The distal dorsal intermetacarpal ligament: characterization of an overlooked structure —an anatomical study of 25 hands
ConclusionAll dissections revealed a tense ligamentous structure between each metacarpal head of the long fingers. This was a constant structure meeting the definition of a ligament. The distal dorsal intermetacarpal ligament seems to stabilize the metacarpal heads at the second and fourth spaces by limiting hyperabduction. (Source: Surgical and Radiologic Anatomy)

Considerations on the origin of the inferior thyroid artery emerging from the subclavian artery determined by CT examination
ConclusionsThe inferior thyroid artery is one of the arteries most susceptible to variations in terms of origin and size. With differences between the two sides (right and left), as well as differences related to gender. (Source: Surgical and Radiologic Anatomy)

The effect of lifting load on the kinematic characteristics of lumbar spinous process in vivo
ConclusionThe in vivo kinematics of the lumbar spinous process will not change significantly with increasing low load. In complex motion, the spinous process is dominated by coupling motion. (Source: Surgical and Radiologic Anatomy)

Is the radial groove a myth? Is the radial nerve in direct contact with the posterior humerus?
ConclusionThis study shows that the radial groove may not exist and is probably not a true anatomical structure. In addition, the nerve is in direct contact with the posterior periosteum of the humerus in most specimens. These anatomic relationships and findings add to the anatomical understanding of the radial nerve, which helps during operative approaches and fixation of the humerus.

The lymphatic system of the uterine cervix: towards a more precise definition of the drainage routes
ConclusionPhysiological lymphatic drainage of the uterine cervix presents anatomical specificities, depending on the structure studied, anterior or posterior lip of the cervix. Better knowledge of these specificities should allow personalized surgery for each patient. (Source: Surgical and Radiologic Anatomy)

A computed tomography (CT) based morphometric study of superior pubic ramus anatomy among Arabs to determine safe intramedullary pubic rami screw insertion
ConclusionThe results from this study suggest that percutaneous pubic rami screw fixation using the standard 6.5 or 7.3 mm cannulated screw system may potentially be unsafe in female Arab patients. This subset of patients may require alternative non-cannulated screws (3.5–4.5 mm) or plate options. Further, female patients may have a higher risk of acetabular joint penetration, while males have a potentially high er risk of pudendal nerve injury. (Source: Surgical and Radiologic Anatomy)

Scratching in the minefield: using intertriangles line to safely perform anterior petrosectomy
ConclusionsKawase ’s area resembles a minefield, in which every step and manipulation should be considered. A minimal but effective resection of the cranial base is needed to increase safety and decrease morbidity during skull base surgery. Furthermore, this study investigated accessible and prominent landmarks to establish a feasible area of triangles and define the intertriangles line to guide the neurosurgeon under microscope and avoid IAC injury.

Topographical study of scapular foramina and scapular nutrient foramina in dried skeletons
ConclusionUnlike previous studies, the present study suggests that SF are normal anatomical findings, present in 78.0% of the scapulae investigated. Surgeons should be aware of both SNF and SF when operating or interpreting radiological findings. (Source: Surgical and Radiologic Anatomy)

External occipital protuberance classification with special reference to spine type and its clinical implications
ConclusionsPlain lateral radiography is a reliable method to measure the length and thickness of spinous EOP. However, more values of these parameters for morphometry of the EOP spine do not mean more volume of EOP and vice versa. Detailed information regarding the occurrence of occipital spur and its morphology will be of great importance to neurosurgeons, sports, physicians, emergency departments, and radiologists.

Anatomical landmarks for localisation of the anterior ethmoidal artery: a combined radiological and cadaveric (endoscopic) study
ConclusionThe middle turbinate axilla was the most reliable landmark, due to the lack of statistically significant differences according to sex and laterality, and the high inter-rater agreement between measurements. Anatomical knowledge of variations and relationships observed in the present study can be applied to surgeries of the anterior ethmoidal sinus, frontal sinus, and skull base to improve localisation of the anterior ethmoidal artery, preoperatively and intraoperatively, and avoid iatrogenic injury of the vessel.

Moynihan ’s hump of the right hepatic artery in Calot’s triangle: a systematic review and meta-analysis of its incidence and surgical importance
ConclusionA patient with an unusually “small cystic artery” or “large right hepatic artery” is likely to have a “caterpillar hump”. The caterpillar’s hump of the right hepatic artery is subject to rare anatomical variations in its course that increase the risk of incorrect vessel ligation or injury during laparoscopic chol ecystectomy.
