“…Isolated STT arthritis can also exist and it has been reported in 15% of wrist radiographs and 21% of cadaveric wrists. (Watson and Ballet 1984;Viegas, Patterson et al 1993). Higher incidence rates have also been published and it is believed that the age of the cadavers may explain the differences in values.…”

“…A Type I lunate has one distal facet for articulation with the capitate while a Type II lunate has an additional facet medially for articulating with the hamate (Viegas et al, 1990;Nakamura et al, 2001;Dharap et al, 2006a). The prevalence of the Type II lunate ranges from 26.7 % to 73.3 % and shows population variation (Viegas et al, 1993, Dharap et al, 2006a.…”

“…Type II lunate is more prone to degenerative changes in the hamato-lunate joint (HLJ) that may cause ulnar-sided wrist pain (Burgess, 1990;Viegas et al, 1993;Nakamura et al, 2000;Galley et al, 2007;Haase et al, 2007). In Type II lunates the width of the accessory facet ranges from 1-12 mm (Viegas et al, 1993;Lamas et al, 2007).…”

SUMMARY:The morphology and morphometry of the distal articular surface of the lunate exhibits inter-population variations. They are of clinical importance to hand surgeons due to their influence on the occurrence of proximal pole arthrosis which is a cause of ulnar-side wrist pain. The objective of the study was to determine the morphology and morphometry of the distal articular surface of the lunate bone in an adult Kenyan population. A descriptive cross-sectional study at the Department of Human Anatomy, University of Nairobi. Fifty-six human hands obtained for routine dissection were used. The morphology of the distal articular surface of the lunate was classified as either Type I or Type II depending on the absence or presence of a medial facet for articulation with the hamate respectively. The width of the wrists and of the medial facet in Type II lunates was measured with SOMETTM CN-25 1234 vernier calipers (accurate to 1mm). Photomacrographs of representative lunate were taken. Data were analyzed using SPSS version 17.0. The Pearson correlation test was used to check for any correlations. Type II lunate morphology was more common with a prevalence of 34 (61 %) while 19 (34 %) were Type I. The mean width of wrists with Type I lunate was 41.1±2.8 mm while those with Type II had a mean width of 46.1±4.3 mm. The mean width of the medial facet in lunate type II was 4.4±1.4 mm. Lunotriquetral fusion was demonstrated in 3 (5 %) wrists. Prevalence of Type II lunate was higher than Type I. Wrists with a Type II lunate were wider than those with Type I. There was no correlation between the width of the wrist and the width of the medial facet of the lunate.

purpose. To compare 5 different Kirschner wire fixation techniques in terms of the failure loads seen as scapholunate (SL) dissociation in a cadaveric, biomechanical study. Methods. 10 fresh-frozen, finger-amputated wrists with sectioned SL ligaments from 3 male and 2 female cadavers were tested. The change of SL angle, SL dissociation, and the load to failure of the 5 different Kirschner wire fixation techniques (using 1.4-mm Kirschner wires) were compared using an axial loading testing machine. The techniques were: (1) SL fixation (using one wire), (2) SL fixation (using 2 wires), (3) SL and scaphocapitate (SC) fixation, (4) SL, SC, and capitolunate (CL) fixation, and (5) CL fixation alone. results. There was no significant difference between SL fixations using one or 2 wires. The force for SL dissociation was significantly greater in the SL-SC fixation than the SL fixation using one wire (p=0.003). The SL-SC-CL fixation was not significantly stronger 2012;20(2):224-9 than the SL-SC fixation. conclusion. The SL-SC fixation achieved adequate stabilisation of both carpal rows with minimal biological impairment.
