maanden toonde een fusiepercentage van 91%. Er bleek geenverband tussen de radiografische en de klinische resultaten.Gezien de lage incidentie van verwikkelingen, de goede subjectievetevredenheid en de stabiele resultaten na een follow-up van 5 jaar,kan besloten worden dat monosegmentaire PLIF een waardevolle enveilige techniek is in de heelkundige behandeling van lage rugpijn.Symptomatische degeneratie van de aangrenzende lumbale niveausblijkt op deze termijn klinisch niet relevant te zijn.GOVAERS K., MEERMANS G., STUYCK J., DEPREZ P., BORTIER H.,ROELS J.: Endoscopy for cement removal in revision arthroplasty ofthe hip. J. Bone Joint Surg. (Am), 2006; 88(4): 101-109.One of the primary steps in revision hip arthroplasty is the extraction ofretained components and cement before surgical reconstruction. Inrevision hip arthroplasty, the removal of well-fixed cement can beextremely demanding, time-consuming, and damaging to theremaining host bone. A number of studies have shown the usefulnessof endoscopy of the medullary canal to facilitate cement removalwithout performing a trochanteric osteotomy. Various endoscopysystems have been designed to visualize the endosteal surface of thebone. Here we report on a multicenter prospective study on cementremoval with standard available endoscopy equipment in both infectedand uninfected hips undergoing revision arthroplasty. The aims of ourstudy were (1) to define the usefulness of and the quality of the viewprovided by standard available laparoscopic equipment, (2) to reporton intraoperative complications during medulloscopy-assisted cementremoval, (3) to define the risk factors for femoral perforation andintraoperative fracture, (4) to define the indications for and limitationsof medulloscopy for cement removal, and (5) to perform a criticalanalysis of the completeness of cement removal, especially inrevisions done in infected hips.HARDEMAN F., VANDENNEUCKER H., VANLAUWE J., BELLEMANS J.:Cementless total knee arthroplasty with Profix: a 8- to 10- year followupstudy. The Knee, 2006; 13: 419-421.A consecutive series of 115 cementless Profix (Smith and Nephew,Memphis, USA) Total Knee Arthroplasties performed in 113 patientswere followed in order to determine the functional results andsurvivorship at 8 to 10 years. All patients were included in aprospective database and were reviewed annually until final followup.Patients overall satisfaction was excellent or good in 91,3% of59
