Scapular osteochondromas treated with surgical excision.

A retrospective review was performed of all osteochondroma excisions at our institution from 1994 to 2007. Postoperative functional assessment was completed with use of the Disabilities of the Arm, Shoulder and Hand (DASH) survey and a self-report questionnaire. Eight osteochondromas were excised at a mean patient age of 21.63 years. Presenting reports included pain, mass, pseudowinging, and snapping of the scapula. Physical examination identified pseudowinging, palpable mass, and pain with shoulder motion. The lesions arose from the ventral surface of the scapula in 5 patients, the dorsal surface in 2, and the inferior acromion in 1. The resected specimen averaged 10.8cm(3). A reactive bursa was found and resected in 4 patients. At mean of 4.17 years postresection, no signs of recurrence were found in 7 patients (88%). The single patient with a recurrence had undergone 2 additional surgical procedures. Six patients (75%) reported no/mild pain with routine and strenuous activities. One patient reported moderate and 1 patient reported moderate/severe pain with routine and strenuous activities. Four patients reported post-resection function as excellent, 2 as good, 1 as average/good, and 1 as average/poor. Six patients (75%) reported feeling very satisfied with the results, 1 reported feeling satisfied, and 1 reported feeling unsatisfied. The average DASH score was 11.7 (range, 0.00-46.67). No winging or pseudowinging was identified in those available for examination, and no difference was identified in range of motion comparing the operative to the nonoperative upper extremity. Near normal functional outcomes can be expected following excision of scapular osteochondromas.

Assessment of femoral anteversion in children with cerebral palsy: accuracy of the trochanteric prominence angle test.

Clinical assessment of femoral anteversion (FA) in children with cerebral palsy (CP) is frequently determined by the trochanteric prominence angle test (TPAT). Limited three-dimensional volumetric imaging by axial tomography of the femur was performed before surgery for 35 hips in 20 children with CP. The TPAT was performed before the imaging study for 31 hips in 18 children. The TPAT angle was within 10 degrees of the FA as determined from the computed tomography scans (Murphy technique) for 17 femurs (55%). The most prominent portion of the greater trochanter was located anterior to the femoral neck axis (mean 27 degrees, range 0 degrees-52 degrees) on the three-dimensional images in 34 of 35 hips. A simulated TPAT, measured from the imaging studies, consistently underestimated the FA as determined by the Murphy technique (mean 10 degrees, range 0 degrees-18 degrees). Accurate clinical assessment of FA by the TPAT in children with CP presumes that the prominence of the greater trochanter lies perpendicular to the axis of the femoral neck. Three-dimensional imaging showed the prominence to be anterior, to a variable degree, to the femoral neck axis, which in addition to clinical factors such as obesity compromises the accuracy of this clinical maneuver.
