Percutaneous Vertebroplasty with Side-Opening Cannula or Front-Opening Cannula in the Treatment of Kummell Disease?

Percutaneous short segmental fixation combined with bone cement augmentation for stage III Kümmell's disease without nerve deformity

The objective of this study was to evaluate the safety and efficacy of percutaneous pedicle screw fixation combined with bone cement augmentation in the management of stage III Kümmell disease without nerve deformity. A retrospective analysis was conducted on 17 patients diagnosed with stage III Kümmell disease without nerve deformity, who underwent treatment with percutaneous pedicle screw fixation combined with bone cement augmentation between April 2019 and 2022. Preoperative, postoperative, and final follow-up clinical outcome measures were collected, including Visual Analog Scale scores and Oswestry Disability Index scores. Additionally, lateral radiography was used to measure the Cobb angle and height of the anterior border of the affected vertebral body. Operative time, volume of injected bone cement, intraoperative cement leakage, and other complications were recorded. All patients underwent successful surgery, resulting in significant reductions in Visual Analog Scale scores, Oswestry Disability Index scores, and Cobb angle postoperatively; meanwhile there was a significant increase in height of the anterior border of the affected vertebral body. No major complications occurred during the follow-up period. In conclusion, percutaneous pedicle screw short-segment fixation combined with bone cement augmentation appears to be an effective surgical option for treating stage III Kümmell disease without nerve deformities.

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.

The Use of Three-Column Enhanced Percutaneous Vertebroplasty to Treat Kummell's Disease

Purpose

To describe the operative technique and clinical effects of three-column enhanced percutaneous vertebroplasty used to treat Kummell’s disease.

Methods

From April 2017 to April 2020, 39 patients with Kummell’s disease were treated via three-column enhanced percutaneous vertebroplasty. There were 12 males and 27 females of average age 70.23 ± 7.41 years. The operative time, volume of bone cement injected, and intraoperative cement leakage were recorded. The patients were re-examined postoperatively. The VAS was used to evaluate low back pain and the ODI score to evaluate improvement in the quality-of-life.

Results

All patients were successfully operated upon; the average operation time was 35.1±4.7 min and average volume of bone cement injected 4.5±0.92 mL. Five cases exhibited bone cement leakage during operation, two into the intervertebral disc and three into the anterior upper margin of the vertebral body. No leakage into the vertebral canal occurred. The average hospital stay was 2.50±0.86 days. The VAS score before operation was 7.47±0.24, but low back pain symptoms were significantly relieved after operation (P < 0.05). The VAS scores at 1 day and 1, 3, 6, and 12 months after operation were 2.91±0.09, 2.04±0.07, 1.59±0.05, 1.28±0.15, and 0.8±0.18, respectively. The preoperative ODI score was 72.97±1.45 and significantly decreased postoperatively (P < 0.05), being 30.08±1.79 at 1 day, and 25.35±0.94, 23.19±1.76, 20.49±0.65, and 20.05±0.58 at 1, 3, 6, and 12 months after operation respectively.

Conclusion

Three-column enhanced percutaneous vertebroplasty effectively treats Kummell’s disease. The surgical trauma is low, recovery rapid, and bone cement fixation firm, especially in patients with stage I and II disease.

Percutaneous Kyphoplasty Versus Percutaneous Vertebroplasty for Neurologically Intact Osteoporotic Kümmell's Disease: A Systematic Review and Meta-Analysis

STUDY DESIGN

Systematic review and meta-analysis.

OBJECTIVE

Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are minimally invasive techniques widely used for the treatment of neurologically intact osteoporotic Kümmell's disease (KD), but which treatment is preferable remains controversial. Therefore, this study aimed to shed light on this issue.

METHODS

Six databases were searched for all relevant studies based on the PRISMA guidelines. Two investigators independently conducted a quality assessment, extracted the data and performed all statistical analyses.

RESULTS

Eight studies encompassing 438 neurologically intact osteoporotic KD patients met the inclusion criteria. Compared to PVP, PKP was associated with greater improvement in the short- and long-term Cobb angle [SMD = -0.37, P = 0.007; SMD = -0.34, P = 0.012], short-term anterior vertebral height [SMD = 0.43, P = 0.003] and long-term middle vertebral height [SMD = 0.57, P = 0.012] and a lower cement leakage rate [SMD = 0.50, P = 0.003] but produced more consumption (cement injection volume, operative time, fluoroscopy times, intraoperative blood loss and operation cost). However, there were no differences between the 2 procedures in the short- and long-term VAS and ODI scores, long-term anterior vertebral height, overall complications or new vertebral fractures.

CONCLUSIONS

Both procedures are equally effective for neurologically intact KD in terms of the clinical outcomes, with the exception of a lower cement leakage risk and better radiographic improvement for PKP but greater resource consumption. Based on the evidence available, good clinical judgment should be exercised in the selection of patients for these procedures.

Impending cauda equina syndrome due to Kummell disease; A case report and literature review

Introduction

Kummell disease (KD) is a rare cause of vertebral fracture due to osteonecrosis. The natural history of the disease is characterized by a previous minor trauma, a subclinical window period, and then a symptomatic period presenting with disabling pain, kyphosis, or neurologic deficit.

Importance

As an important but rare cause of non-discogenic cauda equina syndrome.

Case presentation

Here, we report on a wheelchair-bound 28-years-old bodybuilder man with KD who presented with progressive paresthesia and weakness of both legs (impending cauda equina syndrome) due to L5 involvement. He had a past medical history of arbitrary use of licensed and unlicensed drugs in the fitness field. The patient underwent posterior decompression, spinopelvic stabilization, and fusion. Postoperative rehabilitation was satisfactory and after six months, the leg muscle strength returned to normal and the patient's back pain disappeared.

Conclusion

KD should be considered as a rare differential diagnosis when dealing with any patient with a vertebral fracture associated with a history of minor trauma and an asymptomatic window period.

•

A case of Kummell disease in a rare location (L5 vertebra) was reported.

•

The usual consequence of this disease is a compression fracture in a neurologically intact patient.

•

In our case, the creation of a burst fracture induced cauda equina syndrome.

•

This case represents a rare cause of non-discogenic cauda equina syndrome.

•

Our patient unlike most individuals with Kummell disease, due to significant neurologic deficit needed open surgery.

Clinical Observations of Kümmell Disease Treatment Through Percutaneous Fixation Combined with Vertebroplasty

OBJECTIVE

To explore the safety and efficacy of percutaneous pedicle screw fixation combined with vertebroplasty for the treatment of stage III Kümmell disease.

METHODS

The clinical data and follow-up results of 22 patients with Kümmell disease who were admitted to our department from 2014 to 2018 were analyzed. There were 14 females and eight males, and the Age range was 58-81 years. All patients were followed up for 24 months. The treatment method was percutaneous pedicle screw fixation combined with vertebroplasty. The patient general information such as age, gender, bedrest time and location of fracture vertebrae were recorded. The clinical symptoms and imaging data of visual analogue scale (VAS), bone cement leakage, Oswestry Disability Index (ODI), Cobb angle, anterior, middle and posterior height of the diseased vertebral body, and complications were recorded before operation and during follow-up.

RESULTS

For patients enrolled, no bone cement leakage was observed during the operation; no patients developed infections after operation. The operation was safe and resulted in a short bedrest time. The VAS score and ODI index at 3 and 24 months postoperative (2.86 ± 0.83, 31.68% ± 6.21%; 3.0 ± 0.82, 32.78% ± 6.05%) were significantly lower than that recoded preoperatively (7.59 ± 0.59, 71.5% ± 8.84%) (P < 0.05). Additionally, there was no significant difference between the records at 3 and 24 months after operation (P > 0.05). Imaging data showed that the bone cement and screws were in good position and did not move during postoperative and follow-up. The anterior, middle and posterior height of the diseased vertebral body measured 2 days after surgery (23.46 ± 4.72, 23.12 ± 3.05, 25.81 ± 2.22) and at last follow-up (20.83 ± 4.48, 21.78 ± 2.74, 24.74 ± 1.93) were higher than that recorded preoperatively (13.08 ± 4.49, 12.93 ± 3.53, 19.32 ± 2.73) (P < 0.05), and the Cobb angle measured 2 days and 24 months after operation (9.57 ± 4.63, 10.68 ± 3.97) were lower than that recorded preoperatively (28.24 ± 8.95) (P < 0.05), and no significant difference was found between the values recorded at 2 days and 24 months after operation (P > 0.05). Follow-up for 24 months, there was no re-fracture of the diseased vertebrae and internal fixation loosening, but two cases of adjacent vertebral refracture complications occurred, and the effect was good after PVP treatment.

CONCLUSION

Short-segment percutaneous pedicle screw fixation combined with vertebroplasty in the treatment of stage III Kümmel disease can effectively restore the height of the diseased vertebrae, kyphosis correction, reduce trauma, prevent the diseased vertebral body from collapsing again, and effectively improves clinical symptoms.

Modified poly(methyl methacrylate) bone cement in the treatment of Kümmell disease

Kümmell disease (KD) causes serious vertebral body collapse in patients. However, only a few case reports have been conducted and the number of patients with KD investigated was limited. Additionally, the frequently used poly(methyl methacrylate) (PMMA) bone cement for KD is limited by excessive modulus and poor biocompatibility. Herein, we aimed to modify PMMA bone cement with mineralized collagen (MC), and compare the clinical effects, image performance and finite element analysis between the modified bone cement and PMMA bone cement for the treatment of phase I and II KD. Thirty-nine KD patients treated with PMMA bone cement and 40 KD patients treated with MC-modified PMMA bone cement from June 2015 to March 2017 were retrospectively analyzed. The surgical procedure, intraoperative blood loss, hospital stay and complications were compared between different groups. Visual analog scale, Oswestry disability index, anterior vertebral height, posterior vertebral height, computed tomography value, adjacent vertebral re-fracture, Cobb angle and wedge-shaped correction angle were evaluated. Additionally, the representative sample was selected for finite element analysis. We found that the MC-modified PMMA bone cement could achieve the same effect as that of PMMA bone cement and was associated with better vertebral height restoration in the long term.
