Errores de osteosíntesis en fracturas laterales de cadera tratadas con placa/tornillo deslizante [Osteosynthesis pitfalls in lateral hip fractures treated with plate / sliding screw system].

Introducción: El uso de los sistemas placa/tornillo deslizante para fracturas intertrocantéricas ha demostrado ser un método de fijación eficaz, pero no está exento de fallas. El propósito de este estudio fue evaluar las causas de falla en los pacientes con fracturas laterales de cadera, tratados con placa/tornillo deslizante, puntualizando los defectos técnicos en la colocación.Materiales y Métodos: En nuestro centro, se trató a 177 pacientes por fractura lateral de cadera, a 151 de ellos se les practicó osteosíntesis con placa/tornillo deslizante. Se analizaron la adecuada reducción posoperatoria, la medición de la distancia punta a vértice, la posición del tornillo cefálico en la cabeza femoral y las posibles complicaciones.Resultados: La serie quedó conformada por 143 pacientes. El seguimiento promedio fue de 18 meses (rango 12-48). La tasa de fallas fue del 8,4% (n = 12): 7 (4,8%) por migración cefálica (cut-out) del tornillo proximal, 2 (1,4%) por migración medial (cut-through), 2 (1,4%) presentaron seudoartrosis y un caso (0,70%) de reducción inadecuada en varo. El porcentaje de una segunda operación fue del 7,7% (n = 11). La peor posición fue la superior/posterior con un 100% de migración (n = 4) (p <0,001, diferencia estadísticamente significativa).Conclusión: El posicionamiento superior/posterior del tornillo cefálico podría incrementar la posibilidad de migración y, en consecuencia, la tasa de falla del sistema. AbstractIntroduction: The use of Dynamic Hip/Sliding Screw (DHS) for intertrochanteric fractures has proven to be an effective fixation method, but it also has its failures.The purpose of this study was to evaluate the reason of failures in patients with lateral hip fractures that were treated with a DHS.Method:177 patients were treated in our center for lateral hip fracture. In 151 of them we used a DHS. The adequate postoperative reduction, the measurement of the tip-to-apex distance, the position of the cephalic screw in the femoral head and the possible complications were analyzed.Results: The series was made up of 143 patients. The average follow-up was 18 months (range 12-48). The failure rate was 8.4% (n = 12): 7 (4.8%) due to cephalic migration (cut-out) of the proximal screw, 2 (1.4%) due to medial migration (cut-through) , 2 (1.4%) presented pseudoarthrosis and one case (0.70%) of inadequate reduction in varus. The percentage of a second operation was 7.7% (n = 11). The worst position was the superior / posterior with 100% migration (n = 4) (p <0.001, statistically significant difference).Conclusion: The superior / posterior positioning of the head screw could increase the possibility of migration and, consequently, the failure rate of the system.

Aim: This study aimed to review the clinical findings and surgical intervention of the hip fracture at the Hue University Hospital in Vietnam. Methods:The data of proximal femoral fractures was collected retrospectively. All patients, in a period of 5 years, from Jan 2008 to December 2012, suffered either from intertrochanteric or femoral neck fractures. The numbers of patients were gathered separately for each year, by age groups (under 40, 40-49, 50-59, 60-69, 70-79, older) and by sex. We analyzed what kind of treatment options were used for the hip fracture. Results:Of 224 patients (93 men and 131 women) studied, 71% patients are over 70 years old, 103 women and 56 men (p<0.05). For patients under 40 years, there were 1 woman and 11 men (p<0.05). There were 88 intertrochanteric and 136 femoral neck fractures. There was no significant difference in the two fractures between men and women. The numbers of hip fracture increased by each year, 29/224 cases in 2010, 63/224 cases in 2011, 76/224 cases in 2012. Treatment of 88 intertrochanteric fractures: 49 cases (55.7%) of dynamic hip screw (DHS), 14 cases of hemiarthroplasty (15.9%), 2 cases of total hip replacement (2.3%). Treatment of 136 femoral neck fractures: 48 cases of total replacement (35.3%), 43 cases of hemiarthroplasty (31.6%), 15 cases of screwing (11%). In cases of 40 patients (17.9%) hip fracture was managed conservatively, 23 were femoral neck fractures and 17 were intertrochanteric fractures. Conclusions: Hip fracture is growing challenge in Hue medical university hospital. The conservative approach is still high in people who could not be operable due to severe medical conditions as well as for patients with economic difficulties. Over 70% of the hip fractures in people 70+ are caused by osteoporosis. The number of hip fracture is increasing in the following years, most likely due to the increase in the prevalence of osteoporosis. Early detection and prevention of osteoporosis should be addressed, particularly in high risk population. More aggressive surgical approach should be implemented in order to improve the quality of life in patients with hip fractures. Key words:Hip fracture.

Introduction: A novel virus, SARS-CoV-2, has caused a fatal global pandemic which particularly affects the elderly and those with comorbidities. Hip fractures affect elderly populations, necessitate hospital admissions and place this group at particular risk from COVID-19 infection. This study investigates the effect of COVID-19 infection on 30-day hip fracture mortality. Method: Data related to 75 adult hip fractures admitted to two units during March and April 2020 were reviewed. The mean age was 83.5 years (range 65–98 years), and most (53, 70.7%) were women. The primary outcome measure was 30-day mortality associated with COVID-19 infection. Results: The COVID-19 infection rate was 26.7% (20 patients), with a significant difference in the 30-day mortality rate in the COVID-19-positive group (10/20, 50%) compared to the COVID-19-negative group (4/55, 7.3%), with mean time to death of 19.8 days (95% confidence interval: 17.0–22.5). The mean time from admission to surgery was 43.1 h and 38.3 h, in COVID-19-positive and COVID-19-negative groups, respectively. All COVID-19-positive patients had shown symptoms of fever and cough, and all 10 cases who died were hypoxic. Seven (35%) cases had radiological lung findings consistent of viral pneumonitis which resulted in mortality (70% of mortality). 30% ( n = 6) contracted the COVID-19 infection in the community, and 70% ( n = 14) developed symptoms after hospital admission. Conclusion: Hip fractures associated with COVID-19 infection have a high 30-day mortality. COVID-19 testing and chest X-ray for patients presenting with hip fractures help in early planning of high-risk surgeries and allow counselling of the patients and family using realistic prognosis.

And Control

Background Femoral head collapse and coxa vara lead to internal fixator failure in elderly patients with hip fracture. External fixator application is an optimal choice; however, the existing methods have many disadvantages. Methods Type 31-A1.3 hip fracture models were developed in nine pairs of 1-year-old fresh bovine corpse femur specimens. Each left femur specimen was fixed by a dynamic hip screw (control group), and each right femur specimen was fixed by the slide-poking external fixator (experimental group). Vertical loading and torsion tests were then performed in both groups. Results In the vertical loading experiment, a 1000-N load was implemented. The mean vertical downward displacement of the femoral head in the experimental and control groups was 1.49322 ± 0.116280 and 2.13656 ± 0.166374 mm, respectively. In the torsion experiment, when the torsion was increased to 10.0 Nm, the mean torsion angle in the experimental and control groups was 7.9733° ± 1.65704° and 15.4889° ± 0.73228°, respectively. The slide-poking external fixator was significantly more resistant to compression and rotation than the dynamic hip screw. Conclusion The slide-poking external fixator for hip fractures that was designed and developed in this study can provide sufficient stability to resist compression and rotation in hip fractures.

Background: Limited evidence exists for meniscal repair outcomes in a multiligament reconstruction setting. Purpose/Hypothesis: The purpose of this study was to assess outcomes and failure rates of meniscal repair in patients who underwent multiligament reconstruction compared with patients who underwent multiligament reconstruction but lacked meniscal tears. The authors hypothesized that the outcomes of meniscal repair associated with concomitant multiligament reconstruction would significantly improve from preoperatively to postoperatively at a minimum of 2 years after the index surgery. Secondarily, they hypothesized that this cohort would demonstrate similar outcomes and failure rates compared with the cohort that did not have meniscal lesions at the time of multiligament reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: Inclusion criteria for the study included radiographically confirmed skeletally mature patients of at least 16 years of age who underwent multiligamentous reconstruction of the knee without previous ipsilateral osteotomy, intra-articular infections, or intra-articular fractures. Patients were included in the experimental group if they underwent inside-out meniscal suture repair with concurrent multiligament reconstruction. Those included in the control group (multiligament reconstruction without a meniscal tear) underwent multiligament reconstruction but did not undergo any type of meniscal surgery. Lysholm, Western Ontario and McMaster Universities Osteoarthritis Index, Short Form–12 physical component summary and mental component summary, Tegner activity scale, and patient satisfaction scores were recorded preoperatively and postoperatively. The failure of meniscal repair was defined as a retear of the meniscus that was confirmed arthroscopically. Results: There were 43 patients (16 female, 27 male) in the meniscal repair group and 62 patients (25 female, 37 male) in the control group. Follow-up was obtained in 93% of patients with a mean of 3.0 years (range, 2.0-4.7 years). There was a significant improvement between all preoperative and postoperative outcome scores ( P < .05) for both groups. The meniscal repair group had significantly lower preoperative Lysholm and Tegner scores ( P = .009 and P = .02, respectively). There were no significant differences between any other outcome scores preoperatively. The failure rate of the meniscal repair group was 2.7%, consisting of 1 symptomatic meniscal retear. There was no significant difference in any postoperative outcome score at a minimum 2-year follow-up between the 2 groups. Conclusion: Good to excellent patient-reported outcomes were reported for both groups with no significant differences in outcomes between the cohorts. Additionally, the failure rate for inside-out meniscal repair with concomitant multiligament reconstruction was low, regardless of meniscus laterality and tear characteristics. The use of multiple vertical mattress sutures and the biological augmentation resulting from intra-articular cruciate ligament reconstruction tunnel reaming may be partially responsible for the stability of the meniscal repair construct and thereby contribute to the overall improved outcomes and the low failure rate of meniscal repair, despite lower preoperative Lysholm and Tegner scores in the meniscal repair group.

Category: Bunion Introduction/Purpose: Kirschner-wires fixation, sometimes we have encountered pin irritation or pull-out. This is the reason why we consider additional fixation. Moreover, there are few reports according to comparison of fixation method, and Most of them focused on comparison K-wires or screw fixation only. Purpose of study is to compare clinical and radiographic outcome between Kirschner-wires only and combined screw fixation. Methods: The study included two different groups according to fixation methods. One with Kirschner-wires fixation (KW group) included 117 feet(of 98 patients), the other with combined screw fixation (KWS group) 56 feet (of 40 patients) with moderate to severe hallux valgus. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain scores, the preoperative and final follow-up American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal (MTP)-interphalangeal (IP) scores, and patient satisfaction after the surgery were evaluated. Radiographically, the hallux valgus angle (HVA), intermetatarsal angle (IMA), medial sesamoid position (MSP), and first to fifth metatarsal width (1-5MTW) were analyzed before and after surgery. Results: The mean AOFAS score improved preoperative 65.5 to 95.3 at final follow up in group A, while preoperative 56.5 to 88.6 at final follow up. Pain VAS decreased from 5.7 to 0.5 in group A, whereas from 6.2 to 1.6 in group B. The mean HVA all improved from preoperative 38.5 to 9.3 at final follow up in group A and 34.7 to 9.1 in group B. The mean IMA and MSP also improved significantly at final follow up. In comparative analysis, the IMA did not show significant difference between postoperative and final state in group A, while showed significant increase in group B. Conclusion: We achieved favorable clinical and radiographic outcomes with minimal complications in patient with moderate to severe hallux valgus in both groups. However, this study shows no statistically significant difference in IMA during follow-up period and lower recurrence rate. Therefore we need to consider combined fixation method to provide better stability and can expect lower recurrence rate.

Objective Our study aimed to assess the risk of all fractures and hip fractures in patients with atrial fibrillation (AF) who took non-vitamin K antagonist oral anticoagulants (NOACs) compared to warfarin. Methods We searched PubMed, Embase, and Cochrane Library and Clinical Trials.gov Website. Reviewed related researches up to January 31, 2020, to identify studies with more than 12 months of follow-up data. The protocol for this systematic review and meta-analysis has been registered in the International Prospective Register of Systematic Reviews (PROSPERO Number: CRD42020156893). Results We included five RCT studies, and five observational studies that contained a total of 326,846 patients in our meta-analysis. Our meta-analysis showed that patients taken NOACs had no significant all fracture risk (RR = 0.91, 95% CI [0.81–1.01]) and hip fracture risk (RR = 0.92, 95% CI [0.82–1.03]) compared with those taken warfarin. Subanalysis showed that the risk of all fractures and hip fractures treated by NOACs were significant lower compared with warfarin in observational studies compared with RCT studies. Also, a subanalysis across the duration of anticoagulation showed the NOACs users have lower all fracture risk than warfarin users when the duration of anticoagulation ≤2 years (RR = 0.89, 95% CI [0.80–0.99]). Further analysis, significant lower all fracture risk in the rivaroxaban therapy (RR = 0.81; 95% CI [0.76–0.86]) compared with warfarin but no statistical significance in hip fracture. There were no significant difference of all fracture risk and hip fracture risk in dabigatran, apixaban, and edoxaban therapy compared with warfarin. Conclusion The meta-analysis demonstrated that NOACs associated with a significantly lower all fracture risk compared with warfarin when the duration of anticoagulation more than 2 years. Rivaroxaban users had lower risk of all fracture than warfarin users in AF patients. But there was no evidence to verify apixaban, edoxaban, and dabigatranin could decrease all fracture and hip fracture risk compared with warfarin.

Introduction: A minority of patients with hip fractures sustain concomitant wrist fractures. Little is known about the rehabilitation outcome in this group of patients. Aim of study: Prospective investigation of functional outcome and survival in patients with combined hip and wrist fractures compared with patients who sustain an isolated hip fracture. Methods: 341 patients who presented with an acute hip fracture during a 12 month period were included in the study. Outcome at discharge and 4 months follow-up was compared between patients with isolated hip fractures and those patients who sustained simultaneous distal wrist fractures. Results: The actual incidence of concurrent hip and wrist fractures in our cohort was 4.7%. Patients who sustained a concurrent hip and wrist fracture showed no differences regarding short- and long-term functional outcome and survival. Conclusion: Our results imply that patients with simultaneous hip and wrist fractures have no difference in rehabilitative outcome. Future studies should further investigate the distinctive characteristics of this patient subgroup.

Abstract: Introduction: Although several national studies reported on the risk factors for contralateral hip fracture, there are no data about the prognostic factors of the time until contralateral hip fractures. Aim: The aim of the study was to analyse the impact of different prognostic factors on the time until the development of contralateral fracture and to determine the incidence of contralateral hip fractures after femoral neck fractures. Method: Patients aged 60 years and over with contralateral hip fracture between 01 Jan 2000 and 31 Dec 2008 were identified among those who suffered their femoral neck fracture in Hungary in 2000. Risk factors as age, sex, comorbidities, type of fracture and surgery, place of living and hospitals providing treatment for primary fracture were analysed by one way ANOVA focusing on the time until the development of contralateral hip fracture. Results: 312 patients met the inclusion criteria. The incidence of contralateral hip fracture after femoral neck fracture ranged between 1.5% and 2.1%, the cumulative incidence was 8.24%. The mean time until the development of contralateral hip fracture was 1159.8 days. The incidence of contralateral hip fracture showed no significant deviation. Significantly shorter time (p = 0.010) was detected until the contralateral hip fracture in older patients with femoral neck fracture. Conclusions: The yearly incidence of contralateral hip fracture showed no significant difference by patients with femoral neck fracture over 60 years. The shorter time until the contralateral hip fracture by the older age groups highlights the need of elaboration of prevention strategies. Orv Hetil. 2018; 159(38): 1543–1547.

AbstractMilk provides energy and nutrients considered protective for bone. Meta-analyses of cohort studies have found no clear association between milk drinking and risk of hip fracture, and results of recent studies are contradictory. We studied the association between milk drinking and hip fracture in Norway, which has a population characterised by high fracture incidence and a high Ca intake. Baseline data from two population-based cohorts were used: the third wave of the Norwegian Counties Study (1985–1988) and the Five Counties Study (2000–2002). Diet and lifestyle variables were self-reported through questionnaires. Height and weight were measured. Hip fractures were identified by linkage to hospital data with follow-up through 2013. Of the 35 114 participants in the Norwegian Counties Study, 1865 suffered a hip fracture during 613 018 person-years of follow-up. In multivariable Cox regression, hazard ratios (HR) per daily glass of milk were 0·97 (95 % CI 0·92, 1·03) in men and 1·02 (95 % CI 0·96, 1·07) in women. Of 23 259 participants in the Five Counties Study, 1466 suffered a hip fracture during 252 996 person-years of follow-up. HR for hip fractures per daily glass of milk in multivariable Cox regression was 0·99 (95 % CI 0·92, 1·07) in men and 1·02 (95 % CI 0·97, 1·08) in women. In conclusion, there was no overall association between milk intake and risk of hip fracture in Norwegian men and women.

Abstract Background: To investigate the treatment effect of minimally invasive treatment of early osteonecrosis of femoral head (ONFH) with hydroxyapatite coated hollow titanium rod. Methods: From 1, January 2003 to 1, January 2019, 72 patients with ONFHⅡ Stage were selected. There were 50 males and 20 females, aged from 28 to 56. Onset time was 8~28 months. Lesion site: 18 left, 38 right, 16 bilateral. Causes of ONFH: 30 alcohol, 28 hormone, 9 trauma and 5 idiopathic patients. ARCO stage: 14 IIA, 33 IIB, 25 IIC. All patients underwent arthroscopic assisted minimally invasive percutaneous core decompression and bone grafting with hydroxyapatite coated titanium rod surgery. Visua Analogue Scales (VAS), Harris score and Images were used for assessing pain, hip joint function and the stability, respectively. Hip replacement was performed finally. Results: 16 patients with heavy hormone use history and femoral head collapse underwent Total Hip Resurfacing Arthroplasty (THRA) at the last follow-up. 24 months later, 8 ⅡB cases progressed to ⅡC, 2 cases were stable at ⅡC, 6 cases increased to Ⅲ, and underwent THRA. 12ⅡC cases progressed to Ⅲ, 2 cases were stable at Ⅲ, and 10 cases had articular cartilage surface collapse. THRA was administered 30 months after surgery. VAS score of individual patients increased and Harris score decreased 24 months after surgery, but there was no significant difference between the scores of 12 months and 24 months. The clinical effect of the last follow-up showed that the postoperative improvement rate of this group was 76.13%, among which the best was 100% in IIA, 79.48% in IIB, and the lowest was 58.06 in IIC. Both the patients with IIB or IIC, cases with aggravation and without change were hormonal ONFH. Conclusion: The treatment of ONFH with hydroxyapatite coated hollow titanium rod supporting the femoral head to prevent collapse is feasible. In addition to the Glucocorticoid-induced ONFH stage ⅡC outside, this method to other Ⅱ period lesions in improving the curative effect and preventing the collapse of femoral head articular surface is good and safe.
