A Retrospective Study of Radiographic Anatomy of Wrist in Chinese Population

Abstract

In wrist pathology, there is a need to establish the normal range of radiographic measurement parameters. Previous study showed that the contralateral wrist might not be valid as a reference for all parameters. There is a lack of literature describing the normal range of wrist radiographic parameters in literature. As a result, a retrospective study was carried out. Patients who underwent standard wrist x-rays during the period February 2012 to February 2013 (one single year) were retrospectively reviewed. 71 patients were included. Scapholunate angle was 54.7˚ (±6.5˚). Scapholunate interval was 2.0 mm (±0.4 mm). Ulnar variance was +1.0 mm (±1.8 mm). Carpal height was 31.8 mm (±3.0 mm). Radial inclination was 25.1˚ (±2.1˚). All 71 patients had 1 sesamoid bone at first metacarpal. 16.9% (12 out of 71) patients had positive cortical ring signs. All these parameters are valuable clinically, especially in monitoring of the wrist disease progression, in the design of wrist implants and for future clinical research.

Normative Data of Carpal Bone Measurements in the Sample Adult Indian Population

“…[12][13][14][15][16] Our study demonstrated capitate length to be 22.3 AE 2.3 which was comparable to various studies in the literature (►Table 4). [12][13][14][15][16] In the studies conducted by Tang et al, 17 Jafari et al, 12 and Vaezi et al, 13 males exhibited significantly greater carpal height, third metacarpal height, and capitate length compared to females. Notably, our study also demonstrated higher values of the above parameter in males compared to females (p < 0.001) with no difference across the age group.…”
