Patient-reported physical functioning and quality of life after pelvic ring injury: A systematic review of the literature

Surgical management and outcomes of pure sacroiliac joint dislocations: A systematic review

Introduction

Sacroiliac joint (SIJ) dislocations, particularly pure SIJ dislocations without associated fractures, represent a rare and complex subset of pelvic ring injuries. Given the intricate pelvic anatomy and the need to achieve both stability and functional recovery, the optimal surgical management for these injuries remains a topic of debate. This systematic review aims to evaluate the various surgical techniques employed in treating this rare and challenging injury and assess associated clinical outcomes and complications.

Materials and methods

A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence. The included studies were analyzed using the Methodological index for non-randomized studies (MINORS) criteria for quality assessment. This paper was registered in the International Prospective Registry of Systematic Reviews (PROSPERO).

Results

The review identified four studies. The surgical techniques varied across studies, with percutaneous fixation, open reduction and internal fixation (ORIF), and combined approaches being the most reported methods. Clinical outcomes generally indicated satisfactory pain relief and functional recovery (Majeed score 57-90), though the rates of complications, including hardware failure (4-17 %) and infection (17-32 %), were notable. The results also highlighted that anatomical reduction and stable fixation are crucial for optimizing outcomes and minimizing complications. However, the heterogeneity of the data, especially the timing of surgery and surgical technique, precluded a formal meta-analysis.

Conclusions

Surgical management of pure SIJ dislocations presents significant challenges due to the complex biomechanics of the pelvic ring. While various surgical techniques have been employed with generally positive outcomes, the lack of high-quality, large-scale studies limits the ability to establish definitive guidelines. Early definitive treatment of these injuries and anatomical reduction of the SIJ are the main factors to improve clinical outcomes and reduce complication rates.

Pain perception, opioid consumption and mobility following lateral compression pelvic ring injuries: a two-year prospective cohort study

PURPOSE

A prospective longitudinal cohort study was performed to gain insight into the course of recovery in terms of pain, opioid consumption, and mobility in patients with a lateral compression (LC) pelvic injury.

METHODS

Adult patients with an LC injury, without any cognitive disorders or limited mobility and who could communicate in Dutch were asked to participate. Pain in terms of NRS (numeric rating scale, range 0-10), opioid use and mobility were recorded at eight time points: at hospital admission, and three days, one week, six weeks, three months, six months, one year and two years after the injury. A sub-analysis was performed for nonoperatively and operatively treated patients.

RESULTS

Ninety-seven patients were included, of which 23 (24%) were treated operatively and 74 (76%) conservatively. Pain at rest and exertion, were highest upon admission (mean NRS of 3.4 (SD = 2.6) and 4.4 (SD = 2.8), respectively) but decreased within six weeks (mean NRS of 0.8 (SD = 1.6) and 2.0 (2.0), respectively). After two years, the mean NRS was 0.5 (SD = 1.6) and 0.9 (SD = 2.1), respectively. Upon admission, 85% were given opioids, however only 11% used opioids after three months and 4% after two years. At three months, 35% were walking using walking aids and 58% were walking independently. After two years, 98% were walking independently.

CONCLUSIONS

Pain rapidly decreased within the first six weeks. Most patients did not need opioids after three months. Furthermore, most patients were walking with walking aids after six weeks. After two years, few patients experienced pain, used opioids or had difficulties walking.

Is patient-reported outcome after treatment of unstable pelvic ring injuries related to pelvic symmetry? A prospective study

PURPOSE

To determine the relation between pelvic symmetry, as measured by the cross-measurement technique, and patient-reported outcome measures (PROMs) in terms of functional status and health-related quality of life.

METHODS

In this prospective cohort study, X and Y measurements were taken according to the cross-measurement technique on AP radiographs of patients who were treated for an unstable pelvic ring injury in a level-1 trauma center. Patients completed PROMs at the time of admission (recalled pre-injury score) and one year following their injury, reporting their functional status with the Short Musculoskeletal Function Assessment (SMFA-NL), specifically the lower extremity dysfunction (LED), problems with daily activities (PDA) and mental and emotional problems (MEP) subscales, and quality of life with EuroQol-5D (EQ-5D). Subgroup analyses were also performed. PROMs were used to analyze the relation between pelvic symmetry and patient-reported outcome, using Spearman's Rank correlation coefficients.

RESULTS

A total of 130 patients (mean age 58 (SD18) years) with an unstable pelvic ring injury were included, of which 95 (73%) sustained type-B injuries and 35 (27%) type-C injuries. Sixty-three (49%) patients were treated operatively. The median pelvic symmetry ratio was 1.01 (IQR: 0.05). Weak or no correlations were found between the pelvic symmetry scores and the outcome measurements (Spearman's correlation coefficients: LED r = 0.09; PDA r = 0.11; MEP r=-0.02; and EQ-5D r=-0.08). Subgroup analyses revealed no correlations.

CONCLUSIONS

No significant relation was found between pelvic symmetry, measured radiologically, and functional status and health-related quality of life, one year following an unstable pelvic ring injury.

The Italian version of the Majeed pelvic score: translation, cross-cultural adaptation and validation

PURPOSE

The assessment of functional outcomes after pelvic ring fracture remains a controversial topic. The Majeed pelvic score (MPS) is the most commonly used pelvic-specific questionnaire in the literature. The aim of this study is translation, cross-cultural adaptation and validation of the Italian version of MPS.

METHODS

The study was articulated in two phases. Phase 1 consisted in translation and cross-cultural adaptation of MPS, from English into Italian. The psychometric properties were tested on 52 Italian patients (Phase 2). Construct validity was assessed by correlation with Short-Form 12 (SF-12). 33 patients repeated the questionnaire after 14 days to assess its reproducibility. All data were subsequently analyzed (descriptive statistics, multitrait analysis, reliability and construct validity assessment).

RESULTS

The questionnaire was clear and easily understood (no missing data). A ceiling effect was detected for all items of the scale. Multitrait analysis showed good results for each outcome measure, except for the item "walking distance" that showed poor item discriminant validity. A significant correlation between the MPS and the physical component summary (PCS) of the SF-12 was found, while there was a weak correlation with the mental component summary (MCS). The questionnaire showed high internal consistency (Cronbach's alpha: 0.91-0.99) and very good test-retest reliability (intraclass correlation coefficients: 0.92-0.96).

CONCLUSIONS

The Italian version of the MPS has demonstrated to be reliable and valid in the evaluation of patients with pelvic ring fractures. There is still however a need for an instrument capable of evaluating the mental component in these types of injuries.

The trajectory of patient-reported outcomes and minimal clinically important differences in isolated and polytraumatic pelvis and acetabular fractures

PURPOSE

Patient-reported minimal clinically important differences (MCID) provide a standard to compare clinical outcomes. The purpose of this study was to calculate the MCID of PROMIS Physical Function (PF), Pain Interference (PI), Anxiety (AX), and Depression (DEP) scores in patients with pelvis and/or acetabular fractures.

METHODS

All patients with operatively treated pelvic and/or acetabular fractures were identified. Patients were categorized as either only pelvis and/or acetabular fractures (PA) or polytrauma (PT). PROMIS PF, PI, AX, and DEP scores were evaluated at 3-month, 6-month, and 12-month intervals. Distribution-based MCID and anchor-based MCID were calculated for the overall cohort, PA, and PT groups.

RESULTS

The overall distribution-based MCIDs were PF (5.19), PI (3.97), AX (4.33), and DEP (4.41). The overall anchor-based MCIDs were PF (7.18), PI (8.03), AX (5.85), DEP (5.00). The percentage of patients achieving MCID for AX was 39.8-54% at 3 months and 32.7-56% at 12 months. The percentage of patients achieving MCID for DEP was 35.7-39.3% at 3 months and 32.1-35.7% at 12 months. The PT group had worse PROMIS PF scores than the PA group at all time points [post-operative, 3-month, 6-month, and 12-month scores, (28.3 (6.3) vs. 26.8 (6.8) P = 0.016), (38.1 (9.2) vs. 35.0 (8.7) P = 0.037), (42.8 (8.2) vs. 39 (9.6) P = 0.015), (46.2 (9.7) vs. 41.2 (9.7) P = 0.011)].

CONCLUSION

An overall MCID for PROMIS PF was 5.19-7.18, PROMIS PI 3.97-8.03, PROMIS AX of 4.33-5.85, and PROMIS DEP of 4.41-5.00. The PT group had worse PROMIS PF at all time points. The percentage of patients achieving MCID for AX and DEP plateaued at 3 months post-operatively.

Late surgical correction after complex unstable pelvic fracture 61 C3 (OTA/AO) of an 18-year-old woman

Surgical fixation of pelvic fractures is often necessary to restore fracture stability and improve patient outcomes. However, early operative management of pelvis fractures is not widely available in many health systems, resulting in conservative treatment approaches. Conservative approaches can lead to uncorrected pelvic deformities, which are challenging to treat and increase the risk of serious complications such as malunion. Treatment of pelvic malunion requires specialized care, access to necessary equipment, and a clearly defined treatment protocol. However, there is a lack of literature describing treatment algorithms for pelvic fracture malunion. This case report aims to incrementally fill this gap in the literature and highlight a logical step-by-step approach for reconstruction of pelvic malunion. This report is a single case of an 18-year-old woman who sustained complex unstable pelvic fracture, indicated for a 3-step reconstruction at a hospital with limited resources but access to computed tomography scan and some specialized pelvis reduction instruments. Postoperative imaging of the pelvis indicated satisfactory reduction and stable fixation of the pelvic reconstruction. After surgery, the patient was able to perform full axial load with no reported pain. This report provides a detailed description of each step of the operative management of a pelvic malunion case with clearly defined sequences, reduction tools, and positioning maneuvers necessary. Demonstrated in this case report, strategic preoperative planning is critical to successfully treating pelvic malunion and improving patient outcomes. This case report provides the necessary information on the management of pelvic reconstruction to inform other surgeons in underserved regions.

The pathophysiology of pelvic ring injuries: a review

Traumatic pelvic ring injuries continue to represent a major challenge due to the high rates of post-injury mortality of around 30-40% in the peer-reviewed literature. The main root cause of potentially preventable mortality relates to the delayed recognition of the extent of retroperitoneal hemorrhage and post-injury coagulopathy. The understanding of the underlying pathophysiology of pelvic trauma is predicated by classification systems for grading of injury mechanism and risk stratification for developing post-injury coagulopathy with subsequent uncontrolled exsanguinating hemorrhage. This review article elaborates on the current understanding of the pathophysiology of severe pelvic trauma with a focus on the underlying mechanisms of retroperitoneal bleeding and associated adverse outcomes.

Unstable pelvic fractures in women: implications on obstetric outcome

PURPOSE

Obstetric outcomes in women following pelvic injuries requiring surgical fixation is not thoroughly known. We aimed to evaluate if radiographic measurements (RMs) can be used to provide information on delivery methods outcome after these injuries, and to evaluate if metal work removal is required prior to delivery.

METHOD

A retrospective study in a level 1 trauma centre of female patients with pelvic fractures treated operatively, aged 16-45 at the time of injury. Participants completed a questionnaire regarding their obstetric history. RM evaluating pelvic symmetry, displacement, and pelvimetry were conducted on postoperative radiographs and CT scans. Patients who gave birth after the injury were divided to two groups according to the delivery method: vaginal delivery (VD) and caesarean section (CS). These two groups RM were compared.

RESULTS

Forty-four patients were included, comparison of the RM of patients who delivered by CS (9) and patients who had only VD (11) showed no significant difference between the groups. Two patients underwent a trial of VD who subsequently underwent urgent CS due to prolonged labour, their RM were below the average and their pelvimetry measurements were above the cut-off for CS recommendation. Eleven patients had uncomplicated VD, all had retained sacroiliac screws at the time of delivery and one patient had an anterior pubic plate.

CONCLUSION

Postoperative RM did not show an effect on delivery method of women after pelvic fracture fixation. A relatively high number of patients who underwent normal vaginal delivery had retained sacroiliac screws. These findings can form the foundation for larger cohort studies.

Outcomes of open pelvic fractures: A case series

Introduction

Albeit rare, open pelvic fractures are life threatening injuries associated with significant morbidity and mortality. Due to their rarity, there is paucity of data and literature on best management practices. An open pelvic fracture is one where there is a connection between the fracture site and either the skin, rectum, vagina, or genitourinary system. They commonly affect young individuals involved in high energy injuries. During resuscitation, prompt recognition and control of sepsis and stabilization of unstable fractures should precede definitive management.

Materials and methods

We conducted a retrospective study of prospectively collected data between 2012 and 2022 for patients managed in two teaching hospitals in Kenya. All patients were followed up for at least 6 months. The Faringer classification was used to classify the soft tissue wounds and the Young and Burgess classification was used to classify the pelvic fractures. We investigated their functional outcomes using their ability to ambulate independently and the Merle d' Aubigne-Postel score.

Results

Eight patients with an average age of 31 years were included. All were referrals. Three (37.5 %) developed sepsis but resolved. Four (50 %) needed a diverting stoma, which included 2 of the 3 patients who had developed sepsis. 5(62.5 %) needed an external fixator as part of definitive management. There were no mortalities. All achieved full independent ambulation; and all our patients achieved an average Merle d' Aubigne-Postel score of 17.

Conclusion

Our study demonstrates that early sepsis control, appropriate fracture fixation and a multidisciplinary approach can yield satisfactory functional outcomes.

Measuring functional outcomes in major trauma: can we do better?

PURPOSE

There is relatively limited large scale, long-term unified evidence to describe how quality of life (QoL) and functional outcomes are affected after polytrauma. The aim of this study is to review validated measures available to assess QoL and functional outcomes and make recommendations on how best to assess patents after major trauma.

METHODS

PubMed and EMBASE databases were interrogated to identify suitable patient-reported outcome measures (PROMs) for use in major trauma, and current practice in their use globally.

RESULTS

Overall, 81 papers met the criteria for inclusion and evaluation. Data from these were synthesised. A full set of validated PROMs tools were identified for patients with polytrauma, as well as critique of current tools available, allowing us to evaluate practice and recommend specific outcome measures for patients following polytrauma, and system changes needed to embed this in routine practice moving forward.

CONCLUSION

To achieve optimal outcomes for patients with polytrauma, we will need to focus on what matters most to them, including their needs (and unmet needs). The use of appropriate PROMs allows evaluation and improvement in the care we can offer. Transformative effects have been noted in cases where they have been used to guide treatment, and if embedded as part of the wider system, it should lead to better overall outcomes. Accordingly, we have made recommendations to this effect. It is time to seize the day, bring these measures even further into our routine practice, and be part of shaping the future.

Functional outcome of unstable pelvic fractures treated in a level III hospital in a developing country: a 10-year prospective observational study

BACKGROUND

Unstable pelvic fractures are severe and life-threatening injuries with high morbi-mortality rates. Management of these fractures is a major challenge in orthopaedic practice in limited resource communities. The aim of this study is to evaluate the functional outcome of unstable pelvic fractures managed in a hospital with limited diagnostic and therapeutic facilities.

METHODOLOGY

This was a hospital-based prospective observational study carried out from 1st of January 2009 to 31st of December 2018 at the Limbe Regional Hospital, a level III health institution in the South-West region of Cameroon.

RESULTS

A total of 68 patients were included in the study. The ages ranged from 18 to 80 years with a mean age of 39 ± 5 years. The average follow-up duration at the latest visit was 36 months (range 3-84 months). There were 59 cases that were evaluated. The overall average Majeed score was fair. Poor outcomes were noted in patients aged 60 years and above, those with co-morbidities, and those managed conservatively.

CONCLUSION

Although the functional outcomes following unstable pelvic fractures have improved with modernised diagnostic and therapeutic modalities, it is not the case in poor resource settings where the lack of these modalities makes the management challenging, consequently affecting the functional outcome.

The effects of pelvic ring injuries on quality of life, physical, and mental health: results of a 2-year prospective cohort study

Purpose

Pelvic ring injuries are known to affect the patients’ daily life in terms of physical functioning and quality of life (QoL). Still, prospective studies on the patient’s perception over the first 2 years of rehabilitation are lacking. Therefore, patients cannot be properly informed about whether or when they will return to their pre-existing level of physical functioning and QoL.

Methods

A prospective longitudinal cohort study was performed over a 4-year period including all consecutive patients above 18 years who sustained a pelvic ring injury in a level 1 trauma center. Validated patient-reported outcome measures (PROMs) were used to assess physical functioning (SMFA) and QoL (EQ-5D) at baseline (recalled pre-injury score), 6 weeks, 3 months, 6 months, 1 year and 2 years after the injury. It was assessed whether patients had fully recovered by comparing follow-up scores to baseline PROMs. Binary logistic regression analysis was used to identify independent predictors for patients who did not fully recover. Most experienced difficulties at 3 months and 1 year were identified by analyzing the highest reported scores on individual items of the SMFA.

Results

A total of 297 patients with a pelvic ring injury were identified of which 189 were eligible for follow-up and 154 (82%) responded. Median SMFA function score at 3 months, 1 and 2 years was 70, 78 and 88, respectively, compared to 96 out of 100 before the injury. Median SMFA bother score was 67, 79 and 88, respectively. Median EQ-5D score at 3 months, 1 and 2 years was 0.61, 0.81 and 0.85, respectively, compared to 1 (maximum achievable) before the injury. After 1 and 2 years of follow-up, 61% and 75% of the patients fully “recovered” in physical functioning and 52% and 71% fully recovered in terms of QoL. Female gender and high-energy trauma were independent predictors for not fully recovering after 1 year. After 3 months of follow-up, 54% of patients reported severe difficulties with recreational activities, whereas after 1 year, most experienced difficulties (31% of patients) concerned heavy house or yard work. Moreover, after 3 months and 1 year, 44% and 27% of patients reported feeling physically disabled.

Conclusion

Pelvic ring injuries have a large impact on the patients’ daily life in the first 2 years of rehabilitation. Directly after the injury, physical functioning and QoL decrease strongly but then gradually improve over a 2-year period with about 75% of patients fully recovering. Female gender and high-energy trauma are shown to be independent predictors for not fully recovering. After 3 months, patients experience difficulties with both the physical and mental effects of the injury which continue to be present after 1 year.

Quantifying Urinary and Sexual Dysfunction After Pelvic Fracture

OBJECTIVES

To quantify the severity of urinary and sexual dysfunction and to evaluate the relationship between urinary and sexual dysfunction, injury, and treatment factors in patients with pelvic fracture.

DESIGN

Prospective cohort study.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

One hundred thirteen patients with surgically treated pelvic fracture (65.5% OTA/AO 61B fractures; 7 open fractures; 74 men).

INTERVENTIONS

Surgical pelvic stabilization.

MAIN OUTCOME MEASURES

The 36-Item Short Form Health Survey and International Consultation Incontinence Questionnaire responses were collected at baseline, 6 months, and 1, 2, and 5 years. Patients were scored on symptoms of voiding and incontinence, and filling (for women), to derive urinary function. Sexual function was scored as a single domain. Both genders reported urinary and sexual bothersome symptoms. Regression analysis was used to isolate the importance of predictive factors on urinary and sexual function, urinary and sexual bother, and their impact on quality of life.

RESULTS

Patients with pelvic fracture have significant urinary and sexual dysfunction, which is sustained or worsens over time. Male urinary function was predicted by Injury Severity Score (P = 0.03) and 61C fracture (odds ratio: 3.23, P = 0.04). Female urinary function was predicted by urinary tract injury at admission (odds ratio: 7.57, P = 0.03). Neurologic injury and anterior fixation were identified as significant predictors for male sexual function and sexual bother, whereas urological injuries were important in predicting female urinary and sexual bother (P < 0.01). Sexual function (P = 0.02) and sexual bother (P < 0.001) were important predictors of overall mental well-being in men.

CONCLUSIONS

Urinary and sexual dysfunction are prevalent and sustained in men and women and do not follow the prolonged slow recovery trajectory seen in physical function. Male urinary and sexual dysfunction was closely tied to neurologic injury, whereas female urinary and sexual dysfunction was predicted by the presence of a urinary tract injury. Urinary and sexual dysfunction were important to overall mental well-being in men.

What is the long-term clinical outcome after fragility fractures of the pelvis? - A CT-based cross-sectional study

BACKGROUND

Recently, Rommens and Hoffman introduced a CT-based classification system for fragility fractures of the pelvis (FFP). Although fracture characteristics have been described, the relationship with clinical outcome is lacking. The purpose of this study was to get insight into the type of treatment and subsequent clinical outcome after all types of FFP.

METHODS

A cross-sectional cohort study was performed including all elderly patients (≥ 65 years) with a CT-diagnosed FFP, between 2007-2019 in two level 1 trauma centers. Data regarding treatment, mortality and clinical outcome was gathered from the electronic patient files. Patients were asked to complete patient-reported outcome measures (PROMs) regarding physical functioning (SMFA) and quality of life (EQ-5D). Additionally, a standardized multidisciplinary treatment algorithm was constructed.

RESULTS

A total of 187 patients were diagnosed with an FFP of whom 117 patients were available for follow-up analysis and 58 patients responded. FFP type I was most common (60%), followed by type II (27%), type III (8%) and type IV (5%). Almost all injuries were treated non-operatively (98%). Mobility at six weeks ranged from 50% (type III) to 80% type II). Mortality at 1 year was respectively 16% (type I and II), 47% (type III) and 13% (type IV). Physical functioning (SMFA function index) ranged from 62 (type III and IV) to 69 (type II) and was significantly decreased (P=<0.001) compared to the age-matched general population. Quality of life was also significantly decreased, ranging from 0.26 (type III) to 0.69 (type IV).

CONCLUSIONS

FFP type I and II are most common. Treatment is mainly non-operative, resulting in good mobility after six weeks, especially for patients with FFP type I and II. Mortality rates at one year were substantial in all patients. Physical functioning and quality of life was about 20-30% decreased compared to the general population.

Does 3D-Assisted Acetabular Fracture Surgery Improve Surgical Outcome and Physical Functioning?-A Systematic Review

Three-dimensional technology is increasingly being used in acetabular fracture treatment. No systematic reviews are available about the added clinical value of 3D-assisted acetabular fracture surgery compared to conventional surgery. Therefore, this study aimed to investigate whether 3D-assisted acetabular fracture surgery compared to conventional surgery improves surgical outcomes in terms of operation time, intraoperative blood loss, intraoperative fluoroscopy usage, complications, and postoperative fracture reduction, and whether it improves physical functioning. Pubmed and Embase databases were searched for articles on 3D technologies in acetabular fracture surgery, published between 2010 and February 2021. The McMaster critical review form was used to assess the methodological quality. Differences between 3D-assisted and conventional surgery were evaluated using the weighted mean and odds ratios. Nineteen studies were included. Three-dimensional-assisted surgery resulted in significantly shorter operation times (162.5 ± 79.0 versus 296.4 ± 56.0 min), less blood loss (697.9 ± 235.7 mL versus 1097.2 ± 415.5 mL), and less fluoroscopy usage (9.3 ± 5.9 versus 22.5 ± 20.4 times). The odds ratios of complications and fracture reduction were 0.5 and 0.4 for functional outcome in favour of 3D-assisted surgery, respectively. Three-dimensional-assisted surgery reduces operation time, intraoperative blood loss, fluoroscopy usage, and complications. Evidence for the improvement of fracture reduction and functional outcomes is limited.

Does 3D-Assisted Operative Treatment of Pelvic Ring Injuries Improve Patient Outcome?-A Systematic Review of the Literature

Background: There has been an exponential growth in the use of advanced technologies for three-dimensional (3D) virtual pre- and intra-operative planning of pelvic ring injury surgery but potential benefits remain unclear. The purpose of this study was to evaluate differences in intra- and post-operative results between 3D and conventional (2D) surgery. Methods: A systematic review was performed including published studies between 1 January 2010 and 22 May 2020 on all available 3D techniques in pelvic ring injury surgery. Studies were assessed for their methodological quality according to the Modified McMaster Critical Review form. Differences in operation time, blood loss, fluoroscopy time, screw malposition rate, fracture reduction and functional outcome between 3D-assisted and conventional (2D) pelvic injury treatment were evaluated and a best-evidence synthesis was performed. Results: Eighteen studies fulfilled the inclusion criteria, evaluating a total of 988 patients. Overall quality was moderate. Regarding intra-operative results of 3D-assisted versus conventional surgery: The weighted mean operation time per screw was 43 min versus 52 min; for overall operation time 126 min versus 141 min; blood loss 275 ± 197 mL versus 549 ± 404 mL; fluoroscopy time 74 s versus 125 s and fluoroscopy frequency 29 ± 4 versus 63 ± 3. In terms of post-operative outcomes of 3D-assisted versus conventional surgery: weighted mean screw malposition rate was 8% versus 18%; quality of fracture reduction measured by the total excellent/good rate by Matta was 86% versus 82% and Majeed excellent/good rate 88% versus 83%. Conclusion: The 3D-assisted surgery technologies seem to have a positive effect on operation time, blood loss, fluoroscopy dose, time and frequency as well as accuracy of screw placement. No improvement in clinical outcome in terms of fracture reduction and functional outcome has been established so far. Due to a wide range of methodological quality and heterogeneity between the included studies, results should be interpreted with caution.

Pelvic Girdle Pain, Hypermobility Spectrum Disorder and Hypermobility-Type Ehlers-Danlos Syndrome: A Narrative Literature Review

Pelvic girdle pain (PGP) refers specifically to musculoskeletal pain localised to the pelvic ring and can be present at its anterior and/or posterior aspects. Causes such as trauma, infection and pregnancy have been well-established, while patients with hypermobile joints are at greater risk of developing PGP. Research exploring this association is limited and of varying quality. In the present study we report on the incidence, pathophysiology, diagnostic and treatment modalities for PGP in patients suffering from Hypermobility Spectrum Disorder (HSD) and Hypermobility-Type Ehlers-Danlos Syndrome (hEDS). Recommendations are made for clinical practice by elaborating on screening, diagnosis and management of such patients to provide a holistic approach to their care. It appears that this cohort of patients are at greater risk particularly of mental health issues. Moreover over, they may require a multidisciplinary approach for their management. Ongoing research is still required to expand our understanding of the relationship between PGP, HSD and hEDS by appropriately diagnosing patients using the latest updated terminologies and by conducting randomised control trials to compare outcomes of interventions using standardised patient reported outcome measures.

Factors affecting quality of life after pelvic fracture

INTRODUCTION

Functional outcome and health-related quality of life (HRQOL) after pelvis fracture is suboptimal; majority of the patients do not return to their preinjury activities. Many researchers reported that late morbidity in pelvis fracture is associated with severity of the fracture, associated trauma, pelvic fracture-related complications and methods of treatment.

MATERIAL AND METHODS

One hundred and twelve patients with pelvis fracture who were treated either conservatively (n = 88) or surgically (n = 24) with a minimum of two years follow up were evaluated clinically and radiologically. The clinical outcome was evaluated using Majeed score and self-reported Short Musculoskeletal Function Assessment (SMFA). Their HRQOL was evaluated using the 36-item Short Form Survey (SF-36) and WHOQOL-BREF questionnaires. The fracture-displacement in the anterior or posterior pelvis ring was measured from the anteroposterior radiograph or inlet/outlet view.

RESULTS

The average Majeed score was 76.65 ± 14.73 (range, 36 to 96). There were 81 patients with good to excellent outcomes and 31 patients with poor to fair outcomes. The average SF-36 Physical Component Summary (PCS) score was 47.71 ± 7.88 (range, 27.3 to 61.5) and SF-36 Mental Component Summary (MCS) was 49.20 ± 9.37 (range, 23.1 to 56.8). The functional level of the general population in the physical and mental domain was achieved in 48.23% and 65.3% of pelvic-fractured patients respectively. General population norms were achieved in 56.3%, 63.4%, 65.2% and 84.8% of patients in WHOQOL-BREF domain one, two, three and four respectively. The patients had significantly worse functional outcome and HRQOL if residual displacement was > 1 cm. Age, sex, associated injuries and injury mechanism were not affecting the HRQOL in patients with acceptable residual displacement of ≤ 1 cm.

CONCLUSION

Pelvic fracture with the residual displacement of ≤ 1 cm in the sacroiliac joint/symphysis pubis result in better functional outcome and HRQOL. Injury mechanism and associated injury have no impact on the HRQOL if the residual displacement is within the acceptable limit.
