    Description / Table of Contents: Summary The distal metatarsal osteotomy according to Magerl allows correction of a hallux valgus deformity by lateral and plantar displacement as well as by pronation and varisation. The length of the first metatarsal can be adjusted by the depth of the cut at the resection or by a slightly oblique osteotomy. If necessary, soft tissue release and/or a osteotomy of the first proximal phalanx can be done to relocate the sesamoids under the head of the first metatarsal. A review of 118 foot operations in 75 patients demonstrated a very good or good result in about 75 %. Radiological examination showed sufficient lateralisation of the metatarsal head. Evaluating the length of the first metatarsal and the amount of variation, the results were less satisfying. The metatarsophalangeal angles could be corrected by 14 ° and the intermetatarsal angles by 7 ° on average. The sophisticated operative procedure limits the use of this technique as a standard procedure.
    Notes: Zusammenfassung Die subkapitale Osteotomie nach Magerl erlaubt eine Korrektur des Hallux valgus, indem das Köpfchen lateralisiert, varisiert, rotiert und plantarisiert wird, und bei der auch die Länge des Os metatarsale I durch die Tiefe des plantaren Einschnitts bzw. durch eine schräge Osteotomieebene beeinflußt werden kann. Falls notwendig, kann durch einen gleichzeitigen Weichteileingriff zusätzlich eine Rezentrierung der Sesambeine unter das Köpfchen des Os metatarsale erzielt und damit auch der Streckapparat rezentriert werden. Die Korrektur einer Phalanx proximalis I valga ist in gleicher Sitzung korrigierbar. Die Auswertung von 118 operierten Füßen bei 73 Patienten zeigte in ca. 75 % ein sehr gutes bzw. gutes klinisches Ergebnis. Die radiologische Auswertung zeigte eine zufriedenstellende Lateralisierung, weniger zufriedenstellend waren die Ergebnisse im Hinblick auf die Länge des Os metatarsale I und das Ausmaß der Varisation. Der Hallux-valgus-Winkel konnte um durchschnittlich 14 ° und der Intermetatarsalwinkel um 7 ° korrigiert werden. Die hohen technischen Anforderungen dieser Osteotomie schränken jedoch ihre Anwendbarkeit als Routineverfahren ein.

    Aseptic loosening of straight-and curved-stem Müller femoral prostheses (1991)
    Springer
    Archives of orthopaedic and trauma surgery 110 (1991), S. 190-194

    Notes: Summary Out of 1099 Müller total hip prostheses with straight and curved stems consecutively implanted between 1980 and 1984, those performed in as homogeneous a group as possible of patients under the age of 70 years were selected for the present retrospective study. There were 158 straight femoral stems with cementless RM acetabular cups, 105 straight stems with cemented Müller acetabular cups, and 158 curved stems with cemented Müller acetabular cups, and their results over a mean follow-up period of 5.8 ± 1.24 years were compared. Six (3.7%) curved and 5 (1.9%) straight-stem prostheses were exchanged due to aseptic loosening; 26 (16.3%) curved and 54 (20.1%) straight-stem prostheses were “at risk” or loose at the time of follow-up. Survival curves show a worse result for straight stems after 6 years; within a follow-up period of 6–8 years there was significantly more radiological loosening in straight stems than in curved. Loosening in straight stems is assumed to develop mainly as a physiological reaction to the presence of bone cement particles.

    Surgical treatment of neuropathic scoliosis: morphologic and functional outcome (1997)
    Springer

    Details

    Topics: Medicine
    Notes: Abstract We evaluated the morphologic and functional outcome as well as the extent of satisfaction following surgical treatment in 41 patients with progressive neuropathic scoliosis. The mean follow-up time was 5.6 years (range 2.5–20 years), and follow-up rate was 97.6%. Posterior spine fusion was performed with new instrumentation techniques (Luque/Luque-Galveston, CD, ISOLA) in 29 patients, with extension onto the sacrum in 16 patients, and Harrington instrumentation in 12. In 20 patients we did an additional intervertebral disc excision and fusion. Mean correction of the thoracic spine deformity, as assessed by comparing the Cobb angles on pre- and postoperative X-rays, was 53%, and of the lumbar spine 55.2%, in patients classified as Lonstein I. Scolioses classified as Lonstein II evidenced an average correction of 46.2%. Functional improvement according to the Rancho-Los Amigos scheme could be demonstrated in 20 patients. Seventeen patients remained unchanged, whereas 4 patients showed deterioration. Cosmetic results were rated as excellent by 25 patients, good by 7, and poor by 1. For 8 patients the appearance was unimportant. Pain relief was experienced in all cases (n = 4) of the preoperative low-back or abdominal pain. The major complications were deep wound infection in 3 patients which led to revision surgery, and removal of instrumentation in I patient.

    Uncoated polyethylene RM acetabular component versus Müller cemented acetabular component A 4- to 8-year follow-up study (1991)

    Notes: Summary Comparable patient populations with 160 uncoated RM acetabular cups and 263 cemented Müller standard acetabular cups were submitted to survivaltime analysis in a retrospective study with a mean followup of 5.3 years for the RM cup and 6.1 years for the Müller cup. After 7–8 years 12% of the RM cups and 4% of the Müller cups had been exchanged, 40% and 15% respectively were loose. The poor performance of the RM cups is ascribed to additional external polyethylene wear, which leads to the formation of granulomas and destroys the weight-bearing osseous structures. Similar granulomas also develop on the proximal stem and thus endanger the same.

    Acetabular development following early treatment of hip dysplasia by Pavlik harness (1994)

    Notes: Abstract One hundred sixty-two neonates with sonographically diagnosed developmental dysplasia of the hip (200 hips) according to the method of Graf were treated with a Pavlik harness until sonographic maturation was reached. Eight patients (12 hips) treated with closed reduction and retention in a bilateral hip spica cast were included. When the children started to walk their acetabular indices were assessed and demonstrated low-grade dysplasia in 26% and high-grade dysplasia in 6% according to the criteria of Tönnis and Brunken. We discuss the current sonographic criteria defining treatment-induced normalization and the adequacy of the length of treatment. We conclude that despite normal values at the end of treatment dysplasia may develop, which necessitates further radiological monitoring of all hips initially rated at risk on sonography. When to end monitoring, however, remains to be determined.

    Description / Table of Contents: Summary Sixty-eight patients with idiopathic scoliosis who had undergone Harrington instrumentation at least 10 years previously (mean follow-up 14 years) were asked to return to our hospital for review. History and clinical examination were performed in 49 individuals (72%), radiographs in 44 individuals (64%). Pain was evaluated by means of the Dallas Pain Questionnaire and pain drawings according to Ransford. Segmental range of motion according to Begg and Falconer as well as sagitial translational motion measured according to Wiltse and Winter and to Morgan and King were evaluated in flexion/extension radiographs. Pain depended on fusion level. It occurred in 80% of those in whom fusion was carried down to L4 or lower vertebrae. There was no relationship between fusion level or pain on the one hand and segmental range of motion or increased translation on the other hand, and none between lordosis, pain and increased translation. Increased sagittal translocational motion of more than the measurement error of 5 mm does not seem to be an important cause of pain in individuals in whom Harrington instrumentation was carried down to low vertebral levels.
    Notes: Résumé 68 patients présentant une scoliose idiopathique et traités depuis au moins dix ans par l'instrumentation de Harrington (délai postopératoire moyen: 14 ans) ont été convoqués pour un examen de contrôle. 49 sujets (72%) ont eu un interrogatoire et un examen clinique et 44 (64%) un contrôle radiographique. La douleur a été évaluée à l'aide du questionnaire de la douleur de Dallas et des représentations graphiques de la douleur selon Ransford. L'amplitude de la mobilité segmentaire selon Begg/Falconer ainsi que la translation sagittale mesurée selon Wiltse/Winter et Morgan/King ont été évaluées sur des clichés dynamiques en flexion/extension. La douleur a été retrouvée, dépendant du niveau de fusion. Si la fusion a été étendue vers le bas au niveau ou au dessous de L4, la douleur est apparue dans 80% des cas. Il n'y avait pas de relation entre d'une part le niveau de la fusion ou la douleur et d'autre part l'amplitude du mouvement segmentaire ou l'accroissement de la translation; il n'y avait pas non plus de relation entre la lordose, la douleur et l'excès de translation. Une translation sagittale accrue, supérieure à l'erreur de mesure de 5 mm, ne semble pas être une cause importante de douleur chez des individus chez qui l'instrumentation de Harrington a été descendue jusqu'aux niveaux vertébraux inférieurs.
