of atypical femoral fractures is a known complication of chronic bisphosphonate therapy; however, the finding of atraumatic lumbar pedicle fractures without a prior history of spinal surgery or contralateral spondylolysis is rare. While a few cases of osteoporotic pedicle fractures associated with adjacent vertebral compression fractures have been reported, only a single case of isolated atraumatic bilateral pedicle fractures has been published in a patient who had been on chronic risedronate therapy of 10-year duration. Case Report: The present case report illustrates a 63-year-old man who developed isolated atraumatic bilateral lumbar pedicle fractures after 3 years and 5 months on alendronate treatment. The patient’s past medical history had been significant for osteoporosis with a lumbar spine T-score of -2.7. At the time of initial diagnosis, a comprehensive work-up for secondary causes of osteoporosis proved to be negative; this was followed by initiation of bisphosphonate treatment with 70 mg of alendronate once per week. Ten months after starting bisphosphonate therapy, he underwent magnetic resonance imaging (MRI) of the lumbar spine for low back pain that had not responded to conservative management, with imaging not revealing any evidence of pedicle fractures or pedicle stress reaction. He was again seen in the spine clinic, for atraumatic exacerbation of his chronic low back pain with concurrent right lower extremity radiation, 6 months after stopping bisphosphonate therapy. Since the patient failed to respond to conservative management over the ensuing 6 months, a repeat MRI was obtained, which showed new acute/subacute bilateral L5 pedicle fractures. Conclusion: An isolated atraumatic lumbar pedicle fracture may be an additional type of atypical fracture associated with chronic bisphosphonate therapy in an osteoporotic patient. Key words: Chronic low back pain, bisphosphonate, alendronate, pedicle fracture Pain Medicine

Context: Reduced spinal stabilization, delayed onset of muscle activation, and increased knee joint stiffness have been reported in individuals with a history of low back pain (LBP). Biomechanical adaptations resulting from LBP may increase the risk for future injury due to suboptimal loading of the lower-extremity or lumbar spine. Assessing landing mechanics in these individuals could help identify which structures might be susceptible to future injury. Objective: To compare vertical and joint stiffness of the lower-extremity and lumbar spine between individuals with and without a previous history of LBP. Design: Cross-sectional study. Setting: Research laboratory. Participants: There were 45 participants (24 without a previous history of LBP—age 23 [8] y, height 169.0 [8.5] cm, mass 69.8 [13.8] kg; 21 with a previous history of LBP—age 25[9] y, height 170.0 [8.0] cm, mass 70.2 [11.8] kg). Interventions: Single-limb landing trials on the dominant and nondominant limb from a 30-cm box. Main Outcome Measures: Vertical stiffness and joint stiffness of the ankle, knee, hip, and lumbar spine. Results: Individuals with a previous history of LBP had lower vertical stiffness (P = .04), but not joint stiffness measures compared with those without a previous history of LBP (P > .05). Overall females had lower vertical (P = .01), ankle (P = .02), and hip stiffness (P = .04) compared with males among all participants. Males with a previous history of LBP had lower vertical stiffness compared with males without a previous history LBP (P = .01). Among all individuals without a previous history of LBP, females had lower vertical (P < .01) and ankle stiffness measures (P = .04) compared with males. Conclusions: Landing stiffness may differ among males and females and a previous history of LBP. Comparisons between individuals with and without previous LBP should be considered when assessing landing strategies, and future research should focus on how LBP impacts landing mechanics.

Introduction. Low back pain (LBP) is common in children and adolescents. There are many factors that cause LBP, including structural disorders, degenerative changes, Scheuermann’s disease, fractures, inflammation, and tumors. Magnetic Resonance Imaging is the gold standard for diagnosing spinal abnormalities and is mandatory when neurological symptoms exist. The study focuses on common MRI findings in adolescents with persistent LBP, without history of acute trauma or evidence of either inflammatory or rheumatic disease. Materials and Methods. Eleven adolescents were submitted to thoracic and/or lumbar spine MRI due to persistent LBP. The protocol consisted of T1 WI, T2 WI, and T2 WI with FS, in the axial, sagittal, and coronal plane. Results. MRI revealed structural abnormalities (scoliosis and kyphosis) in 4/11 (36.36%); disc abnormalities and endplate changes were found on 11/11 (100%). Typical Scheuermann’s disease was found in 3/11 (27.27%). Endplate changes were severe in Scheuermann’s patients and mild to moderate in the remaining 8/11 (72.72%). Kyphosis was in all cases secondary to Scheuermann’s disease. Disk bulges and hernias were found in 8/11 (72.72%), all located in the lumbar spine. Conclusion. In adolescents with LBP, structural spinal disorders, degenerative changes, and Scheuermann’s disease are commonly found on MRI; however, degenerative changes prevail.

Abstract Context: Isolated lumbar paraspinal muscle fatigue causes lower extremity and postural control deficits. Objective: To describe the change in body position during gait after fatiguing lumbar extension exercises in persons with recurrent episodes of low back pain compared with healthy controls. Design: Case-control study. Setting: Motion analysis laboratory. Patients or Other Participants: Twenty-five recreationally active participants with a history of recurrent episodes of low back pain, matched by sex, height, and mass with 25 healthy controls. Intervention(s): We measured 3-dimensional lower extremity and trunk kinematics before and after fatiguing isometric lumbar paraspinal exercise. Main Outcome Measure(s): Measurements were taken while participants jogged on a custom-built treadmill surrounded by a 10-camera motion analysis system. Results: Group-by-time interactions were observed for lumbar lordosis and trunk angles (P &lt; .05). A reduced lumbar spine extension angle was noted, reflecting a loss of lordosis and an increase in trunk flexion angle, indicating increased forward trunk lean, in healthy controls after fatiguing lumbar extension exercise. In contrast, persons with a history of recurrent low back pain exhibited a slight increase in spine extension, indicating a slightly more lordotic position of the lumbar spine, and a decrease in trunk flexion angles after fatiguing exercise. Regardless of group, participants experienced, on average, greater peak hip extension after lumbar paraspinal fatigue. Conclusions: Small differences in response may represent a necessary adaptation used by persons with recurrent low back pain to preserve gait function by stabilizing the spine and preventing inappropriate trunk and lumbar spine positioning.

AbstractThe purpose of this study was to examine the influence of a history of low back pain (LBP) on pelvic and lumbar kinematics during baseball hitting. Twenty collegiate male baseball players (age, 21±1 years; height, 172.8±4.7 cm; weight, 72.7±6.2 kg; baseball experience, 13±1 years) performed 5 bat swings. Participants were categorized into the LBP group (n=10) or control group (n=10) based on having experienced lumbar spine pain due to bat swing that lasted more than 24 h within the last 12 months. Three-dimensional kinematic data of the pelvis and lumbar spine during bat swing were measured. Two-way ANOVAs were used to compare pelvic and lumbar kinematics throughout the bat swing between groups, and independent t-tests were used to compare the other outcomes between groups. There was a significant main effect between groups in lumbar flexion angle throughout the bat swing (p=0.047). The mean lumbar flexion angle of the LBP group throughout the bat swing was less than that of the control group. Additionally, the peak angular velocity of lumbar flexion of the LBP group was significantly faster than that of control group (p=0.047). These results can be helpful for longitudinal studies that identify the risk factors of LBP due to bat swing.

ObjectivesTo investigate (1) self-reported societal comprehension of common and usually non-serious terms found in lumbar spine imaging reports and (2) its relationship to perceived seriousness, likely persistence of low back pain (LBP), fear of movement, back beliefs and history and intensity of LBP.DesignCross-sectional online survey of the general public.SettingFive English-speaking countries: UK, USA, Canada, New Zealand and Australia.ParticipantsAdults (age >18 years) with or without a history of LBP recruited in April 2019 with quotas for country, age and gender.Primary and secondary outcome measuresSelf-reported understanding of 14 terms (annular fissure, disc bulge, disc degeneration, disc extrusion, disc height loss, disc protrusion, disc signal loss, facet joint degeneration, high intensity zone, mild canal stenosis, Modic changes, nerve root contact, spondylolisthesis and spondylosis) commonly found in lumbar spine imaging reports. For each term, we also elicited worry about its seriousness, and whether its presence would indicate pain persistence and prompt fear of movement.ResultsFrom 774 responses, we included 677 (87.5%) with complete and valid responses. 577 (85%) participants had a current or past history of LBP of whom 251 (44%) had received lumbar spine imaging. Self-reported understanding of all terms was poor. At best, 235 (35%) reported understanding the term ‘disc degeneration’, while only 71 (10.5%) reported understanding the term ‘Modic changes’. For all terms, a moderate to large proportion of participants (range 59%–71%), considered they indicated a serious back problem, that pain might persist (range 52%–71%) and they would be fearful of movement (range 42%–57%).ConclusionCommon and usually non-serious terms in lumbar spine imaging reports are poorly understood by the general population and may contribute to the burden of LBP.Trial registration numberACTRN12619000545167.
