Background:

Displaced femoral neck fracture (FNF) is a common injury in the

elderly, and treatment with total hip arthroplasty (THA) has low complication

and revision rate. Less is known about the functional results after ended reha-

bilitation.

Purpose / Aim of Study:

To investigate function, health status and satisfac-

tion in patients treated with primary THA after displaced FNF.

Materials and Methods:

From 2005-2011, 414 consecutive FNF patients

were operated with Saturne Dual mobility (DM) THA. At min 1-year follow-up,

124 (95 women) responded to an invitation and were evaluated with Oxford

Hip Score (OHS), a general health-related quality of life measure (EQ-5D) and

2 functional tests: Timed Up and Go (TUG) and Sit To Stand 10 times (STS).

The FNF patients were matched 1:2 by age, sex and surgery date with patients

receiving THA due to osteoarthrosis (OA group) with 1 year OHS and EQ5D.

EQ-5D for the FNF group was matched to the general population index.

Findings / Results:

Patient age at time of surgery was mean 74.8 (range 30-

92) years. At a mean follow-up of 2.8 (1.0 – 7.7) years the mean EQ-5D score

was 0.79 (sd 0.15) in the FNF group, which was similar to the matched gen-

eral populations index (p=0.4), but lower (p=0.001) when compared to the

OA group. Mean OHS was 36.4 (sd 9.5) in the FNF group and 38.4 (sd 7.2) in

the OA group (p=0.05). Hip pain (Q1 from OHS) was similar between groups

(p=0.10). Mean TUG was 13.5 (sd 4.9) sec and mean STS was 37.9 (sd 15.3)

sec in the FNF group. Mean VAS at rest was 1.0 (sd 1.7) and during activity 2.1

(sd 2.7), and 89% were satisfied with the result of the operation in the FNF

group.

Conclusions:

At short term follow-up, patients with DM THA following dis-

placed FNF had a good functional and satisfaction result. EQ-5D was similar to

the age/gender matched population index, but lower compared with OA THA

patients.
