Erdheim Chester disease: a rare cause of knee and leg pain.

A case of Erdheim Chester disease in a 51-year-old Turkish patient is described. Erdheim Chester disease is a rare form of lipoid granulomatosis. Knee and leg pain are the most common symptoms, and physicians working in orthopaedics and traumatology are the first to be consulted. Our patient demonstrated a typical bilateral, symmetric sclerosis of the metaphyseal region of long bones of the lower extremity, histologic examination revealed foamy, lipid-loaded histiocytes. The patient also suffered from arterial hypertension, diabetes insipidus and exophthalmos of the left eye. The diagnosis was confirmed by a bone biopsy, and the patient was treated with non-steroidal anti-inflammatory drugs, corticosteroids and vincristine.

[A cellular quantitative immune deficiency in chronic post-traumatic osteomyelitis].

The specific cellular host defence in patients with chronic post-traumatic bone infection was analyzed in a prospective study. The study included 120 patients with chronic post-traumatic osteomyelitis and 60 healthy volunteers. The number of CD-5, CD-4, CD-8, natural killer cells and the CD-4/CD-8 ratio were significantly decreased. The immunodeficiency seems to be trauma-induced and reinflammation seems to be due to other immunodeficient factors. The potential key role of a defect in cytokines is discussed.

[Malposition of healed distal radius fracture. Indications, technique and timing of correction].

Typical complications of distal radius fractures include post-traumatic malalignment in about 20%. This is associated with ulno-carpal pain and impaired wrist function. Various corrective procedures have been recommended. Between 1972 and 1986, 96 patients with posttraumatic disorders after distal radius fractures underwent surgical treatment. Three different procedures were carried out: simple corrective osteotomy of the distal radius, combined correction of the radius and ulna, as well as isolated correction of the ulna (distal resection, step-cut osteotomy, hemiresection arthroplasty). 83 (86.5%) of the patients were followed up for an average of 7 years postoperatively. The functional results were evaluated according to Lidström. Excellent and good results were found in 58 (69.9%), fair in 20 (24.1%) and bad results in 5 (6.0%). The best results were mostly seen in cases with a short interval between trauma and corrective procedure. Distal ulna resection has not been performed in our department since 1986 because of poor results and concommitant wrist-instability. We recommend combined correction procedures in those patients with painful deformities within a period of no more than six to nine months after trauma. The indication should also take individual aspects such as profession, age, activities, complaints, and radiological findings into account. Signs of osteoarthrosis and wrist disorders due to severe soft tissue problems are contra-indications to any of the aforementioned correction procedures.

[Complications, side-effects and contraindications in the use of medium and high-energy extracorporeal shock waves in orthopedics].

INTRODUCTION: Possible complications and side effects using extracorporeal shock waves for orthopaedic diseases should be evaluated. METHOD: Since 1993 we prospectively evaluated the complications and adverse effects applying extracorporeal shockwaves for orthopaedic diseases. Within three years 542 lithotripsies in 276 patients were made. 190 patients were treated because of calcifying tendinitis, 34 for epicondylitis and 52 suffering from a plantar heel spur. RESULTS: In 216 cases we could recognize small superficial hematomas, 4 hyperventilations and in 3 cases a blood pressure elevation over 200 mmHg. Two cases of high blood pressure showed data over 200 mmHg without other clinical symptoms. They were of transitory nature during therapy. In one case we had to treat a hypertension crisis within the first 3 hours after therapy. Today the application of shockwaves in the thoracic region or lung, coagulopathies or anticoagulant medicine, pregnancy and the use at nerval or vascular structures represent an absolute contraindication. When using extracorporeal shock waves for bone lithotripsy, bone tumors, bone infection or infected pseudarthrosis and the application at growth plates in children and young adults represent an absolute contraindication. CONCLUSION: In general lithotripsy has only minor complications when it is used accurate.

[5-years lithotripsy of plantar of plantar heel spur: experiences and results--a follow-up study after 36.9 months].

INTRODUCTION: Effectivity and application as well as possible complications and side effects of extracorporeal shock wave lithotripsy of plantar heel spurs should be evaluated. METHOD: We applied extracorporeal shock wave lithotripsy (ECSL) to treat plantar fasciitis in 54 patients (period from: 3/1/1993 to 3/1/1996). 20 persons were treated with Lithostar plus (group 1) and ultrasound focussing and 34 patients (group 2) were treated by a Lithostar and X-ray focussing. RESULTS: After 6 weeks 14 (70%) of group 1 and 27 (79.4%) of group 2 were free of pain. After 36.9 months 8 (40%) of group 1 and 23 (67.6%) of group 2 were still painfree. We could not recognize any severe complications after 36.9 months. CONCLUSION: ECSL is an effective and noninvasive method of treatment. It is not the method of choice for the first treatment of plantar fasciitis but is an alternative option for operation.
