ABOS Orthopaedic Surgery Part II study plan

ABOS Orthopaedic Surgery Part II · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Trauma & Adult Reconstruction

  • Rank the top 25 trauma topics by ABOS test frequency and allocate study slots to each

  • Outline a decision algorithm for periprosthetic femur fractures around THA and TKA from classification through fixation vs revision

  • List weight-bearing and return-to-activity milestones for operatively treated tibial plateau, pilon, and acetabular fractures

  • Draft a one-page comparison of fixation constructs for displaced femoral neck fractures in patients over 65

  • Complete 40 trauma-focused multiple-choice questions and log every missed concept

Your checkpoint

A one-page trauma decision-algorithm sheet plus a logged error list from 40 practice questions

Week 2

Trauma & Adult Reconstruction

  • Recite the compartments, boundaries, and danger zones of the leg, forearm, and thigh for compartment syndrome

  • Sequence the workup and treatment of open fractures by Gustilo-Anderson grade

  • Compare surgical approaches to the distal femur and proximal tibia by structure at risk

  • Explain failure modes and revision strategies for periprosthetic joint infection workup

  • Score at least 70% on a 40-question mixed trauma and adult reconstruction set

Your checkpoint

A scored 40-question practice block with a written remediation plan for each miss

Week 3

Adult Reconstruction & Spine

  • Build a table of bearing surfaces, fixation methods, and indications for primary THA and TKA

  • Summarize the AAOS workup algorithm for the painful total joint and list serologic and synovial thresholds

  • Describe indications, contraindications, and complication profiles for lumbar fusion, decompression, and disc arthroplasty

  • Differentiate cauda equina, conus medullaris, and root-level syndromes by exam findings

  • Complete 40 adult reconstruction and spine questions and identify two weak subtopics

Your checkpoint

A completed bearing-surface and spinal-urgency reference table plus a 40-question score

Week 4

Spine & Sports Medicine

  • Map cervical and lumbar radiculopathy patterns to nerve root, dermatome, and motor deficit

  • Outline the trauma clearance algorithm for the spine and criteria for surgical versus nonoperative management of burst fractures

  • Compare ACL, meniscus, and cartilage procedures by indication, technique, and rehabilitation timeline

  • List return-to-sport criteria for the five most common sports procedures

  • Sit a 50-question timed mixed block covering adult reconstruction, spine, and sports

Your checkpoint

A mid-plan 50-question timed exam score with a ranked list of the three weakest domains

Week 5

Hand and Microvascular & Foot and Ankle

  • Diagram the flexor and extensor tendon zones of the hand and the repair and rehabilitation protocol for each

  • Explain the workup and treatment ladder for carpal tunnel, cubital tunnel, and de Quervain disease

  • Describe vascular and nerve repair principles, including timing, graft options, and reimplantation criteria

  • Outline the ankle fracture classification and syndesmotic injury management algorithm

  • Compare hallux valgus, flatfoot, and Achilles tendinopathy procedures by indication and complication

Your checkpoint

A hand tendon-zone and ankle-fracture algorithm card set reviewed aloud without notes

Week 6

Shoulder and Elbow & Pediatrics

  • Outline the evaluation and treatment of rotator cuff tears, shoulder instability, and proximal humerus fractures

  • Summarize elbow instability and distal humerus fracture management and the approach to the stiff elbow

  • Describe the pediatric fracture management principles and physeal injury classification

  • Compare developmental dysplasia of the hip, Legg-Calve-Perthes, and slipped capital femoral epiphysis by presentation and treatment

  • List scoliosis and foot deformity management criteria in children

Your checkpoint

A two-column shoulder/elbow versus pediatric comparison sheet plus 30 answered questions

Week 7

Musculoskeletal Oncology & Basic Science

  • State the workup, staging, and biopsy principles for suspected bone and soft tissue sarcoma

  • Differentiate benign bone lesions by age, location, and radiographic pattern

  • Recite the biomechanics, bone healing biology, and biomaterials principles most tested in basic science

  • Explain the classification and treatment of metastatic bone disease and impending pathologic fracture

  • Complete 40 oncology and basic science questions and log every miss

Your checkpoint

A lesion-differential matrix by age and location plus a 40-question scored set

Week 8

Practice-Based/Professionalism & Trauma & Adult Reconstruction & Hand and Microvascular

  • Review informed consent, documentation, and professionalism scenarios and the ethical framework for each

  • Re-test the three weakest domains identified at week 4 and confirm improvement

  • Complete two full-length timed 100-question mixed exams and record domain-level accuracy

  • Consolidate all error logs into a single high-yield review sheet

  • Rehearse a rapid-fire review of the top 50 high-frequency facts across all domains

Your checkpoint

Two full-length timed exam scores with domain breakdowns and one consolidated high-yield review sheet

Milestones

Week 2: Complete at least 80 trauma and adult reconstruction questions with a documented error log

Week 4: Score at least 65% on the 50-question timed mixed block and identify three weakest domains

Week 6: Finish reference cards for hand, foot and ankle, shoulder and elbow, and pediatrics and answer 30 questions per domain

Week 8: Score at least 70% on both full-length timed exams with no domain below 60%
