Colles fractures are usually treated with closed reduction and forearm plaster. Even if reduced perfectly, some of these fractures tend to redislocate dorsally and radially, requiring repeated reduction maneuvers. Since K-wires cannot be firmly anchored in the distal fragment if comminution exists, Kapandji proposed a method whereby the distal fragment is not pinned at all. He introduced the pins through the fracture itself and into the medullary canal of the proximal fragment, anchoring the wires into the opposite cortices of the radius shaft. In order to "pre-stress" the K-wires, Böhler and Zifko modified the technique and the wires themselves. They inserted the wires through small skin incisions into the fracture and into the proximal fragment as medullary pins. The specially bent pins glide smoothly into the medullary cavity and snugly fit along the distal fragment; thereby minimizing the chance of damaging extensor tendons. One pin is inserted proximal to Lister's tubercle and another radially, proximal to the radial styloid. Technique, indication, and possible technical errors are discussed based on the follow-up of forty one patients.
科雷氏骨折通常采用闭合复位和前臂石膏固定治疗。即使复位完美，其中一些骨折仍倾向于向背侧和桡侧再脱位，需要反复进行复位操作。由于存在粉碎性骨折时克氏针无法牢固固定在远端骨折块上，卡潘迪提出了一种根本不固定远端骨折块的方法。他将针穿过骨折本身并插入近端骨折块的髓腔，将钢丝锚固在桡骨干的相对皮质上。为了对克氏针进行“预加应力”，伯勒尔和齐夫科改进了技术及克氏针本身。他们通过小切口将针插入骨折处并作为髓内针插入近端骨折块。特殊弯曲的针能顺利滑入髓腔并紧密贴合远端骨折块；从而将损伤伸肌腱的几率降至最低。一根针插入利斯特结节近端，另一根针在桡骨茎突近端桡侧插入。基于对41例患者的随访，讨论了该技术、适应症及可能的技术失误。
