方法观测成套肋骨标本，描述肋头关节形态学特征。
Methods Complete costal specimens were observed and morphological characteristics of joints of costal head were described.
结论肋头关节面多分为单、双两种形态，其中第3～10肋双关节面出现率更高，且形态变异较大，可能是双关节面更易出现肋头关节劳损与错位的重要原因。
Conclusion The articular surface of costal head is divided into single form and double form. Double form is prone to appear in 3 to 10 costal ribs with more morphological variations;
