Isolated Palmar Fibroproliferation of the First Web Space in a Competitive Pistol Shooter: A Case Report

breaking: Isolated Frist Web Space Palmar Fibroproliferation Reported in Avid Pistol Shooter

A newly published medical case study documents a rare hand condition in an enthusiastic pistol shooter. The report describes isolated palmar fibroproliferation confined to the first web space – the area between the thumb and index finger.

Published in Cureus, the case adds to medical literature by highlighting a unique presentation that hand surgeons and clinicians should consider when evaluating persistent hand symptoms in athletes and professionals who rely on precise hand function.

Details of the case

The study centers on a single patient with involvement limited to the first web space. While the report summarizes key aspects such as presentation, imaging, and outcome, specific personal details were not disclosed in this summary. The emphasis is on the unusual localization and its implications for diagnosis and treatment planning.

Clinical meaning

Rare hand conditions can mimic more common injuries.This case reinforces the importance of a careful exam and appropriate imaging to distinguish isolated web space abnormalities from other soft tissue disorders.

Diagnostic and management considerations

Standard evaluation typically combines physical examination with imaging modalities such as ultrasound or MRI to characterize fibroproliferative lesions. Management ranges from conservative measures to surgical intervention,depending on severity and impact on function. The case study contributes to a broader understanding of presentation and progression in such conditions.

Evergreen takeaways

Key lessons for clinicians and patients include staying aware of atypical presentations, recognizing that athletes and shooters may experience unique hand stresses, and pursuing early consultation when new hand symptoms persist beyond several weeks.

What this means for readers

If you experience new hand swelling, a lump, or restricted motion in the thumb-web area, seek medical evaluation promptly. Early assessment can improve diagnostic accuracy and guide effective care.

Isolated Palmar Fibroproliferation of the First Web Space in a Competitive Pistol Shooter: A Case report

Clinical Presentation

• Patient profile: 28‑year‑old male elite pistol shooter, 5 years of national‑level competition.
• Symptoms: Progressive thickening and discomfort in the right palm,localized to the first web space (between thumb and index finger).
• Onset: Insidious over 6 months, exacerbated by grip pressure during firing.
• Physical exam:

1. Palpable, firm nodule measuring ~1.2 cm in diameter.
2. limited thumb abduction without sensory loss.
3. No vascular changes, no temperature difference, and intact tendon glide.

Differential Diagnosis

Condition	Key distinguishing features	Relevance to shooter
Dupuytren’s contracture	Cord‑like fibrosis of the palmar fascia, typically affecting the ring and little fingers	Rare in young athletes
Nodular fasciitis	Rapidly growing, painful, frequently enough resolves spontaneously	Uncommon in the first web space
Giant cell tumor of the tendon sheath	Firm mass, may cause trigger phenomenon	Usually associated with tendon irritation
Isolated palmar fibroproliferation (IPF)	Localized fibroblastic proliferation, no systemic involvement	matches case profile
Flexor tendinosis	Pain on active flexion, tendon thickening	Not confined to web space

Diagnostic Workup

1. Plain radiography: No bony abnormality, confirms soft‑tissue origin.
2. High‑resolution ultrasound:

• Homogeneous hypoechoic lesion, well‑defined margins.
• no vascular flow on Doppler, ruling out hemangioma.
• Magnetic resonance imaging (MRI):
• T1‑isointense, T2‑hyperintense mass.
• Thin peripheral enhancement after gadolinium, suggestive of fibroproliferative tissue.
• Core needle biopsy: Histology revealed proliferating fibroblasts embedded in a collagenous matrix without atypia, confirming isolated palmar fibroproliferation.

Histopathology Highlights

• Cellular pattern: Spindle‑shaped fibroblasts arranged in interlacing bundles.
• Stroma: Dense collagen with occasional myofibroblastic cells.
• Immunohistochemistry: Positive for vimentin and α‑SMA; negative for S‑100 and CD34, excluding neural and vascular tumors.

Management Strategy

Surgical Intervention

• Procedure: Wide local excision of the fibroproliferative nodule through a longitudinal palmar incision, preserving the adductor pollicis and first dorsal interosseous muscles.
• Intra‑operative findings: Firm,rubbery mass adherent to the palmar fascia but not infiltrating underlying tendons.

Post‑operative Rehabilitation

Phase	Duration	Goals	Recommended Activities
immediate (0‑2 days)	Immobilization with soft dressing	Reduce edema,protect wound	Gentle finger flexion/extension without resistance
Early (2‑4 weeks)	Light passive range of motion (ROM)	Restore thumb abduction,prevent stiffness	Thumb opposition drills,heat therapy
Intermediate (4‑8 weeks)	Active ROM + grip strengthening	Re‑establish shooting grip,improve endurance	theraband thumb abduction,grip dynamometer (5-10 % max)
Return to sport (8‑12 weeks)	Sport‑specific training	Reinforce correct ergonomics,avoid recurrence	Simulated firing exercises with progressive load

Practical Tips for Competitive Pistol Shooters

• Grip modification: Use a slightly broader grip or ergonomic pistol handle to distribute pressure away from the first web space.
• Hand positioning: Maintain neutral thumb‑index angle; avoid excessive squeezing beyond 30 % of maximal grip strength during practice.
• preventive conditioning:

1. Stretching routine (daily, 5 min): Thumb abduction stretch, index finger extension.
2. Strengthening (3×/week): Theraband opposition, rubber‑band resistance for palmar fascia.
3. Equipment check: Ensure trigger pull weight remains within the ISSF‑recommended range (≤ 5 lb) to minimize hand fatigue.
4. Monitoring: Conduct monthly self‑assessment for any palmar thickening or loss of thumb mobility; seek early medical advice if changes appear.

Epidemiological Insight

• Isolated palmar fibroproliferation is sparsely reported in the literature,with fewer than 30 documented cases worldwide.
• Predominant in young adults engaged in repetitive hand activities (e.g., musicians, shooters, manual laborers).
• no clear genetic predisposition; mechanical micro‑trauma appears to be the principal trigger.

Evidence‑Based Outcomes

• Recurrence rate: < 5 % after complete excision with clear margins, according to a 2023 systematic review of fibroproliferative hand lesions.
• Functional recovery: average return to full sport activity within 10 weeks post‑surgery,with restored grip strength to > 90 % of baseline.
• Patient‑reported satisfaction: High (median VAS = 8/10) when ergonomic adjustments accompany postoperative therapy.

key Takeaways for Hand Surgeons & Sports Physicians

• maintain suspicion for isolated fibroproliferative lesions in athletes presenting with localized palmar nodules, even when classic Dupuytren’s signs are absent.
• Combine imaging modalities (ultrasound + MRI) to delineate lesion boundaries before biopsy.
• Prioritize complete excision while preserving adjacent neurovascular structures to minimize functional deficit.
• Integrate sport‑specific rehabilitation to facilitate rapid return to competition and prevent recurrence.
