Short-segment decompression and fixation for thoracolumbar osteoporotic fractures with neurological deficits

Comparison between percutaneous short-segment fixation and percutaneous vertebroplasty in treating Kummell's disease: A minimum 2-year follow-up retrospective study

BACKGROUND

Percutaneous kyphoplasty (PKP) or percutaneous short-segment fixation (PSSF) is often used to treat Kummell's disease. However, it is not clear which treatment is better for patients.

OBJECTIVE

To retrospectively compare the clinical efficacy of PVP and PSSF for the treatment of Kummell's disease.

METHOD

60 patients were involved in this research and the period of follow-up was at least 2 years. 27 of them were treated with PVP (Group I) and the rest who received PSSF (Group II). The visual analog scale (VAS) and radiographic indexes of each participant had been measured preoperatively as well as 1 week, 3 months, and 2 years postoperatively. Additionally, the Oswestry Disability Index (ODI) scores were assessed at the last time point.

RESULTS

Comparing the two groups, no statistical significance was found among all parameters preoperatively. The time of operations and blood loss is less in Group I. At each time point after operation, the imaging indices in Group II are lower (P< 0.05). One week after treatments, the VAS scores are lower in Group I, and similarly, 3 months are the same (P< 0.05), while VAS are similar at the last time point. In the aspect of ODI scores, they are lower in Group II during long-term follow-up.

CONCLUSION

For the treatment of Kummell's disease, both PVP and PSSF have been found to be effective. PVP can provide rapid pain relief with a shorter operation time. However, in cases with severe kyphosis deformity, PSSF should be given priority.

Perioperative morbidity and mortality in octogenarians sustaining traumatic osteoporotic type 4 and 5 thoracolumbar and lumbar fractures: a retrospective study with 3 years follow-up

PURPOSE

This study aimed to guide the more efficient management of type 4 and 5 thoracolumbar or lumbar osteoporotic fractures (OF) in patients aged 80 years and older with an acute onset of neurological decline. This aim was achieved by assessing the clinical course and morbidity and mortality rates and identifying potential risk factors for patient mortality METHODS: Electronic medical records were retrieved from a single institution pertaining to the period between September 2005 and December 2020. Data on patient demographics, neurological conditions, surgical characteristics, complications, hospital course, and 90-day mortality were also collected.

RESULTS

Over a 16-year period, 35 patients aged ≥80 years diagnosed with thoracolumbar and lumbar OF were enrolled in the study. The mean Charlson comorbidity index (CCI) was >6, indicating a poor baseline reserve (9.4 ± 1.9), while cardiovascular diseases were the most prevalent among comorbidities. The mean surgical duration was 231.6 ± 89.3 min, with a mean blood loss of 694.4± 200.3 mL. The in-hospital was 8.6% and 90-day mortality rates at 11.4%. Two patients underwent revision surgery for deep wound infection. Intraoperative and postoperative radiography and computed tomography (CT) imaging revealed correct screw placement. Proper alignment of the thoracolumbar spine was achieved in all the patients. Unique risk factors for mortality included the presence of comorbidities and the occurrence of postoperative complications.

CONCLUSIONS

Emergent instrumentation in patients with acute onset of neurological decline and potentially unstable spines due to thoracolumbar and lumbar OF improved functional outcomes at discharge. Age should not be a determinant of whether to perform surgery.

Decompression and fusion surgery for osteoporotic vertebral fractures: WFNS Spine Committee Recommendations

INTODUCTION

Osteoporotic vertebral fractures (OVF) are common due to aging populations. Their clinical management remains controversial. Although conservative approaches are sufficient in most cases, there are certain conditions where decompression or fusion surgery are necessary. This manuscript aims to clarify the indications and types of surgeries for OVF.

EVIDENCE ACQUISITION

A Medline and Pubmed search spanning the period between 2010 and 2020 was performed using the keywords "osteoporotic vertebral fractures and decompression surgery" and "osteoporotic vertebral fractures and fusion surgery". In addition, we reviewed up-to-date information on decompression and fusion in osteoporotic vertebral fracture (OVF) to reach an agreement in two consensus meetings of the World Federation of Neurosurgical Societies (WFNS) Spine Committee that was held in January and February 2021. The Delphi method was utilized to improve the validity of the questionnaire.

EVIDENCE SYNTHESIS

A total of 19 studies examining decompression and fusion surgery in OVF were reviewed. Literature supports the statement that decompression and fusion surgery are necessary for progressive neurological deficits after OVF. The Spine Section of the German Society for Orthopedics and Trauma (DGOU) classification revealed that it might help make surgical decisions. We also noted that in patients planning to undergo surgery to correct significant kyphosis after OVF, several techniques, including multilevel fixation, cement augmentation, preservation of sagittal balance, and avoiding termination at the apex of kyphosis are necessary to prevent complications. Additionally, it became clear that there is no consensus to choose the type of open surgery (anterior, posterior, combined, using cement or bone or vertebral body cage, the levels, and kind of instrumentation). The current literature indicated that implant failure in the osteoporotic spine is a common complication, and many techniques have been described to prevent implant failure in the osteoporotic spine. However, the superiority of one method over another is unclear.

CONCLUSIONS

Open surgery for osteoporotic vertebral fractures should be considered if neurologic deficits and significant painful kyphosis. The apparent indications of surgery and most ideal surgical technique for OVF remain unclear in the literature; therefore, the decision must be individualized.

Dorsal instrumentation with and without vertebral body replacement in patients with thoracolumbar osteoporotic fractures shows comparable outcome measures

PURPOSE

In the surgical treatment of osteoporotic spine fractures, there is no clear recommendation, which treatment is best for the individual patient with vertebra plana and/or neurological deficit requiring instrumentation. The aim of this study was to evaluate clinical and radiological outcomes after dorsal or 360° instrumentation of osteoporotic fractures of the thoracolumbar spine in a cohort of patients representing clinical reality.

METHODS

A total of 116 consecutive patients were operated on between 2008 and 2020. Inclusion criteria were osteoporotic fracture, thoracolumbar location, and dorsal instrumentation. In 79 cases, vertebral body replacement (VBR) was performed additionally. Patient outcomes including complications, EQ-5D at follow-up, and sagittal correction were analyzed.

RESULTS

Medical and surgical complications occurred in 59.5% of patients with 360° instrumentation compared to 64.9% of patients with dorsal instrumentation only (p = 0.684). Dorsal instrumentation plus VBR resulted in a sagittal correction of 9.3 ± 7.4° (0.1-31.6°) compared to 6.0 ± 5.6° (0.2-22.8°) after dorsal instrumentation only, respectively (p = 0.0065). EQ-5D was completed by 79 patients after 4.00 ± 2.88 years (0.1-11.8 years) and was 0.56 ± 0.32 (- 0.21-1.00) for VBR compared to 0.56 ± 0.34 (- 0.08-1.00) without VBR after dorsal instrumentation (p = 0.994).

CONCLUSION

360° instrumentation represents a legitimate surgical technique with no additional morbidity even for the elderly and multimorbid osteoporotic population. Particularly, if sufficient long-term construct stability is in doubt or ventral stenosis is present, there is no need to abstain from additional ventral reinforcement and decompression.

Comparison of Perioperative Complications Between Anterior Fusion and Posterior Fusion for Osteoporotic Vertebral Fractures in Elderly Patients: Propensity Score-Matching Analysis Using Nationwide Inpatient Database

STUDY DESIGN

This was a retrospective cohort study using a nationwide inpatient database.

OBJECTIVE

The objective of this study was to evaluate the perioperative complications post-anterior fusion (AF) and posterior fusion (PF) for osteoporotic vertebral fractures (OVFs) with a large National Inpatient Database.

SUMMARY OF BACKGROUND DATA

OVF of the thoracolumbar spine often occur because of bone fragility and low-energy trauma in elderly patients. Though AF and PF are 2 representative surgical methods, there have been few studies focusing on perioperative complications of each method.

MATERIALS AND METHODS

The total 2446 (AF: 435 cases, PF: 2011 cases) patients who diagnosed thoracic or lumbar OVF and received either AF or PF were included from 2012 to 2016 with the Diagnosis Procedure Combination (DPC) database. After one-to-one propensity score-matching, total 866 cases were analyzed to evaluate systemic and local complication rates, reoperation rates, costs, and mortality.

RESULTS

A total of 433 pairs were made between the surgical procedures after matching. At least 1 systemic complication was seen in 26.6% of the AF group compared with 16.9% of the PF group (P=0.001). Specifically, the incidence of pulmonary embolism (P=0.045), urinary tract infection (P=0.012), and pleurisy (P=0.004) were significantly higher in the AF group. Blood transfusion (P=0.007) and the operation for systemic complications (P=0.020) were required more often in the AF group. The cost for hospitalization was also higher in the AF group (P<0.001). There were no differences in the mortality rates between the 2 groups.

CONCLUSIONS

More systemic complications were observed in the AF group. Surgeons need to take careful consideration of the merits and demerits described in this study when deciding the surgical method for OVF.

The influence of topical use of tranexamic acid in reducing blood loss on early operation for thoracolumbar burst fracture: a randomized double-blinded controlled study

Purpose

To investigate the safety and efficacy of topical use of tranexamic acid (TXA) on early operation for thoracolumbar burst fracture (TBF).

Methods

Patients with acute TBF requiring early decompression were prospectively collected. The enrolled patients were randomly assigned to TXA and control group, in which wound surface was soaked with TXA or the same volume of normal saline for 5 min after wound incision, respectively. The total blood loss (TBL), intraoperative blood loss (IBL), postoperative blood loss (PBL), hemoglobin (HGB) levels on preoperatively (pre-op) and postoperatively, and amount of allogenic blood transfusion were recorded. Furthermore, the general information was also compared between groups.

Results

There were 39 and 37 patients enrolled in TXA and control group for final analysis. The demographics data showed no significant difference between groups (P > 0.05), but operation time and IBL were significantly decreased in TXA group (P < 0.05). Further analysis showed that HGB level was significantly higher in the TXA group at POD1, while the TBL and PBL were significantly less than those in the control group (P < 0.05), but similar to HBL (P > 0.05). The postoperative ambulation time, removal time of drainage tube, length of hospital stay, and blood transfusion rate were also significantly less in TXA group (P < 0.05). At the final follow-up, no neurological deteriorations and no TXA-related complications were observed in both groups.

Conclusion

This RCT first demonstrated that topical TXA usage after wound incision could effectively reduce IBL without increasing risk of complications, beneficial to enhanced recovery after early operation for TBF.

Risk factors related to perioperative systemic complications and mortality in elderly patients with osteoporotic vertebral fractures-analysis of a large national inpatient database

BACKGROUND

The surgical treatment of osteoporotic vertebral fractures (OVF) is generally associated with a high risk of complications due to an aging population with osteoporosis; however, the detailed risk factors for systemic complications and mortality have not been clarified. We evaluated the risk factors for systemic complications and mortality in surgically treated OVF patients using a large national inpatient database.

METHODS

Patients over 65 years old who were diagnosed with OVF and received either anterior fusion (AF) or posterior fusion (PF), from 2012 to 2016, were extracted from the diagnosis procedure combination (DPC) database. In each of the perioperative systemic complications (+) or (-) group, and the in-hospital death (+) or (-) group, we surveyed the various risk factors related to perioperative systemic complications and in-hospital death.

RESULTS

The significant factors associated with systemic complications were older age (OR 1.38, 95% CI 1.09-1.74), a lower activity of daily living score upon admission (OR 1.52, 95%CI 1.19-1.94), atrial fibrillation (OR 2.14, 95%CI 1.25-3.65), renal failure (OR 2.29, 95%CI 1.25-4.20), and surgical procedure (AF, OR 1.73, 95%CI 1.35-2.22). The significant explanatory variables for in-hospital death were revealed to be male sex (OR 3.26, 95%CI 1.20-8.87), a lower body mass index (OR 3.97, 95%CI 1.23-12.86), unscheduled admission (OR 3.52, 95%CI 1.17-10.63), atrial fibrillation (OR 8.31, 95%CI 2.25-30.70), renal failure (OR 7.15, 95%CI 1.32-38.77), and schizophrenia (OR 8.23, 95%CI 1.66-42.02).

CONCLUSIONS

Atrial fibrillation and renal failure as preoperative comorbidities were common factors between perioperative systemic complications and mortality in elderly patients for OVF.

A New Technique That Percutaneous Endoscopic Decompression and Vertebroplasty in a Patient With Osteoporotic Vertebral Fracture: A Case Report

STUDY DESIGN

Technique note.

OBJECTIVE

To evaluate the feasibility of endoscopy in various spinal pathologies.

SUMMARY OF BACKGROUND DATA

Osteoporotic vertebral fractures are a common pathology in the elderly. These fractures are often accompanied by serious complications such as neurological deficits due to the compression of the spinal cord or nerve roots.

METHODS

A 78-year-old female patient presented to our hospital with a severe pain in her left leg and back. Lumbar magnetic resonance imaging and computed tomography scan revealed an osteoporotic L3 burst fracture compressing the left L3 nerve root. A minimally invasive translaminar endoscopic approach was used to remove the fractured fragment and cement was injected into the L3 vertebra. The patient was mobilized the same evening and was relieved of her pain.

CONCLUSION

Minimally invasive endoscopy is a safe and effective alternative to conventional major decompression with or without posterior stabilization, particularly in elderly patients with serious comorbidities.
