Introduction 

“The perfect restoration of the articular surface and associated osseous 

architecture” was the goal set forth by R. Judet and E. Letournel in their surgical 

treatment of fractures of the pelvis and the acetabulum. 

However, before surgical intervention in a fractured acetabulum can be accepted 

as a means of treatment, accurate diagnosis based on radiology is essential. As in 

other conditions, classification also aids in the accurate understanding of these 

sometimes complex fractures. 

No one surgical approach is applicable for all acetabulum fractures. After 

examination of the plain films as well as the CT scan the surgeons should be 

knowledgeable of the precise anatomy of the fracture they are dealing with. A 

surgical approach is selected with the expectation that the entire reduction and 

fixation can be performed through the surgical approach. 

The Letournel classification was first published in 1961. Apart from some minor 

early modifications, it has since remained unchanged and is now the most widely 

used classification system for acetabular fractures. This classification proposes the 

division of the various fracture types into two large groups: 

Elementary Fractures comprise those in which a part or all of one or both 

columns supporting the acetabulum has been detached by a single fracture line. 

The five elementary fracture types are: 

- Fracture of the posterior wall 

- Fracture of the posterior column 

- Fracture of the anterior wall 

- Fracture of the anterior column 

- Transverse fracture 

Associated Fractures comprise those in which two or more elementary patterns 

are combined. The five associated fracture types are: 

- T-shaped fracture 

- Posterior column and posterior wall fracture 

- Transverse and posterior wall fractures 

- Anterior column or anterior wall with posterior 

hemi-transverse fracture 

- Both-column fracture 

Judet and Letournel concluded early on the most important factor in a successful 

operation was a thorough pre-operative three-dimensional understanding of the 

X-Rays and fracture pattern. The same is true today. The surgeon’s knowledge, 

skill and dedication remain the primary determinants of the patient’s outcome, 

and the Stryker Pelvic & Acetabular Fracture Treatment Solutions seek to facilitate 

this.

Rationale for Stryker Pelvis & Acetabulum 

Products 

Matta Pelvic System (MPS) 

The Matta Pelvic System (MPS) is designed to address all fractures of the 

acetabulum and pelvis. The shape, material properties, plate malleability and hole 

spacing of the plates take into account today’s physician’s need for sufficient fatigue 

strength, excellent transfer of loading forces and a standardized operative technique 

with broad applicability. The current set also includes a variety of clamps and 

reduction aids that are most valuable in pelvic and acetabular reduction technique. 

External Fixation 

Hoffmann II External Fixation plays a definitive role in the treatment of unstable 

pelvic fractures using the device as provisional fixation. In contrast to internal 

fixation, this method has three potential advantages: ease-of-use, versatility and 

potential to increase OR efficiency. 

Apex Pin Fixation 

Solid pin fixation is essential for effective external fixation frames. The Apex Pin 

uses advanced thread geometry designed to yield outstanding cutting performance 

and excellent pin fixation. 

Asnis Screw Fixation 

Asnis III 6.5mm or 8.0mm cannulated screws can be utilized in surgical stabilization 

of sacroiliac joint disruption and/or sacral fractures using a minimally invasive 

approach. 

HydroSet 

HydroSet injectable HA bone void substitute can be utilized in comminuted 

posterior wall fractures as an effective osteoconductive and osteointegrative material, as 

well as to help support pelvic bone fragments.

Precautions & Contraindications for 

Stryker Pelvis & Acetabulum Products 

Precautions* 

Stryker Osteosynthesis systems have 

not been evaluated for safety and 

compatibility in MR environment 

and have not been tested for heating 

or migration in the MR environment, 

unless specified otherwise in the product 

labeling or respective operative 

technique. 

Contraindications* 

The physician’s education, training 

and professional judgment must 

be relied on to choose the most 

appropriate device and treatment. 

Conditions presenting an increased 

risk of failure include: 

• Any active or suspected latent 

infection, or marked local 

inflammation in or about the 

affected area. 

• Compromised vascularity that 

would inhibit adequate blood 

supply to the fracture or the 

operative site. 

• Bone stock compromised by 

disease, infection or prior implantation 

that cannot provide adequate 

support and/or fixation of the 

devices. 

• Obesity. An overweight or obese 

patient can produce loads on the 

implant that can lead to failure 

of the fixation of the device or to 

failure of the device itself. 

• Patients having inadequate tissue 

coverage over the operative site. 

• Implant utilization that would 

interfere with anatomical structures 

or physiological performance. 

• Any mental or neuromuscular 

disorder that would create an 

unacceptable risk of fixation failure 

or complications in postoperative 

care. 

• Other medical or surgical 

conditions that would preclude the 

potential benefit of surgery. 

• Material sensitivity, documented or 

suspected. 

* Please refer also to Precautions and Contraindications listed in the respective 

Instructions for Use: V15011, V15013, V15034, 90-01616.

Assessment of Pelvic Ring and Acetabulum 

Fractures 

The evaluation of a pelvic injury has to be based on repeated checks of the patient’s 

vital parameters, a detailed clinical examination and a structured radiographic 

evaluation. Emergency decisions can usually be based on a pelvis AP X-Ray, 

whereas the detailed classification is assigned after additional oblique projections.

20

Matta Pelvic System – Plate Bending 

The plate must be shaped correctly to fit with precision to the reduced contour of the pelvis or the acetabulum. 

The fitting of the plate on the bony 

surface should be as precise as possible 

so the insertion of screws will not 

cause the fragments to change position 

(Figure 1). 

During plating and screw insertion, 

it is always the bone that is drawn 

toward the plate, not the plate 

toward the bone (Figure 2). 

In certain instances it may be 

advantageous to contour the plate 

to a slight mis-match with the bone. 

Subsequent insertion and tightening 

of the screws causes the plate to 

manipulate the bone, therefore aiding 

in obtaining or maintaining the 

reduction. 

Figure 1 – Correct 

If the plate fits precisely. 

Figure 2 – Incorrect 

When tightening the screws, the fragment will be drawn towards the plate. 

21

Matta Pelvic System – Plate Bending 

For a plate to apply perfectly on a bone, it must be possible to shape it in all directions: 

• Curve it to adapt to the shapes of the 

iliac crest or the upper aspect of the 

pelvic brim, or to make it possible 

to span a fragment of the posterior 

wall or posterosuperior wall, along its 

main axis (Figure 3a, 3b). 

• Bend it along its main axis 

(Figure 4a, 4b). 

• Twist it along its main axis, to give it a 

helicoidal shape (Figure 5a, 5b). 

Curving should always be performed 

first, since it is very difficult to curve 

the plate after a main axis bend or twist 

has been made. 

Figure 3a 

Figure 4a 

Figure 5a 

Figure 3b 

Figure 4b 

Figure 5b 

It is an important fact that the plate 

must be bent, as far as possible, in the 

spaces between the holes, so as to alter 

them as little as possible (Figure 6). 

It is a well-known fact that rectangular 

plates do not bend in a regular fashion 

but rather at their holes (Figure 7). 

Sherman type plates with equal hole 

spacing and narrowing between the 

holes, are best adapted to such shaping 

and allow for a more precise adaptation 

to the pelvic contours. 

Figure 6 

Figure 7 

22

Matta Pelvic System – Screw Fixation 

3.5/4.5mm MPS Screws used with MPS Plates 

The 3.5mm self-tapping cortical screws 

are the recommended screws for plate 

fixation and are best adapted to the 

pelvic bone. The 4.5mm cortical screw 

is often too large and its voluminous 

head creates a slight prominence above 

the plates, which may lead to soft tissue 

irritation in certain applications. 

Therefore, these screws should only 

be used to fix a plate in exceptional 

cases (symphysis pubis fixation), as 

when a smaller screw does not 

get sufficient purchase. 

Furthermore, the plate holes are 

designed to accept 3.5mm screws 

inserted at extreme angles, up to 35 o 

in all directions. 

This capability is essential, as it must 

be possible to avoid penetrating the 

hip joint or to be able to drive a screw 

obliquely in the area of the iliac bone, 

avoiding a previously inserted, isolated 

screw. 

35º 

4.5mm cortical or 6.5mm cancellous 

screws used as Lag Screws: 

• Screw 1: 

From the crest of the anterior 

border into the iliac wing. 

• Screw 2: 

From the anteroinferior iliac 

spine, passing 1 or 2cm above the 

acetabulum (length 100 –120mm). 

• Screw 3: 

Along the axis of the anterior 

column, starting from the 

posterior aspect of the iliac wing 

pillar approx. 3-4cm above the 

acetabulum. 

This screw is very useful to 

secure a transverse fracture or 

an anterior column, through an 

extended ilio–femoral approach. 

• Screw 4: 

From posterior to anterior part of 

the iliac wing. 

• Screw 5: 

From posterior superior iliac spine 

to anterior part of the iliac wing to 

reduce a sacroiliac joint fracture 

dislocation. 

• Screw 6: 

Along the axis of the posterior 

column. 

For each of these lag screw insertions, 

it is essential to drill intermittently, 

step-by-step, and change the direction 

of the drill if you feel penetration of a 

cortex. 

Remain in the correct axis and 

advance the drill as far as possible. 

23

Matta Pelvic System – Screw Fixation 

Independent Interfragmentary 

Compression 

Often, independent (isolated) 

interfragmentary lag screws are used in 

conjunction with pelvic and acetabular 

fracture fixation. The screw thread 

takes no purchase in the near fragment 

because the screw has a shaft with 

no thread and/or the drill hole in the 

near fragment is equal to the outside 

diameter of the screw. 

Therefore, the cortex in the near 

fragment has to be overdrilled to create 

a “gliding” hole. Overdrilling the cortex 

in this manner allows the screw thread 

to take purchase in the bone of the 

opposite fragment. 

Drill Guides 

Use the Double Drill Guide REF 

702417 and the 4.5mm Drill or Double 

Drill Guide REF 702418 and Drill 

3.5mm for screws 3.5mm to overdrill 

the near cortex. Insert the opposite side 

of the relevant Drill Guide into the 

pre-drilled hole for precise axial 

alignment and use the corresponding 

drill for the corehole of the screw. 

This procedure should prevent the loss 

of reduction and fixation during screw 

insertion. 

24

Matta Pelvic System – Reduction Instruments 

The Matta Pelvic Systems forceps 

and other reduction instruments are 

designed for use with the irregular, 

large and flat bony surfaces of the 

pelvic region. 

The angles and length of the jaws 

are designed to accommodate the 

innominate bone from the crest to 

the pelvic brim and to provide 

flexibility for various surgical 

approaches. 

Reduction of acetabular fractures 

are best performed on the othopaedic 

extension table allowing distal and 

lateral traction. 

Reduction Forceps with Points 

Faraboef Forceps 

702926 – L130mm 

702927 – L200mm 

These forceps can be applied directly

These two oblique forceps are designed 

so that the handles angle away from 

both the surgeon`s sight line and 

critical soft tissue structures. The sharp 

points provide a secure hold on the 

pelvic surfaces, while the balls prevent 

penetration of bone with a thin cortex. 

These two forceps have been designed 

to be used with either 3.5mm or 4.5mm 

screws (3.5mm version available in left 

or right option). Screws inserted on 

the opposite side of the fracture allow 

considerable reduction forces and 

manipulation in all three planes. 

For easier reduction, there are times 

when only one screw is inserted, 

requiring the application of one jaw of 

the Verbrugge forceps. The other jaw 

takes direct hold on another part of the 

bony surface. 

Example: The angle of the greater 

sciatic notch.

This long forceps with threepointed 

ball tips allow reduction of 

perpendicular fractures. The long 

handles provide increased leverage for 

difficult reductions. These forceps are 

also available in a 1x1 jaws version. 

Two sizes are available to enable better 

soft-tissue retraction. 

This reduction instrument is used as a 

pusher with pointed ball tip to reduce 

bone fragments. 

To distribute the reduction forces over 

an increased area, the Spiked Disc can 

be clipped onto the ball tip.

External Fixation Pelvic Frame 

Hoffmann II MRI External Fixation System offers rapid application in times of hemodynamic compromise with the ability to 

access the abdomen and pelvic viscera for secondary procedures. 

External Fixation is most appropriate for open-book pelvic fractures in which the posterior structures are at least partially 

intact, or lateral compression injuries with internal rotation of the hemipelvis.

Hoffmann II MRI - Pin Placement Techniques 

The insertion of two K-wires, 

one on the medial side and one on 

the lateral side of the iliac wing, 

provides an accurate targeting method. 

They identify both borders of the crest 

and plane of the ilium toward the 

acetabular roof, helping to ensure safe 

and correct placement of the Apex pins 

between the two tables of the ilium. 

Avoid penetration of the medial cortex 

in order to limit pelvic viscera risk. 

Illiac Crest Pin Placement. 

Illiac Crest and Inferior Illiac spine combined Pin Placement. 

Due to the supraacetabular bone mass 

being significantly thicker, a frame 

construct mounted on a single Apex 

pin offers improved rigidity. Care has 

to be taken not to injure the lateral 

femoral cutaneous nerve during pin 

insertion. The orientation of the Apex 

pin can be perpendicular to the body 

axis or directed somewhat cephalad, 

depending on the location of the 

starting point in relation to the greater 

sciatic notch.

Apex Pin Fixation 

Technical Details – 

Self-Drilling/Self-Tapping Apex Pin 

Pin Design 

The self-drilling tip of the Apex Pin 

acts like a new, sharp drill bit every 

time, and therefore, pre-drilling is 

not necessary. Combined with unique 

cutting geometry, this one-step 

procedure allows the pin to maintain a 

reduced insertion temperature due to 

decreased friction. 

A double helical flute creates a 

homogeneous thread profile that 

transports bone chips out of the drill 

hole for improved pin/bone interface. 

The U-shaped thread maximizes contact 

with the bone and controls stress 

distribution on the pin/bone interface 

by optimizing radial tension. 

The highly advanced cutting geometry 

allows for more precise pin insertion 

with reduced insertion time and 

temperature for optimal performance. 

The cylindrical thread is designed for 

good bone purchase, and pull-out 

resistance 1, 2, 3 , and offers the possibility 

to backing out the pin without 

compromising fixation.

Acetabular Articular Fragments Augmentation 

with HydroSet 

Fractures of the posterior wall of the acetabulum comprise one-fourth to one-third 

of all acetabular fractures, representing the most common pattern of fracture of the 

acetabulum.* 

In fractures with intra-articular comminution and intercalary osteochondral 

fragments, one can use HydroSet calcium phosphate cement, an injectable, 

sculptable bone substitute to help support bone fragments during the surgical 

procedure**. 

It is recommended that the femoral head is used as a template to orientate and to 

reduce the different articular fragments. 

Features 

Excellent wet-Field Characteristics 

Fast Setting 

Isothermic 

Injectable or Manual Implantation 

Osteoconductive 

Radiopaque 

Benefi ts 

Decreases potential for waiting time. 

Limited waiting time. 

No damaging heat is released to the 

surrounding tissue. 

Greater number of options for the 

surgeon and the opportunity to sculpt 

HydroSet. 

The composition of hydroxyapitite 

closely matches that of bone mineral 

thus. 

Impenetrable by X-Ray. Visible under 

fluoroscopy.
