Abstract BACKGROUND Lateral (ie, coronal) vertebral listhesis may contribute to disability in adult scoliosis patients. OBJECTIVE To assess for a correlation between lateral listhesis and disability among patients with adult scoliosis. METHODS This was a retrospective multi-center analysis of prospectively collected data. Patients eligible for a minimum of 2-yr follow-up and with coronal plane deformity (defined as maximum Cobb angle ≥20º) were included (n = 724). Outcome measures were Oswestry Disability Index (ODI) and leg pain numeric scale rating. Lateral thoracolumbar listhesis was measured as the maximum vertebral listhesis as a percent of the superior endplate across T1-L5 levels. Linear and logistic regression was utilized, as appropriate. Multivariable analyses adjusted for demographics, comorbidities, surgical invasiveness, maximum Cobb angle, and T1-PA. Minimally clinically important difference (MCID) in ODI was defined as 12.8. RESULTS In total, 724 adult patients were assessed. The mean baseline maximum lateral thoracolumbar listhesis was 18.3% (standard deviation 9.7%). The optimal statistical grouping for lateral listhesis was empirically determined to be none/mild (<6.7%), moderate (6.7-15.4%), and severe (≥15.4%). In multivariable analysis, listhesis of moderate and severe vs none/mild was associated with worse baseline ODI (none/mild = 33.7; moderate = 41.6; severe = 43.9; P < .001 for both comparisons) and leg pain NSR (none/mild = 2.9, moderate = 4.0, severe = 5.1, P < .05). Resolution of severe lateral listhesis to none/mild was independently associated with increased likelihood of reaching MCID in ODI at 2 yr postoperatively (odds ratio 2.1 95% confidence interval 1.2–3.7, P = .0097). CONCLUSION Lateral thoracolumbar listhesis is associated with worse baseline disability among adult scoliosis patients. Resolution of severe lateral listhesis following deformity correction was independently associated with increased likelihood of reaching MCID in ODI at 2-yr follow-up.

Objective To compare two different approaches for the treatment of lumbosacral tuberculosis. Patients and Methods In total, 115 patients who were surgically treated in our department from July 2010 to July 2014 were included in this retrospective study. They were divided into the anterior and posterior approach groups. Intraoperative hemorrhage; the surgery time; the Cobb angle preoperatively, postoperatively, and at the follow-up visit (2 years postoperatively); visual analog scale (VAS) pain scores before and after surgery; and Oswestry Disability Index (ODI) scores before and after surgery were compared between the two groups. Results The Cobb angle and VAS and ODI scores were significantly improved in both groups after surgery. Significant differences were found in the operation time, intraoperative hemorrhage, Cobb angle correction, and loss of correction at the last follow-up. No significant differences were found in the VAS and ODI scores between the groups. Conclusions The posterior approach is superior to the anterior approach with respect to the surgery time, intraoperative hemorrhage, and Cobb angle postoperatively and at the last follow-up. When both approaches can be carried out for a patient with lumbosacral tuberculosis, the posterior approach should be favored over the anterior approach.

OBJECTIVE Lateral interbody fusion (LIF) with percutaneous screw fixation can treat adult spinal deformity (ASD) in the coronal plane, but sagittal correction is limited. The authors combined LIF with open posterior (OP) surgery using facet osteotomies and a rod-cantilever technique to enhance lumbar lordosis (LL). It is unclear how this hybrid strategy compares to OP surgery alone. The goal of this study was to evaluate the combination of LIF and OP surgery (LIF+OP) for ASD. METHODS All thoracolumbar ASD cases from 2009 to 2014 were reviewed. Patients with < 6 months follow-up, prior fusion, severe sagittal imbalance (sagittal vertical axis > 200 mm or pelvic incidence-LL > 40°), and those undergoing anterior lumbar interbody fusion were excluded. Deformity correction, complications, and outcomes were compared between LIF+OP and OP-only surgery patients. RESULTS LIF+OP (n = 32) and OP-only patients (n = 60) had similar baseline features and posterior fusion levels. On average, 3.8 LIFs were performed. Patients who underwent LIF+OP had less blood loss (1129 vs 1833 ml, p = 0.016) and lower durotomy rates (0% vs 23%, p = 0.002). Patients in the LIF+OP group required less ICU care (0.7 vs 2.8 days, p < 0.001) and inpatient rehabilitation (63% vs 87%, p = 0.015). The incidence of new leg pain, numbness, or weakness was similar between groups (28% vs 22%, p = 0.609). All leg symptoms resolved within 6 months, except in 1 OP-only patient. Follow-up duration was similar (28 vs 25 months, p = 0.462). LIF+OP patients had significantly less pseudarthrosis (6% vs 27%, p = 0.026) and greater improvement in visual analog scale back pain (mean decrease 4.0 vs 1.9, p = 0.046) and Oswestry Disability Index (mean decrease 21 vs 12, p = 0.035) scores. Lumbar coronal correction was greater with LIF+OP surgery (mean [± SD] 22° ± 13° vs 14° ± 13°, p = 0.010). LL restoration was 22° ± 13°, intermediately between OP-only with facet osteotomies (11° ± 7°, p < 0.001) and pedicle subtraction osteotomy (29° ± 10°, p = 0.045). CONCLUSIONS LIF+OP is an effective strategy for ASD of moderate severity. Compared with the authors' OP-only operations, LIF+OP was associated with faster recovery, fewer complications, and greater relief of pain and disability.

Abstract Purpose Cubitus varus deformity in the pediatric population is an infrequent but clinically important disease to orthopedic surgeons. Since these patient populations are different in many respects, we sought out to investigate the rates of loss of correction over time as well as the factors associated with loss of correction in pediatric patients undergoing osteotomy for treatment of cubitus varus deformity. Methods Between 2008-7 and 2017-7, we treated 30 cases of cubital varus had underwent the the osteotomy. We compared preoperative and postoperative clinical and imaging parameters (H-cobb angle,Baumman angle) for all patients. Postoperative evaluation was performed by telephone interview.Results In our study,there were 30 patients,included 17 males and 13 females.the mean age was 75 months old.In the first follow-up,Approximately 80 % of patients had a loss of correction of H-cobb，and 83% of patients at the second follow-up. The Baumann angle also had a loss of correction,about 57% was lost at the first follow-up,and 43% was lost at the second follow-up. The average interval between the first follow-up and the second follow-up was 24 days ，The H-cobb angle mean loss was 2.4°.There was a statistically significant difference between the H-cobb angle measured before surgery and the angle measured after surgery (p <0.05). There were significant differences between the two angles. There was no statistically significant difference between the H-cobb angle measured at the third postoperative period and the contralateral healthy elbow H-cobb angle. There was a statistically significant difference between the Baumann angle measured before surgery and the angle measured after surgery (p <0.05). The Baumann angle measured in the second and third postoperative periods was significantly different from that of the contralateral healthy elbow joint. According to the survival curve analysis, we can see that the median survival time of the H-cobb angle and the Baumann angle is 27 and 34 months. Conclusions The postoperative angle loss will last for a period of time, which mainly occurs during the first and second follow-up period . Therefore, it is important to pay attention to the follow-up of the patient for a period of time after the operation, and take measures to avoid rapid angle loss. Angle loss was significantly reduced after the third follow-up. Further study is needed on this subgroup of patients with cubitus varus given the differences in strategies needed to correct and maintain their deformity correction.

Category: Ankle Arthritis Introduction/Purpose: Addressing coronal plane deformity when performing a total ankle arthroplasty (TAA) remains a topic of controversy. While surgeons have become bolder in correcting deformity, long-term follow-up is sparse regarding maintenance of correction and viability of the prosthesis. The purpose of this study is to assess the long-term follow up of the correction of moderate to severe coronal plane deformity with the use of a mobile bearing prosthesis. Methods: Out of a consecutive series of 130 patients who underwent TAA between 2000 and 2009, 43 patients (44 ankles) had at least 100 of tibiotalar coronal plane deformity, with 25 having between 100 and 200 of deformity and 18 having greater than 200. Average age at time of the index surgery was 66 yrs (range 41-79). Initial deformity was 17.90 (range 10-290) in the entire cohort. All patients underwent intraarticular deformity correction with intraoperative soft-tissue balancing as indicated utilizing the STAR prosthesis. Patients requiring realignment osteotomies were performed in a staged fashion prior to undergoing TAA. Results: Seven patients (16%) were available for long-term follow up (avg 13 yrs; range 9-16 yrs) with retention of the original prosthesis, two of which had greater than 200 of initial deformity. Average final tibiotalar deformity was 4.90, with a mean correction of 130(p=0.0001). No additional procedures related to the prosthesis were performed. Eleven patients (12 ankles) were deceased at the time of the study due to unrelated conditions. Of the original cohort, five were deemed failures (2 converted to arthrodesis; 2 underwent component revision; 1 polyethylene fracture) and excluded from long-term follow up. The remaining 20 patients were lost to follow-up, had declined or were unable to participate due to health status. Conclusion: While the low follow-up rate limits the overall generalizability of the results, enduring correction of moderate and severe coronal plane deformity with a mobile bearing prosthesis can be achieved in a cohort of patients traditionally regarded as high-risk. One must be cautious when discussing with patients the utilization of TAA in the setting of moderate and severe coronal plane deformity given the risk of failure. However, provided a well-balanced ankle can be achieved intraoperatively, long-term mobile bearing prosthesis survivorship is achievable.

Object Few options exist for the treatment of severe, early onset scoliosis. Goals of treatment include stabilizing curve progression while allowing for normal spine, chest, and lung growth. The vertical expandable prosthetic titanium rib (VEPTR) is a novel device designed to control the spine deformity while permitting lung and spine growth. In this paper the authors report their experience with using bilateral VEPTRs from the ribs to the pelvis for children with severe, early onset scoliosis. Methods Eleven children were identified who had been treated with bilateral VEPTRs from the ribs to the pelvis. The authors conducted a retrospective review and collected the following data: clinical diagnosis, age at surgery, number of lengthening procedures, and complications. In addition, pre- and postoperative radiographs were reviewed to measure maximum Cobb angle (both thoracic and lumbar), thoracic height, total spine height as measured from T-1 to S-1, thoracic kyphosis (T2–12), and lumbar lordosis (L1–S1). Results The average patient age at surgery was 71 months; the mean preoperative thoracic Cobb angle was 81.7°. This angle was corrected to 50.6° immediately postoperatively, and this correction was maintained; at the most recent follow-up the curves averaged 58°. Similarly, the preoperative kyphosis (T2–12) angle measured 43° preoperatively, 23° immediately postoperatively, and 37° at the most recent follow-up evaluation. The patients underwent a total of 41 lengthening procedures (average 3.7 lengthening procedures per patient), and overall spine length increased from 23.1 cm preoperatively, to 27.3 cm immediately postoperatively, to 29.4 cm at the final follow-up (an average of 25 months). Four (36.4%) of the 11 patients experienced complications. Conclusions The VEPTR offers a viable treatment option for children with severe, early onset scoliosis. It achieves and maintains spinal deformity correction, while allowing for continued spine and chest-wall growth. Complication rates are similar to those reported for other growing systems.

Abstract INTRODUCTION The fractional curve in adult scoliosis often causes radiculopathy and may be managed in varied manners with minimally invasive (MIS) deformity correction. There are inherent risks and benefits to anterior and posterior interbody reconstruction techniques, and the purpose of this study was to evaluate for differences in outcomes or complication rates by fractional curve treatment via MIS anterior vs. posterior interbody fusion METHODS Inclusion criteria were age = 18 yr, and one of the following: coronal cobb > 20°, SVA > 5 cm, PT > 20°, PI-LL > 10°. Patients were treated with circumferential MIS (cMIS) surgery or hybrid MIS surgery and had 2-yr minimum follow-up. Patient were divided into two groups: anterior or posterior interbody fusion at the lumbosacral junction (L4-S1). HRQOL measures included Oswestry Disability Index (ODI), visual analog score (VAS). RESULTS A total of 112 patients who underwent MIS adult deformity surgery with minimum 2-yr follow up. A total of 74 patients underwent anterior and 38 patients underwent posterior interbody reconstruction at L4-S1 utilizing MIS technique. Preoperative spinopelvic parameters, radiographic parameters, and VAS were not different, but ODI was higher in the anterior group (53 vs 48, P = .047). Complications and reoperation rates were not different (P = .089, P = .597), but posterior had more infections (15.8% vs 2.7%, P = .01). When subdivided for cMIS only surgery, 38 had anterior and 19 underwent posterior interbody fusions in the fractional curve. Pre- and postoperative VAS leg, ODI, and fractional curve magnitude were not different. In the anterior surgery cohorts, laminectomies at L4-S1 were performed in 22% of hybrid cases and in 8% of cMIS cases. CONCLUSION Treatment of the fractional curve of adult scoliosis appears to be similarly effective in reducing VAS, ODI, and fractional curve magnitude regardless of anterior vs posterior approach. However, posterior interbody reconstruction was associated with higher infection rate than anterior, regardless of application in cMIS or hybrid technique.

Aims Magnetically controlled growing rods (MCGR) have been gaining popularity in the management of early-onset scoliosis (EOS) over the past decade. We present our experience with the first 44 MCGR consecutive cases treated at our institution. Methods This is a retrospective review of consecutive cases of MCGR performed in our institution between 2012 and 2018. This cohort consisted of 44 children (25 females and 19 males), with a mean age of 7.9 years (3.7 to 13.6). There were 41 primary cases and three revisions from other rod systems. The majority (38 children) had dual rods. The group represents a mixed aetiology including idiopathic (20), neuromuscular (13), syndromic (9), and congenital (2). The mean follow-up was 4.1 years, with a minimum of two years. Nine children graduated to definitive fusion. We evaluated radiological parameters of deformity correction (Cobb angle), and spinal growth (T1-T12 and T1-S1 heights), as well as complications during the course of treatment. Results The mean Cobb angles pre-operatively, postoperatively, and at last follow-up were 70° (53 to 103), 35° (15 to 71) and 39° (15 to 65) respectively (p < 0.001). Further, there was a mean of 14° (-6 to 27) of additional Cobb angle correction upon graduation from MCGR to definitive fusion. Both T1-T12 and T1-S1 showed significant increase in heights of 27 mm and 45 mm respectively at last follow-up (p < 0.001). Ten children (23%) developed 18 complications requiring 21 unplanned operations. Independent risk factors for developing a complication were single rod constructs and previous revision surgery. Conclusion MCGR has the benefit of avoiding multiple surgeries, and is an effective tool in treatment of early-onset scoliosis. It also maintains the flexibility of the spine, allowing further correction at the time of definitive fusion. Cite this article: Bone Joint Open 2020;1-7:405–414.

Abstract Spinal deformity management can be difficult. The decision for surgery, approach, number of levels, and surgical technique all present challenges. Even when other issues are managed appropriately the process of how to correct the deformity needs special consideration. Numerous techniques have been studied including vertebra-to-rod, rod de-rotation, 3-rod-techniques, and cantilever maneuvers. While cantilever is the preferred technique when treating sagittal plane deformity, scoliosis often requires a combination of techniques due to the complexity of deformity in coronal and transverse planes. This video illustrates an adult scoliosis correction using sequential reduction towers and de-rotation techniques. Using this method the step of hook holders is eliminated and tension is distributed evenly across the rod using sequential reduction of the reduction towers across the length of the rod. This has led to a very efficient correction of our deformity as well as a powerful de-rotation tool. We routinely use this technique for flexible and rigid deformities, which is assessed pre-op with a computed tomography. The patient is a 67-yr-old female with prior lumbar decompressions and worsening back pain with radiculopathy. No significant sagittal malalignment is present but pelvic tilt is elevated and a coronal deformity exists. pelvic incidence measures 59°, LL50°, PT28° and lumbar scoliosis shows a coronal Cobb angle of 50.8°. Briefly, surgery involved transpedicular instrumentation from T10-S1 with bilateral iliac screw fixation. To achieve mobility posterior column osteotomies were performed at T12-L1, L1-2, L2-3, L3-4, L4-5, and L5-S1 levels. TLIF was performed at L4-5, L5-S1 for fusion. Postoperative scoliosis X-rays demonstrated improved sagittal and coronal alignment with PI59°, LL59°, PT22°, and coronal Cobb angle of 12°.

Study Design: Retrospective study. Objectives: This study retrospectively evaluates the outcome of the surgical treatment of early-onset scoliosis with proximal clawing rib fixation in hybrid growing-rod constructs. The study examines spinal deformity correction with spinal growth maintenance, and the complications associated with this technique. Method: A hybrid rib construct surgery with serial lengthening was utilized for the treatment of 71 patients. Mean age at surgery was 66.6 months and mean time for follow-up was 43.9 months. Results: The coronal Cobb angle in patients fell from 63.1° preoperatively to 51.6° at the last follow-up, with a correction of 16.8%. The sagittal Cobb angle fell from 66.7° preoperatively to 38° at the last follow-up, with a correction of 42.6%. Coronal balance fell from 22.8° preoperatively to 22.3°, and sagittal balance fell from 35.4 mm preoperatively to 24.39 mm. T1-S1 spine height increased from 248.7 mm preoperatively to 282.4 mm, with a mean change of 1.13 cm per year. No neurological complications were detected. Conclusion: Surgical management for early-onset scoliosis using proximal clawing rib fixation technique is a good choice in terms of safety, ease of placing the proximal anchors, ability to use more than one form of instrumentation, and a lower complication rate.
