Abstract Background To report on the technique and results of parallel endplate osteotomy (PEO) for severe rigid spinal deformity. Methods We retrospectively reviewed the clinical data of 36 patients with severe rigid spinal deformities who underwent PEO between July 2016 and December 2018 and who were followed up for at least 24 months. Results Following PEO, the kyphosis and scoliosis correction rates reached 77.4 ± 14.0% and 72.2 ± 18.2%, respectively. The median intraoperative estimated blood loss was 1500 mL and the median operative time was 6.8 h. The SF-36 scores of physical function, role-physical, bodily pain, general health, vitality, social function, role-emotional and mental health changed from 62 ± 28, 51 ± 26, 49 ± 29, 35 ± 30, 53 ± 28, 45 ± 30, 32 ± 34 and 54 ± 18 at baseline to 81 ± 16, 66 ± 41, 72 ± 40, 64 ± 44, 75 ± 25, 71 ± 46, 66 ± 34 and 76 ± 28 at 12 months postoperatively, 82 ± 32, 67 ± 42, 81 ± 30, 71 ± 41, 80 ± 30, 74 ± 36, 68 ± 35 and 85 ± 33 at 18 months postoperatively, and 86 ± 21, 83 ± 33, 88 ± 26, 79 ± 39, 86 ± 36, 86 ± 48, 80 ± 47 and 91 ± 39 at 24 months postoperatively, respectively. Conclusions PEO is an effective technique for successful correction of spinal deformities. At the two-year follow-up visit, all patients achieved better clinical results based on the SF-36 scores.

Background Clinical results and recurrence rate after microendoscopic diskectomy (MED) with long-term follow-up is still unclear, in spite of its relatively long history. Materials and Methods A total of 112 who underwent MED participated in this study. Operative time, blood loss, serum C-reactive protein (CRP), creatine kinase (CK), and visual analog scale (VAS) were evaluated as indexes of surgical invasiveness. The 36-Item Short Form Survey Instrument (SF-36), Japanese Orthopaedic Association (JOA) score, patient satisfaction, and recurrence were also evaluated with a follow-up of at least 5 years. Results The mean operative time was 86.7 minutes, and the mean blood loss was 35.7 mL. The mean CRP on postoperative day 3 and CK on the first postoperative day was 0.72 mg/dL and 224.6 IU/L, respectively, and VAS to assess surgical site pain on the first postoperative day was 24.9 mm on average. The improvement rate in the JOA score was 68.7%. The physical component summary of SF-36 in norm-based scoring was improved from 23.4 to 48.6. Overall, 90.8% of patients evaluated their response to the surgery as extremely satisfied or satisfied. The recurrence rate was 10.5%, and reoperation was performed in 7.9% of patients. Conclusions MED is a technique that offers both reduced invasiveness and good long-term clinical results.

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.

Category: Ankle, Arthroscopy, Hindfoot, Sports, Trauma Introduction/Purpose: Surgical management of osteochondral lesions of the talus (OLT) present an ongoing treatment challenge. Previously, matrix-induced autologous chondrocyte implantation (MACI) demonstrated improved pain and function at 7-years postoperative, providing evidence that MACI is a reliable method for treating cartilage. However, it is unknown the long- term results of MACI in OLT. The purpose of this study was to assess 13-year clinical follow-up data and the long-term success of this implant by comparing patient reported outcome measures (PROMs) pre-operatively, at 7-years post-operative, and at 13- years post-operative. Methods: A prospective investigation of MACI was performed on 10 patients with OLTs who had failed previous arthroscopic treatment. Of the 10 patients, 9 were available for 7-year and 13-year follow-up. Short Form Health Survey (SF-36) and the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot evaluation were utilized at pre-operative, 7-year, a 13-year postoperative. For each patient, a paired t-test was used to compare 13-year post-operative PROMs to pre-operative PROMs. A single factor analysis of variance (ANOVA) determined whether PROMs were different between pre-operative, 7-year post- operative, and 13-year post-operative time intervals. When a significant difference was detected, a post-hoc Tukey’s determined which time periods were different. Results: SF-36 data at 13-years showed significant improvements in Physical Functioning (p=0.012), Lack of Bodily Pain (p=0.017), and Social Functioning (p=0.007) compared with preoperative data. There were no differences in other components of the SF-36 outcomes (p>0.05). Although the AOFAS was on average 12 points higher at 13-years postoperative, this was not statistically significant (p=0.173). As for comparing PROMs over time, 13-years post-operative PROMs were comparable to 7-years post- operative (Table 1). There were better PROMs for Physical Functioning, Bodily Pain, and Social Functioning at 7- and 13-years post-operative compared to pre-operative while Physical Role Functioning was also better at 7-years post-operative compared to pre-operative. Conclusion: This study shows MACI provides greater pain relief and function at 13-years post-operative with stable long-term follow-up. MACI should be considered for osteochondral lesions that fail initial microfracture.

The purpose of the present paper is to describe our technique and experience with retroperitoneal hand-assisted laparoscopic (HAL) nephrectomies as an alternative to the transperitoneal approach. Eight retroperitoneal HAL nephrectomies and one partial nephrectomy were performed. Several excisional techniques were employed incorporating the Harmonic scalpel or Ligasure device. Hemostatic agents were used to cover the renal defect. Surgical bolsters were sutured to the renal capsule with pleget reinforcements to aid in hemostasis. The average operative time was 210 min and estimated blood loss 110 mL. Mean change in hematocrit was 3 units and creatinine was 1 point. No patient required a transfusion. There were no major complications, with a mean follow-up of fourteen months. On average, patients resumed oral intake in 2 days, and were discharged in 3 days. Pathological examination revealed that two lesions were benign and seven malignant. Tumor diameter averaged 3 cm. There were no positive surgical margins. In conclusion, we have demonstrated the feasibility of retroperitoneal laparoscopic hand-assisted nephrectomy and partial nephrectomy surgery for solid renal masses.

As bariatric surgery increases, there is a growing population of patients with biliary obstruction and anatomy which precludes transoral access through endoscopic retrograde cholangiopancreatography (ERCP). Minimally invasive transgastric ERCP (TG-ERCP) offers a feasible alternative for the treatment. A retrospective review was performed of all patients who underwent laparoscopic or robotic-assisted TG-ERCP between 2010 and 2017. Chart abstraction collected demographics, procedural details, success rate, and postoperative outcomes. Forty patients were identified, of which 38 cases were performed laparoscopically and two robotically. Median operative time was 163 minutes, with an estimated blood loss of 50 cc. TG-ERCP was performed successfully in 36 cases (90%); sphincterotomy was completed in 35 patients (97%). Sixty per cent already had a cholecystectomy; in the remaining patients, it was performed concurrently. Major complications included stomach perforation (n = 1), pancreatitis (n = 3), and anemia requiring transfusion (n = 2). In patients with biliary obstruction and anatomy not suitable for ERCP, TG-ERCP can be performed in a minimally invasive fashion, with a high rate of technical success and low morbidity. We describe a stepwise, reproducible technique because it is an essential tool for the shared armamentarium of endoscopists and surgeons.

We report a five year military experience with anterior retroperitoneal spine exposure combining vascular and neurosurgical spine teams. From August 2005 through April 2010 (56 months), hospital records from a single institution were retrospectively reviewed. Complications, estimated blood loss, transfusions, operative time and length of stay were documented. Eighty-four patients with lumbar spondylosis underwent primary (63, 75%) or secondary exposure (21, 25%) of a single- (66, 79%) or multilevel disc space (18, 21%). Median operative time and estimated blood loss were 127 minutes (range, 30–331 minutes) and 350 mL (range, 0–2940 mL). The overall complication rate was 23.8%. Postoperative complications included six blood transfusions (7%), three patients with retrograde ejaculation (3.57%) or surgical site infection; two with a prolonged ileus (2.38%) or ventral hernia and one each with a bowel obstruction (1, 1.19%), deep venous thrombosis or lymphocele. All-cause mortality was 1%. In conclusion, a team approach can minimize complications while offering the technical benefits and durability of an anterior approach to the lumbar spine.

This study describes the surgical technique and intra- and postoperative complications associated with the use of a radiofrequency bipolar coagulator in a series of 18 Piver type III-IV radical hysterectomies performed in cervical cancer patients. Preliminary vessel-by-vessel dissection of the lateral parametria was possible in 17 out of 18 (94%) cases, and a direct application of a radiofrequency bipolar coagulation instrument was performed to coagulate the posterior and anterior parametrial tissues in all cases. We were able to easily coagulate isolated vessels up to 5 mm of maximal diameter. In no case were clamps or hemoclips necessary to complete hemostasis. We did not observe any parametrial vessel damage or heat-related injury of the surrounding normal tissue. The median size of the parametria removed was 44 mm (range 31–58) and nodes were detected in 15 cases (83%). Median operative time and estimated blood loss for the whole procedure including systematic pelvic and aortic lymphadenectomy was 250 min (range 200–410) and 550 ml (range 400–2500), respectively. Median follow-up time was 9 months (range 5–13). No complications specifically related to the use of radiofrequency coagulation were found. In conclusion the radio-frequency coagulation with this instrument appears to be a safe technique that is particularly useful in reducing blood loss and operative time without affecting radicality in patients undergoing radical hysterectomy.

Objective Robotic-assisted minimally invasive esophagectomy (RAMIE) is an emerging complex operation with limited reports detailing morbidity, mortality, and requirements for attaining proficiency. Our objective was to develop a standardized RAMIE technique, evaluate procedure safety, and assess outcomes using a dedicated operative team and 2-surgeon approach. Methods We conducted a study of sequential patients undergoing RAMIE from January 25, 2011, to May 5, 2014. Intermedian demographics and perioperative data were compared between sequential halves of the experience using the Wilcoxon rank sum test and the Fischer exact test. Median operative time was tracked over successive 15-patient cohorts. Results One hundred of 313 esophageal resections performed at our institution underwent RAMIE during the study period. A dedicated team including 2 attending surgeons and uniform anesthesia and OR staff was established. There were no significant differences in age, sex, histology, stage, induction therapy, or risk class between the 2 halves of the study. Estimated blood loss, conversions, operative times, and overall complications significantly decreased. The median resected lymph nodes increased but was not statistically significant. Median operative time decreased to approximately 370 minutes between the 30th and the 45th cases. There were no emergent intraoperative complications, and the anastomotic leak rate was 6% (6/100). The 30-day mortality was 0% (0/100), and the 90-day mortality was 1% (1/100). Conclusions Excellent perioperative and short-term patient outcomes with minimal mortality can be achieved using a standardized RAMIE procedure and a dedicated team approach. The structured process described may serve as a model to maximize patients’ safety during development and assessment of complex novel procedures.

Purpose To compare patient characteristics, operative time, estimated blood loss (EBL), postoperative length of hospital stay (LOS) and complications after insertion and removal of submuscular plates (SMPs) versus flexible nails (FNs) for paediatric diaphyseal femur fractures. Methods We reviewed records of 58 children (mean age, 7.7 years SD 2.0) with diaphyseal femur fractures who underwent treatment with SMPs (n = 30) or FNs (n = 28) from 2005 to 2017 (mean follow-up, 22 months SD 28). Patients with pathological fractures or musculoskeletal comorbidities were excluded. Alpha = 0.05. Results Insertion of FNs was associated with shorter operative time (ß = –24 mins) and less EBL (ß = –38 mL) (both, p < 0.001) compared with insertion of SMPs, after adjusting for fracture type and time from beginning of study period. Removal of FNs was also associated with shorter operative time (ß = –15 min) compared with removal of SMPs (p < 0.001). EBL during removal was similar between groups (p = 0.080). The FN group had a shorter LOS after insertion (ß = –0.2 d) compared with the SMP group (p = 0.032). Four patients treated with SMPs and three treated with FNs developed surgical site infections. Two patients treated with SMPs and seven treated with FNs experienced implant irritation that resolved with removal. No other complications occurred. Conclusion Compared with SMPs, FNs were associated with shorter operative time (for insertion and removal), less EBL (for insertion) and shorter post-insertion LOS in patients with diaphyseal femur fractures. Level of Evidence: III
