The aim of this paper was to examine the macroscopic and microscopic characteristics of the paratendineous tissues (paratenon, epitenon and endotenon) of the calcaneal tendon to better understand their role in the pathogenesis of “tendinopathy”. Ten non-embalmed legs from cadavers were used. Histological and immunohistochemical studies were done at the(More)
Femoral head necrosis (FHN) is a progressive pathology due to the failure of blood supply to the proximal femoral epiphysis, with consequent necrosis of the sub-chondral bone and collapse of the articular cartilage and loss of congruity between the head and the acetabulum. Borrowing the biological and mechanical principles from the vascularized fibular(More)
The expansion of myeloid derived suppressor cells (MDSCs), a suppressive population able to hamper the immune response against cancer, correlates with tumor progression and overall survival in several cancer types. We have previously shown that MDSCs can be induced in vitro from precursors present in the bone marrow and observed that these cells are able to(More)
We present the results of treatment of 100 patients (72 men, 28 women) by the Ilizarov method of bone transport using circular (55) and monolateral external fixators (45). A total of 26 femurs (18 monolateral, 8 circular) and 74 tibias (49 circular, 25 monolateral) was examined. There were no significant differences between the circular fixator and the(More)
BACKGROUND The survival of patients with tumors around the shoulder treated with extra-articular resection, the rates of reconstructions-related complications, and the function of the shoulder cannot be estimated because of limited available data from mainly small published related series and case reports. METHODS We studied 54 patients with tumors around(More)
Simultaneous bilateral presentation of psoas abscess with prosthetic joint involvement is extremely rare. A 68-year-old woman presented to us with bilateral dull aching groin pain of 6 months' duration, which flared up in the past month, associated with pyrexial symptoms. She had undergone bilateral hip replacements in the past with uneventful recovery. MRI(More)
Chondroblastoma (CB) is a rare benign tumor that occurs most commonly in the second decade of life. No studies on CB in adulthood have been reported. Our purposes were to report a single-institution experience on CB in adults and to discuss the clinical and imaging findings, type of treatment, oncologic and functional outcomes. All patients diagnosed and(More)
To analyze the clinical and radiographic characteristics, treatment, and outcome of patients with elbow osteoblastoma. We present 13 patients (7 males and 6 females; mean age, 28 years) diagnosed and treated for an elbow osteoblastoma from 1975 to 2012. Mean follow-up was 29 months (range 12–60 months). Clinical presentation, imaging, surgical treatment,(More)
BACKGROUND Proximal humeral fractures in four or even only three parts, with metaphyseal hinge distances of <8 mm, represent a serious and widely debated problem. Reduction is complex and plating is often instable, especially in elderly patients. Failures, sometimes involving necrosis of the head, are frequent. Hemiarthroplasty has long been used for 3- or(More)
BACKGROUND AND AIM OF THE WORK the treatment of acute type III acromio-clavicular Rockwood dislocations is still a matter of discussion in orthopaedic surgery. The purpose of this study, retrospective and comparative, is to evaluate the long-term results of two different surgical techniques of temporary stabilization using K-wires with and without tension(More)
