Eleven horses with acute or chronic incomplete cortical fractures of the left or right third metacarpal bone (McIII) were treated with surgical puncture (osteostixis). The fractures were diagnosed by physical examination and radiography. Four to eight holes, 2.7 or 3.5 mm in diameter, were drilled in the fractured bone. Radiographically, the fractures were healed by month 3, and the drill holes were inapparent by month 7. Nine horses (82%) returned to race competition, and two horses were retired, one the result of a surgical complication. The mean time between surgery and the first race was 9.4 months. None of the bones refractured within 24 months of surgery. Osteostixis was not technically difficult and a second operation for implant removal was not necessary.
11匹左右第三掌骨（McIII）发生急性或慢性不完全皮质骨折的马接受了手术穿刺（骨穿刺术）治疗。通过体格检查和X线摄影诊断骨折。在骨折骨上钻4至8个直径为2.7或3.5毫米的孔。X线显示，骨折在第3个月愈合，钻孔在第7个月时不明显。9匹马（82%）恢复了比赛，2匹马退役，其中1匹是手术并发症导致的。手术至首次比赛的平均时间为9.4个月。术后24个月内，所有骨头均未再次骨折。骨穿刺术技术上并不困难，无需进行二次手术取出植入物。
