Лучшие больницы для «Acetabular Fixation» в Ченнаи, Индия

The acetabulum forms the bony socket of the hip joint and is composed of three fused pelvic bones — the ilium, ischium, and pubis — meeting at the triradiate cartilage. Acetabular fractures are high-energy injuries most commonly resulting from motor vehicle collisions, falls from height, or dashboard-type impact mechanisms, though fragility fractures in elderly osteoporotic patients are an increasingly prevalent presentation. The acetabulum is classified using the Letournel–Judet system into five elementary types (posterior wall, posterior column, anterior wall, anterior column, transverse) and five associated types (T-shaped, posterior column with posterior wall, transverse with posterior wall, anterior column with posterior hemitransverse, and both-column fractures), each demanding a distinct surgical approach and fixation strategy. Displacement of even 2–3 mm can critically alter hip joint contact mechanics, accelerating cartilage degradation and leading to post-traumatic osteoarthritis within 5–10 years if left untreated.

• IDEAL SURGICAL CANDIDATES:
• Displaced acetabular fractures with ≥2 mm articular incongruity on CT axial, coronal, and sagittal reconstructions
• Posterior wall fractures involving >40% of the posterior wall (assessed by roof arc measurements and CT-based volumetric analysis)
• Hip fracture-dislocations that cannot be maintained concentrically reduced by closed means
• Posterior column fractures, transverse fractures, T-type fractures, and both-column fractures with secondary congruence failure

Standard OPEN Reduction AND Internal Fixation (ORIF):

The cornerstone of acetabular fracture surgery, ORIF involves surgical exposure of the fracture, manual or instrument-assisted reduction to restore articular congruity, and stabilization with plates and screws.

• Kocher–Langenbeck (KL) Approach: Posterior approach providing access to the posterior column, posterior wall, and the quadrilateral surface. Patient positioned prone or in lateral decubitus. Risks: sciatic nerve injury (1–5%), heterotopic ossification (HO — Brooker grade III–IV in 3–5%, reduced by indomethacin prophylaxis 25 mg TID for 6 weeks or single-fraction radiation therapy 700 cGy within 72 hours post-op), and superior gluteal artery injury.
• Ilioinguinal Approach (Letournel): Anterior approach accessing the anterior column, anterior wall, and inner cortex of the quadrilateral surface via three 'windows' (lateral, middle, medial). Avoids the hip joint entirely. Risks: lateral femoral cutaneous nerve neurapraxia, iliac vessel proximity, hernia.
• Pararectus / Modified Stoppa Approach: Increasingly preferred for anterior column–dominant, quadrilateral surface, and both-column fractures. Provides direct access to the inner pelvis and quadrilateral plate through a single infraumbilical midline incision. Lower morbidity than standard ilioinguinal; preferred in obese patients.
• Combined Approaches (KL + Ilioinguinal or KL + Stoppa): Used for complex associated fracture patterns (T-type, transverse+posterior wall, both-column with significant displacement). May require two separate surgical positions and extended operative time (4–8 hours).

Implant Systems & Fixation HARDWARE:

PRE-OPERATIVE PHASE (Days 1–5 before surgery, or immediately upon hospital admission for acute trauma):

• Emergency stabilization: ATLS protocol, hemodynamic resuscitation, and associated injury management (pneumothorax, abdominal organ injury, long bone fractures addressed first under damage control principles)
• Femoral skeletal traction: applied immediately in displaced fractures to relieve hip joint pressure and maintain limb length while awaiting definitive surgery (optimal window: within 72 hours for best reduction quality)
• Imaging workup: AP pelvis radiograph, Judet views, CT pelvis with 3D reconstruction, and additional studies as indicated (vascular imaging, MRI)
• Medical optimization: DVT prophylaxis initiated (LMWH — enoxaparin 40 mg SQ daily for standard risk; escalated dosing for high BMI), nutritional assessment, glycemic control, cardiac clearance
• Surgical planning: fracture classification, approach selection, implant templating, and — at advanced centers — virtual surgical planning using 3D-printed pelvic models or digital planning software (Synthes ProPlan, Brainlab)
• Anesthesia consultation, blood bank preparation (type and cross-match, cell salvage availability)
• Patient and family education: informed consent covering surgical risks (sciatic nerve injury, heterotopic ossification, DVT/PE, infection, malreduction requiring revision, post-traumatic arthritis progression, avascular necrosis of femoral head)
• Pre-operative antibiotics: cefazolin 2g IV (3g if BMI >35) 30–60 minutes before incision

INTRAOPERATIVE PHASE (Duration: 2.5–8 hours depending on fracture complexity):
