Is Swanson prosthesis better than Sutter prosthesis for metacarpophalangeal joint arthroplasty? A meta-analysis

Abstract

The aim of this meta-analysis is to compare the outcomes of the Swanson and Sutter prostheses (previously the Avanta prosthesis) used for metacarpophalangeal joint arthroplasty, and provide a powerful and rational conclusion regarding the use of prosthesis in MCP joint surgery. The literature search was based on PubMed, Cochrane Library, MEDLINE, EMBASE, and the Chinese National Knowledge Infrastructure. Data were evaluated using a generic evaluation tool designed by the Cochrane Bone, Joint, and Muscle Trauma Group and analysed using RevMan, version 5.0. Six randomised controlled trials were contained in this review, and five of them involving 143 patients were included in the meta-analysis. The results suggested that using the Sutter prosthesis could significantly decrease the rates of recurrence of drift when compared with the Swanson prosthesis for metacarpophalangeal joint arthroplasty (OR = 2.05, 95% Confidence interval (CI) = 1.31-3.20, p = 0.002). No significant difference in the outcomes of prosthesis fracture was found in two groups (OR = 1.07, 95% CI = 0.41-2.79, p = 0.88). Due to the limited data, the outcomes of range of motion, correction of ulnar deviation, pain, grip strength, and radiographic osteolytic changes could not be included in the meta-analyses. Theoretically, recurrence of drift was more common with Swanson prosthesis when compared with the Sutter prosthesis. No significant difference in the outcomes of prosthesis fracture was observed in two groups. More high-quality studies are required in long-term follow-up.

Arthroplasty for Treating Traumatic Metacarpophalangeal Joint Defects: A Retrospective Study Over Three Years

“…However, there are some conservative arguments, given the high risk of implant fractures and infections. 9,21 We conducted a statistical analysis of the patients with implant fractures and found that Group A had worse radioulnar movement than Group B. There were no significant differences in the functional score between the two groups at postoperation.…”

Problematic Issues of the Theory and Practice of Finger Joints Endoprosthetics (Literature Review)

“…Усі нероз'ємні однокомпонентні силіконові протези, які створені за концепцією Swanson, працюють як гнучка розпірна деталь внаслідок вільного ковзання ніжок у кістковомозкових каналах і фіксації з формуванням фіброзної капсули навколо імплантату. За таких умов навантаження в системі "імплант ат -кістка" передається поздовжньо і концентрується в центральній частині ніжки [18].…”

“…И R. Beckenbaugh [13], и C. Hagert [21] сообщили о высокой частоте переломов этих моделей, предположив, что протез недостаточно прочен, чтобы противостоять испытываемым пациентом нагрузкам. В 1987 г. была представлена модель Sutter, созданная с целью устранить или хотя бы уменьшить недостатки модели Swanson [22][23][24]. В этом протезе использовался силикон «силфлекс».…”
