[Congenital pseudarthrosis of the legs and the Ilizarov method. Apropos of 4 cases].

Four cases of congenital pseudarthrosis were treated by the Ilizarov method and consolidation obtained by 3.5 months in three patients who had all undergone several previous surgical procedures. Although the length of follow up is short (maximum 3.5 years) consolidation occurred quicker than by traditional methods. This technique also permitted both simultaneous correction of axial malalignment and leg lengthening. We think that this method has a place as a salvage procedure except where the distal fragment is very thin or dystrophic.

[Meniscal lesions in so-called "isolated" ruptures of the anterior cruciate ligament. Apropos of 59 cases].

Between December 1984 and March 1987, i.e. a period of 27 months, the authors operated on 59 "isolated" fresh ruptures of the ACL with routine evaluation of the posterior horns of the medial and lateral menisci. Lesions were investigated either by arthroscopy (23 cases) or by anterior arthrotomy with routine medial and lateral retro-ligamentous counter-incision (36 cases). This revealed 21 lesions of the medial meniscus (i.e. 35.5%) and 38 lesions of the lateral meniscus (i.e. 64.5%). Lesions of both menisci were present in 16 knees (27%) and only 16 knees (27%) were found to be free of any meniscal lesion. The majority of meniscal lesions were viable and could be sutured in 86% of cases for the medial meniscus and 87% of cases for the lateral meniscus. From the standpoint of operative technique, posterior lesions are relatively poorly visualized by arthroscopy (notably concerning the posterior horn of the medial meniscus though it is easier to assess the stability of the meniscus by this technique using the palpating hook. Lesions are well visualized by medial and lateral retroligamentous counter-incisions, but it is difficult to assess meniscus stability. Finally it should be noted that all of these ruptures of the ACL were dealt with by reconstruction of the central pivot either by suture and a strengthening procedure (semitendinous) or by ligament plasty from the outset.

[Antibiotic prevention and appendectomy. Practical consequences for health economics. Apropos of a series of 642 cases].

A total of 642 patients undergoing appendicectomy were divided into two groups of 321 patients prior to surgery. One group (A) received prophylactic antibiotic therapy, the other (B) no previous treatment. Patients were from the same region and groups were comparable for age, sex and indications for operation. Antibiotic treatment was administered according to a personal protocol based on gross appearance of appendix, and involved two molecules: Baypen in 69 cases and cephamycin (Mefoxin) in the other 252. Although not a randomized trial, the protocol was considered effective for prevention of postoperative infectious complications. In the group A, 21 patients (6.54%) developed these complications as against only 3 (0.93%) in group B, a significant difference if the total group B is considered or the two antibiotic subgroups. However, no valid conclusion can be drawn in favor of one or other of the two molecules. This effective procedure reduces by a half the duration of postoperative hospital stay for patients with a simple acute or a chronic appendicitis accepting the follow up surveillance required by the protocol. This attitude should be extended to a larger number of patients with resulting non-negligible health costs economy.

[Butel's hip screw-plate in osteosynthesis of fractures of the upper end of the femur. Apropos of 241 osteosyntheses (100 true cervical fractures and 141 fractures of the trochanter)].

Butel's hip plate was used for osteosynthesis of 241 fractures of upper end of femur (100 true cervical - 141 trochanteric and subtrochanteric fractures). Results for true cervical fractures were assessed as satisfactory in 89.5% of cases, with only 3 pseudarthroses and 4 cases of femoral head necrosis (2 septic, 2 aseptic), a total complication rate of 7.5%. These clinical results confirm the value of screw fixation at several cephalic anchorage sites (demonstrated biomechanically) in true cervical fractures. Results in trochanteric and subtrochanteric fractures were rated as satisfactory in 86.9% of cases, complications including 2 ruptures of plate, 1 sepsis and 4 early loosening of plate. The latter sequela was avoided by an improved choice of indication for the procedure and by substitution of this compound material (screw-plate) for a monobloc piece ("anti-loosening cervicocephalic screw apparatus"), in compound fractures of trochanter.

[Fractures of the lower end of the humerus in adults: influence of per- and postoperative tactics on results. Apropos of 70 osteosyntheses].

Results in 70 cases of osteosynthesis of lower end of humerus in adults were analyzed as a function of the fracture line, and the operative (approach route, type of support, attitude towards ulnar nerve transposition) and postoperative (with or without plaster immobilization) tactics. Best results were obtained in simple joint fractures (condyles, capitellum, Hahn Steinthal) with a good outcome in 89% of cases, while prognosis was poorer (68.5% of delayed good results) in more or less comminuted supra- or inter-condylar fractures (41 cases). Results are better in these latter types of fracture when an extra-articular trans-olecranon posterior approach is used. Ulnar nerve transposition was performed 43 times without adverse effects and osteosynthesis by 2 posterior screw plates (one on external and one on internal column) in 50% of cases. Valid comparison of results with or without postoperative plaster immobilization was not possible since only 8 patients were not plastered.

[Role of intermediate sealed prostheses in the treatment of fractures of the trochanter major in the elderly. Apropos of a continuous series of 110 prosthesis].

Between January 1980 and July 1983, 265 fracture of the trochanteric region in elderly patients were treated in Prof. J. Butel's department. Prior to 1980, 75% of the cases were treated with Ender's pin. However, the high failure rate of this procedure (especially in the case of complex fractures) led the authors to select the indications for this operation much more carefully. In the present series of 265 cases, there were: 110 intermediate sealed prostheses, 136 Ender's pin 19 direct osteosyntheses. At the present time (and for the last 2 years) the indications are distributed in the following way: 50% intermediate sealed prostheses, about 40% Ender's pin and 5 to 10 direct osteosyntheses. The ideal indication for intermediate sealed prosthesis is a unstable fracture of the greater trochanter (complex trochanteric fractures, fractures with a large 3rd fragment separating the lesser trochanter, trochantero-diaphyseal fractures) in autonomous elderly patients over the age of 75. This operation allows immediate weight-bearing and the operative mortality is barely more than with other techniques (21%) with very satisfactory results (more than 80 of good and very good results).

[Trochanteric fractures in the elderly: Ender nails, prostheses or direct osteosyntheses. Apropos of a continuous series of 265 cases].

The results of 265 trochanteric fractures in the elderly treated between 1980 and 1983 have been analysed. Among them, 136 were treated by Ender's nailing, 110 by prostheses and 19 by internal fixation. In an earlier study, Ender's nailing had been used in 75 p. 100 of cases. The conclusions were that the increasing use of a prosthesis has brought about an improvement in the results-80 p. 100 satisfactory in the present series compared with 54 p. 100 in the preceding one. The mortality rate was comparable after Ender's nailing and prostheses. Ender's nailing is indicated in stable fractures and, in unstable fractures, internal fixation is indicated in very active persons, Ender's nailing in non-ambulatory patients and prostheses in elderly patients with sufficient walking ability.

[Mammary lymphatic scintiscans by intratumoral injection in the assessment of breast cancer. 105 examination in 100 patients (author's transl)].

One hundred and five scintiscans of the mammary lymphatic system were performed in 100 patients with breast cancer by intratumoral injection of 99 m Tc-labelled colloidal rhenium. The progression of the radioactive colloidal agent was followed on a series of films taken 1, 2 and 4 hours after the injection, and the images obtained were compared with post-operative findings of lymph node involvement. Patients with more than 3 carcinomatous lymph nodes had less than 2 foci of activity, while those with less than 3 carcinomatous lymph nodes had more than 2 foci of activity, owing to more rapid progression of the compound. The difference was highly significant (p less than 0,001).

[Paraganglioma of the organs of Zuckerkandl. A case report (author's transl)].

Endocrine manifestations were absent in a patient presenting with pain in the left peri-umbilical region from a paraganglioma of the organs of Zuckerkandl. The authors describe the embryology of paragangliomas and review the published literature concerning the noradrenaline-secreting forms of these tumors. Only 86 references to those of Zuckerkandl, situated on the side of the aorta in relation to the inferior mesenteric artery, were found. Diagnosis of non-secreting forms is confirmed by arteriography which in this present case demonstrated three pedicles arising from the inferior mesenteric, celiac, and one of the lumbar arteries respectively. The only evidence of malignancy is the presence of metastases. Their diagnosis is therefore difficult but essential as one-third of the localisations of malignant pheochromocytomas (10 p. cent of pheochromocytomas) outside of the adrenals affect the organs of Zuckerkandl.
