Project description:BackgroundExtracapsular hip fractures comprise approximately half of all hip fractures and the incidence of hip fractures is exponentially increasing. Extramedullary fixation using a dynamic hip screw (DHS) has been the gold standard method of operative treatment for unstable extracapsular fractures, however, in recent years, intramedullary nails (IMN) have become a popular alternative. IMN versus DHS is continuously discussed and debated in literature. Therefore, the purpose of this systematic review and meta-analysis is to directly compare the peri- and post-operative outcomes of these two techniques to provide an up-to-date analysis of which method of fixation is superior.MethodsThe MEDLINE/PubMed, Embase and Web of Science Database were searched for eligible studies from 2008 to April 2022 that compared peri- and post-operational outcomes for patients undergoing IMN or DHS operations for fixation of unstable extracapsular hip fractures (PROSPERO registration ID:CRD42021228335). Primary outcomes included mortality rate and re-operation rate. Secondary outcomes included operation time, blood loss, transfusion requirement, complication, and failure of fixation rate. The risk of bias and quality of evidence were assessed using the Cochrane RoB 2.0 tool and GRADE analysis tool, respectively.ResultsOf the 6776 records identified, 22 studies involving 3151 patients were included in the final review. Our meta-analysis showed no significant differences between mortality rates (10 studies, OR 0.98; 95% CI 0.80 to 1.22, p = 0.88) or re-operation rates (10 studies, OR 1.03; 95% CI 0.64 to 1.64, p = 0.91) between the two procedures. There were also no significant differences found between complication rates (17 studies, OR 1.29; 95% CI 0.79 to 2.12, p = 0.31) and failure of fixation rates (14 studies, OR 1.32; 95% CI 0.74 to 2.38, p = 0.35). However, DHS operations had a significantly longer operation time (p < 0.0001) and blood loss (p < 0.00001) than IMN operations.ConclusionOverall, based on the outcomes assessed, this review has demonstrated that there is no significant difference in the post-operative outcomes for DHS vs IMN, however a significant difference exists in two of the intraoperative outcomes assessed in this review.
Project description:This study retrospectively analysed 34 patients with ipsilateral hip and femoral shaft fractures treated over a period of 10 years between January 1995 and January 2005. They had an average age of 35 years. Twenty-six (76.47%) of these cases suffered high-velocity trauma (RTA); six others had fallen from a height (17.65%), and two had suffered only minimal trauma (5.88%). Twenty were extracapsular (58.82%) and 14 were intracapsular. They were evaluated with an average follow-up of 28 months, both clinically and radiologically; 26 patients (76.47%) had a good result (Friedman and Wyman score). When the intracapsular fracture was detected postperatively, there was one delayed union and one non-union. When the fracture is diagnosed preoperatively, we recommend reconstruction nail fixation. If the hip fracture is diagnosed intra- or postoperatively following nailing of the shaft, we propose the miss-a-nail technique as an option.
Project description:ObjectiveAngle stable interlocking intramedullary nail (ASIN), a novel technique, has rarely been used for treatment of tibial plateau fractures (TPF). This retrospective study was designed to introduce this novel technique, ASIN, as well as to describe the initial experience and verify the effectiveness when ASIN was used for the management for TPF.MethodsA cohort of 19 cases with closed TPF aged from 18-70 years with at least 23 months follow-up from November 2008 to September 2013 was analyzed retrospectively. All patients underwent the ASIN procedure, which was performed by the same group of surgeons. Perioperative and postoperative parameters like the measurement of radiographic pictures, surgical data, and clinical function were recorded including the changes in treatment. A modified Hohl-Luck radiological and functional score combined with the Hospital for Special Surgery (HSS) score were applied to evaluate the final results and to provide reliable data through the whole procedure when applying the ASIN procedure.ResultsThe patients were followed up regularly for an average of 26.3 (range, 23-34) months. All patients achieved a bony union at an average of 15.1 weeks with no incidences of malunion, nonunion, or infection. Anatomical reduction of the articular surface was obtained in 16 patients. No secondary failure of fixation occurred. The mean postoperative knee flexion was 122.9°. The modified Hohl-Luck radiological and functional score was excellent and good, respectively, in 16 patients. The mean HSS score was 89.4.ConclusionThe angle stable interlocking intramedullary nail system turned out to be a viable alternative protocol in the treatment of tibia plateau fractures and provided satisfactory results, with good fracture reduction, biomechanical fixation, low rates of complications, and passable postoperative knee function.
Project description:With nearly 36% of hand fractures occurring at the metacarpal, a variety of treatment interventions have been developed. Although many nondisplaced metacarpal fractures can be treated with conservative management, displaced, unstable, open, and extra-articular fractures require surgical attention. Compared with open reduction with plate fixation, closed reduction with intramedullary fixation has shown advantages of a simplified technique, minimal soft tissue dissection, and reduced tendon irritation and scar formation. The current study reports on the improved surgical technique associated with the use of novel instrumentation for the closed reduction and intramedullary fixation of extra-articular metacarpal fractures. The design and surgical technique of the premeasured Secure Intramedullary Nail improves fracture fixation, minimizing rotation and backing out, while reducing concerns for soft tissue irritation complications at the base of the metacarpal. Our reported case series suggests procedural efficiency, a low complication rate, and fast recovery for those with indicated extra-articular fractures.
Project description:ObjectiveUnstable femoral neck fractures are typically high-angled shear fractures caused by high-energy trauma. Internal fixation of femoral neck fractures with placement of parallel cannulated screws in an inverted triangle configuration is commonly performed in the clinical setting. This study was performed to investigate the primary results of intramedullary nailing with cannulated screws for the treatment of unstable femoral neck fractures in young and middle-aged patients.MethodsIn total, 96 consecutive patients with no history of hip surgery using inverted triangular cannulated compression screws or construction nails with cannulated screws were reviewed. Their demographic and radiological data were retrospectively collected from our institutional database.ResultsInverted cannulated screws had an excellent effect on decreasing the blood loss volume and incision size, but intramedullary nails exhibited superior advantages in decreasing screw exit and shortening the hospital stays. The Harris hip scores were comparable between the two groups.ConclusionsIntramedullary fixation with cannulated screws has advantages in treating complicated femoral neck fractures. Besides cannulated screws, intramedullary fixation with cannulated screws might be another method to treat unstable femoral neck fractures in young and middle-aged patients. The study was registered in ClinicalTrials.gov. Unique Protocol ID: 11156458. The ClinicalTrial number is NCT03550079.
