Objectives: To compare the clinical results of osteosynthesis with plate and screws versus anterograde locked intramedullary nail in fractures of the distal third of humeral diaphysis.
Material And Methods: 184 patients with fractures of the distal third of humeral diaphysis were included in a prospective study. 82 patients underwent open reduction and internal fixation with plate and screws (Group 1), while in 102 cases, closed reduction and osteosynthesis with locked intramedullary nail was performed (Group 2).
Objectives: In some total knee arthroplasty cases, the usual medial parapatellar approach does not allow the appropriate patellar eversion and the desired exposure of the knee joint. Partial disinsertion of the patellar tendon doesn't substantially improve the surgical exposure and can lead to extensor apparatus weakening and complete secondary ruptures, while the V-Y quadricipital plasty leads to post-op immobilization of the knee, which delays the functional rehabilitation, with negative impact on the range of motion. The tibial tubercle osteotomy, however, allows an extension of the approach in total knee arthroplasty, without endangering the quadricipital extensor apparatus.

Background: When the primary tumor is unknown, the biopsy and the histopathological examination (associated with immunohistochemistry and molecular profiling) will identify the type and subtype of the tumor and, if possible, the site of origin. The classification in type and subtype will allow to assess the prognosis and to indicate the most appropriate therapeutic approach.
Aim: Identification of the unknown primary tumor by biopsy and immunohistochemistry from the femoral bone metastasis, the clinical results and the survival rate after osteosynthesis ± cement stabilization of the lesion.
Objective: To assess long-term outcomes of osteocartilaginous transplantation for non-degenerative lesions of hyaline articular cartilage in the knee, by performing minibiopsies from the transplanted area and examining them histopathologically.
Patients And Methods: Forty-four patients with post-traumatic cartilage injuries of the bearing surfaces of the knee were enrolled in a prospective study, that included treatment with autologous osteocartilaginous grafts at the level of the lesion, "second look" arthroscopy and targeted minibiopsies at one year and five years postoperatively (six minibiopsies per patient). The collected tissue fragments were examined by optic microscopy.
