- During a 13 year period, 286 patients with cervical disc herniation and/or spondylotic spurs, were subjected to anterior decompression and vertebral interbody fusion with autologous bone. Twenty patients were re-admitted in the late postoperative period due to recurrent radicular symptoms and/or signs of myelopathy. In these patients myelography was performed again. In 14 patients spinal cord compression and/or nerve root involvement at a new level was visualized. At the operated level, however, the myelograms demonstrated a smooth anterior wall in the spinal canal. The series confirms the safety, effectiveness and reliability of the Cloward procedure in achieving long term spinal cord and nerve root decompression, and a solid vertebral interbody fusion.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To analyse the outcome of selective management of patients with abdominal aortic aneurysms, the expansion patterns of the aneurysms, and the factors that influenced the rate of rupture. DESIGN: Retrospective study. SETTING: Malmo General Hospital, Lund University, Malmo, Sweden. SUBJECTS: 155 patients (96 men and 59 women) with abdominal aortic aneurysms who were not selected for operation for whatever reason were included in the study immediately after their first ultrasound scan. MAIN OUTCOME MEASURES: Mortality, expansion rate (mm/year) measured on ultrasound scan, and rate of rupture of aneurysm. RESULTS: Median aneurysmal diameter was 40 mm (range 20-80), and length (n = 106) 70 (range 28-140). The patients were followed up for a median of 3.4 years (range 0-10.2). A total of 107 patients died and in 21 the aneurysms ruptured (4 were operated on and survived). Thirteen patients were re-evaluated and operated on electively. Ultrasonography was repeated in 98 patients, the median expansion rates (mm/year) were 3.1 (diameter) and 1.9 (length). There was a significant linear relationship between initial size (diameter and length) and rate of expansion of diameter. The risk of rupture was greater in larger aneurysms that were expanding more quickly. The cumulative mortality was not affected by the 21 aneurysms that ruptured. CONCLUSION: Selective management of patients with aortic aneurysms is justified.

Silicone rubber implants for arthrosis of the scaphotrapezial joint
- 1992
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 26:2, s. 173-176

- Between 1980 and 1983, 10 patients received high performance silicone rubber condylar implants for the treatment of isolated degenerative changes of the scaphotrapezial joint. Early clinical and radiographic results (at a mean of 15 months) were excellent. Late follow up of these 10 together with a further 11 patients, however, showed migration of the implant and radiological signs of silicone particle synovitis in all but two. We no longer recommend this operation for treatment of isolated arthrosis of the scaphotrapezial joint.

Complications after transpedicular stabilization of the spine. A survivorship analysis of 163 cases
- 1994

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES. The authors studied complications of transpedicular stabilization methods. SUMMARY OF BACKGROUND DATA. One hundred and sixty-three consecutive transpedicular stabilization procedures were performed between January 1987 and December 1991. The indications for stabilization were trauma (33 cases), metastatic spinal disorder (30 cases), spinal stenosis (33 cases), spondylolisthesis (27 cases), ankylosing spondylitis (6 cases), low back pain (22 cases), and miscellaneous (12 cases). METHODS. Patients records and the entire series of radiographs for each case were scrutinized by independent observers. All per- and postoperative complications, including implant loosening and fatigue, were recorded. Clinical and radiographic survivorship analyses of the implants were performed. RESULTS. Early complications were unusual and none were associated with permanent morbidity. The probability of not having the implant removed in the first postoperative year was 85%. There was a 40% risk of radiographic failure, defined as loosening or implant fatigue, at 6 months. The outcome was more favorable in cases in which anterior vertebral interbody fusion was also performed. CONCLUSIONS. Transpedicular fixation is a safe procedure with a low incidence of serious per- and early postoperative complications. The mechanical durability of transpedicular fixators used alone is a cause for concern.

Individuals who sustain nonosteoporotic fractures continue to also sustain fragility fractures
- 1993
-
Ingår i: Calcified Tissue International. - 1432-0827. ; 53:4, s. 229-231
-
Tidskriftsartikel (refereegranskat)abstract
- This retrospective case control study was done in order to investigate whether patients who sustain a "nonosteoporotic fracture" early in life also continue to sustain fragility fractures later in life. All patients who had been treated at the Department of Orthopedics in Malmo with a tibial shaft fracture from 1949 to 1963 (n = 767) or an ankle fracture from 1961 to 1965 (n = 786) were included in this study. At the time of follow-up in 1992, 231 of the patients who sustained a tibial shaft fracture and 260 of the patients who sustained an ankle fracture were still living in the city of Malmo. Objective registration was done of all subsequent fractures that these former patients had sustained. Comparison was done with corresponding data from double numbers of age- and sex-matched controls who at that time (1950s and 1960s) had no such fractures. At the time of the fracture as well as today, the controls were living in the area of Malmo. Individuals with earlier tibial or ankle fractures had an increased incidence of fractures generally classified as fragility fractures. There was no difference in this respect between men and women, nor whether the initial fracture had been diaphyseal or metaphyseal. We conclude that sustenance of fractures early in life may serve as a predictor for fragility fractures later in life.

Periarticular bone in rheumatoid arthritis versus arthrosis. Histomorphometry in 103 hip biopsies
- 1994
-
Ingår i: Acta Orthopaedica Scandinavica. - : Medical Journals Sweden AB. - 0001-6470. ; 65:2, s. 135-138
-
Tidskriftsartikel (refereegranskat)abstract
- Histomorphologic differences of the periarticular bone in rheumatoid arthritis (RA) and osteoarthrosis (OA) may be of importance for long-term prosthetic fixation. We have evaluated bone specimens, obtained during total hip replacement from an acetabular and a femoral biopsy site, in 42 RA-hips and 61 OA-hips. In both groups the bone turnover was increased in the acetabulum compared to that in the femur. In the acetabulums the total trabecular bone volume was equal, but osteoid volume, osteoid surface, resorptive surface, and the appositional rate were increased in RA. On the femoral side, only the osteoid volume was higher in RA. The increased bone turnover with a greater amount of unmineralized tissue, as well as resorptive activity in the acetabulum, may be of importance for the higher rate of acetabular component migration and loosening after total hip replacement in RA.

Periarticular bone mineral content in rheumatoid arthritis and arthrosis of the hip. Dual photon X-ray absorptiometry in 53 cases
- 1993
-

Tidskriftsartikel (refereegranskat)abstract
- The bone mineral content (BMC) was determined by dual photon X-ray absorptiometry prior to hip replacement in 22 patients with rheumatoid arthritis and 31 with arthrosis. Compared with the arthrosis patients, the rheumatoids had approximately 20 percent lower bone mineral content in the proximal femur, the lumbar spine, and in the innominate bone superior to the acetabulum.

Differences in fracture pattern between an urban and a rural population: a comparative population-based study in southern Sweden
- 1992
-
Ingår i: Osteoporosis International. - 1433-2965. ; 2:6, s. 269-273
-
Tidskriftsartikel (refereegranskat)abstract
- Differences in the incidence of hip fractures have been reported between urban and rural areas. In this population-based study the characteristics of fracture patterns between the city of Malmo and the nearby rural district of Sjobo were compared. A total of 782 individuals in Malmo and 486 in Sjobo were invited to participate. Fracture history for all invited was registered. The odds ratio for fracture was higher in Malmo, particularly for women over 70. More than half of the urban women aged 70 had a history of a fracture. A fourfold increase in fracture prevalence between the ages of 60 and 70 was observed in women in Malmo, whereas the prevalence doubled in Sjobo. The differences in fracture patterns between these two urban and rural communities may be explained by different lifestyles.
