研究表明，在实验动物中，囊内压力升高会导致股骨头缺血性坏死，但这与临床股骨颈骨折的相关性存在争议。我们研究了19例股骨颈囊内骨折患者，通过压力测量和超声检查显示囊内膨胀。Garden I级和II级骨折的关节内压力平均为66.4 mmHg，最高为145 mmHg。10例Garden III级和IV级骨折的平均压力为28 mmHg，最大为65 mmHg。大多数记录的囊内压力高到足以引起血管尴尬，建议应考虑早期对血肿进行减压。
It has been shown that raised intracapsular pressure causes avascular necrosis of the femoral head in experimental animals, but the relevance of this to clinical fractures of the femoral neck is controversial. We have studied 19 patients with intracapsular fractures of the femoral neck by pressure measurement and by ultrasonography to demonstrate capsular distension. The intra-articular pressure in Garden Grade I and II fractures averaged 66.4 mmHg with a maximum of 145 mmHg. In 10 Garden Grade III and IV fractures the average pressure was 28 mmHg with a maximum of 65 mmHg. Most of the recorded intracapsular pressures were high enough to have caused possible vascular embarrassment, and it is suggested that early decompression of the haemarthrosis should be considered.
