    ABSTRACT: Articular cartilage has very limited intrinsic healing capacity. Although numerous attempts to repair full-thickness articular cartilage defects have been conducted, no methods have successfully regenerated long-lasting hyaline cartilage. One of the most promising procedures for cartilage repair is tissue engineering accompanied by gene therapy. With gene therapy, genes encoding for therapeutic growth factors can be expressed at a high level in the injured site for an extended period of time. Chondrocytes have been intensively studied for cell transplantation in articular cartilage defects. However, recent studies have shown that chondrocytes are not the only candidate for cartilage repair. Muscle-derived cells have been found capable of delivering genes and represent a good vehicle to deliver therapeutic genes to improve cartilage repair. More importantly, recent studies have suggested the presence of pluripotent stem cells in muscle-derived cells. New techniques of cell therapy and molecular medicine for the treatment of cartilage lesions are currently undergoing clinical trials. This paper will summarize the current status of gene therapy for cartilage repair and its future application.

    ABSTRACT: The treatment of acute of Achilles tendon rupture experienced a dynamic development in the last 10 years. Decisive for this development was the application of MRI and above all the ultrasonography in the diagnostics of the pathological changes and injuries of tendons. The question of rupture morphology as well as different courses of healing could be now evaluated objectively. These advances led consequently to new modalities in treatment concepts and rehabilitation protocols. The decisive input for improvements of the outcome results and particularly the shortening of the rehabilitation period came with introduction of the early functional treatment in contrast to immobilizing plaster treatment. In a prospective randomized study (1987-1989) at the Trauma Dept. of the Hannover Medical School could show no statistical differences comparing functional non-operative with functional operative therapy with a special therapy boot (Variostabil/ Adidas). The crucial criteria for therapy selection results from the sonografically measured position of the tendon stumps in plantar flexion (20°). With complete adaptation of the tendons ends surgical treatment does not achieve better results than non-operative functional treatment in term of tendon healing and functional outcome. Regarding the current therapeutic standards each method has its advantages and disadvantages. Both, the operative and non-operative functional treatment enable a stable tendon healing with a low risk of rerupture (1-2%). Meanwhile there is consensus for early functional aftertreatment of the operated Achilles' tendons. There seems to be a trend towards non-operative functional treatment in cases of adequate sonografical findings, or to minimal invasive surgical techniques.

    ABSTRACT: The aim of this study was to find out the reliability of several dermatomic maps (description of pain pattern within a nerve root lesion) according to the respective segmental area. Different studies which deal with pain pattern caused by disc lesions were searched for with MedLine support and then reviewed. A clear correlation between the pain projections of the lumbar spine does not seem to exist. A contradiction of the most common pain projection (S1) and operated disc (L4/5) is described. Even though there are studies of high scientific design and value (Nitta H, Wolff A) the pain pattern of dermatomic maps is only of limited value for the definition of the affected segment.

    ABSTRACT: The indication for nailing a femur or tibia fracture has been extended by the method of interlocking up to the meta/diaphyseal zone. For the stabilization of osteotomies in these regions, the nail was used in 16 cases of femur and 21 of tibia corrections between 1982 and 1986 in orthopedic university clinic Berlin. The osteotomies were done with a small skin incision in open way. Although there were three infections bone consolidation was succeeded in all but one patient with the planned axis. The first achieved gain in length could not be hold in five cases after removing the interlocking screws in order to give full weight bearing to the leg for callus formation. In situations of non-unions with wrong position of refracture of biologically troubled bones after plating the method of interlocking nail is stable and enables bone recovery after grafting by drilling. The possibility of early full weight bearing is a great advantage for the rehabilitation of patients, who had been suffering of the delayed healing of their leg. The nail itself preserves the right position of the bone in two dimensions, even if there are not exact fitting osteotomy fragments, and the interlocking screws secure the bone against malrotation.

    ABSTRACT: The congenital hallux varus is a rare hereditary deformity of the big toe, which often is combined either with polydactylia or with systemic deformities of the skeleton. The congenital hallux varus can be easily diagnosed clinically. The X-ray shows the ossified bony elements and provides information about the shape and number of the digits as well as their axial deviation. An operative treatment is required. So far a standardized surgical technique has not been accepted for all types of hallux varus. The correction of the bony structures and soft tissues is planned by means of preoperative scetches. The amount of correction depends on the degree of the deformity. As consequence of the reorientation of the first ray a soft tissue flap has to be planned and prepared for wound closure which otherwise would need larger grafts. Based on this series the clinical and radiological appearance of the congenital hallux varus are discussed. The operative treatment is explained step by step illustrated by photographs as well as planing scetches. Our procedures are compared to other operative methods reported in the literature. There are no diagnostic problems with the hallux varus deformity. For therapy surgery is mandatory and recommended between 9 and 24 months of age. For microsurgical preparation and correction of the deformity planning of all surgical steps and alternatives is advocated, this allows for good functional and cosmetic results.

    ABSTRACT: Hip pain during infancy is frequently harmless by nature and hardly demands any therapeutic intervention. A careful differential diagnosis is of great importance. In our study we attempted to evaluate the significance of sonography as a non-radiant and economical aid in the differential diagnosis of hip diseases during infancy. The study population consisted of children aged from 2 to 14 years, who visited our clinic with hip complaints and evident capsular distension (more than 2 mm compared to the contralateral hip joint) and without preceeding diagnosis. The study period was from 1988 to 1995. From the 82 children enrolled in this study we diagnosed Coxitis fugax (n = 54), Morbus Perthes (n = 19), Epiphysiolysis capitis femoris (n = 5), rheumatic Arthritis (n = 2), septic Arthritis (n = 1) and femoral Osteoid-Osteoma (n = 1). All patients with Coxitis fugax were scheduled for clinical and sonographic re-examination. Coxitis fugax is the most frequent disease of the hip during infancy. Perthes disease is the most important differential diagnosis up to the age of 10 years. Epiphysiolysis capitis femoris and rheumatic diseases proved to be most common differential diagnosis among elderly children. As a result of our study we were able to establish a diagnostic algorithm of hip diseases during infancy. Sonographic examination proves to be of great value especially in the differential diagnosis of Coxitis fugax and M. Perthes. In many cases the X-ray examinations which were previously mandatory could even be dispensed with. Although this concept requires careful supervision of the patients, it spares 60% of the children from undergoing X-ray examinations or MRI.

    ABSTRACT: The authors report on the incidence, clinical picture, etiology, pathogenesis and treatment of congenital pollex flexus, and communicate the results of surgery on 52 thumbs. The permanent flexion anomaly in the interphalangeal joint and a hard, palpable knot in the long flexor tendon of the thumb over the metacarpophalangeal joint are typical for the deformity. Although these changes are sometimes observed immediately post partum, delayed diagnosis and treatment are more common. The hypothesis that it is a hereditary, endogenous condition is supported by observations in twins, relatively frequent bilateral occurrence and a high familial incidence. Constriction of the synovial sheath over the basal joint of the thumb is a key pathogenetic factor, although little is known about its causes; anatomical factors, influences affecting the growth of the sesamoid bones, and mechanical causes have been postulated. A more plausible hypothesis was first advanced by Jeannin. Like Hueston and Wilson 100 years later, he compared the tendon to a thick thread which had to be passed through a narrow eye of a needle: as a result, the "thread" would be frayed and compressed. The knot in the tendon is held to be a secondary phenomenon. The pathologicoanatomical picture varies. Lymphocyte and monocyte infiltration, and metaplasias to fiber cartilage have been detected in specimens excised from the tendon and the synovial sheath. However, pathologic changes have not been found in all cases. In the first year of life conservative therapy may be attempted, with temporary splinting of the thumb following manual correction of the flexion anomaly in the interphalangeal joint.(ABSTRACT TRUNCATED AT 250 WORDS)
