RESUMEN
PURPOSES: Management of distal tibia fractures in the elderly is complex. The results of conservative treatments may be disappointing and primary ankle arthrodesis is now regularly offered as an alternative. In this study, we aimed to review the outcomes of primary ankle arthrodesis for distal tibia fracture in the elderly. METHODS: We conducted a systematic review of the literature, from the Cochrane, MEDLINE, and Embase databases, on studies published in English and in French between 1950 and 2020. Only studies reporting the clinical results, the function, or the complications of primary ankle arthrodesis after ankle fracture in the elderly were included. RESULTS: We included nine studies. The total number of patients was 229: 21% of them (50/229) sustained open fractures and 41% (95/229) had three or more comorbidities. All the patients underwent a tibio-talo-calcaneal arthrodesis with a retrograde transplantar intramedullary nailing (TIMN): short nail in 52% (151/229) and long nail in 48% (78/229) of the cases. At a mean follow-up comprised between six and 21 months, 94.5% of patients (190/201) achieved bone union, 87% (123/140) recovered an ankle range of motion close to their pre-operative status, 19% (40/211) had a complication, and 11.3% (24/211) required a revision. The use of a short nail resulted in a higher rate of peri-implant complication (2%) as well as a higher rate of revision (12.4%). CONCLUSION: Primary ankle arthrodesis in recent fractures of the distal end of the tibia in the elderly frequently results in satisfactory results. The use of a long nail may be associated with a lower rate of implant specific complications.

PURPOSE: Core decompression (CD) may be effective when performed during the early stages of osteonecrosis of the femoral head (ONFH). Tantalum may be added as a rod that would allow putting some mechanical constraints on the femoral head. We aimed to estimate the rate of total hip arthroplasty after CD and insertion of a tantalum rod during early stages of OFNH. METHODS: We searched systematically Medline via PubMed and the Cochrane Library. Our primary endpoint was the rate of patients undergoing a total hip arthroplasty after CD and insertion of a tantalum rod. Secondary endpoints were the delay between the initial surgery and the arthroplasty, the functional improvement, and the rate of complications. RESULTS: We included seven studies reporting the results of 232 patients (297 hips) that were operated on by CD and insertion of a tantalum rod. At a mean follow-up of 26.97 months, 24.63% of the included hips underwent a hip arthroplasty (6-56%, SD = 17.34%). The mean delay between the initial surgery and the arthroplasty was 14.94 months (10.20-22.90; SD = 5.25), the mean improvement of Harris Hip Score was 27.66 (20.20-36.90; SD = 6.48), and the mean rate of femoral fracture was 2.43% (0-13%, SD = 4.89%). CONCLUSION: CD and insertion of a tantalum rod may represent a solution in order to improve the mechanical support and to give a rate of conversion in arthroplasty that is acceptable.

PURPOSES: Osteonecrosis of the femoral head (ONFH) is a dramatic condition resulting in joint destruction in the late stages. Total hip arthroplasty allows function recovery with satisfactory implant survival. Recently, the use of uncemented short stems has been suggested to improve the conservation of bone stock. METHODS: We performed a retrospective study on 16 hip arthroplasties-11 patients-implanted for ONFH between 2008 and 2017. We aimed to compare the outcomes of the two types of arthroplasty-"uncemented short" vs "cemented conventional" femoral stem-in terms of pain (visual analogue scale), function (Harris Hip Score), and survival (radiography). RESULTS: We included six "uncemented short" and ten "cemented conventional" femoral stems. Mean pre-operative EVA was 7.5 and the mean HHS was 40.3. At last follow-up of seven years, mean VAS was 1.2 (SD ± 0.83) in the "uncemented short" group and 1.6 (SD ± 0.97) in the "cemented conventional" group. Mean HHS was 94 (SD ± 0.81) in the "uncemented short" group and 92.6 (SD ± 2.69) in the "cemented conventional" group. However, radiographic analysis revealed a lower stress shielding in the "uncemented short" stem group. One complication occurred (hip dislocation in the "cemented conventional" stem group). CONCLUSION: Uncemented short stems total hip arthroplasties may be an interesting alternative to more conventional implants with similar functional results but less stress shielding and a bone stock economy in this young population of patients.

BACKGROUND AND HYPOTHESIS: The Latarjet procedure has been shown to be a reliable method to prevent recurrent anterior shoulder instability. Coracoid bone graft osteolysis is a potential catastrophic complication and can lead to recurrent instability. The purpose of our study is to present a novel quantitative method to measure the amount of coracoid bone osteolysis using 3-dimensional (3D) computed tomography (CT) scan imaging. MATERIALS AND METHODS: This is a prospective study with 15 patients (16 shoulders) who underwent an arthroscopic Latarjet procedure. Three-dimensional CT scans were obtained at 6 weeks and 6 months. Using volumetric analysis, we quantified the amount of bone loss using our described method. Interobserver reliability and intraobserver reliability were calculated. RESULTS: On the basis of our new volumetric analysis of the arthroscopic Latarjet procedure using 3D CT scans, we found that the superior half of the coracoid bone graft undergoes a significant amount of osteolysis at 6 months postoperatively. The interobserver reliability and intraobserver reliability were excellent. DISCUSSION: This study presents a reproducible method to quantify and compare coracoid bone graft osteolysis after an arthroscopic Latarjet procedure. We also developed a description system that may be used for comparison studies. To our knowledge, this is the first method that quantifies the amount of coracoid bone graft osteolysis using more accurate 3D CT scanning. CONCLUSION: The 3D analysis we propose is a valid method to measure the amount of coracoid bone graft osteolysis after an arthroscopic Latarjet procedure. Our description system may guide the surgeon regarding possible revision surgery when faced with significant osteolysis of the coracoid bone graft.

BACKGROUND: The number of individual patient data meta-analyses published is very low especially in surgical domains. Our aim was to assess the feasibility of individual patient data (IPD) meta-analyses in orthopaedic surgery by determining whether trialists agree to send IPD for eligible trials. METHODS: We performed a literature search to identify relevant research questions in orthopaedic surgery. For each question, we developed a protocol synopsis for an IPD meta-analysis and identified all related randomized controlled trials (RCTs) with results published since 2000. Corresponding authors of these RCTs were sent personalized emails that presented a project for an IPD meta-analysis corresponding to one of the research questions, with a link to the protocol synopsis, and asking for IPD from their RCT. We guaranteed patient confidentiality and secure data storage, and offered co-authorship and coverage of costs related to extraction. RESULTS: We identified 38 research questions and 273 RCTs related to these questions. We could contact 217 of the 273 corresponding authors (79 %; 56 had unavailable or non-functional email addresses) and received 68/273 responses (25 %): 21 authors refused to share IPD, 10 stated that our request was under consideration and 37 agreed to send IPD. Four corresponding authors required authorship and three others asked for financial support to send the IPD. Overall, we could obtain IPD for 5,110 of 33,602 eligible patients (15 %). Among the 38 research questions, only one IPD meta-analysis could be potentially initiated because we could receive IPD for more than 50 % of participants. CONCLUSION: The present study illustrates the difficulties in initiating IPD meta-analyses in orthopaedic surgery. Significant efforts must be made to improve data sharing.

OBJECTIVE: Extra-articular open fractures of the leg often result from high energy trauma. After healing, a painful ankle impingement may occur. In the event of anterior and posterior impingements, arthroscopic treatment may require two surgical positions. We propose an operative strategy to treat anterior and posterior ankle impingement after extra-articular open fracture of the leg. Our hypothesis is that this strategy is simple, effective and with a low risk of complication. MATERIAL AND METHOD: Anterior ankle impingements were treated by anterior arthroscopy in supine position; anterior and posterior impingements were treated by anterior and posterior arthroscopy in supine position; anterior and posterior impingements associated with retraction of gastrocnemius muscles were treated with anterior arthroscopy in supine position followed by posterior arthroscopy in prone position, and an open tendon lengthening of the calcaneal tendon in the same position. The anterior and posterior arthroscopic release was tested in the cadaver laboratory. Then, the surgical strategy was applied to our patients in our clinical practice. After, we analysed retrospectively the results of the strategy in the first patients treated for a painful ankle impingement after extra-articular open fracture of the leg. The data retrieved were the importance of pain (VAS), the presence of clinical instability, ankle mobility, gastrocnemius retraction and the AOFAS functional score and the post-operative complications. Then, these data were compared before the surgery and at last follow-up. RESULTS: From the cadaver laboratory, anterior and posterior arthroscopic release was possible in all cases without changing position. From our clinical practice, we included 5 patients (3 women and 2 men, mean age 43 years) suffering from an ankle impingement after extra-articular open fracture of the leg (2 patients with isolated anterior impingement, 1 patient with anterior and posterior impingement, and 2 patients with anterior and posterior impingement plus a gastrocnemius retraction). All post-operative parameters (pain, range of motion and AOFAS score) at mean follow-up of 53 months were improved. No post-operative complication was reported. CONCLUSION: We propose a surgical strategy adapted to the different clinical presentations of ankle impingement after extra-articular open fracture of the leg.

OBJECTIVE: The main objective of this study was the development of a non-invasive mathematical marker of the skin surface, the characteristic length, to predict the microstructure of the dermis. This marker, at the individual level, is intended to provide the biological age of the patient in the context of personalised medicine for the elderly. STUDY DESIGN: To validate this hypothesis, a clinical study was conducted on 22 women over 60 years old from a population of osteoporotic subjects who sustained a femoral neck fracture: a morphological analysis of the skin surface was performed on the patient's forearm and quantitatively compared with microarchitectural parameters of the dermis. MAJOR RESULTS: The Elastin-to-Collagen ratio measured on dermis samples ranged between 0.007 and 0.084, with a mean of 0.035 ± 0.02. The surface characteristic length ranged between 0.90 and 2.621, with a mean of 0.64 ± 0.51. A very strong correlation was found between this characteristic length and the Elastin-to-Collagen ratio (r = 0.92). CONCLUSIONS: This study proposes an original diagnostic tool based on morphometric indices of the skin surface and shows a direct quantitative relationship with the dermis microarchitecture and its collagen and elastin content. The proposed method allows reliable and easy access to the intrinsic ageing of the dermis, which would be a strong biomarker in a personalised collagen treatment approach.
RESUMEN
BACKGROUND: The induced membrane technique has been developed to address bone defect of critical size from various origins. Despite its exceptional efficacy, several cases underwent a failure, which is regularly associated with a septic problem. The best way to conduct in this situation remains debated. PURPOSE: To estimate use of bioactive glass S53P4 (BAG-53P4) in induced membrane technique failures or with an anticipated high risk of failure. MATERIAL AND METHOD: We conducted a retrospective analysis of patients from several medical centers in Europe where BAG-S53P4 has been used inside an induced membrane. The etiology of the defect, the bone fixation used, the delay the bioactive glass was placed, the reason why the bioactive glass was used and the results were reported. RESULTS: Eight cases were included (3 women and 5 men). Mean age was 43 years (16-82; Standard deviation 23). Mean height was 171 cm (162-184; SD 7), mean weight was 69 kg (60-85; SD 8) and Body Mass Index was 23,39 M/Kg2 (21,9-25,1; SD 1,22). Mean length of defect was 68 mm (40-100mm, SD 23). All patients received BAG-S53P4 granules (BonAlive Biomaterials Ltd, Turku, Finland) to fill the resultant cavity (3 as a stand-alone in the induced membrane and 5 mixed with autograft). Three patients were implanted with BAG-S53P4 during the second stage of a first induced membrane technique because of a high risk of infection (three open fractures); two patients were implanted with BAG-S53P4 during the second stage of a first induced membrane technique because of the great size of the defect (two infectious non-union); two patients were implanted with BAG-S53P4 as a third stage of induced membrane technique, i.e. inside a previously grafted membrane, because of a recurrence of the infection; and one patient was implanted with BAG-S53P4 during the second stage of a second induced membrane technique to avoid a new failure. At a follow-up of 16 months, all healed without any recurrence of the infection. DISCUSSION: Critical size bone defects caused by an open fracture or an active infection can usually be addressed by the induced membrane technique. However, some cases are at high risk of failure because of the occurrence or recurrence of an infection. In these cases, bioactive glass may help the surgeon to improve the rate of bone union. CONCLUSION: BAG-S53P4 may be considered as bone graft in an induced membrane technique, especially when there is a high probability of occurrence or recurrence of a bone infection.

HYPOTHESIS: The purpose was to evaluate long-term clinical outcomes and tendon structural integrity after repair of isolated subscapularis (SSC) tendon tears. METHODS: Sixty-one patients who underwent repair of isolated SSC tears were evaluated. The mean interval from symptom onset to surgery was 5.3 months. Shoulder function was investigated using the Constant score and Subjective Shoulder Value (SSV). Structural integrity of the repair and quality of the repaired tendon were assessed using magnetic resonance imaging. Independent preoperative factors affecting clinical outcomes, including patient sex, age, smoking habits, injections, dominant shoulder, profession, and tear onset (chronic vs. traumatic), were evaluated. RESULTS: A total of 35 patients (9 women and 26 men; mean age, 54 years) were included at the final 10-year follow-up because 21 patients were lost to follow-up and 5 underwent reoperations. The mean Constant score improved from 55.1 points preoperatively to 75.4 points postoperatively (P = .001). The postoperative SSV was 80.9, and the retear rate was 12.9%. Postoperative fatty infiltration increased in 26% of the patients with grades 3-4, but it was not related to lower clinical outcomes. Multivariable regression analysis revealed no correlation among the preoperative factors, including sex, age, smoking habits, injections, dominant shoulder, profession, and tear onset, and the postoperative Constant score, SSV, and tendon healing. CONCLUSION: At a mean of 10 years after repair of isolated SSC tears, clinical results were satisfactory and functional improvement was maintained in the long term. Severe fatty infiltration increased with time, but it was not related to clinical outcomes and the retear rate.
RESUMEN
BACKGROUND: Mid-shaft clavicle fractures are common and may require surgery. The objective of this study in adults with high-risk mid-shaft clavicle fractures was to evaluate the clinical and radiological outcomes of a minimally invasive surgical technique involving a minimally invasive approach, fracture reduction, temporary intra-operative external fixation, and locking plate internal fixation. HYPOTHESIS: This minimally invasive surgical technique for mid-shaft clavicle fractures ensures satisfactory radiographic fracture healing and medium-term functional outcomes, with a short immobilisation, rapid return to sports, and low complication rate. MATERIAL AND METHOD: A retrospective review was performed of patients managed using our minimally invasive surgical technique between 1 January 2012 and 31 December 2016. The primary outcome measure was the 3-month radiographic healing rate. The secondary outcome measures were duration of post-operative immobilisation, 3- and 6-month QuickDASH scores, and post-operative complications. RESULT: A total of 19 patients were included, 18 males and 1 female with a mean age of 37 years. Radiographic healing was consistently achieved within 3 months. Immobilisation duration was 3 weeks. The mean QuickDASH score was 23.75 after 3 months and 7.5 after 6 months. Return to sports occurred after 3 months. The only complication was transient paraesthesia in the distribution of the C8 nerve root in 1 patient. DISCUSSION: The management of mid-shaft clavicle fractures remains controversial. The high complication rates associated with conventional surgical techniques make treatment decisions difficult. A surgical technique characterised by temporary intra-operative external fixation to facilitate minimally invasive internal fixation may have a lower complication rate and shorter immobilisation requirements compared to conventional surgery. LEVEL OF EVIDENCE: IV, retrospective observational study.

OBJECTIVE: Prosthetic joint infection (PJI) is a serious complication of joint replacement surgery. The major pharmacological and surgical treatments required by PJI increase the risk of peri-operative complications in elderly patients. The increase in life expectancy combined with procedural advances make these treatments possible even in the oldest patients. Here, our objective was to compare the characteristics and outcomes of curative PJI treatment in patients < 80 years vs. ≥ 80 years. METHODS: A prospective single-center design was used to compare the characteristics and outcomes of curative treatment for hip or knee PJI in patients < 80 years and ≥ 80 years admitted in 2004-2014. RESULTS: Of 765 patients admitted for PJI, 590 were < 80 years and 124 were ≥ 80 years. Medical history and comorbidities were similar in the two groups. The older group had a significantly higher proportion of patients with American Society of Anesthesiologists Scores ≥ 3 and with streptococcal infection (20% vs. 13%, P < 0.05). After complete surgical excision and prolonged antibiotic therapy, the only event whose frequency differed significantly between the two groups was PJI-related death, which was more common in the older patients (6.5% vs. 0.8%, P < 0.05). The 2-year survival rate after one-stage exchange arthroplasty was > 90% in the ≥80 year group. CONCLUSION: Patients aged 80 years or older are eligible for the same curative pharmacological and surgical PJI treatments used in their younger counterparts. Before surgery, the risk/benefit ratio of the major surgical procedure required to treat PJI must be assessed on a case-by-case basis.
