Background: Isolated patellofemoral arthroplasty has gained new attention after recently published positive results. It is considered an intermediate treatment for the patient with isolated arthritis of the anterior compartment of the knee. Aim of this nationwide survey was to determine the current status of patellofemoral arthroplasty in Germany. Methods: All German departments of orthopaedic surgery, traumatology and general surgery with a yearly performance of at least fifty knee arthroplasties were asked to complete a standardized questionnaire. In the first part, surgeons were asked general questions about their department size, case numbers of knee arthroplasties per year and non-endoprosthetic treatment of isolated patellofemoral disorders. If patellofemoral arthroplasty was conducted, parameters concerning age, gender, duration of complaints, indication for surgery, surgical approach, type of endoprosthesis used, additional surgical treatments and failures were evaluated in the second part. Furthermore we asked for the reasons if no isolated patellofemoral arthroplasty was performed. Results: A total of 224 (30%) usable questionnaires were returned. Of 53420 knee arthroplasties performed per year, only 195 were isolated patellofemoral arthroplaties (0.37%). However, in 54 departments (24%), at least one isolated patellofemoral arthroplasty was performed with an average of 3.95 (1–20) procedures per year. The majority of patients were between 40 and 60 years old (40–60y: 56%; 20–40y: 8%, 60–80y: 35%, > 80y: 1%). Females were affected in 65% of patients. Etiology of isolated patellofemoral arthritis was believed to be idiopathic in 41% and traumatic in 8%. Patellofemoral dysplasia was held responsible in 47% and patellofemoral instability in 4% of cases. The main reason for failure and surgical revision was ongoing pain of the affected knee (40%). Negative attitude and disbelief towards the success of isolated patellofemoral arthroplasty were stated by the majority (62%) of non-users. A lack of appropriate indications was reported by 22% and missing know-how by 16%. Conclusions: Isolated patellofemoral arthroplasty has only little significance among surgeons performing knee arthroplasty in Germany. Although promising results were reported in the literature, the majority of surgeons do not believe in the success of the procedure

AIM: Total hip replacement is the most successful procedure since 3 decades. In the last years a lot of new helpful implants were introduced to the market, minimal invasive procedures are presented in increasing numbers and the technique of navigation is introduced. On the other hand there is no scientific proof of the benefit of these procedures. The objective of this study was to collect data about the different procedures and the common used implants.

METHOD: In a countrywide anonymous survey, 250 German trauma surgery and orthopaedic surgery departments were asked about their MIS procedures and their treatment strategies.(August 2006)

RESULTS: 112 of the questionnaires have been returned so far. We found 82% of the surgeons doing minimal invasive THR, 18% are doing more than 50% of all procedures in MIS technique, while 45% of the colleagues report, that the patients never ask for the procedure. Most of the surgeons (58%) define “minimal invasive” as the preservation of muscle, tendons and soft tissue, 1% as the preservation of bone and 41% as the length of skin incision (6–12cm). The most common MIS approach is the lateral (45%), followed by the anterior approach (25%) and the modified Watson-Jones approach (21%) and the MIS dorsal approach (19%) (Some use more than 1 approach). For standard procedure (not minimal invasive) there is most used the Kocher approach (51%), followed by Bauer approach (29%) and Smith-Petersen/Watson-Jones (19%). 23% use navigation and 51% are convinced, there is no sense in that.

66% do not use articular resurfacing, 33% are using short implants.

CONCLUSION: While the technique of MIS in THR is whidespread in Germany, an exact definition is still missing. Patients don’t expect MIS as much as surgeons perform it. Out of the variety of approaches a standard still has to be defined.

For minimal invasive procedure there is most used a lateral approach, for standard procedure the Kocher approach. New implants are used by every third surgeon, navigation by every fourth surgeon.

The aim of this surgery was to determine current practice amongst orthopaedic surgeons in New Zealand with regard to Anterior Cruciate Ligament Reconstruction.

All current members of the NZOA were sent a questionnaire on the numbers and proportions of grafts performed, methods of fixation, operative technique and return to sport.

One hundred and ten of 140 questionnaires were returned completed. Ninety two orthopaedic surgeons were performing ACL reconstructions. Eight per cent performed patellar tendon grafts in preference to hamstring grafts, whereas 16% preferred hamstring over patellar tendon grafts. Almost 2000 patellar tendon grafts at an average of just over 20 per surgeon are performed each year compared to just over 500 hamstring grafts at an average of just over 15 per surgeon. Metal interference screws were the most common fixation device in patellar tendon and hamstring grafts.

Patellar tendon grafts are the most common grafts used for ACL reconstruction with 80 % of those surveyed preferring to use patellar tendon over hamstring grafts. Metal interference screws were the most common fixation device. There is reasonable consensus regarding return to activity and sport.

Aims

There is little information about the optimum number of implants to be used in the surgical treatment of idiopathic scoliosis. Retrospective analysis of prospectively collected data from the Swedish spine register was undertaken to discover whether more implants per operated vertebra (implant density) leads to a better outcome in the treatment of idiopathic scoliosis. The hypothesis was that implant density is not associated with patient-reported outcomes, the correction of the curve or the rate of reoperation.

Aims. Diabetic foot care is a significant burden on the NHS in England. We have conducted a nationwide survey to determine the current participation of orthopaedic surgeons in diabetic foot care in England. Methods. A questionnaire was sent to all 136 NHS trusts audited in the 2018 National Diabetic Foot Audit (NDFA). The questionnaire asked about the structure of diabetic foot care services. Results. Overall, 123 trusts responded, of which 117 admitted patients with diabetic foot disease and 113 had an orthopaedic foot and ankle surgeon. A total of 90 trusts (77%) stated that the admission involved medicine, with 53 (45%) of these admissions being exclusively under medicine, and 37 (32%) as joint admissions. Of the joint admissions, 16 (14%) were combined with vascular and 12(10%) with orthopaedic surgery. Admission is solely under vascular surgery in 12 trusts (10%) and orthopaedic surgery in 7 (6%). Diabetic foot abscesses were drained by orthopaedic surgeons in 61 trusts (52%) and vascular surgeons in 47 (40%). Conclusion. Orthopaedic surgeons make a significant contribution to both acute and elective diabetic foot care currently in the UK. This contribution is likely to increase with the movement of vascular surgery to a hub and spoke model, and measures should be put in place to increase the team based approach to the diabetic foot, for example with the introduction of a best practice tariff.

Aims. This study sought to estimate the clinical outcomes and describe the nationwide variation in practice, as part of the feasibility workup for a National Institute for Health and Care Excellence (NICE) recommended randomized clinical trial to determine the optimal treatment of torus fractures of the distal radius in children. Methods. Prospective data collection on torus fractures presenting to our emergency department. Patient consent and study information, including a copy of the Wong-Baker Faces pain score, was issued at the first patient contact. An automated text message service recorded pain scores at days 0, 3, 7, 21, and 42 postinjury. A cross-sectional survey of current accident and emergency practice in the UK was also undertaken to gauge current practice following the publication of NICE guidance. Results. In all, 30 patients with a mean age of 8.9 years were enrolled over a six-week period. Of the 150 potential data points, data was captured in 146, making the data 97.3% complete. Pain scores were recorded at day 0 (mean 6.5 (95% confidence interval (CI) 5.7 to 7.3)), day 3 (4.4 (95% CI 3.5 to 5.2)), day 7 (3.0 (95% CI 2.3 to 3.6)), day 21 (1.2 (95% CI 0.7 to 1.7)) and day 42 (0.4 (95% CI 0.1 to 0.7)). Of the 100 units who participated in the nationwide survey, 38% were unaware of any local or national protocols regarding torus fractures, 41% treated torus fractures with cast immobilization, and over 60% of patients had follow-up arranged, both contradictory to national guidelines. Conclusion. We have demonstrated the severity, recovery trajectory, and variation in pain scores among children with torus fractures. We demonstrate excellent follow-up of patient outcomes using text messages. Despite national guidelines, there is significant variation in practice. This data directly informed the development of an ongoing nationwide randomized clinical trial – the FORearm Fracture Recovery in Children Evaluation (FORCE) study

Deep infection, the most serious local complication of total hip replacement, prompted a study of the records of 135 patients (137 hips) thus afflicted in a nationwide survey of Canada. Particular attention has been paid to the natural history of the infection, and the problems of diagnosis are described. Twenty-one patients died after the insertion, or removal, of the prosthesis, and of the survivors of the original 135 patients only eighteen have been able to retain the prosthesis without further problems with the wound. The remaining patients had the prosthesis removed, and most dry wounds. Certain suggestions are made on management. The advice that a second total hip prosthesis should be inserted after a deep infection of the first implant is not supported

To establish the current practice of spinal cord monitoring in units carrying out scoliosis surgery in the UK. To illustrate the benefit of routinely monitoring motor evoked potentials (MEPs). Questionaire: Nationwide survey of spinal monitoring modalities used by spinal units carrying out deformity surgery. 10 out of 27 units routinely measure motor evoked potentials (MEPs), the remainder use only sensory potentials (SEPs). There is significant variability in use of monitoring around the UK and we have compared this to the practice elsewhere in the world. We report the case of a thirteen year old girl who underwent posterior instrumentation for correction of an idiopathic scoliosis. Intra-operatively there was a significant reduction in the amplitude of the MEPs without any corresponding change in the SEPs. These changes reversed when the correction was released. The surgery was abandoned and was carried out as a staged procedure, initially anteriorly then posteriorly. There was no loss of motor potentials during either operation and no post operative neurological abnormalities. We propose that the changes noted initially were due to transient ischaemia of the cord which would not have been detected without MEPs and may have led to long term sequelae. This highlights the safety benefit of routinely using MEPs in scoliosis surgery. Nationally there is wide variation in the monitoring of spinal cord function during scoliosis surgery. We feel that monitoring of motor potentials is a vital component in ensuring scoliosis surgery is as safe as possible

Purpose: As the prevalence of diabetes mellitus (DM) in people over 60 years of age is expected to increase, the number of diabetic patients who undergo total hip and knee arthroplasty should increase concordantly. In general, patients with DM have significantly increased risk for adverse events following arthroplasty. The goal of this study was to determine whether the quality of glycemic control affected the incidence of perioperative complications in the hospital following joint replacement. Method: From 1988 to 2003, the Nationwide Inpatient Survey (NIS) recognized 65,769 patients who had DM and underwent joint replacement surgery. In this retrospective study, bivariate and multivariate analyses compared patients with uncontrolled (n=2,872) and not uncontrolled (n=62,897) DM regarding common surgical and systemic complications, mortality, and hospital course alterations. Glycemic control was determined by physicians’ assessments based upon the American Diabetes Association guidelines using a combination of patients’ self-monitoring of blood-glucose testing, the hemoglobin A1C, and related complications. Results: Patients with uncontrolled DM routinely had an increased length of stay and increased inflation-adjusted costs after surgery (p< 0.001). Uncontrolled patients also had significant increases in the incidence of stroke, pneumonia, urinary tract infection, post-operative hemorrhage, wound infection, and death (p< 0.001). Conclusion: Patients with well-managed glycemic control have fewer comorbidities in general. Patients with uncontrolled DM exhibited significantly increased risks for surgical and systemic complications, higher mortality, increased length of stay, and higher hospital charges during the index hospitalization following arthroplasty. The consequences are increased cost, greater burden on the healthcare system, and greater risk to these patients

Aims: Nationwide, computer-based survey of all total joint arthroplasties performed in Finland has been carried out since January 1980. From these records a cohort of 9,443 patients, with 80,734 person-years, after primary operation with a total polyethylene-on-metal knee arthroplasty (TKA) has been followed up for cancer. In 1999 we published the material until December 31, 1996. The standardized incidence ratio (SIR) for all cancers was 0.98. The SIRs for non-Hodgkin lymphoma (1.40), Hodgkinñs disease (1.24), multiple myeloma (1.54) and prostate cancer (1.49) were increased, but only that of non-Hodgkin lymhoma was statistically signiþcant 3 to 10 years after the operation. The overall cancer risk after TKA done for primary osteoarthrosis appeared to be negligible. Material and methods: Follow-up for cancer was undertaken using the þles in the population-based, nationwide Finnish Cancer Registry, employing personal identiþcation numbers. Follow-up for cancer started at the date of þrst knee replacement and ended on emigration, death, or 31 December 2000, whichever occurred þrst. No subject was lost to follow-up. Standardized incidence ratios (SIRs) were calculated by dividing observed numbers of cases by expected numbers. Results: There were 2,001 men and 7,442 women left in the cohort to be followed-up. Numbers of person-years are now 15,679 and 650,552, respectively. The mean duration of follow-up per person was therefore 8,5 years. During the 21-year follow-up period, 358 cases of cancer occurred in the male subjects. The expected number was 349. In the female subjects 801 cases of cancer were observed vs. 804 expected. Combining data for men and women, the SIR for cancer at all sites was 1.00. SIRs were signiþ-cantly lower in relation to cancers of the lung (0.69), and colon (0.77). The incidence of risk of colon cancer was lower than would have been expected only in women (SIR 0.70). As far as cancers of the urinary organs is concerned, the SIR was within unity (SIR 1,03). The overall incidence of non-Hodgkin lymphoma (extranodal sites included) was elevated, but without any statistical signiþ-cance (SIR 1.22). The SIR values for multiple myeloma and leucemia have reduced to 0.80 and 0.53. Conclusions: We conclude, that this large nation-wide material could not establish any association between TKA and the all-over incidence of remote or adjacent cancers; on the contrary incidences of certain cancers were in fact lower than those reported in the formed material with four years less follow-up. All the alarming SIRs in the former material, especially those with non-Hodgin lym-phoma, urinary tract cancers and leucemia, have now reduced and are less than unity
