Twenty-Year Experience With Primary Distal Radioulnar Joint Arthroplasty From a Single Institution

The use of implant arthroplasty in the distal radioulnar joint is increasing. Two main types of implants are commonly used, ulnar head prosthesis (UHP) and hemi or semi-constrained total distal radioulnar joint arthroplasty. The literature consists mainly of small patient series. The purpose of this study was to examine our long-term outcomes of distal radioulnar joint arthroplasty. Patient data were collected in a patient registry from 2000 to 2019. The follow-up included radiographic examination, physical examination, Mayo Wrist Scores, pain level, range of motion, and grip strength. Reoperations were recorded. The implants were a semi-constrained prosthesis and a metallic UHP. The mean age at surgery was 50 years. Patient demographics were similar, but the semi-constrained group had a higher preoperative percentage of instability (85 vs 52 percent). The median follow-up time was 30 months for the semi-constrained implants group and 102 months for the UHP group. A total of 53 primary semi-constrained total joint arthroplasties and 102 UHPs were included. The grip strength and Mayo Wrist Score improved for both the implant groups. Pain reduced in 76% of the patients. Supination improved for the semi-constrained total joint arthroplasty group. Lifting capacity was better in the semi-constrained total joint arthroplasty patients. The unadjusted reoperation rate was 23% for the semi-constrained implants group and 34% for the UHP group. Twenty-two implants were bilateral; these had comparable results to unilateral implants. Kaplan-Meier survival curves demonstrated 94% survival rate for the semi-constrained implants group and 87% survival for the UHP group after 5 years. The risk factors associated with reoperation for the combined implant group included younger age at surgery, previous wrist surgery, ulnar shortening, and wrist fusion. Distal radioulnar joint arthroplasty improved functional outcomes in both the implant groups, but reoperations were frequent. The semi-constrained implants group had better lifting capacity. The bilateral implants had comparable outcomes to the unilateral implants. Therapeutic IV.

Comparison of Clinical Outcomes in Open and Arthroscopically-Assisted Mini Open Proximal Row Carpectomy for Lichtman Stage IIIB and IIIC Kienböck Disease

Proximal row carpectomy (PRC) can be performed in the late stages of Kienböck disease using the traditional open technique or arthroscopically. In this study, we describe the arthroscopically-assisted mini-open PRC technique. The aim of the study was to compare the functional results with the open PRC technique in advanced-stage Kienböck disease. The medical records of patients with Kienböck disease who underwent open PRC between 2006-2010 (Cohort A) and arthroscopically-assisted PRC (AAPRC) between 2010-2018 (Cohort B) were analyzed. The Quick Disabilities of the Arm, Shoulder, and Hand scores, visual analog scale, and Modified Mayo Wrist Scores were compared, which were obtained at the early postoperative (third month) and final follow-up. Cohort A had 14 and Cohort B 21 patients. The preoperative, early, and final mean visual analog scale scores were 7, 3, and 0.3, respectively, for Cohort A, and 7, 0.3, and 0.1, respectively, for Cohort B. The preoperative mean Quick Disabilities of the Arm, Shoulder, and Hand scores decreased from 69 to 34 at the third-month and 6.1 on the final follow-up visit for Cohort A and from 77 to 18, and 5 for Cohort B. The final Mayo wrist scores were excellent in 4, good in 4, and moderate in 6 of the Cohort A patients, and excellent in 11, good in 8, and moderate in 2 of the Cohort B patients. Mean flexion increased to 52° from 43° for Cohort A and to 62° from 41° for Cohort B. AAPRC, compared to the open PRC, resulted in increased wrist motion and increased Mayo wrist scores in the long-term. Also, the third-month patient-related outcomes revealed favorable results in the AAPRC group. We attribute these findings to the earlier initiation of postoperative wrist motion and the less invasive character of the AAPRC procedure. Therapeutic IV.

Long-term outcomes after ulna shortening osteotomy: a mean follow-up of six years.

AimsThe primary aim of this study was to describe long-term patient-reported outcomes after ulna shortening osteotomy for ulna impaction syndrome.MethodsOverall, 89 patients treated between July 2011 and November 2017 who had previously taken part in a routine outcome evaluation up to 12 months postoperatively were sent an additional questionnaire in February 2021. The primary outcome was the Patient-Rated Wrist and Hand Evaluation (PRWHE) total score. Secondary outcomes included patient satisfaction with treatment results, complications, and subsequent treatment for ulnar-sided wrist pain. Linear mixed models were used to compare preoperative, 12 months, and late follow-up (ranging from four to nine years) PRWHE scores.ResultsLong-term outcomes were available in 66 patients (74%) after a mean follow-up of six years (SD 1). The mean PRWHE total score improved from 63 before surgery to 19 at late follow-up (difference in means (Δ) 44; 95% confidence interval (CI) 39 to 50; p = <0.001). Between 12 months and late follow-up, the PRWHE total score also improved (Δ 12; 95% CI 6 to 18; p = < 0.001). At late follow-up, 14/66 of patients (21%) reported a PRWHE total score of zero, whereas this was 3/51 patients (6%) at 12 months (p = 0.039). In all, 58/66 patients (88%) would undergo the same treatment again under similar circumstances. Subsequent treatment (total n = 66; surgical n = 57) for complications or recurrent symptoms were performed in 50/66 patients (76%). The most prevalent type of reoperation was hardware removal in 42/66 (64%), and nonunion occurred in 8/66 (12%).ConclusionUlna shortening osteotomy improves patient-reported pain and function that seems to sustain at late follow-up. While satisfaction levels are generally high, reoperations such as hardware removal are common.Cite this article: Bone Jt Open 2022;3(5):375–382.

Total Wrist Arthroplasty with Integra Freedom® Implants: A Pilot Study with a New Evaluation System.

Recent innovations in wrist arthroplasty implants have led to remarkable improvements in terms of results with improved stability and preservation of bone stock. Despite the advances in such implants, poor outcomes and frequent complications still affect this procedure, not allowing a wider use of this treatment in wrist arthritis.The purpose of this study is to assess the preliminary mid-term results of a Wrist Arthroplasty System (Freedom®, Integra Lifesciences, Princeton, USA) in patients with rheumatoid arthritis or secondary osteoarthritis of the wrist and to propose a new classification system. We examined 12 patients (7 with rheumatoid arthritis and 5 with secondary osteoarthritis of the wrist) who underwent total wrist arthroplasties performed by a single surgeon using the fourth-generation prosthesis. Pre- and post-operative pain on a visual analogue score, functional parameters measured with Mayo Wrist score, patient-rated wrist evaluation score, range of motion, and radiographic analysis were collected. At a mean follow-up of 48 (SD 16.9) months a significant improvement (p < 0.0001) of the mean visual analogue, Mayo and PRWE scores following total wrist arthroplasty was observed. Wrist movements improved significantly (p < 0.001). We achieved significant improvements in pain relief, performance, and satisfaction both in rheumatic and non-rheumatic patients, confirmed by our scoring system. Level IV, case series.

Analyzing Chronological Change in Postoperative Magnetic Resonance Imaging Results in Patients With Kienböck's Disease by Using an Original Grading System.

Background and objectiveSignal changes in MRI for Kienböck’s disease have only been qualitatively assessed so far. In light of this, we proposed a new grading system for quantitative analysis with an ordinal scale.MethodsThe study included 31 patients (17 men, 14 women) with Kienböck's disease. By referring to Nakamura’s MRI grading system, we devised a grading system with five grades (Grades 1-5) using proton density-weighted (PDW) coronal images with respect to the signal intensity of the lunate. All cases were examined by using the MRI grading system by three hand surgeons, both preoperatively and postoperatively. We evaluated the inter-rater reliability of our grading system by using the interclass correlation coefficient. After surgery, we implemented annual MRI evaluation for as long as possible and quantitatively assessed changes in MRI grades. We also investigated the correlation between postoperative MRI grades, Mayo Wrist Scores (MWS), and age at the surgery by using Pearson’s coefficient.ResultsThe MRI evaluation was performed 2-15 years after surgery. The reliability of our grading system was high; inter-rater interclass correlation coefficients were 0.783 (examiners 1-2), 0.780 (examiners 1-3), and 0.825 (examiners 2-3), representing a substantial agreement. The correlation coefficient between the MRI grade and MWS was -0.31, suggesting a mild negative correlation; postoperative MRI grade also correlated with age at surgery (Pearson’s coefficient: 0.447).ConclusionsOur proposed MRI grading system has high reliability and could be used to assess the regeneration of a necrotic lunate for quantitative analysis on an ordinal scale. Improvements were observed one to four years postoperatively, demonstrating a mild correlation with the clinical results.

Did implementation of three ligament tenodesis improve patient outcome after chronic scapholunate instability? A retrospective study.

Scapholunate instability frequently leads to chronic pain or even severe osteoarthritis of the wrist. Most favored reconstruction techniques of chronic SL-ligament injuries are based on the usage of a tendon, although there is still a lack of consensus which technique is superior. In a retrospective cohort analysis we compared 9 patients who underwent SL-ligament repair according to Van den Abbeele and 12 patients who underwent modified three ligament tenodesis according to Garcia-Elias, performed at a single institution. Follow-up of Van den Abbeele group was 36-120months and 13-39months in the Garcia Elias cohort. Although both techniques showed good functional outcome in most cases, modified three ligament tenodesis seemed to be advantageous regarding wrist range of motion (162°) compared to Van den Abbeele cohort (87°). Moreover, pain score showed significant differences between the two cohorts during follow up (VAS Van den Abbeele 4.2; VAS Garcia Elias 1.7). Interestingly, DASH-score (16.1 Van den Abbeele; 16.8 Garcia Elias) and modified mayo wrist score (72 Van den Abbeele; 69 Garcia-Elias) did not show any differences between the two patient cohorts. Via implementation of modified three ligament tenodesis as a standard of care for our patients we could improve the functional outcome after SL-ligament injuries and effectively decrease postoperative pain.

Two Parallel Headless Compression Screws for Scaphoid Fractures: Radiographic Analysis and Preliminary Outcome.

Despite surgical fixation, the scaphoid nonunion rate remains at 3% to 5%. Recent biomechanical studies have demonstrated increased stability with 2-screw constructs. The objective of our study is to determine the preliminary union rate and anatomic feasibility of 2-screw surgical fixation for scaphoid fractures. This study is a retrospective case series of 25 patients (average age 32 years) with scaphoid fractures treated with 2 parallel headless compression screws (HCS). Postoperative evaluation included Mayo Wrist Score (MWS), range of motion, time to union, and return to activity. Bivariate analysis for gender and Pearson correlation coefficient for body size (height, weight, and body mass index) was conducted against radiographically measured scaphoid width, screw lengths, and the distance between the 2 screws. All fractures healed with an average time to union of 9.9 weeks (median 7.6 weeks; range: 4.1-28.3). The mean MWS was 93.3 (range: 55-100), with 3 complications (12%), one of which affected the outcome of the surgery. The bivariate analysis demonstrated that the female gender was associated with significantly smaller scaphoid width (P = .004) but a similar distance between the 2 screws (P = .281). The distance between the 2 screws and the body size demonstrated a weak-to-no correlation. The 2-screw construct for scaphoid fracture achieved a favorable union rate and clinical outcome. Gender was the only variable significantly associated with scaphoid width and screw length. The distance between the screws was constant regardless of gender and body size, indicating that the technique for parallel screw placement can remain consistent. Therapeutic. Level IV.

Effect of Rehabilitation Robot Combined with Upper Limb Rehabilitation Training on Hemiplegic Patients in Recovery Stage of Stroke

<bold>Objective:</bold> To observe the effect of upper limb rehabilitation robot combined with upper limb rehabilitation training on motor function of upper extremity of hemiplegic patients in recovery stage of stroke. <bold>Methods</bold> A total of 40 hemiplegic patients in recovery stage of stroke who were treated in the Zhujiang Hospital of Southern Medical University from October 2018 to January 2020, which were randomly divided into the control group and the observation group according to the random number table method, with 20 cases in each group. Both groups received basic medication and conventional rehabilitation therapy (including good limb position, active and passive joint movement, sitting and standing balance training, walking function training, assistive device use training, speech and swallowing therapy, conventional physical therapy, etc.). The control group received upper limb rehabilitation training on the basis of basic medication and conventional rehabilitation therapy, 60 minutes a time, once a day, seven days a week, continuous treatment for two weeks. The observation group received upper limb rehabilitation robot training on the basis of the control group, upper limb rehabilitation training for 30 minutes a time, upper limb robot rehabilitation training for 30 minutes a time, once a day, seven days a week, continuous treatment for two weeks. Before and after treatment, the Fugl-Meyer assessment-upper limb (FMA-UL) was used to evaluate the motor function of upper extremity, including the FMA shoulder and elbow (FMA-SE) score and the FMA wrist and hand (FMA-WH) score; the Barthel index (BI) was used to evaluate activities of daily living; the root mean square (RMS) and integral electromyography (iEMG) values of the biceps, triceps, deltoid of anterior and middle fiber of the affected upper limbs of the subjects during maximal isometric contraction were measured by surface electromyography to assess muscle activation and synchronization of motor recruitment of the upper limbs. <bold>Results</bold> A total of 38 hemiplegia patients in the recovery stage of stroke completed the whole course of treatment. Compared with before treatment, FMA-UL score, FMA-SE score, FMA-WH score, BI score, RMS values of biceps, triceps, deltoid of anterior and middle fiber, and iEMG values of the both groups after treatment were significantly higher, with statistically significant differences (<italic>P</italic>&lt;0.05). Compared with the control group, the FMA-UL score, FMA-SE score, BI scores, triceps RMS value, deltoid of middle fiber RMS value and iEMG value of observation group were significantly higher, with statistically significant differences (<italic>P</italic>&lt;0.05). <bold>Conclusion</bold> Upper limb rehabilitation robot combined with upper limb rehabilitation training can effectively improve motor function of upper limb, muscle activation and motor unit recruitment synchronization of hemiplegic upper limb, and improve the activities of daily living of hemiplegic patients in recovery stage of stroke, which is worthy of clinical promotion.

Trapeziectomy and Alternative Suspension Technique in Thumb Carpometacarpal Arthritis: Patient-Reported Outcome Measures

PurposeFor treatment of carpometacarpal thumb joint osteoarthritis, a trapeziectomy with an alternative suspension technique can be performed as the primary surgery or as the secondary after a failed primary surgery. This study evaluates the midterm follow-up (median, 54 months) for this technique using patient-reported outcome measures.MethodsAfter trapeziectomy, an alternative suspension technique is performed with a flexor carpi radialis tendon strip. Leaving the insertion intact, the strip is tunneled through a drill hole in the base of the first metacarpal and then through a drill hole in the second metacarpal neck and then sutured back onto itself. This suspends the first metacarpal to the shaft of the second metacarpal, creating a strong, V-shaped suspension. As the technique is performed in both the primary and secondary surgery, we analyzed both groups separately. As the primary outcome, we evaluated pain and function with the Patient-Rated Wrist and Hand Evaluation. Further, we evaluated the Disabilities of the Arm, Shoulder and Hand and Short Form 12 questionnaire scores from eligible patients. Finally, we correlated pain and function to quality of life.ResultsThe median Patient-Rated Wrist and Hand Evaluation score was 16.0 (interquartile range, 1.5–40.4) after the primary surgery and 46 (interquartile range, 34.0–75.5) after the secondary surgery. Patients after the primary surgery also scored better on the Disabilities of the Arm, Shoulder, and Hand questionnaire compared to patients after the secondary surgery. The Short Form 12 questionnaire physical scores were negatively correlated with the Disabilities of the Arm, Shoulder, and Hand questionnaire scores for the primary group (correlation coefficient, −0.468) and negatively correlated with the Patient-Rated Wrist and Hand Evaluation pain scores for the secondary group (correlation coefficient, −0.703).ConclusionsTrapeziectomy with this alternative suspension technique for treatment of carpometacarpal thumb joint osteoarthritis shows good patient-reported outcome measures for primary surgery and poor patient-reported outcome measures after the secondary surgery.Type of study/level of evidenceTherapeutic IV.

Elderly unstable distal radius fractures a prospective cohort study of bone substitutes-augmented percutaneous pinning

BackgroundBased on debatable recommendations of using bone substitutes for filling of metaphyseal void in elderly unstable distal radius fractures; this study investigated the following question “Do bone substitutes effectively contribute to postoperative stability of k-wire fixation construct and accelerate healing in elderly unstable distal radius fractures?”.MethodsThis prospective cohort study was conducted from October 2014 to April 2021. According to use of bone substitutes, 40 patients of elderly unstable distal radius fractures were alternately allocated into; group-(A) of bone substitutes-augmented percutaneous pinning (19 patients); and group-(B) of non-augmented percutaneous pinning (21 patients). Groups were compared for preoperative patients’ demographics and postoperative ROM, Quick-DASH and Mayo Wrist scores, radiographic parameters (palmar tilt, radial height and inclination, ulnar variance and intra-articular step-off) and duration until radiographic fracture healing.ResultsStatistically, augmented and non-augmented groups were matched in terms of patients’ demographics (mean age; 58.7 vs. 62.0 years respectively, P-value = 0.25). All included fractures have healed with insignificantly longer duration in augmented group (7.1 vs. 6.8 weeks, P-value = 0.26). At 12-week postoperative evaluation, radiographic parameters of both groups were comparably well-maintained except for intra-articular step-off which showed significantly less secondary displacement in augmented group (0.1 vs. 0.4 mm, P-value = 0.01). There were insignificant differences in 6-month postoperative ROM, and Quick-DASH and Mayo Wrist scores.ConclusionCompared to its bone substitutes-augmented counterpart; non-augmented percutaneous pinning of elderly unstable distal radius fractures can offer advantages of comparable healing rates and functional and radiographic outcomes, less-invasive approach, shorter operative time and lower cost.Level of evidenceIII

Reconstruction of scaphoid waist non-unions using a radial approach: Preliminary outcome analyses

This study aimed to evaluate clinical and radiographic outcomes in a consecutive series of patients who underwent open surgery via a radial approach for reconstruction of scaphoid waist non-union. Over a 2-year period, 16 males with scaphoid waist non-union received surgery using a radial approach; we performed limited styloidectomy, biconcave curettage, ovoid bone grafting from the styloidectomy fragment, and placement of a retrograde radial-entry screw. Mean patient age was 25.1 years (range 17–56 years). Bony union was determined on radiographs and computed tomography. Radiographic variables were measured on preoperative and final follow-up radiographs. Mean follow-up was 14 months (range 8–19 months). Subjective and objective outcomes were recorded. Radiographic healing was achieved in 14 of the 16 patients (88%) at a mean 4½ months after surgery (range 3–6 months). Significant postoperative improvements were found in mean carpal height ratio (from 0.48 to 0.53) and radiolunate angle (from 8.2° to 2.8°) compared to preoperative data. Mean postoperative wrist extension was 54° (range 32–67°) and mean flexion 49° (range 2–64°). Mean flexion arc after surgery was 84.1% that of the contralateral side. Mean grip strength was 85.2% that of the contralateral side. Subjective results comprised mean postoperative Modified Mayo Wrist score of 82.3 (range 55–90) and Quick Disabilities of the Arm, Shoulder and Hand score of 11.2 (range 0–36.4). Twelve of the 14 healed wrists were subjectively rated as good or excellent. Repair of scaphoid non-union via a radial approach was safe and effective. Union rates were high and outcomes were good.

Effect of the Articular Surface Incongruency on Surgical Outcome of the Distal Radius Fracture.

Purpose The aim of this study was to demonstrate the joint fragment that mostly affects the outcome of the distal radius fracture surgically treated with a volar locking plate (VLP). Methods The outcomes of 69 patients with the distal radius fractures were evaluated at their final follow-up. The articular surface was divided into six specific fragments, and computed tomography (CT) was used to evaluate the degree of mismatch of each fragments. A plain radiograph was also obtained for evaluation of the distal radius alignment. Clinical outcomes were measured by using the Disabilities of the Arm, Shoulder and Hand (DASH) and Modified Mayo Wrist Score (MMWS). Univariate analyses were performed, with subsequent multiple logistic regression analyses. Results The mean follow-up period was 14.8 (range, 12 to 52) months. The group with a worse DASH score showed significantly greater mismatch in the volar and dorsal lunate facets, as well as the central depression of the distal radius (p = 0.042, 0.031, and 0.023, respectively). There was a significant positive correlation between the DASH score and degree of mismatch of the dorsal lunate facet and central depression of the distal radius (p = 0.040 and 0.011, respectively). Groups with worse MMWS showed significantly greater mismatch in the dorsal lunate facet (p = 0.025). There was a significant negative correlation between MMWS and abnormal ulnar variance and mismatch of the dorsal lunate facet and central depression of the distal radius (p = 0.041, 0.004, and 0.018, respectively). The result of multiple logistic regression analysis demonstrated that a mismatch of the dorsal lunate facet is a significant predictor for a worse MMWS (odds ratio = 3.072, p = 0.043). Conclusions Articular surface mismatch of the dorsal lunate facet appears to mostly affect the surgical outcomes of the distal radius fractures using VLP. In cases where the dorsal lunate facet is heavily involved, surgeons should be cautious about its reduction and fixation.

Changes in wrist joint contact area following radial shortening osteotomy for Kienb\xf6ck\u2019s disease

We hypothesized that the contact area of the articular surface of the wrist joint could be evaluated using a custom-designed analytical program. The aim of the study was to compare the articular contact area of the wrist joint before and after radial shortening osteotomy for Kienböck’s disease. Nine wrists of 9 patients underwent radial shortening osteotomy for Kienböck’s disease. Computed tomography (CT) images of the wrist joint were reconstructed using a 3D reconstruction software package. Radioscaphoid and radiolunate joint contact areas and translation of the joint contact area from preoperative to postoperative were calculated using customized software. The mean Modified Mayo Wrist Score was significantly improved from 50.6 preoperatively to 83.3 at final follow-up (p < .001). Preoperatively, the pain was reported as severe in five wrists and moderate in four wrists, while at final follow-up, five patients were free from pain and four patients had mild pain with vigorous activity. The preoperative radioscaphoid joint contact area was 133.4 ± 49.5 mm2 and the postoperative radioscaphoid joint contact area was 156.4 ± 73.1 mm2. The preoperative radiolunate joint contact area was 194.8 ± 92.1 mm2 and the postoperative radiolunate joint contact area was 148.3 ± 97.9 mm2. The radial translation distance was 0.4 ± 1.2 mm, the dorsal translation distance was 0.6 ± 1.2 mm, and the proximal translation distance was 0.2 ± 0.4 mm. CT-based analysis revealed that the center of the contact area translated radially following radial shortening.

Mid- to long-term functional results after Bowers' hemiresection interposition arthroplasty of the distal radio-ulnar joint

Bowers' hemiresection interposition arthroplasty of the distal radio-ulnar joint has been performed for decades, mainly for the treatment of osteoarthritis of the distal radio-ulnar joint. However, long-term test results are sparse. Evaluation of a homogeneous patient population following a mid- to long-term postoperative follow-up interval after hemiresection interposition arthroplasty. Twenty-five patients were evaluated 77.2 (±34.6) months after surgical therapy with regard to range of motion, grip strength and pain level. The subjective and objective scores DASH (Disabilities of Arm, Shoulder, and Hand) and MMWS (modified Mayo Wrist Score) were collected. Wrist mobility is not worse than 10.4° in relation to all directions of wrist movement compared with the healthy opposite side. Coarse grip strength is reduced by an average of 5.8 kg compared with the opposite side. The pain level decreased on average from 8.2 preoperatively to 1.8 postoperatively. Postoperatively, 22 patients (88 %) had a stable distal radio-ulnar joint. At the time of follow-up DASH averaged 26.7 (±21.4) and the MMWS averaged 78 (±15.7). Hemiresection interposition arthroplasty is areliable and safe surgical technique with good subjective and functional outcomes in the mid- to long-term.

FIXATION OF FRACTURE SCAPHOID WITH HEADLESS COMPRESSION SCREWA PROSPECTIVE STUDY ASSESSING FUNCTIONAL OUTCOME

Introduction: Scaphoid fractures are among the most common injuries which are usually resulting from RTA, Accidental fall, Sports injury. The greatest problems for the orthopaedic surgeon to treating the unstable scaphoid fracture and the complications (persistent pain at wrist, non-union, hypertrophic scar) occur from Herbert screw xation that results in wrist strength. 25 patients were included in our study Material And Methods: from OCTOBER 2019 to APRIL 2021, with subsequent period of follow up of 6 months (OCTOBER 2021). 25 patients with scaphoid fracture treated by operative xation by Herbert screw. Regarding functional results, 24 case Results: s (96%) had no difculty doing day to day activity, in last follow up according to Modied Mayo Wrist Score. Regarding post-operative complications, Scar tenderness (2 cases, 8%) was seen and treated with local inltration of corticosteroids. One patient had developed cast failure and one patient had developed persistent pain. Conclusion: We have concluded that fractures of scaphoid when xed with headless compression screw shows excellent functional outcome.

Non-Displaced Scaphoid Waist Fractures: Percutaneous Screw Fixation Versus Cast Immobilization.

BackgroundScaphoid waist fractures make up 66% of scaphoid fractures and are mostly non-displaced. The purpose of this study was to demonstrate that percutaneous screw fixation is preferable to cast immobilization in the treatment of non-displaced or minimally displaced scaphoid waist fractures.MethodologyBetween 2017 and 2019, we conducted a retrospective review of patients aged 17-65 years who underwent treatment for acute non-displaced scaphoid waist fractures. In total, 52 patients with scaphoid waist fractures were included in the analysis, 25 of whom underwent percutaneous screw treatment and 27 were treated with a short plaster cast. Patient satisfaction, pain, range of motion, and grip strength were evaluated using the Mayo Modified Wrist Score (MMWS). In addition, the time to return to work/sports, union time, complications, and non-union status were evaluated.ResultsA total of 52 (35 male, 15 female) patients were enrolled in this study. The average follow-up time was 24.9 months (range, 24-29 months). The mean age was 28.12 years (range, 17-45 months). Group 1 consisted of 25 patients who underwent percutaneous screw fixation, and group 2 consisted of 27 patients who were treated with a short plaster cast. There were significant differences in return to work, return to sports, and union time between the two groups (p < 0.001). The sixth-month MMWS was significantly different between the two groups (p < 0.001), but the first-year MMWS was not significantly different between the two groups (p = 0.864). There were no complications in both groups.ConclusionsWith percutaneous screw fixation, acute non-displaced or minimally displaced scaphoid waist fractures demonstrated a high rate of union and early return to work/sports.

Outcomes following Distal Radioulnar Joint Arthroplasty in the Setting of Total or Partial Wrist Fusion.

Purpose To evaluate the functional outcome and complications following primary ulnar head or total distal radial ulnar joint (DRUJ) arthroplasty in patients who have a partial or total wrist fusion. Methods We conducted a retrospective review of 33 primary DRUJ implants in 31 patients who had a partial or total wrist fusion. Follow-up time averaged 67 months. There were 11 partial and 22 total wrist fusions with 22 ulnar head prosthesis and 11 total DRUJ implants. The mean age of the patients was 49 years. Eighty-one percent had previous surgeries with an average number of 4.6 previous wrist procedures. Pre- and postoperative pain levels were recorded. Mayo Wrist Scores were calculated. Grip strength, range of motion (ROM), and post-operative complications were noted. Results The pain scores improved in 67% of the patients. The Mayo Wrist Score improved significantly from a mean of 39 preoperatively to 51 postoperatively. The grip strength and pro-supination remained stable. The wrist ROM also remained stable in the patients with partial wrist fusions. During the follow-up period, 10 (30%) of the DRUJ implants were explanted, with a trend toward higher explantation rates in total wrist fusions with one in the partial fusion group and nine in the total wrist fusion group. Four of the explantations happened in the first postoperative year. Nineteen (61%) of the patients required a second surgery for a DRUJ implant-related complication; this rate was similar between the partial and total fusion groups. Conclusions DRUJ replacement resulted in improved pain scores and Mayo wrist scores in the majority of patients; however, the combination of primary DRUJ arthroplasty and total wrist fusion was associated with high complication rates. Surgeons should be aware of the high complication rate seen with DRUJ arthroplasty when combined with total wrist fusion.

Prospective Evaluation of Push-up Performance and Patient-Reported Outcomes Following Open Dorsal Wrist Ganglion Excision in the Active-Duty Military Population.

Background Dorsal wrist ganglia (DWG) are a common wrist pathology that affects the military population. This study prospectively evaluates push-up performance, functional measures, and patient-reported outcomes 6 months after open DWG excision in active-duty patients. Methods Twenty-seven active-duty patients were enrolled and 18 had complete follow-up. Included patients had DWG diagnosis, unilateral involvement, and no previous surgery. The number of push-ups performed within 2 minutes was measured preoperatively and at 6 months. Range of motion (ROM), grip strength, Pain Catastrophization Scale (PCS), Disabilities of the Arm, Shoulder, and Hand (DASH) score, Mayo Wrist Score, and visual analog scale (VAS) pain score were measured preoperatively and at 2 weeks, 6 weeks, 3 months, and 6 months. Results Push-up performance did not significantly change overall. Wrist flexion, extension, and radial deviation returned to preoperative ranges. Wrist ulnar deviation significantly increased from preoperative range. Grip strength deficit between operative and unaffected extremities significantly improved to 0.7 kg at 6 months from preoperative deficit of 2.7 kg. Mean scores significantly improved for the validated outcome measures-PCS from 6.3 to 0.67, VAS pain scores from 1.37 to 0.18, DASH scores from 12.8 to 4.3, and Mayo Wrist Scores from 80.3 to 89.4. No surgical complications or recurrences were reported. Conclusions Findings suggest that almost half of active patients may improve push-up performance after DWG excision at 6 months. Significant improvements were seen in wrist pain, ROM, grip strength, and all patient-reported outcomes, which is useful when counseling patients undergoing excision.

Dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments: A retrospective comparative study.

The aim of this study was to compare the outcomes of dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments. Thirty patients who underwent dorsal plating (Group A) (14 females, 16 males; mean age = 56.8 ± 10.1 years) and 28 who underwent volar plating with limited dorsal open reduction (Group B) (12 females, 16 males; mean age = 55.6 ± 17.7 years) for type C3 distal radius fractures with impacted articular fragments between 2006 and 2019 were retrospectively analyzed. The mean follow-up was 14.5 ± 3.2 months in group A and 13.2 ± 2.4 months in group B. The articular step-off, articular gap and joint penetration by screws on the computed tomography scans were used for radiologic evaluation. The functional outcomes were evaluated with range of motion, grip power, Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score, and Mayo wrist score. No significant difference was found in the step-off distance at 1 year after surgery between the two groups (P < 0.05). The ranges of extension, rotation, and radial and ulnar deviations did not differ between the groups. However, group B had a significantly higher range of flexion in the wrist joint than Group A (P = 0.010). The grip power, DASH score, and Mayo wrist score did not also differ between the groups. Implant removal owing to any discomfort at the operative site was performed in 15 patients (63%) in Group A and 7 patients (28%) in Group B. Similar clinical results can be obtained by both dorsal plating and volar plating with limited dorsal open reduction in treating type C3 distal radius fractures with impacted articular fragments. However, volar plating with limited dorsal open reduction can provide better wrist flexion with a low incidence of complications associated with implantation. Level III, Therapeutic Study.

Minimum 5-Year Outcomes of Dorsal Intercarpal Ligament Capsulodesis With Scapholunate Interosseous Ligament Repair for Subacute and Chronic Static Scapholunate Instability: A Clinical Series of 5 Patients

PurposeTreatment of subacute and chronic static scapholunate instability remains challenging. We aimed to determine 5- to 10-year outcomes of dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair for subacute and chronic static scapholunate instability.MethodsSix patients with subacute and chronic static scapholunate instability underwent dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair between 2011 and 2015, and 5 of them were followed for at least 5 years after surgery. The clinical and radiological results were retrospectively investigated. All patients were male, and the mean age at surgery was 37 years (range, 21–47 years). The mean period from injury to surgery was 26.2 months (range, 2–113 months). The surgical procedure was a modification of a method reported by Szabo et al.ResultsThe mean postoperative follow-up period was 8.1 years (range, 5.1–9.5 years). Median Disabilities of the Arm, Shoulder, and Hand and Mayo wrist scores improved from 23.3 to 1.7 and from 55 to 80, respectively, from before surgery to the final follow-up. Although the median flexion angle tended to be smaller, the median extension angle tended to be greater than before surgery. The median percent grip strength increased from 72.3% before surgery to 99.2% at the final follow-up. The median scapholunate gap improved from 4.2 mm before surgery to 2.1 mm at the final follow-up. The median scapholunate angle also improved from 95.7° before surgery to 71.3° at the final follow-up. Osteoarthritic changes were observed in 2 of 5 patients at the final follow-up.ConclusionsThe scapholunate gap in all patients was within the normal range after a mean of 8.1 years of follow-up. Dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair is considered a good alternative for subacute and chronic static scapholunate instability based on these 5- to 10-year outcomes.Type of study/level of evidenceTherapeutic IV.
