The current hospital costs of treating hip fractures.

Hip fractures impact heavily on our health service resources yet there is no recent United Kingdom study detailing hospital costs for such injuries. A comprehensive analysis of 100 patients admitted with a hip fracture was performed to determine current medical expenditure incurred during acute hospitalisation for hip fracture during 2003. Costs associated with surgery (implant and theatre costs) and laboratory/radiological investigations were established from individual use. The mean stay of the study group (mean age 83 years, 77 females and 23 males) was 23 days. The mean total hospital expenditure per patient was calculated to be 12,163 pounds sterling of which ward costs contributed 84%, operative costs 9% and investigations 7%. These results emphasise the growing economic impact arising from the inpatient treatment hip fractures, most of which relate to length of hospital stay.

Early mortality after hip fracture: is delay before surgery important?

BACKGROUND: Hip fracture is associated with high mortality among the elderly. Most patients require surgery, but the timing of the operation remains controversial. Surgery within twenty-four hours after admission has been recommended, but evidence supporting this approach is lacking. The objective of this study was to determine whether a delay in surgery for hip fractures affects postoperative mortality among elderly patients. METHODS: We conducted a prospective, observational study of 2660 patients who underwent surgical treatment of a hip fracture at one university hospital. We measured mortality rates following the surgery in relation to the delay in the surgery and the acute medical comorbidities on admission. RESULTS: The mortality following the hip fracture surgery was 9% (246 of 2660) at thirty days, 19% at ninety days, and 30% at twelve months. Of the patients who had been declared fit for surgery, those operated on without delay had a thirty-day mortality of 8.7% and those for whom the surgery had been delayed between one and four days had a thirty-day mortality of 7.3%. This difference was not significant (p = 0.51). The thirty-day mortality for patients for whom the surgery had been delayed for more than four days was 10.7%, and this small group had significantly increased mortality at ninety days (hazard ratio = 2.25; p = 0.001) and one year (hazard ratio = 2.4; p = 0.001). Patients who had been admitted with an acute medical comorbidity that required treatment prior to the surgery had a thirty-day mortality of 17%, which was nearly 2.5 times greater than that for patients who had been initially considered fit for surgery (hazard ratio = 2.3, 95% confidence interval = 1.6 to 3.3; p < 0.001). CONCLUSIONS: The thirty-day mortality following surgery for a hip fracture was 9%. Patients with medical comorbidities that delayed surgery had 2.5 times the risk of death within thirty days after the surgery compared with patients without comorbidities that delayed surgery. Mortality was not increased when the surgery was delayed up to four days for patients who were otherwise fit for hip fracture surgery. However, a delay of more than four days significantly increased mortality.

Results of dynamic condylar screw for subtrochanteric fractures.

A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. The mechanism of injury was low-energy in 47 cases and high-energy in 11 cases. Five patients died before fracture healing. Ten out of 11 young patients, (nine with high-energy injuries), united primarily. In contrast, the primary union rate in the elderly was 74%. Implant failure was seen in 11 cases (20%). Restricted weight bearing status post-operatively was associated with significantly lower incidence of implant failure (P<0.05, chi(2)-test). The use of bone graft was not related to fracture union (P>0.5). After revision surgery the overall union rate in the elderly was 90%. Using the DCS, the results were good in the young patients with high-energy injuries. However, the implant failure rate is high in elderly patients who suffer low-energy fractures. The DCS should not be used if weight bearing cannot be minimized in this group.
