Summary of "Radiographic Predictors of Screw Cutout for Intertrochanteric Fractures Treated With Cephalomedullary Nails."

The objective of this study was to determine the predictive value of tip-apex distance (TAD) and Parker's ratio for screw cutout after treatment of intertrochanteric hip fractures with a long cephalomedullary nail. A total of 97 patients with AO/OTA 31-A1-A3 intertrochanteric fractures and a minimum follow-up of 8 weeks were included. Increased Parker's ratio on the anteroposterior radiograph (OR = 1.386, p < .003) and lateral radiograph (OR = 1.138, p < .028) was significantly associated with screw cutout. In a multivariable regression analysis, only the Parker's anteroposterior ratio was significantly associated with risk of screw cutout (OR = 1.393, p = .004), but TAD (OR = 0.977, p = .764) and Parker's lateral ratio (OR 1.032, p = .710) were not independent predictors of cutout. The study concluded that Parker's anteroposterior ratio is the most helpful measurement in predicting screw cutout. (Journal of Surgical Orthopaedic Advances 28(2):115-120, 2019).

Medical and Biotech [MESH] Definitions

Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters. It excludes intertrochanteric fractures which are HIP FRACTURES.

Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

Fractures of the FEMUR HEAD; the FEMUR NECK; (FEMORAL NECK FRACTURES); the trochanters; or the inter- or subtrochanteric region. Excludes fractures of the acetabulum and fractures of the femoral shaft below the subtrochanteric region (FEMORAL FRACTURES).

Use of optic and geometric techniques to enhance radiographic image quality and interpretation. It includes use of microfocal X-ray tubes and intensifying fluoroscopic screens.

Computer systems or networks designed to provide radiographic interpretive information.
