FRACTURES OF THE METACARPAL BASE
Excepting fractures of the thumb metacarpal, these are usually stable injuries which can be treated by ensuring that rotation is correct and then splinting the digit in a volar slab extending from the forearm to the proximal finger joint. The splint is retained for 3 weeks and exercises are then encouraged.
Displaced intra-articular fractures of the base of the fourth or fifth metacarpal may cause marked incongruity of the joint. This is a mobile joint and it may, therefore, be painful. The fracture should be reduced by traction on the little finger and then held with a percutaneous K-wire or compression screw. In the long term, if painful arthritis supervenes, treatment would be with either arthrodesis or joint excision.

掌骨基底骨折
除了拇指掌骨骨折，这些通常是稳定的损伤，可以通过确保旋转正确，然后用夹板将手指固定在掌板上，从前臂延伸到近端手指关节。夹板保留3周，然后鼓励锻炼。
移位的第四或第五掌骨基底关节内骨折可引起明显的关节紊乱。这是一个活动关节，因此可能会很痛。骨折应该复位通过对小指进行牵引，然后用经皮K形钢丝或加压螺钉固定。从长远来看，如果疼痛性关节炎复发，治疗方法可以是关节融合术或关节切除术。

用克氏针利用邻近掌骨支架固定治疗第一掌骨基底部骨折脱位，第五掌骨颈骨折，损伤小，疗效好，不需二次手术，费用不高。
