High-Pressure Paint Gun Injury of the Thumb: A Case of Reconstruction Using a Reverse Thenar Perforator-Based Island Flap

Hand injuries due to high-pressure paint gun devices are rare but may lead to serious outcomes. The authors describe a case of a high-pressure injury of the thumb that was managed promptly and later reconstructed successfully with minimal functional deficit. A 39-year-old man with a high-pressure paint gun injury of the right thumb was referred. Though the external wound was small, X-ray and computed tomography images showed extensive spread of paint inside. The paint was removed through a wide skin incision. After 6 weeks, the surgical wound had completely healed, except for a defect around the interphalangeal joint with bone exposure. A reverse thenar perforator-based island flap based on the princeps pollicis artery was elevated and moved to the defect. After defect reconstruction, the patient recovered pinch and grasp function through physiotherapy. High-pressure paint gun injuries of the thumb can lead to significant functional deficits of the hand. A small skin lesion may cause the actual extent of damage to be underestimated, as extensive penetration of paint can cause severe damage to the soft tissues. Thus, immediate surgical removal of the paint and coverage of the remnant wounds with an appropriate flap are necessary.

An uncommon case of high-pressure paint gun injury to the orbit with multimodality evaluation and literature review.

High-pressure paint injection injury to the orbit is a rare type of orbital trauma. We present an unfortunate case of high-pressure paint injury to the right orbit of a young patient. High-pressure injection injury presents with a unique injury mechanism and resultant deep tissue damage. The superficial appearance of the entry site injury is deceiving; therefore, a thorough evaluation is necessary. Debridement is usually required if foreign body material is present. Antibiotics and steroids are commonly used in such cases.

High pressure paint gun injury of the index finger: a case report

Injuries to the hand secondary to high pressure paint guns are considered to be true hand emergencies. These rare injuries may have serious outcomes, and a critical step in their management is extensive debridement performed within the first six hours following injury. For this reason, their diagnosis should not be delayed, and the hand surgeon should be informed immediately to initiate appropriate treatment. In this report, the authors describe a patient who was injured with a chemical paint gun, and whose injury was not diagnosed in the emergency department. The patient subsequently developed tenosynovitis. His treatment is reported herein.

High-pressure paint gun injury: clinical presentation and imaging findings

High-pressure paint gun injuries are potentially devastating injuries that require emergent surgical incision and drainage. They result from erroneous equipment operation and accidental injection of a variety of substances at pressures high enough to breach the skin. The largely benign superficial appearance masks the extent of the underlying injury. In the absence of an appropriate history, the radiologist must recognize the characteristic radiographic findings and suggest the diagnosis to the clinician.

A Case of High-Pressure Paint Gun Injury to the Eyeball and Ocular Adnexa

Purpose: To report a case of high-pressure paint gun injury to the eyeball and ocular adnexa. Case summary: A 50-year-old woman was admitted after accidental high-pressure paint injection to her right eye while working. She complained of pain and severe swelling of the eyelids covered with paint. Slit lamp biomicroscopy showed multiple conjunctival lacerations, deposition of paint material on her conjunctiva, corneal edema and crystalline lens dislocation. Orbital computed tomography revealed infiltration of paint material into the retrobulbar space and rupture of medial rectus muscle. The paint was removed from the conjunctiva, Tenon’s tissue, and medial orbit after the medial rectus muscle was disinserted. On the second postoperative day, the wound was irrigated and pus was drained from the conjunctiva wound. Two months after the operation, the patient underwent cataract removal due to high intraocular pressure associated with lens dislocation. Six months after the operation, eyeball movement was improved except medial gaze, and the cornea was stable with moderate corneal haziness. Conclusions: In high-pressure paint gun injury to the eye, detail evaluation, prompt removal of the foreign body and proper management of complications are necessary.

Fibrohistiocytic tumor of the hand after high-pressure paintgun injury: 2 case reports

Injections from high-pressure, airless paintguns are uncommon industrial accidents that may result in acute injuries, usually to the nondominant hand. These injuries commonly require emergent management including immediate surgical debridement to avoid tissue necrosis and loss of hand function. Rarely oleogranulomas and squamous cell carcinoma have been described as late complications. Herein we describe 2 patients who developed fibrohistiocytic tumors several months after a high-pressure paintgun injury.

High‐pressure paint‐gun injury of the finger simulating giant cell tumor of tendon sheath

High-pressure paint guns deliver paint at approximately 3000 pounds per square inch. At this pressure, paint will penetrate the skin and spread quickly through fascial planes and tendon sheaths. The present case is that of a lesion from the finger of a 35-year-old white male in whom a history was initially unavailable. Histologic examination revealed diffuse fibrohistiocytic proliferation and giant cells, with numerous darkly pigmented, uniformly small-sized particles throughout the lesion. The initial impression was that of a giant cell tumor of tendon sheath. However, the pigment particles were negative for Perls stain, and polariscopic examination revealed clear refractile fragments. These findings raised the possibility that the lesion was the result of a traumatic event. On further inquiry, it was revealed that the patient had sustained a high-pressure paint-gun injury 1 year earlier. The simulation, histopathologically, of a giant cell tumor of tendon sheath by a high-pressure paint-gun injury has not, to our knowledge, been reported previously, nor has the histologic finding of small, uniformly sized pigment particles and polarizable refractile fragments in this particular type of injury.

Culture results and amputation rates in high-pressure paint gun injuries of the hand.

High-pressure paint gun injuries have been well described in the literature, and the use of antibiotics is recommended as part of their management. However, there is no scientific evidence to support the use of antibiotics. In addition, the type of paint injected (water- versus oil-based) has never been investigated to determine the extent of morbidity resulting from these injuries. This study examines the organisms cultured in wounds resulting from these injuries and whether the type of paint injected had an influence on amputation rates. Charts of 35 patients with high-pressure paint gun injuries to their hands were reviewed. The amputation rate was 50% with oil-based paints and 0% with water-based paints. Forty-seven percent of wound cultures were positive, with gram-negative bacteria found in 58% of isolates. Our findings support the use of antibiotics, which should cover both gram-positive and gram-negative organisms.
