Abstract
1. A series of 102 cancellous strip grafts for delayed union of long bone fractures has been reviewed.
2. Half of the initial injuries were open.
3. Half of the fractures were butterfly or segmental lesions or were comminuted.
4. After strip grafting 84 per cent of the fractures were united within sixteen weeks, and only four took longer than twenty weeks.
5. Complete failure of union occurred in only one case, a tibial fracture complicated by low-grade pyocyaneus osteomyelitis.
6. A more aggressive attitude to the problem of delayed union is advocated.
