Clyde Evans Parker, federal inmate # 34006-177, appeals the dismissal of a civil rights complaint alleging that, during his incarceration as a pre-trial detainee, the defendants failed to provide constitutionally adequate medical treatment for his broken arm. Parker also appeals denial of a post-judgment motion for relief under Fed.R.Civ.P. 59(e), and he moves for appointment of appellate counsel and permission to supplement the record.

The district court concluded that Parker’s complaint failed to state a claim for relief and granted Fed.R.Civ.P. 12(b)(6) relief as to all defendants. Parker does not challenge the district court’s determination that he failed to state a claim against defendants John Peter Smith Hospital, Anderson, Simon, Hendrix, Ferrell, Murphy, Clements, Mitchell and Washington. Accordingly, he has abandoned his claims against these defendants. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993).

The grant of a motion to dismiss pursuant to Rule 12(b)(6) is reviewed de novo, *461 with all well-pleaded facts accepted as true and viewed in the light most favorable to the plaintiff. In re Katrina Canal Breaches Litigation, 495 F.3d 191, 205 (5th Cir. 2007), ce rt. denied, — U.S. -, 128 S.Ct. 1230, 170 L.Ed.2d 63, and cert. denied, - U.S. -, 128 S.Ct. 1231, 170 L.Ed.2d 63 (2008). Parker’s claims against defendants Wroten, Blair, Junias, Ampelas, and Butterfield allege, at most, negligence or malpractice; thus, the district court did not err by concluding that Parker failed to state a claim of constitutionally inadequate medical treatment. See Gobert v. Caldwell, 463 F.3d 339, 346 (5th Cir. 2006); In re Katrina Canal, 495 F.3d at 205. As Parker does not challenge the denial of his post-judgment motion to amend, we conclude that he has also abandoned this issue. Yohey, 985 F.2d at 224-25. Consequently, the judgment of the district court is AFFIRMED and the motions for appointment of counsel and to supplement the record are DENIED.
