Carl Anthony Duperon, Louisiana prisoner # 101335, appeals from the district court’s order dismissing his pro se 42 U.S.C. § 1983 civil rights action as frivolous and for failure to state a claim upon which relief may be granted, pursuant to 28 U.S.C. §§ 1915(e)(2)(B)© and (ii) and 1915A.

Duperon alleged that the defendants were deliberately indifferent to his serious medical needs when they housed him for 18 days in isolation, rather than in his prison’s medical ward, after he fractured his jaw and had his jaw wired shut; this allegedly led to a serious infection. The magistrate judge determined that Duper-on’s allegations and medical records showed that he was promptly and properly treated; that he was taken to a hospital almost immediately after the severity of the infection was discovered; that surgery for the fracture was performed days later; and that Duperon’s recovery following the surgery was uneventful. The magistrate judge concluded that, at worst, Duperon had stated a claim of negligence or mal *780 practice. In his appellate brief, Duperon has failed to make specific arguments with respect to his deliberate-indifference claims or to cite the portions of the record upon which he relies. Accordingly, we conclude that Duperon has effectively abandoned his claims, in that they are inadequately briefed. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993); Fed. R.App. P. 28(a)(9).

The appeal is without arguable merit, is frivolous, and is therefore dismissed. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5th Cir. R. 42.2. The district court’s dismissal of Duperon’s § 1983 complaint and the dismissal of this appeal as frivolous count as strikes under the three-strikes provision, 28 U.S.C. § 1915(g). See Adepegba v. Hammons, 103 F.3d 383, 387-88 (5th Cir. 1996). Duperon is cautioned that if he accumulates a third strike under 28 U.S.C. § 1915(g), he will not be permitted to proceed in forma pauperis in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See § 1915(g).

APPEAL DISMISSED; SANCTION WARNING ISSUED.
