A Proposal for a New Classification of the Supernumerary Heads of the Biceps Brachii Muscle.

Introduction: The anterior compartment of the arm consists of three muscles: the biceps brachii (BB), brachialis, and coracobrachialis muscle. The aim of the present study was to characterize possible variations in the supernumerary heads of the biceps brachii and use these to prepare an accurate classification of the area that could be used for planning surgical procedures in the region. .

The relationship between additional heads of the quadriceps femoris, the vasti muscles, and the patellar ligament.

Introduction: The quadriceps femoris consists of four muscles: the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis. However, the effect of additional quadriceps femoris heads on the vasti muscles and patellar ligaments is unknown. The aims of the present study are to determine the relationship between additional quadriceps femoris heads and the vasti muscles and patellar ligaments and to review the morphology of the vastus lateralis, vastus medialis, and vastus intermedius.

[Rethinking Sciatica In View of a Bilateral Anatomical Variation of the Sciatic Nerve, with Low Origin and High Division: Historical, Anatomical and Clinical Approach].

Introduction: The aim of the present study is to report an original, unusual, case of bilateral anatomical variation of the sciatic nerve, with low origin and high division.

Material And Methods: Anatomical dissection was performed on a 66 year-old female cadaver. The corpse was embalmed and conserved through our original embalming techniques.

An unusual variety of the extensor digiti muscles: report with notes on repetition strain injuries.

In over 500 human cadaveric dissections of arms and forearms, performed to the present date, we find frequent anatomical variations, corresponding to classic descriptions. Last year, we found a singular anatomic variation of the extensor muscles of the forearm, which seems previously undescribed. It is our strong belief that gross anatomy studies, and gross dissection should be updated and reintroduced in modern anatomical studies, for teaching, research, or surgical training purposes.

Sciatic nerve high division: two different anatomical variants.

Introduction: Sciatic nerve variations are relatively common. These variations are often very significant in several fields of Medicine. The purpose of this paper is to present two such variants and discuss their clinical implications.
