Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to determine whether the Hyperbaric Oxygen Therapy (HBOT) conducted under the Marx Protocol improves pain outcomes when combined with core decompression with autologous bone marrow aspirate concentrate to treat patients with femoral head avascular necrosis.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

Participants with femoral head avascular necrosis having core decompression surgery using 3D modeling techniques with autologous bone marrow aspirate concentrate through the Yale Avascular Necrosis and Osteonecrosis Program. Participants will be able to choose which arm they wish to enroll in by participating in shared clinical decision making with the provider.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hyperbaric Oxygen Therapy- Full Marx Protocol

30 treatments before surgery, and 10 treatments after surgery

Group Type EXPERIMENTAL

Hyperbaric Oxygen Therapy

Intervention Type DEVICE

Sechrist Monoplace Hyperbaric Chamber Model 3600, Chamber will be used to supply patients with 100% oxygen to breathe at 2-2.4 ATA (the equivalent of diving to 33 - 45 feet of sea water) for two hours, 5 treatments per week

Hyperbaric Oxygen Therapy- Reduced Marx Protocol

20 treatments before surgery and 10 treatments after surgery

Group Type EXPERIMENTAL

Hyperbaric Oxygen Therapy

Intervention Type DEVICE

Sechrist Monoplace Hyperbaric Chamber Model 3600, Chamber will be used to supply patients with 100% oxygen to breathe at 2-2.4 ATA (the equivalent of diving to 33 - 45 feet of sea water) for two hours, 5 treatments per week

Control

No hyperbaric oxygen therapy

Group Type NO_INTERVENTION

No interventions assigned to this group

HBOT outside Yale

The participant is having HBOT sessions at a different location (outside of the Yale New Haven Health system). These treatments will be overseen by the outside facility's HBOT Director and completed according to the Marx protocol . The patient is responsible for picking a site, setting up their intake appointments, and going to the treatments. The patient is also responsible for providing the HBOT site Director with our protocol as well as returning a completed form that indicates that the proper protocol was used.
