The choice of treatment for midshaft clavicular fractures is not straightforward, but depends on fracture characteristics such as comminution, angulation and displacement. An online survey was conducted amongst trauma and orthopaedic surgeons to determine the preferred treatment for midshaft clavicular fractures, based on anteroposterior radiographs, for 17 randomly selected displaced or comminuted midshaft clavicular fractures. The background and experience of the respondents were documented. ⋯ Locking plate fixation was more often preferred over other surgical modalities for comminuted than for displaced fractures (OR 1.50, 95% CI 1.17-1.91). In clinical practice, there is no consensus between surgeons on the choice of treatment for displaced or comminuted midshaft clavicular fractures. This lack of agreement calls for evidence-based treatment guidelines for these fractures.

The reconstruction of large bone defects in the infectious environment is still a big challenge for limb salvage because of disturbance in bacterial flora, bacterial resistance and limitation of blood supply at scarred tissue. This retrospective study was to evaluate long-term outcomes in patients who were performed vascularized fibular transfers for treatment of large bone defects in the infectious environment. The review included 26 patients with an average age of 27 years old. ⋯ Three patients had partial necrosis of skin paddle. Three patients, who were stabilized by screw and external fixator, had an infection at the distal part of the fibular graft and pin tracts. 25 fibular grafts (96%) showed complete bone union. This review has showed that the vascularized fibular transfer can be effective for management of large segmental bone defects in the infectious environment.

Comparative Study
Treatment of thoracolumbar burst fractures: short-segment pedicle instrumentation versus kyphoplasty.
The management of amyelic thoracolumbar burst fractures remains controversial. In this study, we compared the clinical efficacy of percutaneous kyphoplasty (PKP) and short-segment pedicle instrumentation (SSPI). Twenty-three patients were treated with PKP, and 25 patients with SSPI. They all presented with Type A3 amyelic thoracolumbar fractures. Clinical outcomes were evaluated by a Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) preoperatively, postoperatively, and at two years follow-up. Radiographic data including the anterior and posterior vertebral body height, kyphotic angle, as well as spinal canal compromise was also evaluated. The patients in both groups were similar regarding age, bone mineral density (BMD), follow-up period, severity of the deformity and fracture. Blood loss, operation time, and bed-rest time were less in the PKP group. VAS, ODI score improved more rapidly after surgery in the PKP group. No significant difference was found in VAS and ODI scores between the two groups at final follow-up (p > 0.05). Meanwhile, the height of anterior vertebrae (Ha), the height of posterior vertebrae (Hp) and the kyphosis angle showed significant improvement in each group (p < 0.05). The postoperative improvement in spinal canal compromise was not statistically significant in the PKP group (p > 0.05); there was a significant improvement in the SSPI group (p < 0.05). Moreover, these postoperative radiographic assessments showed significant differences between the two groups regarding the improvement of canal compromise (p < 0.05). At final follow-up, remodeling of spinal canal compromise was detected in both groups. ⋯ Both PKP and SSPI appeared as effective and reliable operative techniques for selected amyelic thoracolumbar fractures in the short-term. PKP had a significantly smaller blood loss and shorter bed-rest time, but SSPI provided a better reduction. Long-time studies should be conducted to support these clinical outcomes.

This retrospective study analyzed 276 cases of giant cell tumour of bone in the appendicular skeleton of patients first diagnosed and treated at the Orthopaedic Department of the West China Hospital in Sichuan University between 1988 and 2007. Fifty-eight percent of the tumours involved the knee region. The most common primary treatment was curettage (162 patients) combined with adjuvant local therapy. ⋯ Therefore, we recommend high-speed burring as a necessary adjuvant therapy. The combination of all adjuvants (burring, liquid nitrogen, and electro-cauterization) is recommended as a standard treatment. Cement filling of the cavity after curettage was not widely used in this series, but its merits have been reported in several studies; we therefore recommend that cement filling should be added to the adjuvants to be used after burring, liquid nitrogen and/or electrocauterization.

Management of intra-articular calcaneal fractures during the past years has ranged from the nihilistic approach of no active treatment to open reduction and internal fixation or even to early subtalar arthrodesis. Operative treatment presents the surgeon with many challenges. Good results require atraumatic exposure, anatomic reduction, rigid fixation and early mobilization. ⋯ The controlled distractive force provides numerous benefits. These include improved exposure of the subtalar joint, correction of angulation and maintenance of temporary stability prior to definitive fixation. We have found this technique applicable and easily reproducible.
