Background: Hindfoot endoscopy is an effective treatment for posterior ankle impingement syndrome (PAIS) and flexor hallucis longus (FHL) tendon disorders. However, FHL tendoscopy, especially from the posteromedial portal, carries a risk of tibial nerve damage. A needle-arthroscopic system with a 1.

A vascularized free fibula flap is often used to reconstruct bone defects. However, bone resorption within the osteotomized segment is often observed. This may be attributed to damage to bone blood flow supplied by nonpenetrating periosteal vessels (NPPVs); however, there are few studies on NPPVs in the fibula.

Objectives: To describe a novel technique for dissecting cadaver brains without damaging medial brain structures and surfaces, ensuring preservation for neuroanatomical study and training.
Methods: Ten adult cadaveric brains were dissected using the supracerebellar suprapineal approach under an operative microscope with 6x to 40x magnification. This approach allowed for the separation of the brain into two hemispheres while providing direct visualization of the third ventricle and preserving midline structures.

: the mandibular foramen is an essential anatomic landmark in performing various dental and surgical procedures, including inferior alveolar nerve block (IANB). However, its position may vary based on the individual morpho-functional features of the skull and face. This study aims to conduct a personalized assessment of the location of the mandibular foramen in various shapes of skulls, faces, and mandibles.

Osteoarthritis is caused by damage to the articular cartilage due to bone-on-bone collisions and friction. The length, width, and thickness of the ligaments are expected to change in order to regulate excessive bone-to-bone movement. We aimed to clarify the relationship between ligament morphology and joint surface degeneration in the ankle joints using macroscopic observations and measurements.
