RESUMO
OBJECTIVE: Due to a growing number of lateral fragility fractures, and their high economic and social impact, we evaluated the combined drug therapy effectiveness in lateral fragility femur fractures treated by intramedullary nailing surgery comparing the clinical and radiological results of two groups of patients. PATIENTS AND METHODS: From May 2019 to March 2020, we carried out a prospective observational study comparing the results of patients with femoral lateral fractures treated by the same intramedullary nail (PFNA Synthes®) using Clodronic acid and Vitamin D (study group, 25 patients) compared to patients with the same fractures treated with Vitamin D alone (control group, 25 patients). The evaluations were based on bone biochemical markers (serum calcium level, serum phosphate level, parathyroid hormone, Vitamin D, serum C-terminal telopeptide), Visual Analogic Scale and HHS (Harris Hip Score) score, and femur densitometric views. In order to evaluate the femur neck mineral bone density (BMD), two areas have been identified on the Anterior-Posterior view: the Region of Interest (ROI)1 (under the head screw) and the ROI2 (above the femoral screw). The BMD has been calculated using femur densitometric views at T0 (1st day post-surgery) and at T1 (12 months later). RESULTS: As far as the BMD average of ROI1 is concerned, we found a significant statistical increase at T1 in the study group (0.93±0.07 gr/cm2) vs. control group (0.88±0.08 gr/cm2), p=0.04. Both biochemical and densitometric values were statistically increased in the study group from T0 to T1 (p<0.05), while control group showed an improvement in the biochemical values only. CONCLUSIONS: Thanks to a one year follow-up, we are able to demonstrate that the administration of an adequate drug therapy after surgery can lead to a better control of the bone remodeling and reabsorption process.

OBJECTIVE: Hip arthroplasty is one of the most performed surgeries in orthopedics. Rehabilitation process after surgery allows rapid recovery of joint functions in absence of pain in most patients. During COVID-19 pandemic, rehabilitation clinics have reduced the number of beds available. Thus, an increasing number of patients were forced to home rehabilitation programs. Our study aimed at determining any significant differences in clinical and functional outcomes between those patients who underwent a home rehabilitation program and those others who were granted a place in a Rehabilitation clinic during COVID-19 pandemic, at mid-term follow-up. PATIENTS AND METHODS: An observational retrospective single-center study was designed. The patients included were 63, divided into two groups: Group A (29 patients) for home rehabilitation, and Group B (34 patients) for clinic rehabilitation. Follow-up was performed at 1, 6 and 12 months after surgery. Clinical evaluation was assessed through Oxford Hip Score for hip function, Visual Analogue Scale (VAS) for pain and hip range of motion (ROM) to evaluate joint recovery. RESULTS: ROM was compared at follow-up with significant differences 12 months after surgery (107.93° group A vs. 104.7° group B; p=0.0168). Pain felt by patients according to the VAS scale showed no significant differences at follow-up (1 month 3.27 vs. 3.65 p=0.1489; 6 months 1.89 vs. 2.18 p=0.105; 12 months 0.58 vs. 0.68 p=0.6263). Regarding the Oxford Hip score, significant differences emerged at 1-month follow-up (38.75 group A vs. 37.94 group B; p=0.0498). CONCLUSIONS: At mid-term follow-up, little differences were found between patients who went through home rehabilitation and those who went to a rehabilitation clinic. Therefore, decreasing the number of beds available in rehab clinics during COVID-19 pandemic was not an obstacle for elective surgery for orthopedic surgeons.

OBJECTIVE: Muscular flaps may represent a valid treatment option for prosthetic infection after knee arthroplasty. PATIENTS AND METHODS: We present the results of 20 consecutive patients treated with the use of medial gastrocnemius flap for the management of different types of injuries or integumentary defects after total knee arthroplasty. Tissue necrosis or dehiscence occurred within 1 and 2 months after arthroplasty. The mean follow-up was 23.4 (12-60) months. Clinical outcome was evaluated according to the infection control rate and post-operative Knee Society Score (KSS). RESULTS: Prosthesis salvage and complete restoration of skin coverage were achieved in all patients. Functional assessment was performed using the KSS score. The final knee KSS score was classified as excellent (score: 80-100) in 0 patients, good (score: 70-79) in 17 patients, fair (score: 60-69) in 2 patients, and poor (score: 60) in 1 patient. Residual Extension Deficit: 0-20°; Very Satisfactory in 17 patients. 30-70° Satisfactory in 2 patients, 80-90° Unsatisfactory in 1 patient. Patients who successfully underwent flap treatment experienced a much greater increase in both components of the KSS score. CONCLUSIONS: The results highlight the effectiveness of medial gastrocnemius muscular flap for the treatment of prosthetic knee infection, in terms of function, limb salvage, cost-effectiveness and post-surgery quality of life. Further larger studies may consolidate these findings.

OBJECTIVE: The use of megaprosthetic implants could provide substantial advantages in elderly population affected by complex fractures. The aim of the study was to identify the patients suitable to megaprosthetic implants in the treatment of lower limbs fractures, as well as periprosthetic fractures. PATIENTS AND METHODS: From January 1st, 2015, to December 31st, 2021, all patients affected by femoral fractures with severe bone loss or previous surgery failure were retrospectively reviewed. ADL, IADL, SF-12 values pre- and post-operative were recorded. Hemoglobin value, NLR, PLR were recorded pre- and peri-operatively for all patients. Complications were recorded. All patients underwent a radiological follow-up. Significance was set at p ≤ 0.05. RESULTS: 23 patients were considered eligible, 10 males and 13 females; the mean age was 72.87 years old (± 12.33), while the mean BMI was 27.2 points (± 5.2). The mean follow-up was 2 years (± 1.4). The mean preoperative ADL and IADL scores were correlated with a positive independence of the patient, while the mean postoperative scores corresponded to a moderate-low independence. Also the mean Mental and Physical SF12 scores saw a decrease in values. NLR values were higher in the first group of patients with complications. CONCLUSIONS: A careful multiparametric and multidisciplinary patient selection is required to identify the suitable patient to this treatment.

OBJECTIVE: Massive bone loss is a serious problem in the elderly. Joint replacement with modular prostheses represents the most common reconstructive technique after oncological and non-oncological resections. Megaprostheses are broadly available, adaptable and versatile and allow early mobilization and rehabilitation. Although segmental endoprosthetic implants are now widely used and despite innovations, complications remain far high. Our purpose is to establish what happens to megaprostheses of a specific anatomical site in the long term in a population with oncologic and non-oncologic indications treated at a single center solely by a few skilled surgeons. MATERIALS AND METHODS: We retrospectively reviewed our institutional database. We collected 35 patients who underwent endoprosthetic reconstruction exclusively of the proximal femur for neoplastic and non-neoplastic disease between 2008 and 2021. The minimum follow-up was 12 months. Complications were collected and classified, and also adapted to the non-oncological setting. RESULTS: Taking into consideration the entire population, 94% of this survived the follow-up at 6 months, subsequently 85% at 1 year and 82% at 2 years. At follow-ups after 5 years, 79% of megaprostheses showed no mechanical failure. Analyzing prosthetic survival in the two groups, this was >50% at 24 months after surgery in both groups, with better survival for the oncological one. CONCLUSIONS: Proximal femur replacement can be a valid option in treatment of oncological and non-oncological cases. Due to the high complication rate, only selected cases should undergo this kind of surgical procedure.

OBJECTIVE: Proximal femur fractures are among the most common type of trauma in elderly patients, and Euthyroid sick syndrome has already been related to fractures and trauma. The evidence of a consistent inflammatory state occurring during hip fracture, made us consider as a potential marker also the neutrophil-to-lymphocyte ratio (NLR), which is already in use to measure the prognosis and guide the therapeutic management in various conditions. PATIENTS AND METHODS: A retrospective observational analysis on patients affected by proximal femur fractures was conducted. Patients were divided between affected and non-affected by Euthyroid Sick Syndrome (ESS). Standard follow up was conducted at 1, 3, 6 and 12 months. RESULTS: 79 patients were enrolled in this study. There were 19 males and 60 females, the mean age was 83.8 ± 6.5 y.o., and 44 patients were affected by ESS. Affected patients showed higher NLR values (10.2 ± 9.4 vs. 6.9 ± 3.9; p= 0.001) and higher decrease in fT3 values in the 1st post-operative day (1.8 ± 0.4 vs. 2.2 ± 0.3; p= 0.001), higher values of PTH (97.9 ± 46.2 vs. 70.1 ± 36.2; p=0.004) and lower levels of Vitamin D (18.8 ± 7.8 vs. 23.5 ± 12.9; p= 0.04). As regards complications, we found them in 27% of patients in group A, while only in 8% in Group B, with a statistically significant difference (p= 0.03). CONCLUSIONS: ESS and NLR are promising prognostic markers in PFF in the elderly patients. If used together, they could help in the pre- and post-operative management of the patients.

OBJECTIVE: The humerus is the second long bone most affected by pathological fractures. According to Capanna and Campanacci criteria, surgical choice is based on bone metastasis location, on the patient's status and on the residual functional capacity. Metadiaphysis is an area of conflict in the choice between megaprosthesis implant and intramedullary nail osteosynthesis. This study compares these two surgical procedures in terms of reacquired functionality and local control of metastasis. PATIENTS AND METHODS: Thirty-eight patients (17 males and 21 females; mean age: 66 years old) treated in our institution between January 2010 and December 2020 for pathological humeral metadiaphyseal fractures caused by metastasis, were included in this study. We choose the Musculoskeletal Tumor Society rating system (MSTS) and the Quick Disability of Arm-Shoulder-Hand (QuickDASH) scores for the evaluation of the upper limb function after surgery. RESULTS: Eighteen (47%) pathological fractures were treated by resection and megaprosthesis implantation, twenty (53%) were treated by medullary nail osteosynthesis. A reduction in pain and greater mechanical stability in the immediate post-operative period was found in all patients. Twenty-two patients died (58%) and sixteen survived (42%). Long-term functional recovery of patients undergoing osteosynthesis is greater than megaprothesis group. CONCLUSIONS: Both medullary nail osteosynthesis and resection and megaprosthesis implantation guarantee excellent recovery at 72 months after surgery, improvement in quality of life and pain relief. Patients treated with osteosynthesis showed a great short-term functional recovery since the joint portion of the limb is not involved, whereas patients treated with megaprosthesis showed better local oncologic control. It is therefore possible to define the type of treatment not only on the localization of the fracture (diaphysis or epiphysis) but above all on the conditions and characteristics of the patient.

OBJECTIVE: Periprosthetic femoral fractures (PFF) are a serious complication in patients who have undergone hip arthroplasty. Some authors consider revision arthroplasty as the gold standard in the surgical treatment of Vancouver type B2 and B3 PFF. Others, however, prefer treating PFF by open reduction and internal fixation (ORIF), without revising loose stems, especially in elderly patients. In the present retrospective study, we report mid/long-term results in a series of patients affected by B2 or B3 PFF surgically treated by ORIF, using a locking compression plate (LCP), thus avoiding the need of revision arthroplasty. MATERIALS AND METHODS: We reviewed 28 patients affected by B2 or B3 PFF surgically treated between 2010 and 2017 by ORIF using a LCP, after an average follow-up of 5.5 years. The average age of the patients at diagnosis was 78 years; in 17 patients, the femoral stem was uncemented while in 11, cemented. The mean interval time between hip arthroplasty and PFF was 6.7 years. Clinical results were assessed using Harris Hip Score (HHS), while radiographic results according to Beals and Tower criteria. RESULTS: At follow-up, HHS ranged from 72 to 96 points; 8 patients had an excellent result, 12 got a good result and 8 a fair result. According to Beals and Tower criteria, all the radiographic results were excellent (9 patients) or good (19 patients). The majority of our patients returned to their previous ambulatory levels. CONCLUSIONS: According to our results, in elderly patients affected by Vancouver type B2 or B3 PFF, surgical treatment by ORIF using a locking compression plate, without a stem revision, seems to be associated with satisfactory outcome.

Ceramic materials are widely used in hip prosthetic surgery. Faced with important developments in the design and characteristics of the materials, ceramic-on-ceramic (CoC) are today the bearings in Total Hip Replacement (THR) showing the minimal wear rate. Moreover, ceramic wear debris demonstrated the absence of local and systemic toxicity. This makes ceramic bearing particularly suitable for active patients, whatever their age. The results show excellent survival rates of THRs with ceramic components and excellent clinical and radiographic scores with follow-up close to 20 years. However, the excellent outcomes of THRs with ceramic bearings are depending on appropriate and correctly performed surgical technique.

Proximal femur fractures are increasing, together with the aging of world population. One of the complications worsening this condition is infection. In this study, we try to identify risk factors that can lead to infection. We identified 122 patients with femoral neck fracture. The occurrence of infectious events were recorded (respiratory, urinary, superficial wound and periprostethic infection). There were 15 infections, mostly urinary and pulmonary, and all were treated using antibiotics. No statistical differences were found between infection and control group regarding waiting time for surgery, mean time of surgery, age, kind of fracture, type of surgery. Fever onset >38° within 72 hours from surgery was statistically correlated with early infections. Future studies must be led to identify risk factors for infection and to create a strategy to prevent this possibly lethal complication.

INTRODUCTION: Incidence of hip fractures is increasing with upward estimates representing one of the most current health problems. According to some authors this condition is associated with an early mortality rate ranging between 20% and 35% and low outcomes. One of the predictive factors of poor outcome after hip fracture is anaemia. In fragile patients, hormonal changes due to fracture and surgical trauma, may occur in the hypophyseal hypothalamus axis which may lead to the Euthyroid Sick Syndrome (ESS). This pathological condition is characterized by a reduction in the concentration of triiodothyronine (T3) with normal or slightly reduced thyrotropin (TSH) values and with or without a reduction (cancellata) ââof thyroxine (T4). ESS has been associated to an increased mortality in elderly patients. MATERIALS AND METHODS: Inclusion criteria were: age > 65y, X-ray diagnosis of proximal femoral fracture classified as AO 31A or 31B requiring surgical treatment, admittance to the emergency room within 72 hours from trauma. Exclusion criteria were: any thyroid-related pathology, concomitant acute coronary syndrome, active pneumonia, concomitant neoplastic disease, assumption of medications able to affect thyroid function, refusal to undergo surgical treatment. All patients underwent routine blood testing and a complete thyroid-hormone profile dosage before surgical operation. The same blood tests performed before surgical operation were repeated on the first and third post-operative days. RESULTS: Thirtytwo patients met the inclusion criteria and were enrolled after they accepted to participate to the study. Sixteen patients presented with ESS on admission and 16 patients did not. The mean age was 82,5 yo. There was no statistically significant difference in bleeding risk factors among the two groups. In the ESS group there was a number of blood transfusions of 1.06 units higher than the control group (p=0.01). CONCLUSIONS: We have demonstrated that patients with ESS have a higher need of red blood cells transfusion compared to patients without ESS and, thus they have a higher risk to develop anemia in the peri-operative period. We believe it would be useful to diagnose ESS in fragile patients at their arrival to the emergency room and apply a peri-operative therapeutic protocol to prevent anemia.

INTRODUCTION: Distal femur fractures (DFFs) are unusual and difficult to deal, especially in elderly patients. A consensus about a gold-standard treatment has not been reached yet. Available options include both conservative and surgical management. In elderly patients a prosthetic replacement could be a valid treatment option. Literature is lacking about the use of mega-prosthesis in this type of fractures. The purpose of the present systematic review is to examine which fracture, both acute and chronic, involving distal femur should be treated by using a mega-prosthesis. MATERIALS AND METHODS: Studies were identified by searching electronic databases. All studies that enrolled people of any age affected by a DFFs treated by using a megaprosthesis were included. Primary outcomes of the present reviews were: ROM, functional assessment and complications. Two review authors independently selected eligible trials. Disagreements at any stage were resolved by consensus or a third party adjudication. Descriptive statics was used to summarize the data. RESULTS: Thirteen article were finally included in the review. One hundred-four patients were treated with knee megaprosthesis. Three categories of patients were identified: 29 patients were affected by supracondylar femur fracture; 51 patients occurred with a periprosthetic fracture; 24 patients suffered a non-union of a previous supracondylar fracture. The follow-up varied between 6 months to 58 months. All studies showed good results in terms of improving quality of life, resuming activities of daily living (ADLs), early mobilization, ROM, shorter hospital stay. Although not frequent, the only reported complications were infection and aseptic loosening. DISCUSSION: The present review showed that the use of knee megaprosthetic implants could represent a valid treatment option aiming to reduce patients' immobilitazion and hospital stay. Good clinical outcomes with low rate of complications were reported by all included studies. Literature is lacking about long-term outcomes and complications. Moreover studies comparing knee prostheses and other types of surgical treatment (intramedullary nails, plate fixation system) are needed. CONCLUSIONS: Megaprosthesis represent a viable treatment option in patients affected by DFFs (either acute, periprostethic or non-union) because they allow immediate weight-bearing, shorter hospital stay, a fast recovery of knee function and ADLs.

The specific traumatic mechanism that leads to the formation of the butterfly fragment is debated in literature. The aim of the present study is to analyze the biomechanics of fractures with a "butterfly" fragment, using a software that simulates the movement of the lines of force (and related iso-displacement points) that occur on the bone, when traumatic forces are applied on it. We have shown that the formation of the butterfly fragment derives from the application of three forces (compression, torsion and bending) with the bending force that acts by increasing the curvature of the long bone.

With the advent of the molecularly targeted therapies, identifying molecular therapeutic targets and molecolar marker is increasingly important, especially in neoplastic diseases. Several studies show VEGF is involved in neo-angiogenesis in many solid cancers, as breast, lung, renal, gastric carcinomas, through promoting endothelial cell growth and migration. Conversely the relationship between VEFG and tumours of the musculoskeletal system is yet unclear, in particular the role of VEGF has not yet been completely understood in these tumours. Chondrosarcoma, Ewing's Sarcoma and Osteosarcoma are the tumours of the musculoskeletal system in which the activity of VEGF has been closely studied. The present study aims to give an overview focused on the relationship between VEGF and these three cancers.

Periprosthetic knee infection (PKI) remains one of the most challenging complications after total knee replacement, especially if caused by multidrug-resistant (MDR) or extensively drug-resistant (XDR) organisms. Multiple treatment options are available, such as long-term antibiotic suppression, surgical debridement with retention of the prosthesis, definitive resection arthroplasty, arthrodesis, one-stage or two-stage revision procedures, amputation. We present a rare case of a PKI caused by a XDR Klebsiella pneumoniae in a young patient who underwent a prosthetic reconstruction due to an osteosarcoma of the tibia. In this patient, the PKI has been treated using intravenous administration of Amikacin and an Amikacin-impregnated PMMA custom-made spacer. To our knowledge, only two cases that successfully used hand-mixed antibiotic-loaded spacer based on antibiotic sensitivity for the treatment of PKI caused by MDR and XDR microorganisms have been reported in the literature.

OBJECTIVE: Open fractures are insidious and life-threatening injuries. They frequently involve the leg. Our aim is to evaluate the efficacy of primary intramedullary nailing as a definitive treatment of open tibial fractures, compared to other fixation tools in terms of deep infections, healing fracture time and bony repair. PATIENTS AND METHODS: We reviewed the available literature concerning treatment and management of open tibial fractures. RESULTS: Primary intramedullary nailing is similar to delayed intramedullary nailing after external fixation in terms of union, malunion and nonunion rate. Furthermore, primary intramedullary nailing is superior compared to all other fixation tools, in terms of development of deep infections, provided that a good debridement of soft tissue, lavage of the fracture site and adequate antibiotic prophylaxis should be performed before nailing. CONCLUSIONS: Primary intramedullary nailing should be considered for the definitive treatment of open tibial fractures, providing many advantages in terms of rehabilitation, time of hospitalization and costs.

OBJECTIVE: Wide diaphyseal bone defects, above all those infected, encounter into Masquelet technique a suitable treatment. The two-step procedure allows the surgeon to eliminate the infected tissues and then to promote new bone formation. We analyzed the literature about the use of the induced membrane technique in osteomyelitis and the innovations recently suggested. MATERIALS AND METHODS: We reviewed some of the most common web databases using the key-words: Masquelet technique, induced membrane, and osteomyelitis. 66 studies were analyzed. RESULTS: Comparing the Masquelet technique to other surgical procedures it shows better functional results in large bone defects due to infection. The induced membrane is like a biological chamber that protects the autograft and induces new bone formation promoting growth factors secretion. Different authors tried to improve one or more steps of the surgical procedure. Some studies focused on polymethyl methacrylate role and the possibility to use different materials instead of cement to induce the membrane. Others analyzed the autograft harvesting and placing techniques trying to reduce the amount of bone essential to fill the gap, like the RIA technique. Moreover, bone substitutes have been used, as beta-tricalcium phosphate, that showed an osteoconductive ability. CONCLUSIONS: The survey is not a systematic review. Nevertheless, new concepts are introduced and analyzed identifying 6 areas of interest and induced membrane technique development.

OBJECTIVE: We tested and quantified the in vitro effect of silver coating on preventing development of fungal biofilm over titanium, as found in some megaprosthesis used for musculoskeletal oncological reconstruction, to evaluate the antiseptic effect of this additional feature on this class of pathogens. MATERIALS AND METHODS: Different strains and species of Candida (C. albicans, C. tropicalis, C. parapsilosis) were cultured over 6 silver-coated and 6 non silver-coated titanium (Ti-6Al-4V) samples following a standardized procedure. Then spectrophotometrical analysis and viability assay were conducted after 5 days of incubation to quantify the different extension of biofilm produced by pathogens RESULTS: Significant differences between groups (p<0.05) were found in terms of biofilm extension and pathogens viability over the different materials for any single experiment reported, with silver-coating group showing substantially lower values in terms of fungal development in all conducted assays. CONCLUSIONS: The results suggest that silver coating is a reliable and effective implementation for antifungal purpose, in addition to its widely known and demonstrated antibacterial potential. Therefore, the use of silver-coated implants may be an even wiser choice in an oncological surgical procedure where patients are particularly at risk for this infective complication due to immunosuppression caused by pharmacological treatments, although the relevant antifungal potential here shown needs to be confirmed in vivo.

Bilateral fracture-dislocation of the talus is a rare occurrence. It represents 0.06% of the dislocations and 2% of the traumas of the talus. We report the case of a 29-year-old patient with an exposed bilateral fracture of the talus following a plane accident. On the right ankle, the patient had a fracture-dislocation Hawkin 3 Gustilo II, on the left ankle presented a Hawkin 4 Gustilo IIIB. The patient was treated within six hours from the trauma. We reduced the dislocation and performed an osteotomy of the tibial malleolus and osteosynthesis of the fracture with screws. The definitive stabilisation has been achieved in both limbs with an external fixator. We evaluated the patient at 1, 3, 6, 8, 12 and 18 months from treatment, with a radiograph and with SF-36 and Foot and Ankle Disability Index questionnaires. No infection was reported, radiographs showed a successful consolidation of the fracture in both limbs. At the one year follow-up, the patient was able to walk without aids and there were no signs of osteonecrosis on the MRI. The treatment of these lesions requires timely treatment, an anatomical reduction of the fracture and patient's collaboration. The use of external fixator with internal osteosynthesis represents a good therapeutic option in Hawkins 3 and 4 type fractures.
