BACKGROUND Chiropractors use a variety of supine and prone leg checking procedures. Some, including the Allis test, purport to distinguish anatomic from functional leg length inequality. Although the reliability and to a lesser extent the validity of some leg checking procedures has been assessed, little is known on the Allis test. The present study mathematically models the test under a variet...
The existing methods of assessing limb lengthening during total hip arthroplasty (THA) are prone to error because the measurements are not parallel to the limb lengthening axis. In order to address this, we designed a caliper to estimate limb lengthening during THA and evaluated its accuracy compared with our previous device, the straight caliper. Limb lengths were measured in 100 patients. The...
Resultant center-of-pressure (CP) displacements result along mediolateral (ML) and anteroposterior (AP) axes from strategies mobilizing hips and ankles, respectively, and thus, should be largely influenced by the angles between the feet. To assess this relation and the effects of foot position on postural performance, 9 healthy young adults were tested. The main results, as the forefeet are spr...
Hip resurfacing is being performed more frequently in the United Kingdom. The possible benefits include more accurate restoration of leg length, femoral offset and femoral anteversion than occurs after total hip arthroplasty (THA). We compared anteroposterior radiographs from 26 patients who had undergone hybrid THA (uncemented cup/cemented stem), with 28 who had undergone Birmingham Hip Resurf...
Recent genome-wide (GW) scans have identified several independent loci affecting human stature, but their contribution through the different skeletal components of height is still poorly understood. We carried out a genome-wide scan in 12,611 participants, followed by replication in an additional 7,187 individuals, and identified 17 genomic regions with GW-significant association with height. O...
INTRODUCTION Proper imaging with radiographs plays an important role in preoperative planning and also assessing postoperative radiographic results. One of the major aims of any kind of lower limb corrective surgery such as corrective osteotomy or total knee arthroplasty, is restoration of the mechanical axis of the limb [1]. To achieve this, one needs to be able to assess the existing axis, pl...
Intramuscular fat (IMF) content has been identified as an important factor in determining the quality of pork. Previous studies have suggested that IMF deposition may be associated with the presence of the halothane (HAL) gene. This study aimed to evaluate the effect of the HAL gene on IMF deposition in crossbred pigs of commercial lines, which were killed at a slaughterhouse under official ins...
Objective: Femoral neck fractures mostly occurs due to high-energy trauma in young population and management differs compared elderly. Different geometric parameters the hip joint can play a role fracture morphology regarding age. Present study aims compare between elderly Materials methods: 45 patients with isolated femoral included study. Patients were divided into two age; group 1 (younger t...
The ROBODOC system was designed to address potential human errors in performing cementless total hip replacement. The system consists of a preoperative planning computer workstation (called ORTHODOC) and a five-axis robotic arm with a high speed milling device as an end effector. The combined experience of the United States Food and Drug Administration multicenter trial and the German postmarke...
HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not.
