Fibular notch morphometry and its clinical importance on dry bones.

The aim of the present study was to determine the morphometric characteristics of the fibular notch (FN). This study was carried out with 76 dry adult tibial bone specimens (right 38, left 38) with unknown age and sex collected from the Department of Anatomy, Cukurova University, Adana. The mean width of the FN was 23.04 ± 2.02 mm; the mean depth of the FN 3.63 ± 0.83 mm; the mean height of the FN was 41.76 ± 4.01 mm. The mean anterior facet length and posterior facet length was found to be 10.44 ± 1.94 mm and 13.93 ±1.63 mm, respectively. The mean value of the angle between the anterior and posterior facets was found to be 140.56° ± 11.72. The mean value of the angle between the anterior surface of the tibia and the intertubercular line was 75.5° ± 5.47. No statistically significant differences were detected between the right and left sides for all measurements. It is considered that knowing the morphometric and anatomical characteristics of the fibular notch in detail will help radiologists evaluate the talocrural region. It is also considered that these data will guide surgeons and help determine the appropriate size for ankle reconstruction operations.

Three-Dimensional (3D) Analysis of Orbital Morphometry in Healthy Anatolian Adults: Sex, Side Discrepancies, and Clinical Relevance.

Background and objective The complex structural integrity of the orbit is crucial for visual functions. Three-dimensional (3D) reconstructions from radiological images have revolutionized anatomical understanding, eliminating the limitations of two-dimensional (2D) imaging and offering intricate spatial details for complex structures. The aim of this study was to analyze the detailed morphometry of the orbit in healthy Anatolian adults, considering sex, side discrepancies, and clinical relevance using 3D models reconstructed from multidetector computed tomography (MDCT) images. Materials and methods Fifty-six (44.44%) males and 70 (55.56%) females (total: 126, mean age: 48.62) MDCT images were randomly selected and 3D skull models were reconstructed using 3D Slicer software. Measurements were conducted in millimeters (mm) for transverse and vertical diameters, circumference of the orbital opening, orbital wall lengths, as well as intraorbital and extraorbital distances. Results The method of measurements showed high reproducibility of results. The mean values for transverse and vertical diameters, circumference of the orbital opening, medial and lateral wall lengths, roof and floor lengths, and intraorbital and extraorbital distances were 40.23±2.12 mm (p<0.001), 34.94±2.16 mm (p=0.365), 44.74 ±3.02 mm (p<0.001), 46.30±2.69 mm (p<0.001), 51.26±2.91 mm (p<0.001), 49.01±3.22 mm (p<0.001), 126.10±5.71 mm (p<0.001), 19.63±2.35 mm (p=0.026), and 94.09±4.84 mm (p<0.001), respectively. Conclusion The study's high measurement reproducibility contributes significantly to the existing literature and clinical practice. These findings offer specific insights into Anatolian orbital morphometry, aiding in surgical planning, implant placement, and diagnostic assessments. The precise measurement values serve as a reliable reference for clinicians, facilitating the identification of normal and abnormal orbital anatomy and enhancing patient care. We believe this study provides valuable data for craniofacial and ophthalmological research, benefiting both clinical practice and future research endeavors in these fields.

Unilateral Absence of the Latissimus Dorsi: A Report of a Rare Case.

The latissimus dorsi is the largest muscle in the human body, located in the lower posterior thorax, and it contributes to motion in the upper extremity and provides assistance in respiration. This case report describes a rare occurrence of a unilateral absence of the latissimus dorsi accompanied by contralateral scoliosis in a 73-year-old female cadaver. The absence of the muscle along with the absence of the thoracodorsal nerve and branches of the subscapular and axillary arteries was identified during a standard dissection course. The implications of this rare case extend to an array of surgical interventions, including head, neck, breast, and torso reconstructive applications. It is important to investigate potential anomalies of the latissimus dorsi, while planning or performing free flap transfers. The report also highlights the importance of understanding this variation for educational and research purposes.

Morphologic and morphometric evaluation of the wormian bones / Evaluación morfológica y morfométrica de los huesos wormianos

Wormian (sutural) bones are accessory small bones located on the skull. These bones consist of extra ossification centers around cranial sutures. This study was carried out in 28 dry human skulls with unknown age and sex in the Department of Anatomy, Cukurova University. The aim of the study was to investigate incidence and to determine morphologic and morphometric characteristics of wormian (sutural) bones. Total incidence of wormian bone presence was 42.86 % (n=12) and most of them were located on lambdoid suture (57.14 %). Wormian bones were seen at lambdoid suture at a rate of 62.5 %, occipito-mastoid suture 9.37 %, asterion 18.76 %, lambda 9.37 %, and were not seen on pterion, bregma, parietotemporal, sagittal and coronal sutures. Wormian bones were seen on left side at a rate of 65.62 % and 34.38 % on right side of skull. According to our study, wormian bone shapes were seen as quadrangular (56.26 %), triangular (15.62 %) and irregular (28.12 %). The mean values of wormian bones were as follows; vertical diameter: 12.29±4.48 mm and horizontal diameter: 10.93±4.39 mm. For cephalic index, the result of our study shows that most of our skulls with or without wormian bones belong to dolichocephalic group. Knowledge of variations and characteristics of skull is important for forensic medicine, anatomy, radiology and neurosurgery fields and for literature data or clinical practices.

Los huesos wormianos o huesos suturales, son pequeños huesos accesorios ubicados en el cráneo. Estos huesos consisten en centros de osificación adicionales alrededor de las suturas craneales. Este estudio se realizó en 28 cráneos humanos secos con edad y sexo desconocidos en el Departamento de Anatomía de la Universidad de Cukurova. El objetivo del estudio fue investigar la incidencia y determinar las características morfológicas y morfométricas de los huesos wormianos. La incidencia total de presencia de hueso wormiano fue del 42,86 % (n = 12) y la mayoría de estos se localizó en sutura lambdoidea (57,14 %). Los huesos wormianos se observaron en la sutura lambdoidea a una tasa del 62,5 %, sutura occipito-mastoidea 9,37 %, asterion 18,76 %, lambda 9,37 %, y no se observaron en suturas pterion, bregma, parietotemporal, sagital y coronal. Los huesos wormianos se observaron en el lado izquierdo a una tasa del 65,62 % y del 34,38 % en el lado derecho del cráneo. Según nuestro estudio, las formas óseas se consideraron cuadrangulares (56,26 %), triangulares (15,62 %) e irregulares (28,12 %). Los valores medios de los huesos wormianos fueron los siguientes; diámetro vertical: 12,29 ± 4,48 mm y diámetro horizontal: 10,93 ± 4,39 mm. Referente al índice cefálico, el resultado de nuestro estudio muestra que la mayoría los cráneos con o sin huesos wormianos pertenecen al grupo dolicocefálico. El conocimiento de las variaciones y características del cráneo es importante para la medicina forense, la anatomía, la radiología y los campos de neurocirugía, como asimismo para los datos de la literatura o las prácticas clínicas.
