手术治疗跟距骨桥疗效观察

目的探讨跟距骨桥的手术治疗方法及疗效。方法 2008年7月-2010年10月,手术治疗跟距骨桥患者10例。男4例,女6例;年龄16～70岁,平均53.5岁。先天性骨桥2例,继发性骨桥8例。跟距中间关节面骨桥3例,后关节面骨桥7例。术前患者疼痛视觉模拟评分(VAS)为(9.0±0.4)分;根据美国矫形足踝协会(AOFAS)后足评分标准为(42.4±1.4)分。合并距下关节退变2例。8例单纯跟距骨桥患者行骨桥切除并脂肪组织植入,2例合并距下关节退变患者行骨桥切除联合距下关节融合术。结果术后切口均Ⅰ期愈合。8例获随访,随访时间12～36个月,平均18个月。末次随访时VAS评分为(2.0±0.7)分,与术前比较差异有统计学意义(t=6.425,P=0.000)。AOFAS后足评分为(86.9±2.3)分,与术前比较差异有统计学意义(t=7.634,P=0.000)。单纯骨桥切除者末次随访时X线片检查示无骨桥复发及关节退变发生,关节融合者X线片示达骨性融合。结论跟距骨桥根据不同发生部位和合并症,分别采用单纯骨桥切除或联合距下关节融合术可取得较好疗效。     

跟距骨桥分型与治疗的研究进展

跟距骨桥多发生于跟距关节内侧,在足跗骨畸形中占比最高,绝大多数患者无明显症状,发病时多表现为疼痛、距下关节活动障碍。跟距骨桥的分型多种多样,不同的分型对于临床的指导意义不同。目前临床上应用最广的是Rozansky分型,对临床治疗有一定指导意义;Lim分型则更为简单全面,而对于合并足部畸形或者骨关节炎推荐使用Blitz分型。在治疗方面,轻微症状患者建议保守治疗;保守治疗失败的患者可以选择关节镜下手术切除骨桥,而面积较大(>50%距下关节面)、多关节面骨桥、畸形严重的患者可选择切开手术,Ⅰ期或Ⅱ期处理合并平足畸形;对于多次关节镜或切开手术失败,合并严重骨关节炎或者复杂的跟距骨桥患者可选距下关节或三关节融合术,并矫正畸形。     

微创与开放跟距关节融合术治疗跟距关节炎的比较

目的对比应用经皮微创空心螺钉跟距关节融合术与传统开放跟距关节融合术治疗跟距关节炎的效果。方法自2007年3月至2012年3月,作者对跟距关节炎需行跟距关节融合术患者应用微创经皮空心螺钉植骨融合术(A组)治疗12例13足,应用踝关节外侧"L"形切口跟距关节融合术(B组)治疗14例14足。通过回顾性分析,对比两种术式手术时间、术中出血量、术后并发症、术后足踝功能评估,并统计术后跟距关节融合率。结果 26例患者均获得随访,随访时间10~32个月,平均19.5个月,A组手术所用时间及术中出血量均少于B组;在术后并发症方面,A组出现1例跟骨处螺钉尾帽处疼痛,B组2例出现切口皮肤皮瓣感染或坏死,2例出现腓骨肌腱卡压症状,1例出现晚期足外翻畸形致胫神经受压,出现足内侧疼痛;术后足踝功能评分A组优8例,良3例;B组优7例,良4例;术后两组患者末次影像学随访显示均得到有效骨性融合,无明显差异。结论应用微创经皮空心螺钉内固定术行跟距关节融合术治疗跟距关节炎,可重建距下关节稳定性,可获得良好的复位及固定,与传统术式相比,在保证得到有效的骨性融合前提下,具有手术耗时少、出血少、术后并发症少等优点。

跟骨截骨下移延长术治疗陈旧性跟骨骨折

作者应用跟骨截骨下移延长术治疗陈旧性跟骨骨折38例39足,其中34例35足经1～7年随访,91.4%的病人矫形效果和功能恢复优良.手术有效地消除了思足疼痛和跟骨变宽、变短.平足及跟外(内)翻畸形.本文讨论了陈旧性跟骨骨折的临床分类,介绍了手术方法和注意事项.认为本手术能恢复患足的生物力学结构,术后康复时间短,优于距下或三关节融合术.     

应用三相截骨和距跟关节融合术治疗陈旧性跟骨骨折

对于陈旧性跟骨骨折常遗留下的后足畸形和距跟关节创伤性关节炎，以往的手术多采用跟骨截骨等方法，以恢复足弓及Ｂｈｌｅｒ角，但后足的疼痛和功能改善大多数不满意。自１９８７～１９９５年期间，作者应用三相截骨和距跟关节融合术治疗了陈旧性跟骨骨折１７例（１９足，均为波及后关节面骨折），经矫正畸形和距跟关节融合后使跟骨尽可能恢复了生物力学结构，达到了最大程度上的功能改善。经术后１～８年，平均４年随访，８９．４％患者获得了满意的疗效。作者认为：应用三相截骨和距跟关节融合术治疗陈旧性跟骨骨折，皆依据陈旧性跟骨骨折遗留下的病残而施行的矫形手术。在治疗前，应充分加以考虑，拟定治疗方案。     

跗骨间骨桥临床诊断与治疗研究进展

目的总结跗骨间骨桥临床诊断与治疗研究进展。方法查阅近年关于跗骨间骨桥的诊断及治疗相关文献,进行综述分析。结果跗骨间骨桥是足部跗骨间桥接组织,常见类型为跟距骨桥和跟舟骨桥。跟舟骨桥在后足斜位X线片即可确诊,多数跟距骨桥需CT扫描确诊,MRI可用于软骨性和纤维组织性骨桥的诊断。石膏固定对于有症状患者是首选治疗方法;对于治疗失败未发生退行性变患者,切除骨桥可取得良好治疗效果。单纯距下关节融合可用于治疗跟距骨桥切除失败的患者,对于距下关节融合失败和跟舟骨桥切除失败的患者可行三关节融合术。微创治疗应严格掌控手术适应证。结论跗骨间骨桥诊断方法较为明确,应将临床表现和影像学检查结合以提高诊出率。手术治疗指征尚存在争议,仍需基于随机对照试验的长期随访报道。

Treatment of symptomatic talocalcaneal coalition

The cases of fourteen patients who had twenty-three symptomatic talocalcaneal coalitions were reviewed at a mean of 3.9 years (range, 2.2 to 9.5 years) after treatment. Five feet in three patients became completely asymptomatic after immobilization in a cast, and four feet underwent triple arthrodesis. Fourteen feet had resection of the coalition when the symptoms were not relieved by immobilization in a cast. The indications for resection of a talocalcaneal coalition include failure of non-operative treatment, a coalition that is less than one-half of the surface area of the talocalcaneal joint, and the absence of degenerative arthritic changes in the talonavicular joint. Good results were noted in thirteen feet and satisfactory results, in ten, for all forms of treatment.     

Tarsal Coalitions in the Adult Population: Does Treatment Differ from the Adolescent?

There is a paucity of information on adult coalitions without large, well-designed outcome studies. Current recommendations are thus similar to those for adolescents. Based on the available literature, current recommendations include an initial trial of adequate nonoperative treatment in symptomatic coalitions. Unlike adolescent coalitions, nonoperative treatment may be even more effective in the adult patient as many are asymptomatic or discovered after injury. If nonoperative treatment fails, then surgical intervention is considered and tailored to the location of the coalition, existing advanced arthrosis, and any existing deformity. Similar to the adolescent, surgical treatment for adult calcaneonavicular coalitions typically involves an attempt at resection with some type of interposition. Resection can be attempted for talocalcaneal coalitions that do not present with advanced arthrosis or significant hindfoot malalignment. For those patients with advanced arthrosis, more than 50% involvement of the joint hindfoot malalignment, subtalar or triple arthrodesis is recommended. The decision between resection and arthrodesis is controversial in the adolescent population. With few outcome studies in adults, it is even more difficult to make definitive treatment recommendations; however, the indications for resection are likely even more limited. It is likely that the adult subtalar coalition that becomes symptomatic and fails nonoperative treatment will require arthrodesis for full pain relief and improvement in objective outcome measures, such as the AOFAS hindfoot score. Our treatment algorithm focuses first on a trial of nonoperative treatment of at least 3 months regardless of coalition location. After failed nonoperative treatment, calcaneonavicular coalitions are in most cases treated with excision and interpositional fat graft. For talocalcaneal coalitions, resection is offered to patients with neutral hindfoot alignment, some preservation of subtalar joint motion and no adjacent joint arthrosis. The patients are advised that the outcome after resection of talocalcaneal coalitions is less predictable than resection of calcaneonavicular coalitions. Those patients with absent subtalar motion and relatively normal hindfoot alignment are candidates for in situ fusion of the subtalar joint. For those patients with greater than 15° of valgus hindfoot malalignment on a weight-bearing hindfoot alignment view or adjacent joint arthrosis, a triple arthrodesis is recommended with or without medial displacement osteotomy of the calcaneus. Adjacent joint arthrosis may be determined by radiographs, CT scan, or preoperative MRI.

目的探讨采用关节镜下改良后踝入路切除治疗成人疼痛性跟距骨桥的疗效。方法 2015年1月-2017年12月,采用后踝高位外侧观察入路结合低位内侧操作入路切除治疗9例成人疼痛性跟距骨桥。男6例,女3例;年龄19~30岁,平均24岁。2例无明确局部外伤,7例有足踝部扭伤病史。病程6~30个月,中位病程12个月。跟距骨桥Rozansky分型:Ⅰ型5例(5足),Ⅱ型2例(2足),Ⅲ型2例(2足)。患者既往无肢体功能障碍后遗症、无肢体关节手术史。术后随访复查踝关节正侧位X线片、踝关节CT。比较手术前后疼痛视觉模拟评分(VAS)及美国矫形足踝协会(AOFAS)踝-后足评分。结果患者手术时间60~90 min,平均76 min。术后患者均获随访,随访时间12~24个月,平均18个月。术后切口均Ⅰ期愈合,无感染、皮肤坏死、下肢深静脉血栓形成、血管神经及肌腱损伤、骨桥复发等并发症发生。术后踝关节功能恢复良好,疼痛明显缓解;患者于术后3~5个月,平均3.9个月重返工作岗位。末次随访时VAS评分为(0.7±0.5)分,与术前(4.2±0.5)分比较差异有统计学意义(t=20.239,P=0.000);AOFAS踝-后足评分为(94±4)分,与术前(62±2)分比较差异有统计学意义(t=–27.424,P=0.000),末次随访时获优7例,良2例。结论后踝高位外侧观察入路结合低位内侧操作入路显露跟距骨桥更直观,操作空间更大,操作过程更灵活,术中根据特定解剖标志程序化切除跟距骨桥,操作具有可行性。     

Symptomatic talocalcaneal coalition. Its clinical significance and treatment

The clinical significance of symptomatic talocalcaneal coalition was described subjectively, objectively, and identified roentgenographically after examining 67 feet of 42 patients between 1977 and 1987. Computed tomographic examinations, conducted on 29 of 42 patients, were useful in recognizing the extent of coalition, the condition of union, and the postoperative results. Tarsal tunnel syndrome was present in 23 feet with the coalition. Thirty-one feet (24 patients) were treated conservatively and 36 feet (29 patients) surgically. Of the surgically treated feet, the coalition was excised in 33 and talocalcaneal fusion was performed in three. Follow-up examinations were performed at an average of 5.3 years (range, 2.25-11.2 years). In the excision group, the results were excellent in 24 feet, good in seven, and fair in two. The results were good in three feet treated by arthrodesis.     

Complete tendon transfer and inverse Lambrinudi arthrodesis: preliminary results of a new technique for the treatment of paralytic pes calcaneus

BACKGROUND: Paralytic pes calcaneus is commonly associated with myelomeningocele and continues to be one of the most difficult deformities to treat. The purpose of the present study is to describe and report the preliminary results of a new procedure to dynamically correct paralytic pes calcaneus. MATERIALS AND METHODS: Since 2002, the senior surgeon operated on six patients with myelomeningocele and developed a new procedure to dynamically correct paralytic pes calcaneus. This new procedure combines a complete tendon transfer (tibialis anterior and posterior, peroneus brevis and longus, and extensor digitorum and hallucis longus) to the Achilles tendon and an additive triple arthrodesis. The extent of the calcaneus deformity was evaluated by measuring the talocalcaneal angle. The mean followup was 32 months. RESULTS: Excellent results were achieved in five of the six patients with a mean age of 17.5 years. Using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scale, pain and function improved from an average of 41.6 preoperatively to 72.0 postoperatively. The deformity as assessed by the talocalcaneal angle, the calcaneal pitch, and the talometatarsal I angle improved after surgery significantly (p < 0.004). After 12 months, an additional surgery was required in two patients due to disabling drop-foot. CONCLUSION: This new surgical technique to correct paralytic pes calcaneus including complete tendon transfer and triple arthrodesis is promising. Although this is a technically demanding procedure, it provides an excellent functional result without the residual complications associated with ankle arthrodesis.     

Osseous and non-osseous coalition of the middle facet of the talocalcaneal joint.

Sixteen patients (eighteen feet) who had a coalition of the middle facet of the talocalcaneal joint had operative resection of the coalition because nonoperative treatment, such as casts, failed to relieve the symptoms. The patients were symptomatic for an average of one and a half years (range, four months to two years) before they were seen by us. The average age at the time of the operation was fourteen years (range, seven to nineteen years). Three feet had resection with no material interposed, six had resection with interposition of fat, and nine had resection with interposition of half of the tendon of the flexor hallucis longus muscle. The average length of follow-up was four years (range, two to eight years). The result was excellent for eight feet, good for eight feet, and fair for one foot; for one foot, the result was poor because the coalition recurred. Three types of coalition were identified on preoperative computed-tomography scans that correlated with the operative findings. Type I was an osseous bridging of the middle facet joint (five feet). Type II (cartilaginous coalition) was marked narrowing of the middle facet joint with cortical irregularity (three feet). In Type III (fibrous coalition), there was only slight narrowing of the middle facet joint (ten feet). The type of coalition did not influence the result. Fibrous coalitions were the most difficult to detect; bone scintigraphy was used to confirm the diagnosis when other tests were equivocal. We believe that symptomatic coalition of the middle facet of the talocalcaneal joint should be treated with resection when non-operative methods fail to relieve symptoms.     

关节外距下关节固定术治疗痉挛性双瘫扁平足临床疗效分析

目的：介绍应用关节外距下关节固定术治疗痉挛性双肢瘫患儿扁平外翻足畸形的手术指征和方法,对临床疗效及结果作出评价,并讨论其矫正机制和矫形效果。方法2011年4月至2013年6月我科采用关节外距下关节固定术技术治疗痉挛性双肢瘫患儿28例（46足）,并根据畸形的程度给予相应的软组织重建手术。术后根据美国足踝外科协会（American Orthopaedic Foot and Ankle Society, AOFAS）踝-后足功能评分,从疼痛、功能、对线三方面评价患儿临床效果,同时观察患儿足外翻的影像学指数的改变,比较前后位片距骨-第一跖骨角和距跟角,正侧位距骨-第一跖骨角（Meary角）、跟骨倾斜角和跟骨-第一跖骨角（Hibbs’角）的变化。结果所有患儿术后平均随访2年8个月,所有患儿骨性愈合并且畸形没有复发。采用AOFAS踝-后足功能评分标准评价临床结果,平均得分88分,28足优,18足良。影像学评价测定术前及术后随访时足负重前后位的距跟角、正侧位Meary角及Hibbs’角比较,差异均有统计学意义（均P<0.05）。结论关节外距下关节固定术治疗痉挛性双肢瘫患儿扁平外翻足畸形疗效确切,后足外翻术后的指数和距下关节稳定性得到明显改善。目前本研究仅为中短期的观察,还需要长期的随访观察。     

Kinematic changes in patients with double arthrodesis of the hindfoot for realignment of planovalgus deformity

Double fusion (i.e., fusion of the subtalar and talonavicular joint) represents a modification of triple arthrodesis preserving integrity of the calcaneocuboidal joint. Our aims were (1) to evaluate dynamic plantar pressure distribution in patients undergoing double arthrodesis, (2) to obtain a comparison of kinematic changes to healthy feet, (3) to evaluate the influence of radiographic alignment, and (4) to assess functional outcome. Sixteen feet (14 patients) treated by double fusion due to fixed planovalgus deformity were included. Dynamic plantar pressure distribution was assessed using a capacitive pressure platform. Results were compared with a demographically matched control group. Clinical assessment included the American Orthopaedic Foot and Ankle Society (AOFAS) score and radiographic assessment included measurement of talometatarsal, calcaneal pitch, and talocalcaneal (TC) angle on lateral radiographs. Significant differences in plantar pressure distribution were found for maximum force of the hindfoot, midfoot, and big toe region: While the hindfoot and hallux represented decreased load in the double arthrodesis patients, load increased in the midfoot region compared with healthy controls. The lateral talus‐first metatarsal‐angle increased from ?16.3° to ?8.2°, and the TC angle decreased from 41.3° to 35.8° (p < 0.05). The pre‐ and post‐operative AOFAS score increased from 37 points (SD, 16.3) to 70 points (SD, 16.7). These results revealed that double arthrodesis represents a reliable method for correction of planovalgus deformity. Compared with healthy feet, force transmission of the midfoot is increased whereas push‐off force decreases. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

成人跟距联合术后功能的影响因素分析

背景：成人跟距联合手术治疗方案临床报道较少,术后的功能评估尚不明确。目的：探讨影响成人跟距联合术后功能的相关因素,从而决定更好的手术方案。方法：回顾性研究2011年1月至2013年7月我院收治且获得完整随访资料的24例行跟距联合术的患者资料,男13例,女11例;年龄19~53岁,平均31.5岁。根据术前症状及影像学检查决定手术方案。记录患者年龄、跟距联合分型、跗骨联合的大小、有无距下骨关节炎、后足的外翻角度。应用美国足踝医师协会踝-后足评分表（AOFAS-AH）和踝关节Karlsson-Peterson评分对患者术后的踝关节功能进行评估,并对上述因素进行相关性分析。结果：24例患者获得平均19.5个月的随访（4~33个月）。单纯联合切除术19例,其中4例进行三角韧带修补,1例行外侧韧带重建,1例行跟骨截骨内移术。距下关节融合术5例,其中3例患者仍有疼痛症状。术后的AOFAS评分和Karlsson-Peterson评分均明显改善。经Logistic回归分析,距下关节骨关节炎是术后踝关节功能的影响因素,而跟距联合分型、跗骨联合的大小和后足的外翻角度无明显相关性。结论：距下关节骨关节炎影响跟距联合患者术后的踝关节功能评分,即使行距下关节融合术,在一定程度上也影响患者术后踝关节功能。
