BACKGROUND Infection of a hip prosthesis is one of the most severe complications encountered in orthopedic practice. Two-stage reconstruction using an antibiotic-impregnated cement spacer has become a popular procedure for the treatment of this condition. However, there are some disadvantages with the use of antibiotic-loaded cement, including low(More)
The aim of this study was to quantitatively assess the echo intensity of the supraspinatus muscle and compare magnetic resonance imaging and ultrasound findings for 27 patients (12 women, 15 men, 65.8 ± 11.5 y). Tear size and fatty infiltration were determined by magnetic resonance imaging; five stages were assigned based on Goutallier's classification.(More)
We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. The area at which the patient experienced spontaneous shoulder(More)
INTRODUCTION A periprosthetic humeral fracture is rare after shoulder arthroplasty, and such cases have considerable problems. Patients with this kind of fracture are often complicated by osteopenia, other types of severe disease, or are elderly. Surgical treatment of this fracture type carries some risk, and surgeons may be unsure about the most(More)
Stress fractures of the first rib are uncommon, and few reports have described the occurrence of this injury in overhead-throwing athletes. Furthermore, although there have been a few reports of first rib stress fractures on the throwing side in baseball players, fractures on the nonthrowing side are very rare. Here, we report 2 cases of first rib stress(More)
Ultrasonography (US) is a non-invasive method which can assess not only solid tissue organs but also soft tissues such as tendons and nerves. However, it has not been fully understood that US is a useful tool for the depiction of periarticular structure. We compared the diagnostic accuracies between US and magnetic resonance imaging (MRI) in the patients(More)
A collarless, proximally porous-coated type of Spongiosa Metal II hip prosthesis was used for cementless total hip arthroplasty in 52 hips, and 48 hips were followed and assessed during a mean follow-up period of 6.3 years (minimum 5 years). There were 8 hips (16.7%) that had stress shielding, and 2 hips (4.2%) that had thigh pain. In terms of stability,(More)
BACKGROUND Night pain is a particularly vexing symptom in patients with rotator cuff tear. It disturbs sleep and decreases quality of life, and there is no consensus regarding its etiology. Based on arthroscopic surgical observations of synovitis around the rotator interval or capsule surface in rotator cuff tear, we hypothesized that blood flow from the(More)
We evaluated the clinical and radiographic results of primary total hip arthroplasty for 81 dysplastic hips (71 patients) using cementless Spongiosa Metal II cups (ESKA Implants, Lübeck, Germany). The mean follow-up period was 6.4 years (minimum 5 years), and the preoperative mean Japanese Orthopaedic Association hip score had improved from 45.2 to 87.4(More)
