Background: Diabetic muscle infarction (DMI) is a spontaneous necrosis of skeletal muscle of unknown etiology. The major risk factor is longstanding uncontrolled diabetes mellitus (DM). Optimal treatment for DMI is not known. The purpose of this study was to analyze the outcome of surgical treatment, physiotherapy, and bed rest in DMI.
Methods: We searched Medline from its inception to April 2013. We selected cases that provided sufficient data on recovery duration, recurrences, and non-recurrences. Baseline characteristics, including age, sex, microvascular complications, lesion size estimated on magnetic resonance imaging, type of diabetes, and duration of diabetes were assessed. The primary outcome was mean time to recovery from initial treatment and secondary outcomes were mean time to recurrence and recurrence rate.
Results: Mean time to recovery was 149 (95% confidence interval [CI] 113–186), 71 (95% CI 47–96), and 43 (95% CI 30–57) days for surgery, physiotherapy and bed rest, respectively. These figures were statistically significant only for surgery versus physiotherapy and surgery versus bed rest (P<0.01). Mean time to recurrence was 30, 107, and 297 days for surgery, physiotherapy, and bed rest, respectively. The recurrence rate was 57%, 44%, and 24% for surgery, physiotherapy, and bed rest, respectively.
Conclusion: Our results show a similar outcome for physiotherapy as compared with bed rest. It also confirms nonsurgical treatment as a better therapeutic option compared with surgical treatment.
