Ambulatory care learning/Assessment • Each student will have chance at least 2 times during the 4 weeks course to do full clinical assessment of real patient in the Orthopaedic outpatient clinic. • Student will be assessed for skills in obtaing and presenting a full history and clinical examination. • 5% of total mark Skills sessions • • • • Cast application and removal Principles of reduction and immobilization. Knee aspiration 5% of total mark Case-based learning • Six different cases covered the most common MSK problems which can be presented to the ER or orthopaedic/primary clinic • Cases will be assigned ahead of time to the students with clear objectives • 5% of total mark Attendance • 5% of total mark Orthopedic Surgery = Not only Bone Surgery • Orthopedic specialty is the branch of medicine which manage trauma and disease of Musculoskeletal system • It includes : bones, muscles, tendons, ligaments, joints, peripheral nerves, vertebral column and spinal cord and its nerves Orthopedic Specialty • Sub-Specialties in orthopedic include : – General – Pediatric Orthopedic – Sport and Reconstructive Orthopedic – Orthopedic Trauma – Arthroplasty – Spinal Surgery – Foot and Ankle surgery – Oncology – Hand Surgery Red Flags • Red Flags = Warning Symptom or Sign • Red flags should always be looked for and remembered • Presence of a red flag means the necessity for urgent or different action/intervention Examples of Red Flags Open Fractures : more serious and very high possibility of infection and complications Complicated Fractures : fracture with injury to major blood vessel, nerve or nearby structure Compartment Syndrome : increase in intracompartment pressure which endangers the blood circulation of the limb and may affect nerve supply Cauda Equina Syndrome : compression of the nerve roots of the Cauda Equina at the spinal canal which affect motor and nerve supply to lower limbs and bladder (also saddle or peri-anal area) Examples of Red Flags Infection of Bone, Joint and Soft Tissue Osteomyelitis : Infection of the bone Septic Arthritis :Infection of the joint Cellulitis :spreading Infection of the soft tissue May cause septicemia or irreversible damage . Multiple Trauma or Pelvic Injury: more than one fracture or injury sustained at the same time consider massive blood loss and associated injuries . Acute joint Dislocations : requires urgent reduction or may cause serious complications Alignment terminology Alignment Terminology: Cubitus Varus Alignment terminology: Cubitus Valgus Congenital or Acquired • Acquired conditions include : – Trauma – Developmental – Inflammation – Infection – Neuromuscular – Degenerative – Metabolic – Tumor Congenital Anomaly : Talipes Equino Varus TEV Traumatic Injuries • • • • • Fractures Dislocations Soft tissues injuries: ligaments, tendons Nerve injuries Epiphyseal injuries Fractures: Break in the continuity of bone Dislocations Complete separation of the articular surface Distal to proximal fragment Anterior, Posterior, Inferior, Superior Fracture Dislocation Dislocation with fracture of the bone Always X-Ray Joint Above and Below Avulsion Fracture Force due to Resisted Muscle Action:- “Avulsion” Transverse pattern Intra-articular Fractures • If displaced ; should always be treated by ORIF= Open Reduction and Internal Fixation failure to reduce and fix such fracture results in loss of function, deformity and early degenerative changes Soft tissue injuries of the knee Anterior Cruciate Ligament injury: MRI (Developmental Dislocation of Hip) DDH Developmental Foot deformity: Hallux Valgus Developmental: SCFE (Slipped Capital Femoral Epiphysis) Spinal Deformities: Kyphosis or Hyperlordosis Spinal Deformity: Scoliosis Degenerative Disorders • Occur at any joint • Can be primary or secondary • Can lead to pain and/or deformity and/or loss of function OA Hip Osteoarthritis of Knee Metabolic Disorders (Rickets): Bow Legs Osteoporosis: Pathological Fracture Osteoporosis: Colles fracture Bone Tumor Bone tumors Neurological Evaluation : Sensory & Motor Nerve Injury: Muscle wasting Spinal Cord Injury • Often results from fracture dislocation of spine • When injury is at cervical spine it may result in Tetraplegia or quad • Injury at dorsal spine may result in Paraplegia Neuromuscular disorder: Polio Chronic Osteomyelitis : discharging sinus Chronic Osteomyelitis : Sequestrum Physiotherapy for Orthopedic Patients • Physiotherapy is an important part of orthopedic and trauma management • It is used for : pain relief, prevention of stiffness, muscle strengthening, mobilisation of stiff joint or spine, training non-weight bearing or partial weight bearing • Physiotherapy modalities include: heat, cold, exercise, ultrasound, traction, electrical stimulation Clinical Skill: Cast application Clinical Skills: Knee Aspiration ORTHOEADIC HISTORY TAKING History taking skills • History taking is the most important step in making a diagnosis. • A clinician is 60% closer to making a diagnosis with a thorough history. The remaining 40% is a combination of examination findings and investigations. • History taking can either be of a traumatic or non-traumatic injury.
