THR: Acetabular Reaming

      – Patient Position:     – ensure that patient has not rotated anteriorly, for this may allow acetabular component to be placed in retroverted position;     – ensure that patient’s torso is not tilted inferiorly (as can occur from a bean bag), as this can cause reaming in an              excessive … Read more

Technique for Acetabular Cup Removal

        – Discussion:     – considerations:            – removal of press fit components can often be complicated by heavy bone ingrowth, insertion of under-reamed                   components, or insertion of oversized peripherally oversized cups;     – acetabular exposure:   … Read more

T Acetabular Frx

                – See: Transverse Fractures of the Acetabulum – Discussion:     – compared to other types of acetabular frx, the T Shaped – Posterior Wall Frx may              have the highest prevalence of poor clinical results;     – T shaped fractures which are known to be especially … Read more


– Discussion:     – involves Salter osteotomy + osteotomy of both rami which results in placing articular cartilage over femoral head;     – indicaitons:          – older children w/ residual dysplasia & subluxation in whom there is minimal potential for remodeling;          – older children w/ DDH since … Read more

Semitubular Plates

– Discussion:     – semitubular Plates are designed in the shape of half tube;     – they are only 1 mm thick and have low rigidity;     – plate is used only in areas where they are subject to tensile forces;     – oval plate holes allow some axial compression if … Read more

Screw Fixation of Acetabular Components

– See: Acetabular Component Menu Discussion it is controversial as to whether screws are necessary in THR, and there are relative advantages and disadvantages; cups should be designed with only 2-3 holes so as to maximize the porous coating surface and to minimize conduit for osteolysis; acetabular cup insertion: advantages of screw insertion: theoretically, screw … Read more

Sacroiliac Fracture – Dislocations

– See:        – Posterior Pelvic Injuries         – Sacral Fractures        – cresent fracture: (iliac fracture)  – Fixation Techniques:     – SI joint dislocation: posterior screw fixation:           – Kellum et al 1987, unstable SI joint dislocations can produce long term pain in 60% that are treated non operatively  … Read more

Rx of CDH: Ages 3 years to 8 years

– See: Chiari osteotomy – Discussion:     – most of these pts will require open reduction;     – usually involves open reduction combined with femoral shortening;     – femoral shortening:           – aids in reduction;           – decreases potential complications;         … Read more
