This study analysed the clinical and radiological outcome of
anatomical reduction of a moderate or severe stable slipped capital
femoral epiphysis (SCFE) treated by subcapital osteotomy (a modified
Dunn osteotomy) through the surgical approach described by Ganz. We prospectively studied 31 patients (32 hips; 16 females and
five males; mean age 14.3 years) with SCFE. On the Southwick classification,
ten were of moderate severity (head-shaft angle >
30° to 60°) and
22 were severe (head-shaft angle >
60°). Each underwent open reduction
and internal fixation using an intracapsular osteotomy through the
physeal growth plate after safe surgical hip dislocation. Unlike
the conventional procedure, 25 hips did not need an osteotomy of
the apophysis of the great trochanter and were managed using an
extended retinacular posterior flap. Aims
Patients and Methods
Proximal femoral resection (PFR) is a proven
pain-relieving procedure for the management of patients with severe cerebral
palsy and a painful displaced hip. Previous authors have recommended
post-operative traction or immobilisation to prevent a recurrence
of pain due to proximal migration of the femoral stump. We present
a series of 79 PFRs in 63 patients, age 14.7 years (10 to 26; 35
male, 28 female), none of whom had post-operative traction or immobilisation. A total of 71 hips (89.6%) were reported to be pain free or to
have mild pain following surgery. Four children underwent further
resection for persistent pain; of these, three had successful resolution
of pain and one had no benefit. A total of 16 hips (20.2%) showed
radiographic evidence of heterotopic ossification, all of which
had formed within one year of surgery. Four patients had a wound
infection, one of which needed debridement; all recovered fully.
A total of 59 patients (94%) reported improvements in seating and
hygiene. The results are as good as or better than the historical results
of using traction or immobilisation. We recommend that following
PFR, children can be managed without traction or immobilisation,
and can be discharged earlier and with fewer complications. However,
care should be taken with severely dystonic patients, in whom more
extensive femoral resection should be considered in combination
with management of the increased tone. Cite this article:
