Abstract Background The purpose of this study was to analyze differences in geometrical properties the proximal femur and predict occurrence basicervical fractures through a comparative femoral neck patients undergoing hip structural analysis (HSA). Methods All with who were at least 65 years old admitted our hospital between March 2017 December 2019 eligible for study. During period, 149 (FNF)...

BACKGROUND Currently it is uncertain how to define osteoporosis and who to treat after a hip fracture. There is little to support the universal treatment of all such patients but how to select those most in need of treatment is not clear. In this study we have compared cortical and trabecular bone status between patients with spinal fractures and those with hip fracture with or without spinal f...

The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) w...

The management of hip instability as a consequence of septic arthritis in childhood is difficult. Ilizarov hip reconstruction is a double-level femoral osteotomy with the objective of eliminating hip instability, through a proximal valgus-extension-derotation osteotomy and a distal varization-lengthening osteotomy for mechanical axis correction and equalization limb length. Ilizarov hip reconst...

Most patients with thoracic ossification of the posterior longitudinal ligament (OPLL) exhibit delayed recovery of gait dysfunction after spinal injury. The hybrid assistive limb (HAL) is a new robot suit controlling knee and hip joint motion by detecting very weak bioelectric signals on the surface of the skin. This study is to report the feasibility and benefits of patient-assistive HAL walki...

We examined the hypothesis that structural features of the iliotibialis lateralis pars postacetabularis (ILPO) in guinea fowl allow this large muscle to maintain equivalent function along its anterior-posterior axis. The ILPO, the largest muscle in the hindlimb of the guinea fowl, is a hip and knee extensor. The fascicles of the ILPO originate across a broad region of the ilium and ischium post...

A computer-controlled display of random dots was used to study perceptions of depth. In this display, a field of stationary random dots surrounded a rectangular area in which random dots moved with uniform velocity in a single direction. The boundaries of this rectangle did not move. When dot motion was perpendicular to the longer boundary of the rectangle (occluded motion), the rectangle seeme...

Hand-assisted laparoscopic nephrectomy (HAL-N) and nephroureterectomy (HAL-NU) were introduced to bridge the gap between open and laparoscopic surgery. This newer technique has the benefits of both laparoscopic and open surgical approaches but has a shorter learning curve and decreased operative time compared to laparoscopic surgery. A review of our 2-year experience showed that for the sevente...

BACKGROUND Total hip arthroplasty involves division of the joint capsule, which can cause receptor damage, affecting postural stability and increasing the risk of falls. The aim of this study was to determine whether postural stability can be disturbed by total hip arthroplasty from a postero-lateral approach. MATERIAL AND METHODS Static balance was quantified with the use of a two plate tens...
