Slipped upper femoral epiphysis (SUFE) is the
most common hip disorder to affect adolescents. Controversy exists over
the optimal treatment of severe slips, with a continuing debate
between in situ fixation versus corrective surgery.
We present our experience in a series of 57 patients presenting
with severe unilateral SUFE (defined >
50°) managed with a subcapital
cuneiform osteotomy. Between 2001 and 2011, 57 patients (35 male, 22 female) with
a mean age of 13.1 years (9.6 to 20.3, SD 2.3) were referred to
our tertiary referral institution with a severe slip. The affected
limb was rested in slings and springs before corrective surgery
which was performed via an anterior Smith-Petersen approach. Radiographic
analysis confirmed an improvement in mean head–shaft slip angle
from 53.8. o. (standard deviation (. sd) 3.2). pre-operatively
to 9.1. o. (. sd. 3.1) post-operatively, with minimal
associated femoral neck shortening. In total 50 (88%) patients were complication
free at a mean follow-up of seven years (2.8 to 13.9 years, . sd. 3).
Their mean
Controversy remains whether the contralateral
hip should be fixed in patients presenting with unilateral slipped capital
femoral epiphysis (SCFE). This retrospective study compares the
outcomes and cost of those patients who had prophylactic fixation
with those who did not. Between January 2000 and December 2010 a total of 50 patients
underwent unilateral fixation and 36 had prophylactic fixation of
the contralateral hip. There were 54 males and 32 females with a
mean age of 12.3 years (9 to 16). The rate of a subsequent slip
without prophylactic fixation was 46%. The risk of complications
was greater, the generic health measures (Short Form-12 physical
(p <
0.001) and mental (p = 0.004) summary scores) were worse.
Radiographic cam lesions in patients presenting with unilateral
SCFE were only seen in patients who did not have prophylactic fixation.
Furthermore, prophylactic fixation of the contralateral hip was
found to be a cost-effective procedure, with a cost per quality
adjusted life year gained of £1431 at the time of last follow-up. Prophylactic fixation of the contralateral hip is a cost-effective
operation that limits the morbidity from the complications of a
further slip, and the diminished functional outcome associated with
unilateral fixation. Cite this article:
