Chronic infection (CO) and infected non-union of the long bones are relatively rare conditions in paediatric patients. Large bone defects secondary to these conditions can be managed with the induced membrane technique. The technique requires grafting of the bone void, although it is not yet established what bone substitute is the best option. The aim of this work was to evaluate the outcome and efficacy of treatment in children with CO and infected non-union of the long bones using the induced membrane technique and bone (BG) versus beta-tricalcium phosphate (BTP) grafting. ⋯ The induced membrane technique with BG or BTP graft can achieve bone healing in large bone defects secondary to CO and infected non-union in children and adolescents. The choice of bone substitute is important. Our preliminary results show graft integration and bone healing can be expected sooner if BTP is used as bone void filler.

Randomized Controlled Trial
Comparison of dry needling and steroid injection in the treatment of plantar fasciitis: a single-blind randomized clinical trial.
Plantar fasciitis is a common cause of heel pain. Considering different interventions which are applied for patients with plantar fasciitis, dry needling is proposed as a new modality of treatment recently. The aim of this study is to evaluate the effectiveness of dry needling versus steroid injection for plantar fasciitis. ⋯ Steroid injection can palliate plantar heel pain rapidly but dry needling can provide more satisfactory results for patients with plantar fasciitis in the long term.

Comparative Study
Effect of a collar on subsidence and local micromotion of cementless femoral stems: in vitro comparative study based on micro-computerised tomography.
The aim of this study is to quantitatively compare the difference in primary stability between collarless and collared versions of the same femoral stem. Specifically, we tested differences in subsidence and micromotion. ⋯ Primary stability was achieved for both stem designs, with a mean micromotion below the osseointegration threshold. Under loading conditions similar to those observed in normal daily activity and with good press-fit, the collar had no influence on subsidence or micromotion. Further studies are required to test the potential advantage of collar with higher loads, undersized stems, or osteoporotic femurs.

This study aimed to provide preliminary evidence regarding effectiveness of grafting beta-tricalcium phosphate (β-TCP) combined with a cancellous autograft for treating nonunion of long bones in the lower extremity due to infection by evaluating clinical and radiological outcomes. ⋯ Our findings suggest that β-TCP may be an effective extender when using the induced membrane technique.

Hook plate fixation is widely used to treat acromioclavicular joint dislocation. However, there are many post-operative complications affecting the effect of treatment. The aim of this study is to evaluate the efficacy of the clavicular hook plate with different hook angles as a method of treatment in AC joint dislocation, and to guide the clinical application of hook plate. ⋯ Hook plate treatment for AC joint dislocation can achieve the desired results, but the efficacy was significantly different depending on the different angles of the hook plate. AHP should be controlled within the range of 0-40° as much as possible when making clinical decisions.
