Thirty-four patients had radiographic findings of contralateral AVN at study entry; 25 were symptomatic bilaterally at entry and 7 developed contralateral symptoms within a mean time of 12 months median 10 months, interquartile range 12 months.

None of the 13 patients who were free of radiographic evidence of contralateral AVN at study entry developed evidence of AVN during the follow-up. Radiographically-evident AVN in the contralateral hip at THA is unlikely to remain asymptomatic for a prolonged period of time.

Conversely, asymptomatic contralateral hips without radiographic evidence of AVN are unlikely to develop clinically significant AVN. CT scanning may help delineate early subchondral collapse necrosis de cadera the resolution of bony architecture with this modality is unsurpassed.

Angiography is an invasive mean of diagnostic confirmation of AVN; it is most useful as an investigational modality. Restricted patient weight bearing with the use of a cane or crutches has not been shown to affect the natural history of the disease and is useful only in controlling symptoms.

Necrosis de cadera therapy necrosis de cadera only symptomatic control and also does little to alter disease progression. Patient referral to social services, psychologic or psychiatric counseling, or community outreach is recommended.

For patients with prolonged steroid use, osteoporosis screening is indicated. Surgical Intervention Surgical treatment of AVN can be broadly categorized as either prophylactic measures to retard progression or necrosis de cadera procedures after femoral head collapse.

Small asymptomatic lesions do not warrant surgical intervention and are closely monitored with serial examination. If symptoms ensue, repeat imaging and surgical treatment are necrosis de cadera.

Osteonecrosis

Prophylactic measures The most commonly performed prophylactic surgical intervention is core decompression, whereby one or necrosis de cadera cores of necrotic femoral head bone is removed in order to stimulate repair. One study indicated that vascularized fibular grafts were more effective in preventing femoral head collapse than nonvascularized fibular autografts.

Namely, the clinical results of core decompression alone deteriorate with necrosis de cadera advanced lesions. The supplemental implementation of electrical stimulation with core decompression has provided disappointing results.

The placement of a structural graft through a core tract into the femoral head generally yields disappointing results. However, grafts placed into the femoral neck or directly necrosis de cadera the femoral head are more promising. Free vascularized fibular grafting significantly alters disease progression in precollapse lesions and is even useful in modifying disease in mildly collapsed and early arthritic hips.

Osteotomies can be necrosis de cadera or rotational, with the latter proving to be much more technically difficult.

Necrosis de cadera techniques may delay arthroplasty, but they are best suited for small precollapse or early postcollapse of the femoral head in patients who don't have an ongoing cause of AVN. However, osteotomies make subsequent arthroplasty more challenging and, unfortunately, these procedures are associated with an appreciable risk of nonunion.

The role of arthroscopy to better stage the extent of disease has emerged. Arthroscopic evaluation of the joint can help better define the extent of chondral flaps, joint degeneration and even joint necrosis de cadera and may help with the temporary relief of synovitis.
