Ligamentous constraint of the first carpometacarpal joint

Journal of Biomechanics, 2021
To examine the role of the ligaments in maintaining stability of the first carpometacarpal (CMC) joint, a sequential ligament sectioning study of sixteen specimens was performed. While a small compressive force was maintained, loads were applied to displace each specimen in four directions - volar, dorsal, radial, and ulnar.

Innovative surgical technique for reconstruction of metacarpal in giant cell tumor – A case report

Journal of Orthopaedic Reports, 2022
Background: Giant cell tumor or Osteoclastoma is a rare tumor of bones accounting for less than 5% of all the primary bone tumors. It is extremely rare in small bones of hand. Even in hand, metacarpals are less commonly involved as compared to phalanges.

Ultrasound Findings in Symptomatic HADD of the Hand and Wrist. A Case Series of 37 Patients

Journal of Clinical Ultrasound, EarlyView.
Ultrasound enables accurate diagnosis of hydroxyapatite deposition disease of the hand and wrist in patients with acute, non‐traumatic pain, typically in middle‐aged women. Characteristic calcifications, often in the resorptive phase, support diagnosis, while radiography may confirm findings without the need for advanced imaging.

Discrepancy between Radiographic and Arthroscopic Findings of Thumb Basilar Joint Arthritis: A Preliminary Clinical Report

Plastic and Reconstructive Surgery, Global Open, 2023
Background:. The radiographic staging of arthritic changes in the thumb carpometacarpal (CMC) joint is known to have poor correlation with pain level. This may be due to the limited ability of radiographs to evaluate degenerative changes.

Comparative anatomy of chicken and human forelimb muscles: Implications for human congenital conditions through developmental models

Journal of Anatomy, EarlyView.
The chicken embryo is an accessible, low‐cost and genetically tractable model for studying limb development and congenital limb differences. We directly compared chicken and human limb musculature using published evidence alongside our own data and observations.

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus

Journal of Anatomy, EarlyView.
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.

Osteoarthritis of the base of the thumb: diagnosis and classification

Travmatologiâ i Ortopediâ Rossii
Background. The scapho-trapezio-trapezoidal (STT) and first carpometacarpal (CMC) joints form the base of the thumb, enabling complex actions such as holding, pinching, and precising manipulations, which determine its functional importance. Understanding
