Fibular fractures are the third most common stress fractures in children and adolescents. Proximal fibular location is a very rare finding, with few reports in the literature and, frequently, careful investigations before a definitive diagnosis could be necessary. The authors report a case of an adolescent 13 years old soccer player with a proximal fibular fracture that was initially underestimated and misdiagnosed and ultimately confirmed as a stress lesion by MRI.

Introduction: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty. In early infection, within four to twelve weeks from surgery, debridement, antibiotics and implant retention (DAIR) can be the initial treatment. The aim of this study is to report our case series and review current concepts reported in the literature about this topic., Materials and Methods: This was an observational cohort study that included 7 patients managed with DAIR for PJI following primary total hip replacement (THR) between 2014 and 2020. Inclusion criteria were a primary THR, direct anterior or lateral approach, DAIR procedure, and PJI. Exclusion criteria were a PJI following a revision total hip replacement or hemiarthroplasty, posterolateral approach, 1-stage revision, 2-stage revision, and Girdlestone procedure without prior DAIR. For each patient demographic characteristics, laboratory values, microorganisms involved, antibiotic therapy and outcome at one-year follow-up were registered., Results: The mean duration between THR and DAIR was 19 days. In all cases only one DAIR procedure was performed. Most infections were caused by Staphylococcus aureus (4 cases) [one methicillin resistant (MRSA)]. The other infections were caused by Streptococcus agalactiae, Staphylococcus coagulase negative and Escherichia coli. At the final follow-up, the procedure was considered as successful in 6 out of 7 patients (85%). The one with unsuccessful outcome underwent to a two-stage revision., Discussion: Our results were comparable with those of a recent systematic review of the literature. Factors that have been postulated to influence the outcome of DAIR in the management of PJIs include the timing and numbers of debridement, the exchange of components, the responsible microorganism and the duration of antibiotic treatment. In conclusion, the outcomes following DAIR are better as the indications are refined and risk factors identified. PJI prevention remains the key but the current literature still lacks well documented and effective PJI prevention protocols. (www.actabiomedica.it).

Background and Aim: Rhizarthrosis represents 10% of all arthritic manifestations and its prevalence increases with age and in women. The hyperextension of the metacarpophalangeal joint (MCPj) is consequent to a progressive dorsoradial subluxation of the trapeziometacarpal joint (TMj) in advanced osteoarthritis. The aim of this retrospective study is to evaluate the clinical and functional results of 32 patients affected by advanced rhizarthrosis who underwent to modified Burton-Pellegrini's trapeziectomy in absence of surgical correction of MCPj hyperextension in order to understand when this last step is really necessary., Methods: Patients were assessed trough DASH and PRWHE questionnaires; the functionality of the hand was assessed by carrying out specific test (grip strength, key-pinch, kapandji test, reduction of wrist flexion strength) and the degree of MCP joint hyperextension was recorded., Results: Clinical evaluation and individual satisfactory were positive in most cases (mean DASH 19 and mean PRWHE 21.8, with a reduction of 77% of VAS pain score). Kapandji test was excellent in 26 patients and grip strength and key pinch were stackable in operated and non-operated hands. Twenty-five out 32 patients presented a MCP joint hyperextension between 0° and 5°, 5 of 10° and other 2 of 15°., Conclusion: Modified Burton-Pellegrini's trapeziectomy is a valid option to treat patient with TMj osteoarthritis. The absence of surgical correction of the MCPj does not affect clinical and functional results in deformities <15°.

Background and Aim of the Work: The incidence of pelvic and acetabular fractures is increasing during the years, counting 37 pelvic fractures per 100000 people annually. No weight bearing or toe touch weight bearing are usually chosen in the initial management to allow fracture and ligamentous healing and avoid fracture displacement and fixation failure. On the other hand, early weight bearing may stimulate fracture healing and allow prompt functional recovery, faster return to work and recreational activities and reduce complications linked to late rehabilitation.  Aim of the study is to review the literature about weight bearing indications for pelvic and acetabular fractures to highlight clinical and biomechanical evidence supporting early weight bearing., Methods: Two independent reviewers independently extracted studies on early weight bearing of pelvic and acetabular fractures. All selected studies were screened independently based on title and abstract. Then the full text of any article that either judged potentially eligible was acquired and reviewed again. Any disagreement was resolved by discussing the full text manuscripts., Results: 44 studies including reviews, meta-analysis, clinical and biomechanical studies were selected., Conclusions: Despite biomechanical data, few clinical evidences can be found to support early weight bearing in pelvic and especially acetabular fractures treatment. The promising results of some clinical experiences, however, should direct further studies to clearly define the indications and limits of early weight bearing in these injuries. Recognizing intrinsic lesion stability and bone and fixation technique quality, together with patient age and compliance, should be the mainstay for post-operative management choice.

Background and Aim: Rhizarthrosis common in elderly and represents 10% of all artrhitic manifestations. Trapeziectomy with ligament reconstruction and tendon interposition remains the gold standard for stages II to IV according to Eaton and Littler. This retrospective study aimed to evaluate the results of 24 patients affected by advanced rhizarthrosis who underwent to modified Burton-Pellegrini's trapeziectomy with ligamentoplasty using the entire flexor carpi radialis tendon., Methods: Patients were assessed through DASH and PRWHE questionnaires; the examination focused also on pain symptoms (VAS score) and the results obtained in carrying out specific tests to evaluate the trapezius-metacarpal functionality (key-pinch, grip strength, Kapandji test, reduction of wrist flexion). Furthermore, postoperative complications were evaluated., Results: Clinical evaluation and individual satisfaction were positive in most cases (mean DASH 18,8 and mean PRWHE 21,7). VAS pain score reduced of 76.7%, grip strength and key pinch were similar to those of the non-operated hand and Kapandji test was excellent in 20 patients.  One superficial wound infection was encountered which resolved by specific antibiotic therapy., Conclusions: The choice of the most appropriate treatment depends on clinical conditions and socio-occupational factors of the patient (age, sex and functional needs), the degree of osteoarthritis and the presence of deformaties of the first metacarpophalangeal joint. Surgery aims to relief pain and to improve joint function and strength. According to the results observed this surgical technique has to be considered a valid option for the treatment of advanced rhizarthrosis as it provides pain relief, stability and mobility of the thumb.

Background and Aim of the Work: Osteoarthritis is the most common cause of disability in elderly. Hip osteoarthritis is the second most frequent form affecting a large joint and the social and economic impact on society of its related disability is expected to increase. The purpose of this study was to verify the efficacy and safety of ultrasound-guided viscosupplementation with high weight hyaluronic acid in hip osteoarthritis., Methods: 183 patients with painful hip OA (Kellgren-Lawrence 1-2-3) were treated from January 2014 to December 2016 with viscosupplementation. Patients were evaluated before injection (T0) and after 1,2,3,4 years through the VAS scale and Harris Hip Score (HHS). Patients who underwent to subsequent injections were followed and assessed. Subjects who underwent prosthesis were analyzed for a minimum of 6 months in order to detect any early postoperative complication., Results: The mean improvement of HHS and VAS between T0 and T1 was statistically significant. Patients who underwent subsequent injections showed a higher improvement even if statistical significance was not observed. Results showed that patients with grade 2 of osteoarthritis had the higher change in the scores. No adverse effects were registered. No early complications were reported in those patients who needed prosthesis., Discussion and Conclusions: Results observed confirm that ultrasound-guided viscosupplementation with high weight hyaluronic acid could be a possibility in the treatment of hip osteoarthritis, especially in patients with Kellgren-Lawrence grade 2 of disease. Subsequent injections are not characterized by similar positive effects. Outcomes of prosthetic surgery are not influenced by viscosupplementation.

Background and Aim of the Work: Adverse reaction to metal debris is the major cause of the high revision rates of metal on metal hip implants with femoral head size ≥ 36mm. Health authorities recommend regular surveillance even for asymptomatic individuals. The main investigations used are Co+ and Cr+ serum levels, x-rays and, eventually, ultrasound and MARS-MRI. Clinic is also assessed. The aim of this study is to identify if there is a relation between  ion levels and the clinical scores  in order to evaluate the outcome and  plan the correct management after this type of implant., Methods: 383 subjects were included and divided in 3 groups (serum ion levels >, <  and >60 µg/L). Co+, Cr+, HHS and OHS results of 1 2017 were analysed in order to show a correlation between ion levels and clinical scores ., Results: Clinical scores were similar in group 1 and 2. Differences were observed comparing the group 1 and 2 with group 3 for both variables., Discussion and Conclusions: Surveillance algorithms have been introduced by health  authorities. Nevertheless, the indication to revision surgery is not simple especially in those cases in which a discrepancy between clinic and investigations is present. In this study clinical scores seem to be less important than ion levels in the evaluation of outcomes and in order to plan the correct management in the majority of cases. Larger studies are needed to highlight the real importance of clinical scores in the decision making after these type of implants.

Background and aim of the work Monteggia-like lesions are complex and rare elbow injuries. A detailed classification and a proper surgical treatment can provide quite good functional and radiological outcomes. The aim of this retrospective study was to evaluate the mid-term results of Monteggia-like lesions surgical treatment. The other purpose was to investigate whether the complexity of ulna and radius fractures could be prognostic factors of insufficient functional results. Methods Seven women and five men, with a mean age of 59,25 years who had sustained a Monteggia-like lesion were followed up clinically and radiologically after surgical treatment. The Mayo Elbow Performance Score (MEPS) and the Quick Disabilities of the Arm, Shoulder and Hand (QUICK-DASH) score were used for evaluation at a mean of 17,5 months postoperatively (12-26). The range of movement (ROM), patients' satisfaction and neurological symptoms were also investigated. Osteolysis, implant loosening and heterotopic ossification were graded. Pearson's test was used to correlate the different classification systems used (AO/OTA, Bado and Jupiter, PURCCS, Mason) with MEPS and QUICK-DASH score. Results The mean MEPS was 84,92 (65 to 100). The mean QUICK-DASH score was 18,75 (0 to 34,1). The mean active pronation and supination was 72,5° and 59,17°, respectively. The mean active ROM of the elbow was 101,43°. Heterotopic ossifications were absent in six cases but were found in six. No statistically significant correlation was found between the analyzed variables. Conclusions Quite good functional results can be obtained in Monteggia-like lesions if injury pattern is recognized and each component of the injury is addressed. Further studies are needed to determine any prognostic factors.

Dear Members, we are going through a difficult period in every aspect, which has seen us to react to the epidemic aggression and then to reconstruct what has been damaged or destroyed. In the phase of overcoming the period of "heroic" activity, the risk is that there will be a tendency to tiredness and renunciation. We have to react and regain our personal and professional strength and even the SERTOT must react. Because of this, it is with great pleasure that I introduce the volume 4-2020 Acta Biomedica Supplement - Advances in Orthopaedics, Traumatology and Rehabilitation - SERTOT. The vitality of our Scientific Society is demonstrated by its ability to publish scientific papers also in this particular period of the life. This is the first issue in 2020 but I am confident that our Society will publish also to the second one. SERTOT has always stimulated their members to send articles to the magazine focused on different orthopaedics and traumatologic topics. For these reasons, I am very happy that, also in this circumstance, contributions have arrived particularly numerous. A special thanks to the Deputy Editors Francesco Pogliacomi and Paolo Di Benedetto for the personal commitment and passion dedicated to the magazine and to the sponsors who have guaranteed the release of this journal in the past years and this year. Sincerely.

The current treatment of distal femur fractures includes locking plating and retrograde intramedullary nailing. These fractures are difficult to manage also for experienced surgeons, with results not always satisfactory. Reported nonunion rates now range from 0 to 34%. Factors associated with nonunion include comorbidities, such as obesity and diabetes, as well as the presence of open fractures, medial bone defects and comminuted fractures. This case report summarizes all of these assumptions and it concerns a 58 years old patient who underwent to 6 surgical procedures before to arrive to bone healing.

Introduction: the metaepiphyseal fractures of the proximal humerus represent 5% of all fractures and mainly affect elderly patients. The type of treatment remain controversial. This retrospective study aimed to evaluate the clinic and radiographic results of 23 patients affected by two or three fragments fractures of the proximal humerus with or without metaphyseal extension treated with antegrade intramedullary nailing., Materials and Methods: all patients were clinically evaluated using the "Constant score" (CS) and individual satisfaction was assessed with a visual scale (VS). Moreover, the fracture's healing process and the neck shaft angle (NSA) were assessed radiographically., Results: the mean follow-up was 72 months (24-120). Clinical evaluation and individual satisfaction were positive in most cases (mean CS 79,39 and VS 3,17). Worse results were observed in patients over 65 years., Discussion: among the different surgical options intramedullary nailing ensures good fracture stability and high consolidation rate. The entry point through the rotator cuff is of main importance as well as proximal nail positioning and choice of the locking screws length. In this study the functional results of the shoulder are worse in the elderly, who are supposed to have already a degenerated rotator cuff., Conclusions: antegrade intramedullary nailing should be considered a valid therapeutic option in this type of fractures. The surgical technique may influence functional results, as consequence of iatrogenic damage of the rotator cuff.

In recent years in the era of successful of total hip replacement, hip arthrodesis is rarely performed. The anatomy and biomechanics of an arthrodesed hip is altered, thus influencing the treatments strategies in case of fracture or nonunions. This case report describes the management and therapeutic solution for the treatment of subtrochanteric nonunion in a patient with hip arthrodesis. Satisfactory outcomes were finally obtained after a double surgical procedure.

Background and Aim of the Work: In adults, elbow dislocations are second in frequency after shoulder dislocations. They are often the result of a trauma due to accidental falls on the palm of the hand with the elbow flexed. In most cases this mechanism produces a posterior dislocation of the radius and ulna with respect to the humerus. The therapeutic approach was usually conservative in the past and it was characterized by manual reduction and plaster immobilization. More recently, as consequence of biomechanic and pathophysiology studies, the management of these injuries has gradually changed. The current trend is to immobilize the elbow only for few days and to evaluate its stability several times. In case of instability surgery may be indicated. The aim of this study was to assess the outcomes of simple stable elbow dislocations treated conservatively between january 2012 and december 2018., Methods: Twenty-six patients were included. All subjects underwent to a follow-up visit, in which clinical functional tests were performed in order to evaluate any stiffness in flexion-extension, prono-supination and instability in varus-valgus. In addition, patients were asked to complete three questionnaires (DASH, MEPS, SF-36) to evaluate how much the pathology interfered with ADL's., Results: Outcomes showed that prolonged immobilization increased stiffness in flexion and extension with the need of longer reabilithation. The recovery of prono-supination was instead always optimal. ADL's migth be influenced by the traumatic event and its management., Conclusions: Results of conservative treatment of simple elbow dislocation are generally satisfactory. A precise flow-chart of the patient management after trauma is essential in order to detect unstable lesions and.

Introduction: CoVID-19 (Coronavirus disease) is a worldwide infection which is causing millions of deaths. A significant number of elderly patients require hospitalization and develop serious and sometimes life-threatening complications. The aim of this study is to evaluate the preliminary impact (8 weeks) of CoVID-19, focusing on proximal femur fractures, analyzing data and results compared to the same period of 2019., Materials and Methods: From February 22nd to April 18th, 2020 we surgically treated 121 proximal femur fractures (61 in Piacenza; 60 in Parma, 16 male, 44 female, mean age 81.1). In the same period of 2019, we treated 169 proximal femur fractures (90 in Piacenza, 33 male, 57 female, mean age 81.9; 79 in Parma, 29 males, 50 female, mean age 80.2). We had 21/61 (34.4%) patients resulted positive for COVID-19 and 11/61 in Parma (18.3%), based on nasal-pharyngeal swab, chest CT scan and/or lung US findings., Results: The incidence of proximal femur fractures had a significant reduction during CoVID-19 spread in Piacenza and Parma. Authors have noticed an elevated number of deaths within 21 days after surgery. Piacenza: 4 cases in 2019 (4.4%) and 11 in 2020 (18.0%), of which 9 cases CoVID positive. In Parma in 2019 two deaths were encountered; in 2020 6 patients died and 5 cases were CoVID positive., Conclusion: In the first two months of the Italian epidemic, in the cities of Piacenza and Parma over 80% of deaths have occurred in patients over 70 years old. Even if preliminary, our study shows a significant increase in death in elderly patients surgically treated for proximal femur fractures, particularly in the Piacenza Hospital.

Background and Aim of Work: Musculoskeletal injuries are the most common cause of severe, chronic pain and physical disability for the majority of all sport-related injuries. Platelet-rich plasma is being used more frequently to promote healing of muscle injuries. We report a case of 39 years old non professional soccer player who came to our attention for a quadriceps muscle pain onset after kicking the ball during a match., Methods: Clinical and instrumental evaluation revealed a myotendinous junction rupture of the rectus femoris with retraction of 1.5 cm from the anterior inferior iliac spine. We decided to treat the patient with PRP ultrasound guided injections and a specific rehabilitation protocol., Results: Clinical evaluation 45 days following the end of the treatment showed the resolution of the pain and the full recovery of strength and range of motion. Muscle healing was documented by magnetic resonance imaging., Conclusions: Even if the role of PRP in muscle injury is not still clear, the result observed confirms that it could be used in the treatment of muscle lesions.

Background and Aim: Pelvic ring fractures represent a challenge for orthopaedic surgeon. Their management depends on patient's condition, pattern of fracture and associated injuries. Optimal timing for synthesis is not yet clear. The aim of this study was to define if surgical timing influenced clinic and radiographic outcomes following open reduction and internal fixation for Tile B and C fractures., Materials and Methods: 38 patients were included. Patients underwent a clinical examination with the Majeed Score, Iowa Pelvic Score and Orlando Pelvic Score. The radiographic assessment was performed according to Matta Pelvic Score. A statistical analysis of the data compared patients who were operated within 3 weeks (group 1) and those operated later (group 2)., Results: Both clinical and radiological outcomes were influenced by timing of surgery., Conclusion: Pelvic ring fractures interest many polytrauma patients and, therefore, their surgical orthopedic approach is frequently delayed as consequence of the severity of the associated clinical conditions. An early surgery of pelvic rong fractures allows a better quality of reduction and osteosynthesis.

Background and Aim of the Work: There is no consensus about indications for fibular osteosynthesis in extra-articular fractures of the distal tibia (DTF). This study analyses patients affected by DTF associated to fibular fracture and has the aim to define whether the level of fibular fracture has an influence on bone healing and consequently when its fixation is indicated., Methods: Eighty-seven patients were operated from January 2005 to December 2016. Inclusion criteria were: the presence of skeletal maturity, the absence of physical limitations before trauma and a type 43-A AO closed fracture. Clinical outcomes were evaluated using Olerud-Molander Ankle Score (OMAS) and the Disability Rating Index (DRI). Malrotation was also assessed as well as incidence of nonunion and malalignment through x-rays., Results: No differences in clinical scores were reported at follow-up between patients in which fibular fixation was performed (Group 1) in comparison with those in which this procedure was not executed (Group 2).  Nonunions were registered in 8 cases: four in Group 1 and four in Group 2. A statistically significant difference in incidence of external malrotation and valgus malalignment between the groups was documented, with a higher risk in patients of the second group., Conclusions: The level of fibular fracture is important to determine when the fixation of this bone is indicated. In supra-syndesmotic fractures osteosynthesis leads to a higher incidence of nonunions. Fibular osteosynthesis could prevent malrotation and malalignment and is advisable in distal metaphyseal fracture of this bone (trans- or infrasyndesmotic lesion) with syndesmotic injury.

Background and Aim: There is a wide debate about the number, diameter and length of the syndesmotic screw and necessity and timing for its removal. The aim of this study is to determine whether functional and radiological outcomes differ in patients operated for Weber type B and C ankle fractures who had syndesmotic screws removed (group 1) compared to those who did not (group 2). Furthermore, authors want to define if it is really necessary to remove this device and its correct timing., Materials and Methods: 90 patients were eligible for the study. The functional outcomes were analyzed 1 year after surgery using OMAS and AOFAS scores. Radiographic evaluation assessed the tibiofibular distance immediately and 12 months after surgery and fracture's healing., Results: Clinical and x-rays results were similar in both groups at follow-up., Discussion: Fractures with interruption of syndesmosis are lesions that, if not well treated, are complicated by joint stiffness, residual pain and post-traumatic osteoarthritis. Syndesmotic screw removal is not routinely performed, thus accepting the risk of rupture but avoiding a new surgery., Conclusions: Results observed suggest that syndesmotic screw removal is not necessary. If surgeon decide to remove this device correct timing is mandatory in order to obtain satisfactory long-term results.

Background and aim The incidence of hip osteoarthritis (OA) is increasing in parallel with the aging of the population. The aim of this study is to report the efficacy of an ultrasound-guided intra-articular (IA) hip injection of a single dose of high-weight hyaluronic acid (HA) (2500 kDa) at a follow-up of 12 months. Materials and Methods 226 patients older than 40 years of age affected by painful hip OA (Kellgren-Lawrence stage 1-2-3) were treated from January 2012 to December 2015 with viscosupplementation. Patients were clinically evaluated before injection (T0) and after 3 months (T3), 6 months (T6) and 1 year (T12) through the WOMAC scale and Harris Hip Score (HHS). Results During the follow-up period no patients underwent to hip surgery or need adjunctive IA injection of HA. No adverse effects were registered. An improvement in WOMAC and HHS was observed in all patients after treatment. Results showed that patients with grade 2 of osteoarthritis had the higher delta of change in the scores.  Discussion Ultrasound-guided with high weight IA HA injection could be a possibility of treatment in the symptomatic osteoarthritic hip. Subjects with a moderate grade of osteoarthritis (Kellgren-Lawrence stage 2) represent the group that could report the maximum benefits from viscosupplementation.

Osteoid osteoma is a benign bone neoplasm with a reported incidence of 2-3% among all bone primary tumors. Although it is a small and benign lesion, it is often cause of patient complaint and discomfort. It is generally characterized by a long lasting, unremitting pain that typically exacerbates at night, often leading to sleep deprivation and functional limitation of the skeletal segment involved, with a significant reduction of patient daily life activities and consequent worsening of the overall quality of life. Over decades, complete surgical resection has represented the only curative treatment for symptomatic patients. In the last years, new percutaneous ablation techniques, especially radiofrequency ablation, have been reported to be a safe and effective alternative to classical surgery, with a low complication and recurrence rate, and a significant reduction in hospitalization cost and duration. The aim of this article is to provide an overview about the radiofrequency thermal ablation procedure in the treatment of osteoid osteoma.

Objective: In a context of bone fragility, primitive and subsequent fractures are a growing problem in the industrialized countries where the mean age of the population is constantly increasing. Among the various factors that favor a fragility fracture, the most important is osteoporosis, a pathology that can be prevented through diagnostic screenings and treated by pharmacological and rehabilitative therapies. The aim of this study is to identify the subjects who are likely to have a higher risk of subsequent fractures of the trochanteric region through a retrospective radiographic evaluation of patients affected by low-energy trochanteric fractures and operated by intramedullary fixation between June 2013 and June 2015, so they can be targeted for prevention interventions., Materials and Methods: Three hundred and sixty-one patients yet alive were analyzed 2 years after surgery. Fifty-one (group 1), characterized by another contralateral trochanteric femoral fracture, were included. All subjects were retrospectively examined with the analysis of contralateral femur X-ray performed at the time of initial trauma in order to detect a condition of bone fragility and a predisposition to fractures by evaluating three radiographic indices (Singh index, Dorr's classification and Cortical Thickness Index). Patients of group 1 were compared to the other 310 patients (group 2) affected by isolated trochanteric fracture., Results: Group 1 had all radiographic indices worse than group 2., Conclusions: The results observed suggest that orthopedists can use radiographic indices, in particular Cortical Thickness Index, as a valuable, simple and inexpensive screening tool for prevention of recurrent osteoporotic fractures.

The knee is the intermediate joint of the lower limb and it allows the movement between the femur, tibia and patella. Under normal conditions there is a normal distribution of the load forces on these three articular components in both the static load and during ambulation. The understanding of anatomy and knee biomechanics is important for the gait analysis, the diagnosis of joint diseases and the design and development of prosthetic implants. In the last decades comprehension of knee physiology and kinematics has led to the introduction of a wide range of enhanced prosthetic implant designs for a variety of indications. There are a number of types of total knee arthroplasty implant designs, which are intended to offer the surgeon options for individual patients. The various choices imply that each specific problem has a corresponding implant that provides a reliable solution. However, until the current date, it has not been possible to produce a prosthetic design fully restoring the complex kinematics of the normal knee joint.

Background: Fifth metacarpal neck fractures (commonly named "boxer's fractures") are the most common metacarpal injuries and usually affect young active people. These lesions are mainly treated conservatively. Their surgical management, if indicated, is still a matter of debate. Different procedures have been described. The aim of this study was to evaluate the outcomes of 18 boxer's fractures which were synthesized with antegrade locked flexible intramedullary nailing., Materials and Methods: All patients, at a mean follow-up of 45 months, were clinically evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Patient Rated Wrist/Hand Evaluation (PRWHE). Active and passive range of motion (ROM) of metacarpo-phalangeal (MP), proximal and distal interphalangeal (PIP and DIP) joints and Total Active Motion (TAM), and grip strength were also analyzed. Apex dorsal angulation and axial shortening were radiologically measured preoperatively and at final follow-up., Results: Clinical and radiological results which were observed were satisfactory. No TAM and grip strength differences were recorded between the operated and healthy contralateral hand., Conclusions: According to the positive outcomes and the low rate of complications of this study, antegrade locked flexible intramedullary nailing can be considered a valid treatment option in boxer's fractures.

Background: The treatment of complex distal humerus fractures is challenging and is often associated with unsatisfactory results. Anatomic reduction and stable internal fixation is difficult to obtain, especially in elderly osteoporotic patients. For these reasons, total elbow arthroplasty (TEA) has recently evolved as a valid procedure in selected cases following these injuries. The aim of this study was to analyze outcomes of TEA for the treatment of complex distal humerus fractures in 20 low-demanding patients over 65 years of age., Materials and Methods: All patients, at a mean follow-up of 60 months, were evaluated clinically using the Mayo Elbow Performance Score (MEPS) and radiographically in order to assess the positioning of the prosthetic components and signs of loosening. Statistical analyses investigated the presence of clinical and radiographic variables as predictive factors of poor functional outcomes., Results: Similar MEPSs were observed in the affected and unaffected arm. Results were good or excellent in 90% of the patients, even if a high rate of complications (35%) was encountered. The development of postoperative complications and concomitant cognitive impairment and rheumatoid arthritis were predictive factors of unsatisfactory outcomes., Conclusions: According to the results observed, TEA can be considered as a valid treatment for complex fractures of the distal humerus in low-demanding patients older than 65 years of age, in which a stable fixation is difficult to obtain. Several variables may influence the final outcomes.

We describe the treatment of a 29 year-old professional motocross rider, who sustained a perilunate dislocation in his right wrist and a distal radius fracture and dorsal dislocation of his left wrist during a race. Both wrists were treated acutely during a single operating session. Surgery consisted in open reduction, k-wire fixation and mini-anchor repair of the scapho-lunate and luno-triquetrium ligaments on the right wrist, while closed reduction and percutaneous k-wire fixation was used in the left wrist. Follow-up at 6 months has shown satisfying radiological and functional outcomes in both wrists. The rider ultimately returned to motocross 5 months following surgery.

The Orthopaedic Rehabilitation Centre of Madagascar can be found in the city of Antsirabe. The health care facility is equipped with 2 thermal sources of bicarbonate water used for post-operative rehabilitation and for the ailment of chronic degenerative illnesses. The aim of this study, which derives from the cooperation between the School of Specialization in Thermal Therapy of the University of Parma and Antsirabe Orthopaedic Hospital, is to analyze the real properties of thermal waters utilized in this centre and to do an overview of its possible applications in this particular African context.

Background: Fractures in elderly are always a dramatic event and the healing is often not complete. In a context of bone fragility, repeated fractures are a growing problem in the industrialized world, in which the mean age of population is increasing. The aim of this study was to identify those general factors which may increase the risk of subsequent trochanteric fractures after an initial lesion., Materials and Methods: Three-hundred and thirty-one patients who underwent intramedullary fixation for trochanteric fractures between January 2012 and December 2013 were studied. Forty subjects yet alive (group 1), affected by a subsequent contralateral hip fracture, were compared with 202 patients (group 2) affected by isolated trochanteric fracture. Days of hospitalization before surgery, hospitalization, period of rehabilitation, type of discharge and comorbidities, that are reported in literature as possible risk factors for hip refracture, were analyzed. In addition, all patients were interviewed in order to assess if a therapy for osteoporosis was prescribed after the initial fracture and how their gait had been modified by fractures., Results: Days of hospitalization before surgery, hospitalization, period of rehabilitation and type of discharge were not predictive factors for subsequent fractures, as well as diabetes mellitus, hypertension and cardiac diseases. The presence of neurologic and respiratory diseases were associated to a higher risk of refractures, as well as the absence of specific medical treatment for osteoporosis., Conclusions: Neurologic and respiratory comorbidities and the absence of osteoporosis medical treatment are the variables associated to a higher risk of contralateral fractures. Physicians can do more in terms of prevention and strategies must consider these risk factors.

Background and Aim: Isolated coracoid process fractures are more frequent than what has formerly been believed. Delayed diagnosis or misdiagnosis are not infrequent as it is difficult to notice this injury using routine radiographic projections of the shoulder. In any event, more specific views are prescribed only when a fracture is suspected. The purpose of this study is to assess the outcomes of 9 cases of isolated coracoids fractures treated conservatively after being undiagnosed and discuss the reasons of these delayed diagnoses., Materials and Methods: Between January 1984 and June 2011, 9 out of 19 isolated coracoid fractures received a delayed diagnosis. There were 7 type I fractures and 2 type II. All patients were treated conservatively., Results: All fractures, except one, consolidated. The delay of the diagnosis was greater in type II lesions rather than in type I. Differences in clinical outcomes between affected and healthy side were minimal. Delayed diagnosis was overseen by the physician in 8 cases whereas in 1 case the patient underestimated the trauma and left the injury untreated., Conclusions: An isolated coracoid fracture should always be suspected after receiving a direct blow on the shoulder or after sustaining a forceful traction of the upper arm. In these events, specific radiographic projections should be performed in order to visualise the entire length of the coracoid process and to avoid oversight, delayed diagnosis or misdiagnosis. In isolated type I undisplaced fractures and in the majority of type II fractures, conservative treatment is indicated. (www.actabiomedica.it).

Isolated capitellar fractures are rare injuries accounting for only 1% of all elbow fractures. Type I or Hahn-Steinthal fractures require internal fixation to restore the anatomic integrity of the elbow joint. Many different fixation methods have been described and, independently of the method chosen, precise reduction is mandatory to maximize articular congruency and to diminish the potential for secondary osteoarthritis. The treatment and the outcome of two type I capitellar fractures are described in this study. One patient (April 1999) underwent open reduction and Kirschner wire fixation while the second patient (May 2004) underwent open reduction and Acutrak standard screw fixation. In both patients no complications occurred and normal elbow function was recovered. No signs of avascular necrosis (AVN), heterotopic ossifications and degenerative osteoarthritis were detected. We conclude that Acutrak screw fixation is a reliable method of treatment because it enables a good interfragmentary compression, earlier mobilization, faster functional elbow recovery, and metal work removal is rarely necessary.

Tibial plateau fractures are complex lesions capable of causing severe consequences if not appropriately treated. They are often the result of a high-energy trauma and, not rarely, are associated with significant soft-tissue and intra-articular injuries. Different therapeutic options can be managed in the treatment of these lesions. Minimally invasive surgery offers several advantages compared to other surgical techniques and allows, with less additional soft tissue damages, good reduction and stable fixation of the fracture. In this study we assessed the results of the combined arthroscopic and radioscopic assisted reduction and internal fixation of tibial plateau fractures in 18 patients affected by Schatzker type I, II, III, IV fractures. According to Hohl's and Rasmussen's grading system, 16 out of 18 patients scored a satisfactory result. We experienced no complications due to arthroscopy.

Aim of this study is to compare the different kinds of tendonitis in athletes using cryoultrasound therapy, lasertherapy CO2 and t.e.ca.r. therapy (transfert energetic capacitive and resistive). Forty five athletes were selected; they were all affected by severe insertional tendonitis of the Achilles tendon (15 of them), of the patellar tendon (15 of them) and of the epicondylar region (15 of them) during the last two months. They were divided into three groups. The first group underwent a treatment of 12 lasertherapy CO2 sessions, the second group 12 cryoultrasound therapy sessions and the last group 12 t.e.ca.r. therapy sessions. Each patient was registered by an independent observer according to the pain before (initial V.A.S.) and after treatment (final V.A.S.) using the analogic visual range from 0 (lack of pain) to 10 (unbearable pain) and the indicator of efficacy (difference between initial V.A.S. and final V.A.S./initial V.A.S.x 100). The obtained results were expressed as a difference between the two V.A.S. values and as a parameter of effectiveness (value ranging from 0 to 100) in order to correlate the initial condition of the patients with the performed physiotherapic treatment. The obtained V.A.S. score was submitted to statistic evaluation by analysis of variance through repeated measures, taking into consideration a value of p<0.05. Possible differences among the group of patients were shown by analysis of variance through one single way by comparison among groups. Every patient benefited from the treatment. Analyzing the initial and final V.A.S. values in the three groups, statistically significant variations emerged (p<0.05). A meaningful difference resulted among the different kinds of treatment; a marked difference was noticed between laser CO2 and cryoultrasound therapy (p<0.01). No statistically significant differences were observed between t.e.ca.r. and laser CO2 therapy or between t.e.ca.r. and cryoultrasound therapy. It must be admitted that the mean difference between initial and final V.A.S. is higher in the Cryoultrasound group (7.40), than in the Laser group (6.33) compared to t.e.ca.r. group (6.74). This result would explain a higher range of effectiveness in the Cryoultrasound group (85) compared to the laser CO2 (71.9 ) and t.e.ca.r. group (77.3). It can be asserted that cryoultrasound is a useful instrument for the physician working in the sports field. It offers advantages in comparison with laser CO2. It does not show significant differences with t.e.ca.r. therapy, although it shows a better mean range of effectiveness.

The diagnosis of osteoid osteoma, in usual localizations, is generally simple. In iuxta-articular localizations this tumor may be unrecognized and the diagnosis delayed. Injury has been sometimes correlated with the onset of symptoms and this can make the diagnosis even more difficult. We present a case of osteoid osteoma of the calcaneus iuxta-articular to the subtalar joint in a 17-year-old basketball player. He had a history of initial injury, ankle sprain during training, followed by pain and swelling. He was initially treated for lateral ligament lesion of the ankle with unsatisfactory results. After acute trauma the pain changed becoming chronic and mostly nocturnal disappearing when rofecoxib was taken. Standard x-ray didn't show the lesion. Nuclear Magnetic Resonance (NMR) and scintigraphic results were not well interpreted but these clinical changes and Computed Tomography (CT) images supported the diagnosis of osteoid osteoma. The complete resection of the bone lesion resolved all the symptoms and the histological report confirmed the suspected diagnosis.

The Authors, after a short analysis on biomechanics of the elbow during throwing in baseball, show the movements of the elbow during the different phases of the throw and the stabilizing action of the ulnar collateral ligament, flexor-pronator muscles of the wrist, anconeus and brachial triceps muscles. Aim of this study is the evaluation of the peak torque, total work and average power of the flexor-extensor and pronator-supinator muscles of the elbows in professional baseball players. Isokinetic test data show that a mayor peak torque in flexo-extension at power and resistance test in the pitchers compared to the strikers. Whereas the strikers show a higher peak torque in pronation at the resistance test. This may happen because during a baseball match the ball is hit many times by the bat and the pronator muscle of the wrist are notably stimulated and reinforced.

Developmental hip dysplasia (DDH) is characterized by an anomalous growth of the hipjoint. Without adequate treatment, the natural history of DDH is development of secondary osteoarthritis in adulthood. The correction of the deformities modifies the biomechanics of the hip, which is important in order to slow down the progression of osteoarthritis and maybe to prevent and postpone this development. The Bernese periacetabular osteotomy is a procedure which reorientates the acetabular articular surface. Several surgical approaches have been used to achieve the same effective osteotomy. No surgical approach represents "the optimum", with selection of appropriate exposure representing a balance of advantages and disadvantages. We used the ilioinguinal approach in 32 periacetabular osteotomies for acetabular dysplasia performed between 1996 and 2002. The operation was successful in 30 patients with acceptable operation time and blood loss and few complications. The advantages and disadvantages with the ilioinguinal approach as compared to other possibile incisions are discussed.

Forearm traumas are frequent and sometimes complex; soft tissue damages associated with bone lesions could be underestimated and so compromise the final result, in spite of a good reduction and osteosynthesis. Articular and iuxta-articular proximal radius and ulna fractures, which can be associated to radio-humeral dislocations in Monteggia lesions, are less frequent compared to diaphyseal fractures and can present a lot of therapeutical difficulties and a high rate of complications. These complications are avoided and reduced if the treatment is quick and focused on stable osteosynthesis and anatomical reduction of the fragments of the fracture and followed, as soon as possible, by rehabilitation. The authors present the 10 years experience of Parma Orthopaedics Institute with a follow-up of at least 12 months.
