“…In a normal hip joint, however, there is no increase in the intracapsular pressure within the normal range of rotation around the axis of the neck of the femur, only in the extreme rotatory positions (Wingstrand 1997). Several studies have demonstrated an increased intracapsular pressure in such hip disorders as arthrosis (Robertsson et al 1995), septic arthritis, juvenile chronic arthritis (Hasegawa and Ito 1991), synovitis (Wingstrand et al 1987), congenital dislocation of the hip (Wingstrand 1997), loosening of hip prosthesis (Robertsson et al 1997), and trauma (Bonnaire et al 1998). It is generally accepted that an increase in the intracapsular volume of fluid, due either to the bleeding following a trauma or to a septic/aseptic synovitis, contributes to an increased intracapsular pressure (Wingstrand et al 1987, Bonnaire et al 1998).…”

Intracapsular pressure and interleukin-1β cytokine in hips with acetabular dysplasia

Background and purpose Several studies have demonstrated an increased intracapsular pressure in several hip disorders such as septic arthritis, synovitis, and trauma. We therefore measured the intracapsular pressure in different positions in early dysplasic hips and its relation to the concentration of interleukin-1β (IL-1β), the volume of joint fluid, and the clinical and radiographic findings before a periacetabular osteotomy.Methods 12 female patients (12 hips, mean age 35 (18–52)) with hip dysplasia were investigated. The intracapsular pressure was recorded and we investigated possible correlations with the Harris hip score, the Tönnis scale, radiographic findings, the volume of joint fluid, and the concentration of IL-1β.Results An increased intracapsular pressure was noted, especially in flexion or extension with internal rotation. We found positive correlations between the intracapsular pressure and both the volume of joint fluid and the concentration of IL-1β.Interpretation Increased intracapsular pressure varied with different positions, indicating the presence of synovitis resulting from early osteoarthritis in dysplastic hips. Positive correlations between the pressure and both the concentration of IL-1β and the volume of joint fluid suggest that the inflammatory cytokines produced by the synovial membrane as a consequence of mechanical instability of the hip joint may be of importance for the initiation and/or development of osteoarthritis in dysplastic hips.

“…The relationship between intracapsular hip pressure and volume has been evaluated before [3,4,8,9,13] with the most recent attention focused by Yen et al [14] on the relationship of hip volume, position, and pressure. Our methodology used a modification of the approach Although the previous study has outlined an intracapsular pressure-volume relationship, these studies cannot possibly be extrapolated to immature nonarthritic atraumatic hips.…”

“…Increased intracapsular hip pressures have been documented in both traumatic [1][2][3] and nontraumatic [4][5][6][7][8] hip conditions. Several previous studies have reported that the rise in intracapsular pressure is secondary to hemarthrosis and acutely results in pain and in a limited range of motion [4,7]. It has been postulated that a significant increase in intracapsular hip pressure may sometimes result in bony venous congestion [9].…”

This study outlines a relationship between joint volume, positioning, and intracapsular pressure in a healthy hip. After measuring the native intracapsular pressure in 12 porcine specimens, each joint was injected with radio-opaque-colored saline as pressures were measured. At 20 mmHg, the hip was placed in its position of ease and then in differing positions while pressures were recorded. Position significantly altered pressures, with the lowest values in neutral and the highest in hyperextension (P<0.001). Extreme hip positions may be detrimental because of high pressures created within the joint, possibly explaining complications associated with some hip diagnostic and treatment methods.
