RESUMO

BACKGROUND: Percutaneous alcoholization with phenol by electrostimulation guidance for the treatment of Morton's neuroma is proposed to determine a permanent chemical neurolysis. METHODS: 115 patients for 125 Morton's neuromas were treated. Ten patients were affected by multiple neuromas. Visual Analogue Scale and AOFAS score were used for the clinical assessment. RESULTS: The mean follow-up was 8,3 years. The pre-alcoholization VAS was 85.84 ± 12.00, while at follow-up scored 28.85 ± 31.35, showing a significant decrease improving in 113/125 cases (90.4%). Treatment was considered successful with a reduction of the VAS value superior to 50% in 89 out of 125 patients (71.2%). The mean overall AOFAS score at -up was 85.09 ± 13.41. CONCLUSIONS: Needle-electrode guided percutaneous alcoholization is an outpatient, minimally invasive procedure with low rate of complications. Better results of those obtained with traditional conservative treatments and comparable with those reported with other alcohols injections or surgical nerve excision were observed. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

BACKGROUND AND AIM OF THE WORK: Osteoarthritis will become even more common in the near future since the average life span is steadily growing. Pain and loss of function are the main complaints reported by patients, inevitably leading towards a worsened daily life performance. New modern techniques have been developed with advanced cell based therapies. Mesenchymal stem cells (MSC) have the inner ability to mature into different types of cells depending on the stimuli they undergo. This technique has already been proven successful in the knee and, with this retrospective study, we would like to assess its feasibility in the hip joint. METHODS: 6 consecutive patients affected by hip osteoarthritis were treated by intra-articular injection of autologous adipose-derived MSC between June 2017 and June 2018. Our study included only patients with constant hip pain resistant conservative treatment and OA graded 0-2 on the Tonnis grading scale. All 6 patients were evaluated in the preoperative setting and at the 6 months post-operative mark. RESULTS: The HHS showed an improvement from the pre-operative baseline mean value of 67.2±3.4 to the 84.6±6.3 post-operative value. Moreover, the WOMAC score dropped from a baseline score of 36.3±4.7 to 19.8±3.4 at 6 months' post-op follow up visit. CONCLUSIONS: MSC Lipogems is a fairly easy technique. No adverse effects were recorded in our experience. Preliminary results showed a positive outcome according to all the grading systems used in this study even though a longer follow up is needed to validate this technique.

RESUMO

A case of a 71-year-old man with femoral and tibial osteolysis and severe metallosis of the knee, resulting from abrasive wears of the metal components of a unicompartmental knee arthroplasty, that leaded to the rupture of the femoral component of the prosthesis is reported. An unicompartmental prosthesis, in a varus knee, was implanted in 2007. In March 2017, the patient felt that his knee was becoming increasingly unstable with pain and increasing disability. At clinical evaluation there was an effusion, 110° of flexion and - 10° of extension and a slight instability at the varus/valgus stress tests. BMI was 35. In a CT scan performed in June 2017 no signs of alteration were evident, but an X-Ray performed in January 2018 showed a rupture of the femoral component. A revision surgery was performed in February 2018. At the time of revision surgery, the synovitis and the metallosis were evident. A cemented total knee arthroplasty was performed. Samples of the fluid and surface did not show any bacterial growth. Histological examination confirmed the presence of a massive metallosis. The patient had a satisfactory rehabilitation. According to the literature, metallosis and rupture of the prosthetic components due to polyethylene wear after UKA is a common complication. In our case report the elevated BMI and varus knee accelerated the wear of the polyethylene. The aim of this case report is to enhance how an appropriate diagnosis (clinical and radiographic) and early treatment can lead to a successful result.

RESUMO

INTRODUCTION: The intricate linkage between Freezing of Gait (FoG) and postural control in Parkinson's disease (PD) is unclear. We analyzed the impact of FoG on dynamic postural control. METHODS: 24 PD patients, 12 with (PD + FoG), 12 without FoG (PD-FoG), and 12 healthy controls, were assessed in ON state. Mobility and postural control were measured with clinical scales (UPDRS III, BBS, MPAS) and with kinematic and kinetic analysis during three tasks, characterized by levels of increasing difficulty to plan sequential movement of postural control: walk (W), gait initiation (GI) and sit-to-walk (STW). RESULTS: The groups were balanced by age, disease duration, disease severity, mobility and balance. During STW, the spatial distribution of COP trajectories in PD + FoG patients are spread over medial-lateral space more than in the PD-FoG (p < .001). Moreover, the distribution of COP positions. in the transition between sit-to-stand and gait initiation, is not properly shifted toward the leading leg, as in PD-FoG and healthy controls, but it is more centrally dispersed (p < .01) with a delayed weight forward progression (p < .05). In GI task and walk task, COM and COP differences are less evident and even absent between PD patients. CONCLUSION: PD + FoG show postural control differences in STW, compared with PD-FoG and healthy. Different spatial distribution of COP trajectories, between two PD groups are probably due to a deficit to plan postural control during a more demanding motor pattern, such as STW.

RESUMO

Atypical femoral fractures are often associated with prolonged bisphosphonate use. The American Society for Bone and Mineral Research (ASBMR) has set the diagnosis criteria for atypical subtrochanteric and diaphyseal femoral fractures by classifying them according to their major and minor criteria. Prolonged bisphosphonate use is correlated with AFF, but the pathogenetic mechanism that causes this kind of fracture has not been defined yet. We describe simultaneous bilaterally femoral fractures in a 76-year-old woman.

RESUMO

There is a complex interplay between the cells of the immune system and bone. These inter- actions are not only mediated by the release of cytokines and chemokines but also by direct cell-cell contact. Studies of intracellular signaling mechanisms in osteoclasts have revealed that numerous immunomodulatory molecules are involved in the regulation of bone metabolism. Recently, it was proposed that immunoreceptors found in the immune cells are also an essen- tial signal for osteoclasts activation, along with receptor activator of NF-icB (RANK) ligand (RANKL). Collectively, these and similar observations regarding cross-regulation between the immune and skeletal systems constitute the field of osteoimmunology. Here we briefly high- light core areas of interest and selected recent advances in this field.

RESUMO

AIM OF THE STUDY: To evaluate the efficacy of plates and screws with angular stability in osteosynthesis of fractures of the distal radius. MATERIALS AND METHODS: We analyzed 52 patients undergone surgery for fracture of the distal radius at the Clinica Ortopedica dell'Università di Trieste; in half of the patients osteosynthesis was provided using Synthes' LCP plates, in the other half we utilized a multidirectional and angular stable plate ("Aptus Radius" by Medartis). Mean follow-up was 28 ± 10 months, patients were evaluated with DASH score (disability of arm shoulder and hand) and the modified Gartland Werley score. RESULTS: There were no significant differences between the two groups in terms of joint function, motility, volar and radial mean inclination. CONCLUSIONS: Based on clinical and radiological results using angular stability plates must be considered as the method of election in the treatment of fractures of the distal epiphysis of the radius; in particular, thanks to the broader technical capabilities that they allow, are particularly indicated in unstable fractures.

RESUMO

AIM OF THE STUDY: To compare unicompartmental knee arthroplasty with "all poly" tibial component and "metal back" from a clinical and functional point of view. MATERIALS AND METHODS: We evaluated prospectively 50 patients who underwent unicompartmental knee replacement at the Orthopedic Clinic of the University of Trieste. Patients were split into two groups (A and B); in patients from group A has been implanted a Mitus prosthesis (Link) with "all poly" tibial component, in patients from Group B has been implanted an Allegretto prosthesis (Zimmer) with a "metal back" tibial component. The mean follow-up was 36 months. All patients were evaluated using the Knee Society Score. RESULTS: The mean preoperative Knee Society Score (objective and functional) was found to be respectively 48 and 49 or the group A and group B; post-operative score was found to be of 95 and 94 respectively for Group A and group B. The average post-operative ROM was 125 degrees (range, 85-140 degrees) for group A and 130° (range 90°-145°) for group B. CONCLUSIONS: No differences were found between implants with "all poly" tibial component (thickness to be used must be greater than 6 mm) and those with the "metal back". We believe that to achieve positive results over time is important the carefully selection of the patients and the accurate positioning of components.

RESUMO

The hallux rigidus, especially in advanced stage, has always been a challenge as regards the surgical treatment. Over the years there have been various surgical techniques proposed with the aim of relieving pain, correcting deformity and maintain a certain degree of movement. For some years we have addressed the problem with the replacement metatarsophalangeal joint arthroplasty with Reflexion system. As far as our experience we have operated and monitored 25 patients (18 females and 7 males) of mean age 58.1 years, operated with this technique from June 2008 to June 2011. It reached an average ROM of 72° (extension and flexion 45° and 27°) with a good functional recovery in 8 patients, and this articulation was good (50° - 40°) in 12 patients and moderate in 5 with a articular range from 40°- 30°. The clinical results, according to our experience, appear to be favorable, as even patient satisfaction is complete.

RESUMO

AIM OF THE STUDY: The injury of the radial nerve is not uncommon in humeral shaft fractures. These lesions may be of different types and levels and their treatment changes depending on traumatic characteristic. The authors present a case report of a patient affected by a closed shaft humeral fracture, consequence of an high energy trauma, associated with motor palsy of the radial nerve in which an open surgical revision was performed. The nerve appeared medially displaced and entrapped within the fracture fragments and the fibrous tissue around the lesion and showed signs of posttraumatic suffering without disruption. The nerve was repositioned in its anatomical site after neurolysis and intramedullary nailing of the humeral fracture. The fracture healed after 4 months with full recovery of motor function of the radial nerve.We believe that, in shaft fractures of the humerus with radial nerve deficits, it is imperative to perform surgical exploration of the conditions of the radial nerve itself, in order to obtain a recovery of its functionality.

RESUMO

Breast cancer is the most common form of cancer in women and the leading cause of cancer death in American women, with over 207,090 new cases of invasive breast cancer in women and about 39,840 deaths from breast cancer in 2010. Current therapies for breast cancer usually have variable effectiveness with high toxicity to normal tissues, and breast tumours often develop metastasis and drug resistance. Therefore, searching for effective regimens with minimal side effects remains the top priority in breast cancer research. The objectives of this study were to evaluate the effects of tanshinone II from a Chinese herb, Salvia miltiorrhiza, on the growth of breast cancer cells type MCF-7 and MDA-MB-231.

RESUMO

The receptor activator of nuclear factor-kappaB ligand (RANKL), its signaling receptor RANK, and its natural decoy receptor OPG are members of the tumour necrosis factor (TNF) and TNF receptor superfamily and are best known for their essential role in controlling osteoclastogenesis. RANKL in bone has also been shown to serve as a chemoattractant for cancer cells, thu explaining the tropism of certain cancers such as breast and prostate cancer to preferentially metastasize to bone. Here, we will discuss the important role of RANKL and its possible role in the management of bone loss in patients with breast cancer.

RESUMO

The average age of population is increasing in parallel with the worldwide incidence of fractures of the proximal femur; among all of them, 45% is represented by pertrochanteric fractures. Many other significant co-morbidity and even mortality are associated to this fractures (osteoporosis, malnutrition, decreased physical activity, reduced visual acuity, neurological deficits, asthenia, balance disorders and altered reflexes). Due to osteoporosis, the greater frequency of these fractures  occurs to elderly women. Among a total of 630 patients with pertrochanteric fracture treated in the Orthopedic Clinic of Trieste from January 2003 to December 2011, 16 cases were about Cut-out (5 males and 11 females). The mean follow-up after the revision surgery was 18 months. The aim of the study was to understand if in pertrochanteric fractures the best osteosynthesis can be guaranteed by the placement of an intramedullary nail or by positioning of plate and screws. It was established that, using intramedullary nail, the best target is to have a good positioning of the method of synthesis with a "Tip-Apex Distance" (TAD) of less than 25 millimeters.

RESUMO

A frequent problem in Orthopedic surgery is represented by periprosthetic fractures in Total Hip Arthroplasty (THA). The incidence of this pathology has interested 1,5% in primary THA and till 6-8% in revision prosthesis during last 10 years. About this contest, the authors performed a study on 24 patients (6 males; 18 females) surgically treated for periprosthetic femoral fracture at the Orthopedic and Traumatologic Clinic, University of Trieste, Italy, in the period from January 2006 to December 2011. Periprosthetic fractures were classified following guide-lines of the Vancouver Classification System. Even the choice of treatment was based on Vancouver Classification System, on patient clinical conditions and patients age.

RESUMO

PURPOSE OF REVIEW: The increased age observed in most countries, with the associated higher rates of chronic illnesses and cancer, and a diffuse sedentary lifestyle, will increase the number of patients with clinically relevant anabolic resistance, sarcopenia and its complications. The need for solutions to this major health issue is, therefore, pressing. RECENT FINDINGS: The metabolic derangements and other consequences associated with sarcopenia can be slowed or even prevented by specific nutritional interventions. New evidence is available about the efficacy of omega-3 fatty acid dietary supplementation to improve protein metabolism and counteract anabolic resistance through indirect effects. Studies show that the anabolic stimuli from substrates (e.g. amino acids or proteins), hormones (e.g. insulin) and/or physical activity in skeletal muscle can be enhanced by long-term fish oil administration. SUMMARY: The review of data from recent studies on this topic suggests that dietary omega-3 fatty acid supplementation, in association with an anabolic stimulus, could potentially provide a safe, simple and low-cost intervention to counteract anabolic resistance and sarcopenia. This intervention may contribute to prevent cachexia and disabilities. Supplementation should be given in the earlier stages of sarcopenia (e.g. precachexia). Further research should, however, be performed to better understand the mechanisms involved and the best dosage and timing of administration.

RESUMO

The management of proximal humeral fractures is still controversial and no single treatment has been unanimously accepted. This paper focuses on displaced two-part fractures to describe the minimally invasive fixation device known as Helix Wire and to propose precise indications for its use, partly on the basis of our previous study of its mechanical properties. Thirty patients with nondisplaced and displaced humeral neck fractures were treated with implantation of a Helix Wire between January 2005 and September 2005. Clinical and radiographic follow-up was carried out at 1, 2, 6 and 12 months. Clinical and functional assessment was performed using the Constant-Murley score. The results at 1 year after surgery were excellent in 7 cases (23.3%), good in 14 cases (46.6%), fair in 8 cases (26.6%) and poor in 1 case (3.3%). On the basis of our precise indications, elderly patients with nondisplaced or displaced two-part fractures of the proximal humerus may achieve good results with minimally invasive implantation of the Helix Wire.

RESUMO

Introducción: El abordaje para una artroplastia total de cadera (ATC) mediante miniincisión se ha comenzado a utilizar en forma progresiva con el propósito de disminuir la morbilidad, acelerar la recuperación de los pacientes sin aumentar los riesgos y reducir el tiempo de internación. Sin embargo, el abordaje mínimamente invasivo podría aumentar el tiempo de cirugía o de internación, y afectar la orientación de los componentes y la seguridad del procedimiento. El objetivo de este trabajo es comparar los resultados preliminares perioperatorios del primer grupo de 34 pacientes operados en nuestra institución mediante incisión mínima (grupo I) con instrumental convencional frente a un grupo control de 26 pacientes con similares condiciones intervenido mediante abordaje posterolateral de Gibson (grupo II) por dos cirujanos. Materiales y métodos: Se utilizó una incisión promedio de 8 cm en el GI y de 20 cm (promedio) en el GII. Resultados: No hubo diferencias estadísticamente significativas entre ambos grupos en la pérdida sanguínea ni en las complicaciones. En cambio, sí las hubo en el tiempo operatorio (GI: 88,3 frente a GII: 101,1 minutos) y en los días de internación (GI: 2,8 frente a GII: 3,9 días) a favor de los pacientes operados por miniincisión. En el análisis de los resultados radiográficos sólo se observaron diferencias significativas en el promedio de lateralizacióndel centro de rotación horizontal en favor de los pacientes operados mediante incisión convencional (GI: 4,46 mm frente a GII: 2,17 mm). Conclusiones: En este estudio la ATC primaria mediante miniincisión resultó un procedimiento seguro, que disminuyó los tiempos de cirugía y de internación sin aumentar las complicaciones.
