RESUMEN

Background: The enhanced recovery after surgery (ERAS) program is aimed to shorten patients' recovery process and improve clinical outcomes. This study aimed to compare the outcomes between the ERAS program and the traditional pathway among patients with ankle fracture and distal radius fracture. Methods: This is a multicenter prospective clinical controlled study consisting of 323 consecutive adults with ankle fracture from 12 centers and 323 consecutive adults with distal radial fracture from 13 centers scheduled for open reduction and internal fixation between January 2017 and December 2018. According to the perioperative protocol, patients were divided into two groups: the ERAS group and the traditional group. The primary outcome was the patients' satisfaction of the whole treatment on discharge and at 6 months postoperatively. The secondary outcomes include delapsed time between admission and surgery, length of hospital stay, postoperative complications, functional score, and the MOS item short form health survey-36. Results: Data describing 772 patients with ankle fracture and 658 patients with distal radius fracture were collected, of which 323 patients with ankle fracture and 323 patients with distal radial fracture were included for analysis. The patients in the ERAS group showed higher satisfaction levels on discharge and at 6 months postoperatively than in the traditional group (P < 0.001). In the subgroup analysis, patients with distal radial fracture in the ERAS group were more satisfied with the treatment (P=0.001). Furthermore, patients with ankle fracture had less time in bed (P < 0.001) and shorter hospital stay (P < 0.001) and patients with distal radial fracture received surgery quickly after being admitted into the ward in the ERAS group than in the traditional group (P=0.001). Conclusions: Perioperative protocol based on the ERAS program was associated with high satisfaction levels, less time in bed, and short hospital stay without increased complication rate and decreased functional outcomes.

RESUMEN

BACKGROUND: This study aimed to report the surgical techniques and results of treating coronoid process and radial head fracture combined with dislocation of the elbow (terrible triad of the elbow) using a single lateral incision, known as the extensor digitorum communis (EDC) split approach. METHODS: A retrospective analysis was performed of 109 patients with terrible triad of the elbow who had been treated by the authors from January 2013 to December 2019. The participants included 67 males and 42 females, with a mean age of 42.2 years (14-71 years). All participants were treated via a single lateral approach. The coronoid process was fixated with Kirschner wires combined with anterior capsule suture lasso fixation. For the radial head fracture, 58 cases were fixated by AO headless cannulated screw (AO HCS) and 51 cases by acumed radial head replacement. In repair of the lateral collateral ligament (LCL) complex and the common extensor tendon, 28 cases used ETHIBOND suture through bone holes at the humeral lateral epicondyle, and the other 81 cases used suture anchors. No medial collateral ligament was repaired. A total of 46 participants were fixated with a Stryker dynamic joint distractor (DJD) II hinged external fixator to protect the bone and soft tissue. RESULTS: All participants were followed up from 6 to 60 months (mean, 36.1 months). Their elbow range of flexion and extension averaged 123.4°±20.7°, forearm rotation 151.0°±25.6°, and Mayo elbow performance score (MEPS) 92.3±8.8. There were 22 participants (19.5%) with ulnar nerve symptoms, 16 (14.7%) who had elbow stiffness, and 7 underwent secondary surgery, including 6 removals of internal fixation, 5 arthrolyses of the elbow, and 2 ulnar neurolyses. CONCLUSIONS: Coronoid fractures, radial head fractures, and LCL injuries of the terrible triad of the elbow can be treated satisfactorily through a lateral minimal incision, combined with a hinged external fixation if necessary.

RESUMEN

BACKGROUND: The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture. METHODS: The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications. RESULTS: Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P = 0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P = 0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P = 0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P = 0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P = 0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach. CONCLUSIONS: This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

RESUMEN

Chinese yam is the dry rhizome of dioscoreaceae plant. Polysaccharide in yam is one of significant functional components, its pharmacological effects include glucose-lowering, lipid-lowering, anti-tumor, anti-oxidation and enhancing the immune. The effects of nano yam polysaccharide on the metabolism of blood glucose and blood lipid in model rats were systematically investigated in this study. The results showed that the diabetic rat model can been successfully induced by the peritoneal injection of 200mg/kg alloxan. The rats were fed with the high-fat diet for 30d, which could induce a model of hyperlipidemia rat successfully. After the model rats were fed with nano yam polysaccharide of 50mg/ml and 100mg/ml per day for 12d and 30d, respectively. For each nano yam polysaccharide group, the blood glucose level was significantly reduced, the glucose tolerance, glycogen and the content of C-peptide were improved in alloxan rats. Moreover, the symptom of one little and three more in diabetic rats was ameliorated and the contents of TC, TG and LDL-C in the serum for the high fat rats were significantly decreased.

RESUMEN

Low transcondylar fractures of the distal humerus in adults is rarely seen and reported in literatures. It has a bimodal distribution in terms of age, affecting the elderly and younger patients. The fracture is characterized by a very low transverse intra-capsular and extra-articular fracture lines extending from the level of lateral epicondyle to medial epicondyle. Standard elbow plain films and CT scans are crucial and indispensable for diagnosis. Conservative treatment is suitable for undisplaced fractures, patients who are intolerant of anesthesia, or people with advanced dementia. Open reduction and internal fixation (ORIF) is preferred. Parallel and orthogonal plate fixation are widely adopted while some researchers preferred crisscross-type screw fixation or bicolumnar 90-90 plating. In addition, some customized posterolateral plates are specially designed to be able to insert a transverse screw, functioning as lateral support. However, most of the recent researches conducted on low transcondylar fractures of the distal humerus are retrospective studies with relatively lower level of evidence compared to prospective and randomized controlled ones which remain a vacancy in this field. Therefore, further studies comparing the biomechanical properties and clinical prognosis of different configurations of internal fixation or total elbow arthroplasty for the treatment of low transcondylar fractures are needed in the future.
