Morbidity and mortality after hip fracture: the impact of operative delay.
ABSTRACT The relationship between the timing of surgery after hip fracture and the subsequent survival of the patient has been studied extensively, yet still remains a controversy. This study aims to assess the impact of operative delay on the 1-year survival of patients and on the rate of complications during the postoperative hospital stay.
Medical and demographic data were extracted from the hospital records of 651 consecutive hip fracture patients over 60 years old. Information on mortality was obtained by cross-linkage with the Department of Interior population files. The multivariate survival analysis model was utilized to assess the association between the time from fracture incident to surgery and the outcome (1-year survival and postoperative complications).
The hazard ratio (HR) of 1-year mortality for postponing surgery beyond 48 h was 1.63 (95%CI 1.11-2.40), as derived by the Cox proportional hazards model. Other variables found to be independently associated with decreased survival are: male gender (HR=1.54), mental deterioration (HR=2.94), postoperative mobility (HR=2.45), and severity of pre-existing diseases (HR=1.96). Occurrence of general complications during the postoperative hospital stay was a significant predictor of decreased 1-year survival (HR=1.83).
These findings suggest that early (within 48 h) surgical treatment of hip fractures is associated with improved 1-year survival.
Article: Initial promising results of the dynamic locking blade plate, a new implant for the fixation of intracapsular hip fractures: results of a pilot study.[show abstract] [hide abstract]
ABSTRACT: The osteosynthesis of intracapsular hip fractures results in a 19-48% failure rate. Only when the anatomical reduction is secured by stable fixation, revascularisation of the femoral head can take place and the fracture can heal by primary osteonal reconstruction. The common implants lack rotational and/or angular stability. Also the relative large volume of the implants within the femoral head compromises the (re)vascularisation. The combination of an anatomical reduction and a low volume, dynamic implant, providing angular and rotational stability seem to be crucial factors in the treatment of intracapsular hip fractures. This assumption formed the starting point for the development of the dynamic locking blade plate (DLBP), a new implant for the internal fixation of intracapsular hip fractures. This report describes the first clinical results of the new implant. Internal fixation with the DLBP was performed in 25 consecutive patients with an intracapsular hip fracture within 24 h from admission. Failure of fixation, due to non-union, avascular necrosis, implant failure or secondary displacement of the fracture, was the primary outcome measurer. Functional outcome was assessed by the Harris Hip Score. Following internal fixation of intracapsular hip fractures with the DLBP, a failure rate of 2 out of 25 patients and excellent functional results were seen after a follow-up of more than 2 years. The initial clinical results of the DLBP are promising and justify the start of a randomised controlled trial.Archives of Orthopaedic and Trauma Surgery 10/2010; 131(4):519-24. · 1.37 Impact Factor

ABSTRACT: The effect of delay of surgery on the geriatric hip fractures has been a subject of interest in the past two decades. While the elderly patients will not tolerate long periods of immobilization, it is still unclear how soon these surgeries need to be performed. A review of existing literature was performed to examine the effect of timing of surgery on the different outcome parameters of these patients. Although there is conflicting evidence that early surgery would improve mortality, there is widespread evidence in the literature that other outcomes including morbidity, the incidence of pressure sores, and the length of hospital stay could be improved by shortening the waiting time of hip fracture surgery. We concluded that it is beneficial to the elderly patients to receive surgical treatment as an urgent procedure as soon as the body meets the basic anesthetic requirements.Osteoporosis International 12/2010; 21(Suppl 4):S529-34. · 4.58 Impact Factor
Article: Pressure Ulcers and Prolonged Hospital Stay in Hip Fracture Patients Affected by Time-to-Surgery[show abstract] [hide abstract]
ABSTRACT: Background:Hip fractures are associated with high morbidity. Pressure ulcer formation after hip surgery is often related to delayed patient mobilization. The objectives of this study were to determine whether time-to-surgery affects development of pressure ulcers postoperatively and, thus, length of hospital stay. Patients and Methods:We performed a retrospective analysis of consecutive hip fracture patients, aged 60 years and above, who underwent surgery between 1995 and 2001. The primary outcome was in-hospital development of pressure ulcers. The secondary outcome measure was the overall length of hospital stay. Analyses were adjusted for relevant confounders. Results:Of the 722 patients enrolled, 488 patients (68%) received surgery at 12 h after admission. Approximately 30% (n = 214) developed pressure ulcers during admission, whilst 19% of patients operated within 12 h of admission developed pressure ulcers. Time-to-surgery was an independent predictor of both development of pressure ulcers (OR = 1.7, 95% confidence interval [CI] = 1.2–2.6; p = 0.008) and length of hospital stay (11.3 vs 13.3 days in the early and the late surgery group, respectively, p = 0.050). Furthermore, development of pressure ulcers was associated with prolonged postoperative hospital stay (19.5 vs 11.1 days for patients with and without pressure ulcers, respectively, p = 0.001) Interpretation:In hip fracture patients, time-to-surgery was an independent predictor of both postoperative pressure ulcer development and prolonged hospital stay. These data suggest that the implementation of an early surgery protocol following admission for hip fractures may reduce both the postoperative complications and overall hospital stay.European Journal of Trauma and Emergency Surgery 04/2012; 33(3):238-244. · 0.33 Impact Factor
