Purpose

The decision to undertake prophylactic pinning to prevent contralateral slipped upper femoral epiphysis (SUFE) remains controversial; we hypothesised that the grade of initial SUFE could predict the grade of a second SUFE and risk of poor outcome.

Method

We retrospectively reviewed radiographs of all children who presented to Alder Hey with a new diagnosis of SUFE between 2007–2014. Of those who developed a contralateral SUFE, grade of first and second SUFE was determined radio-graphically using % slip and Southwick angle on frog lateral radiograph.

Tropical pyomyosistis is an uncommon condition in the United Kingdom. Early diagnosis and appropriate treatment are crucial for a good outcome. We had seen 13 cases in our previously published series from 1998 to 2009. This is an update showing a significantly increased incidence from 2010 to 2016.

A retrospective review of all cases of pelvic pyomyositis in our centre from January 2010 to April 2016 was undertaken from case notes and radiology reports. All children with clinical and radiographic evidence of pyomyositis were included. Since our previous publication we had changed our practice to get an MRI scan in all children who presented with a limp, fever and raised inflammatory markers, and had no effusion in the hip ultrasound scan.

We identified 24 children with a mean age of 7 years (range, 1 week to 14 years). MSSA (Methicillin-Sensitive Staphylococcus aureus) was the most common cultured organism (n=8). Median hospital stay was 9 days (3 to 12). Obturator internus was the most common muscle affected. All patients had appropriate antibiotics with 2 patients requiring surgical drainage of abscesses. The majority of children (n=22) showed a complete recovery with antibiotics only.

Incidence of pyomyositis has increased dramatically in our population and early diagnosis can result in a good outcome. We recommend MRI scan in all patients who present with a clinical picture of septic arthritis of the hip but with no effusion.

The aim of this study is to discuss the results of intramedullary devices in the management of paediatric radial neck fractures and to suggest methods to avoid the pitfalls of the technique.

30 patients with isolated Judet III and IV fractures were included in this retrospective study. The method of reduction was reviewed. The final results were graded using the Metaizeau functional scoring system and Oxford Elbow score.

Intramedullary K wires were used in 10 patients and blunt tipped TENS nails in 20 patients. The complications seen were radiocapitellar joint penetration-6 cases at mean 4.87 weeks, redisplacement − 6, radial epiphyseal sclerosis − 5 and heterotopic ossification − 1 case. The functional result was good to excellent in 24 of 30 cases(80%). The mean Oxford Elbow score was 44.32. The mean follow-up was 40.11 months.

Intramedullary K wires may result in radiocapitellar joint penetration. Blunt tipped devices should not be used as purely fixation devices as they may not prevent redisplacement. Minimal redisplacement does not affect the functional outcome.

Regular follow-up until atleast 6 weeks is essential. Patients who have a Judet IV fracture and need open reduction should be closely followed up and given a guarded prognosis.

We report our early experience with distracting external fixation used to offload the hip after avascular necrosis (AVN) of the femoral head secondary to severe slipped upper femoral epiphysis (SUFE).

A case series of five patients treated in a tertiary centre is reported. Electronic case records and radiographs were reviewed. Data recorded included demographics, initial presentation, timing of head collapse, timing and duration of distraction and outcome including referral to adult arthoplasty services.

Mean age at presentation was 12 years (range 12–15). 4 were females. Initial treatment in 4 cases was a delayed cuneiform osteotomy and pinning, one patient underwent serendipitous reduction and percutaneous pinning. Mean duration to initial surgery was 10 days (range 5–16). All patients had femoral head collapse at a mean of 148 days from time of presentation. 2 patients required backing out of screws due to intra-articular protrusion. All patients underwent distraction at a mean 193 days from presentation. Average distraction achieved was 10 mm and duration of application was 125 days (range 91–139)

All patients experienced improvement or resolution of pain but persistence of poor function, characterised by fixed adduction and limb length discrepancy. 3 patients were referred to adult arthroplasty services.

This may be an effective treatment option for pain associated with AVN post SUFE. However, in our experience normal anatomy and function of the hip is not restored if performed after collapse of the femoral head. Consideration should be given to application of the distractor either at the time of initial fixation or prior to femoral head collapse. Authors believe that timing of the application of the distractor is critical for a successful outcome and recommend a prospective study with large numbers.

Introduction

Some patients with Cerebral Palsy who had a de-rotation osteotomy performed for correction of excessive anteversion had persistence of internal foot progression even after surgery. Potential causes which have been implicated include: weak hip abductors, spasticity of the anterior fibres of the gluteus medius, hip adductor spasm and persistent femoral anterversion. The aim of this study was to see if there is any relationship between significant abductor weakness [less than Grade III: MRC] and persistence of internal foot progression.

Methods

We included all ambulatory patients with cerebral palsy who had had a derotation osteotomy between the periods of 2000-2005, who had also had a pre and post operative gait analysis, assessment of anteversion [Gage Test], hip range of motion and muscle charting.

There were 12 patients [17 hips, 5 bilateral] with an average age of 13. Seven were diplegic, two hemiplegic and three had asymmetric diplegia. Data was assessed using SPSS13.0. The Spearman Co-relation Coefficient was used to test if there was any correlation.

A significant proportion of children with cerebral palsy (CP) are malnourished. This is particularly the case for trace elements, vitamins and minerals. Children with CP undergoing major orthopaedic procedures lose blood intra operatively leading to post operative anaemia. The aim of our study was to estimate the prevalence of low levels of serum ferritin in children with CP awaiting major orthopaedic surgical intervention.

The ferritin levels and haemoglobin (Hb) were estimated pre-operatively in 35 children with CP (CP group) undergoing major orthopaedic surgery (Hip reconstruction or Single event multi-level surgery). During the same period, we randomly identified 1000 children (Control group) who underwent Ferritin estimation as part of routine investigations. A significant proportion of children in the study group had low levels of serum ferritin in spite of having normal haemoglobin.

It is well-recognised that commencement of iron either orally or intravenously in the post-operative period does not accelerate recovery from anaemia secondary to blood loss. It is important to note that many patients who have normal Hb levels preoperatively are iron deficient. Hb estimation alone is inadequate in this group. We therefore conclude that children with cerebral palsy undergoing major orthopaedic surgery must have their ferritin levels estimated and optimised well in advance of their surgery.

Primary pyomyositis is increasing in incidence in the western world. Although a commonly encountered condition in the tropics it was not described in the USA until 1971 and the UK until 1998. The reason for the increasing incidence is not understood.

Typically pyomyositis affects the muscles around the hip and may present in a variety of ways to orthopaedic or general surgeons – occasionally leading to unnecessary operative intervention. We sought to identify the experience gained, of this condition, within a UK paediatric tertiary referral unit.

A retrospective review of cases of pyomyositis, from our institution, since 1998 was undertaken to identify demographics, presentation, diagnosis and management. Thirteen cases of pyomyositis were identified. Obturator internus was most commonly affected (n = 7). Trauma was implicated in three cases and group A staphylococcus was cultured in nine cases. Male:Female ratio ~ 3: 2. Initial working diagnosis at presentation was septic joint in eight cases, appendicitis in three cases and soft tissue abscess in two cases. Ten cases settled with antibiotics alone. One diagnostic retroperitoneal exploration was performed which may have been avoided with greater preoperative awareness of this condition. On reflection, all cases were identified by CT or MRI.

To our knowledge, this is the first UK series of pyomyositis, reflecting its increasing incidence in the western world. Its presentation is similar to other common paediatric surgical emergencies, yet its management is very different – often not requiring surgery. A greater awareness of this emerging condition is therefore essential to both general and orthopaedic surgeons in order to prevent misdiagnosis and unnecessary surgical intervention.

Aim: To describe the epidemiology of paediatric bone infections in a single health district in England with particular reference to incidence and the changing pattern of the disease.

Method: Cases of chronic osteomyelitis and chronic regional multifocal osteomyelitis were excluded leaving 53 children diagnosed with acute haematological osteomyelitis (AHO) at a paediatric orthopaedic unit between January 2000 and December 2005. Patients were identified from the hospital coding system using the keywords ‘bone infection’ and ‘osteomyelitis’. The data were collected retrospectively from the patients’ hospital records and included demographic information, the delay between symptoms and presentation, clinical presentation, site of infection, organisms identified and laboratory results.

Results: The mean age of presentation was 40 months (range 0.5–179). The highest age incidence was between 0–3 yrs. There was no sex predilection with 27 girls and 26 boys. The mean duration of symptoms before presentation was 3.4 days (range 0–14 days). The presenting symptoms were pain at the affected site in 100% of cases, pyrexia (temperature > 38°C) in 47.1%, swelling of the affected site in 47.1%. The commonest bone affected was the femoral metaphysis. The commonest bacterium isolated was staphylococcus aureus. WBC, CRP and ESR were elevated in 44%, 84% and 92.1 % of the cases respectively. Plain radiographs and bone scan demonstrated signs of osteomyelitis in 32.1% and 78.8 % respectively. Surgical intervention was required in 21 patients.

Conclusions: The demographics and clinical presentation of AHO has not changed over the years. The commonest organism involved remains Staphylococcus aureus. ESR and bone scans were the most sensitive screening test for diagnosing the condition. Early initiation of third generation cephalosporin antibiotic therapy and surgical decompression, when necessary, was the mainstay of treatment.

Purpose of Study: To discuss on Clinical presentations, Investigations, Histopathology, Differential diagnosis and Treatment options based on a series of six Lipoblastomas that we encountered in our paediatric orthopaedic practice.

Materials and Methods: This series consists of six children with lipoblastoma who attended Alder Hey Hospital between 2000 and 2006. Mean age 17 months. Mean follow up was 26 months. The youngest was a six month old infant with a swelling on his right instep. The second patient was a three year old girl who 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, fourth patient had a swelling of his left thigh and two patients had swellings in their back. They were investigated appropriately with MRI, CT or USG and surgical excision planned accordingly.

Results: Male to female ratio was 5:1. Age groups; 2 patients were of less than 12 months of age, another two of them was between 12 to 24 months and the last two were under 36 months at the time of diagnosis. Anatomically three patients had swellings in the lower limb, 2 had swellings over dorsum of their trunk one patient had a forearm swelling.

Investigations include MRI for one patient and CT for another USG was done for the remaining four. There was no post op complication for any of them. None of them have shown any recurrence during the follow-up.

Discussion: Lipoblastomas are uncommon, benign tumour of embryonal mesenchymal cells. It is a rare tumour but occurs mostly during infancy and early childhood. It most often presents on the extremities, back, head and neck.

Histology: cellular neoplasm composed of lipoblasts in different stages of maturation and fine vascular network, with well defined septa.

Cytogenetic evaluation often shows chromosomal anomalies of tumour cells like abnormalities of the long arm of chromosome 8, leading the rearrangement of the PLAG1 gene. Biopsy of the lesion is recommended, as clinical and radiological diagnoses can be misleading.

These tumours tend to spread locally and may recur in case of incomplete resection; metastatic potential has not been reported.

Differential diagnosis includes myxoid liposarcoma, welldiffrentiated liposarcoma, spindle cell lipoma, typical lipoma and soft tissue sarcoma.

Conclusion: All patients were originally thought to have simple lipomas or soft tissue swellings. This is primarily because lipoblastoma is a rare tumour and is rarely encountered in orthopaedic training. It is important that we orthopaedic surgeons be aware that lipoblastoma is in fact the most likely diagnosis of a fatty lump in a child of less than two years of age. Lipoblastomas needs through imaging and if possible cytogenetic evaluation for accurate diagnosis before surgery because complete surgical resection is mandatory to prevent a likely local recurrence.

Background: Tourniquet provides a blood less field for surgery, but it has few complications and contraindications. There are several studies identifying the tourniquet as a factor for increased risk of complications in knee arthroscopy, we reviewed 200 consecutive knee arthroscopies done in our hospital with out tourniquet to analyse the outcome.

Aim: To analyse the out come of 200 knee arthroscopies with out use of tourniquet; with respect to visualisation, time of surgery, bleeding, analgesia and post operative complications.

Materials and methods: We retrospectively analysed 200 consecutive knee arthroscopies with out tourniquet done in our institute. Average age of these patients was 39 (21–81). All patients underwent soft tissue procedures under general anaesthesia, supine, with sole support, no antibiotics and was done by same surgeon as day case. Same arthroscopic kit with pump was used for all patients, using 2 litre saline bag and pump set at 65 mm Hg pressure. First few cases had tourniquet applied but not inflated, but later even this was avoided. Procedures included were diagnostic arthroscopies, arthroscopic debridements, meniscal repairs and partial or complete meniscal resections. Procedures like arthroscopic ACL reconstruction and other bony procedures were excluded. We looked at any visualisation problems, time of surgery, bleeding, analgesia and post operative complications. We also looked weather any of these patients visited the consultant or GP for any wound related problem or pain before the usual review at 2 weeks.

Results: There was no problem with visualisation noted in any of the cases, or any incidence where arthroscopy was unduly prolonged. There was no incidence of bleeding, stiffness or increased need for analgesia in any of these patients. None of the patients had any wound problem or haemathrosis requiring intervention. There was no record of any patients reattending the clinic or their GP for pain or bleeding.

Conclusions: Many orthopaedic units continue to use a tourniquet routinely for soft tissue procedures in knee arthroscopy, probably in the belief that a clear operative view can only be achieved with one. However, the findings in our study indicate that knee arthroscopy for soft tissue procedures may be performed adequately without the use of a tourniquet provided a pump system is used and the pressure maintained above venous pressure. Therefore we recommend that its use for routine soft tissue arthroscopic procedures be discontinued.

To assess the outcome and implant removal rate following surgical stabilisation of patella fracture.

Sixty-seven patients who underwent surgical stabilisation of patella fracture between January 1999 and December 2004 were retrospectively reviewed to determine the adequacy of fracture stabilisation, fracture union and implant removal rate.

Forty-three were men and 24 were women with a mean age of 49 years (ranged 14–90 years). Table below demonstrates the injury, fracture patterns and fixation methods. There were 3 open fractures and associated injuries were noted in 22 patients. All fractures united even though the fixation was inadequate in 46 patients. Two superficial infections responded to oral antibiotics. One patient had revision surgery at 6 weeks. Twenty-two patients required implant removal between 2 and 20 months (average 11 months) for implant related symptoms. Of the 22 (32.8%) patients requiring implant removal, 16/40 (40%) were less than 60 years and 6/27 (22.2%) were over 60 years. Mean follow up in asymptomatic patients was 8 months (3 to 18 months) and in patients with implant related problems was 17 months (10 to 36 months). Four patients were lost to follow up.

Surgical stabilisation by current techniques demonstrated satisfactory fracture union. However, one in three required second surgery for implant related symptoms. In the under 60 years group, the implant removal rate increased to 40%. Newer techniques to avoid skin irritation need to be considered.
