Selective non-operative management for penetrating abdominal injury in a Dutch trauma centre.

INTRODUCTION: Selective non-operative management (SNOM) for penetrating abdominal injury (PAI) is accepted in trauma centres in South Africa and the US. Owing to the low incidence of gunshot wounds (GSWs) in Western Europe, few are inclined to practise SNOM for such injuries although it is considered for stab wounds (SWs). This study evaluated the outcome of patients admitted to a Dutch level 1 trauma centre with PAI. METHODS: A retrospective study was undertaken of all PAI patients treated over 15 years. In order to prevent bias, patients admitted six months prior to and six months following implementation of a treatment algorithm were excluded. Data concerning type of injury, injury severity score and treatment were compared. RESULTS: A total of 393 patients were included in the study: 278 (71%) with SWs and 115 (29%) with GSWs. Of the 178 SW patients in the SNOM group, 111 were treated before and 59 after introduction of the protocol. The SNOM success rates were 90% and 88% respectively (p=0.794). There were 43 patients with GSWs in the SNOM cohort. Of these, 32 were treated before and 11 after implementation of the algorithm, with respective success rates of 94% and 100% (p=0.304).The protocol did not bring about any significant change in the rate of non-therapeutic laparotomies for SWs or GSWs. However, the rate of admission for observation for SWs increased from 83% to 100% (p<0.001). There was a decrease in ultrasonography for SWs (from 84% to 32%, p<0.001) as well as for GSWs (from 87% to 43%, p<0.001). X-ray was also used less for GSWs after the protocol was introduced (44% vs 11%, p=0.001). CONCLUSIONS: SNOM for PAI resulting from either SWs or GSWs can be safely practised in Western European trauma centres. Results are comparable with those in trauma centres that treat high volumes of PAI cases.

Clinical and non-clinical aspects of distal radioulnar joint instability.

Untreated distal radioulnar joint (DRUJ) injuries can give rise to long lasting complaints. Although common, diagnosis and treatment of DRUJ injuries remains a challenge. The articulating anatomy of the distal radius and ulna, among others, enables an extensive range of forearm pronosupination movements. Stabilization of this joint is provided by both intrinsic and extrinsic stabilizers and the joint capsule. These structures transmit the load and prevent the DRUJ from luxation during movement. Several clinical tests have been suggested to determine static or dynamic DRUJ stability, but their predictive value is unclear. Radiologic evaluation of DRUJ instability begins with conventional radiographs in anterioposterior and true lateral view. If not conclusive, CT-scan seems to be the best additional modality to evaluate the osseous structures. MRI has proven to be more sensitive and specific for TFCC tears, potentially causing DRUJ instability. DRUJ instability may remain asymptomatic. Symptomatic DRUJ injuries treatment can be conservative or operative. Operative treatment should consist of restoration of osseous and ligamenteous anatomy. If not successful, salvage procedures can be performed to regain stability.
