简要总结

The objective of this study is to evaluate the bone ingrowth after implantation of the study device. This study will also document any device-related surgical complications or adverse radiographic observations. Improvement in pain, function, and health economic data will be compared with improvements documented with other joint systems.

详细描述

The purpose of the current investigation is to assess the bone ingrowth after implantation with a modular, short hip stem using Dual Energy X-ray Absorptiometry (DEXA). The intended use of this product is for patients with non-inflammatory and inflammatory degenerative joint disease who require a primary total hip replacement.

接受健康志愿者

入选标准

  • Patient has hip disease that requires a total hip arthroplasty.
  • Patient is willing to consent to participate in the study.
  • Patient plans to be available for the study duration.
  • Patient is in stable health and is free of or treated and stabilized for cardiac, pulmonary, hematological, or other conditions that would pose excessive operative risk.

排除标准

  • Patient known to have insufficient bone stock.
  • Patient has had major non-arthroscopic surgery to the study hip.
  • Patient has physical, emotional or neurological conditions that would compromise the patient's compliance with postoperative rehabilitation and follow-up.
  • Patient has a known sensitivity to materials in the device.

结局指标

主要结局

DEXA Analysis of BMD at Preoperative Visit

时间窗: Preoperative

DEXA=Dual Energy X-Ray Absorptiometry; BMD=Bone Mineral Density; The proximal femur was divided into 7 regions relative to the length of the stem. Lateral portions = region 1, region 2 and region 3; The entire bone mass immediately distal to the stem tip = region 4; Medial portions = region 5, region 6, and region 7. Mean BMD was calculated for each femoral region. BMD values were adjusted peri-prosthetically to account for stem area.

DEXA Analysis of BMD at 6 Months

时间窗: 6 Months

DEXA=Dual Energy X-Ray Absorptiometry; BMD=Bone Mineral Density; The proximal femur was divided into 7 regions relative to the length of the stem. Lateral portions = region 1, region 2 and region 3; The entire bone mass immediately distal to the stem tip = region 4; Medial portions = region 5, region 6, and region 7. Mean BMD was calculated for each femoral region. BMD values were adjusted peri-prosthetically to account for stem area.

DEXA Analysis of BMD at 1 Year

时间窗: 1 Year

DEXA=Dual Energy X-Ray Absorptiometry; BMD=Bone Mineral Density; The proximal femur was divided into 7 regions relative to the length of the stem. Lateral portions = region 1, region 2 and region 3; The entire bone mass immediately distal to the stem tip = region 4; Medial portions = region 5, region 6, and region 7. Mean BMD was calculated for each femoral region. BMD values were adjusted peri-prosthetically to account for stem area.

DEXA Analysis of BMD at 2 Years

时间窗: 2 Year

DEXA=Dual Energy X-Ray Absorptiometry; BMD=Bone Mineral Density; The proximal femur was divided into 7 regions relative to the length of the stem. Lateral portions = region 1, region 2 and region 3; The entire bone mass immediately distal to the stem tip = region 4; Medial portions = region 5, region 6, and region 7. Mean BMD was calculated for each femoral region. BMD values were adjusted peri-prosthetically to account for stem area.

DEXA Analysis of BMD at 3 Months

时间窗: 3 Months

DEXA=Dual Energy X-Ray Absorptiometry; BMD=Bone Mineral Density; The proximal femur was divided into 7 regions relative to the length of the stem. Lateral portions = region 1, region 2 and region 3; The entire bone mass immediately distal to the stem tip = region 4; Medial portions = region 5, region 6, and region 7. Mean BMD was calculated for each femoral region. BMD values were adjusted peri-prosthetically to account for stem area.
