长伸肌副腱的解剖学特征及其与外翻畸形的相关性研究

目的观察■长伸肌副腱的解剖学特征,并分析该副腱与■外翻畸形的相关性。方法 90例(左、右各45例)经10%福尔马林溶液灌注固定的人体下肢标本,解剖踇长伸肌及其副腱;采用游标卡尺及量角器,测量副腱的长度、宽度、副腱角及其止点宽度,测量■外翻角;分析上述测量结果与外翻畸形的相关性。结果 (1)86例标本具有■长伸肌副腱,45例标本出现外翻畸形;(2)■长伸肌副腱的数量如下:1支80例、2支5例;与■短伸肌腱共同止点变异1例;(3)■外翻组副腱的长度、宽度、副腱角及止点宽度分别是(85.02±22.27)mm、(1.84±1.64)mm、(7.83±3.28)°及(9.08±2.71)mm;正常组副腱的长度、宽度、副腱角及止点宽度分别是(97.51±30.99)mm、(1.62±0.49)mm、(5.99±3.95)°及(9.09±3.09)mm。与正常组相比,■外翻组副腱角明显增加(P=0.04,t=-2.097)。在所有标本中,副腱角与■外翻角呈正相关(P=0.007,r=0.317)。结论人■长伸肌副腱的出现,与■外翻具有一定相关性,却不是导致■外翻畸形的重要原因。对■长伸肌及其副腱的观察,是对既往研究的补充,也为副腱的临床应用提供理论依据。

长伸肌瓣的解剖学基础

在30个成人下肢标本上观察了长伸肌的形态、血供和神经支配。测得肌长23.1cm。该肌由7-17支胫前动脉横向分支供应,肌下份有腓动脉穿支发出补充,动脉主要从肌的内侧入肌。腓深神经约发出2支分支分布该肌,也是从肌内侧进入肌内。根据观察结果我们认为长仲肌瓣倒置治疗小腿中下份慢性骨髓炎及开放性胫骨骨折,似为较理想的供肌。     

小指伸肌腱的解剖学研究进展

应用小指固有伸肌腱（EDQ）转位重建拇对常功能术已成为一种成型且普及的术式，但术后可出现小指伸直不全或障碍并发症，因此从解剖学角度研究小指伸肌腱有重要的临床指导意义。目前，对小指伸肌腱的研究观点尚不一致，其主要分歧表现在对小指指总伸肌腱（EDCs）和腱结合（JT）的看法上，在形态解剖学和应用解剖学上很易混淆。在手背侧伸向小指的伸肌腱主要由EDCs、EDQ及伸指腱器结构组成。本将就EDCs及JT解剖学研究的相关内容作一综述。

用40例新鲜成人尸体足标本,作巨微解剖.透明标本和组织切片方法,测量了趾长伸肌腱各项数据,详细报道了其系膜的分支及位置.趾长伸肌腱囊外近侧段的血供为肌血管的延伸;滑液囊及肌腱囊内段血供主要来自胫前动脉、跗上外侧动脉和足背动脉;肌腱囊外远侧段血供来自跖骨背侧动脉。临床切取不同部位带血管蒂趾长伸肌腱时可以此为据.本文还特别强调了跗上外侧动脉在切取滑液囊肌腱复合瓣中的作用.

Examination of the accessory tendons of extensor hallucis longus muscle in fetuses

There are various data about the incidence of accessory tendons (AT) of extensor hallucis longus (EHL) muscle; however, their function is unknown. This study aimed to determine the incidence and morphometric features of the AT of EHL muscle in fetuses in order to provide more information to discuss its possible function. Forty-five fetuses (26 female and 19 male) were used in this study. Fetuses were grouped as Group A (16-21 weeks), Group B (22-27 weeks), and Group C (28-34 weeks) according to their age. In 23 (51%) out of 45 fetuses, there were AT. These were bilateral in 15 fetuses (65%) and unilateral in eight fetuses (35%). Fifty-two percent of the fetuses in group A, 43% in group B, and 67% in group C had AT. AT were observed in 14 female (54%) and 9 male (47%) fetuses. In all cases, the AT were always diverging to the medial side of the main EHL tendons and attached to the metatarsophalangeal joint capsule distal to the joint space. Significant correlations were observed in this study between EHL and AT widths as well as between EHL width and EHL-AT distance on both sides. The present study is the first to provide morphometric data about the AT of EHL muscle in fetuses which will be of use in understanding their function, particularly in biomechanics of the great toe.     

Anomalous tibialis posterior muscle as an etiologic factor of hallux valgus

The role of an anomalous tibialis posterior (TP) tendon in the etiology of hallux valgus (HV) deformity was investigated in four stages: clinical, anatomical, neurological, and operative. In the clinical stage, the patients were instructed to planter flex and invert the foot to contract the TP tendon. Attempts to correct the deformity passively were not possible and resulted in, moderate pain in all patients (197 feet). When the foot was in dorsiflexion and everted (TP tendon was relaxed) the deformity was easily corrected without any pain in 196 feet (99.5%). In the second stage (anatomical), 10 cadavers (20 feet) with HV deformity and 10 cadavers (20 feet) without any foot deformity were dissected. An abnormal expansion of TP tendon into the oblique part of adductor hallucis was found consistently in all HV feet. The tendinous expansion was absent in all normal feet studied. Also when traction was applied to TP tendon, an increase in the metatarsophalangeal (MP) angle of the big toe was observed in all HV feet, but not in the control group. In the third group (neurological), faradic stimulation was applied to the TP muscle in 7 patients with HV deformity and 7 without deformity. The MP angle was increased in HV patients, but no change was observed in the control group. In the fourth stage, 11 patients (18 feet) surgically operated for HV deformity by proximal metatarsal osteotomy and excision of the band anchoring TP tendon to the oblique part of adductor hallucis. The results were excellent in 10 patients (17 feet) even after a minimum 2.5 year follow-up. Also, in two patients who were operated by different procedures with poor results, the TP tendon was lengthened by Z-plasty and they were completely pain free. Our data show the dynamic role of anomalous expansions of the TP tendon into the oblique part of adductor hallucis muscle in HV patients. We suggest this expansion be excised in addition to other operative procedures selected for the surgical treatment of HV patients. © 1994 Wiley-Liss, Inc.

Insertion of the tendon of the tibialis anterior muscle in feet with and without hallux valgus

The insertion of the tendon of the tibialis anterior muscle may be related to pathologic changes of the foot and, in particular, hallux valgus. Morphologic data should enable evaluation of such a relationship and perhaps offer a basis for improved therapy. One hundred fifty-six embalmed feet, including 27 with hallux valgus, were examined. The tendon of the tibialis anterior muscle was dissected and measurements were made, including the width of the insertion on the first metatarsal and medial cuneiform. Distal-superficial and proximal-deep slips of the tendon twisted around each other. Two specimens presented with an insertion only on the medial cuneiform; in two other cases the insertion was limited to the first metatarsal; in one case the tendon inserted into the navicular and the medial cuneiform; in all other cases, the tendon inserted into the medial cuneiform and first metatarsal. The insertion was mainly located along the plantar margin of the medial side of the foot; some of the proximal-deep fibers also passed onto the plantar surface. Fibers inserting on the first metatarsal bone can outwardly rotate the first ray, which is opposite to the inward rotation of the first ray in hallux valgus. In all feet with hallux valgus these fibers were present. Therefore, it is unlikely that this deformity develops because of a specific type of insertion of the tendon of the tibialis anterior muscle, and any therapeutic approach altering the attachment of the tibialis anterior tendon would cause no biomechanical improvement.     

The clinical surface anatomy anomalies of the palmaris longus muscle in the Black African population of Zimbabwe and a proposed new testing technique

The presence of the palmaris longus muscle (PLM) is highly variable. Rates of absence vary from 0.6% in the Korean population to as high as 63.9% in the Turkish population. The tendon of PLM may be absent on one or both forearms, may have duplicated tendons on one forearm or may be laterally shifted to the extent that the tendon of the PLM lies superficial to that of flexor carpi radialis muscle. Among Black American populations, in which there is usually mixed ancestry, rates of absence are 3.5%. Only two studies have been performed on Black African populations: in Republic of Congo and Uganda, and each showed widely differing rates of absence of 3.0% and 14.6%, respectively. In this study, a total of 890 Black Zimbabwean subjects in Harare aged between 8 and 13 years, were examined for clinical surface anatomy anomalies of the tendon of PLM. The results showed that the tendon of the PLM was absent unilaterally in 0.9% of the population, and bilaterally absent in 0.6% with an overall rate of absence of 1.5%. Other variations noted were a laterally shifted PLM in 1.1% of subjects and duplicated tendons on one forearm, which was the least prevalent anomaly, in 0.2% of subjects. The author proposes a new technique to test the tendon of PLM, which combines resisted thumb abduction and resisted wrist flexion. The proposed technique capitalizes on the role of the PLM as an important abductor of the thumb. Clin. Anat. 22:230–235, 2009. © 2009 Wiley‐Liss, Inc.
