^a It was not possible to determine the minor features relating to prior symptoms, or to determine bilaterality when contralateral imaging was not performed. When a minor feature was present, this related to increased cortical thickening. Poor healing was not mentioned in any electronic health records
^b N/A not applicable
^c Determined by mention of calcium and vitamin D status in the electronic health record, check of serum vitamin D or whether patient was on supplements
^d IM intramedullary nail; DHS dynamic hip screw
^e This fracture was incomplete
^f This patient had sustained a midshaft fracture on the contralateral side 3 years previously
