Cutaneous Branch of the Spinal Accessory Nerve: Case Report With Potential Relevance to Occipital Neuralgia.

Cureus 2021 Sep 2;13(9):e17666. Epub 2021 Sep 2.

Department of Structural & Cellular Biology, Tulane University School of Medicine, New Orleans, USA.

We describe a case in which a cutaneous branch was found arising from the spinal accessory nerve, a nerve typically characterized as a purely motor nerve. Although reported anatomical variations of the lesser occipital and spinal accessory nerves are uncommon, rare variants have been reported. Such anatomy might result in unexpected patient presentations or rare complications following spinal accessory nerve injury.

Comprehensive review of the incisive branch of the inferior alveolar nerve.

Anat Cell Biol 2021 Oct 8. Epub 2021 Oct 8.

Department of Neurosurgery, Tulane Center for Clinical Neurosciences, Tulane University School of Medicine, New Orleans, LA, USA.

The incisive branch of the inferior alveolar nerve is a vital anatomical structure within the anterior mandible that has not been thoroughly defined and outlined in reports in the literature until recent years. Advances in radiological imaging, particularly the widespread use of cone-beam computed tomography has allowed for accurate visualization of the mandibular incisive canal (MIC) and its associated incisive branch of the inferior alveolar nerve. Surgical damage to the MIC, which could result in hemorrhage and sensory disturbance, may occur in commonly practiced oral and maxillofacial procedures, such as chin bone harvesting, implant placement, fracture repair and removal of pathologic entities of the anterior mandible. Knowledge of both the presence, dimensions and location of the incisive branch is a vital component to pre and peri-operative planning of oral and maxillofacial surgeries performed within the mandible, particularly within the interforaminal zone. In this article, the terminology, anatomy, imaging, surgical consideration, and pathology of the incisive branch will be discussed.

Possible points of compression of the ulnar nerve: tricks and traps that await clinicians from an anatomical point of view.

Clin Anat 2021 Oct 5. Epub 2021 Oct 5.

Department of Anatomical Dissection and Donation, Medical University of Lodz, Poland.

The ulnar nerve can be subject to numerous types of compression. The most common are cubital tunnel and ulnar tunnel syndromes, but there are many others with more uncommon etiologies. The existence of additional communicating branches, median nerve involvement, various types of injuries and unusual anatomical variations can be a challenge for both diagnosis and treatment. This review presents a comprehensive depiction of ulnar nerve entrapment syndromes with particular reference to their anatomical background, risk factors, and clinical evaluation. Even common disorders can result from atypical morphological changes. It is important to be familiar with them as it is a key ability in daily medical practice.

Unknown variant of the accessory subscapularis muscle?

Anat Sci Int 2021 Sep 30. Epub 2021 Sep 30.

Department of Anatomical Dissection and Donation, Medical University of Lodz, Lodz, Poland.

Acting in medial rotation of the arm, the subscapularis (SM) is the most powerful and largest muscle of the rotator cuff. It is morphologically variable, especially in the number of tendons, place of insertion, and number of bellies, and it is sometimes fused with another muscle. An accessory subscapularis muscle (ASM) is among the morphological variations of the SM, but it is a really rare variant. The present case describes a very rare ASM that is divided into proximal tendinous attachment, intermediate fleshy muscular belly and distal tendinous attachment. Its origin is located on the lateral border of the scapula, but some fibers are connected with the muscular part of the SM. Its distal attachment is fused with the capsule of shoulder joint, above the tendinous insertion of the SM. Such an arrangement allows for greater stabilization of the joint. Moreover, there is a possibility that it could be used during treatment of ruptured SM tendons.

Anatomical variation of co-existing bilaminar tensor of the vastus intermedius muscle and new type of sixth head of the quadriceps femoris.

Folia Morphol (Warsz) 2021 Sep 30. Epub 2021 Sep 30.

Department of Normal and Clinical Anatomy, Chair of Anatomy and Histology, Medical University of Lodz, Poland, Łódź.

Background: We present a case report of Quadriceps Femoris (QF) with co-existing bilaminar Tensor of the vastus intermedius muscle (TVI) and new type of sixth head.

Materials And Methods: Cadaveric dissection of left thigh of a 72 years old was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The left lower limb were dissected using standard techniques according to a strictly specified protocol. Each head of the muscle was photographed and subjected to further measurement.

Results: During dissection, an unusual type of TVI muscle was observed. It consisted of two surfaces, superficial and deep. In addition sixth head of QF muscle grew out from the VM muscle.

Conclusions: The knowledge of the existence and possible variations of additional heads of QF muscle is necessary during diagnostic process of muscle strains. Moreover, according to course of tendons that heads may take part in patella stabilization.
