Abstract Background Nowadays, percutaneous endoscopic lumbar discectomy (PELD) has become a popular surgical option for the management of LDH, On the basis of the approach to the herniation disc materials, PELD could be classified into percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID). During PETD procedure, especially in in-and-out approach, accurate determination of whether the posterior longitudinal ligament is needed resection seems particularly important.In the study, we tried assessing comparative clinical outcome, surgical duration and complications between the two different surgical methods of LDH treated by PETD via inside-and-out approach. Methods A total of 135 symptomatic LDH patients who were treated by PETD resecting the posterior longitudinal ligament (68 patients) or remaining the posterior longitudinal ligament (67 patients) during the surgery were included in the study. Visual analog scale (VAS) score, Oswestry disability index (ODI) and modified MacNab criteria were used to evaluate clinical outcomes. Operation time, blood loss, recurrence of LDH and other complication such as dural tear, nerve injury, intervertebral infection, etc. of these two groups were recorded. Clinical evaluation was performed preoperatively, immediately postoperatively, and at each follow-up visit (1 month, 3 months, and final follow-up). Results There were 38 males and 30 females in the group A that resecting the posterior longitudinal ligament (mean age = 52.40 ± 8.73 years) and 35 males and 32 females in the group B that remaining the posterior longitudinal ligament (mean age = 53.50 ± 9.24 years). The mean operation time of the group A and the group B respectively, were 82.7 ± 18.5 min and 115.6 ± 24.6 min (P < 0.01). The postoperative VAS scores and ODI were significantly higher than those before surgery in two groups (P < 0.01). The differences in the results were not significant between the two groups (P > 0.05). There was no significant difference in the complication rate, the excellent/good ratio and the recurrence rate between the two groups (P > 0.05). Conclusion Whether the posterior longitudinal ligament is resected do not make any difference on curative effect in PETD via inside-and-out approach, and remaining the ligament when it’s intact is preferred because of its shorter operation time.

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.

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 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.

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 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.

Abstract Background: To investigate the two different methods including bone grafting with bundled multi-segment ribs and titanium mesh bone grafting through posterior approach in patients with thoracic and lumbar spinal tuberculosis. Methods: 38 patients with thoracic spinal tuberculosis in our hospital were divided into group A (19 cases of titanium mesh bone grafting) and group B (19 cases of bone grafting with bundled multi-segment ribs). The transverse costal process approach was firstly initiated, then the necrotic tissue of tuberculosis lesions was removed thoroughly. Finally, titanium mesh bone grafting and bone grafting with bundled multi-segment ribs was applied, respectively. Results: The data demonstrated that 12 to 24 months of follow-up revealed that the operation time of Titanium mesh bone grafting in group A was 21.2+2.3 min, and that of bundled rib bone grafting in group B was 7.2+2.4 min. Compared to group A, the time in group B was significantly shorter. The amount of bleeding in group A not distinct from that in group B. There was no significant difference in Cobb angle. The fusion time in the two groups was similar. There was no significant difference in Oswestry dysfunction index between the two groups at the last follow-up. Conclusions: Bone grafting with bundled multi-segment ribs could stable the function quickly after thoracic tuberculosis lesion clearance, indicating as an alternative and development prospects of bone graft strategy.
