STUDY OF SUPRACONDYLAR FEMUR FRACTURE MANAGED SURGICALLY USING LOCKING COMPRESSION PLATE.

Background- Fractures of distal femur are one of the most prevalent fractures encountered in high-velocity trauma which are associated with high morbidity and mortality if not managed well. The isolated fracture can itself lead to complications such as Acute Respiratory Distress and pulmonary embolism. This neccesitaties early stabilisation of the fractures. Open reduction and internal fixation (ORIF) with locking compression plate is the treatment of choice for closed fractures of the distal femur. Distal femur anatomic contoured locking compression plate (LCP) has shown to give one of the best results regarding recovery, fracture union, return to work and the functional outcome. We present our experience of management of distal femur fracture at our centre. Study Material and Methodsdone on 36 patients, (NEER'S Classification) age range of 18 to 70 years (irrespective of their sex), were subjected to fixation by locking compression plate after obtaining thorough written informed consent. The observational study was carried at our institute between June 2021 to June 2022 Patients of both gender who were skeletally mature are taken into the study. In 61.5% of patients up to 50 years old and in Results40% of patients older than 50 years, the functional evaluation of LCP using Neers criteria was excellent. There was no statistically significant (p>0.05) difference in patients' functional status according to their age group who had distal femur fractures, which were stabilise by LCP. For supracondylar femur fractures, locking compression plates is a safe technique that has a good functional outcome, early clinical and radiographic union, and few complications.

Peri-implant femoral fractures: Challenges, outcomes, and proposal of a treatment algorithm / 中华创伤杂志(英文版)

PURPOSE@#Non-prosthetic peri-implant fractures are challenging injuries. Multiple factors must be carefully evaluated for an adequate therapeutic strategy, such as the state of bone healing, the type of implant, the time and performed personnel of previous surgery, and the stability of fixation. The aim of this study is to propose a rationale for the treatment.@*METHODS@#The peri-implant femoral fractures (PIFFs) system, a therapeutic algorithm was developed for the management of all patients presenting a subtype A PIFF, based on the type of the original implant (extra- vs. intra-medullary), implant length and fracture location. The adequacy and reliability of the proposed algorithm and the fracture healing process were assessed at the last clinical follow-up using the Parker mobility score and radiological assessment, respectively. In addition, all complications were noticed. Continuous variables were expressed as mean and standard deviation, or median and range according to their distribution. Categorical variables were expressed as frequency and percentages.@*RESULTS@#This is a retrospective case series of 33 PIFFs, and the mean post-operative Parker mobility score was (5.60 ± 2.54) points. Five patients (15.1%) achieved complete mobility without aids (9 points) and 1 (3.0%) patient was not able to walk. Two other patients (6.1%) were non-ambulatory prior to PPIF. The mean follow-up was (21.51 ± 9.12) months (range 6 - 48 months). There were 7 (21.2%) complications equally distributed between patients managed either with nailing or plating. There were no cases of nonunion or mechanical failure of the original implant.@*CONCLUSION@#The proposed treatment algorithm shows adequate, reliable and straightforward to assist the orthopaedic trauma surgeon on the difficult decision-making process regarding the management of PIFF occurring in previously healed fractures. In addition, it may become a useful tool to optimize the use of the classification, thus potentially improving the outcomes and minimizing complications.

Periprosthetic Femur Fracture in a 73-Year-Old Female: A Case Report

Increasing use of joint replacement for various conditions has led to a new group of fractures- the periprosthetic fractures. Periprosthetic fractures are considered which are associated with an orthopaedic implant. Worldwide incidence of Periprosthetic fractures is increasing due to increased number of primary joint arthroplasties and other revision surgeries. Periprosthetic femoral fracture can be classified as intraoperative & post-operative. The intraoperative periprosthetic fractures usually occur during the insertion of the femoral stem, often preceded by an area of increased cortical thickness. The management of these fractures are complex and usually needs application of basic principles to fit an individual situation rather than having a fixed set of rules. Standard treatment protocol includes use of locking plate with encirclage wires. In this study, we provide a case of periprosthetic femur fracture pain. A 75-year-old woman presented to us with pain in her right hip and thigh. The patient was a homemaker who had cemented total hip replacement surgery due to a femoral neck fracture 27 days back. After the primary replacement surgery, the patient appeared to be doing well and adhering to the hip precautions. While getting out of bed, she tripped and fell carelessly in the morning & complained of severe pain in her right hip. After assessment of all her medical conditions and physical examination, she was advised for revision surgery. An open reduction and internal fixation of the fracture with revision of the femoral component was planned. Risks, benefits, and alternatives were discussed at length with her and her family. The patient and her family agreed to the operative plan.

Predicting the Anatomical Location of Neck of Femur Fractures in Osteoporotic Geriatric Indian Population

@#Introduction: Neck of femur fractures are quite common fractures in the elderly. Though a lot is spoken about the various modes of management of these fractures across different age groups, hardly any literary support mentioning their distribution, location and pattern can be found. In this study, we aim to find whether the Singh index, as a marker of osteoporosis on digital radiographs, can predict the location of neck of femur fractures in the elderly population. Materials and methods: We accessed 556 fractured hip radiographs in our institution over the past 5 years (2015- 2020) and correlated with the Singh index, as a marker of degree of osteoporosis, on pre-operative pelvis digital radiographs. Mid coronal CT cuts were also corroborated with the radiographic findings. A control group was set up and 361 radiographs were evaluated in the study group. Results: A total of 124 transcervical fractures (73%) were in Singh index 4, while 76 subcapital fractures (70%) were in Singh index 3. A total of 166 fractures (66%) were found in transcervical region in the age group of 60 to 80 years, while 80 fractures (74%) were in the subcapital region in patients above 80 years. Conclusion: We concluded that transcervical fractures were more common in patients with Singh index 4 (p<0.001) and subcapital more common in patients with Singh index 3(p<0.001). There was also a shift in location of the fractures from the transcervical region to the subcapital region with age above 80 years (p<0.001).

Fractura de fémur proximal (31-A3. 2) asociada al uso de tenofovir en paciente VIH+: reporte de caso / Proximal femur fracture (31-A3. 2) associated with the use of tenofovir in an HIV-positive patient: case report

Presentamos el primer reporte de caso en paciente adulto con virus de la inmunodeficiencia humana (VIH + ) con fractura por fragilidad en fémur proximal asociada al uso de terapia antirretroviral (TARV) con fumarato de disoproxilo de tenofovir (FDT) en Chile. Actualmente, los pacientes diagnosticados con VIH inician tratamiento precoz con TARV, lo que implica mayor cantidad de años de exposición a los fármacos de la terapia. El tiempo de exposición acumulado al FDT se ha asociado a disminución de la densidad mineral ósea y falla renal progresiva, pudiendo el paciente desarrollar síndrome de Fanconi adquirido y osteomalacia, con riesgo aumentado de fractura. Presentamos el caso de un hombre de 44 años, VIH+ , evaluado en urgencia tras caída a nivel que resultó en fractura patológica del fémur proximal. Los exámenes de ingreso destacaron hipocalemia, hipocalcemia, hipofosfatemia e hipovitaminosis D. Se realizó manejo multidisciplinario, con suspensión del FDT, un cambio en la TARV, y suplementación con calcio y carga de vitamina D. Se realizó reducción cerrada y fijación con clavo cefalomedular largo, que evolucionó favorablemente con rehabilitación motora precoz; el paciente recuperó su funcionalidad previa, y se observó consolidación ósea a las 12 semanas. La aparición de dolor osteomuscular en pacientes VIH+ en TARV debe levantar alta sospecha clínica de efecto adverso a medicamento; el seguimiento de estos pacientes debe incluir el control seriado de la función renal y de los niveles séricos de calcio y fósforo. La búsqueda y sospecha de estas complicaciones permitiría una intervención precoz, mejorando la condición de los pacientes y previniendo fracturas patológicas.

We present the first case report of a human immunodeficiency virus (HIV)-positive adult patient with a fragility fracture of the proximal femur associated with antiretroviral therapy (ART) with tenofovir disoproxil fumarate (TDF) in Chile. Currently, patients diagnosed with HIV start ART early, resulting in more years of exposure to these drugs. The accumulated exposure time to TDF has been associated with a decreased bone mineral density and progressive renal failure, potentially leading to acquired Fanconi syndrome, osteomalacia, and an increased risk of fracture. We present a case of a 44-year-old, HIV-positive man assessed at the emergency room after a fall from standing height which resulted in a proximal femoral pathological fracture. Laboratory findings at admission revealed hypokalemia, hypocalcemia, hypophosphatemia, and hypovitaminosis D. Multidisciplinary management was performed, with TDF discontinuation, ART change, and supplementation with calcium and vitamin D. Closed reduction and fixation with a long cephalomedullary nail was successful, with early motor rehabilitation, functional recovery, and bone consolidation at 12 weeks. Musculoskeletal pain in HIV-positive patients on ART must raise the clinical suspicion of an adverse drug effect; the follow-up of these subjects must include serial monitoring of renal function and serum calcium and phosphorus levels. Screening and suspicion of such complications would enable an early intervention, improving the patients' condition and preventing pathological fractures.

Clavo Intramedular de Sign en Rodilla Flotante: Una serie de casos / Sign Intramedullary Nail in 'Floating Knee". A Case Series Report.

INTRODUCCIÓN: El concepto de "rodilla flotante" describe fracturas ipsilaterales del fémur y la tibia, donde la rodilla está desconectada del resto de la extremidad. El mecanismo suele ser un trauma de alta energía. Las tasas de infección, no unión, malunión y rigidez de la rodilla, pérdida excesiva de sangre, embolia grasa, son relativamente altas; lo que lleva a un deterioro funcional y con frecuencia resultados no satisfactorios. La reducción definitiva inmediata y fijación de las fracturas por clavo intramedular disminuye la incidencia de complicaciones. MATERIALES Y MÉTODOS: Se realizó un estudio descriptivo, serie de casos de 7 pacientes tratados con el Clavo Intramedular de SIGN (Surgical Implant Generation Network); para establecer resultados funcionales, lesiones concomitantes, complicaciones y ventajas del clavo en nuestra práctica. RESULTADOS: La mayoría de pacientes fueron del sexo masculino, con una media de 26 años de edad. Todas las lesiones fueron producidas en accidentes de tráfico, el 50% de las fracturas fueron expuestas. Según la clasificacion de Blake & McBryde, 6 fueron de Tipo I y un caso tipo IIa. Los resultados funcionales se evaluaron según los criterios de Karlström&Olerud; excelentes y buenos resultados se obtuvieron en el 85% de los casos. Todas las fracturas consolidaron; se describe un caso de infección superficial y un paciente presentó acortamiento de miembro <3cms y limitación menor del rango de movilidad de la rodilla. CONCLUSIÓN: El CIM de SIGN resultó eficiente y versátil en el tratamiento de rodilla flotante en adultos. Con buenos resultados funcionales (85%) y baja incidencia de complicaciones.

BACKGROUND: "Floating knee" describes ipsilateral fractures of the femur and tibia, where the knee is disconnected from the rest of the limb. The mechanism is usually a high-energy trauma. Rates of infection, lack of union, stiffness of the knee, excessive blood loss, fat embolism, are relatively high; leading to functional impairment and often unsatisfactory results. Immediate definitive reduction and fixation of fractures by intramedullary nail reduces the incidence of complications. METHODS: A descriptive study was carried out, a case series report of 7 patientes treated by the SIGN Intramedullary Nail (IMN); to establish the functional results, concomitant injuries, complications and advantages of this nail, in our practice. RESULTS: The majority of the patients were male, with a mean age of 26 years. All injuries were caused in traffic accidents, 50% of the fractures were exposed fractures. According to the Blake & McBryde classification, 6 were Type I and one case Type IIa. Functional results were evaluated according to the Karlström and Olerud criteria; excellent and good results were obtained in 85% of cases. All of the fractures healed; one case of superficial infection was described, one patient presented limb shortening <3 cm and minor limitation of the knee motion range. CONCLUSION: The SIGN intramedullary nail, was efficient and versatile for the treatment of floating knee in adults. It had good functional results (85%) and low incidence of complications.

Comparison between the results of bipolar hemiarthroplasty with lateral approach and posterior approach in Sanglah General Hospital in 2018: a case series

The purpose of this study was to compare the preoperative, intraoperative and postoperative parameters of Bipolar Hemiarthroplasty procedure using lateral approach and posterior approach in Sanglah General Hospital in 2018. Thirty-five patients diagnosed with femoral neck fracture or intertrochanter fracture underwent Bipolar Hemiarthroplasty using either lateral approach or posterior approach at our institution between January 2018 and December 2018. The primary outcome measures were postoperative complication and hip function. The secondary outcome measures were surgical time, transfusion rate, length of hospital stay, intraoperative blood loss and postoperative haemoglobin. There were 14 patients in Lateral Approach group and 21 patients Posterior Approach group included for analysis. There were no significant differences between the two groups regarding to the Harris Hip Score at 6 months follow up. Significant differences were found between Bipolar Hemiarthroplasty with Lateral Approach and Bipolar Hemiarthroplasty with Posterior Approach group in comparison of intraoperative blood loss (p<0.05) and length of stay (p<0.05). The present study concluded that both lateral and posterior approaches are comparable in terms of functional outcomes and complications. However, there is a tendency of longer hospital of length of stay and more of intraoperative blood loss using posterior approach which should be kept in mind when orthopaedic surgeon is performing a bipolar hemiarthroplasty.

Comparative Study Regarding Functional and Radiological Outcomes of Different Modes of Fixation for Distal Femur Fracture.

Treatment of distal femur fractures has recently evolved towards indirect reduction and minimally invasive techniques. The goal is to strike a balance between the mechanical stability of the fragments and the biological viability. Advent of MIPO technique has reduced the amount of soft tissue injury, delayed healing, tissue necrosis and infections. The objective was to compare the functional and radiological outcome of fracture distal femur treated by open reduction with LCP by minimally invasive plate osteosynthesis (MIPO). We wanted to compare the clinical and radiological differences between open and MIPO techniques for distal femoral fracture fixation.METHODSThis was a prospective interventional study. 41 subjects with closed supracondylar femur fracture treated surgically from March 2013 to December 2017, were evaluated prospectively for functional and radiological outcome results after fixation with distal femoral locking compression plate in open or minimally invasive way, with minimum follow up of 1 year. IBM SPSS Ver. 25 software was used to perform statistical analysis.RESULTSThe mean age of 41 treated patients was 53.8 ± 13.7 years and ranged from 23 to 84 years. 19 patients were females and 22 were males. Mean time to surgery was 5.7 ± 2.9 days with minimum 2 and maximum of 18 days from injury. Initially 20 patients underwent open surgery and 21 patients were operated by minimally invasive plating technique. In all cases, a 316L stainless steel alloy distal femoral locking plate was used.CONCLUSIONSKnee ROM could be started at a mean of 1.4 weeks earlier in the MIPO group and this was statistically significant. The two groups did not differ significantly in start of full weight bearing. Knee flexion at 6 weeks was also comparable in the two groups. However, knee flexion was average 21.9° higher in MIPO group at 1 year which was significantly different than ORIF group. The proportion of patients with >90° and >110° knee flexion also varied significantly between the groups. VAS score in MIPO group was significantly less at 6 weeks but difference was non-significant at 1 year. There were 2 cases with non-union and implant failure in the ORIF group, but the proportion was not significant. There was 10° FFD in 1 patient of ORIF group, while varus deformity occurred in 3 patients of MIPO group. The proportion of deformity was not significantly different between the two groups.

Use of a morcellized fragment of bone as a bone graft in a femoral fracture repair / Uso de fragmento ósseo morcelizado como enxerto ósseo no reparo de fratura femoral

As one of the most frequent reasons for presentation at the orthopedic services in veterinary practice, long bone fractures need bone continuity for consolidation to take place. This case report has demonstrates the use of a morcellized fragment of bone as a bone graft in a femoral fracture with major bone loss. A mixed-breed adult cat with a segmental femoral fracture with a large longitudinal fissure in the central bone fragment was submitted to an interlocking nail osteosynthesis. During the procedure a fracture occurred along the fissure resulting in two bone fragments with significant bone loss. Fragments were morcellized and applied over the defect to act as a bone graft. By the 15th day after the surgery, the cat had a normal gait and showed no pain response, and bone consolidation occurred after 7 months. Once harvesting of humeral, femoral and tibial bone grafts can be frustrating in cats, resulting in just small amounts of bone, the morcellation of the central fragments was vital to provide sufficient graft to cover the big defect in the femoral shaft. The authors suggest that autologous fresh morcellized cortical bone fragments can be an adjunct to the treatment of comminuted fractures in cats, as an alternative to more traditional repairs of comminuted fracture.

Fraturas de ossos longos necessitam de continuidade óssea para que a consolidação ocorra. Este relato de caso tem como objetivo demonstrar o uso de um fragmento ósseo morcelizado com a função de enxerto ósseo em uma fratura de fêmur com presença de uma grande falha óssea entre os fragmentos. Um gato adulto, sem raça definida, com uma fratura múltipla em fêmur com presença de uma fissura longitudinal no fragmento central foi submetido à osteossíntese com uso de haste bloqueada. Durante o processo, ocorreu uma fragmentação a partir da fissura, o que resultou na presença de dois fragmentos ósseos com uma grande porção de perda óssea entre os dois. Os fragmentos ósseos restantes do fragmento central foram morcelizados e aplicados no defeito para atuar com enxerto ósseo. Quinze dias após a cirurgia o paciente apresentou apoio normal e ausência de dor, e consolidação óssea ocorreu em 7 meses pós operatórios. Uma vez que a coleta de enxerto nos gatos resulta em pouca quantidade de osso, a morcelização do fragmento central foi vital para promover enxerto suficiente para cobrir o defeito ósseo. Os autores sugerem que o uso de enxerto cortical autólogo fresco morcelizado pode ser um adjuvante no tratamento de fraturas cominutivas em gatos, como um tratamento alternativo à terapia convencional.

Superficial Femoral Artery Thrombosis After Midshaft Femoral Fracture Fixation With an Intramedullary Nail: A Case Report

@#Intramedullary nailing is the preferred method of closed shaft fracture fixation of long bones. One of the most dreaded complications to occur following internal fixation of a lower limb fracture is pseudo- or false aneurysm which can lead to the loss of the limb due to acute ischemia. This diagnosis is made by contrast angiogram of the limb. Pointers to the diagnosis include absent distal limb pulsation as well as other signs of acute ischemia post trauma or surgery. We present a case of development of pseudo-aneurysm in an elderly patient following open reduction and internal fixation of a femoral fracture. This case report outlines a prompt multidisciplinary approach of management in a rare case of pseudoaneurysm post fixation of long bone.

Importance of preoperative guided ultrasound in patients with femoral fracture: case report / Importância da ultrassonografia direcionada no pré-operatório de pacientes com fratura de fêmur: relato de caso

Abstract Objective: The aim of this report is to represent the role of the use of bedside ultrasound by the anesthesiologist, offering an individualized approach to the specific condition of the patient, without unnecessary postponement of femur fracture surgical repair in the elderly. Case report: Female patient, 86 years old, hypertensive, victim of trochanteric fracture of the femur, taken to the operating room after being released by cardiology service. A bedside ultrasound exam allowed the identification of aortic stenosis, left ventricular hypertrophy, carotid stenosis, and signs of hypovolemia. From these findings, it was decided to use an ultrasound-guided block of the nerves femoral and lateral cutaneous of the thigh as an anesthetic technique. Conclusions: The use of ultrasound guidance by the anesthesiologist can provide relevant information for individualizing the anesthetic technique, without postponing the surgical intervention, which usually occurs when the patient is referred for complete examination by the specialist.

Resumo Objetivo: Exemplificar o papel do emprego da ultrassonografia à beira do leito pelo anestesiologista e oferecer uma abordagem individualizada para a condição específica do paciente, sem que haja postergação desnecessária de correções cirúrgicas de fraturas de fêmur em idosos. Relato do caso: Paciente feminina, 86 anos, hipertensa, vítima de fratura trocantérica de fêmur, levada ao bloco cirúrgico após liberação cardiológica. O exame ultrassonográfico à beira do leito possibilitou a identificação de estenose aórtica, hipertrofia ventricular esquerda, estenose de carótida e indícios de hipovolemia. A partir desses achados, decidiu-se pelo bloqueio nos nervos femoral e cutâneo lateral da coxa guiado pela ultrassonografia como técnica anestésica. Conclusão: O uso da ultrassonografia direcionada à beira do leito pelo anestesiologista pode fornecer informações relevantes para a individualização da técnica anestésica, sem que haja postergação da intervenção cirúrgica, a qual comumente ocorre quando o paciente é referenciado para exame completo pelo especialista.

Clinical Evaluation of Demineralized Bone Matrix Allograft in Femur Fracture in Dogs

Eight clinical cases of dogs having femur fracture, were divided into two groups, A and B with four dogs (n=4) in each group. Group A animals were treated with intramedullary pinning (IMP) alone and group B were treated using IMP alongwith demineralized bone matrix (DBM) implantation at the fracture site. The efficacy of healing was evaluated on the basis of clinical evaluation, haemato-biochemical and radiographic parameters on the day of admission (day 0), followed by 7th, 15th, 30th, 45th and 60th post-operative days. The weight bearing was observed to be better in dogs of group A. Swelling was completely absent after 15th post-operative day in dogs of both the groups. The mean values of Hb, PCV, TLC and DLC showed a non-significant variation on subsequent post-operative days in both the groups. There was a significant increase in serum calcium up to 30th post-operative day and thereafter, followed a decreasing trend. The serum alkaline phosphatase values showed non-significant variation in group A while in group B animals significant increase observed on 15th, 30th and 45th post-operative day. Radiographically, the dogs of group B showed better radiographic union of fracture evidenced by early disappearance of fracture line than those of group A

Pantrochanteric Fracture: Incidence of the Complication in Patients with Trochanteric Fracture Treated with Dynamic Hip Screw in a Hospital of Southern Brazil / Fratura pantrocantérica: incidência da complicação em pacientes comfratura trocantérica tratados comparafuso dinâmico de quadril em um hospital do Sul do Brasil

Abstract Objective The aim of the present study was to investigate the incidence of pantrochanteric fractures in cases of trochanteric fractures treated with dynamic hip screw in our service. Methods A sample of 54 patients with trochanteric fractures treated with dynamic hip screws was included in this retrospective study. Preoperative radiographs were evaluated for fracture classification using the Arbeitsgemeinschaft für Osteosynthesefragen (Association for the Study of Internal Fixation, in German)/Orthopedic Trauma Association (AO/OTA) system for the identification of radiographic osteoporosis and for the measurement of the lateral femoral wall thickness. In the immediate postoperative images, the presence of pantrochanteric fracture was evaluated. Results The final sample presented an incidence of 16.7% of pantrochanteric fractures. The thickness of the lateral wall was significantly lower in the group with the complication (p < 0.001). Although fractures classified as 31-A2 were more numerous in the group with pantrochanteric fracture, the difference was not statistically significant (p = 0.456). Conclusion The percentage of pantrochanteric fractures in this service is in accordance with previous studies. There was an association between lateral femoral wall thickness and the occurrence of iatrogenic fracture of the lateral cortex. There was no significant difference between fracture classification and pantrochanteric fracture, possibly due to sample size.

Resumo Objetivo Investigar a incidência de fraturas pantrocantéricas nos casos de fraturas trocantéricas tratadas com parafuso dinâmico de quadril em nosso serviço. Métodos Uma amostra de 54 pacientes comfraturas trocantéricas tratadas comparafuso dinâmico dequadril foi incluída neste estudo retrospectivo. Foramavaliadas radiografias précirúrgicas para classificação das fraturas com o sistema AO/OTA, identificação de osteoporose radiográfica emensuração da espessura da cortical lateral, enquanto nas imagens pósoperatórias imediatas foi avaliada a presença de fratura pantrocantérica. Resultados Aamostrafinal apresentou a incidência de 16,7%defraturaspantrocantéricas. A espessura da parede lateral foi significativamentemais baixa no grupo coma complicação (p < 0,001). Embora a incidência de fraturas classificadas como 31.A2 tenha sido maior no grupo com fratura pantrocantérica, a diferença não foi significativa (p = 0,456). Conclusão O percentual de fraturas pantrocantéricas nesse serviço encontra-se em acordo com trabalhos prévios. Houve associação entre espessura da cortical lateral e ocorrência de fratura iatrogênica da parede lateral. Não houve diferença significativa entre classificação das fraturas e fratura pantrocantérica, possivelmente devido ao tamanho da amostra.

Tratamiento de fractura subtrocantérica multifragmentaria de alta energía en niño mediante osteosíntesis con placa de reconstrucción. Reporte de caso / Treatment of a high-energy multifragmentary subtrochanteric fracture in a child using osteosynthesis with a reconstruction plate. Case report

El objetivo del estudio es dar a conocer el uso del método de osteosíntesis mediante placa de reconstrucción moldeada para tratar fracturas subtrocantéricas pediátricas. Se trató a un paciente pediátrico de 7años de edad con el diagnóstico de fractura subtrocantérica de trazo multifragmentario producto de un trauma de alta energía. Fue intervenido mediante osteosíntesis con una placa 4,5 convencional moldeada colocada mediante técnica mínimamente invasiva. El modelo de la fijación derivó del propuesto por Moustafa. Se realizó planificación preoperatoria, tratamiento quirúrgico y seguimiento clínico y radiológico por consulta externa cada 2semanas hasta apreciar consolidación clínica y radiológica. Además, se registró si existió o no dolor, acortamiento patológico, pérdida de reducción o aparición de alguna complicación. Se logró obtener consolidación clínica y radiológica completa al cabo de 6semanas, dolor mínimo, no existió acortamiento residual de la extremidad, no existió pérdida de reducción y tampoco se dieron complicaciones. El método propuesto podría llegar a ser la mejor alternativa para tratar este grupo específico de pacientes en los que el antecedente de la lesión por alta energía y la característica del trazo fracturario pueden derivar en resultados subóptimos con otras técnicas.

The aim of this study is to present the use of the osteosynthesis method using a moolded reconstruction plate to treat paediatric subtrochanteric fractures. The case concerns a 7year-old paediatric patient with the diagnosis of a multifragmented tracer subtrochanteric fracture resulting from a high-energy trauma. Osteosynthesis was performed using a conventional 4.5 moulded plate using minimally invasive surgery. The fixation model used was the one proposed by Moustafa. Pre-operative planning, surgical treatment, and clinical and radiological follow-up were performed in the outpatient clinics every 2weeks until clinical and radiological consolidation. In addition, it was recorded whether or not there was pain, pathological shortening, loss of reduction or appearance of complication. It has been possible to obtain complete medical and radiological attention after 6weeks, minimal pain, there was no residual shortening of the limb, there was no loss of reduction and no complications occurred. The method may be the best alternative to treat this specific group of patients in whom the antecedent of high energy injury and the characteristic of the fracture tract may result in suboptimal results with other techniques.

Evaluation of results of open distal femur fractures with primary fixation and antibiotic impregnated collagen / 中华创伤杂志(英文版)

Purpose:@#Distal femoral fracture is one of the most common lower limb injuries and accounts for less than 1% of all fractures. Open fracture takes 5%-10% of the all distal femoral fractures, which is at an increased risk of complications. There were limited studies which documented the outcomes of such cases. The present study aims to evaluate the outcome and complications in these fractures using primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement.@*Methods:@#This is a prospective study conducted in a tertiary care orthopaedic hospital in northern India. Thirty patients of open distal femoral fractures were managed by primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement. They were followed for minimum of six months. Patients were followed up monthly for first four months, at six months and one year after surgery. Clinical and radiological signs of healing, any complications, time to union, and functional outcome were assessed.@*Results:@#The mean age of patients was 44.33 years (range 20-82 years) with male predominance of 66.7%. According to Gustilo-Anderson classification, there were 5, 15 and 10 patients with open grade I, II and IIIA distal femoral fractures respectively. According to orthopaedic trauma association (OTA) classification, majority of patients in our study were of C3 type. The mean time to bony union was 5.6 months (range 4-9 months). Average postoperative knee range of motion (ROM) at the latest follow-up was 98° (range 70°-120°). Lysholm knee scoring scale showed excellent score in 11 patients, good in 9 patients, fair and poor in 5 patients each; however, there was no significant correlation with fracture pattern types (p < 0.05). Knee stiffness was the major complications encountered in the study. The knee ROM was <90° in 5 patients and 90°-120° in rest of the patients, while 1 patient had extensor lag of 10°. One patient had implant failure and lost to follow-up; 3 patients had deep infection.@*Conclusion:@#An approach of primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to early aggressive debridement in open distal femur fractures shows significant results in terms of functional and radiological outcomes with minimal complications.

Outcomes following Treatment of Geriatric Distal Femur Fractures with Analyzing Risk Factors for the Nonunion

PURPOSE: Many international journals have published studies on the results of distal femoral fractures in elderly people, but only a few studies have been conducted on the Korean population. The aim of this study was to determine the factors that are associated with the outcomes and prognosis of fixation of distal femur fractures using the minimally invasive plate osteosynthesis (MIPO) technique in elderly patients (age≥60) and to determine the risk factors related witht he occurrence of nonunion. MATERIALS AND METHODS: This study is a retrospective study. From January 2008 to June 2018, distal femur fracture (AO/OTA 33) patients who underwent surgical treatment (MIPO) were analyzed. A total of 52 patients were included in the study after removing 121 patients that met with the exclusion criteria. Medical records, including surgical records, were reviewed to evaluate the patients' underlying disease, bone mineral density, the number of days delayed from surgery, complications and mortality. In addition, follow-up radiographs were used to determine bone union, delayed union and nonunion. RESULTS: The average time to achieve bone union was 19.95 weeks, the rate of nonunion was 20.0% (10/50) and the overall mortality was 3.8% (2/52). There were no significant differences in the clinical and radiological results of those patients with or without periprosthetic fracture. On the univariate analysis, which compared the union group vs. the nonunion group, no factors were identified as significant risk factors for nonunion. On the multiple logistic regression analysis, medical history of cancer was identified as a significant risk factor for nonunion (p=0.045). CONCLUSION: The rate of nonunion is high in the Korean population of elderly people suffering from distal femur fracture, but the mortality rate appears to be low. A medical history of cancer is a significant risk factor for nonunion. Further prospective studies are required to determine other associated factors.

Interlocking Nailing in Comminuted Femoral Shaft Fractures: A Prospective Study in a tertiary care hospital

Background: Fracture shaft of femur is one of the most common fractures encountered in orthopaedic practice. Fracture shaft of femur is major cause of morbidity and mortality in patients who sustain high energy trauma. Methods: This prospective study was performed at Department of Orthopaedics, Varun Arjun Medical College, Banthra, Shahjahanpur, U.P, India. All patients aged 20 years or above, who presented with comminuted femur fracture and were treated with interlocking nailing was included in the study. Various clinical and radiological parameters were collected during the course of treatment. Results: N=30 patients were included in the study; 76% males. 88% aged 50 years or less. Road traffic accident was the most common mode of injury and 54% of patients had fracture in the middle one-third femur. 76% of the patients presented within 24 hours of injury. 52% of the patient’s demonstrated clinical union of the fracture in 12 to 14 weeks and majority showed radiological union in 16 to 18 weeks. Partial weight bearing was started in 38% patients in 10 weeks and full weight bearing in 48% patients  in  16 weeks. Majority of the patients stayed in hospital for 10 to 14 days and the functional outcome as measured by Klemm and Borner criteria was excellent in 69% patients. Conclusions: In our experience, interlocking nailing had very low complication rate and excellent functional outcome in two thirds patients of comminuted femur fracture.

Fracturas articulares de fémur distal. Análisis comparativo de tres tratamientos quirúrgicos / Articular fractures of the distal femur. Comparative analysis of three surgical treatments

Resumen: Introducción: La fractura articular de fémur distal es una lesión grave que durante años ha representado un problema en la traumatología que con frecuencia ocasiona distintos grados de incapacidad permanente en la rodilla. El destino de la articulación estaba determinado por la lesión más que por su tratamiento. Objetivos: Presentar los resultados del tratamiento quirúrgico de las fracturas articulares de fémur distal tipo C2 con tres modalidades de tratamiento: tornillo dinámico condíleo (TDC), placa de sostén condíleo (PSC) y placa periarticular (PPA). Material y métodos: Estudio comparativo de tres series terapéuticas, diseñado para comparar la efectividad del TDC, la PSC y la PPA en el tratamiento de fracturas articulares completas de fémur distal tipo C2. Se incluyeron 42 pacientes de ambos géneros, con edades entre 16 y 60 años, tratados en el IAHULA, con un seguimiento mínimo de 24 meses. Resultados: Predominó el sexo masculino con 73.8%, el grupo etario más afectado fue de 21-30 años con 28.57%. El tipo de fractura más frecuente fue la 33C2.3 con 42.86%. La PPA mostró mejores resultados que los otros implantes fundamentalmente en la escala funcional de la Knee Society. Setenta y uno punto cuarenta y tres por ciento de los pacientes presentó alguna complicación, resaltando la rigidez articular, la desviación angular en recurvatum, el dolor crónico y la artrosis postraumática. Conclusión: El TDC y la PPA son opciones válidas para el tratamiento de las fracturas de fémur distal AO 33C2, puesto que ofrecieron mejores resultados funcionales que la PSC

Abstract: Introduction: The distal articular femur fracture is a serious injury that for years has been a problem in traumatology. It is often believed that produced varying degrees of permanent disability in the knee and that the fate of the joint was determined by the injury rather than treatment. Objectives: Present the results of surgical treatment of articular distal femur fractures type C2 with three treatment modalities: dynamic condylar screw (TDC), condylar buttress plate (PSC) and periarticular plate (PPA). Material and methods: We conducted a comparative study of three therapeutic series designed to compare the effectiveness of dynamic condylar screw, the condylar buttress plate and periarticular plate in treating complete articular fractures of distal femur type C2. Patients of both genders, aged between 16 and 60 years, treated in the IAHULA, with a minimum follow up of 24 months. Results: We included 42 patients divided into three groups. Males predominated with 73.8%, the most affected age group was 21-30 years with 28.57%. The most common type of fracture was the 33C2.3 with 42.86%. The 71.43% of patients experienced complications, highlighting joint stiffness, angular deviation in recurvatum, chronic pain and post traumatic osteoarthritis. Conclusion: TDC and the PPA are valid options for the treatment of distal femur fractures AO 33C2, as offered better functional results than PSC.

Primary total hip arthroplasty versus hemiarthroplasty for displaced neck femur fractures in older patients

Background: Hip fractures in older patients are associated with impaired mobility, excess morbidity and mortality, and loss of independence. Objectives: To determine whether total hip arthroplasty is associated with lower reoperation rates, mortality, and complications, and better function and quality of life than hemiarthroplasty for displaced fractures of the femoral neck in older patients. Materials and methods: We prospectively as well as retrospectively studied 46 patients treated with total hip replacement or hemiarthroplasty. Pain, range of motion, hip function, haris hip score and complications were assessed clinically while hip stability, femoral anteversion, acetabular cup inclination and acetabular erosions were assessed radiographically. Results: In our study according to Harris hip score, group A (hemiarthroplasty group) showed 58.33% excellent to good result whereas 33.34% shows fair to poor result. In group B (total hip replacement group) 90.91% showed excellent to good result and 9.08% showed fair to poor result. In this study, the overall Harris hip score was 76.33 with SD±19.091 in hemiarthroplasty group and 86.45 with SD±6.363 in Total hip replacement group with p-value 0.0224(<0.05).
