Abstract Background A detailed understanding of scaphoid anatomy helps anatomic fracture reduction, and optimal screw position. Therefore, we analysed (1) the size and shape variations of the cartilage and osseous surface, (2) the distribution of volumetric bone mineral density (vBMD) and (3) if the vBMD values differ between a peripheral and a central screw pathway? Methods Forty-three fresh frozen hand specimens (17 females, 26 males) were analysed with high-resolution peripheral quantitative computed tomography (HR-pQCT) and dissected to compute a 3D-statistical osseous and cartilage surface model and a 3D-averaged vBMD model of the scaphoid. 3D patterns were analysed using principal component analysis (PCA). vBMD was analysed via averaging HR-pQCT grey values and virtual bone probing along a central and peripheral pathway. Results (1) PCA displayed most notable variation in length ranging from 1.7 cm (− 2SD) to 2.6 cm (mean) and 3.7 cm (+ 2SD) associated with differences of the width and configuration of the dorsal surface (curved and narrow (4 mm) to a wider width (9 mm)). (2) High vBMD was located in the peripheral zone. Lowest vBMD was observed in the centre and waist. (3) Virtual probing along a peripheral pathway near to the cartilage surfaces for the capitate and lunate allowed the center region to be bypassed, resulting in increased vBMD compared to a central pathway. Conclusion High anatomical variations regarding the osseous and cartilage surfaces were associated with three distinct concentrically arranged zones with notable different vBMD. The complex scaphoid anatomy with its waist might alter the strategy of fracture fixation, education and research.

Antecedentes: La conciencia y el conocimiento de las variaciones anatómicas de las fisuras del pulmón es requerido por los discípulos de especialidades interesados para una interpretación precisa sobre diferentes técnicas de imagen. Este conocimiento es necesario para el reconocimiento de la anatomía lobular y así localizar los segmentos broncopulmonar. Por lo tanto, se realizó un estudio cadavérico que informa la prevalencia de variaciones de número de fisuras del pulmón en población Punjabi. Método: Las cavidades torácicas de 50 cadáveres debidamente embalsamados que contienen los pulmones fueron disecados y se observaron las características morfológicas de las variaciones anatómicas como número, fisuras y los lóbulos. Resultados: Cien fisuras pulmonares se observaron en 55 pulmones. Había variaciones en 41 pulmones derecho y 14 pulmones izquierdos. Cinco pulmones derechos mostraron ausencia de fisura horizontal, un pulmón derecho no tenía fisura, quince pulmones derechos mostraron fisura horizontal incompleta. Once pulmones derechos y seis pulmones izquierdos tuvieron fisuras oblicuas incompletas. En cuatro pulmones izquierdos la fisura oblicua estuvo ausente. Se observaron fisuras supernumerarias en cuatro pulmones izquierdos y nueve pulmones derechos. Las conclusiones: El conocimiento anatómico de las variaciones de fisuras y lóbulos puede ser importante, y también para académicos en el campo médico. Las conclusiones con respecto a las variaciones vistas en fisuras de ambos los pulmones fueron comparables con estudios anteriores. Las variaciones de anatomía pulmonar son importantes para ambos: el diagnóstico por radiólogos que interpretan radiografías y escáneres de tomografía computada y el tratamiento de varias enfermedades pulmones por cirujanos al realizar lobectomías y por clínicos que implican todos los dominios de la medicina. Background: Awareness and knowledge of anatomical variations of fissures of lung is required by the disciples of concerned specialties for accurate interpretation on different imaging techniques. This knowledge is necessary for the appreciation of lobar anatomy and thus locating the bronchopulmonary segments. Therefore a cadaveric study was undertaken to report the prevalence of variations involving number of fissures of lung in Punjabi population. Methods: The thoracic cavities of 50 properly embalmed cadavers containing lungs were dissected and morphological features like number, fissures and lobes were observed for the presence of anatomical variations. Results: A total of 100 variant pulmonary fissures appeared in 55 lungs. There were variations in 41 right lungs and 14 left lungs. Five right lungs showed the absence of horizontal fissure, one right lung was without any fissure, fifteen right lungs showed incomplete horizontal fissure. Eleven right lungs and six left lungs had incomplete oblique fissures. In four left lungs oblique fissure was absent. Supernumerary fissure was seen in four left lungs and nine right lungs. Conclusions: Anatomical knowledge of variations of fissures and lobes may be important, and also to academicians in the medical field. The findings regarding the variations seen in fissures of both the lungs were comparable with previous studies. Variations of lung anatomy are important for both the diagnosis by radiologists interpreting X-rays and CT scans and treatment of various lungs diseases by surgeons performing lobectomies and by clinicians involving all the domains of medicine.
