ABSTRACT
Objective: To explore the effectiveness of proximal femoral nail antirotation (PFNA) assisted by mesh locator in treatment of intertrochanteric fracture in the elderly. Methods: Ninety-four elderly patients with intertrochanteric fractures admitted between August 2014 and July 2017 were selected as the study subjects. They were randomly divided into trial group (48 cases) and control group (46 cases). In trial group, PFNA was implanted assisted by mesh locator after closed reduction; while in control group, PFNA was implanted by conventional method. There was no significant difference between the two groups in terms of gender, age, cause of injury, time from injury to admission, fracture side and classification, and medical complications ( P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, hospital stay, incision length, and complications were recorded. Visual analogue scale (VAS) was used to evaluate the degree of pain at 3 days after operation, and Harris score was used to evaluate hip function before operation and at 3, 6, and 9 months after operation. Results: Compared with control group, the operation time and incision length of trial group shortened, the blood loss and fluoroscopy times reduced, the pain after operation alleviated obviously; the differences between the two groups were significant ( P0.05). The patients in both groups were followed up 9-12 months, with an average of 10.6 months. X-ray films showed that the fractures healed in both groups, and the healing time in control group was (11.2±3.2) weeks, while that in trial group was (11.6±2.9) weeks, showing no significant difference between the two groups ( t=1.262, P=0.120). There was no significant difference in Harris score between the two groups before operation and at 3, 6, and 9 months after operation ( P>0.05). There was 1 case of incision infection, 2 cases of coxa vara, and 1 case of pressure ulcer in trial group, and the incidence of complications was 8.3%. There was 1 case of coxa vara, 2 cases of pressure ulcer, and 1 case of internal fixation loss in control group, and the incidence of complications was 8.7%. There was no significant difference in the incidence of complications between the two groups (χ2=0.783, P=0.112). Conclusion: It is feasible to implant PFNA assisted by mesh locator in treatment of intertrochanteric fracture in the elderly. Compared with the traditional operation, it can shorten the operation time, shorten the incision, and relieve the pain after operation.
ABSTRACT
BACKGROUND:The therapeutic regimen of intraarticular calcaneal comminuted fractures commonly selects plate and screw fixation. However, for case of posterosuperior calcaneal fracture, the weakness of achil es tendon stretch and plate screw fixation results in difficulty or maintenance of reduction. OBJECTIVE:To investigate the therapeutic effects of open reduction and internal fixation with steel screw and Steinmann pins for comminuted calcaneal intra-articular and posterosuperior fractures. METHODS:From December 2009 to December 2013, forty patients with fractures of comminuted calcaneal posterosuperior fractures were randomly divided into two groups. In the control group, patients were treated by open reduction and internal fixation by plate screw only. In the experimental group, patients were treated by open reduction and internal fixation by combination of plate screw and Steinmann pin. The Gissane and Bohler angles of the calcaneus were measured from lateral radiograph before and 4 weeks after surgery, and the MARYLAND score was assessed at the last fol ow-up. Gissane and Bohler angle and MARYLAND score were compared in each group and among different groups. RESULTS AND CONCLUSION:Al patients were fol owed up for 9-23 months. BOHLER and GISSANE angles were significantly bigger at 4 weeks after surgery compared with pre-treatment in both groups (P<0.05). BOHLER and GISSANE angles were significantly bigger in the experimental group than in the control group at 4 weeks after surgery (P<0.05). During final fol ow-up, the average score by MARYLAND Foot Score was 78 in the experimental group and 67 in control group, with their excellent and good rate of 80%and 73%. The excellent and good rate was significantly higher in the experimental group than in the control group (P<0.05). These data indicated that open reduction and internal fixation with combination of plate screw and Steinmann pin has better efficacy in treatment of the comminuted calcaneal intra-articular and posterosuperior fractures compared with plate and screw fixation alone. Their fixation is firm. Functional exercise can be performed earlier. Postoperative recovery of function of the affected limbs is better than plate and screw fixation alone.
ABSTRACT
BACKGROUND:Mason II type and III type radial head fractures with massive bone are mainly treated by open reduction and metal fixation, but metal implants have to be removed in the second operation, which increased patients’ travail and financial burden. Absorbable screw/rod also can be used to treat radial head fractures, and has its special advantages due to the low price and no second operation. OBJECTIVE:To compare the clinical therapeutic effects of absorbable rod and Herbert screw for the treatment of Mason II or III type radial head fractures. METHODS:A total of 80 patients with Mason II and III type radial head fractures were equal y assigned to experimental and control groups. They received open reduction and internal fixation. The experimental group was treated with absorbable rod and the control group received Herbert screw. RESULTS AND CONCLUSION:A total of 79 patients were fol owed up for averagely 34 months. No significant difference in average operative time, fracture healing time, Broberg and Morrey elbow scores and incidence of complications was detected between the experimental and control groups (P>0.05). However, treatment costs were lower in the experimental group than in the control group (P<0.05). Results indicated that the therapeutic effects between absorbable rod and Herbert screw for Mason II or III type radial head fractures were similar. However, absorbable rod for radial head fractures can avoid the second operation for removal of the implant. Therefore, we recommend absorbable rod in the choice of internal fixation materials.
ABSTRACT
BACKGROUND:At present, the methods of treating unstable comminuted radial head fractures contain open reduction and internal fixation and metal prosthesis replacement. There were success cases treated by the two methods, but some shortcomings simultaneously existed. OBJECTIVE:To compare the clinical therapeutic effects of replacement of the radial head with metal prosthesis with open reduction and internal fixation for the treatment of unstable comminuted radial head fractures. METHODS:A prospective randomized control ed analysis was performed in 45 cases of unstable comminuted radial head fractures. These cases received open reduction and internal fixation and metal prosthesis replacement. This study compared the Broberg and Morrey elbow joint function score and the incidence of complications after fixation, and performed statistical analysis. RESULTS AND CONCLUSION:The subjects were fol owed up for 1-5 years, averagely 2.8 years. According to Broberg and Morrey scores, the average score was 90.1 and the incidence of complications was 13.6%in the prosthesis replacement group. The average score was 76.8 and the incidence of complications was 47.9%in the open reduction. Significant differences were visible between the two groups (P<0.01). Compared with the open reduction group, prosthesis replacement for unstable comminuted radial head fractures obtained better joint function and lower incidence of complications.
