Cross-cultural adaptation and multi-centric validation of the Italian version of the Achilles tendon Total Rupture Score (ATRS).

Purpose: The purpose of this study was to translate the Achilles tendon Total Rupture Score (ATRS) into Italian and establish its cultural adaptiveness and validity.

Methods: The original version of the ATRS was translated into Italian in accordance with the stages recommended by Guillemin. A web-based survey was developed to test the construct validity of the Italian ATRS.

Roentgen stereophotogrammetric analysis: an effective tool to predict implant survival after an all-poly unicompartmental knee arthroplasty-a 10 year follow-up study.

Purpose: The main purpose of the present study was to determine long-term implant fixation of 15 unicompartmental knee arthroplasty (UKAs) with an all-poly tibial component using Roentgen stereophotogrammetric analysis (RSA) at a mean 10-year follow-up. The secondary purpose was to investigate whether the progressive loss of implant's fixation correlates with a reduction in Knee society score (KSS).

Methods: Fifteen non-consecutive patients with primary knee osteoarthritis received a UKA with an all-poly tibial component were assessed using KSS scores pre-operatively and post-operatively and RSA on day 2 after surgery, then at 3, 6, and 12 months and yearly thereafter.

Hip painful prosthesis: surgical view.

Painful hip prosthesis is the most feared immediate and remote complication of a primary implant and usually represents the failure of one or more therapeutic moments. In cases of aseptic implant failure, the causes invoked may be represented by an incorrect indication, the quality of materials, local and general condition of the patient and especially from a bad joint biomechanics. In cases of septic loosening, however, the cause of failure to be found in the location of pathogens within the implant.

Arthroscopic second generation autologous chondrocytes implantation associated with bone grafting for the treatment of knee osteochondritis dissecans: Results at 6 years.

Purpose: The aim of this study was to analyze the clinical outcome obtained with arthroscopic second generation autologous chondrocyte implantation (ACI) associated with bone grafting for the treatment of knee osteochondritis dissecans (OCD) at medium term follow-up.

Methods: Thirty-four knees affected by symptomatic OCD grade III or IV on the ICRS (International Cartilage Repair Society) scale were treated and prospectively evaluated at 12, 24 months of follow-up, and at a final mean 6 ± 1 years of follow-up. The mean age at treatment was 21 ± 6 years.

Second-generation arthroscopic autologous chondrocyte implantation for the treatment of degenerative cartilage lesions.

Purpose: Degenerative cartilage lesions present a negative joint environment, which may have a negative effect on the process of cartilage regeneration. The aim of this study is to analyze the clinical outcome obtained with the treatment for isolated degenerative knee cartilage lesions by second-generation arthroscopic autologous chondrocyte implantation (ACI).

Methods: Fifty-eight consecutive patients affected by focal degenerative chondral lesions of the femoral condyles and trochlea were treated by second-generation arthroscopic ACI.

Alumina-on-alumina total hip replacement for femoral neck fracture in healthy patients.

Background: Total hip replacement is considered the best option for treatment of displaced intracapsular fractures of the femoral neck (FFN). The size of the femoral head is an important factor that influences the outcome of a total hip arthroplasty (THA): implants with a 28 mm femoral head are more prone to dislocate than implants with a 32 mm head. Obviously, a large head coupled to a polyethylene inlay can lead to more wear, osteolysis and failure of the implant.

Extracorporeal shock waves stimulate osteoblast activities.

The extracorporeal shock wave therapy (ESWT) is an extensively applied treatment for musculoskeletal disorders because it promotes bone repair. The aim of this study was to evaluate the direct effect of ESWT on murine osteoblasts to clarify the cellular mechanism that leads to the induction of osteogenesis. Osteoblasts in culture flasks were treated with ESWT pulses (500 impulses of 0.

Hip fracture in a patient affected by transient osteoporosis of the femoral head during the last trimester of pregnancy.

Few cases of hip fracture in pregnant women affected by transient osteoporosis of the femoral head have been reported in the literature, but its real incidence seems to be underestimated. During pregnancy, osteoporosis manifests itself with an insidious onset of hip pain and limp without any trauma or infective episode in clinical history. Its clinical course is characterized by spontaneous recovery a few weeks to several months after delivery.

Assessment of the initial stability of the Symax femoral stem with EBRA-FCA: a multicentric study of 85 cases.

We report a study of 85 Symax femoral stems that were followed at regular intervals with radiographs at 6, 12, 24 and 36 months. The radiological migration of each stem was measured using the computer-assisted EBRA -FCA method. In 30 cases in which the EBRA method did not provide a complete measurement another computer-assisted method (Roman version 1.

Bone healing induced by ESWT.

It has been at least two decades since the introduction of Extracorporeal Shock-Wave Treatment (ESWT) for the treatment of non-unions; despite conflicting opinions in the literature, it is recently achieving good results also in acute fractures. This paper reports Authors' clinical experience with electromagnetic shock-waves in the treatment of delayed unions and fresh fractures. Nonunion cases experienced remarkable successful results at an average of 8-10 weeks after ESWT; high success rate is been also found for the acute fractures.

Surgical approach to bone healing in osteoporosis.

Osteoporotic fractures represent one of the most common cause of disability and one of the major voice in the health economic budget in many countries of the world. Fragility fractures are especially meta-epiphyseal fractures, in skeletal sites with particular biomechanic characteristic (hip, vertebrae), complex and with more fragments, with slow healing process (mineralization and remodeling) and co-morbidity. The healing of a fracture in osteoporotic bone passes through the normal stages and concludes with union of the fracture although the healing process is prolonged.

Wound necrosis after total knee arthroplasty.

Quickly evolutive skin necrosis and deep infection after total knee arthroplasty (TKA) are not uncommon. Several predisposing factors, such as immunosuppression, malnutrition, steroid use, rheumatoid arthritis, multiple scars, and vascular disease can be involved in the onset of wound complications, as well as long tourniquet time and early knee flexion. Skin necrosis after TKA can be treated in different ways, including local wound care, debridement, and soft tissue coverage with muscle or skin grafts.

Shock waves in the treatment of stress fractures.

In soccer players, lower extremity stress fractures are common injuries and are the result of repetitive use damage that exceeds the intrinsic ability of the bone to repair itself. They may be treated conservatively but this may cause long-term complications, such as delayed union, muscle atrophy and chronic pain. Stress fractures that fail to respond to this management require surgical treatment, which is also not without risks and complications.

Spontaneous bilateral fracture of patella.

Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism.

Nora's lesion. Clinical and therapeutic considerations.

In this article we report a case of bizarre paraosteal osteochondromatous proliferation (BPOP), also known as Nora's lesion, arising on the distal phalanx of the fifth finger of the hand in a young-adult subject. In this paper, we discuss the possible therapeutic programme related to the grade of severity of the clinical features and underline the rarity of this lesion and the difficulty of diagnosis, which is exclusively histological.
