Résultats de la technique de Mac Intosh au Fascia Lata Modifiée par Jaeger dans les instabilités antérieures chroniques du genou

Objectif: Il existe plusieurs techniques de reconstruction des ruptures anciennes du ligament croisé antérieur du genou. Le but de cette étude était d'évaluer à moyen terme les résultats de la technique de Mac Intosh au fascia lata modifiée par Jaeger. Matériel et méthodes: Dans cette étude rétrospective réalisée entre janvier 2005 et décembre 2013, 56 genoux (56 patients) ont été opérés par la technique de Jaeger à ciel ouvert pour des ruptures anciennes du ligament croisé antérieur. Elle a concerné des adultes jeunes masculins. Cinquante (89%) patients étaient sportifs. Un patient avait une arthrose débutante classée stade 2 Alhbäck modifiée. L'évaluation fonctionnelle des résultats a été faite selon le score IKS (globale, genou et fonction). L'examen clinique était basé sur la mobilité du genou, le test de Lachman-Trillat, et la recherche du ressaut. Le positionnement du tunnel tibial a été analysé à la radiographie. Le stade arthrosique a été apprécié selon les critères d'Alhbäck modifié . La ligamentisation du transplant à l'IRM a été étudiée chez quatre patients. Résultats: Au recul moyen de 7 ans, 85% des patients étaient satisfaits du résultat fonctionnel avec un score IKS genou de 96,1 en moyenne, un score IKS fonction de 100, et un score IKS global de 196,1. La mobilité était complète sans flessum résiduel. Le test de Lachman-Trillat était négatif (n= 38 ; 68%). Il était positif avec arrêt dur (n=16 ; 29%) et retardé (n=2 ; 3%). Le ressaut rotatoire a été neutralisé chez tous les patients. L'angle tibial moyen de face était de 61°. Il n'y avait pas de ballonisation des tunnels. Cinquantedeux (93%) patients étaient classés Alhbäck 1 et quatre (7%) Alhbäck 2. La ligamentisation a été constante à l'IRM. Conclusion: La ligamentoplastie du croisé antérieur au fascia lata modifiée par Jaeger donne de bons résultats fonctionnels et anatomiques avec une réduction significative de l'apparition de l'arthrose secondaire

Chimiotherapie des cancers du col de l'uterus au stade IV a vesical a l'Institut Curie de Dakar

Les cancers du col de l'uterus au stade IV ne relevent plus de la combinaison standard radio-chirurgicale. Aussi dans notre contexte marque par les difficultes de tous ordres pour correctement appliquer la chimiotherapie; nous avons pense opportun de retracer notre experience dans l'utilisation de moyen therapeutique dans les cancers du col uterin classes IVa vesical a Dakar. Sur 91 dossiers retenus; 80 ont concerne la mise en oeuvre de la combinaison chimiotherapie et radio-therapie selon diverses modalites. Les resultats enregistres dans la pratique de cette modalite nous poussent a proposer la procedure chimiotherapie neoadjuvante suivie de radiochimiotherapie dans notre contexte en l'absence de curietherapie pour ameliorer la survie

Femur malunion treated with open osteotomy and intramedullary nailing in developing countries.

INTRODUCTION: In developing countries, malunion, after diaphyseal femur fractures initially untreated by internal fixation, is not rare. Their difficult management contrasts with the deficiency of the technical operating room facilities. PATIENTS AND METHODS: Our prospective study, conducted over a 1-year period, reports 16 open osteotomies fixed using Küntscher intramedullary nailing in patients who presented malunion of the femoral diaphysis. Twelve males and four females (mean age, 34.5 years; range, 18-67 years) were managed with a mean time to surgery of 8 months (range, 4-14 months). All had initially consulted a bonesetter. The mean length inequality was 3 cm (range, 2-6 cm); the mean knee flexion limitation was 90° (range, 10°-120°). Locking of the rotation was obtained by the obliquity of the osteotomy line. No bone filling was added but reaming and decortications were systematic. The patients were clinically and radiographically assessed at D21, D45, D90, and D120, based on the evaluation of the length inequality, mobility, and bone union. Rotational malunion or deformity were not analyzed. RESULTS: Fifteen patients had achieved union in 90 days. In one case, secondary incurvation of the nail led to changing the nail, allowing union with no axis deformity at D120. The mean postoperative knee flexion was 120° (range, 45°-130°). The mean gain in length was 2 cm (range, 1.5-4 cm). DISCUSSION: This open technique using non-interlocking material allowed us to obtain bone union while improving joint mobility and length inequality. LEVEL OF EVIDENCE: Level IV. Retrospective study.

[Morel-Lavallée lesion in orthopaedic surgery (Nineteen cases)]. / Épanchement de Morel-Lavallée en chirurgie orthopédique (À propos de 19 cas).

AIMS: The object of this work is the study of especially ancient clinical forms of the effusion of Morel-Lavallée, to discuss the place of deep fascial fenestration by Ronceray and to propose criteria of therapeutic indication. PATIENTS AND METHOD: Our study concerns a continuous retrospective series over 20 years from 1989 till 2009. Eleven men and eight women, 36.7 year-old on average were treated for an effusion of Morel-Lavallée. The dominant etiology was represented by the accidents of the public highway. The collection was discovered after 41.4 days on average (extremes of 1-180 days). The volume of the collection was on average of 1237cm(3) (extremes 60cm(3)-12L). RESULTS: The conservative treatment concerned all patients who had a recent collection lower than three weeks and three others who had an ancient collection. The surgical treatment was established after all 10 times among which four in first intention and six times after failure of the previous treatment. The cure was obtained in 91% of the patients who had a recent collection by the only conservative method and among four patients by the method of Ronceray. To the three others, it was obtained after iterative unbridlings and talcage treatment. CONCLUSION: The authors insist on certain rare forms met in Africa in particular the "virtual form", the ancient forms and the too plentiful forms (12L). They plead for use deep fascial fenestrations by Ronceray for these last ones.

[Primary lymphoma of the thyroid: a case report]. / Lymphome primitif de la thyroïde: a propos d'un cas.

Primary lymphoma of the thyroid is an uncommon disease. It diagnosis is difficult without immunohistochemestry. We report a case of thyroid lymphoma diagnosed at the A. Le Dantec Hospital of Dakar. A 22-year old young man presented anterior neck mass. Clinical examination showed a thyroid mass with a susclavicular palpable lymph node. The scintigraphy demonstrated that the mass was cold. Total thyroidectomy with cervical lymphadenectomy was the first treatment. Histological examination of the surgical specimen concluded that the mass was an anaplastic lymphoma (large cells type) involving the sus clavicular lymph nodes (stage IIE). Chemotherapy was administrated after one month with C-MOPP schedule. The patient presented no recurrent sign after 30 month. Fine needle aspiration and immunocytochemestry of the thyroid cold masses will contribute in an accurate diagnosis and the management of disease in our institution.

Il s'agit d'une etude retrospective de 46 cas de cancers du sein survenus chez l'homme et colliges a l'institut du Cancer de Dakar de 1957 a 1999. L'age moyen des malades etait de 60;7 ans et la duree moyenne des symptomes etait de 37;5 mois. La repartition des malades selon la classification TNM de l' UICC revelait : 1T1; 1T2; 4T3; 40T4; 40N1; 1N2; SN3; 10M1 PUL; 8M1 OSS et 2M1 HEP. Le carcinome canalaire invasif representait 78;2 pour cent de l'ensemble des lesions histologiques. Nous avons realise 32 mastectomies dont 23 etaient associees a un curage axillaire. La chirurgie etait associe a une chimiotherapie dans 25 cas et a une radiotherapie dans 14 cas. Le traitement hormonal au Tamoxifene fut institue dans 7 cas. Le suivi moyen des malades etait de 24 mois. Le pronostic de ces cancers pourrait etre ameliore par une meilleure education et un diagnostic plus precoce

[Complications of colpohysterectomy with lymph node dissection in the cervix carcinoma at the Cancer Institute of Dakar: report of 412 cases]. / Les complications des colpohystérectomies élargies avec lymphadénectomie pour cancer du col utérin à l'Institut du Cancer de Dakar: à propos de 412 cas.

The wertheim complications are dominated by the urinary dysfonction and the lymphocele which are linked at this procedure. This study reported 412 Wertheim associated to the radiotherapy. The purpose was to evaluate the complications among patients who underwent the Wertheim and to analyse the differents factors promotions the complications. The diagnosis was always late and the disease stage was advanced. The stages II, III and IV represented more than 80%. We found 86 complications (20.87%) distributed as follow: 17 urinary (19.76%), 30 secondary infections (34.88%), 8 colonic fistula (9.30%), 7 hemorrage (8.13%), 6 lymphedema (6.97%), 3 occlusions (3.48%), 1 phlebitis (1.16%), 1 lymphocele (1.16%). among all patients, 17 died, the mortality rate was 4.12%. A very good dissection preceded by radiotherapy may reduce the complications rate.

[Cancer of the uterine cervix in pregnancy: report of 50 cases]. / Cancer du col de l'utérus et grossesse: à propos de 50 cas.

Through a retrospective study of 50 cervix carcinoma during pregnancy, the authors determine the epidemiology, discuss the therapeutic and the pronostic. The mean age of patients were 36 years and the clinical staging of FIGO found : 3 stages Ia, 3 Ib, 7 IIa, 14 IIb, 7 IIIa, 7 IIIb, 4 IVa, 5 IVb The diagnosis of carcinoma was in 6 cases(12%) at first trimester, in 6 cases(12%) at midtrimester, in 13 cases(27%) at third trimester, in 19 cases(28%) after delivery. The termination of pregnancy was an abortion in 6 cases(12%). The treatment was: 29 delivery whose 12 followed bycolpohysterectomy,1 byconisation and 16 had not a colpohysterectomy. 5 cesarean section whose 2 followed by colpohysterectomy in the same time and 3 in the second time. The radiotherapy was neoadjuvant in 3 cases and adjuvant in 3 cases. The mortality was 4 % and the global survival at 5 years was 30%. The prognostic of the cervix carcinoma during pregnancy would get better by Pap test which must be systematic at the pregnant woman.

[Breast cancer and pregnancy: about 60 cases collected at the Cancer Institut of Dakar]. / Cancer du sein et grossesse: à propos de 60 cas colligés a l'Institut du Cancer de Dakar.

The purpose of this retrospective study of 60 breast carcinoma during pregnancy collected at the Cancer Institut of Dakar from 1962 to 1998 was to determine the epidemiology, the clinical appearance and to discuss the pathogeny, the diagnosis, the prognosis and the treatment. The mean of age of patients was 34.5 years. The number of parity was 5 and the first pregnancy at 20 years. The authors arrived at diagnosis in the post partum in 28 cases (47.45%), in the first trimester in 8 cases (13.55%), in the midtrimester in 13 cases (22.03%) and in the third trimester in 11 cases (18.64%). The polychemotherapy preceded the surgery in 30 cases and succeded in 16 cases. The hormonotherapy with Tamoxifen prescribed in 17 cases after the delivery. The mastectomy and axillary lymphadenectomy was realised in 26 cases in the post partum. The adjuvant radiotherapy was done in 12 cases. The mortality was 31% and the global survival at 2 years, 34.6%.

[Vulvar cancers. Retrospective study of 23 cases at the Cancer Institute of Dakar]. / Les cancers de la vulve. Etude rétrospective à propos de 23 cas colligés à l'Institut du Cancer de Dakar.

The vulvar cancer is an uncommon disease which is beginning mostly on vulvar intraepithelial neoplasma and it keeps a very bad prognostic. The purpose of this study is to report the epidemiological, the anatomo-clinic and and to discuss the treatment. We tell about 23 vulvar cancer from 1956 to 1995 which were followed at the cancer Institut of Dakar. The mean age of patients is 47 years and they are on menopause in 78.6%. The most of the tumors are ulcerate (96%). The clinical investigation find according the staging of FIGO: 15 tumors (T2), 8 tumors (T3), 6 tumors (N1), 9 tumors (N2) and 1 tumor (M1b). The surgery is the principal treatment with 6 radical vulvectomy and 17 palliative vulvectomy. The surgery was associated with radiotherapy and chemotherapy. So the vulvar cancer is uncommon in our country and concern the young wives. The vulvectomy with lymphadenectomy is the principal treatment; the prognostic still very bad because the diagnostic is often later.

[Epidemiological and therapeutic aspects of rectal cancer in Senegal: 74 cases at the Cancer Institute of Dakar]. / Aspects épidémiologiques et thérapeutiques des cancers du rectum au Sénégal: à propos de 74 cas colligés a l'Institut du Cancer de Dakar.

Through a retrospective study of 74 cancer of rectum the autors determine the epidemiology, the anatomic appearance and discuss the treatment, the prognostic. The mean age of patients was 48 years and the Duke's staging found: 16 stages B, 46 stages C and 12 stages D. The pathological anatomy showed: 58 adenocarcinoma, 9 colloïdal adenocarcinoma, 4 epidermoïdal carcinoma, 2 lymphosarcoma, 1 anaplasic adenocarcinoma. The operability rate was 66.2%, the resectability was 40.8% and the sphincteral preserving was 8.1%. The radiotherapy preceded the surgery in 6 cases and associated the chemotherapy. The chemotherapy preceded the surgery thein 14 cases and succeeded in 2 cases. The mortality was 24.4% and the recidivation 35%. The global survival 5 years was 32%. The prognostic could better by an earlier diagnostic and a multidisciplinary treatment.

[Cancers of the anus: 32 cases]. / Les cancers de l'anus: à propos de 32 cas.

The purpose of this retrospective study about 32 anal carcinoma was to determine the epidemoilogy, to discuss the therapeutic indications. The mean age of patients was 56.42 years and the protologic antecedent was 14%. According to the clinical staging: 1 patient was T1, 2 T2, 19 T3, 10T4; 1 No, 2 Nx, 7 N1, 10 N2, 12 N3; 25 M x, 5 MO, 2 M1. The histologic classification of OMS found: 17 epidermoid carcinoma, 12 glandular carcinoma, 1 transitional cell carcinoma, and 1 non classify cancer. 14 radical resection and 3 local resection were realised, 8 patients had an exclusive radiotherapy: 2 curative radiotherapy and 6 palliative. The morbidity was 9.37% and dominated by perineal suppuration and the mortality was 3.12%. The adjunctive radiotherapy must be the first treatment of the anal cancer in our countries.

[Epidemiological factors, treatment and prognosis of uterine sarcomas: 14 cases at the Cancer Institute of Dakar]. / Etude des facteurs épidémiologiques, du traitement et du prognostic des sarcomes de l'utérus: à propos de 14 cas colligés à l'Institut du Cancer de Dakar.

The study of uterus sarcoma took in interest because these tumors were unrecognized and sat nowadays many questions. The purpose of this study is to review the epidemiological factors, the problems of treatment and prognostic of uterus sarcoma. It's a retrospective study of 14 sarcomas of uterus reported from 1959 to 1997. The mean age of the patients was 54 years and they were on menopause in 78.6%. The clinical investigation found according the FIGO staging: 6 stage I (42.6%), 4 stage II (28.4%), 1 stage III (7.1%) and 3 stage IV (21.4%). The leiomyosarcoma (42.6%) appeared as the more frequent histologic lesion. Surgery was the principal treatment: it was alone on 3 cases (24.9%), associated with chemotherapy on 8 cases (66.8%) and one patient had an association surgery, chemotherapy and radiotherapy. The global survival was 21.4% at 2 years and all the patients were dead at 5 years and it seemed that it would be better when the patients were treated by radical surgery associated with chemotherapy and radiotherapy.

[Cancers in the scars of thermal burns (apropos of 67 cases)]. / Les cancers sur cicatrices de brulures thermiques: (àpropos de 67 cas).

Burns are very frequent. Skin cancer on burns scars are one of the known complications. The mechanisms and the risk factors of this disease are not very well known. To review the risk factors and the mechanisms of transformation of burn scars into cancer, we analyzed 67 retrospective cases of Marjolin's ulcer to describe the epidemiological features of the disease in our practice and identify the factors of relapse. Our patients are young (means age 41), mainly male (54%), with disease localized on arms and legs (88%). The initial burn was from flames (54%), charcoal or hot cooking oil (19.5%) and never from ionizing radiation. It was never a superficial burn and covered from 4 to 37% of the body surface (mean 14%). The initial treatment was medical in only 9% of cases and ended with 85% of complete healing. After 4 to 67 years of evolution, 95% of re-ulceration occurred. Abnormal lymph node and distant metastasis were diagnosed in respectively 68 and 7% of the cases. Amputation and groin dissection were respectively done in 63 and 50%. One third of patients were lost during the follow up. 25% of the cases are still alive and free of disease. We found 30% of local recurrence and 17.5% of regional recurrence. By univariate analysis we found that the factors significantly associated to loco-regional relapse are: male status (p = 0.0327), burns by cooking oil (p = 0.0118), lack of treatment during initial burn (p = 0.0001), sclerous scar (p = 0.0281), supra regional lymph nodes (p = 0.028) lack of treatment during re ulceration (p = 0.0308). Squamous cell carcinomas on burn scars are rare diseases and of bad prognosis. Mainly associated to domestic accidents they frequently occur on limbs and arms on an articulation. Metastasis is not frequent. Conservative treatment is associated with 30% of recurrence. In our practice, the relapse risk factors are male status, burns by cooking oil, lack of treatment during the initial burn, sclerous scar, supra regional lymph nodes, lack of treatment during re ulceration.

[Risk factors for lymphedema of the arm after mastectomy for breast cancer]. / Les facteurs de survenue des lymphoedèmes du membre supérieur après mastectomie pour cancer du sein.

Postmastectomy lymphedema of the arm is frequently associated to different factors including axillary node involvement and local and regional treatment of breast cancer. Our aims was to identify risk factors of postmastectomy lymphedema. From a retrospective analysis of 735 breast cancers treated in our institute, we found 61 lymphedema of the arm. We then describe our study population and identify by univariate et multivariate analysis the factors significantly associated to the disease. The majority of the patients were young black African female found to have locally advanced breast cancers (88% of T3 et T4 UICC 1988), inflammatory diseases (46% of PEV 2 and 3 of Gustave ROUSSY Institute classification of inflammatory breast cancers). Ulceration is found in half of the patients, metastasis in 20%. The patients first underwent chemotherapy mainly with cyclophosphamide alone (56%). Only 59 patients (8%) had preoperative radiation. Surgery consisted mainly in modified radical mastectomy and lymph node dissection (95%). Residual disease is left in 50% of the cases. Only 35% had post-operative chemotherapy and 9% postoperative external beam radiation therapy. From that population, during the follow up, 61 patients were found to have postmastectomy lymphedema. The disease was asymptomatic in 60% of the cases and painful in 26%. 30% of all the patients spontaneously partially regressed. From univariate analysis we found 7 factors associated with lymphedema: The big size of the tumor (p = 0.005), clinically involved axillary lymph nodes (p = 0.001), metastatic disease (p = 0.0046), traditional or inadequate surgery out of the Institute (p = 0.001), lack of post-operative chemotherapy (p = 0.002), postoperative external beam radiations (p = 0.005), relapse (p = 0.002). From logistic regression analysis three independent factors were found: clinically involved axillary lymph nodes (p = 0.0267), metastasis (p = 0.0002) and local or regional relapse (p = 0.0405). In our practice we found that advanced disease, treated by traditional healers or surgery nurses who had relapsed after mastectomy and external beam radiations without chemotherapy have higher risks of lymphedema.
