This article presents a novel technique to estimate the mechanical properties of the aluminum composite layer on silicon solar cells by using a hybrid 3-dimensional laser scanning force measurement (3-D LSFM) system. The 3-D LSFM system measures the material properties of sub-layers constituting a solar cell. This measurement is critical for realizing high-efficient ultra-thin solar cells. The ...

We describe two boys with bilateral deformity of the upper end of the radius. The condition appears to predispose to non-traumatic posterior dislocation of the radial head and is associated with posterior bowing of the upper end of the ulna. This problem has not been previously described.

The authors present a unique use of the Z osteotomy in the fifth metatarsal for correction of Tailor bunion. The rotational capabilities of the Z osteotomy are exploited to provide correction of fifth metatarsal lateral bowing and to decrease intermetatarsal angles. The osteotomy is inherently stable, and the design facilitates internal fixation.

Paget’s disease is rare in the Chinese. We present a patient who had a rare monostotic Paget’s disease involving middle diaphysis, distal metaphysis and epiphysis of left femur. Characteristic radiological findings include cortical thickening, coarse trabeculae, osseous expansion and enlargement, and bowing deformity of bone. The patient also had osteo-arthritis of the knee, which can be a comp...

Introduction: Correction of multiplanar bone deformities in children is indicated for prevention of secondary orthopaedic complications. Different problems related to surgical intervention were reported: non-union, delayed union, recurrent deformity, refractures, nerve palsy and pin tract infection. The aim of this study was to show the results of children femur and tibia bowing deformities by ...
