Arthrodesis of the wrist for osteoarthritis: outcome with a minimum follow-up of 4 years.

The outcome of total wrist arthrodesis was reviewed in 36 patients with osteoarthritis after a minimum follow-up of 4 years. Pain relief was not complete, and although 20 were pain free at rest, only six were pain-free during manual activity. Grip strength was 63% of the contralateral side and the DASH score remained high. Only 21 of the 34 could be re-employed. The mean time off work was 14 months. Complications were numerous and additional surgery was required in 21 patients.

[The treatment of congenital tibial pseudarthrosis].

Congenital tibial pseudarthrosis (CTP) remains one of the most challenging problems in paediatric orthopaedic surgery. With the abandonment of older grafting techniques in favor of vascularized fibular transplants or the Ilizarov method the final outcome has improved and made the prognosis for patients less cumbersome. Using the latter technique in 10 patients, a success rate of 90 % could be reached. Nevertheless, although solid healing occurs in most of the patients nowadays, this is often at the cost of multiple operations before a definite well united, equalized and normally aligned limb can be obtained.

Evaluating patients with chest pain using classification and regression trees.

We collected data on 320 patients complaining to their general practitioner of a new episode of chest pain, discomfort or oppression. Relationships were examined between initial signs and symptoms and a follow-up diagnosis after a period of 2 weeks to 2 months. The data were analysed with CART, a statistical decision theory software package. In our first run, the number of misclassifications by CART was 56%. After regrouping of the data and diagnostic categories, there were 37% misclassifications. The most discriminating variable turned out to be pain on palpation. When comparing each of five diagnostic groups to all others, we found a positive predictive value of 27% for gastrointestinal diseases, 72% for cardiovascular disorders, 69% for respiratory diseases, 58% for psychopathology and 73% for chest wall pathology. The CART methodology needs further investigation and testing before any clinical application will be possible in general practice.

Chest pain: an evaluation of the initial diagnosis made by 25 Flemish general practitioners.

Twenty-five general practitioners collected information on 318 contacts of patients with a new episode of chest pain, discomfort or tightness. A list of complaints, signs and symptoms were checked, together with the initial diagnosis, made by the GP immediately after the physical examination. The initial diagnosis was compared to a follow-up diagnosis. The gain in certainty was also compared. The GP made a correct initial diagnosis in 82% of patients. In 8% there was a clinically important difference, and seven of 17 episodes of oesophageal disease were missed. For their initial diagnosis, the GP scored 74% certain, 20% uncertain and no diagnosis in 6%. For the final diagnosis, these figures were 88%, 8% and 4%.

Outcome of two salvage procedures for posttraumatic osteoarthritis of the wrist: arthrodesis or proximal row carpectomy.

PURPOSE: to compare a motion preserving procedure of the wrist with the wrist arthrodesis, the so-called gold standard in patients with posttraumatic wristpain. DESIGN: non randomized retrospective SETTING: University Hospital--referral centre PATIENTS: we studied two groups of patients with posttraumatic wrist pain due to osteoarthritis of the radiocarpal joint: one group of 35 patients underwent a radiocarpometacarpal arthrodesis, the other group of 26 patients a proximal row carpectomy (PRC). There were no significant differences in age and gender or hand dominance distribution. INTERVENTION: proximal row carpectomy versus radiocarpal arthrodesis. OUTCOME MEASUREMENTS: DASH (disability of arm, shoulder and hand) gripping force, return to activity, complications and reintervention frequence. RESULTS: Disability (DASH score) and regaining professional activity was significantly better in the PRC group. There was no significant difference in gripping force between the PRC and the arthrodesis group. Complications were less numerous. CONCLUSION: A mobility saving procedure as a PRC is preferable over an arthrodesis in patients with posttraumatic wrist osteoarthritis.
