The femoral neck-shaft angle on plain radiographs: a systematic review

Skeletal Radiology, 2015
The femoral neck-shaft angle (NSA) is an important measure for the assessment of the anatomy of the hip and planning of operations. Despite its common use, there remains disagreement concerning the method of measurement and the correction of hip rotation and femoral version of the projected NSA on conventional radiographs.

Lateralization and Decreased Neck-Shaft Angle Reduces Scapular Notching and Heterotopic Ossification

Journal of the American Academy of Orthopaedic Surgeons, 2020
Background: Lateralization of the glenosphere in reverse shoulder arthroplasty likely mitigates scapular notching; however, there is a paucity of data evaluating the effect of heterotopic ossification (HO) at the inferior aspect of the glenoid neck.

An approach for fully automatic femoral neck-shaft angle evaluation on radiographs

Review of Scientific Instruments, 2020
Femoral neck-shaft angle (NSA) is the angle included by the femoral neck axis (FNA) and the femoral shaft axis (FSA), which is a critical anatomic measurement index for evaluating the biomechanics of the hip joint. Aiming at solving the problem that the physician’s manual measurement of the NSA is time consuming and irreproducible, this paper proposes ...

PH5 Shaft/neck angle of the femur/age [radiography]

1991
As with femoral anteversion, many measurement methods have been proposed to define the femoral shaft/neck angle. Several of these do not take into consideration the anteversion, measure directly on the AP film, and give a considerable error. In one method which combines fluoroscopy and radiography the leg is rotated to a true AP of the plane through ...

The neck shaft-plate shaft angle in slipped capital femoral epiphysis.

Orthopaedic review, 1989
We looked for structural differences between normal patients and those with slipped capital femoral epiphysis to explain shear failure of the growth plate in terms of mechanics. Hip radiographs of 50 normal adolescents were examined, and it was found that lines drawn along the axis of the femoral neck and perpendicular to the growth plate intersected ...

Measurements of Femoral Neck‐Shaft Angle in the Growing Beagle

Veterinary Surgery, 1980
The angles of inclination and anteversion were measured radiographically in 8 beagles, at 4‐week intervals from 14 to 38 weeks of age, the time of radiographic physeal closure. Minimal changes in the femoral neck‐shaft angles were observed during this observation period. The results indicate that surgical correction of altered femoral neck‐shaft angles

Femoral Anteversion and Neck-Shaft Angles in Hip Instability in Cerebral Palsy

Journal of Pediatric Orthopaedics, 1994
A consecutive sample of 411 hip roentgenograms in 215 patients with cerebral palsy was evaluated. Femoral anteversion and neck-shaft angles were measured and compared with hip stability indexes to determine which of the two angles is more important in hip instability.

The Effect of Femoral Rotation on the Projected Femoral Neck-Shaft Angle

Journal of Pediatric Orthopaedics, 2000
Femoral neck-shaft angle (NSA) was measured in a series of anteroposterior (AP) hip radiographs of a cadaveric femur in varying degrees of rotation. A mathematical model was developed to predict NSA on an AP radiograph in varying degrees of femoral rotation.

A new method of measuring the femoral anteversion and neck-shaft angles

Clinical Radiology, 1984
A new and simple method for measuring the femoral anteversion and neck-shaft angles, based on descriptive geometric principles, is described. Its technique and geometrical analysis are also analysed. The results have proved to be very accurate. Graphs have been prepared from which one can readily determine the anteversion and neck-shaft angles, once ...

Femoral torsion and neck-shaft angles in cerebral palsy.

Journal of pediatric orthopedics, 1993
Excessive femoral and coxa valga have been reported to be major contributors leading to hip dislocation in patients with cerebral palsy (CP). Femoral torsion angle (FT) and neck-shaft angle (NSA) were measured by the radiographic technique described by Rippstein and Müller in 157 patients with CP (289 hips). Factors associated with the degree of FT and
