Lower Limb Replants Dr Lip Teh History • William Balfour (1814) - fingertip reattachment • Thomas Hunter(1815) – thumb reattachment • William Halstead and Alexis Carrel (1880s) canine replantation experiments limbs – Nobel Prize in 1912(Carrell) for his work on vascular anastomoses and renal transplantation. • Ronald Malt(1962) first successful replantation of an entire limb – 12-year-old boy severed arm. • Komatsu/Tamai (1968) – first microscopic digit replantation Lower limb amputations • Most commonly due to – High speed MVA – Train accidents – Occupational accidents Lower limb replants • Surgical options: – Amputation • Fillet /composite flaps (Jupiter PRS 1982) • Flap banking (Godina PRS 1986) – Replantation – Limb banking and secondary replantation (Hidalgo 1987) Lower limb replants • decision not to replant is much more compelling in lower limb – function of the lower extremity can be replaced by a prosthesis – the injury is more severe/multitrauma – the unpredictable recovery of repaired nerves – severe general complications or local complications such as necrosis, infections, nonunions – the need for secondary lengthening, or other reconstructive procedures – the economic cost to the patient and community is less. Lower limb replants • Indications – Young age – Bilateral amputations – Clean amputations • MESS – Energy, Shock, Ischaemia, Age • Short ischaemic time Lower limb replants • Goals – Functional – Sensate – Pain free – Stable – Aesthetically pleasing Lower limb replants • Bone shortening is not a contraindication • Crossover replantation – bilateral total or subtotal amputations, when anatomic replantation is not possible. Amputate or Replant • Data from limb salvage in lower limb injuries • J Trauma. 2002 Apr;52(4):641-9. – Factors influencing the decision to amputate or reconstruct after high-energy lower extremity trauma. MacKenzie EJ, Bosse MJ, Kellam JF, et al – 527 patients with Gustilo type IIIB and IIIC tibial fractures, dysvascular limbs resulting from trauma, type IIIB ankle fractures, or severe open midfoot or hindfoot injuries. – CONCLUSION: Soft tissue injury severity has the greatest impact on decision making regarding limb salvage versus amputation. Amputate or Replant • • J Trauma. 1997 Sep;43(3):480-5. The functional outcome of lower-extremity fractures with vascular injury. Lin CH, Wei FC, Levin LS, Su JI, Yeh WL – – – – 36 revasularisations for IIIC Fractures overall secondary amputation rate 25% and the salvage rate 75% 80% required secondary coverage procedures that included 12 free flap transfers Every patient needed subsequent reconstructive surgery to achieve an acceptable functional result. In this series, – MESS was able to predict the secondary amputation rate and the functional result. – salvaged limbs with MESS < or = 9 exhibited a significant difference in achieving adequate function compared with limbs with MESS > 9. – onclusions are (1) more severely injured limbs have poor functional results, (2) every patient needs subsequent reconstructive surgery, and (3) the MESS may be helpful in decision-making. Amputate or Replant • Surgery. 1990 Oct;108(4):660-4 • Combined orthopedic and vascular injury in the lower extremities: indications for amputation. Odland MD, Gisbert VL, Gustilo RB, Ney AL, Blake DP, Bubrick MP. • 25 patients with vascular repairs; • The risk factors associated with amputation – shock on admission (10 of 19 patients [p less than 0.02]) – a crushed extremity (10 of 18 patients [p less than 0.01]). • The overall amputation rate 35.2%. Amputate or Replant • J Reconstr Microsurg. 2004 Nov;20(8):621-9. • Can indications for lower limb replantation and revascularization be expanded with simultaneous free-flap transfer for limb salvage? Akoz T, Yildirim S, Akan M, Gideroglu K, Avci G, Cakir B. • replanted or revascularized five lower limbs all had free tissue transfers • 1 latissimus dorsi muscle, 2 TRAM, and 2 anterolateral thigh flap. • 1 total failure – necrosis/infection • Indications for lower limb salvage may be enhanced and successful results may be obtained in one stage, with low complication rates and shorter hospital stays. Outcomes • Microsurgery. 1991;12(3):221-31 • Major limb replantation in children. Daigle JP, Kleinert JM. – 7 lower extremity replant – 87% of patients had a sensory recovery of more than S2+ Outcomes • J Reconstr Microsurg. 1995 Mar;11(2):89-92. • A 17-year follow-up of replantation of a completely amputated leg in a child: case report. Masuda K, Usui M, Ishii S. – – – – – – 4 year old lower leg replant maintained good cosmesis and function foot size on the affected side was 1.5 cm smaller leg length was 1.2 cm shorter than on the normal side half-standard strength of the evertors and of the plantar flexors replantation in a growing child apparently has adverse influences on skeletal growth and muscle strength around the ankle joint. Outcomes • Ann Plast Surg. 1982 Apr;8(4):305-9 Lower extremity replantation-two and a halfyear follow-up. Mamakos MS. – 11 year old above knee level – regained protective sensation to her foot. – fully ambulatory and uses a brace to stabilize her ankle – growth of the severed extremity ( 10 cm discrepancy to 5.5 cm). Outcomes • J Bone Joint Surg Am. 1990 Oct;72(9):1370-3. • Replantation of the distal part of the leg. Usui M, Kimura T, Yamazaki J. • five legs replants. • >2 year followup (average: six years). • Difficulties in squat and run because of joint contractures, muscle weakness, or deformities of the foot. • None had significant pain or any intolerance to cold, and all were satisfied with the results. Outcomes • J Bone Joint Surg Br. 2003 May;85(4):554-8. • Orthotopic and heterotopic lower leg reimplantation. Evaluation of seven patients. • Daigeler A, Fansa H, Schneider W. • five patients (orthotopic), two (heterotopic) • • • • assessed cutaneous sensation, mobility, pain, cosmetic result. Functional outcome, patient satisfaction - good, Mobility, stability, and psychological state - satisfactory. Patients with heterotopic reimplantations preferred the replanted leg to a prosthesis. • Asensate foot not a contraindication • Improves the patient's quality of life. Conclusion • Lower limb replant – Should be tried in • Children • Bilateral lower limb amputations – Compared to amputation, expect • prolonged hospital stay • delays mobilisation • secondary procedures. – Amputation with severe soft tissue injuries or other systemic injuries A world’s first? • Herald Sun 29 Mar 05: Prof Wayne Morrison, director of the Bernard O'Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne's St Vincent's Hospital, said he believed the operation was a world first. "We have had some cases of both legs, or a foot and a leg taken off, but we haven't had three limbs," Prof Morrison said. "To have three all combined, I think it must be certainly a first in Australia and I would think a first in the world." • Injury. 1997 Jan;28(1):73-6 – Replantation of four severed limbs in one patient.
