Disclosures
• I have nothing to disclose
What Is A Compression Fracture?
• Fracture of vertebral body
• Due to diminished bone strength• Osteoporosis• Tumor
• Infection• Long term steroid use
• Public health problem
• Frequently unnoticed• 1:3 come to clinical attention
• By 2040• World population > 65 y/o expected to double (1.3 billion)
• 14% of total population• More people/ society burden with osteoporosis and fractures
• If fracture rate remains same• 2040 increased total # fractures by 48%
• >3million annually
• $25.3 Billion annually
4
Risk Factors
• Most patients who fracture do not have osteoporosis by WHO criteria• Stone, et al. (2003)
• Only 39% with vertebral fracture had WHO DEXA dx of osteoporosis
• Prior compression fracture• Diagnostic of osteoporosis
• National Osteoporosis Foundation: “A vertebral fracture is consistent with a diagnosis of osteopororsis, even in the absence of bone density diagnosis, and is an indication for pharmacologic treatment with osteoporosis medication to reduce fracture risk”
• Highly predictive of future fracture• Presence of a fracture is better predictor then BMD for future fracture
• Fracture risk increases exponentially with increased # and severity of VCF• Called “fracture cascade”
• 9% reduction in FV with each compression Fx• 40% of “older” women will have kyphosis
• Only 1/3 will have fractures found on x‐ray• Kyphosis is exacerbated by degenerative disc disease• Increases “fracture cascade” and risk of future fracture
• Bone loss• Significant cortical and trabecular bone loss with prolonged bed rest
• Muscle strength loss• 10‐15% loss weekly with complete bed rest
• Fracture on x ray• Neurologic deficit• Unable to obtain good x rays
• Allows good visualization of the posterior elements
• Visualizes spinal canal and degree of neural compromise
• Evaluate posterior element involvement with a burst fracture
• Disadvantage• Inability to detect subtle horizontally fractures of vertebral bodies, pedicles, or lamina• Minimal vertebral body compression fractures may be missed• Might be overcome by frontal & sagittal reformation
• Indications• Majority of patients can be treated with observation and gradual return to activity • PLL intact (even if > 30 degrees kyphosis or > 50% loss of vertebral body height)
• Pain medication• Pain usually resolves in 6‐12 weeks• NSAIDS/ COX‐2 inhibitors with caution• Narcotics with caution• Muscle relaxers best in first 2 weeks
• If the fracture is less than five days old calcitonin can be used for four weeks to decrease pain• (AAOS) “Patients who present with an osteoporotic spinal compression fracture on imaging with correlating
clinical signs and symptoms suggesting an acute injury (0‐5 days after identifiable event or onset of symptoms) and who are neurologically intact be treated with calcitonin for 4 weeks.” Strength of Recommendation: Moderate
• Medical management can consist of bisphosphonates to prevent future risk of fragility fractures
• (AAOS) “Ibandronate and strontium ranelate are options to prevent additional symptomatic fractures in patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms.” Strength of Recommendation: Limited
• Reduce pain, stabilize spine, and limit progression of deformity
• Earlier mobilization/ reduced bed rest
• Some patients may benefit from an extension orthosis although compliance can be an issue
• (AAOS) “Unable to recommend for or against treatment with a brace for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Inconclusive
• Most pts can be treated symptomatically w/ short period of bed rest until pain is diminished; • (AAOS) “Unable to recommend for or against bed rest, complementary and alternative medicine, or opioids/analgesics for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Inconclusive
• Rarely an NG tube is required for severe ileus• If bowel sounds and flatus are not present then patient should be made NPO, should receive IV Fluid
• Early ambulation is encouraged in a hyperextention orthosis
13
Non‐Operative Treatment
• Avoid compression overload for 8‐12 weeks
• Depending on degree of compression• pt may be treated effectively by hyperextension exercises
• avoidance of compression overloads for period of approximately 12 weeks.
• Early ambulation is encouraged in a hyperextension orthosis.• No bending, stooping, twisting, or lifting more than 20 lbs
• Avoid bone and muscle loss• May need pain meds and muscle relaxers
• Can assist with pain management, modalities, and ambulation
• (AAOS) “Unable to recommend for or against a supervised or unsupervised exercise program for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Inconclusive
• (AAOS) “Unable to recommend for or against electrical stimulation for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Inconclusive
• loss of 50% of vertebral body height• angulation of thoracolumbar junction > 20 deg• multiple adjacent compression frx• failure of 2/3 of columns of spine
• spinal segment will fail with weight bearing• even w/ spinal instability ‐may have good response w/ a hyperextsion cast
• note: a brace should not be considered a substitute for a well molded hyperextension cast
• (AAOS) “We are unable to recommend for or against any specific treatment for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are not neurologically intact.” Strength of Recommendation: Inconclusive
• Not indicated• AAOS recommends strongly against the use of vertebroplasty
• Outcomes• randomized, double‐blind, placebo‐controlled trials have shown no beneficial effect of vertebroplasty
• Vertebroplasty has higher rates of cement extravasation and associated complications than kyphoplasty
• (AAOS) “Recommend against vertebroplasty for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Strong
• Indications• Patient continues to have severe pain symptoms after 6 weeks of nonoperative treatment
• Technique• Kyphoplasty is different than vertebroplasty in that a cavity is created by expansion balloon and therefore the cement can be injected with less pressure
• Pain relief thought to be from elimination of micromotion
• (AAOS) “Kyphoplasty is an option for patients who present with an osteoporotic spinal compression fracture on imaging with correlating clinical signs and symptoms and who are neurologically intact.” Strength of Recommendation: Limited
• Elective stabilization and arthrodesis should be considered
