6i. Intermetacarpal Articulations
(Articulationes Intermetacarpeæ; Articulations of the Metacarpal Bones with Each Other)


The bases of the second, third, fourth and fifth metacarpal bones articulate with one another by small surfaces covered with cartilage, and are connected together by dorsal, volar, and interosseous ligaments.
   1
  The dorsal (ligamenta basium oss. metacarp. dorsalia) and volar ligaments (ligamenta basium oss. metacarp. volaria; palmar ligaments) pass transversely from one bone to another on the dorsal and volar surfaces. The interosseous ligaments (ligamenta basium oss. metacarp. interossea) connect their contiguous surfaces, just distal to their collateral articular facets.   2
  The synovial membrane for these joints is continuous with that of the carpometacarpal articulations.   3
 
The Transverse Metacarpal Ligament (ligamentum capitulorum [oss. metacarpalium] transversum) (Fig. 337).—This ligament is a narrow fibrous band, which runs across the volar surfaces of the heads of the second, third, fourth and fifth metacarpal bones, connecting them together. It is blended with the volar (glenoid) ligaments of the metacarpophalangeal articulations. Its volar surface is concave where the Flexor tendons pass over it; behind it the tendons of the Interossei pass to their insertions.   4

About USMLE

The United States Medical Licensing Examination (USMLE) is a three-step examination for medical licensure in the United States. The Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME) sponsors USMLE.
The Three Steps of the USMLE
Step 1 tests the important concepts of basic sciences basic to the practice of medicine. It also places special emphasis on principles and mechanisms underlying health, disease, and modes of therapy. Step 1 ensures mastery of the sciences that provide a foundation for the safe and competent practice of medicine. It also tests the scientific principles required for maintenance of competence through lifelong learning.
Step 2 CK tests the medical knowledge, skills, and understanding of clinical science essential for the provision of patient care under supervision. It also includes emphasis on health promotion and disease prevention. Step 2 CK ensures that due attention is devoted to principles of clinical sciences and basic patient-centered skills.
Step 2 CS tests your capacity to practice and provide good medical service in real-life situations. It also tests your communication skills.
Step 3 tests your medical knowledge and understanding of biomedical and clinical science essential for the unsupervised practice of medicine. Step 3 provides a final assessment of physicians assuming independent responsibility for delivering general medical care.
