Method & Evidence

AimTo establish a reliable and reproducible MRI imaging protocol for the anterior oblique ligament (AOL) of the thumb's trapeziometacarpal joint (TMC) to aid in the early identification of conditions leading to degenerative arthritis.
MethodExperimental validation using cadaver specimens and expert review.
ProcedureCadaver specimens were initially assessed via X-ray by three hand surgeons. Subsequently, MRI scans were performed using a specific protocol designed to capture images of the obliquely oriented thumb and its ligaments. Following the initial MRI, the specimens underwent dissection to expose and tag the AOL. The specimens were then rescanned using the same protocol, and the pre- and post-dissection images were compared. Open dissection and ligament tagging served as a ground truth to confirm the visualized structures.
ContextMedical imaging and anatomical research, specifically focusing on the thumb's trapeziometacarpal joint.

Variables

IVMRI imaging protocol (specific technique used).
DVReliability and reproducibility of visualizing the anterior oblique ligament (AOL).
CVType of MRI machine, wrist coil, cadaver specimens, dissection procedure.

Strengths & Limitations

Strengths

  • +Inclusion of multiple expert raters (three hand surgeons).
  • +Validation against direct anatomical dissection.

Limitations

The use of cadavers means the results might differ in live patients due to tissue elasticity and movement. The number of surgeons involved in rating was small.

Reliability & validity

Reliability was assessed through the reproducibility of the MRI protocol and expert ratings. Validity was established by comparing MRI findings to direct anatomical dissection.

Think critically

How might the limitations of using cadaver specimens affect the generalizability of these findings to a clinical setting with living patients?
