Abstract
Fast track programs have been introduced to reduce perioperative complication rates and to quickly reintegrate the patient into everyday life. The aim of this retrospective case-control study was to identify patient characteristics and patient-independent factors that influence fast track programs in hip arthroplasty. A total of 1138 patients were examined. A hospital stay of more than seven days was used to define the case group. In addition to the causes for the longer hospitalisation, age, sex, BMI, chronic nicotine and alcohol abuse, ASA score, surgical duration, anaemia and blood transfusion as well as concomitant diseases were assessed. The statistical analysis included two-sample t-test, chi-square test and logistic regression analyses. An 95% confidence interval was calculated (p<0.05). 16.9% of patients could not leave the hospital on the seventh day. The main causes were delayed wound healing (69.4%), increased CRP (43.0%>100 mg/l), and internal complications (19.7%). At a mean of 69.2 ± 10.7 years, the age of the case group was significantly higher than that of the control group, which had a mean of 63.3 ± 10.3 years (p<0.001). Cardiac comorbidities (p<0.001), BMI (p=0.023), and alcohol consumption (p<0.001) increased the risk for longer hospitalisation. Significant patient-independent factors were duration of the surgery (p<0.001) and transfusion (p<0.001). Successful application of fast-track hip arthroplasty is possible for every patient. However, longer hospi- talisation and delayed discharge must be taken into account for patients with advanced age, cardiac comorbidities, alcohol consumption, and high BMI.

Cemented conical stems can be removed more easily than cylindrical stems, regardless of cone angle in revision knee arthroplasty. Arch Orthop Trauma Surg 2018; 138:1747-1754. [PMID: 30367254 DOI: 10.1007/s00402-018-3053-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND According to literature, more than 30% of revised knee arthroplasties will require at least one re-revision. Practical experience has shown that there are considerable product-specific differences in the explantability of cemented long-stem prostheses. In the registers of successful implants, stem geometry varies considerably between the manufacturers. However, comparative data on explantability of the respective stems are missing. Objective of the present study was to identify a correlation between the geometry of a smooth cemented long stem and the necessary explantation energy required until failure of the implant-cement interface occurs. METHODS Eight cemented stems with different conical profile angles (0°-3°) were explanted in a reproducible biomechanical setup each six times to evaluate the correlation between the stem design and the required explantation energy. RESULTS The average explantation energy was highest in the case of the cylindrical stem, at 18.1 ± 3.6 J. At a cone angle of 0.25°, it was just 12.1 ± 2.1 J (p < 0.001) and dropped beyond 0.5° to an average of 5.7 ± 1.8 J (p < 0.001). Between 0.5° and 3°, no significant difference in the required extraction energy was observed. CONCLUSIONS Whereas smooth conical stems can mostly be removed easily, an early decision in favour of osteotomy or fenestration can be taken in the case of cylindrical cemented stems.

The learning curve in short-stem THA: influence of the surgeon's experience on intraoperative adjustments due to intraoperative radiography. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2017; 28:269-275. [PMID: 29030711 PMCID: PMC5775369 DOI: 10.1007/s00590-017-2049-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Accepted: 09/12/2017] [Indexed: 12/22/2022]
Abstract
Introduction Short-stem THA has become increasingly popular over the last decade. However, implantation technique differs from conventional THA and thus possibly involves a distinct learning curve. The purpose of this study was to evaluate the value of intraoperative radiography and the influence of the surgeon’s experience on intraoperative adjustments in short-stem THA. Methods A total of 287 consecutive short-stem THAs, operated by a total of 24 senior consultants, consultants and residents in training, were prospectively included. Intraoperative radiography was performed after trial reduction. Preoperative planning and intraoperative outcome with regard to positioning, sizing of components as well as resulting offset and leg length were compared. Frequency, reason and type of intraoperative adjustments were documented in relation to the surgeon’s experience. Operation time was assessed. Results One hundred and fifty-six (54.4%) procedures were carried out by one of three senior consultants, and a total of nine consultants and 12 residents in training performed 105 (36.6%) and 26 (9.0%) operations, respectively. In 121 cases (42.2%), intraoperative adjustments were made following intraoperative radiography. Intraoperative adjustments of one or more components were made by senior consultants in 51 cases (32.7%), by consultants in 53 cases (50.5%) and by residents in 17 cases (65.4%), respectively. The most common cause was undersizing of the stem. Operation time varied markedly between groups of surgeons. Discussion Short-stem THA involves a learning curve. Intraoperative radiography is decisive for prevention of malpositioning and undersizing of components, as well as loss of offset and leg length discrepancies. Hence, it should be considered mandatory, especially for less experienced surgeons.

Abstract
Introduction: Revision arthroplasty of the hip is becoming increasingly important in recent years. Early primary arthroplasty and longer life expectancy of the patients increases the number of revision surgery. Revision surgery of hip arthroplasty is major surgery for the patients, especially the elderly, with significant risks concerning the general condition of the patient. The aim of this work is to evaluate the outcome of bipolar hip arthroplasty as a salvage procedure for treatment of loosening of the acetabular cup with significant acetabular bone defects after total hip replacement (THR) in multi-morbid patients. Patients and methods: During the period from January 1st 2007 to December 31st 2011 19 revision hip surgeries were performed in 19 patients, in which the loosened acetabular cup was replaced by a bipolar head. The examined patient group consisted exclusively of female patients with an average of 75 years. The predominant diagnosis was “aseptic loosening” (84.2%). All patients in our study were multi-morbid. We decided to resort to bipolar hip arthroplasty due to the compromised general condition of patients and the major acetabular bone defects, which were confirmed intraoperatively. The postoperative follow-up ranged from 0.5 to 67 months (average 19.1 months). Results: Evaluation of the modified Harris Hip Score showed an overall improvement of the function of the hip joint after surgery of approximately 45%. Surgery was less time consuming and thus adequate for patients with significantly poor general health condition. We noticed different complications in a significant amount of patients (68.4%). The most common complication encountered was the proximal migration of the bipolar head. The rate of revision following the use of bipolar hip arthroplasty in revision surgery of the hip in our patients was high (21%). Despite the high number of complications reported in our study, we have noticed significant improvement of hip joint function as well as subjective pain relief in the majority of patients. We clearly achieved clinically satisfactory results in 14 patients. Conclusion: Bipolar hip arthroplasty is by no means to be regarded as standard procedure in revision surgery of THR. It provides an option or salvage procedure for patients with poor general condition in whom the quickest possible surgical intervention preserving mobility is required. This is particularly true for multi-morbid patients in whom sufficient acetabular fixation is not possible.

Abstract
BACKGROUND As a consequence of limited personnel and financial resources, the increase in total hip arthroplasties places higher demands on orthopedic surgeons. OBJECTIVES In order to maintain high quality treatment, the correlation between surgical experience, duration of surgery and risk of complications was examined. MATERIAL AND METHODS The surgery time and, if applicable, complications (until discharge from hospital) of 1129 total hip arthroplasties over a period of 4 years were evaluated retrospectively. RESULTS The group of most experienced surgeons needed an average time of 53.2 ± 17.6 min for each implantation, followed by moderately experienced surgeons (74.5 ± 25.5 min) and less experienced surgeons (80.8 ± 21.9 min). Of all included cases, a total of 41 complications until discharge from hospital occurred. The number of complications increased with duration of surgery, whereby the risk of complications was significantly lower for shorter surgery times conducted by the most experienced surgeons as well as moderately experienced surgeons. The complication risk of less experienced surgeons remained constant independent of surgery duration. CONCLUSION These results underline the recommendations of the German Endocert system, which determine a minimum number of total joint arthroplasties as a quality indicator not only for hospitals but also for individual surgeons.

Abstract
INTRODUCTION Studies which deal with the problems of total hip arthoplasty (THA) in patients with neuromuscular impairments are rare. The aim of this study was to examine whether THA for painful coxarthrosis in such patients relieved pain and improved functional outcome and how high the complication rate was. MATERIAL AND METHODS For this study 10 patients (13 hips) with neuromuscular impairment who had received a total hip arthroplasty for painful coxarthrosis were retrospectively identified. A chart review determined the preoperative functional level. For postoperative evaluation all patients completed a questionnaire, including a self-created modified hip score. RESULTS The average age of the patients at the time of follow-up was 42.1 years (range 26.5-62.2 years, standard deviation SD 9.9 years) and the minimum follow-up was 24 months (average 80.3 months, range 24-143 months, SD 47 months). Pain relief was obtained for all patients but two patients had a postoperative dislocation and four patients had a major complication (infection) requiring removal of the implant. Therefore, the follow-up rate at the final examination with completed questionnaires was 69% (9 out of 13 excluding patients with removal of THA). These patients showed an improved function from 42.2-83.66 points in the hip score (p=0.0006) and there was general satisfaction with the procedure. DISCUSSION Total hip arthroplasty can provide improved function in patients with neuromuscular impairment and severe coxarthrosis. The rate of complications was moderate in this series; however, the high infection rate in these patients should be kept in mind.

Abstract
Treatment of medial femoral fractures in elderly patients with cemented hip hemiarthroplasty (HEP) is a widely established procedure. The main problems with this procedure are complications associated with soft tissue damage and prolonged immobilization. The aim of this study was to compare the clinical and radiological results after HEP implantation using either an anterior minimally invasive (MIS) approach or a regular transgluteal (TG) approach. In this retrospective study the results of 55 consecutive MIS and 54 consecutive TG approaches for implanted HEP after medial femoral fracture were compared. The time of successful mobilization, duration of the i.v. analgesia as well as the occurrence of any perioperative complications were recorded. The femoral offset, leg length and the femoral alignment were analyzed radiologically. The MIS group could be mobilized earlier (MIS 2. pod vs. TG 4. pod, p <0.01) but the need for i.v. applied analgesia was prolonged (MIS 4.4 pod vs. TG 3.5 pod, p=0.04). In the MIS group the number of perioperative complications was less than in the TG group (MIS 7% vs. TG 17%, p <0.05). The early functional advantages of MIS after HEP implantation for medial femoral fractures are evident also within an elderly group of patients.

Abstract
Despite numerous publications, new guidelines for the treatment of acute pain and efforts from a number of initiatives, there is still a tremendous need for improvement in postoperative pain therapy. One of the reasons for the shortcomings in the care of patients with postoperative pain is the lack of applicability of guidelines in daily clinical practice. Therefore, simple but effective and easy to implement concepts need to be developed. In the following review, different concepts that have been developed over recent years are presented and evaluated for their effectiveness. One of these is the notion of balanced analgesia, currently probably one of the most widely used perioperative therapy concepts. The idea of this concept is to reduce the doses of analgesics, e.g. opioids, through combinations of different classes of analgesics, thereby reducing their side effects. However, recent studies and essential meta-analyses indicate pitfalls using this concept. The pros and cons will be discussed and ideas on how to deal with balanced analgesia in daily practice will be given. Another pain concept of "procedure-specific postoperative pain therapy", is an appealing idea of an international initiative from surgeons and anaesthesiologists and an essential part of the German S3 guidelines for acute pain released last year. Critical evaluation of the available recommendations for procedure-specific analgesia together with the presentation of relatively simple but evidence-based algorithms for specific procedures may help to implement this concept in clinical routine.

Abstract
Given the rising prevalence of obesity, surgeons and hospitals must become more familiar with the treatment and operative management of obese patients. Several additional pre- and postoperative considerations must be involved such as appropriate assessment of comorbidities and requirements for special equipment. There are still very few data regarding morbidly obese patients with BMIs >50 kg/m(2). After a general literature review of operative management of obese patients, we report on fracture care of the lower limb in such patients with custom-made Ilizarov ring fixators. We found them suited to bear enormous weight-loading but that associated comborbidities can limit successful fracture care.

Abstract
The objective of this study was to examine the influence of obesity on the rate of infection, dislocation, and overall complications in a group of male patients undergoing primary total hip arthroplasty (THA). The study involved a retrospective review of the association of body mass index (BMI) and dislocation, infection, and complications on 255 consecutive male patients who received a THA. BMI of 40 and greater had significantly more dislocations and approached significance for infections. The present study suggests that the risk of infection and dislocation increases only in highly obese males (BMI > 40) in contrast to other studies that have reported a higher risk infection, dislocation, and complications with a BMI of obesity in females (BMI > 30).

Abstract
In times of plentiful nutrition an environmental advantage turns into a problem - obesity. Apart from an increase in morbidity and overall mortality the development of osteoarthrosis is well documented. Pre-arthrotic conditions may arise from trauma and can lead, depending on the pattern of injury, to full-blown arthrosis. The presence of obesity can play the role of a relevant progressive factor in this setting. Here we report about the case of an obese man (BMI 53.5 kg/m(2)), who suffered a fracture of the femoral head with acetabular participation (Pipkin IV) as well as a fracture of the tibial plateau. Operative management and rehabilitation were followed by gastric bypass surgery for weight reduction. The case is discussed with regard to the present literature.
