“…Previous studies have shown that the type II lunate may be protective of carpal instability in cases of scaphoid nonunions and scapholunate dissociations. 12,13 The present study noted smaller radioscaphoid angles in wrists with an intact type II lunate (mean, 45 ) compared with wrists with an intact type I (mean of 53 ) lunate. More importantly, this difference was not seen between the 2 types of lunates when a coronal plane fracture was present.…”

“…20,23,24 In cohort studies of patients with scaphoid nonunions and scapholunate dissociations, a type II lunate was present in 53% (24 of 45) and 57% (33 of 58) of wrists, respectively. 12, 13 Kato et al noted a type II lunate in 26% (6 of 23) of the unaffected (contralateral) wrist in patients with radiographic findings consistent with Kienböck disease. 14 The present study reports a 29% prevalence of a type II lunate in the affected wrist in patients with Kienböck disease.…”

“…10,11 A type II lunate has been previously evaluated and shown to be protective against dorsal intercalated segment instability (DISI) deformities for scaphoid nonunion and scapholunate dissociation. 12,13 A few studies have evaluated the radiographic characteristics of the carpus in patients with Kienböck disease. 6,14 The purpose of this study was to determine the effect of lunate morphology on the radiographic characteristics and severity of Kienböck disease upon initial presentation.…”

“…The presence of a medial distal facet in type II lunate is associated with different movement patterns and ligamentous attachment in the wrist (Galley et al). More important, it is associated with cartilage erosion and arthrosis at the HLJ which causes ulnar-sided wrist pain (Nakamura et al, 2000;Haase et al). In a study based on 2D motion analysis of the lunate, Nakamura et al (2000) suggested that differences in motion, joint loading and injury patterns may contribute to this higher incidence of arthrosis in wrists with Type II lunate.…”

“…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.

We investigated the performance of three tenodesis techniques, modified Brunelli, Corella, and scapholunate axis (SLAM) methods in repairing scapholunate interosseous ligament (SLIL) disruption for a type II wrist using finite element-based virtual surgery and compared the results with those of a previous investigation for a type I wrist. In addition, a comparison of the carpal mechanics of type I and type II wrists was undertaken in order to elucidate the difference between the two types. For the type II wrist, following simulated SLIL disruption, the Corella reconstruction technique provided a superior outcome, restoring dorsal gap, volar gap, and SL angle to within 3.5%, 7.1%, and 8.4%, respectively, of the intact wrist. Moreover, application of the ligament reconstruction techniques did not significantly alter the motion pattern of the type II and type I wrists. For the type I wrist, SLIL disruption resulted in no contact between scaphoid-lunate cartilage articulation, whereas for the type II wrist, some contact was maintained. We conclude that the Corella ligamentous reconstruction technique is best able to restore SL gap, angle, and stability following SL ligament injury for both type II and type I wrists and is able to do so without altering wrist kinematics. Our findings also support the view that type I wrists exhibit row behaviour and type II wrists column behaviour. In addition, our analysis suggests that the extra articulation between the lunate and hamate in a type II wrist may help improve stability following SL ligament injury. Novelty• No previous studies have assessed the performance of scapholunate ligament reconstruction techniques considering the two types (I and II) of wrist.• No previous studies have investigated wrist carpal mechanics both before and after disruption of the SL ligament based on lunate bone morphology.
