ABSTRACT
BACKGROUND: Amniocentesis is the most performed invasive prenatal diagnostic procedure. Learning the procedure is difficult for the learner, the teacher and the patient because of the risks inherent to this technique and the anxiety generated by the procedure. The objective of this work was to evaluate a theoretical and practical amniocentesis training workshop using a simulator. METHODS: We were inspired by Pierre Jean's precepts for the planning of a medical training. We then carried out the pedagogical session with the gynecology residents of our Regional University Hospital, a type 3 maternity hospital in France. We evaluated the theoretical learning through a questionnaire before and after the training and then the practical session on a home-made simulator. The satisfaction of the participants was assessed by a questionnaire at the end of the session. RESULTS: Fifteen learners, from the first to the last semester of internship, participated in the training. The median score of the pre-training questionnaire ("pre-test" questionnaire) was 3.3 out of 10 (min = 1, max = 6) and that of the post-training questionnaire ("post-test" questionnaire) was 7.9 out of 10 (min = 6, max = 9). The post-training scores were significantly higher (p < 0.0007). The average score for the practical training was 30.5 out of 40 (24-36). 93 % of the learners were fully satisfied with the theoretical training and 100 % stated that they had improved their technical skills. CONCLUSION: The residents in our department expressed a need for training in this invasive procedure of antenatal diagnosis. The training proved to be beneficial following the evaluation of the learning but also following the feedback of the learners.

BACKGROUND: Surgical site infections (SSIs) are the second most common healthcare-associated infection. Active SSI surveillance can help inform preventative measures and assess the impact of these measures. AIM: We aimed to describe the evolution in trends over 14 years of prospective active SSI surveillance and implementations of SSI prevention measures in a French Teaching Hospital. METHODS: We monitored and included in the study all surgical procedures performed from 2003 to 2016 in eight surgical units. The semi-automated surveillance method consisted of weekly collection of SSI declaration forms (pre-filled with patient and procedure administrative data and microbiology laboratory data), filled-in by surgeons and then monitored by the infection control practitioners. FINDINGS: A total of 181,746 procedures were included in our analysis and 3270 SSIs recorded (global SSI rate 1.8%). The SSI rate decreased significantly from 3.0% in 2003 to 1.1% in 2016. This decrease was mainly in superficial SSIs and high infectious risk procedures. Higher SSI rates were observed for procedures associated with the usual risk factors. During this 14-year period, several evolutions in surgical practices occurred that might have contributed to this decrease. CONCLUSIONS: With an overall decrease in SSI rate throughout the surveillance, our results revealed the benefits of an active and comprehensive hospital SSI surveillance programme for understanding the SSI rate trends, analysing local risk factors and assessing the effectiveness of prevention strategies. These findings also highlighted the importance of the collaboration between surgeons and infection control practitioners.

Bertolotti's syndrome is a little-known and little-discussed pathology. We report the case of a 13-year-old child diagnosed with Bertolotti's syndrome after several years of functional complaints. Conventional radiography was used to diagnose the transverse mega-apophysis of L5, while sectional and functional imaging confirmed a lumbosacral-iliac impingement. In view of the transient efficacy of medical management, surgical resection of the transverse mega-apophysis was performed. The medium-term decline in symptoms was excellent and the patient resumed physical activities without limitation or pain.

PURPOSE: The intramedullary percutaneous pinning in fractures of the lateral malleolus is a technique of osteosynthesis that can reduce complications of ORIF. Our study describes the morphology and the morphometry of the fibula, in particular intramedullary, so as to specify the best fibular nail features. METHODS: We conducted a retrospective study on CT acquisitions of fibulae in vivo. We studied total length, and the distal malleolar angle. Regarding intramedullary morphology, six axial study levels were defined. Each level was assigned a morphometric classification (oval, triangular, quadrangular or irregular), and a measure of the diameter of the cavity. The distance between the smaller diameter and the malleolar tip was investigated. RESULTS: We included 50 patients for 97 fibulae. The average age was 66.5 years. The irregular morphology type was the most frequently found. The average length was 370.5 mm (SD = 18.1; CI 95% [366.9; 374.1]), the average distal malleolar angle was 163.5° (SD = 3.7; CI 95% [162.7; 164.2]). The average minimal intramedullary diameter at malleolus level was 3.2 mm (SD = 1.2; CI 95% [3.0; 3.5]), with a minimum size reaching 95.8 mm (SD = 13.8; CI 95% [93.0; 98.5]) of the malleolar tip. CONCLUSIONS: The analysis of morphological parameters of the fibula, in particular the lateral malleolus and intramedullary morphology is necessary for the design of a morpho-adapted nail. Interpersonal variability must be taken into account by the implant industry to offer nails of suited lengths and diameters.

A case of post-traumatic lower-limb pyoderma gangrenosum (PG) in a 77-year-old female is reported. The diagnosis of PG is frequently one of exclusion, and it is therefore unsurprising that the condition was initially mistaken for necrotising fasciitis then for necrotising bacterial dermo-hypodermitis. Medical and surgical treatment for those conditions proved ineffective. This fact, together with the atypical presentation, promoted a re-evaluation of the diagnosis. The clinical findings and investigation results converged to suggest PG, and a therapeutic trial was initiated. The good treatment response and negative findings from tests for other conditions established the diagnosis of post-traumatic PG.

INTRODUCTION: Simulation for arthroscopy helps surgical trainees develop their surgery skills in a safe environment. This teaching technique has become more widespread in recent years because of the need to provide surgeons in training with an alternative to the current methods. We hypothesized that a resident in surgery could acquire the skills needed to perform arthroscopic shoulder surgery by working on a simulator. MATERIAL AND METHODS: The study was conducted over a 4-month period from June to September 2016. All the surgeons and residents in our department participated in the study. We recorded each participant's age, sex, dominant hand, and video gaming experience. We used the Arthro Mentor™ simulator from Simbionix (now 3D Systems). Testing was carried out at the start and end of training to evaluate the participant's skills and their progression. The changes were evaluated statistically. RESULTS: Fourteen surgeons were included in the study. They were split into two groups: controls and residents. There was a statistically significant improvement in the intern group between the overall pre-test score and the overall post-test score. There was no significant improvement in the overall score of the control group between the pre-test and post-test. DISCUSSION: For surgeons in training, shoulder arthroscopy simulation helps them acquire the skills needed to perform arthroscopy such as hand-eye coordination, triangulation and the ability to work in three-dimensions based on two-dimensional visual information. We believe that the benefit of simulation resides in learning the skills needed to perform a surgical procedure, not in learning the procedure itself. LEVEL OF EVIDENCE: III-case-control study.

Diffuse giant cell tumours of the tendon sheaths are described in the literature as locally aggressive soft-tissue tumours. We report the case of a 56-year-old male with a history of multiple surgical procedures for a giant cell tumour of the fibular tendon sheath at the right ankle. The multiple recurrences prompted monitoring by positron-emission tomography, which showed lung tumours. Biopsies confirmed that the tumours were metastases from the giant cell tumour of the tendon sheath. In patients with recurrent and/or diffuse giant cell tumour, positron-emission tomography is an effective monitoring tool.

Consensus opinion is that active movement of the elbow is a priority in the surgical treatment of total brachial plexus injuries. But the indications and neurotization techniques used to restore motor function of the hand are the subject of discussion. The aim of this retrospective study was to evaluate, in adult patients with complete post-traumatic paralysis of the brachial plexus, the functional results of neurotization of four intercostal nerves on the musculocutaneous nerve and grafting of the C5 root by one strand on the nerve to the long head of triceps and three strands on the medial component of the median nerve. The cohort included 21 patients (mean age 21years). The average time between the trauma and surgical treatment was 4.8months. At a mean follow-up of 22months, 67% of patients achieved≥M3 elbow flexion, and 62% achieved≥M3 active elbow extension. Of the patients who had the required follow-up of 2years to assess motor recovery of the median nerve, 40% achieved function≥M3. Based on our results, use of the C5 root is suitable for surgically restoring elbow extension and finger flexion.

INTRODUCTION: Adult forearm fractures account for 1-2% of all fractures of the limbs. The main objective of this retrospective multicenter study was to evaluate pre- and postoperative complications of forearm fractures. The secondary objective was to evaluate functional and radiological results of plate osteosynthesis for these fractures. MATERIAL AND METHODS: Between January 2008 and March 2014, 131 forearm fractures were reviewed retrospectively. Fractures were classified preoperatively according to the AO classification. Clinical outcomes were classified into four categories according to the Tschnerne and Oestern classification. Pre- and postoperative complications were sought systematically. RESULTS: Before surgery, 12 patients had neurological impairment (9%). At the last follow-up, nine patients had persistent neurological disorders (6.9%). Union of forearm fractures was obtained in 122 patients at 4.6 months on average (±2.6). Nine patients with nonunion were observed (6.9%) and five patients had radioulnar synostosis (3.8%). DISCUSSION: The frequency of neurological complications concomitant to forearm fractures is noteworthy. Similar cases with essentially irritative neurological disease have been reported in the literature, in particular for the ulnar nerve. Fracture nonunion is a relatively common complication: between 2 and 10% of cases depending on the study. LEVEL OF EVIDENCE: IV.

BACKGROUND: Ulnar nerve entrapment at the elbow is the second most common nerve entrapment syndrome at the upper limp, after carpal tunnel syndrome. Many surgeons feel that ulnar nerve instability contra-indicates endoscopic nerve release. Published studies, however, found no evidence that pre-operative or intra-operative ulnar nerve instability adversely affected clinical outcomes. The objective of this prospective study was to define the indications and describe the outcomes of endoscopic ulnar nerve release at the elbow. HYPOTHESIS: Endoscopic ulnar nerve release at the elbow is a valid option even in patients with ulnar nerve instability and regardless of the severity of the compression. MATERIAL AND METHODS: We conducted a prospective single-centre study of patients scheduled for surgery based on clinical and electromyographic manifestations of ulnar nerve entrapment at the elbow. Ulnar nerve instability (incomplete dislocation, i.e., Childress A) before or during surgery was not a contra-indication to the procedure. The patients were re-evaluated 12 months after surgery. RESULTS: Seventeen patients were included in the statistical analysis. The modified Bishop's score indicated excellent or good outcomes in 15 (88%) patients (excellent in 4 and good in 11) and a fair outcome in 2 patients. Functional outcomes were not associated with the presence of ulnar nerve instability before surgery. DISCUSSION: We elected to include patients with Childress A ulnar nerve instability. Clinical outcomes in these patients were similar to those in patients without ulnar nerve instability. LEVEL OF EVIDENCE: IV, open prospective study of treatment outcomes.

In elderly patients, distal radius fractures are often associated with osteoporotic bone. Under these conditions, anatomic resurfacing implants may provide satisfactory results in terms of range of motion, pain and function. Between July 2009 and January 2012, eight elderly patients were treated with the SOPHIA™ implant at our hand surgery department. Inclusion criteria were isolated comminuted distal radius AO type C2 fractures in patients greater than 70 years of age. All patients were reviewed in February 2013 by an independent surgeon. Clinical, functional and radiographic assessments were performed. Mean follow-up was 25 months (range 17-36 months). Mean ROM was 45° (range 40-50°) in flexion and 44° (range 40-50°) in extension. Mean pronation-supination range was 160°. Mean grip strength was 18 kgf. Mean Quick DASH was 18.2/100 (range 6.82-29.55) and mean pain on VAS was 2.33 (range 0-4). X-rays did not reveal any implant loosening or ulnar translation of the carpus. Use of a wrist resurfacing implant led to rapid recovery of autonomy in elderly patients with comminuted distal radius fractures. It parallels the use of shoulder or elbow prostheses for complex joint fractures in the elderly.

Dislocation is a major complication of total hip arthroplasty (THA), whose frequency has been unaffected by improvements in surgical techniques and implants. The dislocation rate depends on multiple factors related to the patient, hip disease, and surgical procedure and is therefore also dependent on the surgeon. The many published studies on THA dislocation, its causes, and its treatment have produced conflicting results. The objective of this work is to review the management of THA dislocation, which is a severe event for both the patient and the surgeon. This lecture starts with a brief review of data on THA dislocation rates and the many factors that influence them. Emphasis is then put on the evaluation for a cause and, more specifically, on the challenges raised by detecting suboptimal cup position. Next, reported techniques for treating THA dislocation and the outcomes of each are discussed. Finally, a management strategy for patients selected for revision surgery is suggested.

Among soft tissue tumors, nodular fasciitis is a relatively common tumor process, which occurs in the 30 first years of life. Nodular fasciitis is a benign tumor with a rapid proliferation of myofibroblastic cells, which develops at the expense of a muscular fascia in the subcutaneous tissue. Usual localizations are the trunk and upper limbs. Difficulty of diagnosis consists in the need to eliminate many differential diagnoses especially malignant tumor processes. From a clinical point of view, the rapid development of nodular fasciitis (from some days to some weeks) must fear a malignant process. This benign lesion, which does not recur (even if incomplete resection), may regress spontaneously. We report such a tumor located at the cubital fossa confirmed by a pathological examination.

INTRODUCTION: The reference surgical treatment for unstable posterior pelvic fracture is percutaneous iliosacral screw fixation, isolated or in association with other techniques. As there is a risk of passage outside the bone when performing screw fixation under fluoroscopy, new image-guidance techniques have been developed: fluoronavigation, peroperative 3D navigation, CT-linked navigation, etc. Since September 2011, our department has performed iliosacral screw fixation under CT control linked to navigation so as to optimize screw positioning. This innovative technology has been used in neurosurgery in our center since 2007, for disc implants, spinal fracture, vertebral arthrodesis and intracerebral localization. MATERIAL AND METHODS: Six patients were treated by iliosacral screw fixation for posterior pelvic ring fracture lesion. The O-ARM (Medtronic(®)) computer-assisted surgical navigation system was used, combining surgical navigation and peroperative 3D imaging. This kind of osteosynthesis is suitable for non-displaced or prereduced fracture. A radiation dose report is drawn up at end of surgery. DISCUSSION: Postoperative course does not differ from other percutaneous osteosynthesis techniques, combing the advantages of a percutaneous approach (reduced infection and blood-loss rates, etc.) while optimizing iliosacral screw positioning. To date, no radiation overexposure has been found. CONCLUSION: The precision and safety of iliosacral screw fixation are now unequalled, meeting the basic computer-assisted surgery principles of reduced morbidity without overexposure to ionizing radiation. Indications for computer-assisted surgery should therefore be extended to iliosacral pathologies (arthritic, tumoral and inflammatory), non-displaced acetabular fracture, etc.

Trichilemmal cyst is a benign tumor, developed from hair follicle, located mainly at the scalp. We report a clinical case of unusual location at the finger pulp confirmed by histology. The main differential diagnosis in this reported case was a whitlow. The origin of this cyst is probably the nail matrix whose keratinization is trichilemmal. Surgical excision biopsy allowed a good clinical outcome.

UNLABELLED: Surveillance of surgical site infections (SSI) is a priority. One of the fundamental principles for the surveillance of SSI is based on receiving effective field feedback (retro-information). The aim of this study was to report the results of a program of SSI surveillance and validate the hypothesis that there is a correlation between creating a SSI surveillance program and a reduction in SSI. MATERIALS AND METHODS: The protocol was based on the weekly collection of surveillance data obtained directly from the different information systems in different departments. A delay of 3 months was established before extraction and analysis of data and information from the surgical teams. The NNIS index (National Nosocomial Infections Surveillance System) developed by the American surveillance system and the reduction of length of hospital stay index Journées d'hospitalisation évitées (JHE). RESULTS: Since the end of 2009, 7156 surgical procedures were evaluated (rate of inclusion 97.3%), and 84 SSI were registered with a significant decrease over time from 1.86% to 0.66%. A total of 418 days of hospitalization have been saved since the beginning of the surveillance system. DISCUSSION: Our surveillance system has three strong points: follow-up is continuous, specifically adapted to orthopedic traumatology and nearly exhaustive. The extraction of data directly from hospital information systems effectively improves the collection of data on surgical procedures. The implementation of a SSI surveillance protocol reduces SSI. LEVEL OF EVIDENCE: Level III. Prospective study.

INTRODUCTION: Distal humerus condyle fracture in children is rare. These fractures often mislead the emergency physician or surgeon. However, treatment adapted to the degree of displacement achieves excellent clinical and radiographic results. The objective of this study was to clarify indications for conservative treatment of lateral humeral condyle fracture in children. MATERIALS AND METHODS: Twenty-two children who had sustained lateral humeral condyle fracture between January 2007 and January 2010 were reviewed in April 2010. At this consultation, the children underwent clinical and radiological examination. The Hardacre functional score was used to determine objective clinical outcome. RESULTS: Conservative treatment was exclusive to cases of lateral condyle displacement equal to or less than 1mm. All other fractures were managed by surgical open reduction and fixation using cross-pinning. There was no statistically significant difference in clinical or radiological outcome between conservative and surgical management. DISCUSSION: Lateral humeral condyle fracture is difficult to diagnose in children. The majority of poor results reported in literature relate to inadequate initial treatment. Given a radiological aspect of hemarthrosis of the elbow, the emergency physician prescribes multiple X-ray views of the affected elbow (anteroposterior, lateral and internal oblique). The clinical aspect of lateral humeral condyle fracture is often characteristic (ecchymosis facing the head of the radius). Nondisplaced or minimally displaced lateral humeral condyle fracture can be managed conservatively under close survey. However, secondary displacement under the cast is often difficult or impossible to detect, and outpatient surgery is therefore being increasingly indicated in our department.

INTRODUCTION: Arthroscopically assisted percutaneous internal fixation has found its place in the treatment of Schatzker I-III tibial plateau fractures, with good short-term results reported. The objective of this study was to observe the progression of osteoarthritis at the medium term through clinical and radiological assessment. PATIENTS AND METHODS: Twenty-seven patients were treated with arthroscopy-assisted percutaneous fixation for stage I-III Schatzker tibial plateau fractures. RESULTS: Twenty-one patients were reviewed with a mean follow-up of 59.5 months (range, 24-138 months); satisfaction was good except for return to sports activity. The mean IKS score was 85.2 for the knee score and 91 for function. The mean Lysholm score was 86 points, with a mean Tegner activity score of 4. A mean score of 25.5 and 8 points was found for the clinical and radiological Rasmussen scores, respectively; 47.6% of the patients presented early osteoarthritis on radiological evaluation. DISCUSSION: The medium-term functional results were comparable to the short-term results. The patients were satisfied except for return to sports activity. Age at surgery appears as a prognostic factor for osteoarthritis. CONCLUSION: Arthroscopic internal fixation remains the technical reference for Schatzker I-III tibial plateau fractures despite the appearance of osteoarthritis, which remains less extensive than in open surgery. LEVEL OF EVIDENCE: Level IV. Retrospective study.

INTRODUCTION: Anterior dislocation of the shoulder is frequent, with high rates of recurrence. Immobilization in external rotation (ER) seems to improve results, although few studies have actually demonstrated this. The present MRI study examined the impact of ER on labral and capsular ligamentous complex lesions after primary dislocation. MATERIAL: A prospective study was started up on January 1st, 2007. Inclusion criteria were: acute initial anteromedial dislocation of the shoulder, without past history of shoulder trauma. There were 23 such patients, with a mean age of 37 years. METHODS: Early MRI scan used the following protocol: one acquisition in internal rotation followed by one in ER. Study criteria were: hemarthrosis, ER amplitude, rotator cuff status, bone lesion, and labral lesion stage (Habermeyer's classification) and displacement (Itoi criteria). RESULTS: There were 12 right and 11 left shoulders. Mean time to MRI was 3.7 days. There were three rotator cuff tears, no glenal lesions, and 14 humeral notches. Hemarthrosis was almost systematically present, with its distribution modified by ER in 75% of cases; three patients showed no posterior hemarthrosis, in whatever rotation. Mean ER was 37 degrees. On Habermeyer's classification, there were 12 stage-1 lesions, and 10 stage-2; one patient had no labral lesion. All separated labra were reduced in ER, five (21%) totally. In six cases, labral displacement changed according to rotation. All anterior joint effusion was reduced in ER, in three cases totally. DISCUSSION: According to Itoi among others, immobilization in ER is the way to reduce recurrence of anterior dislocation. The present study confirmed that labral reduction was systematic with ER, but it was by no means always complete. ER seemed more effective in reducing the separation. Results further confirmed that ER reduced anterior capsule volume, a recurrence factor. CONCLUSION: ER reduced hemarthrosis, anterior capsule detachment and labral lesions, and never the contrary. The interest of immobilization in ER to prevent shoulder instability needs confirming by long-term clinical studies; we are therefore extending the present MRI study by a clinical study of ER immobilization in all patients showing significant labral lesion reduction. LEVEL OF EVIDENCE: Level IV. Retrospective therapeutic study.

We randomized 103 patients over the age of 50 with an unstable closed intra- or extra-articular dorsally displaced distal radius fracture to have either palmar fixed-angle plating (n=50) or 'mixed pinning' (n=53) and compared the clinical and radiological outcomes at 3, 6, 12 and 26 weeks after surgery in a prospective study. Postoperative palmar tilt was significantly better in those stabilized with K-wires, but loss of reduction was statistically less in those stabilized with a plate. At 26 weeks, functional results, assessed by DASH and Herzberg scores, were better in those fixed with a plate.
