In the dysfunction of large muscles of the leg, tendon transfer surgery is found to be very helpful in restoring the normal function of these muscles. The tendons involved in the chiasma plantare play a major role in this regard.
The present cadaveric study has been carried out in cadavers presenting pes cavus.
Cadaveric feet presenting pes cavus were identified based on their foot prints. All these tendons and their interconnections were subjected to histological procedures. The sections of the tendons were stained with hematoxylin and eosin in order to identify the underlying pathologies in the tendons.
Various types of tendinous interconnections between the tendons of flexor digitorum longus and flexor hallucis longus were noted. The histological findings showed infiltration of lymphocytes in the tendon sheath indicating tenosynovitis and tendinitis. This could be attributed to the compression of the tendons. A few tendons were also stretched due to the skeletal framework of the foot in pes cavus. The bones along the medial longitudinal arch in pes cavus feet could tend to develop spurs or elongated tuberosity that could impinge on the tendons causing the tendons to stretch and elongate.
In harvesting the tendons for grafting, the surgeons must be aware about the pathologies involved, such as tendinitis or tenosynovitis, in order to reduce the time taken for the healing of the graft post-surgery. These variations and histological findings can sub-serve as an efficient guide for the restoration of non-functioning muscles of the lower limb.
在腿部大肌肉功能障碍的情况下,肌腱转移手术被发现非常有助于恢复这些肌肉的正常功能。参与跟腱交叉的肌腱在这方面起着重要作用。
本尸体研究是在出现高弓足的尸体中进行的。
根据足迹确定出现高弓足的尸体。对所有这些肌腱及其相互连接进行组织学处理。对肌腱进行苏木精和伊红染色以确定肌腱中的潜在病变。
在趾长屈肌和踇长屈肌的肌腱之间观察到各种类型的肌腱连接。组织学发现表明,肌腱鞘内有淋巴细胞浸润,提示腱鞘炎和肌腱炎。这可能归因于肌腱受压。由于高弓足的足部骨骼框架,一些肌腱也被拉伸。高弓足足部内侧纵弓的骨骼可能会形成骨刺或延长的结节,这些骨刺或结节会压迫肌腱,导致肌腱拉伸和延长。
在采集肌腱进行移植时,外科医生必须了解涉及的病理学,如腱鞘炎或腱鞘炎,以减少手术后移植愈合所需的时间。这些变异和组织学发现可以作为恢复下肢非功能肌肉的有效指南。
