[Results of follow-up of untreated anterior cruciate ligament rupture].

A series of 90 patients, 85 males and 5 females, all with ACL-ruptures had a follow up between 5 and 12 years. All of them had a primary arthrotomy with or without meniscectomy but in no case an operative repair of the ACL-rupture was done. The most concomitant injury was a torn medial meniscus in 76.3%, a damaged lateral meniscus was found in 17.1%, chondromalacia was seen in 53%, either of tibia, femur or patella. Nearly 60% of the patients could resume their former sports activities in some cases on a lower level, whereas 33% had to change their sport or even had to give up any sport. 75%-80% of the patients with partial or total meniscectomy and 90% of those without meniscectomy estimated the outcome as good or fair. In contrast to this 61% rsp. 86% of the patients with partial or total meniscectomy had an osteoarthritis of grade III and IV, patients without meniscectomy in only 23%.

Dextranomer (Debrisan) paste in post-operative wounds. A controlled study.

The clinical effect of dextranomer paste (Debrisan) in post-operative wounds (20 patients) was compared with the standard treatment in our department (polyvinylpyrrolidone, 20 patients) in a randomized study. All variables dealing with cleansing, inflammation-reducing effect and signs of ongoing healing were studied. Dextranomer paste appeared to be significantly better than polyvinylpyrrolidone in wounds with a high degree of pus and debris. No side-effects were observed in the dextranomer paste group. One patient in the control group showed an allergic reaction (oedema and erythema) and was withdrawn from the study.

[Melorheostosis, osteopoikilosis and ostiopathia striata. Their clinical significance and the value of scintigraphy in the differential diagnosis].

Melorheostosis, Osteopoikilosis and Osteopathia striata Clinical Relevance and Bone Scintigraphy Melorheostosis, Osteopoikilosis and Osteopathia striata are rare conditions. Although there is no casual therapy for any of the three diseases, differential diagnosis is important because concomitant or resulting impairments deserve orthopaedic or medical treatment. The analysis of typical cases with their clinical, roentgenological and radionuclide presentation shows the need of an accurate diagnosis to prevent senseless treatment or lost therapeutic opportunities.

[5-10-year results with the straight-shaft Müller prosthesis].

103 patients with 106 Müller straight stem prostheses could be evaluated clinically and radiologically after an average follow-up period of 6.8 years (range 5 to 10 ys.). Although until now no revision for aseptic loosening has become necessary 3 p.c. of the stems and 11 p.c. of the acetabular components showed radiological loosening. The clinical results were rated as satisfactory. After surgery 67 p.c. of the patients were completely painfree, 28 p.c. still had slight pain, 4 p.c. moderate and 1 p.c. severe pain. The investigation concentrated particularly on radiographic changes of the interface of the femur. Whereas radiolucency typically was non-progressive and located in the proximal part of the femur we found an increasing atrophy of the cortical bone on the calcar. Moreover, we found a continuous and increasing subsidence of the stem during the whole period of observation. At the time of follow up 56 p.c. of the straight stems had subsided about 2 mm and more. Calcar atrophy and radiolucency were significantly less present in femurs with a tapered medullary canal than in those with a cylindrical shape.

[2 cases of humeral head osteolysis of unknown origin].

Taking in account the medical history, the clinical and radiological presentation and the intraoperative and histological findings, two cases of osteolysis of the humeral head of unknown origin are discussed. After exclusion of underlying concomitant diseases a traumatic etiology seemed to be the most probable explanation although in both cases a trauma was denied by the patients. We are unaware of any similar cases published in the literature.

[A novel device for active shoulder rehabilitation with glenohumeral traction or compression].

The equipment available for rehabilitation of patients with joint conditions still lacks a device that, in common with usual physiotherapeutic measures (manipulation, proprioceptive neuromuscular facilitation, Bobath therapy), is based on traction and/or compression or oscillating forms. The novel "Shoulder Rotator" is such a simple device for the variable treatment of shoulder disorders in all three spatial dimensions. After individual instruction, the patient performs rotating glenohumeral exercises with simultaneous glenohumeral joint traction, compression, or oscillations against static or dynamic resistance. The "Shoulder Rotator" is similar to the established continuous passive motion device for the shoulder and is mounted on a mobile chair. The electronic device control is computerised and permits a wide variety of treatment options, individual regimes, and documentation. The oscillating, compression/distraction mode of operation provides an analgesic effect. The isolated compression mode along the rotatory axis enables conditioning of joint proprioception. The distraction mode along the rotatory axis facilitates muscular relaxation. Resistive rotatory exercises strengthen the rotatory glenohumeral muscles and help centre the humeral head in the glenoid. In addition to the advantage of adding documentation of treatment progress as required for evidence-based medicine, this novel device may bring about a cost-effective, genuine quality improvement in shoulder rehabilitation.

The operative treatment of humeral shaft fractures.

Although conservative treatment is still the treatment of choice in simple humeral shaft fractures, there are some distinct indications for operative stabilisation, namely association with other injuries or conditions aggravating the traumatic impact of the in itself banal fracture. These indications are discussed and our 41 operatively treated humeral shaft fractures are reviewed.

Inguinal hernia repair leading to the diagnosis of internal male pseudohermaphroditism.

Surgical hernia repair in an apparently normal man leaded to the diagnosis of internal male pseudohermaphroditism after removal of a cystic structure which proved to be a remnant of the Müllerian duct on microscopic examination. The diagnosis was confirmed at explorative laparotomy in search of the second testicle. The terminology of the condition is reviewed and the therapeutic attitude is discussed.

[Aseptic pseudoarthroses of the long bones].

When treating fractures, whether by closed or open technique, the event of a pseudarthrosis is always a threatening complication. Absolute immobilization of the fracture site and tissue viability are the two essential conditions to obtain ossification of a pseudarthrosis. Consequently, after a reasonable period of conservative therapy, consolidation can best be obtained by osteosynthesis associated with decortication and/or cancellous bone grafting. The application of the two biomechanical laws is demonstrated in our series of 32 cases with pseudarthrosis.
