RESUMO

PURPOSE: Fractures of trapezium are uncommon carpal bone fractures and often unrecognized lesions. We investigated about operative treatment of trapezium fracture. MATERIALS AND METHODS: Seven patients with fractures of trapezium were evaluated after surgical treatment with a mean follow up time of 18 months (12 months~3 years). Functional assessment (pain, limitation in activities of daily living, satisfaction), physical examination (range of motion, grip strength), and radiographic evaluation were performed. Traumatic arthritis and carpometacarpal joint subluxation were confirmed by radiograph. RESULTS: During study period, 122 cases were carpal bone fractures, and seven of 122 cases were fractures of trapezium. All cases were intra-articular fractures of trapezium. 1st carpometacarpal joint dislocation at 4 patients, Bennett's fracture at 1 patient, hamate hook fracture at 1 patient, and base of 4th proximal phalanx fracture at 1 patient were associated with fracture of trapezium. Open reduction and internal fixation were performed at 6 cases and 1st carpometacarpal joint arthrodesis was performed at 1 case because of neglected fracture. One of 6 cases which were performed to open reduction and internal fixation was reoperated to external fixation due to reduction loss. Clinically 6 patients revealed good results. one of 7 patients experienced limitation of thumb opposition. CONCLUSION: Based on the good results obtained with surgical intervention, we advocated open reduction and internal fixation for fractures with intraarticular depressed more than 2 mm or combined with Bennett's fracture or carpometacarpal subluxation.

RESUMO

STUDY DESIGN: Retrospective study. PURPOSE: First, to examine the association between bone mineral density (BMD) and the halo phenomenon, and second, to investigate risk factors predisposing to the halo phenomenon and its correlation with clinical outcomes. OVERVIEW OF LITERATURE: The few in vivo studies regarding the relationship between pedicle screw stability and BMD have shown conflicting results. METHODS: Forty-four female patients who underwent spine fusion surgery due to spinal stenosis were included in this study. The halo phenomenon and fusion state were evaluated through plain radiographs performed immediately after surgery and through the final outpatient follow-up examination. BMD, osteoarthritis grade in the hip and knee joints, and surgical outcome were also evaluated. RESULTS: BMD was not related to the halo phenomenon, but age, absence of osteoarthritis in the knee, and non-union state were found to be significant risk factors for the halo phenomenon. However, the radiological halo phenomenon did not correlate with clinical outcome (visual analogue scale for back pain and leg pain). CONCLUSIONS: The halo phenomenon is a simple phenomenon that can develop during follow-up after pedicle screw fixation. It does not influence clinical outcomes, and thus it is thought that hydroxyapatite coating screws, expandable screws, cement augmentation, and additional surgeries are not required, if their purpose is to prevent the halo phenomenon.
