Materials and methods Imaging findings in six patients with tumor-induced osteomalacia and histopathologically proven phosphaturic mesenchymal tumors were evaluated. Clinical and biochemical profiles of these patients were also assessed. Results Along with having a characteristic biochemical profile, patients with phosphaturic mesenchymal tumors also have certain imaging findings which can aid in the diagnosis such as increased uptake on DOTA PET-CT and homogeneous post-contrast enhancement on CT and MRI. Conclusion Patients with tumor-induced osteomalacia have characteristic symptoms, imaging and biochemical profiles. For radiologists, raising the suspicion of a phosphaturic mesenchymal tumor in patients with refractory hypophosphatemic osteomalacia as well as localizing the tumor on imaging is crucial, as complete excision of the tumor leads to resolution of the osteomalacia and the patient's clinical symptoms. © Indian Orthopaedics Association 2020.Background The family of patients undergo profound anxiety when their family member is undergoing major oncological surgery. In this study, we evaluated the effectiveness of periodic intraoperative text messages regarding the status of ongoing surgery in reducing anxiety levels among the patients' family members. Materials and Methods Family members of 60 patients (one for each patient) who were undergoing major oncological surgery lasting more than 1 h were recruited and randomized into two groups (30 patients each). Group 1 (no SMS group) did not receive any text message while Group 2 (SMS group) received periodic intraoperative text messages. Respondents aged less than 16 years, those with associated psychiatric illnesses, and those who did not consent to the study were excluded. Anxiety among family members was assessed using the Visual Analogue Scale for Anxiety (VAS-A) and Anxiety component of Hospital Anxiety and Depression Scale (HADS-A) at five different periods; (P1) 1 day prior to surgery (P2) at separation from family at the operation theatre (P3) 1 h after commencement of surgery (P4) immediately after completion of surgery, and (P5) 1 day after surgery. Results The mean VAS-A and HADS-S scores between both the groups did not show a statistically significant difference for P1, P2 and P5 assessment periods (preoperative period, separation in operation theatre, post-operative period). However, mean VAS-A and HADS-A scores were significantly higher for Group 1 compared to Group 2 during P3 and P4 periods, 1 h after commencement of surgery and completion of surgery, respectively. Conclusion Periodic text messages updating the status of ongoing surgery helps to reduce anxiety for family members of patients undergoing oncological surgery during the intraoperative period. © Indian Orthopaedics Association 2020.Background Many reconstruction methods have evolved to offer limb salvage surgery (LSS) to patients with musculoskeletal sarcomas. It can be achieved using endoprosthesis or biological reconstruction methods like allograft or autograft or a combination of both. In carefully selected patients, resected bone can be recycled and reimplanted after sterilisation using methods like irradiation, autoclaving, pasteurisation or liquid nitrogen. Methods From 2010 to 2016, 10 patients with primary musculoskeletal sarcoma underwent limb salvage surgery (LSS) by wide resection of the tumour and reconstruction using recycled autograft treated with liquid nitrogen. Intercalary resection was carried out in six patients and intra-articular in four. The resected bone was dipped in liquid nitrogen for 25 min, thawed at room temperature for 15 min followed by dipping in vancomycin-mixed saline for 10 min. The recycled bone was re-implanted into its original site and stabilised with internal fixation. Results At a mean follow-up period of 39.6 months (range 6-97 months), all patients had a good function (mean functional score of 80%) with no evidence of local recurrence in the re-implanted bone or otherwise. Union was achieved at 15 of the 16 osteotomy sites with a mean union time of 5.2 months (range 4-7 months) without any additional surgical interventions. In none of the patient, augmentation with vascularised/non-vascularised fibula was done. No complication like fracture of the autograft, implant failure or deep/superficial infection was reported in any patient. Conclusion Recycled tumour-bearing autograft after treatment with liquid nitrogen is an anatomical, cost-effective, relatively simpler and reliable technique for reconstruction of bone defect after resection in selective primary musculoskeletal sarcoma patients. © Indian Orthopaedics Association 2020.Background CT-guided percutaneous drill resection (PDR) for osteoid osteoma fell out of vogue with the advent of radiofrequency ablation (RFA). However, the routine use of RFA is offset by its high cost and need for specialized instrumentation. Aims and objectives This study is an analysis of our series of patients treated with PDR, to know its efficacy, safety and cost-effectiveness. Materials and methods This study is a retrospective analysis of prospectively collected data of 33 patients with a mean age of 10.03 years (2-21 years 1310 MF). The proximal femur was the commonest location, followed by shaft femur, tibial shaft, pubic ramus and lateral humeral condyle. Three were recurrences. The procedures were performed by one of four fellowship-trained paediatric orthopaedic surgeons, using a standard protocol with the help of a radiologist. CT-guided drilling was performed under sedation/short general anaesthesia using a guidewire for identification, followed by sequential drilling using a 6.5 mm cannulated drill or a triple ream drill. Patients were hospitalized overnight for pain relief and allowed protected weight bearing as per pain tolerance. They were evaluated weekly for 2 weeks and 3 monthly thereafter. check details Results The mean final follow-up was 19.72 months (6 months to 58 months). All patients had complete resolution of symptoms within 3 days of the procedure. There were no major complications and there were two minor complications (haematoma and cutaneous hypoaesthesia). There were no recurrences till the last follow-up. Conclusion This study, one of the first and largest from India about CT-guided PDR, shows that this method can still be safely and effectively used as a primary treatment modality in OO, especially in economically challenged population. It is much more cost-effective than RFA, can be used even for recurrent tumours and can be safely be performed by a general orthopaedic surgeon without any special instrumentation. © Indian Orthopaedics Association 2020.
