RESUMEN
BACKGROUND: Implant removal in orthopaedics after fracture consolidation is a very common procedure but is still associated with a high rate of surgical site infection (SSI). Antibiotic prophylaxis is not recommended but advocated by some. AIM: To assess the efficacy of antibiotic prophylaxis in the prevention of early SSI following orthopaedic implant removal. METHODS: A monocentric retrospective cohort study was conducted. Patients who underwent orthopaedic implant removal procedures performed from 2016 to 2021 were included. A 1:1 propensity score matching function was used to create a cohort with matched baseline characteristics and associated risk factors for SSI. Inter-cohort comparison of the occurrence of SSI (superficial or deep) and revision surgery for SSI, after propensity score matching, was performed using the odds ratio to determine the effect of preoperative antibiotic prophylaxis. FINDINGS: In total, 965 distinct surgical procedures were included. Of these, 69 (7.15%) had an SSI, 24 (35.7%) of which required surgical revision; 214 procedures (22.18%) were performed under preoperative antibiotic prophylaxis. The propensity-matched cohort consisted of 396 procedures (198 with and without antibiotic prophylaxis). The SSI rates were 11.11% and 3.03%, respectively, in the control and antibiotic prophylaxis groups (odds ratio: 0.25; 95% confidence interval: 0.099; 0.63; P = 0.011). No difference was found for revision surgery. CONCLUSION: Preoperative administration of antibiotic prophylaxis considerably reduces the risk of SSI during the removal of an orthopaedic implant without increasing the risk of side-effects.

Rheumatoid arthritis (RA) is a polymorphous chronic inflammatory disease that is common in general population and is responsible for the occurrence of subcutaneous or visceral rheumatoid nodules. Their typical clinical presentations and localizations do not generally pose any diagnostic or therapeutic problem. We report here an atypical fistulized presentation of an unusual iliac rheumatoid nodule in a 65-year-old female patient. The evolution was favorable without recurrence at 6 months after complete surgical resection and appropriate antibiotherapy.

INTRODUCTION: Osteochondral lesions of the talus (OLT) are a frequent cause of pain in young patients and a new CT arthrographic classification system of OLT was recently proposed to help guide the choices of and standardize the indications for surgical treatment. The primary hypothesis was that this algorithm would result in a postoperative AOFAS score of ≥ 80/100. The secondary hypothesis was to identify the preoperative factors of successful surgery. METHODS: This was a prospective observational multicenter study. Eighty-six patients who underwent surgery for OLT after at least 6 months of unsuccessful conservative management were included for a mean follow-up of 15 months (12-36). Forty-nine patients with stage 1 OLT underwent microperforation, 2 patients with stage 2 OLT underwent a lift, drill, fill, and fix graft procedure with screw fixation, and 35 patients with stage 3 OLT were treated with mosaicplasty. RESULTS: After a follow-up of at least 1 year, 56 patients (65%) had an AOFAS score > 80 and the mean AOFAS score was 82 (16-100). A lower BMI (p = 0.038), a higher preoperative range of motion in the ankle (p = 0.033), higher preoperative AOFAS and FAOS scores (p = 0.001 and p = 0.011), and the presence of a preoperative bone bruise on MRI (p = 0.020) were good prognostic factors on univariate analysis. The presence of grade 1 osteoarthritis on the Van Dijk classification was predictive of a poor prognosis (p = 0.044). Multivariate analysis showed that a good preoperative range of motion (OR = 1.080 [1.020-1.150] p = 0.01) was predictive of a positive outcome, while grade 1 osteoarthritis was predictive of a poor outcome (OR = 0.147 [0.036-0.603] p = 0.008). The postoperative AOFAS decreased in six patients and 17 patients had at least one complication: six dysthesias of the superficial fibular nerve, two of the sural nerve, and nine stage 1 complex regional pain syndromes. CONCLUSION: The new algorithm for OLT resulted in a postoperative AOFAS score of ≥ 80/100 in 65% of cases. The positive predictive factors of a successful postoperative outcome were the presence of a good preoperative range of motion and the absence of preoperative osteoarthritis.

This study aimed to analyze upper-extremity combat-related injuries (CRIs) and non-combat-related injuries (NCRIs) treated in the French Forward Surgical Team currently deployed in Gao, Mali. A retrospective study was conducted using the French Military Health Service OpEX surgical database from February 2013 to March 2020. All patients operated on for upper-extremity injury were included: 224 patients, with a mean age of 28.15 years, for 249 upper-extremity injuries. Seventy-six (33.9%) sustained CRIs and 148 (66.1%) NCRIs. Multiple upper-extremity injuries and associated injuries were significantly more common in the CRI group. The majority of NCRIs involved the hand. Debridement and wound care was the most common procedure in both groups. External fixation and fasciotomy were significantly more frequent in the CRI group, and internal fracture fixation in the NCRI group. The overall number of procedures was significantly higher in the CRI group. Due to the high frequency of upper-extremity injury in current theaters of operations, deployed orthopedic surgeons should be trained in basic hand surgery so as to optimally manage both CRIs and NCRIs.

Mycetoma is a disease that occurs in the mycetoma belt, between latitudes 15Ì south and 30Ì north. It affects disadvantaged regions with limited access to medical and health facilities. Its general principles of care have changed little and are poorly known. We analyzed the management of mycetoma in Chad by French military surgeons deployed within the Epervier and Barkhane operations. This retrospective descriptive study was conducted among the cohort of Chadian patients managed by the N'Djamena forward surgical team from 2007 to 2018 as part of the medical support to the population. It includes 132 patients who had surgery for mycetoma. Surgical parameters of primary treatment and revisions procedures were analyzed. Postoperative follow-up was at least six months. Amputation was performed in 87/132 (66%) patients. Overall 11 (8.3%) required revision surgery, including 7 (5%) with eumycetoma recurrence. All recurrences occurred in the lower limb. The recurrence rate after excision was 10.2% (5/49) versus 2.3% after amputation (2/87). In the absence of effective and accessible medical treatment, surgery remains the basic treatment for mycetoma. Salvage surgery with local excision should always be considered. However, amputation is the only reliable treatment in cases with late presentation. It should not be proposed too early as limb function is preserved for a long time.

Neurogenic heterotopic ossification of the hip is secondary to neurologic lesions such as cranial trauma, stroke, medullary injury or cerebral anoxia. We shall not deal here with the other etiologies of heterotopic ossification. There are numerous locations within the hip, depending on etiology and relations with adjacent neurovascular structures are sometimes close. Preoperative work-up should include contrast-enhanced CT; scintigraphy is non-contributive. Indications for surgery are decided in a multidisciplinary team meeting, with a contract laying out expected functional gain. It is this contract that determines the extent of resection, without seeking complete resection, which would incur an increased risk of complications. The surgical approach and resection strategy depend on lesion location and any resulting neurovascular compression. The most common complications are infection and postoperative hematoma. No adjuvant treatments have demonstrated efficacy against recurrence.

"Urgent, complete, definitive" treatment still today seems to be an appropriate attitude in many trauma cases. There are, however, several situations in which emergency definitive fixation is not the optimal strategy for all cases of fracture. Temporary fixation has a role to play in the orthopedic "trauma damage control" design comprising successive steps, as applied in multiple trauma, multiple fracture, severe multi-tissue limb lesions and soft-tissue lesions of unpredictable progression. The aim of this study is to define the strategies, indications, principles and limitations of temporary fixation in limb and pelvis fracture.

BACKGROUND: The indications of osteochondral autograft implantation using the Mosaicplasty(®) technique were only recently extended to osteochondral lesions of the talus (OLT), a site for which no medium- or long-term outcome data are available. Our objective here was to evaluate medium-term outcomes in case-series of patients who underwent Mosaicplasty(®) for OLT repair. HYPOTHESIS: Mosaicplasty(®) provides good medium-term outcomes with low morbidity when used for OLT repair. PATIENTS ET METHODS: We retrospectively reviewed cases of Mosaicplasty(®) for OLT repair, performed in combination with malleolar osteotomy on the side of the OLT, at either of two centres, between 1997 and 2013. Pre-operative clinical data were collected from the medical records and all patients were re-evaluated. We studied 37 patients with a mean age of 33 years. RESULTS: Mean follow-up at re-evaluation was 76 months. Mean AOFAS score at re-evaluation was 83 (range, 9-100). A work-related cause to the OLT was associated with significantly poorer outcomes (P=0.01). AOFAS values were significantly better in patients whose OLT size was 0.5 to 1cm(2). The Ogilvie-Harris score at last follow-up was good or excellent in 78% of patients. No patient experienced morbidity related to the malleolar osteotomy. Persistent patellar syndrome was noted in 6 patients. DISCUSSION: In our case-series, Mosaicplasty(®) for OLT repair provided good medium-term outcomes in 78% of patients. Nevertheless, the donor-site morbidity should be borne in mind. Mosaicplasty(®) deserves to be viewed as a reference standard method for OLT repair. LEVEL OF EVIDENCE: IV, retrospective study.
