Morphometric anatomic study and clinical significance of lunate fossa [Lunat fossanin morfometrik anatomik çalişmasi ve klinik önemi]

Objectives: this study aims to investigate the depth,transverse and sagittal diameters of lunate fossa which is a significant structure of the wrist in terms of reducing the risk for volar plate screws,which are administered in distal radius fractures,from penetrating into the joint. materials and methods: depth,transverse and sagittal diameters of lunate fossa in 50 right and 50 left adult dried radius bones without distal tip damage were measured by using microscribeg2x from the microscribe g series. results: mean lunate fossa depth: left 2.419886±0.51 mm/right 2.543052±0.78 mm,mean lunate fossa sagittal diameter: left 19.656±1.57 mm/right 18.796±1.53 mm,mean lunate fossa transverse diameter: left 11.382±0.65 mm/right 11.106±0.91 mm. there was no statistically significant difference between right and left depth values of lunate fossa (p=0.320),whereas there was statistically significant difference between right and left transverse and sagittal diameters (p=0.006,p=0.048). conclusion: measurements involving depth of lunate fossa may guide the development of new anatomic plates and decrease complications like the penetration of screw into joint whilst volar plate administrations.
