Total Hip Arthroplasty: Pelvic Discontinuity - Plastic Surgery Key
2016年7月31日 · Compression plating of the posterior column with 3.5-mm reconstruction plates, supplemented by porous metal shell in the acute fracture setting, has seen relatively positive results, with survivorship at 18 to 36 months of up to 100%. 15, 18, 20 This suggests that, in acute discontinuity, the bone does indeed possess fracture healing potential.
Outcomes in Acetabular Revision for Acute Pelvic Discontinuity ...
2024年11月29日 · All patients were managed with open reduction and internal fixation (ORIF) of the discontinuity with a posterior column plate and highly porous cup. The primary outcome was acetabular component survivorship using Kaplan-Meier analysis.
2024年11月30日 · After exposing the posterior column, the acetabular component was 86 removed. A 5.0 mm Schanz pin was placed in the ischium with a t-handle to de-rotate the 87 posterior hemipelvis and achieve our reduction. For fixation, one or two 3.5 mm reconstruction 88 plates were used with a minimum of four cortices on each side of the discontinuity.
Outcomes in Acetabular Revision for Acute Pelvic Discontinuity ...
2024年11月30日 · As a result, plating of the posterior acetabular column can be utilized to stabilize the discontinuity, provide intact columns for a pinch fit for a revision shell, and promote fracture healing via compression [1].
Acetabular Component Revision: Pelvic Discontinuity
Reconstruction of major column defects and pelvic discontinuity in revision total hip arthroplasty. Bridging massive acetabular defects with the triflange cup: 2- to 9-year results. Identification and management of pelvic discontinuity.
RECONSTRUCTION OF MAJOR COLUMN DEFECTS AND PELVIC DISCONTINUITY …
A posteriorly placed AO 4.5-mm pelvic reconstruction plate with 10 to 12 holes was used in nine cases of pelvic discontinuity and in five cases of posterior column bone loss. This plate extended from the most inferior extent of the ischium across the …
Reconstruction of major column defects and pelvic discontinuity …
2000年10月1日 · This article reviews a long-term experience using a combination of pelvic reconstruction plates and bulk allografts to deal with unusually severe problems, such as pelvic discontinuity and major column loss in which the entire acetabular wall became nonsupportive after failed arthroplasty and reconstruction problems.
Acetabular Distraction: An Alternative for Severe Defects with …
Stabilization of a pelvic discontinuity with a posterior column plate with or without an associated acetabular cage sometimes results in persistent micromotion across the discontinuity with late fatigue failure and component loosening.
PELVIC DISCONTINUITY: MANAGEMENT OPTIONS | Bone
A hemispheric acetabular component with posterior column plating is a good option for acute pelvic discontinuities. However, healing potential is dependent on host's biology and characteristic of the discontinuity. The plate should include 3 screws above and 3 screws below the discontinuity with compression in between.
The Treatment of Pelvic Discontinuity During Acetabular Revision
2005年6月1日 · If healing potential of the discontinuity exists, the discontinuity should be treated in compression with a posterior column plate and structural allograft or with the use of trabecular metal acting as an internal plate.
