THA with large and small neck stem angle prosthesis can better recover the function of hip joint, but large neck stem angle can reduce the degree of postoperative pain and improve the quality of life of patients.
THA with large and small neck stem angle prosthesis can better recover the function of hip joint, but large neck stem angle can reduce the degree of postoperative pain and improve the quality of life of patients.Periprosthetic infection after hip replacement is a clinical catastrophic disease, which often leads to the failure of the prosthesis. It needs the combination of systemic antibiotics to cure the infection, which brings huge burden to doctors and patients. There are strict indications for debridement and one-stage revision of the prosthesis, and few cases meet the requirements. The second revision is still the gold standard for the treatment of periprosthetic infection. It is suitable for all infection conditions and has a high success rate. On the second phase of renovation, the antibiotic sustained release system plays a key role, and the carrier of antibiotic sustained-release system is the focus of current research, including classic bone cement and absorbable biomaterials. Bone cement has strong mechanical strength, but the antibiotic release shows a sharp decline trend; the absorbable biomaterials can continuously release antibiotics with high concentration, but the mechanical strength is poor, so it could not use alone. The combination of bone cement and absorbable biomaterials will be an ideal antibiotic carrier. PMMA is the most commonly used antibiotic carrier, but the antibiotic release concentration is decreased sharply after 24 hours. Disodium Cromoglycate mouse It will be difficult to control the infection and increase the risk of bacterial resistance if it is lower than the minimum inhibitory concentration. The biodegradable materials can release antibiotics completely, with long release time and high concentration, but low mechanical strength. Antibiotic spacer plays an important role in the control of infection. In the future, how to further extend the antibiotic release time of antibiotic sustained-release system, increase the amount of antibiotic release and maintain the mechanical strength of the material will be studied.
To analyze the clinical efficacy of hip arthroplasty with femoral calcar prosthesis and proximal femoral nail fixation(PFNA) in the treatment of elderly patients(≥80 years old) with unstable intertrochanteric fractures(Evans Ⅲ, Ⅳ).

From June 2016 to March 2018, 60 elderly patients with unstable intertrochanteric fractures treated with prosthetic replacement and PFNA were retrospectively analyzed. According to the surgical methods, they were divided into PFNA group and prosthesis group. In PFNA group there were including 21 males and 15 females, with an average age of(84.3± 2.9) years old;in the prosthetic group, there were 10 males and 14 females with an average age of (82.9±2.4) years old. The operation time, hemoglobin difference between preoperative and postoperative 1 day, postoperative ambulation time, hospitalization time and complications were observed and compared between the two groups. Harris hip score was performed 3 and 12 months after operation.

All patients were followed up for 12 to 24 moroplasty and improve the quality of life.

To compare the accuracy of three methods for measuring the length of both lower limbs in hip arthroplasty for femoral neck fracture in the elderly, and to introduce a "shoulder to shoulder" anatomical location marking method for femur.

From January 2017 to January 2019, 90 elderly patients with femoral neck fracture were treated with hip replacement, including 39 males and 51 females, aged 65 to 96(78.0±7.4) years, 56 cases of total hip and 34 cases of hemi hip. According to garden classification, there were 7 cases of typeⅡ, 63 cases of type Ⅲ and 20 cases of type Ⅳ. The patients were divided into three groups according to different measurement methodscontralateral contrast method (group A) of 19 cases, shuck test method (group B) of 28 cases, and "shoulder to shoulder" anatomical marker localization method (Group C) of 43 cases. The accuracy of the three methods was compared by measuring the length difference of lower limbs in vitro and imaging.

All patients completed the operation successfully. Afterer" anatomic localization marking method can reduce the length of lower limbs simply, effectively and accurately in the elderly patients with femoral neck fracture hip replacement.

To investigate how to place the anteversion of acetabular prosthesis more reasonably in patients with lumbar degenerative kyphosis.

A total of 122 patients with degenerative kyphosis of lumbar spine who underwent total hip arthroplasty from December 2017 to October 2019 were included and divided into experimental group and control group, 61 cases in each group. In experimental group, there were 25 males and 36 females, with a median age of 67.0 years;the median course of disease was 46.0 months;the functional pelvic plane with acetabular anteversion was set according to different types of pelvic anterior plane bracket. In control group, there were 27 males and 34 females, with a median age of 67.0 years;the median course was 42.0 months;in control group, the anteversion was set by the traditional method. The patients were followed up for 3 months. The operation time and blood loss were recorded. The incidence of infection and dislocation within 3 months was counted. Harris score before and 3 months after e obtained with the help of pelvic anterior plane reference bracket in hip arthroplasty with lumbar degenerative kyphosis.
According to the preoperative evaluation and classification of patients, better functional anteversion of acetabular prosthesis can be obtained with the help of pelvic anterior plane reference bracket in hip arthroplasty with lumbar degenerative kyphosis.
To explore the value of 3D-printed navigation template using in total hip arthroplasty(THA)for developmental dysplasia of the hip (DDH).

Twenty five patients with DDH underwent total hip arthroplasty from February 2016 to May 2018 were analyzed retrospectively, including 4 males and 21 females, aged from 40 to 75 years old. Among them, 5 cases were Crowe typeⅡ, 14 cases were Crowe type Ⅲ and 6 cases were Crowe type Ⅳ. Twelve cases of them underwent THA with the 3D printing navigation plate, another 13 cases underwent the same operation but without the aid of navigation templates. All patients were treated by the same operators. The operating time, intra- and post-operative hemorrhage and Harris Hip Score(HHS) at six months postoperativelywere compared, anteversion angle, abduction angle and the distance from rotation center to the ischial tuberosity connection between ipsilateral and contralateral sides were also compared.

All of the patients were followed up for 12 to 26 months. The operation time, intra- and post-operative hemorrhage and Harris score in the 3D printing group were better than those in the conventional hip replacement group(
<0.05). There were no significant differences in anteversion angle, abduction angle and the distance from rotation center to the ischial tuberosity connection between ipsilateral and contralateral sides in 3D printing group (
>0.05). The abduction angle and the distance from rotation center to the ischial tuberosity connection were significantly different between the two sides in the traditional group (
< 0.05), the abduction angles had no statistical difference (
=0.487) between two sides.

The 3D-printed operation navigation template technique is an individualized, accurate and promisingtechnique for THA with DDH.

To investigate the influence of total hip arthroplasty on the changes of spine pelvic parameters in patients with hip spine syndrome.

From January 2013 to October 2014, 22 patients (26 hips) with hip spine syndrome accompanied by necrosis of femoral head, hip osteoarthritis and congenital dysplasia of hip were treated with total hip arthroplasty. There were 12 males and 10 females with an average age of 58.4 years (range, 45 to 76 years). The course of disease was 1.5 to 25 years with an average of 12.8 years. Before and after the operation, the anteroposterior, full length radiographs of both lower limbs, thoracolumbar spine and pelvis in standing position were routinely taken. The balance parameters of spine pelvis coronal plane and sagittal plane before and after the replacement were measured. Visual analogue scale (VAS), Oswestry Disability Index (ODI) and Harris score were performed before and after the operation.

All cases were followed up for 21 to 52 (32±8) months. No infection, prosthesis subsiy improved, and the short term and medium-term effects are satisfactory.This article considers two areas of practice that are fundamental to the provision of high-quality nursing care for people experiencing acute pain the initial recognition of pain, and the formal assessment of pain. The initial recognition of a patient's pain is a subject that is frequently overlooked in the literature. However, if nurses are unable to identify that a patient is experiencing pain, then a formal pain assessment may not take place, which in turn negatively affects the quality of any subsequent pain management. This article explores some of the barriers to the initial recognition of pain and examines how a formal pain assessment can support optimal patient care.
Quantitative research designs are broadly classified as being either experimental or quasi-experimental. Factorial designs are a form of experimental design and enable researchers to examine the main effects of two or more independent variables simultaneously. They also enable researchers to detect interactions among variables.

To present the features of factorial designs.

This article provides an overview of the factorial design in terms of its applications, design features and statistical analysis, as well as its advantages and disadvantages.

Factorial designs are highly efficient for simultaneously evaluating multiple interventions and present the opportunity to detect interactions amongst interventions. Such advantages have led researchers to advocate for the greater use of factorial designs in research when participants are scarce and difficult to recruit.

A factorial design is a cost-effective way to determine the effects of combinations of interventions in clinical research, but it poses challenges that need to be addressed in determining appropriate sample size and statistical analysis.
