To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

We report a retrospective study over a 15-year period, between 2005 and 2020, evaluating clinical and functional outcomes in patients who underwent reconstruction of the distal radius with an endoprosthetic replacement following excision of both malignant and aggressive benign bone tumours. Data was collected retrospectively from a prospectively maintained electronic database, and prospectively via telephone patient consultation. Musculoskeletal Tumour Society and patient-rated wrist evaluation scores were assessed at a minimum of 1 year postoperatively. Of nine implants, five were arthrodeses and four were arthroplasties. One patient required amputation within 6 months for proximal metastatic disease. At last follow-up, eight patients subjectively reported good function. Five patients returned to high functionally demanding jobs. Mean Musculoskeletal Tumour Society and patient-rated wrist evaluation scores were 72% and 50/100, respectively. We conclude that distal radius endoprosthetic replacements offer acceptable functional outcomes and remain a viable option when biological reconstruction is not possible. Level of evidence: IV
