Finger fractures are common injuries I treat every week in my Dawsonville office — whether from mountain biking in Blue Ridge, hiking near Blairsville, boating on Lake Chatuge in Hiawassee, or work-related injuries in Murphy, North Carolina.
A recent study published in the Journal of Hand Surgery examined an important surgical question:
"Rotational Stability of One Versus Two Intramedullary Screws for Proximal Phalanx Fractures: A Biomechanical Study."
This research helps clarify how we stabilize certain finger fractures — and reinforces an important principle in hand surgery: more hardware is not always better.
Understanding Proximal Phalanx Fractures
The proximal phalanx is the first bone in your finger, just beyond the knuckle. When it breaks, one of the most important concerns is rotational alignment.
A finger can heal slightly rotated and still appear straight when the hand is open. However, when making a fist, even small rotational differences can cause overlap with neighboring fingers, affecting grip, dexterity, and fine motor control.
For active patients throughout Northeast Georgia — from manual laborers to retirees who garden, fish, or golf — restoring precise alignment matters.
What the Study Evaluated
The researchers compared:
- One intramedullary screw placed centrally within the bone
- Two screws placed in a "V" or "lambda" configuration
They created simulated transverse mid-diaphyseal fractures and tested how much rotational force was required to produce 15 degrees of malrotation.
The Key Finding
There was no statistically significant difference in rotational stability between one-screw and two-screw constructs.
In practical terms, when properly sized and positioned, a single intramedullary screw provided similar rotational stability to two screws.
It is important to recognize that this was a biomechanical cadaver study. Real-world surgical planning also considers tendon forces, bone quality, fracture pattern, and the patient’s activity level. Fixation decisions must always be individualized.
Why This Matters for Patients in Northeast Georgia
Many patients understandably assume that more hardware means more strength.
In hand surgery, however, the goal is not to use the most implants — it is to use the most appropriate construct for the specific fracture pattern.
Additional hardware can increase surgical time and bone disruption without necessarily improving stability in certain fracture types. When appropriate, a single well-placed intramedullary screw can provide stable fixation while minimizing additional surgical trauma.
Stable fixation that allows early controlled motion is critical. In my experience, stiffness — not failure of bone healing — is often the most common long-term challenge after proximal phalanx fractures.
How I Apply This in My Practice
In my Dawsonville office, I treat a high volume of finger and hand fractures from across North Georgia and Western North Carolina.
For appropriate transverse mid-shaft proximal phalanx fractures:
- Careful reduction and restoration of rotational alignment are the priority
- Implant choice is tailored to the fracture pattern and bone anatomy
- Early supervised motion is emphasized to protect long-term function
Surgery on the hand is not just about achieving union. It is about preserving tendon glide, joint motion, strength, and fine motor control.
I routinely coordinate care and often collaborate with the excellent physicians from these Northeast Georgia communities to ensure patients receive timely, appropriate, and specialized treatment when needed.
When Is Surgery Necessary?
Not all proximal phalanx fractures require surgery.
Treatment decisions depend on:
- Degree of displacement
- Rotational alignment
- Stability
- Occupational and activity demands
- Overall health and bone quality
Many fractures can be managed non-operatively. Others benefit from surgical fixation to maintain alignment and allow earlier motion.
Individualized evaluation by a fellowship-trained hand surgeon helps determine the best course of action.
Specialized Hand Care in Dawsonville
Many patients from Blairsville, Blue Ridge, Hiawassee, Murphy, and surrounding Northeast Georgia communities choose to travel to Dawsonville for dedicated hand and upper extremity care.
My practice focuses exclusively on conditions of the hand, wrist, and elbow, providing both surgical and non-surgical management tailored to each patient’s functional goals.
If you sustain a finger fracture and would like a subspecialty evaluation focused specifically on hand injuries, my Dawsonville office provides comprehensive care for patients throughout North Georgia and Western North Carolina.
