Laminectomy for acute transverse sacral fractures with compression of the cauda equina: A neurosurgical perspective. World Neurosurg X 2024; 23:100374. [PMID: 38584879 PMCID: PMC10997834 DOI: 10.1016/j.wnsx.2024.100374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 03/28/2024] [Indexed: 04/09/2024] Open
Abstract
Introduction Optimal management of transverse sacral fractures (TSF) remains inconclusive. These injuries may present with neurological deficits including cauda equina syndrome. We present our series of laminectomy for acute TSF with cauda equina compression. Methods This was a retrospective chart review of all patients that underwent sacral laminectomy for treatment of cauda equina compression in acute TSF at our institution between 2007 through 2023. Results A total of 9 patients (5 male and 4 female) underwent sacral laminectomy to decompress the cauda equina in the setting of acute high impact trauma. Surgeries were done early within a mean time of 5.9 days. All but one patient had symptomatic cauda equina syndrome. In one instance surgery was applied due to significant canal stenosis present on imaging in a patient with diminished mental status not allowing proper neurological examination. Torn sacral nerve roots were repaired directly when possible. All patients regained their neurological function related to the sacral cauda equina on follow up. The rate of surgical site infection (SSI) was 33%. Conclusion Acute early sacral laminectomy and nerve root repair as needed was effective in recovering bowel and bladder function in patients after high impact trauma and TSF with cauda equina compression. A high SSI rate may be reduced by delaying surgery past 1 week from trauma, but little data exists at this time for clear recommendations.

Lumbopelvic fixation in the treatment of spinopelvic dissociation: union, complications, and neurologic outcomes of a multicenter case series. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024:10.1007/s00590-024-03928-4. [PMID: 38605242 DOI: 10.1007/s00590-024-03928-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 03/20/2024] [Indexed: 04/13/2024]
Abstract
PURPOSE To review outcomes of spinopelvic dissociation treated with open lumbopelvic fixation. METHODS We reviewed all cases of spinopelvic dissociation treated at three Level-I trauma centers with open lumbopelvic fixation, including those with adjunctive percutaneous fixation. We collected demographic data, associated injuries, pre- and postoperative neurologic status, pre- and postoperative kyphosis, and Roy-Camille classification. Outcomes included presence of union, reoperation rates, and complications involving hardware or wound. RESULTS From an initial cohort of 260 patients with spinopelvic dissociation, forty patients fulfilled inclusion criteria with a median follow-up of 351 days. Ten patients (25%) had a combination of percutaneous iliosacral and open lumbopelvic repair. Average pre- and postoperative kyphosis was 30 degrees and 26 degrees, respectively. Twenty patients (50%) had neurologic deficit preoperatively, and eight (20%) were unknown or unable to be assessed. All patients presenting with bowel or bladder dysfunction (n = 12) underwent laminectomy at time of surgery, with 3 patients (25%) having continued dysfunction at final follow-up. Surgical site infection occurred in four cases (10%) and wound complications in two (5%). All cases (100%) went on to union and five patients (13%) required hardware removal. CONCLUSION Open lumbopelvic fixation resulted in a high union rate in the treatment of spinopelvic dissociation. Approximately 1 in 6 patients had a wound complication, the majority of which were surgical site infections. Bowel and bladder dysfunction at presentation were common with the majority of cases resolving by final follow-up when spinopelvic dissociation had been treated with decompression and stable fixation.

Abstract
At the cornerstone of the pelvis and spine, the sacrum may be fractured in patients of all ages. Sacral fractures range from high-energy injuries, with mortality rates of up to 18%, to low-energy insufficiency fractures. The intricate geometry of the sacrum, the breadth of morphotypes, and the presence of congenital anomalies all can complicate the treatment of these fractures. Agreement on the surgical indications for these injuries is limited. This narrative review aims to update orthopedic surgeons on the clinical evaluation and the non-surgical and surgical management of these fractures.

Evolution of the AO Spine Sacral and Pelvic Classification System: a systematic review. J Neurosurg Spine 2022; 37:914-926. [PMID: 35907199 DOI: 10.3171/2022.5.spine211468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 05/18/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The purpose of this study was to describe the genesis of the AO Spine Sacral and Pelvic Classification System in the context of historical sacral and pelvic grading systems. METHODS A systematic search of MEDLINE, EMBASE, Google Scholar, and Cochrane databases was performed consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify all existing sacral and pelvic fracture classification systems. RESULTS A total of 49 articles were included in this review, comprising 23 pelvic classification systems and 17 sacral grading schemes. The AO Spine Sacral and Pelvic Classification System represents both the evolutionary product of these historical systems and a reinvention of classic concepts in 5 ways. First, the classification introduces fracture types in a graduated order of biomechanical stability while also taking into consideration the neurological status of patients. Second, the traditional belief that Denis central zone III fractures have the highest rate of neurological deficit is not supported because this subgroup often includes a broad spectrum of injuries ranging from a benign sagittally oriented undisplaced fracture to an unstable "U-type" fracture. Third, the 1990 Isler lumbosacral system is adopted in its original format to divide injuries based on their likelihood of affecting posterior pelvic or spinopelvic stability. Fourth, new discrete fracture subtypes are introduced and the importance of bilateral injuries is acknowledged. Last, this is the first integrated sacral and pelvic classification to date. CONCLUSIONS The AO Spine Sacral and Pelvic Classification is a universally applicable system that redefines and reorders historical fracture morphologies into a rational hierarchy. This is the first classification to simultaneously address the biomechanical stability of the posterior pelvic complex and spinopelvic stability, while also taking into consideration neurological status. Further high-quality controlled trials are required prior to the inclusion of this novel classification within a validated scoring system to guide the management of sacral and pelvic injuries.

Abstract
BACKGROUND The stabilization of vertical unstable sacral fractures has been a complex problem that is a challenge to current standard approaches. Here, we attempted to evaluate a modified technique for sacral fractures. METHODS In the modified triangular osteosynthesis technique, we adopted a vertical and transverse fixation with a rod and pedicle screw system to reduce and fix sacral fractures in 28 subjects. The postsurgery effect of this technique was evaluated by physical examination and radiography. RESULTS In the postoperative day 1, the patients were able to move body position passively from the lateral side to supine and exercise their legs by themselves. After a follow up of 20 months, radiological evaluation showed that fracture fragment reduction was excellent in 18 (64%), good (displacement 5-10 mm) in 8 (29%), and fair (displacement 10-15 mm) in 2 (7%) patients. Three patients with a preoperative perineal neurological impairment had a complete recovery after surgical decompression. All patients had achieved bone union of fractures, and no loss of fracture reduction was detected. CONCLUSIONS The modified procedures offered an easier approach to fix vertical unstable sacral fractures, thereby achieving quicker and stable functionality. This suggests an alternative approach to manage unstable sacral fractures. LEVEL OF EVIDENCE 4. CLINICAL RELEVANCE The stabilization of vertical unstable sacral fractures has been a complex problem that is a challenge to current standard approaches. We attempted to introduce a modified technique for sacral fractures.

Abstract
BACKGROUND Spinopelvic dissociation (SPD) is difficult to manage and is associated with high mortality and morbidity, including concomitant orthopaedic polytrauma, spine injuries, pelvic ring disruptions, neurological, soft-tissue, and vascular injuries. The purpose of this study is to evaluate the functional and radiological outcomes; health related quality of life and complication rates of patients with traumatic spinopelvic dissociation underwent bilateral triangular osteosynthesis (TOS). METHODS The study was approved by the medical school's institutional review board (IRB). Prospective data collection of nineteen consecutive cases of traumatic SPD were included in the study from October 2015 to August 2018. Bilateral TOS was performed to manage all patients with SPD. The clinical outcome for fractures was analyzed with Majeed function assessment. Health Related Quality of Life (HRQoL) was assessed with the EQ-6D questionnaire. The reduction quality was evaluated according to Matta criterion. CT scanning was used to verify the fracture union in patients at 24th weeks postoperatively. RESULTS There were 12 women and 7 men with an average age of 47.2±8.4 years (range, 17-62 years). The average follow-up time was 25.2±3.7 months (average, 22-45 months). The most common mechanism of injury was falling (57%). According to Majeed functional scoring, the results were excellent in 12 cases, good in 5 cases and fair in 2 cases. The median EQVAS score was 78.9±8.4. 15 patients (78.9%) turned back to their original occupation. Pain and mood disorders mainly influenced patients' present general health status. According to Matta criterion for fracture reduction, the results were excellent in 14 cases, good in 4 cases and fair in 1 case. Complications were noted as wound healing problems (26%), implant loosening (5%) and iatrogenic nerve injury (5%). CONCLUSION Bilateral TOS demonstrates satisfactory functional and radiological outcomes with low complication rates except infection rate in patients with traumatic spinopelvic dissociation. HRQoL is mainly dominated by pain and mood disorders. 78.9% of the patients turned back to their original occupation. Surgeons should be aware of wound healing problems in case of increased muscle mobilization and degloving injuries.Implant removal is required to improve the lumbopelvic mobility.

Abstract
BACKGROUND The purpose of this study was to determine the neurological outcome after transverse sacral fractures in patients with neurological impairment. METHODS A systematic review of the English, French, German, and Dutch literature was conducted. All study designs, including retrospective cohort studies and case reports, describing transverse sacral fractures were included. Two authors independently extracted the predefined data and scored the neurological impairment according to the Gibbons classification after the trauma and at the time of follow-up. The neurological outcomes were pooled according to the Gibbons classification. RESULTS No randomized controlled trials or prospective case series were found. A total of 139 articles were included, consisting of 81 case reports and 58 retrospective case series involving 521 patients. Regardless of the type of management, neurological recovery of at least 1 Gibbons category was reported in 62% of these patients. A comparison of the neurological outcome of nonoperatively treated patients and surgically treated patients showed similar neurological recovery rates. For the surgically treated patients, fixation of the fracture resulted in a better neurological improvement compared with an isolated decompression. CONCLUSIONS This review could not provide evidence of improved neurological recovery after surgical treatment compared with nonoperative treatment. When surgical treatment was considered, there was a low level of evidence that fixation of the fracture results in better neurological improvement compared with isolated decompression. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Posterior tension band plate osteosynthesis for unstable sacral fractures: A preliminary study. J Clin Orthop Trauma 2019; 10:S106-S111. [PMID: 31695268 PMCID: PMC6823733 DOI: 10.1016/j.jcot.2019.05.017] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 02/14/2019] [Accepted: 05/21/2019] [Indexed: 11/26/2022] Open
Abstract
INTRODUCTION Stable reduction and rigid fixation of the sacrum and posterior ring structures are of paramount importance in the management of complex pelvic ring disruptions, Tile B and C. The major concern with the use of conventional methods, like iliosacral screws and iliolumbar fixations is the increased risk for surgical and implant-related morbidity, especially in difficult situations, such as comminuted, bilateral sacral fractures, and fractures in the dysmorphic sacrum. Although various biomechanical studies have reported the posterior trans-iliac plates to provide maximum resistance to distracting forces by the principle of tension band, the literature pertaining to this implication in clinical studies has been limited. The purpose of our study was to assess the efficacy of the trans-iliac plate in the management of unstable sacral fractures and its utility in pelvic disruptions associated with surgical site morbidity. METHODOLOGY The patients with unstable pelvic fractures (Tile B and C) between 2013 and 2017 were retrospectively analyzed at a trauma center. First, the anterior ring disruptions were stabilized, and then, the sacral fractures (Denis Zone 1-3) treated by posterior tension band plate osteosynthesis (3.5 mm reconstruction plate) were included. Demographic and perioperative data were assessed. The outcome variables studied were surgical morbidity, pain, loss of reduction, and union and implant-related complications. The outcomes were graded using Lindhal's (radiological) and Majeed (functional assessment) scores. RESULTS Thirteen patients (nine male/four female) with a median age of 42 years, had sacral fractures in Denis zones 1/2/3 (four/ten/one, respectively), resulting from Tile pelvic injury B and C were included. The pelvis in five patients was stabilized only with the posterior plate due to the anteriorly-associated surgical site morbidity (Morel-Lavallee lesions and urinary tract injuries). The mean follow-up was 21.5 ± 2.8 months. All fractures had a radiological union by 22 weeks; Lindhal's grade A in ten patients and grade B in three patients. Two out of three patients recovered from preoperative neurological involvement. Two had complained of implant prominence (BMI<19 kg/m2) and there were no implant failures. Four had excellent, six had good, and three had fair or poor functional outcomes. CONCLUSION The posterior trans-iliac plate is a minimally invasive and safe procedure that can be used in a wide range of unstable sacral fractures with notably less implant failure rate. The rigid posterior construct restores the principle tension between the iliac blades and minimizes the secondary displacement of the anterior disrupted structures, thereby useful in managing ring disruptions with surgical site morbidity.

Abstract
Patients suffer bilateral sacral plexus injuries experience severe problems with incontinence. We performed a cadaveric study to explore the anatomical feasibility of transferring ipsilateral S2 nerve root combined with a sural nerve graft to pudendal nerve for restoration of external anal and urethral sphincter function. The sacral nerve roots and pudendal nerve roots on the right side were exposed in 10 cadavers. The length from S2 nerve root origin to pudendal nerve at inferior border of piriformis was measured. The sural nerve was used as nerve graft. The diameters and nerve cross-sectional areas of S2 nerve root, pudendal nerve and sural nerve were measured and calculated, so as the number of myelinated axons of three nerves on each cadaver specimen. The length from S2 nerve root to pudendal nerve was 10.69 ± 1.67 cm. The cross-sectional areas of the three nerves were 8.57 ± 3.03 mm2 for S2, 7.02 ± 2.04 mm2 for pudendal nerve and 6.33 ± 1.61 mm2 for sural nerve. The pudendal nerve contained approximately the same number of axons (5708 ± 1143) as the sural nerve (5607 ± 1305), which was a bit less than that of the S2 nerve root (6005 ± 1479). The S2 nerve root in combination with a sural nerve graft is surgically feasible to transfer to the pudendal nerve for return of external urethral and anal sphincter function, and may be suitable for clinical application in patients suffering from incontinence following sacral plexus injuries.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinical outcomes of isolated decompression for patients with transverse sacral fractures and cauda equina syndrome, which have been rarely reported before. MATERIAL AND METHODS Twelve neurological impaired patients with transverse sacral fracture from January 2010 to March 2017 treated in our institution were evaluated. All patients went through isolated decompression and were followed for a minimum of 12 months. Fracture causes, classifications, associated injury, radiologic results, clinical outcomes using the Majeed index, and neurological outcomes using the Gibbons criteria were evaluated. RESULTS Motor vehicle accidents and falling injuries were the major causes of trauma. The average time from trauma to surgery was 89.8 days. Eleven patients underwent laminectomy with no more than 3 segments resected and 1 patient had S1-S4 excised. Three patients with fracture involving the lumbopelvic joint had L5 laminectomy. All patients achieved bony union, with 7 patients (63.6%) showing satisfactory pelvic outcome. Average Gibbons scores improved from 2.8 to 1.9 at 18-month average follow-up, but most patients were left with residual pain. No surgical-related complications were seen in any patients. CONCLUSIONS Isolated decompression can be considered for patients who present a stable sacrum with non-displaced fracture or an old fracture that shows fracture healing. Favorable pelvic outcomes and neurological recovery, along with acceptable stability, can be acquired.

Spinopelvic dissociation in patients suffering injuries from airborne sports. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2019; 29:2513-2520. [PMID: 31037422 DOI: 10.1007/s00586-019-05983-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 04/19/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Spinopelvic dissociation which is also called U-type or referred to H-type sacral fractures with a transverse fracture line is an infrequent injury that results mainly from high-energy accidents. This results in an osseous dissociation of the upper central segment of the sacrum and the entire spine from the lower sacral segments. The purpose was to investigate the incidence of spinopelvic fracture in general among airborne injuries. PATIENTS AND METHODS Using our electronic patient records, we retrospectively investigated all sacral fractures related to airborne sports between 2010 and 2017. All injuries were classified according to the Roy-Camille, Denis, AOSpine and the Tile classification system. RESULTS During the period of interest, 44 patients (18.7%) were admitted with sacral fractures after accidents obtained from airborne sports, including 16 spinopelvic dissociations (36.4%). The majority of these injuries were obtained from paragliding (75.0%), followed by BASE jumping (21.4%) and parachuting (4%). The mean injury severity score (ISS) in the spinopelvic dissociation group was significantly higher compared with other sacral fracture group (38.1 vs. 20.0; p < 0.001). Six lambda-type, four T-type, four H-type and two U-type injuries were identified. In total, four patients (25%) were found to have neurological impairment. For treatment, 87.5% of patients underwent subsequent surgical stabilization. CONCLUSION Airborne sports have high potential for serious, life-threatening injuries with a high incidence of spinopelvic dissociation. In the literature, the prevalence of spinopelvic dissociation in sacral fractures is described to be between 3 and 5%. In our series, the prevalence is 36.4%. It is important to identify the potential injuries promptly for the further treatment. These slides can be retrieved under Electronic Supplementary Material.

Abstract
INTRODUCTION Spinopelvic dissociation is a rare injury resulting in discontinuity between the spine and pelvis. We review the English- language literature and discuss critical treatment controversies. We present a series of spinopelvic dissociation cases from a level I trauma center. METHODS In this retrospective review of 18 consecutive cases treated surgically over a period of 4 years, we collected patient, injury, and surgical demographics and clinical and radiographic outcome measures. RESULTS Twelve patients had associated injuries, five were intubated on arrival, and six had neurologic deficits at presentation. No patient had spinal decompression, and all patients underwent closed reduction and percutaneous fixation. There were no cases of iatrogenic nerve injury, despite the use of partially threaded sacroiliac screws and closed reduction techniques. Five patients showed progressive neurologic improvement postoperatively. After reduction, eight patients (44%) had radiographic loss of the sacrococcygeal angle at the latest follow-up, but correction of fracture translation was preserved in all. DISCUSSION Spinopelvic dissociation represents a heterogeneous group of injuries often in the context of polytraumatized patients with other injuries. Our closed reduction and fixation technique resulted in satisfactory outcomes. We present a treatment algorithm for these rare injuries.

Abstract
OBJECTIVES To identify whether formal sacral decompression provides improvement in outcome for patients with neurologic deficit after sacral fracture compared with patients treated with indirect decompression and whether the timing of surgical decompression influences neurologic outcome? DATA SOURCES MEDLINE was searched via PubMed using combinations of the following search terms: "Sacral fracture," "Traumatic Sacral fracture," "Sacral fracture decompression," "Sacral fracture time to decompression," "Sacral Decompression." Only clinical studies on human subjects and in the English language were included. STUDY SELECTION Studies that did not provide sufficient detail to confirm the nature of the sacral injury, treatment rendered, and neurologic outcome were excluded. Studies using subjects less than 18 years of age, cadavers, nonhuman subjects, or laboratory simulations were excluded. All other relevant studies were reviewed in detail. DATA EXTRACTION All studies were assigned a level of evidence using the grading tool described by the Centre for Evidence-Based Medicine and all studies were analyzed for bias. Both cohorts in articles comparing 2 groups of patients treated differently were included in the appropriate group. Early decompression was defined as before 72 hours. DATA SYNTHESIS The effect of decompression technique and timing of decompression surgery on partial and complete neurologic recovery was estimated using a generalized linear mixed model to implement a logistic regression with a study-level random effect. CONCLUSIONS There was no benefit to early decompression within 72 hours and no difference between formal laminectomy and indirect decompression with respect to neurologic recovery.

Abstract
Fractures involving the central canal of the sacrum are rare injuries and can be transverse or longitudinal. Transverse fractures are by far common and associated with high incidence of neurological injuries. On the contrary, longitudinal midline split fracture is an extremely rare injury with minimal or no neurological injury. They are always associated with anterior pelvic ring fracture and are vertically stable needing only fixation of the anterior pelvic injury. Plating of the anterior pelvic ring in two planes would be beneficial than single plate to prevent gradual loss of reduction.

Abstract
Sacral fractures are uncommon lesions and most often the result of high-energy trauma. Depending on the fracture location, neurological injury may be present in over 50% of cases. In this article, the authors conducted a comprehensive literature review on the epidemiology of sacral fractures, relevant anatomy of the sacral and pelvic region, common sacral injuries and fractures, classification systems of sacral fractures, and current management strategies. Due to the complex nature of these injuries, surgical management remains a challenge for the attending surgeon. Few large-scale studies have addressed postoperative complications or long-term results, but current evidence suggests that although fusion rates are high, long-term morbidity, such as residual pain and neurological deficits, persists for many patients.

The effect of early operative stabilization on late displacement of zone I and II sacral fractures. Injury 2013; 44:199-202. [PMID: 23218677 DOI: 10.1016/j.injury.2012.11.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2012] [Revised: 09/18/2012] [Accepted: 11/04/2012] [Indexed: 02/02/2023]
Abstract
INTRODUCTION This study was designed to evaluate the effect on displacement of early operative stabilization on unstable fractures when compared to stable fractures of the sacrum. METHODS Patient consisted of those sustaining traumatic pelvic fractures that also included sacral fractures of Denis type I and type II classification, who were over 18 at the time of the study. Patients were managed emergently, as judged appropriate at the time and then subsequently divided into two cohorts, comprising those who were either treated operatively or non-operatively. The operative group comprised those treated with either internal fixation or external fixation. RESULTS Twenty-eight patients had zone II fractures, and 20 had zone I fractures. Zone II fractures showed average displacements of 6.5mm and 6.9mm in the rostral-caudal and anteroposterior directions, respectively, at final follow up. Zone I fractures had average displacements of 6.6mm and 6.1mm in both directions. There were no significant differences between zone I and II sacral fractures (rostral-caudal P=0.74, anteroposterior P=0.24). Average changes in fracture displacement in patients with zone I fractures were 0.6-1.0mm in both directions. Average changes in zone II fractures were 1.8-1.5mm in both directions. There were no significant differences between the average changes in zone I and II fractures in any direction (rostral-caudal P=0.64, anteroposterior P=0.68) or in average displacements at final follow up in any of zone or the entire cohort. Statistically significant differences were noted in average changes in displacement in zone II fractures in the anteroposterior plane (P=0.03) and the overall cohort in the anteroposterior plane (P=0.02). CONCLUSION Operative fixation for unstable sacral fractures ensures displacement at follow up is comparable with stable fractures treated non operatively.

Application triangular osteosynthesis for vertical unstable sacral fractures. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2012; 22:503-9. [PMID: 23132281 DOI: 10.1007/s00586-012-2561-z] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/01/2012] [Revised: 07/10/2012] [Accepted: 10/28/2012] [Indexed: 02/05/2023]
Abstract
PURPOSE The aim of this study was to explore the operative technique and effectiveness of triangular osteosynthesis for vertically unstable sacral fractures. METHODS From January 2009 to December 2010, 25 vertical unstable sacral fractures in 22 patients were treated with triangular osteosynthesis using the combination of universal spine system and iliosacral screw in our institution. Patients were followed up prospectively with routine post-operation visits for clinical and radiographic examination. The reduction quality was evaluated according to Matta criterion. Clinical function outcome, and nerve function outcome was evaluated by Majeed and Gibbons criterion. RESULTS All patients were followed up for an average of 14 months (range 8-26 months). Local infection was seen in two patients, and both were healed with debridement and antibiotics. Patients experienced early weight-bearing ability, no fracture reduction loss, and hardware loosening, while all fractures appeared as bone union at the final follow-up. According to Matta criterion for fracture reduction, the results were excellent in 18 sides, good in 6 sides, and fair in 1 side. According to Majeed functional scoring at last follow-up, the results were excellent in 13 cases, good in 6 cases, fair in 2 cases, and poor in 1 case. Neurologic impairment was noted in 13 patients pre-operative, six patients achieved complete recovery, six patients achieved partial improvement, one patient did not have any improvement at the last follow-up. CONCLUSION Triangular osteosynthesis is a relatively new fixation for vertical unstable sacral fractures, the fixation is rigid, permits early full weight-bearing, and nerve decompression can be performed, which facilitates function recovery.

Lumbopelvic fixation for multiplanar sacral fractures with spinopelvic instability. Injury 2012; 43:1318-25. [PMID: 22632803 DOI: 10.1016/j.injury.2012.05.003] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2012] [Revised: 05/02/2012] [Accepted: 05/02/2012] [Indexed: 02/02/2023]
Abstract
Sacral fractures with both transverse and bilateral vertical fracture components are by definition multiplanar fractures, and often present with spinopelvic instability and cauda equina deficits. The treatment is challenging. Between 2006 and 2009, we treated nine such patients at our trauma centre. There were six men and three women, with a mean age of 32.2 years. Preoperative neurologic deficits were noted in seven patients; four patients had complete cauda equina paralysis, and three patients had incomplete cauda equina syndrome. All patients were treated using lumbopelvic instrumented fixation without other devices for their multiplanar sacral fractures. Six patients who had neurological deficits and sacral canal compression underwent decompression laminectomy. The mean postoperative follow-up time was 21.7 months (range, 14-32 months). All fractures went on to union without loss of reduction or hardware failure. The mean Gibbons score improved from 3.5 preoperatively to 2.3 postoperatively among the patients who underwent decompression laminectomy. Eight out of nine patients had fair or better results based on radiographic criteria and the Majeed pelvic fracture outcome score. Our experience suggests lumbopelvic fixation can be used for the treatment of multiplanar sacral fractures with spinopelvic instability with a low rate of complications. Neurologic improvement can be expected, but whether surgical decompression results in substantially better neurologic recovery than conservative treatment remains uncertain.

A new classification for complex lumbosacral injuries. Spine J 2012; 12:612-28. [PMID: 22964014 DOI: 10.1016/j.spinee.2012.01.009] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2011] [Revised: 12/24/2011] [Accepted: 01/22/2012] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The optimal classification and treatment algorithm for complex lumbosacral injuries, in particular high-energy sacral fractures and lumbosacral dissociation (LSD) injuries, remains controversial. Currently used classification systems are largely descriptive, lacking validity, reproducibility, treatment considerations, and prognostic information. PURPOSE We set out to develop a comprehensive, yet practical, classification system for complex lumbosacral injuries that assists in clinical decision making. STUDY DESIGN We developed a new classification system for complex lumbosacral injuries derived through literature review, expert opinion, and our clinical experience treating combat casualties over the past 10 years. We have seen an increased incidence of complex sacral fractures and LSD injuries after high-energy blast trauma, motor vehicle collisions, and aircraft crashes. METHODS We performed an extensive literature review and discussed the proposed classification with spinal trauma surgeons from a variety of institutions familiar with the treatment of complex high-energy sacral fractures and LSD injuries. We identified the significant clinical and radiographic variables encountered in the decision-making process for the treatment of complex lumbosacral injuries. Existing classification systems were reviewed in light of these essential characteristics, and their limitations were defined and addressed with the new system. RESULTS A new classification system called lumbosacral injury classification system (LSICS) was devised based on three injury characteristics: injury morphology, posterior ligamentous complex integrity, and neurologic status. A composite injury severity score was calculated by summing a weighted score from each category, allowing patients to be stratified into surgical and nonsurgical treatment groups based on threshold values. Modifiers to determining appropriate selection for operative treatment include systemic injury load and physiological status of the polytraumatized patient, soft-tissue status, and expected time to mobility. Finally, an algorithm was developed to determine the optimum operative technique based on the previously outlined injury characteristics. CONCLUSIONS The LSICS provides a comprehensive and practical approach for evaluating injury severity and guiding clinical decision making. This system provides common language for surgeons to communicate various injury patterns and formulate treatment modalities. Further studies are necessary to determine the reliability and validity of this new classification system.

Spinal and pelvic injuries in airborne sports: a retrospective analysis from a major Swiss trauma centre. Injury 2012; 43:440-5. [PMID: 21762910 DOI: 10.1016/j.injury.2011.06.193] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2011] [Revised: 06/11/2011] [Accepted: 06/21/2011] [Indexed: 02/02/2023]
Abstract
BACKGROUND Adrenalin-seeking airborne sports like BASE-jumping, paragliding, parachuting, delta-gliding, speedflying, and skysurfing are now firmly with us as outdoor lifestyle activities and are associated with a high frequency of severe injuries, especially to the spine. METHODS Retrospective analysis of all airborne sports-associated spinal and pelvic injuries admitted to a Level I trauma centre in the Swiss Alps between 1st March 2000 and 31st October 2009. Spinal injuries were classified by the Magerl system and pelvic injuries by the AO/OTA scheme modified by Isler and Ganz. Spino-pelvic dissociation fractures in airborne sports were compared to similar injuries in the general trauma population using multiple logistic regression analysis. RESULTS 181 patients (11 BASE-jumpers, 144 paragliders, 19 parachuters, 1 speedflyer, 4 deltagliders, 2 skysurfer) were included. 161 (89%) were male. Median age was 37.0 years (IQR=29.0-47.0) and ISS 8 (IQR=4-13). 89 (49.2%) patients sustained spinal fractures. Type A fractures were predominant (91.5%), followed by Type C (5.3%) and Type B (3.2%). The level L1 was most often affected (35.1%). 17 patients (9.4%) had pelvic ring fractures. Most frequent were Type C fractures (41.2%), followed by Types A and B (29.4% each). 8 paragliders (4.4%) suffered spino-pelvic dissociation injuries. The odds ratio for sustaining such fractures in paragliders was 21-fold higher (OR 21.04, 95% CI 7.83-56.57, p<0.001) than in the general trauma population. CONCLUSIONS Serious spinal and pelvic injuries account for most injuries sustained during airborne sporting activities. The thoracolumbar region was most often affected, but the lumbopelvic junction is also especially vulnerable as high impact forces from vertical and horizontal deceleration need to be absorbed. The frequency of spino-pelvic dissociation was very high in paragliding injuries, with a 21-fold higher odds ratio than in the general trauma population.

Management of lumbosacropelvic fracture-dislocation using lumbo-iliac internal fixation. Injury 2012; 43:452-7. [PMID: 21925658 DOI: 10.1016/j.injury.2011.08.036] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2011] [Revised: 08/25/2011] [Accepted: 08/25/2011] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Traumatic lumbosacropelvic fracture-dislocation is a rare but potentially serious injury. Conventional methods like lumbosacral fixation used to treat such injuries often result in suboptimal outcome secondary to complications like pseudoarthroses, sagittal imbalance and hardware failure. In this study, we retrospectively analysed the clinical features and management for this trauma using lumbo-iliac fixation. METHODS Eight patients (6 male, 2 female; 21-52 years old, mean: 38.4) with traumatic lumbosacropelvic fracture-dislocation were surgically managed by lumbo-iliac internal fixation after lumbosacral decompression. Patients were followed up for 24-40 months (mean: 31.6). American Spine Injury Association (ASIA) scores were measured before surgery and at the last follow-up, and statistically analysed. RESULTS After surgery, all patients experienced improved sensory and motor performance. Six patients showed recovery of bowel and bladder functions. Immediately after lumbo-iliac fixation, all patients could turn in bed without assistance. Lumbosacral alignment was restored immediately after surgery and no dislocation was observed during follow-up. Radiography indicated excellent integration between the autograft and the vertebrae. After surgery, no patient experienced neurological deterioration. CONCLUSION Our experience with these cases suggests that early surgical decompression and posterior lumbo-iliac internal fixation can effectively restore spinal alignment, stabilise the spine, and improve neurological symptoms for this complex trauma.

Abstract
A 76-year-old man presented with a Denis Zone III sacral fracture after a traffic accident. He also developed urinary retention and perineal numbness. The patient was diagnosed with neurogenic bladder dysfunction caused by the sacral fracture. A computed tomogram (CT) revealed that third sacral lamina was fractured and displaced into the spinal canal, but vertebral body did not displace. The fracture lines began at the center of lamina and extended bilateraly. The fracture pattern was unique. The sacrum was osteoporosis, and this fracture may be based on osteoporosis. We performed laminectomy to decompress sacral nerve roots. One month after surgery, the patient was able to urinate. Three months after surgery, his bladder function recovered normally. One year after surgery, he returned to a normal daily life and had no complaints regarding urination. One-year postoperative CT showed the decompressed third sacrum without displacement.

Abstract
A highly unstable and neurological injury, the isolated U-shaped sacral fracture without pre-pelvic ring fracture but combined with cauda equina injury is rare in clinics, and the treatment method remains unclear. It can occur when patients fall from a height, the lower extremities hit the ground in extreme flexion, and the sacrum is the direct touchdown point. The direct impact on the sacrum and the vertical extrusion energy through the spinal column may be the main mechanism of injury. The U-shaped sacral fracture is easily missed, and diagnosis is often delayed as it is difficult to detect on anteroposterior view pelvic radiograph due to angulation of the fracture and bowel shadow. When clinical signs suggested a possible U-shaped sacral fracture, a 2- to 3-mm cut computed tomography scan with coronal and sagittal reconstruction can provide optimal imaging to identify and evaluate the sacral fracture.This article describes 2 patients, a 16-year-old girl and a 40-year-old man, with U-shaped sacral fractures. The patients were treated with posterior sacral laminectomy within 1 week after injury and achieved satisfactory postoperative recovery. Follow-up showed bony union with no further displacement or internal fixation failure, wound infection, delayed healing, or compression of the skin by the plate and screws. The results show that posterior vertebral plate decompression and reconstructive plate internal fixation can obtain a satisfactory outcome with minor operation trauma and few complications.

Abstract
STUDY DESIGN Technical note and retrospective first cases study. OBJECTIVE To present a novel surgical procedure for treating rare and challenging U-shaped fractures of the sacrum. SUMMARY OF BACKGROUND DATA U-shaped fractures of the sacrum are not frequent and usually seen in the context of high energy trauma (high-fall injury). There is no consensus about the therapeutic strategy. When surgery is decided on selected patients, the technique raises several issues for the neural decompression, reduction, and fixation. The L5-S1 mobility has to be sacrificed for most authors. METHODS Based on anatomic considerations, the authors present here the original surgical technique they have been using at their institution and a consecutive series of patients. The procedure associates a shortening osteotomy of the sacrum at the site of the fracture and a sacro-sacral fixation. RESULTS The proposed procedure was simple, safe, and effective. CONCLUSIONS Performing the osteotomy helps in the reduction and allows a short fixation, which spares the mobility of the lumbo-sacral junction.

Management of traumatic sacral fractures: a retrospective case-series study and review of the literature. Injury 2010; 41:266-72.

Abstract
BACKGROUND Being the result of high-energy trauma in most cases, traumatic sacral fractures are rare, difficult to recognise and frequently misdiagnosed. Furthermore they may lead to vascular injuries, mechanical instability, neurological impairment and increased morbidity. As a result, patients with traumatic sacral fractures may suffer major socio-economic consequences. OBJECTIVE This retrospective case-series study evaluated the functional, neurological, mental and emotional status of patients who had suffered traumatic sacral fractures and either followed conservative or underwent operative treatment at our department. PATIENTS AND METHODS We evaluated the clinical and radiographic results of all patients who had suffered traumatic sacral fractures between December 2003 and June 2007. The case-notes of all patients were reviewed, all co-existing injuries were registered and an ISS was calculated for each patient. At the latest follow-up visit, all patients completed the Short Form-36 questionnaire as well. RESULTS Sixteen patients (eleven male, five female) were included in this study. At the time of initial admission, the mean age of the patients was 30 years (range: 14-53) and the mean ISS was 33.2 points (range: 21-59). The mean follow-up period was 24.1 months (range: 13-40). Six patients were treated operatively (four patients diagnosed with some type of neurological impairment at their initial physical examination and two patients due to pelvic instability). The mean ISS of the patients who were treated operatively was 41.1 points (range: 21-59), whereas of those who were treated conservatively was 28.5 points (range: 21-45). No patient had any neurological deficit at his/her latest re-evaluation. Patients who were treated conservatively achieved the best scores in every domain of the SF-36 questionnaire, when compared with those who were treated operatively. CONCLUSION The diagnosis and management of sacral fractures may pose several dilemmas in everyday's clinical praxis. Patients suffering from traumatic sacral fractures who were treated conservatively seem to have better functional and mental/emotional outcomes, probably because their injuries were less severe than those of the patients who were treated conservatively.

U-shaped sacral fractures: surgical treatment and quality of life. Injury 2009; 40:1040-8. [PMID: 19442971 DOI: 10.1016/j.injury.2008.11.027] [Citation(s) in RCA: 61] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2008] [Revised: 11/25/2008] [Accepted: 11/27/2008] [Indexed: 02/02/2023]
Abstract
BACKGROUND U-shaped sacral fractures are rare and highly unstable pelvic ring fractures. They are not recognised in the standard classification systems of these fractures. The fracture pattern is associated with significant neurological injury and can lead to progressive deformity and chronic pain if not diagnosed and treated properly. In recent years a variety of surgical strategies have been shown to facilitate early mobilisation and reduce early mortality as compared to non-operative strategies. Poor evidence, however, has hampered the development of a standard treatment algorithm. As for the long-term morbidity, the influence of operative treatment may be difficult to assess due to associated injury. However, evidence exists that there is a significant effect on the long-term morbidity. OBJECTIVE To assess the injury characteristics, choice of treatment and quality of life of U-shaped sacral fractures. METHODS Eight polytraumatised patients with U-shaped sacral fractures were identified over a 7-year period and evaluated retrospectively. They were analysed for fracture classification, associated injury, and injury severity. Clinical and Radiological results were evaluated. Neurological outcome was retrospectively classified by Gibbons' criteria. Long-term quality of life outcome was evaluated using the EuroQoL-6D questionnaire. RESULTS The study population consists of five women and three men; with a median age of 29 years. All patients sustained severe associated injury. The Injury Severity Score ranged from 17 to 45 (median 23). The median time between trauma and definitive internal fixation was 4 days (range, 2-22 days). Definitive fixation included either percutaneous iliosacral screws (n=2), transsacral plate osteosynthesis (n=1) or triangular osteosynthesis with (n=4) or without transsacral plating (n=1). Early postoperative mobilisation and early partial weight-bearing were encouraged when possible. Follow-up ranged from 5 to 65 months (median, 36 months). Pain, mood disorders and mobility problems mainly influenced patients' present general health status. CONCLUSION U-shaped sacral fractures present a rare and heterogeneous injury. Operative treatment depended mainly on fracture type, associated spinal fractures, and the surgeon's preference. Long-term quality of life is dominated by pain, mood disorders and moderate mobility problems.

Abstract
From January 2004 to July 2007, 21 patients with injuries at the posterior pelvic ring were treated with locking compression plate osteosynthesis through a minimally invasive approach and followed up for a mean of 12.2 months. Preoperative and postoperative radiography was conducted to assess the reduction and union. The mean operation time was 60 minutes (range: 40-80). Intraoperative blood loss was 50-150 ml. All patients achieved union at the final follow-up. The overall radiological results were excellent or good in 17 patients (85%). The functional outcome was excellent or good in 18 patients (90%). There was no iatrogenic nerve injury, deep infection or failure of fixation. We believe that fixation with a locking compression plate is an effective method for the treatment of injuries of the posterior pelvic ring in view of its convenience, minimal traumatic invasion and lower morbidity.

Abstract
Vertically unstable sacral fractures often make it difficult to achieve rigid fixation and there is no consensus on the optimal fixation technique for these injuries. The purpose of this study was to evaluate complication rate and short-term outcome of vertically unstable sacral fractures treated by posterior transiliac plate fixation. We performed a retrospective review of prospectively collected data of patients who underwent posterior transiliac plating for sacral fractures at two institutions. All patients were treated with the standard posterior approach using a 4.5-mm reconstruction plate and followed for at least 12 months. Patients' demographics, Majeed functional questionnaire surveys, and radiographic outcomes were collected. There were 19 patients with a mean age of 37.5-years. The mean follow-up was 26.3 months. The most frequent mechanism of injury was a fall from a height. According to the AO/OTA classification, there were 10 C1, 6 C2, and 3 C3, which were classified as 2 Denis I, 20 Denis II, and 2 Denis III, including 5 bilateral sacral fractures. Neurological deficit at the initial examination was recorded in 10 patients. The mean ISS was 20.7 and the mean timing of the internal fixation was 6.4 days. Anterior internal fixation of pelvic ring was added in eight patients. A Morel-Lavallee lesion was identified in 5 patients during the operation. Reductions were graded as nine excellent, seven good, and three fair according to the method of Tornetta. There were two postoperative surgical wound infections, both occurring in patients with a Morel-Lavallee lesion. All the sacral fractures united eventually and no implant failure occurred, though there were two patients with a small loss of reduction (<5mm) over the follow-up period. A total of 18 patients completed the functional assessment with a mean score of 78.5 points. Posterior plate fixation of vertically unstable sacral fractures is effective in maintaining fracture reduction even in the presence of significant posterior comminution. We caution its use in the presence of a known Morel-Lavallee lesion, as this may increase the wound complication and infection risk.

Abstract
During a 4-year period, 32 patients with type C unstable sacral fractures were treated in our university hospital. All patients had neurological deficits as a result of their sacral fracture. The average age was 31.2 (range 22-54) years and the average Hannover Polytrauma Score (PTS) was 24 (range 19-40) points. Twelve patients had zone I fracture, ten had zone II fracture and ten patients had comminuted fractures involving both zones. All patients underwent surgical decompression and reconstruction plate internal fixation. The average follow up period was 24.4 (range 19-47) months. Twenty-one patients (65.6%) had complete neurological recovery, eight patients (25%) had partial recovery and three patients (9.4%) had no recovery. The relationship between radiological and functional scores was evident but insignificant (P = 0.434). Significantly, the neurological recovery was less favourable in older age groups, pedestrian trauma, vertical shear injuries, comminuted fractures, fifth lumbar root involvement, very low motor power grades and in patients presenting late. Concerning complications, four patients (12.5%) had early infection and five patients (15.6%) had late urological problems and heterotopic ossification. Consequently, we conclude that patients undergoing very early surgical decompression and only reconstruction plate internal fixation can achieve safe early ambulation and better neurological, functional and radiological results.

Abstract
Sacral fractures most commonly occur after pelvic ring injuries but occasionally in isolation. Although the true incidence of sacral fractures is unknown, an estimated 30% are identified late. Sequelae of inappropriately treated or untreated sacral fractures include persistent pain, decreased mobility, and neurologic compromise. Because these fractures often result from high-energy trauma, concomitant injuries should be suspected. A thorough physical examination, including a detailed neurologic assessment and radiographic evaluation, is necessary to determine treatment. Computed tomography of the pelvis/sacrum can provide significant information about fracture pattern. Surgical intervention, often as a combination of neural decompression and stabilization, is indicated in patients with neurologic deficits, significant soft-tissue compromise, and lumbosacral instability. Patient satisfaction with surgical intervention has not been definitively documented, although neurologic improvement with timely intervention has been noted.

Abstract
We report the third documented case of small bowel entrapment within a sacral fracture leading to small bowel obstruction. This important diagnosis is rare and difficult to make, even with current imaging methods. We report a case in which a segment of small bowel trapped in a Denis II fracture of the sacrum required laparotomy, small bowel resection, and an omental patch over the fracture site. In this case the outcome was favorable with no residual sequelae.

STUDY DESIGN A prospective, longitudinal single-cohort study of 32 patients treated with internal fixation for unstable sacral fractures. OBJECTIVES To describe the prevalence of associated injuries in blunt pelvic trauma with unstable sacral fractures, and to characterize late impairments. SUMMARY OF BACKGROUND DATA In high-energy pelvic ring injury, the close association of the spine, the intrapelvic organs and the bony pelvic ring result in high risk for additional injuries. These injuries may result in long-term sequels pertaining to mobility, voiding, bowel function, and sexual function. However, little is known about the components of long-term morbidity after unstable sacral fractures. METHODS The minimum 1-year follow-up included 32 patients surgically treated for unstable sacral fractures. Patients were analyzed for associated injuries, fracture classification, severity of trauma, and long-term measures of neurologic recovery, mobility, and functions pertaining to voiding, defecation, and sexual function. RESULTS Additional injuries occurred in 84%. Injury Severity Score was 27 (range, 9-57). At follow-up, sensory impairments were observed in 91%; impaired gait in 63%, and bladder, bowel, or sexual impairments in 59%. Sacral radiculopathies explained only 60% to 69% of these impairments. The presence of late impairments correlated to the severity of injury and to the presence of associated injuries, but not to fracture characteristics. CONCLUSIONS Unstable fractures of the sacrum are frequently associated with additional injuries. These injuries have a significant effect on morbidity still 1 year after injury. The multifactor etiology of impairments after sacral fractures should be acknowledged in the assessment of these patients.

Abstract
PURPOSE To report results of sacral decompression and lumbopelvic fixation in neurologically impaired patients with highly displaced, comminuted sacral fracture-dislocations resulting in spino-pelvic dissociation. DESIGN Retrospective clinical study. SETTING Regional level one trauma center. PATIENTS Nineteen patients with highly displaced, comminuted, irreducible Roy-Camille type 2-4 sacral fractures with spino-pelvic instability patterns and cauda equina deficits were identified over a 6-year period, 18 of which met the 12-month minimum follow-up criterion. INTERVENTION All were treated with open reduction, sacral decompression, and lumbopelvic fixation. Radiographic and clinical results were evaluated. Neurological outcome was measured by Gibbons' criteria. MAIN OUTCOME MEASUREMENTS Radiographic evaluation with computed tomography scan and antero-posterior, lateral, and oblique views of the pelvis to assess alignment, hardware position and decompression. Clinical evaluation emphasizing neurological outcome as described by Gibbons' criteria. RESULTS Sacral fractures healed in all 18 patients without loss of reduction. Average sacral kyphosis improved from 43 to 21 degrees. Fifteen patients (83%) had full or partial recovery of bowel and bladder deficits, although only 10 patients (56%) had improved Gibbons scores. Average Gibbons score improved from 4 to 2.8 at 31-month average follow-up (range: 12 to 57 mo). Wound infection (16%) was the most common complication. Complete recovery of cauda equina function was more likely in patients with continuity of all sacral roots (86% vs. 0%, P = 0.00037) and incomplete deficits (100% vs. 20%, P = 0.024). Although not statistically significant, recovery of bowel and bladder function specifically was more closely associated with absence of any sacral root discontinuity (86% vs. 36%, P = 0.066) than on completeness of the injury (100% vs. 47%, P = 0.21). CONCLUSIONS Lumbopelvic fixation provided reliable fracture stability and allowed consistent fracture union without loss of alignment. Neurological outcome was, in part, influenced by completeness of injury and presence of sacral root disruption.

Surgical management of transforaminal sacral fractures. INTERNATIONAL ORTHOPAEDICS 2005; 29:333-7.

Abstract
Fourteen patients with transforaminal sacral fractures were treated with posterior iliosacral instrumentation. Patients were assessed in terms of surgical technique and functional results. A subjective functional scoring with a five-point scale was performed at the last follow-up. Activity pain, pain at rest, limping and patient satisfaction were evaluated. By considering symptom and satisfaction scores, subjective functional assessment revealed that ten patients had excellent results, two good and two moderate. There were no patients with poor functional outcome. The surgical technique is not a new concept. Combining sacral bar and pediculo-iliac fixation methods, provides vertical as well as horizontal stability and allows early weight bearing, the methods has many advantages. However, vertical and horizontal stabilities achieved by this technique may require further assessment with comparative biomechanical studies.
