Trapezium Bone Density—A Comparison of Measurements by DXA and CT [PDF]

Journal of Functional Biomaterials, 2018
Bone density may influence the primary fixation of cementless implants, and poor bone density may increase the risk of implant failure. Before deciding on using total joint replacement as treatment in osteoarthritis of the trapeziometacarpal joint, it is

Bipartite trapezium – rare congenital accessory bone: a case report of two bilateral cases among related patients and description of new accessory bone – os scaphocapitatum anterius [PDF]

BMC Musculoskeletal Disorders
Background Trapezium typically maintains consistent morphology, and its anatomical variants are rare. We present the first known familial cases of multiple accessory carpal bones, including bipartite trapezium, and a previously undescribed volar ...

Two-stage management of traumatic comminuted trapezium fracture with severe bone defect: a case report and literature review [PDF]

BMC Musculoskeletal Disorders
Background Trapezium fractures are rare carpal injuries, and comminuted intra-articular patterns with severe bone loss are exceptionally uncommon and challenging, with no established consensus; patient-specific 3D printing may offer a reconstructive ...

Influence of differences in bone morphology on the distribution patterns of subchondral bone density across the trapeziometacarpal joint

Scientific Reports, 2022
We aimed to clarify the effects of morphological patterns of the trapezium and first metacarpal on the distribution of subchondral bone density across the articular surface of the trapeziometacarpal (TMC) joint using computed tomography ...

Venous-trapezium coupler anastomosis in a partially congested combined ALT/TFL-flap: A case report [PDF]

JPRAS Open
Background: Reconstruction of large soft tissue defects with extensive vascular trauma remains a challenge. Intraosseous cannulation, commonly used in emergency medicine, may offer a novel solution for venous outflow.

Traumatic Dorsal Dislocation of the Trapezium: Surgical Management of a Rare Hand Injury. [PDF]

Cureus
Isolated dorsal dislocation of the trapezium is an exceptionally rare carpal injury, typically secondary to high-energy trauma, and carries a high likelihood of being overlooked during the initial radiographic evaluation.

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus. [PDF]

J Anat
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.
