Treatment of failed Sauvé-Kapandji procedures with a spherical ulnar head prosthesis.

Unlabelled: Radioulnar convergence is a painful complication after a Sauvé-Kapandji procedure, with a reported incidence of 13% to 39%. We evaluated 10 patients with painful radioulnar convergence treated with a spherical ulnar head prosthesis proximal to the radioulnar fusion mass. At a mean follow-up of 2.

"Wrap around" pedicled muscle flaps for the treatment of recurrent forearm synostosis.

Three proximal and 2 mid shaft recurrent radioulnar synostoses were managed with a "wrap around" vascularized muscle interposition after excision of the heterotopic bone. A proximally pedicled brachioradialis flap was used for the proximal forearm and elbow synostoses, and the flexor carpi ulnaris muscle was used for the midshaft area. Anatomy of the flaps and the technical details of each procedure are thoroughly described.

Role of nitric oxide in vasodilation in upstream muscle during intermittent pneumatic compression.

This study investigated the dosage effects of nitric oxide synthase (NOS) inhibitor N(G)-monomethyl-L-arginine (L-NMMA) on intermittent pneumatic compression (IPC)-induced vasodilation in uncompressed upstream muscle and the effects of IPC on endothelial NOS (eNOS) expression in upstream muscle. After L-NMMA infusion, mean arterial pressure increased by 5% from baseline (99.5 +/- 18.

Effect of a NOS inhibitor, L-NMMA, on the contractile function of reperfused skeletal muscle.

The authors investigated the effect of NG-monomethyl-L-arginine acetate (L-NMMA), a nitric oxide synthase (NOS) inhibitor, on the contractile function of skeletal muscle following ischemia/reperfusion (I/R) injury. The extensor digitorum longus (EDL) muscles of 50 rats were divided into seven groups. Contractile function in non-ischemic EDL did not change statistically significantly with L-NMMA infusion.
