手指鞘管区异体滑膜肌腱与自体非滑膜肌腱移植的比较学研究

目的比较手指鞘管区异体滑膜肌腱与自体非滑膜肌腱移植结果并对异体滑膜肌腱在鞘管区的移植进行评估.方法对在手指屈肌腱鞘区内应用异体滑膜肌腱与自体非滑滑膜肌腱移植的病例,术后进行3个月以上的随访.评定标准为关节活动范围（TAM法）、力量,及二期肌腱松解率.结果异体滑膜肌腱移植280例,优良率达57.0%,较差或差为11.0%.松解率为32.0%,松解后总优良率达93.0%.自体非滑膜肌腱移植98例,优良率达43.0%,较差或差为9.0%.松解率为49.0%,松解后总优良率达94.2%.两者的最终结果无明显差异.结论肌腱表面结构影响肌腱的营养途径及肌腱愈合质量,滑膜肌腱表面结构则有益于肌腱营养与较快建立起血循环及组织液的渗透,是减少肌腱术后粘连再次松解的主要因素.     

Fibroma of tendon sheath involving the patellar tendon

Fibroma of tendon sheath is a benign soft-tissue tumor that usually arises in association with tendons or ligamentous structures. We describe, what is, to the best of our knowledge, the first reported case of fibroma of tendon sheath involving the patellar tendon.     

Active tendon implants in flexor tendon reconstruction

Forty-five active flexor tendon implants were evaluated after placement in scarred tendon beds of digits II through V. The implant is constructed of silicone rubber with a Dacron core, terminating in a loop proximally and a metal plate distally. Modification of the implant during the period of study has improved its reliability and longevity. The improvement in total active motion (TAM) averaged 72 degrees during implant functioning (stage I) in a group of digits that before operation were classified as 78% Boyes grade 5 (salvage). Complication rate during stage I was 11% (5 out of 45). Of the 27 digits evaluated after implant replacement by tendon autograft (stage II), there was an overall improvement in 62 degrees total active motion with 70% of digits being Boyes grade 5. Many of the complications were believed to be avoidable with experience. This study demonstrates the feasibility of an active tendon implant and the possibility of a permanent prosthesis.     

Mechanisms of collagen fibril alignment in tendon injury: From tendon regeneration to artificial tendon

The process by which collagen fibrils are aligned following tendon injury remains unknown. Therefore, we analyzed the process of tendon regeneration by transmission electron microscopy, using a film model method. In mice, the Achilles tendon of medial head was transected. On day 3, after only the proximal end of the transected tendon was placed on film and kept in vivo, a translucent substance containing granules, called tendon gel, was secreted. On day 5, the granules assembled in a loose (L) layer, and coalesced tightly in a dense (D) layer, forming an L‐D‐L layered pattern. On day 10, granules showed high electron density in H layers, which developed into D‐H‐D layers on day 13. The distal end was placed on film to face the proximal end. On day 10, the tendon gel showed a D‐H‐D layer pattern. On day 11, mechanical stress from muscular constriction changed the tendon gel to aligned collagen fibrils (6 ± 2 nm in diameter). Thereafter, the diameter of the fibrils increased. Tendon gel harvested on day 5 or day 10 was pulled manually or by hanging weights (about 0.6 MPa). Aligned collagen fibrils (32 ± 7 nm in diameter) were created by traction using tendon gel harvested on day 10. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Experimental tendon grafting within intact tendon sheath

A chicken toe experimental model was used to study the fate of flexor tendon grafts, introduced into intact tendon sheaths. After perfusion of the limb by India Ink, the vascular pattern of the graft and the synovial sheath could be identified. The grafts showed no or few adhesions to the sheath. With time, there was a conversion from a diffuse superficial vascular pattern towards a concentration of vessels on the dorsal aspect of the graft. In a control group, where the sheath had been resected, adhesions were more apparent, and could be observed still after 16 weeks. These results are in complete agreement with previous experimental findings and further confirm the importance of an intact tube system in the digit.
