Total Hip Prosthesis Instruments Set – Cementless THA Acetabular & Femoral Instrumentation

The Total Hip Prosthesis Instruments Set from Peak Surgicals is a complete orthopedic instrument set in surgical-grade stainless steel, designed to support the full intraoperative workflow of total hip arthroplasty — with particular depth in acetabular preparation, cementless cup placement with screw fixation, and femoral head trialling for both 22mm and 28mm head diameters. The set is supplied with a dedicated empty container and is used by orthopedic surgeons in hospital operating theatres and surgical centers performing primary and revision total hip replacement procedures worldwide.

Acetabular Preparation: Reamers, Drill, and Flexible Drill

Precise acetabular preparation is the foundation of reliable cementless cup fixation in total hip arthroplasty. The set includes Acetabular Reamers in sizes O42mm through O60mm (PS-9713-0042 to PS-9713-0060) for progressive hemispherical reaming of the acetabular cavity to the planned cup size, ensuring the final reamed surface closely matches the outer geometry of the cementless cup to maximize primary press-fit stability. The Acetabular Reamer Holder (PS-9713-0002) provides the rigid, controlled attachment between the reamer and the driving handle needed for accurate cavity preparation without reamer wobble. For acetabular cup fixation using supplementary screws — the standard approach in cementless total hip arthroplasty with cups that have screw holes — the Acetabular Screw Head Drill (PS-9713-0009) prepares the screw trajectories through the cup into the ilium, ischium, or pubis. The Flexible Drill (PS-9713-0010) extends drilling access to trajectories that a standard rigid drill cannot reach within the constraints of the surgical exposure.

Acetabular Cup Trialling, Placement, and Angular Alignment

The set includes Acetabular Cup Trials in sizes O42mm through O60mm (PS-9713-1042 to PS-9713-1060) corresponding to the reamer size range, allowing the surgeon to confirm cup size, depth of seating, and soft tissue tension before the definitive implant is introduced. The Acetabular Cup Holder (PS-9713-0015) provides firm grip and orientation control during cup introduction and impaction. Cup Impactor components (PS-9713-0005 through PS-9713-0007) cover both O22mm and O28mm head size configurations, ensuring the cup is seated to the correct depth and orientation at final impaction. The Acetabular Angle Device (PS-9713-0014) assists in confirming and maintaining the correct anteversion and abduction angle of the acetabular cup throughout placement — cup malposition is a primary contributor to instability, edge loading, and accelerated bearing wear in total hip arthroplasty, making angle verification a critical intraoperative step. The Acetabular Cup/Liner Impactor (PS-9713-0017) seats the polyethylene or ceramic liner into the metal shell after cup fixation.

Femoral Head Trialling and Ancillary Instruments

The femoral head component of the set includes Head Trials from O22+0 (M) through O28+8 (XXL) (PS-9713-2200 to PS-9713-2808), covering the 22mm and 28mm head diameter ranges with multiple neck length offsets per diameter to allow precise leg length and offset restoration during trialling before final head assembly. The Mandrel Handle (PS-9713-0003) provides controlled leverage for femoral component positioning and trial manipulation. The Acetabular Screw Forceps (PS-9713-0013) allow secure manipulation, introduction, and alignment of acetabular fixation screws through the cup holes and into the prepared drill trajectories in the pelvic bone. The Screwdriver (PS-9713-0018) seats and tightens the fixation screws to the required torque. The Drill Guide/Acetabular Liner Extractor (PS-9713-0011) guides the drill accurately through cup screw holes and doubles as an acetabular liner extraction tool for revision procedures. The Connection Part (PS-9713-0004) interfaces components within the set for a continuous surgical workflow.

Stainless Steel Construction and Container

Each instrument in the set is manufactured from surgical-grade stainless steel, providing the structural rigidity required for repeated impaction, driven reaming, and drill use across multiple surgical procedures without deformation or dimensional change. The set is supplied in the dedicated Empty Container (PS-9713-000), which organizes all instruments in a defined layout for sterilization processing, theatre transport, and instrument count management between cases. Stainless steel construction ensures all instruments are compatible with standard autoclave sterilization protocols used in licensed hospital operating theatre environments.

Frequently Asked Questions

What is total hip arthroplasty and what role does this instrument set play?
Total hip arthroplasty (THA) is the surgical replacement of the hip joint with a prosthesis consisting of a femoral stem, femoral head, acetabular cup, and bearing liner. It is performed primarily for end-stage hip osteoarthritis, avascular necrosis of the femoral head, inflammatory arthritis, and post-traumatic arthritis where the articular surfaces of both the femoral head and acetabulum are destroyed. The Total Hip Prosthesis Instruments Set provides the dedicated instrument tray required to carry out every intraoperative step of THA: preparing the acetabular cavity to receive the cup, trialling the cup size, placing and impacting the definitive cup, fixing it with supplementary screws, seating the liner, trialling the femoral head size and offset, and assembling the final head. Without a complete, correctly sized instrument set, the precision of cup positioning, leg length restoration, and bearing assembly that determines the long-term success of THA cannot be achieved.

What makes this set acetabulum-focused compared to other hip sets?
The Total Hip Prosthesis Instruments Set has a notably deeper acetabular instrument inventory than the other hip arthroplasty sets in the Peak Surgicals range. It includes a complete reamer series from O42mm to O60mm, a matching cup trial series in the same size range, the Acetabular Angle Device for intraoperative cup orientation verification, the Acetabular Screw Head Drill and Flexible Drill for screw trajectory preparation, Screw Forceps for screw handling, a Screwdriver for fixation screw tightening, and the Cup/Liner Impactor for liner seating — reflecting the full instrument demand of cementless acetabular cup fixation with supplementary screw fixation. This configuration is suited to primary THA procedures using press-fit cementless cups, where the quality of acetabular preparation and cup orientation are the primary determinants of long-term implant survival.

What femoral head sizes does this set support?
The set supports both 22mm and 28mm femoral head diameters. The Head Trial range covers O22+0 (M) through O28+8 (XXL), providing multiple neck length offsets within each head diameter to allow precise intraoperative leg length and hip offset restoration before the final head is assembled on the femoral taper. The Cup Impactor components are provided in both O22mm and O28mm configurations, confirming the set is equipped for both head diameter options at final implant assembly. For centres using larger head diameters (32mm, 36mm) in total hip arthroplasty, confirm the set's compatibility with your implant system before ordering.

Is this set suitable for revision total hip arthroplasty?
The set includes instruments applicable to revision THA cases: the Drill Guide/Acetabular Liner Extractor (PS-9713-0011) provides a liner extraction function for cases where the acetabular liner requires exchange without cup revision, and the cup trial and reamer series cover a wide size range that accommodates the larger acetabular cups frequently used in revision THA where the native acetabular bone has been reamed to a larger diameter in a prior procedure. For revision cases involving significant acetabular bone loss or requiring jumbo cups above O60mm, or cases requiring constrained liners or dual-mobility cups not accommodated by this instrument set, confirm the set's compatibility with your planned revision implant system before procurement.

What certifications does this set carry?
The Total Hip Prosthesis Instruments Set is manufactured under CE Mark, ISO 13485, and FDA compliant quality standards. ISO 13485 certification confirms Peak Surgicals operates a documented quality management system covering design control, material traceability, and manufacturing consistency for orthopedic surgical instruments. CE Mark confirms conformity with European medical device regulations, and FDA compliance supports procurement for US hospitals, ambulatory surgical centers, and orthopedic departments requiring verified regulatory documentation for capital instrument set purchases.
