Backup kit for a patient-specific arthroplasty kit assembly
First Claim
1. A backup system for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility for a plurality of different patients comprising:
- a plurality of implants selected and assembled for a shipment of a plurality of patient-specific arthroplasty systems for the medical facility, the plurality of patient-specific arthroplasty systems configured for corresponding arthroplasty procedures at the same medical facility for a planned period of time, at least one of the plurality of patient-specific arthroplasty systems having one or more of the plurality of implants with a size that differs from a planned size of another of the plurality of backup implants that are part of the plurality of patient-specific arthroplasty systems, a number and sizes of at least one of the plurality of implants determined from a statistically expected implant size deviation from a planned implant size in the plurality of patient-specific arthroplasty systems using a database having data from completed arthroplasty procedures with other patient-specific arthroplasty systems, the database including comparisons between preoperatively planned implant sizes and intraoperatively implanted implant sizes.

Abstract
A method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.

8. A backup system for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility for a plurality of different patients comprising:
-
a database of data from completed arthroplasty procedures using prior used patient-specific arthroplasty systems, information collected and provided by the database including comparisons between a plurality of preoperatively planned implant sizes and a plurality of intraoperatively implanted implant sizes, the database being updated after the patient-specific arthroplasty procedures are performed and depending upon the characteristics of implants and instruments used in the plurality of patient-specific arthroplasty procedures; an omnibus backup system of backup implants assembled for the shipment by accessing and referencing the database, wherein the omnibus backup system includes a plurality of patient-specific arthroplasty systems; and a computer configured to determine a statistically expected implant size deviation from a planned implant size for each implant included in the plurality of patient-specific arthroplasty systems for the plurality of different patients that form the omnibus backup system during a planned time period prepared for a shipment to the medical facility using the database, the computer determining of the statistically expected implant size deviation being performed utilizing algorithms for statistical analysis; wherein a number and size of the backup implants are determined from the statistically expected implant size deviations and a number of implants corresponding to the planned implant size based on the totality of procedures for the plurality of different patients during the planned time period. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
