The gold standard technique for treating non-union of the clavicle is based on corticocancellous bone graft harvested from the iliac crest and fixation with a plate. In cases of large clavicular defects, this surgical procedure becomes ineffective and only a complex bone reconstruction can be considered. In the herein study we report on a clavicular non-union which was associated with a 4cm bone defect that was managed successfully with optimum fixation and the Chamber Induction Technique (C.I.T)-formation of the masquelet membrane- and subsequent biological augmentation with a composite bone graft...

OBJECTIVE: To compare the effectiveness of allograft and iliac crest autograft in atlantoaxial fusion. PATIENTS AND METHODS: Between January 2012 and December 2012, 41 consecutive patients underwent posterior atlantoaxial fusion with a screw-rod fixation system in our spine center. The choice to use allograft or iliac crest autograft was made by the patient himself or herself after being informed about the advantages and disadvantages of both methods. In the allograft group, we used mixed material of morcellized demineralized freeze-dried bone allograft and local autograft for posterior atlantoaxial fusion...

Sacral-iliac fixation techniques may be indicated in the management of various lumbosacral pathologies including spinal degeneration, infection, tumour resection, fracture, pseudarthrosis, correction of spinal deformities involving long fusion constructs to the sacrum and cases with poor sacral fixation. There are a number of options for lumbosacral fixation each with their own advantages and disadvantages. Though S2-alar-iliac (S2AI) have demonstrated promising advantages over alternatives, the complex anatomy of the spinopelvic region demands precise insertion of the screws to create a biomechanically robust construct safely...

Pelvic fractures are uncommon in children and account for between 0.3 and 7.5% of all pediatric injuries. Open pelvic fractures only account for up to 12.9% of all pediatric pelvic fractures. An unusual case of open complete anterior sacro-iliac joint dislocation in a 4-year-old boy is presented with a long-term follow-up. The multidisciplinary approach is reported with review of the current literature. A 4-year-old male presented to our institution in January 2012 after having been run over by a tractor. He presented with gross hemodynamical instability, MISS of 25, and an unstable lateral compression type III pelvic fracture with complete anterior dislocation of the left hemipelvis and a groin wound extending into the left thigh...

Closed reduction and percutaneous screw fixation (CRIF) of iliac crescent fractures and fractures of the anterior column of the acetabulum has become an established method in the treatment of these injuries. After reduction, safe insertion of a guide wire is a key step during this procedure. We present a technique that can facilitate introducing the guide wire under fluoroscopic guidance and allow for decreased radiation exposure.

Both-column fractures are the most complicated group of acetabular fractures. Although great progress of surgical technique has been made, the choice of approach is controversial. All the fragments could be exposed and managed through combined ilioinguinal and Kocher-Langenbeck (IL+KL) approaches, which has been widely used to conduct the both-column fractures. However, the clinical popularization may be restricted for high rate of complication. Most internal area of the hemipelvis could be exposed through Stoppa combined with iliac fossa (S+IF) approach...

Non-union of the humeral shaft is infrequently noticed after surgical fixation. Sixty eight patients whose osteosynthesis of humeral shaft had failed leading to non-union were identified over a duration of 10 years from (January 2006 to December 2015). Clinical and radiographical follow-up was available for 64 patients (4 patients were lost for follow-up), with a mean age of 58 years (range 25-78 years). All patients had aseptic atrophic non-union of either: proximal shaft (n=12), mid shaft (n=38), and lower shaft (n=14)...

Forearm fractures in children complicated with non-union are uncommon. Various methods have previously been reported to manage this condition. Well documented techniques would include iliac crest grafting, cancellous insert grafting, ulnar segment grafting, cortical tibial grafting, vascularized fibular grafting and bone transport by ring fixation. The authors present a case of a child with an atrophic non-union of the ulna who was successfully treated with a cortico-cancellous tibial strut bone graft.
