This study was designed to find a possible correlation between the presence of the palmaris longus and function of the fifth flexor digitorum superficialis. We examined 300 participants to assess the absence of palmaris longus and flexor digitorum superficialis function by several clinical tests. Overall absence of palmaris longus, was seen in 157 participants (52.3%). ⋯ Bilaterally presence of these muscles we noted in 95 participants (31.7%). We believe that there is no connection between absent palmaris longus and absent function of flexor digitorum superficialis. We found a much higher prevalence of muscles absence individually and jointly than in other studies.

The aim of this study was to identify the fragment's shape by evaluating olecranon fractures. We examined the CT images of 48 olecranon fractures (28 women and 20 men). Mean age was 59.9 years. ⋯ The mean tip radial edge was 1.96 mm, and the flat spot width was 12.64 mm ; therefore, the tip radial ratio was 0.15 mm. Radial inclination on the articular surface was 30.55°. Our findings confirmed our hypothesis that the fracture lines run from the proximal ulnar side to the distal radial side on the olecranon's posterior and articular surfaces.
