Aim

To compare outcomes for children treated for idiopathic clubfeet with the Ponseti regimen before (2002–2004) and after (2005–2006) implementation of a dedicated Ponseti service.

Aim

10 years after the introduction of the Ponseti casting regimen as standard treatment for idiopathic clubfoot at Alder Hey Children's Hospital, we reviewed the mid-term outcomes of the initial 2-year cohort (treated from 2002–2004)

Purpose: Scarf osteotomies are commonly performed in adults with symptomatic bunions. We have reported the radiological and clinical outcome of this procedure in the treatment of moderate to severe hallux valgus among adolescent children.

Methods: Data was collected retrospectively from a tertiary referral children hospital between April 2001 and June 2006. The pre and postoperative intermetatarsal angle (IMA), hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA) were determined. Patients were followed up for a mean of 8.6 months (3–18).

Results: 23 scarf osteotomies were performed in 16 patients with a mean age of 14.3 years (12–18). The mean pre operative IMA of 14.4 degrees was improved to a postoperative value of 9.3 degrees, p< 0.0001. The mean HVA angle was improved from 34.7 to 16.5 degrees, p< 0.0001. The DMAA was improved from 13.1 to 8 degrees, p< 0.0001. There were 2 cases of superficial wound infections successfully treated with oral antibiotics. One patient developed a complex regional pain syndrome that resolved with physiotherapy and analgesia.

Conclusion: We believe that scarf osteotomy is a safe and effective option for the management of the adolescent symptomatic bunions.

Significance: There are no published reports in the English literature of scarf osteotomy in the management of adolescent children with symptomatic hallux valgus. The aim of this paper is to report the radiological and clinical outcome of scarf osteotomy in the treatment of moderate to severe hallux valgus among adolescent children.

Purpose of Study: To present the clinical features, investigations, histopathology, differential diagnosis and treatment options for lipoblastoma, based on a series of six encountered in our paediatric orthopaedic practice.

Method: The records of six children with lipoblastoma who attended Alder Hey Hospital between 2000 and 2006 were reviewed. Mean age was 17 months and mean follow up was 26 months.

Results: The youngest was a six month old infant with a swelling on his right instep. The second patient, a three year old girl, presented with a limp and swelling in her foot. The third patient was an 18 month old boy with a swelling on the dorsum of his left forearm. The fourth patient had a swelling of his left thigh and two patients had swellings in their backs. Each was investigated by MRI (1), CT (1) or US (4) and surgical excision planned accordingly. There were no post operative complications. None has shown recurrence during follow-up.

Conclusions: All patients were originally thought to have simple lipomata or soft tissue swellings. This is primarily because lipoblastoma is a rare tumour, yet lipoblastoma is the most likely diagnosis of a fatty lump in a child aged less than two. Differential diagnoses include myxoid liposarcoma, well-differentiated liposarcoma, spindle cell lipoma, typical lipoma and soft tissue sarcoma.

Lipoblastomata need thorough imaging. Cytogenetic evaluation of tumour cells often reveals chromosomal anomalies, such as abnormalities of the long arm of chromosome 8 leading to rearrangement of the PLAG1 gene. Biopsy of the lesion is recommended for accurate diagnosis, as clinical and radiological diagnoses can be misleading.

Lipoblastomata tend to spread locally and may recur after incomplete resection; metastatic potential has not been reported. Complete surgical resection is mandatory to prevent recurrence.

Introduction: It is common practice to screen the hips of infant with a family history of DDH clinically and ultra-sonographically in selective screening programmes. The practice of regular radiographic follow-up of infants with a positive family history of Developmental Hip Dysplasia (DDH) is based on the widespread belief that Primary Acetabular Dysplasia is a genetic disorder that can occur in the absence of frank hip subluxation or dislocation¹. It has been our practice to obtain a 6 – 12 month screening radiograph in such patients but this practice is not conclusively supported in the literature.

Materials and Methods: We reviewed all such infants who had a normal clinical and ultrasound examination of the hips at the 6–8 week screening examination but who, because of the family history underwent further radiographic screening after a 6–12 month interval. The radiographs of all such infants (n=77) were analysed for any signs of late hip dysplasia.

Results and Discussion: Sixty six infant had normal X rays at the 6–8 month assessment and were discharged. The remaining eleven patients had acetabular angles at the upper end of the normal range for age and were reviewed again with further radiographs at 12 months. At this stage ten patients were normal and were discharged. The remaining patient was reviewed again at 18 months and 24 months and finally proved to be normal and was discharged. The result of a postal survey has suggested that majority of BSCOS members do not get follow up x-ray done if the clinical and ultrasound scan is normal at screening visit.

Conclusion: All of the seventy seven patients eventually developed normal radiographs and we question the need for radiographic follow up of infants with a family history of DDH but who have a normal clinical examination and ultrasound scan at 6–8 weeks.

Aim: A retrospective study to analyse the treatment of paediatric diaphyseal forearm fractures over the preceding 6 years and to assess if there was any difference in outcome between plate and elastic stable intra-medullary nailing (ESIN).

Material and Methods: Between January 1997 and December 2002, 144 unstable fractures required surgical fixation. 59 patients were treated with both-bone plate fixation, 55 patients were treated with single-bone plate fixation and 30 patients were treated with ESIN.

The mean age of surgery was approximately 12 with peaks at age 8 and 13 years.

In the plate group, 70% to 80% were undertaken by the SpRs and in the nailing group, approximately 50% were undertaken by staff grades; 30% by Consultants and 20% by SpRs.

Results: Between each group there was no difference in time spent in plaster, clinic attendance, time to clinical union and time to restoration of normal movements. On radiographic reviews, single-bone plate fixation patients united quicker than the both-bone plate fixation or ESIN groups. Average anaesthetic times became more prolonged from single-bone to ESIN to both-bone plate fixation.

Compound fractures were approximately 10% in both groups. There were hyper-trophic scars in approximately 10% in the plate group and 3% in the nail group. There were 3 compartment syndromes in the plate group and 2 compartment syndromes in the nail group.

In the plating groups, there was a higher rate of peri-prosthetic fracture, mal-union, hyper-trophic scarring, infection and neuro-vascular complications.

Conclusion: ESIN is superior to plating in relation to surgical complications. It is therefore recommended that elastic stable intra-medullary nailing should be used for displaced paediatric diaphyseal forearm fractures.

Aim: To evaluate the initial experience of using the Ponseti Method in the management of idiopathic clubfoot and to identify learning curve problems.

Materials and Methods: A retrospective analysis undertaken of 57 feet in 39 patients with CTEV treated by the Ponseti method. The standard protocol described by Ponseti was followed. Pirani’s clubfoot score was used to assess the deformity and the results of treatment. The follow-up in the study ranged from 3 months to 35 months. Denis Brown splints were used full-time for 3 months and at night for 1 year.

Results: 47 out of 57 feet had good results with no evidence of recurrence. 10 feet had recurrence and underwent further surgery. If compliance was poor with the Denis Brown splints or if there was a severe initial deformity there was an increased risk of recurrence. 20% had problems with the plaster of Paris cast and the foot slipped out of the Denis Brown splint in 14%. It was noted there were 2 cases of bruising and swelling associated with the removal of the cast and the application of Denis Brown boots which had not previously been reported.

Conclusion: This is only a preliminary study and therefore the long-term outcome cannot be assessed. It was noted that attention to detail and appropriate regular follow-up is important in achieving satisfactory results.

Low energy hip dislocation in children is an uncommon injury (0.335% of injuries ) which represents a true orthopaedic emergency.

Case 1 ; A 6 year old girl attended hospital non-weightbearing with right thigh pain after slipping whilst attempting to kick a football. The leg was shortened and internally rotated with no neurovascular deficit. Radiographs revealed a posterior dislocation of the right hip. A closed reduction was undertaken in theatre within four hours. She was immobilised in a hip spica for 6 weeks. At six month review she was pain free and back to full activities. Radiographs showed no abnormality.

Case 2 ; A 5 year old boy attended A+E non-weight-bearing with right lower leg and knee pain having done the splits playing football. Examination of knee and lower leg showed pain but nil else. Radiographs of the knee were normal. He was discharged with a diagnosis of possible ACL rupture. He re-attended 2 days later with immobility and increasing pain. Examination showed a 2cm leg length discrepancy. Radiographs revealed a posterior hip dislocation. He underwent a closed reduction in theatre. He progressed well under regular review until 5 months post-injury. He had increasing pain and decreasing range of movement. Radiographs showed trans-epiphyseal avascular necrosis. He therefore underwent a varus de-rotation osteotomy. One year on he has returned to full activities. He has a mild decreased range of movement. Radiographs show a flattened epiphysis and a united osteotomy.

Hip dislocation requires less trauma in children due to ligamentous laxity and a soft pliable acetabulum. Overall 64% are low energy and 80% are posterior dislocations. Complications include AVN, arthritis, nerve palsy and recurrent dislocation. AVN is 20 times more common if reduction is after 6 hours.

This report highlights the importance of thorough examination, accurate diagnosis and early treatment of paediatric hip dislocation.

This paper presents the results of forearm fractures in twenty children treated with flexible intramedullary nailing, over a period of 3 yrs.

Forearm fractures in children are an extremely common injury and excellent results are obtained in the majority of cases by closed reduction and plaster immobilisation. If adequate reduction cannot be achieved or maintained by conservative means or if it fails, some form of internal fixation will be required. Flexible nails are an extremely effective way for addressing this problem.

Twenty children had flexible intramedullary nailing done following forearm fractures over a 3-year period from 1997–2000 [failed reduction (10), unstable post MUA(3), slipped in plaster(6) and open fractures(1)]. There were 15 male and 5 female patients, the mean age being 10. 9. The nature of the injury were radial neck (3); proximal radius (1), galeazzi (1) and both bone fractures (15). Nine patients had closed nailing, while 11 required a mini open approach of which, 5 needed exposure only on one side. Patients were protected post surgery until signs of union were seen. The patients had regular clinical and radiological assessment and nails were removed on an average of 6–8 months, though in patients with radial neck fractures it was removed much earlier [4–5 weeks].

All patients went on to full bony union in excellent position, the average time to union being 5. 8 weeks. All but one patient regained full prono-supination, elbow and wrist motion, though none had any functional disability. There were a few minor complications especially following implant removal, including superficial wound infections (3), transient hypoasthesia in the distribution of the superficial radial nerve (2) and one patient in whom one nail had to be left behind as it could not be removed. There were no long-term sequelae.

Several methods of internal fixation are available, and the very diversity of choice demonstrates the lack of an ideal solution. K-wires are not applicable at all levels and plates have the disadvantage that they require extensive exposure of the fracture site. Removal of the plates is just as, if not more, fraught with complications.

Flexible nails can often be inserted closed, leave cosmetically more acceptable scars, provide excellent alignment of the fracture and can be removed easily without requiring any postoperative immobilisation. In our opinion it should be considered as the method of choice in treating forearm fractures in children, when some form of internal fixation is required.
