  1. DRF= distal radius fracture , DP distal phalanx, = MC= metacarpal, M= multiple , R/U= radius and ulna . UE= upper extremity; Bolding is used to highlight where there was some seasonality indicated i.e. the highest proportion of fractures occurring in a specific quarter of the year with a minimum difference of at least 3% over quartiles from other seasons. A (<=5) is used where the numbers were too small for reporting, but not 0 (a measure taken to protect privacy in small cells of health administrative data)
