Abstract
The advantage of the Evans, OA / ASIF and OTA classifications,
compared to other classification systems, is to distinguish between #pertrochanteric and #intertrochanteric fractures. These are characterized
by their epidemiological peculiarities, difficult reductions and by
their rather high complication rates. The aim of the authors is to
review the difficulties and complications encountered in a study of 14
cases in order to distinguish this entity, which is frequently
considered to be a pertrochanteric fracture. Most studies evaluate all trochanteric fractures together as a single
group (i.e., 31A1, 31A2 and 31A3 according to the AO classification).
However, intertrochanteric fractures (31A3) constitute a different
group, both in terms of #biomechanics and anatomy. In pertrochanteric
fractures (31A1 and 31A2), the main criterion of distinction is the
fracture stability (Figure 1). This study emphasizes the importance of
distinguishing between intertrochanteric fractures and other
trochanteric fractures, which are difficult wounds and accompanied by a
high rate of complications and require surgical treatment with gamma
nail or better long-term gamma nail. AO, and DHS should only be used in
exceptional cases (47-54). The aim of this study is to evaluate the clinical and radiological
results of intertrochanteric fractures (31A3) treated with conventional
gamma nails. The prospective study focused on 14 patients with closed
intertrochanteric fractures classified as AO 31A3 in the
#Traumatology-Orthopedics department of the Moulay Ismail Military
Hospital in Meknes over a period of 5 years, between January 2012 and
November 2016. The methods of study were based on the exploitation of
medical records.
