Radioscapholunate arthrodesis versus radiolunate arthrodesis in rheumatoid wrist surgery: Clinical and radiographic outcomes

Single- and Bicolumn Limited Intercarpal Fusion: A Solution for the SLAC or SNAC Wrist

Background  Single- or bicolumn limited intercarpal fusion, also called one- or two-column fusion, has been introduced as an alternative to four-corner fusion. The rationale behind this is obtaining less need for bone grafting and consequently improving the chances of the union. Method  From August 2014 to October 2020, 45 consecutive patients (15 women), with a mean age of 58.4 years (range: 35-79), have been treated for scapholunate advanced collapse or scaphoid nonunion advanced collapse wrist. In 33 cases, the surgery was performed as two-column fusion, and in 12 cases as one-column fusion. The union was determined by a computed tomography (CT) scan or X-ray follow-up studies. The pain assessments (visual analog score: 0-100), range of motion (ROM), grip strength, and Quick Disabilities of the Arm, Shoulder, and Hand score were prospectively included. Results  Of 45 patients, 43 were available for the follow-up, at a mean of 35 months (range: 12-68). All patients but two achieved union at a mean of 9.5 weeks (range: 5-25 weeks). Pain diminished from 60.3 (mean) preoperatively to 16.7 (mean) postoperatively ( p  = 0.0001). Grip strength slightly increased from 28.2 KgF (mean) to 29 KgF (mean) (not significantly, p  = 0.86). Quick Disability of the Arm, Shoulder, and Hand score improved from 39.5 (median) before the surgery to 11 (median) after the surgery ( p  = 0.0004). The postoperative ROM of 62/37 degrees (mean) were recorded for total dorsovolar/radioulnar flexions, respectively. Three patients were converted to total wrist fusion and one to total wrist arthroplasty. One had a rearthrodesis to two-column fusion, which united. Conclusion  One- and two-column fusion showed significant improvement in pain and function, with minimal impairment of the grip strength on the short- to mid-term follow-up. A union rate of 95% and an acceptable complication rate were achieved, without fusing all carpals. Level of Evidence  Prospective, cohort study, level III.

Radiolunate arthrodesis and scaphoidectomy combined to Sauvé-Kapandji procedure as treatment of wrist osteoarthritis: Clinical and radiological results

OBJECTIVE

The aim of this study was to analyze clinical and radiological results for 1-stage radiolunate arthrodesis and scaphoidectomy associated to the Sauvé-Kapandji procedure, to alleviate pain and conserve wrist motion.

METHODS

Seven patients (8 wrists) with symptomatic osteoarthritis of the radiolunate and distal radioulnar joints were treated from 1999 to 2016. Mean age at surgery was 49 years and M/F sex ratio was 6/1. Etiologies were distal radial intra-articular malunion for 6 patients and bilateral gouty arthritis for 1. The procedure was performed by a dorsal approach in a single step. Pain was assessed on visual analogue scale (VAS). Pre- and post-operative active flexion-extension and pronation-supination were compared. The secondary endpoint was onset of postoperative complications.

RESULTS

At a mean 71 months' follow-up (range, 30-168 months), there was significant reduction in pain (VAS, 0.5/10; p < 0.0001). Motion results were satisfactory, with 32° flexion, 39° extension, for a non-significant decrease of 11° and 5° respectively; pronation and supination were significantly increased, by a mean 23° and 30° respectively. Three wrists (37.5%) required a second surgery. There were no cases of surgical site infection or non-union.

CONCLUSION

Radiolunate arthrodesis and scaphoidectomy combined to Sauvé-Kapandji procedure was an effective solution for the treatment of symptomatic radiolunate and distal radioulnar osteoarthritis.
