Since 1969, a slightly modified silicone-rubber neurosurgical burr-hole cover has been used for a type of interposition arthroplasty of the carpometacarpal joint of the thumb. The short stem of the device fits into a hole burred into the distal surface of the trapezium. The flat surface of the device covers the distal surface of the trapezium. Forty-nine operations were done on 42 patients, 35 women and seven men. The age range of the patients was 34 years to 72 years, with an average of 55 years. The average follow-up time was 31 months. Forty results were rated as excellent. There were two failures due to breakage of the device, and in both cases the breakage was due to a technical error.
自1969年以来，一种经过略微改良的硅橡胶神经外科钻孔盖被用于拇指腕掌关节的一种间置关节成形术。该装置的短柄适配于在大多角骨远端表面钻出的孔中。装置的平面覆盖大多角骨的远端表面。对42例患者进行了49次手术，其中女性35例，男性7例。患者年龄范围为34岁至72岁，平均年龄55岁。平均随访时间为31个月。40例结果评定为优秀。有2例因装置断裂而失败，且在这两例中，断裂均归因于技术失误。
