Voluntary ambulation using voluntary upper limb muscle activity and Hybrid Assistive Limb® (HAL®) in a patient with complete paraplegia due to chronic spinal cord injury: A case report

Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.

Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.

Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury.     

上肢骨肿瘤切除后的自体骨移植重建

目的探讨应用自体骨移植对上肢骨肿瘤切除后的骨缺损修复重建的效果。方法1998年8月～2004年3月，收治上肢骨肿瘤切除后的骨缺损16例。男8例，女8例。年龄7～45岁。经病理确诊，肱骨近端尤文肉瘤和骨肉瘤各1例；肱骨远端尤文肉瘤2例；桡骨远端骨巨细胞瘤8例，高分化软骨肉瘤2例，恶性纤维组织细胞瘤和骨肉瘤各1例。2例肱骨近端肿瘤行自体锁骨代肱骨；2例肱骨远端肿瘤行自体腓骨代肱骨；12例桡骨远端肿瘤中，1例行自体髂骨移植，11例行自体腓骨代桡骨进行重建。采用MSTS系统进行术后功能评价。结果2例肱骨近端自体锁骨移植患者分别随访36个月和12个月，术后保持部分肩关节前屈和后伸功能，但外展功能丧失；MSTS评分分别为23分和22分。2例肱骨远端自体腓骨移植患者分别随访4个月和6个月，肘关节功能良好，移植骨连接处已经出现骨愈合；MSTS功能评分分别为24分和19分。12例桡骨远端自体骨移植患者中11例随访6～75个月，功能良好，无明显并发症；1例髂骨植骨的桡骨远端骨巨细胞瘤术后3个月移植骨完全愈合，至今随访75个月，肿瘤无复发。MSTS功能评分18~27分，平均22．6分。结论自体骨移植在上肢骨肿瘤切除后骨缺损的重建，尤其是儿童的骨缺损重建中，是一种较好的方法。     

上胸椎骨折手术治疗方法的探讨

目的 探讨上胸椎骨折的特点及治疗。方法 15例病人按AO分型，A型2例、B型10例、C型3例。均经后路切开复位、脊髓减压、长节段内固定、取髂骨植骨融合术治疗。结果 随访18-24个月，后路长节段固定随访时无一例失败，完全瘫的患者9例中有1例神经功能改善I级．不完全瘫的5例均有Ⅲ级改善，1例无神经损伤。结论 上胸椎骨折损伤严重，后路长节段固定技术是一种合理的有效治疗方法。     

髋臼骨折合并同侧下肢骨折临床治疗分析

目的：探讨髋臼骨折合并同侧下肢骨折的创伤机制和治疗方法。方法：髋臼骨折并同侧下肢骨折14例,男9例,女5例;年龄18～65岁,平均35岁。髋臼骨折按Letournel分型,后壁伴后柱骨折11例,单纯后柱骨折3例,均行钢板内固定。伴同侧股骨转子间骨折3例,1例行起重机架外固定,2例行DHS固定;伴同侧股骨颈骨折3例,均行空心钉加压固定;伴同侧股骨干骨折6例,1例行钢板固定,余5例行带锁髓内钉固定;伴同侧胫骨平台骨折2例,行钢板内固定。结果：1例半年后死亡,余13例获得随访,随访时间18个月～5年,平均30个月。按照美国矫形外科研究院髋关节疗效评定标准,优9例,良3例,差1例。结论：髋臼骨折合并同侧下肢骨折受伤暴力大、机制复杂、合并创伤多、易漏诊,应早期明确诊断,合理内固定。     

连续埋线法重睑术的临床评价

目的 探讨连续埋线法重睑术的适应证和手术要点.方法 手术在局部麻醉下施行,从外眦向内眦沿睑板上缘作连续缝合,然后折返,外眦缝合口打结.结果 本组132例患者术后随访形成良好重睑者为121例,占92%;两侧重睑皱襞高低不一的7例,占5%;重睑消失的4例,占3%,后两者均补充埋线法或者切开法重睑术修复.结论 连续埋线法重睑术除适用于上睑皮肤较薄的年轻患者,也可扩大到中等以下程度的上睑皮肤松弛患者,以及以外侧为主的上睑臃肿者.     

The laterally extended medial hemisoleus flap for reconstruction of a tibial wound in the distal third of the leg

A soleus flap as a local reconstructive option for soft-tissue coverage of a tibial wound in the distal third of the leg has never been well recognized. In a 2-year period, seven patients underwent reconstruction of a less extensive tibial wound (4 × 3 to 10 × 4 cm) in the distal third of the leg after orthopedic trauma with the laterally extended medial hemisoleus flap. The flap was elevated with emphasis on the preservation of the most distal perforators from the posterior tibial vessels to the flap as possible while allowing adequate rotation of the flap to cover the exposed tibia and/or hardware and on the possible preservation of foot planter flexion by reconstruction of the proximal Achilles’ tendon. In this series, there was no total or partial flap loss. All patients healed their tibial wounds primarily with reliable soft-tissue coverage, evidenced fracture healing, and good cosmetic outcome during follow-up. Thus, the laterally extended medial hemisoleus flap described by the author can be a reliable option for soft-tissue coverage of a less extensive tibial wound in the distal third of the leg. It offers a more cost-effective approach for managing this unique problem and can be performed by most reconstructive surgeons without microsurgical expertise.     

The callous elbow and aging of the upper arm

The author describes his surgical approach to the problems of the aging upper arm and elbow region. Surgery at an appropriate age can prevent the progressive wrinkling of the elbow which is further aggravated by aging of the upper arm. The author's operation is aimed at correcting both portions of the arm anatomy at the same time.     

Analysis thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis in the lower extremities

Objective:To explore the effect of thrombolysis with anticoagulation treatment forearly stage of deep vein thrombosis of lower extremity.Methods:The clinical data of 10 patients at the early stage of deep vein thrombosis(DVT)in the lower extremuites treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively.Results:The thrombolytic effect was significant.After treatment,the deep veins were recanalized without regurgitation in 75.3% of the patients.The total effective rate was 100%.Only three patients had hemorrhagic complication,but none of the patients died.Conclusion:Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.
