The use of total-body computed tomography (CT) scanning in the evaluation of multiply injured patients is increasing, and their liberal use has stirred debate as to the added benefit relative to the risk of radiation exposure and inappropriate use of limited healthcare resources. Findings unrelated to the clinician's reasons for requesting the radiological examination are often uncovered due to the comprehensive nature of the evaluation at a trauma centre. However, some of these findings are outside the expertise of the trauma team who initially organised the scan and this may lead to uncertainty over who is best qualified to follow-up the incidental finding. We aim to evaluate the frequency of incidental findings on whole body trauma CT scans in a consecutive series of trauma admissions to our unit. ⋯ Our findings reflect the literature noting that incidental findings are increasingly common due to the central diagnostic role of CT imaging in trauma care, but also due to advances in imaging techniques and quality. In keeping with published literature, we note that increased age is associated with an increased incidence of "incidental findings" and this will continue to rise with the ageing population and the mandatory nature of trauma CTs.

Recurrent patellar instability can be a source of continued pain and functional limitation in the young, active patient population. Instability in the setting of an elevated tibial tubercle-trochlear groove (TT-TG) distance can be effectively managed with a tibial tubercle osteotomy. At the present time, clinical outcome data are limited with respect to this surgical approach to patellar instability. ⋯ For the management of recurrent patellar instability in the setting of an increased tibial tubercle-trochlear groove distance, a corrective tibial tubercle osteotomy is an effective treatment modality to reliably prevent patellar instability while reducing pain and improving function in this cohort of young, active patients.

Comparative Study
Surgical exposures and options for instrumentation in acetabular fracture fixation: Pararectus approach versus the modified Stoppa.
As an alternative to the modified Stoppa approach, the Pararectus approach is used clinically for treatment of acetabular fractures involving the anterior column. The current study assessed the surgical exposure and the options for instrumentation using both of these approaches. ⋯ Compared to the modified Stoppa, the Pararectus approach facilitates a greater surgical access in the false pelvis, provides versatility for fracture fixation in the posterior pelvic ring and allows for the option to extend the approach without a new incision.

Isolated fractures of the lower extremity are relatively common injuries while multifocal injuries resulting from high-energy trauma are less frequently encountered. Our objectives are to characterise patients who sustained multiple noncontiguous fractures and open fractures of the lower extremity, report the incidence of major complications, and identify factors that may contribute to complications and unplanned re-operations. ⋯ Patients with multiple non-contiguous lower extremity injuries associated with open fractures can expect complications including non-unions, deep infections, and painful implants. Nearly half of the patients will need further operative treatment.

Pre-operative digital templating allows the surgeon to foresee any anatomical anomalies which may lead to intra-operative problems, and anticipate appropriate instruments and implants required during surgery. Although its role is well-established in successful elective total hip arthroplasty, little work has been done on its use in hip hemiarthroplasty in neck of femur fractures. We describe our initial experience of digital templating in 40 consecutive patients who have undergone cemented hip hemiarthroplasty, assessing templating accuracy between templated implant sizes to actual implant sizes. 81% of implanted heads were templated to within two head sizes, and 89% of implanted stems were templated to within two sizes. ⋯ D. 4.4). Digital templating is a useful adjunct to the surgeon in pre-operative planning of hip hemiarthroplasty in the restoration of leg length and femoral offset. However, its accuracy is inferior to that of elective total hip arthroplasty.
