Moore type hip prosthesis, which consists of a cobalt chromium hip prosthesis in a sealed plastic bag; the prosthesis consists of a steel spherical head and a triangular metal arm, with two fenestrations at its wide end, extending from the bottom of the sphere; the top half of the sphere is reflective, while the other surfaces are dull in appearance; there is a round hole running through the corner of the triangular arm where it is joined to the sphere; there is a spherical plastic covering on the head of the prosthesis; the narrow end of the arm ends with a rounded point; the prosthesis is sealed inside a clear plastic bag, along with a rectangular paper insert; the bag is closed with a folded piece of paper and a staple.
Based on printed information at bottom of the outside label.
On one side of the stapled folded paper sealing the plastic bag, blue printing reads: "VITALLIUM® // SURGICAL APPLIANCES // [logo]® // THE SYMBOL OF FINEST SURGICAL QUALITY // HOWMET [with a line design around the word resembling an elongated "H"] HOWMET CORPORATION // MEDICAL DIVISION // MADE IN U.S.A."; on the reverse side, blue printing reads, "VITALLIUM® // SURGICAL APPLIANCES // HIP PROSTHESIS // MOORE TYPE // Cat. No. 6939 // Head Diam. 1½ [underlined ] Quan. 1 // Xray Inspected"; the "1½" is handwritten in blue ballpoint pen; the inner surface of the paper reads, in blue printing, "You may rely on VITALLIUM® Surgical Appliances for high corrosion resistance // and maximum compatibility with human tissue. They are carefully manufactured // with the highest quality materials and workmanship, and are thoroughly in- // spected. // Since body dimensions limit the size of prosthesis use for [illeg.] // each VITALLIUM appliance is designed and [illeg.] // surgeon should select the type and [illeg.] // the individual case. // [illeg.] . The stem should not be bent or contoured. // . The prosthesis should be protected from scratching or damage — it // should not be hammered upon, directly. // . All internal appliances are expendable and never should be re-used. Any // metal appliance, once used, even though it appears satisfactory, may in // fact be damaged from previous use. // IMPORTANT [underlined] // For the personal attention of the operating surgeon // Printed 3-67"; the inner insert reads, in blue printing, "SUGGESTIONS FOR USE OF // ORTHOPEDIC APPLIANCES WITHIN THE BODY // [illeg.] // 1. The correct selection of [illeg.] is extremely important. [all underlined] // The potential for success in fracture fixation and bone re- // placement is increased by the proper selection of size, shape // and design of the implant. Since body dimensions limit the // size of appliances used for internal application, each VITAL- // LIUM appliance was designed and manufactured with this // in mind. This appliance was manufactured in accordance with // the originator's specifications and meets the requirements // for which it was designed and intended. // Fixation appliances [underlined] are not intended to withstand the stresses // of weight-bearing or excessive muscular activity, especially // in the case of delayed union or in the presence of an un-united // fracture. // In the case of bone replacement appliances [underlined from "bone"], selection of the // proper type and size is important. In addition, care must be // given to provide firm seating and adequate bone support for // best results. Prosthesis should be restricted to limited func- // tional stress. // 2. The correct handling of the appliance is extremely important. [underlined] // Contouring of metal appliances is to be avoided whenever // possible. If it is necessary to contour an appliance, it should // not be bent sharply or reverse bent. Care should be taken not // to nick or scratch the surface since such surface irregularities // can serve as points of stress concentration which could pos- // sibly lead to failure. // 3. No metallic surgical implant should be re-used [all underlined]. Any metal // implant once used should be discarded. Even though it appears // undamaged, it may in fact be damaged from previous use. // 4. Postoperative care is important [all underlined]. The patient should be in- // structed carefully in the limitations of his metallic implant // and should be cautioned regarding premature weight bearing // and body stresses on the appliance prior to secure bone heal- // ing. It is recommended that such instructions be supplied in // written form. // HOWMET // CORPORATION [these two words sitting on a drawn-out horizontal "H"] // AUSTENAL MEDICAL DIVISION // Printed 12-65"; in addition, "1½ VITALLIUM" is stamped into the metal of the side of the trangular arm, and "CC5847" is etched into the metal at the base of the head; "AUSTENAL AUTOCLAVABLE 1½ NOT IMPLANTABLE" appears in raised plastic lettering.

The paper insert and label were yellowing and there was a small hole in one side of the plastic bag; the metal components showed no signs of corrosion, and were unused; there were white marks over approximately 50% of the plastic head protector.
