Clinical significance of clavicle morphometry
Purpose: Clavicle is the bony link between upper extremity and the body. This study is undertaken to assess the anatomical structure of clavicle and to determine the morphometric measurements. Materials and Methods: Sixty-six clavicle of unknown gender of an Anatolian population (34 left-32 right) are included. Maximum claviculer length, the perimeter of the midpoint, the superior inferior and anterior posterior thickness of extremitas acromialis, the distance between the lateral border of the clavicle and the midpoint of linea trapezoidea, maximum length and width of impressio costoclavicularis, maximum length and width of fascies sternalis, maximum lengt hand width of facies acromialis and concave angle are measured in addition the Robustness index (endurance index) is calculated. Results: Maximum claviculer length was 136.19 +/- 13.41 mm; superior inferior thickness of extremitas acromialis was 10.59 +/- 2.15 mm; and anterior posterior thickness of extremitas acromialis was 21.62 +/- 3.87 mm; the distance between the lateral border of the clavicle and the midpoint of linea trapezoidea was 17.06 +/- 3.83 mm; maximum length of impressio costoclavicularis was 16.51 +/- 5.11 mm; and maximum width of impressio costoclavicularis was 8.07 +/- 2.88 mm; maximum length of fascies sternalis was 16.58 +/- 3.22 mm; and maximum width of fascies sternalis was 20.26 +/- 3.29 mm maximum length of fascies acromialis was 9.10 +/- 2.55 mm; maximum width of fascies acromialis was 14.74 +/- 3.43 mm; concave angle was 139.43 +/- 8.25 degrees; the perimeter of the midpoint of the clavicle was 3.57 +/- 0.46 mm and the Robustness index (endurance index) was calculated to be 2.63 +/- 0.32. Conclusion: Knowledge on the clavicular measurements may be essential for orthopaedic surgeons in acute displaced midshaft clavicle fractures and to choose a standart treatment modality in many other conditions.
