RESUMO
BACKGROUND: Fragility fractures without significant trauma of the pelvic ring in older patients were often treated conservatively. An alternative treatment is surgery involving percutaneous screw fixation to stabilize the posterior pelvic ring. This surgical treatment enables patients to be mobilized quickly and complications associated with bedrest and temporary immobility are reduced. However, the functional outcome following surgery and quality of life of the patients have not yet been investigated. Here, we present a comprehensive study addressing the long-term well-being and the quality of life of patients with fragility pelvic ring fractures after surgical treatment. METHODS: Between 2011-2019, 215 geriatric patients with pelvic ring fractures were surgically treated at the university hospital in Göttingen (Germany). Of these, 94 patients had fragility fractures for which complete sets of computer tomography (CT) and radiological images were available. Fractures were classified according to Tile and according to the FFP classification of Rommens and Hofmann. The functional outcome of surgical treatment was evaluated using the Majeed pelvic score and the Short Form Health Survey-36 (SF-36). RESULTS: Thirty five tile type C and 48 type B classified patients were included in the study. After surgery eighty-three patients scored in average 85.92 points (± 23.39) of a maximum of 100 points using the Majeed score questionnaire and a mean of 1.60 points on the numerical rating scale ranging between 0 and 10 points where 0 points refers to "no pain" and 10 means "strongest pain". Also, the SF-36 survey shows that surgical treatment positively effects patients with respect to their general health status and by restoring vitality, reducing bodily pain and an increase of their general mental health. CONCLUSIONS: Patients who received a percutaneous screw fixation of fragility fractures of the posterior pelvic ring reported an overall positive outcome concerning their long-term well-being. In particular, older patients appear to benefit from surgical treatment.

Lateral compression type 1 (LC1) fractures are the commonest pelvic ring injury. However, they represent a heterogenous spectrum of injury mechanisms and fracture patterns, resulting in a lack of strong evidence for a universally agreed treatment algorithm. Although consensus exists that LC1 fractures have a preserved posterior ligamentous complex and are vertically stable, controversy persists around defining internal rotational instability. As such, treatment strategies extend from routine non-operative management through to dynamic imaging such as examination under anaesthetic (EUA) or stress radiographs to guide fixation algorithm. Multiple protocols sit between these two, all with slightly different thresholds for advocating surgery or otherwise, exemplifying a broad lack of consensus that is not seen for other, more severe, grades of pelvic ring injury. In the following review we discuss the evolving concepts of pelvic ring instability and management, starting from a historical perspective, through to current trends and controversies in LC1 fracture treatment. Emerging directions for research and emerging pharmacological and surgical treatments/technologies are also considered and expert commentary from 3 leading centres provided. The distinction is made between LC1 fracture arising from high-energy trauma and those following low-energy falls from standing height (so-called fragility fractures of the pelvis-FFP), since these two patient groups have different functional requirements and medical vulnerabilities. Issues pertaining to FFP are considered separately.

BACKGROUND: Prevention and detection of thromboembolism with pelvic and acetabular fractures remains controversial. The aim of this study was to evaluate a protocol using LMWH prophylaxis and duplex screening both pre-operatively (if there is a delay > 72 h to surgery) and post-operatively at day 5-7. We assessed the incidence of thromboembolism and associated risk factors. METHODS: A total of 255 consecutive patients who underwent pelvic and/or acetabular reconstruction in a major trauma and tertiary referral centre between January 2013 and December 2015 were studied. Forty-three patients were excluded due to non-adherence to protocol leaving 212 patients included in the study. RESULTS: Patients were of mean age 49 years (15-94) and mean ISS 24.5 (4-66). Pre-operative screening detected two patients with asymptomatic above-knee DVT who then underwent pre-operative IVC filter insertion. Post-operative screening detected seven patients (3%) with lower limb DVTs (3 proximal and 4 below knee). The three patients with proximal DVTs were fully anticoagulated and did not develop symptomatic PE. Six patients (2.8%) developed post-operative PE, four of which were symptomatic and confirmed by CT angiography. Seven patients (3%) died in the post-operative period due to non-VTE-related causes. The overall rate of VTE was 6%, including DVT 4% and PE 2.8%. PE was associated with administration of tranexamic acid in ED (p > 0.03) and total amount of blood transfused during admission (p > 0.001). VTE was not associated with age, injury type, ISS, delay to surgery or associated injuries. CONCLUSION: A protocol-based approach to VTE prophylaxis and screening in trauma patients with pelvic and/or acetabular reconstruction resulted in no VTE-related mortality. Pre- and post-operative screening for DVT changed the management in five patients, with none developing PE. Patients requiring more aggressive resuscitation had a higher rate of PE. The VTE rate was lower than previously reported.

INTRODUCTION: The incidence of acetabular fractures in older patients is increasing. The management of these patients is evolving due to the recognition of risks associated with prolonged immobility with conservative treatment. MATERIALS AND METHODS: Consecutive patients undergoing fixation and total hip replacement (THR) for displaced acetabular fractures undergoing single operation with acetabular fixation and THR were identified. Outcomes were assessed using radiographs, clinical notes, Oxford Hip Score and EuroQol-5L. RESULTS: 77 patients were identified with 51 completing outcome scores. Mean age 68 years at time of injury. Mean follow-up 5 (2-12) years, OHS 40, EQ-5D 0.78. Revision surgery performed in 7 patients (9%). DISCUSSION: Acute fixation combined with THR for acetabular fractures in the elderly patient, offers good functional outcomes and a low complication rate in the mid-term.

Percutaneous screw fixation combined with pelvic reduction is a surgical technique used to stabilize fractures of the posterior pelvic ring. This is the standard surgical treatment of unstable posterior pelvic ring injuries. The primary goal of this treatment is an anatomic reduction and stable fixation. This has been shown to reduce pain and improve the patients' long-term well-being. The aim of this analysis was to determine the possible screw lengths and the positioning of the screws in the S1 and S2 sacral segments. A population of 697 pelvises from the Stryker Orthopaedic Modeling and Analytics database were analyzed. The dimensions of the S1 and S2 screw corridors were determined and after assessing for sacral dysmorphism, the correct screw placement was chosen to determine the necessary screw length for surgical treatment. The measurements of the screw lengths show a Gaussian distribution for the analyzed population. The percentage of dysmorphic pelvises for the S1 screw corridor was 31.3% and for the S2 corridor 8%. Average screw length for S1 was 163.8 ± 16.2 mm and for the S2 137.3 ± 9.5 mm. The results show that the S1/S2 axis cannot be used for a trans-sacral screw placement in every patient. The study shows that intraosseous screw corridors are present in 68.7% of the patients in the S1 position and in 92% at the S2 level where an intended implant can be placed fully intraosseous.

PURPOSE: Reduction and percutaneous screw fixation of sacroiliac joint disruptions and sacral fractures are surgical procedures for stabilizing the posterior pelvic ring. It is unknown, however, whether smaller irregularities or the inability to achieve an anatomic reduction of the joint and the posterior pelvic ring affects the functional outcome. Here, the long-term well-being of patients with and without anatomic reduction of the posterior pelvis after sacroiliac joint disruptions is described. METHODS: Between 2011 and 2017, 155 patients with pelvic injuries underwent surgical treatment. Of these, 39 patients with sacroiliac joint disruption were examined by radiological images and computer tomography (CT) diagnostics and classified according to Tile. The functional outcome of the different surgical treatments was assessed using the short form health survey-36 (SF-36) and the Majeed pelvic score. RESULTS: Complete data sets were available for 31 patients, including 14 Tile type C and 17 type B injuries. Of those, 26 patients received an anatomic reduction, 5 patients obtained a shift up to 10 mm (range 5-10 mm). The SF-36 survey showed that the anatomic reduction was significantly better in restoring the patient's well being (vitality, bodily pain, general mental health and emotional well-being). Patients without this treatment reported a decrease in their general health status. CONCLUSIONS: Anatomic reduction was achieved in over 80% of patients in this study. When comparing the long-term well-being of patients with and without anatomic reduction of the posterior pelvis after sacroiliac joint disruptions, the results suggest that anatomical restoration of the joint is beneficial for the patients.

BACKGROUND: A consecutive series of 177 male patients, with high energy pelvic ring injuries, were treated operatively in our institution. The purpose of this study was to evaluate long-term sexual and urological dysfunction in these patients using validated disease specific patient reported outcome measures (PROMs), and identify if sexual and urological dysfunction is detectable from generic outcome scores used in the assessment of pelvic ring injury at a minimum of 10 years follow-up (range 10-22). METHODS: Surviving patients were contacted to complete validated PROMs to examine genitourinary and global functional outcome. Fifty-two male participants, had a mean age of 44-years-old (range,16-69) and ISS of 17 at time of injury. Mean duration follow-up of 15 years. The primary outcome measures were the Sexual Health Inventory for Men (SHIM) and the Modular Questionnaire for Male Lower Urinary Tract Symptoms (MLUTS). Secondary outcomes were the EQ-5D and Short Form 36. Responses were tested for correlation between generic and disease-specific PROMs and analyzed for association with genitourinary injury and age as risk factors of poor outcome. RESULTS: Genitourinary injuries occurred in 7 patients (13%), and ten patients (19%) had documented neurological dysfunction following injury. Satisfactory general functional outcome was reported with EQ-5D-3L VAS score of 71. However, 80% report some level of sexual dysfunction with 37% reporting it as severe. MLUTS mean symptom score was 9 (range, 0 - 26) and bothersomeness score was 21 (range, 0-90). There was poor correlation between urological and sexual dysfunction scores and between the disease specific and generic scores. CONCLUSION: In operatively treated pelvic ring injuries, validated disease specific PROMs, (SHIM and MLUTs) identified a significant impact to both sexual and urological patient health, with 37% reporting severe sexual dysfunction. Longstanding sexual and/or urological dysfunction can be a source of significant psychological impact that this study has shown is not identifiable using generic PROMs; EQ-5D-3L and SF-36. To gain a holistic understanding of the functional outcome of patients following a pelvic injury, urological and sexual dysfunction must not be overlooked.

RESUMO
Osteosynthesis of the acetabulum is complex and requires very careful planning and preoperative preparation. The goal is to achieve anatomical reduction without steps or gaps in the articular surface. If it has not been possible to achieve an optimal reconstruction, one has to consider whether it makes sense to carry out reosteosynthesis or revise the fixation. The risk of infection, heterotopic ossification, avascular necrosis of the femur and cartilage damage is much higher than with the primary procedure. Often, especially in older patients, it may make more sense to achieve fracture union and to implant a total hip prosthesis in due course. In younger patients, every attempt should be made to achieve optimum anatomical reduction and this may mean consideration of reosteosynthesis after careful planning and counselling of the patient. If reosteosynthesis is considered adequate imaging including a postoperative CT is essential as part of the planning. This article looks at the possible solutions for failed osteosynthesis of the acetabulum.
RESUMO
OBJECTIVE: Delayed presentation of complex acetabular fractures isn't uncommon. Surgical treatment of such fractures demand special consideration with respect to surgical approach, reduction techniques, fixation and avoidance of complications. This paper intends to review the literature with regard to the suggested treatment modalities and the reported outcome in late presentations and conclude any recommendations appropriate to the practice in current times. BACKGROUND: Displaced fractures of acetabulum, when remained untreated for more than three weeks, pose significant challenge to fracture reduction due to rapid callus formation. In 1976, Letournel described the "Extended Ilio-Femoral Approach"(EIFA) to provide adequate exposure for effective reduction of such fractures. It offered greater exposure of both anterior and posterior columns through a single window, which allowed more precise and controlled reduction of the complex fractures under vision. But despite early enthusiasm in its practice, there has been a steep decline in its application due to reported higher risk of complications. Despite the challenges, the accuracy of fracture reduction in complex acetabular fractures with late presentation was found to be superior in EIFA than the reduction that were achieved by other approaches. Hence a debate to find out the utility of this approach for late reconstruction of complex acetabular fractures (in the face of reported risks of complications) is worthwhile especially in younger patients, who are not suitable candidates for an acute hip replacement surgery and who need their native hip to function well at least for a few years, for their professional and personal high demand activities in their active youthful period. METHODS: The articles for review were retrived using Google Scholar for data retrieval as Pubmed didn't yield any meaningful results due to paucity of publication in this subject. There were only very few papers in the English literature since 1979, which focused on this condition and were considered for this review. We have included our experience on using EIFA in late presentations of complex acetabular fractures spanning from 1999 to 2019, an experience over two decades to this report. RESULTS: It was observed that despite delayed presentation, good articular reduction was possible by using EIFA even in complex acetabular fractures. Ultimate functional outcomes were directly related to the accuracy of fracture reduction thus achieved. The risk of heterotrophic ossification in EIFA, though emphasized as significant in the published literature, was found to be least of a problem in our experience. DISCUSSION: Surgical fixation in delayed cases of complex acetabular fractures was found to be challenging. The choice of surgical approach was found to have a great bearing on the accuracy of fracture reduction and long term functional outcome. In complex acetabular fractures, despite delay in presentation, precise reduction of such fractures was found to be possible when operated using EIFA. CONCLUSION: It was concluded that Every effort must be made to reconstruct the displaced fractures of acetabulum, even in the complex types,despite when they present late, provided the fracture fits into the selection criteria described by Letournel and operated using EIFA. This is very much appropriate to younger patients, who are not great candidate for total hip replacement surgery.
RESUMO
The management of both-column fractures of the acetabulum is challenging for the orthopaedic surgeon. Operative treatment is usually recommended in this particular fracture pattern, as residual joint surface displacement has been shown to increase local contact stress, drastically leading to rapid cartilage destruction. In this review, we present an overview of operative steps and surgical technique for both-column acetabular fracture reconstruction. Therefore, we demonstrate how correct understanding of fracture morphology and displacement, preoperative preparation, including choice of approach and patient positioning, reduction strategies, and programmed sequential fixation, starting from superior fracture lines on the anterior acetabular column and ending on the posterior components of this fracture type, may provide satisfactory outcomes in this difficult acetabular fracture pattern.
RESUMO
INTRODUCTION AND AIMS: The use of routine postoperative computerized tomography (CT) scan after acetabular fracture reconstruction remains controversial. CT scan may provide more accurate detail regarding metalwork position, retained intra-articular fragments, and quality of reduction but does expose the patient to additional radiation dosage and incurs increased cost. The aim of this study was to evaluate a protocol of routine postoperative CT scan for all acetabular fractures after surgical fixation and assess the effect this has on patient management. PATIENTS AND METHODS: The perioperative fluoroscopic images and postoperative plain radiographs of 122 patients who underwent surgical stabilization of a displaced acetabular fracture were reviewed and categorized into 3 groups: (1) safe, when there was no suspicion of metalwork malposition or intra-articular fragments; (2) inconclusive, when it was not possible to exclude malposition; or (3) definite malposition or intra-articular penetration of implants. The findings were compared with postoperative CT scans. The quality of reduction of the acetabular fracture was graded on plain radiographs using the Matta criteria and compared with the CT scan using a standardized technique. RESULTS: Fractures that were categorized as safe on plain radiographs were confirmed to have no metalwork malposition on CT scan in 94% of the cases, with the other 6% having insignificant findings that did not require revision surgery. When plain radiographs were inconclusive (n = 17), 4 patients had metalwork malposition documented on CT scan and 2 of these required revision surgery. There was an increased risk of implant malposition with use of spring plates for posterior wall stabilization. There was significant variation between the quality of reduction when assessed with plain radiographs as compared with CT scans (P < 0.001). In 42% of the patients who were thought to have anatomic reduction on plain radiographic assessment, the reduction was either imperfect or poor based on CT assessment. CONCLUSIONS: CT scans were more accurate than plain radiographs in detecting metalwork malposition and in assessing quality of reduction of the acetabular fracture. The use of postoperative CT scans may be restricted to a group of fractures that have inconclusive or definite malpositioning of implants on perioperative or postoperative radiographs, especially with use of spring pates or to those patients in whom quality of reduction needs more accurate assessment for quality assurance or prognostic reasons. LEVEL OF EVIDENCE: Level IV; Diagnostic -Investigating a diagnostic test.

OBJECTIVES: To report the long-term functional outcome of a cohort of patients with operatively treated unstable pelvic fractures using validated patient-reported outcome measures. DESIGN: Long-term observational study using prospective and retrospective data. SETTING: Tertiary referral pelvic trauma center, Bristol, United Kingdom. PATIENTS: Seventy-four polytraumatized patients with operatively treated unstable pelvic ring injuries (50 OTA/AO type B and 24 OTA/AO type C, mean Injury Severity Score 17) treated between 1994 and 2005. INTERVENTION: Sixty-four (86%) patients were treated with internal fixation. The remaining 10 patients (14%) were treated with either combined percutaneous posterior fixation and anterior external fixation or external fixation in isolation. MAIN OUTCOME: Patient-reported functional outcome. MEASUREMENTS: Short Form-36, with UK norm-based comparator scores and EQ-5D-3L. RESULTS: Patients were between 11 and 22 years after injury (mean 15 years). We found no significant association between fracture classification and outcome score, but compared with age- and sex-matched scores for a UK population, differences were statistically significant in 3 of the 8 domains of health: physical function (P = 0.04), bodily pain (P = 0.001), and vitality (P = 0.001). The level of disability remained constant for these patients compared with their patient-reported outcome measure scores reported 8 years previously. CONCLUSION: Patients who sustain an unstable pelvic fracture continue to have significant functional limitations compared with an uninjured population. These changes were not found to be related to age, injury pattern, genitourinary injury, or neurological injury. Functional outcome scores did not change over the 2 long-term time points. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

AIMS: To determine the effectiveness of 'binder-off' plain pelvic radiographs in the assessment of pelvic ring injuries. PATIENTS AND METHODS: All patients requiring operative intervention at our tertiary referral pelvic unit/major trauma centre for high-energy pelvic injuries between April 2012 and December 2014 were retrospectively identified. Pre-operative pelvic imaging with and without pelvic binder was reviewed with respect to fracture pattern and pelvic stability. The frequency with which the imaging without pelvic binder changed the opinion of the pelvic stability and need for operative intervention, when compared with the computed tomography (CT) scans and anteroposterior (AP) radiographs with the binder on, was assessed. RESULTS: Seventy-three percent (71 of 97) of patients had initial imaging with a pelvic binder in situ. Of these, 76% (54 of 71) went on to have 'binder-off' imaging. Seven percent (4 of 54) of patients had unexpected unstable pelvic ring injuries identified on 'binder-off' imaging that were not identified on CT imaging in binder. CONCLUSIONS: Trauma CT imaging of the pelvis with a pelvic binder in place is inadequate at excluding unstable pelvic ring injuries, and, based on the original findings in this paper, we recommend additional plain film 'binder-off' radiographs, when there is any clinical concern.

OBJECTIVES: To determine if the routine use of intraoperative blood cell salvage in acetabular fracture internal fixation reduces the need for allogenic blood transfusion, is cost effective, and whether it is influenced by the acetabular fracture pattern. DESIGN: A retrospective study. SETTING: Tertiary pelvic and acetabular reconstructive center. PATIENTS/PARTICIPANTS: Patients undergoing internal fixation for acetabular fractures. RESULTS: Eighty consecutive patients were reviewed, comprising 26 elementary fracture (EF) and 54 associated fracture (AF) types. The mean volume of autologous blood transfused was 484 mL. The mean volume of 561 mL of autologous blood transfused in patients with AF types was significantly greater than the mean volume of 325 mL transfused in the EF group (P = 0.007). Additional allogenic blood transfusion was required in 5 (19%) patients with EFs and 15 (28%) patients with AFs (P = 0.418). The mean cost of the blood cell salvage and additional blood products in our study was $223 (£135) for all fracture types ($174/£105 for EF and $246/£149 for AF).When treating AF types, the mean cost of using blood cell salvage was $246 (£149) as compared with the mean predicted cost of not using blood cell salvage and transfusing the equivalent of 1.7 units of allogenic blood instead, which was $463 (£281). These distributions are significantly different (P = 0.01). CONCLUSIONS: The use of blood cell salvage for internal fixation surgery for acetabular fracture is cost effective, particularly when treating AF types, and its routine use is advocated to limit the need for allogenic blood transfusion.
