The incidence of DDH Varies depending on genetic and ethnic varieties but in Ireland on an average in 3 per 1,000 live births. Current treatment is focused on early diagnosis and congruent reduction of the hip joint. With conservative measures, principally skilful use of the Pavlik harness, the majority of (85%) of dislocated or subluxated hips will be successfully treated. Late diagnosis impacts on the mode of treatment and on the subsequent outcome. An audit of annual incidence of DDH in North Eastern health board, in Ireland showed a dramatic increase in late diagnosis (>
4 month). There were 4668 live births in 2004 with 17 cases of DDH presenting between the ages of 4 – 36 months during this period. The mean age of presentation was 10 months. Two cases were bilateral. The male: female ratio was 4.6:1. Risk factor analysis showed, only 50% fell in to the high risk group, majority of them had positive family history. Three fourth of them were frank dislocations and all of them required operative intervention. As opposed to early presenters, only 10% needed operative intervention. 30% of the late presenters needed major osteotomies. We examined the reasons for this extreme high rate of late presenters and argue for the introduction of routine ultrasound screening in this region based on historical high incidence of DDH and the dramatic incidence of delayed diagnosis.
The unit was closed for 9 weeks following the outbreak and deep cleaning resulted in eradication of endemicity.
This approach enabled the surgeon to correct the deformity in all planes simultaneously, with a clearer visualization of the anatomical structures. Emphasis was placed on correcting the foot position to neutral and in particular avoiding over-correction. The corrected foot position was maintained by inserting three pins at the time of surgery, which were removed 6 weeks later. Serial casts were used for a period of 16 weeks. Tarso-pronator boots were used to maintain correction in the ambulant child.
