Intended Use

The Zimmer Natural Nail System is intended for temporary fracture fixation and stabilization of the bone. Indications for use of the Cephalomedullary nails include: Compound and simple shaft fractures Proximal, metaphyseal and distal shaft fractures Segmental fractures Comminuted fractures Fractures involving osteopenic and osteoporotic bone Pathological fractures Fractures with bone loss Pseudoarthrosis, non-union, mal-union and delayed union Periprosthetic fractures Surgically created defects such as osteotomies Intertrochanteric and subtrochanteric fractures

Device Story

Zimmer Natural Nail System Cephalomedullary Femoral Nail - Asia Short is a temporary intramedullary fixation device for femoral fractures. Device consists of a titanium alloy (Ti-6Al-4V) nail, secured by proximal and distal locking screws; optional nail caps prevent tissue ingrowth. Used by orthopedic surgeons in clinical/surgical settings for fracture stabilization. Modifications from predicate include 9.3 mm diameter line extension, distal locking hole relocation (20 mm distally), reduced tip slot/flute length, and adjusted distal locking hole angle (7.0 degrees) to accommodate targeting guide. Device provides mechanical support to bone segments to facilitate healing.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical bench testing, including fatigue strength evaluation of the proximal segment and distal tip tensile stress evaluation under cantilever loading.

Technological Characteristics

Material: Ti-6Al-4V alloy. Form factor: Intramedullary nail with proximal/distal locking holes and optional caps. Energy source: None (mechanical). Sterilization: Provided sterile. Connectivity: None. Software: None.

Indications for Use

Indicated for patients requiring temporary fracture fixation and stabilization of the femur, including compound, simple, proximal, metaphyseal, distal, segmental, comminuted, pathological, and periprosthetic fractures; fractures with bone loss; osteopenic/osteoporotic bone; pseudoarthrosis; non-union; mal-union; delayed union; and surgically created defects (osteotomies).

Regulatory Classification

Identification

An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.

Zimmer Natural Nail System Cephalomedullary Femoral Nail - Asia Short

Intramedullary Fixation Rod

Intramedullary Fixation Rod , product code HSB (21 CFR section 888.3020)

Zimmer Natural Nail System Cephalomedullary Femoral Nails, Manufactured by Zimmer, K091566, cleared October 28, 2009 and Intramedullary Nail System, Manufactured by Zimmer, K965098, cleared February 28, 1997.

The Zimmer Natural Nail System Cephalomedullary Femoral Nail - Asia Short are temporary fixation intramedullary nails designed for fracture fixation and stabilization of the femur. The nails are available in a variety of lengths and diameters to meet assorted anatomical needs. Each of the intramedullary nails is secured by a series of screws that pass through holes manufactured into the proximal and distal sections of each nail. Nail caps are available to prevent tissue ingrowth into nail threads and increase the length of the nail if desired. These devices are made from Ti-6Al-4V alloy and are provided sterile.

The Zimmer Natural Nail System is intended for temporary fracture fixation and stabilization of the bone.

K120 715 PAGE 2 OF 2 Indications for use of the Cephalomedullary nails include: Compound and simple shaft fractures ● Proximal, metaphyseal and distal shaft fractures ● . Segmental fractures Comminuted fractures . . Fractures involving osteopenic and osteoporotic bone . Pathological fractures Fractures with bone loss . Pseudoarthrosis, non-union, mal-union and delayed . union . Periprosthetic fractures Surgically created defects such as osteotomies . Intertrochanteric and subtrochanteric fractures Comparison to Predicate Device: The subject Zimmer Natural Nail System Cephalomedullary Femoral Nail - Asia Short have three modifications when compared to the predicate Zimmer Natural Nail System Cephalomedullary Femoral Nails; 1) A 9.3 mm diameter line extension was added to the nail scope, 2) the tip design of the subject nails was changed by moving the distal locking holes 20 mm distally and reducing the length of the tip slots/flutes, and 3) the distal locking hole angle was changed from 8.5 degrees to 7.0 degrees to accommodate a minor change in the associated targeting guide instrument. All other design and processing parameters (e.g., other dimensions, materials, sterilization, packaging, etc.) are identical to the predicate devices. Performance Data (Nonclinical Non-Clinical Performance and Conclusions: And/or Clinical): Testing/Analysis performed included; A fatigue strength evaluation of the proximal segment of the subject nail and a distal tip evaluation of the tensile stress under cantilever loading to confirm that the modifications would not affect safety and effectiveness. The results of non-clinical (lab) performance testing demonstrate that the subject devices are safe and effective and substantially equivalent to the predicate devices. Clinical Performance and Conclusions: Clinical data and conclusions were not needed for this device.
