Is unicompartmental-to-unicompartmental revision knee arthroplasty a reliable option? Case-control study.

BACKGROUND: In selected patients with failed unicompartmental knee arthroplasty (UKA), revision UKA is a reliable option and may even provide lower morbidity rates and better functional outcomes compared to revision total knee arthroplasty. MATERIAL AND METHODS: In a multicentre retrospective study of 425 knees requiring revision surgery after UKA, 36 knees were managed with revision UKA. RESULTS: Of the 36 knees, 3 (8.33%) required iterative revision surgery, for aseptic loosening. After a mean follow-up of 8.3 years, the mean IKS knee and function scores were high (93.81/100 and 90.77/100, respectively). DISCUSSION: In carefully selected patients, UKA-to-UKA revision performed according to a rigorous operative technique deserves a role in the surgical strategy for failed UKA. LEVEL OF EVIDENCE: III, multicentre retrospective case-control study.

Invasive recurrence of an intestinal-type mucinous epithelial neoplasm of low malignant potential: case report and review of the literature.

Pseudomyxoma peritonei is only rarely seen in conjunction with primary ovarian tumors. It has been suggested that only ruptured mucinous tumors arising in ovarian mature cystic teratomas can result in this clinical picture. We describe a case of a late invasive recurrence of a mucinous intestinal-type borderline ovarian tumor arising from a mature teratoma after complete surgical debulking. Borderline ovarian tumors behave indolently in the overwhelming majority of cases, and the prognosis is therefore usually outstanding.

Reliability of the Lagrange and Rigault classification system of supracondylar humerus extension fractures in children.

INTRODUCTION: The Lagrange and Rigault classification was designed to describe extension-type supracondylar fractures of the humerus. It can also help in treatment decision-making. HYPOTHESIS: The reliability of this classification has not yet been proven. The goal of this study was to assess this system's intra- and interobserver reliability. METHODS: One hundred supracondylar fracture radiographs were randomly retrieved and reviewed by five different observers on two occasions in a different order. The kappa index was used to calculate the intra- and interobserver reliability. RESULTS: Intraobserver reliability was 0.76 and interobserver reliability was 0.69. DISCUSSION: The study shows good intra- and interobserver reliability. The Lagrange and Rigault classification has similar reliability to other supracondylar fracture classifications.

Intramyometrial ectopic pregnancy in an ICSI patient following uterine artery embolization.

Myometrial pregnancy represents a rare subtype of ectopic pregnancy. A history of uterine artery embolization (UAE) because of symptomatic uterine fibroids, and assisted reproductive treatment may predispose to this unusual implantation site. A 40-year-old woman with a history of uterine fibroids underwent a transfer of two embryos after intracytoplasmic sperm injection treatment. The combined findings on transvaginal ultrasound scan, pelvic magnetic resonance imaging scan, suction curettage, diagnostic hysteroscopy and laparoscopy were compatible with a diagnosis of ectopic pregnancy within the myometrium, at the site of a necrotized intramyometrial fibroid following UAE. Treatment with systemic methotrexate resulted in successful resolution of this ectopic pregnancy. In conclusion, this study reports a pregnancy within a previously necrotized fibroid. Findings suggest that in patients with a history of UAE for the treatment of uterine fibroids and who subsequently undergo assisted reproductive treatment, the risk of an ectopic pregnancy within the myometrium has to be considered.

[False appearances of aortic arch in laryngomalacia (author's transl)]. / Faux aspects d'arc aortique au cours de la laryngomalacie.

The authors report six cases of congenital laryngeal stridor in which appearances of oesophageal compression had led to a diagnosis of abnormalities of the aortic arches. Two children underwent surgery, thoracotomy failing to reveal any abnormality. The other four were investigated by endoscopy which made it possible to eliminate the diagnosis of tracheal compression. All of these children were suffering from laryngomalacia. These cases indicate the need for complete routine studies, in particular endoscopic, in all cases of stridor, as well as for careful definition of the radiological criteria of abnormality of the aortic arches. The pathogenesis of these false appearances of oesophageal compression in laryngomalacia is discussed.
