BACKGROUND A quantitative and accurate measurement of the range of hip joint flexion (RHF) is necessarily required in the evaluation of disordered or artificial hip joint function. This study aimed to assess a novel method to measure RHF more accurately and objectively. METHODS Lateral radiographs were taken of 31 supine men with hip joints extended or flexed. Relevant angles were measured di...

[Purpose] The Hybrid Assistive Limb(®) (HAL(®)) robot suit is a powered exoskeleton that can assist a user's lower limb movement. The purpose of this study was to assess the effectiveness of HAL(®) in stroke rehabilitation, focusing on the change of the sit-to-stand (STS) movement pattern and standing posture. [Subjects and Methods] Five stroke patients participated in this study. Single leg HA...

BACKGROUND: The modified Dall approach is a modified anterolateral approach with osteotomy of the anterior part of the greater trochanter. OBJECTIVES: We aimed to evaluate the adequacy of the modified Dall approach by measuring leg length discrepancy and evaluating offset discrepancy using postoperative radiographs. METHODS: Of 103 cases of total hip arthroplasty (THA), 22 patients (mean age, 6...

Limb-length discrepancy, to one degree or another, is a problem that must be reckoned with after total hip arthroplasty (THA). It must be addressed as both a clinical issue for patients and, unfortunately, a potential medicolegal problem. Although a small limb-length discrepancy may cause no symptoms or may not be perceived, a large limb-length discrepancy may cause nerve palsy, low back pain, ...

objectives: this study was designed to evaluate the effectiveness of a modified floor reaction ankle foot orthosis (frafo) design on gait performance in children with cerebral palsy. methods: eight children with cerebral palsy wore a modified frafo bilaterally for six weeks. motion analysis was used to assess the immediate effectiveness of the orthosis on improving gait and also following six w...

BACKGROUND Total hip arthroplasty with subtrochanteric shortening osteotomy is widely performed for high hip dislocation. However, suboptimal leg length discrepancy correction and nonunion of the osteotomy site remain concerns. Although total hip arthroplasty using trochanteric osteotomy without subtrochanteric osteotomy was introduced, cemented implants have been more commonly used than contem...

Leg-length discrepancy after total hip arthroplasty can pose a substantial problem for the orthopaedic surgeon. Such discrepancy has been associated with complications including nerve palsy, low back pain, and abnormal gait. Careful preoperative measurement and assessment, as well as preoperative and postoperative patient education, are important factors in achieving an acceptable result. Howev...

The weighing records of 18 crossbred females with average live weight of 14.7 ± 3.14 kg were analyzed to study the relationship of the growth of crossbred hair sheep with some zoometric measures. The weight was established and took the measures thoracic perimeter, cannon perimeter, body length, neck length, hip amplitude, ischial amplitude, withers height and croup height. All parameters were s...

PURPOSE To evaluate hip parameters such as vertical centre of rotation (VCR), horizontal centre of rotation (HCR), femoral offset, and leg length after total hip arthroplasty (THA) using the Nanos short-stem prosthesis. METHODS Medical records of 73 men and 74 women aged 25 to 92 (mean, 63) years who underwent THA using the Nanos short-stem prosthesis by a single surgeon were reviewed. Prior ...
