Genu valgum is a common presentation in paediatric patients with congenital limb deformities. The aim of this study is to assess the outcome of guided growth surgery in paediatric patients referred via our physiotherapy pathway with isolated genu valgum and associated patellar instability. Patients were identified from our prospective patellar instability database. Inclusion criteria was acquired or congenital genu valgum associated with patellar instability in skeletally immature patients. The mechanical lateral-distal femoral angle was assessed on long leg alignment radiographs (mLDFA <85 degrees). Surgical treatment was the placement of a guided growth plate (PediPlate, OrthoPediatrics, USA) on the medial distal femoral physis (hemi-epiphysiodesis). KOOS-child scores were collected pre-operatively and post-operatively (minimum at 6 months).Introduction
Materials & Methods
Femoroacetabular impingement (FAI) causes anterior hip pain, labral tears and damage to the articular cartilage leading to early osteoarthritis of the hip. Surgical hip dislocation and osteoplasty of the femoral neck and acetabular rim is a technique pioneered by the Bernese group for the treatment of FAI. We present and discuss our results of this technique. Functional outcome was measured in hips with over 12 month follow-up using the Oxford hip and McCarthy non-arthritic hip scores pre- and post-operatively.Introduction
Methods
The Ponseti method is the gold standard treatment for clubfoot. It begins in early infancy with weekly serial casting for up to 3 months. Globally, a commonly reported barrier to accessing clubfoot treatment is increased distance patients must travel for intervention. This study aims to evaluate the impact of the distance traveled by families to the hospital on the treatment course and outcomes for idiopathic clubfoot. No prior studies in Canada have examined this potential barrier. This is a retrospective cohort study of patients managed at a single urban tertiary care center for idiopathic clubfoot deformity. All patients were enrolled in the Pediatric Clubfoot Research Registry between 2003 and April 2021. Inclusion criteria consisted of patients presenting at after percutaneous Achilles tenotomy. Postal codes were used to determine distance from patients’ home address to the hospital. Patients were divided into three groups based on distance traveled to hospital: those living within the city, within the Greater Metro Area (GMA) and outside of the GMA (non-GMA). The primary outcome evaluated was occurrence of deformity relapse and secondary outcomes included need for
Aim. Recurrence of bone and joint infection, despite appropriate therapy, is well recognised and stimulates ongoing interest in identifying host factors that predict infection recurrence. Clinical prediction models exist for those treated with DAIR, but to date no models with a low risk of bias predict orthopaedic infection recurrence for people with surgically excised infection and removed metalwork. The aims of this study were to construct and internally validate a risk prediction model for infection recurrence at 12 months, and to identify factors that predict recurrence. Predictive factors must be easy to check in pre-operative assessment and relevant across patient groups. Methods. Four prospectively collected datasets including 1173 participants treated in European centres between 2003 and 2021, followed up to 12 months after surgery for orthopaedic infections, were included in logistic regression modelling [1–3]. The definition of infection recurrence was identical and ascertained separately from baseline factors in three contributing cohorts. Eight predictive factors were investigated following a priori sample size calculation: age, gender, BMI, ASA score, the number of prior operations, immunosuppressive medication, glycosylated haemoglobin (HbA1c), and smoking. Missing data, including systematically missing predictors, were imputed using Multiple Imputation by Chained Equations. Weekly alcohol intake was not included in modelling due to low inter-observer reliability (mean reported intake 12 units per week, 95% CI for mean inter-rater error −16.0 to +15.4 units per week). Results. Participants were 64% male, with a median age of 60 years (range 18–95). 86% of participants had lower limb orthopaedic infections. 732 participants were treated for osteomyelitis, including FRI, and 432 for PJI. 16% of participants experienced treatment failure by 12 months. The full prediction model had moderate apparent discrimination: AUROC (C statistic) 0.67, Brier score 0.13, and reasonable apparent calibration. Of the predictors of interest, associations with failure were seen with prior operations at the same anatomical site (odds ratio for failure 1.51 for each additional prior surgery; 95% CI 1.02 to 2.22, p=0.06), and the current use of immunosuppressive medications (odds ratio for failure 2.94; 95% CI 0.89 to 9.77, p=0.08). Conclusions. This association between number of prior
The burden of metastatic bone disease (MBD) in our Canadian cancer population continues to increase. MBD has a significant effect on patient morbidity, mortality, and health-related quality of life (HRQOL). There are various technical options used to surgically stabilize MBD lesions, surgical decision-making is variable and largely dependent on anatomic and surgeon-based factors. There is a paucity of research examining how surgical decision-making for MBD can be modified or individualized to improve quality of life (QOL) and functional outcomes, while more accurately aligning with patient-reported goals and expectations. The objective of this study was tosurvey MBD patients, support persons, physicians, and allied health care providers (HCP) with the goal of identifying 1) important contributors to HRQOL, 2) discordance in peri-operative expectations, and 3) perceived measures of success in the surgical management of MBD. This project is a longitudinal patient-engaged research initiative in MBD. A survey was developed based on HRQOL themes in the literature and based on feedback from our patient research partners. Participants were asked to identify 1) important contributors to HRQOL and 2) perceived measures of success relevant to the surgical management of MBD. Participants were asked to rank themes from ‘extremely important’ to ‘not important at all’. Using open-ended questions, participants were asked to identify areas of improvement. Responses from the open-ended questions were analyzed by an experienced qualitative researcher using conventional content analysis. Participant's demographics were calculated using descriptive statistics. Concordance or discordance of perceived measure of success was assessed via a Chi-Square test of independence. All statistical analyses were performed using IBM SPSS® software. Nine patients, seven support persons, 23 orthopaedic surgeons, 11 medical oncologists, 16 radiation oncologists, 16 nurses, and eight physiotherapists completed the survey. Regarding perceived measures of success, increased life expectancy (p Two main themes emerged around the timeliness of surgical care and the coordination of multidisciplinary care from patients and support persons. Patients and support persons expressed a sense of urgency in progressing to
This study aimed to evaluate the clinical outcomes of paediatric patients who underwent a retrograde drilling treatment for their osteochondritis dissecans (OCD) of the talus. The secondary purpose was to identify factors that are predictive of a failure of the treatment. A retrospective study was done. All patients treated for talar OCD between 2014 and 2017 were reviewed to extract clinical and demographic information (age, sex, BMI, OCD size and stability, number of drilling, etc). Inclusion criteria were: (1) talar OCD treated with retrograde drilling, (2) less than 18 years, (3) at least one available follow up (4) stable lesion. Exclusion criteria was another type of treatment for a the talar OCD. Additionally, all pre-operative and post-operative medical imaging was reviewed. Outcome was classified based on the last follow-up appointment in two ways, first a score was attributed following the Berndt and Harty treatment outcome grading and second according to the necessity of a second surgery which was the failure group. Chi-square and Mann-Whitney tests were used to compared the success and failure group. Seventeen patients (16 girls and 1 boy, average age: 14.8±2.1 years) were included in our study group. The mean follow up duration was 11.5 (±12) months. Among this population, 4/17 (24%) had a failure of the treatment because they required a second
This study presents patient-reported quality of life (QoL) over the first year following surgical debridement of long bone osteomyelitis. It assesses the bone involvement, antimicrobial options, coverage of soft tissues, and host status (BACH) classification as a prognostic tool and its ability to stratify cases into ‘uncomplicated’ or ‘complex’. Patients with long-bone osteomyelitis were identified prospectively between June 2010 and October 2015. All patients underwent surgical debridement in a single-staged procedure at a specialist bone infection unit. Self-reported QoL was assessed prospectively using the three-level EuroQol five-dimension questionnaire (EQ-5D-3L) index score and visual analogue scale (EQ-VAS) at five postoperative time-points (baseline, 14 days, 42 days, 120 days, and 365 days). BACH classification was applied retrospectively by two clinicians blinded to outcome.Aims

Introduction. Restoration of mechanical axis is one of the main aims during Total Knee Arthroplasty (TKA)
Aim. The pathogenesis of non-union is multifactorial. Path biological factors, mechanical factors, and low-grade-infection contribute to impaired bone healing. Aim of this study was to determine the rate of low-grade-infection in patients with long bone non-union of the lower extremity without signs of acute infection, the influence of CRP (C-reactive protein), and the outcome. Method. In a retrospective study (2003–2013), all patients who underwent
Perioperative fracture during routine THA represents one of the “not so fresh” feelings that occur for both patients and surgeons. With the increase in the use of uncemented implants and MIS techniques this truly is a problem on the rise. We have examined and quantified the risk factors associated with proximal femoral fracture during THA. Risk factors (risk ratios) identified were: uncemented stems (8.9), anterolateral approach (7.4) and female gender (2.2). Fortunately, treatment with cerclage wiring for uncemented stems has facilitated excellent stem stability and acceptable survivorship with many different femoral component designs. Reduced proximal geometry stems that better match the endosteal osseous anatomy have reduced fracture rates at our institution and maintained excellent stem survivorship. New data examining this design will be presented. In our series, cemented stems, however, had decreased survivorship in the presence of a proximal femoral fracture. MIS techniques may accelerate rehabilitation but they certainly permit limited visibility of the proximal femoral and acetabular anatomy and may result in less accurate component position. Relatively high fracture rates in series of MIS-THA have been reported. A bigger concern, however, is the unrecognised fracture that displaces postoperatively and requires a return to

Presenters Position:. Purpose of Study:. To perform a retrospective audit of the spectrum of management of tibial pseudarthrosis by a single surgeon over a seven year time period. Description of Methods:. All discharge summaries and operation logs from 2004 to 2011 were reviewed to identify patients, and their case notes and x-rays were examined. Patients were contacted telephonically for follow-up examination. Summary of Results:. Eleven patients presented with pseudarthrosis or bowing of the tibia (six females, five males, age range 4 months–7 years). Three were being treated conservatively and two patients had undergone primary below-knee amputation for severe deformity and functional deficit. Six patients had undergone resection of the pseudarthrosis with intramedullary fixation with a Williams' rod. Three of these patients had Neurofibromatosis type 1. In all instances autogenous iliac crest bone graft was used. Fibular osteotomy was performed in five of these patients and the fibula was stabilised with a K-wire in four patients. All patients were discharged in an above knee cast. Mean follow-up from 1st surgery was 23.75 (1.5–72) months. In one patient, histology confirmed suspected fibrous dysplasia. One patient had had a revision procedure 12 months prior to last follow-up for re-fracture and rod displacement. Mean residual deformity was recorded as 4.2° (1° to 10°) valgus and 6.6° (−2° to 20°) anterior bowing. We had no instances of non-union or sepsis at latest follow-up in this small series. Conclusion:. Patients with tibial pseudarthrosis have a wide spectrum of presentation. Not every patient requires immediate
INTRODUCTION. Surgical site infections (SSI) in orthopaedics are a major source of postoperative morbidity. Although perioperative antibiotic prophylaxis is a common practice, orthopaedic infections are still high in numbers, due to the increasing use of osteosynthesis material and implants. Implants are avascular and can be easily colonized with biofilm-producing germs. For both, effective prophylaxis and treatment of orthopaedic infections, the right choice of the antibiotics used, the mode of application (only systemic or systemic & local), the timing, dosage and the duration of antibiotics are of extremely high importance. Their inappropriate use does not only lead to failures in prevention or treatment of infections, but may also promote microbial resistance development and may cause serious side effects for the patients. SELECTION & USE OF ANTIBIOTICS. Prophylaxis. Broad-spectrum prophylactic antibiotics should help to eliminate the germs before they start to colonize the implant. For prophylactic purposes the recently published AAOS guidelines [1] recommend the use of cephalosporins, such as cefazolin or cefuroxim, administered within one hour prior to surgery. In cases of suspected beta-lactam allergy, clindamycin or vancomycin can be used. The latter one is also recommended in cases of MRSA colonisation. Due to extended infusion times, vancomycin should be started within two hours prior to incision. In cases of blood loss or long op duration, antibiotic administration must be repeated (e.g. cefazolin, every 2–5 hrs; vancomycin, every 6–12 hrs). There is no evidence of a benefit of continued antibiotic administration past 24 hrs of end of
Fresh-frozen allograft bone is frequently used
in orthopaedic surgery. We investigated the incidence of allograft-related
infection and analysed the outcomes of recipients of bacterial culture-positive
allografts from our single-institute bone bank during bone transplantation.
The fresh-frozen allografts were harvested in a strict sterile environment
during total joint arthroplasty surgery and immediately stored in
a freezer at -78º to -68º C after packing. Between January 2007
and December 2012, 2024 patients received 2083 allografts with a
minimum of 12 months of follow-up. The overall allograft-associated
infection rate was 1.2% (24/2024). Swab cultures of 2083 allografts
taken before implantation revealed 21 (1.0%) positive findings.
The 21 recipients were given various antibiotics at the individual
orthopaedic surgeon’s discretion. At the latest follow-up, none
of these 21 recipients displayed clinical signs of infection following
treatment. Based on these findings, we conclude that an incidental positive
culture finding for allografts does not correlate with subsequent
surgical site infection. Additional prolonged post-operative antibiotic
therapy may not be necessary for recipients of fresh-frozen bone
allograft with positive culture findings. Cite this article:
