Perioperative Protocol of Ankle Fracture and Distal Radius Fracture Based on Enhanced Recovery after Surgery Program: A Multicenter Prospective Clinical Controlled study.

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.

Modified Anatomic Locking Plate for the Treatment of Posteromedial Tibial Plateau Fractures.

OBJECTIVE: To evaluate the safety and clinical efficacy of a modified anatomic locking plate for the treatment of posteromedial tibial plateau fractures. METHODS: A retrospective study was performed in our department. Between January 2014 and February 2017, 11 patients with posteromedial tibial plateau fractures underwent surgery with the new anatomic locking plate for the posteromedial tibial plateau via the posteromedial approach. The study included 7 male and 4 female patients, with a mean age at the time of the operation of 39 years. During surgery, operation time and blood loss were recorded. Clinical evaluation was performed using the Tegner-Lysholm functional score, the Rasmussen functional score, and the Rasmussen anatomical score. RESULTS: The mean follow-up time of the study was 35 months. The mean interval between the time of injury and the surgery was 7.4 days. Radiological fracture union was evident in all patients at 14 weeks. During surgery, the blood loss ranged from 50 to 150 mL, and the duration ranged from 55 to 90 min. The Tegner-Lysholm functional score ranged from 80 to 96 at the final follow up. Moreover, the final Rasmussen functional score ranged from 25 to 28, and the Rasmussen anatomical score ranged from 15 to 18. The mean knee arc of motion was 137° (range, 122°-153°). Symptoms of knee instability or severe pain were not found in any cases. No flexion contractures or extensor lag was seen. No infection, deep vein thrombosis, or graft site morbidity was seen at the follow up. No case of reduction loss or internal fixation failure was reported during the follow-up. CONCLUSION: With the clinical data of the small-sample-size population (11 patients) during a 19 to 60-month follow-up, the modified anatomic locking plate for the posteromedial tibial plateau proved to be safe and effective and is an adequate fixation method for the treatment of posteromedial tibial plateau fractures.

SP1-mediated upregulation of lncRNA LMCD1-AS1 functions a ceRNA for miR-106b-5p to facilitate osteosarcoma progression.

Growing studies have indicated the involvements of long noncoding RNAs (lncRNAs) in the initiation and progression of various tumors. We aimed to investigated the role of lncRNA LMCD1 antisense RNA 1 (LMCD1-AS1) in osteosarcoma development. We found that LMCD1-AS1 and SP1 were highly expressed in osteosarcoma tissues and cell lines. High levels of LMCD1-AS1 were correlated with positively metastasis and poor clinical prognosis. Moreover, we showed that SP1 can bind to the promoter region of LMCD1-AS1, resulting in its overexpression in osteosarcoma. Functionally, silencing of LMCD1-AS1 suppressed the proliferation, migration, invasion and EMT progress of osteosarcoma cells. Mechanistic studies revealed that LMCD1-AS1 was a sponge of miR-106b-5p activity. LMCD1-AS1 modulated survival of osteosarcoma via targeting miR-106b-5p. Overall, we firstly indicated that LMCD1-AS1 overexpression contributes to osteosarcoma development and poor clinical outcome, suggesting that LMCD1-AS1 may be a novel diagnostic and prognostic biomarker for osteosarcoma and a target for osteosarcoma therapy.

[Strategy and analysis of early management on ninety multiple trauma patients].

OBJECTIVE: To explore the therapeutical effects through investigating the results of multiple traumas treated by means of damage control surgery (DCS) or early total care (ETC). METHODS: The clinical data of 90 patients with severe multiple traumas admitted from June 2001 to June 2007 were analyzed retrospectively. Forty-five patients were classified to the DCS group, 45 patients to the ETC group as a control. These severely injured patients were selected with an ISS > 25 points. RESULTS: Between the two groups, the recovery time of clearance of lactic acid, body temperature, prothrombin time (PT) and activated partial thromboplastin time (APTT) of DCS group was significantly shorter than that of ETC group (P < 0.05). Incidence of complications and mortality in DCS group was significant less than that in ETC group (P < 0.05). No significant differences existed in the volume of bleeding and duration of surgery (P > 0.05). CONCLUSIONS: The concept of DCS could reduce multiple traumas patients' mortality rate and incidence of complications. The indication of DCS should be the combination of physical feature, mechanism and severity of injuries.
