This retrospective study reviewed 80 consecutive patients (mean age 62 years; range 21-91 years) who underwent 91 transmetatarsal amputations (TMAs) between 1995 and 2003. The mean follow-up was 12 +/- 1.36 months. Sixty-two TMAs healed initially (group 1), whereas 29 TMAs did not heal by 3 months (group 2). At the final examination, in groups 1 and 2, 63 of 91 (69%) limbs were healed. Of the 28 limbs that did not heal, 25 of 28 (89%) required further proximal amputation. Initial healing correlated significantly with the ability to ambulate (p < .0001) and overall limb salvage (p < .0001). In group 1, 20 of 27 (74%) limbs that were revascularized healed (p = .0336). Nonhealing amputations were associated with end-stage renal disease (13 of 19; 68%) (p = .0209) and leukocytosis (13 of 19; 68%) (p = .0052).

Free fillet flap: Outcomes in emergency microsurgical reconstruction of upper and lower limb.

Introduction: Despite its infrequency, 'spare-part surgery' represents a reconstructive strategy that uses segments of amputated limbs as donor tissue to preserve function in other injured anatomical regions. The purpose of this study was to review our 14-year experience in emergency microsurgical reconstruction of traumatised limbs using free fillet flaps obtained from non-salvageable amputated parts.
Materials And Methods: A retrospective observational study was conducted on patients who underwent urgent free fillet flap transfer for upper or lower limb reconstruction between 2007 and 2021.

Introduction: Veterans in the US have higher rates of lower extremity amputation (LEA) compared to the general population and these rates have increased between 2008 and 2018. There is limited data which directly evaluate the potential underlying comorbidities associated with LEA in the veterans' population especially with the most recent data. Such information is critical to help inform clinical management strategies to reduce the risk of amputations among our veterans.

Background: Acrocyanosis is characterised by persistent bluish discolouration of the extremities, resulting from reduced peripheral blood flow leading to increased oxygen extraction. The aetiology can be divided into primary and secondary causes. While primary acrocyanosis is generally painless and has a benign course, secondary causes may lead to complications.

Case: An overall healthy 48-year-old man suffered a left foot mangled crush injury resulting in a post-transmetatarsal amputation and subsequently developing a painful neuroma on the plantar surface of the foot. To avoid the zone of injury, targeted muscle reinnervation was used to treat the neuroma by coapting the tibial nerve to the motor point of the flexor hallucis longus (FHL) muscle. At 1-year follow-up, the patient reported no pain at rest, returned to work, and could ambulate with an orthosis for 30 minutes.

Article Synopsis
- The study investigates the effectiveness of a new synthetic electrospun fiber matrix for treating high-risk wounds in patients treated between January 2021 and December 2022.
- Out of 21 patients, 19 underwent analysis, with a mean age of 63.58 years and various wound causes, including trauma, surgical complications, and infections.
- Results showed that 89.5% of patients achieved their treatment goals, supporting the idea that this synthetic matrix is well-tolerated and effective for diverse complex wounds, warranting further research in controlled studies.
