Article: Evaluation of postoperative fever and leukocytosis in patients after total hip and knee arthroplasty.
[show abstract] [hide abstract]
ABSTRACT: Fever and leukocytosis are common after joint arthroplasty, often resulting in additional studies. This study was conducted to determine the incidence of fever and leukocytosis after joint arthroplasty and the use of tests. We retrospectively reviewed records (n = 426) of patients who underwent knee or hip arthroplasty between February 2006 and April 2008 to determine the incidence of fever and leukocytosis, tests, and results. Sixty-four had fever, and 247 had postoperative leukocytosis. Sixty additional tests were performed; 6 (10%) of 60 tests were clinically relevant. After joint arthroplasty, more than half of patients developed leukocytosis, and nearly 15% developed fever. Diagnostic testing should be based on physical examination or symptomatic findings and not solely on laboratory values or vital signs, decreasing the patient discomfort and potentially lower costs.The Journal of arthroplasty 02/2011; 26(8):1387-9. · 1.79 Impact Factor -
Article: The incidence of femoral component version change in primary THA using the S-ROM femoral component.
[show abstract] [hide abstract]
ABSTRACT: Although use of modular femoral components in revision total hip arthroplasty (THA) is widely accepted, many still question the need for modular versatility in primary THA. This study examined a large cohort of primary THA patients implanted with a modular S-ROM femoral component (DePuy Orthopaedics, Warsaw, Indiana) to determine the percentage of hips in which the surgeon changed version of the femoral component to increase the intraoperative stability of the THA construct and/or to maximize hip range of motion without impingement.In a group of 1000 routine, primary THAs, femoral component version was changed in 479 hips (47.9%). This change in rotational position of the femoral stem ranged from 60° retroversion with respect to the position of the sleeve to 80° of anteversion with respect to the sleeve. Ten hips (1%) experienced dislocation within the first 3 postoperative months. There was no difference in the dislocation rate between those patients in which femoral component version was changed versus those in which version was not changed. Statistical analysis showed no correlation between the likelihood of changing stem version and any of the following clinical variables: patient age, sex, diagnosis, or surgeon.The high percentage of straightforward primary THAs in which it was deemed beneficial to change version of the stem combined with the lack of correlation between femoral version change and clinical variables leads us to conclude that the routine use of a stem that allows variable version may be advantageous when compared to a nonmodular stem, as it is not possible to preoperatively determine when changing version will be required.Orthopedics 01/2011; 34(4). · 2.66 Impact Factor -
Article: S-ROM hip prosthesis: 10- to 14-year results.
[show abstract] [hide abstract]
ABSTRACT: This retrospective study evaluated the results of 55 S-ROM femoral components (45 patients) at 10 to 14 years postoperatively. Twelve patients (15 hips) were lost to follow-up. Survivorship of the prosthesis was determined in the remaining 33 patients (40 hips). Harris hip scores and radiographic analyses were performed. Thirty-four hips were performed in a primary fashion and 6 for revision arthroplasty. There was 100% survival for aseptic loosening in the primary arthroplasty group and 1 failure in the revision group. This study shows excellent long-term results of the S-ROM prosthesis at 10 to 14 years.Orthopedics 04/2008; 31(3):220. · 2.66 Impact Factor
