Article Synopsis
  • New surgical techniques known as transorbital neuroendoscopic surgery have been developed to access the orbit and intracranial cavity, particularly via the superior eyelid route.
  • This study involved performing transorbital endoscopic dissections on 4 cadavers to explore the feasibility of this approach in identifying arterial structures.
  • Results showed that the M1 and M2 segments of the middle cerebral artery could be accessed using a 0-degree endoscope, suggesting this method could offer a new surgical alternative for certain cranial conditions.

Our study aimed to evaluate and compare the changes in ulnar nerve tension and strain at different elbow positions radiologically and mechanically before and after applying the medial K-wire on the supracondylar humerus fracture cadaver model. We used ten fresh frozen cadaver upper extremity specimens to measure strain and tension on the ulnar nerve in 3 different elbow positions: elbow full extension, elbow flexion-forearm supination, and elbow flexion-forearm pronation. We employed Shear wave elastography (Siemens Acuson S3000 USG, 9L4 linear probe) and a microstrain gauge (Microstrain, Inc.

Article Synopsis
  • Distal radioulnar joint (DRUJ) instability is a common issue after injuries, causing chronic pain and limited function, and current single suture button treatments are often inadequate.
  • This study tested whether a double suture button technique could offer better stability than single constructs for DRUJ instability using cadaver models.
  • Results showed the double suture button significantly reduced movement and restored stability across various positions, outperforming the single construct methods.*

The aim of this study is to evaluate the dose‑dependent effect of bee venom (BV) on behavioral functions in rats and the physiological role of leptin in the prefrontal cortex, hippocampus, and amygdala tissues. Adult Sprague‑Dawley male rats were used in the experiments. The rats were divided into three groups of control, 0.

In recent years, childhood overweight and obesity have become a universal public health problem. Obesity may lead to cognitive disorders, depression and anxiety by affecting neuronal processes. Spirulina platensis (SP), a species of microalgae from the Chlorophyceae green algae class, has neuroprotective effects and may reduce body weight.

It has been shown that electromagnetic fields (EMFs) have negative effects on the reproductive system. The biological effects of EMF on the male reproductive system are controversial and vary depending on the frequency and exposure time. Although a limited number of studies have focused on the structural and functional effects of EMF, the effects of prenatal and postnatal EMF exposure on testes are not clear.

Humans are exposed to electromagnetic fields (EMF) from various sources throughout life. Because humans are easily impacted by environmental factors during early development, it is believed that EMF can cause structural and functional changes on the developing brain that may lead to behavioural changes. This paper investigates the impact of EMF exposure and zinc supplementation during the prenatal and postnatal periods on behavioural changes and synaptic proteins in a gender-dependent manner.

Objective: This study aims to investigate the anatomical relationships of the transmuscular portal to its surrounding structures in arthroscopic treatment of superior labrum anterior posterior (SLAP) lesions in a human cadaveric model.

Methods: In this anatomic study, bilateral shoulder girdles of 12 adult formalin embalmed cadavers were used. All cadavers were male, and the mean age was 63.

Exposure to an electromagnetic field (EMF) can have adverse effects on many organs and tissues, including the reproductive system. This study aimed to investigate the effects of EMF exposure during prenatal and postnatal periods on ovarian development in rat offspring. In this study, rat pups born from eight pregnant rats were used.

The aim of this study is to describe the morphology of frontal recess area with its anatomical variations and to reveal if frontal recess morphology and the anatomical variations related to that region have effects on the pneumatization of the frontal sinuses. The frontal sinus and recess morphometry of 136 sides of 68 dry skulls were evaluated on multislice high-resolution computed tomography. The relationships between frontal sinus and frontal recess measurements were analyzed by correlation and linear regression analysis.

Objective: The lateral patellofemoral ligament (LPFL) is part of the lateral retinaculum cut during arthroscopic or open release. We investigated its anatomic and morphometric characteristics.

Materials And Methods: We identified the LPFL insertion point on the condyle in vertical and sagittal planes in 32 adult cadaveric knees.

Purpose: We aimed to define the classification of frontal sinus pneumatization patterns according to three-dimensional volume measurements.

Methods: Datasets of 148 sides of 74 dry skulls were generated by the computerized tomography-based volumetry to measure frontal sinus volumes. The cutoff points for frontal sinus hypoplasia and hyperplasia were tested by ROC curve analysis and the validity of the diagnostic points was measured.

Objective: Intramedullary nailing is the preferred surgical treatment of humerus shaft fractures. The purpose of this study was to investigate the relationship between the bicipital groove and specific anatomical landmarks in achieving correct alignment of the humerus during intramedullary nailing, and to describe these anatomical landmarks.

Methods: Thirty (15 right; 15 left) total upper cadaver extremities were used in this study.

Aim: The aim of this study was to determine whether the sphenovomerine suture (SVS) can be used as a landmark to localize the sphenoidal sinus ostium.

Methods: Endoscopic imaging was done on 152 skulls to identify ostium of the sphenoidal sinus, the SVS, and the articulation of sphenoidal process of palatine bone between the body of the sphenoid and the sphenopalatine foramen. The variables were as follows: (1) the distance between the medial border of the ostium and SVS (DSO-SVS); (2) the angle between them (ASO-SVS); (3) the distance between the inferior border of the ostium and the horizontal line (DSO-HL); (4) the distance between intersection point of the SVS-sphenoidal process of the palatine bone and the medial border of sphenopalatine foramen (DSPF-SVS); and (5) the number of sphenopalatine foramen.

Objective: To show the branching patterns and the anatomic variations of the dorsal nerve of the penis (DNP) along the penile shaft, particularly the relation with the tunica albuginea.

Methods: The penises of 22 adult cadavers were dissected. The number and the diameters of the branches, the presence of anastomoses between the main trunks, the positioning of the nerves before entering the glans penis, and the presence of branches emerging from the body of the DNP and perforating the tunica albuginea were noted and photographed.
