Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Conservative observation with activity restriction
Initial management involves reducing weight-bearing activities to minimize stress on the affected bone. Regular imaging monitors disease progression and healing response.
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Core decompression or bone grafting
Surgical decompression of the necrotic area reduces intraosseous pressure and promotes revascularization. Bone grafting procedures provide structural support and stimulate healing in affected bone.
Additional treatment options
Bisphosphonate therapy
Medications that reduce bone resorption may help stabilize necrotic bone and prevent collapse. They are typically used as adjunctive therapy in conjunction with other treatments.
medicationGuided rehabilitation program
Structured physical therapy maintains joint mobility and prevents muscle atrophy during the healing phase. Progressive weight-bearing exercises are introduced as healing allows.
physical_therapyNutritional support for bone health
Adequate calcium and vitamin D intake supports bone healing and overall skeletal health. Weight management reduces mechanical stress on affected joints.
