Objective To compare 2 distraction osteogenesis techniques in post-traumatic tibial nonunion patients with composite bone and soft-tissue defects. Design Nonrandomized prospective, case series, single-center study. Setting Department of Orthopaedics and Traumatology, Limb Reconstruction Unit, El-Helal hospital, Cairo, Egypt. Participants Fifty post-traumatic tibial nonunion patients with composite bone and soft-tissue defects. Intervention Twenty-five patients were treated using bone transport (BT) technique, and 25 patients were treated using acute shortening (AS) and distraction technique. Outcome measurements The external fixation index (EFI); functional and bone results; and complication rates. Results All patients were followed for a minimum of 18 months after removal of their Ilizarov frame. AS and BT groups were followed up for a mean of 19.7 and 20.3 months, respectively. The mean bone gap after resection and debridement was 4 cm in AS group and 5.9 cm in BT group (P = 0.06). The mean EFI was statistically significant and lower in the AS group compared with BT group (P = 0.03). There were no other statistically significant differences between either intervention groups. Conclusions Both techniques achieved comparable good to excellent results, and the differences in number of complications and ASAMI scores for bone or function were not statistically significant. Yet, it appears that the AS technique may be superior because it has a significantly lower EFI. This may not be feasible in all cases, however, because the AS technique is limited by the defect size and the condition of the surrounding soft tissues. Level of evidence Therapeutic Level II.

STUDY DESIGN: Case Report. OBJECTIVE: To present a case of undifferentiated spondyloarthropathy with sternocostoclavicular arthro-osteitis and osteolyis of cervical body requiring surgical reconstruction of the spine and describing the findings which resembled multiple metastases or infection. SUMMARY OF BACKGROUND DATA: Sternocostoclavicular arthro-osteitis is not infrequent in Japan. It has been reported in patients with seronegative spondyloarthropathies as psoriatic arthropathy or its variant, palmoplantar pustulosis. Cervical spine involvement in the seronegative spondyloarthropathy is usually in the form of syndesmophytes, subluxations, or facet erosions/ fusions. To the best of our knowledge, this is the first report on severe osteolytic cervical spondylitis associating anterior chest wall disease, to the extent that surgical reconstruction is needed. METHODS: A 64 year-old woman presented with neck pain. Cervical spine imaging revealed osteolysis and crumbling of C5 vertebral body. Computed tomography of the thorax showed multiple erosions of the anterior chest wall. Multiple hot spots were detected by bone scan. Biopsies were obtained to exclude neoplasm and infection. Surgical reconstruction via combined anterior-posterior approach was performed to achieve solid spine arthrodesis. RESULTS: Neoplasm and infection were excluded. Careful reassessment alerted to the diagnosis of undifferentiated spondyloarthropathy. Solid arthrodesis and pain relief could be obtained by surgery together with medical control of the disease.
