To our knowledge, there has been only one previous description of dislocation of the radial head associated with cerebral palsy. This paper describes nine such dislocations, eight of which were bilateral and posterior and one, unilateral and anterior. There was an incidence of this abnormality of 2.4 per cent in 368 of the cases surveyed. Of those patients with cerebral palsy and with flexion contracture of the elbow and pronation contracture of the forearm, 27 per cent had the dislocation.
据我们所知，此前仅有一篇关于与脑瘫相关的桡骨头脱位的描述。本文描述了9例此类脱位，其中8例为双侧后脱位，1例为单侧前脱位。在所调查的368例病例中，这种异常的发生率为2.4%。在患有脑瘫且伴有肘部屈曲挛缩和前臂旋前挛缩的患者中，27%发生了脱位。
