Volar subluxation of the tendons of the first dorsal compartment of the wrist occurred in two patients after surgery for treatment of de Quervain's stenosing tenosynovitis. In both patients a painful tenosynovitis of the extensor pollicis brevis and abductor pollicis longus developed, which was unresponsive to conservative therapy as the tendons prolapsed over the prominence of the first dorsal compartment. A distally based flap of the brachioradialis tendon was used to prevent tendon prolapse, with both patients asymptomatic and free of subluxation one and five years after operation.
两名患者在接受治疗桡骨茎突狭窄性腱鞘炎的手术后，出现了腕部第一背侧腱鞘肌腱掌侧半脱位。两名患者均出现拇短伸肌和拇长展肌疼痛性腱鞘炎，由于肌腱在第一背侧腱鞘突出处脱垂，保守治疗无效。采用以远端为蒂的桡侧腕长伸肌腱瓣预防肌腱脱垂，两名患者术后1年和5年均无症状且无半脱位。
