Elbow stiffness is a common problem following trauma to the elbow. Sixty-seven patients with posttraumatic elbow stiffness were surgically treated between 1985 - 2000. Sixty-one were clinically reviewed after a mean follow-up of 15 years (range: 7 to 19 years). The initial trauma had resulted in 8 intrinsic, in 31 extrinsic and in 28 mixed lesions. The mean preoperative flexion – extension arc of motion, was 46°. After an unsuccessful conservative treatment, open surgical arthrolysis was performed in 59 patients with exclusively extrinsic or mixed lesions, through a lateral approach combined with a medial approach when deemed necessary. In patients with complex intrinsic lesions was performed 3 resection arthroplasty and 5 total elbow arthroplasty. At final follow-up, the mean arc of motion of the elbow was significantly improved to 100° in 56 patients who had undergone open arthrolysis; 3 were lost to follow-up. Among the 3 patients who had undergone arthroplasty resection, only one had a markedly improved elbow function with a 90° arc of motion; elbow stiffness had recurred in the other two patients. Of the 5 patients who underwent total elbow arthroplasty, 3 were lost to follow-up; the other 2 patients had a stable elbow, with a fair arc of motion of 60° and 70° respectively, both with a flexion contracture of 20°. Complications included 2 superficial infections, which healed following conservative treatment, and one fracture following remodeling of a malunited distal fracture of the humerus. In the treatment of the posttraumatic stiffness of the elbow, the arthrolysis and the arthroplasty are indicated in dependence on the existent (extrinsic or intrinsic) lesions and on their severity.
Összefoglaló. A felszínpótló, fém a fémen csípőízületi protézisek reneszánszukat élték a 2000-es években. Elsősorban fiatal, aktív betegek esetében javasolták használni a remélt elméleti előnyök, mint a combfej csontállományának megőrzése, a csípőízület biomechanikájának fenntartása, a luxatio kockázatának csökkentése, a polietilén törmelékek és kopástermékek hiánya miatt. Bemutatunk egy beteget, akinél 19 éves korában kétszeri vesetranszplantációt követő, hosszan tartó szteroidkezelés következtében kialakult kétoldali combfejnekrózis miatt került sor felszínpótló, fém a fémen csípőprotézis beültetésére. A harmadik posztoperatív évtől mindkét csípőt érintő, fokozatosan súlyosbodó fájdalom, pszichés tünetek, valamint ismételt veseelégtelenség alakult ki. A tünetek hátterében kifejezetten magas Co-Cr szérumszintet, a csípőízület környezetében pszeudotumor-kialakulást, kiterjedt acetabularis cystákat, a combnyakak jelentős elvékonyodását találtuk, mely jobb oldalon periprotetikus combnyaktörést okozott. A revíziós műtétek során talált kiterjedt szöveti metallosis eltávolítását követően a felszínpótló protéziseket cement nélküli kerámia–kerámia totális protézisekre cseréltük. A revíziókat követően a lokális és pszichés tünetek megszűntek, a szérum Co-Cr szintje normalizálódott, ami lehetővé tette a harmadik vesetranszplantáció elvégzését is. Páciensünk csípőrevíziókat követő gyors javulása közvetett bizonyítékként szolgál a Co-Cr ionok negatív szerepére mind a helyi, mind a szisztémás szöveti reakciókban, így a transzplantált vese károsodásában. Esetünk tanulságai, hogy szervtranszplantációt követően kerülni kell a fém a fémen protézisek használatát, valamint hogy nem elég a csípőízületi protézis indikációjának felállítása és a legmodernebbnek tartott protézis használata. Különös gonddal és elmélyülten kell elemezni a beteg járulékos körülményeit, gyógyszerelését, társbetegségeit is ahhoz, hogy a legmegfelelőbb típusú protézist tudjuk kiválasztani, ami nem megkerülhető felelőssége az ortopéd sebészeknek. Orv Hetil. 2021; 162(20): 800–805. Summary. The surface replacement, metal on metal hip prostheses, experienced a renaissance in the 2000s. It has been recommended for use primarily in young, active patients due to expected theoretical benefits such as preserving femoral bone stock, maintaining hip joint biomechanics, reducing the risk of dislocation, and lacking polyethylene debris abrasion products. We present a patient who had resurfacing prosthesis because of bilateral femoral head necrosis due to long-term steroid treatment following double kidney transplantation at the age of 19. In the third postoperative year, progressive pain in both hips, psychiatric symptoms, and recurrent renal failure developed. We found extremely high serum Co-Cr levels, pseudotumor formation of the hip joint, extensive acetabular cysts, and significant thinning of the femoral neck, followed by a periprosthetic femoral neck fracture on one side. After removing the extensive tissue metallosis found during the revision surgeries, the surface replacement prostheses were replaced with cementless ceramic–ceramic total prostheses. Following the revisions, local and psychiatric symptoms resolved, and serum Co-Cr levels normalized, allowing a third kidney transplant to be performed. The rapid improvement of our patient after prosthesis revisions serves as indirect evidence for the negative role of Co-Cr ions in both local and systemic tissue reactions, including damage to the transplanted kidney. Our case report shows that the use of metal on metal prostheses after organ transplantation should be avoided and simply setting up an indication for hip prosthesis and use the most modern type of prosthesis is inadequate. Depth analysis of the patient’s ancillary conditions, medications, co-morbidities are required to select the most appropriate prosthesis type, which is an unavoidable responsibility of orthopedic surgeons.

The authors report on 34 patients with a pelvic rim disruption who were treated with percutaneous 7.3 mm screws. This technique is less invasive and gives immediate comfort. Screws were placed with conventional fluoroscopic assistance. In four cases, the screw tip was protruding out of the pelvic bone, two malposition screws were in the back, and two were in the front of the pelvic ring. A revision was needed in one case. We also report on 20 elderly patients with a fracture dislocation of the hip that ran into the pelvis. Eight of them were anteromedial dislocations, and the rest were central dislocations of the femoral head. In the group of anteromedial fracture dislocations, the results were excellent, with an open reduction and internal fixation (ORIF) achieved through a retroperitoneal approach. In the subgroup of central fracture dislocations, we performed the same type of osteosynthesis via the retroperitoneal approach. However, we obtained an excellent result for only two cases. We have a couple of results. First, a percutaneous screw fixation for pelvic fractures with fluoroscopic guidance gives excellent results in most cases. Second, central fracture dislocations of the hip perform poorly after osteosynthesis via the retroperitoneal approach. These fractures probably should be offered acute or delayed total hip arthroplasty (THA).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
