[Case control study on T-plate combined with suture anchors for the treatment of Neer â ¡b clavicle fractures].

OBJECTIVE: To compare the clinical efficacy of distal radius T-plate combined with suture anchor and distal clavicle anatomical locking plate combined with suture anchor in the treatment of Neer Ⅱb distal clavicle fracture. METHODS: From June 2014 to June 2018, 42 patients with Neer Ⅱb distal clavicle fractures were retrospectively analyzed. According to different surgical methods, they were divided into the observation group (T-shaped plate combined with suture anchor) and the control group (anatomical locking plate combined with suture anchor). There were 22 patients in the observation group and 20 patients in the control group. In the observation group, there were 13 males and 9 females, aged from 22 to 70 (45.78± 14.44) years old, 12 cases on the left side and 10 cases on the right side, 8 cases of traffic accident injury and 14 cases of fall. In the control group, there were 12 males and 8 females, aged from 24 to 66 (44.17±15.58) years, 13 cases on the left side and 7 cases on the right side, 6 cases of traffic accident injuryand 14 cases of fall. The operation time, intraoperative blood loss and fracture healing time were compared between the two groups, and Constant Murley score was used to evaluate shoulder joint function. RESULTS: The patients in both groups were followed up for 18 to 24 (20.96±2.02) months. The incisions of both groups were healed at stageⅠ. The fracture ends of both groups were bony healed at the last follow up. There was no significant difference in operation time, intraoperative blood loss and fracture healing time between two groups (P>0.05);there was no significant difference in shoulder joint function between two groups at 3 months after operation (P>0.05). CONCLUSION: The two methods can obtain satisfactory results in the treatment of Neer Ⅱb distal clavicle fractures, especially suitable for patients with comminuted distal clavicle fractures or osteoporosis; the clinical effect of the treatment of NeerⅡb distal clavicle fractures with T type distal radius plate combined with suture anchor is satisfactory, which provides another feasible treatment scheme for clinic.

The prevalence and risk factors of acute kidney injury in patients undergoing hip fracture surgery: a meta-analysis.

Acute kidney injury (AKI) was a frequent complication following hip fracture surgery, but recent studies reported inconsistent findings. Our study was aimed at clarifying the prevalence and risk factors of AKI after hip fracture surgery. Pubmed, Embase, and Web of Science were systematically searched from the inception to March 2020 to identify observational studies investigating the prevalence and risk factors of AKI in patients undergoing hip fracture surgery. Pooled prevalence and odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using a random-effects model. Publication bias was evaluated with a funnel plot and statistical test. All the statistical analyses were performed using Stata version 12.0. A total of 11 studies with 16,421 patients was included in the current meta-analysis. The pooled prevalence of AKI in patients undergoing hip fracture surgery was 17% (95%CI, 14%-21%) with substantial heterogeneity (I2 = 95%). Postoperative serum albumin (OR 1.80; 95%CI, 1.38-2.36) was a significant predictor for AKI. Age (OR 1.01; 95%CI, 0.95-1.07) and ACE inhibitors (OR 1.38; 95%CI, 0.92-2.07) were associated with increased the risk of AKI, but the results were not statistically significant. No significant publication bias was identified through statistical tests (Egger's test, p = 0.258 and Begg's test, p = 0.087). In conclusion, our findings indicated that the pooled AKI following hip fracture surgery was approximately 17%. Postoperative serum albumin was a potential significant risk factor for AKI.
