Volar fixed-angle plate osteosynthesis of unstable distal radius fractures: 12 months results.
With an incidence of about 2-4 per 1,000 residents per year, the distal radial fracture is the most common fracture in the human skeleton. The introduction of fixed-angle plate systems for extension fractures at the radius was evaluated in a prospective study performed at our hospital after selection and acquisition of a new system. The focus of our interest was whether a secondary loss of reduction can be avoided by this plating system. ⋯ Fixed-angle plate osteosynthesis at the distal radius signifies a significant improvement in the treatment of distal radial fractures in terms of restoration of the shape and function of the wrist. The technically simple palmar access, with a low rate of complications, allows exact anatomical reduction of the fracture. The multidirectional fixed-angle system we used provides solid support for the joint surface even in osteoporotic bone and allows simple subchondral placement of screws with sustained retention of the outcome of reduction. Secondary correction loss can be avoided by this procedure. Early mobilisation can be achieved and is recommended.

Evaluation of responsiveness of Oswestry low back pain disability index.
To assess the response of Oswestry disability index (ODI) among patients undergoing caudal epidural steroid injections for lumbosacral radicular pain. ⋯ This study shows that ODI can detect small changes in disability over time in patients undergoing caudal epidural injections for lumbosacral radicular pain. It can also differentiate between small and large changes in the level of disability.

Minimally invasive treatment of pilon fractures with a low profile plate: preliminary results in 17 cases.
To determine the results of "biologic fixation" with a minimally invasive plating technique using a newly designed low profile "Scallop" plate in the treatment of pilon fractures. ⋯ Based on these initial results, it appears that a minimally invasive surgical technique including new low profile plate can decrease soft tissue problems while leading to fracture healing and obtaining results comparable with other more recent series. We believe that this new "Scallop Plate" is effective for the treatment of pilon fractures and should be used in conjunction with a staged procedure in the acute trauma setting.

The prevalence of absence of the palmaris longus: a study in Turkish population.
It is well known that there is a wide variation in the reported prevalence of the palmaris longus (PL) absence in different ethnic groups. This prospective study was conducted to determine the prevalence of absence of PL and correlate it with gender and body side in Turkish population. ⋯ Mishra's second test which involves resisted abduction of the thumb, may be better in demonstration of the PL where the muscle was feebly developed, particularly in women.

The stability of impacted morsellized bone grafts in a metal cage under dynamic loaded conditions: an in vitro reconstruction of a segmental diaphyseal bone defect.
Reconstructions of segmental diaphyseal bone defects with massive allografts are related to complications like nonunion and fractures. A reconstruction of these defects with a cage filled with an impacted morsellized bone graft could be an alternative. The bone graft in these cages should ideally be loaded to prevent resorption. Loading of morsellized bone grafts however can cause instability. The goal of this study was to assess the stability of an impacted morsellized bone graft in a cage under dynamic loaded conditions in an in vitro reconstruction of a segmental diaphyseal bone defect. The second goal was to assess the influence of cage type, washing of the graft and bone-cage fit. ⋯ Morsellized impacted bone graft in a cage is stable in dynamic loaded conditions in an in vitro reconstruction of a segmental diaphyseal bone defect. We believe that this method of reconstruction is a promising alternative for the reconstruction of large diaphyseal bone defects and should be tested relative to its biological merits in animal experiments.
