Risk of having surgical complications after a hip fracture surgery may increase in any of the following cases such as Parkinson's disease, osteoarthritis, rheumatic diseases, alcoholism and mental health disorders. In a Finnish nationwide study, 4.6% of all hip surgery patients and 10% of total hip replacement surgery patients faced surgical complications within three months after their surgery.
The study was carried out in collaboration between researchers from the University of Eastern Finland, Kuopio University Hospital, the University of Helsinki and the Finnish National Institute for Health and Welfare.
Approximately 7,000 hip fractures are treated in Finland every year, and the number is expected to grow as the population ages. Post-operative surgical complications weaken the outcomes of treatment and lead to increased costs.
The analysis shows that the treatment of hip fracture is associated with a significant risk of surgical complications. 4.6% of patients experienced surgical complications within three months following their surgery. According to the researchers, the high prevalence of complications can largely be explained by the high age of patients and their comorbidities.
The risk of surgical complications was elevated in patients with osteoarthritis, Parkinson's disease, a rheumatic disease, alcohol dependence, depression or a psychotic disorder.
"Special attention needs to be paid to the treatment of hip fracture in patients who suffer from these diseases," says orthopaedic surgeon Tero Yli-Kyyny, the first author of the article.
Total hip replacement surgery was associated with more surgical complications than other treatment methods, with 10% of total hip replacement surgery patients experiencing a complication. The risk of complications also grew if surgery was delayed.
"For a hip fracture patient, a total hip replacement results in an excellent functional outcome. However, there are surprisingly many complications associated with its use. It seems that careful selection of patients is required when treating their hip fracture with a total hip replacement," Professor Heikki Kröger from the University of Eastern Finland says.
The study was the first nationwide register-based study to focus on early post-operative complications in the treatment of hip fracture. Similar observations of the prevalence of complications have earlier been made in hospital-specific studies. The large set of data used in the study allowed for entirely new observations relating to, e.g., the increased risk of complications in people with Parkinson's disease.
