OBJECTIVES Hallux valgus is a common orthopaedic condition affecting elderly people. Grading the severity of the condition commonly involves obtaining measurements from radiographs, which may not be feasible or necessary in some clinical or research settings. Recently, a non-invasive clinical assessment tool (the Manchester scale), consisting of four standardized photographs, has been developed...

BACKGROUND Previous studies have indicated that the demands placed on the medial ulnar collateral ligament of the elbow when it is subjected to valgus torque during throwing exceed its failure strength, which suggests the necessary dynamic contribution of muscle forces. We hypothesized that the flexor-pronator mass assists the medial ulnar collateral ligament in stabilizing the elbow against va...

Valgus moments on the knee joint during single-leg landing have been suggested as a risk factor for anterior cruciate ligament (ACL) injury. The purpose of this study was to test the influence of isolated valgus moment on ACL strain during single-leg landing. Physiologic levels of valgus moments from an in vivo study of single-leg landing were applied to a three-dimensional dynamic knee model, ...

BACKGROUND Knee valgus load during sports movement is viewed as an important predictor of non-contact anterior cruciate ligament injury risk, particularly in females. Formulating movement strategies that can reduce valgus loading during these movements therefore appears pertinent to reducing anterior cruciate ligament injury rates. With this in mind, the current study examined the relationship ...

BACKGROUND Application of plane geometry to the study of bunion deformity may represent an interesting and novel approach in the research field of hallux valgus. For the purpose of contributing to development of a different perspective in the assessment of hallux valgus, this study was conducted with three objectives: a) to determine the position on the intersection point of the perpendicular b...

Hallux valgus deformity combined with dorsal dislocation of the second metatarsophalangeal joint is frequently observed in rheumatoid arthritis cases. However, hallux valgus deformity without lesser toe dislocation is also seen in rheumatoid cases. Dislocated second toe cause the loss of the lateral support on the hallux, suggesting the importance to confirm the state of lesser toe MTP joint wh...

BACKGROUND A new radiographic view was proposed to evaluate the coronal plane alignment of the hindfoot under weightbearing conditions. METHODS We studied 46 feet of individuals with normal appearing asymptomatic feet. On the antero-posterior roentgenogram using this new method, the line from the top of the sustentaculum tali to the lateral-inferior end of the posterior articular surface of t...

INTRODUCTION Base wedge osteotomies are a wellestablished surgical indication for patients presenting with hallux valgus deformities. Proximal osteotomies are indicated for severe deformities in cases when the intermetatarsal angle is greater than 15 degrees (Landsman and Vogel, 1992). Numerous base wedge procedures have been identified to correct hallux valgus deformity, all requiring internal...

AIM Outcome of primary total arthroplasty for osteoarthritis of the knee with valgus deformity. MATERIALS AND METHODS Between 2005 and 2007, 28 primary total knee replacements were performed for osteoarthritis of the knee with valgus deformity. 21 cases were women and 7 men with a mean age of 66.6 years (extremes 54-81). The clinical and radiological evaluations were done considering the knee...
