Abstract：
OBJECTIVE: To determine the outcome of tenoscopically guided palmar/plantar annular ligament (PAL) desmotomy to treat PAL constriction without concurrent intrathecal soft-tissue injury, notably of the digital flexor tendons and manica flexoria.
METHODS: Retrospective multicenter cohort study.
METHODS: Sixty-five horses.
METHODS: Horses from four UK equine hospitals, with digital flexor tendon sheath (DFTS) tenosynovitis, which underwent tenoscopically guided PAL desmotomy for treatment of PAL constriction between 2017 and 2022 were included. All horses had lameness isolated to the DFTS/PAL, and PAL constriction was diagnosed tenoscopically when there was difficulty maneuvering the endoscope into or through the fetlock canal. Horses with tearing of the digital flexor tendons and/or manica flexoria, or any other intrathecal pathology, were excluded. Follow up was via structured telephone questionnaire.
RESULTS: Follow up (median 25 months) was available for 61 horses with cobs and ponies predominating. Forty-two returned to their previous level of work, or a higher level, postoperatively and 50 owners were satisfied with the outcome of surgery. Eleven horses returned to lower level exercise, and six were retired/euthanized as they did not regain soundness. Fifty-two horses achieved soundness (median 3 months postoperatively).
CONCLUSIONS: Tenoscopically guided PAL desmotomy for the treatment of PAL constriction in the absence of intrathecal soft tissue injury had a good prognosis for return to previous levels of exercise in a UK horse population.
CONCLUSIONS: The prognosis for horses undergoing tenoscopically guided PAL desmotomy to treat PAL constriction in the absence of intrathecal injury is better than previously described. Cobs and ponies seem to be predisposed to PAL constriction in agreement with the previous literature.

摘要：
目的：为了确定在不并发鞘内软组织损伤的情况下，采用肌腱镜引导掌底环状韧带（PAL）切开术治疗PAL狭窄的结果，尤其是数字屈肌肌腱和屈肌。
方法：回顾性多中心队列研究。
方法：65匹马。
方法：来自英国四家马医院的马，手指屈肌腱鞘（DFTS）腱鞘炎，纳入了2017年至2022年期间接受了肾镜引导下PAL切除术治疗PAL狭窄的研究。所有马匹都与DFTS/PAL隔离，当难以将内窥镜操纵进入或穿过fetlock管时，通过声波镜诊断为PAL收缩。手指屈肌肌腱和/或屈肌撕裂的马，或任何其他鞘内病变，被排除在外。随访是通过结构化电话问卷进行的。
结果：对61匹以玉米棒和小马为主的马进行了随访（中位数为25个月）。四十二人恢复了以前的工作水平，或更高的水平，术后和50名患者对手术结果感到满意.11匹马恢复低级运动，和6人退休/安乐死，因为他们没有恢复健康。52匹马达到健全性（术后中位数3个月）。
结论：在没有鞘内软组织损伤的情况下，经肾镜引导的PAL切开术治疗PAL狭窄具有良好的预后，可以恢复英国马群以前的运动水平。
结论：在没有鞘内损伤的情况下，接受腱镜引导下PAL切除术治疗PAL狭窄的马的预后比以前描述的要好。与先前的文献一致，小马和小马似乎倾向于PAL收缩。
