Background:Primary total elbow arthroplasty (TEA) is a challenging procedure for orthopedic surgeons. It is not performed as frequently as compared to hip or knee arthroplasty. The elbow is a nonweight-bearing joint; however, static loading can create forces up to three times the body weight and dynamic loading up to six times. For elderly patients with deformity and ankylosis of the elbow due to posttraumatic arthritis or rheumatoid arthritis or comminuted fracture distal humerus, arthroplasty is one of the option. The aim of this study is to analyze the role of primary total elbow arthroplasty in cases of crippling deformity of elbow.Materials and Methods:We analyzed 11 cases of TEA, between December 2002 and September 2012. There were 8 females and 3 males. The average age was 40 years (range 30-69 years). The indications for TEA were rheumatoid arthritis, comminuted fracture distal humerus with intraarticular extension, and posttraumatic bony ankylosis of elbow joint. The Baksi sloppy (semi constrained) hinge elbow prosthesis was used. Clinico-radiological followup was done at 1 month, 3 months, 6 months, 1 year, and then yearly basis.Results:In the present study, average supination was 70° (range 60-80°) and average pronation was 70° (range 60-80°). Average flexion was 135° (range 130-135°). However, in 5 cases, there was loss of 15 to 35° (average 25°) of extension (45°) out of 11 cases. The mean Mayo elbow performance score was 95.4 points (range 70-100). Arm length discrepancy was only in four patients which was 36% out of 11 cases. Clinico-radiologically all the elbows were stable except in one case and no immediate postoperative complication was noted. Radiolucency or loosening of ulnar stem was seen in 2 cases (18%) out of 11 cases, in 1 case it was noted after 5 years and in another after 10 years. In second case, revision arthroplasty was done, in which only ulnar hinge section, hinge screw and lock screw with hexagonal head were replaced.Conclusion:Elbow arthroplasty remains a valuable option for deformed and ankylosed elbows especially in the demanding patients with crippling deformity of the elbow.

“…Schmidt et. al [ 2 ]. kommen auch zu dem Ergebnis, dass die gekoppelte Prothese (GSB III, Coonrad-Morrey) Vorteile gegenüber der ungekoppelten (Souter-Strathclyde) bieten, vor allem durch die Gelenkstabilität und die längeren humeralen Stiele.…”

Ellenbogengelenkersatz – gekoppelt oder nicht gekoppelt?*

Zusammenfassung Die Endoprothesen f?r das Ellenbogengelenk folgen unterschiedlichen Bauweisen und Kon?struktionsprinzipien. Die Frage des notwendigen Kopplungsgrades wird nach wie vor kontrovers diskutiert. Sloppy-hinge-Kopplungen haben starre Scharnierkopplungen abgel?st. W?hrend ungekoppelte Prothesen die Gefahr der Luxation und der Instabilit?t bergen, wird f?r die sloppy-hinge-Prothesen eine fr?hzeitigere mechanische Lockerung bef?rchtet. Aktuelle vergleichende Studien liefern keine sicheren Anhaltspunkte daf?r, dass diese Bef?rchtungen berechtigt sind.
