  • CLINICAL ANALYSIS OF DIAGNOSIS AND TREATMENT OF ACRAL GLOMUS TUMOR

    ObjectiveTo summarize the characteristics, diagnosis, and treatment of acral glomus tumor in order to improve the level of diagnosis and treatment. MethodsThe clinical data from 70 cases of acral glomus tumor treated between June 2004 and October 2013 were analyzed retrospectively. There were 11 males and 59 females with an average age of 41 years (range, 18-67 years). The disease duration ranged from 4 months to 30 years, with a median duration of 5 years. Sixty-nine cases had solitary tumors and only 1 patient had more than 1 lesion. The tumors were located on the finger in 66 patients (67 fingers) and the toe in 4 patients (4 toes); among them, the subungual glomus tumor happened in 44 patients (44 fingers and 1 toe). All patients suffered from paroxysmal pain and pinpoint pain with positive Love's pin test, and 29 patients (28 fingers and 1 toe) had positive cold sensitivity. Fifty-two patients (48 fingers and 4 toes) were found to have glomus tumor according to the high-frequency color doppler ultrasonography. X-ray films revealed depression on the phalanx in 16 patients (14 fingers and 2 toes). ResultsNo patient suffered from delayed incision healing, and infection after surgical treatment. The follow-up time was from 1 month to 9 years and 2 months with a median follow-up time of 20 months. The clinical symptoms disappeared after surgery with no dysfunction or recurrence. ConclusionThe diagnosis of acral glomus tumor is easy because of the typical symptoms:paroxysmal pain, pinpoint pain, and cold sensitivity. High-frequency color doppler ultrasonography may play an important role in the preoperative assessment of glomus tumors with accurate localization.

  • MINIMALLY INVASIVE FIXATION UNDER COMPUTER-ASSISTED NAVIGATION FOR TREATMENT OF PERIACETABULAR FRACTURES, ANTERIOR AND POSTERIOR PELVIC RING FRACTURES

    ObjectiveTo investigate the application and technical essentials of computer-assisted navigation in the surgical management of periacetabular fractures and pelvic fractures. MethodsBetween May 2010 and May 2011, 39 patients with periacetabular or anterior and posterior pelvic ring fractures were treated by minimally invasive fixation under computer-assisted navigation and were followed up more than 2 years, and the clinical data were analyzed retrospectively. There were 21 males and 18 females, aged 15-64 years (mean, 36 years). Fractures were caused by traffic accident in 23 cases, crush injury in 6 cases, and falling from height in 10 cases. Of them, 6 cases had acetabular fractures; 6 cases had femoral neck fractures; 18 cases had dislocation of sacroiliac joint; and 15 cases had anterior pelvic ring injuries. All patients were treated with closed or limited open reduction and screw fixations assisted with navigation. ResultsEighty-nine screws were inserted during operation, including 8 in the acetabulum, 18 in the neck of the femur, 33 in the sacroiliac joint, and 30 in the symphysis pubis and pubic rami. The mean time of screw implanted was 20 minutes (range, 11-38 minutes), and the average blood loss volume was 20 mL (range, 10-50 mL). The postoperative pelvic X-ray and three dimensional CT scan showed good reduction of fractures and good position of the screws. No incision infection, neurovascular injury, or implant failure occurred. All patients were followed up 27-33 months with an average of 29.6 months. The patients could walk with full weight loading at 6-12 weeks after operation (mean, 8 weeks); at last follow-up, the patients could walk on the flat ground, stand with one leg, and squat down, and they recovered well enough to do their job and to live a normal life. ConclusionMinimally invasive fixation under computer-assisted navigation may be an excellent method to treat some specific types of periacetabular and anterior and posterior pelvic ring fractures because it has the advantages of less trauma and blood loss, lower complication incidence, and faster recovery.
