Distal Medial Humeral Locking Plate

Anatomically precontoured plates

• Designed to reduce soft tissue irritation due to flat and rounded profiles

• Stable treatment with 2-plate-AO-technique, displaced by 90°

• Screw system with angular stability, 2.7 mm and 3.5 mm, for optimal load transfer

Extensive options for fixation

• 2.7 mm angular stable screws up to 60 mm in length for optimal anchoring in the distal block. Alternatively, 3.5 mm cortex screws can be used.

• Five options for screwing into the distal block permit the fixation of extremely distal fractures, especially in osteoporotic bone

• Three additional screws for the fixation of the capitellum

Distal Medial Humeral Locking Plate: An Overview

Fractures of the distal medial humerus are common and often difficult to treat. The distal medial humeral locking plate (DMHLP) has emerged as a popular surgical option for treating these fractures. In this article, we will provide an overview of DMHLP, including its design, surgical technique, indications, outcomes, and potential complications.

Anatomy and Fracture Patterns

Before discussing DMHLP, it is important to understand the anatomy and fracture patterns of the distal medial humerus. The distal medial humerus is the part of the humerus bone that is closest to the body. Fractures in this area often involve the articular surface, which is the part of the bone that forms a joint with the ulna bone in the forearm. These fractures can be complex and may involve the olecranon fossa, coronoid process, and medial epicondyle.

Design and Composition of DMHLP

DMHLP is a type of orthopedic implant designed to stabilize fractures of the distal medial humerus. The plate is made of titanium or stainless steel and has a low-profile design to minimize soft tissue irritation. It contains multiple screw holes that allow for secure fixation of the plate to the bone. The locking screws used in DMHLP create a fixed-angle construct that provides increased stability compared to conventional plates.

Surgical Technique

Surgical fixation of distal medial humerus fractures using DMHLP is typically performed under general anesthesia. The surgeon makes an incision on the medial aspect of the elbow to expose the fracture site. After reducing the fracture, the DMHLP is contoured to fit the bone and then fixed in place using locking screws. The plate is typically placed on the medial aspect of the bone to provide maximum stability.

Indications for DMHLP

DMHLP is indicated for the treatment of complex fractures of the distal medial humerus. This includes fractures that involve the articular surface of the bone, as well as fractures that extend into the olecranon fossa, coronoid process, or medial epicondyle. DMHLP may also be used in cases where there is a risk of postoperative instability, such as in patients with osteoporosis.

Outcomes and Complications

Studies have shown that DMHLP provides excellent outcomes for patients with distal medial humerus fractures. The use of DMHLP has been associated with high rates of fracture union, good functional outcomes, and low rates of implant-related complications such as screw loosening and plate breakage. However, as with any surgical procedure, there is a risk of complications, including infection, nerve injury, and implant failure.

Conclusion

Distal medial humeral locking plate is a highly effective surgical option for treating complex fractures of the distal medial humerus. Its unique design and fixation method provide increased stability and excellent outcomes for patients. However, as with any surgical procedure, it is important to carefully consider the indications, potential risks, and benefits of DMHLP before proceeding with surgery.
