Stiff, aching, swollen finger joints that limit grip, pinch, and daily function — most patients manage finger arthritis well with periodic injections over the long term. When injections no longer hold, Dr. R. David Graham at Jacksonville Orthopaedic Institute offers a precise surgical plan matched to each joint level and each patient's activity demands.
Most patients manage finger arthritis with injections for years. Surgery becomes the conversation when injections no longer provide adequate relief — and which surgery depends entirely on which joint is affected.
Understanding Finger Arthritis
Finger arthritis is not one condition — it's three, each affecting a joint with different biomechanical demands, different functional consequences, and a different surgical solution when the time comes.
The DIP joint is the last joint of each finger — the one closest to the fingertip. Osteoarthritis here is among the most common joint conditions in the hand, particularly in women over 50. Classic findings include Heberden's nodes — bony enlargements on either side of the DIP joint — and sometimes mucous cysts on the dorsal joint surface, which can intermittently drain or cause nail deformity.
The DIP joint has limited arc of motion to begin with, and losing some of that motion to arthritis is tolerated remarkably well by most patients. Pain and swelling during flares are the primary complaints. When injections no longer manage symptoms, fusion (arthrodesis) is the surgical treatment — reliable, durable, and associated with minimal functional loss.
The PIP joint is the middle joint of each finger — the one that bends when you make a fist. Arthritis here is more functionally significant than DIP disease because the PIP joint contributes substantially to grip and fine motor function. Classic findings include Bouchard's nodes, joint line tenderness, and progressive stiffness. PIP arthritis can also result from prior fractures or joint injuries.
When surgery is needed, the choice between fusion and Silastic arthroplasty depends on two factors: the patient's activity level and which finger is involved. High-demand patients and the index and long fingers favor fusion for stability; lower-demand patients and the ring and small fingers — where grip-closing flexion matters more — favor Silastic arthroplasty to preserve motion.
The MCP joint is the large knuckle at the base of each finger — the joint that controls the arc from fully open to fist. Isolated MCP osteoarthritis is less common than DIP or PIP disease, but when it occurs — or when inflammatory arthritis has destroyed the MCP joints — it can severely compromise grip strength and hand function. The index MCP is particularly critical for lateral pinch.
The surgical decision here is primarily driven by which finger is involved. The index finger — subject to significant lateral pinch forces — is more reliably treated with fusion when surgery is needed. The ring, long, and small fingers, where motion matters more than lateral stability, are better served by pyrocarbon arthroplasty — a durable implant material well-suited to the biomechanics of the MCP joint.
Reading the Diagram
Three joints are affected by finger arthritis — the MCP (knuckle), PIP (middle), and DIP (fingertip). Each is shown here with its typical surgical solution below it when injections no longer manage symptoms.
The surgical choice at the PIP and MCP joints is not one-size-fits-all — it depends on which finger and the patient's activity demands. That decision framework is explained in the surgical section below.
Recognizing Finger Arthritis
Finger arthritis presents differently depending on which joint is involved and whether the disease is active or quiescent — but the core pattern of pain, stiffness, and swelling is consistent across joint levels.
Aching or sharp pain directly at the affected joint, provoked by use and eased with rest. Active flares produce tenderness to direct palpation over the joint line. Morning stiffness lasting 30 minutes or less is typical of osteoarthritis — prolonged morning stiffness suggests inflammatory arthritis and warrants rheumatology evaluation.
Active flares produce soft, boggy swelling around the joint. Over time, repeated inflammation leads to bony remodeling — producing the characteristic Heberden's nodes (DIP) and Bouchard's nodes (PIP) that are palpable and sometimes visible as hard knobs on either side of the joint. These nodes are not reversible but are not in themselves dangerous.
Progressive stiffness at the affected joint — initially worse in the morning and after periods of inactivity, eventually more constant. Loss of full flexion impairs grip; loss of full extension impairs reaching. At the PIP joint, flexion contractures are common — the finger adopts a slightly bent resting posture that cannot be fully straightened.
Pain and stiffness translate into functional weakness — difficulty opening jars, gripping tools, turning keys, and performing fine motor tasks. MCP arthritis has the greatest impact on grip strength; DIP arthritis affects precision pinch. Many patients report "dropping things" or avoiding tasks they used to manage easily.
Advanced arthritis can produce joint deformity — lateral deviation, flexion contracture, or hyperextension at adjacent joints as the hand compensates. Deformity at the DIP joint may cause nail changes; at the MCP joint it may ulnar-deviate the finger. Deformity that is painful and limits function is one of the clearer indications for surgical intervention.
DIP joint arthritis is closely associated with mucous cysts — small, fluid-filled ganglion-like cysts that arise from the dorsal DIP joint and may cause nail ridging or intermittently drain. These are not dangerous but can be bothersome. Mucous cyst excision is a separate procedure covered on its own page — the link is in the Related Conditions section below.
Non-Surgical Management
Most patients with finger arthritis manage their symptoms with periodic injections for years. The goal is not to cure arthritis — it can't be cured — but to keep pain at a functional level so that daily activities remain possible without surgery.
A targeted cortisone injection directly into the affected finger joint significantly reduces inflammation, swelling, and pain during flares. The injection is placed with precision into the joint space — DIP, PIP, or MCP as needed — typically with a small amount of local anesthetic for immediate comfort.
In Dr. Graham's experience, cortisone injections for finger arthritis can be administered as frequently as every three months when symptoms require it. Many patients establish a rhythm — coming in for an injection when a joint flares, achieving relief for months, and returning when the next flare occurs. This intermittent management approach allows effective long-term symptom control without surgery.
For patients who prefer a biologically targeted approach — or who want an alternative to repeated cortisone — Platelet-Rich Plasma (PRP) is available for finger joint arthritis. PRP delivers concentrated growth factors directly into the joint, targeting the inflammatory and degenerative processes rather than simply suppressing them.
PRP is a reasonable option for early-to-moderate arthritis where some cartilage remains and biological augmentation may be meaningful. It is also appropriate for patients who have responded well to cortisone but prefer to reduce the frequency of steroid exposure. PRP is cash-pay and not covered by insurance. Dr. Graham is glad to discuss candidacy at your appointment.
Regenerative Treatment
Finger joint arthritis is driven by the progressive loss of articular cartilage and the inflammatory response that accelerates it. Standard cortisone injections are effective at suppressing the inflammatory component but don't address the underlying biology of cartilage breakdown. PRP delivers a different signal — concentrated platelets and growth factors that target both the inflammatory cascade and the biological environment of the arthritic joint.
The evidence for PRP in early-to-moderate osteoarthritis is strongest when meaningful cartilage surface remains — making it most relevant before end-stage disease has fully destroyed the joint. For patients managing finger arthritis with periodic injections who want to explore a more regenerative approach, PRP represents a meaningful addition to the management toolkit rather than a replacement for established cortisone.
In Dr. Graham's experience, PRP is a reasonable discussion for any finger arthritis patient who is actively managing the condition with injections and wants to understand their full range of options. The conversation about PRP candidacy takes place at your appointment, where joint severity and cartilage status can be assessed alongside your goals and preferences.
Surgical Treatment
There is no single surgical solution for finger arthritis. The procedure is matched to the joint, the finger, and the patient's functional demands — and getting that match right is what determines whether surgery actually improves quality of life.
The DIP joint is the smallest and least motion-dependent finger joint. When cortisone injections no longer manage pain adequately, fusion is the definitive treatment. The two bones of the DIP joint are joined together — permanently — eliminating the arthritic joint and the pain it generates. In exchange, the fingertip becomes fixed in a slightly flexed functional position and loses the small amount of motion the DIP joint normally provides. In Dr. Graham's experience, patients almost universally adapt to this without functional difficulty and are relieved of pain.
The arthritic cartilage surfaces are removed and the two bones are positioned in slight flexion and held with internal fixation — typically a headless compression screw, a tension band wire construct, or a combination, depending on bone quality and anatomy. The bones heal together over 6 to 10 weeks. Once healed, the fusion is permanent and pain-free.
The DIP joint normally contributes only a modest arc of motion — and because the PIP joint remains fully mobile, grip, pinch, and most fine motor tasks are preserved. Most patients are surprised by how little functional loss they notice after DIP fusion once they have healed.
→ DIP fusion is used for all patients with DIP joint arthritis when surgery is indicated — it is the only surgical option at this joint level and produces reliable, durable results.
The PIP joint is the most functionally significant finger joint — it contributes the majority of the flexion arc that makes grip possible. When surgery is needed, Dr. Graham chooses between arthrodesis (fusion) and Silastic arthroplasty based on two factors working together: the patient's activity level and which finger is involved. Neither alone is sufficient — the combination determines the right approach.
For active, high-demand patients — and for arthritis affecting the index or long finger — fusion is the more reliable choice. The PIP joint is fused in a functional position (typically 30–40° of flexion), eliminating the arthritic pain permanently and providing a stable, strong platform for pinch and grip.
The index finger in particular experiences significant lateral forces during pinch — a Silastic implant in this position is at higher risk of implant deformity over time. Fusion in the index finger provides stability without that concern.
→ High activity demands + index or long finger = fusion is the preferred choice.
For lower-demand patients — and for arthritis in the ring or small finger where grip-closing flexion matters more than stability — Silastic arthroplasty preserves motion at the PIP joint. A flexible silicone implant replaces the arthritic joint surfaces, allowing pain-free flexion and extension within a reduced but functional arc.
Silastic implants are a well-established option with decades of clinical history. They are not indefinitely durable — the implant may fracture over time, particularly under heavy repetitive loading — but for the appropriate patient in the appropriate finger, they provide meaningful long-term benefit.
→ Lower activity demands + ring or small finger = Silastic arthroplasty is the preferred choice.
MCP joint arthritis surgery is primarily driven by which finger is affected. The index finger — which bears significant lateral pinch forces — is more reliably treated with fusion when surgery is indicated. The ring, long, and small fingers — where motion through a functional arc contributes more to grip than lateral stability — are better served by pyrocarbon arthroplasty, a modern implant material that offers superior durability compared to Silastic at this joint level.
The index finger MCP joint is the fulcrum of lateral pinch — pinching against the thumb. This applies significant lateral stress to the MCP joint that an arthroplasty implant handles less reliably than the ring or small finger. Fusion of the index MCP joint provides a stable, strong, permanently pain-free knuckle that withstands pinch demands.
The MCP joint is fused in approximately 15–25° of flexion, providing a functional position for pinch while preserving the finger's ability to grasp objects of varying sizes through the other joints.
→ Index finger MCP arthritis = fusion is the preferred surgical treatment.
For the ring, long, and small finger MCP joints — where motion is critical for grip and lateral pinch demands are lower — pyrocarbon arthroplasty is Dr. Graham's preferred surgical option. Pyrocarbon is a synthetic carbon material with mechanical properties that closely mimic articular cartilage, making it well-suited to the biomechanics of the MCP joint.
Pyrocarbon implants offer greater durability than Silastic, a more anatomical design, and better compatibility with the normal joint kinematics of the MCP. Recovery involves a period of protected motion followed by progressive strengthening through formal hand therapy.
→ Ring, long, or small finger MCP arthritis = pyrocarbon arthroplasty is the preferred surgical treatment.
Recovery
Recovery varies by procedure. All finger arthritis surgeries are outpatient — patients go home the same day — but healing timelines and therapy requirements differ.
Finger splint protecting the fused joint while bone consolidation occurs. Adjacent joints are kept mobile to prevent stiffness. No active motion at the fused joint — bone must heal before any loading is applied.
X-rays confirm bone healing across the fusion site. Once solid healing is confirmed, the splint is discontinued. Progressive loading and return to functional activities begins. Formal therapy begins if motion at adjacent joints requires attention.
In Dr. Graham's experience, most patients reach full functional return by 3 months after finger fusion — pain-free, with full grip and pinch strength through the mobile joints. The fused joint itself requires no ongoing management once healed.
Dynamic splinting begins early to protect the implant while allowing controlled range of motion. Early, guided motion is essential for arthroplasty outcomes — the joint must move to prevent capsular stiffness while the soft tissues heal around the implant.
Progressive strengthening and motion restoration under hand therapist guidance. Range of motion gains made during this phase are critical to the final result — commitment to therapy is the single biggest factor in arthroplasty outcomes.
Most patients reach full functional return by 3 to 4 months after arthroplasty. Motion in the replaced joint is reduced compared to a normal joint but pain-free and functional — a meaningful trade for a patient who was previously limited by pain.
"Dr. Graham explained everything so clearly — the options, the trade-offs, what surgery would and wouldn't do. I finally felt like I understood my own hands and could make a real decision. The results have been outstanding."
