Comparison of survival between cemented vs cementless unicompartimental knee arthroplasty: a case control study with propensity score matching.

Introduction: The first results of cementless prosthesis were rather disappointing. However recent progress in methods of cementless fixation of prosthesis should lead to better results in terms of survival of these prostheses. The main objective is to compare the survival rate at last follow-up of UKA with cemented tibial or cementless.

Accuracy of Preoperative 3D vs 2D Digital Templating for Cementless Total Hip Arthroplasty Using a Direct Anterior Approach.

Background: An important aspect of preoperative planning for total hip arthroplasty is templating. Although two-dimensional (2D) templating remains the gold standard, computerized tomography (CT)-based three-dimensional (3D) templating is a novel preoperative planning technique. This study aims to compare the accuracy of a 2D and 3D plan using an anterior approach for the placement of the same uncemented prosthesis.

Revision total hip arthroplasty by a ceramic bearing surface after a third- and fourth-generation ceramic head or liner fracture.

Purpose: Although rare, fractures of ceramic components are difficult to revise, mainly due to the presence of residual ceramic debris that can cause catastrophic wear of the replacement components. Modern ceramic-on-ceramic bearings are suggested to improve outcomes of revision total hip arthroplasty (THA) for ceramic fractures. However, there are few published reports of mid-term outcomes of revision THA using ceramic-on-ceramic bearings.

Systematic alignments yield balanced knees without additional releases in only 11% of knee arthroplasties: a prospective study.

Purpose: The literature suggests that "forgotten" knees are the most stable knees postoperatively. The main objective of our study was to determine whether a systematic alignment (mechanical, anatomical or kinematic) makes it possible to stabilise the operated joint in extension and in flexion.

Methods: This monocentric prospective cohort study was conducted between May 1st, 2021 and October 31st, 2021.

Haematogenous prosthetic knee infections: Prospective cohort study of 58 patients.

Background: Prosthetic joint infection (PJI) is a rare (incidence, 0.15% to 0.9%) but serious complication of knee arthroplasty.

Patient's satisfaction after outpatient forefoot surgery: Study of 619 cases.

Introduction: The number of outpatient surgical procedures performed in France on the forefoot has grown rapidly in recent years.

Objectives: The goal of this study was to evaluate experience and satisfaction of patients undergoing outpatient foot surgery using a telephone questionnaire developed for this purpose.

Material And Methods: In 2012 and 2013, every patient who was admitted to the day surgery unit at our hospital for an open procedure on their forefoot was called the morning after the procedure.

Doctor, what does my knee arthroplasty weigh?

The aim of this study was to compare the weight of the total knee arthroplasty (TKA) implants and the weight of the natural knee. A prospective study was conducted with two different brands of cemented primary TKA. During the procedure, we collected the removed bone, soft tissues and the post-implantation cement and weighed them all separately at the end.

[Pyogenic liver abscesses].

Background: Pyogenic liver abscesses were a relative rare disease. In the last decades the management of the liver abscesses was changed due to the new imaging and surgical techniques.

Aim: To evaluate the clinical features, imaging techniques and treatment of the liver abscesses.

Arthrodesis after failed total ankle replacement.

We present a series of 16 patients treated between 1993 and 2006 who had a failed total ankle replacement converted to an arthrodesis using bone grafting with internal fixation. We used tricortical autograft from the iliac crest to preserve the height of the ankle, the malleoli and the subtalar joint. A successful arthrodesis was achieved at a mean of three months (1.

[Cephalic duodenopancreatectomy with pyloric preservation in the treatment of pancreatic cancer].

Unlabelled: Is the application of DPCPP in the treatment of pancreatic neoplasia a good reason? We have analysed 30 patients with cephalic duodenopancreatectomy (DPC) for biliopancreatic neoplasia between 1995-1999 in Ist Surgical Clinic of Iassy (13 with pyloric preservation). The indications were:--cephalic pancreatic neoplasia (adenocarcinoma--4 cases (one with cephalic chronic pancreatitis on the intraoperative microscopical examination);--Vater ampulloma (7 cases);--inferior common biliary duct (CBD 1 case);--duodenal adenocarcinoma (1 case). In the same time was operated 265 biliopancreatic diseases (203 mechanical jaundice with 132 neoplastic jaundice).

Nanostructured Silica-Based Organic-Inorganic Hybrid Materials-Evidence for Self-Organization of a Xerogel Prepared by Sol-Gel Polymerization.

A hydrolytic polycondensation reaction of a rigid, rodlike nonmesomorphous precursor leads to an isotropic sol and then an anisotropic birefringent xerogel (see scheme). Optical and X-ray structural analyses demonstrate a short-range order and the possibility of a crystalline order.

[The Wermer syndrome].

The difficult diagnostic and therapeutic management of patients having gastrinoma with multiple endocrine neoplasia type I (MEN I) has been discussed by reference to the literature and a personal experience of 2 patients with Wermer syndrome. The syndrome is often familial and might be inherited as an autosomal dominant trait with a high but variable degree of penetrance. Pancreatic islets, parathyroid glands and adenohypophyseal [correction of antehypophyseal] cells are the three localization main for endocrine involvement in MEN I syndrome.

[Choledochal cyst in adults and cancer of the biliary tract].

We presented 3 cases of cystic dilatation of common bile duct classified as type IC, IVB an IVA. All 3 were women, admitted for right upper quadrant pain and jaundice. Two cases proved malignant degeneration in cystic dilatation in first cas and in gallbladder in third.

[Malignant tumors of the digestive tract below the diaphragm in young people].

We have retrospectively studied 1243 malignancies of the infradiaphragmatic tract treated in the First Surgical Clinic between 1978-1994 (678 gastric, 300 rectal and 256 colonic malignancies). Out of these 39 cases have been encountered in young patients (14 gastric, 13 colon and 12 rectal malignancies). The following particularities have been noted in this group: hereditary predisposition, more advanced stage at diagnosis, predominance of non-Hodgkin lymphomas and poorly differentiated forms.

[Thyroid cancers].

We have analysed factors that influenced on the patient survival in 195 cases of thyroid cancer. The survival is essentially influenced by the histology, the papillary forms (survival after 15 years: 83.1-93%) and follicular cancers (survival after 15 years: 84-94%) having an excellent evolution.

[Mechanical anastomoses in esophagogastric surgery for malignant tumors].

The authors present their experience in employing for the first time the mechanical circular suture with I.L.S.

[The cardiac manifestations in hyperthyroidism. The surgical implications].

In a statistics including 954 patients with hyperthyroidism [correction of Huprotoncoses] treated between 1966-1989, the authors found 522 cases (54) with various associated cardiac disorders. Of these cases, 199 presented rhythm disturbances: extrasystolic arrhythmia, auricular fibrillation and flutter to which 34 postoperative arrhythmias are added. Cardiac insufficiency present in 46 cases was the main complication and end point of the various myocardial conditions.

[The hyperfunctional thyroid nodule].

Authors report their experience of 22 years regarding 284 patients with hyperfunctional thyroidal nodules (279 operated), representing 12.4% of the 2,289 cases of thyroidal (875 hyperthyroid) diseases treated during this period. The diagnosis was established on the basis of the confrontation of the anamnestic symptomatology and of that found at the clinical examination--which confirmed the pure character of thyrotoxicosis by showing the presence of a thyroidal nodule--with the study of the global glandular function and the scintigram, completed with dynamic tests.

[The value and limits of subtotal gastrectomy in gastric cancer].

In the interval 1970-1988, in 321 of 670 patients with gastric neoplasm admitted to the 1st Surgical Clinic of Iaşi a subtotal gastrectomy was performed. Most patients were males (68.9%), more commonly aged between 50 and 70 years and in advanced evolutive stages.

[The "cold" thyroid nodule].

The main problem posed by an (apparent) solitary thyroid nodule is cancer identification, present in about 10% of the nodules excised surgically. This percent might increase to 25-30% in the cold scintigraphic nodules. Therefore, a combination of all the methods for nodule assessment is necessary: anamnesis, physical examination, functional tests, therapeutic test with tyrosine and thyroid imaging, but mainly the intensive active exploration including puncture-biopsy with a fine needle and exeresis with extemporaneous and paraffin morphological checking.
