Abstract
Slipped capital femoral epiphysis (SCFE) is an adolescent hip
disorder with displacement of the capital femoral epiphysis from the
metaphysis through the physis.
Once SCFE is diagnosed, surgical treatment is indicated, but
significant controversies remain regarding the best treatment. Moderate to
severe SCFE results in femoroacetabular impingement that leads to
premature osteoarthritis.
Modified Dunn procedure provides capital realignment through a
surgical dislocation approach with less incidence of osteonecrosis and
chondrolysis.
This prospective clinical study had been performed between June
2017 to December 2018 in Menoufia University Hospitals included 20
patients (20 hips) with chronic and stable SCFE of moderate and severe
degrees. They were treated by the modified Dunn procedure using a
trochanteric osteotomy for surgical dislocation of the hip with the
development of a periosteal-retinacular soft tissue flap where the femoral
epiphysis could be mobilized safely and reduced on the femoral neck after
resection of the reactive metaphyseal callus. The minimum follow up period
was twelve months.
Summary
173
In this study, the mean period of follow up was 13.75± 2.59 (range,
12-20) months.
Radiologically, all parameters showed significant improvement; with
the mean slip angle was corrected from 50.75± 15.15 degrees preoperatively
to -1.70 ± 1.78 degrees. The mean alpha angle was corrected from 72.48 ±
10.11 degrees preoperatively to 40.40 ± 6.40 degrees postoperatively.
Functionally, the mean Harris hip score (HHS) was significantly
improved from a preoperative value of 45 ± 11.55 points to a postoperative
value of 91.8 ± 11.55 points. Excellent result was achieved in 85%, fair
result in 5% and poor result in 10%. Postoperative major complications
occurred in three patients (15%); AVN in two (10%) and hip dislocation in
another (5%).
