Post-traumatic partial rupture of the extensor carpi ulnaris tendon. Case report.

A 40 year old man presented with continued pain, tenderness and slight swelling on the ulnar aspect of his right wrist after handling a heavy object. At operation, partial rupture of the extensor carpi ulnaris tendon was diagnosed and successfully treated by suture of the tendon. Partial rupture of the extensor carpi ulnaris tendon may be more frequent than previously reported, and the diagnosis should be considered in patients with symptoms of post-traumatic synovitis of the tendon.

[Emergency services in the admission department of a central hospital].

Medical treatment during the evening and night hours has been the subject of debate at present on account of changes in the practitioner-on-call system. The emergency medical service in the catchment region for the Central Hospital in Naestved before these changes was therefore analysed. Services rendered in this region outside working hours, both by the physician-on-call and the hospital, were registered for the period 1.12.1989-31.1.1990. A total of 8,742 consultations occurred during the period, viz every tenth member of the population sought medical advice. The majority of these contacts were with the practitioner-on-call as 7,253 (83%) sought their general practitioner first and the remainder came to hospital. This corresponds to 117 consultations with the practitioner-on-call and 22 visits to the casualty department per 24 hours of emergency service. Among the patients seeking help from the casualty department, it was found that 30% could have been treated in general practice. Among the taks for the practitioner-on-call, there were 27% telephone consultations, 21% in practice and 52% home visits. No differences were observed between urban rural regions as regards the proportions of services but the number of services followed population percentages. 11% sought medical help at night and 1/3 of these patients were referred to hospital. In the present material, there appeared to be relatively great misuse of the telephone number 000 (equivalent to 999) as only 1/3 of these patients were admitted to hospital. A total of 1,263 patients were admitted to hospital and 78% (982) of these had been seen primarily by the practitioner-on-call.(ABSTRACT TRUNCATED AT 250 WORDS)

[Commercially available substitutes for transplants of human bone].

As alternative or supplements to transplantation of human bone in cases of bone defects or reconstructions of bones, a series of commercially available materials exist. Kieler bones, which are made from bovine bones are the oldest preparation. Kieler bones consist of up to 30% protein. This gives the bone elasticity but may also involve immunogenic reactions to the implant. Calcium phosphate, in the form of synthetic or semi-synthetic hydroxyapatite or hydroxyapatite/tricalcium phosphate, is, on the other hand, quite inelastic which makes these implants unsuitable in regions with mechanical stress. Proplast consists of carbon fibres coated with Teflon and may be employed for subperiostal reconstructions. BOP is a new system of synthetic materials built up from polyamide fibres and/or absorbable matrix. This system combines mechanical strength with ingrowth of bone but, as yet, experience with this material is only limited. Commercial substitutes for human bones should only be employed on limited indications and taking the mechanical properties of the implants and the capacity for substitution with regenerating bony tissue into consideration.

[Removal and storage of human bone for transplantation. Directives for infection control].

When bone is transplanted from one person to another, a risk of simultaneous transfer of infectious material is present. Transfer of bacteria is commonest but transmission of Hepatitis virus and HIV have been described. In order to reduce this risk as much as possible, medical and social screening of the donors are recommended together with hepatitis B antigen test (HBsAg), hepatitis C antibody test (anti-HCV) and HIV antibody test. In addition, living donors are preferable on account of the better possibilities for screening. The risk of transfer of HIV is limited at present, if male donors are aged over 60 years and female donors are over 40 years. Removal of the tissue should always be undertaken under sterile conditions. Aerobic and anaerobic culture of multiple bone biopsies from the transplant on removal of the tissue are recommended. Neither freezing nor freeze-drying result in decontamination of the bone. Chemical methods and also irradiation are considered inadequate or injurious to the quality of the bone.

[Ambulatory orthopedic surgery].

A one year survey of the patients assessment of out-patient orthopaedic surgery in local anaesthesia is presented. The report is based upon questionnaires (including 15 items) of 529 operations performed on 495 patients. A large group of knee arthroscopies are included. We found that many orthopaedic operations, formerly treated as in-patient procedures could be carried out in the out-patient clinic with only a minimal complication rate. 77% of the patients experienced no problems other than pain in their home following the out-patient surgical procedure. Nearly 80% of the patients would choose out-patient surgery in case of a new identical operation. 30% of the patients found the administration of the local anaesthesia very painful and 41% experienced discomfort and pain following surgery. In addition, a brief analysis of the economical aspect is given. In conclusion, out-patient orthopaedic surgery is well accepted by the patients. The use of local anesthesia alone is not always sufficient and administration of an oral analgesic drug both before and after the surgical procedure is recommended.

Chronic retrocalcaneal bursitis treated by resection of the calcaneus.

Resection of the posterosuperior aspect of the calcaneus was performed on 43 heels, in 35 patients with chronic retrocalcaneal bursitis. Forty heels in 32 patients were reviewed either by a clinical and radiographical examination (35 heels), or by a questionnaire (5 heels) after an average of 6 years (range 1-12 years). Fifty percent of the heels were cured and additionally 20% improved, but when surgery was performed within 1 year, 92% of the heels were either cured or improved. No correlation was found between the result of surgery and the estimated size of the resection made at surgery.

Fibrin fixation of osteochondral talar fracture.

Six osteochondral talar fractures in 5 patients were fixed with fibrin sealant. All the lesions healed uneventfully. After 1 year, 3 of the 4 athletes in the study had resumed their sports activities at the same level as prior to the accident.

Association of ankle instability and foot deformity.

95 patients operated on for chronic lateral ankle instability were compared for possible foot deformities with 34 normal persons. All the feet underwent a standardized radiographic examination. Measurements of three defined angles on a lateral nonweight-bearing radiograph indicated higher foot arches in the instability group than in the control group. Benink's tarsal index showed a higher frequency of cavovarus deformities in the instability group.

Functional results following fractures of the proximal humerus. A controlled clinical study comparing two periods of immobilization.

In order to compare 1 and 3 weeks of immobilization following proximal humeral fractures a prospective controlled trial was performed in 85 patients. Clinical follow-up according to the Neer assessment system was done after 1, 3, 6, 12, and 24 months. One week of immobilization resulted in a better total score due to less pain during the first 3 months. After 6 months no difference in pain, function, or mobility was found and no further recovery of shoulder function was seen after 12 and 24 months.

Osteochondritis dissecans of the talus: long-term results of surgical treatment.

Twenty patients with osteochondritis dissecans of the ankle were reviewed for a clinical and radiographical follow-up 9 to 15 years after surgery including multiple drilling of the lesion combined with excision of loose fragments. The short-term results of surgery were satisfactory: 85 degrees of the patients were improved or cured. At follow-up, more than half of the patients had some degree of pain during activity, and swelling of the ankle, but only a few had locking or pain at rest. Only one of the 18 patients without osteoarthritis at the time of surgery had developed generalized osteoarthritis at the follow-up. Although the initial good results of surgery were demonstrated to deteriorate with time, the procedure can still be recommended in patients with longstanding symptoms.
