“Sandwich” Plating for Intra-articular Distal Radius Fractures with Volar and Dorsal Metaphyseal Comminution 总被引:11,自引:0,他引:11
Introduction Intra-articular distal radius fractures with volar and dorsal comminution present a special challenge to the hand surgeon.
Methods Ten patients formed the study cohort. All plates were low profile and stainless steel. Radiographic parameters, range of motion,
and strength compared to the uninjured side were recorded. Functional outcome was evaluated by Disabilities of the Arm, Shoulder
and Hand (DASH) questionnaire and Gartland and Werley scoring system.
Results Median age at surgery was 58 years (range, 24 to 86). Mean follow-up was 17 months (range, 12 to 28). According to the AO
classification system, there were three type C2 and seven type C3 fractures. Median preoperative dorsal angulation was 24 deg;
median postoperative dorsal angulation was 3 deg. Eighty percent (8) of the fractures also had an intra-articular step-off
or gap, all of which were corrected to neutral by the procedure. Compared with the contralateral side, mean extension and
flexion were 73 and 75%, respectively, pronation and supination were 95 and 88%, respectively, and grip strength and thumb
pinch were 72 and 87%, respectively. Mean postoperative DASH score was 16 points, and 70% (7) of the patients had Gartland
and Werley scores of good or excellent. None of the patients needed to have their plates removed, and no extensor tendon rupture was reported.
Conclusions The “sandwich” plating technique is an effective method of regaining near-anatomic reconstruction of intra-articular, volarly
and dorsally comminuted distal radius fractures. Results from this study demonstrate that patients can expect to regain about
80% of their range of motion and strength. Moreover, 70% of the patients will have good to excellent functional outcomes. This is the first study to examine range of motion and functional outcome of low-profile “sandwich”
plating without plate removal. 相似文献

Functional outcome and complications after volar plating for dorsally displaced, unstable fractures of the distal radius 总被引:8,自引:0,他引:8
PURPOSE: Despite the recent popularity of volar plating for dorsally displaced distal radius fractures there is a paucity of data documenting the results of this treatment method. The purpose of this study was to determine the functional outcome of patients treated with volar fixed-angle plating for dorsally displaced, unstable distal radius fractures. METHODS: We reviewed the records of all patients treated at our institution with internal fixation using volar plates for dorsally displaced, comminuted distal radius fractures. Patients with follow-up periods shorter than 12 months were excluded from the study. Outcomes were evaluated at the latest follow-up examination with the Disabilities of the Arm, Shoulder, and Hand and the Gartland and Werley scoring systems. RESULTS: We studied 41 patients with a mean age of 53 years. The average follow-up period was 17 months. All fractures were stabilized with volar locking plates. Radiographs in the immediate postoperative period showed a mean radial height of 11 mm, mean radial inclination of 21 degrees , and mean volar tilt of 4 degrees. At fracture healing the mean radial height was 11 mm, mean radial inclination was 21 degrees, and mean volar tilt was 5 degrees. The average score on the Disabilities of the Arm, Shoulder, and Hand questionnaire was 14 and all patients achieved excellent and good results on the Gartland and Werley scoring system, indicating minimal impairment in activities of daily living. Nine patients experienced postoperative complications. There were 4 instances of loss of reduction with fracture collapse, 3 patients required hardware removal for tendon irritation, 1 patient developed a wound dehiscence, and 1 patient had metacarpophalangeal joint stiffness. CONCLUSIONS: Patients with unstable, dorsally displaced fractures of the distal radius treated with volar fixed-angle devices have good or excellent functional outcomes despite a high complication rate. When compared with previous reports on dorsal plating volar plates appear to have a higher incidence of fracture collapse but a lower rate of hardware-related complications. Complex fracture patterns thus mandate a careful and individualized approach. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level III. 相似文献

Volar versus dorsal plating in the management of intra-articular distal radius fractures 总被引:6,自引:0,他引:6
PURPOSE: To compare the complications and functional and radiographic outcomes of volar and dorsal plating of intra-articular distal radius fractures. METHODS: This retrospective review included 34 patients found by searching a database of 350 patients treated for distal radius fractures. Inclusion criteria were (1) at least 1 year of follow-up data and (2) open reduction and internal fixation of a multifragmentary fragment intra-articular distal radius fracture with either a nonlocking volar or dorsal plate. Twenty patients were treated with a dorsal plate and 14 patients were treated with a volar nonlocking plate. Objective and subjective outcome parameters were compared between the 2 groups. Objective evaluations included wrist range of motion, grip strength, and preoperative and postoperative radiographic parameters (radial inclination, palmar tilt, ulnar variance, fracture pattern). Subjective evaluations were performed using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire score and the Gartland and Werley score. RESULTS: Volar plating resulted in a significantly better Gartland-Werley score compared with dorsal plating. There were no significant differences in the DASH score.Volar collapse was documented in 5 of the 20 patients in the dorsal plating group, which resulted in a mild loss of pronation compared with the volar plating group. No collapse occurred in the volar plating group. In addition the difference in the percentage of wrist range of motion compared with the contralateral wrist was not significant. Dorsal plating was associated with a ruptured extensor indicis tendon in 1 patient; secondary surgical procedures were required in 4 patients (tenolyses and radial styloidectomy). Volar plating was associated with median nerve neuropathy in 2 patients and intersection syndrome in one. CONCLUSIONS: Although both groups of patients had similar DASH scores the functional outcome in terms of Gartland and Werley scores was better in the volar plating group. In addition there was a higher rate of volar collapse and late complications in the dorsal plating group compared with the volar plating group.

PURPOSE: To evaluate objective functional and radiographic outcomes after internal fixation of acute, displaced, and unstable fractures of the distal aspect of the radius in adults by using a low-profile dorsal plating system. Our hypothesis was that the low-profile dorsal plating system would allow for a reduction of extensor tendon irritation and pain and provide stable osseous fixation. METHODS: Sixty consecutive unstable fractures in 59 patients were treated by open reduction internal fixation using a low-profile dorsal plating system. There were 29 type A, 14 type B, and 8 type C fractures (AO classification system). Fifty patients with 51 fractures returned for outcomes assessment by physical examination, plain radiographs, and completion of a validated musculoskeletal function assessment questionnaire. The minimum follow-up period was 1 year; the mean follow-up period was 24 months. Clinical evaluation was performed and plain radiographs were assessed for maintenance of immediate postoperative reduction and implant position. Objective functional assessment was obtained through the Disabilities of the Arm, Shoulder, and Hand questionnaire. RESULTS: Outcomes analysis showed no cases of extensor tendon irritation or rupture. Hardware removal was performed in 1 patient but no extensor tendon irritation or rupture was evidenced. The mean Disabilities of the Arm, Shoulder, and Hand score was 11.9; implant-related discomfort was minimal. All patients had an excellent (31 patients) or good (19 patients) result according to the scoring system of Gartland and Werley. The mean active range of motion was greater than 80% of that of the contralateral wrist in flexion/extension, pronation/supination, and ulnar/radial deviation. Extensor tendon function was unimpaired in all patients. Grip and pinch strength averaged 90% and 94% of the contralateral sides, respectively. Radiographic evaluation showed no change in fracture reduction or implant position. CONCLUSIONS: The treatment of distal radius fractures with a low-profile stainless steel dorsal plating system is a safe and effective method that provides stable internal fixation and allows for full extensor tendon glide and full metacarpophalangeal joint motion. Objective outcome testing showed uniformly good to excellent recovery of wrist and hand function in all patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV. 相似文献

BACKGROUND: There is a paucity of data in the literature documenting the functional outcomes for patients who have been managed with a dorsal plate because of a distal radial fracture. The purpose of the present study was to determine the functional outcome and complications following dorsal plating for dorsally displaced, unstable fractures of the distal part of the radius. METHODS: The records of all patients who had been managed at our institution with dorsal plating because of a comminuted, dorsally displaced fracture of the distal part of the radius were reviewed. Patients with less than twelve months of follow-up were excluded from the study. Outcomes were evaluated at the time of the latest follow-up with use of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Gartland and Werley scoring system. RESULTS: Twenty-eight patients (nineteen women and nine men) with a mean age of forty-two years formed the basis of the study. The mean duration of follow-up was twenty-one months. Nineteen patients had been treated with a Synthes pi plate, and nine had been treated with a low-profile plate. There were no instances of loss of reduction, malunion, or nonunion. The mean score on the DASH questionnaire was 14.5 points. All patients had an excellent (nineteen patients) or good (nine patients) result according to the scoring system of Gartland and Werley. Nine patients had postoperative complications requiring repeat surgical treatment for hardware removal or extensor tendon reconstruction. All nine reoperations were performed in patients who had been treated with a Synthes pi plate, while none were performed in patients who had been treated with a low-profile plate (p < 0.025). Four complications occurred in patients who had been treated with a titanium plate, and five complications occurred in patients who had been treated with a stainless-steel plate (p = 0.71). CONCLUSIONS: Patients in whom a dorsally displaced distal radial fracture is treated with a titanium or stainless-steel Synthes pi plate have a significantly increased risk of complications compared with those in whom such a fracture is treated with a low-profile plate. Regardless of the type of plate used, all of the patients in the present study had a good or excellent long-term functional outcome. 相似文献

OBJECTIVE: To study the functional outcome of displaced distal radius fractures treated by open reduction and internal fixation with the use of fragment-specific fixation. METHODS: Fifteen consecutive displaced distal radius fractures (5 extra-articular and 10 intra-articular) were treated using the Trimed distal radius fixation system (Trimed, Valencia, CA). Radiographic assessment and range of motion of the affected wrist were evaluated postoperatively. Functional outcomes were evaluated with use of the Disabilities of the Arm, Shoulder, and Hand questionnaire and the Gartland and Werley scoring system. RESULTS: The mean follow-up was 11 months. The patients initiated controlled passive and active motion exercises during the first week. The mean score on the Disabilities of the Arm, Shoulder, and Hand questionnaire was 16 points. The mean return to work was 12 weeks. The functional outcome was 80% excellent or good by the Gartland and Werley scoring system for intra-articular fractures and 80% excellent for extra-articular fractures. Range of active motion in intra-articular fractures was measured 60 degrees wrist extension, 64 degrees flexion, 65 degrees pronation, and 70 degrees supination, and for extra-articular fractures, 75 degrees extension, 70 degrees flexion, 80 degrees pronation, and 75 degrees supination. There was failure of fixation with loss of the reduction that was achieved at the time of operation in one patient. CONCLUSIONS: Fragment-specific fixation of unstable distal radius fractures using the Trimed system appears to be effective. Anatomic reduction, earlier range of motion, and improved functional results can be achieved using low-profile implants. 相似文献

PURPOSE: To assess the clinical, radiographic, and functional outcome of treating intra-articular distal radius fractures with fragment-specific fixation. METHODS: A retrospective review of 81 patients with 85 intra-articular distal radius fractures who were treated with fragment-specific fixation was performed. Minimum time to follow-up evaluation was 1 year, with a mean time of 32 months. The immediate postoperative films were compared with those taken at the final follow-up evaluation. Radiographs of the uninjured wrist were also obtained at the final follow-up evaluation for comparison. Patients were examined for wrist and finger range of motion, deformity, and grip strength, and they completed a standard Disabilities of the Arm, Shoulder, and Hand outcome survey. RESULTS: According to Gartland and Werley scoring there were 61 excellent and 24 good results. Flexion and extension of the surgically treated wrist at the final follow-up evaluation averaged 85% and 91%, respectively, of the uninjured wrist; grip strength averaged 92% compared with the uninjured side. The average Disabilities of the Arm, Shoulder, and Hand outcome score for the injured wrist was 9. Sixty-two percent of patients achieved a 100 degrees arc of flexion and extension and normal forearm rotation by postoperative week 6. Radiographic alignment was maintained between immediate postoperative and final follow-up films, and there were no cases of symptomatic arthritis at the final follow-up evaluation. CONCLUSIONS: Fragment-specific fixation is a reasonable alternative for treating intra-articular fractures of the distal radius. At final follow-up evaluations, patients had good to excellent results with respect to range of motion, grip strength, radiographic alignment, and satisfaction scores. Stable fixation allowed starting active and passive motion of the wrist without compromising postoperative alignment. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV. 相似文献

Outcome after surgery of distal radius fractures: no differences between external fixation and ORIF 总被引:2,自引:2,他引:0

The purpose of this study was to determine the most appropriate surgical treatment from three procedures used for fractures of the distal radius. In a retrospective comparative study, 166 out of 237 patients who underwent surgery for AO/ASIF A3 or C2 distal radius fractures were evaluated. Surgical procedures were external fixation or open reduction and internal fixation with either palmar or dorsal plates. Radiological outcomes were palmar tilt, radial angle, radial length and ulnar variance. Functional outcomes were range of motion and grip strength. In addition, outcomes according to Gartland and Werley and the Disabilities of the Arm, Shoulder and Hand questionnaire were compared. Further outcome criteria were the treatment time and the number of complications. Data were analysed using an analysis of variance statistical procedure respective of the χ2-test. Open reduction and internal fixation, in particular palmar plate fixation, demonstrated the best radiological and functional results. Subjective assessment of ORIF proved better than that of external fixation as treatment time was shorter and complications were more rarely seen. However, most of the differences between groups were not significant. Although there were no significant differences between groups, our data indicates that most dorsally displaced distal radius fractures can be treated successfully by open reduction and internal fixation. Palmar plate fixation seems to have slight advantages compared to both the external fixation and dorsal plate fixation surgical procedure. 相似文献

Fractures of the distal radius are commonly treated with cast immobilisation; however, those potentially unstable injuries with dorsal comminution may need operative intervention. This intervention is usually with manipulation and Kirschner wires but advances in locking-plate technology have enabled surgeons to achieve anatomical reconstruction of complex fracture patterns, even in poor-quality osteoporotic bone.To ascertain if fixed-angle volar-locked plates confer a significant benefit over manipulation and Kirschner-wire stabilisation, we prospectively randomised 56 adult patients with isolated, closed, unilateral, unstable extra-articular fractures into two treatment groups, one fixed with K-wires and the other fixed with a volar locking plate.Functional outcomes were assessed using Gartland and Werley and Disabilities of the Arm, Shoulder and Hand (DASH) scores. These were statistically better in the plate group at 3 and 6 months. Radiological assessment showed statistically better results at 6 weeks, 3 months and 6 months, post-operatively. In the plate group, there was no significant loss of fracture reduction. 相似文献

PURPOSE: To report our experience using a fixed-angle volar plate in conjunction with a corrective osteotomy and cancellous bone graft for the treatment of distal radius malunions with dorsal angulation in 4 patients. METHODS: Four consecutive patients had a volarly based opening wedge osteotomy with a fixed angle volar plate and cancellous bone grafting for the treatment of a dorsally angulated distal radius malunion. Data collected retrospectively included a visual analog pain scale, grip strength, range of motion, radiographic parameters, and each patient's subjective functional outcomes as measured by the Disabilities of the Arm, Shoulder, and Hand questionnaire. Motion, strength, and radiographic values were compared with the contralateral arm for each patient. RESULTS: The average time from initial fracture to corrective osteotomy was 346 days. The average length of follow-up evaluation was 13.5 months. The flexion-extension arc of motion increased an average of 21 degrees to a value of 84% of the contralateral side; the pronation-supination arc of motion increased an average of 20 degrees to a value of 98% of the contralateral side. The average tilt of the radius improved from 26 degrees extension to 2 degrees extension; the average radial inclination improved from 22 degrees to 24 degrees; the average ulnar variance excluding the 1 patient who had a distal ulna resection improved from 5 mm to 1 mm. The average retrospective Disabilities of the Arm, Shoulder, and Hand score improved from 30 to 7; the average retrospective visual analog pain scale score improved from 4.5 to 1. The average grip strength increased from 20 to 29 kg, which corresponded to 73% of the contralateral extremity. CONCLUSIONS: The rigid characteristics of fixed angle volar plates can provide an alternative to the traditional techniques of distal radius osteotomy including structural bone grafting and dorsal plate fixation or external fixation. In addition these plates are strong enough to allow for early postoperative motion. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV. 相似文献

OBJECTIVE: To evaluate the clinical, radiographic, and functional outcomes of patients aged 60 and older treated with open reduction and internal fixation using plates and screws for displaced and comminuted fractures of the distal radius. DESIGN: Retrospective, clinical research. SETTING: Tertiary care center (Level 1 trauma center) located in a large urban area. PATIENTS: Eighteen patients with an average age of 71 years (range 60-86) form the basis of this study. Patients were obtained from a surgical database of 2 hand surgeons in a tertiary care center. INTERVENTION: Open reduction and internal fixation of fractures of the distal radius using metal plates and screws designed for treatment of these injuries. MAIN OUTCOME MEASUREMENTS: Clinical (history and physical examination), plain radiographic, and functional assessments were performed at an average follow-up of 26 months (range 12-40 months). Functional outcomes were assessed using the Gartland and Werley and Disabilities of the Arm, Shoulder, and Hand scoring systems. RESULTS: Satisfactory reduction was achieved in all 18 fractures at the time of operative fixation with no instances of loss of fracture reduction during the study period. There were no cases of malunion, nonunion, or instances of device failure. We identified 4 minor complications. No patients required reoperation. Fifteen patients had an excellent (83%) and 3 had a good (17%) result according to the Gartland and Werley scoring system. The mean Disabilities of the Arm, Shoulder, and Hand score was 4.4 (range 0-14) out of a maximum 100. CONCLUSION: Our findings suggest that open reduction and internal fixation with plates and screws in patients 60 years and older with displaced and comminuted fractures of the distal radius represents a safe and effective treatment alternative. 相似文献

Results of dorsal or volar plate fixation of AO type C3 distal radius fractures: a retrospective study 总被引:1,自引:0,他引:1
PURPOSE: The aim of this study was to define the outcome after dorsal or volar plating of Association for Osteosynthesis (AO) type C3 distal radius fractures based on the fracture morphology. METHODS: Twenty-nine patients with AO type C3 distal radius fractures were surgically managed between 1996 and 2005. Group 1 (n = 15) had volar plating. Group 2 (n = 14) had dorsal plating. Outcomes were evaluated at an average of 22 months after surgery. Statistical analysis was performed using the Wilcoxon test and chi-square test. RESULTS: No significant differences were seen for the scores of Gartland and Werley, Castaing, Stewart I and II, Green and O'Brien, and Disability of the Arm, Shoulder and Hand between the 2 groups. The visual and verbal pain analog scales did not show significant differences between the 2 groups. Radiology analysis showed significant difference in comparison with the contralateral side in terms of dorsopalmar inclination (3 degrees +/- 3) and distal radioulnar joint angle (98 degrees +/- 8) for the patients in group 1, whereas there were no significant differences in group 2. The development of radiographic post-traumatic arthritis was significant in both groups. Significant functional differences were seen for flexion (45 degrees +/- 15) and hand span (20 cm +/- 2) in group 1 as well as for extension (37 degrees +/- 19), flexion (42 degrees +/- 12), and radial deviation (16 degrees +/- 10) in group 2. We found more complications after dorsal plate osteosynthesis than after volar plate osteosynthesis. CONCLUSIONS: This study shows satisfactory functional and subjective outcome results in both groups. Group 1 had non-significant better functional results than group 2, whereas both groups showed good to very good radiology results. 相似文献

This study investigates the efficacy of the AO Pi-plate in the treatment of complex, intra-articular fractures of the distal radius. We retrospectively analysed the clinical and radiological results of 19 consecutive patients who underwent open reduction and internal fixation for dorsally displaced, intra-articular fractures of the distal radius using the AO Pi-plate. The final functional outcome was assessed using the Gartland & Werley scoring system. The average follow-up period was 34.3 months. Wrist movement was restored to a near normal range in all the patients. The functional outcome as measured by the Gartland & Werley scoring system showed excellent and good results in 15 (88%) of the patients. The implant was removed in 4 (23%) of the patients due to extensor tenosynovitis and restriction of flexion. This study demonstrates that although the functional outcome following fixation of complex distal radius fractures with the AO Pi-plate is good, there is a risk of developing extensor tenosynovitis and limitation of flexion. We recommend that the implant be used sparingly and if used then elective removal of the implant should be considered after fracture union. 相似文献

Dorsal plating emerged as an effective treatment for dorsally displaced distal radius fractures in the late 1980s. In addition to some mechanical advantages, this method provided a clear view of the articular surface and the ability to restore the anatomy. However, because of the frequent occurrence of extensor tendon complications in the early designs of dorsal plates, the volar approach gained favor for repairing these types of fractures. Recent improvements in dorsal plating designs have yielded increasingly thinner, precontoured plates with rounded edges and low-profile flush screw heads. These new plates have shown decreased rates of extensor tendon complications while retaining the advantages of the original dorsal approach. The authors have used this technique in more than 70 cases during a 4-year period. This article will review the history, indications, contraindications, technique, and rehabilitation for dorsal plating of dorsally angulated distal radius fractures. 相似文献

This study reports the results of open reduction and internal fixation of 26 unstable, intraarticular, dorsally displaced fractures of the distal radius using a bio-absorbable dorsal distal radius (Reunite) plate and calcium phosphate (Biobon) bone substitute. The bio-absorbable plate has the advantage of being low profile, easily contourable and angularly stable. In the majority of cases, this plate produces functional results comparable with metal plates. The Gartland and Werley score was excellent or good in 21 patients. The theoretical advantage over metal plates is in eliminating the need to remove the plate and hence the need for a second operation if implant-related extensor tenosynovitis occurs. Inflammatory tissue reaction to the degradation products of the plate is a potential concern, although the co-polymer ratio used in this plate appears to have reduced the severity of this reaction, which was seen in two patients in this series. The reduction was lost in five patients with severe dorsal comminution. Following this experience, we do not recommend this plating system for fractures with a metaphyseal gap of greater than 7 mm following reduction. 相似文献

PURPOSE: To identify the most important determinants of physician-based and patient-based scoring systems for the wrist and upper extremity after operative treatment of a fracture of the distal radius, with the hypothesis that pain is the strongest determinant of both types of scores. METHODS: Eighty-four patients were evaluated a minimum of 6 months after operative fixation of an unstable distal radius fracture using 2 physician-based evaluation instruments (the Mayo Wrist Score and the Gartland and Werley Score) and an upper extremity-specific health status questionnaire (Disabilities of the Arm, Shoulder, and Hand; DASH). Multivariate analysis of variance and multiple linear regression modeling were used to identify the degree to which various factors affect variability in the scores derived with these measures. RESULTS: The physician-based scoring systems showed moderate correlation with each other and with DASH scores. The results of multiple linear regression modeling were as follows (percent variability accounted for by the best fit model/model with top factor alone): Mayo: 54% grip and flexion arc/47% grip alone; Gartland and Werley: 70% pain, flexion arc, radiocarpal arthritis, and duration of follow-up/53% pain alone; DASH: 71% pain, forearm arc, and type of fracture/65% pain alone. CONCLUSIONS: At early follow-up, pain dominates the patient's perception of function after recovery from an operatively treated distal radius fracture as measured by the DASH score and the physician-based rating according to the system of Gartland and Werley. The Mayo Wrist Score is determined primarily by grip strength rather than pain. Because perception of pain and strength of grip have been shown to be influenced by psychosocial factors in some individuals, both patient-based and physician-based measures of wrist function may be vulnerable to illness behavior.

Distal radius osteotomy in the elderly patient using angular stable implants and Norian bone cement 总被引:1,自引:0,他引:1
PURPOSE: To report our results after testing the combination of two technologies--angular-stable locking screw implants and Norian SRS cement--in corrective osteotomies of the distal radius in the elderly. This technique eliminates donor site bone-graft morbidity and expands the indications of corrective osteotomies to older patients with osteoporotic bone. METHODS: Our retrospective series include 6 patients (5 women and 1 man) with an average age of 60 years. Three patients had corrections through a dorsal approach, 1 through a volar approach, and 2 through a combined approach. Two corrections included an intraarticular osteotomy. We used 2.4-mm volar T plates in patients approached volarly and 2.4-mm L and T plates for those approached dorsally; the osseous defect was filled with bone cement (Norian SRS). Range of motion and grip strength were measured at 16 months average follow-up. Standard wrist radiographs were taken to evaluate alignment and determine improvement. At final follow-up, patients completed the Modified Mayo Wrist score, the Modified Gartland and Werley score, and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. RESULTS: There were no perioperative complications. All corrective osteotomies healed. One patient required a Darrach procedure at 6 months. The average wrist and forearm motion was 77% of the opposite side and grip strength 88% of the opposite side. The average total correction in the sagittal plane was 22 degrees with all patients returning to neutral or better alignment. The average ulnar variance improvement was 2 mm. Average postoperative DASH was 28 points; average Modified Mayo Wrist score was 68; and the Modified Gartland and Werley score averaged 9 points. CONCLUSIONS: We believe that corrective osteotomy of the distal radius in the elderly using angular stable implants and Norian calcium phosphate cement is a safe and predictable surgical technique, even in patients with underlying osteoporosis. It eliminates donor site morbidity, and patient-rated outcome measures demonstrated acceptable daily living function return. 相似文献
