<p><strong>Objective: </strong>To<strong> </strong>investigate the clinical effects of patients with femoral prosthesis fracture phenomena after the application of locking plate fixation for hip replacement surgery. <strong>Method: </strong>78 cases of postoperative patients with periprosthetic femoral fracture phenomenon after hip replacement were selected and divided randomly into a control and treatment group, respectively, with an average of 39 cases per group. The control group was treated with the shape memory alloy inner ring fixing technology whereas the locking plate fixation was applied for the treatment group. <strong>Result:</strong> Fracture treatment around the femoral prosthesis in patients of treated group was better in comparison to the control group. Significantly, the treatment group revealed shorter duration of hospitalization, the recovery of limb weight-bearing capacity and the healing process as compared to  the control group. Harris scores were significantly higher in the treated group in contrast to the control group. Additionally, lower adverse reaction rate was found in the treatment group as compared to the control group. <strong>Conclusion:</strong> Obviously, patient who have femoral periprosthetic fracture phenomena after receiving hip replacement were likelihood to be treated with the locking plate fixation technique.</p>

Fixation System

Background. Intra-capsular fractures of the femoral neck in young patients are almost always treated with surgical fixation to preserve the native hip anatomy and biomechanics. Multiple Cannulated hip screws and the sliding hip screw have been the hallmark fixation devices for these injuries. The use of locking cannulated hip screws to a side plate was developed to mitigate the biological and mechanical downfalls of these devices. To report the outcome following the use of a locking plate fixation system in the management of intracapsular fractures of the femoral neck in young patients. Material and methods. A case series study of all the patients treated in our institution between 2014 and 2017. All eligible patients with hip intracapsular fractures aged between 18 and 65 were treated with a proximal locking hip plate system. The main reported outcomes were union rate, failure of fixation, and development of avascular necrosis of the femoral head. Results: Fifty-six patients (36 men and 20 women) at a mean age of 39.1 years (range 20-65 years) completed 24 months’ follow-up. Mean time to surgery was 16 hours. No intraoperative complications were reported. The mean time to union was 15.9 weeks (range 12-23). Three patients (5.3%, one Garden type III, and two type IV) did not achieve union at 6 months. Two patients had revision surgery with valgus osteotomy and the third patient required total hip replacement because of screw penetration. Five patients (8.9%) developed avascular necrosis of the femoral head (2 patients Garden type III, and 3 patients Garden VI). Only two patients required conversion to total hip replacement. Conclusions. 1. The results in this study showed lower rates of non-union, AVN and secondary operation as compared to published data on both SCH and DHS. 2. It also compares favorably with results reported for dy­namic locking screw systems. 3. The study had few li­mitations, including lack of comparative groups. Also, when considering fracture classification subgroups, the unstable fracture pattern had higher rates of non-union and AVN. 4. This calls for a further larger number of studies dedicated to these fracture categories to ascertain long-term outcome with this type of fixation.

AbstractFailure in the treatment of P. aeruginosa, due to its broad spectrum of resistance, has been associated with increased patient mortality. One alternative approach for infection control is quorum quenching which was found to decrease virulence of such pathogen. In this study, the efficiency of a recombinant Ahl-1 lactonase formulated as a hydrogel was investigated to control the infection of multidrug resistant (MDR) P. aeruginosa infected burn using a murine model. The recombinant N-acylhomoserine lactonase (Ahl-1) was formulated as a hydrogel. To test its ability to control the infection of MDR P. aeruginosa, a thermal injury model was used. Survival rate, and systemic spread of the infection were evaluated. Histopathological examination of the animal dorsal skin was also done for monitoring the healing and cellular changes at the site of infection. Survival rate in the treated group was 100% relative to 40% in the control group. A decrease of up to 3 logs of bacterial count in the blood samples of the treated animals relative to the control group and a decrease of up to 4 logs and 2.3 logs of bacteria in lung and liver samples, respectively were observed. Histopathological examination revealed more enhanced healing process in the treated group. Accordingly, by promoting healing of infected MDR P. aeruginosa burn and by reducing systemic spread of the infection as well as decreasing mortality rate, Ahl-1 hydrogel application is a promising strategy that can be used to combat and control P. aeruginosa burn infections.

Abstract Background and hypothesis The typical anterolateral approach is widely used to treat proximal humerus fractures with lateral locking fixation. However, lateral fixation cannot completely avoid medial reduction loss and varus deformity especially in the cases of an unstable medial column. We present a novel medial surgical approach and technique together with a minimally invasive lateral locking plate to fix proximal humerus fractures with an unstable medial column. Materials and methods We performed an anatomical study and reported 8 cases of proximal humerus fractures with unstable medial columns treated with plate fixation through a minimally invasive anterolateral approach and medial approach. All surgeries were performed by the same single surgeon. Patients were followed clinically and radiographically at 1, 3, 6, and 12 months postoperatively. Results There was a safe region located at the medial part of the proximal humerus just beneath the articular surface. An anatomical medial locking proximal humerus plate could be placed in the medial column and did not affect the axillary nerve, blood supply of the humeral head, or stability of the shoulder joint. Successful fracture healing was achieved in all 8 cases. The function and range of motion of the shoulder joint were satisfactory 24 months postoperatively, with an average Constant score (CS) of 82.8. No reduction loss (≥ 10° in any direction), screw cutout, nonunion, or deep infection occurred. Conclusions The combined application of medial anatomical locking plate fixation and minimally invasive lateral locking plate fixation is effective in maintaining operative reduction and preventing varus collapse and implant failure in proximal humerus fractures with an unstable medial column.

Level Of Evidence

The purpose of this systematic review is to assess the prevalence of complications following volar locking plate fixation of distal radial fractures. A computer-based search was carried out using EMBASE and PUBMED/MEDLINE. Only prospective comparative and prospective cohort studies that presented data concerning complications after treatment of distal radial fractures with a volar locking plate in human adults with a minimal follow-up of 6 months were included. Two quality assessment tools were used to assess the methodological quality of the studies (level of evidence rating according to the Oxford Centre of Evidence Based Medicine and the modified version of the Cochrane Bone, Joint and Muscle Trauma Group’s former quality assessment tool). Thirty three studies were eligible for final assessment. Most complications were problems with nerve and tendon function as well as complex regional pain syndrome. With an overall complication rate of 16.5%, most of which were ‘minor’ complications and low rates of nonunion and malunion, volar locking plate fixation can be considered a reasonably safe treatment option for patients with distal radial fractures.
