Core technology: microtubular anastomosis, minimally invasive operation technology; Tian Heng, Second Hospital of Jilin University, Hand, Foot and Extremity Repair and Reconstruction Surgery Center Advantageous specialties: fine repair of tendon vascular nerve, repair of skin, soft tissue, bone and muscle defects; Concept orientation: trauma coverage, functional guarantee, focus on appearance Hand and foot trauma and limb combined with vascular nerve tendon injury (including limb limb dissection, finger and toe dissection, elbow and wrist Hand and foot fracture, skin and soft tissue avulsion, limb fracture with vascular nerve tendon injury, soft tissue defect, bone defect – Phase I reconstruction of blood supply, repair of tendon neurovascular defect or professional judgment treatment to provide guarantee for Phase II surgical repair and reconstruction) 1, replantation of severed tissue block (including scalp, nose, ear, lip, tongue, penis, (including scalp, nose, ear, lip, tongue, penis, testis severed – microvascular anastomosis) 2, small duct recanalization (including lymphatic duct, celiac duct, ureter, vas deferens, ureter, arteriovenous fistula) 3, repair and reconstruction of tissue defects (including skin graft, skin flap, composite tissue flap (including tendon, muscle, periosteum, cartilage, bone), osteonecrosis bone discontinuity, hand and foot reconstruction, burns, trauma (trauma, palmar tendon membrane, Achilles tendon, finger web contracture scar release and repair, ear, nose, lip, tongue, jaw, larynx, breast, esophagus, penis reconstruction – “what is missing to fill in, how much is missing to fill in” flap repair technology is the core) 4, peripheral nerve injury and compression (including Brachial plexus, lumbosacral plexus compression, quadrilateral foramen, radial elbow carpal ulnar tunnel syndrome – manifested as limb numbness, weakness, mobility disorders, muscle atrophy, deformity, fine exploration and release and functional reconstruction) 5, limb soft tissue masses (including neuroma and syringoma, lipoma, tendon sheath cyst, tendon sheath giant cell tumor, synovial tumor, mucinous cyst melanoma, squamous carcinoma, hemangioma, hemangioblastoma, endogenous chondrosarcoma, bone malignant tumor – complete enlarged resection, reduce recurrence, while using expertise to break through the tissue defect trauma repair and functional reconstruction) 6, hand and foot congenital deformity correction and functional reconstruction (including multiple, combined, giant, short, long, lacking, oblique fingers (toes), ulnar (including multiple, combined, giant, short, long, missing, oblique fingers (toes), ulnar radial wrist, tibiofibular deficiency, girdle syndrome, shoulder, elbow, wrist and finger functional reconstruction – repair and reconstruction, excellence because of focus) 7, vascular diseases of the limbs (Raynaud’s disease, vasculitis, fascial compartment syndrome, ischemic muscle contracture, lymphoma) 8, infectious diseases (diabetic foot, ingrown nail, hand and foot and interstitial infection, heat pressure, high pressure (injection injury, osteomyelitis – a deep understanding of tissue blood supply and repair process is the guarantee of high healing rate) 9, minimally invasive treatment of wrist diseases (wrist and finger arthroscopy, closed repositioning and fixation, small incision release, closure) 10, medical treatment of hand and foot related diseases (diabetes, vasculitis, soft tissue and bone with malignant growth tendency and (malignant tumor) 11.Functional rehabilitation of upper limbs and ankles (physiotherapy, braces, nerve block analgesia)
