孩子膝蓋疼有哪些原因膝蓋疼是兒童青少年常見的癥狀，很多家長都會說這是“長個”，補補鈣就行了，不用去醫(yī)院。然而事實真的如此嗎？新聞里孩子說腿疼，家長沒重視，最后病情惡化必須截肢的案例屢見不鮮。可見“腿疼”這一常見的癥狀背后可不一定是生長痛，還有不少病因如果不及時處理確實會危及肢體甚至生命，家長和醫(yī)生都應引起足夠的重視。膝蓋疼痛的孩子就診時，應根據(jù)病情緊急程度按照以下順序考慮診斷：威脅肢體甚至生命的疾病、髖關節(jié)病變、關節(jié)腔積液相關病因、勞損、良性骨腫瘤，除外以上疾病后才能考慮生長痛。面對孩子主訴膝蓋疼，醫(yī)生首先要判斷有沒有威脅肢體甚至生命的嚴重疾病，主要包括細菌感染和惡性腫瘤。▼化膿性關節(jié)炎膝關節(jié)是兒童化膿性關節(jié)炎最常累及的部位。化膿性關節(jié)炎一般表現(xiàn)為突發(fā)的逐漸加重的膝關節(jié)痛，伴有發(fā)熱，查體可發(fā)現(xiàn)膝關節(jié)腔積液、皮溫升高、紅腫、活動受限。膝關節(jié)正側位X線、實驗室檢查可以幫助診斷，MRI能夠發(fā)現(xiàn)附近的骨髓炎。化膿性關節(jié)炎一般需要切開引流及長期抗生素治療。▼骨髓炎骨髓炎患兒一般會因疼痛出現(xiàn)跛行，全身癥狀比化膿性關節(jié)炎輕。查體可發(fā)現(xiàn)關節(jié)壓痛和活動受限，可能存在反應性積液。相關檢查也是X線、實驗室檢查，如果MRI發(fā)現(xiàn)周圍軟組織或骨膿腫，則需要進行手術清創(chuàng)。骨髓炎的治療主要為長期抗生素。▼惡性腫瘤兒童惡性腫瘤發(fā)病率總體不高，但是有幾種惡性腫瘤可能會表現(xiàn)為膝蓋疼痛，包括原發(fā)骨腫瘤（尤文肉瘤、骨肉瘤、原發(fā)骨淋巴瘤）、軟組織腫瘤（橫紋肌肉瘤、纖維肉瘤、脂肪肉瘤）和白血病。如果兒童出現(xiàn)膝蓋疼痛、全身癥狀、夜間痛或可觸及腫塊，需要進行腫瘤評估，首先是膝關節(jié)、股骨、脛腓骨的X線正側位。尤文肉瘤的特征性表現(xiàn)為骨膜“洋蔥皮樣”改變。骨肉瘤的特征表現(xiàn)為“日光放射狀”，即鈣化的血管從病變向周圍放射。白血病可表現(xiàn)為骨質減少、干骺板受累、骨膜新骨形成、斑塊狀溶骨、硬化、溶骨硬化混合病變、浸潤性破壞等。根據(jù)可疑程度，可以進一步進行MRI、炎癥免疫指標檢查等。除外以上最嚴重的疾病之后，還需要考慮是不是髖關節(jié)病變引起的膝關節(jié)痛。如果髖關節(jié)或大腿疼痛與膝蓋內側疼痛同時出現(xiàn)，或者髖關節(jié)不能屈曲90度、不能內旋10度，或關節(jié)活動時有疼痛，則一定要考慮髖關節(jié)病變。此時一定避免讓孩子承重，直到骨盆X線正側位結果證明沒有髖關節(jié)病變。股骨近端骨骺滑脫是指股骨近端骨骺與干骺端分離，常見于10~16歲兒童。查體發(fā)現(xiàn)或X線明確診斷的患兒嚴格不能負重，并進行急診外科處理。除外髖關節(jié)疾病后，其他需要處理的病因還包括外傷后或非外傷（炎癥反應和非細菌性感染）導致的積液。▼外傷后積液如果孩子是在急性外傷之后出現(xiàn)膝關節(jié)腫脹，查體發(fā)現(xiàn)關節(jié)積液，則需要高度懷疑關節(jié)內紊亂，具體包括骨折（脛骨、股骨、腓骨、髕骨）、軟骨損傷、交叉韌帶損傷、半月板撕裂、髕骨半脫位或脫位。此時一定需要進行膝關節(jié)MRI平掃。▼非外傷后積液幼年特發(fā)性關節(jié)炎是一組特發(fā)的自身免疫病，引起炎癥性關節(jié)炎。全身型（又稱Still病）表現(xiàn)為間歇熱、皮疹和關節(jié)炎，每天熱峰1~2次。皮疹為橙紅色移動性斑疹，多與發(fā)熱一起出現(xiàn)，也可能出現(xiàn)淋巴結腫大和肝脾腫大。白細胞和血小板增多、貧血、ESR升高，ANA和RF多為陰性。全身型治療首先使用NSAIDs，可以升級為激素、甲氨蝶呤和其他生物藥物。少關節(jié)型多見于2~5歲女孩，累及不超過4個非對稱大關節(jié)。一般表現(xiàn)為跛行和關節(jié)腫脹，沒有疼痛或全身癥狀。治療一般用NSAIDs和關節(jié)腔內注射激素。多關節(jié)型至少有5個對稱小關節(jié)受累。另外還有銀屑病關節(jié)炎和附著點炎相關關節(jié)炎。感染性關節(jié)炎：常見的非化膿性感染性關節(jié)炎包括萊姆病關節(jié)炎、淋病性關節(jié)炎、病毒性關節(jié)炎。最常見的引起病毒性關節(jié)炎的病毒為細小病毒、乙肝病毒、丙肝病毒和風疹病毒。病毒感染后關節(jié)炎和關節(jié)痛一般作為前驅癥狀出現(xiàn)，病毒性關節(jié)炎治療可以使用冰敷和抗炎藥。▼膝關節(jié)急慢性勞損膝關節(jié)急慢性勞損根據(jù)關節(jié)疼痛的部位（膝關節(jié)前、后、內側、外側）可鑒別多種不同的病因，一般都是因為不良的機械作用導致的膝關節(jié)骨、軟骨和軟組織損傷。▼良性骨腫瘤大多數(shù)良性骨腫瘤都沒有癥狀，偶爾會出現(xiàn)腫物、夜間痛、骨骼壓痛。良性骨腫瘤有時會導致病理性骨折、引起疼痛或局部侵襲。良性骨腫瘤X線一般為邊界清楚或硬化，病變和正常骨組織分界明確，沒有骨皮質破壞，不會侵入軟組織。一些病變（如非骨化性纖維瘤和骨軟骨瘤）可以臨床觀察，而病變較大或出現(xiàn)病理性骨折、局部侵襲性、持續(xù)疼痛則需要評估手術切除。▼生長痛生長痛是兒童膝蓋疼痛最常見的病因，是一種除外性診斷，病因不明，但是目前認為是一種壓力性損傷。其臨床特點包括：見于學齡前或學齡兒童；雙側肢體疼痛；間歇痛；夜間痛；晚上孩子睡覺時疼醒，早晨好轉，白天無活動受限。生長痛一般出現(xiàn)于大量運動后幾天。生長痛與其他慢性疼痛（例如頭痛或腹痛）和家族生長痛史相關。查體無明顯異常。如果病史和查體符合典型的生長痛表現(xiàn)，則不需要進行其他檢查。但是一旦醫(yī)生懷疑其他可能的病因，則應進行X線和實驗室檢查。生長痛的治療可選擇冷敷、熱敷、按摩和抗炎藥。生長痛是自限性疾病，孩子和家長都不必過分擔心。如果疼痛發(fā)生較頻繁，可以在睡前預防性使用抗炎藥。
