BACKGROUND: Anterior discectomy and fusion have been used for over 50 years in the treatment of degenerative disease of the cervical spine. However, as these procedures become more common, the long-term consequences are becoming more evident. One such consequence is degeneration of an adjacent segment, which can occur in up ...

Few studies have focused on the long-term results of triple arthrodesis in patients with rheumatoid arthritis. We retrospectively reviewed fusion rate, arthritis of the adjacent joints, clinical outcome, and patient satisfaction. Between 1990 and 1998, 28 patients with rheumatoid arthritis were managed with a total of 32 triple arthrodeses. Of ...

BACKGROUND: Intermediate-term radiographic studies have shown that anterior and circumferential techniques result in high fusion rates in patients with high-grade spondylolisthesis, whereas posterolateral fusion is less successful. We are not aware of any long-term comparative studies in which these three methods have been evaluated with regard to functional outcome, including ...

OBJECTIVE: Anterolateral partial oblique corpectomy (OC) aims to decompress the cervical spinal cord without subsequent fusion and saves the patient from graft-, instrument-, and fusion-related complications. Although it is a promising technique, there are few studies dealing with its efficacy and safety. METHODS: In this prospective study, 40 consecutive patients ...

Currently available therapeutic options for the correction of osteoporotic posture changes are not effective. Rigid or semi-rigid orthoses are only applicable in the early phase after vertebral body fractures, and the knowledge about the efficacy of flexible spinal orthoses is limited. Therefore, the present study is aimed at investigating the ...

A variety of bone graft substitutes, interbody cages, and anterior plates have been used in cervical interbody fusion, but no controlled study was conducted on the clinical performance of beta-tricalcium phosphate (beta-TCP) and the effect of supplemented anterior plate fixation. The objective of this prospective, randomized clinical study was to ...

STUDY DESIGN: Prospective cohort study. OBJECTIVE: We propose a simple outcome-based classification for assessment of pedicle screw positions based on postoperative computed tomography scan.

The conservative treatment of adolescent idiopathic scoliosis (AIS) has traditionally been divided into two phases-correction and stabilisation-and casts, even if less used today, can be considered the best standard in the correction phase. Till the present, however, no comparison between cast and brace efficacy has been proposed. This is a ...

A retrospective analysis of first metatarsophalangeal joint fusion in 26 consecutive patients (34 feet), treated between April 1998 and February 2002, comparing single compression screw versus a compression screw supplemented with a dorsal quarter tubular plate, was undertaken. The study aimed to assess whether or not plate augmentation of the ...

OBJECT: Gross-total resection of pediatric intramedullary spinal cord tumor (IMSCT) can be achieved in the majority of cases while preserving long-term neurological function. Nevertheless, postoperative progressive spinal deformity often complicates functional outcome years after surgery. The authors set out to determine whether laminoplasty in comparison with laminectomy has reduced the ...

The clinical evaluation, even today, remains a central point in the diagnosis, prognostic definition and treatment prescription regarding scoliosis. The clinical evaluation of a scoliotic patient has been established for a long time, but it has not been standardized. The aim of the present work is to report the most ...

OBJECT: Patient selection is perhaps the most important factor in successful lumbar surgery. In this study, the authors analyzed the clinical outcomes of patients enrolled in the CHARITE investigational device exemption (IDE) trial who underwent revision surgery after primary total disc replacement with CHARITE or an anterior lumbar interbody fusion ...

Object Lumbar spondylolysis occurs in approximately 6% of the population and presents with localized mechanical back pain, often in young athletes. Surgical treatment may involve decompression, lumbar intersegmental fusion, or direct repair of pars defects. Although such open procedures may effectively resolve symptoms, minimal-access approaches may additionally decrease collateral damage ...

In the study reported here, we retrospectively evaluated short-term results of knee arthrodesis using the Wichita fusion nail (WFN) in patients with active infection.
