GeneXpert, a new, rapid molecular diagnostic test is recommended as the first line investigation for suspected pulmonary TB in areas of high HIV prevalence or drug resistance, yet it has not been validated for the diagnosis of musculoskeletal TB. The aim of this study was to assess the accuracy of GeneXpert for extraspinal musculoskeletal TB.Background:
Aim:
The question of prolonged bracing following injury in patients diagnosed with SCIWORA remains controversial. Proponents of the ‘Segmental Spinal Instability’ hypothesis claim that there is occult ligamentous injury leading to instability and a risk of recurrent injury. Published reports of recurrent SCIWORA involve patients with minor, transient neurological symptoms and normal MRI findings. The contradicting ‘differential stretch hypothesis’ is based on the premise that the spinal column will deform elastically, exceeding the elastic deforming potential of the more fragile spinal cord, but will return to its baseline stability. The purpose of this study is to evaluate the need for bracing in patients with SCIWORA based on MRI evidence of instability. A retrospective chart review was performed for a series of eleven patients with documented SCIWORA that presented to Red Cross Children's Hospital over the past 8 years. Details regarding mode of injury, age at presentation, neurological deficit at presentation, MRI findings and long term prognosis were documented. MRI's were reviewed by the authors as well as a consultant radiologist.Purpose of study:
Methods:
To evaluate the outcome of the Modified French osteotomy for the correction of cubitus varus resulting from a supracondylar distal humerus fracture in children. A retrospective review of 90 children, aged 3 to 14, who underwent a modified French osteotomy between 1986 and 2012 for the correction of cubitus varus as a result of a supracondylar distal humerus fracture. Case notes and radiographs were reviewed. The carrying angle was measured clinically and radiologically pre-operatively, post-operatively and at latest follow up. Comparison was made with the unaffected side. The outcome was graded as good if the correction of the carrying angle was within 5 degrees of the unaffected side, satisfactory if the correction was more than 5 degrees of the unaffected side but cubitus valgus was restored and poor if there was persistence of cubitus varus post correction. Any intra-operative and post-operative complications were documented.Purpose of the study
Description of methods
To determine the preferable treatment for congenital pseudarthrosis of the tibia, we retrospectively reviewed 19 patients (20 limbs) treated consecutively over a 22 year period (1988–2007). Fifteen were followed up to maturity. The patients were assessed for union, leg length discrepancy (LLD), ankle valgus, range of ankle movement and distal tibial physeal injury. The median age at surgery was 3 years. At surgery nineteen of the tibiae had a dysplastic constriction with a fracture (Crawford II-C or Boyd II) lesion. To obtain union in the 20 tibiae, 29 procedures were done. Nine failed primarily and required a second procedure to obtain union. Older patients (≥ 5 years) had a significantly higher success rate. Excision, intramedullary rodding and bone graft (IMR) was done in 14 tibiae: 10 (71.4%) were successful. Six of 10 primary operations and all 4 secondary operations after a previous failed procedure were successful. Ipsilateral vascularized fibula transfer (IVFT) was successful in 5 tibiae (3 primary and 2 secondary). Ilizarov with bone transport only, failed in two patients. Ilizarov with excision, intramedullary rodding and bone graft with lengthening was successful in 2 of 5 cases (40%); two sustained fractures at the proximal lengthening site. A median leg length discrepancy (LLD) of 3 cms occurred post surgery which was treated with contralateral epiphysiodesis. At maturity 3 patients had a LLD of ≥ 2cms. Six limbs had ankle valgus and were treated with stapling and tibio-fibular syndesmosis. Decreased range of movement of the ankle (< 50%) occurred in 7 patients. Distal tibial physeal injury occurred in 4 patients and was associated with repeated rodding.Aim
Results
Spontaneous intraarticular haemorrhages are the most frequent bleeding episodes encountered in the haemophiliac population, causing pain, joint deformity and arthropathy. Chronic haemophiliac arthropathy is characterised by persistent joint swelling, proliferative synovitis, and damage to or loss of articular cartilage. Elimination of the synovitis is the key to prevention of recurrent intraarticular haemorrhages and joint damage. The purpose of the study was to investigate the indications for, and outcome of, radioactive synoviorthesis for haemophiliac arthropathy. A retrospective study was done to assess the results of 12 intra-articular injections of radioactive Yttrium-90 colloid, performed in 10 patients from November 1993 to December 2006. Patients were referred by the Haematology Unit if they had a target joint, as defined as >2 bleeds into the same joint in the preceding 6 months. Follow up was conducted at 6 monthly intervals, assessing clinical and radiological outcomes. The radiological involvement of the target joint, the pre- and post-treatment range of movement, presence of synovitis and bleeding events were compared from presentation to that at follow up. Range of movement of each target joint was assessed and compared to that at follow-up.Purpose of the Study:
Methods:
Serial manipulations and casting for the treatment of congenital clubfoot has long been the practice internationally. There are, however, a great variety of manipulative techniques being practiced with differing results. We aim to determine how the rate of major surgery, ie. a full posteromedial-release (PMR), as initial surgical intervention has changed since introducing the Ponseti method of plastering at our centre in 2002. We also aim to determine whether pre-operative radiographs have any bearing on the type of surgery performed. Clinical records and radiographs of all patients presenting to our clubfoot clinic in the years 1999–2000 and 2009–2010 respectively were reviewed. Patients were included if they had clinical clubfoot, and excluded if they presented after 3 months of age, had undergone prior treatment or suffered from associated congenital anomalies. We then determined which patients underwent PMR as primary surgical intervention following serial castings. We also measured the radiographic parameters on all available radiographs (tibiocalcaneal, talometatarsal-I, lateral and AP talocalcaneal angles) and performed a statistical analysis to determine their value in predicting the type of surgery required.Purpose of study
Methods
Distal metaphyseal radial fractures are common in the paediatric population and the management of these fractures is controversial. The incidence of re-displacement in the closed management of these fractures is as much as 30% in some studies. Various methods have been described with the view to predict fracture displacement of distal radial fractures in children. One of these indices is the three point index (TPI). This index seeks to assess the adequacy of 3 point moulding and thus predict fracture displacement. It is a calculated ratio that if above 0.8 states that there is an increased risk of fracture re-displacement. The purpose of this study is to assess the accuracy of this index in predicting displacement of distal radial fractures in children. This retrospective study included 65 patients of both sexes under the age of 13 for a period of one year from January 2011 to January 2012. All patients with a dorsally displaced fracture of the distal radius were included. 22 patients were excluded because of loss to follow-up or absence of a complete series of x-rays. All patients were taken to theatre for a general anaesthetic and manipulation of their fractures using an image intensifier to confirm reduction. X-rays of initial fracture displacement, post manipulation position and follow-up fracture position at 2 and 6 weeks were assessed. The sensitivity, specificity, negative and positive predictive values of the TPI in screening for fracture re-displacement were calculated.Purpose
