Aims

To determine the value of scoliosis surgery, it is necessary to evaluate outcomes in domains that matter to patients. Since randomized trials on adolescent idiopathic scoliosis (AIS) are scarce, prospective cohort studies with comparable outcome measures are important. To enhance comparison, a core set of patient-related outcome measures is available. The aim of this study was to evaluate the outcomes of AIS fusion surgery at two-year follow-up using the core outcomes set.

Background

Combined physical and psychological (CPP) programmes are widely recommended for Chronic Low Back Pain (CLBP) patients, but not often implemented. Patients with longstanding CLBP participating in a two-week CPP programme improve in functional status and quality of life and this is maintained at two-year follow up. One-year follow-up data is available of 955 participants.

Purpose: The long term effects of treatment in a cohort of patients with chronic low back pain (CLBP) participating in an intensive pain management program.

Background: Cognitive behavioral treatments produce clinically relevant benefits for patients with CLBP.

Methods: The program provided by RealHealth-Netherlands is based on cognitive behavioral principles and executed in collaboration with orthopedic surgeons. Primary outcomes were daily functioning and self-efficacy. Measurements were at baseline, last day of residential program and at 1 and 12 months follow-up. A GLM procedure with repeated measures was applied to examine changes over time and to explore possible unwanted side effects. Effect sizes are analyzed using cohen’s d. Clinical relevance was examined using minimal clinical important differences (MCID) estimates for primary outcomes and quality of life. To compare results with literature Standardized Morbidity Ratios (SMR) were determined.

Results: 107 patients with CLBP participated. Mean scores on primary and secondary outcomes showed a similar pattern: improvement immediately after following the program and maintenance of results over time. Effect sizes were 0.9 for functioning and 0.8 for self-efficacy. Clinical relevancy: 79% reached MCID on functioning, 53% on self-efficacy and 80% on quality of life. Found study results were 36% better and 2% worse when related to previous research on respectively rehabilitation programs and spinal surgery for similar conditions (SMR 136% and 98%respectively).

Conclusion: The participants of this evidence based program learned to manage CLBP, improved in daily functioning and quality of life. The study results are comparable with results of spinal surgery and even better than results from less intensive rehabilitation programs.

Background: Surgical treatment of spinal deformities is complex and is performed by a limited number of spine surgeons. To obtain adequate radiological and clinical correction, a large amount of clinical experience is required when planning corrective surgery because of the enormous amount of patient related variables, and the many surgical techniques (e.g. rod rotation vs translation, pedicle screws vs hooks, anterior vs posterior).

The widely used classification systems (King and Lenke) are useful for documentation of the deformities. Unfortunately explicit guidelines for surgery are not clear. A multi-centre database with pre and postoperative patient data including photographic images and x-rays will be very useful in decision making. It will allow surgeons to find similar cases in the database that will help them in their decision making for surgical planning and execution. Furthermore it will provide extensive data to perform outcome studies, and to develop general treatment guidelines. Surgery for spinal deformities will become more evidence based and less dependent on the individual surgeons judgement.

Methods: A modern web-based database system, Scolisoft was developed for documenting patient data and curve characteristics. The system contains patient data (demographics etc), radiological data (AP, Lat, bending films), classification of curve patterns according to the often-used classification systems and information about the surgical procedure. It includes pre and postoperative radiological data and clinical photographs.

The patient data can also be stored and printed as a PDF-file, so that it can be used as a patient chart and for patient information purposes.

Scolisoft allows the user to select patients based on all the individual characteristics, e.g. curve classification. For pre-operative planning of a specific deformity, a cohort of patients with the same deformity (patient demographics, curve pattern, bending films etc) can be selected and the postoperative results viewed.

With the same selection tool, cohorts of patients can be selected for outcome studies.

Furthermore Scolisoft provides the possibility of discussing difficult cases with other spine surgeons using the system.

Finally, complications are registered according to the existing Scoliosis Research Society complication registry system.

Experiences: Data of more than 200 patients have been entered into the former PC application system. The current web based system has 60 cases that have been entered during its trial phase. Most cases have been adolescent or adult idiopathic scoliosis. Forty two surgeons have used the software and eight surgeons have participated in entering cases. The web-based version has shown to be very user friendly. Submitting the radiological and clinical images is easy (but takes some time). All data input is possible by a simple click of the mouse. Therefore it is relatively easy to learn.

The system already has the possibility for documenting other spine pathology such as sagittal plane deformities, fractures and spondylolisthesis.

Conclusion: Scolisoft is a powerful, user-friendly web-based registry for spinal deformities. It is a very useful tool in planning spinal deformity surgery and research. In this time of evidence-based medicine, it is time to take the planning of scoliosis surgery out of the realm of myth, and this database is a strong step in that direction.

We report the long-term results of 51 pelvic osteotomies in 43 patients with a mean follow-up of 15 years (13 to 20). The mean age of the patients was 28 years (14 to 46). At review three patients were lost to follow-up, and six had received a total hip arthroplasty. Of 48 hips, 42 (88%) were preserved, with good to excellent clinical results in 27 (64%). Pre-operatively, 41 (80%) of the treated hips had shown no sign of osteoarthritis. Thirty-one (65%) hips showed no progression of osteoarthritis after follow-up for 15 years. Significant negative factors for good long-term results were the presence of osteoarthritic changes and a fair or poor clinical score pre-operatively. Pelvic reorientation osteotomy for symptomatic hip dysplasia can give satisfactory and reproducible long-term clinical results.

Reorientation of the acetabulum may be required in adolescents and young adults with developmental dysplasia of the hip. We have carried out a retrospective review of 51 hips after triple osteotomy with an average follow-up of ten years (8 to 15). Forty-eight hips (94%) were available for review and of these 39 (81%) were improved compared with before operation, 29 (60%) scoring good or excellent. Radiographic assessment showed improvement of the average centre-edge angle by 19°, the acetabular index by 12° and the anterior centre-edge angle by 26°. The degree of osteoarthritis progressed by one grade in ten hips (21%) over a period of ten years.

The satisfactory long-term clinical and radiographic results have encouraged us to continue this treatment for symptomatic acetabular dysplasia in these patients.
