- We have reviewed 20 women and three men aged 22 to 73 years, who had sustained a Mason type-lib fracture of the neck of the radius 14 to 25 years earlier. There were 19 patients with displacement of the fractures of 2 mm to 4 mm, of whom 13 had been subjected to early mobilisation and six had been treated in plaster for one to four weeks. Of four patients with displacement of 4 mm to 8 mm, three had undergone excision and one an open reduction of the head of radius. A total of 21 patients had no subjective complaints at follow-up, but two had slight impairment and occasional elbow pain. The mean range of movement and strength of the elbow were not impaired. The elbows had a higher prevalence of degenerative changes than the opposite side, but no greater reduction of joint space. Mason type-lib fractures have an excellent long-term outcome if operation is undertaken when the displacement of the fracture exceeds 4 mm.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Popliteal artery injury (PAI) is a feared but rare complication during knee arthroplasty (KA). The aim was to study PAI during KA: Type of injury, treatment and outcome.Thirty-two cases were identified in the national Swedish vascular registry (Swedvasc) and the Swedish Patient Insurance databases. Prospective data from the registries was supplemented with case-records, including long-term follow-up.Twenty-five injuries (78%) were due to penetrating, seven to blunt trauma. Three different presentations of injury were identified: Bleeding (n=14), ischaemia (n=7) and false aneurysm formation (n=11). Five (16%) cases were during revision KA. Twelve injuries (38%) were detected intraoperatively, eight (25%) within 24 hours (range 3-24) and twelve (38%) >24 hours postoperatively (range 2-90), 28 (88%) were treated with open surgery. Patency at 30 days was 97% (one amputation). Twenty-five (78%) patients had residual symptoms at the end of follow-up (median 546 days, range: 24-1251). Six of the seven patients with complete recovery had an early diagnosis of the PAI during the procedure, and were treated by a vascular surgeon in the same hospital.Outcome after popliteal artery injury during KA is often negatively affected by diagnostic and therapeutic delay. Bleeding and pseudoaneurysm were the most common clinical presentations.

Deep-seated ordinary and atypical lipomas - Histopathology, cytogenetics, clinical features, and outcome in 215 tumours of the extremity and trunk wall

- Deep-seated lipomas are often atypical histologically and are considered by some to have a high risk of recurrence after excision. We reviewed 215 deep-seated lipomas of the extremities and trunk wall with reference to histology, cytogenetics, clinical features and local recurrence. We classified tumours with atypical features and/or ring chromosomes as atypical lipomas. These were more common in men, larger than ordinary lipomas and more often located in the upper leg. The annual incidence was estimated as ten per million inhabitants and the ratio of atypical to ordinary lipomas was 1:3. In total, six tumours (3%), recurred locally after a median of eight years (1 to 16); of these, four were classified as atypical. The low recurrence rate of deep-seated lipomas of the extremity or trunk wall, irrespective of histological subtype, implies that if surgery is indicated, the tumour may be shelled out, that atypical lipomas in these locations do not deserve the designation well-differentiated liposarcoma, and that routine review after surgery is not required.

- Background:The risk of revision surgery following total joint arthroplasty (TJA) may be influenced by genetic factors. Therefore, we sought to identify genetic variants associated with the risk of revision surgery in a genomewide association studyMethodsWe investigated a cohort of 1,130 twins from the Swedish Twin Registry treated with TJA. During a mean of 9.4 years of follow-up, 75 individuals underwent revision surgery for aseptic loosening (the primary outcome) and 94, for any reason (the secondary outcome). Genetic information was collected using the Illumina OmniExpress and PsychArray panels, and the Haplotype Reference Consortium served as the reference for gene imputation. Adjusted Cox regression models were fitted to calculate hazard ratios (HRs) with 95% confidence intervals (CIs).ResultsNine single-nucleotide polymorphisms (SNPs) reached genomewide significance for aseptic loosening. The first SNP, rs77149046, located in the endosome-lysosome associated apoptosis and autophagy regulator family member 2 (ELAPOR2) gene, conferred an HR of 5.40 (CI, 3.23-9.02; p = 1.32×10−10), followed by 4 SNPs within the region coding for sodium-dependent taurine and beta-alanine transporter (SLC6A6), with HRs ranging from 3.35 to 3.43. The sixth SNP, rs7853989 (HR, 3.46; CI, 2.33-5.13; p = 6.91×10−10), was located in a region coding for the ABO blood group system. This SNP has been described as predictive for blood type B. Seven significant SNPs were found for the risk of revision for any reason, with the first 4 again being located in the SLC6A6 region. The leading SNP, rs62233562, conferred an HR of 3.11 (CI, 2.19-4.40; p = 1.74×10−10) for revision surgery. Similar HRs were found for SNPs 3:14506680 (p = 1.78×10−10), rs2289129 (p = 1.78×10−10), and rs17309567 (p = 3.16×10−10). The fifth SNP, rs11120968, was located in the calmodulin-binding transcription activator 1 (CAMTA1) gene (HR, 2.34; CI, 1.74-3.13, p = 1.45×10−8).ConclusionsWe identified 12 unique SNPs associated with an increased risk of revision surgery. Among these, 2 were in ELAPOR2, which is closely linked to bone formation. Another SNP is located in a gene region encoding for the ABO system, which merits further studies of causal relationships.

Appropriate questionnaires for knee arthroplasty. Results of a survey of 3600 patients from The Swedish Knee Arthroplasty Registry
- 2001

Tidskriftsartikel (refereegranskat)abstract
- The Swedish Knee Arthroplasty Registry (SKAR) has recorded knee arthroplasties prospectively in Sweden since 1975. The only outcome measure available to date has been revision status. While questionnaires on health outcome may function as more comprehensive endpoints, it is unclear which are the most appropriate. We tested various outcome questionnaires in order to determine which is the best for patients who have had knee arthroplasty as applied in a cross-sectional, discriminative, postal survey. Four general health questionnaires (NHP, SF-12, SF-36 and SIP) and three disease/site-specific questionnaires (Lequesne, Oxford-12, and WOMAC) were tested on 3600 patients randomly selected from the SKAR. Differences were found between questionnaires in response rate, time required for completion, the need for assistance, the efficiency of completion, the validity of the content and the reliability. The mean overall ranks for each questionnaire were generated. The SF-12 ranked the best for the general health, and the Oxford-12 for the disease/site-specific questionnaires. These two questionnaires could therefore be recommended as the most appropriate for use with a large knee arthroplasty database in a cross-sectional population.

- We analysed the axis of movement in the normal elbow during flexion in vivo using radiostereometric analysis (RSA). The results show an intraindividual variation in the inclination of the axis ranging from 2.1° to 14.3° in the frontal and from 1.6° to 9.8° in the horizontal plane analysed at 30° increments. The inclination of the mean axis of rotation varied within a range of 12.7° in the frontal and 4.6° in the horizontal plane. In both planes, the mean axes were located close to a line joining the centres of the trochlea and capitellum. The intra- and interindividual variations of the axes of flexion of the elbow were greater than previously reported. These factors should be considered in the development of elbow prostheses.
