Abstract Background Both hybrid therapy (HT) and total en bloc spondylectomy (TES)can lead to good results for solitary radioresistant metastatic spinal tumors with high-grade epidural spinal cord compression (ESCC). However, there is still a lack of comparative studies on the treatment efficacy of these two methods. Methods We retrospectively reviewed patients with the above-mentioned tumors between January 2012 and May 2019. A total of 157 patients underwent surgery, among whom 64 received HT, and 93 were treated with TES. Propensity score matching allowed the generation of best-matched pairs for the 2 categories (1:1 ratio). Local control rates and survival rates were estimated using the Kaplan–Meier method. Results All patients received a minimum of 2-year follow-up. The longest follow-up time was 88 months. The survival rates and local progression-free survival rates after HT were comparable with TES at 1 year (84.6% vs. 83.1%; 90.2% vs. 90%), 2 year (60.8% vs. 64.3%; 64.1% vs. 62.1%), and 5 year (18.8% vs. 24.1%; 24.4% vs. 28.4%). There were no significant differences in pain control, improvement of neurological status, spine stabilization restoration, and improvement in quality of life between groups. However, HT showed more advantages in shortening operative time and reducing intraoperative blood loss than TES. Conclusion Our results suggest that HT can obtain satisfactory results comparable to TES for solitary radioresistant metastatic spinal tumors with high-grade ESCC. In addition, compared with TES, HT has the advantages of shortening operative time and reducing perioperative complications. For solitary radioresistant metastatic spinal tumors with a high degree of ESCC, HT may be a promising treatment in the future.

Objective: To investigate the neurological recovery of Frankel A spinal giant cell tumor (GCT) patients after they had received a Total En Bloc Spondylectomy (TES). Materials and Methods: We retrospectively recorded data of three patients (two females) with mobile spine GCT (T6, T10, and L2) Enneking stage III with complete paralysis before surgery, who had undergone TES in our institute from January 2018 to September 2020. The duration of neurologic recovery to Frankel E was the primary outcome. The intra-operative blood loss, operative time, operative-related complications, and the local recurrence were the secondary outcomes. Results: The duration of suffering from Frankel A to TES surgery was 2 months for the T6 patient, 3 weeks for the T10 patient, and 1 month for the L2 patient. Three patients had achieved full neurological recovery to Frankel E within 6 months after TES (T6 for 5 months, T10 for 3 months, and L2 for 3 months). The average blood loss was 2833.33 ml and the mean operative time was 400 min. Up until the last follow-up (13–25 months), no evidence of local recurrences had been found in any of the three patients. Conclusion: Frankel A spinal GCT patients can achieve full neurological recovery after TES, if the procedure is performed within 3 months after complete paraplegia. TES can effectively control any local recurrences.

Abstract Background Instrumentation failure (IF) is a common complication after total en bloc spondylectomy (TES) in spinal tumors. This study aims to evaluate the clinical outcomes of TES combined with the satellite rod technique for the treatment of primary and metastatic spinal tumors. Methods The clinical data of 15 consecutively treated patients with spinal tumors who underwent TES combined with the satellite rod technique by a single posterior approach from June 2015 to September 2018 were analyzed retrospectively. Radiographic parameters including the local kyphotic angle (LKA), anterior vertebral height (AVH), posterior vertebral height (PVH), and intervertebral titanium mesh cage height (ITMCH) were assessed preoperatively, postoperatively, and at the final follow-up. The visual analog scale (VAS), Oswestry Disability Index (ODI), and American Spinal Injury Association (ASIA) scale were used to assess quality of life and neurological function. The operative duration, volume of blood loss, and complications were also recorded. Results The mean operation time and volume of blood loss were 361.7 min and 2816.7 mL, respectively. During an average follow-up of 31.1 months, 2 patients died of tumor recurrence and multiple organ metastases, while recurrence was not found in any other patients. Solid fusion was achieved in all but one patient, and no implant-related complications occurred during the follow-up. The VAS, ODI, and ASIA scores significantly improved from before to after surgery (P < 0.05). The LKA, AVH, and PVH significantly improved from before to immediately after surgery and to the final follow-up (P < 0.05), and the postoperative and final follow-up values did not significantly differ (P > 0.05). Conclusions TES combined with the satellite rod technique can yield strong three-dimensional fixation and reduce the occurrence of rod breakage, thereby improving the long-term quality of life of patients with spinal tumors.

✓ The authors report the case of a 53-year-old woman with monostotic fibrous dysplasia of the thoracic spine. The patient presented with a 1-month history of pain in the thoracic spinal region. En bloc resection of the lesion was successfully performed via a transthoracic approach, and a histopathological examination confirmed the diagnosis of fibrous dysplasia. At 24-month follow-up examination, pain and vertebral instability were absent. The findings in this case illustrate that, although very rare, monostotic fibrous dysplasia of the thoracic spine should be considered in the differential diagnosis of spinal tumors. Although a consensus for management of this disease has not been achieved, the authors recommend radical removal of all involved bone as well as internal fixation or bone graft—assisted fusion to achieve long-term stabilization.

Background: Clinical outcomes after meniscal allograft transplantation (MAT) in arthritic knees are unclear, and objective estimates of graft survival according to the articular cartilage status have not been performed. Hypothesis: MAT should provide clinical benefits in knees with high-grade cartilage damage, but their graft survivorship should be inferior to that in knees with low-grade chondral degeneration after MAT. Study Design: Cohort study; Level of evidence, 3. Methods: The records of 222 consecutive patients who underwent primary MAT were reviewed to compare clinical outcomes and graft survivorship. The patients were grouped according to the degree and location of articular cartilage degeneration: low-grade chondral lesions (International Cartilage Repair Society [ICRS] grade ≤2) on both the femoral and tibial sides (ideal indication), high-grade lesions (ICRS grade 3 or 4) on either the femoral or tibial side (relative indication), and high-grade lesions on both sides (salvage indication). Kaplan-Meier survival analysis with the log-rank test was performed to compare the clinical survival rates and graft survival rates between the groups. A Lysholm score of <65 was considered a clinical failure, and graft failure was defined as a meniscal tear or meniscectomy of greater than one-third of the allograft, objectively evaluated by magnetic resonance imaging (MRI) and second-look arthroscopic surgery. Results: The mean (±SD) Lysholm score significantly improved from 63.1 ± 15.1 preoperatively to 85.1 ± 14.3 at the latest follow-up of a mean 44.6 ± 19.7 months ( P < .001). However, the postoperative scores were not significantly different between the 3 groups (85.7 ± 14.2 for ideal indication, 84.7 ± 17.0 for relative indication, and 84.7 ± 14.2 for salvage indication; P = .877). On MRI at the latest follow-up of a mean 23.0 ± 19.9 months and second-look arthroscopic surgery of a mean 19.3 ± 20.7 months, there were 25 (11.3%) failed MAT procedures (4 medial, 21 lateral); of these, 5 lateral MAT procedures (2.3%) went on to allograft removal. Clinical survival rates were not significantly different between the groups ( P = .256). However, on objective evaluation, the estimated cumulative graft survival rate at 5 years in the salvage indication group (62.2% [95% CI, 41.6-82.8]) was significantly lower than that in the other 2 groups (ideal indication: 93.8% [95% CI, 88.5-99.1]; relative indication: 90.9% [95% CI, 81.1-100.0]) ( P = .006). Conclusion: Our findings showed that MAT was an effective symptomatic treatment in knees with advanced bipolar chondral lesions. However, better graft survival can be expected when articular cartilage is intact or if chondral damage is limited to a unipolar lesion. MAT should be considered before the progression of chondral damage to a bipolar lesion for better graft survivorship and should be performed cautiously in arthritic knees.

Gastric Submucosal Tumors

Abstract Background Endoscopic resection, including endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFR), was used to resect small gastric submucosal tumors (SMTs). Our team explored a method of tumor traction using a snare combined with endoclips to assist in the resection of SMTs. This study aims to explore the safety and effectiveness of the method. Methods This research performed a propensity-score-matching (PSM) analysis to compare ESD/EFR assisted by a snare combined with endoclips (ESD/EFR with snare traction) with conventional ESD/EFR for the resection of gastric SMTs. Comparisons were made between the two groups, including operative time, en bloc resection rate, perioperative complications, and operation-related costs. Results A total of 253 patients with gastric SMTs resected between January 2012 and March 2019 were included in this study. PSM yielded 51 matched pairs. No significant differences were identified between the two groups in perioperative complications or the costs of disposable endoscopic surgical accessories. However, the ESD/EFR-with-snare-traction group had a shorter median operative time (39 vs 60 min, P = 0.005) and lower rate of en bloc resection (88.2% vs 100%, P = 0.027). Conclusions ESD/EFR with snare traction demonstrated a higher efficiency and en bloc resection rate for gastric SMTs, with no increases in perioperative complications and the costs of endoscopic surgical accessories. Therefore, the method seems an appropriate choice for the resection of gastric SMTs.
