A special high tibial osteotomy technique for treatment of unicompartmental osteoarthritis of the knee.

Tibial osteotomy is a well-established procedure for treatment of the varus osteoarthritic knee. A special new technique of oblique tibial osteotomy at the level of the tibial tubercle, preserving the medical cortex and iliotibial band, is presented which allows partial weight bearing the first postoperative day. Postoperatively the femorotibial alignment should be 5 degrees to 7 degrees of valgus in elderly patients. Because in younger individuals the intact iliotibial band is a strong restraint against varus deformity, we seek to correct to 3 degrees to 5 degrees of valgus in these patients. Of 172 cases treated with this technique between 1982 and 1986, 50 patients were retrospectively reviewed. After a follow-up period of 6 months to 3 years, pain was relieved in 46 patients. Complications consisted of 5 secondary wound healings, including 2 superficial infections, 1 tibial plateau fracture, and 3 varus recurrences.

[Arthroscopic revision of the sub-acromial space in impingement syndrome].

Degenerative lesions of the subacromial structures can cause chronic anterior pain and disability of the shoulder. They are most frequently found in patients whose arms are repeatedly exposed to force while raised above head level, e.g. during tennis, volleyball or swimming. This is often due to impingement of the supraspinatus tendon, the subacromial bursa or the biceps tendon against the anterior edge and lower surface of the anterior third of the acromion, the coracoacromial ligament and, in some cases, the acromioclavicular joint. Open anterior acromioplasty as described by Neer is therefore a well-documented treatment for cases refractory to conservative therapy, and its efficacy is unquestioned. Acromioplasty or simple decompression by débridement can now be performed by means of basic arthroscopic techniques. Subacromial decompression is carried out with standard arthroscopic approaches and motorized instruments. The indications are about the same as for the open technique, and the three progression stags of impingement lesions must also be considered in the same way. Arthroscopic decompression was performed in 13 patients with a chronic impingement syndrome that had failed to respond to conservative management over 6 months. All underwent a débridement of the subacromial bursa, 11 shaving of a partial tear of the rotator cuff, and 8 anterior acromioplasty; in 5 patients spurs arising from the acromion or the acromioclavicular joint were also removed. In 2 cases the coracoacromial ligament was released and in 3 patients calcareous deposits were needled. In most cases these procedures were combined. The patients were evaluated postoperatively with reference to the UCLA Shoulder Rating Scale with a follow-up of 12-18 months, particular attention being paid to pain and function.(ABSTRACT TRUNCATED AT 250 WORDS)

[Evaluation of scintigraphic procedures for clarifying pain conditions in hip joint prostheses].

59 patients with implanted one- or two-sided hip prostheses (n = 74) have been investigated by two different scanning techniques to detect both possible loosening of the prostheses and a possible infection as the cause of the loosening. Of the investigated prostheses 47 were loose; in 45 cases this was evidenced by the bone scan using Tc-99m-DPD, thus showing a sensitivity of 95%. Specificity was 89%. In 21 cases (45%) of loose prostheses an infection could be clinically proven. With the aid of In-111 labeled leukocyte scans, 17 of 21 cases were correctly diagnosed as infected, showing a sensitivity of 91%, while the specificity was 94%. In view of the 93% accuracy, bone scanning can be regarded as the method of choice in detecting loosening of prostheses. The 91% accuracy in proving or ruling out infection by means of the leukocyte scan is high enough to assert correct findings in most cases. The main disadvantage of this method is the very demanding technique for marking of white blood cells.
