The management of developmental dysplasia of the hip (DDH) requiring open reduction between 12 and 18 months of age is controversial. We compare the outcome of medial approach open reduction (MAOR) versus delayed anterior open reduction with Salter osteotomy in such patients.

17 consecutive patients who underwent MAOR aged 12–20 months were reviewed (mean follow-up of 40 months, range 6–74). This group was compared to 15 controls who underwent anterior reduction and Salter osteotomy aged 18–23 months (mean follow-up of 44 months, range 14–134).

13 of the 17 (76%) MAOR patients required subsequent Salter osteotomy at a mean of 22 months post-reduction, with a further 2 patients under follow-up being likely to require one. Acetabular index improved from 42 (32–50, SD − 5.5) to 16 (7–24, SD − 4.5) in the MOAR group after Salter osteotomy compared to an improvement of 40 (30–53, SD − 6) to 13 (4–24, SD − 5) in the control group (p>0.05). Acetabular index at last follow-up was within normal limits in 15 of 17 (88%) MAOR patients. All patients in the control group had acetabular indices (or centre-edge angles of Wiberg) within the normal range.

There was 1 subluxation (7%) in the control group. There were 6 cases (33%) of post-operative avascular necrosis (5 Kalamchi & MacEwen Grade I, 1 Grade 2) in the MAOR group and 6 (40%) in the control group (5 Grade 1, 1 Grade 4).

All of the MAOR patients had good or excellent clinical results according to McKay's criteria, compared to 14 out of 15 (93%) controls.

This study suggests that MAOR or delayed open reduction and Salter osteotomy is a reasonable treatment for children with DDH presenting between the ages of 12 and 18 months. However, the majority of MAORs are likely to require a subsequent Salter osteotomy.

Purpose of study

The management of developmental hip dysplasia requiring open reduction between 12 and 18 months of age is controversial. We compare the outcome of medial approach open reduction (MAOR) versus anterior open reduction with Salter osteotomy (delayed until the child is of sufficient size) in such patients.

Statement of purpose of study: To determine how effective Flexible Intramedullary Nails are in treating tibial and femoral fractures in adolescents.

Introduction Flexible intramedullary nails (FIN) are increasingly used in the management of paediatric tibial and femoral fractures. Recently, concerns have been raised regarding the use of FIN in older children. The aim of this study was to determine how effective FIN's are in treating tibial and femoral fractures in adolescents.

Methods Hospital records were used to identify all patients aged 11 years or older under going FIN for tibial and femoral fractures between 2003 and 2009. Radiographs and case notes were reviewed to identify complications.

Results 35 consecutive adolescent patients underwent FIN for tibial (n=21) and femoral fractures (n=15) with a mean age of 12.9 years. 2 femoral and 9 tibial fractures were open. Eight patients sustained multiple injuries. Mean radiographic follow up was 29 weeks. 60% (n=9) and 38% (n=9) of femoral and tibial fractures respectively malunited. Fracture severity was associated with increased malunion for both tibial and femoral fractures (P=0.046 and P=0.044 respectively). There were no cases of non-union. 2 femoral fractures took longer than 20 weeks to unite and 7 tibial fractures took longer than 16 weeks to unite. One patient developed post operative compartment syndrome, one patient developed deep infection and two patients were treated with post operative traction for loss of fracture position.

Discussion Previous publications from multiple centres, including ours, have demonstrated excellent results of FIN for tibial and femoral fractures in the general paediatric population. However, concerns have recently been raised about the use of FIN in older, heavier children and with unstable fracture patterns. This is the first published series of adolescent patients undergoing FIN. We conclude that the higher than expected rates of malunion and delayed union suggest that other treatments should be considered when treating adolescents with unstable tibial or femoral fractures.

Introduction: The management of deformities of the lower extremity in children with spina bifida is challenging. Surgery is fraught with high complication and recurrence rates. The Ilizarov technique has shown to be a successful tool in the management of complex lower limb deformity. There are few published series in the literature dealing specifically with Ilizarov correction of complex lower limb deformities in spina bifida. In this paper we present our experience of the Ilizarov technique for complex deformities in children with spina bifida.

Methods: From 1989 to 2006, 33 patients with spina bifida underwent 48 corrections of their lower extremity deformity using the Ilizarov technique at one of three tertiary care centres (Royal Children’s Hospital, Melbourne, Australia, Musgrave Park Hospital, Belfast, Northern Ireland and Birmingham Children’s Hospital, Birmingham, UK). Notes were reviewed retrospectively. Patient demographics, indications for surgery, deformity analysis and the extent of surgery were recorded. Complications of the surgery and outcomes were noted.

Results: Group I comprised of 12 fixed knee flexion deformities and one unstable neuropathic joint. Group II comprised 15 external tibial rotational deformities. Group III comprised 20 complex foot deformities. The mean age of the patients was 12.1 years (5.2–20.6 years). Prior to their treatment using the Ilizarov technique patients had undergone a mean of 1.6 previous surgeries (range: 0–5) on the affected limb. The mean duration of treatment in the frame was 9.3 weeks (range: 2–26 weeks). The mean follow-up is 4.0 years (range 0.3–9.0 years). Thirteen problems occurred in the 48 procedures (27.1%). Five obstacles occurred in the 48 procedures (10.4%). Thirteen complications occurred in the 48 procedures (27.1%). Further surgical procedures are either planned, or have been performed, in 8 of the 33 patients (24.2%). Following treatment, all feet were recorded to be plantigrade. All were comfortable in their respective orthoses where appropriate.

Conclusion: Through the pitfalls in treating the complex lower limb deformity in spina bifida, the Ilizarov technique offers a refreshing approach. It offers distinct advantages throughout the treatment period. It modifies both the intraoperative and postoperative environment to address the morbidity of the significant complications associated with the traditional approach to the correction of the limb deformity in the child with spina bifida.

Significance: This is a large series of complex limb reconstruction cases in spina bifida showing excellent results, an acceptable complication rate and recommendations for further use of this technique.

Salter’s innominate osteotomy predisposes the hip to acetabular retroversion as it hinges upon the symphysis pubis. Retroversion is a recognised cause of osteoarthritis, hip pain and clinical signs of impingement, but there is uncertainty as to whether this over cover persists with growth and development.

We reviewed the long-term follow up of twenty patients that had undergone a Salter’s osteotomy between 1985 to 1993 at The Royal Orthopaedic Hospital Birmingham or New Cross Hospital Wolverhampton. Sixteen skeletally mature patients were available for review that had previously had the pelvic osteotomy performed at a mean five years of age with a contralateral normal hip. Salter’s osteotomy had been performed for developmental dysplasia of the hip in 13 patients and for Perthes’ disease in three patients. Follow up was performed at an average age of 20 years. Outcome was assessed using the Harris Hip Score and a clinical examination for signs of impingement and by a measurement of acetabular version, on well centered pelvic radiograph.

Acetabular version was evaluated by the relationship between anterior and posterior walls of both the normal and Salter acetabulum, using radiographic templates as described by Hefti. Mean acetabular version averaged 16.9 degrees (95% CI 7.6 to 26.1) of anteversion on the Salter side and 17.6 degrees (95% CI 10.4 to 24.8) anteversion on the contralateral normal hip. There was no statistical difference between the version on operated and normal hips, paired t test (p = 0.83). Harris Hip Score averaged 85, indicating a good outcome at long-term follow up. Two patients (12%) demonstrated retroversion, however neither of these had signs of impingement on clinical examination.

After a Salter innominate osteotomy in childhood, we believe there is remodelling of acetabular version by skeletal maturity.

Aim: To audit the impact of emergency hip ultrasound in the management of suspected hip septic arthritis.

Methods and Results: Case series – Review of 13 consecutive patients who presented with acute hip pain, where clinical examination and inflammatory markers, highly suspicious of Septic arthritis.

Emergency ultrasound was only available in 9 patients.

Septic arthritis group.

– Emergency ultrasound unavailable in 2 patents. They proceeded straight to arthrotomy yielding pus.

“Non Septic Arthritis of Hip” (8 patients).

– In 2 patients emergency ultrasound unavailable. They underwent emergency arthrotomy with negative findings of pus.

If ultrasound was available in all cases, then 8 (63%) patients would have avoided an unnecessary arthrotomy.

Out of hours urgent hip ultrasound may be difficult to request. However our recent experience leads us to propose that if available ultrasound should be performed in all suspected case of hip septic arthritis prior to surgical drainage.

Pathology in the vicinity of the hip can often masquerade convincingly as a septic hip joint.

Aim: Septic Arthrits & osteomylelitis has traditionally been managed by intravenous antibiotics for 4 to 6 weeks. This requires a prolonged in patient stay, inconvience to parents, morbidity and unnecessary cost. A number of authors have suggested that shortened course of intravenous antibiotics 7–10 days are effective.

Methods: In 2001 we started to prospectively evaluate a shortened 3 day of intravenous antibiotic regime. We prospectively treated 36 cases of acute osteomyelitis and 30 cases of acute septic arthritis in children. These were confirmed by positive blood culture, positive aspirate culture, raised WCC in joint aspirate for septic arthritis or positive bone scan/culture for osteomyelitis. These patients were treated with a shortened course (3 days) of intravenous antibiotics following surgical drainage when required. Serial measurements of inflammatory markers and clinical status were recorded. On Day 4 of admission if clinical and biochemical parameters improved patients commenced high dose oral antibiotics. If no improvement they continued IV abx and consideration for repeat washout given. Patients discharged with three week course of antibiotics. Endpoint analysis of duration of IV administration, inpatient stay, readmission/reoccurrence was undertaken.

Results: 43 of the 66 (66%) patients received were discharged by Day 5 after receiving 3 full days of intravenous antibiotics. Mean in-pt stay was 5.5 days. There was one readmission for intolerance of high dose antibiotics. 6 septic patients required a repeat washout (Day 4–7 of admission). At 3 months there were no patients with ongoing infection.

Conclusion: We suggest the vast majority of acute suppurative skeletal infection can be managed safely with shortened course of intravenous and oral antibiotics following surgical drainage (in the case of intra articular infection). About 25% of patients will need longer courses of antibiotics and possibly repeat washout. This subgroup can be identified by careful clinical evaluation and measurement of inflammatory markers.

We present a review of 195 patients attending hip ultrasound clinic from June 2005–2006 to assess for hip dysplasia. 51 dysplastic hips were identified and if appropriate were treated with a Pavlik harness. Follow up was continued until ultrasound was normal. However three cases (7%) were found to be dysplastic on further follow up. Whilst this study does not prove the existence of ‘late’ dysplasia occurring in hips that were normal at birth, it does show that hips treated to normality in the first six months of life can develop recurrent dysplasia. It suggests that weaning from Pavlik harness maybe appropriate and highlights the need for long term follow up for dysplastic hips with pelvic x-ray at 5 months.

The aim of this study was to establish the consensus of opinion amongst trauma surgeons for the management of displaced supracondylar fractures of the humerus in children.

We carried out a postal questionnaire involving 130 orthopaedic surgeons with an interest in paediatric trauma. They were identified as being members of the British Society for Children’s Orthopaedic Surgery.

We received a response rate of 65%. One third of respondents believe that in uncomplicated fractures, reduction should occur within 6 hours of injury and one half felt that ‘pulseless’ fractures should be treated in the same time frame. 60% said they would explore a pulseless arm after midnight, but only 20% would reduce and stabilise uncomplicated fractures. 82% of surgeons stabilise displaced grade III fractures with K wires, of these, the majority would use a‘crossed’ configuration. If after stabilisation the arm remained pulseless, only 16% said they would explore the brachial artery immediately, 23.5% would seek a vascular opinion and 60.5% of surgeons would observe for 24 hours. If the arm remained pulseless but pink after 24 hours, the majority of surgeons would continue to observe and rely on collateral circulation for distal perfusion.

The majority of surgeons would stabilise displaced supracondylar fractures as soon as possible but not after midnight unless the arm was pulseless. If the hand remained pink but pulseless, most felt that continued observation beyond 24 hours was acceptable.

We compare the management and outcome of two management stratergies for the perfused but pulseless hand following stabilisation of grade III supracondylar fractures in children.

For this study we looked at 15 patients treated in two centres (all treated by the senior author) between 1995 and 2004. The patients were designated to group I if the pulseless hand had been observed or group II if they underwent immediate exploration. Data collected included time to surgery, neurological deficit, time to return of pulse and subsequent symptoms of forearm claudication. All patients were seen at week 1,3 and followed for at least 6 months post surgery. Radiographs were reviewed to determine the adequacy of reduction of the fracture.

The mean age of patient was 3.8 years. Median time to surgery was 6 hours. 6 children had evidence of anterior interosseus nerve palsy. 12 cases were reduced anatomically, 3 had minimal fracture gap. Of the 8 patients in group I (observation) 2 had secondary exploration and one developed claudication symptoms. All had palpable radial pulse at 3 months.6 of the 7 patients in group II (exploration) were seen to have brachial artery tethering, 2 with median nerve entrapment. 5 of them had subsequent return of radial pulse within 24 hours.

Satisfactory radiological reductionof the fracture does-not exclude vessel or nerve entrapment. We would advocate early exploration of the artery if the pulse does not return within 24 hours.

The aim of this study was to assess the usefulness of Cast index and an indigenously developed Gap index as measures of poor moulding of plaster. 20 cases of re-manipulation of distal third forearm fractures excluding growth plate injuries were compared with a control of 80 patients. 5 patients in the control group had an axial deviation of more than 10 degrees but were not remanipulated and therefore were included in the failure group. The gap index and the cast index of the two groups was compared as predictors of failure of conservative treatment. The groups were similar in terms of demography and post reduction alignment. There was a significant difference (< 0.001) in the Cast index and the Gap index of both the groups. The sensitivity of the Cast index (> 0.8) in predicting failure of plaster was 48% while that of the sum of Gap index (> 0.15) in AP & Lat view was 88%. Gap index was found to be more accurate (84%) than Cast index (78%) in predicting failure. The gap index is a better predictor of failure than the cast index. A quick assessment of these indices, especially by the less experienced surgeons, is a good practice before accepting any plaster following a manipulation of distal radial fractures. It would not only save the patient a second anaesthesia but also complications of a more extensive second procedure and of course hospital resources.
