Fixation techniques used in the treatment of slipped capital femoral epiphysis (SCFE) that allow continued growth of the femoral neck, rather than inducing epiphyseal fusion in situ, have the advantage of allowing remodelling of the deformity. The aims of this study were threefold: to assess whether the Free-Gliding (FG) SCFE screw prevents further slip; to establish whether, in practice, it enables lengthening and gliding; and to determine whether the age of the patient influences the extent of glide. All patients with SCFE who underwent fixation using FG SCFE screws after its introduction at our institution, with minimum three years’ follow-up, were reviewed retrospectively as part of ongoing governance. All pre- and postoperative radiographs were evaluated. The demographics of the patients, the grade of slip, the extent of lengthening of the barrel of the screw and the restoration of Klein’s line were recorded. Subanalysis was performed according to sex and age.Aims

A national screening programme has existed in the UK for the diagnosis of developmental dysplasia of the hip (DDH) since 1969. However, every aspect of screening and treatment remains controversial. Screening programmes throughout the world vary enormously, and in the UK there is significant variation in screening practice and treatment pathways. We report the results of an attempt by the British Society for Children’s Orthopaedic Surgery (BSCOS) to identify a nationwide consensus for the management of DDH in order to unify treatment and suggest an approach for screening. A Delphi consensus study was performed among the membership of BSCOS. Statements were generated by a steering group regarding aspects of the management of DDH in children aged under three months, namely screening and surveillance (15 questions), the technique of ultrasound scanning (eight questions), the initiation of treatment (19 questions), care during treatment with a splint (ten questions), and on quality, governance, and research (eight questions). A two-round Delphi process was used and a consensus document was produced at the final meeting of the steering group.Aims
Methods
The aim of this study was to establish the incidence of developmental dysplasia of the hip (DDH) diagnosed after one-year of age in England, stratified by age, gender, year, and region of diagnosis. A descriptive observational study was performed by linking primary and secondary care information from two independent national databases of routinely collected data: the United Kingdom Clinical Practice Research Datalink and Hospital Episode Statistics. The study examined all children from 1 January 1990 to 1 January 2016 who had a new first diagnostic code for DDH aged between one and eight years old.Aims
Patients and Methods
The aim of this study was to quantify the risk of developing cancer from the exposure to radiation associated with surgery to correct limb deformities in children. A total of 35 children were studied. There were 19 girls and 16 boys. Their mean age was 11.9 years (2 to 18) at the time of surgery. Details of the radiological examinations were recorded during gradual correction using a Taylor Spatial Frame. The dose area product for each radiograph was obtained from the Computerised Radiology Information System database. The effective dose in millisieverts (mSv) was calculated using conversion coefficients for the anatomical area. The lifetime risk of developing cancer was calculated using government-approved Health Protection Agency reports, accounting for the age and gender of the child.Aims
Patients and Methods
When transferring tissue regenerative strategies
involving skeletal stem cells to human application, consideration needs
to be given to factors that may affect the function of the cells
that are transferred. Local anaesthetics are frequently used during
surgical procedures, either administered directly into the operative
site or infiltrated subcutaneously around the wound. The aim of
this study was to investigate the effects of commonly used local anaesthetics
on the morphology, function and survival of human adult skeletal
stem cells. Cells from three patients who were undergoing elective hip replacement
were harvested and incubated for two hours with 1% lidocaine, 0.5%
levobupivacaine or 0.5% bupivacaine hydrochloride solutions. Viability
was quantified using WST-1 and DNA assays. Viability and morphology
were further characterised using CellTracker Green/Ethidium Homodimer-1
immunocytochemistry and function was assessed by an alkaline phosphatase
assay. An additional group was cultured for a further seven days
to allow potential recovery of the cells after removal of the local
anaesthetic. A statistically significant and dose dependent reduction in cell
viability and number was observed in the cell cultures exposed to
all three local anaesthetics at concentrations of 25% and 50%, and
this was maintained even following culture for a further seven days. This study indicates that certain local anaesthetic agents in
widespread clinical use are deleterious to skeletal progenitor cells
when studied
The incidence of metastatic osteosarcoma is increasing because of improved results following multi-agent chemotherapy and resection of the primary tumour. Metastases occur most commonly in the lungs, whereas bowel metastases are rare. We describe a 25-year-old female who presented with melaena six years after successful resection of an osteosarcoma of her right femur, and one year after resection of a solitary pulmonary metastasis. Imaging revealed a lesion arising within both the duodenum and the pancreas for which a Whipple’s pancreatoduodenectomy was carried out, achieving complete resection. Histological examination confirmed the diagnosis of metastatic osteosarcoma. We believe this is only the second such case reported. At 11 months post-operatively she had no detectable disease. Although rare, osteosarcoma can metastasise to the intestine. The surgeon must be aware of this complication, and that bowel metastases are potentially resectable.
