Forty-five patients with persistent ulnar-sided wrist pain and a positive ulnocarpal stress test were investigated by X-ray, arthrography, 99mTechnetium bone scanning, magnetic resonance imaging and wrist arthroscopy. Ulnar wrist pathology was positively identified in nine of 45 patients by X-ray, 18 of 37 by arthrography, 19 of 27 by bone scan, four of 33 by MRI, and in all 45 patients by arthroscopy. The final diagnosis was ulnocarpal abutment syndrome in 28 patients, traumatic triangular fibrocartilage (TFC) tear in six, lunotriquetral (LT) ligament tear in five, TFC and LT ligament tear in one, wrist arthritis in four and cartilaginous free body in one. The ulnocarpal stress test is a useful provocative test, and a positive test suggests the presence of ulnar-sided wrist pathology. The test is sufficiently sensitive to warrant further investigation by arthroscopy.
对45例持续性尺侧腕部疼痛且尺腕关节应力试验阳性的患者进行了X线、关节造影、99m锝骨扫描、磁共振成像和腕关节镜检查。45例患者中，X线检查阳性发现尺腕部病变9例，关节造影37例中18例阳性，骨扫描27例中19例阳性，MRI检查33例中4例阳性，腕关节镜检查45例均为阳性。最终诊断为尺腕撞击综合征28例，创伤性三角纤维软骨（TFC）撕裂6例，月三角（LT）韧带撕裂5例，TFC和LT韧带撕裂1例，腕关节炎4例，软骨游离体1例。尺腕关节应力试验是一种有用的激发试验，阳性试验提示存在尺侧腕部病变。该试验灵敏度足够高，值得进一步行腕关节镜检查。
