[Quantification of changes in the external morphology of the back by means of surface topography based on structured light in idiopathic scoliosis in adolescents after a year of treatment with orthopedic corse].

Background: To quantify the morphological changes in the surface of the back of adolescents with idiopathic scoliosis as a result of treatment with braces and to correlate them with radiographic changes.

Material And Methods: An analytical, cohort, prospective study on a sample of 31 adolescents with idiopathic scoliosis. We divided them into two groups: eleven treated with braces and twenty without them.

Risk factors related to adjacent segment degeneration: retrospective observational cohort study and survivorship analysis of adjacent unfused segments.

Object: Adjacent segment disease (ASD) has been described as a frequent complication after a lumbar spinal fusion procedure, though its incidence and the factors related to its appearance are not well established. The radiographic signs that identify ASD in unfused segments may be a consequence of biomechanical changes induced by the fusion procedure. This study sought to analyse the incidence of radiographic changes (radiographic ASD) in all adjacent unfused segments, the clinical changes that require a second procedure (clinical ASD), and the risk factors of their appearance evaluated at different follow-up times.

Positioning of the cross-stitch on the modified Kessler core tendon suture.

Cryopreserved human tendons were sutured with different variations of a modified Kessler-type grasping suture in a series of different designs in order to assess the influence of the distance between the cross-stitch on the core suture (5 and 10 mm from the cut tendon edge) on the peripheral suture. An original mathematical model was employed to explain the mechanical behavior (strength, deformation, and distribution of load) of the different suture designs. The effect of the peripheral epitendinous suture, combined with the distance of the core suture, was evaluated.

[Dome shaped osteotomy combined with transposition of the ulnar nerve as a treatment for post-traumatic ulnar valgus in a pediatric patient].

A sequel of supracondylar fractures of distal humerus in children is the angular deformity. It is usually more frequent cubitus varus, but there are reported cases of cubitus valgus. The latter may be the cause of the occurrence of a late ulnar nerve neuropathy, which will require treatment.

Ossifying fibroma of long bones in adults: a case report.

Ossifying fibroma (osteofibrous dysplasia) is a rare fibro-osseous lesion made up of fibrous tissue with woven bone formation. It is most commonly found in the tibia and fibula of children ten years of age or younger. The most important differential diagnosis is monostotic fibrous dysplasia, which is radiologically similar but without woven bone rimmed by active osteoblasts like ossifying fibroma on histological examination.
