Pre-operative management • “It is not to take but to make.” • Early rehab involvement! • Although same problem everywhere, not happening or inconsistency in engaging rehab pre-op
Mortality and pre-op cardiac function in vascular amputees: an N-terminal pro-brain natriuretic peptide (NT-proBNP) pilot study Clin Rehab 2008 • Peri-op mortality in LLA is high • MI is the most common cause of post-op mortality • Cardiac function is relevant during rehab because of required increased energy expenditure
Mortality and pre-op cardiac function in vascular amputees: an N-terminal pro-brain natriuretic peptide (NT-proBNP) pilot study Clin Rehab 2008 • Obj: to determine pre-op ventricular function in vascular amps by measuring NT-proBNP and to analyse the relationship b/w NT-proBNP and 30-day post-op mortality • Prospective pilot study • 19 pxs; four died w/in 30 days after sx • In 17 of 19, levels were found to be more than 2 SDs above age-corrected reference values
Mortality and pre-op cardiac function in vascular amputees: an N-terminal pro-brain natriuretic peptide (NT-proBNP) pilot study Clin Rehab 2008 Clinical messages: • Pre-op NT-proBNP levels in vascular amputees are not statistically related to 30-day mortality and level of amputation • Pre-op NT-proBNP levels in vascular amputees are high, indicating that serious ventricular disease may be present.
Decision making in Sx • “Soft tissue is more important than bone.”
Sexuality and Amputation • Lack of research • After thorough publication database search: only 11 eligible studies found • Amputees remain to be sexual beings • Sexual activities are hindered in different ways, related to type, level, and cause of amp’n • Effects of pain and body image on libido • Erectile dysfunction; decreased lubrication
Sexuality and Amputation • Higher impact on sexual functioning in the elderly compared to younger amputees • ?effect of age vs amputation • Being married or having a steady partner as an amputee give fewer problems than being single • 13-75% are not satisfied with their sexual life, despite unchanged interest in sex
Sexuality and Amputation Conclusion • Assessment of sexual functioning should be an integral component of the periodic evaluation scheme in the Rehab team. • One or more members of the Team should be trained for that assessment.
Post-op mx • Wrong concept: • Rehab only starts after the stump has healed completely • Consider x-ray of stump • trial antiperspirant spray or roller for problematic sweaty stumps? • May need less wash (q2-3 days) of stumps during colder months?
Liners • General principle: “The liner has to be as thin as possible and as thick as necessary.” Selection should be based on individual circumstances.
Knee Disarticulation • Historical love/ hate relationship • First described in literature in 1830 • Very little data • Most national surveys: 1-3 % of all amputations
Knee disarticulation • Dr Douglas Smith’s experience • 12 year data base (1995-2008) • 1787 total amputation procedures • 950 primary • 827 secondary • 62 knee disarticulation (3.5%) • Trauma= 27 pxs • Infection= 11 pxs • Vascular dse= 10 pxs • SCI= 4 pxs
North American Experience with KD with use of a posterior myofasciocutaneous flap. Healing rate and functional results in seventy-seven patients. Bowker, et al, JBJS 2000 Nov • 80 KDs in 77 pxs • Aged b/w 19-92 (average of 64) • 31 DM; 29 PVD; 14 trauma; 2 sarcoma; 1 Ollies Dse • 5 pxs died early in post-op pd • 63 of 67 healed primarily; 7 dehisced and revised to TF level • 22 of 27 who walked pre-op successfully, used a prosthesis and walked post-op
Knee disarticulation • Non-ambulatory pxs have different concerns and goals than ambulatory pxs. • How will the px transfer? • What contractures are present? • What contractures will occur? • Consider surface area and support for sitting.
Knee disarticulation • For ambulatory pxs, KD is usually more functional than a TFA • Longer lever arm • Balanced thigh muscles • Improved suspension • End bearing • Lower proximal socket brim • Sitting comfort
Knee disarticulation • Walking velocity (Pinzur, et al, Ortho, 1992 Sep) • Slightly lower than TTAs, but significantly faster than TFAs • Function (Hagberg, et al, PO Int 1992 Dec)
TFA • Consider C-knee in the elderly population! • Provides better gait • Improved stability • Improved walking speed • Less falls
TFA • Hip flexion contracture • 1st year: try to stretch to correct or lessen degree of contracture • After 1 year: provide prosthesis which will accommodate to contracture • Not cosmetic- but more functional
TFA • Who/When to prescribe a Prosthesis? • TTA: • Patient has their own knee power • Prosthesis helps w/ transfer • Prosthesis helps with STS • TFA: • Patient has no knee power • Prosthesis has no knee power • Transfers- often easier without prosthesis • STS- prosthesis makes it more challenging
TFA • Before a TF Prosthesis is prescribed, patient must master the following vital skills: (UW guidelines) • Transfer independently (both in/out of bed, on/off toilet) • STS independently • Walk in parallel bars or walker (one leg gait), for at least 6-8 meters
TFA • Explain the vital skills and importance • Offer prosthesis when patient masters skills • Places challenge on patient and family • Avoids arguments!
A plea! • A multidisciplinary Foot Clinic • In developed countries: • Up to 4% of people w/ DM have a foot ulcer • Uses 12-15% of healthcare resources for DM • Multidisciplinary foot team has been shown to bring 49-85% reduction in amputation rates
Foot Clinic • Minimal model • Doctor • Podiatrist and/or nurse • Intermediate • Doctor (diabetes specialist, surgeon, rehab) • Podiatrist and/or nurse • orthotist
ISPO Workshop • Highly recommended • Relevant • Comprehensive, but not too overwhelming • Balanced and well-respected speakers • A Sydney venue in the future?!
Remember • We are Coaches! • We must create enthusiasm! • Positive approach to Surgery • Positive approach to early rehabilitation • Positive approach to prosthetics
