RESUMO
PURPOSE: To compare the efficacy of embolization with imipenem/cilastatin and microspheres in chronic shoulder pain. METHODS: This retrospective study included 29 patients who underwent embolization for chronic shoulder pain between June 2017 and March 2022 with calibrated MSs from 100 to 250 µm or IMP/CS. The main objective was the clinical success evaluated by the Minimum Clinically Important Difference (MCID) at 3 months after the procedure, validated if the patient responded yes to 2 questions: (1) Is the pain less severe than before the procedure? (2) Are you satisfied with the procedure? The decrease in visual analogue pain scale scores and the safety of the procedure were evaluated. RESULTS: Embolization was achieved in all patients. In the MS group, 4/15 patients (26.7%) experienced clinical success at 3 months according to MCID versus 10/14 patients (71.4%) in the IMP/CS group (p = 0.02). The mean VAS decreases were respectively - 28.6% ± 34.6 in the MS group and - 36.8% ± 27.8 in the IMP/CS group at 1 month (p = 0.50), - 29.9% ± 29.0 and - 39.6% ± 23.0 at 3 months (p = 0.33) and - 30.6% ± 32.8 and - 46.6% ± 28.4 at 6 months after the procedure (p = 0.26). Eleven patients (73.3%) in the MS group and 3 patients (21.4%) in the IMP/CS group had complications (p = 0.01). Among them, 2/15 patients (13.3%) had transient skin ischaemia in the MS group. CONCLUSION: Embolization with IMP/CS may be more effective and safer than MSs in the management of chronic shoulder pain.

PURPOSE: Musculoskeletal (MSK) embolization is emerging in tendinopathy treatment. The objective of this study was to assess the efficacy and safety of MSK embolization with microspheres in the treatment of chronic shoulder pain. PATIENTS AND METHODS: This retrospective monocentric study included patients with chronic shoulder pain resistant to 6 months or more of conventional therapies who were treated with MSK embolization between 2017 and 2021. Embolization was performed using calibrated 100-250 µm microspheres. Clinical success was defined as pain reduction, i.e., a decrease in the visual analogue scale (VAS) pain score of ≥50% at 3 months after MSK embolization as compared to baseline. Adverse events were collected. RESULTS: Fifteen patients (11 women, 4 men) were included, with a median age of 50.3 years (IQR: 46.7-54.5). The median duration of symptoms was 26.6 months (20.6-39.8). The median VAS pain scores were 7.0 (7.0-8.0) at baseline, 6.0 (3.5-7.0) at 1 month, 5.0 (4.5-6.5) and 5.0 (3.0-7.4) at 3 months and 6 months (p = 0.002). Three patients (20%) reported clinical success at 3 months. Three patients experienced minor complications after embolization (paresthesia, n = 2; transient osteo-medullary edema, n = 1) and two patients had moderate complications (transient skin ischemia). CONCLUSION: MSK embolization with microspheres for treatment of refractory chronic shoulder pain showed moderate results in terms of clinical success and safety.
RESUMO
Sprains of the first metacarpo-phalangeal joint (MCPJ) are a common form of hand injury that mainly affects the ulnar collateral ligament. Although the diagnosis is made on the physical findings, radiographs must be obtained and ultrasonography or magnetic resonance imaging (MRI) is necessary in some cases. If the joint is unstable or a bony fragment is displaced, surgery must be performed within 4 weeks after the injury. Beyond this interval, ligament reconstruction is the preferred treatment. The objective of this article is to provide evidence, from both older and recent studies, that guides the choice of the best treatment in clinical practice. To this end, we will address the following questions: (1) What is a Stener lesion? (history and pathophysiology); (2) In addition to the physical examination, what other investigations are appropriate in doubtful cases? (with special attention to the indications of ultrasonography and MRI); (3) What are the clinical and radiological criteria for performing surgery in patients with acute first MCPJ sprains? (4) What reconstruction procedures are appropriate in patients with acute or chronic MCPJ sprains?

INTRODUCTION: Certain structures and pathologies can be difficult to reveal under videoscopy alone during arthroscopic surgery. Ultrasound can be a useful contribution in arthroscopic diagnostic and therapeutic procedures. The main aim of the present study was to assess equivalence between endoscopic and external ultrasound for shoulder exploration. Secondary objectives comprised qualitative assessment of endoscopic ultrasound images and comparative assessment of acquisition time between the two techniques. MATERIAL AND METHODS: An anatomic non-inferiority study was conducted on 6 shoulders from 3 subjects with a mean age of 84 years. After ultrasound examination by a radiologist specializing in osteoarticular imaging, shoulder arthroscopy was performed by a single specialized surgeon, using an ultrasound endoscope. Number of visualized structures and image quality were assessed by independent observers. RESULTS: Ten of the 11 structures of interest (91%) were visualizable on endoscopic ultrasound, versus 4 (36%) on external ultrasound (p<0.05). Mean endoscopic acquisition time was 9.5±6.3minutes [range, 5;22]. In the 11 structures, image quality was better on endoscopic than external ultrasound, except for the acromioclavicular joint, where quality was better on external ultrasound, and the lateral side of the rotator cuff, where quality was equivalent. CONCLUSION: The present study demonstrated equivalence between endoscopic and external ultrasound for shoulder exploration. LEVEL OF EVIDENCE: IV, Non-inferiority cadaver study.

INTRODUCTION: Reverse shoulder arthroplasty (RSA) has become a common treatment in displaced proximal humeral fracture (PHF) in elderly patients due to inconstant results with osteosynthesis or hemiarthroplasty. RSA allows a good anterior elevation but rotational results are more random and depend on tuberosity healing. HYPOTHESIS: Use of an offset modular system (OMS) on the prothesis improve tuberosity healing and functional results. MATERIAL AND METHODS: This retrospective cohort analysed radiological and clinical outcomes at least one year after the use of RSA Humelock II Reversed (Fx Solutions) after a displaced PHF Neer 3 or 4 in patients over 70 years. The first criterion was tuberosity healing with or without the use of the OMS device on radiographs. The second criterion was a clinical analysis of active range of motion (ROM), anterior elevation (AAE), external and internal rotations (ER, IR), Constant, DASH, SSV, VAS scores according to tuberosity healing. We also analysed radiological and clinical complications. RESULTS: We analysed from November 2013 to May 2018 thirty-four RSA. Mean age was 78±5,7 years, mean follow up was 18±7,2 months and the mean tuberosity healing rate was 79%. Mean ROM were: 117±24 (AAE), 18̱18 (ER) and L2 (IR). On the first analysis, healing tuberosity with cage was present on 24 (92%) patients versus 3 (37,5%) without (p<0,005). The second analysis showed a non-significant improvement on ER, IR, Constant, DASH and SSV. Complications found were three removal of prothesis after infection, one axillary nerve lesion, one ulnar paraesthesia and one humeral loosening. CONCLUSION: The use of the OMS cage allows a better consolidation of tuberosities in a significant way but no significant clinical effects was highlighted due to a small patient number in the study. LEVEL OF EVIDENCE: level III, retrospective cohort.

BACKGROUND: Although mid-shaft clavicular fractures are generally thought to be non-serious injuries that nearly always heal with non-operative treatment, recent studies found non-union rates of 3%-7% in simple fractures and 20%-33% in complex fractures. The primary objective of this study was to report the functional and anatomical outcomes after screw-plate fixation of displaced mid-shaft clavicular fractures with three or more fragments. HYPOTHESIS: Screw-plate fixation in this indication is an excellent treatment option that minimises the risk of complications. METHODS: A search of our database from 6 January 2012 to 27 December 2016 identified 410 cases of clavicular fracture, of which 250 were managed surgically, including 172 meeting our inclusion criteria and having complete data. These 172 patients were managed using a curved pelvic reconstruction plate with 3.5-mm non-locking screws positioned over the antero-superior aspect of the clavicle. All 172 patients were re-evaluated at least 1 year after surgery by an independent assessor, who determined the UCLA score. RESULTS: We studied 172 patients, 154 (89.5%) males and 18 females with a mean age of 34.5±14.5 years (range, 13-69 years). In 84.5% of cases, the fracture was a sports injury, and the most common sports were skiing (26%), cycling (21%), and mountain biking (18.5%). Of the 172 fractures, all but 1 healed, within a mean of 87 days (range, 45-120 days). After removal of the fixation material, 8 (4.5%) patients experienced a recurrent fracture, within a mean of 90 days (range, 2-210 days); 4 of these recurrent fractures were caused by high-energy traumas occurring 6 months after implant removal. The UCLA score determined at re-evaluation indicated that the outcome was excellent in 164 (95.5%), good in 5 (3%), and fair in 3 patients. CONCLUSION: Internal fixation using a curved pelvic reconstruction plate fixed with 3.5-mm screws provides excellent functional and anatomical outcomes in patients who have displaced mid-shaft clavicular fractures with three or more fragments. LEVEL OF EVIDENCE: IV, retrospective cohort study.

Since the early 1970s, total knee arthroplasties have undergone many changes in both their design and their surgical instrumentation. It soon became apparent that to improve prosthesis durability, it was essential to have instruments which allowed them to be fitted reliably and consistently. Despite increasingly sophisticated surgical techniques, preoperative objectives were only met in 75% of cases, which led to the development, in the early 1990s, in Grenoble (France), of computer-assisted orthopaedic surgery for knee prosthesis implantation. In the early 2000s, many navigation systems emerged, some including pre-operative imagery ("CT-based"), others using intra-operative imagery ("fluoroscopy-based"), and yet others with no imagery at all ("imageless"), which soon became the navigation "gold standard". They use an optoelectronic tracker, markers which are fixed solidly to the bones and instruments, and a navigation workstation (computer), with a control system (e.g. pedal). Despite numerous studies demonstrating the benefit of computer navigation in meeting preoperative objectives, such systems have not yet achieved the success they warrant, for various reasons we will be covering in this article. If the latest navigation systems prove to be as effective as the older systems, they should give this type of technology a well-deserved boost.

PURPOSE: Some recent articles have suggested that in the case of large varus deformity, it may be advantageous to leave some residual post-operative varus as a means of improving functional outcome. The objective of this study is to compare the results of total knee replacement (TKR) performed for significant varus deformity (HKA < 170°) where there is a residual post-operative varus (HKA < 180°) to the results of TKR for significant varus deformity with either neutral post-operative (HKA = 180°) or mild valgus post-operative alignment (HKA > 180°). METHODS: This series was made up of 208 knees. The mean pre-operative HKA angle was 166 ± 3° (154-169°), of which 150 were followed up for a mean 8.5 years (58 lost to follow-up). Based on post-operative radiographs, two groups were formed: group 1 (88 knees) in which post-operative alignment was 177.8 ± 1° (175-179°) and group 2 (62 knees) in which post-operative alignment was 181 ± 1° (180-184°). RESULTS: The mean international knee society (IKS) score for group 1 was 178.8 ± 22 points (113-200) and 181.7 ± 22 points (95-200) for group 2. Oxford knee score was 20.4 ± 9 points (12-45) in group 1 and 19.2 ± 9 (12-50) in group 2. The results were slightly better in group 2 (in slight valgus) but this difference was not statistically significant (p = 0.44 and 0.4). CONCLUSION: The results of knee replacement performed for severe varus deformity are not adversely affected by post-operative valgus alignment. There is in fact a trend towards superior results for neutral or valgus alignment than slight residual varus, but this difference was not statistically significant.

INTRODUCTION: The Tape Locking Screw (TLS®) technique for anterior cruciate ligament (ACL) reconstruction has the advantages of using only one hamstring tendon (semitendinosus) by preparing a short graft secured with screws and braided strips. The theoretical pitfall of this technique is that the graft length is determined arbitrarily. Thus, if the blind tunnels are not long enough, it will be impossible to tension the graft properly upon fixation. The primary objective of this study was to determine the postoperative side-to-side difference in knee laxity. We hypothesized that ACL reconstruction with the TLS(R) system would result in 3mm or less side-to-side difference in knee laxity. MATERIAL AND METHODS: This was a prospective single-center, single-surgeon study performed on patients operated between December 2014 and June 2016 who had a minimum 12 months' follow-up. The pre- and post-operative side-to-side difference in knee laxity was measured with a KT-1000 arthrometer. Secondary outcomes were the pre- and post-operative IKDC, Lysholm and Tegner functional scores. RESULTS: Sixty-one patients were included: 49 men (80%) and 12 women (20%). The average age was 31.6±13.7 years. The average follow-up was 19.3±6.3 months. The average side-to-side difference in laxity went from 6.5mm (min 3; max 12) preoperatively to -0.1mm postoperatively (min -5, max 4) (p<0.01). The average IKDC went from 39.7±12 preoperatively to 94.1±11.2 postoperatively (p<0.005), the average Lysholm score went from 41±12.9 to 95.5±9.8 (p<0.005), and the average Tegner score went from 6.3±1.5 to 4.3±1.4 (p<0.005). Patients were able to return to sports an average of 6.1 months after surgery. In terms of complications, 4.9% of patients developed a cyclops lesion and required surgical revision. DISCUSSION: This study found very good reduction in postoperative laxity after a minimum 12 months' follow-up when ACL reconstruction is performed with the TLS® technique. LEVEL OF EVIDENCE: IV, prospective cohort study.

INTRODUCTION: The coracoid block technique described by Latarjet was modified by Patte and Walch in order to increase the glenoid surface. Saragaglia further modified this technique and described a minimally invasive approach which allows faster post-operative recovery. The aim of this study was to evaluate the medium-term functional and radiological results of this technique. METHODS: This is a single surgeon cohort of 40 shoulders in 38 patients (32 men, 6 women) with an average age of 34.5 years operated on between January and December 2014. The skin incision was 3 to 6 cm long allowing the bony block to be passed under the subscapularis tendon without sectioning it and to be placed in lying position. The bone block was fixed with a 6.5 cancellous screw or a 7.0 cannulated screw. RESULTS: At an average follow-up of 48 months, there were no recurrent dislocations. The average WOSI score was 42, the average Constant score was 95 corrected to 97% and the average SSV was 97. Visual analogue scores were 0 at rest and 0.6 with activity. The bone block healed in 92.5% of cases. It was flush with the edge of the glenoid in 84% of cases, lateralised in 10% and medialised in 6% of cases. Mean internal rotation power was 12 kg in the operated shoulder compared with 9 kg in the non-operated shoulder. CONCLUSION: The treatment of recurrent anterior shoulder instability by mini invasive Latarjet gives excellent medium-term functional results. The rate of recurrent dislocation in this series was zero and internal rotation power was well preserved. This is an excellent alternative to arthroscopic procedures which are yet to demonstrate their superiority over open surgery.

PURPOSE: Cysts of the proximal tibiofibular articulation are rare and their optimal treatment remains unclear. The objective of this study was to evaluate the results and complications of the treatment of synovial ganglion cysts of the proximal tibiofibular articulation by simple excision or by excision and fusion of the proximal tibiofibular joint with a limited fibula excision. METHODS: Between January 2005 and December 2016, seven male patients with an average age of 46 years were treated for a ganglion cyst of the proximal tibiofibular articulation. Nine procedures were performed in total. Four patients underwent primary cyst excision, two underwent revision cyst excision and three underwent revision cyst excision with arthrodesis of the proximal tibiofibular joint and partial excision of the fibula (two patients underwent two procedures). RESULTS: Average follow-up was 79 months. The recurrence rate was 25% for simple cyst excision, 100% for revision cyst excision and 0% for cyst excision with arthrodesis. Average kitaoka score was 98 for simple cyst excision and 100 for cyst excision with arthrodesis (P = 0.34); resting visual analogue scores (VAS) were zero in both groups. With activity VAS was 0 for simple cyst excision and 1.6 in the arthrodesis group (P = 0.33). Two of the three arthrodesis patients went on to successful fusion. The third patient has an asymptomatic pseudarthrosis. CONCLUSION: Simple primary cyst excision has a high failure rate at 25%. Revision cyst excision without fusion failed in all cases. We therefore recommend arthrodesis with limited fibula excision.
