Abstract INTRODUCTION 3D printing technology is penetrating the healthcare field at an astonishing rate. The reduction of its costs, makes it more accessible to everyone. MATERIAL AND METHODS 35-year-old woman who had functional limitation in her right hip due to pelvic ring fracture in her childhood. She had dysmetria of lower limbs and femoral anteversion of 40 degrees. Imaging tests showed vicious consolidation of the right hemipelvis associated with antero-medial displacement. RESULTS Preoperative, we performed her 3D printing pelvic ring model. Osteotomies were digital planned (iliac crest, superior pubic ramus, incomplete of inferior pubic ramus, and semicircular of posterior column) and also how many degrees we would need for rotation the osteotomized fragment. Posterior column osteotomy was the most difficult, so we designed 3D surgical printing cutting guide able to being inserted into the iliac fossa. We used it to introduced four Kirschnner wires that leads us as a guide to avoid the greater sciatic notch. O-arm navigation system helped us make sure to achieve more precision. 3D printing pelvic ring model was sterilized to pre-contouring osteosynthesis plates. After two years of follow-up, good functional results were observed, without gait claudication either limb dysmetria. Her range of motion is 105 degrees of hip flexion, 20 degrees of internal hip rotation and 40 degrees of external hip rotation. Complete radiological consolidation was observed. CONCLUSION Digital planning and 3D printing technology allows to improve three-dimensional compression of bone pathology leading to a higher likelihood of a predictable ideal outcome compared to conventional techniques.

Background and objective: The objective of this study is to clarify clinical, immunological, and neuroimaging features in anti-aquaporin-4 (AQP4) antibody-positive and antibody-negative Sjögren’s syndrome (SS) patients with central nervous system (CNS) involvement. Methods: Medical records and MRI scans were retrospectively analyzed in 22 consecutive SS patients with CNS manifestations. Results: Seven (31.8%) patients were positive for anti-AQP4 antibodies. The frequency of visual impairment was higher in anti-AQP4 antibody-positive patients than in antibody-negative patients (71.4% vs. 0.0%, p = 0.0008). Brain MRI showed that discrete lesions were more commonly found in the cerebrum, brainstem, and optic nerve in anti-AQP4 antibody-positive patients than in antibody-negative patients ( p = 0.002, p = 0.006, and p = 0.004, respectively), while spinal cord MRI showed that posterior column lesions in the cervical spinal cord were more frequent in anti-AQP4 antibody-positive patients than in antibody-negative patients (71.4% vs. 14.3%, p = 0.01). SS-A antibody titers were higher in anti-AQP4 antibody-positive patients than in antibody-negative patients ( p = 0.012) and were also higher in patients with longitudinally extensive spinal cord lesions (LESCLs) than in those without LESCLs ( p = 0.019). Conclusions: In SS, the presence of anti-AQP4 antibodies is associated with involvement of the optic nerve, cerebrum and brainstem, and with cervical posterior column lesions in the spinal cord.

Background Some malignant pelvic tumor may affect the anterior or posterior column at the acetabula area. The postoperative recurrenceand complication rate are high. Precise resection with safe surgical margin could cure the patients while saving healthier host bone for relative simple reconstruction.Questions/Purposes The purpose of this study is to evaluate the effect of precise single column resection and reconstruction with femoral head plus THR for malignant pelvic tumorswith respect to the (1) surgical safety, (2) oncological outcome and (3) prosthesis survivorship and function.Methods This is a clinical cases study. From 2007 to 2015, 19 patients with primary malignant tumors of the pelvis were enrolled in the study. The diagnosis included 16 cases of chondrosarcoma, 1 case of undifferentiated polymorphic sarcoma, 1 case of Ewing's sarcoma and 1 case of solitary plasmacytoma. All tumors were resected with safe surgical margins, which were proved by the postoperative specimen evaluation. Anterior column was involved in 17 cases and posterior column in 2 cases. Ten of 19 tumors were resected assisted by computer navigation. Femoral heads were used to reconstruct anterior or posterior column defects and fixed by screws; THR was used for the joint reconstruction. Oncologic outcome and function were evaluated by regular follow-up.Results The follow up time was more than 12 months in 14 cases with the average of 58.4 months (median 61, range 13-118) months. Surgical margins contained wide resection in 12 cases and marginal resection in 7 cases. The bony wide resection rate was 90% (9/10) in the navigation group and 77.8% (7/9) in free hand group respectively. One patient with Ewing's sarcoma died 14 months postoperative due to lung metastasis. There was only one case with chondrosarcoma was found recurrence in 61 months postoperatively, who was in the navigation group and having marginal margin resection. There was one prosthesis removed due to prosthesis infection (14 months postoperatively). There were another two patients with minor wound infection. The average MSTS function score was 24.8 (17-29).Conclusions The current treatment method is oncological safe and functional with less complications. The hardware is relatively cost effective and right on the shelf. However, this procedure is highly skill needed.
