Internal fixation is associated with less initial operative trauma but has an increased risk of re-operation on the hip. Definite conclusions cannot be made for differences in pain and residual disability between the two groups. Future studies should concentrate on better reporting of final outcome measures and function. There is still a need for studies to define which patient groups are better served by the different treatment methods.
Social function after cervical hip fracture. A comparison of hook-pins and total hip replacement in 47 patients.
47 patients with a cervical hip fracture Garden 3 or 4 and fully ambulatory before the fracture, were randomized to either fixation with Hansson hook-pins (24 patients, median age 79 years) or to a Charnley hip replacement (23 patients, median age 80 years). The patients were followed for 2 years. Social function was evaluated using a standard questionnaire. There were no postoperative deaths and no significant differences in hospital stay. 9/24 patients treated with hook-pins developed healing complications and 2 dislocations occurred in the THR group. After 1 and 2 years, fewer patients treated with hip replacement used outdoor walking aids; they were also more likely to do their own shopping. Hip replacement is a good choice when treating healthy older people with displaced cervical hip fractures, when primary mortality is expected to be low and the risk of healing complications after nailing is high.
