TypeV Pauwels angle>50°, accompanied by anterior dislocation a obturator dislocation of the femoral head. (I)Type I: Pauwels angle is <30°, and shows no dislocation of the femoral head. (II)Type II: Pauwels angle is between 30°–50° and shows no dislocation of the femoral head. (III)Type III: Pauwels angle is >50° and shows no dislocation of the femoral head. (V)Type V: Pauwels angle is >50° and accompanied by obturator dislocation of the femoral head or pelvic dislocation.

Conventional versus helical blade screw insertion following the removal of the femoral head screw: A biomechanical evaluation using trochanteric gamma 3 locking nail versus PFN antirotation

tailieu.vn

In particular, the rota- tional strength compared to that of the original H de- creased by <. accompanied by femoral head bone loss experienced during the removal of the previously inserted screws [16]. [10] suggested a treatment strategy for osteosynthesis in cases of minimal femoral head bone loss with a sufficient neck–shaft angle, where a 95°-an- gled blade plate is considered if there were no defects in the inferior part of the femoral head.

Surgical correction for adult spinal deformity increases acetabular lateral coverage of femoral heads

tailieu.vn

However, it is expected that preoperatively increased PT will decrease postoperatively and its resultant increase of anterior and lateral acetabular coverage on femoral head may provide better anterior and lateral stability on hip joint.. The authors declare no personal competing interests in any of the materials, or devices described in this article. The effect of pelvic tilt on radiographic markers of acetabular coverage.

Comparison of the clinical efcacy of a femoral neck system versus cannulated screws in the treatment of femoral neck fracture in young adults

tailieu.vn

Closed reduc- tion and internal fixation can mitigate the disruption of blood supply to the femoral head, and is the preferred treatment for younger adults with femoral neck fracture;. however, none can completely prevent the occurrence of complications such as nonunion of frac- ture, femoral neck shortening, and necrosis of the femo- ral head..

Which experimental procedures influence the apparent proximal femoral stiffness? A parametric study

tailieu.vn

Collected raw data was comprised of: axial and shear loads as well as moments at the load introduction site, femoral head support force in side-fall load cases, vertical displacement of the machine head, and marker displace- ments at the five locations of : loading plate, femoral head, major trochanter, shaft, holder block. The support load, shear loads, and moments were used to check the boundary conditions of the setup.

Modified F configuration in the treatment of Pauwels type III femoral neck fracture: A finite element analysis

tailieu.vn

It may also damage the blood sup- ply of the femoral head, especially the lower retinaculum artery, which is considered to play an important role in the blood supply of the femoral head after a FNF [30].. Therefore, the model of the medial femoral neck plate was not used in this study..

Cemented hemiarthroplasty versus proximal femoral nail antirotation in the management of intertrochanteric femoral fractures in the elderly: A case control study

tailieu.vn

This prevents PFNA from transferring torque from the femoral head and neck to the cortical bone of the femoral shaft. We excluded patients with cognitive impairment, hemiplegia, and an inability to walk before their trauma, which may have caused a selection bias in the results. Hence, the number of patients in the HA group who met the inclusion criteria may be small, and the follow-up period may be shorter.

Medial patellofemoral ligament reconstruction combined with biplanar supracondylar femoral derotation osteotomy in recurrent patellar dislocation with increased femoral internal torsion and genu valgum: A retrospective pilot study

tailieu.vn

The mLDFA was measured on the full-leg standing AP radiograph and was defines as a lateral angle between a line connecting the center of the femoral head to the center of the knee and a line tangent to distal femoral condylar.

Mid-Term outcomes following fresh-frozen humeral head osteochondral allograft reconstruction for reverse Hill Sachs lesion: A case series

Gerber et al. [4] investigated twenty-one consecutive patients at a minimum of 10 years after humeral head re- construction with femoral head osteochondral allografts or iliac crest autografts.

The influence of pelvic tilt on stress distribution in the acetabulum: Finite element analysis

tailieu.vn

Recently, pelvic retroversion was reported to result in decreased acetabular cover of the femoral head [16]. In patients with osteoarthritis of the hip, pelvic anteversion is thought to increase the rate of femoral head cover and decrease the load on the acetabulum. Moreover, pelvic retroversion with lumber degenerative kyphosis results in decreased acetabular cover of the femoral head and. increased load on the acetabulum [5].

Open MRI validation of a hip model driven with subject-specific motion capture data in predicting anterior femoroacetabular clearance

tailieu.vn

The femur coordinate system was defined using medial and lateral femoral epicondyles and the center of the best fit sphere to the femoral head surface.

The accuracy of digital templating in cementless total hip arthroplasty in dysplastic hips

The placement of the COR dif- fers little from that in earlier studies, which found an average femoral head placement of 27.7–30.4 mm horizontally and 21.2–23.7 mm vertically . In patients with Crowe type III and IV and Hartofilakidis type B and C hips, the subluxation of the femoral head leads to deficient acetabular bone stock and difficulties in ace- tabular component fixation.
