Surgical treatment of unstable distal radius fractures with volar locking plates

BACKGROUND: Surgical treatment of unstable distal radius fractures does not always yield a satisfactory outcome. The several surgical strategies available have problems associated with them. This study was undertaken to determine if volar locking plate fixation could be useful for treating unstable distal radius fractures. METHODS: This retrospective follow-up study assessed 24 fractures in 24 patients with unstable distal radius fractures surgically treated with one of three volar locking plate systems. According to the AO classification system, 7 patients had type A3 fractures, 5 patients had type C2 fractures, and the remaining 12 patients had type C3 fractures. Radiographic measurements included volar tilt, radial inclination, and ulnar variance. Clinical outcomes were evaluated by active range of motion of the wrist and forearm, grip strength, Saito's wrist score, and the Japanese Society for Surgery of the Hand version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (JSSH version of the DASH). RESULTS: At the time of final follow-up (5 months minimum) the mean volar tilt was 8.1 degrees , radial inclination was 20 degrees, and ulnar variance was 0.4 mm. Mean wrist extension measured 61 degrees, wrist flexion 55 degrees, radial deviation 23 degrees, ulnar deviation 35 degrees, pronation 87 degrees, and supination 87 degrees. Grip strength recovered to a mean of 84% of the grip strength in the contralateral limb for patients who had injured their dominant hand and to a mean of 73% for patients who had injured their nondominant hand. Saito's wrist score calculations revealed 20 excellent and 4 good results. The mean DASH disability/symptom score was 9.9 points, and the mean DASH work module score was 8.2 points. CONCLUSIONS: The present study demonstrated that unstable distal radius fractures could be successfully treated with volar locking plate systems.     

Entire flexor carpi radialis tendon harvest for thumb carpometacarpal arthroplasty alters wrist kinetics

PURPOSE: To investigate the clinical outcome of thumb carpometacarpal arthroplasty with entire-thickness flexor carpi radialis (FCR) ligament reconstruction and tendon interposition and to investigate the isokinetic wrist flexion/extension torque and flexion fatigue strength of the surgically treated wrist compared with the nonsurgically treated wrist. METHODS: Thirty-nine patients with osteoarthritis who had unilateral thumb carpometacarpal arthroplasty with the entire FCR tendon were studied prospectively with a minimum follow-up period of 24 months. Preoperative Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire score, grip, pinch, and postoperative DASH score, grip, pinch, and Biodex (Shirley, NY) isokinetic wrist flexion/extension torques were recorded. The nonsurgically treated extremity served as the control for each patient with unilateral ligament reconstruction and tendon interposition. Peak torque ratios and fatigue were measured for the control and surgically treated extremities with the Biodex. RESULTS: Postoperative DASH scores were 12 +/- 4 and were improved significantly from preoperative scores of 43 +/- 4. The surgically treated extremity showed a significantly lower wrist flexion-to-extension peak torque ratio than the control extremity. The control extremity had 2.5 times greater wrist flexion fatigue resistance than the surgically treated side. After surgery the surgically treated extremity had significantly improved grip strength and thumb-index tip pinch compared with the preoperative status. CONCLUSIONS: Our data show conclusively that wrist flexion extension torque ratio decreases and wrist flexion fatigue resistance decreases when the entire FCR tendon is harvested even though the final outcome is favorable and uniformly based on traditional DASH, grip, and pinch scores.

Abstract：

Objective To compare the treatment outcomes between locking compression plate and external fixator for treating severely comminuted distal radius fracture. Methods Forty patients of severely comminuted distal radius fractures were treated with either locking compression plate fixation via a volar approach or external fixator. Twenty-one patients were treated with locking compression plate fixation, while the other 19 patients were treated with external fixator. According to AO/ASIF classification, there were 10 type C1 fractures,15 type C2 fractures and 15 type C3 fractures.Wrist range of motion, forearm range of motion, grip and pinch strength, radiographic data (palmar tilt, radial inclination, radial height), scores by the Disabilities of the Arm,Shoulder and Hand (DASH) and by Gartland-Werley were collected at follow-up. The data were statistically analyzed to compare the clinical effects. Results Postoperative follow-up ranged from 6 to 48 months with an average of 18.8 months. According to Gartland-Werley wrist score, the excellent and good rate was 81.0% in the locking compression plate group, and 78.9% in the external fixator group. No significantly difference was detected in the ROM of flexion, extension, radial deviation, pronation, supination, grip and pinch strength, the parameter of palmar inclination, ulnar inclination and radial height and in Gartland-Werley score and DASH score between the two groups (P＞0.05). The ROM of unlar deviation in the locking compression plate group was significantly smaller than that in the external fixation group ( P＜0.05). No complication occurred in the locking compression plate group. One patient developed sympathetic reflex dystrophy postoperatively in the external fixation group. After medication and physical therapy the symptoms had resolved. Infection of the external fixator pin tract was note in another patient which was effectively treated by wound care. Conclusion Locking compression plate and external fixator lead to siunilar treatment outcomes for severely cormminuted distal radius fractures. Patient's functional requirement, age and financial status should be taken into consideration while choosing one of these procedures.     

Examination of the Pronator Quadratus Muscle during Hardware Removal Procedures after Volar Plating for Distal Radius Fractures

Background

It is not clear whether the pronator quadratus (PQ) muscle actually heals and provides a meaningful pronation force after volar plating for distal radius fractures (DRFs). We aimed to determine whether the length of the PQ muscle, which is dissected and then repaired during volar plating for a DRF, affects the forearm rotation strength and clinical outcomes.

Methods

We examined 41 patients who requested hardware removal after volar plating. We measured the isokinetic forearm rotation strength and clinical outcomes including grip strength, wrist range of motion, and disabilities of the arm, shoulder and hand (DASH) scores at 6 months after fracture fixation. During the hardware removal surgery, which was performed at an average of 9 months (range, 8.3 to 11.5 months) after fracture fixation, we measured the PQ muscle length.

Results

The average PQ muscle length was 68% of the normal muscle length, and no significant relationship was found between the PQ muscle length and the outcomes including isokinetic forearm rotation strength, grip strength, wrist range of motion, and DASH scores.

Conclusions

This study demonstrates that the length of the healed PQ muscle does not affect isokinetic forearm rotation strength and clinical outcomes after volar plating for DRFs. The results of this study support our current practice of loose repair of the PQ that is performed by most of the surgeons to prevent tendon irritation over the plate, and suggest that tight repair of the PQ is not necessary for achieving improved forearm function.

A comparative study of variable angle volar plate and bridging external fixator with K-wire augmentation in comminuted distal radius fractures

Purpose: Comminuted intraarticular distal radial fractures are difficult to treat conservatively and require operative treatment. This study compared the functional outcomes between variable angle volar plating and external fixator with K-wire augmentation in open reduction and internal fixation. Methods: A total of 62 adult patients with comminuted intraarticular distal radius fracture were randomized into 2 groups: volar plate group and external fixator group. These patients aged between 18 and 60 years had unilateral fractures, and agreed to be included in the study. Patients with a history of fracture, bilateral fracture, associated other injuries, delayed injury for more than 2 weeks, open fracture, pre-existing arthrosis or disability, psychiatric illness and pathological fracture were excluded. Patients were followed up at 6 weeks, 3 months, 6 months and 1 year. The assessment of pain, functional activity, range of motion and grip strength was done at each stage of follow-up. The pain and functional activities were assessed by patient rated wrist evaluation (PRWE) score and disabilities of the arm, shoulder and hand (DASH) score. Results: Patients in volar plate group had superior PRWE score and DASH score at each stage of followup. At 1 year follow-up, the mean PRWE score were 7.48 for volar plate group and 7.35 for external fixator group; while the mean DASH score was 4.65 for volar plate group and 5.61 for external fixator group. They had better flexion and extension range of movement. They also had better pronation and supination range of motion at initial follow-up, however the difference get attenuated by 1 year. Volar plate group had significantly better grip strength than external fixator group. Complication rates were higher in external fixation group. Conclusion: Fixation with variable angle volar plate results in early wrist mobilization, better range of movement, less pain and disability and early return of function.     

The functional outcome of acute scapholunate ligament repair in patients with intraarticular distal radius fractures treated by internal fixation

Background

Intra-articular fractures of the distal radius (DRF) are associated with a twofold increase in the risk of scapholunate ligament injury (SLI). The aim of this study was to compare functional outcome, pain, and disability between patients with operatively treated DRF and either an acute, repaired scapholunate ligament injury or no ligament injury.

Methods

We retrospectively analyzed 18 patients with an intraarticular DRF and SLI that was diagnosed and treated (Group I) and compared them with 20 patients with DRF without associated ligament injury (Group II) (20 women, 18 men; average age 55 years, range 19–72). The two cohorts were analyzed for differences in motion, grip strength, pain, Mayo wrist score, and Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score an average of 43 months (range 12–73) after surgery. Radiographic assessment included fracture union, palmar tilt, radial inclination, ulnar variance, intercarpal angles, and arthrosis (according to Knirk and Jupiter). We used T-tests to compare range of motion, grip strength, pain (visual analog scale), DASH scores, and radiographic alignment between cohorts. A Chi-squared analysis was used to determine radiographic differences of arthritis.

Results

There were no significant differences in mean range of motion, grip strength, Quick DASH score, Mayo wrist score, pain level, or radiographic arthrosis between cohorts. There was no correlation between radiographic signs of osteoarthritis and the QuickDASH score, and pain level.

Conclusion

The outcomes of intraarticular fractures of the distal radius with operatively treated associated SLI are comparable with the outcomes of intraarticular fractures of the distal radius without associated SLI.

Functional outcomes and complications after treatment of distal radius fracture in patients sixty years and over: A systematic review and network meta-analysis

AimThis network meta-analysis aims to compare functional outcomes and complications between conservative treatment and surgery for distal radius fractures in patients aged 60 years and over.MethodsWe searched the PubMed, EMBASE, and Web of Science databases for randomized controlled trials (RCTs) assessing the effect of conservative treatment and surgery for distal radius fractures in patients aged 60 years and over. Primary outcomes included grip strength and overall complications. Secondary outcomes included Disabilities of the Arm, Shoulder, and Hand (DASH) scores, Patient-Rated Wrist Evaluation (PRWE) scores, wrist range of motion and forearm rotation, and radiographic assessment. All continuous outcomes were assessed using standardized mean differences (SMDs) with 95% confidence intervals (CIs), and binary outcomes were assessed using odds ratio (OR) with 95% CIs. The surface under the cumulative ranking curve (SUCRA) was used to determine a hierarchy of treatments. Cluster analysis was performed for grouping treatments based on the SUCRA values of primary outcomes.ResultsFourteen RCTs were included to compare conservative treatment, volar lockedplate (VLP), K-wires fixation, and external-fixation. VLP outperformed conservative treatment for 1-year and minimum 2-year grip strength (SMD; 0.28 [0.07 to 0.48] and 0.27 [0.02 to 0.53], respectively). VLP yielded the optimal grip strength at 1-year and minimum 2-year follow-up (SUCRA; 89.8% and 86.7%, respectively). In a subgroup analysis of patients aged 60 to 80 years old, VLP outperformed conservative treatment in DASH and PRWE scores (SMD, 0.33 [0.10, 0.56] and 0.23 [0.01, 0.45], respectively). In addition, VLP had the fewest complications (SUCRA = 84.3%). Cluster analysis suggested that VLP and K-wire fixation were more effective treatment groups.ConclusionEvidence to date demonstrates that VLP provides measurable benefits in grip strength and fewer complications to those 60 years of age and over, and that benefit is not reflected in current practice guidelines. There is a subgroup of patients where K-wire fixation outcomes are similar to those of VLP; defining this subgroup may yield substantial societal benefits.

Funktionelle Ergebnisse nach Radiuskorrekturosteotomie

BACKGROUND: Malunited fractures of the distal radius frequently show disabling and painful reductions in active range of motion (AROM) of the wrist and forearm with reduced grip strength. Shortening and three-dimensional torsion of the distal radius occur with relative ulnar lengthening. Corrective osteotomy of the distal radius is indicated in these conditions. METHODS: We examined 24 of 30 patients after corrective osteotomy with respect to AROM, grip strength, DASH, and pain perception (visual analogue scale). The mean age of the population was 49 years (18-69 years), and the mean follow-up period was 22 months (6-63 months). RESULTS: Preoperative extension/flexion was 65 degrees , postoperative 92 degrees (p<0.05). Forearm rotation improved from 129 degrees preoperative to 160 degrees postoperative (p<0.01). The DASH score could be reduced from 40 (n=9) to 18 (n=24). Grip strength increased from 17 kg to 27 kg postoperative (p<0.01). Radioulnar inclination increased from 15 degrees preoperative to 24 degrees postoperative (p<0.05). Relative ulnar lengthening could be minimized from 4.3 mm to 0.7 mm (p<0.05). CONCLUSION: Data show that reconstruction of the distal radius improves grip strength and range of motion significantly with simultaneous reduction of pain perception and DASH scores.
