Two rare cases of bowler's thumb (traumatic neuropathy of the ulnar digital nerve of the thumb) were treated surgically with encouraging results. These had different types of lesion, involving nodular neuroma and epineural mass, which were distinguished by magnetic resonance imaging. The surgical outcome for active bowlers is unclear and postoperative protection from the repetitive trauma of throwing is important. Possible technical solutions include changing the size and weight of the ball, the spacing between holes, the fitting of thumb to ball, and the slope and size of thumb holes. It is important that both bowlers and clinicians are sufficiently aware of bowler's thumb to allow early diagnosis and treatment of this lesion.
两例罕见的保龄球拇指（拇指尺侧指神经创伤性神经病变）患者接受了手术治疗，效果令人鼓舞。这两例患者有不同类型的损伤，包括结节性神经瘤和神经外膜肿物，通过磁共振成像得以区分。对于活跃的保龄球运动员而言，手术效果尚不清楚，术后防止投掷动作的重复性创伤很重要。可能的技术解决方案包括改变球的大小和重量、孔之间的间距、拇指与球的贴合度以及拇指孔的倾斜度和大小。保龄球运动员和临床医生都应充分认识保龄球拇指，以便早期诊断和治疗这种损伤，这一点很重要。
