The Three-Dimensional Morphology of Femoral Medullary Cavity in the Developmental Dysplasia of the Hip [PDF]

Frontiers in Bioengineering and Biotechnology, 2021
ObjectiveThis study aimed to assess the morphology of the femoral medullary canal in subjects with developmental dysplasia of the hip (DDH) with the intent of improving the design of femoral stems in total hip arthroplasty.MethodsComputed tomography ...

Injectable in-situ curable hydrogel for medullary cavity hemostasis [PDF]

Frontiers in Bioengineering and Biotechnology
Achieving hemostasis in the narrow and elongated medullary cavity is a challenge in bone hemostasis. This study developed an in-situ hemostatic hydrogel based on the Schiff base reaction principle, which was cross-linked by the aldehyde groups of ...

Monte Carlo-based in-depth morphological analysis of medullary cavity for designing personalized femoral stem [PDF]

Frontiers in Surgery
BackgroundThe design of femoral stem prostheses requires a precise understanding of the femoral marrow cavity. Traditional measurements of morphological parameters in the upper femur, particularly the medullary cavity and cortical region, are primarily ...

Anatomical structure of the medullary cavity of proximal femur with three-dimensional computed tomography [PDF]

BMC Musculoskeletal Disorders
Background The lateral femoral wall is an important anatomical parameter of the proximal femur, but intramedullary nail fixation for intertrochanteric fractures may cause iatrogenic lateral wall fractures due to population-based design differences.

Capacity of the medullary cavity of tibia and femur for intra-bone marrow transplantation in mice. [PDF]

PLoS One, 2019
Intra-bone marrow transplantation (IBMT) has been adapted for mouse models to improve the seeding efficiency of transplanted hematopoietic stem and progenitor cells. Commonly used injection volumes for IBMT into the tibia differ between 10 and 40 μL even though considerable amounts of injected cells leak into the blood circulation immediately after ...

Bizarre parosteal osteochondromatous proliferation in the distal ulna where the lesion is continuous with the medullary cavity: a case report [PDF]

BMC Musculoskeletal Disorders
Background Bizarre parosteal osteochondromatous proliferation (BPOP) is a rare benign bone tumor, it is also called “Nora’s lesion”. The lesion is characterized by heterotopic ossification of the normal bone cortex or parosteal bone. The etiology of BPOP

Classification of diaphyseal tumors based on residual medullary cavity length for prosthetic reconstruction [PDF]

Scientific Reports
Diaphyseal prosthetic reconstruction for bone tumors continues to face challenges with failures due to the lack of evidence-based classification systems. This study aimed to develop and validate a novel classification framework to optimize reconstruction

Is there a true match in the femoral medullary cavity between neutral and flexion alignment of the stem on a female (Asian) population? [PDF]

BMC Musculoskeletal Disorders
Background In total hip arthroplasty, stem alignment has been proposed to occur in the neutral and flexed positions. Nonetheless, there is a paucity of research on the relationship between the shape of the medullary cavity cross-section and its ...

Microstructural Variations in the Bone of Pygoscelis antarctica (Aves, Sphenisciformes) During the Postnatal Ontogeny [PDF]

Biology
Ontogenetic changes in bone microstructure provide key information on growth patterns and functional differentiation in birds. This study describes microanatomical and histological variation in the appendicular and axial skeleton across an ontogenetic ...

Medullary cavity expansion is mediated by distinct cell populations during fetal bone development [PDF]

Nature Communications
Bone marrow (BM) is the primary site of postnatal hematopoiesis, yet how it is established during embryogenesis remains poorly understood. BM formation is initiated by the invasion of vascular and mesenchymal cells into a preformed cartilage template ...
