Pelvic Standard Instrument SetThe Pelvic Instrument Set has a wide range of standard instruments for screw insertion, plate adaptation (bending instruments) and fixation during reduction for preliminary and definitive stabilization of pelvic and acetabular fractures.
The complex anatomy of the pelvic ring and acetabulum involve complex surgical exposures and demands exact anatomical reduction to achieve positive functional results.
The AO and Synthes took this into consideration in develop-ing the Pelvic Implant and Instrument Sets.
Pelvic Implants and Instruments. A dedicated system for reconstructive pelvic and acetabular surgery.
Essential equipment for the surgical treatment of pelvic fractures
The Pelvic Implant and Instrument Sets contain a wide range of implants, reduction instruments, retractors and instru-ments for screw and plate fixation for the operative treat-ment of pelvic and acetabular fractures. All implants are available in 316L implant stainless steel, sterile and non ster-ile packaged.
Reconstruction Plate and Screw SetThe pelvic and acetabular low profile implants offer pre-shaped plate designs. Additional trays with locking compres-sion, wide angle (acetabular) and J-plates (pelvic brim) are also available. All plates can be three-dimensionally con-toured allowing them to be closely adapted to pelvic bone surfaces. Bending templates allow for easy manual adap-tation of the plates.

Pelvic Retractor SetA wide range of retractors (pelvic, Hohmann, sciatic nerve and malleable) within the Pelvic Retractor Set provide more options to aid the surgeon in achieving good visibility within the chosen approach.
Pelvic Reduction Instrument SetThe pelvic reduction forceps and other reduction instruments within the Pelvic Reduction Instrument Set are designed to aid the surgeon with fracture reduction of pelvic injuries.

Reconstruction PlatesOccasionally, pelvic osteosyntheses can be carried out using screws alone, but in the majority of cases lag screw fixations must be supplemented by one or more plates.
The bone surfaces in the pelvic region have a very complex topography. In order to achieve accurate fixation, the plates should be contoured to the bone surface. Poorly contoured plates can lead to fracture displacement when the screws are fully tightened through the plate.
The design of the reconstruction plates allow for contouring in all three planes.
Uniform cross-sectionImproved contourability

AO Principles
In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation:1, 2 Those principles as applied to the Pelvic Implants and Instruments are:
Anatomic reductionFracture reduction and fixation to restore anatomical relationships.
Stable fixationStability by screw only or screw and plate fixation, as the personality of the fracture and the injury requires. The products provide purchase for required compression and stability.
Preservation of blood supplyPreservation of the blood supply to soft tissue and bone by careful handling and atraumatic surgery. Use of surgical technique that minimizes disruption of soft tissue and pre-serves vascular blood flow for bone healing.
Early, active mobilizationEarly and safe patient mobilization. The implants, combined with AO technique, provide stable fracture fixation with minimal trauma to vascular supply. Plate features combined with AO technique create an environment for bone healing, expediting return to function.

Instruments for screw fixationScrew fixation of the pelvis requires the use of extra-long screws and corresponding instruments. The following instruments are part of the Pelvic Instrument Set:
– Extra-long 3-fluted calibrated drill bit – Extra-long taps, calibrated with depth markings – Extra-long screwdrivers (hexagonal and Stardrive) and
screwdriver shafts (hexagonal and Stardrive) – Extra-long depth gauge
Instruments – Standard
Bending instruments – The bending pliers should be used as the primary bending
instrument. – A smooth bend is best achieved by the introduction of
many small bends. – Bending irons, designed specifically for use with the
reconstruction plates, are also available.
Pelvic Implants and Instruments Surgical Technique DePuy Synthes 9
Bending templates Malleable bending templates are available for all reconstruc-tion plate shapes (straight, curved, J-shaped). These can be fi tted to the reduced bone and then a plate is shaped to fi t the template. This helps to avoid repeated plate bending, which can cause micro cracks, therefore weakening the plate.
The templates can also be used to determine plate lengths.
In-situ bending instruments – In-situ bending instruments allow precise intraoperative
adaptation of the pre-bent reconstruction plate to the bone anatomy.
– The in-situ bending and twisting handles with different tips (straight, 90°, 120°) allow use in different surgical approaches.

A wide range of malleable, blunt, spoon shaped, pelvic, Hohmann and sciatic nerve retractors provide more options to aid the surgeon with the chosen approach.
Instruments – Retractors
Pelvic Implants and Instruments Surgical Technique DePuy Synthes 11
Radiolucent retractorsRadiolucent retractors allow for the passage of x-rays without having to remove the instrumentation in order to visualize the implant underneath. Another advantage of these retractors is their light weight.
In an effort to accommodate the surgeon needs, Synthes has redesigned several retractors in aluminum, thus making them radiolucent.

Instruments – Reduction
Pelvic reduction forcepsThe pelvic reduction forceps are designed to maximize the potential of the ilioinguinal and Kocher-Langenbeck ap-proaches. The jaws of all the larger forceps are long enough to accommodate the innominate bone, from the iliac crest to the pelvic brim, and can be used without exerting excess pressure on the iliac vessels.
Pelvic reduction forceps are equipped with features to im-prove handling characteristics during reduction maneuvers. – Pointed-ball tips prevent penetration of bone with a
thin cortex. – Longer spikes with sharper points provide a secure hold
on the pelvic surfaces.
Increased selection of forceps, including – Handles and jaws of different lengths – Straight and oblique versions
Ball spikes with pointed ball tipThe straight ball spikes facilitate reduction of bone frag-ments. They feature a spike to reduce the risk of the instrument slipping off the bone and a pointed-ball tip to prevent penetration of bone with a thin cortex.
Round and rectangular disksDisks can be used in conjunction with the reduction forceps with pointed ball-tips or the ball spike instruments. In poor quality bone (osteoporotic), they can aid in distributing the applied forces over a larger surface area in effort to prevent iatrogenic or compression fractures.
Pelvic Implants and Instruments Surgical Technique DePuy Synthes 13
Pelvic reduction forceps for screwsAll forceps have been designed for use with 3.5 mm / 4.5 mm screws inserted on opposite sides of a fracture line, which allows the application of considerable reduction forces and manipulation in all three planes.
The large forceps have long handles for the transferal of large forces. The Farabeuf forceps can be either used with screws or as general bone forceps, i.e. to grasp and manipulate the iliac wing. – Jungbluth large (330 mm), small (250 mm),
for B 3.5 mm screws – Farabeuf medium (250 mm), small (190 mm),
for Cortex Screws B 3.5 and 4.5 mm
Reduction forceps with points These standard forceps can be applied directly to the bone’s surface, or be used with shallow drill holes or anchoring rings and hooks.
Medium and large bone hooksThe bone hooks are designed to allow the surgeon to mani-pulate the bone or bone fragments in order to ensure proper alignment and to achieve an anatomical reduction.

In-situ Plate Contouring
In-situ bending instruments adjust the pre-bent, reconstruc-tion plates on the bone to match relevant patient anatomy during a surgical procedure. Using this instruments helps decrease the surgical time by reducing the need for repeated cycles of plate positioning and removal until the plate has been sufficiently shaped.
IndicationsThe instruments are intended for use with the following plate systems: – Reconstruction Plates 3.5 with low profile (straight,
curved and J-shaped) – Reconstruction Plates 3.5 with wide Angle – DCP Reconstruction Plates 3.5, straight and curved
ContraindicationsPlates with locking and coaxial combi-holes. In particular: – Locking Reconstruction Plates 3.5 – Pubic Symphysis Plates 3.5 – Spring Plates 3.5 – Reconstruction Plates 3.5 with coaxial combi-holes – Other plate sizes than 3.5 mm
Note: Preoperative pre-bending of the reconstruction plates is always required before in-situ plate bending. The in-situ bending instruments are intended for detailed and accurate adaptation of the plates to the local anatomy.
Notes – Do not bend the plate at the level of the holes. – Do not bend the plate multiple times at the same level
to avoid weakening of the plate.

Place the Pubic Symphysis Plate 3.5 over the symphysis joint and make a temporary fixation (e.g. with plate holding for-ceps).
According to preoperative planning and plate selection (locking/non-locking), use B 3.5 mm cortex screws and/or B 3.5 mm locking screws to fix the plate. If compression is needed between the symphysis joint, use the plate with DCU holes.
Insert the first cortex screw in the lateral part of DCU hole (eccentric). Insert the second cortex screw eccentrically into the DCU hole of the contralateral side of the pubic symph-ysis. (1,2)
Alternate tensioning of the screws results in compression of the symphysis.
Refer to the DCP and LC-DCP Systems technique guide (036.001.093) for more detailed steps during screw insertion and plate fixation.
Additional locking screws should be inserted according to the LCP Locking Compression Plate technique guide (036.000.019). (3)

Insert a screw through the 4-hole low profile pelvic recon-struction plate into the body of the ilium, close to the sciatic notch. (1)
To reduce the posterior iliac fragment, insert a temporary screw into the posterior superior iliac spine. (2) Compress the fracture using the bone holding forceps. The forceps is therefore hooked into the most posterior plate hole and the temporary screw on the other side of the fracture line is used as a counter bearing. (3)
After additional screw fixation through the plate, remove the temporary screw. (4)
Notes – During fixation close to the greater sciatic notch, control
drill bit penetration and screw lengths with two-finger palpation to prevent damage to the nerve or vessels.

Pelvic C-ClampThe Pelvic C-Clamp is an emergency stabilization instrument for unstable injuries and fractures of the pelvic ring. Unstable pelvic ring fractures can be associated with massive loss of blood that can cause terminal shock. The Pelvic C-Clamp allows rapid reduction and stabilization of these unstable pelvic ring fractures, thus assisting the surgeon to gain con-trol of the shock reaction. This neither delays nor hinders subsequent diagnosis and therapy.
Note: The Pelvic C-Clamp is not contained in the pelvic sets. See separate Synthes publication “Pelvic C-Clamp”. Refer to technique guide: 036.000.899.
Large External FixatorIndications for stabilizing the anterior pelvic ring with a large external fixator are: Unstable fractures in the anterior pelvic ring, or symphysis fractures with or without participa-tion of the posterior pelvic ring. This type of stabilization is also possible in emergencies such as polytrauma, open wounds and, where appropriate, as an alternative to internal osteosynthesis.
The pelvis can be stabilized with an external fixator both at the iliac crest and the supraacetabular region.
The clamps are magnetic resonance conditional. This allows magnetic resonance examinations of patients who have been stabilized with the external fixator.
Refer to technique guide: 036.000.237.

Spring Plate 3.5The Synthes Spring Plate 3.5 is intended for reduction and fixation of small bone fragments.
In pelvic and acetabular surgery, it is often difficult to reduce and fix small bone fragments with screws because the fragments may break into even smaller pieces. Mainly in the joint areas (acetabulum) it is essential that even small frag-ments are anatomically reduced and help to achieve again a homogenous joint congruency. The 3.5 Spring Plates are in-tended to reduce and stabilize bone fragments that are too small for screws. They can be used individually or in con-junction with a 3.5 mm reconstruction plate.
Refer to technique guide: 036.000.581.
Sacral BarsThe Synthes 6.0 mm Threaded Sacral Bars offer an additional option for stabilization of the posterior pelvic ring. Two threaded bars are therefore drilled through the poste-rior iliac crests and by compression of the nuts, bridging and compression of the posterior pelvic ring is achieved.
Note: Two 6.0 mm Threaded Sacral Bar Kits are necessary to build the construct described in the technique guide (01.100.763 Sacral Bar Set, Bar Length 200 mm, sterile or 01.100.766 Sacral Bar Set, Bar Length 260 mm, sterile). Also, bolt cutters capable of cutting a 6.0 mm bar will be neces-sary to complete the procedure (Rod Cutter 388.720 is avai-lable). Refer to technique guide: 036.000.740.

Trocar for Cannulated Screws 6.5 and 7.3 mmThe trocar for 6.5 mm / 7.3 mm cannulated screws is in-tended to be used as a drill sleeve for a 2.8 mm guide wire and as a reduction tool, especially in minimally invasive procedures.
In addition to the existing guide handle for Kirschner wires B 2.5 (03.306.009) the new trocar features a pointed tip that provides better traction when used on an irregular bony surface.
The length of the standard trocar for cannulated screws is 300 mm and the long trocar for cannulated screws is 350 mm long. (314.052/314.054)
Curved Pelvic Osteotomy ChiselsThe Curved Pelvic Osteotomy Chisels are general surgical instruments, designed specifically for peri-acetabular osteotomies and are available in 15 mm and 20 mm widths with a smooth curve. (03.100.038/03.100.039)
These instruments feature an improved shape (curved in-stead of angled) compared to the existing Pelvic Osteotomy Chisels (399.850 and 399.860).

MRI Information
Torque, Displacement and Image Artifacts according to ASTM F 2213-06, ASTM F 2052-06e1 and ASTM F2119-07Non-clinical testing of worst case scenario in a 3 T MRI system did not reveal any relevant torque or displacement of the construct for an experimentally measured local spatial gradient of the magnetic field of 3.69 T/m. The largest image artifact extended approximately 169 mm from the construct when scanned using the Gradient Echo (GE). Testing was conducted on a 3 T MRI system.
Radio-Frequency-(RF-)induced heating according to ASTM F2182-11aNon-clinical electromagnetic and thermal testing of worst case scenario lead to peak temperature rise of 9.5 °C with an average temperature rise of 6.6 °C (1.5 T) and a peak temperature rise of 5.9 °C (3 T) under MRI Conditions using RF Coils [whole body averaged specific absorption rate (SAR) of 2 W/kg for 6 minutes (1.5 T) and for 15 minutes (3 T)].
Precautions: The above mentioned test relies on non-clini-cal testing. The actual temperature rise in the patient will depend on a variety of factors beyond the SAR and time of RF application. Thus, it is recommended to pay particular attention to the following points: – It is recommended to thoroughly monitor patients under-
going MR scanning for perceived temperature and/or pain sensations.
– Patients with impaired thermo regulation or temperature sensation should be excluded from MR scanning proce-dures.
– Generally it is recommended to use a MR system with low field strength in the presence of conductive implants. The employed specific absorption rate (SAR) should be reduced as far as possible.
– Using the ventilation system may further contribute to reduce temperature increase in the body.
