I'd go 4x a week to get the volume in.
I'd also lower the amount of exercises, but bump up the number of sets, something like -
Alternating weekly Squats or Deadlifts 3-4 sets of five - 6.
Alternate weekly incline or flat bench - 3 x 5, 1 x 10 - 12, the high rep back off set to help hold size.
Wide grip chins - 3 x 6 - 8, 1 high rep set.
Press out of rack - 3 x 5 or 6.
Straight Barbell curls 2-3 x 6-10
I'd probably throw in a couple of sets of pullovers or similar here too.
Till I knew it was healed, I'd play every thing by feel, especially the pressing movements.
