Background Many patients with X-linked hypophosphataemic rickets (X-LHPR) demonstrate significant lower limb deformity despite optimal medical management. This study evaluates the use of guided growth by means hemi-epiphysiodesis to address coronal plane in skeletally immature child. Methods Since 2005, 24 X-LHPR have been referred our orthopaedic unit for evaluation. All had standardised long leg radiographs that were analysed sequentially before and after surgery if any was performed. The...

PURPOSE OF STUDY: Prolonged bracing following injury in patients with Spinal Cord Injury without Radiographic Abnormality (SCIWORA) remains controversial. Some authors claim that there is occult instability and a risk of recurrent whereas others propose the spinal column will deform elastically, but return to its baseline stability by elastic recoil. We aim assess presence ligamentous on MRI incidence SCIWORA order determine need for prolonged bracing.  METHODS: A retrospective chart review...

Although non-surgical management is the mainstay of treatment for non-insertional Achilles tendinopathy, many patients fail to respond conservative measures. If symptoms persist after an extended period management, usually at least six months, surgery should be considered. Classically, open was performed with excision diseased areas tendon. Due a high rate complications, as much 10%, less invasive surgical techniques have been developed and are widely employed good outcomes far fewer...
