@#Objective To compare clinical outcomes between the performed titanium locking plate and nickel-titanium memory alloy embracing fixator for the treatment of multiple rib fractures, and to select a better internal fixator for multiple rib fractures. Methods A total of 206 consecutive patients with multiple rib fractures were admitted to Department of Cardiothoracic Surgery in Beijing Luhe Hospital of Capital Medical University from October 2011 to September 2016. According to different treatment strategies, the patients were divided into 2 groups: a performed titanium locking plate group (a titanium plate group, n=105) and a nickel-titanium memory alloy embracing fixator group (an embracing fixator group, n=101). There were 82 males and 23 females with a mean age of 46.5±9.7 years ranging from 23 to 65 years in the titanium plate group, and 83 males and 18 females with a mean age of 44.7±10.3 years ranging from 19 to 63 years in the embracing fixator group. The preoperative data, curative outcomes, visual analogue scale (VAS) and postoperative complications were compared between the two groups. Results There was no statistical difference in the preoperative data between the two groups, and all patients successfully completed the operation. Compared with the embracing fixator group, the incision length and operation time were shorter, intraoperative bleeding and VAS score were less, and curative outcome was better in the titanium plate group. Conclusion The performed titanium locking plate has a great advantage in the clinic, which can be preferred.
Résumé
Objective To study the clinical effect of cemented long stem prosthesis and memory alloy embracing fixator in the treatment of type B2 periprosthetic fractures.Methods Fom April 2014 to April 2016,102 cases of peripheral B2 periprosthetic fractures patients were selected and randomly divided into bone cement long stem prosthesis revision surgery(group A) and revision of cemented long stem prosthesis combined with memory alloy embracing fixator(group B),each group with 51 cases.Clinical efficacy was evaluated according to Beals and Tower criteria,used Harris score to evaluate the hip the joint function,used the Visual Analogue Scale(VAS) score to evaluate the pain,after follow-up of 40 months,the clinical curative effect of 2 groups of patients,fracture healing time,complications and Harris score and VAS score were observed.Results The excellent rate of B group was significantly higher than that of A group,with statistical significance(90.2% vs.72.5%,χ2=5.239,P<0.05).Fracture healing time of group B was shorter than that of group A,with statistically significant ((10.2±2.5) weeks vs.(21.3±8.9) weeks,t=8.575,P<0.05).Harris the score of group B was higher than the group A,with statistically significant((89.9±13.5) points vs.(71.2±18.9) points,t=5.750,P<0.05).VAS score of group B was significantly lower than the group A,with statistically significant((1.23±0.25) points vs.(5.98±1.08) points,t=30.600,P<0.05).There were no complications such as infection,nonunion,loss of reduction and loosening of internal fixation in the 2 groups.Conclusion Revision of cemented long stem prosthesis combined with memory alloy embracing fixator is an ideal methods for the treatment of type B2 periprosthetic femoral fractures,which provides a good initial stability for fracture healing.
Résumé
To compare the effect of surgical and non-surgical treatment for multiple fractured ribs retrospectively, with 30 cases in each group. Patient's length of stay, visual analogue scale ( VAS) pain, independent ambulation time, cost of hospitalization, thoracoplasty degree and the lung ventilation function were evaluated. The results showed that VAS declined obviously in patients of surgical group, length of stay and independent ambulation time were shorter. Compared to the non-surgical group, the maximal voluntary ventilation increased significantly and ref-erral rib reduction was significantly better, but cost of the surgical group was higher. It's an effective treatment for using nickel titanium memory alloy embracing fixator in the treatment of multiple fractured rips, and is worthy of clinical application.
Résumé
Objective To summarize the experience of diagnosis,treatment and clinical effects of Ni-Ti shape memory alloy embracing fixator for severe chest trauma complicated with multiple rib frac-tures.Methods From January 2009 to June 2013,the clinical data of 148 cases with embracing fixator and 47 cases with non-internal fixation were retrospectively analyzed and compared.Results Internal fix-ation was superior to non-internal fixation in hospital stay,pain perception,mechanical ventilation time, pulmonary function recovery and complications(P<0.05).Conclusion Ni-Ti shape memory alloy em-bracing fixator is better than other conservative therapies in the treatment of multiple rib fractures and it's worthy of spreading.
Résumé
Objective To compare the clinical outcome of shape memory alloy (SMA) embra-cing fixator and reconstruction plate fixation in treatment of displaced or comminuted midshaft clavicle fractures. Methods There were 65 patients with displaced or comminuted midshaft clavicle fractures surgically treated with either a SMA embracing fixator or a reconstruction plate. The patients were divided into two groups according to fixation methods, ie, SMA embracing fixator group (30 patients at average age of 28.1 years) and reconstruction plate group (35 patients at average age of 26.1 years). All pa-tients were followed up for mean 12 months and shoulder function was evaluated using shoulder score. Results Compared with reconstruction plate group, SMA embracing fixator had shorter operation time, smaller wound incision and less loss blood (all P < 0.05). However, there was no statistical difference in aspects of hospital stay, cost, JOA shoulder score and bone union rate between two groups (all P > 0.05). Conclusion The internal fixation with SMA embracing fixator is better than reconstruction plate fixation in treatment of midshaft clavicle fractures.
