This document discusses thoracolumbar fractures, including their biomechanics, patterns of injury, stability classifications, and clinical assessment. Key points include:
- The thoracolumbar spine has three biomechanical regions, with the transition zone of T9-L2 being most prone to injuries from flexion, extension, or rotation.
- Fracture patterns include flexion, extension, burst, compression, Chance, and translational injuries.
- Stability depends on the integrity of the anterior and posterior columns. Burst fractures disrupting both columns are always unstable.
- Flexion distraction and translational injuries involving three columns are highly unstable and may require operative repair.
Acetabular fractures are typically caused by high-energy trauma and require careful evaluation using CT scans and plain radiographs to classify the fracture pattern according to the Letournel classification system, which describes fractures of the anterior and posterior columns. Operative treatment is indicated for displaced fractures while non-operative treatment with skeletal traction can be used for non-displaced or minimally displaced fractures.
The document discusses the anatomy and classification of acetabular fractures. It notes that Judet and Letournel analyzed the anatomy of the innominate bone and established planes and angles. Acetabular fractures are classified using the Judet and Letournel or Orthopaedic Trauma Association systems. Treatment may involve non-operative management with traction or surgery depending on the fracture pattern and stability. Surgical approaches are dependent on the specific fracture location and goal is anatomic reduction to restore a congruent joint. Complications can include arthritis, heterotopic ossification, nerve injuries and infection.
Thoracolumbar fractures account for 50% of spinal fractures and often occur between the T9 and L2 vertebrae. They are commonly caused by high-energy trauma like motor vehicle accidents or falls. Assessment involves neurological examination, imaging like x-rays and CT scans to evaluate bone injury and MRI to assess soft tissues. Treatment depends on factors like degree of vertebral compression and kyphosis, with non-operative options for mild cases and surgical stabilization and fusion for more severe injuries or neurological compromise. Rehabilitation focuses on restoring function, preventing complications, and bracing to solidify healing.
High tibial osteotomy (HTO) is a surgical procedure that involves correcting angular deformities of the tibia. It has been used to treat conditions like osteoarthritis, osteochondritis dissecans, and malalignment. There are several techniques for HTO including lateral closing wedge osteotomy, medial opening wedge osteotomy, and dome osteotomy. HTO can help relieve pain from unicompartmental osteoarthritis and delay the need for knee replacement in young, active patients. Potential complications include fracture, nonunion, nerve palsy, and issues that can make later knee replacement more difficult. Precise surgical planning and fixation are important for achieving good outcomes from HTO.
This document provides an overview of thoracolumbar fractures, including epidemiology, clinical evaluation, classification systems, radiographic evaluation, treatment approaches, and specific surgical techniques. It discusses the anatomy of the thoracolumbar region, mechanisms of injury, neurological assessment tools, radiographic indicators of instability, and non-operative and operative treatment options depending on the fracture classification.
This document provides an overview of the anatomy of the ankle joint and ankle arthrodesis (fusion). It describes the bones and ligaments that make up the ankle joint, including the tibia, fibula, and talus. It discusses the indications, contraindications, surgical technique, and postoperative care of ankle arthrodesis, which is performed to treat ankle arthritis and pain. The optimal position for fusion is slight dorsiflexion with mild hindfoot valgus and external rotation. Preoperative planning involves assessing bone quality, alignment, and arthritis in other joints like the subtalar.
The document discusses posterior malleolus fractures of the ankle. It summarizes that CT scan is important for evaluating these fractures and determining treatment. While fragment size was traditionally used to dictate treatment, the focus should be on restoring joint congruity. A posteromedial surgical approach allows fixation of fractures that extend into the medial malleolus, like Haraguchi type II fractures. This approach provides good outcomes while avoiding complications when used to address complex posterior malleolus fractures.

Patella dislocation is a common problem in the young. Recurrence of dislocation can be significant problem causing pain and discomfort. The assessment and guidelines towards non-surgical and surgical treatment options are discussed here.
Poller or blocking screws are used to stabilize fractures treated with small diameter intramedullary nails. They guide the nail like "poller" traffic devices guide vehicles. Blocking screws increase stability of distal and proximal metaphyseal fractures after nailing and can help manage malunited fractures. They work by narrowing the canal to guide the nail anteriorly and prevent sagittal plane deformity. Blocking screws are typically placed medially and laterally as close to the fracture as possible for optimal stabilization. Their placement on the concave side of deformities helps improve reduction by deflecting the nail.
This document discusses the classification, treatment principles, and surgical techniques for tibial plateau fractures. There are two main subgroups - high-energy fractures in young patients and low-energy fractures in elderly osteoporotic patients. Treatment goals are to decompress soft tissues, reconstruct the joint surface and mechanical axis, and allow early motion. Surgical approaches include anterior, medial, and lateral. Fixation methods depend on the fracture but may include plates, screws, hybrid fixators, or less invasive systems like LISS. Good outcomes can be achieved with anatomical reduction, rigid joint fixation, and functional stabilization of the metaphysis while restoring soft tissue stability.
Humeral shaft fractures can often be treated nonoperatively with a brace, though operative options include plating, flexible nailing, or locked intramedullary nailing. Plates and nails have similar union rates but nails have more complications so plates are generally preferable. Flexible nails are also an effective option. Radial nerve palsy is a risk, especially with distal fractures, and may require exploration. Most humeral shaft fractures heal well with either operative or nonoperative treatment depending on the specific situation and patient factors.
This document discusses the management of thoracolumbar spine injuries. It begins by outlining common causes of injury and why the thoracolumbar junction is susceptible. It then covers fracture classification systems including Denis' three column concept and the AO/Magerl classification. Evaluation and management approaches are discussed including non-operative treatment with bracing and operative options depending on fracture pattern and neurological status. Surgical techniques like posterior instrumentation with or without decompression or combined anterior-posterior procedures are mentioned.
This document summarizes paediatric forearm fractures. [1] Forearm fractures are common in children, often resulting from falls or sports injuries. [2] Clinical examination focuses on pain, swelling, deformity and neurological status. [3] Treatment depends on fracture type and aims to restore function while allowing healing with minimal deformity. Conservative treatment is usually sufficient but surgery may be needed for more complex fractures.
The document discusses the anatomy, types, mechanisms of injury, evaluation, and management of proximal tibial fractures. Key points include:
- Proximal tibial fractures can be articular or nonarticular, with the lateral plateau most commonly involved. Injuries occur from shear, compressive, or axial forces on the knee.
- Evaluation includes physical exam of neurovascular status and knee stability as well as imaging like x-rays and CT to classify the fracture.
- Treatment depends on the fracture classification system used (Schatzker or AO/OTA) and involves non-operative management with immobilization for non-displaced fractures or operative management with open reduction and internal fixation for displaced or
The "terrible triad" refers to an elbow dislocation with fractures of the coronoid process and radial head. This is an extremely unstable injury that often leads to recurrent instability, stiffness, and arthritis. Surgical treatment aims to address all fractures, repair ligaments, and restore stability through techniques like internal fixation, replacement, and external fixation. Postoperative rehabilitation focuses on early range of motion while protecting the repair.
1) Fractures of the tibial plateau can be complex injuries involving both bone and soft tissues. Accurate reduction of the articular surface is important but other factors like alignment, ligament stability, and meniscal integrity also influence outcomes.
2) Surgical treatment may involve open reduction and internal fixation with plates and screws or less invasive options like percutaneous plating and hybrid external fixation to minimize soft tissue disruption.
3) Patient factors like age, comorbidities, and the specific fracture pattern help determine the best treatment which can range from non-operative management to internal fixation, external fixation, or a combination approach.
This document discusses the treatment of intertrochanteric fractures. It begins by distinguishing between intracapsular and extracapsular fractures, noting that treatment and results differ. Intertrochanteric fractures most commonly occur in the elderly due to age-related risk factors. Operative treatment is usually required and options include dynamic hip screws, proximal femoral nails, and angled blade plates. Implant choice depends on the stability of the fracture and proper placement is important for healing. Subtrochanteric fractures also require operative treatment due to deforming forces, with intramedullary nailing often used.

This document discusses pediatric femoral neck fractures. Key points:
- They are rare, accounting for less than 1% of pediatric fractures. Anatomy and blood supply make complications like avascular necrosis more common.
- Delbet classification includes 4 types based on fracture location. Type 1 is through the physis, Type 2 through the neck, Type 3 at the base of neck, and Type 4 is intertrochanteric.
- Treatment depends on type and stability but generally involves closed or open reduction and fixation or spica casting. Complications include avascular necrosis, coxa vara, premature physeal closure, and nonunion. Close follow up is needed due to risk of late complications.
This document discusses the anatomy, biomechanics, classification, diagnosis and treatment of shoulder instability. It begins with an overview of the normal shoulder anatomy including the glenoid, labrum, joint capsule, glenohumeral ligaments and muscles. It then covers types of shoulder instability, factors that influence recurrence, physical exam tests and classification systems. Treatment options discussed for anterior instability include modified Bankart repair and Latarjet procedure. Posterior instability is also reviewed.
This document discusses the principles of absolute and relative stability in fracture fixation, as well as locking compression plates. It describes how absolute stability aims to reduce strain below a critical level for primary healing without callus formation, while relative stability allows some motion and secondary bone healing through callus formation. Locking compression plates provide angular stability through locking head screws in the plate and bone, maintaining blood supply while providing fixation. They can be used for compression of reduced fractures or for splinting in multifragmentary fractures.
Thoracolumbar fractures account for 30-50% of spinal injuries and most commonly occur between T11-L1. They can cause neurological deficits affecting the spinal cord or cauda equina. Classification systems evaluate the injury pattern, neurological status, and integrity of posterior ligaments to determine appropriate treatment. Management may involve bracing, bed rest, or surgery depending on factors such as vertebral body height loss, canal compromise, and kyphosis. The goal of treatment is neural decompression, stabilization, and fusion to allow rehabilitation.
This document discusses the anatomy and physiology of the thoracolumbar spine and classifies different types of thoracolumbar spine injuries.

This document provides information on intertrochanteric fractures of the femur. It discusses the history, epidemiology, risk factors, anatomy, mechanisms of injury, classification systems, evaluation, and treatment options. Intertrochanteric fractures occur in the region between the greater and lesser trochanters and may extend into the subtrochanteric region. Treatment options include non-operative management with traction or operative fixation with devices like the dynamic hip screw, cephalomedullary nails, or plates. Classification systems help determine fracture stability and appropriate treatment.
1) Acetabular fractures are caused by high-energy trauma and require complex treatment due to the anatomy of the acetabulum and risk of joint instability.
2) Surgical treatment is indicated for fractures with over 2mm of displacement or less than 45 degrees of roof arc measurement, while non-operative treatment can be used for minimally displaced fractures or those with secondary congruence.
3) Surgical approaches like the modified Stoppa or Kocher-Langenbeck are selected based on the fracture pattern and aim to reduce and stabilize the displaced columns and walls with plates and screws to restore hip function.
Thoracic and lumbar fractures account for 30-50% of all spinal injuries. The majority occur between T11-L1 (thoracolumbar junction). They account for 50% of all spinal fractures, with an incidence of 4-5 per 100,000 people aged 18-35 years and occurring more in males. Neurological injuries occur in 25% of cases. Operative treatment is indicated for vertebral height loss over 40%, canal compromise over 40%, or kyphosis over 25 degrees. The goals of treatment are maximizing neurological recovery, maintaining spinal alignment, obtaining a healed and stable spine, and preventing deformity.

This document discusses thoracolumbar fractures of the spine. It begins by describing the anatomy of the spine and functional spinal units. It then discusses the physiological anatomy of the thoracic and lumbar spine. It describes the etiology, classifications including the Denis three-column theory and AO/MAGREL classification, clinical presentations, investigations including x-rays, CT and MRI, and classifications of spinal instability for thoracolumbar fractures.
Thoraco lumbar injuries can be categorized based on which spinal columns are affected. Injuries involving the middle column and at least one other column are considered unstable. Burst fractures involve failure of the anterior and middle columns and may require early stabilization, especially if they involve over 50% canal compromise, over 20 degrees of kyphosis, or over 45-50% canal compromise. Flexion distraction injuries can be categorized into types A through D depending on whether they involve bone or ligaments at one or two spinal levels.
Cervical Spine injuries by rakesh(presented on 11.11.10)Rakesh vallittayil
Cervical spine injuries can result from car accidents, falls, sports injuries, or violent acts. They can range from stable fractures where the spine structure is intact to unstable fractures where the spine cannot properly support and distribute weight. Imaging like x-rays, CT scans, and MRIs are used to diagnose and characterize fractures and other injuries like ligament damage. Treatment depends on the stability and extent of the injury, and may include immobilization with a collar, traction, or fixation surgery. Common cervical spine fractures include Jefferson fractures of C1, odontoid fractures of C2, Hangman's fractures, and bilateral or unilateral facet dislocations.
The document summarizes thoracolumbar spine injuries, including:
- Anatomy of the thoracic and lumbar spine regions which predispose the thoracolumbar junction to injury.
- Epidemiology showing these injuries most commonly affect segments T11-L2 and have bimodal age distribution.
- Classification systems including Denis, McCormack, and TLICS which evaluate morphology, neurology, and ligamentous integrity to determine treatment.
- Treatment principles aim to preserve neurology, minimize compression, stabilize the spine, and rehabilitate the patient either via non-operative or operative means.

It describes the common mechanisms of spinal injury including flexion, extension, axial loading, and rotation injuries. It outlines the aims of the radiologist in evaluating spinal trauma to define the extent and type of injury and guide management. The document then focuses on cervical spine trauma, providing details on imaging modalities, injury patterns, classifications of fractures and dislocations, and specific cervical spine injuries associated with different mechanisms. It also discusses thoracolumbar trauma including force vectors, stability considerations, basic fracture patterns, and specific injuries.
Three sentence summary:
This document discusses various types of spinal injuries and their appearances on CT imaging. It describes craniocervical injuries like Jefferson fractures and odontoid fractures. For thoracolumbar injuries, it outlines the AOSpine classification system including compression, burst, translation and distraction injuries. Key CT features are presented to identify and characterize spinal fractures and ligamentous injuries.
Fractures of the acetabulum can be caused by a blow to the side of the hip from a fall or force from the front of the knee in a car accident. They are classified based on the location and complexity, ranging from isolated fractures of one wall to fractures involving both columns. Treatment depends on the severity but may include traction, closed reduction, or open surgical repair to restore the ball and socket alignment and prevent long-term complications like avascular necrosis or osteoarthritis.
Elbow is the most common joint to dislocate in children. Posterior dislocation is most common.
Simple dislocations are those without fracture.
Complex dislocations are those that occur with an associated fracture
The document discusses cervical spine fractures, classifying them based on mechanism of injury including flexion, flexion-rotation, extension, etc. It describes common fracture types for each category such as wedge fractures for flexion and hangman's fractures for extension. It outlines key radiographic findings and treatments for fractures like unilateral facet dislocations and rotary atlantoaxial dislocations. Classification systems are discussed along with determining fracture stability and appropriate management.
Ankle fractures are common injuries that occur due to twisting of the ankle. Diagnosis is made using x-rays of the ankle. Treatment may be non-operative with a cast or operative with internal fixation depending on the fracture displacement and stability. Ankle anatomy includes the tibia, fibula, and talus bones. Fractures are classified based on the location of the fibula fracture and force applied at injury. Imaging helps evaluate fracture pattern and stability while manual stress tests assess ligament integrity. Management depends on fracture and ligament involvement, with goals of anatomical reduction and stable fixation.
1. Proximal femur fractures are divided into femoral head, femoral neck, and extracapsular fractures based on location. Accurately classifying the fracture type guides surgical management.
2. Femoral neck fractures occur through the intra-capsular part of the femoral neck. They are classified using the Garden or Pauwel's classifications which determine stability and treatment approach.
3. Intertrochanteric fractures occur between the greater and lesser trochanters. Younger patients often experience high-energy injuries while the elderly commonly sustain them from falls. Treatment depends on the Evans classification and stability.
Imaging of atlanto occipital and atlantoaxial traumatic injuriesSumiya Arshad
This document discusses imaging of injuries to the craniocervical junction (CCJ). It begins by reviewing the anatomy of the CCJ, including bones and ligaments. It then describes classifications of CCJ injuries and how CT and MR imaging can identify relevant injuries and clinical effects. Specific injuries covered include atlanto-occipital dissociation, occipital condyle fractures, fractures of C1 with transverse ligament rupture, and atlantoaxial distraction or rotatory deformity from alar ligament tears. Thin-slice CT is recommended for initial evaluation, while MR helps evaluate soft tissues and rule out spinal cord injury. Proper classification of CCJ injuries guides management of unstable or complex cases.
The document discusses ankle fractures, providing information on ankle anatomy, classification systems, clinical features, imaging, treatment, and complications. It describes the ankle joint as composed of the tibia, fibula, and talus bones. Two common classification systems are described - the Weber system categorizes fractures by the location of the fibular fracture in relation to the syndesmosis, while the Lauge-Hansen system depends on the mechanism of injury. Clinical features may include pain, swelling, limited movement, and neurovascular issues. Imaging includes x-rays and sometimes CT or MRI to evaluate bone and soft tissue injuries. Treatment involves initial stabilization followed by casting or surgery to restore anatomy, with goals of preventing post-traumatic arthritis
Fractures and dislocations of the spine most commonly occur in young people and can result in spinal cord injuries. In the US, there are 250,000 to 400,000 individuals living with spinal cord injuries or spinal dysfunction. Spinal fractures occur mostly due to accidents and industrial injuries, with the incidence proportionate to vehicles and construction. Early assessment of spinal stability and investigation via imaging can help determine the nature and severity of injuries. Management involves immobilization, rehabilitation, and may require surgical stabilization or decompression to relieve pressure on the spinal cord.
This document provides information on cervical spine trauma. It discusses:
- Common levels of cervical spine injury being C2, C6, and C7.
- Classification systems for fractures of the atlas, dens fractures, and subaxial cervical fractures.
- Treatment approaches depending on the fracture type, including non-operative treatment with collars or halos and surgical stabilization with techniques like anterior or posterior fusion.
- Key anatomy and biomechanics relating to mechanisms of injury for various fracture patterns.
Spinal trauma can result from automobile accidents and sports activities. Approximately 20% of spinal fractures are associated with fractures elsewhere in the body. Spinal cord injuries occur in 10-14% of spinal fractures and dislocations, with higher rates of neurological damage when fractures affect both the vertebral body and neural arch. Flexion is the most common mechanism of spinal injury. Fractures are most common in the lower cervical and upper thoracic regions. Imaging plays a key role in evaluating spinal trauma and classifying fracture patterns.
1. Hip dislocations are caused by high-energy trauma and often involve other injuries. They damage the blood supply to the femoral head, increasing the risk of complications like avascular necrosis.
2. Closed reduction under anesthesia is usually attempted first to restore blood flow, with the goal of early reduction to reduce risks. Surgery may be needed for irreducible or unstable dislocations or those with
