The authors compare the functional outcome of 26 patients successfully treated by percutaneous osteosynthesis and 24 patients successfully treated by a short-arm thumb cast for the acute scaphoid fracture after a follow-up of at least 12 months. The patients treated by percutaneous osteosynthesis showed a significantly better range of wrist motion at the time of re-examination. Differences in persistent complaints and in grip strength compared to the uninjured wrist between both groups were statistically insignificant yet slightly in favour of the surgically treated patients. The higher suitability of percutaneous osteosynthesis is further supported by the significantly lower failure rate compared to conservative treatment. Based on these results, percutaneous osteosynthesis seemed to be the more favourable method of treatment of minimally and non-displaced scaphoid fractures than conservative treatment.  相似文献

Trabecular bone fractures heal through intramembraneous ossification. This process differs from diaphyseal fracture healing in that the trabecular marrow provides a rich vascular supply to the healing bone, there is very little callus formation, woven bone forms directly without a cartilage intermediary, and the woven bone is remodelled to form trabecular bone. Previous studies have used numerical methods to simulate diaphyseal fracture healing or bone remodelling, however not trabecular fracture healing, which involves both tissue differentiation and trabecular formation. The objective of this study was to determine if intramembraneous bone formation and remodelling during trabecular bone fracture healing could be simulated using the same mechanobiological principles as those proposed for diaphyseal fracture healing. Using finite element analysis and the fuzzy logic for diaphyseal healing, the model simulated formation of woven bone in the fracture gap and subsequent remodelling of the bone to form trabecular bone. We also demonstrated that the trabecular structure is dependent on the applied loading conditions. A single model that can simulate bone healing and remodelling may prove to be a useful tool in predicting musculoskeletal tissue differentiation in different vascular and mechanical environments.  相似文献

The aim of this study was retrospective study of our first 100 consecutive cases of prostatic cancer, operated by laparoscopic approach and comparison with 100 cases of open retropubic radical prostatectomy (RRP) at our department, focusing on operative data and morbidity. From June 1999 to August 2003 we have performed first consecutive 100 laparoscopic radical prostatectomies (LRP), all according to Montsouris technique. In this study we have compared the results with 100 patients who underwent from May 1997 to August 2003 open RRP. Mean operative time was shorter after RRP (155 vs. 234 min, p = 0.018). Mean blood loss was significantly lower in LRP group (446 vs. 710 ml, p < 0.001). Mean catheter duration time (6.4 vs. 10 days, p < 0.001) and hospital stay (8.6 vs. 11 days, p < 0.001) were significantly shorter in LRP group. There was no statistically significant difference in complication rate in both groups (p = 0.139). Laparoscopic radical prostatectomy is a safe procedure for the patient and complications do not appear more often than in the open operation. In LRP we detected shorter mean catheter duration time, shorter hospital stay and less blood loss. This procedure demands perfect knowledge of the laparoscopic operative technique and due to long-term learning curve, the procedure could be done only in particular centers, where exist suitable equipment and also experienced operators in laparoscopic technique.  相似文献

Compared with lower extremity plyometrics, data concerning the loads and intensity associated with upper extremity plyometrics are limited. The purpose of this study was to compare vertical ground reaction force (vGRF) characteristics between the clap push-up and box drop push-ups from 3.8 cm (BD1), 7.6 cm (BD2), and 11.4 cm (BD3) heights and limbs (dominant, nondominant). Twenty-two healthy active male subjects (age 25.9 ± 1.3 years, height 1.8 ± 0.08 m, mass 87.6 ± 12 kg) performed 4 repetitions of each push-up variation in a random order. Four dependent variables, peak vGRF, time-to-peak vGRF, loading rate (LR), and propulsion rate (PR) were calculated for each extremity. Statistical analysis consisted of separate limb by variation repeated measures analysis of variance. In addition, ground contact time (GCT) was statistically compared between variations. The GCT for the clap push-up (p = 0.033) was significantly less than that for BD1 and BD2. No significant differences were revealed for time-to-peak vGRF (p = 0.717). Peak vGRF was significant between dominant and nondominant limbs (p = 0.045). Post hoc analysis of a significant limb by variation interaction in LR (p < 0.001) revealed the dominant limb to be significantly greater than the nondominant one in all 4 push-up variations. Furthermore, for both limbs, the clap LR was significantly greater than BD1, BD2, and BD3. The clap PR was significantly greater than BD1, BD2, and BD3. These data add rationale for determining upper extremity plyometric progression. The peak vGRFs are similar, and altering the box height did not affect peak vGRF. In contrast, the clap demonstrated the highest LR and PR suggesting that it may be a more powerful exercise than BD1, BD2, and BD3. The higher LR (Clap and BD3) for the dominant extremity illustrates bilateral disparity in the rate of eccentric loading.  相似文献

Minimally invasive plate osteosynthesis(MIPO) has been considered as an alternative for fracture treatment. Previous study has demonstrated that MIPO technique has the advantage of less soft tissue injury compared with open reduction internal fixation (ORIF). However, the comparison of callus formation and mineralization between two plate osteosynthesis methods remains unknown. In this experiment, ulna fracture model was established in 42 beagle dogs. The fractures underwent reduction and internal fixation with MIPO or ORIF. Sequential fluorescent labeling and radiographs were applied to determine new callus formation and mineralization in two groups after operation. At 4, 8 and 12 weeks postoperatively, the animals were selected to be sacrificed and the ulna specimens were analyzed by Micro-CT. The sections were also treated with Masson staining for histological evaluation. More callus formation was observed in MIPO group in early stage of fracture healing. The fracture union rate has no significant difference between two groups. The results indicate that excessive soft tissue stripping may impact early callus formation. As MIPO technique can effectively reduce soft tissue injury with little incision, it is considered to be a promising alternative for fracture fixation.  相似文献

This study evaluated the usefulness of the implanted peripheral nerve stimulator in patients with pain following injury to a peripheral nerve. The patient sample (n = 17) consisted of 7 men and 10 women with a mean age of 48 years (SD = 18 years). The mean follow-up time since implantation of the stimulator was 21 months (SD = 15 months). Workers' compensation and/or litigation were involved in 11 cases. Peripheral nerve stimulators were placed in the upper extremity in 12 patients and in the lower extremity in 5 patients. Pain relief following implantation was rated as excellent by five patients, good by six patients, fair by four patients, and poor by two patients. A statistically significant decrease in reported pain level was found postoperatively (p < 0.0003). There was no statistically significant difference in postoperative pain level between men and women (p = 0.30), between cases involving workers' compensation or litigation and those not involving these issues (p = 1.0), or between patients who received an upper-extremity implant and those who received a lower-extremity implant (p = 0.56). Of the 12 patients who were unable to work before the operation, 6 returned to work after the operation. In conclusion, peripheral nerve stimulators can be useful in decreasing pain in carefully selected patients with severe neurogenic pain.  相似文献

Internal fixation of fractures of the proximal humerus needs a high stability of fixation to avoid secondary loss of fixation. This is especially important in osteoporotic bone. In an experimental study, the biomechanical properties of the angle-fixed Philos plate (internal fixator) and a double-plate osteosynthesis using two one-third tubular plates were assessed. The fracture model was an unstable three-part fracture (AO type B2). Eight pairs of human cadaveric humeri were submitted to axial load and torque. In the first part of the study, it was assessed to which degree the original stiffness of the humeri could be restored after the osteotomy by the osteosynthesis procedure. Subsequently, subsidence during 200 cycles of axial loading and torque was analysed. During axial loading, the Philos plate was significantly stiffer and showed less irreversible deformation. Two double-plate fixations, but none of the Philos plate osteosynthesis, failed. During torsion, there were no significant differences between the two implants. From the biomechanical point of view, the angle-fixed Philos plate represents the implant of choice for the surgical fixation of highly unstable three-part fractures of the proximal humerus, as the internal fixator system is characterised by superior biomechanical properties.  相似文献

BACKGROUND: Treatment of leg length inequality via lengthening of the shorter extremity is an infrequent orthopedic procedure due to the requirement of special distraction devices and possible serious complications. Essential qualitative changes in operative technique development are associated with the name of G. A. Ilizarov, who paved the way for the autoregenerate gradual distraction method in the 1950s. MATERIAL AND METHODS: In the years 1990 through 2006 a total of 57 patients underwent femur lengthening via gradual distraction using various types of external fixators at the Department of Pediatric Surgery, Orthopedics, and Traumatology, Faculty Hospital in Brno. The quality of bone healing was monitored and a number of parameters followed and statistically evaluated using regularly scheduled X-ray examinations. RESULTS: In 11 cases we had to remove the external fixator following the distraction phase, perform an osteosynthesis via a splint and fill the distraction gap via spongioplasty. The bone healing was satisfactory in the remaining 46 patients and the lengthened bone required no other fixation method. The analysis showed statistically significant deceleration in bone healing following distraction in female patients over 12 years of age, and in boys over 14 years of age. Lack of periosteal callus five weeks after surgery always signified serious problems in further healing. Severe complications were recorded in 11 cases during the distraction phase, and in 9 cases after the removal of the distraction apparatus. CONCLUSIONS: The aim of this report was to present the results of our study of distraction gap bone healing using the gradual lengthening approach.  相似文献
