Arkansas prisoner Bobby McReynolds appeals the district court’s 1 order dismissing his 42 U.S.C. § 1983 action after a pretrial evidentiary hearing. McReynolds claimed that defendants showed deliberate indifference to his medical needs by neglecting to schedule and take him to a post-hernia-surgery follow-up appointment, and by placing him on a top bunk after his surgery contrary to medical orders for a lower bunk assignment. In dismissing McReynolds’s complaint, the court relied in part on the absence of harm caused by the missed appointment, and on McReynolds’s failure to show that any defendant was personally responsible for any unconstitutional action. Following careful review, see Johnson v. Bi-State Justice Ctr., 12 F.3d 133, 135-36 (8th Cir. 1993) (standard of review), we affirm. See 8th Cir. R. 47B.
