Total hip arthroplasty (THA) in congenital high grade hip dislocation often represents a problematic issue. Reviewing their selected cases and literature data, authors focus on some key points for this demanding surgery. Most important steps are acetabular positioning and surgical approach (exposure and release).We used two different cups, the Zweymuller and the Wagner cup, with good primary stability. A Conus stem (Wagner) or an Alloclassic stem (in less displastic femoral shape) were used.We always performed this surgery as a one step procedure.In the same cases a shortening femoral osteotomy was performed to allow refractory reduction.Possible complications are discussed.

COX-2 specific inhibitors (coxibs) have become a popular treatment for musculoskeletal disorders given that the incidence of gastrointestinal side effects is lower with these drugs than with traditional non-steroidal anti-inflammatory drugs. The aim of this review is to discuss the results of animal studies investigating the role of coxibs in the healing of soft tissues. MEDLINE was searched (years 2001-2009) for studies analyzing the effect of coxibs on the healing of soft tissues. There are relatively few data in the literature suggesting that coxibs can impair soft tissue healing and the data existing have the limitation of having been generated in animal studies. In fact, the method of administration and the doses used make it difficult to translate these results to the clinical setting. Short-term use of coxibs following lesions to ligaments or tendons remains a prudent choice. Traditional anti-inflammatory drugs are a safer treatment for patients with a high cardiovascular risk. These drugs should, however, be evaluated carefully with regards to gastrointestinal events and their still poorly defined effect on tissue healing.

The paper explores the use of open source geographic information system (GIS) applied to firms. Most data available in a company have a spatial dimension and even decisions in marketing and management often have a spatial dimension. The paper is focus on illustrating the variegated opportunities for an open source GIS based strategy for firms. We argue that open source GIS are today as good as its proprietary competitors, and under certain circumstances, they are a superior alternative to their proprietary counterparts. A GIS based strategy for firms, as any other new application of geographical knowledge, it is a prospect of a new area for geography studies. This paper can be considered an initial essay on the role that geographers can play in spatial analysis applied to business strategy. The application is an example of applied geography supporting firm strategies and it has the purpose to identify spatial customer potentials for a specific infrastructure, the inland terminal of Guasticce (Italy).

Partial-thickness rotator cuff tears are a challenge for shoulder surgeons. There is still no standard treatment protocol. The recent introduction of new arthroscopic techniques and a better grasp of pathogenic mechanisms along with a greater functional demand from patients, have led to the need for a thorough analysis of the problem. This paper analyses the literature in order to simplify the approach to treating partial-thickness rotator cuff tears.

The aim of this study was to document the incidence of postoperative shoulder stiffness (SS) after arthroscopic rotator cuff repair and evaluate the role of risk factors for its development. Seventy-five consecutive patients that underwent arthroscopic rotator cuff repair were included. The incidence of postoperative SS was prospectively investigated and the presence of 20 potential risk factors was documented retrospectively. The incidence of post-operative SS was 10.4%. All patients were women, and sex was significantly associated to pathology development (p=0.0067). The presence of gastroesophageal diseases was found to be significantly associated with post-operative SS development (p=0.0046). A significant association between the occurrence of post-operative SS and the presence of gastroesophageal diseases was identified. This finding, not yet reported in literature, deserves further investigation. The incidence of postoperative SS fell among previously reported ranges, with females significantly more affected than men.
