Abstract Background Reconstruction of the skeletal defects resulting from the resection of bone tumors remains a considerable challenge and one of the possibilities is the orthotopic replantation of the irradiated bone autograft. One technical option with this technique is the addition of a vital autologous fibular graft, with or without microvascular anastomosis. The aim of our study was to evaluate the clinical results of the treatment of our patient cohort with a specific view to the role of fibular augmentation. Methods Twenty-one patients with 22 reconstructions were included. In all cases, the bone tumor was resected with wide margins and in 21 of them irradiated with 300 Gy. In the first case, thermal sterilization in an autoclave was used. The autograft was orthotopically replanted and stabilized with plates and screws. Fifteen patients underwent an additional fibular augmentation, 8 of which received microvascular anastomoses or, alternatively, a locally pedicled fibular interposition. Results the most common diagnosis was a Ewing sarcoma (8 cases) and the most common location was the femur (12 cases). The mean follow-up time was 70 months (16–154 months). For our statistical analysis, the one case with autoclave sterilization and 3 patients with tumors in small bones were excluded. During follow-up of 18 cases, 55.6% of patients underwent an average of 1.56 revision surgeries. Complete bony integration of the irradiated autografts was achieved in 88.9% of cases after 13.6 months on average. In those cases with successful reintegration, the autograft was shorter (n.s.). Microvascular anastomosis in vascularized fibular strut grafts did not significantly influence the rate of pseudarthrosis. Conclusions the replantation of extracorporeally irradiated bone autografts is an established method for the reconstruction of bone defects after tumor resection. Our rate of complications is comparable to those of other studies and with other methods of bone reconstruction (e.g. prosthesis). In our opinion, this method is especially well suited for younger patients with extraarticular bone tumors that allow for joint preservation. However, these patients should be ready to accept longer treatment periods.

Abstract Background: the reconstruction of the bone defects after the resection of bone tumors remains a considerable challenge and one of the possibilities is the orthotopic replantation of the irradiated bone autograft. One technical option with this technique is the addition of an autologous fibular graft, with or without microvascular anastomosis. The aim of our study was to evaluate the clinical results of the treatment of our patient cohort with a specific view to the role of fibular augmentation. Methods and patients: we were able to include 21 patients with 22 reconstructions. In all cases, the bone tumor was resected with wide margins and irradiated with 300 Gy. The autograft was orthotopically replanted and stabilized by means of osteosynthesis implants. 15 patients underwent an additional fibular augmentation, 8 of which received microvascular anastomoses or, alternatively, a local pedicled fibular interposition. Results: the most common diagnosis was a Ewing-sarcoma (8 cases) and the most common location was the femur (12 cases). The mean follow-up time was 70 months. During follow-up, 59% of patients underwent an average of 2.54 revision surgeries, with the most common reason being pseudarthrosis (6 cases). Complete bony integration of the irradiated autografts was achieved in 81.8% of cases after 13.6 months on average. In case of successful reintegration the autograft was shorter (n.s.). Fibular augmentation with or without microvascular anastomosis/pedicled blood supply did not correlate with the pseudarthrosis rate.Conclusions: the replantation of extracorporeally irradiated bone autografts is an established method for the reconstruction of bone defects after tumor resection. Our rate of complications is comparable to those of other studies and with other methods of bone reconstruction (e.g. prosthesis). In our opinion, this method is especially well suited for younger patients with extraarticular bone tumors maintainable joints.

The free vascularized fibular graft has been successfully applied as a reconstruction option in patient with large secondary skeletal defects result from excision of pathologic tissue after neurofibroma surgical excision. It provides a strong cortical strut for reconstruction of defects, so that the free vascularized fibular graft is ideal for ulna reconstruction. A 22-year-old male with lump in his right forearm for 3 months previously which become bigger and more painful. There was also sings of ulnar nerve disfunction. From the CPC result, we diagnosed forearm neurofibroma. We performed wide excision and reconstruction using free vascularized fibular graft. On the last follow up, the active and passive ranges of motion (ROM) of 4th and 5th metacarpal was measured with the help of a goniometer. The ulnar neurological state was tested by manual testing and graded on the Medical research council (MRC) scale. Four weeks after surgery, the operation wound at the right forearm and right lower leg was good and no infection signs. The graft viability was good with compromised vascularity. The post-operative passive and active ROM of the 4th and 5th metacarpal able did full extend. The post-operative sensoris level of the ulnar area improved from pre-operative sensoris level.Post-operative follow-up, in the early period (up to 6 weeks) we monitor the graft viability. Our case reported good result in the operation wound, the graft viability, the passive and active ROM of the 4th and 5th metacarpal and the sensoris level of the ulnar area.

AbstractWe report the first case of early postoperative infection after a medial hemiarthroplasty of the knee with a customized ConforMIS iForma™ interpositional device. The infection was treated successfully by revision surgery with implant removal and antibiotic therapy. Despite the additional diagnosis of rheumatoid arthritis that did not affect the treated knee, the preservation of bony and ligamentous structures enabled a successful re-implantation of another iForma™ implant 9 months later with good clinical results at follow-up examination 1 year postoperatively. This is very much in contrast to the extensive and complex revision surgery, with significant bone loss, in patients with infected unicompartmental or total knee arthroplasties. The iForma™ device may be an alternative treatment option in early and moderate unicompartmental arthritis of the knee, with easy revision with the same type of implant in the rare case of infection.

Abstract PURPOSE Unlike conventional operating rooms that provide a sterilized space, we have developed a Smart Cyber Operating Theater (SCOT) in which the room itself performs treatment as a single medical device. We report the clinical results of 3 types of SCOT. METHODS Basic SCOT packaged with intraoperative MRI (0.4Tesla) was introduced in Hiroshima University in 2016. Standard SCOT networked with middleware OPeLiNK was introduced to Shinshu University in 2018, and Hyper SCOT introduced to Tokyo Women’s Medical University in 2019. RESULTS The average of all 56 patients was 44 years old. There were 38 brain tumors (68%), 11 functional diseases (19%), and 7 orthopedic diseases (13%). Basic SCOT is used for 41 cases (/56; 73%) with 22 gliomas, 10 epilepsies, 7 bone tumors, and 2 benign brain tumors. Standard SCOT with 20 networked devices is used for 14 cases (/56; 25%) with 6 gliomas including brain stem and thalamus, 6 pituitary tumors and 2 benign brain tumors. The strategy desk can display a variety of digital data synchronized in time, and the review and comment functions also operate. It is useful for remote advice through mutual communication via strategy desk. Hyper SCOT was used in February 2019 for the first case (1/56 cases; 2%). MRI images were taken with an average of 1.3 shots with good image quality. For 46/56 neoplastic lesions (82%), additional removal of residual tumor was performed in 31/46 cases (67%), and 26/46 cases (57%) were totally removed, with an average removal rate of 89.2%. There was no reoperation (0%) within 1 month in all cases. CONCLUSIONS Three types of SCOT contributed to planned surgical outcome including maximal tumor resection without serious related complications. We will proceed with verification of clinical effects, and develop robotized devices, and utilize AI for strategy desk at Hyper SCOT.

Abstract Background Adequate margins are technically difficult to achieve for malignant tumors involving the sacroiliac joint due to limited accessibility and viewing window. In order to address the technical difficulties faced in iliosacral tumor resection, we proposed a technique for precise osteotomy, which involved the use of canulated screws and Gigli saw (CSGS) that facilitated directional control, anteroposterior linkage of resection points and adequate surgical margins. The purpose of the current study was to evaluate whether CSGS technique facilitated sagittal osteotomy at sacral side, and were adequate surgical margins achieved? Also functional and oncological outcomes was determined along with the noteworthy complications. Methods From April 2018 to November 2019, we retrospectively reviewed 15 patients who underwent resections for primary tumors of pelvis or sacrum necessitating iliosacral joint removal using the proposed CSGS technique. Chondrosarcoma was the most common diagnosis. The osteotomy site within sacrum was at ipsilateral ventral sacral foramina in 8 cases, midline of sacrum in 5 cases, and contralateral ventral sacral foramina and sacral ala with 1 case each. The average intraoperative blood loss was 3640 mL (range, 1200 and 6000 mL) with a mean operation duration of 7.4 hours (range, 5 to 12 hours). The mean follow-up was 23.0 months (range, 18 and 39 months) for alive patients. Results Surgical margins were wide in 12 patients (80%), wide-contaminated in 1 patient (6.7%), and marginal in 2 patients (13.3%). R0 resection was achieved in 12 (80%) patients and R1 resection in 3 patients. There were three local recurrences (20%) occurred at a mean time of 11 months postoperatively. No local recurrence was observed at sacral osteotomy. The overall one-year and three-year survival rate was 86.7% and 72.7% respectively.Complications occurred in three patients. Conclusions The current study demonstrated that CSGS technique for tumor resection within the sacrum and pelvis was feasible and can achieve ideal resection accuracies. The use of CSGS was associated with high likelihood of negative margin resections in the current series. Intraoperative use of CSGS appeared to be technically straightforward and allowed achievement of planned surgical margins. It is worthwhile to consider the use of CSGS technique in resection of pelvic tumors with sacral invasion and iliosacral tumors, however further follow-up at mid to long-term is warranted to observe local recurrence rate.

Abstract Background The first line of treatment for most cervical intradural tumors is surgical resection through laminotomy or laminectomy. This may cause a loss of posterior pulling force leading to kyphosis, which is associated with decreased functional outcome. However, the incidence and predictors of kyphosis in these patients are poorly understood. Object To assess the incidence of posterior fixation (PF), as well as predictors of radiological kyphosis, following resection of cervical intradural tumors in adults. Methods A population-based cohort study was conducted on adult patients who underwent intradural tumor resection via cervical laminectomy with or without laminoplasty between 2005 and 2017. Primary outcome was kyphosis requiring PF. Secondary outcome was radiological kyphotic increase, measured by the change in the C2–C7 Cobb angle between pre- and postoperative magnetic resonance images. Results Eighty-four patients were included. Twenty-four percent of the tumors were intramedullary, and the most common diagnosis was meningioma. The mean laminectomy range was 2.4 levels, and laminoplasty was performed in 40% of cases. No prophylactic PF was performed. During a mean follow-up of 4.4 years, two patients (2.4%) required delayed PF. The mean radiological kyphotic increase after surgery was 3.0°, which was significantly associated with laminectomy of C2 and C3. Of these, C3 laminectomy demonstrated independent risk association. Conclusions There was a low incidence of delayed PF following cervical intradural tumor resection, supporting the practice of not performing prophylactic PF. Kyphotic increase was associated with C2 and C3 laminectomy, which could help identify at-risk patients were targeted follow-up is indicated.

Elastofibroma (EF) is a benign proliferation of connective tissue and is typically located at the dorsal thoracic wall. Most patients complain about pain during motion in the shoulder girdle. The aim of our study was to evaluate the outcome after surgical treatment of EF. This study provides an overview of typical clinical findings, diagnostics and pathogenesis of this rare entity. In this retrospective study we analyzed data of 12 patients (6 male, 6 female) with EF treated in our institution between 2004 and 2012. The mean follow-up was 4.7 years (range: 5 months to 7.5 years). All tumors were found to be unilateral and all patients had a negative medical history for EF. Visual analogue scale and range of motion (ROM) was documented pre- and postoperatively. In all patients indication for surgical resection was pain or uneasiness during movement. There was no statistically significant difference in ROM of the shoulder between pre- and postoperatively but all patients reported significantly less pain after surgical resection. Patients benefited from tumor resection by a significant reduction of pain levels and improvement of the motion-dependent discomfort.

Background: Desmoplastic fibroma (DF) is an extremely rare locally aggressive bone tumor with an incidence of 0.11% of all primary bone tumors. The typical clinical presentation is pain and swelling above the affected area. The most common sites of involvement are the mandible and the metaphysis of long bones. Histologically and biologically, desmoplastic fibroma mimics extra-abdominal desmoid tumor of soft tissue. Case Presentation and Literature Review: A case of a 27-year old man with DF in the ilium, including the clinical, radiological and histological findings over a 4-year period is presented here. CT scans performed in 3-year intervals prior to surgical intervention were compared with respect to tumor extension and cortical breakthrough. The patient was treated with curettage and grafting based on anatomical considerations. Follow-up CT scans over 18-months are also documented here. Additionally, a review and analysis of 271 cases including the presented case with particular emphasis on imaging patterns in MRI and CT as well as treatment modalities and outcomes are presented. Conclusion: In patients with desmoplastic fibroma, CT is the preferred imaging technique for both the diagnosis of intraosseus tumor extension and assessment of cortical involvement, whereas MRI is favored for the assessment of extraosseus tumor growth and preoperative planning. While tumor resection remains the preferred treatment for DF, curettage and grafting prove to be an acceptable alternative treatment modality with close follow-up when resection is not possible. Curettage and grafting have been shown to provide good clinical results and are associated with long recurrence free intervals.

Abstract OBJECTIVE: Even during the microsurgical era, tentorial meningiomas present a formidable surgical challenge when tumor involves critical neurovascular structures. We report our experience with tentorial meningioma with regard to clinical presentation, diagnostic workup, microsurgical technique, complications, and follow-up results. METHODS: In a retrospective study, we reviewed the medical charts, neuroimaging data, and follow-up data of patients treated microsurgically for tentorial meningioma in our department between January 1989 and June 2002. Patients were routinely scheduled for clinical and radiological follow-up 6 months and 1 year after surgery. Thereafter, follow-up was performed every 1 or 2 years on the basis of the results of each follow-up examination. RESULTS: The main presenting symptoms of the patients (69 women and 12 men) were headache (75%), dizziness (49%), and gait disturbance (46%). The leading neurological signs were gait ataxia (52%) and cranial nerve deficits (28%). Extent of tumor resection was Simpson Grade I in 29 patients, Grade II in 45 patients, Grade III in 1 patient, Grade IV in 4 patients, and unknown in 2 patients. Permanent surgical morbidity and mortality were 19.8 and 2.5%, respectively. Clinical and magnetic resonance imaging follow-up was available in 74 patients for a period ranging from 1 to 13 years (mean, 5.9 yr). Of these, 64 patients (86%) have resumed normal life activity. Seven patients had tumor recurrence and four underwent reoperation. CONCLUSION: Careful preoperative planning of the surgical approach tailored to tumor location and extent is a prerequisite to achieve radical microsurgical tumor resection with minimal morbidity and mortality. Resection of an infiltrated but patent venous sinus is not recommended.
