The plantaris muscle is characterised by morphological variability, both for origin and insertion, and may sometimes be absent. Its strength allows the ligament to be used for reconstruction of other tendons and ligaments. This report presents the rare placements and course of the plantaris muscle in relation to the neurovascular bundle. In this case, the hypertrophy of this muscle might cause pressure on the tibial nerve and produce symptoms similar to sciatica. (Folia Morphol 2018; 77, 4: 785–788)
The concept of the study was to find the correlation between the morphometry of the suprascapular notch and basic anthropometric measurements of the human scapula. The measurements of the human scapulae included: morphological length and width, maximal width and length projection of scapular spine, length of acromion, and maximal length of the coracoid process. The glenoid cavity was measured in two perpendicular directions to evaluate its width and length. The width-length scapular and glenoid cavity indexes were calculated for every bone. In addition to standard anthropometric measurements two other measurements were defined and evaluated for every suprascapular notch: maximal depth (MD) and superior transverse diameter (STD). The superior transverse suprascapular ligament was completely ossified in 7% of cases. Ten (11.6%) scapulae had a discrete notch. In the studied material, in 21 (24.4%) scapulae the MD was longer than the STD. Two (2.3%) scapulae had equal maximal depth and superior transverse diameter. In 47 (57.7%) scapulae the superior transverse diameter was longer than the maximal depth. There was no statistically significant difference between anthropometric measurements in the group with higher MD and the group with higher STD. The maximal depth of the suprascapular notch negatively correlated with the scapular width-length index. The maximal depth of the scapular notch correlated with the morphological length of the scapulae. (Folia Morphol 2011; 70, 2: 109–115)
Background: The aim of the study was to determine the localisation of the infraorbital foramen in relation to chosen anthropometric landmarks as novel reference points: nasion, rhinion, and frontomalare orbitale, and to verify their symmetry. Material and methods: Sixty-four sides of thirty-two human skulls were investigated. The distances between the infraorbital foramina and nasion, rhinion, and frontomalare orbitale, and the distances between two contralateral infraorbital foramens were measured. The symmetry was analysed and statistical analysis was performed. Results: The mean distance and standard deviation (mean ± SD) between the right infraorbital foramen and the nasion, rhinion, and right frontomalare orbitale were 45.23 ± 3.20 mm, 39.84 ± 1.72 mm, and 36.28 ± 1.50 mm, respectively, and between the left infraorbital foramen and the nasion, rhinion, and left frontomalare orbitale were 44.38 ± 2.76 mm, 38.88 ± 2.01 mm, and 36.31 ± 2.19 mm, respectively. Conclusions: The results presented in this study may be particularly helpful for surgery in patients with oedema of the infraorbital region when the other landmarks are difficult to localise.

The aim of this research was to investigate if perennial, professional weightlifting training, started at puberty, leads to hypertrophy of the patellar ligament (PL). The knee examinations were performed with a 1.5 T magnetic resonance imaging system. The area of the cross-sectional area (CSA) of the PL midsubstance was evaluated in T1-weighted images. A control group of 19 participants was also examined with the same protocol. A significant increase of the PL midregion CSA was observed in a group of weightlifters. The area of the PL midsubstance and the onset of training were very strongly, reversely correlated. This paper presents the first description of PL midregion hypertrophy due to professional weightlifting training initialised and continued from a pubertal spurt. The described overgrowth is more intensified than has been reported for other parts of the PL. Moreover, it has been observed in the region that is the least susceptible for injuries, which in another situation could also have led to increased volume of the PL. The described phenomenon should be considered by orthopaedic surgeons because it can influence the choice of the surgical technique for cruciate ligament reconstruction as the PL is one of the structures for harvesting autografts.
