RESUMEN
BACKGROUND AND AIMS: This study assessed the clinical and radiographic results 3 to 8 years after an arthroscopic ACL reconstruction using a hamstring graft with interference screw fixation on femoral and tibial sites. MATERIAL AND METHODS: Seventy-six of 100 patients, who underwent an arthroscopic ACL reconstruction, could be re-examined with a mean follow-up of 5 years. RESULTS: The mean Tegner activity score was 4 (scale: 0 to 10) before surgery, and 5 at the follow-up. Fifty-four patients (78%) achieved a satisfactory result in the IKDC rating. The mean Lysholm score was 85 (scale: 0 to 100), the score being better in patients without meniscal resection than those with (P = 0.04). The mean side-to-side difference in anterior-posterior knee laxity was 1.8 mm, and 62 patients (90%) had good stability. Sixty-four patients (93%) had normal range of motion of the knee. Twelve patients (46%) with meniscal resection had osteoarthritic changes, compared with only 8 of those (20%) without meniscal resection (P = 0.03). CONCLUSIONS: This medium-term follow-up study showed that good stability and function and normal range of motion of the knee can be achieved in majority of the patients who have undergone an ACL reconstruction with a hamstring graft and interference screw fixation.

We treated 93 consecutive patients, average age 53 (16-90) years, with closed humeral shaft fractures applying a functional brace immediately after injury. Seventy-two (77%) fractures healed without problems. There were significantly more consolidation problems in fractures in the proximal third (46% consolidated) compared to those at the middle (81% consolidated) and distal third (86% consolidated) of the shaft. Logistic regression analysis revealed the only predictive factor in respect to successful brace treatment was fracture location. No significant difference was found in respect to healing between different AO-type fractures.

BACKGROUND AND AIMS: The incidence of diabetic Charcot neuroarthropathy has increased. The purpose here was to study the current diagnostics and treatment of the Charcot foot. MATERIALS AND METHODS: During a time period from 1994 to 2000, a total of 36 feet were diagnosed as cases of diabetic Charcot neuroarthropathies. A retrospective analysis of patient records and radiographs was undertaken. A review of the recent literature is presented. RESULTS: 29 cases were diagnosed in the dissolution stage, 2 in coalascence, and 5 in the resolution stage. The diagnostic delay averaged 29 weeks. Treatment with cast immobilisation ranged from 4 to 37 weeks (mean 11 weeks). A total of 14 surgical procedures were carried out on 10 patients: six exostectomies, four midfoot arthrodeses, one triple arthrodesis, one tibiocalcaneal arthrodesis and two below-knee amputations. A radiological fusion was achieved in two thirds of the attempted arthrodeses. CONCLUSIONS: A physician should always consider the Charcot neuroarthropathy when a diabetic patient has an inflamed foot. In the absence of fever, elevated CRP or ESR, infection is a highly unlikely diagnosis, and a Charcot process should primarily be considered. The initial treatment of an inflamed Charcot foot consists in sufficiently long non-weightbearing with a cast, which should start immediately after the diagnosis. The prerequisites of successful reconstructive surgery are correct timing, adequate fixation and a long postoperative non-weightbearing period. In the resolution stage most Charcot foot patients need custom-molded footwear.

We analyzed data from 87 patients who had displaced closed or open grade I simple or spiral wedge tibial shaft fractures caused by low-energy impact. Fifty-four patients were treated with plaster cast and 33 with intramedullary locking nail (IMLN). Delayed union only occurred in 8 patients after plaster cast treatment. Forty-two patients in the IMLN group and one in the plaster cast group suffered from anterior knee pain. Final treatment outcome, healing time, hospitalization time and duration of sick leave were assessed on the basis of 25 matched pairs of patients. Mean healing time, hospitalization time and sick leave in the plaster cast and IMLN groups were 19 (SD 6.7) and 12 (SD 4.4) weeks (P<0.001); 8 (SD 4.8) and 7 (SD 2.7) days (P=0.686); and 195 (SD 81) and 106 (SD 31) days (P=0.001), respectively. No difference was found between plaster cast and IMLN groups when the outcome was evaluated using the criteria of Johner and Wruhs.

Hypertonic saline can be used for initial fluid administration before spinal anesthesia. It is effective in small-volume fluid resuscitation. This randomized double-blinded study compared the effects of 7.5% hypertonic saline (HS) and 0.9% normal saline (NS) in doses containing 2 mmol/kg of sodium in 40 ASA physical status I-II patients undergoing arthroscopy or other lower limb surgery under spinal anesthesia. We infused 1.6 mL/kg of HS or 13 mL/kg of NS for initial fluid administration before spinal anesthesia induced with a 10-mg dose of 0.5% hyperbaric bupivacaine. Etilefrine was administered to maintain mean arterial pressure at > or =80% of its control value. Systolic and diastolic blood pressure, heart rate, and cardiac index did not differ between the groups, and the amount of etilefrine administered was similar in the treatment groups. In all our patients, the plasma sodium concentrations were within the normal range after surgery and serum osmolality was within the normal range after spinal anesthesia. The time and the volume of the first micturition were similar in both groups, despite the much smaller amount of infused free water in the HS group. We conclude that 7.5% HS was as good as NS for the initial fluid administration before spinal anesthesia when the amount of sodium was kept unchanged.

BACKGROUND AND AIMS: The aim of this retrospective study was to compare the relative costs of treating simple and spiral wedge (requiring closed reduction under anaesthesia) tibial shaft fractures in a plaster cast or with intramedullary locking nail. MATERIAL AND METHODS: The material consisted of 26 fractures treated in a plaster cast and 51 fractures treated with an intramedullary locking nail. The costs caused by the direct costs (treatment, hospitalisation, and outpatient appointments) as well as indirect costs (lost productivity) were taken into account. Costs caused by complications were also included in the analysis. RESULTS: Mean direct costs per patient were FIM 22920 and FIM 26952 and mean overall costs per patient were FIM 120486 and FIM 82224 in plaster cast and intramedullary locking nailing groups, respectively (FIM 1 = USD 0.19). The higher mean overall costs of the plaster cast group were attributable to the longer sick leave periods in this group (218 days in plaster cast group and 124 in intramedullary nailing group). CONCLUSION: Plaster cast treatment of simple and spiral wedge tibial shaft fractures requiring closed reduction under anaesthesia is more expensive to society than operative treatment with intramedullary locking nail.

The isokinetic performance of thigh muscles was evaluated in 37 patients at an average of 7 years after sustaining a fracture of the tibial plateau. The mean torque deficit in the quadriceps of the injured limb was an average of 15% at a speed of 60 degrees/s and 16% at 180 degrees/s, while the corresponding deficits in the hamstrings were 3% and 8%. The radiological appearance of the injured knee correlated significantly to the quadriceps deficit at both speeds. Limited knee movement and thigh atrophy also correlated with the deficit at the lower speed. The strength deficit tended to decrease during follow-up. A multiple step-wise regression analysis showed that the radiological result, length of follow-up and thigh atrophy accounted for 47% of the variation in loss of quadriceps strength. At the higher speed, the functional result was associated with the deficit in quadriceps strength, and older patients had greater deficits than younger. Regression analysis indicated that the radiological and functional result accounted for 31% of the variation in quadriceps strength. Anatomical restoration of the tibial plateau and good muscle rehabilitation are important in obtaining good long term results after this fracture.

Secondary osteoarthritis after tibial plateau fracture was found in 44% of 131 cases at 7.6 (3.3-13.4) years follow-up. Narrowing of the joint space was noted during the first 7 years after injury, usually in the same compartment as the fractured plateau. The incidence slightly increased with the age of patients. Removal of a meniscus during the fracture surgery resulted in secondary degeneration in 74% of the cases. When a meniscus was intact or repaired, the proportion of degenerative cases was only 37%. Normal or slight valgus alignment of the tibial plateau with intact menisci protected best against secondary degeneration. On the other hand, medial or lateral tilt of the tibial plateau with a removed meniscus was followed by osteoarthritis in most cases. The severity of articular irregularities correlated poorly with the degenerative process. Associated ligamentous injuries as well as postoperative infection increased the incidence of secondary degeneration.

The residual radioanatomic changes influencing the functional, subjective, and clinical outcome of 131 tibial condyle fractures were studied. Clinical function was found to deteriorate rapidly with increasing values of residual medial tilt of the tibial plateau, whereas lateral tilt of the plateau was well tolerated up to 5 degrees. Articular step-off up to 3 mm and condylar widening up to 5 mm had no adverse effects. Seventy percent of knees with moderate or severe instability were functionally unacceptable. It was concluded that a medial unicondylar fracture with any displacement, and all medially tilted bicondylar fractures, should be operated upon. In fracture of the lateral condyle, open reduction and internal fixation is indicated when lateral tilt or valgus malalignment exceeds 5 degrees, articular step-off exceeds 3 mm, or condylar widening exceeds 5 mm. The same limits apply to laterally tilted bicondylar fractures, provided that the medial condyle is undisplaced. Any displacement seen in the axial bicondylar fracture is an indication for surgical treatment. If there is any mediolateral instability in the extended knee joint after rigid internal fixation, repair of a collateral ligament should be considered. An avulsed anterior cruciate ligament should be fixed, if pathologic laxity exists, but the torn ligament can be ignored and reconstructed later if needed.

We analysed 131 fractures of the tibial condyles in 130 patients, using a modification of the classification of Schatzker, McBroom and Bruce (1979). The patients were reviewed at an average of 7.6 years after the injury. Fifty-five (42%) fractures had been treated conservatively and 76 (58%) operatively. Medial unicondylar and medially tilted bicondylar fractures tended to redisplace into varus position and lateral unicondylar and laterally tilted bicondylar fractures into valgus. There were significant differences when the results were evaluated according to the methods of Hohl and Luck (1956) and Rasmussen (1973). Using our method in conservatively treated cases, the subjective results were acceptable in 49.1%, the functional results in 60.0% and the clinical results in 52.7%. In cases treated by operation the equivalent figures were 57.9%, 73.7% and 52.6%. The poorest results followed displaced medial condylar and medially tilted bicondylar fractures. Varus alignment of the tibial plateau was tolerated worse than valgus alignment.

Our report concerns 2 patients who developed delirium after an epileptic attack during mianserin treatment. In both cases the EEG showed a change with periodic sharp slow complexes similar to that seen in Creutzfeldt-Jakob disease. The symptoms subsided, however, and the EEG normalized after the antidepressant was discontinued, suggesting a noxious response to mianserin. If Creutzfeldt-Jakob-like changes in the EEG occur, the possible effect of antidepressant medication should be considered.
