Abstract

Key Points Question Does early surgical treatment yield better motor recovery than delayed surgical treatment for patients with preexisting cervical canal stenosis sustaining acute traumatic spinal cord injury? Findings In this randomized clinical trial that included 72 patients with motor-incomplete cervical spinal cord injury, there was no statistically significant difference between groups in mean improvement in American Spinal Injury Association motor score, total score in the spinal cord independence measure, or patients’ ability to walk at 1 year. Early surgical treatment was associated with higher motor scores than delayed surgical treatment in the first 6 months. Meaning These findings suggest that among patients with motor-incomplete cervical spinal cord injury, early surgical treatment did not significantly improve motor recovery at 1 year compared with delayed surgical treatment but showed accelerated recovery., This randomized clinical trial assesses motor recovery outcomes in early vs delayed surgical treatment for patients with acute traumatic incomplete cervical spinal cord injury associated with preexisting canal stenosis., Importance The optimal management for acute traumatic cervical spinal cord injury (SCI) is unknown. Objective To determine whether early surgical decompression results in better motor recovery than delayed surgical treatment in patients with acute traumatic incomplete cervical SCI associated with preexisting canal stenosis but without bone injury. Design, Setting, and Participants This multicenter randomized clinical trial was conducted in 43 tertiary referral centers in Japan from December 2011 through November 2019. Patients aged 20 to 79 years with motor-incomplete cervical SCI with preexisting canal stenosis (American Spinal Injury Association [ASIA] Impairment Scale C; without fracture or dislocation) were included. Data were analyzed from September to November 2020. Interventions Patients were randomized to undergo surgical treatment within 24 hours after admission or delayed surgical treatment after at least 2 weeks of conservative treatment. Main Outcomes and Measures The primary end points were improvement in the mean ASIA motor score, total score of the spinal cord independence measure, and the proportion of patients able to walk independently at 1 year after injury. Results Among 72 randomized patients, 70 patients (mean [SD] age, 65.1 [9.4] years; age range, 41-79 years; 5 [7%] women and 65 [93%] men) were included in the full analysis population (37 patients assigned to early surgical treatment and 33 patients assigned to delayed surgical treatment). Of these, 56 patients (80%) had data available for at least 1 primary outcome at 1 year. There was no significant difference among primary end points for the early surgical treatment group compared with the delayed surgical treatment group (mean [SD] change in ASIA motor score, 53.7 [14.7] vs 48.5 [19.1]; difference, 5.2; 95% CI, −4.2 to 14.5; P = .27; mean [SD] SCIM total score, 77.9 [22.7] vs 71.3 [27.3]; P = .34; able to walk independently, 21 of 30 patients [70.0%] vs 16 of 26 patients [61.5%]; P = .51). A mixed-design analysis of variance revealed a significant difference in the mean change in ASIA motor scores between the groups (F1,49 = 4.80; P = .03). The early surgical treatment group, compared with the delayed surgical treatment group, had greater motor scores than the delayed surgical treatment group at 2 weeks (mean [SD] score, 34.2 [18.8] vs 18.9 [20.9]), 3 months (mean [SD] score, 49.1 [15.1] vs 37.2 [20.9]), and 6 months (mean [SD] score, 51.5 [13.9] vs 41.3 [23.4]) after injury. Adverse events were common in both groups (eg, worsening of paralysis, 6 patients vs 6 patients; death, 3 patients vs 3 patients). Conclusions and Relevance These findings suggest that among patients with cervical SCI, early surgical treatment produced similar motor regain at 1 year after injury as delayed surgical treatment but showed accelerated recovery within the first 6 months. These exploratory results suggest that early surgical treatment leads to faster neurological recovery, which requires further validation.

Abstract

Background: The radiographic outcomes of nonoperative treatment of dropped head syndrome are still unknown. The purpose of the present study was to assess the change in sagittal spinopelvic radiographic parameters after the short and intensive rehabilitation (SHAiR) program in patients with dropped head syndrome., Methods: This study included 48 consecutive patients with dropped head syndrome who presented with an inability to maintain horizontal gaze and who underwent the SHAiR program during the period of 2018 to 2019. Patients were divided into 2 groups according to their ability to maintain horizontal gaze at the time of final follow-up: those who had regained horizontal gaze (the "effective" group) and those who had not regained horizontal gaze (the "noneffective" group). Sagittal radiographic parameters including the sagittal vertical axis (SVA), the C2-7 angle, the C2-7 SVA, T1 slope, thoracic kyphosis of T1-5 and T5-12, lumbar lordosis, pelvic tilt, pelvic incidence, sacral slope, and curve flexibility, and demographic data and clinical outcomes were compared between the 2 groups using an unpaired t test, chi-square test, and Fisher exact test, as appropriate., Results: Thirty-five patients in the effective group and 13 patients in the noneffective group were analyzed. The rate of response in regaining horizontal gaze with the SHAiR program was 73%. The C2-7 angle, the C2-7 SVA, T1 slope, and thoracic kyphosis (T1-5) demonstrated significant correction in the effective group (p < 0.05). There were no significant changes in other parameters below the mid-thoracic spine-i.e., the thoracolumbar and lumbar spine and pelvis-following the SHAiR program. Scores of the Neck Disability Index and visual analog scale for pain improved significantly in both groups., Conclusions: The SHAiR program improved horizontal gaze among a large percentage of our patients and reduced cervical pain among patients overall. The correction of thoracic kyphosis (T1-5) might be an important treatment target to restore the appropriate T1 tilt in patients with dropped head syndrome., Level of Evidence: Therapeutic Level III.

Abstract

Purpose: The purpose of this study was to evaluate the feasibility and safety of percutaneous vertebroplasty (PVP) using single-plane C-arm fluoroscopy., Materials and Methods: Lesions in the present study all comprised compression fractures with intact pedicles. A polymethylmethacrylate (PMMA) mixture was injected by the transpedicular approach under C-arm fluoroscopy using a lateral projection. Before and after PVP, the pain score was determined using visual analog scale methods., Results: Between June 2002 and May 2004, we performed 31 PVPs in 17 patients during 22 treatment sessions. Underlying pathology comprised neoplasm-related compression fracture (n=9) and fractures attributed to osteoporosis (n=8). Mean pain score was 8.0 (range, 4.5-10) immediately before PVP, and 1.9 (range, 0-7) at 24 h after PVP. Mean time needed to perform PVP was 59 min. Mean time to approach a pedicle was 36 min (range, 20 min for 1 pedicle to 110 min for 3 pedicles). No complications requiring surgical intervention or exacerbating conditions beyond pre-treatment levels were noted., Conclusion: PVP using single-plane C-arm fluoroscopy for guidance is feasible, safe, and quick.
