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 intra compartment 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 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

OA Hip

Osteoarthritis of Knee

Metabolic Disorders (Rickets): Bow Legs

Osteoporosis: Pathological Fracture

Osteoporosis: Colles fracture

Bone Tumor

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

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.

Objective • At the end of this session, students should be able and know how to take a MSK relevant history.

Competency expected from the students • Take a relevant history, with the knowledge of the characteristics of the major musculoskeletal conditions

STRUCTURE OF HISTORY • Demographic features • Chief complaint • History of presenting illness – MOI – Functional level • • MSK systemic review Systemic enquiry PMH PSH • • • Drug Hx Occupational Hx Allergy Family Hx Social Hx

MSK systemic review • • • Pain Stiffness Swelling Instability Deformity Limp Altered Sensation Loss of function Weakness

Pain • Location – Point to where it is • Radiation – Does the pain go anywhere else • Type – Burning, sharp, dull • How long have you had the pain • How did it start – Injury • Mechanism of injury • How was it treated? – Insidious

Pain • Progression – Is it getting worse or is it remaining stable – Is it better, worse or the same • When – Mechanical / Walking – Rest – Night – Constant • Aggravating & Relieving Factors – Stairs – Start up, mechanical – Pain with twisting & turning – Up & down hills – Kneeling – Squatting

Pain • • • Where: location/radiation When: onset/duration WWQQAA Quality: what it feels like Quantity: intensity, degree of disability Aggravating and Alleviating factors Associated symptoms
