Predictors of the Outcome Destination of Patients with a Proximal Femoral Fracture in a Convalescent Rehabilitation Ward / The Japanese Journal of Rehabilitation Medicine

Purpose：This study aimed to clarify the conditions necessary for patients with a proximal femoral fracture in the convalescent ward to return home using a decision tree analysis. This study included 181 patients who were discharged from the convalescent ward between January 2018 and June 2022.Methods：Patients divided into two groups：home vs. facility according to the outcome. Basic characteristics, FIM at admission, and MMSE at admission were compared using the unpaired t-test, χ2 test, and Mann-Whitney U test, and a decision tree analysis was performed.Results：The decision tree analysis based on functional independence measures (FIM) on admission and toileting activities, etc. found that discharge was difficult (return home rate：9.7％-28.6％) when the problem-solving aspect of the FIM on admission was less than 4 points.Conclusion：When discharging patients with a proximal femoral fracture from the hospital, it is important to consider a combination of problem-solving in the admission FIM and toileting activities.

Regional CT value in prediction of proximal femoral fracture / 中国骨伤

OBJECTIVE@#To investigate CT values of cancellous bone in femoral neck in adults over 60 years with proximal femoral fractures.@*METHODS@#From January 2020 to December 2020, a retrospective analysis was performed on 280 subjects aged 60 years or older who underwent bilateral hip CT examination, including 85 males and 195 females, 120 on the left side and 160 on the right side, aged 75 (66, 82) years old. One hundred thirty-six patients with proximal femoral fractures were included in study group and 144 patients without fractures were included in control group. GEOptima CT was used to scan and reconstruct horizontal, coronal and sagittal layers of proximal femur. CT values of cancellous bone in femoral neck were measured and compared between two groups. The relationship between CT values of cancellous bone of femoral neck and proximal femoral fracture was analyzed statistically.@*RESULTS@#In terms of age, fracture group aged 79(73.3, 85.0) years old, non-fracture group aged 69.5 (64.0, 78.8) years old, and had significant difference in age between two groups (P<0.05). In terms of CT value, regional CT value in fracture group was 8.62(-3.62, 27.15) HU, which was lower than that in non-fracture group 34.31(-5.93, 71.74) HU(P<0.05). CT value on coronal view in fracture group was -8.48(-30.96, 17.46) HU, which was lower than that in non-fracture group 40.49(5.55, 80.71) HU (P<0.05). CT value on sagittal view in fracture group was -31.28(-54.91, -5.11) HU, which was lower than that in non-fracture group 7.74(-20.12, 44.54) HU (P<0.05). CT values on horizontal view in fracture group was 0.17(-23.13, 24.60) HU, which was lower than that in non-fracture group 46.40(10.42, 85.18) HU(P<0.05). The mean regional CT values among three planes in the fracture group were lower than those in the non-fracture group. Logistic regression analysis showed coronal CT value was influencing factors of proximal femoral fracture, and it could be written into regression equations that predict probability of fracture.@*CONCLUSION@#In adults aged over 60 years old, CT values of cancellous bone of femoral neck decreased with increasing age. The smaller CT value of cancellous bone of femoral neck, the greater risk of proximal femoral fracture.

Research of Building 3D Model in External Fixator for Proximal Femoral Fracture Based on Locking Plate Shape / 中国医疗器械杂志

The software of 3D-Modeling(UG NX 10.0) was used to design a new external fixator model for proximal femoral fracture, and fresh femoral cadaver specimens were used to simulate experimental operation. The results showed that the external fixator designed with the proximal femoral locking plate shape can improve the accuracy of Kirschner wire penetration into the femoral neck, reduce fluoroscopic and soft tissue incision injuries, and make a good stability and is easy to operate, which has a certain value for patients with proximal femoral fracture, such as intolerant surgery and poor physical condition.

Necrosis avascular: complicación en un paciente joven / Avascular Necrosis: Complication in a Young Patient

Resumen: La presentación de una fractura de fémur proximal es totalmente diferente en pacientes jóvenes que en pacientes adultos. A diferencia de la fractura cerrada de fémur proximal, la incidencia de fracturas expuestas se encuentra en la población joven de entre 15 y 30 años de edad. Dentro de las complicaciones que podemos observar en estas fracturas se encuentra la osteonecrosis avascular (NAV) de la cabeza femoral, la cual se define como la interrupción del aporte sanguíneo a la cabeza femoral, ya sea por trauma, infección, alcoholismo o uso de esteroides, ocasionando necrosis ósea, colapso articular y osteoartrosis. El tratamiento dependerá de la presentación del caso, la edad del paciente y el tiempo en hacer el diagnostico. Se presenta el caso clínico de un paciente de 16 años de edad el cual ingresa al servicio de urgencias con diagnóstico de herida por arma de fuego a nivel de cadera izquierda. Se realiza lavado quirúrgico y reducción cerrada más fijación interna con clavo centro medular. Se da un seguimiento clínico y radiográfico por 3 años observando la evolución de la fractura y la subsecuente necrosis avascular que presenta el paciente.

Abstract: The clinical presentation of a proximal femoral fracture is completely different between young and adult patients. Unlike closed proximal femoral fractures, the incidence of exposed fractures is found in the young population between 15 and 30 years of age. Osteonecrosis of the femoral head is one the complications we can find in this type of fractures. Avascular necrosis (AVN or osteonecrosis) is defined as the interruption of blood supply to the femoral head due to trauma, infection, alcohol or steroid use, resulting in bone necrosis, joint collapse and osteoarthrosis. The treatment will depend on the clinical presentation, age of the patient and when the diagnosis is made. This is a case report of a 16-year-old patient with a gunshot wound on the hip. Surgical cleansing and closed reduction plus internal fixation with a nail in the center of the spine were performed. A 3-year clinical and radiographic follow up was made, observing the evolution of the fracture and the subsequent avascular necrosis that the patient presented.

Phase I total hip replacement for severe hip osteoarthritis with proximal femoral fractures / 中国骨伤

OBJECTIVE@#To investigate the effect and prognosis of stage I total hip replacement in the treatment of severe hip osteoarthritis with proximal femoral fracture.@*METHODS@#From July 2014 to October 2017, 8 patients with severe end-stage hip disease and proximal femoral fracture were treated with stage I total hip replacement including 6 males and 2 females, aged 59 to 72 years old with an average age of 65 years old, involving 4 femoral head necrosis with proximal femoral fracture in the right side, 3 femoral head necrosis with proximal femoral fracture in the left side, and 1 left acetabular dysplasia with proximal femoral fracture in the left side. The average time from injury to operation was 7 days. Eight patients were treated with biologically elongated hip prosthesis.@*RESULTS@#Eight patients with stage I total hip arthroplasty were followed up for 12 to 48 months with an average of 31 months. During the follow-up period, there was no loosening or subsidence of the prosthesis. Harris score increased from 33 points (22 to 42 points) preoperatively to 87 points(82 to 90 points) at the last follow-up. Among them, 3 cases were excellent and 5 cases were good. Abandoned abduction and walked 3 months after operation. X-ray films during 3-6 months after operation showed that fracture healing was good, hip pain and function were improved significantly, and the quality of life was greatly improved.@*CONCLUSIONS@#Phase I total hip arthroplasty for severe hip osteoarthritis patients with proximal femoral fracture has the advantages of shortening the treatment time, alleviating patients'pain, reducing hospitalization costs and good prognosis.

The Clinical Pathway with Regional Alliance (CPRA) system for proximal femoral fractures in the southern region of Ibaraki prefecture: comparison of the proportion of patients who return to living at home from acute care and rehabilitation (kaihukuki) hospitals / Journal of Rural Medicine

Objective: We investigated whether elderly patients treated for a proximal femoral fracture would be able to return home.Patients and Methods: The subjects of this study were 834 patients. We defined the acute care hospital group as patients who returned home from the acute care hospital and the kaihukuki group as patients who were transferred from an acute care hospital to a rehabilitation hospital. We recorded the proportion of patients who returned home. We also analyzed walking ability and the Barthel index (BI) of patients.Results: After 2013, the proportion of patients who returned home from the acute care hospital fell below 20%. The proportion of patients who returned home from the kaihukuki hospital stayed within the 75–85% range. The BI before injury and at discharge was 86 and 76 points, respectively, in the acute care hospital group. The acute care hospital group included patients who walked without an aid before the injury or when leaving the hospital. In the kaihukuki group, the BI before an injury, at admission, and at discharge from the rehabilitation hospital was 85, 56, and 74 points, respectively. In the kaihukuki group, the ability of patients to walk recovered more slowly than that of patients in the acute care hospital group.Conclusion: Walking ability and BI are important factors for determining whether patients with a proximal femoral fracture are able to return home.

Treatment of the Proximal Femoral Fractures with Proximal Femoral Nail Antirotation (PFNA)

PURPOSE: To analyze the clinical and radiologic results of treatments in proximal femoral fracture with Proximal Femoral Nail-Antirotation (PFNA). MATERIALS AND METHODS: We retrospectively reviewed the results of 21 cases of proximal femoral fracture treated with PFNA from September 2006 to October 2007 which could be followed up for minimum of more than a year. The mean age was 61.5 (20~88) years old. Male were involved in 12 cases, female in 9 cases. The mean follow up was 14.3 (12~18) months. The Garden alignment index, Cleveland index, tip apex distance were evaluated by post-operative radiologic evaluation and complications of bone union, failure of internal fixation and deformity were evaluated by follow up radiologic findings. Clinical results were assessed by social function score of Jensen and mobility score of Parker and Palmer at last follow up. RESULTS: All fractures were united and the mean time to bone union was 15.7 (13~18) weeks. Garden alignment index showed good results of above 'good' in 15 cases (71.4%), Cleveland index showed 14 cases (66.4%) positioning in zone 5 and tip apex distance showed 17.81 (+/-5.65~27.52) mm in radiologic findings. The mean sliding of blade was 1.32 (0.34~2.94) mm in follow up radiologic findings and fracture of distal locking screw area was found in 1 case as a complication. Among 21 cases, the function before injury was completely recovered in 15 cases (71.4%) which were assessed by social function score of Jensen and 13 cases (61.9%) by mobility score of Parker and Palmer. CONCLUSION: We think that PFNA is effective osteosynthetic device for proximal femur fracture with satisfactory radiologic and clinical outcomes.

Salvage of failed treatment of proximal femoral fractures with total hip replacement / 中华创伤骨科杂志

Objective To analyze the causes for failed treatments of proximal femoral fractures and to evaluate the curative results of total hip replacement(THR)to salvage the failures.Methods A retrospective study was conducted for 23 consecutive cases of THR to salvage failed treatments of proximal femoral fractures from February 2002 to April 2005.There were 17 cases of femoral neck fracture,five cases of intertrochanteric frac- ture,and one case of femoral head fracture.Results Inadequate reduction after inadequate fixation,incorrect materials or technical errors in internal fixation were the most significant reasons for the failure of early treatment. Twenty-one of the 23 patients were available for fullow-up that ranged from 8 to 46 months(mean,32 months). No such complications as wound infection,hip dislocation,prosthesis breakage or deep venous thrombosis were found.Their mean Harris score increased from 48.3 preoperatively to 87.6 postoperatively.Condusions Re- duction,internal fixation,and fixation technique are very important to treatments of proximal femoral fractures. High energy trauma in young patients and osteoporosis in old patients make treatment of proximal femoral fractures even more difficult.THR is a satisfactory and safe way to salvage a failed treatment of proximal femoral fracture.

The treatment of proximal femoral fracture / 中华创伤骨科杂志

Proximal femur consists of femoral head, femoral neck and trochanter. The neck and trochanteric parts of femur are easy to get fractured under conbolution forces. As the conservative treatment tends to cause high rates of complication and mortality, more and more surgeons vote for early internal fixation in recent years. The best treatment for femoral neck fracture is now internal fixation with cannulate screws, especially for the patients with good bone density, fundus and intertrochanteric fractures as well as the type I, type Ⅱand part of type Ⅲfractures in Gardon's classification. Although intertrochanteric fractures are relatively stable, but internal fixation is necessary for good results and prevention of complications. DHS(dynamic hip screw)are advisable for A1, part of A2 and A3 intertrochanteric fractures in AO classification, especially for A1 cases. PFN (proximal femoral nail) is designed for intertrochanteric fractures, inversion and elevation intertrochanteric fractures. In order to get better prognosis in patients older than 70 years and with serious osteoporosis and A2 3, A3 3 fractures, we designed a special kind of prosthesis for them and therefore get satisfactory results.

Comparison between Gamma nail and DHS/Richard in treatment of proximal femoral fracture: a meta analysis / 中华创伤骨科杂志

Objective To asses the effects of Gamma nail and DHS/Richard (dynamic hip screw) in the treatment of proximal femoral fractures. Methods A meta analysis of all the relevant randomized controlled trials (RCTs) was performed. We included randomized and quasi randomized controlled trials in patients with proximal femoral fracture to compare Gamma nail and DHS/Richard. Results First we identified 88 papers on comparison of Gamma nail and DHS/Richard in the treatment of proximal femoral fractures published from 1969 to 2003. 7 trials involving 1256 patients were identified as meeting all the eligibility criteria. 3 investigators independently graded study quality and abstracted relevant data, including information on mortality rates, wound infection, function, revision in patients with a proximal femoral fracture. 4 trials, which included a total of 621 patients, provided detailed information on mortality rates over the first 6 postoperative months. We found there was no significant difference in the relative risk of death in the first 6 months postoperative between treatments of Gamma nail and those of compression hip screw (relative risk 1.17;P=0.51). 6 trials that included a total of 1083 patients provided data on operative complications. The risk of operative complications from Gamma nail fixation appeared to be higher than that from compression screw and side plate fixation but not higher than that from compression hip screw (relative risk 1.41; P=0.02). We also found an obvious increase in the relative risk of fracture of femoral shaft between Gamma nail and compression hip screw (relative risk 6.99; P=0.00). Patients treated with Gamma nail had a higher rate of revision compared with those with compression hip screw, but there was no significant difference between the two groups (relative risk 1.85; P=0.20). In addition, wound infection, operative blood loss and functional recovery were similar between the tow groups(relative risk 0.98 for wound infection and 1.02 for function). Operating time for Gamma nail patients was significantly less than that for DHS/Richard ones (P

Are High Risk Patients of Femoral Neck Fractures Predictable from the Severity of Osteoporosis? / 日本農村医学会雑誌

Proximal femur fractures (PFFs) are a major cause of disability in the elderly. Some reports say that osteoporosis is a factor contributing to PFFs and values of bonemineral density (BMD) can be used to predict PFFs. In this study we investigated thepossibility of using BMD monitoring to predict the risk of PFFs.<BR>This study compares a PFF group with a nonfracture control group. The selection criteria for both groups were female patients, age 60 and over, on whom dual energy xray absorptiometry (DXA) was performed. The PFF group was composed of 52 patients who were treated between Feb. 1997 and Nov. 1998 and DXA was performed within two weeks postoperatively. The nonfracture control group was made up of 27 patients who were treated for total knee replacement between April 1998 and Dec. 1998 and DXA was performed within two weeks preoperatively.<BR>Histograms were made using BMD data from lumbar and proximal femor measuring sites. The histograms were used to produce receiver-operating characteristic (ROC) curves. After analysing the histograms and ROC curves, two ranges of interest in each DXA report, neck and Wards were selected as the best sites to use when comparing the PFF and control groups.<BR>The two groups were compared to determine cut-off levels for PFFs. For the assessment of fracture risk of the patients with osteoporosis, we would like to propose for neck, 0.600g/cm<SUP>2</SUP> BMD in which sensitivity is 76% and specificity is 80%. And for Wards, 0.400g/cm<SUP>2</SUP> BMD in which sensitivity is 71% and specificity is 81%.
