Despite recent developments in fracture treatment, cases of non-union after long bone fractures are still encountered. This work aims at evaluating the active management of delayed union after the bridge-plate fixation of multifragmentary diaphyseal fractures by a limited surgical interference. Nineteen patients were included. ⋯ Bone grafting was added in nine patients. Union was achieved in all patients 8-16 weeks after re-operation. This work is a message for timely surgical interference in delayed union after bridge-plate fixation by a limited surgical procedure, before complete failure of the fracture stabilisation or non-union.

Although acute vascular injury is a common complication in children with severely displaced supracondylar humeral fractures, the management of patients with a pink pulseless hand still remains controversial. Between 1994 and 2006, 66 children with displaced supracondylar fractures of the humerus were treated. Five patients had an absence of the radial pulse with an otherwise well perfused hand. ⋯ Thrombectomy was performed, which led to the restoration of a palpable radial pulse. In one patient with open fracture, brachial artery contusion and spasm were found, and treated by removal of adventitia. Surgical exploration for the restoration of brachial artery patency should be performed, even in the presence of viable pink hand after an attempt at closed reduction.

The focus of this study was to examine the safety and effectiveness of three different discectomy techniques using a posterior approach for the treatment of herniated lumbar discs. There are only a small number of prospective randomised studies comparing posterior lumbar discectomy techniques, and no recent systematic review has been published on this matter. Using the Cochrane Collaboration guidelines, all randomised or "quasi-randomised" clinical trials, comparing classic, microsurgical, and endoscopic lumbar discectomies using a posterior approach were systematically reviewed. ⋯ Current data suggest that the microsurgical and endoscopic techniques are superior to the classic technique for the treatment of single level lumbar disc herniations with respect to volume of blood loss, systemic repercussions, and duration of hospital stay. All three surgical techniques were found to be effective for the treatment of single level lumbar disc herniations in patients without degenerative vertebral deformities. No conclusions could be drawn from the clinical randomised studies reviewed regarding the safety of the three techniques studied due to insufficient data on postoperative complications.

Randomized Controlled Trial
A comparative study of internal fixation and prosthesis replacement for radial head fractures of Mason type III.
Although several treatment options for radial head fractures are available, no clear solutions exist. In this study we therefore compare open reduction and internal fixation (ORIF) with bipolar radial head prosthesis replacement in treatment of radial head fractures of Mason type III. Cement stem and bipolar radial prosthesis were used to treat 12 fresh cases and two old cases of Mason type III radial head fracture. ⋯ The result was good or excellent in 92.9% of prosthesis replacement patients and in 12.5% of ORIF patients. This difference is statistically significant (P = 0.0004; Fisher's exact test). We concluded that bipolar radial head prosthesis replacement is better than ORIF in treatment of Mason type III radial head fracture.

The objective of this paper was to investigate the surgical strategy of the selection of the lowest instrumented vertebrae (LIV) in anterior correction for adolescent idiopathic scoliosis (AIS) and to discuss the relationship between the LIV and trunk balance. From 1998 to 2004, 28 patients with thoracolumbar/lumbar AIS (Lenke 5 type) were treated by anterior correction and fusion with a mean follow-up of 1.5 years. Specific radiographic parameters were observed respectively and the correlation between disc wedging immediately below the LIV and these parameters was analysed. ⋯ The postoperative LIV-CSVL (centre sacral vertical line) distance, which reflects regional balance, was correlated with various preoperative parameters. LIV determination was correlated with multiple preoperative radiographic parameters. Disc wedging distal to LIV occurs most often when a short fusion excluding the lower end vertebra (LEV) and the subjacent disc are nearly parallel.
