Educational Abstract: Ultrasound-Guided Needle Fenestration for Tendinopathy with Integrative Chiropractic and Functional Medicine Care

In this educational post, I, Dr. Alexander Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, ATN, CCST, present a comprehensive, first-person exploration of ultrasound-guided needle fenestration (also known as tendon fenestration or dry needling of tendons) as a modern, evidence-based intervention for chronic tendinopathy, particularly tennis elbow (extensor carpi radialis brevis, ECRB). I describe the technique, physiological rationale, ultrasound in-plane guidance, dosing (number of passes), and integration with orthobiologics such as dextrose prolotherapy and platelet-rich plasma (PRP). I also explain how we integrate this intervention into a chiropractic and functional medicine model that includes medical oversight, structured rehabilitation, and personal injury care.

I highlight our multidisciplinary framework at Injury Medical Clinic PA (Mission Plaza Injury Medical Clinic) in El Paso, Texas, where Dr. Maria Guadalupe Cardenas, MD (Board Certified in Internal Medicine; NPI #1164426749; Texas MD License #J2933)—with over 40 years of clinical experience—serves as our Medical Director and Collaborative Physician, working closely with me, Dr. Alex Jimenez, DC. In this framework, we deliver patient-centered care that integrates medical diagnostics, interventional procedures, chiropractic neuromusculoskeletal optimization, functional medicine strategies, and graded rehabilitation. We emphasize outcomes tracking, ultrasound-based assessment, informed consent, and safety. The post synthesizes recent literature and leading researcher insights, translating them into practical, patient-focused steps.

Key topics include:

• What needle fenestration is, why we use it, and how it triggers a controlled healing response
• The ultrasound-guided technique: in-plane approach, bevel orientation, redirection strategy, and pass counts
• The biological underpinnings: neovascular modulation, fibroblast activation, mechanotransduction, growth factor signaling, and nociceptive pathway recalibration
• Integrative chiropractic care: spinal and regional joint biomechanics, kinetic-chain optimization, load management, and proprioceptive retraining
• Medical oversight: patient selection, risk mitigation, anesthesia, sterile technique, and post-procedure pharmacologic considerations
• Adjunctive therapies: prolotherapy (dextrose), PRP, shockwave, eccentrics and isometrics, BFR, and tendon-loading progressions
• Clinical pathways for personal injury, workers’ compensation, and return-to-work/return-to-sport
• Data-driven care: PROMs, ultrasound features, re-injury prevention, educational counseling, and psychosocial determinants

The goal is to empower patients and clinicians with a clear, evidence-based roadmap for diagnosing, treating, and rehabilitating tendinopathy using needle fenestration within a safe, integrated, and outcome-focused system of care.

Needle Fenestration for Tendinopathy: A Patient-Centered Journey

I am Dr. Alexander Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, ATN, CCST. In our clinic, we work every day to solve the puzzle of chronic tendon pain through evidence-based, integrative methods. Today, I will guide you through one of the most useful tools in our repertoire: ultrasound-guided needle fenestration, often called “tendon fenestration” or “dry needling of the tendon.” I will also explain how we integrate this interventional procedure with chiropractic care, functional medicine, and rehabilitative science to ensure patients receive complete, thoughtful care.

Before we proceed, I want to acknowledge our collaborative team. Our Medical Director and Collaborative Physician is Dr. Maria Guadalupe Cardenas, MD (Board Certified in Internal Medicine), who brings over 40 years of internal medicine expertise to our practice at Injury Medical Clinic PA (Mission Plaza Injury Medical Clinic) in El Paso, Texas. Her credentials include NPI #1164426749 and Texas MD License #J2933. She works in tandem with me, blending medical oversight, imaging, safety protocols, and pharmacologic guidance with musculoskeletal optimization through chiropractic and functional medicine.

When patients come to us with persistent tendon pain—tennis elbow, patellar tendinopathy, Achilles tendinopathy, rotator cuff tendinosis—we start by asking the right questions, reviewing the history carefully, performing a thorough physical and functional evaluation, and utilizing ultrasound imaging to pinpoint the degenerative areas. If conservative measures have failed or plateaued, needle fenestration can catalyze healing by converting the chronic degenerative state into a controlled acute phase—carefully and precisely—under ultrasound guidance.

Understanding Chronic Tendinopathy: Why Pain Persists

• Key term: chronic tendinopathy
• Key concept: degenerative-reparative mismatch

Chronic tendinopathy is not simply inflammation. In many cases, it is a degenerative process—a failed healing response characterized by disorganized collagen, increased ground substance, and in some cases neovascular ingrowth with accompanying nociceptive fiber ingrowth. Patients often describe pain with loading—gripping, lateral elbow stress, pushing, jumping or running, overhead activities—and the tendon exhibits hypoechoic changes on ultrasound, with loss of the crisp fibrillar pattern and focal thickening.

From a physiological standpoint, chronic tendinopathy can involve:

• Collagen disarray and increased type III collagen replacing stronger type I
• Tenocyte phenotype alteration, including disordered matrix production
• Neovascularization and nerve ingrowth that sensitize the tendon region
• Low-grade metabolic imbalance, where the tendon matrix is undernourished or subjected to loads it cannot adapt to
• Mechanotransduction dysfunction, whereby appropriate loading stimuli fail to trigger robust, organized remodeling

This degenerative milieu has limited capacity to re-enter an acute, organized healing phase without a “reset.” That’s where needle fenestration fits—a targeted, ultrasound-guided intervention designed to induce microtrauma, encourage localized bleeding, and rekindle a healing cascade. We then pair this acute-phase trigger with smart load progressions, chiropractic joint optimization, and metabolic support to guide the tendon back to function.

What Is Needle Fenestration?

• Key term: needle fenestration (tendon fenestration)
• Key distinction: often performed without injectate; can be paired with prolotherapy or PRP

Needle fenestration is the deliberate creation of multiple, controlled micro-perforations within the pathologic region of a tendon using a fine needle under ultrasound guidance. The objective is to convert a chronic lesion into a managed, acute wound by initiating localized bleeding and an inflammatory milieu that can increase growth factor concentration and recruit reparative cells. By doing so, we aim to set the stage for proper collagen alignment through subsequent loading programs and rehabilitative strategies.

While the technique can be performed as a “dry” procedure (no injectate), it is commonly paired with:

• Dextrose prolotherapy (typical concentrations 15–25% for peritendinous, sometimes higher for specific indications): a hyperosmolar solution designed to provoke a mild inflammatory response and promote healing
• Platelet-rich plasma (PRP): a concentration of autologous platelets delivering growth factors like PDGF, TGF-β, VEGF, and IGF-1
• Occasionally, other orthobiologics depending on patient-specific indications and evidence

Our approach is individualized. We choose between a purely fenestrative procedure, dextrose prolotherapy, or PRP based on ultrasound findings, chronicity, patient comorbidities, and prior responses to care. Dr. Cardenas oversees the medical aspects, including screening for contraindications, anticoagulation management, and anesthetic choices, while I focus on ultrasound-guided technique and functional rehabilitation.

Why Needle Fenestration Works: A Scientific Narrative

• Key term: mechanobiology
• Key mechanisms: microtrauma, inflammation cascade, growth factor activation, remodeling

The biological rationale for fenestration is straightforward but powerful:

1. Microtrauma induces controlled bleeding in a chronic, relatively quiescent lesion.
2. Platelet degranulation and local upregulation of growth factors (e.g., PDGF, TGF-β, VEGF) increase tenocyte activity and matrix synthesis.
3. Inflammatory signaling recruits reparative cells and modulates extracellular matrix turnover.
4. Collagen remodeling—especially if guided by proper loading—realigns fibers to functional orientation.
5. Neovascular and nociceptive fiber modulation may downregulate pain signaling over time.

This combination facilitates a rebooting of the healing process. Without appropriate post-procedure care, however, the potential benefits can dissipate. Thus, the intervention is not isolated; it is integrated with load management, eccentric and isometric exercises, chiropractic joint optimization (to normalize regional kinematics), and functional medicine strategies that address recovery capacity (nutrition, sleep, systemic inflammation).

Our Multidisciplinary Model: MD Oversight + Chiropractic + Functional Medicine

• Key roles:

• • Maria Guadalupe Cardenas, MD: Medical Director and Collaborative Physician (Internal Medicine; NPI #1164426749; Texas MD License #J2933)
  • Alex Jimenez, DC, APRN, FNP-BC: Chiropractic care, ultrasound-guided procedures, functional and rehabilitative pathways

Our clinic—Injury Medical Clinic PA, also known as Mission Plaza Injury Medical Clinic—functions as a multidisciplinary integrative system. This is common in injury care and integrative practices, where an MD provides medical direction alongside a chiropractor. Dr. Cardenas’ role is crucial for:

• Medical screening and patient selection
• Informed consent, anesthesia planning (e.g., 1% lidocaine for skin and subcutaneous local anesthesia)
• Review of medications (e.g., anticoagulants, NSAIDs) and comorbidities (e.g., diabetes, autoimmune disease)
• Infection prevention protocols and sterile technique
• Selection of adjunct therapies (e.g., PRP vs. prolotherapy) and post-procedure pharmacology

My role focuses on:

• Ultrasound-guided needle fenestration technique
• Chiropractic evaluation and correction of kinetic-chain dysfunction (cervical-thoracic-shoulder-elbow-wrist-hand alignment, hip-knee-ankle linkages)
• Rehabilitation programming—isometrics, eccentrics, heavy slow resistance, tempo work
• Functional medicine—nutrition, anti-inflammatory strategies, sleep, stress management
• Personal injury cases—documentation, causation analysis, return-to-work/sport plans

This synergy ensures safety, precision, and continuity of care.

Ultrasound-Guided Technique: Precision at Every Step

• Key terms: in-plane approach, long-axis imaging, bevel orientation

In our practice, ultrasound guidance is not optional—it is central. Visualization ensures that the needle path is precise, the lesion coverage is complete, and adjacent structures are respected. Here is how I execute the technique:

1. Patient Positioning

• • For lateral epicondylalgia (tennis elbow), position the patient with the forearm supported and the elbow slightly flexed. We align the extensor tendon origin at the lateral epicondyle for optimal imaging.
  • Place the transducer to visualize the ECRB tendon in long axis, revealing fibrillar alignment and hypoechoic degenerative zones.

• In-Plane Needle Alignment

• • I choose a needle gauge based on the tendon and intended injectate (if used). Commonly, a 22–25 gauge needle is selected for fenestration.
  • I approach in-plane to see the needle throughout its trajectory. This is non-negotiable for safety and precision.
  • The bevel-up orientation provides controlled entry and tactile feedback.

• Anesthesia and Preparation

• • We often anesthetize the superficial tissues with 1% lidocaine using a 27-gauge needle. Dr. Cardenas oversees dosing and contraindications.
  • The field is prepped sterilely; sterile gel and probe covers are used.

• Targeting the Hypoechoic Zone

• • I align the needle along the long axis of the tendon, entering the hypoechoic area that correlates with clinical pain and sonographic pathology.
  • With steady hand-eye coordination, I advance to the lesion, verifying continuous visualization of the needle tip.

• Fenestration Pattern and Pass Counts

• • Once within the lesion, I perform controlled advancement and withdrawal, slightly redirecting to cover the lesion.
  • The number of passes varies by lesion size—typically between 15 and 5.0. This aligns with published ranges and clinical experience.
  • The tendon often feels “softer” as the passes proceed, indicating tissue disruption and microbleeding.

• Transducer Reorientation

• • I may rotate the transducer 90 degrees (short-axis) to assess medial-lateral coverage.
  • Additional passes are directed to ensure we have comprehensively addressed the pathologic zone without over-penetration.

• Adjunct Injection (If Planned)

• • If we have chosen prolotherapy (e.g., 15–25% dextrose for peritendinous support; higher concentrations based on protocol), I inject after fenestration with meticulous visualization.
  • For PRP, we coordinate timing and tendon state to optimize delivery into the fenestrated tissue.

• Post-Procedure Protocols

• • A compressive wrap may be applied.
  • We counsel on relative rest for the initial window, followed by graded loading.

This structured, ultrasound-first approach allows me to ensure accuracy while minimizing risk. Visualization is everything.

Dextrose Prolotherapy: Why and When We Use It

• Key terms: dextrose prolotherapy, hyperosmolar stimulus, proliferant

When I choose to integrate dextrose prolotherapy, it is to amplify the biologic signal toward healing. Dextrose functions as a hyperosmolar agent that can:

• Stimulate local inflammatory mediators within a controlled range
• Support fibroblast proliferation and matrix deposition
• Complement the mechanical stimulus of fenestration

Concentration matters:

• Peritendinous injections may use 15–25%
• Intratendinous strategies and specific protocols may vary; patient selection and safety, overseen by Dr. Cardenas, are central.

In practice, dextrose is a cost-effective option with a favorable safety profile when executed by trained clinicians under sterile technique and ultrasound guidance. In our clinic, we choose dextrose when patients prefer a simpler, lower-cost adjunct to fenestration or when PRP is not indicated or desired.

Platelet-Rich Plasma (PRP): Biologic Synergy

• Key terms: PRP, growth factors, autologous biologic

For select tendinopathies, PRP may complement fenestration by delivering a high concentration of platelets and growth factors directly to the lesion. Depending on the protocol and literature trends:

• Leukocyte-rich PRP may be considered for certain chronic tendinopathies; others may favor leukocyte-poor depending on site and goals.
• PRP is often chosen when patients have recurrent tendinopathy, large hypoechoic areas, or when prior conservative care failed.

The potential advantages include:

• Enhanced growth factor milieu
• Improved tenocyte activity
• Possibly better mid-term outcomes in refractory cases

We counsel patients on evidence variability, cost, and expected timelines. Dr. Cardenas ensures appropriate screening (e.g., platelet disorders) and manages peri-procedural medications. I focus on precise delivery and rehabilitation coordination.

Safety, Contraindications, and Risk Mitigation

• Key terms: sterile technique, anticoagulation management, neurovascular safety

Ultrasound guidance significantly improves the safety profile; however, vigilance is essential. Our safety strategies include:

• Pre-procedure screening: anticoagulants, bleeding disorders, infection risks, uncontrolled diabetes, immune compromise
• Sterile technique: skin prep, sterile probe cover, sterile gel, clean field
• Anesthesia: appropriate dosing of lidocaine; avoid intratendinous anesthetic volume that might affect cellular function
• Needle control: continuous visualization; avoid neurovascular structures
• Post-procedure monitoring: immediate observation, clear instructions, emergency contact

We do not proceed if risk-benefit is unfavorable. With Dr. Cardenas’ oversight, we ensure medical alignment and informed consent.

Understanding Plantar Fasciitis- Video

Integrative Chiropractic Care: Aligning the Kinetic Chain

• Key terms: kinetic-chain optimization, regional interdependence, spinal and peripheral joint biomechanics

Chronic tendon pain frequently reflects regional mechanical issues. For tennis elbow, for instance, the cervical-thoracic-shoulder-elbow-wrist-hand chain matters immensely. My chiropractic role is to:

• Assess joint mobility—especially cervical and thoracic segments affecting scapular mechanics and distal stress
• Correct segmental dysfunctions that perpetuate aberrant loading
• Address shoulder girdle control, scapulothoracic rhythm, and proximal stability
• Normalize wrist and hand biomechanics affecting extensor load

The reasoning is clear:

• Tendons become symptomatic when loaded beyond their adaptive capacity
• Joint restrictions or instability upstream or downstream can shift forces to vulnerable tendons
• By restoring mobility and stability, we reduce aberrant loads and facilitate healing

I use precise joint adjustments, soft tissue mobilization, and neuromuscular re-education to recalibrate the system. This complements fenestration by ensuring the newly healing tendon experiences appropriate, not chaotic, stresses.

Rehabilitation: The Load Is the Medicine

• Key terms: isometrics, eccentrics, heavy slow resistance, tempo control, BFR

After fenestration (with or without injectate), a structured rehab program is essential:

• Phase 1: Acute Modulation

• • Relative rest for 48–72 hours based on procedure specifics
  • Gentle range-of-motion and isometrics to maintain neuromuscular activation
  • Pain target: mild discomfort allowed; avoid sharp pain

• Phase 2: Early Loading

• • Isometric holds (e.g., wrist extension positions) to reduce pain and maintain tendon stiffness.
  • Transition to eccentrics—slow, controlled lowering phases
  • Mechanotransduction signals fibroblasts to align collagen along lines of stress

• Phase 3: Progressive Overload

• • Heavy slow resistance (HSR) if appropriate—3–4 sets, 6–8 repetitions, controlled tempos
  • Tempo emphasis—3–5 seconds eccentric to enhance tendon remodeling
  • Blood flow restriction (BFR) as needed to stimulate adaptations with lower loads when pain or joint stress is a concern

• Phase 4: Return to Function

• • Sport- or task-specific drills
  • Plyometric or elastic energy storage exercises if indicated (e.g., for Achilles)
  • Continuous monitoring of pain during and after sessions, aiming for acceptable ranges with steady progress

Why this works:

• Tendons respond to tension more than to rest alone
• Appropriate loading channels healing collagen into functional, aligned fibers
• Isometrics can provide analgesia through cortical and spinal mechanisms
• Eccentrics and HSR enhance tendon stiffness, resilience, and functional capacity

We tie this progression to patient goals, whether it is lifting children without pain, returning to tennis, or resuming manual work tasks.

Personal Injury and Occupational Care: Documentation and Function

• Key terms: causation analysis, functional capacity, return-to-work

In personal injury contexts, clarity and documentation are critical:

• Mechanism of injury analysis—acute overload vs. cumulative microtrauma
• Baseline function and objective measures—grip strength, dynamometry, range of motion
• Work task analysis—job demands, ergonomics
• Return-to-work plans—graded transitions, accommodations, re-injury prevention

We collaborate with case managers, attorneys, and employers when appropriate, ensuring our evidence-backed interventions align with functional outcomes and legal documentation requirements. Needle fenestration can shorten downtime when paired with smart load progression and workplace modifications.

Patient Education: Shared Decision-Making

• Key terms: informed consent, expectation setting, timelines

Patients must understand:

• The goal: convert chronic tendon pathology into a healing phase
• Expected discomfort during and after the procedure
• Timelines: improvement may be gradual over weeks to months
• The importance of rehab adherence and biomechanical corrections
• The role of sleep, nutrition, and stress in healing

With this alignment, patients become active participants, not passive recipients.

A Closer Look at Tennis Elbow: ECRB Fenestration

Let’s walk through a procedure similar to what you might have seen in clinical demonstrations.

• Setup: The lateral elbow is prepped; the ultrasound transducer is placed to visualize the extensor tendon origin with the hypoechoic area
• Anesthesia: Anesthetize the superficial plane with 1% lidocaine via a 27-gauge needle.
• Needle: Use a 22–25 gauge needle. We approach in-plane, long-axis, with bevel up.
• Fenestration: Controlled passes are made—often 15–50—covering the lesion by minor redirections, both superficial and deep within the lesion. As passes progress, the tendon often feels softer.
• Transducer rotation: Turning 90 degrees allows evaluation of medial-lateral coverage.
• Adjunct: If planned, dextrose prolotherapy is injected to augment the inflammatory signal.
• Completion: The needle is withdrawn; compressive measures may be applied; post-care instructions are provided.

We emphasize precise visualization: at all times, I keep the needle tip in view to ensure exact lesion targeting and safety.

Integrative Functional Medicine: Healing Capacity from Within

• Key terms: anti-inflammatory nutrition, collagen substrates, sleep, stress resilience

Tendon healing is not only local—systemic factors matter. Our functional medicine approach includes:

• Nutrition:

• • Adequate protein to support collagen synthesis
  • Vitamin C, copper, and zinc as cofactors for collagen crosslinking
  • Omega-3 fatty acids for inflammation modulation
  • Consider gelatin or collagen peptides pre-loaded before tendon exercises to improve collagen synthesis potentially

• Glycemic control:

• • Hyperglycemia impairs collagen quality; we address insulin resistance if present

• Sleep:

• • Growth hormone and tissue repair processes rely on robust sleep

• Stress:

• • Excess cortisol can impede healing; we provide stress management strategies

This holistic layer ensures the local procedure has the systemic support needed for durable outcomes.

Clinical Observations: From the Field

Drawing from my clinical observations, which I discuss on our platforms, including Sciatica Clinic and my professional updates:

• Patients with persistent lateral elbow pain often harbor proximal chain dysfunctions—thoracic hypomobility, scapular dyskinesis, cervical restrictions—that must be addressed.
• Grip retraining and ergonomic coaching are essential adjuncts, especially for keyboard-intensive or tool-intensive occupations.
• Early isometric interventions can reduce pain and facilitate adherence to later-stage eccentrics.
• For athletes, return-to-play timelines improve with clear milestones that reflect objective metrics (e.g., pain-free grip strength benchmarks, functional tests).

These observations align with the broader literature and emphasize the need for a comprehensive plan rather than a single procedure.

Evidence-Based Perspective: What the Research Suggests

• Needle fenestration has been reported to improve pain and function in chronic tendinopathies when coupled with structured rehab.
• Dextrose prolotherapy and PRP show variable results across studies; selection should be individualized.
• Ultrasound guidance enhances accuracy and may improve outcomes by ensuring lesion coverage and minimizing risk.
• Load management and progressive tendon loading are crucial determinants of success.
• Integrative approaches that address biomechanics and systemic factors yield more durable results.

We stay current with leading researchers and evolving methodologies, applying what works in the clinic while respecting patient preferences and constraints.

Post-Procedure Care and Milestones

• First 72 hours: swelling and soreness are common; use relative rest, cold packs as needed; avoid NSAIDs if we want to preserve the inflammatory signal (decision individualized by Dr. Cardenas).
• Days 3–7: initiate isometrics; maintain gentle range.
• Weeks 2–4: progress to eccentrics; monitor pain using a simple 0–10 scale; keep within tolerable ranges.
• Weeks 4–8: transition to HSR; integrate functional patterns.
• Beyond 8 weeks: return to sport/work tasks; continue preventive strategies.

We reassess at defined intervals using ultrasound, patient-reported outcomes, and functional tests to steer the plan.

Frequently Asked Questions

• Tendons do not heal in isolation—joint angles, segmental motion, and motor control influence how force is transmitted.
• With integrative chiropractic care, we reduce pathologic stress on the healing tendon and align the system for success.

This does not replace medical oversight; it complements it, reflecting the synergy of disciplines in modern musculoskeletal care.

Practical Tips for Patients

• Follow the pain rules: mild is acceptable; sharp, persistent pain demands modification.
• Trust the process: remodeling takes weeks to months, but each phase builds on the last.
• Prioritize sleep and protein: your tendon is rebuilding—give it the tools.
• Do your rehab: consistency trumps intensity early on.
• Communicate: keep us informed about responses and barriers.

We are your team—MD, DC, rehab specialists—committed to your outcome.

Summary: Precision, Biology, and Integration

Needle fenestration is a precision tool that can rekindle healing in chronic tendinopathy. Its strength lies not just in the needle, but in the system that surrounds it: ultrasound visualization, medical oversight, integrative chiropractic optimization, rehabilitative science, and functional medicine. Together, these elements convert a stubborn tendon into a partner in healing—structured, supported, and guided by evidence and experience.

Our partnership—Dr. Maria Guadalupe Cardenas, MD, and me, Dr. Alex Jimenez, DC—reflects a contemporary, patient-centered model designed to maximize safety, efficacy, and durability. Whether you are an athlete, a clinician, or someone seeking relief from persistent tendon pain, this path offers a measurable, thoughtful way forward.
