Denis, who recently celebrated his 84th birthday, suffered a fall on Spring Road, which runs at the back of the Wilko's and Tesco superstores.
He and a friend were on their way for a drink at the William Peverel pub on Main Street.
They walked from Highbury Road along the footpath on one side of Spring Road as far as the bottom of a hill, where the pavement suddenly ends.
Denis said: "I tried to take advantage of a gap in the traffic but stumbled and fell forward all my length, banging and cutting my head on the road.
"My pal called for an ambulance and a kindly passer-by rushed to the nearby Royal Oak pub to get tissues for my wound.
"The outcome was that I spent six hours in Queen's Medical Centre, Nottingham, but I am now on the mend.
"It was my second fall at this same spot and I believe a crossing is needed there because, as well as being an access road for the superstores, Spring Road has become a busy route in its own right as a bypass for Bulwell town centre.
"If people are not supposed to use the footpath from Highbury Road, there should be a sign to say so."
Coun Jane Lakey (Lab, who represents Bulwell on Nottingham City Council, said she was sorry to hear that Denis had suffered such a nasty fall but added she was unsure how feasible a crossing would be at that point.
She said: “That back road is principally an access road for vehicles leading to a number of car parks.
"The aim is that pedestrians walk into Bulwell and access the shops through the front entrances.
"I don't think it would be possible to make a crossing where there isn't a path.
"It sounds as if it would involve construction of an extended path too.
"The partial path, I agree, is not helpful and perhaps gives the impression that this is a walkway.
"I will raise the issue with the highways department, to get an opinion and see if some proportional safety measures are needed."
