Extensor tendons anatomy

Extensor tendons anatomy

Extensor tendons are divided into six different compartments discussed below. The Extensor retinaculum will prevent tendon bowstringing at the wrist Sagittal bands will aid in metacarpophalangeal(MCP) joint extension, and attach to the volar plate Central slip will insert on the base of the middle phalanx and aid in proximal interphalangeal joint extension Interossei and lumbricals […]

 Development of the Proximal Femur

Development of the Proximal Femur

Development of the proximal femur begins after 6 weeks of fertilization however the primitive limb bud form after 3 weeks of fertilization. To summarize: 3 weeks after fertilization Primitive limb bud form Filled with mesenchymal At 6 weeks, mesenchyme condensed to outline ilium, ischium, pubis, and femoral shaft (Interzone develops between femoral head and acetabulum) […]

Ottawa Ankle Rules

Ottawa ankle rules are used to sort the ankle injuries to do or not do the X-rays in the patient in OPD. To decide the need for an X-ray in ankle injury Pain around the malleolus Inability to take weight immediately after injury Inability to take four-step in Emergency/ OPD Bony tenderness at posterior edge […]

Proximal femoral focal deficiency

Development defect of the proximal femur recognizable at birth in which the femur is shorter than normal and there is the apparent discontinuity between the femoral neck and shaft PFFD: Unstable hip joint, Shortening Etiology Theories: Sclerotome subtraction theory (Injury to neural creast cells) Boden theory (defect in proliferation and maturation of chondrocytes in proximal […]

Intoeing Gait

In-toeing gait is usually attributed to metatarsal adductus (in infants), internal tibial torsion (in toddlers), and femoral ante version (in children <10 years) The child walks with foot will turn inwards instead of pointing straight ahead Etiology: Excessive femoral anteversion Internal tibial torsion Metatarsal adductus Excessive femoral anteversion: The angle between the neck of the […]

 Femoral Neck Stress Fracture

Femoral Neck Stress Fracture

Femoral Neck Stress Fracture is classified according to Fullerton (1988) as Fullerton and Snowdy (1988) Type Fracture Type Incomplete (< 50% femoral neck width) (Management) Complete (> 50% femoral neck width) (Management) Type I Tension Surgical fixation: DHS Surgical fixation: DHS Type II Compression Conservative (Unless significant pain or unable SLR) Surgical fixation (Cannulated Hip […]

 NanoTechnology in orthopaedics

NanoTechnology in orthopaedics

Nanotechnology is defined as the “Production and manipulation of material on a scale of < 100 nm and integration of this nanomaterial in a microscopic and macroscopic system“. Nanoparticles differ from large particles in applying the classical law of physics Composed of grain size much much smaller than conventional particle but have some basic atomic […]

Nerve supply of the Bladder

Nerve supply of the bladder is explained in the figure below with differences between the autonomic and autonomous bladder. Autonomic Bladder Autonomous Bladder Damage above sacral plexus (Suprasacral) Damage to sacral plexus UMN Type (Spastic) LMN Type (Atonic) Reflex emptying of the bladder Reflex activity lost Small capacity -> Hypertonic bladder empty suddenly Overflow incontinence […]

 Functional cast bracing

Functional cast bracing

A functional cast is a type of bracing where the limb is allowed to do functions with a brace kept in . It helps in continuing function while a fracture is uniting encourages osteogenesis promotes the healing of tissue and prevents the development of joint stiffness (accelerate rehabilitation) This is not a method of fracture […]
