TY  - JOUR
AB  - Purpose: Studies have shown the effects of surgical treatments for trapeziometacarpal osteoarthritis on thumb biomechanics; however,  the biomechanical  effects  on  the wrist have  not  been  reported. This  study aimed to quantifyalterations  in  wrist  muscle  forces  following trapeziectomy with  or  withoutligament reconstruction and replacement. Methods: A  validated  physiological  wrist  simulator  replicatedcyclic  wrist  motions  in  cadaveric  specimens by applying tensile loads to six muscles. Muscle forces required to move the intact wrist were compared to   those required after   performing   trapeziectomy,   suture   suspension   arthroplasty,   prosthetic replacement and ligament reconstruction with tendon interposition (LRTI). Results: Trapeziectomy requiredhigher abductor pollicis longusforcesinflexion, and higher flex or carpi radialis forces coupled  with lower extensor  carpi  ulnaris forces in  radial  deviation. Of  the three  surgical reconstructions  tested  post-trapeziectomy, wrist  muscle  forces  following LRTI were closest to  those observed in the intact case, throughout the range of all simulated motions. Conclusions: This study shows that wrist biomechanics weresignificantly altered following trapeziectomy, and of the reconstructions tested, LRTI most closely resembled the intact biomechanics in this cadaveric model.
