There is ambiguity concerning the nomenclature and classification of fractures of the ring of the second cervical vertebra (C2). Disruption of the pars interarticularis which defines true traumatic spondylolisthesis of C2, is often wrongly called a pedicle fracture. Our aim in this study was to assess the influence of asymmetry on the anatomical and functional outcome and to evaluate the criteria of instability established by Roy-Camille et al. We studied the plain radiographs and CT scans of 24 patients: 13 were judged to be asymmetrical, ten were considered unstable and 14 stable. Treatment was with a Minerva jacket in 15 fractures and by operation in nine. Surgery was undertaken in patients with severe C2 to C3 sprains. One patient with an unstable lesion refused operation and was treated conservatively with a poor radiological result. Our study showed that asymmetry of the fracture did not affect the outcomes of treatment and should not therefore influence decisions in treatment. The criteria of Roy-Camille seem to be reliable and useful. We prefer the posterior approach to the cervical spine, which allows both stabilisation of the fracture and correction of a local kyphosis.
Introduction. Soft tissue defects in the distal leg and foot are challenging conditions for reconstruction. The widely used reverse sural fascio-cutaneous flap (RSFCF) has been reported with large variation in complication frequency. Some authors reported higher complications in the diabetic population when compared with trauma patients. We compared the reliability of the RSFCF in treating such defects among both populations. Methods. This is a retrospective series with a prospective data collection of 24 patients (11 with type 2 diabetes and 13 in trauma settings) treated with an ipsilateral RSFCF for soft tissue defects of the distal leg and the rear foot. Healing events and complications were recorded and compared for both groups. The mean follow-up was 32 months. Results. Diabetic group versus trauma group showed the following results; mean flap healing time of 24 versus 22 days, donor site healing time of 14 versus 16 days, 1 total flap necrosis in both groups, 3 versus 2 cases of skin edge necrosis, 2 cases of temporary venous congestion in both groups, and 8 versus 10 cases of transient hypoesthesia of the lateral border of the foot. No infection was encountered in both groups and no recurrence of infection in the primary infected diabetic patients. Conclusions. We found the RSFCF to be useful, reproducible, and reliable in treating soft tissue defects with a very low frequency of serious complications. Diabetic patients were found to have similar outcomes when compared with trauma patients. Therefore, diabetes might not be a major factor of flap failure. Levels of Evidence: Level III: Therapeutic
The placement of the patellar component during TKA differs from one patella to another. Thus, by defining the OCPP on a patient-by-patient basis, the surgeon should be able to reproduce the functional anatomy of the native patella.
The patella remains one of the main sources of post-operative complication following total knee arthroplasty surgery. Optimal positioning of the patellar component is still a controversy with no clear-cut guidelines. Instead of choosing an empirical position, we described a novel surgical technique to better locate the patellar button based on the individual patellar anatomy of each patient.
Introduction: Osteonecrosis of the femoral head (ONFH) remains a therapeutic challenge for patients undergoing total hip arthroplasty (THA). The majority of these patients are young with high functional demand, and show an increased risk of dislocation following surgery than patients with osteoarthritis. The use of double mobility cup (DMC) has been linked with lower rates of complications when compared to conservative cups; however, the literature is scarce over DMC results in patients with ONFH. The aim of the study is to report the early outcomes of patients with ONFH treated with THA-DMC. Materials: A retrospective analysis of patients suffering from ONFH who underwent THA using DMC (THA-DMC) from 2006 to 2015 were evaluated for functional status and risk of post-operative complications. Thirty THA-DMC in 26 patients with a mean follow-up of 51 months were evaluated clinically (modified Hip Harris Score) and radiologically. Results: The mean age of the included patients was 54.9 years. At final follow-up, the mean modified Hip Harris score was 98.7 ± 2.7 and no dislocation episodes or revision surgeries were recorded. The radiological assessment revealed no signs of migration/tilting, radiolucent lines, periprosthetic osteolysis or heterotopic ossification over the DMC component and the femoral stem. The survival rate over 51 months of follow-up was 100%. Discussion: The use of the new generation of dual mobility cup in patients with ONFH showed excellent functional early results with no major complications such as dislocation.
