♦ Acetabular fracture patients often have associated injuries♦ Restoration of hip joint congruity and stability are the treatment goals♦ Stable concentrically reduced fractures can be considered for non-operative management♦ Operative treatment is indicated for fractures with hip joint instability or incongruity♦ Choosing the proper surgical approach is one of the most important treatment aspects♦ Although the surgery is demanding, an experienced surgeon can obtain excellent results.

AbstractHip joint instability has been targeted as an important issue that affects normal hip function. The diagnosis of hip instability could be very challenging and currently, there is no definitive diagnostic test. Hip instability results in an excessive amount of translation of femoroacetabular articulation, leading to changes on the dynamic loading of the hip. These changes in femoroacetabular translation could be evaluated by human movement analysis methods. The purpose of this study was to describe the triaxial and overall magnitude of acceleration in patients diagnosed with hip instability during gait cycle and compare those results with a control group. Our hypothesis was that acceleration values obtained from the instability group would be higher than asymptomatic controls. Ten patients with previously diagnosed hip instability were included and 10 healthy and asymptomatic subjects were enrolled as control group. Triaxial accelerometers attached bilaterally to the skin over the greater trochanter were used to record acceleration during walking on a treadmill. The overall magnitude of acceleration and the axial, anteroposterior and mediolateral accelerations (x/y/z) were obtained during gait. Mean overall magnitude of acceleration was higher in the hip instability group compared with the control group, 1.51 g (SD: 0.23) versus 1.07 g (SD: 0.16) (P = 0.022). The axial, anteroposterior and mediolateral accelerations significantly differed between the two groups. The axial and mediolateral accelerations showed to be higher for the hip instability group while the anteroposterior axis acceleration was lower.

The Stability

Hip instability in children with cerebral palsy (CP) is a serious unresolved problem in modern orthopedics. Objective. To analyze the state of the problem of the hip joint instability in children with cerebral palsy and determine the prospects for its solution. Me­thods. A thematic review of 68 studies was made. Results. The basis for the prevention of instability of the hip joint should be a systema­tic X-ray screening at least once a year.  The instability of the hip joint is based on neurological disorders, if the index of migration of the femoral head (MP) is less than 30 %, the application of selective dorsal rhizotomy or baclofen pump is promising and justified. If MP > 30–100 % dorsal rhizotomy can be used after surgical correction of abnormalities in the hip joint to reduce the recurrence rate. The existing surgeries on the pelvic and femur is sufficient to restore the stability of this joint, even in the most severe cases, but the result is not always possible to maintain due to the recurrence of the deformity. The requirement for hip intervention in a patient with cerebral palsy is a preventive focus, by which we mean not only the achievement of joint stability, but also the creation of conditions for its preservation. Temporary blockage of the medial portion of the femoral head growth area is a minimally invasive procedure and may be recommended for use alone or as an adjunct to hip soft tissue release or for hip and bone surgery. However, it is still unclear at what age it is better to block the growth plate of the femoral head, whether and how often to change the clamps and so on. A prerequisite for the treatment of patients with this pathology is an individual approach, taking into account the degree of displacement of the femoral head, the presence of pathology of adjacent joints, the age of the child and the severity of the disease.  Correction of existing deviations should be performed in one step at many levels.
