Although patients improved over the 2-year follow-up regardless of initial treatment, those undergoing decompressive surgery reported greater improvement regarding leg pain, back pain, and overall disability. The relative benefit of initial surgical treatment diminished over time, but outcomes of surgery remained favorable at 2 years. Longer follow-up is needed to determine if these differences persist.
The impact of hip (THA) and knee arthroplasty (TKA) on patients' health-related quality of life (HRQOL), physical ability and functioning was assessed in a two year follow-up study of 276 hip and 176 knee patients. The eligibility criteria were a diagnosis of primary arthrosis, a primary operation, and total joint arthroplasty. Patients were interviewed by questionnaire prior to the operation and 6, 12 and 24 months after the surgery. Subjective health outcomes were assessed with the Nottingham Health Profile and the 15D, a fifteen dimensional HRQOL measure. Patients' physical ability was assessed using measures of activities of daily living, and of physical mobility. Patient related outcome variations were analyzed by regression models. Major improvements were observed for pain, sleep and physical mobility. On average, in most of the quality of life dimensions the patients attained a similar quality of life as the comparable general population and only 4.7% of hip and 9.7% of knee patients had a worse HRQOL score at all three post-operative measurements than at baseline. Naturally, those with the poorest HRQOL pre-operatively gained most from the operation. High age did not lessen HRQOL gains from THA, but in TKA the oldest patients gained least in terms of 15D scores. Hip, but not knee patients with a long education tended to have greater improvements in quality of life and functional ability.
Results after the operative treatment of 41 severe proximal fractures of the humerus are reported. The fractures were classified according to Neer (1970a). The aim of treatment was accurate reduction and stable fixation of the fracture with screws or with screws and a plate. When scored according to Neer's (1970a) functional assessment, results in the 31 patients re-examined more than 1 year postoperatively were excellent or satisfactory in 23 patients. Results were excellent or satisfactory in 14/15 patients with type III fractures, in 7/11 with IV, and 2/4 with type VI. In the only re-examined patient with a type V fracture the result was unsatisfactory. The most common technical error was a too high positioning of the AO plate and persistent varus deformation of the head of the humerus. High positioning of the plate caused post-operative restriction in the movements of the glenohumeral joint because the implant impinged under the acromion during abduction. No aseptic necrosis of the humeral head was observed. Of the patients of working age all but one returned to their preoperative occupations within a mean of 3.5 months after surgery.
The extensive benefits of the total hip (THA) and knee (TKA) replacements are well documented, but surprisingly little is known about their economics. We assessed costs, cost-effectiveness (C/E), and patient-related C/E variances in THA and TKA from data on 276 THA and 176 TKA patients. Patients with primary arthrosis, primary operation, and total joint replacement were recruited from seven hospitals between March 1991 and June 1992. Their use of health and other welfare services together with health-related quality of life (HRQoL) were measured before the surgery and at 6, 12, and 24 months postoperatively. HRQoL was assessed by the 15D, a 15-dimensional HRQoL instrument, and the Nottingham Health Profile. Costs were assessed from questionnaire responses, the Finnish Hospital Discharge Register, and Finnish Arthroplasty Register. Total hospital costs per patient were 45,000 FIM (US $10,500) for THA and 49,600 FIM (US $11,500) for TKA. Prosthesis costs comprised 21% of these costs in THA and 24% in TKA. On average, hip patients gained more in terms of HRQoL, and the operations were more cost-effective. The C/E ratio for younger (< or = 60 years) knee patients did not differ from those in all age groups of hip patients, whereas TKAs in those over 60 years had a worse C/E ratio compared with all other patient subgroups. It was concluded that allocation efficiency can be improved by considering not only the intervention but also patient characteristics such as age. Indeed, the C/E ratio varied more across age groups of knee patients than between average THA and TKA patients.
Medial displacement of the long tendon of the biceps brachii muscle is a rare condition associated with degenerative or traumatic ruptures of the rotator cuff. This condition was recorded in nine shoulders during 45 reconstructive procedures on the rotator cuff. Five of the displacements were complete, leaving the tendon medially displaced in a fascial sling; four were incomplete, allowing a to-and-fro medial displacement of the tendon out of the intertubercular groove. Anatomical dissections on eight shoulders showed that the coracohumeral ligament is the key ligament which keeps the biceps tendon aligned in the sulcus: transection of the medial part of the ligament allows the tendon to be medially displaced. There was no pathognomonic clinical sign of the luxation or subluxation. Since abnormal movement of the tendon in the sulcus may be an important cause of shoulder pain, the condition should be carefully looked for during reconstructive procedures on the rotator cuff. Tenodesis of the displaced tendon is recommended, either as the sole procedure or in combination with other reconstructive measures.
We randomised a total of 94 patients with long-standing moderate lumbar spinal stenosis (LSS) into a surgical group and a non-operative group, with 50 and 44 patients, respectively. The operative treatment comprised undercutting laminectomy of stenotic segments, augmented with transpedicular-instrumented fusion in suspected lumbar instability. The primary outcome was the Oswestry disability index (ODI), and the other main outcomes included assessments of leg and back pain and self-reported walking ability, all based on questionnaire data from 85 patients at the 6-year follow-up. At the 6-year follow-up, the mean difference in ODI in favour of surgery was 9.5 (95% confidence interval 0.9-18.1, P-value for global difference 0.006), whereas the intensity of leg or back pain did not differ between the two treatment groups any longer. Walking ability did not differ between the treatment groups at any time. Decompressive surgery of LSS provided modest but consistent improvement in functional ability, surpassing that obtained after non-operative measures.
