Femoral component rotation is important in total knee arthroplasty to optimize patellofemoral and tibiofemoral kinematics. More recently, the epicondylar axis has been cited as definitive landmark for femoral rotation. However, there are few studies support validity of this rotational its effect on articulations. In current study, a was done 11 knees from cadavers. The were tested with various rotations 5° internal external referenced posterior condyles. Each acted own control. actively...
Residual symptoms resulting from recurrent episodes of inversion-type ankle sprains may be attributed to a decreased neuromuscular response the peroneal or tibialis anterior muscles, thereby increasing probability for reinjury. The purpose this study was examine electromyographic (EMG) time and muscles in sudden plantar flexion/inversion stress chronically functional unstable normal ankle. Subjects consisted 13 athletically active individuals (five males eight females, mean age = 19.2 +/-...
High tibial osteotomy is a valuable option for patients with varus gonarthrosis. To avoid difficulties closing-wedge osteotomies, medial opening-wedge high osteotomies have been advocated.Opening-wedge good in highly active gonarthrosis who would like to delay or prevent progression total knee arthroplasty without activity restrictions.Case series; Level of evidence, 4.Twenty consecutive were treated using the Puddu plate and allograft bone graft prospective study (14 men 6 women; average...
The current work sought to quantify pronation of the first metatarsal relative second and proximal phalanx great toe metatarsal.
Supination weakness commonly occurs after a distal biceps repair. The goal of this study was to identify factors that could influence postoperative supination strength through full arc forearm rotation.Fifteen patients were prospectively studied and underwent repair using posterior approach; cohort compared with randomized selection 17 anterior subjects. All magnetic resonance imaging (MRI). Quantitative MRI analysis determined the insertion site angle tendon supinator fat content. measured...
Background: Hallux valgus (HV) is a triplanar deformity of the first ray including pronation metatarsal with subluxation sesamoids. The purpose this study was to investigate if tarsometatarsal fusion (modified Lapidus technique), without preoperative knowledge measured on weightbearing computed tomographic (CT) scans, changed and determine reduction sesamoids correlated changes in pronation. Methods: Thirty-one feet 31 patients HV who underwent modified procedure had at least 5-month...
Background: The radial tuberosity contributes to the biceps supination moment arm and elbow flexion moment. purpose of our study was compare impact a cortical bone trough versus an anatomic repair on measurements forearm force efficiency. Our hypothesis that would decrease height, native arm, efficiency compared with repair. Methods: isometric were measured in ten matched pairs cadaveric upper limbs. After testing, geometry proximal aspect radius reconstructed use stereophotogrammetry. All...
Human exposure to blast waves without any fragment impacts can still result in primary blast-induced traumatic brain injury (bTBI). To investigate the mechanical response of human and identify mechanisms bTBI, a three-dimensional finite element head model consisting scalp, skull, cerebrospinal fluid, nasal cavity, was developed from imaging data set female. The partially validated subjected five intensities anterior, right lateral, posterior directions at stand-off distance one meter...
This study sought to determine whether several metatarsophalangeal (MTP) fusion techniques require complete immobilization or if some level of weight-bearing could be recommended after surgery. A comparison synthetic composite actual bone was included in order examine the validity testing conditions.Four MTP modalities were tested models: unlocked plating, locked crossed lag screws, and an plate with a single screw. Stiffness calculated then used find two most rigid constructs; load failure...
There is no consensus in the foot and ankle literature regarding how to measure pronation of first metatarsal patients with hallux valgus. The primary purpose this study was compare 2 previously published methods for measuring a novel 3-dimensional measurement determine if different measurements are associated each other.Thirty who underwent modified Lapidus procedure their valgus deformity were included study. Pronation measured on weightbearing computed tomography (WBCT) scans using α...
Abstract The mechanical success of a total knee replacement demands stable patellar tracking without subluxation and, tracking, in turn, can depend largely on the medial‐lateral forces restraining patella. Patellar button medialization has been advocated as means reducing subluxation, and experimental evidence shown femoral component rotation also affects medial—lateral forces. Surgeons have choices must frequently make intra‐operative decisions concerning placement because anatomical...
