The Effect of Fracture Pattern Stability on Implant Loading in OTA Type 31-A2 Proximal Femur Fractures

Abstract

Type 31-A2 fractures become increasingly unstable with increased medial comminution (or fragment size). SHS-P constructs were more load sharing than SHS-IMN constructs. These findings may help guide the surgeon in choice of implant for a 31-A2 intertrochanteric fracture, leaning toward SHS-IMN for the more unstable fracture patterns.

Trochanter stabilising plate improves treatment outcomes in AO/OTA 31-A2 intertrochanteric fractures with critical thin femoral lateral walls

“…The clinical records including age, gender, injured side, subtypes of A2 fractures [1], the extent of lesser trochanter comminution [11], classification of American Society of Anesthesiologists (ASA), and lateral wall thickness [4] were collected and used in the standard univariate and multivariate analyses. The study flow chart is shown in Fig.…”

Plating Intertrochanteric Hip Fractures

“…1). 1,11,12,17,18 Selection of proximal femoral plating over CMN in managing fracture patterns amenable to both fixation techniques is largely related to surgeon preference. 2,3 Meta-analysis of the present literature shows no significant differences in clinical outcomes to support CMN over SHS.…”

“…In the process of deciding the mode of effective internal fixation, it is imperative to recognize distinct fracture features as well as consider patient bone quality for suitable implant selection and technique. 1 Definitive evidence for utilizing one implant over another is not entirely clear in the literature and recent surgeon trends have inclined toward utilizing CMNs for management. 2,3 However, proximal femoral plating remains a proven and effective option for certain intertrochanteric hip fracture types.…”

Experimental and Theoretical Validation of Double Column Internal Fixation Theory for Distal Femoral Fractures

“…В работе M. Marmor с соавторами, посвящен-ной остеосинтезу переломов проксимального отдела бедренной кости, также сделан вывод о том, что утрата медиальной опоры увеличива-ет нестабильность перелома, а имплантаты, обе-спечивающие медиальную поддержку, предпо-чтительнее в использовании при остеосинтезе переломов этой локализации [29]. В 2016 г. N. Briffa с соавторами опубликова-ли результаты биомеханического сравнитель-ного анализа стабильности пластин при осевой нагрузке, расположенных по медиальной и ла-теральной поверхностям дистального отдела бед ренной кости.…”
