Shoulder hemiarthroplasty for fractures of the proximal humerus
Proximal humeral fractures were managed with primary hemiarthroplasty in 57 patients, 53 women (93%) and 4 men (7%) aged 51–87 years (mean 72.2). The mean follow-up period was 52 months (range 12–98), and the mean Constant score was 59.2 (range 38–76). Patients were very satisfied (n = 19); satisfied (n = 32) or dissatisfied with the outcome (n = 5). One patient required early revision surgery. Surgical treatment of three- and four-part fractures of the proximal humerus with hemiarthroplasty is a safe and effective approach, the outcome of which appears to be related to the quality of the anatomical reconstruction of the tuberosities

Evaluation of the reliability of a new non-invasive method for assessing the functionality and mobility of the spine
For the evaluation of the functionality and mobility of the spine, several methods have been developed. The purpose of this study was to estimate the test-retest reliability of the Spinal Mouse, a new, non-invasive, computer-assisted wireless telemetry device for the assessment of the curvatures, the mobility and the functionality of the spine. Materials and methods: the test-retest reliability was evaluated in 50 adults with back or low back pain. Twenty four parameters were studied in the sagittal and frontal plane. For the characterization of the precision, the intraclass correlation coefficient and the standard error of measurement were used. Results: in the sagittal plane, 22 of the 24 parameters showed high and good reliability, while only two fair and poor. In the frontal plane, 17 parameters showed high and good reliability, five fair and two poor. Discussion: the Spinal Mouse showed excellent test-retest reliability in the sagittal plane, while a slightly inferior performance in the frontal plane, for the evaluation of curvatures, deformation and mobility of the spine
Operative treatment of unstable injuries of the cervicothoracic junction
The authors present their experience in the operative treatment of
unstable lesions at the cervicothoracic junction. Ten patients, six men
and four women, underwent operative procedures at the cervicothoracic
junction (C7-T1) between 1990 and 1997. Six patients had sustained
fracture-dislocations, three patients had metatases and one patient had
a primary malignant lesion. All the patients had significant cervical
pain and neurologic deficit. The spinal cord and nerves were
decompressed in all cases. Posterior stabilization was accomplished
using various types of implants including hooks, wires and rods.
Anteriorly, the spine was stabilized with plates and screws. Partial or
complete vertebrectomy was performed in five cases and a titanium
cylinder or an iliac autograft replaced the vertebral body. Five
patients were submitted to a posterior operation only, and the other
five to bilateral procedures. In four of these a one-stage operation was
performed and in the last case a two-stage procedure. The anatomic and
biomechanical characteristics of the cervicothoracic junction require a
precise pre-operative analysis of the local anatomy and the selection of
the proper implants for anterior and posterior stabilization
The influence of osteoporosis in femoral fracture healing time
Aim: In order to assess the effect of osteoporosis on healing time, the files of 165 patients with femoral shaft fractures that were treated in our institution with locked-reamed intramedullary nailing were retrospectively reviewed. Patients and methods: Patients with open fractures, pathological fractures, revision surgery, severe brain injuries and prolonged ITU stay were excluded. In all patients the Singh-index score for osteoporosis and the canal bone ratio (CBR) were assigned. Sixty-six patients fulfilled the inclusion criteria. Patients were divided into two groups; group A (29 patients) consisted of patients over 65 years old with radiological evidence of osteoporosis and group B (37 patients) of patients between 18 and 40 years old with no signs of osteoporosis. Results: In all group A patients Singh score ≤4 and CBR > 0.50 were assigned, suggesting the presence of osteoporosis, whereas all group B patients were assigned with Singh score ≥5 and CBR < 0.48. Fractures of group A healed in 19.38 ± 5.9 weeks (12-30) and in group B 16.19 ± 5.07 weeks (10-28), P = 0.02. Conclusions: Fracture healing of nailed femoral diaphyseal fractures is significantly delayed in older osteoporotic patients. Further studies are required to clarify the exact impact of osteoporosis in the whole healing process. © 2008 Elsevier Ltd. All rights reserved
