Functional Outcome With Scaphotrapeziotrapezoid Arthrodesis in the Treatment of Kienböckʼs Disease Stage III

Lunate Resection and Vascularized Os Pisiform Transfer in Kienböck’s Disease: An Average of 10 Years of Follow-Up Study After Saffar’s Procedure

“…4) was not always possible and patients who experienced osteoarthritis had a tendency toward an increased preoperative RSA. We must state, however, that even for STT arthrodesis the correction of malrotated scaphoid and decreased carpal index is not always possible within normal values as described by Sauerbier et al, 11 Minami et al, 15 and Prommersberger et al 16 In general a partial intercarpal arthrodesis such as STT or scaphocapitate arthrodesis frequently is performed in late-stage Kienböck's disease. For those salvage procedures a DASH score of 19 to 31 points can be expected and the ROM is reduced to 52% to 63% whereas the grip power is 64% to 71% of the opposite side.…”

“…10 -16 After partial arthrodesis the Cooney score lies within 62 to 83 points and the Krimmer score is rated at 62 to 69 points. [11][12][13][14]27 Saffar's procedure seems comparable with the outcome of partial fusion in the later course of Kienböck's disease with an average DASH score of 23.3 points, average Cooney score of 75.4 points, average Krimmer score of 77.1 points, and average wrist ROM of 70% and average grip power of 80% of the opposite hand. In conformity with our results Brüser et al 28 described a reliable pain control by Saffar's procedure but functional outcome was lower in that study than in ours.…”

Vascularized Os Pisiform for Reinforcement of the Lunate in Kienböck’s Disease: An Average of 12 Years of Follow-Up Study

“…3,[35][36][37] Decompression by partial arthrodesis in the early stages of Kienböck's disease, however, is performed at the cost of ROM, resulting in limited subjective and clinical results. [3][4][5][6][7][8][9] Nevertheless in advanced stages those salvage procedures are an option because they can prevent or to some extent even correct carpal collapse. For intercarpal arthrodesis the DASH score was 19 to 31 points and ROM was reduced to 52% to 63% and grip power to 64% to 71% of the opposite side.…”

“…Salvage procedures such as scaphotrapeziotrapezoid or scaphocapitate arthrodesis are effective at the cost of motion as is carpectomy, a procedure for advanced stages. [2][3][4][5][6][7][8][9][10] Among reconstructive treatments, leveling procedures such as radial shortening are accepted widely for ulnar-minus variance in patients with stage II to IIIa disease because these procedures decompress the lunate. 1,11,12 In neutral or even ulnar-plus variance, however, this attempt might lead to ulnar impaction.…”
