Bony callus stiffness indirectly evaluated by the axial load-share ratio in vivo as a guide to removing a monolateral external fixator safely. [PDF]
Int Orthop, 2021 Abstract Purpose As the monolateral external fixator is increasingly used in trauma-control and definitive management for high-energy long bone fractures, timing the fixator removal remains a challenge for surgeons. The purpose of this study was to determine the feasibility and effectiveness of the bony callus stiffness ...

Morphology of bony callus growth in healing of a sheep tibial osteotomy [PDF]
Injury, 2021 Long bone fractures typically heal via formation of an external callus, which helps stabilise the bone fragments. Callus composition and morphology influence the mechanical environment, which in turn regulates the progression of healing. Therefore characterising callus development over time is crucial in understanding this mechanobiological regulation.

Measurement of the dynamic axial load-share ratio in vivo could indicate sufficient callus healing in external fixators [PDF]
BMC Musculoskeletal DisordersBackground Fracture healing is commonly evaluated through physical examination and radiographic results. However, these methods rely on the surgeons’ subjective experience, without including the objective biomechanical properties of the bony callus. This

HD-NET: Humerus deep-net for humerus fracture and bony callus formation analysis [PDF]
, 2023 When employing x-ray images, fracture identification in orthopaedics is a difficult task. A large percentage of humerus fracture patients are seen in hospitals, particularly in their emergency departments. Similar to this, after a fracture, accurate callus production monitoring is crucial for bone healing.

Utility of ultrasound imaging in monitoring fracture healing in rat femur: Comparison with other imaging modalities [PDF]
Bone ReportsObjective: Fractures are common injuries and various imaging modalities are employed to diagnose and monitor bone union. However, the follow-up of fracture healing using ultrasound imaging (US) remains a topic of debate.

Fully automated segmentation of callus by micro-CT compared to biomechanics
Journal of Orthopaedic Surgery and Research, 2017 Background A high percentage of closed femur fractures have slight comminution. Using micro-CT (μCT), multiple fragment segmentation is much more difficult than segmentation of unfractured or osteotomied bone.

A novel strain-based bone-fracture healing algorithm is able to predict a range of healing outcomes [PDF]
Frontiers in Bioengineering and BiotechnologyFracture healing is a complex process which sometimes results in non-unions, leading to prolonged disability and high morbidity. Traditional methods of optimising fracture treatments, such as in vitro benchtop testing and in vivo randomised controlled ...

Estudo experimental dos efeitos da heparina de baixo peso molecular (Enoxaparina) na formação de calo ósseo em fêmures de ratos The effects of low-molecular-weight heparin (Enoxaparin) on bony callus formation in rats' femurs - an experimental study [PDF]
Acta Ortopédica Brasileira, 2006 O tromboembolismo venoso é uma complicação grave que pode ocorrer após fraturas. O tratamento anticoagulante mais utilizado é com a heparina de baixo peso molecular (HBPM).
