Subject: Femoral Neck Nonunion
A miner 38 y.o. referred to us with 5 months old femoral neck lesion - after direct impact by a heavy construction he probably had non-displaced neck fracture. 3 months of spica cast, then non-weight-bearing. AP view and CT scan attached. Looks like AVN is present. ROM is painless and full, loading is also painless.
What would be optimal for the case? Osteotomy - McMurray or valgus? Osteosynthesis with core decompression? THR? Something else?.

recommend Valgus osteotomy as reported by Marti et al JBJS Br 1989
AVN was not necessarily related to a poor functional outcome

I agree with Marc- this is what I have been doing. There is the option of a free vascularized fibular graft. There has been at least one report by the Duke group (not published yet) of 20 patients with femoral neck nonunion that have been treated with success in this manner. It doesn't change the mechanics of the hip or gait and allows for easier revision to Total hip arthroplasty.
