Additional fixations for sliding hip screws in treating unstable pertrochanteric femoral fractures (AO Type 31-A2): short-term clinical results.

Background: To evaluate the utility of additional fixation methods and to suggest a method of reduction in the treatment of unstable pertrochanteric femur fractures with a sliding hip screw (SHS).

Methods: A retrospective study was performed on thirty patients with unstable pertrochanteric femur fractures, who were operated on with a SHS between September 2004 and September 2009 and were followed up for at least 6 months. The additional fixation devices were as follows; antirotation screw (21 cases), fixation of displaced fractures of the posteromedial bone fragment (cerclage wiring, 21 cases and screw, 2 cases) and trochanter stabilizing plate (27 cases).

Displaced avulsion fracture of medial meniscus posterior horn through the intercondylar notch in the patient without combined ligamentous injuries.

Avulsion fractures of the posterior horn of the medial meniscus are uncommon and must be differentiated from a loose body. The authors present a displaced avulsion fracture of the medial meniscus posterior horn through the intercondylar notch into the anteromedial compartment of the knee, which was treated by arthroscopic reduction and internal fixation using pull-out suture technique.

Correlation of synovial fluid leptin concentrations with the severity of osteoarthritis.

Leptin is known to play an important role in the pathophysiology of osteoarthritis (OA). This study investigated whether synovial fluid (SF) leptin level is related to the radiographic severity of OA and its role as a quantitative marker for the detection of OA. SF was obtained from 42 OA patients who underwent knee surgery and 10 who had no abnormality of articular cartilage during arthroscopic examination.

Arthroscopic all-inside repair of Palmer type 1B triangular fibrocartilage complex tears: a technical note.

Arthroscopic repair of peripheral dorso-ulnar triangular fibrocartilage complex (TFCC) lesions is now a preferred method. Both outside-in and inside-out techniques are commonly performed for repairing Palmer type 1B TFCC tear. But these techniques have disadvantages of making an additional skin incision to tie knots subcutaneously over the capsule.
