Fractures & Dislocations of the Hand and Upper Extremity

Traumatic upper extremity injuries, specifically **bone fractures** and **joint dislocations**, require immediate, specialized orthopedic evaluation to safeguard long-term manual function. Due to the high density of small bones, delicate ligaments, and sliding tendon groups within the hand, wrist, and elbow, even a seemingly minor structural displacement can significantly compromise grip strength, fine motor coordination, and general flexibility if left misaligned.

At Erlanger Hayes Hand Center, our surgical team focuses exclusively on restoring correct anatomical structural alignment (reduction) and solid joint stability following traumatic impacts, falls, sports collisions, or industrial machinery accidents.

Understanding the Distinction

While both conditions stem from acute physical trauma, their pathomechanics target different skeletal components:

• Fractures (Broken Bones): A fracture occurs when physical force breaks the continuity of a bone matrix. This spans from non-displaced hairline cracks to complex, multi-fragment comminuted fractures or open fractures where bone punctures the skin. Common areas include the phalanges (fingers), metacarpals (hand), scaphoid (wrist), and distal radius.
• Dislocations (Joint Displacements): A dislocation describes a complete structural separation where bones forming a joint are forcefully pushed out of their natural alignment. This severe mechanical shifting typically causes extensive stretching or tearing of the surrounding joint capsule and stabilizing collateral ligaments.

Common Symptoms of Skeletal Trauma

Signs of an acute fracture or dislocation in the hand or upper arm usually develop instantly at the moment of impact and include:

• Intense Localized Pain: Severe pain that increases sharply upon trying to move the affected fingers, wrist, or arm.
• Visible Deformity: A crooked appearance, abnormal shortening of a finger, or a prominent, asymmetrical bulge near a joint.
• Rapid Edema & Ecchymosis: Fast swelling and deep bruising due to localized internal bleeding from the ruptured vascular channels within the bone or ligaments.
• Numbness or Paresthesia: A cold, tingling sensation in the fingertips if a displaced bone fragment presses or stretches an adjacent peripheral nerve.

Comprehensive Diagnostic Framework

To establish an exact baseline map of the injury, our clinical team implements immediate imaging assessment. High-resolution digital X-rays are completed from multiple angles to identify the fracture pattern, the degree of fragment displacement, or the exact path of joint shifting. For complex intra-articular injuries—where a fracture line extends directly into a joint surface—a specialized CT scan or high-field MRI may be ordered to fully visualize hidden tissue fragments or associated ligament tears.

Advanced Treatment Protocols

The selection of a treatment path depends on the stability of the injury, the specific bone involved, and whether the joint alignment remains intact.

1. Non-Surgical Realignment and Immobilization

If a fracture is stable and non-displaced, or if a joint dislocation can be cleanly reduced without surgical entry, conservative protocols are highly effective:

• Closed Reduction: The hand surgeon carefully manipulates the displaced bone or joint back into its correct anatomical location under localized or regional block anesthesia.
• Custom Splinting & Casting: Instead of heavy, generic plaster casts, our on-site certified hand therapists fabricate custom, lightweight thermoplastic splints. These protect the healing bone structure while keeping unaffected joints free to move, minimizing overall arm stiffness.
• Monitored Serial X-Rays: Frequent follow-up imaging ensures the bone fragments remain securely in place throughout the critical early weeks of cellular healing.

2. Surgical Fixation and Stabilization

Surgical intervention is required for unstable, displaced, or open fractures, as well as joints that remain unaligned or highly unstable after reduction. Our surgeons utilize advanced outpatient techniques:

• Open Reduction and Internal Fixation (ORIF): The surgeon creates a precise surgical entry to realign the bone pieces exactly. The fragments are then rigidly secured using low-profile titanium plates, microscopic screws, or surgical K-wires. This internal stability allows for early, safe therapeutic movement.
• External Fixation: In severe high-energy crush injuries with compromised soft tissue, an external frame is anchored into healthy bone above and below the trauma site to maintain proper alignment while the skin and muscles heal.
• Ligament Reconstruction: If a dislocation has completely torn crucial stabilizing ligaments (such as the ulnar collateral ligament of the thumb), the tissue is securely anchored back to the bone to prevent chronic joint shifting.
