Insights
Young patients with hip osteonecrosis (ON) showed improved mobility and gait after core decompression surgery. This procedure helps prevent femoral head collapse and the need for future hip replacements.
Area of Science:
- Orthopedics
- Pediatric Hematology/Oncology
- Rehabilitation Medicine
Background:
- Osteonecrosis (ON) of the hip affects young patients with leukemia and sickle cell disease, leading to pain and disability.
- Hip core decompression surgery is a potential intervention to prevent femoral head collapse and the need for future arthroplasty.
Purpose of the Study:
- To evaluate functional outcomes and gait quality in young patients with hip ON before and after core decompression surgery.
Main Methods:
- Included 13 participants (8-29 years old) with hip ON secondary to hematologic malignancy or sickle cell disease.
- Assessed functional mobility (Functional Mobility Assessment - FMA), range of motion, and gait quality (GAITRite®) at one-year follow-up.
Main Results:
- Participants showed significant improvements in FMA scores for Timed Up and Go, Timed Up and Down Stairs, and 9-Minute Walk Test at one year post-surgery.
- GAITRite® analysis indicated improvements in multiple gait parameters compared to pre-operative assessments.
Conclusions:
- Hip core decompression surgery led to enhanced functional mobility, endurance, and gait quality in young patients with hip ON one year post-operatively.
Background:
Patients with pediatric leukemia and sickle cell disease are at risk for developing osteonecrosis (ON), a disease that can result in pain, loss of function, and disability. Hip core decompression surgery is an option aimed to prevent femoral head collapse and avoid future arthroplasty.
Objective:
Describe functional outcomes and gait quality among a young population with hip ON before and after hip core decompression.
Methods:
Study included participants with hip ON secondary to treatment for hematologic malignancy or sickle cell disease, between 8 and 29 years old, requiring hip core decompression surgery. At one-year follow-up, 13 participants (9 male, median age 17 years) completed the Functional Mobility Assessment (FMA), range of motion, and GAITRite® testing.
Results:
Participants demonstrated improved mobility and endurance on the FMA at 1-year post-operatively compared to pre-operatively, with higher scores for time on the Timed Up and Go (mean FMA score = 2.92 [SD = 1.32] vs. 2.07 [SD = 1.70]), time on the Timed Up and Down Stairs (3.69 [0.85] vs. 2.92 [1.66]), and 9-Minute Walk Test scores for distance walked (2.69 [0.63] vs. 2.23 [0.93]) and heart rate (4.54 [0.66] vs. 3.31 [1.38]). GAITRite® analysis also showed improvements in many gait parameters at one-year follow-up.
Limitations:
Cancer treatment complications other than ON could have contributed to results, not all eligible participants agreed to participate, and follow-up was only one year.
Conclusions:
Young patients with hip ON demonstrated improvements in functional mobility, endurance, and gait quality one year following hip core decompression.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
