ABSTRACT

Objective By X-ray measurement of metacarpal and phalange bones in the right hand of adult patients with Kaschin-Beck disease in Qinghai Province,to provide anatomic data and information for clinic diagnosis of the disease and application of hand surgery.Methods Fifty-four cases of adult patients with Kaschin-Beck disease,who came from Guide County and Xinghai County in Hainan Prefecture,Qinghai Province,were selected as investigation subjects,then their right hand X-ray film were taken,metacarpal and phalange bones were measured by electronic digital vernier caliper.All data were analyzed with SPSS 19.0.Results The axis length of the metacarpal bones was in the order ofthe 2nd metacarpal ＞ 3rd metacarpal ＞ 4th metacarpal ＞ 5th metacarpal ＞ first metacarpal.The axis length of proximal phalange bones was in the order ofthe middle finger proximal ＞ ring finger proximal ＞ index finger proximal ＞ little finger proximal ＞ proximal thumb,while the middle,distal phalanx axis length varied greatly.The length of metacarpal and phalange bones of all male was longer than that of female(all P ＜ 0.01).The width of the metacarpal bones was in the order ofthe 2nd metacarpal ＞ 3rd metacarpal ＞ 5th metacarpal ＞ 4th metacarpal.The width of the 2nd-5th metacarpal of male and female was (8.57 ± 0.90),(8.25 ± 0.80),(6.84 ± 0.69),(7.70 ± 0.77)mm and (7.40 ± 0.74),(7.36 ± 0.70),(6.00 ± 0.57),(6.62 ± 0.65)mm,respectively,the differences were significant(t =5.24,4.32,4.85,5.55,all P ＜ 0.01).The matacarpal bone index of female[(8.23 ± 0.90)mm] was significantly larger than that of male[(7.61 ± 0.76)mm,t =2.73,P ＜ 0.01].Conclusion X-ray measurement of hand may provide reference information for diagnosis of Kaschin-Beck disease and determination of metacarpal and phalange length in hand surgery.
