Surgical outcome of radial osteotomy for Kienböck’s disease—minimum 10 years of follow-up

Lunate Revascularization After Capitate Shortening Osteotomy in Kienböck's Disease

“…8 Figure 1 (case 3) demonstrates decreased signal intensity of the lunate on preoperative T1-weighted MRI. Figure 2 (case 3), which indicates revascularization, demonstrates increased signal intensity of the lunate on MRI fat suppression image 3 months after surgery.…”

“…Within the lunate, improvement of sclerosis, cystic changes, and fragmentation indicate revascularization of the bone. 7,8 Radiography is ineffective in detecting the revascularization process early.…”

“…3,7,8 Nakamura et al observed 24 patients with Kienböck's disease for 1 to 3 years with serial magnetic resonance imaging (MRI). Nineteen patients who had radial shortening or radial wedge osteotomies demonstrated an increase in signal intensity on T1-or T2-weighted images.…”

Kienböck's Disease

“…28 Koh et al reported improvements in pain, motion, and function at a minimum 10-year follow-up. 29 However, arthritic changes were seen in almost three quarters of the patients at the latest follow-up, suggesting that disease progression was not halted. The goal of these procedures is to unload the articular surfaces of the lunate by shifting the load to adjacent carpal articulations.…”

Morbus Kienböck

“…Die ungeheuerliche Vielfalt an seither veröffentlichten Behandlungsoptionen lässt unschwer erahnen, dass es derzeit noch keine eindeutig zuverlässige und überlegene Therapieoption gibt [7,8,9,10,11,12,13,14,15,16,17]. Dies ist unter anderem dadurch begründet, dass bisher weder die Ätiologie noch die Pathogenese dieser Erkrankung klar definiert werden konnten [18,19,20,21,22,23,24,25].…”
