We present models of localized plastic deformation inside Persistent Slip Band channels. First, we investigate the interaction between screw dislocations as they pass one another inside channel walls in copper. The model shows the mechanisms of dislocation bowing, dipole formation and binding, and finally dipole destruction as screw dislocations pass one another. The mechanism of (dipole passin...

BACKGROUND Proper limb and component alignments as well as soft tissue balance are vital for the longevity and optimal long-term outcomes of total knee arthroplasty (TKA). This procedure is technically demanding in patients with Ranawat type-II valgus arthritic knees with marked coronal femoral bowing. Computer-assisted surgery (CAS) and intra-articular bone resection with TKA are the treatment...

Abstract In the present study, 5 different consolidants were tested on marble varieties preliminarily subjected to artificial weathering, evaluate their consolidating effectiveness and thermal behavior after consolidation, in terms of residual strain heating–cooling cycles dry wet condition tendency bowing. Treatments based ethyl silicate, with without a coupling agent improve performance calci...

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 ...
