Twenty-six patients with scaphoid nonunion were reexamined 22 to 39 years after Bentzon's soft tissue interposition arthroplasty was performed. All but one were satisfied, although three still had moderate pain. Mobility of the wrist was reduced by 20% to 25% and grip strength by 8%. The nonunion remained open and unstable in 16 of 25 radiologically reexamined cases. Carpal collapse, which had increased over time, was found in 15 cases, nine of which presented an unstable nonunion. Osteoarthritis had developed in five of 15 wrists with carpal collapse and in two of 10 without it. No significant osteoarthritis was found in any case earlier than 27 years after the operation. Thus, the risk of disability that is due to late degenerative changes of the wrist is small, even in the presence of carpal collapse.
对26例舟骨不愈合患者在接受本特松软组织植入关节成形术后22至39年进行了复查。除1例患者外，其他患者均表示满意，不过仍有3例患者存在中度疼痛。腕关节活动度降低了20%至25%，握力降低了8%。在25例接受放射学复查的病例中，有16例不愈合仍未愈合且不稳定。随着时间推移，15例出现腕骨塌陷，其中9例为不稳定不愈合。15例腕骨塌陷患者中有5例出现了骨关节炎，10例未出现腕骨塌陷的患者中有2例出现了骨关节炎。术后27年之前，任何病例均未发现明显的骨关节炎。因此，即使存在腕骨塌陷，因腕关节晚期退行性变导致残疾的风险也很小。
