[MRI as decisive diagnostic procedure in Perthes disease. Early diagnosis of femoral head necrosis in childhood].

PROBLEM: In order to achieve better final results in Perthes disease, the diagnosis should be established as early and as accurately as possible. This is rarely achieved with conventional X-ray procedures. OWN EXPERIENCE: Since 1986, a total of 50 children with Perthes disease were submitted to MRI follow-up examinations employing T1 and T2-weighted coronary an sagittal sections and the results compared with the findings of conventional X-ray examinations. RESULTS: The authors developed their own MRI staging and typing scheme on the basis of the MRI extent of the necrosis. Catterall's group classification could not be translated to the MRI since the latter usually showed more extensive necrosis. Agreement was found only in group I. With the aid of MR imaging, it proved possible to diagnose a case of Perthes disease earlier, the total extent of the necrosis was established earlier, and also the final form of the epiphysis after completion of re-modelling was already predictable in stage II. The indication for treatment and intra-trochanteric osteotomy was established on the basis of the MR image. Further invasive investigations were not needed. CONCLUSIONS: In the case of Perthes disease, MRI should be given preference over other diagnostic procedures and, despite the greater expenditure of time and greater cost, should be routinely employed in this disease.

[Structures of the knee joint in nuclear magnetic resonance tomography. Improved representation with 3D volume imaging].

Despite 3D gradient echo technique has a better spacial resolution than spin echo sequences, 3D imaging is not well accepted for clinical routine. Because of the large amount of data evaluation cannot be done by single photo-documented slices. Postprocessing of the 3D data sets with an image analysis system is indispensable. A maximum of two different gradient echo sequences (FLASH, FISP) are necessary for imaging of the whole interesting volume with continuous slices. Time of examination is shorter (16 resp. 32 minutes) compared with conventional spin echo sequences. In our opinion 3D gradient echo-sequences are a reliable noninvasive technique for the evaluation of pathological changes of the knee joint which could replace diagnostic arthroscopy in the future.

Osteoblastoma of the coccyx. A report of two cases.

Osteoblastoma, defined as a benign bone tumor by Jaffe and Lichtenstein, together with osteoid osteoma and multifocal osteoblastoma, belongs to the osteoblastic tumors. Due to the variable features of this tumor, differential diagnosis comprises fibrous dysplasia, giant cell tumor, aneurysmal bone cyst and osteoid osteoma; histological analysis is the only way to obtain a definite answer about the tumor type. Occasionally differential diagnosis from aggressive osteoblastoma and osteosarcoma may be difficult. The history of symptoms is usually long and diagnosis may be difficult both clinically and histologically.

Cementless prosthesis of the hip joint with "spongy metal" surface. A prospective study.

Our investigations in human specimens and animal experiments show that prostheses with a spongy metal surface can become fixed by bony ingrowth to varying degrees. After consistent clinical and radiological follow-up over 12-65 months (mean 34 months) in a prospective study of 100 consecutive patients in whom 106 cementless total hip replacements had been carried out, we were able to show that after 1 year 82% of patients were pain-free with the prosthesis fixed by bony ingrowth, 8% were pain-free with the prosthesis fixed by dense fibrous tissue and 10% were not pain-free, but did not want revision surgery. Thigh pain decreased steadily from 53% 3 months postoperatively to 6.6% 15 months after operation. We believe that, when the implantation technique is exact, a high percentage of cementless spongy metal prostheses are fixed by bony ingrowth, and that a cementless prosthesis should be implanted only in patients under 60 years of age without osteoporosis.

[Arthroplasty of the upper ankle joint. Possibilities and limitations].

It is out of the question that alloarthroplasty of the upper angle joint must today belong to the therapeutic repertoire of the orthopedic surgeon. The anatomical situation of the upper ankle joint brings considerable problems for the total replacement and then also for the surface replacement. At the time being models are already available, which, seen on the whole, have already brought quite reliable results. Requirement for the success of the operation is the technically perfect insertion of the surface replacement or of the total joint and furthermore the insertion of the replacement under appropriate conditions, whereby the operation in an aseptive room ("Reinraum") has proven itself effective also on the upper ankle joint.

[The medical situation in Bhutan with special consideration of mountaineering].

Several thousand mountaineers a year from Germany alone visit high mountains (4000 to 7000 m) in non-european countries. This number si steadily increasing and it seems necessary to familiarize oneself with the medical situation in these countries. Compared to other countries we saw that in Bhutan rescue is possible within a short time, because of the rather short distances between trekking routes and the Thimphu General Hospital. Medical staff in this hospital is very cooperative, for instance if a patient with severe joint injuries should be transferred to Europe for treatment with all possibilities of bone and joint surgery. Generally, however, we recommend to establish special rescue stations in various places with wireless equipment in order to get help as soon as possible in case of emergency and to avoid delayed rescue or transportation under poor conditions (horse back).

[Fracture of the vertebrae due to riding accidents].

Fractures of the vertebral column due to riding accidents are frequent. In most of the cases we observe compression fractures of a vertebral body without compression symptoms of the spinal cord. If fractures of the spine heal with a gibbus deformity degenerative changes of the vertebral joints with severe back pains may ensue. Therefore it seems necessary to treat fractures of the vertebral spine with immediate reposition (ventraler Durchhang) and following immobilisation with a plastic corset Lightcast, Hexcelite). Occasionally operative stabilisation is necessary, especially in fractures of the cervical spine.

[Ski boots from an orthopedic point of view].

1. A ski-boot should have an adequate arch support and a variable, as well as an exact fitting of the dorsal part. This can be achieved with flow, foam, air or wax. 2. Isolated pressure of compression systems of different kinds should be avoided (e.g. pressure of buckles above the ankle). New results are demonstrated by the possibility of putting on the boot from behind and having the buckles at the back of the boot. 3. The strap from ankle to foot has to be continuous to avoid pressure points. 4. It should be possible to walk and stand in a ski-boot without either muscular strain or pressure on the knee-joint. In addition, the sole has to give an optimal grip also on icy ground to prevent slipping.
