Aims. The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of

Between 1988 and 1995, we studied 91 club feet from a series of 120 recalcitrant feet in 86 patients requiring surgical treatment. There were 48 boys and 20 girls. The mean age at operation was 8.9 months. Surgery consisted of an initial plantar medial release followed two weeks later by a posterolateral release. This strategy was adopted specifically to address the problems of wound healing associated with single-stage surgery and to ascertain the rate of

We reviewed the long-term results of the Dillwyn Evans procedure for club foot in 60 feet of 45 patients with an average age of 29 years, using four different scoring systems. The results at 12 to 38 years were compared with those of an earlier study of the same group of patients. Function was satisfactory in 68% of feet; 90% of the patients were able to perform all desired activities. Mild residual deformity was compatible with satisfactory function, and poor function was related to ankle and subtalar stiffness. Our results suggest that this procedure has a low rate of deterioration and degenerative change with time.

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
Osteochondromas are benign chondrogenic lesions arising on the external surface of the bone with aberrant cartilage (exostosis) from the perichondral ring that may contain a marrow cavity also. In a few cases, depending on the anatomical site affected, different degrees of edema, redness, paresthesia, or paresis can take place due to simple contact or friction. Also, depending on their closeness to neurovascular structures, the procedure of excision becomes crucial to avoid recurrence. We report a unique case of recurrent osteochondroma of the proximal humerus enclosing the brachial artery which makes for an important case and procedure to ensure that no

Specific brace-fitting complications in idiopathic congenital talipes equinovarus (CTEV) have been rarely described in published series, and usually focus on non-compliance. Our primary aim was to compare the rate of persistent pressure sores in patients fitted with Markell boots and Mitchell boots. Our additional aims were to describe the frequency of other brace fitting complications and identify age trends in these complications. A retrospective analysis of medical files of 247 idiopathic CTEV patients born between 01/01/2010 - 01/01/2021 was performed. Data was collected using a REDCap database. Pressure sores of sufficient severity for clinician to recommend time out of brace occurred in 22.9% of Mitchell boot and 12.6% of Markell boot patients (X. 2. =6.9, p=0.009). The overall rate of bracing complications was 51.4%. 33.2% of parents admitted to bracing non-compliance and 31.2% of patients required re-casting during the bracing period for
Aims. To identify the minimum set of outcomes that should be collected in clinical practice and reported in research related to the care of children with idiopathic congenital talipes equinovarus (CTEV). Methods. A list of outcome measurement tools (OMTs) was obtained from the literature through a systematic review. Further outcomes were collected from patients and families through a questionnaire and interview process. The combined list, as well as the appropriate follow-up timepoint, was rated for importance in a two-round Delphi process that included an international group of orthopaedic surgeons, physiotherapists, nurse practitioners, patients, and families. Outcomes that reached no consensus during the Delphi process were further discussed and scored for inclusion/exclusion in a final consensus meeting involving international stakeholder representatives of practitioners, families, and patient charities. Results. In total, 39 OMTs were included from the systematic review. Two additional OMTs were identified from the interviews and questionnaires, and four were added after round one Delphi. Overall, 22 OMTs reached ‘consensus in’ during the Delphi and two reached ‘consensus out’; 21 OMTs reached ‘no consensus’ and were included in the final consensus meeting. In all, 21 participants attended the consensus meeting, including a wide diversity of clubfoot practitioners, parent/patient representative, and an independent chair. A total of 21 outcomes were discussed and voted upon; six were voted ‘in’ and 15 were voted ‘out’. The final COS document includes nine OMTs and two existing outcome scores with a total of 31 outcome parameters to be collected after a minimum follow-up of five years. It incorporates static and dynamic clinical findings, patient-reported outcome measures, and a definition of CTEV
Sarcomas generally metastasize to the lung, while extra-pulmonary metastases are rare. However, they may occur more frequently in certain histological sub-types. Bone metastases from bone and soft tissue sarcomas account for a significant number of extra-pulmonary disease. Resection of lung metastases is widely accepted as therapeutic option to improve the survival of oligometastatic patients but there is currently no literature supporting curative surgical management of sarcoma bone metastases. Most are treated on a case-by-case basis, following multidisciplinary tumour boards recommendations. One study reported some success in controlling bone metastases using radiofrequency ablation. Our goal was to assess the impact of curative resection of bone metastases from soft tissue and bone sarcomas on oncologic outcomes. Extensive review of literature was done to evaluate epidemiological and outcomes of bone metastases in sarcoma. We examined our prospective database for all cases of bone metastases from sarcoma treated with surgical resection between 1990 and 2016.

Antibiotic resistance represents a threat to human health. It has been suggested that by 2050, antibiotic-resistant infections could cause ten million deaths each year. In orthopaedics, many patients undergoing surgery suffer from complications resulting from implant-associated infection. In these circumstances secondary surgery is usually required and chronic and/or
Introduction. Recurrence in CTEV is not uncommon and as the child becomes older the foot in question is often stiffer and less amenable to the more traditional serial casting Ponseti method.

Background. Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children, or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severe neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has excellent functional outcome. Objective. To assess the functional outcome of acute correction of neglected Talipes-quino-varus deformity in adults. Methods. This is cross sectional, hospital–based study that took place in Khartoum, Sudan. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed to all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopaedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one years after surgery. Results. The mean age was 19.9±4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7±7.1 (poor). This score improved to 80.7±13.7 (good to excellent), two years after surgery. However, this indicates significant change in the functional outcome after the operation (P value < 0.05). Excellent post-operative functional outcome was found among patients aged 18 – 23 years 18 (50%) P. value: 0.021. The majority of patients 36(90%) were fully satisfied with the operation, 2(5%) partially satisfied and 2(5%) were unsatisfied. Conclusion. Acute correction of neglected and
Aim. Patients with late acute periprosthetic joint infections (PJI) and treated with surgical debridement have a high failure rate. Previous studies have shown that rheumatoid arthritis (RA) is an independent risk factor for treatment failure. We conducted a case-control study to identify predictors for failure in late acute PJI treatment in RA patients. We hypothesize that patients with RA have a higher failure rate compared to controls due to the use of immunosuppressive drugs. Method. Data of an international multicenter retrospective observational study was used. Late acute PJI was defined as a sudden onset of symptoms and signs of a PJI, more than 3 months after implantation. Failure of treatment was defined as persistent signs of infection,
Aim. Antibiotics have limited activity in the treatment of multidrug-resistant or chronic biofilm-associated infections, in particular when implants cannot be removed. Lytic bacteriophages can rapidly and selectively kill bacteria, and can be combined with antibiotics. However, clinical experience in patients with surgical infections is limited. We investigated the outcome and safety of local application of bacteriophages in addition to antimicrobial therapy. Method. 8 patients (2 female and 6 male) with complex orthopedic and cardiovascular infections were included, in whom standard treatment was not feasible or impossible. The treatment was performed in agreement with the Article 37 of the Declaration of Helsinki. Commercial or individually prepared bacteriophages were provided by ELIAVA Institute in Tbilisi, Georgia. Bacteriophages were applied during surgery and continued through drains placed during surgery three times per day for the following 5–14 days. Follow-up ranged from 1 to 28 months. Results. Median age was 57 years, range 33–75 years. Two patients were diagnosed with a persistent knee arthrodesis infection, one chronic periprosthetic joint infection (PJI), one cardiovascular implantable electronic device (CIED) infection and four patients with left ventricular assist device (LVAD) infection. The isolated pathogens were multi-drug-resistant Pseudomonas aeruginosa (n=3), methicillin-sensitive Staphylococcus aureus (n=4), methicillin-resistant Staphylococcus aureus (MRSA) (n=1) and methicillin-resistant Staphylococcus epidermidis (MRSE) (n=1). 4 infections were polymicrobial. 5 patients underwent surgical debridement with retention of the implant, 1 patient with PJI underwent the exchange of the prosthesis and one patient with LVAD infection was treated conservatively. All patients received intravenous and oral antibiotic therapy and local application of bacteriophages. At follow-up of 12 month, 5 patients were without signs or symptoms of infection, whereas in one patient with LVAD infection, a
Aim. Antimicrobial suppression has shown to significantly improve treatment success of streptococcal periprosthetic joint infection (PJI) compared to 12-week standard antimicrobial therapy, however, only short-term follow-up was investigated. In this study we assessed the impact of suppression on the long-term outcome of streptococcal PJI. Method. Consecutive patients with streptococcal PJI (defined by EBJIS criteria) treated 2009–2021 were prospectively included and allocated into standard and suppression (> 6 months) treatment group. Infection-free survival was assessed with Kaplan-Meier-method and compared between the groups with log rank test. Rates of infection-free, streptococcal infection-free and relapse-free status as well as tolerability of suppression were assessed. Results. Sixty-three PJI episodes (36 knee, 26 hip and one shoulder prosthesis) of patients with a median age of 70 (35–87) years were included. Twenty-seven (43%) were females. Predominant pathogens were S. agalactiae (n=20), S. dysgalactiae (n=18) and S. mitis/oralis (n=13). The main surgical procedures used were two-stage exchange (n=35) and prosthesis retention (n=21). Standard 12-week treatment was administered in 33 patients and suppression in 30 patients, of whom 10 had ongoing suppression and 20 had discontinued antibiotics at time of follow-up. Used oral antibiotics for suppression were amoxicillin (n=29), doxycycline (n=5) and clindamycin (n=2); 6 patients changed antibiotic substance due to side effects. The median follow-up time was 3.9 (0.3–13.3) years. Infection-free survival after 7.5 years was 38% with standard treatment and 62% with suppression (p=0.038). Of all failures, 52% (14/27) were due to streptococci. Suppression was effective in preventing streptococcal infection for the duration of antimicrobial treatment, however, after discontinuation
Aim. infected segmental bone defect (ISBD) is frequent in developing countries. The aim of this study was to assess the efficacy of the Masquelet technique in the treatment of ISBD in a low-resource setting. Patients and Method. We performed a prospective cohort study during the period from 2018 to 2022. Patients with infected bone defect of long bones were included. Management protocol consisted of two stages in all patients. The first stage consisted in debridement, tissues biopsy for microbiological culture, stabilization with external fixator and defect filling with gentamicin cement spacer. The second stage consisted of reconstruction using a cancellous bone autograft alone, or a mixture of autograft with allograft (demineralized bone matrix + tricalcium phosphate) and 1 gram of vancomycin powder. All patients were followed-up for at least one year. The results were assessed based on both objective (clinical and radiographic evaluation) and subjective (limb function and patient satisfaction) criteria. Main outcomes were bone union, reoperation and failure rates, union time, and limb function. Results. We included 31 patients in this study (80.6% men), with a median age of 35 [9 – 80] years. The tibia was affected in 12 cases and the femur in 15 cases. The median size of bone defect was 4 [1.5 – 12] cm. The most prevalent microorganisms were Klebsiella pneumoniae and Staphylococcus aureus. The mean interval between both stages was 14 (8 – 36) weeks and the median follow-up period after the second stage was 20 [12-62] months. External fixation was used in both stages in 25(80%) cases. Bone union was achieved in 26 (83.8%) patients of whom 24 without recurrence of infection, over a median time of 9 [6 – 16] months. All patients with a mixed graft (allograft and autograft) impregnated with local antibiotics achieved bone union. Two patients needed reoperation for
Background. Bacteriophages are natural viruses of interest in the field of PJI. A paper previously reported the PhagoDAIR procedure (use of phages during DAIR) in three patients with PJI for whom explantation was not desirable. As the need to isolate the pathogen before surgery to perform phage susceptibility testing is a strong hindrance for the development of this procedure, we developed post-operative phage injections using ultrasound, in patients infected with S. aureus and/or P. aeruginosa who were eligible for the PhagoDAIR procedure, but for whom phages were not available at the time of surgery. Materials/Methods. We performed a single center, exploratory, prospective cohort study including patients with knee PJI who received phage therapy with ultrasound after performance of a DAIR or a partial prosthesis exchange. All patients had PJI requiring conservative surgery and suppressive antimicrobial therapy (SAT) as salvage procedure. Each case was discussed in multidisciplinary meetings in agreement with French health authority, based on the clinical presentation, and the phage susceptibility testing. The cocktail of highly concentrate active phages (5 mL; about 10. e. 9 PFU/mL) was extemporaneous prepared and administered three times directly into the joint using sonography (1 injection per week during 3 weeks) during the postoperative period, before switching antibiotics to SAT. Results. Seven patients received phages under sonography after the DAIR, and one after a partial exchange (mean age 71 years). All had resection prosthesis or constrained knee prosthesis. Among these seven patients, three were infected with S. aureus (including one MRSA), two were infected with P. aeruginosa (one was a multidrug-resistant isolate), one was infected with both S. aureus and P. aeruginosa and the last one was infected with MRSA, S. epidermidis and Corynebacterium spp.. All patients received a cocktail of active phages provided by Pherecydes Pharma targeting S. aureus or P. aeruginosa. No adverse event was recorded during or after the local injections. All patients were switched to SAT after a primary postoperative antimicrobial therapy of three months. Under SAT, the patient with S. epidermidis co-infection developed a

Aim. Optimal strategies for surgical and antimicrobial management of Candida periprosthetic joint infections (PJI) are unclear. We present a retrospective case series of patients diagnosed with PJI caused by Candida spp. Method. Patients treated at our institution with Candida PJI from 01/2017 to 04/2018 were retrospectively included with isolation of Candida spp. in synovial fluid, intraoperative tissue or sonication fluid culture. PJI was defined by the proposed European Bone and Joint Infection Society (EBJIS) criteria. Treatment failure was defined as
Aim. Extraspinal osteoarticular tuberculosis (TOA-ER) is a rare form of extra-pulmonary tuberculosis. It remains a topical problem not only in underdeveloped countries but also in developed countries due to cases of immune deficiency. Through a study of 40 cases, we specify the current diagnostic aspects of TOA-ER and detail their therapeutic and evolutionary modalities. Method. The mean age of our patients was 40 years with a clear predominance of females observed (SR = 0.66). 76.31% of the cases were from a rural setting. The impairment was single-focal in 72.5%. Associated tuberculosis location was found in 59% of cases. Pain and swelling were the main clinical symptoms. Signs of tuberculous impregnation were found in less than half of the cases. The IDR was positive in 67%. All patients underwent an appropriate radiological exploration consisting of a standard x-ray (30 cases), CT (21 cases) and MRI (23 cases). technetium-99m bone scintigraphy, performed in 15 cases, detected 5 infra-clinical osteoarticular locations. 77.5% of patients had formal pathological and / or bacteriological confirmation of the diagnosis. All patients had adequate anti-tuberculosis chemotherapy with a mean duration of 18 months. 67% of patients had a surgical debridement procedure. Results. After a mean follow-up of 5 years, the outcome was favourable in 75.2% of cases. A microbiological cure at the cost of serious functional sequelae was noted in 12.8% of cases. The outcome was unfavourable with

Twelve after initial biopsy and 3 after primary R2 were submitted to chemotherapy and secondary surgery. 12/15 those resections were R0, 3/15 R1. Two of them underwent mutilating resections. Results: 11 pts are in CR. 12
Aim. Infection is one of the worst complications following total joint arthroplasty, which is often associated with significant morbidity. Currently, due to the global burden of multidrug-resistant Gram-negative bacteria (MDR-GNB) infections, few multicentre studies have described a microbiological shift from Gram-positive cocci (GPC) towards MDR-GNB PJI (prosthetic joint infection). Additionally, the emergence of MDR-GNB impacts the therapeutic options and may increase the rate of PJI treatment failure. The purpose of the present study was to describe the predisposing factors associated to failure of treatment in an orthopaedic reference hospital in Brazil from 2014 through 2019. Method. Retrospective case-control analysis of patients treated for MDR-GNB PJI over a five-year period. Data were collected from medical, surgical and laboratory records. PJI were defined according the current MSIS criteria. MDR was defined as non-susceptibility to at least one agent in three or more antimicrobial categories. Patients with PJI with at least two positive tissue cultures for MDR-GNB were selected. The control group was patient with PJI caused by multisensitive organism (GNB or GPC). Absence of signs and symptoms of infection during the follow-up period was defined as cure. Definition of failure: death, need for another course of antibiotic, or the need for another surgical procedure to control the infectious site (relapse). Results. A total of 104 patients were selected, 59 patients in the MDR-GNB PJI group and 44 in the control group. Two outcomes were compared: cure or failure. The overall 1-year survival rate was 65.3% with the median survival time being 207.08 days. In the MDR-BGN infection group the 1-year survival rate was 59.3% and the average time of survival was 141.14 days. In contrast, in the Control group the 1-year survival rate was 73.8% with an average survival time of 230.29 days (p = 0.023). HR: 2.447, IC 1.099–5.448. The independent variables in the multivariate analysis associated to treatment failure were MDR-BGN infection (p = 0.023) HR 2,447 IC 1,099 –5,448, revision surgery (p = 0.042) HR 2,027 IC: 2,027–4,061, presence of comorbidities (p = 0.048) HR 2,508 IC: 0,972- 6,469 and previous antimicrobial use in the last 3 months (p = 0.022). HR 2,132 IC: 1,096- 4,149. Conclusions. GNB-MDR PJI increases approximately 2.5 times the chance of unfavourable outcome such as death and infectious
Aim. Corynebacterium is a rare etiologic agent of BJI. We aimed to describe this rare clinical condition and to assess treatment failure determinants. Method.

After cohort description, determinants of treatment failure (i.e, infection persistence,
Aim. Our aim was to evaluate cementless one-stage revision in chronic periprosthetic hip joint infection. Method and patients. The study was performed as a multicentre, proof-of-concept, observational study with prospective data collection. Inclusion of patients with a chronic periprosthetic hip joint infection (PJI) were followed by protocolled surgical treatment (cementless one-stage revision - the CORIHA protocol) at one of 8 participating departments of orthopaedic surgery between 2009 – 2014, and the patients enrolled in a 2-year follow-up program. A PJI were diagnosed based on adopted criteria from McPherson and Zimmerli. At the time of initiation of the study in 2009, the collaborating departments performed approximately one-fourth of all nationwide primary HJR and more than one-third of all revisions. In total 56 PJI patients with a median age of 72 years and a median pre-operative ASA score of 2 met the established eligibility criteria and accepted to participate; 31 (55%) were males. The cohort had a mean follow-up time of 4.0 years, with all patients followed for minimum 2 years. The primary outcome were

Introduction: To review the medium term outcome of staged surgery for treating recalcitrant idiopathic talipes equinovarus. Methods: Between 1988 and 1995, we studied 91 club feet from a series of 120 recalcitrant feet in 86 patients requiring surgical treatment. The initial results have been reported previously and this cohort has been subsequently followed up for between 7 and 15years. The mean age at initial operation was 8.9 months. Surgery consisted of an initial plantar medial release followed two weeks later by a posterolateral release. This strategy was used specifically to address the problems of wound healing associated with single-stage surgery and to ascertain the rate of

Aims. Tenosynovial giant cell tumour (TGCT) is one of the most common soft-tissue tumours of the foot and ankle and can behave in a locally aggressive manner. Tumour control can be difficult, despite the various methods of treatment available. Since treatment guidelines are lacking, the aim of this study was to review the multidisciplinary management by presenting the largest series of TGCT of the foot and ankle to date from two specialized sarcoma centres. Methods. The Oxford Tumour Registry and the Leiden University Medical Centre Sarcoma Registry were retrospectively reviewed for patients with histologically proven foot and ankle TGCT diagnosed between January 2002 and August 2019. Results. A total of 84 patients were included. There were 39 men and 45 women with a mean age at primary treatment of 38.3 years (9 to 72). The median follow-up was 46.5 months (interquartile range (IQR) 21.3 to 82.3). Localized-type TGCT (n = 15) predominantly affected forefoot, whereas diffuse-type TGCT (Dt-TGCT) (n = 9) tended to panarticular involvement. TGCT was not included in the radiological differential diagnosis in 20% (n = 15/75). Most patients had open rather than arthroscopic surgery (76 vs 17). The highest recurrence rates were seen with Dt-TGCT (61%; n = 23/38), panarticular involvement (83%; n = 5/8), and after arthroscopy (47%; n = 8/17). Three (4%) fusions were carried out for osteochondral destruction by Dt-TGCT. There were 14 (16%) patients with Dt-TGCT who underwent systemic treatment, mostly in refractory cases (79%; n = 11). TGCT initially decreased or stabilized in 12 patients (86%), but progressed in five (36%) during follow-up; all five underwent subsequent surgery. Side effects were reported in 12 patients (86%). Conclusion. We recommend open surgical excision as the primary treatment for TGCT of the foot and ankle, particularly in patients with Dt-TGCT with extra-articular involvement. Severe osteochondral destruction may justify salvage procedures, although these are not often undertaken. Systemic treatment is indicated for unresectable or refractory cases. However, side effects are commonly experienced, and
This study sought to determine if treatment of resistant clubfeet by the Ilizarov method influenced the pattern of recurrence. Forty-seven children were identified as having undergone treatment by the Ilizarov method. Inclusion criteria for treatment with the Ilizarov method were clubfeet belonging to diagnostic categories that had recognised tendencies for resistance to standard methods of clubfoot management or a previous history of soft tissue releases performed adequately but accompanied by rapid
Objectives. The appropriate treatment for chronically infected TKR is controversial. One-stage exchange is believed to be possible only in selected cases, but the respective indications and contra-indications and the criteria of selection are not fully validated. We wanted to test the relevance of the commonly used selection criteria by comparing two groups of patients: the control group operated on with a routine one-stage exchange without selection criteria, and the study group operated on by one stage exchange on selected patients only. We hypothesized that selected one-stage exchange gives fewer failures than routine one-stage exchange procedure. Methods. We performed a retrospective study of 108 cases selected in a database of 600 patients with an infected total knee arthroplasty. The database resulted from a French multicenter trial of specialized surgeons in reference institutions, including all consecutive cases operated on between 2000 and 2010. There were 64 women and 44 men with a mean age of 69 years. All patients were followed-up for a minimal period of two years or when septic failure occurred. The patients were divided into two groups: patients operated on in a center using a routine one-stage exchange policy, and patients operated on in a center using a selected one-stage exchange policy. Patients were matched in the two groups according to body mass index and the aspect of the wound at the initial examination (one scar, several scars, presence of a fistula). The results were expressed as: free of infection,

Aim. The optimal treatment of streptococcal prosthetic joint infections (PJIs) is unclear. Poorer outcome has been associated with Streptococcus agalactiae species, comorbidities and polyethylene exchange for conservative approach. Rifampicin use may be associated with higher remission rate but results are sparse. Method. A cohort of streptococcal PJI (including total hip arthroplasty –THA- or total knee arthroplasty –TKA-) was prospectively created and retrospectively reviewed in 7 reference centers for management of complex PJI between January 1, 2010 and December 31, 2012. Results. Seventy patients (47 infections of THA and 23 infections of total TKA) with monomicrobial infections were included. Median age was 77 (interquartile range [IQR] [69 – 83], 15.6% (n=11) had diabetes, median Charlson comorbidity score was 4 [3 – 6] and 31.4% (n=22) had chronic heart failure. Streptococcus agalactiae and S. dysgalactiae were the most commonly streptococcal species found, in 38.6% (n=27) and 17.1% (n=12) of cases respectively. Debridement, antibiotic and implant retention (DAIR) was performed after a median time of 7 days [3 – 8] with polyethylene exchange (PE) performed in 21% of these treatments. After a median follow-up of 22 month [12 – 31], 27% of patients

Aneurysmal bone cysts are benign lesions of bone that tend to recur if they display an aggressive behaviour. In this study, an aggressive lesion is described as one with almost completely lost cortices on standard x-rays, mimicking ‘vanishing bone disease’. Purpose of this study is to retrospectively analyse the treatment results in this special patient subgroup. Sixteen patients with a mean age of 23.1 (6–44) were included in this study. Femur (%25) was the most commonly affected bone. Spinal lesions were excluded. All lesions were diagnosed by preoperative tru-cut biopsy, however open biopsy was also done if requested by the pathologist. All lesions were preoperatively examined by contrast enhanced MRI. They were evaluated as having almost no cortical bone rim but a periosteum like soft tissue envelope. Intraoperatively, following an extended curettage, this tissue was observed as an alive periosteal layer. Phenolisation was added and cavities were filled with allograft bone chips. The periosteum was sutured around the grafts. Additional stabilisation was performed by external fixator in 3 patients, dynamic compression hip screw in 1. Patients were followed up for a mean period of 47.8 months (9–84). Lesions healed after a mean period of 28.2 weeks (6–126). There was recurrence in 5 patients.

Purpose of study. The primary treatment of congenital talipes equinus varus with the Ponsetti method remains the gold standard of treatment. Relapsed, neglected and/or teratogenic clubfeet pose a significant treatment challenge as the long term outcome of posteromedial release surgery is poor. Advances in circular fixation offer predictable deformity correction without the need for extensive soft tissue release. The Taylor Spatial Frame utilizes the correction principles of the “Ponsetti Method”, but little literature exists describing the correction of
Introduction: Clubfoot occurs in approximately 1 in 1,000 live births and is one of the most common congenital birth defects. Although there are multiple reports of successful treatment of idiopathic clubfeet with the Ponseti method, the use of this treatment in nonidiopathic clubfeet has not been reported. This purpose of this study was to evaluate early results of the Ponseti method for the treatment of clubfeet associated with distal arthrogryposis. Methods: Twelve consecutive infants with clubfoot (twenty-four clubfeet) associated with distal arthrogryposis were treated with the Ponseti method and retrospectively reviewed. Four patients had casting treatment prior to referral. The severity of the foot deformity was classified according to the grading system of Dimeglio. The number of casts required to achieve correction was compared to published data for idiopathic clubfeet. Any recurrent clubfoot deformities or complications during treatment were recorded. All patients were followed for a minimum of two years. Results: The clubfeet of all twelve patients (twentyfour clubfeet) were graded as Dimeglio grade IV. Initial correction was achieved in all patients with a mean of 6.75 ± 0.86 casts (range, two to ten casts), which was significantly more compared to the number needed in a published cohort of idiopathic clubfeet treated with the Ponseti method (p<
0.003). Three patients (six clubfeet) had a
Aim. Pubic osteomyelitis (PO) is one of less frequent Bone and Joint Infections forms (BJI). Its management is still poorly codified as far as nosological framework is still unclear in medical literature. We aim to describe PO epidemiology and to look for factors associated with management failure. Method. We performed a retrospective cohort study, carried out in two Reference Centres, including patients with PO in 2010–2016. Treatment failure was defined by: (i) persistence of clinical signs despite treatment; (ii) clinical
Aim. Spinal infection is the most frequent complication of spine surgery. Its incidence varies between 1% and 14% in the literature, depending on various studied populations and surgical procedures. The aim of this study was to describe a consecutive 2706 case series. Method. We analyzed a prospective cohort of 2706 patients operated for spine disease between 2013 and 2016 in a University Hospital. The infection rates, germs, time between surgery and infection and outcomes after surgical revision were assessed with a minimum follow-up of 7 months. We developed a mathematical model to analyze risk factors in this difficult-to-treat population. Results. Among 2706 patient who underwent spinal surgery during the three-year study period, 106 developed a postoperative spine infection. Clinical indicators for infection were the sudden onset of local pain and swelling without fever after an initial pain-free interval. We observed a masculine predominance (68%); the median age was 56 years. The rate of infection was comprised between 0,3% (discal herniation surgery) to over 20% in posterior cervical instrumented surgery (acute cervical fractures), with a global rate of 4%. Polymicrobial infections with more than 3 germs were found in only 2 case, with 3 germs in 8 cases, 2 germs in 27 cases and 1 germ in 69 cases. Staphylococcus aureus, Propionibacterium acnes and Staphylococcus epidermidis were the three main germs identified (53, 36 and 22 respectively). Propionibacterium acnes was involved with a higher rate in instrumented surgery but also in 8% of conventional non-instrumented surgery, with a median
Aim. The incidence of hematogenous periprosthetic joint infections (hPJI) is unknown and the cases probably largely underreported. Unrecognized and untreated primary infectious foci may cause continuous bacteremia, further spread of microorganisms and thus treatment failure or
Knee extensor mechanism reconstruction after excision for bone or soft tissue tumors is a challenging procedure. When a resection of the patellar bone-tendon apparatus is required, an omologous graft can be used for its reconstruction to avoid knee arthrodesis and preserve a functional knee. Since 1996 we performed such a procedure in 15 cases in 14 patients. In 4 cases (Group 1) excision and reconstruction involved only the patella and the attached tendons together with the involved soft tissues. In the remaining 11 cases (Group 2) an extrarticular en-bloc knee resection was accomplished and reconstruction was obtained by a megaprosthesis to replace the distal femur and a composite allograft-prosthesis to replace proximal tibia and the extensor apparatus. One of the en-bloc knee resections was performed in a patient who had previously had an isolated extensor apparatus replacement, which was later converted to a complete knee resection and substitution after a local
Introduction: Congenital tarsal coalition is one of the most prevalent (1–6%) anomalies of the hindfoot and midfoot. Its etiology is unknown. By definition there are boney, cartilaginous or fibrous brigdes between 2 bones of the hindfoot and midfoot, which are classified by their localization; the most common coalitions are calcaneonavicular (53%) and talocalcaneal (37%). Patients and Methods: From 2001 to 2007 28 patients with 37 coalitions had surgery at the Orthopedic Hospital Vienna-Speising. 32 calcaneonavicular coalitions were surgically excised and an autogenous free fat graft was interponed to prevent a

In case of spine tumors, when en bloc vertebral column resection (VCR) is indicated and feasible, the segmental defect should be reconstructed in order to obtain an immediate stability and stimulate a solid fusion. The aim of this study is to share our experience on patients who underwent spinal tumor en bloc VCR and reconstruction consecutively. En bloc VCR and reconstruction was performed in 138 patients. Oncological and surgical staging were performed for all patients using Enneking and Weinstein-Boriani-Biagini systems accordingly. Following en bloc VCR of one or more vertebral bodies, a 360° reconstruction was made by applying posterior instrumentation and anterior implant insertion. Modular carbon fiber implants were applied in 111 patients, titanium mesh cage implants in 21 patients and titanium expandable cages in 3 patients; very recently in 3 cases we started to use custom made titanium implants. The latter were prepared according to preoperative planning of en bloc VCR based on CT-scan of the patient, using three dimensional printer. The use of modular carbon fiber implant has not leaded to any mechanical complications in the short and long term follow-up. In addition, due to radiolucent nature of this implant and less artifact production on CT and MRI, tumor

Aim. Negative pressure wound treatment (NPWT) has been widely adopted in the management of septic wound complications or prophylactically after large surgeries. Recent publications have indicated the necessity of further investigations to support the use of NPWT with more evidences. Therefore, the purpose of this pilot-study was to investigate the efficacy of VAC-assisted dressing systems in the treatment of septic trauma cases. Method. We analysed data of 16 retrospective cases following traumas and septic soft tissue surgeries around the hip and knee. The collected data consisted of bacterial cultures, inflammatory markers (WBC, CRP/HCRP) and body temperature, taken periodically during treatment. Also recorded were the time periods the vacuum pump was used during treatment. To increase the number of measurements and to facilitate subsequent data analysis, the measurements were interpolated to regularly sampled curves with a sampling rate of one day. We used cross-plots and linear regression analysis to investigate trends in the data: 1) while the vacuum pump was switched on and 2) while it was switched off. Results. The analysis shows that the average WBC and CRP/HCRP values decline in the first days after initiation of the VAC treatment. WBC values decline in the first four days of VAC treatment (linear regression, R. 2. =0.960). CRP/HCRP values decline in the first thirteen days (linear regression, R. 2. =0.952). No meaningful trends were observed in body temperature measurements. Importantly, there is a trend for an increase of WBC and CRP/HCRP, following the 4. th. and 14. th. days, respectively. These findings suggest that the prolonged use of VAC treatment may result in secondary

Gram-negative infections are associated with comorbid patients, but outcomes are less well understood. This study reviewed diagnosis, management, and treatment for a cohort treated in a tertiary spinal centre. A retrospective review was performed of all gram-negative spinal infections (n = 32; median age 71 years; interquartile range 60 to 78), excluding surgical site infections, at a single centre between 2015 to 2020 with two- to six-year follow-up.

Aim. Local concentration of antibiotic at the site of infection is a major parameter for its efficiency. However, bone diffusion is poor leading either to their non-use (ex: gentamicin) or the use of high concentration (ex: vancomycin). Local administration could optimize their local concentration combined with lower side effects. We report the clinical experience and pharmacological results of an antibiotic loaded porous alumina used to replace infected bone in 4 patients. Method. Two patients had a destroyed sternum following mediastinitis; one presented a femoral chronic osteomyelitis due to MRSA and one had an infected ankle arthroplasty. The ceramic was loaded with gentamicin in three cases and vancomycin for the ankle infection. Local dosages thanks to Redon's drain and blood samples were performed. Loading was done to protect the device while implanted in an infected area and was combined with conventional antibiotic therapy. Results. In comparison to pharmacological parameters: C. max. /MIC>8 for gentamicin or AUC/MIC>400 for vancomycin, local concentrations were dramatically higher than the one needed (table). Vancomycin concentration was still high after H48. Meanwhile, blood samples didn't find the presence of gentamicin during the 48 hours following implantation. After more than one year of follow-up for all the patients, there is no

The aim of this study was to gain an agreement on the management of idiopathic congenital talipes equinovarus (CTEV) up to walking age in order to provide a benchmark for practitioners and guide consistent, high-quality care for children with CTEV. The consensus process followed an established Delphi approach with a predetermined degree of agreement. The process included the following steps: establishing a steering group; steering group meetings, generating statements, and checking them against the literature; a two-round Delphi survey; and final consensus meeting. The steering group members and Delphi survey participants were all British Society of Children’s Orthopaedic Surgery (BSCOS) members. Descriptive statistics were used for analysis of the Delphi survey results. The Appraisal of Guidelines for Research & Evaluation checklist was followed for reporting of the results.Aims

Fungal periprosthetic joint infections (PJIs) are rare, but their diagnosis and treatment are highly challenging. The purpose of this study was to investigate the clinical outcomes of patients with fungal PJIs treated with two-stage exchange knee arthroplasty combined with prolonged antifungal therapy. We reviewed our institutional joint arthroplasty database and identified 41 patients diagnosed with fungal PJIs and treated with two-stage exchange arthroplasty after primary total knee arthroplasty (TKA) between January 2001 and December 2020, and compared them with those who had non-fungal PJIs during the same period. After propensity score matching based on age, sex, BMI, American Society of Anesthesiologists grade, and Charlson Comorbidity Index, 40 patients in each group were successfully matched. The surgical and antimicrobial treatment, patient demographic and clinical characteristics, recurrent infections, survival rates, and relevant risk factors that affected joint survivorship were analyzed. We defined treatment success as a well-functioning arthroplasty without any signs of a PJI, and without antimicrobial suppression, at a minimum follow-up of two years from the time of reimplantation.Aims

Sepsis following total knee replacement (TKR) is a disastrous complication. The knee arthrodesis comes as the final solution to solve the chronic infection after multiple failed surgeries. Our objective was to review these procedures performed in our institution for the past 20 years. We present a retrospective study with 5 cases of severe unsolved knee infection after TKR, who have been finally submitted to knee arthrodesis performed between 1993 and 2008. The patients are 4 males and 1 female, with a mean age of 62 years (ranging from 55 to 74 years) at the time of surgery. They presented MRSA infection (3 cases), P aeruginosa infection (1 case) and Mycobacterium tuberculosis (1 case). The average follow up was 25 months (between 12–48 months). The Visual Analogic Scale (VAS) value was registered. The mean number of surgeries before the arthrodesis was 3,6. In 4 of the 5 cases the surgeon used an external fixator to achieve the fusion. In the other patient, an intramedullary nail was used. The arthrodesis was performed in a single-time surgery in every patient. All cases achieved knee fusion and the mean time of consolidation was 5,1 months, with the longest being 8 months until fusion. No bone graft was used in any of these cases, and the mean size of leg length discrepancy was 2,8 cm. The average VAS was 3,6. In one patient with an external fixator there was a

Acute haematogenous osteomyelitis in children is relatively uncommon but delay in diagnosis and inadequate treatment can result in significant morbidity. Most recently evidence has suggested conservative treatment with adequate antibiotic therapy should be the mainstay, with provision for surgical intervention in those who fail to respond to conservative management. The outcome of primary management has been evaluated in this review. Retrospective analysis of an osteomyelitis database was conducted on individuals presenting to Auckland’s Starship and Middlemore Hospital with an ICD-10 diagnosis of Osteomyelitis between January the 1st 1999 and December the 31st 2008. 813 children fulfilled the criteria for inclusion into this review. The annual incidence of acute haematogenous osteomyelitis in the paediatric population in Auckland over this period was approximately 1:4,000. 64% were male and 36% were female. The majority were New Zealand European (35%), with the other significant ethnic groups represented being New Zealand Maori (22%), and Pacific Island (30%). 23% of patients were aged less than three. 51% of patients were between three and ten, and 26% older than ten. Only 32% had an elevated white cell count on admission. A responsible pathogen was isolated in 50% with the most common being Staphylococcus aureus, which was isolated in 77% of this group. Diagnosis was made radiologically in 66%, clinically in 27%, and surgically after exploration in 7%. The most common site of osteomyelitis was the femur in 254 individuals, followed by the tibia in 198 individuals. 49 had multi-focal involvement. Flucloxacillin was the most common antibiotic used, with 510 individuals being administered flucloxacillin at one point in time during their management. The average length of treatment was 43.7 days, which included intravenous therapy of 22.3 days, and oral therapy of 21.4 days. 60% had a range of duration of therapy from greater than three weeks through to six weeks. 44% required surgical intervention.

Osteosarcoma is the most common malignant bone tumour in children and young people. Approximately 40% patients respond poorly to highly toxic preoperative MAP (methotrexate adriamycin, cisplatin) chemotherapy with consequent inferior survival. The role of genetic polymorphisms in drug response and toxicity is reported in acute leukaemia and some solid tumours. Recent evidence in osteosarcoma suggests increased chemotherapy toxicity is associated with improved survival. The aim of this pilot study is to investigate the influence of drug target and metabolising gene polymorphisms on tumour response and chemotherapy toxicity in osteosarcoma. Patients who have completed MAP chemotherapy are eligible. Chemotherapy toxicity (CTCAE grade) is collected from patient records. Tumour response is graded as good (>
90% necrosis) or poor (<
90% necrosis) in resection specimen. Peripheral blood DNA is typed for genome-wide single nucleotide polymorphisms (SNP) using the Illumina 610 Quad array and analysed using Bead Studio software. Standard PCR techniques are used to genotype the Thymidylate synthase (TS) gene (folate pathway) for the presence of 2 or 3 copies of a 28 base pair repeat (2R/3R) and a G/C SNP in the 3R allele. 52 patients have entered to date: 33 good responders, 12 poor and 7 unevaluable for response.

Background. Fungal infection at an arthroplasty site is rare and poses a therapeutic challenge. To the best of our knowledge, no reports have been published thus far on the success rate of prosthesis reimplantation after fungal prosthetic joint infections. Questions/purposes. We asked: (1) What is the success rate in terms of infection eradication using a two-stage exchange arthroplasty in patients with hip or knee fungal periprosthetic joint infections, particularly focusing on Candida infections? (2) What patient-, infection-, and treatment-related variables are associated with the success or failure of treatment?. Methods. From January 2000 to December 2010, 16 patients with hip or knee candidal periprosthetic joint infections were treated with two-stage exchange arthroplasty at our institute. Treatment success was defined as a well-functioning joint without
Periprosthetic joint infections (PJIs) with prior multiple failed surgery for reinfection represent a huge challenge for surgeons because of poor vascular supply and biofilm formation. This study aims to determine the results of single-stage revision using intra-articular antibiotic infusion in treating this condition. A retrospective analysis included 78 PJI patients (29 hips; 49 knees) who had undergone multiple prior surgical interventions. Our cohort was treated with single-stage revision using a supplementary intra-articular antibiotic infusion. Of these 78 patients, 59 had undergone more than two prior failed debridement and implant retentions, 12 patients had a failed arthroplasty resection, three hips had previously undergone failed two-stage revision, and four had a failed one-stage revision before their single-stage revision. Previous failure was defined as infection recurrence requiring surgical intervention. Besides intravenous pathogen-sensitive agents, an intra-articular infusion of vancomycin, imipenem, or voriconazole was performed postoperatively. The antibiotic solution was soaked into the joint for 24 hours for a mean of 16 days (12 to 21), then extracted before next injection. Recurrence of infection and clinical outcomes were evaluated.Aims

Aim. This study aims to describe our department experience with single stage revision (SSR) for chronic prosthetic-joint infection (PJI) after total hip arthroplasty (THA) between 2005 and 2014 and to analyze success rates and morbidity results of patients submitted to SSR for infected THA according to pathogen. Method. We retrospectively reviewed our 10 years of results (2005–2014) of patients submitted to SSR of the hip combined with IV and oral antibiotic therapy for treatment of chronic PJI (at least 4 weeks of symptoms), with a minimum follow-up of four years (n=26). Patients were characterized for demographic data, comorbidities, identified germ and antibiotic therapy applied (empiric and/or targeted). Outcomes analyzed were re-intervention rate (infection-related or aseptic), success rate (clinical and laboratory assessment), length of stay, morbidity and mortality outcomes. Results. In this period, 26 single-stage revisions for chronic PJI of the hip were performed. Patients average age was 72 years (range 44–82). Ten patients were women. The average time of follow up was 69 months (range 4 to 12 years). The most commonly isolated bacteria were coagulase-negative Staphylococci (30%), methicillin-resistant Staphylococcus aureus (MRSA) (18%) and methicillin-sensitive Staphylococcus aureus (15%). It wasn't possible to identify the germ in 19% of the patients and other 23% were polymicrobial. Targeted antibiotic therapy was administered to 73% of patients and the most used targeted antibiotics were Vancomycin (53%), Linezolid (32%) and Rifampicin (21%). Mean length of stay was 25 days. In the follow-up period, 9 patients (35%) required a re-intervention for infection

Local recurrence (LR) following treatment of a sarcoma is generally accepted to be a poor prognostic sign and an indicator both of inadequate local control as well as of the failure of adjuvant treatment. Of 2589 patients with non metastatic Ewings, osteo-sarcoma, chondrosarcoma or a soft tissue sarcoma, 316 have developed LR at some stage following initial treatment of their tumour. 120 were already known to have metastases elsewhere when they developed LR or were found to have them at time of restaging but 196 developed LR as the first sign of
Ankle osteomyelitis after open pilon-fractures remain one of the most challenging scenarios. Ankle-fusion using an external frame is a classical option but in some cases of non-compliance patients could be not ideal. The purpose of this report was to evaluate our results using a new staged salvage protocol in cases where an external-frame arthrodesis is not recommended due to the issue of a non-compliance patient. During the first stage we resect all the infected tissues and an antibiotic-loaded cement spacer is used to obliterate the dead space, to reach some kind of stability and to achieve a high concentration of local antibiotic. A free or keystone flap is used if needed and a posterior splint is placed. After a course of targeted systemic antibiotics the second stage is schedule. During the second stage after the spacer removal, a self-made antibiotic coating retrograde hindfoot arthrodesis nail is used in order to achieve ankle fusion. We use a bone-substitute loaded with gentamicin (Cerament-G®) to fill the bone defects and to achieve high concentration of local gentamicin, to protect bone healing and to decrease the risk of
Children with spinal dysraphism can develop various musculoskeletal deformities, necessitating a range of orthopaedic interventions, causing significant morbidity, and making considerable demands on resources. This systematic review aimed to identify what outcome measures have been reported in the literature for children with spinal dysraphism who undergo orthopaedic interventions involving the lower limbs. A PROSPERO-registered systematic literature review was performed following PRISMA guidelines. All relevant studies published until January 2023 were identified. Individual outcomes and outcome measurement tools were extracted verbatim. The measurement tools were assessed for reliability and validity, and all outcomes were grouped according to the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT) filters.Aims

Incidence of Congenital talipes equino varus [CTEV] is 1 to 2 per 1000 birth, Out of all cases 20% cases are Non-idiopathic. The management of non-idiopathic CTEV, however, continues to be challenging due to Rigidity, Poor skin condition, Bony changes, Vascularity and Associated congenital abnormalities. In recent literature, short term results of Ponseti method for correction of non-idiopathic CTEV have been encouraging. As Ponseti method decreases the severity of deformity and hence decreases the need for extensive surgery. The aim of current study is to evaluate the results of Ponseti method in Non-idiopathic CTEV. Total 7 children below the age of one year with Non idiopathic clubfoot presented to us in the duration of 2013 to 2015 who were treated by us. The cases included are Streeters Dysplasia with congenital constriction rings 3, Arthrogryposis multiplex congenita with Developmental dysplasia of hip 2, Arthrogryposis multiple congenita spina Bifida 1, Pierre Robinson Syndrome with Ichthiosis 1. Initially all the patients treated with Ponseti casting technique and scoring was done using modified pirani scoring. At an average we could correct the foot from Pirani 7 to 2.5 with a

Knee joint infection after an ACL reconstruction procedure is infrequently but might be a devastating clinical problem, if not diagnosed promptly and treated wisely. The results of functional outcomes in these patients are not well known because there aren't large patient series in the literature. The objective of this study was to evaluate the prevalence and determine the adequate management of septic arthritis following ACL reconstruction and to assess the patient functional outcomes. The authors conducted a retrospective multicentric analysis of septic arthritis cases occurring after arthroscopically assisted ACL reconstructions (hamstrings and BTB), in patients submitted to surgery between 2010 to 2014. The study reviewed patients submitted do ACL reconstruction, that presented objective clinical suspicion of joint infection, in post-operative acute and sub-acute phases, associated with high inflammatory seric parameters (CRP >=10,0, ESR>=30,0) and synovial effusion laboratory parameters highly suggestive (PMN >=80, leucocytes >=3000). All this patients were treated with antibiotic empiric suppressive therapy and then directed antibiotherapy according to antibiotic sensitivity profile, then the patients were submitted to arthroscopic lavage procedure, without arthropump, but with debris and fibrotic tissue removal preserving always the ACL plasty. The functional outcomes analyzed were the Lysholm and the IKDC score. Eleven (2.2 %) out of 490 patients analyzed in the sudy were diagnosed with a post-operative septic arthritis. The microbiologic exams showed coagulase-negative Staphylococcus was present in 5 patients (S. lugdunensis in 4 cases and S. capitis in 1 case), Staphylococcus Aureus in 2 patients (1 MSSA and 1 MRSA). In four patients, the micro-organism was not identified. The studied patients had a mean follow-up of 28 ± 16 months, the Lysholm score was 74.8 ± 12.2, the IKDC score was 66.4 ± 20.5. Functional outcomes in the control group were better than those obtained in the infected group. (Lysholm score 88.2 ± 9.4 (NS); IKDC score 86.6 ± 6.8 (NS). All patients retained their reconstructed ACL. None of the patients
Prosthetic joint infections (PJI) occur in 0.8–1.9 % of arthroplasties, but the absolute number is increasing because of the frequency of procedures. Two stage exchange is the most effective strategy, but failures are often described. Culture of perioperative tissues during removal of arthroplasty is a standard procedure but culture during second step is equally important to define a success or a failure. We retrospectively reviewed PJI treated with two stage-exchange from January 2011 and December 2012 at “Ospedale S. Maria Misericordia”, Albenga-Italy. The procedure calls for bacterial culture not only during first step but also during reimplantation. Antibiotic treatment is prolonged after reimplantation until the cultures availability. A failure was defined by persistence of infection for positive culture or reocurrence of infection during a follow up of at least 2 years in patients with negative cultures. Three positive cultures yielding phenotypically identical organisms, or a single specimen of a virulent microorganism (e.g. Staphylococcus aureus) were required to rule out false positive for contaminants. Patients with persistence of infection were treated for 3 months with antibiotics. 86 patients underwent the two stage treatment: 45 hip and 41 knee prosthesis. The average ESR before arthroplasty removal was 59 mm/ 1st h (range 5–120), the average CRP was 3.9 mg/dl (range 0.3 – 34). Coagulase-negative staphylococci were isolated in 31 cases, Staphylococcus aureus in 19, Streptococcus spp in 8 and enterococci in 4. Gram-negatives were isolated in 4 patients and polymicrobial infection in 6 patients. In 14 patients (16%) no pathogen was identified. A positive culture during reimplantation was documented in 11 (13%) cases: 8 coagulase-negative staphylococci, 2 Staphylococcus aureus, 1 Candida sp. All patients received 3 months of therapy after surgery and 6 of them were free of infection at 2 years of follow up after the end of treatment. Among the 75 patients with negative cultures, a
Purpose: Desmoid tumours are uncommon in the axillary region. We report the clinical course in seven patients operated for desmoid tumours of the axillary region. Material and methods: Our series included two women and five men. Mean age was 52 years (39–60). One tumour was in the trapesium, two were in the retroplexic, two in the axillary fossa, one in the deltoid and one in the upper part of the arm. Biopsy and magnetic resonance imaging were obtained in all patients. Surgical margins were in healthy tissue in five cases; resection was limited to intratumoural tissue in one. The axillary nerve had to be sacrificed in two patients, the spinal nerve in one and the medial nerve in one. Chemotherapy was given to one patient prior to surgery. Results: Mean follow-up was 51 months (23.2–162.1). Five patients experienced at least one
Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set. A total of 11 databases were searched. A subset of studies published between 1 October 2020 and 1 January 2011 from a larger review mapping research on limb reconstruction and limb amputation for the management of lower limb COM were eligible. All outcomes were extracted and recorded verbatim. Outcomes were grouped and categorized as per the revised Williamson and Clarke taxonomy.Aims

The initial treatment of the congenital clubfoot is still a debated subject among different schools. We report our current experience with Ponseti method. Materials and Methods: From April 1999 to May 2001 we have consecutively treated with this method 80 idiopathic clubfeet of 57 children put under treatment at neo-natal period. Progressive correction of the deformity has been obtained with 7 toe-to-groin plaster casts changed weekly. When complete derotation of the hind-foot and forefoot has been reached, subcutaneus tenotomy of the tendon Achilles has been performed. At the end of this first period, the feet have been adapted in Denis Browne splint, worn full time for four months and thereafter just at night. The feet have been evaluated clinically (score of Dimeglio and Bensahel), radiologically and some with MRI. Results: Whole correction of the deformity at the end of treatment with plaster casts, has been achieved for 71 times. When the plaster casts are removed, the talocalcaneal divergence, on antero-posterior and lateral views and the tibial-calcaneal angle (x-ray in maximum dorsal flexion ), were respectively, as an average of 20; 30,7; 21,9 degrees. At an average of 20 months follow up, 54 feet of 80 had a score of 0 or 1 of 20, and 14 had a score of 2; on radiological aspect the talo-calcaneal divergence in antero-posterior and lateral views and the tibial-calcaneal angle were respectively as an average of 29; 24,5; 14 degrees. At this evaluation the percentage of
Purpose: Benign giant-cell tumours of the lower radius constitute a therapeutic challenge. Curettage with bone graft is generally used, but in this localisation recurrence varies from 25% to 80% requiring repeated surgery with a high risk of losing function. Material and methods: Eight patients (five men and three women), aged 27 to 59 years were treated by our team between 1972 and 1994. Primary care was given in our unit for six of them and two others were referred for secondary surgery after recurrence. Radiographically, five of the tumours were aggressive (two had already led to fracture) and three were progressing. Three patients were treated first by curettage and bone graft to fill the gap. For the five other patients treatment included enucleation, curretage, and cement filling followed by osteosynthesis and immediate mobilisation. All patients were followed regularly at visits every three months for two years then every six months for two more years and every year thereafter. Median follow-up was 15 years (six–25 years). Results: There were 12 recurrences (including four in soft tissue) in five patients (three patients initially treated with bone filling and two others among the five treated with cement filling). Recurrence was noted six to 30 months after surgery. Two patients initially treated with bone filling later had an arthrodesis that was filled with cement. Patients whose gap had been filled with cement and who had recurrence were treated again with cement filling. At last follow-up, all patients were in remission but two of them had lost wrist mobility. According to the function criteria established by the European Society for Bone Tumours, the final functional result was excellent in five, good in two and fair in one. Patients treated with cement filling had wrist mobility comparable to the healthy side and did not exhibit any radiographic alteration of the joint line. Conclusion: The risk of
