 Musculoskeletal and Orthopaedic Conditions: An In-Depth 

Musculoskeletal and orthopaedic conditions encompass a wide range of disorders affecting bones, joints, muscles, and connective tissues. These conditions can range from acute emergencies to chronic degenerative diseases and significantly impact mobility and quality of life. Understanding the key aspects of these conditions is essential for diagnosis, management, and treatment.

Orthopaedic Emergencies

Certain musculoskeletal conditions require immediate medical intervention. Septic arthritis, an infection within a joint, can rapidly destroy cartilage if left untreated. Spinal cord compression and cauda equina syndrome are critical conditions that can lead to permanent paralysis if not addressed promptly. Open fractures expose bones to infection, necessitating urgent surgical intervention. Infections such as tendon sheath infection in the hand can cause severe functional impairment if not managed swiftly.

Upper Limb Orthopaedic Issues

The upper limb is prone to various fractures and injuries. The shoulder and elbow often suffer from dislocations, rotator cuff tears, and impingement syndromes. Wrist fractures like Colles, Smith's, Barton's, Monteggia, and Galeazzi fractures are common and, depending on their severity, require immobilization or surgery.

Hand and Foot Conditions

Hand and foot disorders include ganglions, which are benign fluid-filled cysts affecting tendons or joints. These can cause discomfort and limit movement, often requiring aspiration or surgical removal if symptomatic.

Hip, Knee, and Ankle Issues

Hip conditions, including neck of femur fractures, are common in the elderly due to osteoporosis. Knee and ankle issues include ligament injuries, meniscal tears, and degenerative osteoarthritis, which can lead to chronic pain and mobility restrictions.

Spinal Disorders

The spine is vulnerable to conditions such as nerve root compression, autonomic dysreflexia, and herniated discs, all of which can cause severe pain and neurological deficits. Prompt diagnosis through imaging and timely intervention are crucial for preventing permanent damage.

Miscellaneous Bone and Joint Disorders

A variety of conditions affect the musculoskeletal system, including fat embolism syndrome, which occurs after fractures and leads to respiratory distress. Osteomalacia results from vitamin D deficiency and causes bone softening, while osteomyelitis is a serious bone infection. Osteochondritis dissecans leads to joint damage, and the Charcot joint is a neuropathic arthropathy causing severe joint deformity.

Joint Replacements and Bone Diseases

Surgical joint replacement is often performed for end-stage arthritis. Conditions such as Paget’s disease cause abnormal bone remodelling, leading to deformities. Pathological fractures occur due to weakened bones from underlying diseases like osteoporosis or cancer.

Musculoskeletal Malignancies and Trauma

Bone cancers such as osteosarcoma, chondrosarcoma, and Ewing’s sarcoma can be aggressive and require multidisciplinary treatment. Giant cell tumours are benign but locally destructive. Bone metastases from other cancers can weaken the skeleton, necessitating palliative care. Trauma surgery is vital in managing severe fractures and soft tissue injuries.

Paediatric Orthopaedics

Children present with unique orthopaedic conditions such as juvenile idiopathic arthritis, transient synovitis, and developmental dysplasia of the hip. Perthes disease affects the blood supply to the femoral head, while slipped capital femoral epiphysis (SCFE) leads to hip instability. Paediatric fractures differ from adult fractures due to the presence of growth plates. Rickets, caused by vitamin D deficiency, leads to bone deformities.

Rheumatology: Autoimmune and Degenerative Joint Disorders

Inflammatory and Degenerative Arthritis

Autoimmune joint diseases such as rheumatoid arthritis, osteoarthritis, and psoriatic arthritis cause joint pain, stiffness, and deformities. These conditions often require lifelong management with medications, physical therapy, and, in severe cases, surgery.

Muscular and Systemic Rheumatic Conditions

Ankylosing spondylitis affects the spine, leading to stiffness and fusion. Gout and pseudogout result from crystal deposition in joints, causing acute inflammation. Reactive arthritis follows infections, while fibromyalgia and polymyalgia rheumatica cause widespread pain and stiffness. Chronic fatigue syndrome is another musculoskeletal-related disorder impacting energy levels.

Ear, Nose, and Throat (ENT) Disorders

Ear Conditions

Common ear problems include otalgia (ear pain), otitis externa (swimmer’s ear), glue ear (middle ear effusion), and otitis media (middle ear infection). More chronic conditions include tinnitus, hearing loss, and vertigo. Disorders like childhood and adult deafness, otosclerosis, and vestibular schwannoma impact hearing and balance. Benign paroxysmal positional vertigo (BPPV), Ménière’s disease, and labyrinthitis are causes of severe dizziness.

Nasal and Sinus Disorders

Rhinosinusitis (acute and chronic), nasal fractures, epistaxis (nosebleeds), and nasal cancers are common nasal conditions. Cerebrospinal fluid leaks can mimic nasal discharge, requiring careful evaluation.

Throat Conditions

Throat-related conditions include tonsillitis, obstructive sleep apnea, and stridor due to airway obstruction. Croup, acute epiglottitis, and laryngomalacia are paediatric airway disorders. Dysphonia (voice disorders) and dysphagia (swallowing difficulties) often indicate neurological or structural problems. Head and neck squamous cell carcinoma, Bell’s palsy, and salivary gland disorders also fall under ENT pathology.

Psychiatry: Mental Health and Substance Abuse

Substance Abuse and Overdose

Addiction-related disorders include cocaine, LSD, nitrous oxide, and opioid misuse. Overdose management is critical, requiring immediate medical intervention.

Mood and Anxiety Disorders

Depression and bipolar disorder significantly impact daily life. Generalized anxiety disorder, panic disorder, and acute stress disorder can cause severe emotional distress.

Psychotic and Personality Disorders

Schizophrenia, psychosis, and the use of antipsychotics are central to psychiatric care. Personality disorders include paranoid, schizoid, antisocial, borderline, narcissistic, avoidant, and dependent types.

Eating Disorders and Sleep Disorders

Conditions like anorexia, insomnia, and electroconvulsive therapy (ECT) for severe depression play a crucial role in psychiatric care.

Paediatrics: Child Health and Development

Paediatric Life Support and Emergencies

Children require specialized emergency care, including newborn life support, intraosseous infusion, and anaphylaxis management.

Infectious Diseases

Paediatric infections include meningitis, encephalitis, measles, mumps, rubella, erythema infectiosum, hand-foot-mouth disease, roseola, and chickenpox.

Respiratory and Cardiovascular Disorders

Respiratory conditions like asthma, bronchiolitis, pneumonia, cystic fibrosis, and whooping cough are common. Congenital heart diseases include ventricular septal defect (VSD), atrial septal defect (ASD), and tetralogy of Fallot (ToF).

Gastrointestinal and Renal Disorders

GI conditions include coeliac disease, appendicitis, pyloric stenosis, and Hirschsprung disease. Renal disorders include urinary tract infections (UTIs), nephrotic syndrome, and Wilms' tumour.
