TI  - Early and mid-term results of Tönnis lateral acetabuloplasty
for the treatment of developmental dysplasia of the hip
AB  - Objectives: This study aimed to present the clinical and
radiological results of a large patient group operated by Tönnis
lateral acetabuloplasty (TLA) for developmental dysplasia of the
hip (DDH).
Patients and methods: The retrospective study was conducted
with 66 hips of 41 patients (5 males, 36 females; mean age:
32.3±18 months; range, 11 to 132 months) operated for DDH
using the TLA technique in a single center between February
2012 and December 2016. Adductor tenotomy was performed
on 52 (79%) hips. There was a need for additional femoral
shortening and derotation-varization osteotomy in 14 (21%)
hips. Clinical outcomes were evaluated with modified McKay
criteria. The acetabular index and lateral migration index for the
subluxated hip were calculated, and the femoral head position
was evaluated according to Perkin’s line and Shenton’s line. The
Severin classification was used to assess the outcome of the hips.
Results: The mean follow-up period was 27±11 months.
According to the modified McKay criteria for DDH, 77.3% of
hips were classified as excellent, 16.6% as good, and 6.1% as fair.
The mean acetabular index decreased from 36.1° preoperatively
to 18.6° postoperatively. The mean postoperative improvement
for the acetabular index was 17.5±5. The lateral migration index
improved from 89.7 to 10.6%. A statistically significant difference
was determined between the preoperative and postoperative
measurements of the acetabular index and lateral migration index
(p<0.001).
Conclusion: Tönnis lateral acetabuloplasty was found to be safe
and effective with a low learning curve, and successful treatment
decreases the duration of follow-up required in patients with
DDH.
