OVERVIEW

Hand and microvascular surgery operates at the intersection of orthopedic surgery (bone and joint management) and plastic surgery (tissue and vascular reconstruction). The primary clinical objective is preserving or restoring upper limb motility, dexterity, sensation, and tissue viability. Microvascular techniques utilize specialized instruments and miniaturized sutures to anastomose, or re-connect, small blood vessels and nerve fascicles, often measuring less than one millimeter in diameter. Guidelines from the American Society for Surgery of the Hand (ASSH 2022) emphasize early anatomical alignment and primary vascular restoration to minimize long-term functional impairment and prevent tissue necrosis.

PROCEDURE

The patient is positioned, and regional or general anesthesia is administered. The operative site is prepped using sterile antimicrobial solutions. The surgeon performs debridement of non-viable tissues and identifies key anatomical structures under surgical loupes or operating microscopes. Bony alignment is achieved first using Kirschner wires, plates, or screws. Flexor and extensor tendons are sutured using core suture techniques. Microvascular repair follows, where damaged vessel ends are trimmed, dilated, and joined using 9-0 or 10-0 nylon sutures under high optical magnification. Micro-neurorrhaphy is performed to coapt nerve endings. Skin and soft tissue defects are closed directly or reconstructed using local flaps or free tissue transfers. Drains and protective splints are applied prior to recovery transfer.

BENEFITS

Evidence-based benefits of specialized hand and microvascular surgery include:

  • Limb and digit preservation through timely revascularization and tissue coverage.
  • Restoration of sensation via microsurgical nerve coaptation and nerve grafting techniques.
  • Prevention of permanent contractures and secondary joint stiffness through structural stabilization and early guided therapy.
  • Functional independence achieved through tendon transfers, neurotization, and joint reconstruction.
  • Reduction of chronic pain associated with neuroma formation and nerve entrapment (Higgins et al., 2019).

RECOVERY

Recovery from hand and microvascular surgery proceeds through distinct biological phases. Phase one (weeks 1–2) focuses on wound healing, microvascular perfusion monitoring, and edema control via elevate-and-immobilize protocols. Phase two (weeks 3–6) introduces controlled active-assisted range of motion under the guidance of a certified hand therapist to prevent tendon adhesions. Phase three (months 2–6) initiates progressive resistance training and sensory re-education as nerve axons regenerate into target distal tissues. Full functional maturation and maximal nerve recovery typically require twelve to twenty-four months (IFSSH 2020).

WHAT WE TREAT

Hand and microvascular surgery addresses a wide spectrum of acute traumatic, chronic degenerative, and congenital conditions, including:

  • Traumatic digital or limb amputations requiring microvascular replantation (re-attachment of severed parts).
  • Peripheral nerve injuries and compressive neuropathies, such as carpal tunnel syndrome and cubital tunnel syndrome.
  • Complex soft tissue defects necessitating free flap transfer (autologous tissue transfer with vascular reconnection).
  • Brachial plexus injuries impacting upper extremity nerve signal transmission.
  • Dupuytren contracture and other progressive palmar fascial disorders.
  • Congenital hand differences, including syndactyly (webbed digits) and polydactyly (extra digits).
  • Vascular insufficiency of the hand, including Raynaud phenomenon and ulnar artery thrombosis.
  • Fractures and dislocations of the carpals, metacarpals, and phalanges.

PREPARATION

Preoperative preparation includes a comprehensive vascular assessment using Allen tests, Doppler ultrasonography, or angiography. Pre-anesthetic screening, complete blood count, coagulation profiles, and baseline radiographs are performed. Medications affecting platelet aggregation or coagulation (such as aspirin, NSAIDs, and warfarin) are reviewed and managed per clinical protocol. Smoking and nicotine exposure must cease immediately, as nicotine induces profound microvascular vasoconstriction and significantly increases the risk of flap failure or revascularization loss. The patient receives clear oral intake instructions prior to surgery.

RISKS

Complications in hand and microvascular surgery are categorized by frequency and clinical impact. Common mild side effects include local postoperative edema, transient stiffness, surgical site pain, and minor wound breakdown. Uncommon complications involve nerve entrapment, flexor tendon adhesions requiring tenolysis, localized wound infection, and cold intolerance. Rare but serious risks include acute microvascular thrombosis leading to graft or digit loss, deep space infection (tenosynovitis or osteomyelitis), persistent complex regional pain syndrome (CRPS), and permanent loss of sensation or motor function.

JOURNEY

The clinical pathway begins with a comprehensive baseline physical examination, neurovascular mapping, and advanced diagnostic imaging. Intraoperatively, the surgical team executes bony stabilization followed by microvascular anastomosis of arteries and veins, tendon repairs, and primary nerve coaptation under high magnification. Postoperatively, patients enter a closely monitored inpatient or specialized care protocol focused on microvascular flap perfusion, anticoagulation, and edema control. Hand therapy and specialized splinting commence within days to weeks according to protocol, guiding tissue remodeling over a six- to twelve-month recovery trajectory.
