Single-Centre Experience Regarding the Use of Fibular Graft for Reconstruction after Resection of Grade III GCT of Distal Radius.

Background: A giant cell tumour (GCT) is a locally invasive benign tumour of bone in young adults. Treatment includes surgical resection as first-line or denosumab pharmacotherapy in inoperable patients. However, surgical resection of distal radius GCT has produced debatable functional outcomes. Here we study the use of fibular grafts for reconstruction of surgically resected GCT of the distal radius. Methods: A total of 11 patients having Grade III GCT of the distal radius were recruited for a retrospective single-centred study. Five underwent arthrodesis with fibular shaft graft and six received arthroplasty with the proximal fibula. Functional outcomes at 6 weeks, 6 and 12 months were measured by Mayo wrist score (MWS) (>51% = good) and Revised Musculoskeletal tumor society (MSTS) score (>15 = good). Results: At 6 weeks, mean MSTS score and MWS were 23.64 and 58.64% respectively, and the length of the fibular graft was a predictor for both MSTS score (p = 0.014) and MWS (p = 0.006). At 6 months, the mean MSTS and MWS were 26.36 and 76.82%, respectively. At 6 months, the surgical procedure was a predictor in MSTS score (p = 0.02) while MWS was predicted by length of graft (p = 0.02). At 12 months, MSTS score was 28.73, and MWS remained 91.82%. Length of the fibular graft was an insignificant predictor, but a significant risk factor was surgical procedure for MWS (p = 0.04) at 12 months. No variable was found significant for MSTS score. Conclusions: Resection along with reconstruction of Grade III GCT of the radius with fibular graft was found an optimal treatment option. Also, use of the fibular head grafts and shorter length grafts are predictors for better outcomes after surgery. Level of Evidence: Level IV (Therapeutic).

Association of Diabetes With Lower Back Pain: A Narrative Review.

Diabetes mellitus with its increasing prevalence is one of the four major non-communicable diseases. It is characterized by hyperglycemia, which may progress to chronic complications such as peripheral vascular disease and neuropathy. This paper highlights the pathophysiology associated with diabetes, which is restricted to not only hyperglycemia but also other comorbidities including chronic lower back pain. Diabetes is a metabolic disorder associated with hypercholesteremia, hypertriglyceridemia, and hypertension. This chain of events leads to free plasma fatty acids and a pro-inflammatory state, therefore promoting calcification of blood vessels, which may block the blood supply to vertebral discs and thereby increase vulnerability in the patients with ongoing inflammatory disease such as osteoarthritis and also causing costochondritis. Functional limitation due to increased load on the weight-bearing joints is a common mechanical complication of diabetes. Obesity in diabetes is more prevalent due to a disturbed metabolism, which is aggravated with a persistent inflammatory state. Moreover, the aim of this review is to encourage further conduction of clinical studies to explore the definite cause and potential therapy for chronic lower back pain in diabetes, thereby investigating the association of lipid metabolism and skeletal muscle atrophy leading to chronic back pain, the role of diabetic medications, and vulnerability in the female gender. Diminished physical activity and depression in diabetic patients disrupt the hypothalamic-pituitary-adrenal axis (HPA), which further contributes to lower back pain. Further clinical investigation and research in this regard will establish substantial data for the linkage between depression in diabetes and back pain. However, despite all the advancements of medical literature, the exact cause of lower back pain in diabetes is arguable. Pain impedes the health status and life quality; therefore, it is essential to maintain the quality of health in patients with diabetes by treating not only hyperglycemia but also other multifactorial causes leading to lower back pain.
