Risk of suprascapular nerve injury in open Trillat procedure: an anatomical study
ConclusionDuring the open Trillat Procedure, the SSN can be injured due to its anatomical location. Placement of the screw should be within 10 ° of the glenoid plane to minimize the risk of SSN injury and could require the use of a specific guide or arthroscopic-assisted surgery.

The effect of hallux valgus on the anatomy of the nerves around the first metatarsal bone
ConclusionSex differences in the distance of the nerves to the EHL disappeared when the size effect of the cross-section of the first metatarsal bone region was eliminated with the clock model. Only in advanced HVA (>20 °) (not in mild HV), the DFN being closer to the EHL distally and the intersection of the medial branch of the MDCN with the EHL in HV being more proximal than in normal can be interpreted as specific reflections of HV progress. The variations we revealed in the number of branches reaching the insi de of the foot may explain the diversity of neuromas or nerve injuries associated with HV surgery. (Source...

Correlation of maximal nasal septal deviation with deviation at the maxillary insertion
ConclusionOur data reveal a positive correlation between septal deviation at the floor of the nose and overall septal deviation; this was not observed at the septal deviation at the roof. This could be explained due to the inherent tilt in the cribriform plate or by earlier ossification and fixation of the septum during its development at its insertion to the roof, thereby allowing further growth and potential for deviation of the lower part of the septum and its insertion to the floor.

3D anatomy of the supraorbital and greater occipital nerve trajectories
ConclusionThe study introduces a novel 3D methodology for analyzing the SON and GON, highlighting considerable anatomical variation. Understanding this variability is crucial for clinical applications and tools targeting the skull innervation. The findings serve as a valuable reference for future research, emphasizing the necessity for personalized approaches in innervation-related interventions. (Source: Surgical and Radiologic Anatomy)

Unilateral identification of a rare superficial brachioulnoradial artery contributing to the superficial palmar arch and brachial artery continuing as the interosseous artery: a case report
AbstractThe occurrence of variations in human arterial branching of the upper limb has been commonly reported in peer-reviewed literature. However, the variability of upper limb arterial patterns may be underappreciated in medical practice, which can result in clinical and surgical errors. Here we report a case of a rare, unilateral arterial variation of the left upper limb of a 76-year-old Caucasian male cadaver, discovered during a routine educational dissection. Observed characteristics of the variation include a high brachial artery bifurcation into a superficial brachioulnoradial artery and brachial artery continuing ...

Composition of encephalic arteries and origin of the basilar artery are different between vertebrates
AbstractIntracranial arterial anatomy is lacking for most mammalian and non-mammalian model species, especially concerning the origin of the basilar artery (BA). Enhancing the knowledge of this anatomy can improve animal models and help understanding anatomical variations in humans. We have studied encephalic arteries in three different species of birds and eight different species of mammals using formalin-fixed brains injected with arterial red latex. Our results and literature analysis indicate that, for all vertebrates, the internal carotid artery (ICA) supplies the brain and divides into two branches: a cranial and a c...

Tibial nerve branching pattern and compatibility of branches for the deep fibular nerve
ConclusionIn today drop foot is very common. Traditional methods of treatment are insufficient. Nerve transfer is viewed as an application that can both improve patient outcomes and hasten the patient ’s return to society. The nerve of the soleus muscle was shown to be the best candidate for transfer in our investigation. (Source: Surgical and Radiologic Anatomy)

Anatomy of the temporal region to guide filler injections
AbstractHollow temples are not typically considered aesthetically pleasing, and hollowness worsens with the aging process. When filling this region with fillers, there are several anatomical considerations, with injection techniques varying depending on the layer targeted. Specifically, injections between the superficial temporal fascia and the superficial layer of the deep temporal fascia are performed using a cannula, while periosteal layer injections involve the use of a needle to reach the bone before inserting fillers. Detailed anatomical insights encompass the boundaries of the temporal fossa and cautionary notes reg...

Hypertrophied medial parapatellar plica: a case of a medial plica anatomical variation with insertion to the inter-meniscal ligament in an adolescent athlete treated arthroscopically
ConclusionsThis study presented a rare anatomical variation of a hypertrophied medial parapatellar plica with atypical course in the medial patellofemoral compartment and insertion into the inter-meniscal ligament. In combination with a medial meniscus tear led to a locked knee. Arthroscopic medial meniscus repair and plica excision resulted in complete resolution of symptoms.

Renal vein valves: a prevalence, microanatomical and histological study
ConclusionOn the basis of our study, RVV are not uncommon. They were more common on left sides, and on both sides, they were found within approximately one centimeter of the junction of the inferior vena cava and renal vein. Although the function of such valves cannot be inferred from this anatomical study, the structures of the Single leaflet valve (TS2) and Double leaflet valve (TS3) valves suggest they could prevent venous reflux from the IVC into the kidney.
