Transmetatarsal amputation TMA involves the surgical removal of the distal portion of metatarsals in the foot. It aims to maintain weight-bearing and independent ambulation while eliminating the risk of spreading soft tissue infection or gangrene. This study aimed to explore the risk factors and surgical outcomes of TMA in patients with diabetes at an academic tertiary referral center in Jordan. Patient characteristics along with clinical and laboratory findings were analyzed retrospectively. The study cohort comprised 81 patients with diabetes who underwent TMA. Of these, 41 Most of the patients were insulin-dependent

The prevalence of diabetes mellitus in the U. But while transmetatarsal amputations TMA are a common type of minor amputation due to diabetes for limb salvage, the long-term durability of this procedure remains largely unknown. In their retrospective study, Tokarski et al. Tokarski et al. Patients were required to have had a successful transmetatarsal amputation, defined by the authors as having demonstrated clinical healing in the one-year post-surgery. In all cases, the TMA had been performed due to a diabetic foot ulcer infection. Here are some of their key findings on timing of healing and re-ulceration:. They also found the below factors significant in assessing durability of TMAs:. Overall, however, they consider a successful transmetatarsal amputation to be a durable procedure for amputation due to diabetes and diabetic limb salvage but note that with high re-ulceration rates and likelihood of a more proximal amputation, surgeons should be aware that patients can be at risk. The study authors recommend lifelong follow-up, revision surgery and tendon balancing as needed. While Tokarski et al. In their retrospective analysis published in the Journal of Surgical Research , Kantar et al. The rate of wound complications was found to be They found that patients who had a significantly longer operative time were more likely to develop post-operative wound complications.

You may need a TMA if you have poor blood flow to your foot or a severe infection. A toe amputation is a surgery to remove one or more toes. When you leave the hospital, your incision is most often closed with stitches or staples.

The tarsometatarsal joints Latin: articulationes tarsometatarsales are three synovial plane type joints located in the foot. These articulations are formed between the most distally located tarsal bones cuboid , lateral cuneiform , intermediate cuneiform and medial cuneiform and the metatarsal bones. The set of tarsometatarsal joints is also known as the Lisfranc's joint , named after the French surgeon Jacques Lisfranc de St. The Lisfran'c joint line is located between the tarsals and metatarsals, and it permits the mid-foot amputation. The tarsometatarsal joints consist of three isolated joints that involve the cuboid bone , three cuneiform bones and metatarsal bones.

In a thorough review of the literature on the transmetatarsal amputation in patients with diabetes, these authors discuss keys to proper patient selection, essential biomechanical aspects of the procedure, when adjunctive procedures can have an impact and tips on post-op shoe gear. Non-traumatic lower extremity amputation LEA in the United States is attributed to diabetes more than any other disease with an overall incidence of per , person-years. This number will likely continue to climb as the number of patients afflicted with diabetes increases and life expectancy continues to rise. Limb preservation in the diabetic population remains challenging and is most effective utilizing a multidisciplinary approach. Primary objectives include maximizing function; minimizing the risk of tissue breakdown and the need for a more proximal amputation; and avoiding the morbidity and mortality associated with major limb amputation and the need for intensive rehabilitation. When surgeons perform the transmetatarsal amputation TMA correctly and in combination with adjunctive procedures when necessary, the TMA is a valuable surgery in the limb salvage effort, and preferred over a below- or above-knee amputation when functionally and physiologically reasonable with authors reporting success rates of over 90 percent. Researchers have shown that oxygen consumption increases up to percent of normal during ambulation in patients with major limb amputations. Furthermore, day mortality rates for below- and above-knee amputations are much higher than those for TMAs with authors reporting rates as high as 6. These risk factors may be neurological, vascular or biomechanical in nature. It is well known that peripheral sensory neuropathy and peripheral vascular disease PVD are independent risk factors for lower extremity amputation in patients with diabetes.
