Clinical Significance of PLIF in Restoring L4-S1 Segmental Lordosis of 2-level Isthmic Spondylolisthesis

Abstract Background: Spinal and pelvic sagittal plane balance is closely related to good clinical prognosis, so in the treatment of 2-level isthmic spondylolisthesis, attention should be paid not only to adequate nerve decompression, but also to the correction of lumbosacral sagittal plane parameters. The purpose of this study was to observe the clinical prognosis and sagittal parameters of patients with isthmic spondylolisthesis treated with PLIF, and to find out the risk factors leading to poor prognosis. Methods: From January 2006 to August 2018, the clinical data of patients with 2-level isthmic spondylolisthesis treated with PLIF in the Second Xiangya Hospital of Central South University were retrospectively collected. The clinical symptoms (JOA score and VAS score) and the sagittal parameters of lumbosacral segment (PI, PT, LL, L4-S1 SL, LDI, PI-LL, LL and L4-S1 SL) were recorded before operation, immediately after operation and at the last follow-up. According to the improvement rate of JOA score, the patients were divided into two subgroups, poor(P) group and good(G) group. The parameters within and between the two subgroups were compared. Meanwhile, Pearson correlation analysis was conducted between sagittal parameters and JOA score improvement rate.Results: A total of 52 patients were enrolled in this study, the average age was (59.96 ±9.11) years, and the mean follow-up time was (31.88 ±8.37) months. Group G (n = 37) and group P (n = 15). In terms of clinical symptom improvement and sagittal plane parameters, except PI, the other parameters of the patients were improved compared with those before operation, and the difference was statistically significant. In the intra-group comparison, except PI, other indexes in group G were significantly improved, while in group P, there was no significant difference in PI, LL, L4-S1 SL, LDI, PI-LL before and after operation. In the comparison between groups, there was no significant difference in baseline data between group G and group P; postoperative VAS score(back pain) in group G was lower than that in group P, but there was no significant difference in VAS score( leg pain); in terms of JOA score and JOA score improvement rate, group G was significantly better; △L4-S1 SL ,L4-S1 SL and LDI were larger in group G, and the proportion of patients with normal LDI was higher than that in group P. Pearson correlation analysis showed that postoperative △L4-S1 SL, LDI and L4-S1 SL were positively correlated with JOA improvement rate. 2 patients with failed internal fixation occurred in group P, and the postoperative LDI was less than 50%. Conclusion: PLIF is an effective method for the treatment of 2-level isthmic spondylolisthesis. ΔL4-S1 SL, L4-S1 SL and good LDI may be important sagittal parameters affecting the clinical prognosis of L4 and L5 isthmus spondylolisthesis.

Background: Computer Navigation in Total Knee Replacement (TKR) has completed more than a decade since its inception. From that time, numerous studies have been done to see its effect on the variables of surgery and its outcome. Some studies have shown that it is definitely beneficial while others have negated its superiority over conventional techniques. This is an early outcome study on the results of navigation TKR in terms of alignment and clinical outcome at three years post-operatively. Methods: In the present study, 128 patients who had undergone navigation TKR (128 TKR) between January 2006 and November 2009 were included. The navigation system used was orthoPilot®. Patients were assessed post-operatively at one and three year using knee society score (KSS) and knee function score (KFS). All patients completed one year follow-up and 55 patients completed three year follow-up. From 128 patients, 40 navigated TKR patients operated between November 2007 and 2009 and were compared with 40 patients operated by conventional TKR operated between July 2007 and December 2008. Results: The mean KSS at 1 year post-operatively was 85.60 and at 3 years was 85.87. The mean KFS at 1 year post-operatively was 69.30 and at 3 years was 68.00. There was no statistically significant difference between navigation TKR and conventional TKR in terms of anatomical femoro-tibial alignment, femoral component alignment in coronal and sagittal plane and tibial component alignment in coronal plane. However, there was statistically significant difference between tibial component alignment in sagittal plane (p = 0.000) between both the groups. Conclusion: Computer navigation TKR affords a possibility to place both the femoral and tibial component very precisely without the risk of any greater axis deviation from ideal value. It helps in reducing the outliers in alignment of the limb and that of component and that improves the overall implant survival for a long time post-operatively.

ABSTRACTPlantar fasciitis is a disorder caused by inflammation of the insertion point of the plantar fascia over the medial tubercle of the calcaneus. Foot orthotics are used to treat plantar fasciitis. Heel pads medialise the centre of force, whereas medial arch supporting insoles lateralise the force. We assessed the clinical results of the treatment of plantar fasciitis with silicone heel pads and medial arch-supported silicone insoles.We retrospectively reviewed 75 patients with heel pain. A total of 35 patients in the first group were treated with medial arch supporting insoles, and 40 patients in the second group were treated with heel pads. The patients were evaluated with the Visual Analogue Scale (VAS) and the Foot and Ankle Ability Measure (FAAM) at the first and last examinations.The mean VAS score in the first group was 8.6±1,2 (6-10); the FAAM daily activity score was 66.2±16 (41.2-95.0), and the sporting activity score was 45.4±24,4 (0.1-81) before treatment. At the last follow-up in this group, the mean VAS score was 5.3±1,5 (0-9); the FAAM daily activity score was 83,0±15,1 (55,9-100), and the sporting activity score was 73,5±26,2 (25-100). The mean VAS score in the second group was 8,6±0,9 (7-10); the FAAM daily activity score was 66.4±17 (41.4-95.2), and the sporting activity score was 45.8±24,2 (0.8-81, 3) before the treatment. At the last follow-up in this group, the mean VAS score was 5.5±1,2 (0-9); the FAAM daily activity score was 83.4±14,9 (60, 2-100), and the sporting activity score was 73.8±26 (28-100).There was no significant difference in the clinical results of both groups. The force distribution by the use of silicone heel pads and medial arch-supported silicone insoles had no effect on the clinical results of the treatment of plantar fasciitis.

Category: Ankle Arthritis, Trauma Introduction/Purpose: The supination-adduction ankle fractures often showed vertical impaction of the tibial medial plafond. The malunion of these fractures cause the varus ankle deformity and secondary ankle arthritis. This retrospective control study looked at the use of supramalleolar osteotomy combined with intra-articular osteotomy in patients with malunited supination- adduction ankle fractures. Methods: Twelve patients were treated with malunited supination-adduction ankle fractures between January 2013 and December 2014. All of these patients had the varus ankle deformity and secondary ankle arthritis. Supramalleolar osteotomy combined with intra-articular osteotomy were underwent for the reconstruction surgery. The visual analog scale (VAS) score for pain during daily activities, Olerud and Molander Scale scores, subjective satisfaction survey rating and the modified Takakura classification stage were obtained. Ten patients were available for follow-up at a mean of 35.4 months (range, 28 to 40 months). Results: Average postoperative Olerud and Molander Scale score 24 months after surgery was 83±10 compared with 60±14 preoperatively. The mean VAS score decreased from 7±2 preoperatively to 2±2 at the latest follow-up. Six patients rated their result as excellent, 3 as good and 1 as fair. No significant difference in the modified Takakura classification stage was observed between the preoperative and the last follow-up. Conclusion: The use of supramalleolar osteotomy combined with intra-articular osteotomy was an effective option for the treatment of malunited supination-adduction ankle fractures.

Abstract Background Patients with greater tuberosity fractures of the humerus often require surgery. Therefore, there is a need to find a minimally invasive and effective surgical procedure with great patient outcomes. Aim To evaluate the clinical outcomes of the W-shaped suture technique under shoulder arthroscopy in the treatment of greater tuberosity fractures of the humerus. Methods In this retrospective study, a total of 17 patients were included. The fractures were closed, and there was no neurovascular injury. These patients underwent arthroscopically assisted reduction and internal fixation of the greater tuberosity fractures. Fixation was performed using sighting nails combined with a W-shaped suture. The imaging data of the patients were collected, and the ASES score, Constant-Murley score, and VAS score were used to evaluate the patient’s outcome. At the last follow-up (at least 1 year), the range of motion in the affected shoulder was compared with that of the contralateral side. Results The operation was successful in all the patients. The average follow-up time was 13 months. There were no reported complications such as fracture displacement, nonunion, and internal fixation failure during the follow-up period. Post-operative X-ray examinations revealed good function recovery, with a healing time of between 10 and 12 weeks, and an average healing time of 11.5 weeks. Following the operation, patients reported reduced shoulder joint pain that no longer influenced their activity or caused discomfort in their daily life. The patient’s VAS score ranged from 0 to 3, with an average of 0.52 ± 0.73, while at the last follow-up, the Constant-Murley score ranged from 83 to 97, with an average of 92.33 ± 7.55. The ASES score ranged from 81 to 98, with an average of 93.15 ± 6.93. At the last follow-up, there was no significant difference in the overall range of motion with the unaffected limb. Conclusion This study demonstrates that the W-shaped suture can be used to effectively fix the fractures of the greater tuberosity of the humerus, by increasing the fixed area to promote healing.

Abstract Background: To investigate the treatment effect of minimally invasive treatment of early osteonecrosis of femoral head (ONFH) with hydroxyapatite coated hollow titanium rod. Methods: From 1, January 2003 to 1, January 2019, 72 patients with ONFHⅡ Stage were selected. There were 50 males and 20 females, aged from 28 to 56. Onset time was 8~28 months. Lesion site: 18 left, 38 right, 16 bilateral. Causes of ONFH: 30 alcohol, 28 hormone, 9 trauma and 5 idiopathic patients. ARCO stage: 14 IIA, 33 IIB, 25 IIC. All patients underwent arthroscopic assisted minimally invasive percutaneous core decompression and bone grafting with hydroxyapatite coated titanium rod surgery. Visua Analogue Scales (VAS), Harris score and Images were used for assessing pain, hip joint function and the stability, respectively. Hip replacement was performed finally. Results: 16 patients with heavy hormone use history and femoral head collapse underwent Total Hip Resurfacing Arthroplasty (THRA) at the last follow-up. 24 months later, 8 ⅡB cases progressed to ⅡC, 2 cases were stable at ⅡC, 6 cases increased to Ⅲ, and underwent THRA. 12ⅡC cases progressed to Ⅲ, 2 cases were stable at Ⅲ, and 10 cases had articular cartilage surface collapse. THRA was administered 30 months after surgery. VAS score of individual patients increased and Harris score decreased 24 months after surgery, but there was no significant difference between the scores of 12 months and 24 months. The clinical effect of the last follow-up showed that the postoperative improvement rate of this group was 76.13%, among which the best was 100% in IIA, 79.48% in IIB, and the lowest was 58.06 in IIC. Both the patients with IIB or IIC, cases with aggravation and without change were hormonal ONFH. Conclusion: The treatment of ONFH with hydroxyapatite coated hollow titanium rod supporting the femoral head to prevent collapse is feasible. In addition to the Glucocorticoid-induced ONFH stage ⅡC outside, this method to other Ⅱ period lesions in improving the curative effect and preventing the collapse of femoral head articular surface is good and safe.

Abstract INTRODUCTION Anterior Column Reconstruction (ACR) is an increasingly utilized minimally invasive alternative to Pedicle Subtraction Osteotomy (PSO) for correction of sagittal plane deformity in patients with an available unfused lumbar disc. METHODS Fifteen consecutive patients with significant sagittal plane imbalance (SVA > 10 cm or PI-LL mismatch/planned correction > 30?) after prior lumbar fusion were analyzed. Patients underwent either an ACR (N = 11) using an expandable, hyperlordotic lateral interbody device if possible via an unfused disc space, or PSO (n = 4). RESULTS There were no significant differences between the baseline sagittal parameters in the ACR and PSO groups: PI: 59.09? vs 57.67?, P = .88; LL 18.36? vs 28.50?, P = .38; PT: 32.72? vs 37.00?, P = .64; SVA: 12.72 cm vs 11.95 cm P = .77; segmental angulation 2.72? vs 2.75?, P = .99. ACR produced significant improvements in sagittal parameters after surgery compared with preoperative parameters: LL 55.27?, P = .0001; Pi-LL Mismatch 3.45?, P = .0001; PT 22.45?, P = .0254; SVA 4.621 cm P = .0019; segmental angle 25.09?, P < .0001. PSO also produced significant segmental lordosis (29.00?, P = .0032), which was not significantly different from the correction achieved by ACR (25.09? vs 29.00?, P = .47). In ACR, an average of 24.31? of lordosis was achieved at the index level, with an average cage expansion of 24.08?. There was no significant difference in the number of levels fused posteriorly between the ACR and PSO groups (7 vs 8.75 levels, P = .175) or length of surgery (375.25 min vs 370.5 min, P = .47). However, there was significantly less blood loss in the ACR group (311.15 mL vs 962.5 mL, P = .0004) and shorter length of stay (7.41 d vs 11 d, P = .034). CONCLUSION ACR with a hyperlordotic, expandable lateral interbody cage for significant sagittal deformity produced an equivalent degree of sagittal correction to PSO with significantly less blood loss and shorter hospital length of stay.

Abstract Background To explore the clinical effect of laminectomy alone and laminectomy with instrumentation in the treatment of TOLF. Methods A retrospective study was conducted on the clinical data of 142 patients with TOLF and laminectomy who underwent spine surgery at XXX Medical University from January 2003 to January 2018. According to whether the laminectomy was combined with instrumentation, the patients were divided into two groups: group A (laminectomy alone (LA), n = 77) and group B (laminectomy with instrumentation (LI), n = 65). Comparisons of possible influencing factors of demographic variables and operation-related variables were carried out between the two groups. In this study, the clinical effects of LA and LI in the treatment of TOLF were discussed. Thus, we explored the clinical effect of LA and LI in the treatment of TOLF. Results In terms of demographics, there was a statistically significant difference in BMI between group A and group B (P < 0.05). The differences in age, sex, smoking, drinking, heart disease, hypertension and diabetes were not statistically significant (P > 0.05). In terms of preoperative symptoms, there was a significant difference in gait disturbance, pain in the LE, and urination disorder between group A and group B (P < 0.05), but there was no significant difference in other variables between the two groups (P > 0.05). In terms of operation-related variables, there was a significant difference in the preoperative duration of symptoms, intramedullary signal change on MRI, dural ossification, residual rate of cross-sectional spinal canal area on CT, shape on the sagittal MRI, operation time, pre-mJOA, post-mJOA at 1 year, and leakage of cerebrospinal fluid between group A and group B (P < 0.05), but there was no significant difference in other variables between the two groups (P > 0.05). The preoperative average JOA score of group A was 6.37 and that of group B was 5.19. In group A, the average JOA score at 6 months, 1 year and 2 years after surgery was 7.87, 8.23 and 8.26, respectively, and the average JOA score improvement rate was 32.79 %, 38.32 and 38.53 %, respectively. In group B, the average JOA score at 6 months, 1 year and 2 years after surgery was 7.74, 8.15 and 8.29, respectively, and the average JOA score improvement rate was 39.15 %, 46.86 and 47.12 %, respectively. Conclusions Currently, there is no consensus on whether instrumentation is needed after laminectomy for TOLF. We found that for patients with a long duration of gait disturbance, urination disorder, preoperative duration of symptoms, intramedullary signal change on MRI, dural ossification, residual rate of cross-sectional spinal canal area on CT less than 60 %, and shape on the sagittal MRI being beak and low, pre-mJOA had better clinical effects after LI as compared to those after LA, and the incidence of perioperative complications was lower.

Abstract Background Purely ligamentous Lisfranc injuries are mainly caused by low energy damage and often require surgical treatment. There are several operative techniques for rigid fixation to solve this problem clinically. This study evaluated the effect of using the Tightrope system to reconstruct the Lisfranc ligament for elastic fixation. Methods We retrospectively analyzed 11 cases with purely ligamentous Lisfranc injuries treated with the Tightrope system from 2016 to 2019, including 8 male and 3 female. X-ray was performed regularly after operation to measure the distance between the first and second metatarsal joint and the visual analogue scale (VAS) score was used to evaluate pain relief. American orthopedic foot & ankle society (AOFAS) and Maryland foot score were recorded at the last follow-up. Results The average follow-up time was 20.5 months (range, 17–24). There was statistically significant difference in the distance between the first and second metatarsal joint and VAS score at 3 months, 6 months, and the last follow-up when compared with preoperative values (P < 0.05).Mean of postoperative AOFAS mid-foot scale and Maryland foot score were 92.4 ± 4.3, 94.1 ± 3.5, respectively. The Tightrope system was not removed and the foot obtained better biomechanical stability. No complications occurred during the operation. Conclusion Tightrope system in the treatment of purely ligamentous Lisfranc injuries can stabilize the tarsometatarsal joint and achieve satisfactory effect.

Abstract Background: To analyze the effect of different types of bone cement distribution after percutaneous vertebroplasty (PVP) in patients with osteoporotic vertebral compression fracture (OVCF). Methods: 137 patients with single level OVCF who underwent PVP were retrospectively analyzed. The patients were divided into two groups according to bone cement distribution. Group A: bone cement contacted both upper and lower endplates; Group B: bone cement missed at least one endplate. Group B was divided into 3 subgroups. Group B1: bone cement only contacted the upper endplates; Group B2: bone cement only contacted the lower endplates; Group B3: bone cement only located in the middle of vertebral body. The visual analogue scale (VAS) score at 24 hours post operation and last follow-up, anterior vertebral height restoration ratio (AVHRR), anterior vertebral height loss ratio (AVHLR), local kyphotic angle change and vertebral body recompression rate were compared. Results: 24 hours post operation, the pain of all groups were significantly improved. The average follow-up time was 15.3 ± 6.3 (6-24) months. At last follow-up, the VAS score of group A was lower than that of group B. There were 14 cases (10.2%) of adjacent vertebral fracture, 5 cases (8.6%) in group A and 9 cases (11.4%) in group B. There were 9 cases (6.6%) of cement leakage, 4 cases (6.9%) in group A and 5 cases (6.3%) in group B. At last follow-up, there were 16 cases (11.7%) of vertebral body recompression, including 3 cases (5.2%) in group A and 13 cases (16.5%) in group B. There was no significant difference in AVHRR between two groups. Local kyphotic angle change was significant larger in group B. At last follow-up, AVHLR in group B was higher than that in group A. In subgroup analysis, there was no significant difference in VAS score, local kyphotic angle change, vertebral recompression rate, AVHRR or AVHLR. Conclusions: If the bone cement fully contacted both the upper and lower endplates, it can better restore the strength of the vertebral body and maintain the height of the vertebral body, reduce the risk of the vertebral body recompression and long-term pain.

Objectives. To explore the influencing factors of satisfaction with postoperative treatment in patients diagnosed with thoracic ossification of the ligamentum flavum during different follow-up periods. Methods. This was a retrospective study of 57 patients who were diagnosed with thoracic ossification of ligamentum flavum (TOLF) and treated with laminectomy in the Spine Surgery Department of the Third Hospital of Hebei Medical University from January 2010 to January 2017. The Patient Satisfaction Index (PSI) was collected at discharge and at 6-month, 1-year, and the last follow-up. According to the evaluation results, the patients could be divided into a satisfied group and a dissatisfied group. The patient’s Japanese Orthopaedic Association (JOA) score improvement rate was evaluated at the last follow-up. Possible influencing factors of the two groups of patients were compared and the related influencing factors of satisfaction with postoperative treatment in patients during different follow-up periods were summarized. Results. At the time of discharge, the dissatisfied and satisfied groups had significant differences in variables of diabetes mellitus, duration of preoperative symptoms, urination disorder, intramedullary signal change on MRI, dural ossification, residual rate of cross-sectional spinal canal area on CT, shape on the sagittal MRI, hospital stay, hospitalization expenses, postoperative pain in LE VAS, delayed wound healing, postoperative depression, and intercostal pain ( P < 0.05 ). There were also significant differences in urination disorder, postoperative pain according to the LE VAS, JOA score, and postoperative depression during the 6-month follow-up ( P < 0.05 ). There were no significant differences in other variables between the two groups ( P > 0.05 ). One year after the operation, there were significant differences between the dissatisfied group and the satisfied group in urination disorder, JOA score, and symptom recurrence ( P < 0.05 ). There were also significant differences in the JOA score and symptom recurrence at the final follow-up ( P < 0.05 ). For further analysis, the duration of preoperative symptoms in the satisfied group was less than 24 months and the duration of preoperative symptoms in the dissatisfied group was more than 24 months. The JOA scores of patients in the satisfied group and the dissatisfied group increased gradually with the improvement of neurological function in different follow-up periods, but, at the last follow-up, the JOA scores of patients in the satisfied group were significantly higher than those in the dissatisfied group. Conclusions. In conclusion, for thoracic ossification of ligamentum flavum patients who received laminectomy, dissatisfaction with the early and medium-term postoperative results may be related to diabetes, the duration of preoperative symptoms, hospitalization expenses, delayed wound healing, intercostal pain, and urination disorder, and dissatisfaction with the long-term postoperative results might be related to the low JOA score improvement rate and symptom recurrence.
