Study Notes
Instrumentation
- Essential surgical instruments include telescopes, light sources, cameras, suction devices, cautery, and normal saline bags (3000ml).
Surgery of the Knee
- Arthroscopy of the knee is the most common arthroscopic procedure, used for diagnostic purposes, biopsies, and repairs like meniscus and ACL reconstruction.
- Anesthesia options for knee surgery include general anesthesia (GA), spinal, and local anesthesia.
- Tourniquets are typically applied to the thigh but rarely inflated during procedures.
- Common knee injuries include torn medial collateral ligaments, medial menisci, and anterior cruciate ligaments.
Arthroscopic Resection and Repair of Meniscal Tear
- Menisci play a crucial role in load distribution and stability within the knee joint.
- Meniscus tears are the most frequent injuries requiring surgical intervention.
- The procedure involves cutting the anterior horn of the meniscus, debriding chronic tears, and potentially suturing in vascular zones using absorbable sutures.
Arthroscopic Anterior Cruciate Ligament (ACL) Repair
- The ACL is vital for knee stability and is the most commonly torn ligament.
- Injuries usually occur under simultaneous anterior and rotational stresses, often affecting athletes.
- A patellar tendon graft is the most common repair method, requiring a series of precise steps including guide pin insertion, suture placement, and graft fixation with heavy sutures.
Total Knee Arthroplasty (TKA)
- TKA replaces worn knee surfaces, with arthritis as the leading diagnosis.
- The procedure aims to enhance mobility and stability, preserving normal ligaments and maintaining soft tissue balance.
- Types of knee implants: unicompartmental, bicompartmental, and tricompartmental (most commonly used).
- Implants can be unconstrained, semiconstrained, or fully constrained, determined by bone stability.
- Fixation methods include cemented or non-cemented techniques, tailored to patient needs.
Surgery of the Hip
Hip Fractures
- Classified into three types based on location: femoral neck, intertrochanteric, and subtrochanteric fractures.
- Intertrochanteric fractures are prevalent in elderly women and treated with screws and plates.
- Surgical procedures require specific instrumentation, including a fracture table, Dynamic Hip Screw (DHS), and fluoroscopy for guidance.
Femoral Neck Fractures
- Require reduction prior to fixation to prevent nonunion or avascular necrosis.
- Instrumentation involves a fracture table with traction for proper alignment during surgery.
Lumbar Spine Surgery
Lumbar Laminectomy
- Involves removing lumbar disks to relieve spinal pressure, mainly for spinal stenosis or ruptured disks.
- Patients are positioned in the prone position for optimal access.
- Instrumentation includes various rongeurs, elevators, retractors, and bipolar cautery.
Spinal Fusion
- Addresses scoliosis by fusing vertebrae to correct lateral deviations.
- Harrington Rods are the primary fixation instruments, with distraction rods on the concave side and compression rods on the convex side.
- Blood replacement measures are vital due to potential extensive dissection.
Hand Surgery
Carpal Tunnel Release
- Performed to relieve median nerve entrapment by cutting the carpal ligament.
- The procedure is often quick, with local anesthesia or Bier Block employed, primarily performed by plastic surgeons.
