Objective: Statins stimulate bone formation by inducing the expression of bone morphogenetic proteins (BMP-2). The aim of our study was to investigate the effects of orally administered simvastatin on spinal fusion in rats.

Methods: Twenty rats were randomized into a spinal fusion group (SF) (n=10) or a spinal fusion and oral simvastatin administered group (SFS) (n=10).

[Overlooked primary hyperparathyroidism presented with fractures: case report].

In the present paper, we report a female patient with multiple cystic lesions of bone arising from the primary hyperparathyroidism and pathological femur and contralateral tibia fractures at the level of these cystic lesions (osteitis fibrosa cystica). The patient's history revealed that she was admitted to a medical center with vague symptoms such as sudden onset of dyspepsia, loss of appetite, myalgia, arthralgia, fatigue, and weight loss six years ago but no disease was diagnosed. Loss of appetite and loss of weight continued.

[Protective effects of melatonin on ischemia-reperfusion injury of skeletal muscle].

Objectives: In this study, we investigated the antioxidant protective effects of melatonin on skeletal muscles of Wistar albino-type rats with acute ischemia/reperfusion (I/R) injury.

Materials And Methods: Twenty-eight Wistar albino-type male rats weighing between 334 to 422 g were included in this experimental study. The rats were randomly allocated into three groups including sham, I/R and I/R + melatonin groups, respectively.

[Opening focal dome osteotomy in the treatment of varus gonarthrosis associated with medial laxity].

Objectives: We evaluated the short-term results of opening focal dome osteotomy in the treatment of varus gonarthrosis associated with medial laxity.

Patients And Methods: Seventeen knees of 16 patients with varus gonarthrosis associated with medial laxity (15 females, 1 male; mean age 51.6 years; range 45 to 58 years) were managed with opening focal dome osteotomy in our clinic between September 2003 and July 2006.

The "butterfly" suture technique for meniscal repair.

One of the important factors effecting meniscal healing is the strength of primary fixation obtained by repairing technique. From this perspective, it is important to choose the technique ensuring a higher primary fixation strength for meniscal repairs. We described a new technique for meniscal repair called "butterfly" technique using Viper device and hypothesized that high primary fixation strength can be obtained with this technique.

Comparison of intra-articular hyaluronic acid injections and mud-pack therapy in the treatment of knee osteoarthritis.

Objectives: Conservative treatment should be tried prior to surgical treatment in knee osteoarthritis. This study was designed to evaluate the short-term effects of mud-pack therapy on pain relief and functional improvement in knee osteoarthritis in comparison with intra-articular hyaluronic acid injections.

Methods: The study included 23 patients who were diagnosed as having knee osteoarthritis according to the ACR (American College of Rheumatology) criteria, and had complaints lasting for more than three months.

Osteoid osteoma of the trapezium: case report.

Osteoid osteoma is a benign bone tumor representing approximately 10% of all benign bone tumors. Although osteoid osteoma of the long bones and carpus is frequent, the location in the trapezium is extremely rare. We found only one other report in the literature regarding osteoid osteoma of the trapezium.

[Total hip arthroplasty using the anterolateral minimally invasive approach].

Objectives: We evaluated the clinical and radiographic results of total hip arthroplasties (THA) performed with the minimally invasive anterolateral (MIA) and standard anterolateral (SA) approaches.
