My mum is a rehab nurse on a ward for people that have fallen and fractured/broken their hip!! They are usually rehabilitated within 6 weeks and fit enough to go home within 6 weeks.
It sounds like your mum will be up and about in this time!! You say she is a usually fit and active person?? This is a deffo plus as to her recovery time Bernie. I know it is easier said than done, but try not to worry, she sounds fit as a fiddle other than the hip

She will be back on the old pins before you know it
