2.0 mm LCP® Distal Ulna Plate. For capital and subcapital fractures of the ulna. The distal ulna is an essential component of the distal radioulnar joint, which helps provide rotation to the forearm. The distal ulnar surface is also an important platform for stability of the carpus and, beyond it, the hand. Unstable fractures of the distal ulna therefore threaten both movement and stability of the wrist. The size and shape of the distal ulna, combined with the overlying mobile soft tissues, make application of standard implants difficult. The 2.0 mm LCP® Distal Ulna Plate is specifically...

Narrow plate design, low screw -plate profile, rounded edges and polished surface are designed to minimize irritation of overlying soft tissue Pointed hooks grip the styloid process and provide a reference point for plate application Round locking holes in the head accept 2.0 mm locking screws Combi holes accept either 2.0 mm locking or cortex screws and allow locking or compression throughout the length of the plate shaft Angled locking screws securely hold the ulnar head 2.0 mm LCP® Distal Ulna Plate Surgical Technique DePuy Synthes

The 2.0 mm LCP Distal Ulna Plate is indicated for fixation of fractures, osteotomies, nonunions, replantations, and fusions of small bones and small bone fragments, particularly in osteopenic bone. 4 DePuy Synthes 2.0 mm LCP® Distal Ulna Plate Surgical T

Clinical Examples Examples include: – Fractures of the ulnar head where the articular surface is either displaced, rotated, or tilted – Comminuted extra-articular fractures of the ulnar neck threatening stable congruency of the distal radioulnar joint Note: Not all fractures of the distal ulna require internal fixation. Many simple ulnar styloid fractures demand nothing more than symptomatic treatment.

Modular Mini Fragment LCP Instruments and Implants Set Titanium LCP Modular Mini Fragment Instruments and Implants Set 1 Approach The ideal insertion site for this implant is located toward the ulnar styloid and between the flexor carpi ulnaris and extensor carpi ulnaris tendons. Make a longitudinal skin incision over the palpable ulna, taking care to avoid the dorsal sensory branch of the ulnar nerve, which crosses the bone at this level. Once the distal shaft of the ulna is visible, subperiosteal dissection will allow the fracture fragments to be visualized and reduced. Gently retract the...

Reduce Fracture and Position Plate 2 Contour plate (optional) Instrument 329.12 Bending Pliers, for 1.5 mm and 2.0 mm plates If necessary, contour the plate using the flat-nosed pliers. Notes – The plate holes have been designed to accept some degree of deformation. The undercut helps to ensure that the threaded holes will not be distorted with typical contouring. Significant distortion of the threaded holes will reduce locking effectiveness. – If possible, the plate should not be cut since the resulting sharp edges can irritate the overlying soft tissues. Precaution: The plate features...

Reduce Fracture and Position Plate 3. Reduce fracture and position plate continued In simple fractures of the ulnar neck, apply the plate to the subcutaneous border of the distal ulna, securing points of fixation in both the head and the shaft. Note: It may be necessary to temporarily stabilize the fracture with a transtyloid 1.1 mm guide wire. The wire should be inserted between the distal hooks of the temporarily applied plate. Precaution: The head of the distal ulna is often fragile. Caution should be exercised if using pointed reduction forceps, since the force of this instrument may...

Adjust Length and Complete Fixation 5 Adjust length and complete fixation Multiple options for screw insertion in the distal portion of the plate allow a wide range of fracture patterns to be securely stabilized. Option 1 In fractures which require length adjustment, place one or two 2.0 mm locking screws in the ulnar head to securely fix the implant distally. Place a 2.0 mm cortex screw in the oblong hole of the shaft, and obtain the correct length of reduction. Use a combination of cortex and locking screws in the surrounding holes to stabilize the fracture securely, as dictated by bone...

Remove the 1.1 mm wire, which was used for preliminary fixation (see note, Step 3). Overdrill the near fragment with a 1.5 mm drill bit. Insert a 1.5 mm cortex screw in lag mode between the arms of the distal...
