There remains confusion in the literature with regard to the spinopelvic relationship, and its contribution to ideal acetabular component position. Critical assessment of the literature has been limited by use of conflicting terminology and definitions of new concepts that further confuse the topic. In 2017, the concept of a Hip-Spine Workgroup was created with the first meeting held at the American Academy of Orthopedic Surgeons Annual Meeting in 2018. The goal of this workgroup was to first help standardize terminology across the literature so that as a topic, multiple groups could produce literature that is immediately understandable and applicable. This consensus review from the Hip-Spine Workgroup aims to simplify the spinopelvic relationship, offer hip surgeons a concise summary of available literature, and select common terminology approved by both hip surgeons and spine surgeons for future research.

Aims. This study analysed the clinical and radiological outcome of
anatomical reduction of a moderate or severe stable slipped capital
femoral epiphysis (SCFE) treated by subcapital osteotomy (a modified
Dunn osteotomy) through the surgical approach described by Ganz. . Patients and Methods. We prospectively studied 31 patients (32 hips; 16 females and
five males; mean age 14.3 years) with SCFE. On the Southwick classification,
ten were of moderate severity (head-shaft angle >
30° to 60°) and
22 were severe (head-shaft angle >
60°). Each underwent open reduction
and internal fixation using an intracapsular osteotomy through the
physeal growth plate after safe surgical hip dislocation. Unlike
the conventional procedure, 25 hips did not need an osteotomy of
the apophysis of the great trochanter and were managed using an
extended retinacular posterior flap. . Results. Clinical outcome was assessed using the range of movement and
the Harris Hip (HHS), Western Ontario and McMaster Universities
Osteoarthritis (WOMAC), and Merle d’Aubigné scores, while radiological
measurements included slip and alpha angles. The mean duration of
follow-up was 24.1 months (12 to 40). . There was a significant improvement in all clinical and radiological
measurements after treatment (p <
0.001). Post-operative major
complications were one deep infection and one case of femoral head
collapse. . Conclusion. These findings suggest that a modified Dunn osteotomy carried
out through Ganz

Exposure of the hip by osteotomy of the anterior part of the greater trochanter is described. This maintains the continuity of the tendinous junction between the anterior half of gluteus medius and the vastus lateralis and preserves intact the insertion of gluteus minimus into the anterior surface of the trochanter. The nerve supply to these muscles is not compromised and good abductor function is retained. The

The aim of this cadaver study was to identify
the change in position of the sciatic nerve during arthroplasty
using the posterior surgical approach to the hip. We investigated
the position of the nerve during this procedure by dissecting 11
formalin-treated cadavers (22 hips: 12 male, ten female). The distance
between the sciatic nerve and the femoral neck was measured before
and after dislocation of the hip, and in positions used during the
preparation of the femur. The nerve moves closer to the femoral
neck when the hip is flexed to >
30° and internally rotated to 90° (90°
IR). The mean distance between the nerve and femoral neck was 43.1
mm (standard deviation ( This study demonstrates that the sciatic nerve becomes closer
to the operative field during hip arthroplasty using the posterior
approach with progressive flexion of the hip. Cite this article:
