追加：第 17 节第 10 条，老人遛狗怎么牵绳

2026-10-09，issue #100「对养宠物的建议」拆出来的一处。主题是老人牵狗散步摔骨折。四问：老人遛狗在国内很常见；把绳子绕在手腕上、用伸缩绳放长是常见习惯，很少有人知道这会伤手、会被拽倒；动作是新的，全书原来只有第 2 节第 44 条（遛狗算进走路量）和第 8 节第 30 条（养狗必须牵绳），都不讲怎么牵；来源是美国疾控中心报告和同行评审论文。

全部数字只来自美国急诊监测（NEISS）和美国一家手外科门诊，国内没有找到同类统计。

1. 美国 65 岁以上牵狗散步摔骨折

  • 题录：Pirruccio K, Yoon YM, Ahn J (2019). JAMA Surg 154(5):458-459. https://doi.org/10.1001/jamasurg.2019.0061（PMID 30840050，PMC6537776）
  • 这是研究快报，Europe PMC 没有摘要，正文用无头 Chrome 带代理从 https://pmc.ncbi.nlm.nih.gov/articles/PMC6537776/ 取得。
  • 原文：「The annual number of patients 65 years or older presenting to US emergency departments with fractures associated with walking leashed dogs increased significantly between 2004 (n = 1671; 95% CI, 1111-2232) and 2017 (n = 4396; 95% CI, 3202-5590)」
  • 原文：「Most fractures occurred in women (78.6%; 95% CI, 74.9%-82.2%). Most patients sustained hip fractures (17.3%; 95% CI, 13.8%-20.7%), although the upper extremity was the most frequently fractured region overall (52.1%; 95% CI, 48.1%-56.1%); 28.7% of patients (95% CI, 23.7%-33.8%) required hospital admission.」
  • 原文（动作依据）：「advocating for preventive actions, such as obedience training to ensure dogs do not lunge while leashed, or suggesting smaller dog breeds for individuals contemplating ownership.」
  • 没收：讨论里「mortality rates approaching 30%」是作者引别人的髋部骨折死亡率，不是本研究的数，没写。

2. 全美急诊狗绳相关受伤

  • 题录：Forrester MB (2020). Am J Emerg Med 38(9):1782-1786. https://doi.org/10.1016/j.ajem.2020.05.082（PMID 32739848），摘要经 Europe PMC REST 取得。
  • 原文：「A dog leash was involved in 8189 injuries, resulting in a national estimate of 356,746 injuries and an estimated rate of 63.4 injuries per 1,000,000 population. Of these injuries, 193,483 resulted from a pull, 136,767 from a trip/tangle, and 26,496 from other or unknown circumstances. The total injury rate per 1,000,000 population increased from 25.4 in 2001 to 105.5 in 2018.」
  • 这份是全年龄的数，条目里写明是「和狗绳有关的受伤」，没说成老人。

3. 手外科门诊 443 例狗绳伤手

  • 题录：Plusch K, Givner D, Wiafe B, Lutsky K, Beredjiklian P (2026). Hand (N Y) 21(4):582-586. https://doi.org/10.1177/15589447241299128（PMID 39600039，PMC11600420），摘要经 Europe PMC，正文用无头 Chrome 从 PMC 取得。
  • 原文（摘要）：「We identified 443 patients that presented for a dog-leash-related injury.」「Surgery occurred following injury in 96 patients (21.6%).」「The majority of injuries were caused by the extremity catching in the leash while being pulled (337, 75.9%).」
  • 注意：正文结果段写的是「(334, 75.4%)」，和摘要不一致。条目按摘要写，说人话只写「约四分之三」。
  • 原文（动作依据）：「the results of our study suggest that a leash should never be wrapped around the hand or fingers, as a sudden pull can lead to the common types of injuries seen in our practice. Maintaining the leash firmly in the palm of the hand is the safest way to avoid injury to the finger and wrist. However, this does not necessarily reduce the risk of falls following a sudden lunge by the dog. With larger dogs especially, a shorter leash length reduces the amount of time for the dog to build up speed, reducing the possibility of a strong pull to the owner once the dog reaches the end of the leash. Additionally, longer leashes increase the possibility of the leash wrapping around other objects and creating a tripping hazard for the owner.」
  • 作者同时写明「our study data do not provide information related to prevention of these injuries」，所以这是建议，不是研究结论。备注里交代了「防不住被拽倒」这一句。

4. 美国疾控中心：和猫狗有关的跌倒

  • 题录：CDC (2009). MMWR 58(11):277-281（PMID 19325528）。https://www.cdc.gov/mmwr/preview/mmwrhtml/mm5811a1.htm，curl 带代理 403，无头 Chrome 带代理能取。注意 mm5811a2 是另一篇（钠摄入），别引错。
  • 原文：「an estimated average of 86,629 fall injuries associated with cats and dogs occurred in the United States each year during 2001--2006」「Nearly 7.5 times as many injuries involved dogs (76,223 [88.0%])」
  • 原文：「Twenty-six percent of falls involving dogs occurred while persons were walking them, and the most frequent circumstances were falling or tripping over a dog (31.3%) and being pushed or pulled by a dog (21.2%).」
  • 原文（动作依据）：「reinforcing American Veterinary Medical Association recommendations emphasizing obedience training for dogs ( 3 ) to minimize behaviors associated with falls (e.g., pushing or pulling).」

5. 伸缩绳

  • 任务原稿要求写「别用伸缩绳」。查下来没有一份来源直接比较伸缩绳和普通绳的摔倒风险。Rosa R, Buckley RE (2024). JAVMA 262(7):973-978. https://doi.org/10.2460/javma.23.11.0608 摘要原文：「there is a lack of information regarding dog size, breed, training status, the type of leash used at the time of injury」。
  • Europe PMC 能查到的伸缩绳文献只有眼外伤个案（Eye 1994、2012 的来信），讲的是绳子回弹打伤眼睛，和摔倒无关，没收。
  • 所以标题只写「绳子收短」，依据是手外科那篇的「shorter leash length」建议；备注写「伸缩绳放长了就是长绳」，并写明没有直接比较的研究。

6. 骨质疏松的老人别牵大狗

  • 任务原稿有这一句。来源里只有 Pirruccio 建议「正在考虑养狗的人挑小一点的狗」，以及手外科那篇「With larger dogs especially」收短绳。没有来源把骨质疏松和狗的大小连起来，所以标题没写「骨质疏松别牵大狗」，只在备注写了挑小狗的建议，骨质疏松改成指路到第 1 节第 39、40 条。

证据等级和收益量级

  • 证据等级 B：受伤数字是全国推算，可以量化；但三个动作（握在手心、收短、训练狗）都只是研究作者和美国兽医协会的建议，没有研究算过做了能少摔多少。
  • 收益量级凭判断定「小」：口径是死亡率（含骨折），阈值看相对降幅，这里没有任何降幅数据，只有受伤计数；按「只有替代终点」那一档定小。
  • 受益人：第 ② 档，父母和祖父母。
