rhBMP-2 (Recombinant Human Bone Morphogenetic Protein-2) in real world spine surgery. A phase IV, National, multicentre, retrospective study collecting data from patient medical files in French spinal centres.

Background: This is a Phase IV, national, multicentre, retrospective study to observe the real-world use of rhBMP-2 in France.

Hypothesis: There was no statistical hypothesis, the statistical analyses were descriptive in nature.

Patients And Methods: Data was collected from patient medical files in 10 French spinal centres.

Three-month antibiotic therapy for early-onset postoperative spinal implant infections.

Background: Optimal duration and modalities of antibiotic therapy for early-onset spinal implant infection (EOSII) remain controversial.

Methods: Between November 2004 and November 2007, we conducted a prospective, monocentric study to assess the efficacy of a 3-month course of antibiotics for patients diagnosed with EOSII, as defined by a proven deep infection of the surgical site occurring within 30 days after spinal instrumented surgery. All patients with EOSII underwent surgical debridement with implant retention.

Influence of transforaminal lumbar interbody fusion procedures on spinal and pelvic parameters of sagittal balance.

Introduction: Restitution of sagittal balance is important after lumbar fusion, because it improves fusion rate and may reduce the rate of adjacent segment disease. The purpose of the present study was to describe the impact of transforaminal lumbar interbody fusion (TLIF) procedures on pelvic and spinal parameters and sagittal balance.

Materials And Methods: Forty-five patients who had single-level TLIF were included in this study.

Camptocormia: the bent spine syndrome, an update.

Camptocormia, also referred to as bent spine syndrome (BSS) is defined as an abnormal flexion of the trunk, appearing in standing position, increasing during walking and abating in supine position. BSS was initially considered, especially in wartime, as a psychogenic disorder. It is now recognized that in addition to psychiatric syndromes, many cases of reducible BSS have a somatic origin related to a number of musculo-skeletal or neurological disorders.

Neurological and functional outcome after unstable cervicothoracic junction injury treated by posterior reduction and synthesis.

Background Context: Unstable lesions of the cervicothoracic junction present a severe clinical problem for diagnosis, treatment, and prognosis.

Purpose: The objective of the present study was to evaluate the neurological and functional outcomes following surgical treatments which combine in all cases posterior reduction and stabilization.

Study Design: Retrospective clinical and radiological study.
