Abstract PurposeTo compare the efficacy and safety of percutaneous short-segment pedicle screws fixation (PPSF) with or without intermediate screws (IS) for the treatment of thoracolumbar compression fractures.MethodsFrom January 2016 to March 2019, a retrospective study of 38 patients with thoracolumbar compression fractures conducted. The patients were divided into a 4-screw group (without IS) and a 6-screw group (with IS) according to whether pedicle screws were placed in the fractured vertebrae. Combined positional reduction effects with the technique of pre-contoured lordotic rods were used to reduce the fracture by lengthening the anterior column of the fractured vertebrae. The posterior structure of the fractured vertebrae was undertaken as the fulcrum point for both groups. The operation time, intra-operative blood loss, visual analogue scale (VAS), anterior vertebral body height (AVBH), segment kyphosis（SK）before and after operation and complications were recorded.ResultsAlthough the operation time and blood loss in the 6-screw group were higher than in the 4-screw group, difference was not significant (P＞0.05). There was no significant difference in VAS, AVBH and SK between the two groups (P＞0.05). Nevertheless, these results were significant differences between the preoperative and the immediate postoperative, between preoperative and follow-up groups (P < 0.001). No neurologic injury was observed in either groups. ConclusionsIn the treatment of thoracolumbar compression fractures, percutaneous short-segment pedicle screws fixation without intermediate screws in the 4-screw construct may obtain the same clinical effect as that in the 6-screw construct.

Object The main aim of this study was to compare clinical and radiological outcomes after stabilization by a percutaneous transpedicular system and stabilization from the standard open approach for thoracolumbar spine injury. Methods Thirty-seven consecutive patients were enrolled in the study over a period of 16 months. Patients were included in the study if they experienced 1 thoracolumbar fracture (A3.1–A3.3, according to the AO/Magerl classification), had an absence of neurological deficits, had no other significant injuries, and were willing to participate. Eighteen patients were treated by short-segment, minimally invasive, percutaneous pedicle screw instrumentation. The control group was composed of 19 patients who were stabilized using a short-segment transpedicular construct, which was performed through a standard midline incision. The pain profile was assessed by a visual analog scale (VAS), and overall satisfaction by a simple 4-stage scale relating to performance of daily activities. Working ability and return to original occupation were also monitored. Radiographic follow-up was defined by the vertebral body index (VBI), vertebral body angle (VBA), and bisegmental Cobb angle. The accuracy of screw placement was examined using CT. Results The mean surgical duration in the percutaneous screw group was 53 ± 10 minutes, compared with 60 ± 9 minutes in the control group (p = 0.032). The percutaneous screw group had a significantly lower perioperative blood loss of 56 ± 17 ml, compared with 331 ± 149 ml in the control group (p < 0.001). Scores on the VAS in patients in the percutaneous screw group during the first 7 postoperative days were significantly lower than those in the control group (p < 0.001). There was no significant difference between groups in VBI, VBA, and Cobb angle values during follow-up. There was no significant difference in screw placement accuracy between the groups and no patients required surgical revision. There was no significant difference between groups in overall satisfaction at the 2-year follow-up (p = 0.402). Working ability was insignificantly better in the percutaneous screw group; previous working position was achieved in 17 patients in this group and in 12 cases in the control group (p = 0.088). Conclusions This study confirms that the percutaneous transpedicular screw technique represents a viable option in the treatment of preselected thoracolumbar fractures. A significant reduction in blood loss, postoperative pain, and surgical time were the main advantages associated with this minimally invasive technique. Clinical, functional, and radiological results were at least the same as those achieved using the open technique after a 2-year follow-up. The short-term benefits of the percutaneous transpedicular screw technique are apparent, and long-term results have to be studied in other well-designed studies evaluating the theoretical benefit of the percutaneous technique and assessing whether the results of the latter are as durable as the ones achieved by open surgery.

Abstract Background The open-door laminoplasty is an effective procedure for the treatment of cervical spondylotic myelopathy. However, little information is available about the surgical results of open-door laminoplasty in the treatment of intraspinal tumors. In the present study, we aimed to investigate the clinical effect of open-door laminoplasty with ARCH plate fixation in the treatment of cervical intraspinal tumors. Methods This was a retrospective study. From January 2013 to May 2018, 38 patients (13 males and 25 females, the average age of 44 ± 17 years) with cervical intraspinal tumors underwent open-door laminoplasty with ARCH plate fixation in our hospital. The operation time, blood loss, pre- and postoperative visual analog scale (VAS), and Japanese Orthopedic Association (JOA) scores were determined. To determine the radiographic outcomes, cervical X-ray film and magnetic resonance imaging (MRI) were performed before and after the operation, and cervical X-ray sagittal film was used to measure Cobb angle. The clinical data before and after the operation were compared by t-test. Results A total of 38 patients underwent a successful operation and demonstrated primary healing. The average operation time was 113 ± 12 min. The average blood loss was 120 ± 19 mL. All patients were followed up for 26.1 ± 2.8 months, and the final follow-up time was more than 24 months. VAS scores were much better at 24 months after operation compared with those before the operation, which were decreased from 6.1 ± 1.1 to 1.4 ± 0.7 (t = 32.63, P < 0.01). The JOA score was improved from 9.9 ± 1.5 to 15.5 ± 0.6 (t = − 18.36, P < 0.01), and the mean JOA recovery rate was 79% ± 11% at 24 months after the operation. There was no significant difference in Cobb angle between pre-operation and 24 months after the operation, which was 9.8 ± 2.6 and 10.3 ± 3.1 respectively (t = − 0.61, P > 0.05). Neither spinal malalignment on the coronal plane nor displacement of the laminoplasty flap was observed on postoperative cervical X-ray and MRI examinations at the final follow-up. Conclusions Open-door laminoplasty with ARCH plate fixation was a safe and effective surgical approach for the treatment of cervical intraspinal tumors.

Short Segment Fixation

Abstract Objective: The most prevailing surgical procedure in the treatment of thoracolumbar burst fractures, Short Segment Fixation (SSF), is often followed by loss of correction or hardware failure which may be significant enough to require another surgical intervention. In order to take advantage of its benefits but to avoid or diminish the risk and impact of associated drawbacks, some other alternatives have been lately developed among which we refer to short segment fixation with intermediate screws (SSF+IS). This article provides a comparative picture over the effectiveness of the two above-mentioned surgical treatments, focusing on their potential to prevent the loss of correction. Methods: After a systematic literature review over research papers published between 2000 and 2012, 14 articles which met the criteria were included in the meta-analysis. The relevant data extracted and compared for each subgroup of patients treated either with SSF or SSF+IS, were the weighted averages for the pre-operative, post-operative and last follow up kyphosis angles. We also considered common associated complications, operation time, and blood loss values for each surgical subgroups. Results: The values for the loss of correction at the last follow-up were: 5.5° for SS and 7.4° for SSF+IS, which didn’t prove to be statistically different. With reference to other parameters, such as operation time, blood loss and correction attainment, the values did not present statistically significant differences, either. Regarding complications, we noticed that both SSF and SSF+IS display a similar incidence for hardware failure, screw breakages, superficial infections, deep venous thrombosis. Conclusions: This paper concludes that, adding one or two screws at the fractured vertebra level (SSF+IS) does not bring forth a significant improvement compared to the traditional approach (SSF). Apparently, the blood loss depends mostly on the approach type (open or percutaneous) and less on the surgery type.

Tibial Shaft Fractures

Abstract Background: Tibial shaft fractures are routinely managed with intramedullary nailing (IMN). An increasingly accepted technique is the suprapatellar (SP) approach. The purpose of this study was to compare the clinical and functional outcomes of knee joint after tibia IMN through an suprapatellar (SP) or traditional infrapatellar (IP) approach. Methods: Retrospective analysis was performed in patients with tibial shaft fractures that were treated with IMN through a SP or IP approach between 01/01/2014 and 31/12/2016. The clinical and functional outcomes of the knee were assessed with the Hospital for Special Surgery (HSS) Knee Score. Secondary outcomes included the operation time and intraoperative blood loss. Results: A total of 50 patients/fractures (26 IP and 24 SP) with a minimum follow-up of 15 months were evaluated. All fractures were OTA 42. No significant differences were found between the two groups in age, gender, side of fractures, operation time, intra-operative blood loss, and follow-up time. No significant difference was seen in HSS score ( P = 0.62) between them. Sub analysis of all the HSS components scores revealed no significant differences between pain ( P = 0.57), the stand and walk ( P = 0.54), the need for walking stick ( P = 0.60) and extension lag ( P = 0.60). The other HSS components showed full scores (IP 10 vs. SP 10) in both approaches, including muscle force, flexion deformity and stability components. The range of motion (ROM) component score was superior in the IP group ( P = 0.04) suggesting a higher ROM. Conclusions: Both SP and IP approach results in equivalent overall HSS knee scores. However, for the HSS component, the IP approach was superior to SP approach regarding the ROM.

OBJECTIVE The aim of this paper was to compare the radiographic and clinical outcomes between the sequential correction (SC) technique and the traditional 2-rod correction (TC) technique in patients with severe thoracic idiopathic scoliosis (STIS) undergoing posterior-only correction surgery. METHODS Records of a consecutive series of STIS patients undergoing posterior-only correction surgery between October 2013 and October 2017 with more than 2 years of follow-up were reviewed. The radiographic parameters were assessed preoperatively, postoperatively, and at the last follow-up. Radiographic parameters, operative time, blood loss, and complications were compared between the two groups. RESULTS A total of 33 patients were included in the SC group, and 21 patients were included in the TC group. There was no significant difference in age, sex, or deformity magnitude (93.6° ± 7.8° vs 89.8° ± 6.6°, p = 0.070) preoperatively between groups. The operation time was shorter in the SC group than in the TC group (251.5 ± 42.8 minutes vs 275.4 ± 39.8 minutes, p = 0.020), while both blood loss (1284.6 ± 483.3 vs 1398.0 ± 558.4 ml, p = 0.432) and number of fused levels (13.1 ± 2.8 vs 13.6 ± 2.4, p = 0.503) were similar between the groups. Compared with the TC group, patients in the SC group had a higher correction rate (55.8% ± 9.2% vs 45.7% ± 8.8%, p < 0.001), less coronal (1.1° ± 0.81° vs 2.9° ± 0.93°, p < 0.001) and sagittal (1.5° ± 0.96° vs 2.1° ± 0.64°, p = 0.015) correction loss at the 2-year follow-up, and a lower incidence of intraoperative pedicle screw pullout (14.3% vs 23.8%, p = 0.026). CONCLUSIONS The SC technique could significantly and practically reduce the difficulty of rod installation with better deformity correction outcomes than the traditional TC technique. The SC technique was an effective alternative for patients with STIS.

Aim. Comparing the clinical results of improved monosegment pedicle instrumentation (iMSPI) and short-segment pedicle instrumentation (SSPI) retrospectively.Method. 63 patients with thoracolumbar incomplete burst fracture were managed with iMSPI or SSPI. 30 patients were managed with iMSPI and fusion. 33 patients were managed with SSPI and fusion. Operative time, blood loss, postoperative drainage, and complications were recorded. Percentage of anterior body height compression (ABHC%) and sagittal index (SI) were obtained preoperatively, one week postoperatively, and at the last followup.Results. The blood loss and postoperative drainage were significantly less in the iMSPI group than in SSPI group(P<0.05). The follow-up duration of the two groups was not significantly different(P>0.05). At 12 months postoperatively posterolateral fusion was obtained satisfactorily. Neither preoperative ABHC% and SI nor postoperative SI were significantly different(P>0.05), but there was a significant difference in postoperative ABHC%(P=0.000). The ABHC% and SI were not significantly different between the two groups at the last followup(P>0.05). There were no fixation failures or other complications.Summary. IMSPI yielded satisfactory results similar to those of SSPI in patients with type A3.1/3.2 thoracolumbar fractures. IMSPI is recommended for minor trauma, reducing one-segment fusion, and maximization of the remaining motor function.

Abstract BackgroundThis is a retrospective study to evaluate the efficacy of percutaneous short segment fixation (PSSF) with or without intermediate screws in Magerl A3 thoracolumbar (TL) fractures accompanied with low bone mineral density (BMD).Methods From January 2017 to December 2018, 30 patients diagnosed with Magerl A3 TL fractures having a BMD between 0.5/cm2 and 1g/cm2 in the lumbar vertebrae with intact neurological functions and a history of major trauma who underwent PSSF with or without intermediate screws were enrolled in this study. The patients were divided into two groups of those with intermediate screws (group F) or without (group S). The operation time and intra-operation blood loss were recorded. Oswestry disability index (ODI) questionnaire and visual analogue scale (VAS) were employed as clinical assessments and quantified. Radiographic follow-up assessed according to the Cobb angle (CA), Vertebral wedge angle (VWA), and anterior vertebral body height (AVBH).ResultsLoose screws were observed in 4 of the 30 enrolled patients. Significant differences were observed in operation time and intra-operative blood loss between the two groups. The enrolled patients’ clinical results (VAS and ODI scores) were good, however, no significant differences during all follow-up periods were present between the two groups. Radiographic evaluation (CA, VWA and AVBH) improved immediately after surgery, but significant correction loss was observed in the follow-up periods, especially in the first month. Radiographic evaluation demonstrated no significant differences between the two groups.Conclusion Although the patients’ clinical results were satisfactory, PSSF could not resist the correction loss in Magerl A3 TL fractures accompanied with BMD below 1g/cm2. Accordingly, the use of intermediate pedicle screws may be unnecessary due to their limited ability in resisting correction loss and increasing operation time as well as intra-operation blood loss.

Background: Previous studies have reported a high incidence of re-collapse of the augmented vertebrae after percutaneous vertebral augmentation (PVA) for osteoporotic vertebral compression fractures (OVCFs) with intravertebral vacuum cleft (IVC) during long-term followup. Previous IVC might be considered an important predisposing factor for re-collapse, but the prior studies could not find a significant correlation. Objective: To determine the incidence and distribution characteristics of IVCs and to further assess IVCs in their varied locations. To assess the long-term therapeutic efficacy of PVA for OVCFs with IVC. Study Design: A retrospective cohort study. Setting: Department of spinal surgery, an affiliated hospital of a medical university. Methods: A retrospective review was performed on 594 patients who underwent PVA to treat OVCFs from January 2010 to December 2013. Eighty-two patients with the IVC sign were enrolled in the study. The follow-up period was a minimum of 2 years. The difference between IVC and non-IVC patients was compared. Comparisons of the radiological and clinical findings at varied IVC locations were made pre-operatively and post-operatively (immediate, at one year, and at 2 years). Results: IVC incidence correlated with older patient age and severe demineralization. Other baseline parameters showed no significant differences. The rate of cement leakage and vertebral fracture was significantly lower in the IVC groups than in the non-IVC groups intraoperatively. There was no significant difference in the incidence of cement leakage or adjacent vertebral fractures between the 3 IVC groups. In the immediate postoperative period, all patients benefited from significant improvement in vertebral body height and kyphotic angle correction. However, significant re-collapse was observed at the 2-year post-operative followup for the IVC patients when compared to the non-IVC patients. Among the 3 IVC groups, the most severe re-collapse was observed with inferior endplate IVCs. Superior endplate IVCs and IVCs extending to both endplates demonstrated only mild re-collapse at the 2-year follow-up. Limitation: Due to the infrequency of this process, the number of patients with IVCs was small. Conclusion: PVA treatment was initially effective in all patients with OVCFs. However, significant re-collapse of the augmented vertebrae with IVCs, especially those with inferior endplate IVCs, was found with long-term follow-up.

This study aims to investigate the efficacy of posterior short-segment pedicle instrumentation without fusion in curing thoracolumbar burst fracture. All of the 53 patients were treated with short-segment pedicle instrumentation and laminectomy without fusion, and the restoration of retropulsed bone fragments was conducted by a novel custom-designed repositor (RRBF). The mean operation time and blood loss during surgery were analyzed; the radiological index and neurological status were compared before and after the operation. The mean operation time was 93 min (range: 62–110 min) and the mean intraoperative blood loss was 452 mL in all cases. The average canal encroachment was 50.04% and 10.92% prior to the surgery and at last followup, respectively (P<0.01). The preoperative kyphotic angle was 17.2 degree (±6.87 degrees), whereas it decreased to 8.42 degree (±4.99 degrees) at last followup (P<0.01). Besides, the mean vertebral body height increased from 40.15% (±9.40%) before surgery to 72.34% (±12.32%) at last followup (P<0.01). 45 patients showed 1-2 grades improvement in Frankel’s scale at last followup. This technique allows for satisfactory canal clearance and restoration of vertebral body height and kyphotic angle, and it may promote the recovery of neurological function. However, further research is still necessary to confirm the efficacy of this treatment.
