Objective
To evaluate the results of the open palm technique for the treatment of Dupuytren's disease.
Method
The authors used the technique described by McCash. Twelve patients (13 hands) were surgically treated, between october 2002 and september 2011.
Results
The wounds healed in a medium of 25 days (variation of 17 to 30 days). There were no complications, such as infection, haematoma formation, skin necrosis, residual edema.
Conclusion
The open palm technique remains a safe alternative for the treatment of Dupuytren's disease, with satisfactory results and low risk of complications.
Objective: To evaluate the knees of individuals with renal failure who are on hemodialysis, using magnetic resonance imaging (MRI), comparing them with those of a group of individuals with normal renal function. Materials and Methods: This was a cross-sectional, observational, controlled study conducted between August 2018 and February 2020. The cases consisted of 15 patients who had been on hemodialysis for ≥ 5 years and did not have a quadriceps tendon rupture. The controls consisted of 15 individuals with normal renal function who were matched (1:1) to the cases for sex, age, and physical activity level. The subjects in both groups underwent MRI of the right knee only. Results: The mean ages of the cases and controls were 50 ± 15 years and 49 ± 14 years, respectively. The median time on hemodialysis was 11 years (range, 10-14 years). Serum levels of parathyroid hormone, ferritin, alkaline phosphatase, phosphorus, and creatinine were higher among the cases than among the controls, whereas serum albumin and hemoglobin were lower (p < 0.05 for all). The MRI study showed a hyperintense signal in the quadriceps tendon in 11 of the cases and in three of the controls (p = 0.009). Knee joint effusion was observed in nine of the cases and in three of the controls (p < 0.05). The thickness, length, and width of the tendon did not differ between the groups. A hyperintense signal in the tendon was not associated with the time on hemodialysis; nor with the levels of intact parathyroid hormone, hemoglobin, or alkaline phosphatase. Conclusion: Patients on chronic hemodialysis, even those without a tendon rupture, show a hyperintense signal in the quadriceps tendon on MRI.
Quadriceps tendon tears are uncommon injuries often associated with chronic diseases, including end-stage renal disease (ESRD). The role of secondary hyperparathyroidism as a predisposing factor for tendon tears in this group of patients is well documented, and the weakening of the tendon-bone junction is part of this context. The treatment of choice for quadriceps tendon ruptures in patients with ESRD is surgery, which should be performed as soon as possible. There are several surgical techniques to be used, but the lack of comparative studies does not allow us to conclude which one is the best option. More recent publications have preferred the association of techniques, with emphasis on the use of autologous tendon grafts as a reinforcement tool, which is the author’s procedure of choice. Recent studies reported the use of biological agents to stimulate healing and allografts, but the information seems preliminary to be routinely recommended.
