CZMEDITECH Femoral Intramedullary Nail

Introduction

CZMEDITECH Multi-Loc Humeral Nails provide a comprehensive system for the treatment of humeral fractures. The system consists of short and long nails with multiple screw options to address simple and complex fractures of the proximal humerus as well as humeral shaft.

Innovative design

The system includes several innovative features designed specifically for the clinical needs of

humeral nailing

1. Straight nail with central insertion point

2. Unique screw-in-screw option, for improved stability where needed*

3. Polyethylene inlay for secure screw fixation of proximal screws

4. Ascending screw option to provide support to the calcar

5. Multiplanar distal locking for less implant toggling

6. Fully targeted distal locking for the short nail

Comprehensive options

Short Nail: Right and left nails in 8.5 mm diameters, 160 mm length

Long Nail: Right and left nails in 7.0 mm and 8.0 mm diameters, 200 mm – 300 mm length

Straight Nail With Central Insertion Point

– Designed to avoid potential insertion through the fracture site, increasing biomechanical stability

– Designed to avoid the sulcus between greater tuberosity and humeral head where the supraspinatus tendon inserts

Multi-Loc Screws

– Unique screw-in-screw option, for improved stability where needed*

– Blunt screw tips to reduce risks associated with secondary screw perforation

– Four suture holes per screw, for attachment of rotator cuff tendons

Proximal Fixation

– The ascending calcar screw and the 3.5 mm screw-in-screw options designed to increase resistance to head migration, varus deformation and greater tuberosity rotation

Bicortical Compression: Long Nail

– Designed to increase fracture stability in transverse and short oblique fractures

Distal Locking: Long Nail

– Designed to be in the safe zone between the median and the radial nerve

– Two distal locking options in the anatomic AP direction, designed to facilitate free hand locking

Indications

1. The CZMEDITECH Humeral Nail is intended to provide temporary stabilization of various types of fractures,malunions and nonunions of the humerus.

2. The nails are inserted using an opened or closed technique and can be static, dynamic and compression locked.

3. Types of fractures include, but not limited to fractures of the humeral shaft, non-unions, malalignments,pathological humeral fractures, and impending pathological fractures

Multi-Loc Humeral Nails Contraindications

Physician education, training and professional judgement must be relied upon to choose the most appropriate device and treatment.

Conditions presenting an increased risk of failure include:

1. Any active or suspected latent infection or significant local inflammation in or near the affected area.

2. Damaged blood vessels can inhibit adequate blood supply to the fracture or surgical site.

3. Bone mass damaged by disease, infection, or prior implantation that does not provide adequate support and/or fixation for the device.

4. Obesity. Overweight or obese patients can place loads on the implants that can cause device fixation failure or

5. Failure of the device itself.

6. Patients with insufficient tissue coverage at the surgical site.

7. Use of implants that would interfere with anatomy or physiology.

8. Any psychiatric or neuromuscular disease that creates an unacceptable risk of fixation failure or complications in postoperative care.

9. Other medical or surgical conditions that would preclude the potential benefit of surgery.
