Emerging basic science concepts in geriatric fracture fixation and patient recovery Open
In recent history, human life expectancy has increased significantly, resulting in a high burden of late-life morbidity and geriatric fractures. Changes to the body as a result of aging, such as degeneration of the bone marrow, osteoblast …

The Benefit of Repairing the Deltoid Ligament in Unstable Ankle Fractures: Patient-Reported Functional Outcome and Radiological Stability Measurements; a Clinical Trial Protocol Open
Background: Suturing the deep posterior deltoid ligament in unstable ankle fractures is novel to established treatment. Some cadaveric and clinical trials support that adding deltoid ligament repair to plating of the lateral fracture will …

The impact on lateral wall fractures by a sliding hip screw device in trochanteric fractures Open
Aims Trochanteric fractures with a reduced lateral wall thickness and a detached lesser trochanter are unstable. These characteristics can lead to failure through a lateral wall fracture after fixation with a sliding hip screw device (SHS)…

Chronic pelvic insufficiency fractures and their treatment Open
Fragility and insufficiency fractures of the pelvis (FFP) and sacrum (SIF) are increasingly prevalent, particularly among the elderly, due to weakened bone structure and low-energy trauma. Chronic instability from these fractures causes pe…

Subsequent fracture risk in Norwegians and immigrants with an index forearm fracture: a cohort study Open
Summary The current study investigated subsequent fracture risk following a forearm fracture in three country of birth categories: Norway, Europe and North America, and other countries. Subsequent fracture risk was modestly higher in Norwe…

Variation in care and outcome for fragile hip fracture patients: a European multicentre study benchmarking fulfilment of established quality indicators Open
Purpose Despite the availability of clinical guidelines for hip fracture patients, adherence to these guidelines is challenging, potentially resulting in suboptimal patient care. The goal of this study was (1) to evaluate and benchmark the…

No benefit of the trochanteric stabilizing plate on loss of fracture reduction in AO/OTA 31-A2 trochanteric fractures Open
Aims Despite limited clinical scientific backing, an additional trochanteric stabilizing plate (TSP) has been advocated when treating unstable trochanteric fractures with a sliding hip screw (SHS). We aimed to explore whether the TSP would…

Non-operative versus operative treatment of suprasyndesmotic ankle fractures: protocol for a prospective, multicentre, randomised controlled trial Open
Introduction Surgery is widely recognised as the treatment of choice for suprasyndesmotic ankle fractures, because of the assumption that these injuries yield instability of the ankle joint. Stability assessment of ankle fractures using we…

Comparing two different orthogeriatric models of care for hip fracture patients: an observational prospective cross-sectional study Open
Introduction Patients with hip fractures are almost always operated with quite extensive surgery and are often frail with a high risk of complications, increased dependency, and death. Orthogeriatric interdisciplinary care has shown better…

Forearm fractures – are we counting them all? An attempt to identify and include the missing fractures treated in primary care Open
An overall small proportion of forearm fractures were registered only in primary care, but it was larger in some areas of Norway. Failing to include fractures exclusively treated in primary care could underestimate the incidence rates in t…
