Background:

50 % of elderly patients admitted with a hip fracture have a

pertrochanteric fracture and are often treated with an intramedullary nail. In

Denmark we have no consensus among orthopaedics in the choice of intramed-

ullary nails.

Purpose / Aim of Study:

To examine the incidence of reoperation and differ-

ence in failures for short gamma nail (SGN) and long gamma nail (LGN)

Materials and Methods:

Patients with a pertrochanteric fracture treated with

a Gamma 3 nail in 5 different hospitals in Southern Denmark in 2012 were

included. Data was received from Dansk Tværfagligt register for hoftenære

Lårbensbrud. All patients included were treated with either SGN or LGN. For all

patients we received CPR, operation date, diagnose and if relevant reoperation

date and treatment. All radiographs were examined to divide the patients into

the two groups SGN and LGN and to classify the fracture. TAD and diathesis

were measured on post operative x-rays. If the patient were reoperated the

failure and the choice of treatment were found in the medical journal with 2

years follow up.

Findings / Results:

216 out of 250 fractures were included. Patients excluded

did not have a pertrochanteric fracture, another treatment then Gamma 3 nail,

another treatment or x-ray was not available. We found 12 reoperations, 5 and

7 in the SGN and LGN group. 3 cut out in each group. 1 patient with LGN sus-

tained ipsilateral fracture after a second fall, but no patients with SGN had a

secondary fracture. 1 patient with SGN had a hairline fracture seen on the post

operative x-ray. 1 patient in each group had a total hip arthroplasty because

of arthrosis. 1 with LGN had a non union and 1 with LGN had the nail removed

because of pain.

Conclusions:

There is no difference between SGN and LGN in the type of fail-

ures or the incidence of reoperations.

No conflicts of interest reported
