Microlock Locking Hand System

Microlock Locking Hand System by Siora Surgicals Pvt. Ltd. has been designed to address fractures of small bones in the hand including carpals, metacarpals, and phalanges. They have an anatomically contoured structure that allows for optimal placement and proper fracture healing. Additionally, their low-profile design minimizes soft-tissue irritation and damage to the blood supply.

What is a Hand Locking System?

A hand locking system refers to an advanced orthopedic fixation technique used to stabilize fractures in the hand, wrist, and forearm. It consists of specially designed hand bone plates and screws that lock together, providing enhanced stability and support during the healing process. Unlike conventional fixation methods, where screws compress the plate onto the bone, the locking system allows screws to lock directly into the plate, creating a more rigid construct. This mechanism reduces the risk of implant failure, promotes better bone healing, and minimizes the need for extensive soft tissue dissection. Locking hand plates are commonly used in cases of complex fractures, osteoporosis, and revision surgeries where traditional fixation may not provide adequate stability.

How Long Does a Fractured Hand Take to Heal?

The healing time for a fractured hand typically ranges between 4 to 8 weeks, depending on factors such as fracture severity, age, overall health, and treatment method. Simple fractures may heal within a month with proper immobilization using a cast or splint, while complex fractures requiring surgery or external fixation may take longer. After the initial healing phase, physical therapy is often recommended to restore strength, mobility, and functionality. In some cases, complete recovery, including regaining full movement and strength, may take 3 to 6 months. Delayed healing can occur due to poor blood circulation, smoking, diabetes, or inadequate nutrition. A doctor will monitor healing progress through X-rays and adjust treatment accordingly.

Advantages of a Locking Hand System

A locking hand system offers several advantages over traditional bone fixation methods:

Better Stability

The screws lock into the plate for hand fracture, creating a strong, fixed-angle construct that provides superior stability, even in osteoporotic or weakened bones.

Reduced Risk of Implant Failure

Since the screws do not rely on friction alone, there is a lower risk of loosening, making the system more reliable.

Minimized Bone Damage

Traditional fixation methods may compress the locking hand plate onto the bone, disrupting the blood supply. The locking system preserves vascularity, promoting better healing.

Lower Soft Tissue Damage

Requires minimal soft tissue dissection, reducing complications such as infections and delayed healing.

Early Mobilization

Due to its strong fixation, patients may start gentle movements sooner, reducing stiffness and improving recovery outcomes.

Overall, the locking hand system is a preferred choice for complex fractures, allowing for more predictable and successful bone healing.

Uses of Microlock Locking Hand System

Microlock Locking Hand Plates are used for the fixation of fractures without deformation. It can be used in Bridge Mode across the bone loss. It has the versatility to achieve compression at the fracture site. Metacarpal Periarticular Fracture Plates and Phalangeal Periarticular Fracture Plates are appropriate for addressing intra-articular and extra-articular fractures of the hand.

Is VA (Variable Angle) Hand System the Same as the Locking Hand System?

The VA (Variable Angle) hand system is a specialized type of locking hand system but with added flexibility. While both systems use locking plates and screws, the VA system allows screws to be inserted at different angles rather than a fixed trajectory. This variable-angle feature provides surgeons with more versatility in fracture fixation, especially in cases with small or fragmented bones where precise screw placement is crucial. Let us have a detailed comparison between the two:

Feature Variable Angle Hand System Locking Hand System
Definition A specialized type of locking system that allows screws to be inserted at different angles. A bone fixation system where screws lock into the plate at fixed angles for stability.
Screw Angles Variable angles (typically 15-30°) for flexible placement. Fixed angles are determined by the plate design.
Customization Greater flexibility in screw positioning for irregular fractures. Limited to predefined screw trajectories.
Bone Contact Allows precise adaptation to bone structure, improving fixation in small or complex fractures. Less adaptable to unique bone shapes due to fixed-angle constraints.
Stability Provides strong fixation with enhanced adaptability. Offers high stability but lacks angle flexibility.
Ideal Uses Complex or multi-fragment fractures that require customized screw positioning. Standard fracture fixation with predictable bone alignment.
Surgical Precision Increased due to adjustable screw placement. More straightforward but may be restrictive in certain cases.
Benefits in Healing Improves fracture fixation in challenging anatomical locations. Provides reliable healing but may not be ideal for highly fragmented fractures.
