Comparison of the clinical efficacy of a femoral neck system versus cannulated screws in the treatment of femoral neck fracture in young adults

Abstract Background To compare the clinical efficacy of a femoral neck system (FNS) and cannulated screws (CS) in the treatment of femoral neck fracture in young adults. Methods Data from 69 young adults, who were admitted for femoral neck fracture between March 2018 and June 2020, were retrospectively analyzed. Patients were divided into two groups according to surgical method: FNS and CS. The number of intraoperative fluoroscopies, operative duration, length of hospital stay, fracture healing time, Harris score of hip function, excellent and good rate of hip function, and postoperative complications (infection, cut out the internal fixation, nail withdrawal, and femoral neck shortening) were compared between the two groups. Hip joint function was evaluated using the Harris Hip Scoring system. Results All 69 patients had satisfactory reduction and were followed up for 12–24 months, with a mean follow-up of 16.91 ± 3.01 months. Mean time to fracture healing was13.82 ± 1.59 and 14.03 ± 1.78 weeks in the FNS and CS groups, respectively. There was a statistical difference in the number of intraoperative fluoroscopies between the 2 groups (P = 0.000). There were no significant differences, in operation duration, hospital length of stay, fracture healing time, complications, Harris Hip Score for hip function and excellent and good rate between the two groups (P > 0.05). The incidence of complications was 6.1%(2/33) in the FNS group lower than 25%(9/36) in the CS group, a difference that was statistically significant (P = 0.032). At the last follow-up, the Harris Hip Score of the hip joint in the FNS group was 90.42 ± 4.82and 88.44 ± 5.91 in the CS group. Conclusions Both treatment methods resulted in higher rates of fracture healing and excellent hip function. Compared with CS, the FNS reduced the number of intraoperative fluoroscopies, radiation exposure to medical staff and patients, and short-term complications including femoral neck shortening and bone nonunion.

Objective To examine the imaging evidence of the use of percutaneous compression plate (PCCP) in promoting femoral neck fracture healing compared with cannulated screws (CS). Methods This retrospective study enrolled patients with femoral neck fractures undergoing internal fixation procedures. The patients were divided into a PCCP group and a CS group with imaging as the primary outcome and Harris hip score (HHS) as the secondary outcome. Results This study included 162 patients: 80 in the PCCP group and 82 in the CS group. There were no significant differences between the patients in their preoperative baseline characteristics. Patient follow-up ranged from 24–56 months (mean 30.7 months). Differences in reduction quality, screw slipping, neck shortening and avascular necrosis (AVN) were not significant between the two groups. There were significant differences between the treatment groups in bone absorption, nonunion, healing time, screw withdrawal and fixation failure in favour of the PCCP group. Postoperative HHS at 6 and 12 months were significantly better for the PCCP group than the CS group, but the differences were not significant at 24 months and last follow-up. Conclusion Stable internal fixation with dynamic compression was the key to PCCP promoting femoral neck fracture healing.

Abstract Background: Femoral neck fracture is a serious injury in adults with significant functional consequences.Internal fixtion is an established treatment for femoral neck fractures in young adult patients .However, the risk of complications following fixation has plague orthopedists for decades.In all femoral neck fracture ,Pauwels type-III femoral neck fractures with a large vertical shear force were more likely to cause clinical failure.The aim of this study is to intruduce a new surgical technique for the treatment of this fracture according to the morphology of the fracture using the combination of Pauwels screw and inverted triangle cannulated screws(PSTCS)，and report the clinical effects in a prospective cohort of 14 patients.Methods: From June 2017 to June 2019, a total of 14 patients (8 males and 6 females ) with Pauwels type-III femoral neck fracture underwent the surgical treatment of PSTCS according to the morphologyical types of fracture in clinical operation in our department. Patients were allowed to perform contraction exercises of quadriceps femoris on postoperative day1, passive flexion and extension exercises postoperative day 2 onwards, and active flexion and extension exercises postoperative day 7 onwards. Patients were allowed for partial-weight bearing walking postoperative 1month onwards with axillary crutches. After one month AP and lateral radiograph were taken. Full ambulation was permitted until the presence of radiological consolidation.Intraoperative (Operative duration,Blood loss),postoperation(Fracture union time,The Harris Hip Score,Visual analog score) were record for comparison.Results: All patients were followed up for at least 12 months.In the end point of the follow up ,12 of the 14 patients (85.7%)with pauwels type-III femoral neck fractures had achieved satisfactory hip function. Operative duration was a mean of 49.5 ±10.4 minutes.Intraoperative blood loss was between 26 and 110 ml (mean, 44.4±20.6ml) and without intraoperative blood transfusion . The Harris Hip Score was between 64 and 95(mean,87.6±8.9).Fracture healing was observed in all patients according to the X-ray . No internal fixation was loosened or screw cut-out in the follow-up period.The femoral head necrosis was observed in 1 patient in this study. In addition, there was no obvious fracture displacement, femoral neck shortening, or hip varus. Conclusions: The study showed that PSTCS can provide a satisfactory clinical outcomes for treatment of pauwels type-III femoral neck fractures.Most patients (85.7%) achieved good or excellent results with the use of PSTCS,which appears to be a reliable method and provides another choice for this problematic fracture.The new internal fixation method of PSTCS can provide mechanical stability and promote fracture healing

Introduction: Femoral neck fractures are one of the most common fractures primarily the elderly, coupled with a high degree of morbidity and mortality. The treatment is applied a number of methods of internal fixation (multiple cannulated screws available, DHS system, cefalomedullary). At the Department of Orthopedics and Traumatology of Nis developed a new method of fixation of femoral neck fracture, which allows stable fixation of dislocated and nondislocated femoral neck fracture. Self-tapping antirotation fixation (SAF) using two cannulated screws to initial compression fractures intraoperative and postoperative dynamic linear compression of the fracture with early full support to the patient. Matherial and methods: In the period between 2008 to 2012, 53 patients treated for femoral neck fracture in the Clinic for orthopedic and traumatology, Clinical center in Nis, Serbia, by SAF (the self-tapping cannulated screws antirotation; ORTOKON doo Nis). All patients were followed up after surgery in a minimum period of 13 weeks (13-106 weeks). The outcome was evaluated on the basis of clinical and radiological signs of fracture healing and the Harris hip score of functional recovery of the patient. Results: Of the total number of patients (53) treated with this method of fixation, 31 of them were females and 22 males, mean age 52.7 years (28-75 years). The average time of surgery was 36.4 minutes (19-70 minutes). During the postoperative follow-up of all patients (53) operated by this method, six patients were lost in the further postoperative monitoring, so that 47 patients remained for final evaluation. The total incidence of nonunion of femoral neck fracture after surgery this method was 6.4% (three patients). Shortening of the femoral neck after fixation by this method was recorded in 27 cases, and what amounted to an average of 2.8 mm (1, 2 mm in nondislocated to 4.55 with dislocated fracture) and did not affect the functional outcome. During radiographic follow-up was not detected fracture implants. Conclusion: Self-tapping screws cannulated antirotacioni (SAF method) represent a reliable method of fixation of dislocated and nondislocated femoral neck fracture. The main prerequisite for the proper healing of femoral neck fractures with this method is that anatomical fracture reduction is achieved by a closed or open method. This way of fixation allows the early full weight bearing patient operated limb and faster postoperative functional recovery of the fracture healing in optimal time.

Abstract Background: The purpose of this study was to compare the effectiveness of multiple cannulated screws combined with medial buttress plate or not for the treatment of unstable femoral neck fracture.Methods: 69 nonelderly patients with Garden type III-IV femoral neck fracture were retrospectively analyzed. The patients were divided into MCS (multiple cannulated screws) group and CMBP (combined with medial buttress plate) group according to the surgical method. Patient’s demographic data, Harris Hip Score, EQ-5D index and complications at minimum of 2 years follow-up were analyzed.Results: There were 47 patients in the MCS group (35 male and 12 females) with a mean age of 40.28±12.64 years, whereas 22 patients in the CMBP group (17 male and 5 females) with a mean age of 43.86±12.55 years. In the MCS group, there were one avascular necrosis, five postoperative nonunion, five implant failure, and two femoral neck shortening. While one implant failure, two postoperative nonunion and two impingement in the CMBP group. The difference of HHS scores was statistically significant at 3 months after surgery between the two groups (P<0.05), whereas there was no statistical significance at 6 months, 1 year and 2 years (P>0.05). The same results were found in EQ-5D index.Conclusions: Anatomic reduction and stable fixation contribute to satisfactory outcomes in the treatment of nonelderly displaced femoral neck fractures. A buttress plate in the medial region of the femur neck with cannulated screws offers patients the best biomechanical microenvironment needed for fracture healing without obviously blood-supply disruption, especially in Pauwels type Ⅱ and III.

Abstract Objective To compare the effects between computer-assisted and traditional cannulated screw internal fixation on treating femoral neck fracture. Methods The search was conducted in Embase, Pubmed, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wanfang Database from the beginning to August 2020. RevMan5.4 software, which was provided by the International Cochrane Group, was used for the meta-analysis comparing the differences in operation time, intraoperative bleeding volume, fluoroscopy frequency, fracture healing time, total drilling times, Harris score, fracture healing rate, and femoral head necrosis rate between computer-assisted and traditional methods groups. Results A total of 1028 patients were included in 16 studies. Primary outcome indicators: Compared with the traditional method group, the computer-assisted group had less operative time (2RCTs, P < 0.00001; 8 non-RCTs, P = 0.009; Overall, P < 0.00001), intraoperative bleeding (1 RCTs, P < 0.00001; 9non-RCTs, P < 0.00001; Overall, P < 0.00001), femoral head necrosis rate (1 RCT, P = 0.11;7 non-RCTs, P = 0.09; Overall, P = 0.02) and higher Harris scores (1 RCT, P < 0.0001; 9 non-RCTs, P = 0.0002; Overall, P < 0.0001), and there were no significant differences in fracture healing rate between the two groups (5 non-RCTs, P = 0.17). Secondary outcomes indicators: The computer-assisted group had a lower frequency of intraoperative fluoroscopy and total number of drills compared with the traditional method group, while there was no significant difference in fracture healing time. Conclusion Compared with the traditional hollow screw internal fixation on the treatment of femoral neck fracture, computer-assisted percutaneous cannulated screw fixation can shorten the operation time and improve the operation efficiency and reduce the X-ray injury of medical staff and help patients obtain a better prognosis. Therefore, computer-assisted percutaneous cannulated screw fixation is a better choice for the treatment of femoral neck fracture. Study registration PROSPERO registration number CRD42020214493.

Abstract Background This retrospective analysis compared the long-term outcomes for patients with a femoral neck fracture (AO/OTA type 31B) treated with a primary unilateral total hip arthroplasty with uncemented or cemented femoral components (UTHA or CTHA, respectively). Methods We conducted a retrospective cohort study using the South China Hip Arthroplasty Database. We identified 422 patients with femoral neck fracture (AO/OTA type 31B) who were previously treated with primary unilateral UTHA or CTHA between 2007 and 2015, with follow-up until 2019. Follow-up occurred 1, 3, 6 and 12 months postoperatively and yearly thereafter. The primary outcome was the Harris hip score (HHS). The secondary outcome was the orthopaedic complication rate. Results In total, 324 patients (UTHA n = 160, mean age 68.61 ± 7.49 years; CTHA n = 164, mean age 68.75 ± 7.04 years) were evaluated for study eligibility. The median follow-up was 73.3 months (range, 11.6–89.2 months). At the final follow-up, HHS was 74.09 ± 6.23 vs 79.01 ± 10.21 (UTHA vs CTHA, p = 0.012). Significant differences were detected in the incidence of prosthetic revision, loosening, and periprosthetic fracture between the UTHA and CTHA groups (7.5% for UTHA vs 1.8% for CTHA, p = 0.015; 17.5% for UTHA vs 8.5% for CTHA, p = 0.016; 11.9% for UTHA vs 4.9% for CTHA, p = 0.021, respectively). Conclusion In this setting, CTHA demonstrated superiority to UTHA by improving functional outcomes and decreasing complication rates.

Neck Fracture

A csípőtáji törésekhez idős korban magas halálozás társul. A szakirodalomban kevés a nagy beteganyagot feldolgozó, országos kiterjedésű ellátórendszer adatain alapuló feldolgozás. Célkitűzés: A tanulmány célja a 60 év feletti akut, monotraumás combnyaktöröttek primer ellátását követő halálozások vizsgálata havonta és évente ötéves utánkövetéssel, valamint a különböző rizikófaktoraik halálozásra gyakorolt hatásainak értékelése az egyes időperiódusokban. Módszer: Az adatok az Országos Egészségbiztosítási Pénztár adatbázisából származnak. Az értékelés bázisát a fekvőbeteg-ellátást végző intézményekből combnyaktörés primer műtéti ellátását követően 2000. évben emittált betegek képezik. Bemutatjuk az átlagos évenkénti, havonkénti és heti halálozási arányokat, valamint rizikótényezők szerinti alakulásukat havonként és évenként. A rizikótényezők és a halálozás kapcsolatának értékelése logisztikus és Cox-regressziós analízissel történik. Eredmények: A tanulmányban 3783 fő került elemzésre. Átlagéletkoruk 77,97 (SD 8,52) év. A halálozás az első héten 1,71%, 30 napon belül 8,99%, az első évben 30,74%, öt év alatt 61,88% volt. A halálozás havi szinten az első 5 hónapig mutat csökkenést, éves szinten az első év után stagnál. A rizikófaktorok közül a férfinem és a magasabb életkor öt évig, a kísérőbetegségek hatásai a negyedik évig, a laterális combnyaktöréstípus és a 12 órán túli ellátás két évig, a korai lokális szövődmények egy évig, a hétvégi ellátások az első hónapban eredményeznek magasabb halálozási kockázatot. Az országos és egyetemi ellátásokat követően az első évben alacsonyabb a halálozási kockázat. Következtetések: A csípőtáji törések managementjében a halálozások csökkentése érdekében hangsúlyozzuk a 12 órán belüli ellátás, a törési típusnak megfelelő módszerválasztás, a hét minden napján történő azonos ellátási feltételek biztosítása, az ellátások centrumokba történő szervezése, a beteg általános állapotának és kísérőbetegségeinek megfelelő akut ellátás és az utókezelések fontosságát.
