Less invasive surgery with wrist arthroscopy for distal radius fracture

Background

We developed a surgical procedure that can facilitate arthroscopic intervention for volar locking plate fixation for distal radius fracture (DRF) with a less invasive technique. This study is to investigate the effectiveness of our original procedure for the treatment of DRF.

Methods

One hundred fifty-five wrists of 153 consecutive patients underwent our original procedure: the plate presetting arthroscopic reduction technique (PART) for DRF. The fractures consisted of 37 extra-articular and 118 intra-articular fractures. The fractures were reduced, anatomical alignment was regained with the aid of an image intensifier, and the volar locking plate was preset. Wrist arthroscopy was then performed and the intra-articular condition assessed. If there were any residual dislocations of the intra-articular fragments, these were reduced arthroscopically, and soft tissue injuries were subsequently treated. The traction was then removed, and the plate was securely fixed. One hundred forty-five patients were followed up from 12 to 48 months. The final outcome was evaluated with the Mayo modified wrist score and Disability of the Arm, Shoulder and Hand questionnaire (DASH). The effectiveness of arthroscopy was also investigated.

Result

On arthroscopic inspection, intra-articular dislocations were found to be residual in 35.2 %, even if reduction seemed to have been achieved when viewed with the image intensifier. Scapholunate interosseous ligament injury was recognized in 28.9 %, and triangular fibrocartilage complex injury was observed in 63.2 %. The final outcome was 112 excellent, 31 good, and 2 fair. The mean DASH score was 4.1.

Conclusion

We developed the PART to simplify the combination of volar locking plating and arthroscopy. This technique was less invasive and effective in the treatment of DRF.     

Comparison of scapholunate distance measurements on plain radiography and computed tomography for the diagnosis of scapholunate instability associated with distal radius fracture

Purpose

To investigate radiographic criteria for scapholunate instability (SLI) in the setting of distal radius fracture (DRF) confirmed by arthroscopy.

Methods

Eighty-eight wrists with DRF treated by open reduction and internal fixation and assessed for SLI arthroscopically were evaluated. The scapholunate distance (SLD) was measured by preoperative posteroanterior wrist radiography and computed tomography (CT). SLD on radiographs was measured as the distance between the scaphoid cortex and the lunate cortex at the center of the scapholunate joint. SLDs were measured at the volar end (A1), center (A2), and dorsal end (A3) of the scapholunate joint on the central CT axial slice; and at the proximal end (C1), center (C2), and distal end (C3) of the scapholunate joint on the central CT coronal slice. Wrists were divided into three groups by arthroscopic assessments: stable (normal, Geissler grade 1 or 2), G3 (Geissler grade 3), and G4 (Geissler grade 4). SLD measurements on radiographs and CTs (A1–C3) were compared among the three groups. Receiver-operating characteristic (ROC) curve analyses were performed to evaluate the abilities of SLD measurements on radiographs and CTs to identify SLI in wrists with DRF. Interobserver and intraobserver reliabilities of SLD measurements on radiographs and CTs were analyzed by intraclass correlation coefficients (ICCs).

Results

SLDs of C3 differed significantly among the G3 and G4 groups, and among the stable and G4 groups. The area under the curve on ROC curve analysis was 0.855 for the SLD of C3, which was larger than that for SLD on radiographs. For C3, the intraobserver ICC was 0.832 and interobserver ICC was 0.73.

Conclusions

SLD at the distal end of the scapholunate joint on the central coronal CT slice was the most appropriate measurement for discrimination of Geissler grade 4 SLI in wrists with DRF.

Scapholunate dissociation associated with distal radius fractures

Objective

The exact prevalence of scapholunate dissociation (SLD) associated with distal radius fracture (DRF) and the effect of persistent SLD on the function of the wrist are not known. So, we examined the association between SLD and DRF and the effects of treatment on clinical outcomes.

Methods

Eight hundred and twenty-nine patients with 839 DRF were included in the study. The radiographs of the patients were examined with special reference to SLD both in pre- and post-reduction period. Persistent SLD cases were evaluated by the scoring system of Green and O’Brien at least 2 years after the fracture.

Results

Of the 839 fractures, 215 had SLD after the injury. When post-reduction radiographs were examined, SLD persisted in 98, but in 14 SLD was detected in the post-reduction period while not apparent in initial radiographs. So, a total of 112 patients (13.4 %) had persistent SLD. Nineteen patients were lost to follow-up and remaining 93 wrists examined clinically. Seventy-nine had pain on the scapholunate joint and 14 had not. When these patients were evaluated by Green and O’Brien system, symptomatic patients had fair or poor results but asymptomatic had good. The association between DRF and SLD is 13.4 %.

Conclusions

Severity of the distal radius fractures is not associated with SLD. Intra-articular fractures were associated with significant increase in the prevalence of SLD. In some cases, SLD may appear after reduction in distal radius. Most cases with SLD are symptomatic, and this may be the reason of poor cases following distal radius fracture.     

Begleitverletzungen distaler Radiusfrakturen

Background

Following treatment of distal radius fractures poor functional results can still be found despite satisfactory radiological findings. This may be due to concomitant carpal lesions occurring together with these fractures. The aim of this prospective study was to analyze the clinical outcome depending on the type of fracture and concomitant carpal lesions.

Patients and methods

A total of 66 patients with distal radius fractures treated over a 1-year period could be assessed. The functional results were compared with the uninjured contralateral side. The follow-up examination included patient history, physical and radiographic examination as well as the DASH (Disability of the arm, shoulder and hand) questionnaire and the modified Mayo wrist score.

Results

The average follow-up time was 12.7 months and the mean age of the examined patients was 53 years. The fracture classification according to AO (AO Working party for osteosynthesis questions) showed 32% type A, 10% type B and 58% type C fractures. In 55% a concomitant carpal lesion was found and 44% of the patients required surgical treatment. All fractures united without complications. In all cases X-rays showed no loss of reduction postoperatively. Overall grip strength and wrist motion was reduced to 81% compared to the uninjured side. Patients regained good function represented in a mean DASH score of 24.8 points and a Mayo score of 70.6 points. The number of complete intraarticular fractures (type C) was significantly higher in patients who needed surgical treatment for carpal lesions compared to the groups where concomitant carpal lesions did not require invasive treatment or those where no carpal lesions were found. However, due to the operative treatment a comparable functional result could be obtained in all groups independent of the injury severity.

Conclusions

The results demonstrate, if a correct restoration and surgical stabilization technique is used, clinical outcome following fractures of the distal radius also depends on an optimized management of concomitant carpal lesions.     

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 association of education level on outcome after distal radius fracture

Background

Socioeconomic factors have been found to be predictors of outcome for other ailments. The purpose of this study was to evaluate the association of patient education level on pain and disability after distal radius fracture.

Methods

A series of patients with distal radius fractures (n?=?335) were enrolled into a prospective research registry. Standard demographic information was obtained from patients, including a five-value categorical education variable. After treatment with closed reduction, external fixation, or internal fixation patients were evaluated for pain, function (Disability of the Arm, Shoulder, and Hand score [DASH]), range of motion (ROM), and grip strength at standard intervals until 12 months post-injury. A series of linear mixed effects models were developed to evaluate the relationship between time from injury and education level with each of the outcomes measured.

Results

Complete demographic and 12-month follow-up data were available on 227 patients (75 %). There were neither group differences in mode of injury, severity, nor treatment modality after stratification by education level. Mixed effects model analyses revealed a significant linear association between level of education and measured outcomes at each follow-up point. Overall, each increase in education level demonstrated a doubling of improvement in pain, ROM, grip strength, and DASH score.

Conclusions

Outcome of distal radius fracture depends on acute care and follow-up rehabilitation; however, patient-related factors indicative of socioeconomic status are becoming increasingly relevant as predictors of outcome and should be considered by the orthopaedist.     

Radiographic assessment of ligamentous injuries in distal radius fractures after open reduction and internal fixation

Objectives

Concomitant ligamentous injury in distal radius fractures (DRF) may explain continued pain following surgery. The purpose of this study was to compare radiographic measurements assessing scaphoid translation in DRF after reduction, to measurements performed on normal radiographs. This may allow noninvasive evaluation of radiocarpal ligamentous integrity.

Methods

Fifty postoperative radiographs were evaluated. The distance between the ulnar border of the radial styloid and the radial border of the scaphoid was measured midway between the styloid tip and scaphoid base, and then divided by scaphoid width at the same level. The measured ratios were compared to previously established normal data, established radiographic measurements of fracture reduction, fracture characteristics and fixation methods.

Results

Radiographic scaphoid position measurements differed significantly from normals (p = 0.0001). Fracture characteristics, surgical difficulty, and technique were not associated with scaphoid position.

Conclusions

Despite accurate surgical reduction, abnormal positioning of the scaphoid may persist. This may reflect ligamentous injury, which generates suboptimal clinical results. Identifying and addressing ligamentous injury during surgery may prevent the development of instability and improve outcome after DRF.     

Arthritis predicting factors in distal intraarticular radius fractures

Introduction

Intra-articular malunion with step off and gap formation is claimed to be crucial for radiocarpal degeneration. In addition to well-defined intraarticular malunion, the shape of the distal radius is important for unaffected wrist function. In typical intra-articular fracture patterns with a dorsoulnar and palmar ulnar fragment, alterations of the shape of the articular surface, in a kind of a cavity, without obvious step off can be observed. The aim of the present study is to determine the residual articular deformity following intra-articular radius fractures and to analyze their impact on the final clinical and radiological outcome.

Materials and methods

Eighty one patients with dorsally displaced distal intraarticular radius fractures were followed up for a mean period of 9 years. Surgical treatment of all patients included open reduction, plate fixation and corticocancellous bone grafting. Radiological measurements included palmar tilt, radial inclination and radial shortening as defined by ulnar variance, intra-articular Stepps and the measurement of the anteroposterior distance of the radial joint surface. Clinical assessment included active range of motion (ARM) of the wrist, pain according to a visual analogue scale (VAS), grip power, working ability, Disability of Arm, Shoulder and Hand Score (DASH Score).

Results

Articular malunion in the form of a cavity in the sagittal plane measured 4.8?mm, 1.3?mm more than on the non-injured side. Anteroposterior distance measured 20.6?mm, 2.1?mm more than on the non-injured side. Articular step-off and gap was noticed in 11 patients. At the final follow-up examination, there was a significant difference in articular cavity depth and the anteroposterior distance between arthritis stage I and II. Arthritis stage was associated with the range of motion (ROM) in the sagittal plane, but had no significant influence on the DASH, pain level, grip strength and ROM in the frontal plane.

Conclusion

ORIF leads to predictable results in the restoration of length and form of the distal radius. Increasing the articular cavity depth should be avoided to prevent degenerative arthritis at the radiocarpal joint at long-term follow-up visits.     

Functional outcome of arthroscopic assisted fixation of distal radius fractures

Background:

Many studies in literature have supported the role of wrist arthroscopy as an adjunct to the stable fixation of unstable intraarticular distal radial fractures. This article focuses on the surgical technique, indications, advantages, and results using wrist arthroscopy to assess articular reduction and evaluates the treatment of carpal ligament injuries and triangular fibrocartilage complex (TFCC) injuries in conjunction with the stable fixation of distal radial fractures.

Materials and Methods:

We retrospectively evaluated 27 patients (16 males and 11 females), who underwent stable fixation of intraarticular distal radial fractures with arthroscopic evaluation of the articular reduction and repair of associated carpal injuries. As per the AO classification, they were 9 C 1, 12 C2, 2 C3, 3 B 1, and 1 B2 fractures. The final results were evaluated by modified Mayo wrist scoring system. The average age was 41 years (range: 18-68 years). The average followup was of 26 months (range 24-52 months).

Results:

Five patients needed modification of the reduction and fixation after arthroscopic joint evaluation. Associated ligament lesions found during the wrist arthroscopy were TFCC tears (n=17), scapholunate ligament injury (n=8), and luno-triquetral ligament injury (n=1). Five patients had combined injuries i.e. included TFCC tear, scapholunate and/or lunotriquetral ligament tear. There were 20 excellent, 3 good, and 4 fair results using this score.

Conclusion:

The radiocarpal and mid carpal arthroscopy is a useful adjunct to stable fixation of distal radial fractures.     

Acute coronal plane scaphoid fracture and scapholunate dissociation from an axial load: a case report

Coronal fractures of the scaphoid are rare and can be difficult to diagnose. Axial load injuries that result in a complete coronal fracture of the scaphoid associated with an acute scapholunate dissociation are exceedingly rare. In our patient the radiographic finding of wide scapholunate dissociation was obvious; however, the coronal scaphoid fracture was not recognized initially nor suspected. During surgery the coronal scaphoid fracture was identified, reduced anatomically, and fixed with a compression screw. The scapholunate ligament also was repaired. A good result was obtained with return to sports with extension of 60 degrees and flexion of 70 degrees , grip strength equal to that of the uninjured wrist, and no radiographic problems (arthrosis, avascular necrosis, nonunion).

Does timing of surgery affect the outcome of open articular distal humerus fractures

Background

Open intraarticular distal humerus fractures classified as Orthopaedic Trauma Association (OTA) 13 C may have devastating consequences for patient’s quality of life, especially if leading arm in younger active patient is involved. We conducted a study to determine whether the timing of open reduction and internal fixation of open intraarticular distal humerus fractures affects the outcomes.

Patients and methods

Multicentric prospective study: In the first group, there were 15 patients, 10 men and 5 women, mean age 38.7 years, operated in <6 h of injury. In the second group 17 patients, 11 men and 6 women, mean age 42.3 years operatively treated in delayed settings, mean delay to operation 4.6 days of injury. In both groups, patients had open distal humerus articular metaphyseal multifragmentary fractures classified as OTA 13.C2 or 13.C3. Functional outcome was assessed with Mayo elbow performance score and Disabilities of Arm and Shoulder and Hand (DASH). Mean Mayo elbow performance (MEP) score in the first group was 71 (range 30–100); in the second, mean MEP was 64.3 (range 25–100). The mean DASH in the first group was 27.89 (range from 1.7 to 75.8), and in the second, mean DASH score was 32.6 (range 5.8–77.5). There were no statistically significant differences between two groups, MEP t(28) = 0.935, p < 0.358; DASH t(28) = ?0.636, p < 0.530.

Conclusion

Our study shows that early open reduction and internal fixation of open distal articular humerus fractures reduces the hospital stay, but does not significantly affect the overall outcomes and complications.     

Treatment of intraarticular middle phalanx fractures using the Ligamentotaxor®

Background

We evaluated the outcome of intraarticular middle phalanx fractures after dynamic treatment with the Ligamentotaxor® system.

Materials and methods

Ten consecutive patients (seven male, three female; mean age 52 years) with intraarticular middle phalanx fractures were treated with the Ligamentotaxor® between 2009 and 2011. Proximal interphalangeal joint mobility, grip strength and ‘Disabilities of the Arm, Shoulder and Hand’ (DASH) score were evaluated in a 15-month follow-up. The reconstitution of the intraarticular space was measured immediately after trauma, at 6 weeks and at 15 months by radiograph control. The severity of the trauma was classified according to AO.

Results

We found B1 30 %, C1 (Seno I + II) 50 % and C3 (Seno III–V) 20 %. In 60 % of the cases, fractures were localized on the middle base of the fifth digit, in 20 % on the third digit and in 20 % on the index finger. The dynamic treatment lasted 7 weeks; patients were exposed to full workload after 9 weeks. The mean flexion mobility after 15 months reached 73° (range 60–100°), and the extension deficit was 13° (range 0–20°) on average. Grip strength attained 71.3 % (range 60–87 %) of the contralateral side. Initial x-ray after trauma compared to the x-ray after 15 months showed an intraarticular space reconstitution average of 0.5 mm (range 0.1–0.9 mm) anterior–posterior and 0.6 mm (range 0.1–1 mm) lateral. Patients evaluated their outcome with an average of 14.6 points (range 3.3–26.7) using the DASH score.

Conclusion

Good results can be obtained with the Ligamentotaxor®. We recommend it for the dynamic treatment of intraarticular middle phalanx finger fractures. Larger series and long-term results are needed.     

Scapholunate instability after distal radius volar plating

Background

Prior to volar locked plating and early motion protocols, ligamentous injuries incidentally associated with distal radius fractures may have been indirectly treated with immobilization. Our goal was to determine the prevalence of scapholunate instability in our population, while identifying those who may have had progression of instability.

Methods

We retrospectively reviewed 221 distal radius fractures treated with a volar locking plate during a 6-year period. Average patient age was 59 years. Standard posteroanterior and lateral radiographs from the first and last postoperative visits were analyzed for scapholunate instability, using the criteria of scapholunate gap ≥3 mm and scapholunate angle ≥60°.

Results

Six patients (3 %) met neither or only one criterion for instability at the first postoperative visit and did not have ligament repair and then went on to meet both criteria at the last postoperative visit after an early motion protocol. Seven patients (3 %) met both criteria at the first and last postoperative visits and did not have ligament repair. Five patients (2 %) underwent primary scapholunate ligament repair at the time of distal radius fixation.

Conclusions

In our representative population, scapholunate instability was uncommon, either from initial injury or possible progression of occult ligament injury, despite early motion without operative treatment of the ligament. Thus, we did not find strong evidence for routinely delaying motion or pursuing further workup. When early radiographs clearly demonstrate acute scapholunate instability, more aggressive treatment may be appropriate for selected patients.     

Outcomes after radiocarpal dislocation: a retrospective review

Background

Radiocarpal dislocations are rare, high-energy injuries. High morbidity and poor functional outcomes are common. Currently, there is limited data on functional outcomes following treatment of this injury.

Methods

A retrospective review was conducted analyzing the radiographic and clinical outcome of patients treated for a radiocarpal dislocation from 1979 to 2010. Outcome assessments included wrist range of motion, grip strength, Mayo wrist score, patient-rated wrist evaluation (PRWE), and disabilities of the arm, shoulder and hand (DASH) score. Statistical analysis was performed with the Student’s t test.

Results

Twenty-six patients (26 wrists) were treated for a radiocarpal dislocation during the study period; 23 wrists were treated acutely (within 4 weeks of injury), and 3 were treated after a delayed presentation (>4 weeks). Clinical follow-up of more than 6 months was available in 17 patients. Three patients (12 %) underwent primary fusion as initial treatment (two radioscapholunate fusion; one total wrist fusion). Four wrists (24 %) failed initial treatment and were salvaged with scapholunate ligament reconstruction (one wrist) or partial wrist fusion (three wrists). Seventeen patients completed PRWE and DASH questionnaires with a mean of 14.6 years following surgery (range 2–32 years). Subjective outcomes tended to be superior in those patients treated with ligament reconstruction versus partial or complete wrist fusion; however, comparisons were not statistically significant.

Conclusion

Radiocarpal dislocations result in significant osseous and ligamentous injury to the distal radius and carpus. Early recognition and treatment of radiocarpal dislocations with open reduction, internal fixation, and repair of ligaments may result in improved long-term functional outcomes when compared to acute partial or complete wrist arthrodesis.     

Comparative study between trapezium resection and tendon interposition with and without ligamentplasty in the management of carpometacarpal arthrosis of the thumb

Purpose

Treating arthrosis in the base of the thumb has been a highly controverted subject. Many surgeries have been described, such as the isolated trapezium resection; resection with interposition with and without ligament plasty; arthrodesis, and arthroplasties. The purpose of this paper is to compare the two techniques which are currently the most used in this treatment.

Methods

A prospective study has been made to compare the surgical results between the trapezium resection with tendon interposition (tenoarthroplasty) — 22 cases — and tenoarthroplasty associated to ligament plasty—24 cases. Objective evaluation was done by measuring opponence, movements of the metacarpophalangeal joint, pinch and grasp strength, radiographic measurement of the distance between the base of first metacarpal and the scaphoid, and measurement of the angle between the first and the second metacarpals. Subjective evaluation was done with a DASH questionnaire, visual analog scale to evaluate pain and patient satisfaction.

Results and conclusion

After application of the criteria described and using Student ‘t’ tests for statistical analysis, the authors concluded that the ligament reconstruction has no advantage over the simple resection and tendon interposition in carpometacarpal arthrosis of the thumb.     

The impact of demographic factors and comorbidities on distal radius fracture outcomes

Background

Despite the prevalence and consequences of distal radius fracture (DRF), there is limited research that analyzes the effects of demographic factors and comorbidities as they relate to pain, perceived disability, and functional outcomes.

Methods

All data for this study were examined retrospectively within an established clinical database. Patients with DRF were evaluated during their first and final visits with a criterion-based numeric pain scale (CR12), the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire, and a global rate of change scale to assess outcomes of pain, perceived disability, and function, respectively.

Results

The number of days between injury and initial therapy evaluation were inversely correlated with changes in perceived pain and perceived disability (r?=??0.315, p?=?0.000; r?=??0.348, p?=?0.000). In addition, moderate and statistically significant correlations were noted between work status and average CR12 and DASH scores at final re-evaluation (r?=?0.392, p?=?0.000, r?=?0.473, p?=?0.000). No significant relationships were noted between additional demographic factors or comorbidities and pain, perceived disability, or function during statistical analysis.

Conclusions

Patients without diabetes, hypertension, or depression and those who were not smokers had better outcomes in terms of pain, perceived disability, and function in this study. In addition, earlier timing of initial evaluation after injury and full duty work status were significantly related to improvement in pain and perceived disability. Timing of initiation of therapy and return to work are suggested as avenues for future research.     

Early Outcomes of Scapholunate Injuries With Concomitant Distal Radius Fractures

Background: There is limited literature regarding the treatment of concomitant scapholunate ligament (SL) injuries in acute distal radius fractures (DRFs). We hypothesized that surgical treatment of SL injuries in adult patients with DRFs leads to improved functional outcomes. Methods: A retrospective review was made of 42 adult patients who underwent surgical treatment of a DRF with a SL injury between 2005 and 2013. In all, 39 of the 42 patients sustained an intra-articular DRF (AO B or C). SL injury was diagnosed by SL diastasis > 3 mm on posteroanterior (PA) radiographs, magnetic resonance imaging, or with wrist arthroscopy. Patients were divided into 3 groups: 23 had a SL repair and were treated within 21 days of injury (acute), 8 underwent SL repair greater than 21 days from injury (subacute/chronic), and 11 did not undergo repair (non-operative). Median overall time to clinical follow-up was 5.1 years. Mayo Wrist Scores (MWS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were used to evaluate functional outcome. Results: Clinical outcomes measured by the MWS at final follow-up (6 months-12 years) showed no significant differences between the 3 groups. Of patients treated acutely, 17.3% had good to excellent MWS. MWS at 1-year follow-up was 68.4, 70, and 64 in the acute, subacute/chronic, and non-operative groups, respectively. DASH scores were 16.7, 14.3, and 11.8 in the acute, subacute/chronic, and nonoperative groups, respectively, at a mean of 7.8 years. Conclusions: At mid-term follow-up, all 3 treatment groups had similar DASH scores to the general population. There were no statistical functional differences between any of the groups based upon MWS or DASH scores.
