RESUMO
Objective To analyze the clinical efficacy and safety off emoral head replacement(FHR)assisting by the traction table in direct anterior approach(DAA)for the treatment of femur neck fractures in gerontal patients.Methods A retrospective analysis was conducted on 79 elderly patients who under went FHR for femoral neck fractures from March 2019 to July 2020.A total of 42 patients underwent FHR through DAA by using traction table were assigned to the observation group and 37 patients receiving FHR through the PLA to the control group.The perioperative data,follow-up results and complications were compared between the two groups.Results The observation group was significantly superior to the control group in intraoperative blood loss(P<0.05),where as the former was inferior to the latter in preoperative preparation time(P<0.05).There was no significant difference in anesthesia time and operation time between the two groups(P>0.05).The observation group resumed first postoperative standing time,partial-weight bearing walking time and full-weight bearing walk-ing time significantly earlier than control group(P<0.05).Harris score at 1 month after the operation in the observation group were significantly higher than that of the control group(P<0.05),whereas which became not statistical significant between the two groups in 6 months and 1 year(P>0.05).No significant difference was found between the two groups for the incidence of complications(P>0.05).Conclusion DAA-FHR assisting by the traction table for the treatment of femur neck fractures in the elderly was effective and safe,but the preoperative preparation time was longer.
RESUMO
Objective:To investigate the relationship of blood lipid levels with bone mass and fracture risk in elderly patients with type 2 diabetes mellitus (T2DM).Methods:A total of 744 elderly patients with T2DM who were treated in Tangshan Second Hospital from November 2018 to May 2020 were divided into normal bone mass group, low bone mass group and osteoporosis group according to bone mass levels. The total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels in the three groups were compared, and the relationship between lipid indexes and bone mass was analyzed. The risk of fracture was calculated in the low bone mass group, and the relationship between lipid index and fracture risk was analyzed by linear regression. The blood lipid index between subjects with fracture and without fracture in osteoporosis group was compared, and the relationship between blood lipid index and fracture was analyzed by logistic regression.Results:There were significant differences in gender and age among the three groups (χ 2=38.80, F=4.94, P<0.05). The normal bone mass group had the smallest proportion of women and the youngest average age, while the osteoporosis group had the largest proportion of women and the average age. maximum. The LDL-C level in normal bone mass group was higher than those in the low bone mass group and the osteoporosis group, and LDL-C level in the low bone mass group was higher than that in the osteoporosis group ( F=3.38, P<0.05). In the low bone mass group, the risk of systemic fracture was 3.50% (2.40%, 4.10%) and hip fracture was 0.99% (0.80%, 1.20%). Linear regression showed that LDL-C and TG were positively correlated with the risk of systemic fractures in the low bone mass group (LDL-C: B=0.98, P=0.006;TG: B=0.23, P=0.024);TG was positively correlated with the risk of hip fracture in the low bone mass group ( B=0.16, P=0.002). In the osteoporosis group, the levels of HDL-C and LDL-C were lower in the patients with fractures than those without fractures ( t=3.24, P=0.001; t=2.98, P=0.003). Logistic regression analysis showed that higher HDL-C and LDL-C levels were protection factors for fracture risk in the osteoporosis group ( β=-2.73, P=0.009, OR=0.06, 95 %CI=0.04-0.10; β=-0.15, P=0.033, OR=0.83, 95 %CI=0.74-0.99). Conclusion:The relationship of serum lipid index with bone mass and fracture risk in hospitalized elderly T2DM patients is complicated, it is suggested to set individual blood lipid control targets according to the bone mass of patients.
RESUMO
Objective:To investigate the clinical outcomes of homodigital reversed dorsal digital artery island flap innervated by the dorsal digital nerve to repair degloving injury of distal thumb.Methods:From July 2016 to June 2019, a total of 15 cases (15 thumbs) with degloving injury of distal part were admitted to the Department of Hand Surgery, the Second Hospital of Tangshan. Nine males and six females were involved, with an average age of 49 years (range, 41 to 69 years). There were twist injury in eight cases and crush injury in seven cases, with four cases of distal phalanx fracture. The defect dimensions after debridement ranged from 3.5 cm×1.8 cm to 4.6 cm×2.4 cm, and the dimension of the flaps ranged from 3.8 cm×2.1 cm to 5.0 cm×2.7 cm. All defects were repaired using homodigital reversed dorsal digital artery island flap innervated by the dorsal digital nerve. The survival, appearance and sensory recovery of the flaps and function of the injured fingers were observed at the follow-up after operation.Results:All the flaps survived without wound infection and blood supply disorder. The follow-up times ranged from 9 to 22 months (mean, 16 months). There was satisfactory appearance of the flaps with similar color and texture to the surrounding tissue. Fracture healing ranged from 4 to 6 weeks. At final follow-up, the values of static 2-PD test of the flaps ranged from 5 to 10 mm (mean, 7.8 mm). The results of range of motion of injured thumb joints were excellent in nine cases and good in five cases. There was slight linear scar left at the donor area of dorsal thumb.Conclusions:The innervated reversed dorsal digital artery island flap has a simple procedure and minimal donor-site cost, which is especially suitable for elderly patients who refuse to free toe transfers.
