Influence of Femoral Implant Alignment in Uncemented Total Hip Replacement Arthroplasty: Varus Insertion and Stress Shielding.

Background: The influence of varus insertion of femoral implants in uncemented total hip replacement arthroplasty (THR) remains unclear. Thus, in this study, we retrospectively assessed the clinical impact of uncemented THR with femoral implants that were inserted in varus on the basis of radiological findings.

Materials And Methods: The study participants included 89 patients who underwent uncemented THR for 106 joints and were followed-up for >3 years.

Mid-Term Clinical Results of VerSys Hip System (Zimmer) Uncemented Total Hip Replacement Arthroplasty.

Unlabelled: Recent reports suggest that uncemented total hip replacement arthroplasty (THR) results in favorable short- to mid-term clinical results. In the present study, we assessed the mid-term clinical results of VerSys Hip System uncemented THR at our hospital.

Materials And Methods: We studied patients who received THR using VerSys Hip System and who could be followed-up more than 3 years.

Treatment for Trochanteric Fracture of the Femur with Short Femoral Nail: A Comparison between the Asian Intramedullary Hip Screw (IMHS) and the Conventional IMHS.

Introduction: We usually use short femoral nails for the treatment of trochanteric fracture of the femur. In this retrospective study, we investigated and compared the clinical results of the conventional intramedullary hip screw (IMHS) and the Asian IMHS, which is a redesigned version of the former.

Materials And Methods: The subjects were 42 patients; 21 treated with the Asian IMHS and 21 were treated with the conventional IMHS.

Conservative Treatment for Fracture of the Proximal Femur with Complications.

Unlabelled: We retrospectively compared two groups of patients with hip fractures and severe complications. One group had been treated surgically; the other group had been treated conservatively to prevent worsening of general status, with transfer to wheelchair as soon as possible. This study aimed to determine if early prognosis after conservative treatment would be worse than that following surgical treatment.

Split Fracture of the Posteromedial Tubercle of the Talus: Case Report and Proposed Classification System.

We describe a rare case of a fracture of the medial tubercle of the posterior process of the talus in a 16-year-old male athlete who fell during basketball practice. The patient presented to our orthopedic clinic when pain and swelling had persisted despite 2 weeks of anti-inflammatory medication and rest. Computed tomography and magnetic resonance imaging scans revealed a fracture of the posteromedial tubercle of the talus and a small amount of retained fluid in the joint.

Influence of the Medial Knee Structures on Valgus and Rotatory Stability in Total Knee Arthroplasty.

Background: Precise biomechanical knowledge of individual components of the MCL is critical for proper MCL release during TKA. This study was to define the influences of the deep MCL and the POL on valgus and rotatory stability in TKA using cadaveric knees.

Methods: This study used six fresh-frozen cadaveric knees.

A case report of rapidly progressing cauda equina symptoms due to rheumatoid arthritis.

Although rheumatoid involvement of the lumbar spine is relatively rare, we report a patient with rapidly progressing cauda equina symptoms due to rheumatoid diskitis. A 72-year-old woman was admitted to our hospital because of motor weakness below the iliopsoas muscle and sensory disturbance beneath the level of L2. Plain X-ray films, computed tomography, and magnetic resonance imaging demonstrated destruction of the L2/3 intervertebral disc and endplates with subluxation of the facet joints.
