Abstract Background This study investigated the clinical efficacy and safety of a combination of debridement and extreme lateral internal fusion (XLIF) for mono-segmental spinal tuberculosis (TB). Methods The medical records of 9 patients (aged 21–70 years; 6 males) with mono-segmental spinal TB treated at our hospital between January 2014 and November 2016 were retrospectively reviewed. The involved vertebral bodies included 2 cases each at the T6/7, L2/3 or L3/4 level and 1 case each at the T7/8, T8/9, or T9/10 level. Results All patients were successfully treated with a combination of debridement and XLIF. The mean length of the operation was 97.3 ± 20.6 min (range, 65–126 min), and the mean blood loss during surgery was 151.1 ± 25.7 ml (range, 105–185 ml). Two patients experienced sensory disturbance over the left thigh and iliopsoas muscle weakness after surgery. After a mean follow-up of 12.3 ± 3.7 months (range, 6–17 months), the mean Cobb angle decreased from 28.7 ± 6.7 degrees to 12.1 ± 3.7 degrees. The mean VAS pain score decreased from 7.2 ± 1.1 preoperatively to 2.3 ± 0.9 postoperatively. The mean bone graft fusion time was 5.6 months (range, 4.7–7.2 months). At the final follow-up, spinal cord injuries were evaluated as ASIA Grade D in 5 patients and ASIA Grade E in 4 patients. Conclusions A combination of debridement and XLIF is effective for the treatment of mono-segmental spinal TB, and is associated with minimal intraoperative trauma, few complications, and an improved quality of life for patients. Trial registration: This was a retrospective study. The study was approved by the institutional review board and the committee of our hospital. Informed consent to use their data was obtained from all patients before surgery.

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 To explore the therapeutic effect of early surgical intervention for active thoracic spinal tuberculosis (TB) patients with paraparesis and paraplegia. Methods Data on 118 active thoracic spinal TB patients with paraparesis and paraplegia who had undergone surgery at an early stage (within three weeks of paraparesis and paraplegia) from January 2008 to December 2014 were retrospectively analyzed. The operation duration, blood loss, perioperative complication rate, VAS score, ASIA grade and NASCIS score of neurological status rating, Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), kyphotic Cobb’s angle, and duration of bone graft fusion were analyzed to evaluate the therapeutic effects of surgery. Results The mean operating time was 194.2 minutes, and the mean blood loss was 871.2 ml. The perioperative complication rate was 5.9 %. The mean preoperative VAS score was 5.3, which significantly decreased to 3.2 after the operation and continued decreasing to 1.1 at follow up (P<0.05). All cases achieved an increase of at least one ASIA grade after operation. The rate of full neurological recovery for paraplegia (ASIA grade A and B) was 18.0 % and was significantly lower than the rate (100 %) for paraparesis (ASIA grade C and D) (P<0.05). On the NASCIS scale, the difference in the neurological improvement rate between paraplegia (22.2 % ± 14.1 % in sensation and 52.2 % ± 25.8 % in movement) and paraparesis (26.7 % ± 7.5 % in sensation and 59.4 % ± 7.3 % in movement) was remarkable (P<0.05). Mean preoperative ESR and CRP were 73.1 mm /h and 82.4 mg/L, respectively, which showed a significant increase after operation (P>0.05), then gradually decreased to 11.5 ± 1.8 mm/h and 2.6 ± 0.82 mg/L, respectively, at final follow up (P<0.05). The mean preoperative kyphotic Cobb’s angle was 21.9º, which significantly decreased to 6.5º after operation (P<0.05) while kyphotic correction was not lost during follow up (P>0.05). The mean duration of bone graft fusion was 8.6 ± 1.3 months. Conclusions Early surgical intervention may be beneficial for active thoracic spinal TB patients with paraparesis and paraplegia, with surgical intervention being more beneficial for recovery from paraparesis than paraplegia.

Abstract Introduction Laparoscopic fundoplication (LF) has almost completely replaced the open procedure performed for gastroesophageal reflux disease (GERD) and hiatus hernia (HH). Several studies have suggested that long-term results with surgery for GERD are better than a medical line of management. In this retrospective study, we outline our experience with LF over 10 years. Also, we analyze the factors that would help us in better patient selection, thereby positively affecting the outcomes of surgery. Patients and Methods In this retrospective study, we identified 27 patients (14 females and 13 males) operated upon by a single surgeon from 2010 to 2020 at our institution. Out of these, 25 patients (12 females and 13 males) had GERD with type I HH and 2 (both females) had type II HH without GERD. The age range was 24 to 75 years. All patients had undergone oesophago-gastro-duodenoscopy (OGD scopy). A total of 25 patients had various degrees of esophagitis. Two patients had no esophagitis. These patients were analyzed for age, sex, symptoms, preoperative evaluation, exact procedure performed (Nissen’s vs. Toupet’s vs. cruroplasty + gastropexy), morbidity/mortality, and functional outcomes. They were also reviewed to examine the length of stay, length of procedure, complications, and recurrent symptoms on follow-up. Symptoms were assessed objectively with a score for six classical GERD symptoms preoperatively and on follow-up at 1-, 4- and 6-weeks postsurgery. Further evaluation was performed after 6 months and then annually for 2 years. Results 14 females (53%) and 13 males (48%) with a diagnosis of GERD (with type I HH) and type II HH were operated upon. The mean age was 46 years (24–75 years) and the mean body mass index (BMI) was 27 (18–32). The range of duration of the preoperative symptoms was 6 months to 2 years. The average operating time dropped from 130 minutes for the first 12 cases to 90 minutes for the last 15 cases. The mean hospital stay was 3 days (range: 2–4 days). In the immediate postoperative period, 72% (n = 18) of the patients reported improvement in the GERD symptoms, while 2 (8%) patients described heartburn (grade I, mild, daily) and 1 (4%) patient described bloating (grade I, daily). A total of 5 patients (20%) reported mild dysphagia to solids in the first 2 postoperative weeks. These symptoms settled down after 2 to 5 weeks of postoperative proton-pump inhibitor (PPI) therapy and by adjusting consistency of oral feeds. There was no conversion to open, and we observed no perioperative mortality. There were no patients who underwent redo surgeries in the series. Conclusion LF is a safe and highly effective procedure for a patient with symptoms of GERD, and it gives long-term relief from the symptoms. Stringent selection criteria are necessary to optimize the results of surgery. Experience is associated with a significant reduction of operating time.

PurposeTo find a radiographic method that best correlates with the mean subaxial cervical space available for the cord (MSCSAC) by using a fixed size parameter as radiographic reference, in contrast to the use of vertebral bodies as reference in the mean subaxial cervical Torg ratio (MTorg).MethodsThe study was approved by an institutional review board and written informed consent was obtained. Radiographs and cervical neck MRI were obtained from 18 male rugby athletes (age 18–30 years). Rheumatic disease, symptomatic cervical orthopaedic disease and previous cervical injury were used as exclusion criteria. MSCSAC and MTorg were calculated for each individual as the space available for the cord and Torg ratio averages from C3 to C6, respectively. A new radiographic method, using a metal bar as a size parameter (the corrected diameter of the cervical canal - CDCC), was also calculated for each individual, as well as its average from C3 to C6 (mean corrected diameter of the cervical canal - MCDCC). Values obtained for MCDCC and MTorg were correlated with those obtained by the MSCSAC using Pearson’s coefficient.ResultsFour volunteers were excluded due to previous cervical injury. In total, 14 subjects had their radiographs and MRIs analysed. Pearson’s correlation between MSCSAC and MTorg was 0.5706 (p=0.033). The correlation between MSCSAC and MCDCC was 0.6903 (p=0.006).ConclusionMCDCC correlates better than MTorg with MSCSAC and may be a better radiographic option than MTorg for cervical stenosis evaluation.

Abstract AimTo investigate the effect of orthokeratology (OK) lens on axial length (AL) elongation in myopia with anisometropia children.MethodsThirty-seven unilateral myopia (group 1) and fifty-nine bilateral myopia with anisometropia children were involved in this 1-year retrospective study. And bilateral myopia with anisometropia children were divided into group 2A (diopter of the lower SER eye under − 2.00D) and group 2B(diopter of the lower SER eye is equal or greater than − 2.00D). The change in AL were observed.The datas were analysed using SPSS 21.0.Results(1) In group 1, the mean baseline AL of the H eyes and L eye were 24.70 ± 0.89 mm and 23.55 ± 0.69 mm, respectively. In group 2A, the mean baseline AL of the H eyes and L eyes were 24.61 ± 0.84 mm and 24.00 ± 0.70 mm respectively. In group 2B, the mean baseline AL of the H eyes and L eyes were 25.28 ± 0.72 mm and 24.70 ± 0.74 mm. After 1 year, the change in AL of the L eyes was faster than the H eyes in group 1 and group 2A (all P<0.001).While the AL of the H eyes and L eyes had the same increased rate in group 2B. (2) The effect of controlling AL elongation of H eyes is consistent in three groups (P = 0.559).The effect of controlling AL elongation of L eyes in group 2B was better than that in group 1 and group 2A (P < 0.001). And the difference between group 1 and group 2A has no statistical significance. (3) The AL difference in H eyes and L eyes decreased from baseline 1.16 ± 0.55mm to 0.88 ± 0.68mm after 1 year in group 1.And in group 2A, the AL difference in H eyes and L eyes decreased from baseline 0.61 ± 0.34mm to 0.48 ± 0.28mm. There was statistically significant difference (all P<0.001). In group 2B, the baseline AL difference in H eyes and L eyes has no significant difference from that after 1 year (P = 0.069).ConclusionsMonocular OK lens is effective on suppression AL growth of the myopic eyes and reduce anisometropia value in unilateral myopic children. Binocular OK lenses only reduce anisometropia with the diopter of the low eye under − 2.00D. Binocular OK lenses cannot reduce anisometropia with the diopter of the low eye equal or greater than − 2.00D. Whether OK lens can reduce refractive anisometropia value is related to the spherical equivalent refractive of low refractive eye in bilateral myopia with anisometropia children after 1-year follow-up.

Background: Extreme Lateral Interbody Fusion (XLIF®) is a well-known transpsoas approach technique that confers advantages including excellent visualization, easy access to the lumbar disc, accommodation for a large anterior graft, restoration of disk height and lumbar alignment, and indirect decompression. However, no study in Thailand has investigated early postoperative complications after spinal fusion with XLIF surgery. Objective: To determine the early postoperative complication rates among Thai patients that underwent spinal fusion with XLIF procedure. Materials and Methods: The present study was a retrospective chart review to evaluate perioperative and early postoperative complications in patients that underwent spinal interbody fusion with XLIF procedure and were followed-up for a minimum of three months at the Department of Orthopedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand between 2015 and 2019. Results: One hundred eighteen patients, including 82 females and 36 males, with a mean age of 64.2 years and 165 levels, that were operated upon, were included. Eighty patients (67.8%) underwent one-level fusion, 29 (24.6%) had two-level fusion, and 9 (7.6%) underwent three-level fusion. Immediate postoperative complications occurred in 66 patients (55.9%), consisting of eight (6.7%) with medical complications, 57 (48.3%) with surgical complications, and one (0.8%) with combined medical and surgical complications. Postoperative complications were resolved within three months after surgery in 48 patients. Forty-one patients (34.7%) had postoperative proximal lower limb neuropathy. Only 10 patients (24.4%) still had neuropathy at the 3-month follow-up, but it did not affect their function. Conclusion: Postoperative proximal limb neuropathy, including thigh numbness, pain, or hip flexor weakness, had a high prevalence in the present study despite intraoperative neurophysiologic monitoring; however, most cases resolved by the 3-month follow-up. Patient education about potential nerve irritation complication is recommended, and meticulous preoperative radiographic assessment and careful step-by-step intraoperative surgical approach may reduce the rates of these postoperative complications.

Purpose To evaluate in a retrospective study the long-term usefulness of red 647 nm krypton and 670 nm diode laser for transscleral contact cyclophotocoagulation (CPC) in the treatment of therapy-resistant inflammatory glaucoma. Methods The authors treated 48 eyes of 38 consecutive patients (mean age 36.8 years, range 6–81 years) with therapy-resistant inflammatory glaucoma secondary to chronic uveitis (45/48), chronic scleritis (1/48), or combined scleritis with keratouveitis (2/48) using transscleral red 647 nm Krypton or 670 nm Diode laser. All eyes had failed maximum tolerated medical therapy and 19/48 (40%) eyes also previous antiglaucoma surgery. Laser power at the scleral surface was 0.35 to 0.45 W and the application time 10 seconds each. The follow-up was 42.8± 40.0 (range 2–145) months. Results The mean preoperative intraocular pressure (IOP) of 35.6±8.1 mmHg fell to 6–21 mmHg level in 75% after one or repeated CPC. Among adult patients this was achieved in 85%, among children in 54%. More than one treatment was needed in 52%. No cases of hypotony, phthisis bulbi, or other devastating complications occurred. Conclusions Transscleral CPC using red 647 nm krypton or 670 nm diode laser is an effective and well-tolerated procedure for the treatment of therapy-resistant inflammatory glaucoma in adults. CPC can be considered before incisional antiglaucoma surgery with a shunt or antimetabolites is undertaken

The sliding genioplasty for cosmetic augmentation of microgenia is a common procedure performed by maxillofacial and cosmetic surgeons. There are multiple designs for this osteotomy, and multiple fixation techniques proposed, among which include wires, screws, bone plates, and pins. Likewise, there are many advantages and disadvantages to each of the designs and the fixation techniques that will be utilized according to the surgical indications and the surgeon's preference. A techique used at the Medical College of Wisconsin in Milwaukee involves fixation of the osteotomy segments with Kirschner pins placed at multiple divergent angles. This technique allows for placement of the free segments in virtually any location, and provides for a type of rigid stabilization, particularly in large anterior and vertical movements. One criticism that has been suggested with the use of Kirschner pins is the possibility of migration. This retrospective study evaluates 13 patients who underwent augmentation genioplasty, rigidly fixated with Kirschner pins. Twenty-eight total Kirschner pins were placed, with one being removed. The mean postoperative follow-up was 32 months, and the average number of pins placed was 2.15 per patient. It would appear then, from this study, that migration of Kirschner pins when used with the sliding genioplasty, is not a significant postoperative concern.

Abstract Background The management of thoracolumbar burst fractures traditionally involves posterior pedicle screw fixation, but it has some drawbacks. The aim of this study is to evaluate the clinical and radiological outcomes of patients with thoracolumbar burst fractures. They were treated by a modified technique that monoaxial pedicle screws instrumentation and distraction-compression technology assisted end plate reduction. Methods From March 2014 to February 2016, a retrospective study including 42 consecutive patients with thoracolumbar burst fractures was performed. The patients had undergone posterior reduction and instrumentation with monoaxial pedicle screws. The fractured vertebrae were also inserted screws as a push point. The distraction -compression technology was used as assisting end plate reduction. All patients were followed up at a minimum of 2 years. These parameters including segmental kyphosis, severity of fracture, neurological function, canal compromise and back pain were evaluated in preoperatively, postoperatively and at the final follow-up. Results The average follow-up period was 28.9 ± 4.3 months (range, 24-39mo). No patients had postoperative implant failure at recent follow-up. The mean Cobb angle of the kyphosis was improved from 14.2°to 1.1° (correction rate 92.1%). At final follow-up there was 1.5% loss of correction. The mean preoperative wedge angle was improved from 17.1 ± 7.9°to 4.4 ± 3.7°(correction rate 74.3%). The mean anterior and posterior vertebral height also showed significant improvements postoperatively, which were maintained at the final follow-up(P < 0.05). The mean visual analogue scale (VAS) scores was 8 and 1.6 in preoperation and at the last follow-up, and there was significant difference (p < 0.05). Conclusion Based on our experience, distraction-compression technology can assist reduction of collapsed endplate directly. Satisfactory fracture reduction and correction of segmental kyphosis can be achieved and maintained with the use of monoaxial pedicle screw fixation including the fractured vertebra. It may be a good treatment approach for thoracolumbar burst fractures.
