Abstract Background: Pre-existing degeneration of adjacent segment is an important risk factor for adjacent segment degeneration (ASD), but limited and controversial studies have addressed its management.Methods: Patients with symptomatic degeneration of the L5/S1 segment warranting surgical interference and severe asymptomatic degeneration of the L4/5 segment were retrospectively analyzed. Among them, those who underwent interbody fusion in the causative (L5/S1) segment and distraction of the intervertebral space and facet fusion in the adjacent L4/5 segment were included as Group A (n=103). Patients who underwent interbody fusion in both L5/S1 and L4/5 segments were included as Group B (n=81). Clinical and radiographic outcomes were evaluated.Results: Mean follow-up was 58.5 months (range, 48-75 m). No significant difference in clinical outcomes or the incidence of adjacent segment degeneration in L3/4 segment was found between Groups A and B. Compared with Group B, less bleeding (315±84 vs. 532±105 ml), shorter operation time (107±34 vs. 158±55 min) and lower costs (13,830±2640 vs. 16,020±3380 US$) were found in Group A (P<0.05). In Group A, disc height ratio (DHR) of L4/5 segment was significantly increased from preoperative value of 0.40±0.13 to last follow-up value of 0.53±0.18 (P<0.05), while the degree of canal stenosis (DCS) was decreased from preoperative value of 34.3±11.2% to last follow-up value of 15.9±9.3% (P<0.05). Conclusions: This modified method could be effective in treating severe asymptomatic pre-existing degeneration of adjacent segment in lumbar spine.

Abstract Background Pre-existing degeneration of adjacent segment is an important risk factor for adjacent-segment degeneration (ASD), but only limited and controversial studies have addressed its management. Methods We retrospectively analyzed patients with symptomatic degeneration of the L5/S1 segment warranting surgical interference and severe asymptomatic degeneration of the L4/5 segment. Of these patients, those who underwent interbody fusion of the causative (L5/S1) segment and distraction of the intervertebral space and facet fusion of the adjacent L4/5 segment were included in Group A (n = 103), while those who underwent interbody fusion of both the L5/S1 and L4/5 segments were included in Group B (n = 81). Clinical and radiographic outcomes were evaluated. Results Mean follow-up time was 58.5 months (range, 48–75 months). We found no significant difference in clinical outcomes or incidence of ASD in the L3/4 segment between Groups A and B. Compared with Group B, Group A experienced less bleeding (315 ± 84 ml vs. 532 ± 105 ml), shorter operation time (107 ± 34 min vs. 158 ± 55 min) and lower costs (US $13,830 ± $2640 vs. US $16,020 ± $3380; P < 0.05). In Group A, the disc height ratio (DHR) of the L4/5 segment was significantly increased from a preoperative value of 0.40 ± 0.13 to a last–follow-up value of 0.53 ± 0.18 (P < 0.05), while the degree of canal stenosis (DCS) was decreased from a preoperative value of 34.3 ± 11.2% to a last–follow-up value of 15.9 ± 9.3 % (P < 0.05). Conclusions This modified method could be effective in treating severe asymptomatic pre-existing degeneration of adjacent segment in the lumbar spine.

Abstract Objective To explore the clinical efficacy and radioactive results of the bridge-type ROI-C interbody fusion cage (ROI-C) and anterior cervical discectomy and fusion with plating and cage system (ACDF) for cervical spondylopathy. Methods From January 2014 to January 2018, 45 patients undergoing ACDF were retrospectively analyzed, including 24 cases of ROI-C (group A) and 21 cases of ACDF (group B). The operation time, blood loss, Neck Disability Index (NDI), Japanese Orthopaedic Association score (JOA), postoperative complications, imaging results including cervical Cobb angle and fusion were compared between groups. Results All patients were successfully treated with surgery, and no cerebrospinal fluid leakage, esophageal fistula, or hoarseness occurred after surgery. The operation time and blood loss in group A were lower than those in group B (P < 0.05). During the follow-up period, JOA score increased and NDI score decreased after operation (P < 0.05), but there was no significant difference between the groups (P > 0.05). The incidence of dysphagia in group A was lower than that in group B at 1 month and 3 months after operation (P < 0.05), but the final follow-up results showed that there was no significant difference in the incidence of dysphagia between the two groups (P > 0.05). In group A, the fusion rate was 83.3% 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 12.5%. In group B, the fusion rate was 85.7% 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 23.8%. Conclusion Both ROI-C and ACDF can achieve satisfactory results, but ROI-C has shorter operation time, less bleeding and lower incidence of dysphagia in the short term.

Objective. To evaluate the efficacy of suture anchor combined with double-pulley technique for subpatellar comminuted fractures compared with wire vertical suture and Krachow in the treatment of subpatellar fractures. Methods. Retrospectively selected 48 patients with subpatellar pole comminuted fracture admitted in our hospital from February 2013 to July 2019, 25 patients with double-pulley technique (group A), and 23 patients with vertical wire suture with Krachow suture. Patient age, gender, AT/OTA typing, injury mechanism, follow-up time, surgical time, bleeding volume, mean fracture healing time, and postoperative complications were recorded. The Insall-Salvati index immediately and 6 weeks after surgery. Bostman scores and knee activity were recorded at each follow-up, and month 12 was taken as the final result. Results. Time of surgery in group A (46.52 min) was significantly shorter than in group B (76.30 min). Intraoperative bleeding in group 15.1 ml, B, group 15.9 ml. Both incisions healed in stage I, averaging clinical healing of patella fracture within 10 weeks. There was no significant difference in mean Bostman score and knee activity at month 12 (group A: 28.4, 124.8°; group B: 28.1, 125.7°). There was no significant statistical difference in the Insall-Salvati index immediately or 6 weeks between the two groups. Group B patients had two wire fractures, fracture healing and the wire removed one year after surgery, and the remaining patients had no complications such as internal fixation loosening, fracture, delayed healing, or nonhealing of fracture. Conclusion. Compared with the treatment of subpatellar fracture with wire vertical suture and Krachow method, suture anchor with double-pulley technique has short operation time, reliable fixation, and less complications. Patients can have early functional exercise and good knee function recovery without secondary surgery. It can be considered as an alternative therapy for this fracture and deserves clinical adoption and promotion.

Purpose: To investigate the clinical outcomes of Visian implantable collamer lens (ICL) implantation according to lens size and implantation angle. Setting: Onnuri Smile Eye Clinic, Seoul, Republic of Korea. Design: Retrospective case series. Methods: This study included 566 eyes of 283 patients treated with ICL implantation. Patients were divided into three groups: horizontally implanted same-sized ICL (group A), horizontally implanted different sized-ICL (group B: large ICL and small ICL) and same sized-ICL implanted with a different implantation angle (group C: horizontal and vertical). Results: At 12-month follow-up, the mean vault was 0.78 ± 17, 0.48 ± 0.13, 0.71 ± 0.18 and 0.44 ± 0.16 mm when large and small sized ICL was used in group B ( p < 0.001), and when ICL was horizontally and vertically implanted in group C ( p = 0.021), respectively. And the mean SE was −0.11 ± 0.30, −0.34 ± 0.42, −0.3 ± 0.56 and −0.64 ± 0.66 dioptres (D), when the large and the small sized ICL was used group B ( p = 0.039), and when the ICL was horizontally and vertically implanted in group C ( p = 0.036), respectively. No significant difference in UDVA, IOP and ECD between both eyes in groups B and C was observed. No statistical difference was found in the vault between both eyes for groups B and C. Conclusions: The vault was significantly higher and the SE was significantly more hyperopic when a larger-sized ICL was used or the ICL was horizontally implanted compared to when the ICL was vertically implanted.

Objective:  To determine the chances of adjacent segment disease (ASD) and risk factors after posterior lumbar interbody fusion (PLIF). Material and Methods: 110 patients of both genders with degenerative lumbar instability at L4/5 level were included in my study. We did PLIF in all our patients and followed our patients for one year. The following parameters were measured: the degree of lumbar lordosis, the degree lumbosacral angle, the disc space height and their dynamic angulation and the displacement of L3 over L4. We checked the outcome with the help of the Japanese orthopedic association (JOA) and Oswestry disability index (ODI). We divided the patients into groups A and B; group A includes patients with progression of degeneration at the proximal level (L3-L4), while group B with no progression of disease at proximal level. Results:  The 86 patients (78.18%) were in group A, and 24 patients (21.88%) were in group B. There were no significant difference in radiological parameters of both groups; lumbosacral angle of lordosis, L3 laminar inclination angle, preoperative degenerative changes at proximal level, L4–L5 lordosis and BMD before surgery. The clinically and statistically significant differenceswere of the age of the patients falling in two groups. We found that at the completion of study ODI and JOA were not significantly different in both groups (P >0.05). Conclusion:  Degenerative lumbar disease is an age related disease with no significant effect of radiological degenerations on the final outcome of our patients.No other possible risk factor has a significant effect on outcome.

The operation time, blood loss, Neck Disability Index (NDI), Japanese Orthopaedic Association score (JOA), postoperative complications, imaging results including cervical Cobb angle, and fusion were compared between groups.Results: All patients were successfully treated with surgery. No cerebrospinal fluid leakage, esophageal fistula, or hoarseness occurred after the surgery. The operation time and blood loss in group A were lower than those in group B (P<0.05). During the follow-up period, JOA score increased and NDI score decreased after the operation (P<0.05), but no significant difference was found between the groups (P>0.05). In group A, the incidence of postoperative dysphagia was 12.5%, which returned to normal after 1 month. In group B, the incidence of postoperative dysphagia was 38.1%, which was 19% after 1 month and 4.8% at the final follow-up. In group A, the fusion rate was 83.3% at 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 12.5%. In group B, the fusion rate was 85.7% at 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 23.8%.Conclusion: Both ROI-C and ACDF achieved satisfactory results, but ROI-C had a shorter operation time, less bleeding, and lower incidence of dysphagia in the short term.

Abstract Purpose: To compare the efficacy, safety, and technical characteristics of anterior-only and posterior-only approach surgeries for the treatment of consecutive multisegment thoracic and lumbar tuberculosis.Methods: Thirty-five patients who developed consecutive multisegment thoracic and lumbar tuberculosis from September 2012 to May 2016 were retrospectively analyzed. Group A was the posterior-only surgery group, and group B was the anterior-only surgery group. The data on the surgery, deformity correction, functional scores and complications were compared between the two groups.Results: There was no significant difference in the operation time or blood loss between groups A and B (P>0.05). The preoperative average Cobb angle of kyphosis in groups A and B were 36.2±15.2° and 27.9±7.7°, respectively, which significantly decreased to 4.9±11.8° and 10.4±5.6° after the operation, respectively (P<0.05). At the final follow-up, the angles were 7.1±10.5° and 14.6±8.0°, respectively. The correction angle and correction rate in group A (31.3±16.6°, 88.6±43.6%) were greater than those in group B (17.5±4.4°, 64.9±14.0%) (P<0.05). There was no significant difference in the loss angle between groups A and B (P>0.05), but the loss rate in group B (24.0±27.8%) was higher than that in group A (9.6±10.2%) (P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Conclusion: The posterior-only and anterior-only approaches can lead to satisfactory clinical results in the treatment of patients with consecutive multisegment thoracic and lumbar tuberculosis. With posterior-only surgery, kyphosis can be better corrected, and the correction can be better maintained than with anterior-only surgery.
