In summary, these patients had the following characteristics: (1) the femoral head was located in the posterior-superior direction relative to its original position (2) a pseudoacetabulum was formed around the dislocated femoral head (3) pathoanatomical changes were present in the original acetabulum (4) secondary osteoarthritis and (4) limb shortening. In four of them (all neglected more than 1 year), the formation of a “pseudoacetabulum” could be identified. Pai reported 26 patients with unreduced posterior hip dislocations. In some patients, more pathological findings could be identified. Another important point to note is that with increasing unreduced dislocation time, secondary osteoarthritis could be identified. Considering the number of years that had elapsed since the accident and the changes that must have taken place in the acetabular cavity, no attempt of reduction was made in that study. The first one from Michelmore in 1889 involved a 10-year-old female who was diagnosed with old unreduced dislocation of hip joint. There are some reports related to patients with short-term or long-term unreduced hip joint dislocation.

Therefore, the answers regarding how to diagnose and how to treat these patients with long-term unreduced hip dislocation still have clinical usefulness. In other cases, the patient might be correctly diagnosed but cannot be treated for socioeconomic reasons. that patients with hip dislocation might be neglected in developing countries. It had already been reported by Pai et al. However, the consequences if the femoral head is not reduced after injury remain unclear. If this fails, surgical interventions such as open reduction or periacetabular/proximal femoral osteotomy (if the hip joint remains unstable after initial treatment) may be performed to help relieve pain and promote a functional outcome. Generally, when traumatic fracture-dislocation of the hip joint is identified on the patient, an emergency reduction should be performed to restore the normal anatomical relationship between the femoral head and acetabulum. Traumatic fracture-dislocation of the hip joint is considered a severe injury that is commonly caused by high-violence etiologies, such as traffic accidents or falls from a height.

The prognosis of most patients after total hip arthroplasty is expected to be excellent or good. The new classification system could help surgeons estimate potential difficulties during total hip arthroplasty. The average Harris hip score postoperatively was 89.94 ± 5.78 points (range: 79–98 points). For patients with type C injury, the situation was similar to that of revision surgery.

For patients with type B injury, due to atrophy or partial bone deficiency of the original acetabulum, the surgical procedure for total hip arthroplasty was probably similar to those for patients with developmental dysplasia of the hip. For patients with type A injury, the surgical procedures for total hip arthroplasty were similar to “standard” total hip arthroplasty. With the combined application of X-ray, CT scans and 3D reconstruction, 93.8% of these patients (sensitivity = 93.8%, Youden’s index = 0.93, intraclass correlation coefficient = 0.95) could be diagnosed correctly. The surgical procedures and prognosis of the patients were also investigated. We evaluated the bone conditions of the original acetabulum and classified the patients into three types (four subtypes). The diagnostic values of three different types of common radiological examinations were evaluated. We retrospectively reviewed 16 patients from 2010 to 2017. However, as this is an uncommon injury, few studies have systematically investigated these patients. Neglected long-term unreduced hip joint dislocation with secondary osteoarthritis and pseudoarthrosis poses a great challenge to hip surgeons.
