2019, 84 patients were operated using the ARRP combined with THA. Inclusion criteria were displaced osteoporotic fractures of the acetabulum with or without previous hemi- or total hip arthroplasty, age above 65 years, and pre-injury ability to walk at least with use of a walking frame. Of the 84 patients, 59 could be followed up after 6 months clinically and radiographically. Forty-nine (83%) were primary fractures and 10 (17%) periprosthetic acetabular fractures. RESULTS The mean age was 80.5 years (range 65-98 years). The average time from injury to surgery was 8.5 days (range 1-28). Mean time of surgery was 167 min (range 100-303 min). Immediate postoperative full weight bearing (FWB) was allowed for 51 patients (86%). At the 6-month follow-up, all 59 patients except one showed bony healing and incorporation of the ARRP. One case developed a non-union of the anterior column. No disruption, breakage or loosening of the ARRP was seen. Additional CT scans performed in 18 patients confirmed bony healing. Twenty-six patients (44%) had regained their pre-injury level of mobility. Complications requiring revision surgery occurred in 8 patients. Five of them were suffering from a prosthetic head dislocation, one from infection, one from hematoma and one from a heterotopic ossification. CONCLUSIONS The ARRP has proven to provide sufficient primary stability to allow for immediate FWB in most cases and represents a valuable option for the surgical management of displaced acetabular fractures in this challenging patient group.

[PMID: 32430192 DOI: 10.1016/j.injury.2020.03.049] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 02/26/2020] [Accepted: 03/29/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Surgical treatment of sacral fractures is difficult, both for reduction and stabilization. Traditional surgical reduction and internal fixation require a long duration of operation leading to extra blood loss, extensive tissue damage, and increased risk of post-operation complications. The purpose of this study was to evaluate the feasibility of a minimally invasive technique that could be more effective, more tissue sparing, and lead to less bleeding. We hypothesized that a Pararectus approach for anterior fixation of unstable sacral fractures would be reliable and more advantageous and significantly improve the outcome of sacral fracture repair. METHODS Twelve patients with unstable sacral fractures were recruited and examined by CT scanning. A 3D model of each sacral fracture was reconstructed. The computer-assisted 3D image of the reduced pelvis was 3D printed for surgery simulation and plate pre-bending. All cases were treated operatively with the anterior anatomical reduction and internal fixation via a minimally invasive Pararectus approach. VAS, Matta, and Majeed scores were used to evaluate outcomes of the operation. RESULTS Pre-operations were consistent with the actual surgeries in all cases. The pre-bent plates had an anatomical shape specifically fit to the individual pelvis without further adjustment at the time of surgery, and fracture reductions were significantly improved with little invasive tissue damage. The average operation time was 110 min. The intraoperative blood loss and incision length averaged 695 ml and 6.7 cm, respectively. A high percentage of all cases achieved a diaplasis with an excellent or good score according to the Matta and Majeed standards (83.33% and 91.67%, respectively).All patients achieved clinical healing with an average healing time of 8 weeks. CONCLUSION 3D printing-assisted anterior fixation of unstable sacral fractures via a minimally invasive Pararectus approach is feasible. This new surgical strategy minimizes trauma damage and bleeding and produces satisfactory reduction and therapeutic efficacy.

Abstract
Objective To compare the clinical efficacy of pararectus and ilioinguinal approach in the treatment of acetabular fractures. Methods A retrospective analysis of the clinical data of 60 patients with acetabular fractures treated by the pararectus approach or the ilioinguinal approach from January 2016 to January 2019 was performed to record all data by comparing the length of the surgical incision, the time to expose the fracture and the amount of blood loss during the operation. Patients were routinely followed up at 1, 6 and 12 months postoperatively. The function of the hip joint after the operation (Improved Merle d' Aubigne and Postel scores) and the complications postoperation were recorded. Results There was a significant difference (mean ± SD) in the length of surgical incision [(11.2 ± 1.5) cm vs.(23.8 ± 2.1) cm], and in surgical exposure time [(10.8 ± 1.7) min vs.(19.9 ± 1.9) min] (P < 0.05) between the two approaches; there was no significant difference (mean ± SD) in intraoperative blood loss [(591.8 ± 131.4) mL vs. (614.6 ± 132.7) mL] or in hip function scores at the last follow‐up between the two groups (P > 0.05). In the pararectus approach group, there was one patient (3.3%) with postoperative wound fat liquefaction, and the wound completely improved by secretion culture, enhanced dressing and effective antibiotics, one patient (3.3%) developed lateral femoral cutaneous nerve injury; One case (3.3%) of postoperative myositis ossificans occurred in the ilioinguinal approach group, and there were no obvious symptoms. Conclusions These data suggest that for patients with acetabular fractures, both the pararectus approach and the ilioinguinal approach can achieve satisfactory surgical results, but the former has relatively simple operation and small incision length, which is in line with the modern concept of the minimally invasive pelvis.

Abstract
Background The surgical treatment of acetabular fracture has adverse outcomes and high risk, and minimally invasive method is a good way to reduce complications and improve hip joint function. This study is to investigate the treatment of certain acetabular fractures primarily involving the anterior column and quadrilateral plate using a limited pararectus approach and the anatomical plates. Methods A consecutive cohort of 17 patients with anterior displaced acetabular fractures were managed operatively with a limited approach and the anatomical plates. Ten patients had anterior column fractures, 1 patient had anterior wall fracture, 4 patients had transverse fractures and 2 patients had anterior column with posterior hemi-transverse fractures. The inferior half of the pararectus approach was adopted to open the medial window and to access the anterior column and the quadrilateral plate. The anatomical plates were used for internal fixation. Residual displacements were assessed on the postoperative CT scans using a standardized digital method. The surgical details, hip functional outcomes, and complications were noted. Results All of the patients were operated using the limited pararectus approach and the anatomical plates successfully. The mean operative time and blood loss were 90.9 min and 334.1 ml, respectively. The average postoperative residual gap and step displacement on CT were 2.9 mm and 0.7 mm, respectively. The radiological outcome was estimated according to the Matta score, ten of the cases were graded anatomical, six were graded imperfect, and one was graded poor. Follow up averaged 15 months. Functional outcomes were excellent for nine, good for six, and fair for two. It was noted that one case of peritoneal injury was repaired intraoperatively. Conclusions The limited pararectus approach with the advantages of less trauma, direct exposure to the anterior column and quadrilateral plate. The anatomical plates can fit with the surface of the acetabulum, which saves the time of remodeling plates during operation and facilitate fracture reduction. The combination approach can be a good choice for limited surgery of displaced anterior acetabular fractures especially involving the quadrilateral plate.

Abstract
OBJECTIVES Complex acetabular fractures involving the quadrilateral plate may necessitate infrapectineal buttress plating, which can be performed through the pararectus approach. The aim of this cadaveric study was to identify the anatomical guide points to protect neurovascular structures at the risk of injury during the pararectus approach. METHODS Six fresh frozen cadavers (12 hemipelves) were dissected in this study. Location of the inferior epigastric artery (IEA), obturator nerve and corona mortis (CM) was measured using common anatomic landmarks, namely, anterior superior iliac spine, symphysis pubis (SP), and sacroiliac (SI) joint. RESULTS In the superficial dissection of the abdominal wall, the mean distance between the IEA and anterior superior iliac spine was 106.7 ± 5.2 (range, 99.2-116.4) mm, and the mean distance between IEA and SP was 77.9 ± 3.5 (range, 70.6-82.2) mm. In deep dissection, the mean distance between the SI joint and the SP was 133.1 ± 5.7 (range, 126.0-142.0) mm. The mean distance between the SI joint and ON was 37.3 ± 2.8 (range, 31.0-41.0) mm. The CM was unable to be detected in 2 cadavers, 1 on the right and 1 on the left hemipelves. The mean distance between the CM and SP was 47.7 ± 3.9 (range, 43.0-55.0) mm. CONCLUSIONS A pararectus approach is a useful approach which allows infrapectineal plating in the treatment of complex acetabular fractures; however, the preservation of critical neurovascular structures is essential during dissection. This study is helpful to identify the structures at risk according to commonly used anatomic landmarks. These data might be a necessary guideline for hip and trauma surgeons.

Abstract
Objective To explore the clinical efficacy of pararectus approach combined with 3D printing technique for the surgical treatment of partial acetabular fractures. Methods We retrospectively evaluated 33 (20 males and 13 females) patients with acetabular fractures in the period of June 2017 to December 2018. According to Judet and Letournel classification: 11 cases were of anterior column fracture, 10 cases were of double column fracture, seven fractures were of the anterior column with posterior half transverse, three fractures were of transverse fracture, and two cases were of “T” fracture. For all cases, 3D printing is used to print the acetabular model. Pre‐bent reconstruction plates from the model were placed to fixate fractures via the pararectus approach. Results Thirty‐three patients (mean age 48 years; range, 35–63 years), included 20 men and 13 women, were treated successfully with open reduction and internal fixation by the pararectus approach. Surgery duration was 203 min on average (range: 135–245 min), and intra‐operative bleeding was 1030 mL on average (range: 450–1400 mL). All patients were followed‐up for 12–18 months (average,14 months); two patients (6.0%) developed postoperative ossifying myositis, and there are no obvious symptoms at present; one patient (3.0%) developed postoperative wound infection, and the wound completely improved by secretion culture, enhanced dressing, and effective antibiotics; all the acetabular fractures united after 12 to 16 weeks (average,13 weeks). According to the modified Merle d'Aubigne and Postel scoring system to assess the hip function: excellent in 22 cases (66.7%), good in seven cases (21.2%), and fair in four cases (12.1%). Conclusions In the treatment of partial acetabular fractures, the pararectus approach combined with 3D printing technique can achieve effective reduction and fixation, decrease intraoperative hemorrhage, shorten operation time, and the internal fixation position can be properly adjusted during the operation by looking directly at the model.

Abstract
Purpose The aim of this article is to present history, state of the art, and future trends in the treatment of acetabular fractures. Methods Review of recent and historical literature. Results Acetabular fractures are difficult to treat. The first descriptions of this injury already appeared in ancient Greek history, but intensive development started in the second half of the twentieth century after Judet and Letournel’s seminal work. Their classification is still the gold standard today. It is actually a pre-operative planning system and is used to determine the most appropriate surgical approach. The therapy of choice for dislocated fractures is open reduction and internal fixation. Recent modern techniques based on high-tech computerized planning systems and 3D printing have been successfully integrated into orthopaedic trauma practice. Conclusion There is no ideal surgical approach for acetabulum fracture treatment, so new approaches have been developed in recent decades. The best outcome series have shown good or excellent results, between 70 and 80%.

Abstract
BACKGROUND Fractures of the acetabulum are rare injuries. The indication for surgical stabilization depends on the grade of instability and dislocation. Exact knowledge of the different possible surgical approaches is essential for the planning of the surgical treatment. Both, knowledge of anatomical structures and possible risks of the different approaches, are important. METHODS Over a period of 15 years, we analyzed all patients with acetabular fractures, treated in our Level I Trauma Center with special interest in surgical and approach-related complications. Based on our complication rates, we describe the used different surgical approaches and the accessible anatomical structures respectively. Finally, we focus on strategies to reduce the risk of approach-related complications in acetabular surgery. RESULTS Between January 2003 and December 2017, 523 patients with an acetabular fracture were treated in our Tertiary Referral Hospital. Of these, 101 patients had at least one complication, resulting in an overall complication rate of 19.3%. 296 patients underwent surgical treatment of the acetabular fracture, while 227 patients were treated non-operatively. Surgically treated patients had a significantly higher complication rate of 21.2% (63/296) compared to conservatively treated patients with a complication rate of 16.7% (38/227). Neurovascular and thromboembolic adverse events were the most often complications. CONCLUSIONS Patients with acetabular fractures are at a high risk for different kind of complications. The most common risks are neuro-vascular and thromboembolic incidents. The risk of getting a complication is increased in surgically treated patients, therefore both the indication for surgical treatment and the surgical approach should be carried out carefully, including individual patient parameters and fracture types as well as the surgeons expertise.

Abstract
OBJECTIVE The goal of this survey was to determine the current surgeon-preferred anterior surgical approach for the treatment of acetabular fractures in North America. DESIGN Web-based survey; PARTICIPANTS:: Orthopaedic Trauma Association (OTA) members. METHODS Active members of the OTA were solicited to participate in an OTA-sponsored survey asking for their preferred standard anterior surgical approach to the acetabulum, along with some general demographic data. The approach choices were: the classic ilioinguinal as described by Letournel, a modified ilioinguinal, the modified Stoppa (Anterior Intrapelvic) with or without a lateral window, the pararectus, and an alternative to be specified by the survey taker. RESULTS Of the 675 total active OTA membership, 214 (32%) satisfactorily completed the survey. Of the 214 active members, only 32 (15%) prefer the classic ilioinguinal approach and 60 (28%) prefer some type of modified ilioinguinal approach. More than half of the active member respondents (121; 56.5%) prefer the modified Stoppa approach. Statistical analysis of the respondents' demographic data revealed only years in practice to be significantly different among treatment options (P < 0.01) with those with the least time in practice preferring the modified Stoppa. CONCLUSIONS It seems that the modified Stoppa has become the preferred anterior acetabular fracture surgical approach in North America, being especially favored by those more recently in practice. The exact reasons for this change cannot be determined from this survey and are most likely multifactorial. However, training experience may play an important role.

Abstract
OBJECTIVES To evaluate radiological fracture reduction and clinical results using the pararectus approach in complex acetabular fractures involving the anterior column. DESIGN Retrospective database analysis of prospectively collected data. SETTING Level 1 trauma center. PATIENTS/PARTICIPANTS 61 patients (48 male and 13 female) with a median age of 55 (range 17-91) years were included. According to the chosen surgical approach, they were divided into 2 groups. The P-group included 43 patients, among them 32 male and 11 female patients with a median age of 55 (range 17-90) years. Eighteen patients [16 male, 2 female; median age: 53 (range 23-91) years] were treated through the ilioinguinal approach (I-group). INTERVENTION Anterior surgical procedures through the pararectus or the ilioinguinal approach. MAIN OUTCOME MEASURED Reduction results were rated according to the modified Matta criteria using a measurement protocol of hip joint gaps and steps in computed tomography scans. Operation time, complications, and clinical outcomes median one year postoperatively were compared. RESULTS In the pararectus group reduction was anatomical in 21 out of 40 analyzed patients (52.5%), imperfect in 11 patients (27.5%), and poor in 8 patients (20%). The mean joint step reduction was 3.7 mm, and the mean joint gap reduction was 12.1 mm. In the ilioinguinal group reduction was anatomical in 9 out of 18 patients (50%), imperfect in 4 patients (22%), and poor in 5 patients (28%). The mean joint step reduction was 1 mm, and the mean joint gap reduction was 7 mm. Operation time was significantly shorter in the P-group (mean: 49 minutes; P < 0.001). CONCLUSIONS This study indicates that acetabular fracture reduction using the pararectus approach is at least comparable with the ilioinguinal approach independent of patients' age. A relevant advantage of the pararectus approach was seen in a significantly shorter operation time. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
INTRODUCTION Aim of this study was to biomechanically compare two different acetabular cup fixation constructs in terms of fracture fixation for displaced acetabular fractures involving the anterior column with hemitransverse fracture under partial and full weight-bearing conditions. METHODS Two different reinforcement rings designed as cages for primary THA were biomechanically tested in terms of managing a complex acetabular fracture. Single-leg stance cyclic loading was performed to assess fracture gap movement and fragment rotation. Twelve hemi pelvis Sawbones were divided into two groups: primary THA with acetabulum roof reinforcement plate (ARRP) (n = 6) and primary THA with Burch-Schneider reinforcement cage (BSRC) (n = 6). RESULTS During loading under partial weight-bearing (250 N) fracture gap movement tended to be larger in the BSRC group as compared to the ARRP group. Under full weight-bearing conditions, the ARRP showed 60% significantly less motion (p = 0.035) of the os ilium to os ischii gap compared to BSRC. Fracture gap movements between the os ilium and spina iliaca fragments were significantly reduced by 76% (p = 0.048) for ARRP in contrast to BSRC. The ARRP group also demonstrated significantly less movement in the fracture gaps os ischii to quadrilateral plate (62% reduction, p = 0.009) and quadrilateral plate to spina iliaca (87% reduction, p < 0.001). Significantly less rotational movement of the quadrilateral plate to the os ilium was exhibited by the ARRP group (p = 0.015). CONCLUSIONS The presented acetabulum roof-reinforcement plate (ARRP) provides stable conditions at the acetabular component with adequate stabilization of a displaced acetabular fracture.

Abstract
Injuries of the pelvic ring or the acetabulum are either to be found in young patients with high energy trauma mechanisms or in geriatric patients after simple falls with very low impact energy. The indication for surgical stabilization is given by the grade of instability. Exact knowledge of the different possible surgical approaches is essential for the planning of the surgical treatment. Both, knowledge of reachable anatomical structures and possible risks of the different approaches are important. In this review, we summarize the standard surgical approaches to the pelvic ring and to the acetabulum. We describe the reachable anatomical structures for each approach, approach-related pitfalls, and we focus on strategies to reduce approach-related complications.

Abstract
Fracture acetabulum is a grave injury and a challenge for orthopedic surgeons. Anterior and posterior approaches have been described for fixation of acetabulum fractures. The modified Stoppa approach is considered an alternate to anterior approach, which provides access to pelvis from inside the cavity. The purpose of this article is to review the available literature on use of the modified Stoppa approach in acetabulum fractures. The available data suggest that modified Stoppa approach is useful in anterior acetabulum fractures and some posterior acetabulum fractures, especially where buttressing of medial wall is required.

Abstract
Background Pelvic tumors are usually resected through the utilitarian pelvic incision, an extended ilioinguinal/iliofemoral approach. The pararectus approach, an intrapelvic anatomical approach with extraperitoneal access to the pelvis, has been established previously for the treatment of pelvic and acetabular fractures. However, it has not been used to address pelvic tumors. The study aimed at investigating the feasibility of this approach for pelvic tumor surgery and the possibilities of combining this approach with standard approaches to the hip joint. Methods Thirteen patients that underwent pelvic tumor resections were retrospectively reviewed. Tumor resections were performed through the pararectus (n = 10) or extended pararectus approach (n = 3). In six of those cases, the pararectus approach was combined with extrapelvic approaches including the modified Gibson (n = 4), the Kocher-Langenbeck (n = 1), and the trochanteric flip approach (n = 1). The mean follow-up was 32.6 ± 9.1 months. Results In all cases, the tumor resections were carried out according to the preoperative plan. In seven of 13 cases, wide resections were performed; six of 13 cases were planned close resections. Four cases of major complications were observed (vascular injury, deep infection, iliac vein thrombosis, total hip arthroplasty dislocation). Minor complications were observed in two cases. One tumor recurred locally. At the final follow-up, 10 patients were alive, eight of those without evidence of disease. Conclusion The study demonstrated the suitability of the pararectus approach for pelvic tumor resections. The possibility to combine the approach with standard approaches to the hip joint allowed for single-stage reconstructions of the pelvis and the hip joint without sacrificing surgical margins and function. The pararectus approach is a versatile option adding to the established approaches for musculoskeletal tumor surgery of the pelvis.

Abstract
PURPOSE This study aims to examine the clinical efficacy and surgical techniques of the lateral-rectus approach for treatment of acetabular factures in elderly patients. METHODS After appropriate exclusion, 65 elderly patients with an acetabular fracture who was treated through the lateral-rectus approach from January 2011 and October 2016 were selected retrospectively. By analyzing the medical records retrospectively, the patients' characteristics, fracture type, mechanism of injury, comorbid conditions, ASA class, operative time, intra-operative blood loss, and post-operative complications were assessed. Clinical examination radiographs have been taken, align with the Matta evaluation system. Functional outcomes were evaluated using surveys including SF-36, Harris hip score, and modified Merle D'Aubigne-Postel. RESULTS All 65 patients had undergone the single lateral-rectus approach successfully. Surgery duration was 101.23 min on average (45-210), and intra-operative bleeding was 798.46 ml on average (250-1800). According to the Matta radiological evaluation, the quality of reduction evaluated 1 week after surgery was rated as "anatomical" in 41 (63.1%) cases, "imperfect" in 12 (18.5%) cases, and "poor" in 12 (18.5%) cases. The modified Merle D'Aubigne-Postel score performed 18 months after surgery was categorized as excellent in 40 (61.5%) cases, good in 10 (15.4%) cases, and fair in 15 (23.1%) cases. The mean Harris Hip score was similar as present researches, being 87.18. The mean SF-36 score was 69.12 which was considered as normal for the group age 60 and older. Several complications were found, including screw loosening in 10 cases, fat liquefaction of incision in 2 cases, deep vein thrombosis in 2 cases, and temporary weakness of hip adductors in 5 cases. None of the patients had heterotopic ossification. CONCLUSIONS The lateral-rectus approach is a valuable alternative to the ilioinguinal and modified Stoppa approach, being the treatment of acetabular fractures in elderly patients.

Abstract
OBJECTIVES To report the technical aspects, radiographic results, and complications of a modified ilioinguinal approach for the treatment of bicolumnar acetabular fractures, especially involving the quadrilateral plate. DESIGN Retrospective review. SETTING Level I Trauma Center, Wuhan Union Hospital, China. PATIENTS/PARTICIPANTS Data from all acetabular fractures (n = 96) treated surgically were collected between January 2012 and June 2015. According to the exclusion criteria, 22 patients who had undergone a single supra-ilioinguinal approach with a minimum of 1-year follow-up were included in the study. INTERVENTION The supra-ilioinguinal approach was used to treat bicolumnar acetabular fractures by modifying the ilioinguinal approach, using the navel, anterior superior iliac spine, and the symphysis pubis as landmarks. MAIN OUTCOME MEASUREMENTS The surgical exposure and reduction of fractures is expected to become more direct and convenient, with shorter surgical time, less blood loss, and fewer complications. RESULTS Of the 22 consecutive patients, 5 were anterior column with posterior hemi-transverse, 11 were associated both column, 3 were transverse and 3 were T-type patterns. Average length of incision, operative time, and intraoperative blood loss were 10.7 ± 1.1 cm, 182 ± 40 minutes, and 793 ± 228 mL, respectively. Seventeen cases of the reductions were graded excellent; 4, good; and 1, poor. In the last follow-up, the Merle d 'Aubigné scores showed that 14 cases were excellent; 6, good; and 2, poor. Postoperative deep vein thrombosis occurred in 1 patient and lateral femoral cutaneous nerve injury in 3 patients. CONCLUSIONS For the treatment of bicolumnar acetabular fractures, the supra-ilioinguinal approach provides direct visualization and convenient access to the quadrilateral plate, and allows for appropriate reduction and fixation with few complications.

Abstract
Background This study aimed to evaluate outcome following a single lateral rectus abdominis surgical approach for complicated acetabular fractures, involving anterior and posterior columns. Material/Methods From January 2012 to March 2016, 59 patients, including 36 anterior column hemitransverse fractures, 18 two-column fractures, and five T-type complicated acetabular fractures, were treated with a single lateral rectus abdominis approach and fixed by plates and cannulated lag screws. Anterior column fractures were fixed with 3.5 mm reconstruction plates; posterior column fractures were fixed with 6.5 mm cannulated lag screws. The quality of surgical reduction (using the Matta criteria), functional outcome (using the modified Merle d’Aubigné and Postel scoring system), and postoperative complications were assessed with 24-month follow-up. Results Fifty-nine patients (mean age, 45 years; range, 18–64 years) including 39 men and 20 women underwent surgery. Mean intraoperative blood loss was 514.6 ml (range, 150–830 ml) and mean operating time was 86.3 min (range, 42–145 min). Anatomical reduction was good in 40 cases (67.8%), fair in 15 cases (25.4%), and poor in four cases (6.8%). The modified Merle d’Aubigné score was excellent in 39 cases (66.1%), good in 14 cases (23.7%), fair in five cases (8.5%), and poor in one case (1.7%). At follow-up, there were five cases of peritoneal damage, eight cases of obturator nerve dysfunction, and four cases of postoperative traumatic arthritis. Conclusions The single lateral rectus abdominis surgical approach for the treatment of complicated acetabular fractures was minimally invasive with good anatomical exposure and good outcomes.

Abstract
Introduction Aim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort. Method Fifty-two patients (12 female, 40 male) with a median age of 55 (range 18–90) years and displaced acetabular fractures involving the anterior column were surgically treated in a single level I trauma centre between July 2012 and February 2016 using the pararectus approach. Thirty-four patients (8 female and 26 male) with a median age of 58 (range 20–85) years were available for complete clinical follow-up at regular intervals, finally 24 months post-operatively. Functional outcome was evaluated according to modified Merle d’Aubigné score, Lower Extremity Functional Scale, WOMAC, and SF-36. Results Range of time between trauma and surgical treatment was three (range 0–19) days. Operation time was 140 (range 60–240) minutes, and duration of hospital treatment was 19 (range 7–38) days. Functional results in 34 patients available for final follow-up demonstrated 68 points (median; range 39–80) according to the Lower Extremity Functional Scale, 6% according to the WOMAC (mean; SD ± 14.5%), and 69% (mean; SD ± 20.1%) according to the SF-36. The modified Merle d’Aubigné score was excellent in 22 patients, good in eight patients, and fair in four patients. Discussion/conclusion Based on the good to excellent functional mid-term follow-up results of this study, the pararectus approach can be recommended as sufficient alternative single access to address displaced acetabular fractures involving the anterior column, independent of patients’ age.

Abstract
Background Even 50 years after the introduction of the extrapelvic ilioinguinal approach for open reduction and internal fixation of acetabular fractures involving predominantly the anterior column, this approach is still acknowledged as being the so-called gold standard1. The pattern of acetabular fractures has changed within the last 10 to 20 years2,3, with a greater prevalence of quadrilateral plate fractures that is due in part to the increase in elderly trauma. The intrapelvic approach, also called the modified Stoppa approach4-6, was introduced as a less invasive alternative to the extrapelvic ilioinguinal approach, mostly combined with the first window of the ilioinguinal approach. The Pararectus approach also offers intrapelvic surgical access and has demonstrated safe surgical dissection with enhanced exposure and favorable outcome compared with the Stoppa approach7-10. Description The skin incision runs along the lateral border of the rectus abdominis muscle to develop the anterior rectus sheath. The retroperitoneal space lateral to the rectus abdominis muscle is entered and the inferior epigastric vessels and the round ligament in females or the spermatic cord in males are identified. The superior pubic ramus and the iliopectineal eminence are exposed. If the corona mortis vessels (a vascular anastomosis between the obturator vessels and the external iliac artery) are present, they are ligated. The obturator nerve and vessels are exposed. The dissection is then directed posteriorly under retraction of the external iliac vessels with further subperiosteal exposure of the pubic ramus, the quadrilateral plate, and the posterior column. Any nonessential iliolumbar vessels are ligated. Residual displacement is assessed with fluoroscopic views. For reduction of a medially displaced femoral head, longitudinal extremity soft tissue or lateral skeletal traction (optional), with a Schanz pin in the greater trochanter, is used. For disimpaction of acetabular dome fragments and grafting of a supra-acetabular void (optional), a fluoroscopy unit is used to assess reduction and identify the void; in addition, arthroscopy can be used. The scope is introduced through the fracture gap to check for reduction without any water or specific setup. For reduction and fixation of extra-articular components (iliac wing posteriorly and superior pubic ramus anteriorly), the posterior column, and the quadrilateral plate, the fluoroscopy unit is used. The anterior lamina of the rectus sheath is sutured, and a layered closure performed. Alternatives The ilioinguinal or modified Stoppa approach might be used instead. Rationale The Pararectus approach combines the advantages of the ilioinguinal approach and the Stoppa approach. The Pararectus approach facilitates surgical access directly above the hip joint, which is comparable with the access obtained through the second window of the ilioinguinal approach, but without dissection of the inguinal canal. Moreover, the Pararectus approach provides intrapelvic visualization that is at least equivalent to that offered by the Stoppa approach but without losing any direct access to the hip joint.

Abstract
BACKGROUND The feasibility of harvesting a vascularized iliac crest utilizing the Pararectus approach was assessed in cadavers and then this new technique was implemented in a clinical case. METHODS Bilaterally in five cadavers the branches of both external iliac arteries were injected with colored silicone to assess their position to each other and to harvest a bone graft vascularized by the deep circumflex iliac artery (DCIA) through the Pararectus approach. This technique was implemented in a 68-years-old female patient, initially admitted to a level-I-trauma center after sustaining multiple injuries by falling from great height. For definitive treatment of a severely contaminated medially open (Gustilo-Anderson Type 3A) calcaneal luxation fracture (Sanders type IIIBC) in this patient a vascularized iliac crest autograft harvest by the Pararectus approach was used for reconstructive surgery. RESULTS The DCIA and the deep inferior epigastric vessels (DIEV: vascularizing the rectus abdominis muscle and main pedicle of the inferiorly based rectus abdominis myocutaneous flap) are very close on the lateral and medial border of the external iliac artery, respectively. As a consequence, the retrograde dissection of the DIEV towards the DCIA through the Pararectus approach made the dissection of the vascularized iliac crest more amenable, preserving both the lateral femoral cutaneous and the genitofemoral nerves. Four months after the surgery the patient was able to fully weight-bear in orthopedic shoes. Radiographs and CT scans showed correct hind foot alignment and bony integration of the vascularized iliac crest graft into the residual calcaneal body. CONCLUSION The Pararectus approach allowed for secure collection of large vascularized iliac grafts. The presented technique was successful as a salvage procedure in a clinical case with substantial bone loss after an open calcaneal fracture.

Abstract
OBJECTIVES Anatomical acetabular plates the anterior intrapelvic approach (AIP) were recently introduced to fix acetabular fractures through the intrapelvic approach. Therefore, we asked the following: (1) Does the preshaped 3-dimensional suprapectineal plate interfere with or even impair the fracture reduction quality? (2) How often does the AIP approach need to be extended by the first (lateral) window of the ilioinguinal approach? DESIGN Observational case series. SETTING Two Level 1 trauma centers. PATIENTS/PARTICIPANTS Patients with unstable acetabular fractures in 2014. INTERVENTION Fracture fixation with anatomical-preshaped, 3-dimensional suprapectineal plates through the AIP approach ± the first window of the ilioinguinal approach. OUTCOME MEASUREMENTS Fracture reduction results were measured in computed tomography scans and graded according to the Matta quality of reduction. Intraoperative parameters and perioperative complications were recorded. Radiological results (according to Matta) and functional outcome (modified Merle d'Aubigné score) were evaluated at 1-year follow-up. RESULTS Thirty patients (9 women + 21 men; mean age ± SE: 64 ± 8 years) were included. The intrapelvic approach was solely used in 19 cases, and in 11 cases, an additional extension with the first window of the ilioinguinal approach (preferential for 2-column fractures) was performed. The mean operating time was 202 ± 59 minutes; the fluoroscopic time was 66 ± 48 seconds. Fracture gaps and steps in preoperative versus postoperative computed tomography scans were 12.4 ± 9.8 versus 2.0 ± 1.5 and 6.0 ± 5.5 versus 1.3 ± 1.7 mm, respectively. At 13.4 ± 2.9 months follow-up, the Matta grading was excellent in 50%, good in 25%, fair in 11%, and poor in 14% of cases. The modified Merle d'Aubigné score was excellent in 17%, good in 37%, fair in 33%, and poor in 13% of cases. CONCLUSION The AIP approach using approach-specific instruments and an anatomical-preshaped, 3-dimensional suprapectineal plate became the standard procedure in our departments. Radiological and functional early results justify joint preserving surgery in most cases. LEVEL OF EVIDENCE Therapeutic Level IV.

Secure Screw Placement in Management of Acetabular Fractures Using the Suprapectineal Quadrilateral Buttress Plate. BIOMED RESEARCH INTERNATIONAL 2017; 2017:8231301. [PMID: 28698880 PMCID: PMC5494112 DOI: 10.1155/2017/8231301] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/02/2017] [Accepted: 05/21/2017] [Indexed: 11/30/2022]
Abstract
Acetabular fractures involving predominantly the anterior column associated with a disruption of the quadrilateral surface can be treated with instrumentation implementing the stabilization of the quadrilateral surface. The recently introduced suprapectineal quadrilateral buttress plate is specifically designed to prevent secondary medial subluxation of the femoral head, especially in elderly patients with reduced ability for partial weight bearing. Whereas there are guidelines available for safe screw fixation for the anterior and posterior columns, there might be a concern for intra-articular placement of screws placed through the infrapectineal part of the quadrilateral buttress plate. Within this report we analyzed retrospectively screw placement in 30 plates in postoperative CT scans using algorithms for metal artifact reduction. None of the screws of the buttress plate penetrated the hip joint. We describe the placement, length, and spatial orientation of the screws used for fracture fixation and suggest that the use of intraoperative image intensifiers with a combined inlet-obturator view of 30–45° best projects the screws and the hip joint. Preoperative knowledge of approximate screw placement and information for accurate intraoperative imaging may contribute to safe acetabular fracture fixation and may reduce operating time and limit radiation exposure to the patient and the personnel. This trial is registered with KEK-BE: 266/2014.

Abstract
INTRODUCTION The incidence of geriatric acetabular fractures continues to increase due to demographic changes. In the elderly, anterior column fractures are common, and standard approaches are associated with a considerable risk for surgery-associated complications. Therefore, a minimally invasive approach was developed in our department. The aim of this study was to examine early and mid-term results regarding the use of this novel two-incision minimally invasive (TIMI) approach in patients aged over 55 years with acetabular fractures. METHODS From July 2007 to April 2014, 47 patients aged over 55 years were treated via the TIMI approach; these patients were included in the present prospective study. The patients' characteristics, data, and early phase of care were assessed during acute care. A radiological evaluation comprised pre- and postoperative CT scans and x-rays, including Judet views at follow-up. Follow-up examinations were performed after 6 and 24 months and comprised a clinical and radiological examination and an evaluation of hip function (Harris Hip Score) and health-related quality of life (EQ-5D). RESULTS The mean age of the patients was 74±11years, with a gender ratio of 35/12 (m/f). The average operation time was 93±30min, and perioperative blood loss amounted to 858±463ml. In total, five (11%) complications associated with the operative procedure occurred, and revision surgery was necessary in three patients. We observed no wound infections, abdominal wall hernias or cases of heterotopic ossification in our sample. The Harris Hip Score at six months after surgery was 81, and it slightly improved to 84 after 24 months. The mean EQ5D index was 0.91 at six months after surgery and 0.92 at 24 months after surgery. CONCLUSION The TIMI approach represents a valuable alternative to the ilioinguinal and modified Stoppa approach for the treatment of acetabular fractures located in the anterior column, which are often observed in geriatric patients. LEVEL OF EVIDENCE Therapeutic Level II (Prospective cohort study).

Abstract
BACKGROUND Misplaced screw during the internal fixation of acetabular fractures may penetrate the hip joint which might cause chondrolysis and traumatic osteoarthritis in the future. This study aims to acquire the safe path for screw insertion along inferior border of the arcuate line fixation route at acetabular area. METHODS Computed tomography (CT) scans of 98 patients without pelvic trauma were rebuilt for three-dimensional models of pelvis. After depicting the fixation route curve, five cross-sections perpendicularly to the curve were established from the anterior of pelvis to the posterior along inferior border of the arcuate line. The safe screw lengths for section 1 and 5 were measured from the computer models. In section 2, 3 and 4, a line from the screw entry point tangent to the inferior edge of the acetabulum was depicted and the measurements of minimum safe direction of screw insertion were performed then marked with angle θ. RESULTS The safe screw lengths for section 1 and 5 were 22.29 ± 4.41 mm and 32.64 ± 4.70 mm (n = 98). The minimum safe angles of screw insertion for the middle three sections 2, 3, and 4 were 65.38 ± 10.23°, 74.20 ± 10.20°, and 57.88 ± 11.11°(n = 98), respectively. The results for the male group (n = 98) indicated smaller minimum safe angles in these three sections compared with the female (n = 98). CONCLUSIONS Compared to male, the minimum safe angles of screw placement at acetabular area for female should be more away from inferior edge of acetabulum and tilt to the bottom of pelvis along inferior border fixation route in surgical management of acetabular fractures.

Treatment of acetabular fractures in older patients-introduction of a new implant for primary total hip arthroplasty. Arch Orthop Trauma Surg 2017; 137:549-556. [PMID: 28247009 PMCID: PMC5352747 DOI: 10.1007/s00402-017-2649-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND Fractures of the acetabulum in younger patients are commonly treated by open reduction and internal fixation. For elderly patients, stable primary total hip arthroplasty with the advantage of immediate postoperative mobilization might be the adequate treatment. For this purpose, a sufficiently stable fixation of the acetabular component is required. MATERIALS AND METHODS Between August 2009 and 2014, 30 cases were reported in which all patients underwent total hip arthroplasty additionally to a customized implant designed as an antiprotrusion cage. Inclusion criteria were an acetabular fracture with or without a previous hemiarthroplasty, age above 65 years, and pre-injury mobility dependent on a walking frame at the most. The median age was 79.9 years (65-92), and of 30 fractures, 25 were primary acetabular fractures (83%), four periprosthetic acetabular fractures (14%), and one non-union after a failed ORIF (3%). RESULTS The average time from injury to surgery was 9.4 days (3-23) and 295 days for the non-union case. Mean time of surgery was 154.4 min (range 100 to 303). In 21 cases (70%), mobilization with full weight bearing was possible within the first 10 days. Six patients died before the follow-up examination 3 and 6 months after surgery, while 24 patients underwent radiologic examination showing consolidated fractures in bi-plane radiographs. In 9 patients, additional CT scan was performed which confirmed the radiographical results. 13 had regained their pre-injury level of mobility including the non-union case. Only one patient did not regain independent mobility. Four complications were recognized with necessary surgical revision (one prosthetic head dislocation, one pelvic cement leakage, one femoral shaft fracture, and one infected hematoma). CONCLUSION The presented cage provides the possibility of early mobilization with full weight bearing which represents a valuable addition to the treatment spectrum in this challenging patient group.

Abstract
Hip dislocations, most often caused by motor vehicle accidents or similar high-energy trauma, traverse a large subset of distinct injury patterns. Understanding these patterns and their associated injuries allows surgeons to provide optimal care for these patients both in the early and late postinjury periods. Nonoperative care requires surgeons to understand the indications. Surgical care requires the surgeon to understand the benefits and limitations of several surgical approaches. This article presents the current understanding of hip dislocation treatment, focusing on anatomy, injury classifications, nonoperative and operative management, and postinjury care.

Abstract
BACKGROUND As an alternative to the modified Stoppa approach, the Pararectus approach is used clinically for treatment of acetabular fractures involving the anterior column. The current study assessed the surgical exposure and the options for instrumentation using both of these approaches. METHODS Surgical dissections were conducted on five human cadavers (all male, mean age 88 years (82-97)) using the modified Stoppa and the Pararectus approach, with the same skin incision length (10cm). Distal boundaries of the exposed bony surfaces were marked using a chisel. After removal of all soft-tissues, distances from the boundaries in the false and true pelvis were measured with reference to the pelvic brim. The exposed bone was coloured and calibrated digital images of each inner hemipelvis were taken. The amount of exposed surface using both approaches was assessed and represented as a percentage of the total bony surface of each hemipelvis. For instrumentation, a suprapectineal quadrilateral buttress plate was used. Screw lengths were documented, and three-dimensional CT reconstructions were performed to assess screw trajectories qualitatively. Wilcoxon's signed rank test for paired groups was used (level of significance: p<0.05). RESULTS After utilization of the Pararectus approach, the distances from the farthest boundaries of exposed bone towards the pelvic brim were significantly higher in the false but not the true pelvis, compared to the modified Stoppa approach. The percentage (mean±SD) of exposed bone accessible after utilizing the Pararectus approach was 42±8%, compared to 29±6% using the modified Stoppa (p=0.011). In cadavers exposed by the Pararectus approach, screws placed for posterior fixation and as a posterior column screw were longer by factor 1.8 and 2.1, respectively (p<0.05), and screws could be placed more posteromedial towards the posterior inferior iliac spine or in line with the posterior column directed towards the ischial tuberosity. CONCLUSION Compared to the modified Stoppa, the Pararectus approach facilitates a greater surgical access in the false pelvis, provides versatility for fracture fixation in the posterior pelvic ring and allows for the option to extend the approach without a new incision.

Abstract
OBJECTIVES All acetabular fractures are difficult to treat surgically, but there are four types involving two columns that are particularly challenging. The choice of surgical approach is crucial. The purpose of the study was to determine and evaluate the factors influencing the choice of surgical approach for two-column acetabular fractures. We hypothesised that more accurate preoperative planning, sophisticated technical capabilities, and evolution of surgeon experience will result in more consistent use of non-extensile single surgical approaches. We also evaluated the outcomes of surgical treatment and the correlation with the surgical approach used. DESIGN Retrospective cohort study. PATIENTS AND METHODS A total of 156 patients with 157 acetabular fractures involving two columns (Letournel T-types and both-column) treated surgically in a 25-year period (1988-2013) were included in the study. The acetabular fractures in this study were divided into two groups according to the date of surgery: 81 in Group 1 (1998-2002) and 76 in Group 2 (2003-2013). All fractures were classified preoperatively according to the Judet and Letournel classification system and Matta's categorisation of surgical approach. Four surgical approaches were used: single Kocher-Langenbeck (KL), single ilioinguinal (II), combined Kocher-Langenbeck and ilioinguinal (KL+II), and extended iliofemoral (EIF). The efficacy of the surgical approach utilised was assessed using three parameters: anatomical reduction, surgical time and intraoperative complications. RESULTS There was no statistical difference between Group 1 and Group 2 in the distribution of T-type (p=0.424) and both-column (p=0.425) fractures. In Group 2 more acetabular fractures were treated through single non-extensile approaches compared with Group 1 (90.8% vs. 54.3%, p<0.001). Increase in single approach surgery resulted in shorter mean surgical time (p<0.001) and significant increase in anatomical reduction (p=0.039). The frequency of intraoperative complications was not statistically different (p=0.07) between the two groups, but there was a trend to fewer complications in Group 2. CONCLUSIONS The surgical approaches chosen for acetabular fractures that involve two columns (Letournel T-types and both-column) should become more consistent. The results of this study indicate that the majority of such acetabular fractures can be treated successfully through single surgical approaches.

Abstract
PURPOSE The pararectus approach has been validated for managing acetabular fractures. We hypothesised it might be an alternative approach for performing periacetabular osteotomy (PAO). METHODS Using four cadaver specimens, we randomly performed PAO through either the pararectus or a modified Smith-Petersen (SP) approach. We assessed technical feasibility and safety. Furthermore, we controlled fragment mobility using a surgical navigation system and compared mobility between approaches. The navigation system's accuracy was tested by cross-examination with validated preoperative planning software. RESULTS The pararectus approach is technically feasible, allowing for adequate exposure, safe osteotomies and excellent control of structures at risk. Fragment mobility is equal to that achieved through the SP approach. Validation of these measurements yielded a mean difference of less <1 mm without statistical significance. CONCLUSION Experimental data suggests the pararectus approach might be an alternative approach for performing PAO. Clinical validation is necessary to confirm these promising preliminary results.
