Abstract
Video-assisted thoracic surgery (VATS) has been growing in popularity over the past 2 decades as an alternative to open thoracotomy for the treatment of several spinal conditions, and in the field of minimally invasive surgery, it now acts as a keyhole to the thoracic spine. MATERIALS AND METHODS Most VATS approaches are from the right side for pathologies involving the middle and upper thoracic spine because there is a greater working spinal surface area lateral to the azygos vein than that lateral to the aorta. Below T-9, a left-sided approach is made possible because the aorta moves away from the left posterolateral aspect of the spine to an anterior position as it passes through the diaphragm. RESULTS VATS has been used extensively in spinal deformities such as scoliosis. The use of VATS in spine surgery includes the treatment of thoracic prolapsed disk diseases, vertebral osteomyelitis, fracture management, vertebral interbody fusion, tissue biopsy, anterior spinal release, and fusion without or with instrumentation (VAT-I) for spinal deformity correction. As the knowledge and the comfort of using such techniques have expanded, the indications have extended to corpectomy for tumor resections. DISCUSSION AND CONCLUSIONS In the field of minimally invasive surgery, VATS now acts as a keyhole to the thoracic spine and an alternative to open thoracotomy for the treatment of several spinal conditions.Although VATS can be performed in such spine conditions, it is most beneficial in the treatment of scoliotic deformity, which requires taking a multilevel approach, from the upper to the lower thoracic spine.

Long-term experience with simultaneous prone video-assisted thoracoscopic anterior spinal release and posterior spinal fusion in severe rigid pediatric spinal deformities. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:724-732. [PMID: 33417038 DOI: 10.1007/s00586-020-06711-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 11/27/2020] [Accepted: 12/23/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE While posterior-alone techniques have been successful for most pediatric spinal deformities, anterior spinal release may be useful for severe rigid deformities. Traditional lateral-positioned video-assisted thoracoscopic surgical release (VATSR) followed by prone posterior spinal fusion (PSF) has been criticized for adding extensive operative morbidity. We aimed to reduce its disadvantages by performing prone VATSR and PSF simultaneously and evaluate its long-term outcomes. METHODS All consecutive patients from 1991 to 2012 undergoing VATSR and PSF at one institution were retrospectively reviewed. The inclusion criteria comprised severe rigid thoracic scoliosis (> 70°, bending correction > 45°) or kyphosis (> 75°, bolster correction > 45°), and a minimum 2 year follow-up. Demographics, operative data, hospital stay, and radiographic correction data were compared between patients who had undergone sequential VATSR followed by PSF and those who had undergone these procedures simultaneously. RESULTS Of 153 patients who had undergone VATSR and PSF, 53 met the inclusion criteria (31 sequential, 22 simultaneous; average follow-up, 50 [range, 24-86] months). Age, preoperative measurements and flexibility, and perioperative complications did not differ significantly. The simultaneous group showed significantly lower operative time (449 vs. 618 min), blood loss (1039 vs. 1906 cc), and hospital stay (6.3 vs. 8.5 days) (all, p < 0.05). Postoperative radiographic correction and maintenance at the final follow-up showed a non-significant trend favoring the simultaneous group. CONCLUSION Our simultaneous prone VATSR and PSF technique showed significantly lower operative time, blood loss, and hospital stay compared with the traditional sequential VATSR and PSF method, suggesting its value in treating rigid deformities.

Puthezhath K. Expressing Cobb Angle as Linear Measurement in Scoliosis and Its Significance: A Clinical and Geometrical Analysis of Scoliosis. KOREAN JOURNAL OF SPINE 2018; 14:139-142. [PMID: 29301173 PMCID: PMC5769934 DOI: 10.14245/kjs.2017.14.4.139] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Revised: 12/22/2017] [Accepted: 12/26/2017] [Indexed: 11/24/2022]
Abstract
Objective The aim of this study was to formulate an objective clinical and geometric relationship between Cobb angle and the difference between the lengths of convex and concave sides (convexo-concave vertebral difference) of the structural curve in scoliosis. Is it possible to express Cobb angle in such a way that it could be visualized as a length, especially while planning for surgical correction of scoliosis? Methods Thirty consecutive patients below the age of 19 years with a scoliosis of Cobb angle more than 10 degrees were included in the study. Convexo-concave vertebral difference of the structural curve was measured. Its relationship with the measure of Cobb angle was studied. Results Author obtained a significant linear correlation between the convexo-concave vertebral differences and the Cobb angle. Using the formula Y=2d.Sin (X/2) the convexo-concave vertebral difference could be predicted. The difference thus obtained gives a quantitative measure of the maximum length of correction possible in the structural curve. Conclusion It is possible to express the Cobb angle as a function of linear measurement. The author proposes that this would aid the surgeons to accurately and predictably achieve the desired scoliosis correction.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To analyze the patient satisfaction and the patients' perceived approach-related morbidity (ArM) after open thoracotomy (OTC) for instrumented anterior scoliosis surgery. SUMMARY OF BACKGROUND DATA There is no mid- to long-term data on the patients' perceived ArM concerning chest wall dissection for open anterior scoliosis correction. METHODS A specific questionnaire was used to retrospectively evaluate mid- to long-term follow-up data concerning ArM after OTC of patients younger than 30 years (range, 11-28 years) who underwent anterior open transthoracic scoliosis surgery. The questionnaire was comprised of detailed scar-related questions. Applying strict inclusion criteria, we could analyze outcomes in terms of percentage morbidity (morbidity [%]) of 40 patients who underwent OTC for instrumented scoliosis correction. RESULTS Mean age of the patients was 16 ± 3.8 years, follow-up was 61.5 ± 72.6 months on average, and mean incision length was 25.7 ± 3.1 cm. Mean number of levels fused was 5.9 ± 1.5. Single thoracotomy was performed in 25 patients and a thoracoabdominal approach in 15 patients. Mean morbidity (0%, not delineating no ArM; 100%, delineating highest ArM) was 5.4% ± 11.3%; 47.5% of patients had no morbidity; 12.5% had morbidity >10% (mean: 28.5%). Signs of intercostal neuralgia (ICN) were present in 10%. Patients judged their clinical outcome as "good" in 20% and "excellent" in 80%. Statistical analysis did not reveal differences in outcomes and percentage morbidity concerning age of patients, extent of approach (thoracotomy vs. thoracoabdominal approach) and incision length, gender, or follow-up length. However, the presence of ICN had a significant effect on the outcome, showing high correlation with increased morbidity (P < 0.0001). In the clinical judgment of outcomes, the severity of the ArM after OTC was mild, except for 2 patients who had moderate approach and scar-related morbidity. CONCLUSION ArM after open thoracic spinal surgery or thoracoscopic procedures can be assessed using the questionnaire. The current study showed that ArM in young patients who underwent OTC for anterior instrumented scoliosis correction was low. Patients with increased signs of ICN did worse in terms of the questionnaire survey. The study showed that neither cosmesis nor scar-related problems were a concern for patients undergoing OTC.

Abstract
STUDY DESIGN Cadaver dissection and measurement. OBJECTIVE To describe a previously undocumented intracostal ligament that limits the potential space through which the T1 ventral ramus passes before joining the C8 ventral ramus. SUMMARY OF BACKGROUND DATA Preclavicular entrapment of the T1 ventral ramus can lead to radiculopathy, neurogenic thoracic outlet syndrome, or both, the so called "double crush" phenomenon. The usual sites of entrapment include the neural foramen, the interscalene interval, an aberrant cervical rib, the first rib itself, or an apical thoracic mass. METHODS A total of 42 shoulders from 21 embalmed cadavers (13 male, 8 female) were dissected. The presence of the ligament was noted and its anatomic characteristics were measured with digital calipers by 3 independent investigators. Means, ranges, and standard deviations were calculated. RESULTS The average ligament length was 31.0 mm (SD, 4.3). The ligament was trapezoidal in shape, and wider anteriorly. The mean anterior width was 7.1 mm (SD, 3.8), midsubstance width 3.6 mm (SD, 1.5), and posterior width 3.5 mm (SD, 1.3). The mean thickness was 0.5 mm (SD, 0.3), and the maximal opening through which the T1 nerve passed between the first rib and the ligament was 6.3 mm (SD, 1.6). The ligament was present on at least one side in 81% of individuals (67% of shoulders): 52% bilateral and 29% unilateral. CONCLUSION This previously undescribed ligament is a robust structure, present on at least one side in over 80% of the individuals studied. When present, the ligament creates a narrow interval between the ligament and the first rib that the T1 ventral ramus traverses before crossing the first rib superiorly and contributing to the inferior trunk of the brachial plexus. Although the actual clinical significance has not been demonstrated, this ligament may represent another entrapment site for the T1 ventral ramus.

Abstract
BACKGROUND: Anterior access to the thoracic spine is done by open thoracotomy (OTC) or video-assisted thoracoscopic surgery (VATS). VATS is known as the method which results in lower morbidity rates, but there is little evidence of its less invasiveness. Objective: The current study yielded for outcome data concerning patients' perception of approach-related morbidity (ArM) following OTC for spinal surgery and that of a control group having a chest tube thoracotomy (CTT). METHODS: We performed a questionnaire assessment of ArM after OTC and CTT. Applying strict inclusion criteria, we compared outcomes in terms of percentage morbidity (Morbidity %) of 43 patients that underwent OTC for instrumented scoliosis correction to 30 patients that had CTT for minor thoracic pathologies (e.g., pneumothorax). RESULTS: Mean age in CTT and OTC Group was 50.2 and 16.5 years old, follow-up was of 32.2 and 58.4 months, and mean incision length was 2.5 and 25.5 cm, respectively. Mean number of levels fused in the OTC Group was 5.8. Mean morbidity (0% delineating no cases, 100% delineating highest morbidity) for the CTT Group was 10.8±15.4% (0-59.5%), 42% of patients had no morbidity. Signs of intercostal neuralgia (ICN) were present in 16.7%. A total of 35.5% had a morbidity >10% (mean: 27.5%), and 10% of morbidity cases were defined as having a chronic post-thoracotomy pain (CPP). In the OTC Group, mean morbidity was 7.0±12.7% (0-52.1%), 44% had no morbidity. Out of the sample, 18.6% had morbidity >10% (mean: 28.6%). Signs of ICN were present in 14%. In both groups, the presence of ICN had a significant impact on and showed correlation with morbidity (p<0.0001). In terms of clinical judgement, the severity of the ArM after a CTT or OTC was generally mild except for one patient in each group. Age and follow-up were significantly different between groups (p<0.0001, p=0.02), but the intergroup difference in morbidity was not significant (p=0.08). CONCLUSIONS: ArM after open thoracic spinal surgery or VATS procedures can be assessed using the questionnaire. To put ArM of OTC into perspective, a Control Group with simple CTT was selected, demonstrating that morbidity was not different between the OTC and CTT groups. Patients with increased signs of ICN do worse which was reflected by increased morbidity in both groups. The study demonstrates that not only the cosmesis is not a concern for patients undergoing OTC, but neither is the ArM a concern, equalling that of a simple CTT.

Abstract
ABSTRACT
OBJECTIVE
To review the concepts involved in the decision-making process for management of pediatric patients with spinal deformity.
METHODS
The literature was reviewed in reference to pediatric deformity evaluation and management.
RESULTS
Pediatric spinal deformity includes a broad range of disorders with differing causes, natural histories, and treatments. Appropriate categorization of pediatric deformities is an important first step in the clinical decision-making process. An understanding of both nonoperative and operative treatment modalities and their indications is requisite to providing treatment for pediatric patients with spinal deformity. The primary nonoperative treatment modalities include bracing and casting, and the primary operative treatments include nonfusion instrumentation and fusion with or without instrumentation. In this article, we provide a review of pediatric spinal deformity classification and an overview of general treatment principles.
CONCLUSION
The decision-making process in pediatric deformity begins with appropriate diagnosis and classification of the deformity. Treatment decisions, both nonoperative and operative, are often predicated on the basis of the age of the patient and the natural history of the disorder.

Abstract
Thoracic spine fusion may be indicated in the surgical treatment of a wide range of pathologies, including trauma, deformity, tumor, and infection. Conventional open procedures for surgical treatment of thoracic spine disease can be associated with significant approach-related morbidity, which has motivated the development of minimally invasive approaches. Thoracoscopy and, later, video-assisted thoracoscopic surgery were developed to address diseases of the thoracic cavity and subsequently adapted for thoracic spine surgery. Although video-assisted thoracoscopic surgery has been used to treat a variety of thoracic spine diseases, its relatively steep learning curve and high rate of pulmonary complications have limited its widespread use. These limitations have motivated the development of minimally invasive posterior approaches to address thoracic spine pathology without the added risk of morbidity involved in surgically entering the chest. Many of these advances are ongoing and represent the forefront of minimally invasive spine surgery. As these techniques are developed and applied, it will be important to assess their equivalence or superiority in comparison with standard open techniques using prospective trials. In this paper the authors focus on minimally invasive posterior thoracic procedures that include fusion, and provide a review of the current literature, a discussion of future pathways for development, and case examples. The topic is divided by pathology into sections including trauma, deformity, spinal column tumors, and osteomyelitis.

Abstract
Adolescent idiopathic scoliosis (AIS) affects 1-3% of children in the at-risk population of those aged 10-16 years. The aetiopathogensis of this disorder remains unknown, with misinformation about its natural history. Non-surgical treatments are aimed to reduce the number of operations by preventing curve progression. Although bracing and physiotherapy are common treatments in much of the world, their effectiveness has never been rigorously assessed. Technological advances have much improved the ability of surgeons to safely correct the deformity while maintaining sagittal and coronal balance. However, we do not have long-term results of these changing surgical treatments. Much has yet to be learned about the general health, quality of life, and self-image of both treated and untreated patients with AIS.

Abstract
STUDY DESIGN A retrospective assessment of fusion rates using either morselized allograft bone or demineralized bone matrix (DBM) following video-assisted thoracoscopic surgery (VATS) in idiopathic scoliosis. OBJECTIVE To compare fusion rates between allograft bone and demineralized bone matrix (Grafton DBM Flex) following VATS using on standard standing lateral spine radiographs. SUMMARY OF BACKGROUND DATA Both VATS and bone graft substitutes are accepted surgical techniques. However, their concomitant use in spinal deformity surgery has not been previously reported. Bone graft substitute has the advantage of decreasing operative time, blood loss, and donor site morbidity associated with autografts. METHODS Anterior thoracic discectomies were performed using VATS. Forty patients with 1 year or more follow-up were evaluated-12 with morselized allograft bone (Allograft group) and 28 with folded Grafton DBM Flex (DBM group). Factors analyzed included age, number of anterior levels fused, operative time, anterior perioperative blood loss, curve correction, and fusion rates. Clinical and radiographic evaluations were performed before surgery and at month, 1 year, and at most recent follow-up. Interbody fusion was assessed on standing lateral radiographs using the Newton et al 4-level grading scale. RESULTS There were no significant differences in age at surgery, number of anterior vertebral levels fused, anterior operative time per level, anterior intraoperative blood loss, chest tube drainage and duration, or total perioperative anterior blood loss between the 2 groups. Percent curve correction from before surgery to the most recent follow-up were very similar in both Allograft (68%) and DBM groups (67%). At most recent assessment, 60 of 73 disc spaces (82%) in the Allograft group and 100 of 109 disc spaces (92%) in the DBM group were rated as radiographically fused (Newton et al Grade I and II). There was no significant difference between the 2 groups (P = 0.088). No patients were observed to have crankshaft, pseudoarthrosis or hardware failure. There were no complications related to the bone graft material used. CONCLUSION Demineralized bone matrix (Grafton DBM Flex) seem to be an effective bone graft substitute in thoracoscopic surgery for idiopathic scoliosis.

Abstract
Neurofibromatosis type 1 (NF-1) is a multisystemic disease. It may manifest as abnormalities of the nervous tissue, bones, soft tissue, and skin. The manifestations of NF-1 vary from person to person and range from subclinical to severe. Individuals who carry the gene eventually exhibit some clinical feature of the disease. The penetrance for NF-1 nears 100% during adulthood. Skeletal abnormalities are common in NF-1, with most patients presenting with some type of bony dysplasia. The orthopedic complications usually appear early. They include spinal deformities, such as scoliosis or kyphosis, congenital tibial dysplasia with bowing and pseudarthrosis of the tibia, forearm, other bones, as well as overgrowth phenomenon of an extremity, and soft tissue tumors.

Abstract
OBJECTIVE The aim of this study was to analyze the impact of the learning curve on the preliminary results of video-assisted thoracic surgery for spinal deformities in a general hospital setting. PATIENTS AND METHODS We retrospectively reviewed the medical records of 15 patients who underwent video-assisted thoracic surgery performed by a multidisciplinary team comprising orthopedic and thoracic surgeons. Endoscopic anterior release and fusion were followed by posterior instrumentation in a single procedure. Demographic, orthopedic, morbidity, and mortality statistics were compiled for the 15 patients and compared to results reported for similar series. RESULTS Endoscopic surgery was indicated for 15 patients: 11 women (73.3%) and 4 men (26.7%). The median age was 15 years (interquartile range [IQR], 14-19 years). Three patients (20%) required conversion to thoracotomy. There were 2 serious (13.3%) and 3 minor complications (20%). They all resolved satisfactorily and there was no perioperative mortality. The median Cobb angle was 71 degrees (IQR, 63.75 degrees -75.25 degrees ) before surgery and 41 degrees (IQR, 30 degrees -50 degrees ) after surgery. Median duration of surgery was 360 minutes (IQR, 300-360 minutes), duration of postoperative recovery unit stay was 1.5 days (IQR, 1-2.75 days), and total hospital stay was 11.5 days (IQR, 8.25-14 days). CONCLUSIONS Despite the complexity of video-assisted thoracic surgical procedures, we believe they will become the standard approach to treating spinal deformities in the near future. By working together in general hospital settings, orthopedic and thoracic surgeons can help to overcome the steep yet manageable learning curve.

Abstract
STUDY DESIGN Retrospective review of patients with idiopathic scoliosis who underwent same-day or staged anterior and posterior spinal fusion and segmental spinal instrumentation. OBJECTIVE Evaluation of our learning curve with video-assisted thoracoscopic surgery (VATS) with respect to operative time, blood loss, and complications in patients with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA VATS is a minimally invasive alternative to thoracotomy in the management of idiopathic scoliosis. An increased or steep learning curve has been described in the initial application of this technique. METHODS We began performing VATS in 1998. We compared our first 25 consecutive VATS patients (Group 2) and subsequent 28 consecutive VATS patients (Group 3) to our previous 16 consecutive patients (Group 1) with a thoracotomy (1991-1998) for idiopathic scoliosis. Training at a sponsored regional course was obtained before performing our first VATS procedure. RESULTS VATS allowed more disc to be excised in Group 2 (4.5 +/- 1, 5.7 +/- 1, and 4.4 +/- 1 discs in Group 1, Group 2, and Group 3, respectively) and significantly decreased the anterior operative time (215 +/- 33, 260 +/- 56, and 177 +/- 47 minutes) and time per individual disc excision (50 +/- 13, 47 +/- 12, and 41 +/- 12 minutes), while providing comparable correction of the thoracic deformity (67% +/- 12%, 66% +/- 10%, and 70% +/- 13% correction). There was no increase in estimated intraoperative anterior blood loss (228 +/- 213, 183 +/- 136, and 211 +/- 158 mL), estimated blood loss per disc excised (51 +/- 42, 34 +/- 29 and 48 +/- 37 mL), or complications in the VATS groups. Complications were primarily pulmonary and resolved with medical therapy. Postoperative chest tube drainage (855 +/- 397, 462 +/- 249, and 561 +/- 261 mL) and total perioperative anterior blood loss (1083 +/- 507, 647 +/- 309, and 773 +/- 308 mL) were significantly decreased in the VATS groups, but this was attributed to the use of Amicar. CONCLUSIONS VATS is an effective procedure for anterior spinal fusion in idiopathic scoliosis. The learning curve is short, provided appropriate training is obtained.

Abstract
A retrospective study of 21 patients with idiopathic scoliosis who underwent endoscopic thoracoplasty was done. The objective of the study was to report and assess the morbidity and mid term outcomes of video-assisted thoracoplasty in idiopathic scoliosis. Patients with idiopathic scoliosis often present cosmetic complaints due to their rib deformity. This deformity may still exist after surgical correction of the main scoliotic curve. Endoscopic thoracoplasty has been reported as a safe method in limited cases of idiopathic scoliosis. Between 2002 and 2004, 21 patients underwent endoscopic anterior release and thoracoplasty for significant rib hump deformity associated with idiopathic scoliosis. Patients were operated on lateral position, with two endoscopic ports. Anterior release and rib resection were performed during the first stage, and instrumented posterior fusion was performed in a second stage. Patients were evaluated preoperatively, 1 week after surgery, 6 months after surgery and at their most recent follow-up with clinical and radiological measurement of the rib deformity. The mean age at surgery was 14.9 years old (range 13-17 years). The average Cobb's angle of the main scoliotic curve was 70 degrees (range 60 degrees -85 degrees). Average follow-up was 25 months (range 23-32 months). The mean number of resected ribs was five ribs (range 4-7) and the mean length of the resected rib was 4.2 cm (range 2.2-7 cm). Average operating time of endoscopic thoracoplasty (including anterior release) was 65 min (range 45-108 min). The mean preoperative height of rib hump deformity was 3.6 cm (range 2.5-5.5 cm). It was reduced to 1.5 cm at most recent follow-up. There was no significant thoracic pain necessitating medication postoperatively. No complications related to endoscopic anterior release and rib hump resection occurred in the series. Endoscopic thoracoplasty is a safe and reliable technique in idiopathic scoliosis. If indicated, the anterior release can be performed with video-assistance and the thoracoplasty can be performed on the same stage.

Abstract
The understanding of idiopathic scoliosis continues to evolve. At some time in the foreseeable future the term will be oxymoronic. It may eventuate, based on a series of laboratory and genetic tests, that there will be three groups: One in which the curve will never be of significance and regular follow-up is unnecessary. A second group with predictable response to a brace. A third group in which spine fusion is an inevitability. This latter group should be allowed to enjoy childhood and early adolescence unfettered by treatment until such time as surgery is necessary. Until then, efforts must be directed toward early detection, comprehensive evaluation, and best efforts at preventing progression of the curve. To this end, a referral to an orthopedic surgeon for suspected scoliosis never is disparaged.

Abstract
Neuroendoscopy has grown rapidly in the last 20 years as a therapeutic modality for treating a variety of spinal disorders. Spinal endoscopy has been widely used to treat patients with cervical, thoracic, and lumbosacral disorders safely and effectively. Although it is most commonly used with minimally invasive lumbar spine surgery, endoscopy has gained widespread acceptance for the treatment of thoracic disc herniations and for anterior release and rod implantation in the correction of thoracic spinal deformity. The authors review the use of endoscopy in spine surgery and in the treatment of spinal disorders as well as in the treatment of intrathoracic nonspinal lesions. Endoscopy has some significant advantages over open or other minimally invasive techniques in that it can allow for better visualization of the lesion, smaller incision sizes with reduced morbidity and mortality, reduced hospital stays, and ultimately lower cost. In addition, spinal endoscopy allows observers and operating room staff to be more involved in each case and fosters education. Spinal endoscopy, like any novel modality, carries with it additional risks and the surgeon must always be prepared to convert to an open procedure. The learning curve for spinal endoscopy is steep and the procedure should not be attempted alone by a novice surgeon. Nevertheless, with training and experience, the spine surgeon can achieve better outcomes, reduced morbidity, and better cosmesis with spinal endoscopy, and the operating times are comparable to open procedures. As technology evolves and more experience is obtained, neuroendoscopy will likely achieve further roles as a mainstay in spine surgery.
