Visual disorders after traumatic brain injury in developmental age.

Visual disorders secondary to TBI are common, often multiple, associated with complex clinical pictures; in developmental age they may particularly interfere with the development process, and compromise the rehabilitation and outcome processes. The aim of this study is to identify visual disorders in 56 post-traumatic children admitted to the Traumatic Brain Injury Unit. All patients underwent a complete clinical, neurological and neuroophthalmological assessment. Correlations were studied between visual disorders and clinical parameters of acute phase, age at trauma, neuroimaging data and outcome, in order to identify possible risk factors for their occurrence. A high incidence was found of complex visual disorders following head trauma: decreased visual acuity, together with a convergence oculo-motor deficit, is the most frequently detected deficit. Trauma severity, indicated by duration of coma, is associated with most of the visual disorders and appears to be the main risk factor conducive to their appearance.

A technical report reviewing the use of the 11-mm Gamma nail: interoperative femur fracture incidence.

Two years after the first large series on the Gamma nail, the authors analyze 119 surgical procedures for proximal femur fractures performed using the 11 mm Gamma nail. The study was performed by 24 surgeons (from six orthopedics departments) at different levels of learning, as in the previous study. The small-sized nail allows an easier surgical procedure and a manual introduction of the nail even in small femurs, as suggested by the previous experience. A careful operative technique and a 2 mm overreaming, which was almost always adopted, explains the decrease in interoperative and postoperative complications (evaluated in 88 cases), compared to the last case report published in 1991. No interoperative shaft fractures occurred in 119 nailings.

The results of a multicenter Italian study on the use of the Gamma nail for the treatment of pertrochanteric and subtrochanteric fractures: a review of 1181 cases.

A total of 1147 pertrochanteric and subtrochanteric fractures, 10 delays in consolidation and non-union, 24 pathologic fractures and osteolysis with the risk of fracture, treated with a gamma nail in 17 Italian departments of traumatology, were collected. In 70% of the patients weight-bearing was allowed during the first week postsurgery; 77% of the patients followed-up recovered the same ability to walk that had preceded trauma. Complications included intraoperative (1.8%) and postoperative (1.1%) diaphyseal fractures, cephalic screw cut out (2.2%), and breakage of the nail (0.4%). There were two cases of infection (0.3%). Most of the complications were related to errors in technique. The safest procedure is constituted by the choice of a nail with a thinner caliber, 2 mm diaphyseal over-reaming, insertion of the nail without the use of a hammer, and distal locking; the cephalic screw must always be inserted in the lower portion of the femoral head.

A case of traumatic plastic deformation of the forearm in the adult.

Traumatic plastic deformation is a rare occurrence in childhood and is exceptional during adult age. The authors report one case of the lesion occurring in a patient aged 20 years; they emphasize the need for adequate treatment, and formulate a pathogenetic hypothesis with a biomechanical basis.
