- Lack of an agreed infrastructure for terminology is identified as one of the major barriers to interchange of knowledge modules and integration of knowledge bases with other clinical information systems. The goal of the GALEN project is to bridge this gap between different terminology systems through the construction of a terminology server, which is based on a rich conceptual model with mapping facilities to natural language expressions and coding schemas. The long term goal is to support communication between medical information systems. Arden Syntax is a standard format for the creation of knowledge modules, with sharability as one of the main objectives. Since Arden Syntax is based on a data-driven approach, the data items used need to be adapted to locally available terminology. The GALEN approach appears to be complementary to Arden Syntax and to the development of sharable knowledge modules. The major theme of this paper is utilization of the GALEN terminology server for knowledge module authoring. Two systems are presented, a knowledge base manager and a client to the terminology server, allowing the user to navigate in the semantic network and to import concept definitions and terms into the knowledge modules. The benefit of the terminology services is discussed.

- The aim of this study was to investigate health and disability in people with acute traumatic hand injury 10 years after the accident. A consecutive sample of patients from the Department of Hand Surgery was followed up by means of a postal questionnaire containing the instruments EQ-5D for assessment of health and DASH for assessment of disability. Questions were added about cold sensitivity, numbness and aesthetic problems. The 97 people with various acute hand injuries had greater problems with impairments of hand function than with limitations of activities and participation in daily life. Pain was more common than among the general Swedish population. Cold sensitivity was reported by 78% and was associated with both worse impairments and greater limitations on activity and participation. Despite problems with pain and cold sensitivity, they reported good health and a low degree of disability.

- The aim of this study was to obtain a better understanding of the cause of the medial rotation contracture of the shoulder after obstetric brachial plexus lesions by studying the morphology of the shortened subscapularis muscle. Muscle biopsy specimens were harvested from 13 children with obstetric brachial plexus palsy who underwent corrective surgery for the rotation contracture. The majority of the subscapularis muscle biopsy samples had an essentially normal morphology and showed a predominance of type I myosin heavy chain isoform, while one biopsy showed signs of marked fibrosis and a predominance of type II myosin heavy chain isoform. The findings support the assumption that shortening of the subscapularis is caused primarily by the nerve injury, which weakens the antagonistic lateral rotators, but that direct injury to the muscle might be a contributory factor.

Radioulnar laxity and clinical outcome after a distal radius fracture do not correlate after a distal radius fracture
- 2011

- Injury to the triangular fibrocartilage complex associated with distal radius fracture may cause symptoms of ulnar instability. Assessed by a radioulnar stress test, increased laxity of the distal radio-ulnar joint has in two previous studies been depicted to be associated with poorer outcome. This prospective study of 40 adults investigates the correlation of this test with functional outcome as measured by DASH. No clinically significant difference was found in relation to this test at two and five years after injury. Therefore using this test alone to decide whether or not to perform an acute repair of the TFCC cannot be recommended.

- Many strategies have been investigated to provide an ideal substitute to treat a nerve gap injury. Initially, silicone conduits were used and more recently conduits fabricated from natural materials such as poly-3-hydroxybutyrate (PHB) showed good results but still have their limitations. Surgically, a new concept optimising harvested autologous nerve graft has been introduced as the single fascicle method. It has been shown that a single fascicle repair of nerve grafting is successful. We investigated a new approach using a PHB strip seeded with Schwann cells to mimic a small nerve fascicle. Schwann cells were attached to the PHB strip using diluted fibrin glue and used to bridge a 10-mm sciatic nerve gap in rats. Comparison was made with a group using conventional PHB conduit tubes filled with Schwann cells and fibrin glue. After 2 weeks, the nerve samples were harvested and investigated for axonal and Schwann cell markers. PGP9.5 immunohistochemistry showed a superior nerve regeneration distance in the PHB strip group versus the PHB tube group (> 10 mm, crossed versus 3.17+/- 0.32 mm respectively, P<0.05) as well as superior Schwann cell intrusion (S100 staining) from proximal (> 10 mm, crossed versus 3.40+/- 0.36 mm, P<0.01) and distal (> 10 mm, crossed versus 2.91+/- 0.31 mm, P<0.001) ends. These findings suggest a significant advantage of a strip in rapidly connecting a nerve gap lesion and imply that single fascicle nerve grafting is advantageous for nerve repair in rats.

- Reconstruction of grip in tetraplegia aims to improve upper extremity performance and control in daily life. We evaluated the effects of surgery and rehabilitation on performance and satisfaction of patient identified activity goals in 20 patients (22 arms) who had grip reconstructions for both finger and thumb flexion. Patients assessed an improvement in both performance and satisfaction after surgery in all groups of activities assessed using the Canadian Occupational Performance Measure (COPM). The mean improvement at 6 and 12 months was 3.5 points better than the 2.5 points before surgery. Before surgery 36% of the goals identified were impossible to perform. After surgery, 78% of these goals were possible. The largest improvement was observed in the basic activity of 'eating' but significant improvement was also noted in activities generally regarded as complex and not measured in standard ADL such as 'doing housework' and taking part in 'leisure'.

- Fracture dislocations of the PIP joint are challenging to treat. In hemi-hamate arthroplasty, the palmar lip joint surface is reconstructed using an osteochondral graft from the hamate and the immediate stability permits early movement. In the long term, collapse of non-vascularized osteochondral grafts might lead to degenerative arthritis. We examined the radiographic result after a minimum of 4 years with special reference to the development of osteoarthritis and its relation to clinical symptoms in eight patients, mean age 49 (25-66) years. After a mean of 60 (48-69) months, the arc of motion was 67 degrees (45 degrees -95 degrees ) at the PIP joint and grip strength was 91% of the uninjured side. The visual analogue score for pain (0-100) was 10 (0-70) mm. Severe arthritis (grade IV) was found in two and mild arthritis (grade II) in another two patients, but only one of these four cases had troublesome pain. The hemi-hamate technique is an attractive alternative to other treatment options, but some cases develop osteoarthritis in the medium term.

- We investigated the difference between postoperative rehabilitation with or without adjunctive intermittent pneumatic compression therapy following distal radial fracture treated with volar plating. A total of 115 patients were randomized to a control or to an experimental group. After 4 weeks of immobilization the experimental group received intermittent pneumatic compression therapy in addition to conventional postoperative rehabilitation. Primary outcome up to 1 year postoperatively was assessed using the Canadian Occupational Performance Measure. No significant differences between groups were found. There were no clinically relevant differences regarding the secondary outcome measures swelling, strength, pain and flexibility. We conclude that postoperative intermittent pneumatic compression treatment had no major benefits. The results of the present study do not support general use of intermittent pneumatic compression initiated 4 weeks following volar plating surgery for distal radial fracture. Level of evidence: I

Tidskriftsartikel (refereegranskat)abstract
- We studied self-concept and psychological well-being in children with hand deformities and upper limb deficiencies. Ninety-two children, 53 boys, 39 girls, aged 9-11 years were included. The children were divided into two subgroups - one with milder (less visible) deformities and one with severe (more complex and visible) finger-hand-arm deformities. Of the 92 children, 79 had received reconstructive surgery, and 13 had been treated with prostheses. The Piers-Harris Children's Self-Concept Scale (PHCSCS) was used to measure self-esteem and well-being. Overall PHCSCS scores showed that the whole hand deformity group had 'good' self-concept with mean scores in excess of 60 points, equal to a comparison group of healthy children. Within the hand deformity group, those with mild deformities had lower scores than those with severe deformities. This result was also found in the group of boys but not in the girls. The children with severe deformities had even higher scores than the comparison group regarding the subscale 'Intellectual and School Status'. The children with milder deformities had lower scores than the comparison group regarding the subscale 'Popularity'.
