Surgery for DDH is one of the common paediatric orthopaedics procedures in a tertiary care paediatrics hospital. There are no uniformly agreed guidelines about the pre-operative work up related to blood transfusion in DDH surgery. This leads to lack of uniformity in practice, sometimes causes cancellations of operations on the day of surgery (due to no cross matched blood available) and on other occasions wastage of the cross matched blood. The aims of our study were to know the incidence of perioperative blood transfusion in a series of DDH operations and to determine what types of operations/kids have more chances of needing a blood transfusion peri-operatively. We included all children who had surgery for DDH between April 2009 and October 2012 in our institution. We found out which of these children had blood transfusion peri-operatively and reviewed their notes to determine any trends in transfusion requirements 165 children had operations for DDH during the study period. This included operations ranging from hip open reduction to Ganz osteotomy. 6 out of 165 (4%) were transfused blood. Children needing blood transfusion tended to be older and had multiple hip operations previously. Only 3 (2 during Ganz and 1 during bilateral hip reconstruction) of these 6 children needed intra-operative blood transfusion. None of the under 4 years old children needed intra-operative blood transfusion. We conclude that children for unilateral primary hip operations for DDH do not need pre operative blood cross match. A group and save is enough in these cases.
To determine (i) the relationship between osteonecrosis and hip function, physical function and quality of life in adolescents and young adults treated for DDH; and (ii) how affected children change over 10 years. We included 109 patients (mean age 19.2 ± 3.8 years) with osteonecrosis and 30 age-matched patients without osteonecrosis following DDH treatment between 1992–2005. All completed valid patient-reported outcome measures to quantify their hip function (maximum score 100); physical function (maximum score 100); and quality of life (maximum score 1). Of these, 39 patients had been followed prospectively since 2006, allowing quantification of within-person changes over time. We graded all radiographs for severity of osteonecrosis, residual dysplasia, subluxation and osteoarthritis. We determined the association between patient-reported outcomes and radiographic severity of osteonecrosis using mixed-effects regression analysis; and repeated-measures analysis of variance to quantify person changes over time. We adjusted for age, prior operations and acetabular dysplasia.Purpose

In Northern Ireland the Health Visitor assessment at 6 months was demonstrated to be successful in detecting the majority of cases of DDH and was maintained, although moved to 4 months. There has been increased numbers of referrals resulting in prolonged waiting times for low risk infants. A retrospective review was performed of the records of all children treated for DDH in the three-year birth cohort from 2008 to 2010. Data was obtained by collating the records of the nurse led clinics, inpatient records and theatre logs from the three treating centres. 584 children were treated, 87% female. Treatment rate was 7.7/1,000 live births (2003 = 5.2). Twenty-three cases were diagnosed later than 1 year of age, 0.3/1,000 (2003 = 0.6); 146 cases were diagnosed later than 6 months 1.9/1000 (2003=1.7) of these 62 required operative treatment, 0.8/1,000 (2003 =1.1). The median age at referral was 7 weeks and ranged from 0 to 119 weeks. The median delay to be seen was 29 days with a highly skewed distribution, which ranged from 0 to 39 weeks. We found if waiting times had been capped at 9 weeks, as has been the case for other orthopaedic conditions, 52 patients who were seen after 6 months would have been seen on average 140 days earlier.Methods
Results
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.
Obtaining fixation in DDH with Surface arthroplasty (SA) with a two part polyethylene (PE ) socket was technically challenging. Although dislocation was rare there was a high loosening rate secondary to polyethylene wear. The purpose of this study was to evaluate the results of Conserve Plus metal-on-metal SA in Crowe class I and II Developmental Dysplasia of the Hip patients. 54 patients (59 hips), 72% females, average age43.7 years (15 to 63.8) met these inclusion creteria with 2 years of follow-up minimum. Seven hips were Crowe type II and fifty-two were type I. Harlan C. Amstutz, John Antoniades, Michel J. Le Duff, Paul E. Beaulé The results of MMSA are much improved over those of prior generations of SA and socket fixation is stable even in Crowe type II with the porous coated acetabular components without adjuvant fixation despite incomplete acetabular coverage of the socket. The hips have-been stable even with important range of motion. Recent short term failure and radiolucencies have been eliminated by improved technique despite a high incidence of femoral cysts and reduced area of fixation.
To assess the radiological outcomes of medial screw epiphyseodesis of the proximal femoral physis in the management of lateral growth arrest following treatment of developmental dysplasia of the hip. We identified 10 patients noted to have lateral growth disturbance of the proximal femoral physis, 9 of which were managed with medial screw epiphyseodesis. Serial radiographs were reviewed. A new technique was employed to monitor progression of lateral growth arrest and also to assess the role of screw epiphyseodesis in preventing further deterioration or indeed allowing for improvement. This method involved calculating the tilt angle (angle formed between a horizontal reference line and a line joining medial and lateral points of physis) and following its progression with increasing age.Purpose of Study
Methods
Between June 1988 and December 1997, 332 babies with 546 dysplastic hips were treated in the Pavlik harness for primary Developmental Dysplasia (DDH) as a product of the Southampton selective screening program. Each was managed by a strict protocol including ultrasonic monitoring of treatment within the harness. The group was prospectively studied over a mean duration of 6. 5 years (SD=2. 7y) with 89. 1% follow-up. The Acetabular Index (AI) and Centre-Edge angle of Wiberg (CEA) were measured on annual radiographs to determine the natural history of hip development following treatment in the Pavilik harness. These were compared to published normal values. We observed a failed reduction rate of 15. 2% of all complete hip dislocations; these required alternative surgical treatment. The development of those hips of infants successfully treated in the harness showed no significant difference from the normal values of Acetabular Index for female left hips, after eighteen months of age. Of those dysplastic hips that were successfully reduced in the harness; 2. 4% exhibited persisting significant late dysplasia (CEA<
20°) and 0.2% demonstrated persistent severe late dysplasia (CEA<
15 °) All such cases could be identified at sixty months. Dysplasia was clinically deemed sufficient to merit innominate osteotomy in 0. 9% dysplastic hips treated. Avascular necrosis was noted in 1% of hips treated in the harness. We conclude that using our protocol, successful initial treatment of DDH with the Pavlik harness appears to revert the natural history of hip development to that of the normal population. We recommend that regular radiographic surveillance up to 60 months of age constitutes safe and effective practice.

The objective of this study was to present the outcomes of rotational acetabular osteotomy (RAO) over a 30-year period for osteoarthritis (OA) secondary to dysplasia of the hip in pre- or early-stage OA. Between September 1987 and December 1994, we provided treatment to 47 patients (55 hips) with RAO for the management of pre- or early-stage OA due to developmental hip dysplasia. Of those, eight patients (11 hips) with pre-OA (follow-up rate 79%) and 27 patients (32 hips) with early-stage OA (follow-up rate 78%), totalling 35 patients (43 hips) (follow-up rate 78%), were available at a minimum of 28 years after surgery.Aims
Methods
Although periacetabular osteotomies are widely used for the treatment of symptomatic dysplastic hips, long-term surgical outcomes and patient-reported outcome measures (PROMs) are still unclear. Accordingly, we assessed hip survival and PROMs at 20 years after transpositional osteotomy of the acetabulum (TOA). A total of 172 hips in 159 patients who underwent TOA were followed up at a mean of 21.02 years (16.6 to 24.6) postoperatively. Kaplan-Meier analysis was used to assess survivorship with an endpoint of total hip arthroplasty (THA). PROMs included the visual analogue scale (VAS) Satisfaction, VAS Pain, Oxford Hip Score (OHS), and Forgotten Joint Score-12 (FJS-12). Thresholds for favourable outcomes for OHS (≥ 42) and FJS-12 (≥ 51) were obtained using the receiver operating characteristic curve with VAS Satisfaction ≥ 50 and VAS Pain < 20 as anchors.Aims
Methods
The aims of this study were to compare clinically relevant measurements of hip dysplasia on radiographs taken in the supine and standing position, and to compare Hip2Norm software and Picture Archiving and Communication System (PACS)-derived digital radiological measurements. Preoperative supine and standing radiographs of 36 consecutive patients (43 hips) who underwent periacetabular osteotomy surgery were retrospectively analyzed from a single-centre, two-surgeon cohort. Anterior coverage (AC), posterior coverage (PC), lateral centre-edge angle (LCEA), acetabular inclination (AI), sharp angle (SA), pelvic tilt (PT), retroversion index (RI), femoroepiphyseal acetabular roof (FEAR) index, femoroepiphyseal horizontal angle (FEHA), leg length discrepancy (LLD), and pelvic obliquity (PO) were analyzed using both Hip2Norm software and PACS-derived measurements where applicable.Aims
Methods
Rotational acetabular osteotomy (RAO) has been reported to be effective in improving symptoms and preventing osteoarthritis (OA) progression in patients with mild to severe develomental dysplasia of the hip (DDH). However, some patients develop secondary OA even when the preoperative joint space is normal; determining who will progress to OA is difficult. We evaluated whether the preoperative cartilage condition may predict OA progression following surgery using T2 mapping MRI. We reviewed 61 hips with early-stage OA in 61 patients who underwent RAO for DDH. They underwent preoperative and five-year postoperative radiological analysis of the hip. Those with a joint space narrowing of more than 1 mm were considered to have 'OA progression'. Preoperative assessment of articular cartilage was also performed using 3T MRI with the T2 mapping technique. The region of interest was defined as the weightbearing portion of the acetabulum and femoral head.Aims

To quantify the prevalence of Generalized Joint Hypermobility (GJH), aka Hypermobility Spectrum Disorder, in adult patients presenting with hip pain to a sub-specialty hip practice, this 4-year, prospective, observational study evaluated correlations with clinical, demographic, and baseline outcomes. 1,004 consecutive new hip patients (390 males, 614 females) were evaluated for GJH using the Beighton 9-point physical exam criteria and the Hakim-Grahame 5-item history questionnaire. Diagnosis, age, sex and race were tested as predictors of GJH. Patient reported outcomes from iHOT-12 and a modified Harris Hip Score (mHHS) were also assessed. There were 333 patients presenting with hip dysplasia over this period.

Iliopsoas pathology is a relatively uncommon cause of pain following total hip arthroplasty (THA), typically presenting with symptoms of groin pain on active flexion and/or extension of the hip. A variety of conservative and surgical treatment options have been reported. In this retrospective cohort study, we report the incidence of iliopsoas pathology and treatment outcomes. Methods. A retrospective review of 1,000 patients who underwent THA over a five-year period was conducted, to determine the incidence of patients diagnosed with iliopsoas pathology. Outcome following non-surgical and surgical management was assessed. Results. In all, 24 patients were diagnosed as having developed symptomatic iliopsoas pathology giving an incidence of 2.4%. While the mean age for receiving a THA was 65 years, the mean age for developing iliopsoas pathology was 54 years (28 to 67). Younger patients and those receiving THA for conditions other than primary osteoarthritis were at a higher risk of developing this complication. Ultrasound-guided steroid injection/physiotherapy resulted in complete resolution of symptoms in 61% of cases, partial resolution in 13%, and no benefit in 26%. Eight out of 24 patients (who initially responded to injection) subsequently underwent surgical intervention including tenotomy (n = 7) and revision of the acetabular component (n = 1). Conclusion. This is the largest case series to estimate the incidence of iliopsoas pathology to date. There is a higher incidence of this condition in younger patients, possibly due to the differing surgical indications. Arthoplasty for Perthes' disease or
