Clinical efficacy analysis of the new PRUNUS spine plate system for anterior cervical spine surgery

Abstract BACKGROUND To observed and evaluated the clinical efficacy of a new type cervical anterior screw plate system development for anterior cervical surgery. Methods 27 patients with cervical spine disease treated with new PRUNUS nail plate internal fixation were selected as observation group, and 29 patients treated with conventional cervical anterior screw fixation were selected as the control group. Cervical stability, internal fixation position and bone graft fusion were evaluated according to imaging data. The operative time, intraoperative blood loss, cervical Cobb angle, VAS scores, and JOA scores were compared between the two groups. Spinal function scores and neurological improvement rates were used to evaluate the clinical efficacy of the new PRUNUS spine plate. Results There were statistical differences in operation time and blood loss between the two groups (P<0.05). The difference in Cobb angle, JOA score and improvement rate, VAS score before and after surgery in two groups were statistically significant (P<0.05), but no significant differences between two groups (P>0.05). Conclusion The new PRUNUS spine plate system can be applied to the anterior cervical spine surgery, and its clinical efficacy was similar to the traditional cervical anterior plate. But PRUNUS simplified the operation process, especially for the osteoporosis patients.

Background: We reviewed the frequency, recognition, and management of postoperative hematomas (HT) (i.e. retropharyngeal [RFH], wound [WH], and/or spinal epidural hematomas [SEH]) following anterior cervical discectomy/fusion (ACDF), anterior corpectomy fusion (ACF), and/or anterior cervical spine surgery (ACSS). Methods: Postoperative cervical hematomas following ACDF, ACF, and ACSS ranged from 0.4% to 1.2% in a series of 11 studies involving a total of 44, 030 patients. These included; 4 single case reports, 2 small case series (6 and 30 cases), 4 larger series (758–2375 for a total of 6729 patients), an a large NSQUIP (National Surgical Quality Improvement Program ) Database involving 37,261 ACDF patients. Results: Risk factors contributing to postoperative cervical hematomas included; DISH (diffuse idiopathic skeletal hyperostosis), ossification of the posterior longitudinal ligament (OPLL), therpeutic heparin levels, longer operative times, multilevel surgery, ASA Scores of +/= 3, (American Society of Anesthesiologists), prone surgery, operative times > 4 hours, smoking, higher/lower body mass index (BMI), anemia, age >65, > medical comorbidities, and male gender. Notably, the use of drains did not prevent HT, and did not increase the infection, or reoperation rates. Conclusion: In our review of 11 studies focused on anterior cervical surgery, the incidence of postoperative hematomas ranged from 0.4 to 1.2%. Early recognition of these postoperative hemorrhages, and appropriate management (surgical/non-surgical) are critical to optimize recovery, and limit morbidity, and mortality.

OBJECTIVESymptomatic cervical spondylosis with or without radiculopathy can ground an active-duty military pilot if left untreated. Surgically treated cervical spondylosis may be a waiverable condition and allow return to flying status, but a waiver is based on expert opinion and not on recent published data. Previous studies on rates of return to active duty status following anterior cervical spine surgery have not differentiated these rates among military specialty occupations. No studies to date have documented the successful return of US military active-duty pilots who have undergone anterior cervical spine surgery with cervical fusion, disc replacement, or a combination of the two. The aim of this study was to identify the rate of return to an active duty flight status among US military pilots who had undergone anterior cervical discectomy and fusion (ACDF) or total disc replacement (TDR) for symptomatic cervical spondylosis.METHODSThe authors performed a single-center retrospective review of all active duty pilots who had undergone either ACDF or TDR at a military hospital between January 2010 and June 2017. Descriptive statistics were calculated for both groups to evaluate demographics with specific attention to preoperative flight stats, days to recommended clearance by neurosurgery, and days to return to active duty flight status.RESULTSAuthors identified a total of 812 cases of anterior cervical surgery performed between January 1, 2010, and June 1, 2017, among active duty, reserves, dependents, and Department of Defense/Veterans Affairs patients. There were 581 ACDFs and 231 TDRs. After screening for military occupation and active duty status, there were a total of 22 active duty pilots, among whom were 4 ACDFs, 17 TDRs, and 2 hybrid constructs. One patient required a second surgery. Six (27.3%) of the 22 pilots were nearing the end of their career and electively retired within a year of surgery. Of the remaining 16 pilots, 11 (68.8%) returned to active duty flying status. The average time to be released by the neurosurgeon was 128 days, and the time to return to flying was 287 days. The average follow-up period was 12.3 months.CONCLUSIONSAdhering to military service-specific waiver guidelines, military pilots may return to active duty flight status after undergoing ACDF or TDR for symptomatic cervical spondylosis.
