Causes of Residual Pain after Open Excision of Wrist Ganglion / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to verify the relationship between the residual pain and preoperative carpal instability, as well as the generalized laxity after open excision of wrist ganglion. MATERIALS AND METHODS: Sixty-four patients, who received open excision of wrist ganglion, were retrospectively enrolled. The relationships between residual pain (visual analogue scale, VAS) and postoperative function (quick disabilities of the arm, shoulder and hand, quick-DASH), between residual pain and preoperative carpal instability, as well as generalized laxity were evaluated. The carpal instability was assessed from radiologic carpal instability (dorsal intercalated segment instability and volar intercalated segment instability) and Watson scaphoid shift test. The generalized laxity was assessed by the Beighton hypermobility score. RESULTS: Pain VAS and quick-DASH were significantly improved postoperatively. There was a significant difference in postoperative residual pain between those with (n=6) and without carpal instability (n=58) (+: 2.50±1.76 vs. −: 1.18±1.24; p=0.022), but there was no correlation between carpal instability and postoperative quick-DASH. Both postoperative residual pain and quick-DASH had no correlation with generalized laxity (n=18). CONCLUSION: Patients with preoperative carpal instability had greater residual pain after excision of wrist ganglion than those without.

Is osteoporosis a risk factor for ankle fracture?: Comparison of bone mineral density between ankle fracture and control groups

OBJECTIVES: There remains controversy over osteoporotic feature of the ankle. Therefore, we investigated the possibility of the existence of a relationship between axial bone mineral density (BMD) in patients with ankle fracture group with that of the normal population in Korea under control of other confounding factors such as body mass index (BMI). METHODS: This study retrospectively reviewed medical records of patients who were treated in our institution from 2005 to 2015. A comparative analysis was carried out between 116 patients with ankle fracture (ankle fracture group) and 113 patients admitted with other orthopedic reasons (control group). Sex, age, energy level of trauma, and BMI were analyzed as variables affecting axial BMD. RESULTS: Age and sex of ankle fracture group were not different from them of control group (P = 0.968 and P = 0.870, respectively). BMI of ankle fracture group was higher than that of control (P = 0.029). The other variables showed no differences between the 2 groups. The energy level of trauma in ankle fracture group was related to only BMI (P = 0.013). CONCLUSIONS: Axial BMD of ankle fracture patients showed no difference from that of a control group in Korean population. The occurrence of ankle fracture is affected by only BMI rather than axial BMD. Evaluation of osteoporosis for patients with ankle fracture should be considered separately.
