Background: This study aimed to explore the effect of haematological markers as well as patient characteristics on stump healing in patients who underwent a lower limb amputation procedure. In addition, a practical model regarding factors that affected stump healing was developed. Methods: Patients who underwent a major lower limb amputation (above knee and below knee) at the Royal Infirmary of Edinburgh from the period of 2007 to 2010 were included in this study. A prognostic model utilizing backward stepwise logistical regression was developed to measure the probability of lower limb stump healing. The relationship between the dependent and independent variables was identified using univariate and multivariate logistic regression. Results: Three variables, namely serum sodium, serum creatinine and serum high density lipid cholesterol were identified which influenced stump healing. Patients with normal serum sodium were 75% more likely to have lower limb stump healing compared to that of patients with abnormal serum sodium (odds ratio [OR] 1.756; 95% confidence interval [CI] 1.048–2.942). Patients with normal serum creatinine were 66% more likely to have their stump healed (OR 1.664; 95% CI 0.94 to 2.946). The healing rate of patients with a normal level of serum high density lipid cholesterol was 75%, in contrast to patients with an aberrant level of serum high density lipids cholesterol (OR 1.753; 95% CI 1.061 to 2.895). The effectiveness of the retrospective stump-healing model was demonstrated by the area under the ROC curve (0.612), which was supported by the Hosmer and Lemeshow goodness-of-fit test (p = 0.879). Conclusions: Serum sodium, serum high density lipid cholesterol and serum creatinine have a strong correlation with lower limb stump healing. However, serum sodium and serum high density lipid cholesterol secondary to multiple co-morbidities in this cohort group could be altered secondary to disease pathology itself.
Prediction of stump healing in lower limb amputation: A narrative review
(Mark Allen Group, 2019-12-11) Ashraff, Suhel; Siddiqui, Muhammad A.; Santos, Derek; Carline, Tom
Both types of diabetes, as well as different forms of acquired diabetes, are associated with diabetic peripheral neuropathy. Diabetic foot ulcers (DFU) is the condition most commonly related to somatic peripheral neuropathy, often leading to gangrene and limb amputation. Independent from large-vessel disease, sensory loss may result in DFU development and even amputation. The crucial part of any lower limb amputation is the stump healing process, which represents the central goal of postoperative management. Despite the importance attributed to this process, a standard set of guidelines regarding efficient healing methods is yet to be formulated. Health professionals are faced with the challenge of assessing the different risk factors and deciding which has a greater influence on the stump healing rate. There is currently an insufficient number of studies regarding factors effecting lower limb amputation. The main purpose of this review is to discuss the markers that can be helpful in the prediction of stump healing in patients who have undergone lower limb amputation.
Complications of Stump Healing Among Diabetic Population
(Society of Endocrinology and Metabolism of Turkey, 2018-06-19) Ashraff, Suhel; Siddiqui, Muhammad A.; Santos, Derek; Carline, Tom
Lower limb amputation is a major procedure performed in diabetic patients with multiple comorbidities. Almost 10% of the National Health Service budget is taken up by diabetes, with diabetes-related complications accounting for 80% of the costs. The process of wound healing is complex and involves regenerating the cellular organization and the tissue layers. Diabetics are five times more predisposed to wound infection than patients without diabetes mellitus. The amputated stump frequently becomes infected due to inadequate blood circulation, a weak immune system, and poorly controlled diabetes mellitus. Pain, stump edema, and osteomyelitis are significant complications associated with lower limb amputation wounds. A number of factors may substantiate the need for re-amputation, such as stump pain and/or phantom limb pain, delayed stump infection, the formation of symptomatic bone spurs, assessment of the skin flap designed to preserve stump length, and preparation of the stump for the prosthetic device. There are currently no reliable standards that can be referred to prior to leg amputation. The clinicians, therefore, have to rely on their judgment and investigatory parameters. The main purpose of this review is to discuss the difficulties of stump healing in the diabetic population.
