Comments about “The hamate facet of the lunate: a radiographic study in an Arab population from Bahrain”

Excerpt

In the interesting paper [1] authors show that “the incidence of type II lunate in 38.8% of the Arab subjects from Bahrain was much lower than that reported in the literature of populations from the Western world”. The results of our previous study on the 100 macerated lunate bones of the Bulgarian subjects from Southeastern Europe show that the incidence of type II lunates is 66% [2, 3]. These results support the Dharap’s conclusion [1] that “the incidence of type II lunates seems to vary in different populations”. According to Dharap [1] the lower incidence of type II lunate bone in the Arab population in Bahrain could be attributed to a genetic variation. However, literature data cited by the authors in the Table 1 has been obtained by means of different methods of examination: cadaver dissection, plain radiographs, MR images and arthroscopy. In our previous study we have drawn attention to the fact that the identification of type II lunate incidence with cadaver dissection is more precise than the identification by means of plain radiographs [2, 3]. …
