Fixation Of Acetabular Fractures Research Articles

Acetabular fractures in geriatric patients: epidemiology, pathomechanism, classification and treatment options.

The incidence of geriatric acetabular fractures has shown a sharp increase in the last decades. The majority of patients are male, which is different to other osteoporotic fractures. The typical pathomechanism generally differs from acetabular fractures in young patients regarding both the direction and the amount of force transmission to the acetabulum via the femoral head. Geriatric fractures very frequently involve anterior structures of the acetabulum, while the posterior wall is less frequently involved. The anterior column and posterior hemitransverse (ACPHT) fracture is the most common fracture type. Superomedial dome impactions (gull sign) are a frequent feature in geriatric acetabular fractures as well. Treatment options include nonoperative treatment, internal fixation and arthoplasty. Nonoperative treatment includes rapid mobilisation and full weighbearing under analgesia and is advisable in non- or minimally displaced fractures without subluxation of the hip joint and without positive gull sign. Open reduction and internal fixation of geriatric acetabular fractures leads to good or excellent results, if anatomic reduction is achieved intraoperatively and loss of reduction does not occur postoperatively. Primary arthroplasty of geriatric acetabular fractures is a treatment option, which does not require anatomic reduction, allows for immediate postoperative full weightbearing and obviates several complications, which are associated with internal fixation. The major issue is the fixation of the acetabular cup in the fractured bone. Primary cups, reinforcement rings or a combination of arthroplasty and internal fixation may be applied depending on the acetabular fracture type.

Delayed Fixation of Acetabular Fractures Affects Functional Outcomes and Health-Related Quality of Life, Not Just Quality of Reduction

Delayed Fixation of Acetabular Fractures Affects Functional Outcomes and Health-Related Quality of Life, Not Just Quality of Reduction

Acetabular Fracture Outcomes and Complications: An International Comparison

Introduction While there have been many technological advances in the treatment of acetabular fractures since the landmark article by Judet and Letournel, the effectiveness of many of these advances have not been definitively determined. Comparing patient outcomes between two countries with differing amounts of technological resources may identify the efficacy of such resources. Methods This study retrospectively compared 489 patients (373 US, 116 Romania) who underwent open reduction and internal fixation (ORIF) for acetabular fracture(s) in a Romanian trauma center and a United States (US) trauma center between February 2011 and August 2018. Results US patients had a higher rate for the following comorbidities: diabetes (p=.0268), obesity (p<.0001), and hypertension (p<.0001). US patients had a significantly shorter pre-op delay (p<.0001). Matta’s criteria for initial quality of reduction did not vary significantly between countries (p=.1101). No significant difference was found in rates of DVT (p=.0722), postoperative infections (p=.2819), sciatic nerve lesions (p=.9999), or loss of reduction (p=.9999). US patients had significantly higher Brooker criteria scores for heterotopic ossification (p<.0001). Conclusions There were no significant differences in outcomes between US and Romanian patients even though US patients received treatment using the latest technology while Romanian patients were treated using substantially fewer resources. Given that technological advances in surgical technique come at a considerable price, it makes sense to build upon this study to gain a more precise understanding of how these advances improve outcomes for patients, and whether or not they are worth the added cost.

Similar Medium-Term Revision Rates Following Acute Total Hip Arthroplasty Versus Open Reduction and Internal Fixation for Acetabular Fractures in the Elderly.

The management of elderly acetabular fractures is complex, with high rates of conversion total hip arthroplasty (THA) after open reduction and internal fixation (ORIF), but potentially higher rates of complications after acute THA. The California Office of Statewide Health Planning and Development database was queried between 2010 and 2017 for all patients aged 60 years or older who sustained a closed, isolated acetabular fracture and underwent ORIF, THA, or a combination. Chi-square tests and Student t tests were used to identify demographic differences between groups. Multivariate regression was used to evaluate predictors of 30-day readmission and 90-day complications. Kaplan-Meier (KM) survival analysis and Cox proportional hazards model were used to estimate the revision surgery-free survival (revision-free survival [RFS]), with revision surgery defined as conversion THA, revision ORIF, or revision THA. A total of 2,184 surgically managed acetabular fractures in elderly patients were identified, with 1,637 (75.0%) undergoing ORIF and 547 (25.0%) undergoing THA with or without ORIF. Median follow-up was 295 days (interquartile range, 13 to 1720 days). 99.4% of revisions following ORIF were for conversion arthroplasty. Unadjusted KM analysis showed no difference in RFS between ORIF and THA (log-rank test P = 0.27). RFS for ORIF patients was 95.1%, 85.8%, 78.3%, and 71.4% at 6, 12, 24 and 60 months, respectively. RFS for THA patients was 91.6%, 88.9%, 87.2%, and 78.8% at 6, 12, 24 and 60 months, respectively. Roughly 50% of revisions occurred within the first year postoperatively (49% for ORIF, 52% for THA). In propensity score-matched analysis, there was no difference between RFS on KM analysis (P = 0.22). No difference was observed in medium-term RFS between acute THA and ORIF for elderly acetabular fractures in California. Revision surgeries for either conversion or revision THA were relatively common in both groups, with roughly half of all revisions occurring within the first year postoperatively. III.

Early Acetabular Fracture Repair Through an Anterior Approach Is Associated With Increased Blood Loss.

To determine whether the timing of acetabular fracture fixation through an anterior approach influences estimated and calculated perioperative blood loss. Retrospective cohort study. Level 1 trauma center from 2013 to 2021. Patients aged ≥18 years treated with acetabular fracture fixation through an anterior-based approach. The primary outcome was calculated blood loss (CBL). Secondary outcomes were estimated blood loss reported by surgeon and anesthesia, and blood transfusion requirements. Comparisons of blood loss were made at discrete postinjury time thresholds (24, 36, and 48 hours) and on a continuous basis. One hundred eight patients were studied. The mean age was 65 years, and 73% of patients were male. Earlier fixation of acetabular fractures resulted in greater CBL and estimated blood loss (surgeon and anesthesia) compared with later fixation when analyzed on a continuum and at specific time points (24, 36, and 48 hours). Mean CBL in patients treated earlier (<48 hours, 2539 ± 1194 mL) was significantly greater than those treated later (≥48 hours, 1625 ± 909 mL; P < 0.001). Fracture repair before 48 hours postinjury was associated with a 3 times greater risk of >2000 mL of CBL ( P = 0.006). This did not result in differences in transfusion rates between groups at 24 hours ( P = 0.518), 36 hours ( P = 1.000), or 48 hours ( P = 0.779). Delaying fixation of acetabular fractures treated through an anterior approach for 48 hours postinjury may significantly reduce perioperative blood loss. Prognostic Level III.

Low-dose CT: A safe and effective imaging modality in post-operative pelvic & acetabular fixation

IntroductionPost-operative pelvic & acetabular fixation patients are conventionally imaged using 3-view radiographs (AP, inlet and outlet). The efficacy of such radiographs is inconsistent due to technical difficulties capturing an adequate view, often necessitating repeat radiographs and therefore increasing radiation exposure. Radiographs can be difficult to interpret, limiting the assessment of fracture reduction and fixation, especially with respect to metalwork positioning around articular surfaces. Traditionally, post-operative pelvic & acetabular fixation patients undergo repeat 3-view radiographs post-operatively, at 6 weeks, followed by at 3, 6, 12, 18 and 24 months. We propose a new pathway, in which patients have one low-dose pelvic CT immediately post-operatively, followed by one radiograph (AP pelvis) at the same time points. MethodsA new pelvic CT protocol was created to provide high quality 3D imaging whilst delivering a 5 times lower radiation dose (compared to normal pelvic CT). Data for all pelvic radiographs and CTs between January 2021 and March 2022 was exported. Using dose area product values, effective radiation dose and attributable lifetime cancer risk were calculated. ResultsThere were 42 patients included in the analysis (age range 15 to 87).The average effective dose for the 3-view pelvic X-rays was 0.6mSv (range 0.2 to 2.8mSv), and 1.1mSv (range 0.5 to 2.2mSv) for the low-dose pelvic CT. Traditional 7 × 3-view post-operative radiographs: 7 × 0.6mSv = 4.2mSv (corresponding to 1 in 11,000 cancer risk) Low dose post-operative CT and 6 × 1-view radiographs: 1.1mSv + (6 × 0.6mSv / 3) = 2.3mSv (corresponding to 1 in 20,000 cancer risk) ConclusionLow-dose CT scanning (in conjunction with 1-view radiographs) is an effective and safe imaging modality in the post-operative assessment of pelvic & acetabular fracture fixation, conferring a lower radiation burden, easier logistics, and higher quality images when compared to the traditional pathway of 3-view radiographs.

Optimizing percutaneous reduction and fixation with guidewire modification in pelvic and acetabular fractures: surgical technique and case series.

Minimally invasive percutaneous screw fixation for pelvic ring and acetabular fractures has become increasingly popular due to its numerous benefits. However, the precise placement of the screw remains a critical challenge, necessitating a modification of the current techniques. This paper introduces a refined technique employing a modified guidewire to enhance the precision and efficiency of percutaneous fixation in pelvic and acetabular fractures. This study details the surgical techniques implemented for correcting guidewire misdirection in percutaneous screw fixation and includes a retrospective analysis of patients treated with this modified approach over a three-year period. In this study, 25 patients with pelvic ring and acetabular fractures underwent percutaneous screw fixation. The cohort, predominantly male (23 out of 25), had an average age of 38years. The majority of injuries were due to traffic accidents (18 out of 25). Types of injuries included pelvic ring (6 cases), acetabular fractures (8 cases), and combined injuries (11 cases). Various screw types, including antegrade and retrograde anterior column screws, retrograde posterior column screws, and lateral compression screws, were used, tailored to each case. Over an average follow-up of 18months, there were no additional procedures or complications, such as neurovascular injury or hardware failure, indicating successful outcomes in all cases. This study introduces a simple yet effective method to address guidewire misdirection during percutaneous fixation for pelvic and acetabular fractures, offering enhanced precision and potentially better patient outcomes. Further research with a larger patient cohort is required for a more comprehensive understanding of its efficacy compared to traditional methods. IV.

Acetabular Fracture Outcomes and Complications: An International Comparison.

Despite the groundbreaking research by Judet and Letournel in the 1960s, the specific equipment, surgical approach, fixation strategy, and post-operative course for treating acetabular fractures have not been standardized. Therefore, this study aimed to compare technological resources, operative procedures, and post-operative complications between patients treated for acetabular fractures in Romania and the United States (U.S.). Between February 2011 and August 2018, a total of 116 Romanian patients and 373 U.S. patients underwent open reduction and internal fixation for acetabular fractures. Data were collected prospectively for Romania and retrospectively for the U.S. The authors used T-tests, Fisher's exact tests, and odds ratios to analyze categorical data while ordinal date were assessed using logistic regression. U.S. patients had higher comorbidity rates for diabetes, obesity, and hypertension. However, the initial quality of reduction, graded with Matta's criteria, was similar between American and Romanian patients. Post-operatively, U.S. patients had significantly higher Brooker criteria scores for heterotopic ossification. Rates of deep vein thrombosis, infections, sciatic nerve lesions, and loss of reduction between the two countries were not significantly different. Given the similar initial reduction quality despite technological differences, the authors suggest that fundamental factors, such as surgeon training and experience, may have a greater impact than the availability of technologically advanced operative resources. Future research focusing on the efficacy of these advanced resources for acetabular fracture fixation could help determine their true impact on patient outcomes and improve the cost-effectiveness of this surgery.

Comparison of patient demographics and patient-specific risk factors for readmissions following open reduction and internal fixation for acetabular fractures.

Acetabular fractures are highly complex injuries often resulting from high-energy trauma. The gold standard treatment for these injuries has become open reduction internal fixation (ORIF). The purpose of this study is to further this understanding and investigate how (1) patient demographics and (2) patient-specific risk factors affect 90-day readmission rates. A retrospective, nationwide query of private insurance database from January 1st, 2010 to October 31st, 2020 was performed using ICD-9, ICD-10, and CPT codes. Patients who underwent acetabular ORIF and were readmitted within 90days following index procedure were included, patients who were not readmitted served as controls. Patients were divided by demographics and specific risk factors associated with readmission. The query yielded a total of 3942 patients. Age and sex were found to be non-significant contributing risk factors to 90-day readmissions. Data also showed that statistically significant comorbidities included arrhythmia, cerebrovascular disease, coagulopathy, fluid and electrolyte abnormalities, and pathologic weight loss. This study illustrated how several patient-specific risk factors may contribute to increased 90-day readmission risk following acetabular ORIF. A heightened awareness of these comorbidities in patients requiring acetabular ORIF is required to improve patient outcomes and minimize rates of readmission. Further investigation is needed to improve patient outcomes, and increase awareness of potential post-operative complications in these higher-risk patient populations.

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?

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. 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. 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. 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.

Revision Surgery Risk After Open Reduction and Internal Fixation Versus Acute Total Hip Arthroplasty in Geriatric Acetabular Fractures: A Nationwide Study.

The aging population has contributed to a rising incidence of acetabular fractures in older patients, yet current evidence guiding surgical treatment is limited by small sample sizes. This study used a nationwide database to investigate outcomes in older patients undergoing open reduction and internal fixation (ORIF) versus acute total hip arthroplasty (THA). The PearlDiver database was queried for patients aged 60 years and older with an acute acetabular fracture who underwent ORIF or acute THA (2010 to 2021). ORIF patients were matched 1:1 to THA patients based on age, sex, US region, insurance plan, and Charlson Comorbidity Index score. Patients with less than 2 years of follow-up were excluded. The primary outcome was revision surgery. Of 120,032 patients with an acetabular fracture, 3,768 (3.1%) underwent surgical treatment: 1,482 (39.3%) THA and 2,286 (60.7%) ORIF. Mean age was 71.0 ± 6.51 years. Mean follow-up duration was 5.2 ± 2.1 years. THA patients were slightly older (72.4 versus 70.2 years), had higher Charlson Comorbidity Index scores (3.3 versus 2.7), and had a higher percentage of female patients (62.5% versus 32.2%). After matching, 962 ORIF and 962 THA patients were included. ORIF patients had longer LOS (10.7 versus 8.1 days). ORIF patients were less likely to experience joint infections and periprosthetic fractures, but more likely to experience transfusions. The overall revision surgery rate within 10 years was 14.8% in the ORIF cohort and 6.2% in the THA cohort. In the ORIF cohort, 13.5% of patients had a delayed conversion to THA. In this large national database, acute with or without internal fixation for geriatric acetabular fractures was associated with lower rates of revision surgery within 10 years when compared with a matched cohort undergoing ORIF. ORIF was associated with increased LOS, increased transfusion risk, and lower risk of joint infection and periprosthetic fracture. III.

Are Orthopaedic Trauma Surgeons Appropriately Compensated for Treating Acetabular Fractures? An Analysis of Operative Times and Relative Value Units.

To evaluate the work relative value units (RVUs) attributed per minute of operative time (wRVU/min) in fixation of acetabular fractures, evaluate surgical factors that influence wRVU/min, and compare wRVU/min with other procedures. Retrospective. Level 1 academic center. Two hundred fifty-one operative acetabular fractures (62 A, B, C) from 2015 to 2021. Work relative value unit per minute of operative time for each acetabular current procedural terminology (CPT) code. Surgical approach, patient positioning, total room time, and surgeon experience were collected. Comparison wRVU/min were collected from the literature. The mean wRVU per surgical minute for each CPT code was (1) CPT 27226 (isolated wall fracture): 0.091 wRVU/min, (2) CPT 27227 (isolated column or transverse fracture): 0.120 wRVU/min, and (3) CPT 27228 (associated fracture types): 0.120 wRVU/min. Of fractures with single approaches, anterior approaches generated the least wRVU/min (0.091 wRVU/min, P = 0.0001). Average nonsurgical room time was 82.1 minutes. Surgeon experience ranged from 3 to 26 years with operative time decreasing as surgeon experience increased ( P = 0.03). As a comparison, the wRVU/min for primary and revision hip arthroplasty have been reported as 0.26 and 0.249 wRVU/min, respectively. The wRVUs allocated per minute of operative time for acetabular fractures is less than half of other reported hip procedures and lowest for isolated wall fractures. There was a significant amount of nonsurgical room time that should be accounted for in compensation models. This information should be used to ensure that orthopaedic trauma surgeons are being appropriately supported for managing these fractures. Economic Level IV.

Measurement of functional acetabular column sizes using a 3D CT model, for guiding percutaneous screw fixation of acetabular fractures using fluoroscopy

Measurement of functional acetabular column sizes using a 3D CT model, for guiding percutaneous screw fixation of acetabular fractures using fluoroscopy

A technique for introducing broad-spectrum topical antibiotics during open reduction and internal fixation of acetabular fractures.

Postoperative surgical site infections remain a significant and prevalent complication after open reduction and internal fixation of acetabular fractures. Local antibiotics have been shown to decrease risk of postoperative infection, although recent evidence is conflicting. We provide a consistent and replicable technique for delivering intraoperative broad-spectrum antibiotics in the form of a putty applied directly to surgical implants. With this technique, systemic levels of those antibiotics remain safe and stable.

Finite element analysis of the use of two new types of internal fixation for acetabular fractures

BackgroundBoth-column fracture is a common type of acetabular fracture and is sometimes accompanied by a comminuted fracture of the quadrilateral area. Such fractures are difficult to anatomically reduce and securely fix. In this study, the authors compared the application value and mechanical properties of the Bespoke 3D-printed titanium alloy plates and Union Plate in acetabular both-column fractures.MethodsA both-column fracture model of the acetabulum was established, and the Bespoke 3D-printed titanium alloy plates, Union Plate and a common reconstruction plate were used for fixation. External loads were applied to the model at different angles, and the effects on the plates and the stress and displacement of the screws were determined.ResultsUnder different states of hip joint activity, the maximum stress experienced by the Bespoke 3D-printed titanium alloy plates and Union Plate was significantly smaller than the maximum stress experienced by the common reconstruction plate. The Bespoke 3D-printed titanium alloy plates experienced the lowest maximum stress under different hip joint motions. There was no statistically significant difference between the maximum displacement of the Bespoke 3D-printed titanium alloy plates and Union Plate and that of the common reconstructed plate.ConclusionsThe design of the Bespoke 3D-printed titanium alloy plates imparts a smaller maximum stress and better mechanical properties when repairing acetabular both-column fractures.

Identifying Reasons for Nonmedical Delays in Fixation of Femur, Pelvis, and Acetabular Fractures at a Level 1 Trauma Center.

To identify reasons for nonmedical delays in femur, pelvis, and acetabular fracture fixation at an institution with a dedicated orthopaedic trauma room (DOTR) and an early appropriate care practice model. Retrospective review of a prospective registry. Urban Level 1 trauma center. Two hundred ninety-four patients undergoing 313 procedures for 226 femur, 63 pelvis, and 42 acetabular fractures. Definitive fixation. Reasons for delays in fixation after hospital day 2. Delays occurred in 12.5% of procedures (39/313), with 7.7% (24/313) having medical delays and 4.8% (15/313) having nonmedical delays. Nonmedical delays were most commonly due to the operating room being at-capacity (n = 6) and nonpelvic trauma specialists taking weekend call (n = 5). Procedures with nonmedical delays were associated with younger age (median difference -16.0 years, 95% confidence interval [CI], -28 to -5.0; P = 0.006), high-energy mechanisms (proportional difference [PD] 58.5%, 95% CI, 37.0-69.7; P < 0.0001), Thursday through Saturday hospital admission (PD 30.3%, 95% CI, 5.0-50.0; P < 0.0001), pelvis/acetabular fractures (PD 51.8%, 95% CI, 26.7-71.0%; P < 0.0001), and external fixation (PD 33.0%, 95% CI, 11.8-57.3; P < 0.0001). Only 4.8% of procedures experienced nonmedical delays using an early appropriate care model and a DOTR. Nonmedical delays were most commonly due to 2 modifiable factors-the DOTR being at-capacity and nonpelvis trauma specialists taking weekend call. Patients with nonmedical delays were more likely to be younger, with pelvis/acetabular fractures, high-energy mechanisms, external fixation, and to be admitted between Thursday and Saturday.

Use of 3D Fluoroscopy to Assist in the Reduction and Fixation of Pelvic and Acetabular Fractures: A Safety and Quality Case Series.

Multidimensional fluoroscopy has been increasingly used in orthopaedic trauma to improve the intraoperative assessment of articular reductions and implant placement. Owing to the complex osteology of the pelvis, cross-sectional imaging is imperative for accurate evaluation of pelvic ring and acetabular injuries both preoperatively and intraoperatively. The continued development of fluoroscopic technology over the past decade has resulted in improved ease of intraoperative multidimensional fluoroscopy use in pelvic and acetabular surgery. This has provided orthopaedic trauma surgeons with a valuable tool to better evaluate reduction and fixation at different stages during operative treatment of these injuries. Specifically, intraoperative 3D fluoroscopy during treatment of acetabulum and pelvis injuries assists with guiding intraoperative decisions, assessing reductions, ensuring implant safety, and confirming appropriate fixation. We outline the useful aspects of this technology during pelvic and acetabular surgery and report its utility with a consecutive case series at a single institution. The added benefits of this technology have improved the ability to effectively manage patients with pelvis and acetabulum injuries.

Total Hip Arthroplasty Following Operative Fixation of Acetabular Fracture: A Contemporary Series

BackgroundTotal hip arthroplasty (THA) is the operation of choice for salvage of post-traumatic arthritis following acetabular fracture. While high failure rates have been reported for these procedures, existing literature reports mainly on historical implant designs and techniques. We aimed to describe implant survivorships, complications, radiographic results, and clinical outcomes of contemporary THA following prior open reduction internal fixation (ORIF) of an acetabular fracture. MethodsWe identified 104 patients undergoing THA following prior ORIF of an acetabular fracture from 2000 to 2015 via our institutional total joint registry. Mean age at THA was 50 years (range, 18 to 79 years), 71% were men, and mean body mass index was 27 (range, 18 to 52). All patients were implanted with uncemented acetabular components, and 89% had uncemented stems. Some hardware from prior fixation was retained in 94% of cases. Mean follow-up was 10 years (range, 2 to 21 years). ResultsThe 10-year survivorships free of any revision and any reoperation were 98% and 97%, respectively. There were 4 revisions: 1 each for psoas tendonitis, dislocation, acetabular aseptic loosening, and periprosthetic joint infection. There were 9 complications that did not lead to reoperation: 5 dislocations, 2 periprosthetic femur fractures, 1 sciatic nerve palsy, and 1 case of symptomatic heterotopic ossification. All unrevised components appeared radiographically well-fixed. Mean Harris Hip Score improved from mean 50 preoperatively to mean 82 at 5 years (P < .001). ConclusionsIn this series of contemporary THAs following prior acetabular fracture ORIF, revision-free survivorship was excellent with only a single case of acetabular aseptic loosening. These results are encouraging and suggest that contemporary implants and techniques have notably improved on historic results. Level of EvidenceTherapeutic, Level IV.
