RESUMO
Background: There are no papers exploring the impact of COVID-19 pandemic on the injection-based practice in patients affected by different rheumatic diseases, including osteoarthritis. The aim was to investigate the impact of COVID-19 pandemic on injection-based practice trough the Italian country. Study design: A survey-based retrospective cross-sectional study. Methods: An Italian-language questionnaire was developed by a group of senior researchers and distributed by e-mail to some Rheumatology, Orthopedic and Rehabilitation Units from different geographic areas of Italy. The survey included information about the number of injections performed during COVID-19 pandemic (stratified by injected agents and injected joint), in comparison to the pre-pandemic period, and the possible reasons behind an eventual reduction. Responses were collected and descriptive analysis calculated. Results: Eleven centers of the National Health Service completed the survey. The activities of the injections services significantly decreased across the country with a percentage of reduction of 60% compared to the pre-pandemic period. A significant reduction of both intra-articular and peri-articular injections was registered. Among intra-articular. treatments, the most affected ones were the hyaluronic acid injections, when compared to corticosteroids. A significant decrease of the total amount of peri-articular injections was observed. The strict government restrictions and the fear of patients to become infected represented the most limiting factors. Conclusions: The reported decrease of the injection-based practice in our country during the COVID-19 pandemic highlights the detrimental effects of the COVID-19 pandemic on the management of chronic musculoskeletal diseases with possible negative consequences in terms of disability and quality of life.

Patient-specific instrumentation is a surgical technique that was created to improve the accuracy of implantation, surgical time and workflow in total knee arthroplasty. This study is a single-center, single-surgeon randomized clinical trial. The aim of this work was to evaluate clinical efficacy of PSI versus standard surgical instrumentation in malalignment risk and blood loss reduction. From April 2015 to September 2016, 40 patients for a total of 40 knees were included in the randomization process. Each patient underwent CT scan of the lower limb including hip, knee and ankle joint with the realization of the PSI system and the TKA with Medacta GMK Primary®. Patients were evaluated 1 month after surgery with X-ray and after 2 months with clinical examination and assessment by Knee Society Score (KSS). Blood loss was detected by adding the values calculated in the operative room and the blood loss in the vacuum systems. In the study group, mean value of KSS was 85.2 (IC 95% 81.2-88.5), mean blood loss was 657 ml (IC 95% 580.6-735.4), and mean value of femorotibial angle was 178.8° (IC 95% 178.5-179.3). In the control group, mean value of KSS was 87.2 (IC 95% 85.3-89.4), mean blood loss was 866.5 ml (IC 95% 763.3-972.5), and mean value of femorotibial angle was 178.9°(IC 95% 177.6-180.3). The Student t test detected a significant difference in blood loss between groups (p < 0.05), and no differences were found between KSS. The single-use instrumentation should improve precision, operative time, turnover time, sterilization and maintenance costs and could help to reduce infection risks. Our results confirm only the improvement on reducing blood loss. In our opinion, this technique should be used in selected patients when the surgeon could have some difficulties to perform femoral cuts on coronal plane or when patients need to have a very little blood loss due to other conditions.

Nutraceuticals are compounds that serve as nutrition with an easy accessibility and favourable safety profile. Recent studies showed their potential activity on osteoarthritis (OA) inflammation and cartilage metabolism. We investigated the effect of methylsulfonylmethane (MSM) and mobilee in human OA chondrocyte cultures exposed to interleukin (IL)-1ß. OA cartilage was obtained from femoral heads of five patients undergoing total replacement surgery. Chondrocytes were incubated with mobilee (200 and 500⯵M) and MSM (2000 and 6000⯵M) in presence of IL-1ß (10â¯ng/mL) and nuclear factor (NF)-κB inhibitor (BAY 11-7082, 1⯵M), for 24 and 48â¯h. Viability and apoptosis were performed by MMT and flow cytometry. The metalloproteinase (MMP)-1,-3,-13 and type II collagen (Col2a1) were analyzed by qRT-PCR and ELISA, and NF-κB activation by immunofluorescence. IL-1ß stimulus determined a significant regulation of survival, apoptotic ratio, as well as of gene expression and serum levels of MMP-1,-3,-13 and Col2a1 in OA chondrocytes compared to baseline. Mobilee and MSM incubation significantly reversed the effect of IL-1ß. IL-1ß significantly induced NF-κB p50 nuclear translocation, which was significantly counteracted by the pre-treatment of OA chodrocytes with the tested compounds. BAY11-7082 significantly modulated MMPs and Col2a1 expression respectively to basal state. Co-treatment of IL-1ß with mobilee, MSM and BAY11-7082 didn't cause changes of MMPs or Col2a1 beyond that caused by each single treatment. We demonstrated that MSM and mobilee have a beneficial effect on OA chondrocytes metabolism, probably due to the modulation of NF-κB pathway, providing a powerful rationale for the use of these substances in OA treatment.

PURPOSE: The injury of anterior cruciate ligament (ACL) causes joint instability and, in the absence of adequate treatment, progressive joint deterioration, meniscal lesions and development of post-traumatic osteoarthritis. METHODS: The purpose of this study was to evaluate the clinical, functional and radiographic outcomes and complications in a consecutive case series of 60 patients with minimum follow-up of 5 years who underwent an arthroscopic surgery for ACL reconstruction using LARS™ ligament. Patients with concomitant meniscal or chondral lesions in the same knee were excluded. RESULTS: The subjective evaluation of the patients involved in the study (Lysholm score, IKDC score and Tegner activity level scale) shows good/excellent results. The range of movement is optimal in most patients, and pain symptoms are considered mild. A total of 31.25% of the patients did not change their lifestyle that they had before the injury. None of the patients underwent resurgery in the same knee. In 85.4% of cases, X-ray images showed no signs of osteoarthritis after ACL reconstruction. CONCLUSIONS: Comparable with other series showed in the literature, this study assesses that the use of LARS™ in reconstruction of ACL is an excellent option for treating >40-year-old patients requesting rapid return to daily activities/sports also at the first surgery. By restoring knee stability, articular degeneration at short and medium follow-up was avoided.

PURPOSE: The aim of this study is to follow morphological imaging characteristics and osteointegration of TruFit® bone graft substitute (BGS) plugs in cases of chondral and osteochondral defects of the articular surface of the knee joint, using high-quality cartilage-sensitive 3-T magnetic resonance imaging (MRI), linked to clinical outcomes. METHODS: The MRI was used to assess osteointegration and biological evolution of the TruFit® BGS plugs in cases with minimum 5-year follow-up: The TruFit® plug was used in 46 patients for a total of 47 cases with mean age of 57.89 (range 32-80). In this study, we reviewed only the cases with minimum follow-up of 5 years: 5 patients with mean age 64.4 years (minimum 38, maximum 80). The mean follow-up was 71 months (range 63-77). Patients were evaluated clinically, with Lysholm Knee Scoring Scale and MOCART Scale. RESULTS: 3-T MRI, which is preferable to 1.5 T for the better signal-to-noise ratio, contrast and the ability to acquire morphological images at higher spatial resolution, shows a satisfactory integration of bone scaffolds in studied cases for more than 5 years and a satisfactory restoration of the articular cartilage, with the exception of a case of which we still have to consider the factors age, type of lesion and the relationship between the plugs implanted. CONCLUSION: Clinical and radiological results significantly improve in a longer follow-up time.

Allografts techniques remain the best reconstructive strategy for chronic extensor mechanism lesions after total knee arthroplasty (3) but outcomes depend strictly on the host tissue-allograft junctions healing. The purpose of this study is to evaluate if modern techniques of adding autologous bone marrow cells concentrate enriched with platelet-rich fibrin, provide better healing of the allograft. We present the case of an 86 years old patient affected by patellar tendon rupture after TKA. A whole extensor mechanism allograft was performed adding a bone marrow cells concentrate enriched with platelet-rich fibrin on the host tissue-allograft junctions. Preoperatively and at each follow-up the value of Knee Society Score and radiographic consolidation signs were recorded. Radiographic controls showed clear signs of consolidation already at 1 months follow-up and a solid fusion at 3 months. This case report describes a valid method to improve healing using a tissue-construct engineered with stem cells and growth factors.
RESUMO
Treatment of bone metastases is often palliative, aiming at pain control and stabilization or prevention of pathological fractures. However, a complete resection with healing purposes can be performed in selected cases. The aim of our work was to evaluate the survival of megaprostheses used for reconstruction after bone metastases. Between January 2001 and March 2015, we implanted 169 Megasystem-C® (Waldemar LINK® GmbH & Co. KG, Hamburg, Germany) after bone metastasis resection. Patients, 95 females and 74 males, were operated at an average age of 61 (12-87) years for proximal femoral resection in 135 (79.9%) cases, distal femur in 24 (14.2%), proximal tibia in 6 (3.6%), total femur in 3 (1.8%) and intercalary femur in 1 (0.6%). Mostly, breast cancer metastases (30.8%), kidney (17.8%) and lung (14.2%) were treated. At an average follow-up of 21 (1-150) months, we found a 99.4% overall limb salvage and a 96.1% overall survival rate at 1 year, 92.8% at 2 years, and 86.8% at 5 and 10 years. We found 9 (5.3%) mobilization cases of the proximal femoral implant, 3 needed surgical reduction; 2 (1.2%) cases of aseptic loosening of the prosthetic stem; 2 (1.2%) periprotetic infection cases, one requiring a 2-stage revision. Few literature studies have evaluated the survival of megaprosthetic implant in the treatment of bone metastases. Our data show how in this specific context the rate of complications is significantly lower than expected in general orthopedic orthopedic surgery. The use of modular prostheses is a valid reconstructive strategy after bone metastasis resection in selected patients. The rate of short-term complications is exceptionally low; further studies will have to confirm this in the longer term.
RESUMO
BACKGROUND: The tibial plateau fractures involve one of the main weight bearing joints of the human body. The goals of surgical treatment are anatomical reduction, articular surface reconstruction and high primary stability. The aim of this study was to evaluate the clinical and functional outcomes after internal plate fixation of this kind of fractures. MATERIALS AND METHODS: From January 2009 to December 2012, we treated 75 cases of tibial plateau fracture with angular stable plates. We used Rasmussen Score and the Knee Society Score for the clinical and functional evaluation. Twenty-five cases that underwent hardware removal had arthroscopic and CT evaluation of the joint. RESULTS: No complications occurred. The clinical and functional evaluation, performed by the KSS and Rasmussen Score, highlighted the high percentage of good-to-excellent results (over 90 %). In every case, the range of motion was good with flexion >90°. Arthroscopy showed the presence of chondral damage in 100 % of patients. In all the cases, we found that X-ray images seem better than the CT images. CONCLUSIONS: Angular stable plates allow to obtain a good primary stability, permitting an early joint recovery with an excellent range of motion. Avoiding to perform a knee arthrotomy at the time of fracture reduction could prove to be an advantage in terms of functional recovery. The meniscus on the injured bone should be preserved in order to maintain good function of the joint. X-ray images remain the gold standard in checking the progression of post-traumatic osteoarthritis.

BACKGROUND: Chondral or osteochondral defects have been reported in 60-67 % of patients in studies reporting knee arthroscopies. The surgical management of chondral and osteochondral defects (OCD's) of the articular surface of the knee joint remains a controversial topic. Osteochondral injuries can be treated with transfer cartilage procedure and with implantation of biodegradable scaffolds. For patients over 50 years old with largest osteochondral lesions, we prefer to use the biodegradable scaffold, like Trufit(®) plug (Smith & Nephew, Andover, MA). The purpose of this study is to evaluate the outcome of this series of surgical procedure with Trufit. METHODS: In our institute, the Trufit was used for the treatment of one or more focal osteochondral lesions of the femoral condyles positive MRI with or without concomitant ligamentous or meniscal pathology. We reviewed 30 patients with mean age of 60.57 years (range 32-79 years) with a clinical and imaging control at 6, 12, 24 and 48 months of follow-up. RESULTS: The clinical evaluation has shown the good outcome. The MRI conducted has shown the progressive partial integration of the scaffolds. CONCLUSIONS: The results obtained indicate a clear improvement of the clinical symptoms and slowing joint degeneration. The clinical and imaging results confirm that the Trufit constitutes a valid surgical alternative in case of focal osteochondral.

SUMMARY: There is still no clarity on the etiology and epidemiology of atypical femoral fractures. The purpose is to show, after a radiological review, that the incidence of atypical fractures is higher than that reported in the literature when compared to "typical" fractures that occurred in the same anatomical site. INTRODUCTION: At present, it is difficult to define the true incidence of atypical fractures associated with bisphosphonate. Our purpose is to show that the incidence of atypical fractures is higher than that reported in the literature when compared to "typical" fractures that occurred in the same anatomical site. METHODS: The authors analyzed 319 femoral fracture Rxs of patients over 60 who have had access to the PS of Clinical Orthopaedics and Traumatology II of the University of Pisa from January 2011 to February 2013. The atypical fractures have been investigated from clinical point of view, biohumoral exams, densitometry and contralateral femur X-rays, and in one case using SPECT-Tc. RESULTS: The total number of femoral fractures was 319. The medial femur fractures were 60 (46 females and 14 males), and the lateral ones were 316 (237 females and 79 males). Subtrochanteric and diaphyseal fractures were 40 (29 females and 11 males). Among these cases, two atypical fracture cases were related to female patients, one was 79 years old and the other was 77. CONCLUSIONS: The most recent literature reports that the incidence of atypical fractures is 0.6 %. However, taking into consideration only the fracture locations suitable for the identification of atypical fractures, the percentage rises to 5 %. To date, there is still no clarity on the exact etiology of fractures even if it seems to be related to a bone mineral component alteration.

Atypical femoral fractures can be subsequent to a long-term biphosphonates treatment; they have a high frequency of delayed healing. The authors describe a femoral pseudoarthrosis of an atypical fracture treated with intramedullary nailing in a female after prolonged alendronate therapy. Atypical femoral fractures can be subsequent to a long-term biphosphonates treatment even if, in the literature, there is no clarity on the exact pathogenetic mechanism. The Task Force of the American Society for Bone and Mineral Research described the major and minor features to define atypical fractures and recommends that all the five major features must be present while minor features are not necessary. Another controversial aspect regarding the atypical femoral fractures is the higher frequency of the delayed healing that can be probably related to a suppressed bone turnover caused by a prolonged period of bisphosphonates treatment. This concept could be corroborated by the Spet Tc exam. In the case of a pseudoarthrosis, there is not a standardization of the treatment. In this report, the authors describe a femoral pseudoarthrosis of an atypical fracture treated with intramedullary nailing in a female after prolonged alendronate therapy; the patient was studied with clinical, bioumoral end SPECT-Tc exam of both femurs. Many studies show the relationship between bisphosphonates and the presence of atypical fractures. These fractures should be monitored more closely due to the risk of nonunion and they require considering an initial treatment with pharmacological augmentation to reduce the complications for the patient and the health care costs.

Teriparatide is a synthetic polypeptide hormone that contains the 1-34 aminoacid fragment of the recombinant human parathyroid hormone. It has been approved for the treatment of postmenopausal women with osteoporosis who are at high risk for sustaining a fragility fracture. It has been shown that teriparatide also accelerates fracture healing by improving the biomechanical properties of the fracture callus, increasing endochondral ossification and bone remodeling in animal models. This effect has been observed in several case reports. Fracture healing disorders negatively affect the patient's quality of life and result in high healthcare costs, as a second surgery is required to stabilize the fracture and stimulate bone biology. Future biotechnologies that accelerate fracture healing may be useful tools. We present a case report of delayed union of a femoral fracture treated with teriparatide. She was diagnosed with right distal metaphyseal femoral fracture on total knee arthroplasty. She underwent surgery at our center consisting of ORIF with lateral femoral locking plate in October 2011. Radiologic controls at 5 and 7 months did not show any signs of healing. After 2 months of treatment with teriparatide, the X-ray showed the presence of bone bridges and a decreased gap between fragments and a different aspect of neoformed bone. After 3 months of treatment, healing was complete. Our case report seems to confirm the possible effect of TPTD as bone induction through a more rapid healing of fractures. The TPTD could have a potentially important role in treating some forms of nonunion and delay in consolidation. Thus, one could hypothesize the possibility of a medical treatment with TPTD both as a preventive way and also as a support to the synthesis in high risk of nonunion fractures and complexed fractures in osteoporotic bone.

BACKGROUND: In orthopedic field is growing interest in the use of stem cells: this mesenchymal multipotent line (MSCs) can lead to differentiation into osteocytes and thus the formation of bone tissue. In literature applications of this line are described in injuries of tendons and ligaments, small bony avulsions, nonunion fractures and cartilage defects. AIM: Utilize MSCs expanded in laboratory in case of atrophic pseudoarthrosis of the upper limb. MATERIALS AND METHODS: We obtain the amount of cell necessary for the implant by the collaboration with the UO Haematological Department. For the procedure we make a blood sample from the iliac crest bone marrow and a subsequent phase of selection and cultivation of mesenchymal line for 3 weeks, to get a sufficient amount of tissue to be used, which is presented at the time of surgery on a scaffold made by autologous plasma gel and CaCl(2). We reassessed our experience in 8 different types of upper limb fractures result in pseudarthrosis and delayed of consolidation: 4 women and 4 men, average 44 years old followed with a follow-up of 50.3 months. In all cases the site of non-union has been revitalized (by microfractures and drilling) and a synthesis was performed with a rigid plate. So we fill the bone gap with autologous bone and mesenchymal stem cells expanded in the laboratory. RESULTS: We have a radiographic healing in 8 cases and no adverse events were highlighted. CONCLUSIONS: Using this cells line we obtained encouraging but certainly not conclusive impressions, according to the limited number of cases and lack of adequate comparative studies. In tissue engineering are also certainly needed further investigations and developments.

We analyse this rare pseudotumour with few case reports in the orthopaedic literature. Elastofibroma dorsi is an uncommon benign soft tissue pseudotumour usually located at the lower pole of the scapula. This study is a clinical assessment of 5 patients. All the patients had their diagnosis based on clinical and MRI findings and had excision biopsy. The patients were followed for a mean period of 24 months. No patient had residual symptoms. We have only one recurrence. Surgical excision is recommended when it causes functional disability, compression symptoms, an asymmetric outline of the chest wall, or when it is more than 5 cm in diameter. Pre-operative tissue diagnosis is not necessary in most cases. Despite its rarity, the elastofibroma dorsi should always be suspected with the emergence of a swelling in the subscapularis, especially in females and in old age.

The choice of the most appropriate procedure for surgical treatment of type IV-V and VI dislocations of the acromioclavicular joint according to Rockwood's classification has always been troublesome because of complications such as residual instability of the joint, delayed arthrosis of the A-C, delayed osteolysis of the clavicle, host intolerance towards artificial ligaments and because of the need of early mobilization of the affected limb. In our study, 17 male patients, ranging in age from 21 to 79 years and affected by A-C dislocation grade IV and V, both acute and chronic, underwent surgical reconstruction of the A-C joint capsule and extra-articular ligaments with ligament augmentation and reconstruction system (LARS) artificial ligament. Following surgery, their affected limb was braced for 3 days and thereafter all patients began an early active and passive mobilization programme. Patients eventually all returned to their previous working and recreational activities. Throughout thorough clinical and radiographic evaluation and the use of both Constant score and Simple Shoulder test, the aim of our study is to prove that at mid-term follow-up, the reconstruction of the conoid and trapezoid ligaments with LARS is a valid and safe alternative to other procedures.

Distal radius fractures can be treated with different methods, depending on the type of fracture and, on our experience, according to the Fernandez algorithm. The report presents our experience treating distal radius fractures using a volar plate. We reviewed retrospectively 20 patients treated, during a period of 3 years (May 2008-May 2011) at our center, for unstable distal radius fractures using a volar plate. All patients were reviewed by thorough clinical examination and standard radiographs of the operated wrist. For the clinical evaluation, we used Mayo Wrist Score and DASH Score. At review, the injured wrist had recovered an average range of motion in flexion-extension of 120°, and the grip strength was an average of 50% compared to contralateral side. Overall, results at Mayo Wrist Score were good to excellent in 30%, satisfactory in 55%, and poor in 15%; results at DASH Score were good to excellent in 90%, satisfactory in 10% with no poor case. The majority of patients were fully satisfied with the results (65%), 20% of patients were partially satisfied, 5% were poorly satisfied, and 10% were not satisfied. At review, 4 patients reported the presence of transient paresthesia localized to the first three rays of the hand. At radiographic evaluation, the majority of patients had a radial tilt between 20 and 23, ulnar variance between 0 and 3, and dorsal tilt between 9 and 14. The treatment of unstable distal radius fractures with a volar plate provided stable internal fixation and allowed early function and was associated with a low complication rate.
