Objective. The objective of the study was the development of optimal, i.e simple, safe, and effective instrumentation for treatment of adolescent and adult scoliotic deformities. Material and Methods. The paper presents the results of surgical treatment in 23 patients with thoracic and thoracolumbar scoliosis with application of novel dorsal instrumentation developed at the Chair of Traumatology and Orthopaedics of the Russian University of Peoples’ Friendship. Twenty three patients at the mean age of 15.6 years (range, 11–44 years) with Grade IV thoracic and thoracolumbar scoliosis were operated on. The smallest Cobb angle of deformation was 61°, the largest – 96°. Surgical correction of scoliosis was performed with application of universal dorsal instrumentation. The follow-up period was 1 year. Results. The correction of Grade IV deformation with Cobb angle from 61 to 70° was 85.2–91.8 %; with Cobb angle from 71 to 80° was 83.8–90.5 %. The curvature from 81 to 96° was corrected by 65.6–73 % by single-stage operation. Conclusion. The suggested universal instrumentation for spine scoliosis correction is a hi-tech technique. Its advantages are the simple and safe application, good correction in three planes of deformation, the possibility of use both in children and in adults, and the absence of spine growth restriction in children.

OBJECTIVE The objective of this study was to evaluate the clinical efficacy of posterior-only surgical correction of dystrophic scoliosis in patients with neurofibromatosis Type 1 (NF1) using a multiple anchor point method (MAPM). METHODS From 2005 to 2014, 31 patients (mean age 13.5 years old, range 10–22 years old) suffering from dystrophic scoliosis associated with NF1 underwent posterior-only surgical correction using a MAPM. The apex of the deformity was thoracic (n = 25), thoracolumbar (n = 4), and lumbar (n = 2). The mean preoperative coronal Cobb angle was 69.1° (range 48.9°–91.4°). The mean Cobb angle on the side-bending radiograph of the convex side was 58.2° (range 40°–79.8°). The mean flexibility and apical vertebral rotation (AVR) were 15.6% (range 8.3%–28.2%) and 2.5° (range 2°–3°), respectively. The mean angle of sagittal kyphosis was 58.3° (range 34.1°–79.6°). RESULTS The mean follow-up period was 53 months (range 12–96 months). The mean postoperative coronal Cobb angle was 27.4° (range 16.3°–46.7°). Postoperatively, the mean AVR and angle of sagittal kyphosis were 1.2° (range 1°–2°) and 22.4° (range 4.2°–36.3°), respectively. All patients showed good correction of all indices postoperatively. The mean postoperative correction rate was 58.7% (range 46.3%–74.1%). At the final follow-up evaluation, the corrective loss rate of the Cobb angle was only 2.3%. Only 1 patient required revision surgery. No severe complications such as spinal cord, neural, or large vascular injury occurred during the operation. CONCLUSIONS Posterior-only surgical correction of dystrophic scoliosis in patients with NF1 using a MAPM could yield satisfactory clinical efficacy of correction and fusion.

Object The authors recently used a combined approach of minimally invasive transpsoas extreme lateral interbody fusion (XLIF) and open posterior segmental pedicle screw instrumentation with transforaminal lumbar interbody fusion (TLIF) for the correction of coronal deformity. The complications and radiographic outcomes were compared with a posterior-only approach for scoliosis correction. Methods The authors retrospectively reviewed all deformity cases that were surgically corrected at the University of Pittsburgh Medical Center Presbyterian Hospital between June 2007 and August 2009. Eight patients underwent combined transpsoas and posterior approaches for adult degenerative thoracolumbar scoliosis. The comparison group consisted of 4 adult patients who underwent a posterior-only scoliosis correction. Data on intra- and postoperative complications were collected. The pre- and postoperative posterior-anterior and lateral scoliosis series radiographic films were reviewed, and comparisons were made for coronal deformity, apical vertebral translation (AVT), and lumbar lordosis. Clinical outcomes were evaluated by comparing pre- and postoperative visual analog scale scores. Results The median preoperative coronal Cobb angle in the combined approach was 38.5° (range 18–80°). Following surgery, the median Cobb angle was 10° (p < 0.0001). The mean preoperative AVT was 3.6 cm, improving to 1.8 cm postoperatively (p = 0.031). The mean preoperative lumbar lordosis in this group was 47.3°, and the mean postoperative lordosis was 40.4°. Compared with posterior-only deformity corrections, the mean values for curve correction were higher for the combined approach than for the posterior-only approach. Conversely, the mean AVT correction was higher in the posterior-only group. One patient in the posterior-only group required revision of the instrumentation. One patient who underwent the transpsoas XLIF approach suffered an intraoperative bowel injury necessitating laparotomy and segmental bowel resection; this patient later underwent an uneventful posterior-only correction of her scoliotic deformity. Two patients (25%) in the XLIF group sustained motor radiculopathies, and 6 of 8 patients (75%) experienced postoperative thigh paresthesias or dysesthesias. Motor radiculopathy resolved in 1 patient, but persisted 3 months postsurgery in the other. Sensory symptoms persisted in 5 of 6 patients at the most recent follow-up evaluation. The mean clinical follow-up time was 10.5 months for the XLIF group and 11.5 months for the posterior-only group. The mean visual analog scale score decreased from 8.8 to 3.5 in the XLIF group, and it decreased from 9.5 to 4 in the posterior-only group. Conclusions Radiographic outcomes such as the Cobb angle and AVT were significantly improved in patients who underwent a combined transpsoas and posterior approach. Lumbar lordosis was maintained in all patients undergoing the combined approach. The combination of XLIF and TLIF/posterior segmental instrumentation techniques may lead to less blood loss and to radiographic outcomes that are comparable to traditional posterior-only approaches. However, the surgical technique carries significant risks that require further evaluation and proper informed consent.

Abstract Background: The rate of scoliosis in syringomyelia patients ranges from 25 to 74.4%. In turn, syringomyelia occurs in 1.2% to 9.7% of scoliosis patients. Aim: To evaluate outcomes of surgical correction of the scoliotic deformity in syringomyelia patients. Materials and methods: Between 1996 and 2015, 3120 patients with scoliosis of various etiologies were treated at the Clinic for Child and Adolescent Vertebrology of the Novosibirsk Research Institute of Traumatology and Orthopedics. We conducted a retrospective analysis of syringomyelia-associated scoliosis cases that required surgical correction. Results: Syringomyelia was found in 33 patients (1.05%) out of 3120 patients with spinal deformities of various etiologies; in 21 patients (0.9%) with idiopathic scoliosis of 2334 patients. In identifying the neurological deficit, the recommended first step is to perform neurosurgery. Nineteen patients were operated using the CDI, 4 patients underwent correction VEPTR, in 1 case instrumentation could not be established, 9 patients are undergoing treatment in the department of neurosurgery at the moment. Worsening of neurological deficits was not observed in any patient. Conclusion: A comparison of the results of syringomyelia-associated scoliosis correction with the data of other authors was done. The choice of surgery tactics is strictly individual and depends on the size of the cavity. The result of surgical intervention is generally positive and the loss of correction by the end of follow-up is negligible.

CONTEXT: Colonic carcinoids, excluding those arising in the appendix, have proved to be extremely rare. Due to their rarity, the characteristics and behavior of this unusual malignancy remain unclear. OBJECTIVE: To review the clinicopathologic features of patients operated on carcinoid tumors of the colon. METHODS: Twenty-three patients (12 males and 11 females) were operated on colonic carcinoids. The mean age of the patients was 63.0 ± 12.9 years (42 to 85 years). The clinical and histopathological data of patients who were pathologically diagnosed as having carcinoid tumors and submitted to surgical treatment over a 30-year period (1977-2007) were gathered. Actuarial patient survival was estimated using the Kaplan-Meier method, with carcinoid-specific death as the outcome. RESULTS: The mean time elapsed between onset of symptoms and surgical treatment was 8.3 months (1.5 to 20 months). The most frequent symptoms or signs encountered were abdominal pain followed by anorexia or weight loss, diarrhea, abdominal tenderness, palpable abdominal mass, and rectal bleeding. No carcinoid syndrome was noted. The lesion was located in the cecum in 16 (69.6%) patients, in the sigmoid in 3 patients (13.0%), in the ascending colon in 3 patients (13.0%), and in the transverse colon in one patient (4.3%). Twenty-one (91.3%) patients were operated on curative intent. Spreading of the disease to the liver and peritoneum was found in two (8.7%) patients who submitted to intestinal bypass. The mean size of the largest mass was 3.7 ± 1.2 cm (1.5 to 6.2 cm). There were multiple (two or more) lesions in three cases (13.0%). In the resected cases, the lymph nodes were compromised in 10 patients (47.6%) and disease-free in 11 (52.4%). Venous invasion and neural infiltration were both present in five (23.8%) patients. The tumors had penetrated the muscularis propria in all resected cases. Four (17.4%) patients had a second non-carcinoid primary tumor. Three (13.0%) patients died due to postoperative complications and five (21.7%) patients died from metachronous metastases or local recurrence. Fifteen patients (65.2%) remain alive without evidence of active disease. The mean follow-up period was 12 years (1.2 to 18 years), whereas the mean global survival was 50.7 ± 34.2 months and the crude survival rate at 5 years was 62.7%. CONCLUSIONS: Carcinoid tumors of the colon are frequently right-sided and may be clinically occult until an advanced stage is reached. Based on the relatively poor survival rates reported, it is recommended that, in addition to standard surgical resection, vigorous surveillance for metastatic disease must be performed, particularly during the first 2 years after surgery. In addition, these patients require evaluation of the entire gastrointestinal tract for evidence of coexisting malignancy, along with an extended period of follow-up, because tumor recurrences after 5 years are not uncommon.

Background: Bronchiectasis is usually caused by pulmonary infections and bronchial obstructions. It is still a serious problem in developing countries, as our country. We reviewed the morbidity and mortal-ity rates and outcomes of bronchiectasis surgical treatment. Patients and methods: Between years 2000 and 2016, one hundred and seven (107) patients, sixty nine (69) of whom female and thirty eight (38) male underwent pulmonary resection for bronchiecta-sis. The mean age was 35years (range, 13–66 years). Mean duration of symptoms was 12 years. Results: Symptoms were copious amount of purulent sputum in 84 patients, expectoration of foul-smelling sputum in 72, haemoptysis in 21 and cough in all patients. The indications for pulmonary resection were: medical therapy failure in eighty two (82) patients, massive haemoptysis in eighteen and lung abscess in seven (7) patients. The disease was bilateral in twenty seven (27) patients and mainly confined in the lower lobe. Eighty six (86) patients had a lobectomy, 7 had a segmentectomy, two patients right pneumonectomy. Operative morbidity was seen in 47 patients (43.9 %) and mor-tality in two (2) patients. Follow-up was complete in 97 patients with a mean of 5 years. Overall, 78 patients were asymptomatic after surgical treatment; symptoms were improved in 24, and unchanged or worse in 5. Conclusions: Surgical treatment of bronchiectasis is more effective in patient with localized disease. It is satisfactory with acceptable ratio of morbidity and mortality.

Abstract In recent years, with the in-depth research on spinal tuberculosis, posterior surgery alone has been praised highly by more and more surgeons due to the better correction of kyphosis, better maintenance of spinal physiological curvature, smaller surgical trauma and fewer surgical complications. However, there is currently lack of relevant reports about the efficacy of posterior surgery alone in the treatment of tuberculosis in the T4-6 segments. This study aimed to evaluate the clinical study efficacy and feasibility of one-stage posterior-only surgical treatment for thoracic spinal tuberculosis in the T4-6 segments. 67 patients with tuberculosis in T4-6 segments who underwent one-stage posterior-only surgery were included in this study. The clinical efficacy was evaluated using statistical analysis based on the data about erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Oswestry Dability Index (ODI) score, Visual Analogue Scale (VAS) score and Cobb angle before surgery, after surgery and at the last follow-up. All patients completed fusion during the follow-up period of 6–9 months. ESR and CRP were returned to normal for all patients at 6 months follow-up. In the meanwhile, among the 27 patients combined with neurological impairment, neurological functions of 22 cases (81.48%) recovered completely at the last follow-up (P < 0.05). Cobb angle of the kyphosis was improved from preoperative 34.8 ± 10.9° to postoperative 9.6 ± 2.8°, maintaining at 11.3 ± 3.2° at the last follow-up, The ODI and VAS scores were improved by 77.10% and 81.70%, respectively. This 5-year follow-up study shows that better clinical efficacy can be achieved for tuberculosis in T4-6 segments using one-stage posterior-only approach by costotransverse debridement in combination with bone graft and internal fixation. The posterior surgical method cannot only effectively accomplish debridement, obtain satisfactory clinical results, but also well correct kyphotic deformity and maintain it.

Abstract PurposeThe present study aimed to explore the influence of ulnar bow on the surgical treatment of Bado type I missed Monteggia fracture in children.MethodsThis study is a retrospective review of 24 patients between November 2010 and March 2019. All patients were treated with open reduction of the radial head and ulnar opening wedge osteotomy without annular ligament reconstruction. The mean interval between injury onset and surgery was five months (range: 2–12 months). The average age of participants at the time of surgery was 6.4 years (range: 3–10 years). We evaluated the maximum ulnar bow (MUB) and MUB position (P-MUB) via radiography. The patients were divided into middle group (group A: 14 cases, MUB located at 40% to 60% of the distal ulna) and distal group (group B: 10 cases, MUB located at 20% to 40% from the distal end of the ulna) based on P-MUB. The mean period of follow-up was 37 months (range: 6–102 months).ResultsAt the last follow-up, all the children showed stable reduction of the radial head, and the flexion function of elbow joint improved after operation (P<0.05). Group A presented a larger the ratio of maximum ulnar bow(R-MUB) and angle of ulnar osteotomy(OA) than group B (P<0.05). There was statistically significant difference between group A and Group B in the P-MUB (P < 0.05). The osteotomy angle was positively correlated with the R-MUB (R2 =0.497,P=0.013), The osteotomy angle was positively correlated with the P-MUB (R2=0.731,P=0.000), The R-MUB is proportional to the P-MUB (R2 =0.597,P=0.002). The regression equation of P-MUB and osteotomy angle: Angle=7.064+33.227* P-MUB (R2=0.459, P =0.000).ConclusionWhen the ulnar bow is positioned at the middle ulna, a stable reduction of radial head need to be achieved through a larger angle in the ulnar osteotomy. If the position of maximum ulnar bow (P-MUB) is closer to the middle of the ulna or the ratio of maximum ulnar bow (R-MUB) is larger, the osteotomy angle is larger.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Abstract Background Many types of bone grafting have been reported for successful use in achieving anterior column support and bone fusion after one stage posterior debridement in the treatment of lumbar spinal tuberculosis. However, none-structural bone grafting has rarely been studied. This study was aimed to identify the feasibility of none-structural bone grafting from comparing the advantages and disadvantages with structural bone grafting in the treatment of lumbar spinal tuberculosis. Patients and methods We retrospectively reviewed patients with lumbar spinal tuberculosis who had undergone none-structural (n=27) and structural (n=22) bone grafting after single-stage posterior debridement and instrumentation with at least 24 months of follow-up. Plain radiographs, magnetic resonance imaging, and computed tomography scans, as well as health-related outcomes, including Visual Analog Scale for back pain, the Oswestry Disability Index were collated before surgery and at follow-up. Results Both none-structural and structural bone grafting were associated with significant improvements in quality of life parameters, the laboratory tests and the Cobb angle of local kyphosis. A slight loss of Cobb angle correction was in both two groups, without any associated complications. The operation duration and blood loss in none-structural bone grafting group was significantly less. The bone fusion rate was higher in structural bone grafting group. There were three complications in the none-structural bone grafting and four complications in the structural bone grafting group; the incidence of complications between the two groups was not significantly different. Conclusions Based on single-stage posterior debridement and pedicle screws fixation, none-structural bone grafting can achieve anterior column support with reducing surgical trauma, simplifying surgical procedure and decreasing intraoperative hemorrhage, but the lower rate of grafted bone fusion should be taken into consideration when choosing the aforementioned method.

Aims To report the mid-term results of a modified self-growing rod (SGR) technique for the treatment of idiopathic and neuromuscular early-onset scoliosis (EOS). Methods We carried out a retrospective analysis of 16 consecutive patients with EOS treated with an SGR construct at a single hospital between September 2008 and December 2014. General demographics and deformity variables (i.e. major Cobb angle, T1 to T12 length, T1 to S1 length, pelvic obliquity, shoulder obliquity, and C7 plumb line) were recorded preoperatively, and postoperatively at yearly follow-up. Complications and revision procedures were also recorded. Only patients with a minimum follow-up of five years after surgery were included. Results A total of 16 patients were included. Six patients had an idiopathic EOS while ten patients had a neuromuscular or syndromic EOS (seven spinal muscular atrophy (SMA) and three with cerebral palsy or a syndrome). Their mean ages at surgery were 7.1 years (SD 2.2) and 13.3 years (SD 2.6) respectively at final follow-up. The mean preoperative Cobb angle of the major curve was 66.1° (SD 8.5°) and had improved to 25.5° (SD 9.9°) at final follow-up. The T1 to S1 length increased from 289.7 mm (SD 24.9) before surgery to 330.6 mm (SD 30.4) immediately after surgery. The mean T1 to S1 and T1 to T12 growth after surgery were 64.1 mm (SD 19.9) and 47.4 mm (SD 18.8), respectively, thus accounting for a mean T1 to S1 and T1 to T12 spinal growth after surgery of 10.5 mm/year (SD 3.7) and 7.8 mm/year (SD 3.3), respectively. A total of six patients (five idiopathic EOS, one cerebral palsy EOS) had broken rods during their growth spurt but were uneventfully revised with a fusion procedure. No other complications were noted. Conclusion Our data show that SGR is a safe and effective technique for the treatment of EOS in nonambulatory hypotonic patients with a neuromuscular condition. Significant spinal growth can be expected after surgery and is comparable to other published techniques for EOS. While satisfactory correction of the deformity can be achieved and maintained with this technique, a high rate of rod breakage was seen in patients with an idiopathic or cerebral palsy EOS.
