Effectiveness of Ilizarov external fixation in elderly patients with pilon fractures.

Background: Pilon fractures are associated with soft tissue complications such as skin necrosis, and deep infections have been reported very often. This study retrospectively compared the treatment effects of Ilizarov external fixation and of internal fixation methods in elderly patients with pilon fractures.

Methods: A total of 37 patients >60 years old with pilon fractures (AO classification type 43) were investigated.

Effectiveness of distal tibial osteotomy with distraction arthroplasty in varus ankle osteoarthritis.

Background: In highly active older individuals, end-stage ankle osteoarthritis has traditionally been treated using tibiotalar arthrodesis, which provides considerable pain relief. However, there is a loss of ankle joint movement and a risk of future arthrosis in the adjacent joints. Distraction arthroplasty is a simple method that allows joint cartilage repair; however, the results are currently mixed, with some reports showing improved pain scores and others showing no improvement.

Comparison of Atypical and Osteoporotic Femoral Shaft Fractures in the Elderly: A Multicenter Study.

Background: In atypical femoral fractures, owing to the high rates of complications and delayed healing that accompany the plate fixation, the most favorable treatment is intramedullary nailing. Although there is insufficient evidence, plate fixation is chosen due to anterolateral bowing of the femur. This study compared the bone healing time and rates of complications in atypical femoral shaft fractures and osteoporotic femoral shaft fractures.

Reconstruction of a chronically ruptured Achilles tendon using an internal brace: a case report.

Background: We reconstructed a chronically ruptured Achilles tendon and the associated scar tissue using braided polyblend polyethylene sutures (FiberWire; Arthrex Inc.; Naples, FL, USA) and anchors.

Case Presentation: A 68-year-old Japanese man, who was being treated for right Achilles tendinosis, felt pain in his Achilles tendon when walking and started to find plantar flexion of his ankle joint difficult.

Cut-Off Value of Medial Meniscal Extrusion for Knee Pain.

. Medial meniscal extrusion (MME) has attracted attention as an index of knee pain in conjunction with clinical symptoms that could be more useful than the diagnosis of knee osteoarthritis on X-ray. However, the size of MME that would cause knee pain has not been clarified.

Comminuted distal humeral fracture treated using the Ilizarov technique in a patient with rheumatoid arthritis and osteoporosis.

The goal of treatment for distal humeral fractures in patients with rheumatoid arthritis (RA) is to obtain sufficient bone union and good elbow function. However, treating comminuted distal humeral fractures in patients with RA and osteoporosis is challenging. We present the case of a 58-year-old woman with RA and osteoporosis who suffered a comminuted distal humeral fracture and was successfully treated with the Ilizarov technique.

Effects of risedronate alone or combined with vitamin K2 on serum undercarboxylated osteocalcin and osteocalcin levels in postmenopausal osteoporosis.

Risedronate decreases osteoporotic fracture incidence; however, its effects remain unclear in elderly osteoporotic patients. Vitamin K mediates carboxylation of osteocalcin (OC), and high undercarboxylated osteocalcin (ucOC) levels indicate vitamin K deficiency and increased osteoporotic fracture risk. We aimed to evaluate the effects of risedronate alone or combined with vitamin K2 on serum ucOC, OC, and incidence of vertebral fractures in elderly osteoporotic patients.

Osteosarcoma of the patella: a case report.

We present a rare case of osteosarcoma involving the patella. A 30-year-old Japanese woman first consulted our out-patient clinic with a 2-year history of knee pain. Radiographs showed an enlargement of the patella with irregular distribution of both osteolytic and sclerotic lesions.

Bilateral stress fracture of the fibulae and periostitis of the tibiae.

Objective: This study describes a unique case of bilateral stress fractures of the fibulae and provides a literature review.

Clinical Presentation And Intervention: A 16-year-old female badminton player presented with pain around the bilateral distal lateral legs. She had mild bilateral varus deformity at the knee joint, and the bilateral ankles showed valgus deformity in standing posture.

Pigmented villonodular synovitis of the elbow treated with the Tsuge wide joint exposure technique.

Pigmented villonodular synovitis (PVNS) is a benign, locally aggressive disease of the synovium; its cause remains unclear. The most frequently involved joint is the knee, followed by the hip, ankle, wrist, and shoulder. Pigmented villonodular synovitis of the elbow joint is rare.

Unusual association between enchondroma and Camurati-Engelmann disease: a case report.

This case report describes an enchondroma of the distal phalanx of the right little finger in a 37-year-old woman with Camurati-Engelmann disease. Curettage of the tumor and artificial bone grafting were performed in May 2004. Surgical treatment resulted in a good clinical outcome with no evidence of recurrence at 5-year follow-up.

Infiltration by macrophages and lymphocytes in transplantable mouse sarcoma after irradiation with high-intensity focused ultrasound.

Background: High-intensity focused ultrasound (HIFU) therapy offers great promise for the treatment of cancer. The histological changes, including the antitumor immunological response, after HIFU treatment was examined in soft tissue sarcoma.

Materials And Methods: Sarcoma 180 cells were injected subcutaneously in mice.

Tenosynovitis with rice body formation in a non-tuberculosis patient: a case report.

In this report, we present a 68-year-old man with rice body formation in the flexor tendon sheath of the fingers without any inflammatory diseases such as tuberculosis or rheumatoid arthritis. The patient visited our institute in March 2004 with a one-month history of swelling and pain of the right distal forearm. Laboratory data were within normal limits, and the rheumatoid factor was negative.

The sonodynamic antitumor effect of methylene blue on sarcoma180 cells in vitro.

Background: Sonodynamic therapy (SDT) is a promising methodology for cancer treatment. Methylene blue (MB) is a phenothiazine dye that is widely used in clinical practice and can be administered intravenously.

Materials And Methods: The sonodynamic antitumor effect of 1, 10 and 100 microM MB on sarcoma180 (S180) cells was investigated in vitro.

Sonodynamic effects of lomefloxacin derivatives conjugated with methoxy polyethylene glycol on sarcoma 180 cells.

Background: Sonodynamic therapy (SDT) is a promising methodology for cancer treatment. Lomefloxacin hydrochloride (LFLX) has been reported to have sonodymamic antitumor effects.

Materials And Methods: We synthesized LFLX derivatives conjugated with methoxy polyethylene glycol (PEGylated LFLXs) and investigated their ultrasonically induced antitumor effects.

Curettage with pasteurization in situ for grade 1 chondrosarcoma - long-term follow up study of less invasive surgical procedure.

Background: In the treatment of grade 1 chondrosarcoma of long tubular bones, a wide excision with replacement by a metal prosthesis has been widely used. However, postoperative function of the affected extremity has occasionally been problematic.

Case Report: In two cases of grade 1 chondrosarcoma, a 54-year-old man with a lesion in the mid humerus and a 17-year-old woman with the lesion in the proximal femur, we performed curettage with pasteurization in situ.

Antitumor effect of acridine orange under ultrasonic irradiation in vitro.

Background: Sonodynamic synergistic antitumor therapy is a promising new methodology for cancer treatment.

Materials And Methods: To determine the antitumor effects of ultrasound (US) in the presence of acridine orange (AO), 1.0 microg/ml solution of AO was tested as a sonodynamic compound against sarcoma 180 cells in vitro.

Discal cyst associated with myxoid change and apoptosis of herniated disc materials: a case report.

Discal cyst is a lumbar intraspinal cyst communicating with intervertebral disc, and previously reported series described the wall of these cysts as consisting of dense fibrous connective tissue. We report a 29-year-old Japanese male with discal cyst showing unusual histological features. Clinical symptoms in the current case as well as imaging features including discography were similar to those previously reported.
