Clinical long-term results of radial head arthroplasty in comminuted radial head fractures.

Modern radial head prostheses have recently become more common in the treatment of comminuted radial head fractures. The goal of this study was to evaluate how well the EVOLVE modular metallic radial head implant prosthetic restores the functional range of motion and stability of the elbow. 30 patients with comminuted radial head fractures received an arthroplasty with an EVOLVE prosthesis in our institution.

Long-term results of olecranon fractures treated using the XS nail® system.

Purpose: Olecranon fractures are particularly vulnerable to distraction and subsequent fracture dislocation due to the high tensile forces. Surgical treatment aims at reducing the fracture and restoring the anatomical joint surface condition, as well as neutralizing the strain inhibiting fracture healing. The XS nail® (Intercus GmbH, Bad Blankenberg, Germany), an intramedullary implant exerting compression across the entire fracture surface, unlike plates, leaves a minimal extra-cortical profile, and can be secured with threaded locking wires, thereby retaining the anatomical reduction without displacement or steps within the articular surface, which was often found in tension band wiring.

Pursuing More Aggressive Timelines in the Surgical Treatment of Traumatic Spinal Cord Injury (TSCI): A Retrospective Cohort Study with Subgroup Analysis.

Background: The optimal timing of surgical therapy for traumatic spinal cord injury (TSCI) remains unclear. The purpose of this study is to evaluate the impact of "ultra-early" (<4 h) versus "early" (4-24 h) time from injury to surgery in terms of the likelihood of neurologic recovery.

Methods: The effect of surgery on neurological recovery was investigated by comparing the assessed initial and final values of the American Spinal Injury Association (ASIA) Impairment Scale (AIS).

Bizarre dermal armour suggests the first African ankylosaur.

Ankylosauria is a diverse clade of armoured dinosaurs whose members were important constituents of many Cretaceous faunas. Phylogenetic analyses imply that the clade diverged from its sister taxon, Stegosauria, during the late Early Jurassic, but the fossil records of both clades are sparse until the Late Jurassic (~150 million years ago). Moreover, Ankylosauria is almost entirely restricted to former Laurasian continents, with only a single valid Gondwanan taxon.

Use of an Intramedullary Locking Nail for the Treatment of Patella Fractures.

PURPOSE OF THE STUDY Treatment of patella fractures has always been difficult; especially in older patients. The aim of this study was to investigate the XS nail in the treatment of patella fractures. MATERIAL AND METHODS 49 fractures could be registered and reevaluated with a standardized questionnaire.
