This report is being filed after the review of the following journal article: j.Sebastiaan souer el.Al (2009), comparison of ao type-b and type-c volar shearing fractures of the distal part of the radius, the journal of bone & joint surgery vol.91(11), pages 2605-2611 (usa) doi:10.2106/jbjs.H.01479.The aim of this article is to investigate the relative incidence of volar marginal articular fractures with and without a concomitant fracture of the dorsal metaphyseal cortex (i.E., we compared type-b and type-c oblique volar marginal articular fractures with volar radiocarpal subluxation) and tested the null hypothesis that there is no difference between these two fractures with regard to wrist function or health status after open reduction and plate-and-screw fixation.Between 2001 to 2004, type b- volar shearing fractures with a total of 20 patients (11 male and 9 female) with a mean age of 49 years (ranges 20-80 years) were included in the study.11 fractures were treated with a 2.4 mm locking compression plate, 5 patients were treated with 3.5-mm locking compression plate, and 2 patients treated with t-shape nonlocking plate.The mean duration of follow-up was unknown.The following complications were reported as follows: 2 patients had an intra-articular step-off base on radiographic evaluation at the 2 year follow-up.Grade-1 radiocarpal arthritis was found in 7 patients.Grade -2 radiocarpal arthritis was found in 2 patients.This report is for a synthes 2.4 mm locking compression plate (lcp), 3.5 mm locking compression plate (lcp) synthes titanium t-shaped nonlocking plate and stainless t-shaped nonlocking plate.This ips captures the following complications: 2 patients had an intra-articular step-off base on radiographic evaluation at the 2 year follow-up.Grade-1 radiocarpal arthritis was found in 7 patients.Grade -2 radiocarpal arthritis was found in 2 patients.This report is for one (1) unk - plates this is report 5 of 8 for (b)(4).A copy of the literature article is being submitted with this medwatch.
