Fracture Fixation Techniques: ORIF, Plates and Nails

What Is Fracture Fixation?

Internal fixation places an implant within the body to maintain the reduction. External fixation uses percutaneous pins or screws connected to an external frame. External fixation may be temporary when soft-tissue injury or the patient’s condition makes immediate definitive internal fixation unsuitable, and it may be definitive in selected cases.[1][2]

The required reduction and stability depend on the fracture. AO guidance describes compression plating for two-part fractures that can be compressed, while bridge plating restores the length, alignment, and rotation of the main fragments and leaves the intermediate fracture zone relatively undisturbed.[3][4]

What does ORIF mean?

Open reduction and internal fixation, or ORIF, describes an open reduction followed by internal fixation. In an open reduction, the fracture is exposed through an operative approach before it is reduced. Internal fixation may also follow a closed or percutaneous reduction, so not every nail, screw, or plate fixation should automatically be labelled ORIF.[1][5][6]

ORIF describes the reduction approach rather than one specific implant. Plates and screws are common internal-fixation devices, and rods or nails may also be used when the fracture has been reduced through an open approach.[1]

Absolute Stability and Relative Stability

Absolute stability

Absolute stability aims to abolish interfragmentary motion. AO describes compression plating as a method for two-part fracture patterns in which the fragments can be compressed; the plate may generate compression through eccentric placement of conventional screws, and lag screws may supplement fixation when the fracture orientation permits.[3][7]

When operative fixation is selected, absolute stability is generally associated with accurately reduced, compressible fracture components. This does not mean that every simple fracture or articular fracture requires surgery or compression plating.[3][7]

Relative stability

Relative stability permits controlled interfragmentary movement and is associated with secondary healing and callus formation. AO bridge-plating guidance describes the plate as an extramedullary splint: the main fragments are fixed while the intermediate fracture zone is left untouched, with restoration of length, alignment, and rotation.[4][7]

Intramedullary nails and external fixators can also provide constructs in which stability depends on implant configuration, fracture pattern, and locking or frame design. For intramedullary nails, proximal and distal interlocking screws improve rotational control and are required for length stability in multifragmentary patterns. For external fixation, frame construction affects stiffness and stability.[2][8]

The intended stability should therefore match the fracture pattern, reduction goal, and planned construct. “Absolute” and “relative” describe mechanical strategies; they are not a universal ranking of one technique over another.[3][4][7]

Main Fracture Fixation Techniques

Plate and screw fixation

AO describes four principal ways in which a plate may function: protection or neutralisation, compression, bridging, and buttress or antiglide fixation. These terms describe how the plate is being used, not a particular plate brand or shape.[7]

Compression plating

A compression plate produces compression at the fracture site to provide absolute stability. AO describes this strategy for two-part fracture patterns in which the fragments can be compressed and notes that compression plating requires an open procedure.[3][7]

Protection or neutralisation plating

A protection or neutralisation plate protects a lag-screw fixation from bending and rotational forces. The lag screw produces interfragmentary compression, while the plate increases construct stability against additional loading.[7]

Bridge plating

A bridge plate spans a multifragmentary zone as an extramedullary splint. The main proximal and distal fragments are restored to the required length, alignment, and rotation, while direct manipulation of intermediate fragments is minimised to preserve their soft-tissue attachments and blood supply.[4][7]

Buttress or antiglide plating

AO describes buttress plates for selected partial-articular fractures and metaphyseal shear or split patterns. They may supplement lag-screw fixation and must be positioned and contoured so that the plate provides the intended buttress or antiglide effect.[7]

Locking and non-locking screws

A conventional screw inserted in neutral mode pulls the plate toward the bone. A locking screw engages the plate to create a fixed-angle connection, so the plate is not pressed against the bone in the same way. Locking screws cannot be inserted eccentrically to generate dynamic compression in the manner of conventional screws.[7]

Locking technology does not correct a poor reduction or an unsuitable plate position. Fracture reduction, plate function, screw trajectory, bone quality, and construct design remain fracture-specific technical considerations.[7]

Intramedullary nailing

An intramedullary nail is inserted into the medullary canal. AO describes intramedullary nailing for metaphyseal and diaphyseal fractures, while hip-fracture guidelines specify cephalomedullary nails for selected proximal-femoral patterns.[8][9][10]

After the fracture is reduced, the nail can restore axial alignment and resist angulation. Without locking, rotational control may be unreliable. Proximal and distal interlocking screws enhance rotational stability, and AO states that both are required for length stability in multifragmentary fractures.[8]

Reduction is an essential part of nailing. AO advises restoring length, angulation, and rotation before reaming and nail insertion. Reduction may be achieved with traction, percutaneous aids, temporary external fixation, or open reduction when less-invasive methods are unsuccessful or unsuitable.[8]

Editorial preparation framework: Before a nailing case, review the fracture-specific entry point, patient position, fluoroscopic access, reduction aids, guide-wire path, reaming plan, nail dimensions, locking method, and alignment checks. This is a learning framework derived from AO’s nailing sequence, not a universal operative protocol.[8]

Sliding hip screw and cephalomedullary nail fixation

A sliding hip screw, often called a dynamic hip screw or DHS, is an extramedullary implant. A cephalomedullary nail is an intramedullary implant. Device selection should not be reduced to a universal “nail versus plate” rule because recommendations vary by fracture pattern and guideline scope.[9][10]

The AAOS Management of Hip Fractures in Older Adults guideline is based on studies of adults aged 55 years and older. It recommends either a sliding hip screw or a cephalomedullary device for stable intertrochanteric fractures. It recommends a cephalomedullary device for subtrochanteric or reverse-obliquity fractures and for unstable intertrochanteric fractures.[9]

NICE guidance for adults with hip fracture in the UK recommends an extramedullary implant such as a sliding hip screw in preference to an intramedullary nail for trochanteric fractures above and including the lesser trochanter, except reverse-oblique fractures. NICE recommends an intramedullary nail for subtrochanteric fractures.[10]

These recommendations should be read within their stated populations and health-system contexts. They do not support a claim that either device is universally superior.[9][10]

For proximal-femoral fixation, AO describes procedure-specific AP, axial, and lateral fluoroscopic views. The required views are used to assess reduction, guide-wire position, alignment, and implant position; the exact imaging sequence depends on the construct and anatomy.[11]

External fixation

External fixation uses percutaneous pins or screws connected to an external frame. AO describes the modular external fixator as well suited to temporary use because it can be applied rapidly and adjusted later. External fixation may also be continued as definitive fixation in selected circumstances.[1][2]

Pin placement is a central safety consideration. Pins should be inserted through region-specific safe zones, avoid traumatised soft tissues, and not enter a joint cavity. When the frame is temporary, pins should also be positioned so that they do not interfere with planned definitive fixation.[2]

The frame is reduced to restore the required length, alignment, and rotation, and reduction is checked with imaging. A joint-spanning frame may be useful for periarticular injuries, but AO advises conversion to fixation that permits joint movement as soon as practical because prolonged joint spanning creates a risk of long-term stiffness.[2]

Pin-track infection and pin loosening are recognised external-fixation problems. AO notes that pin-track infection can complicate conversion to internal fixation and may increase the risk of intramedullary infection if a reamed nail is subsequently used through an infected field.[2]

Provisional fixation, wires, and cerclage compression constructs

Reduction aids may include clamps, percutaneous reduction instruments, temporary external fixation, provisional plates, lag screws, and Kirschner wires. Their placement should be planned so that they do not obstruct the definitive implant or create avoidable risk to nearby structures.[7][8]

AO defines a tension band as a device placed on the tension side of an eccentrically loaded fracture to convert tensile load into compressive load. For the principle to work, the fracture must be eccentrically loaded and the compression cortex must be stable.[12]

Comminution or a fracture gap on the compression side can increase implant strain and lead to fatigue failure. Poor bone quality can contribute to fixation failure through implant pullout. AO also cautions that “tension band” may be an inaccurate term for some periarticular constructs and uses cerclage compression wiring for selected simple fracture configurations in good-quality bone.[12]

Indications, Limitations, and Contraindication Language

A principles article should not present one universal contraindication list for all fracture-fixation methods. Contraindications and alternative strategies are fracture-, patient-, anatomy-, implant-, and protocol-specific. The following points are source-supported limitations or reasons that another strategy may be selected; they are not a complete prescribing rule.[2][3][8][9][10][12]

• Compression plating: AO describes it for two-part patterns that can be compressed and notes that it requires an open procedure. A fracture that cannot be reduced and compressed using the intended construct does not fit that described technique.[3]

• Bridge plating: AO describes it for multifragmentary fractures in which main-fragment length, alignment, and rotation can be restored while the intermediate zone is left relatively undisturbed.[4][7]

• Intramedullary nailing: AO identifies existing hardware, a small medullary canal, and soft-tissue concerns as reasons another fixation method may be chosen. Entry point, canal dimensions, reduction, and implant-specific requirements also need to be compatible with the planned nail.[8]

• External fixation: Safe pin corridors must be available, pins must avoid joints and critical structures, and temporary pin positions must not compromise later fixation. Active pin-track infection is an important concern when conversion to internal fixation is planned.[2]

• Tension-band or cerclage compression constructs: The tension-band principle requires eccentric loading and stable support on the compression side. Comminution, a persistent gap, or poor bone quality may increase the risk of fatigue failure or pullout.[12]

• Sliding hip screw versus cephalomedullary nail: The cited guidelines make pattern-specific recommendations; they do not establish one implant as appropriate for every trochanteric or subtrochanteric fracture.[9][10]

For an actual case, use fracture-specific guidance, the selected implant’s current technical documentation, local protocols, and direct consultant supervision.[2][7][8][9][10]

Open Fractures and Staged Fixation

Open-fracture care extends beyond implant selection. In the BOAST standard for open fractures of long bones, the hindfoot, or midfoot, initial management includes prompt intravenous prophylactic antibiotics, repeated neurovascular assessment, realignment and splinting, controlled wound handling, and coordinated orthoplastic care. That BOAST document excludes the hand, wrist, forefoot, and digits from its formal scope, although it states that similar principles may be used locally.[13]

Within that UK standard, intravenous prophylactic antibiotics should be administered as soon as possible, ideally within one hour of injury. BOAST also gives injury-specific debridement windows: immediately for highly contaminated wounds or associated vascular compromise, within 12 hours for other high-energy open fractures, and within 24 hours for other low-energy open fractures.[13]

NICE recommends a combined orthopaedic and plastic-surgery approach for wound excision, fixation, and coverage of open fractures of the long bone, hindfoot, or midfoot. It recommends fixation and definitive soft-tissue cover at the same time as wound excision when the relevant orthoplastic list permits, or within 72 hours of injury if definitive cover cannot be performed at wound excision. When internal fixation is used, NICE recommends definitive soft-tissue cover at the same time.[14]

BOAST similarly states that definitive soft-tissue closure or coverage should be achieved within 72 hours if it cannot be performed at debridement, and that definitive internal stabilisation should be undertaken only when it can be followed immediately by definitive soft-tissue cover.[13]

These are UK pathway standards with defined injury scopes. They should be presented as such and should not replace the trauma-system and antibiotic protocols applicable to the treating institution.[13][14]

Fracture Fixation Preparation Workflow

Editorial preparation framework: The sequence below is a structured learning aid synthesized from AO plating, nailing, external-fixation, and imaging references. It is not a universal operative checklist. Procedure-specific guidance takes priority.[2][7][8][11]

1. Define the fracture problem

Review the available imaging, fracture morphology, displacement, comminution, articular extension, open-fracture status, soft-tissue injury, and associated neurovascular concerns. Use a classification only when it adds useful communication or planning information.[2][7][8][13]

2. State the reduction objective

Identify which components need direct reduction and which can be managed indirectly. For compression fixation, determine whether the fragments can be accurately reduced and compressed. For a bridge construct, define the required length, alignment, and rotation of the main fragments.[3][4]

3. State the intended stability

Record whether the construct is intended to provide absolute or relative stability and confirm that the planned plate mode, nail locking, or frame configuration is consistent with that goal.[2][7][8]

4. Review the anatomy at risk

Map the structures relevant to the approach, reduction instruments, screw or pin trajectories, and implant placement. External-fixation pins, for example, require region-specific safe corridors and must avoid joints, nerves, vessels, tendons, and muscles.[2]

Osgenic’s 3D surgical anatomy is designed to place anatomy in procedure-specific positions and clinical context.[24]

5. Confirm positioning and imaging access

Before sterile preparation, confirm that the table, patient and limb position, traction or reduction equipment, and image-intensifier access permit the procedure-specific views. AO’s proximal-femur guidance illustrates why different views may be needed to assess reduction and implant position in three dimensions.[11]

6. Rehearse a high-level sequence

A useful learning sequence is: positioning, imaging setup, approach, reduction, provisional fixation, definitive fixation, final imaging, closure, and postoperative plan. This is an editorial sequence, not a substitute for the selected procedure’s operative steps.[2][7][8][11]

7. Identify method-specific failure points

Examples include loss of length or rotation during bridge plating, fracture displacement during incorrectly applied compression, failure to maintain reduction during nail passage, unsafe pin or screw placement, obstruction of the definitive implant by provisional fixation, and inadequate procedure-specific imaging.[2][7][8][11]

Intraoperative Imaging and Final Checks

Imaging requirements are procedure-specific. For proximal-femoral fixation, AO describes AP, axial, and lateral views and notes that the axial view provides information about guide-wire or implant position within the head-neck fragment that the lateral view may not reliably show.[11]

Many fracture-fixation procedures therefore use more than one projection or a specialised view, but this should not be converted into a universal rule about a fixed number of images. The required views depend on the anatomy, fracture, and implant.[2][11]

Editorial final-check framework — apply only where relevant:

• reduction of the component or joint surface that required direct restoration;

• length, coronal alignment, sagittal alignment, and rotation;

• plate, nail, or frame position;

• screw, pin, guide-wire, or blade trajectory and length;

• absence of unintended joint penetration;

• completion of required proximal and distal locking;

• stability of the intended construct; and

• soft-tissue and neurovascular status.

These endpoints are assembled from method-specific AO and BOAST guidance; not every item applies to every fracture.[2][7][8][11][13]

Risks and Technical Pitfalls

Risk depends on the injury, soft-tissue damage, patient factors, fixation method, and technical execution. The following are examples rather than a universal complication list.[2][7][8][15][25]

Risks associated with operative internal fixation

AAOS patient guidance for adult forearm fracture surgery identifies infection, nerve or blood-vessel injury, nonunion, loss of fixation or implant breakage, stiffness, and symptomatic implants as possible complications in that fracture context. These examples should not be presented as identical in incidence or relevance across all bones and fixation methods.[15]

BOAST notes that comorbidities, local soft-tissue injury, open wounds, and implants increase vulnerability to fracture-related infection in surgically managed fractures. This supports careful infection-prevention and surveillance language but does not justify claiming that infection can always be prevented.[25]

Plating-specific pitfalls

AO describes loss of compression or fracture displacement when compression principles, plate position, or fracture geometry are unsuitable. It also warns that an unaddressed fracture gap can contribute to delayed union and fatigue failure, and that screws near a joint can penetrate the articular surface if position and length are not checked.[3][4][7]

Intramedullary-nailing pitfalls

AO emphasises restoration of length, angulation, and rotation before reaming and nail insertion. Inadequate reduction can lead to deformity, and insufficient locking can leave a construct without reliable rotational or length stability in the patterns for which locking is required.[8]

External-fixation risks

Recognised external-fixation problems include pin-track infection, pin loosening, injury from unsafe pin placement, and long-term joint stiffness when a joint-spanning frame is maintained longer than practical. Pin-track infection can also complicate later conversion to internal fixation.[2]

Tension-band or cerclage-compression risks

A construct may fail by implant fatigue if the compression side lacks support because of comminution or a fracture gap. Poor bone quality may contribute to fixation failure through implant pullout.[12]

Technical preparation should focus on potentially modifiable contributors, not imply that every complication is preventable. These contributors may include an inaccurate reduction, an unsuitable stability strategy, poor implant or pin position, failure to obtain required imaging, or unnecessary disruption of the fracture-zone soft tissues.[2][7][8][11]

Postoperative Planning

This hub does not prescribe universal weight-bearing, range-of-motion, antibiotic, imaging, or rehabilitation schedules. Aftercare is fracture- and construct-specific, and external-fixation care also requires attention to pin sites and plans for frame retention, adjustment, or conversion.[2]

The postoperative plan should therefore be taken from the operative surgeon’s instructions, fracture-specific guidance, local protocols, and the patient’s clinical circumstances rather than from a generic fixation timeline.[1][2]

Fracture Fixation Learning With Osgenic

Osgenic’s content library includes fracture-fixation and related orthopaedic-trauma resources. Its orthopaedic residents page describes procedure-focused preparation using clinically relevant anatomy, surgical steps, and practical considerations.[19][26]

For departments and training organisations, the residency programs page describes institutional access to procedure-focused resources and 3D surgical anatomy. These are first-party descriptions of Osgenic’s educational offering, not evidence that the platform changes clinical outcomes.[27]
