首先，由于指关节内骨软骨瘤与受累指骨的关节软骨一起持续生长，所以它们可以引起畸形或者活动受限。

First, because intraarticular osteochondromas of the finger grow in continuity with the articular cartilage of the affected phalanx, they can cause deformity or limitation of motion.

相反地，在关节内指骨骨软骨瘤的患者疼痛是相对少见的症状，与传统的骨软骨瘤患者类似。

Conversely, pain is a relatively rare symptom in patients with intra-articular phalangeal osteochondromas, just as is the case in those with conventional osteochondroma.

畸形可能是由骨软骨瘤过度生长或关节软骨增生引起，而且有时可继发于活动受限。

Deformities may be caused by overgrowth of an osteochondroma or hyperplasia of articular cartilage and sometimes can occur secondary to changes induced by limitation of motion.
