Treatment is based on their removal. 2007 Jun;15(6):758-60. doi: 10.1007/s00167-006-0197-4. Plant thorn synovitis. Cahill N, King JD. Epub 2008 Sep 5. Plant thorn synovitis (plant thorn arthritis) is joint inflammation caused by a thorn puncturing the joint and leaving residual plant matter in the joint. Therefore, it is important for surgeons especially to be aware of the condition and have a high index of suspicion for those with refractory arthopathy, especially following a plant injury. [Google Scholar] Table 1 outlines the demographics from the included case reports. The patient developed cellulitis following the removal and had been taking cephalexin orally for 2 weeks at the time of her consultation. Presentation is typically delayed, with one case reporting a median of 68.5 days between the time of the injury and the onset of joint pain.2 There is no ideal diagnostic tool, and although ultrasound has been reported to be effective in visualizing fragments in some reported cases, most have been definitively diagnosed with plant thorn synovitis only at the time of surgical exploration.5 Furthermore, treatment to date has not shown any promise with conservative or medical management. I took the thorn out and four hours later my finger started throbbing and turned red with the swelling from plant thorn synovitis. This site needs JavaScript to work properly. Conclusion: Thorn synovitis diagnosis is based on the discovery of a foreign body. The patient began hand therapy to range the affected finger at 4 weeks postoperatively. Ormerod, AD, White, MI, Eastmond, CJ, Chesney, RB. This disease is attributed to a granulomatous inflammatory response to retained plant thorn fragments following a puncturing plant thorn injury.1,2 However, the mechanism by which retained plant thorn material triggers this inflammatory response remains unclear. 1984 Mar; 4 (2):175–179. 1,2 However, the mechanism by which retained plant thorn material triggers this inflammatory response remains unclear. 1 Cahill N, King JD. This challenge in diagnosis characteristically results in a lag of weeks to months before the diagnosis of plant thorn arthritis is made.16 Although initial symptoms have been reported to be indolent and transient, the inflammatory process can cause significant sequelae.6 Most commonly, the persistent inflammatory response damages the neighbouring articular structures, leading to arthritis.6 In the case presented, there was intraoperative evidence of articular erosion accompanied by radiologic evidence of decreased joint space, only 3 months from the initial trauma. 2007 May;26(5):849-51. doi: 10.1007/s10067-006-0482-0. Cracchiolo A, 3rd, Goldberg L. Local and systemic reactions to puncture injuries by the sea urchin spine and the date palm thorn. As such, future studies are necessary to assess risk factors for individuals who go on to develop plant thorn synovitis. Better not ignore a thorn prick. Plant thorn synovitis, also known as plant thorn arthritis, is a rare and commonly overlooked cause of arthritic disease. KARSHNER RG, HANAFEE W. Palm thorns as a cause of joint effusion in children. Clin Orthop 1963; 30: 188–93. Historically, it is considered aseptic and treated with removal of the intraarticular foreign body and affected synovial lining. This retrospective clinical study compares the results of extensive versus limited synovectomy at the time of palm thorn removal from a joint space. At the 10-day postoperative follow-up, there was significant improvement in pain, erythema, and swelling of the joint (Figure 4). Initial radiography and sonography imaging following the removal revealed no foreign bodies. Please read and accept the terms and conditions and check the box to generate a sharing link. 4.
