A new pathway to classification of complex hand injuries: a clinical pilot testing using a new method of assessment.
All existing classifications, which are based on the severity of hand injuries, are being referred to facets of variety of hand injuries in general. A clear picture of all consequences of hand injuries would be apparent, if any kind of injury mechanism and occurrence of an injury would be identified and academically captured. Predictions regarding return to the former occupation and rehabilitation time would be possible with further study; 102 patients with different hand injuries were engaged in a pilot project using a specifically designed assessment sheet to achieve this purpose in the framework of a retrospective clinical testing within 1 year. ⋯ Furthermore, the mean DASH equivalents of one category were compared to the mean Hand Injury Severity Scoring (HISS) scores in order to get an initial idea of information on the degree of severity. A first impression of the potential of this assessment sheet has been obtained with regard to the above. With further study, we could evaluate the assessment sheet and try to create a classification of the grade of severity as well as prognostic values like return to the former occupation and rehabilitation time.

Effect of depressive symptoms on perceived disability in patients with chronic shoulder pain.
Psychological distress may be an important determinant of perceived disability in patients with chronic musculoskeletal disorders. We evaluated the relationship between depressive symptoms and perceived disability in patients with chronic shoulder pain and quantified the contribution made by depression to perceived disability. ⋯ Level 2, prospective cohort study, prognostic study.

Functional outcome of limb salvage surgery with mega-endoprosthetic reconstruction for bone tumors.
The use of a mega-endoprosthesis has become the method of choice for reconstruction after bone tumors. In this study, we sought to determine the functional outcome and complications associated with mega-endoprosthesis. ⋯ Mega-endoprosthetic reconstruction in limb salvage provides good functional outcome in patients with bone tumors.

Wear patterns of tibiofemoral articulation in osteoarthritic knees: analysis and review of literature.
Osteoarthritis is a degenerative joint disease characterized by progressive erosion of the articular cartilage. The sites of erosion of articular cartilage have been reported, but no explanation for this particular pattern has previously been suggested. ⋯ In osteoarthritis of the knee joint, the middle third of both the femoral and tibial articular surfaces is most commonly involved in wears, followed by anteromedial and posterolateral compartments both for tibial and femoral surfaces. The wear patterns in the ACL-deficient knee changes due to altered loading characteristics.

Viscoelastic adaptation of tendon graft material to compression: biomechanical quantification of graft preconditioning.
The tensile viscoelastic behaviour of tendon tissue is of central biomechanical importance and well examined. However, the viscoelastic tendon adaptation to external compression, such as when a tendon graft is fixated with an interference screw, has not been investigated before. Here, we quantify this adaptive behaviour in order to develop a new method to mechanically precondition tendon grafts and to better understand volumetric changes of tendinous tissue. The hypothesis of this study was that under compressive loads, tendon grafts will undergo a temporary volumetric (and therefore diametric) reduction, due to the extrusion of water from the tendon. ⋯ The viscoelastic behaviour of hamstring tendon grafts under pressure allows preconditioning of the grafts for reduction of volume and diameter and therefore to drill a smaller bone tunnel, retaining more of the original bone. At the same time, the collagen content of the transplant is preserved and a tight fit of the transplant in the bone tunnel achieved.
