Concomitant variations of the tibialis anterior, and extensor hallucis longus, and extensor hallucis brevis muscles Open
Tibialis anterior (TA) muscle originates from the lateral surface of tibia and its tendon attaches to the medial cuneiform and base of the first metatarsal. The TA muscle is responsible for both dorsiflexion and inversion of the foot. We p…

Update on the Biomechanics of the Craniocervical Junction, Part II: Alar Ligament Open
Study Design: In vitro biomechanical study. Objective: The strength of the alar ligament has been described inconsistently, possibly because of the nonphysiological biomechanical testing models, and the inability to test the ligament with …

Update on the Biomechanics of the Craniocervical Junction—Part I: Transverse Atlantal Ligament in the Elderly Open
Study Design: In vitro biomechanical study. Objective: The transverse ligament is the strongest ligament of the craniocervical junction and plays a critical role in atlanto-axial stability. The goal of this cadaveric study, and the subsequ…

The Petroclinoid Ligament: Its Morphometrics, Relationships, Variations, and Suggestion for New Terminology Open
The anatomy and definition of the petroclinoid ligament (PCL) and its relationship with the abducens nerve are variably described. The goal of this study was to clarify the anatomy of the PCL and better elucidate its relationship with the …

Variant Innervation of the Medial Pterygoid Muscle from the Lingual Nerve Open
During a routine dissection of the infratemporal fossa and lateral face, a branch of the left lingual nerve was observed entering the medial pterygoid muscle. Normally, the nerve to the medial pterygoid is a direct branch from the mandibul…

Case Report of a Pelvic Crossed Fused Renal Ectopic Kidney Open
Herein we present a case of a horseshoe kidney with crossed fused renal ectopia. Both of these pathologies are congenital anomalies; however, to date, there are few cases that present with both. In this case, discovered during routine diss…

Ectopic Pituitary Adenoma Presenting as a Clival Mass Open
Pituitary adenomas are well described in the literature and are frequently observed and treated in clinical practice by neurosurgeons. On the other hand, ectopic adenomas are a diagnostic enigma; a good understanding of anatomy and radiolo…

Ossification of the mamillo-accessory ligament: a review of the literature and clinical considerations Open
Ossification of the mamillo-accessory ligament (MAL) is a misunderstood phenomenon; however, many have posited that it can result in nerve entrapment of the medial branch of the dorsal ramus causing zygapophyseal joint related low back pai…

Ossification of the roof of the porus trigeminus with duplicated abducens nerve Open
Ossification of parts of the intracranial dura mater is common and is generally accepted as an age-related finding. Additionally, duplication of the abducens nerve along its course to the lateral rectus muscle is a known, although uncommon…

A Variant of the Sciatic Nerve and its Clinical Implications Open
Variants of gluteal neural anatomy are important to consider, especially during surgical approaches to the hip. During the routine dissection of the gluteal region, a variant of the sciatic nerve was found where the nerve left the pelvis f…
