Product code LPH is FDA's classification for "Prosthesis, hip, semi-constrained, metal/polymer, porous uncemented" (orthopedic panel), a class 2 device. 90,251 medical device reports carry this product code, 0.4% of the MAUDE database, from July 1992 to August 2026.

5,784 reports arrived in the 12 months to August 2026, close to the 5,896 of the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (91.7%), malfunction (7.5%) and other (0.5%). 30 brand names with a page on this site carry this code; the brands table is ordered by report count for navigation only. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."

Questions about prosthesis, hip, semi-constrained, metal/polymer, porous uncemented reports

What is product code LPH?

FDA's classification code for "Prosthesis, hip, semi-constrained, metal/polymer, porous uncemented", class 2, reviewed by the orthopedic panel. Every device report carries the product code of the device involved.

How many reports carry this code?

90,251 reports through August 2026, 5,784 of them in the latest 12 months.

Which brands appear most often?

Unknown Hip Acetabular Liners (1,703), Unknown Hip Acetabular Cup (1,059), Apex Hole Elim Positive Stop (1,041), Pinn Can Bone Screw 6 5mmx25mm (955) and Unknown Hip Femoral Stem (883). Widely used products collect more reports because more people use them.

Can the brands table be used to rank the devices?

No. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data." Brands differ in how many are in use, how long they have been sold and how reports are collected.

Where this comes from. Counts are built from the openFDA Device Adverse Event (MAUDE) bulk export released 28 Sep 2026, which holds reports FDA received through 31 Aug 2026. Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
