The Die Punch Fragment: Analysis of Fragment Geometry and Need for Fixation.

Introduction Die punch (DP) fragments are among the most common fracture fragments to lose reduction after volar locked plating of articular distal radius fractures (DRFs). We aimed to report the number of patients in our institution who had a computed tomography (CT)-confirmed DP fragment and who had open reduction and internal fixation (ORIF) through a dorsal approach; to report the length of the radioulnar portion of the DP fragment relative to the total distal radioulnar joint (DRUJ) length; and to identify if an association exists between this length and the choice for a volar versus a dorsal operative approach to the DP fragment. Materials and Methods We performed measurements on the preoperative CT scans of 94 skeletally mature patients with a DP fragment. We also collected data related to their demographics, injury, and treatment. Of the 94 patients in this study, 84 (89%) had AO type C fractures. Results Thirteen out of 94 patients (14%) who had ORIF of their DRF with a DP fragment had a separate dorsal incision. The mean proportion of the DP fragment length relative to the total DRUJ length was 0.51 ± 0.19. There was no association between the length of the DP fragment and volar versus dorsal approach. Conclusion DP fragment size is not an indicator of the need for or use of a dorsal approach in DRF fixation. Level of Evidence This is a Level IV,-retrospective study.

Survival and Health-Related Quality of Life after Hospitalization for Necrotizing Soft Tissue Infections of the Upper Extremity: A Long-Term Outcome Study.

Introduction The main aim of the study was to investigate the survival and health-related quality of life (HRQoL) after hospitalization for necrotizing soft tissue infections (NSTIs) of the upper extremity. Materials and Methods A retrospective study with long-term follow-up of patients surviving NSTIs of the upper extremity was performed. Survival and HRQoL after hospital discharge were the primary outcomes. The HRQoL was measured using the 36-item Short Form (SF-36), EuroQoL-5D-5L (EQ-5D), Quick Disability of Shoulder, Arm and Hand (QuickDASH), and numeric rating scales (NRS) for satisfaction with appearance and pain. Results A median of 6.5 years after hospitalization, 81% of the 108 patients survived. The response rate was 45% ( n = 38). The SF-36 score was 80 (interquartile range [IQR]: 58-91), the EQ-5D score 1.4 (IQR: 1.2-2.2), the EuroQoL-Visual Analog Scale score 77 (IQR: 67-90), the QuickDASH score 13.6 (IQR: 2.3-30.7), the NRS for satisfaction with appearance 8 (IQR: 7-9), and NRS for pain 1 (IQR: 0-5). Conclusion Six-and-a-half years after the NSTI, 81% of the patients were still alive. General health prior to the NSTI mainly influenced the risk at secondary mortality. In surviving patients, the HRQoL varied widely, but was adversely affected by female sex, intravenous drug use, NSTI type I or III, and longer length of hospital stay.

MRI Findings in Patients Undergoing Triangular Fibrocartilage Complex Repairs Versus Patients Without Ulnar-Sided Wrist Pain.

Background: The clinical picture of ulnar-sided wrist pain is oftentimes confusing because various pathologies may be coexistent. In this study, we aimed: (1) to compare the prevalence of potential causes of ulnar-sided wrist pain on magnetic resonance imaging (MRI) in patients who underwent triangular fibrocartilage complex (TFCC) repair and control subjects: and (2) to evaluate whether inferior clinical results were associated with specific patient characteristics or other potential causes of ulnar-sided wrist pain. Methods: We included 67 patients who underwent a TFCC repair and 67 control subjects. The MRI scans were examined for sources of ulnar-sided wrist pain. After TFCC repair, 42 patients (63%) completed surveys, including Quick Disabilities of the Arm, Shoulder and Hand and pain scores. Bivariate analysis was performed to compare our groups and to identify factors associated with our outcomes. Results: We found significantly higher rates of distal radioulnar joint (DRUJ) arthritis (P = .033), extensor carpi ulnaris (ECU) pathology (P = .028), and ulnar styloid fractures (P = .028) in patients with TFCC repairs. With increasing age, increasing pathology in the pisotriquetral joint (P = .040), more ulnocarpal abutment (P = .0081), and more degenerative tears (P < .001) were seen in both groups. No demographic characteristics or MRI findings were significantly associated with our outcomes. Conclusions: We observed higher rates of DRUJ arthritis and ECU pathology in patients with TFCC tears undergoing repair compared with age- and sex-matched controls. This may be due to damage to the TFCC itself altering relationships of the DRUJ and the ECU subsheath, or it may reflect various pathologies that cause ulnar-sided wrist pain and drive patients toward surgery.

Predictors of Secondary Ulnar Shortening and Reoperation After Arthroscopic TFCC Debridement.

BACKGROUND: Predicting which patients will do well with arthroscopic triangular fibrocartilage complex (TFCC) debridement alone or which patients may benefit from arthroscopic debridement and ulnar shortening at the same time can be challenging. In this retrospective cohort study, we aimed to assess the rate and type of complications and reoperations after arthroscopic TFCC debridement. Furthermore, we aimed to identify factors associated with reoperation and specifically ulnar shortening osteotomy (USO) after this procedure. METHODS: We included 163 patients who underwent arthroscopic TFCC debridement as a first surgery for treatment of their ulnar-sided wrist pain. Patient charts were manually reviewed, and ulnar variance was measured on preoperative posteroanterior radiographs of the wrist. Bivariate analysis and multivariable logistic regression analysis were performed to identify factors associated with reoperation. Additional subgroup analyses looking at USO after TFCC debridement were performed with Kaplan-Meier analysis and Cox regression survival analysis. RESULTS: We found a complication rate of 14% and a reoperation rate of 19% (most common USO with 10%). Chondromalacia was independently associated with reoperation. Forty percent of patients with a positive ulnar variance later proceeded to USO. A hazard ratio of 1.8 per millimeter of ulnar variance was found. CONCLUSIONS: Our data suggest that patients with a positive ulnar variance with frank chondral loss at the time of arthroscopic TFCC debridement may benefit from simultaneous USO.

An Economic Analysis of Direct Costs of Distal Radius Fixation and the Implications of a Disposable Distal Radius Kit.

OBJECTIVE: To assess the direct costs of distal radius fracture volar plate (VP) fixation and to create a model to examine the effect of these cost drivers. MATERIALS AND METHODS: Retrospectively, 744 distal radius fractures treated with open reduction and internal fixation (ORIF) were identified. The outcomes assessed included (1) the direct costs related to distal radius ORIF and (2) if a VP alone was amenable. Costs were represented as a cost ratio relative to the average cost of distal radius ORIF, where the average value is set as 1.0. Simulation models were run with all cost drivers (sex, age, open fracture, intra-articular fracture, and ancillary fixation) and with only ancillary fixation as a cost driver. RESULTS: The cost ratio ranged from 0.61 to 1.81 and ancillary fixation was associated with increased implant costs in multivariable analysis. In the simulations, the cost ratio ranged from 0.96 to 1.23 when all cost drivers were included and from 0.99 to 1.20 if only ancillary fixation was included as a cost driver, a reduction of the range by 22.2%. Older patients, females, closed fractures, and extra-articular fractures were more amenable to VP fixation alone. CONCLUSIONS: Eighty-three percent of the surgically treated distal radius fractures were treated with VP fixation alone. A disposable kit could help limit cost variance per case by roughly 22%, as only ancillary fixation varies these costs. Closed fractures and extra-articular fractures in older patients or female patients are more amenable to VP fixation alone. LEVEL OF EVIDENCE: Economic Level III.

Hemiresection Interposition Arthroplasty of the Distal Radioulnar Joint: A Long-term Outcome Study.

Background: The aim of this study was to assess factors associated with long-term patient-reported functional, pain, and satisfaction scores in patients who underwent (Bowers) hemiresection interposition technique (HIT) arthroplasty of the distal radioulnar joint (DRUJ). The secondary aims were to determine the complication and reoperation rates. Methods: A retrospective study with long-term follow-up of patients undergoing HIT arthroplasty was performed. Demographic, disease, and treatment characteristics were collected for the 66 included patients. Thirty-one patients completed all surveys, which were the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), our custom-made HIT arthroplasty questionnaire, Numeric Rating Scale (NRS) for pain, and NRS for satisfaction. The mean interval between surgery and follow-up by means of questionnaires was 8.6 ± 3.4 years. Results: The mean QuickDASH score was 31.0 ± 20.2. The mean score of the HIT arthroplasty questionnaire was 2 ± 2. The median NRS for pain was 1 (interquartile range [IQR], 0-3), and the median NRS for satisfaction was 9 (IQR, 8-10). The complication rate and reoperation rate were 14% and 8%, respectively. Conclusion: Overall, patients expressed satisfaction with HIT arthroplasty, despite a mean QuickDASH score of 31.0. In our cohort, patients with inflammatory arthritis had higher satisfaction and lower pain scores. Patients who had prior trauma, prior surgery, or DRUJ subluxation are generally less satisfied. Men, older patients, and posttraumatic patients had higher long-term pain scores; however, posterior interosseous nerve neurectomy is associated with improved pain scores. Our findings support the use of HIT arthroplasty in patients with inflammatory arthritis.

A Comparative Study Between Darrach and Sauvé-Kapandji Procedures for Post-Traumatic Distal Radioulnar Joint Dysfunction.

Background: There are various treatments for post-traumatic distal radioulnar joint (DRUJ) dysfunction. The present study aimed to assess differences in long-term patient-reported outcomes on physical function, pain, and satisfaction between the Darrach and Sauvé-Kapandji procedures. Secondary aims were to describe the radiographic outcomes and to assess the difference in rate and type of complications and reoperations between these 2 procedures. Methods: We retrospectively analyzed 85 patients who had a post-traumatic DRUJ derangement and had been treated by either a Darrach (n = 57) or Sauvé-Kapandji procedure (n = 28). Fifty-two patients (61%) completed patient-rated outcomes surveys at a median of 8.4 years after their procedure. Radiographic measurements consisted of ulnar distance, radioulnar distance, and ulnar gap (only in Sauvé-Kapandji group). Results: There were no significant differences in Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Function score, pain score, satisfaction score, complications, and reoperations between patients who had a Darrach procedure or a Sauvé-Kapandji procedure. Seventeen patients (30%) in the Darrach group experienced a complication, and 14 patients (50%) in the Sauvé-Kapandji group experienced a complication (P = .09). The most common complication was instability of the ulnar stump (n = 10), followed by symptoms of the dorsal sensory branch of the ulnar nerve (n = 8). Patients who underwent a Sauvé-Kapandji procedure had more reoperations for excision of heterotopic ossification. Conclusions: Darrach and Sauvé-Kapandji procedures show comparable long-term patient-reported outcomes in treatment of post-traumatic DRUJ dysfunction. Complication and reoperation rate are relatively high, with non-significant differences between the 2 procedures.

Long-Term Results of Pisiformectomy in a Cohort of 57 Patients.

Background Excision of the pisiform is an infrequently used option for pisotriquetral joint dysfunction when nonoperative treatment is ineffective. This study reviews the patient-reported outcomes of patients treated with pisiformectomy, and furthermore focuses on the complications and the need for and time to revision procedure. Materials and Methods Medical records of 57 patients were manually reviewed and assessed for complications, rate of unplanned reoperations, and type of reoperations. Thirty-seven patients (65%) completed patient-rated outcomes surveys at a median of 10 years after their procedure. Results The complication rate was 13% ( n = 7). Ulnar nerve symptoms were noted in three patients. No reoperations were performed after the pisiform excision. Out of the 16 patients who had preoperative symptoms of ulnar nerve compression at the wrist, 10 patients reported that their symptoms had completely resolved after the surgery. The median Quick Disability of Arm, Shoulder and Hand (QuickDASH) score after surgery was 4.5 (2.3-16), median score for pain 0 (interquartile range [IQR]: 0-2), and median score for overall satisfaction 10 (IQR: 8-10). Conclusions Pisiformectomy is a surgery used sparingly in cases with refractory pain associated with arthrosis of the pisotriquetral joint or enthesopathy of the flexor carpi ulnaris/pisiform interface. When utilized in this fashion, patients report limited disability on patient-rated outcome measures, low pain scores, and high satisfaction at mid- to late follow-up.

Carpometacarpal 4/5 Fracture Dislocations: Fracture Morphology and Surgical Treatment.

We conducted a retrospective review of six patients with carpometacarpal (CMC) ⅘ fracture-dislocations managed with ORIF by a single surgeon between October 2006 and August 2017. An open, dorsal approach to the hamate was used with a combination of interfragmentary screw fixation and Kirschner wire reduction in the CMC joints. At a mean of 96 days follow-up (range: 31-265), all patients had recovered wrist motion, excellent grip strength, and complete resolution of pain. There were no complications or reoperations during the postoperative period. Radiographic review showed restoration of anatomy and well-maintained congruity of the CMC joints. Our study has shown favorable outcomes after open reduction and internal fixation of the hamate body fracture with interfragmentary screws, when combined with stabilization of the CMC dislocation with percutaneous Kirschner wires. Fracture morphology does not appear to guide choice for specific hardware (size screw, headed/headless) or use of a washer. This is a level IV, therapeutic study.

The Serially-Operated Essex-Lopresti Injury: Long-Term Outcomes in a Retrospective Cohort.

Objective The main aim of this article is to report 10-year outcomes after Essex-Lopresti injury (ELI). Study Design Retrospective case series. Two level I trauma centers and one associated community hospital from 2003 to 2016. Patients Sixteen patients who sustained an ELI and were treated at one of our three regional hospitals. Intervention Initially, 4 patients (25%) were treated nonoperatively by immobilization and 12 patients (75%) were treated operatively. Proximal surgery included radial head open reduction and internal fixation (ORIF), radial head arthroplasty, radial head excision and forearm ORIF, and wound debridement. Ten patients (63%) were acutely identified with longitudinal forearm instability. Of these, four patients had the distal radioulnar joint pinned. In the other six patients, the forearm was immobilized. Overall, 16 patients underwent a total of 32 revision surgeries. Main Outcome Measure Performance of Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) Physical score, Numeric Rating Scale (NRS) score for pain-severity, and NRS score for satisfaction of overall outcome. Results Follow-up for outcome evaluation was available for 10 patients, at a median of 10 (interquartile range [IQR]: 8.0-12) years after date of injury. The median PROMIS UE Physical score was 36 (IQR: 33-38). Median NRS score for pain-severity on average was 5 (IQR: 0-6). The median NRS score for satisfaction of overall outcome was 7 (IQR: 5-8). Conclusion Patients who sustain an ELI generally have substantial deficits of upper extremity function as measured by PROMIS UE. Early radial head arthroplasty may be beneficial, but further study in a larger cohort is needed. Outcomes of nonoperative treatment and operative treatment were similar and suggest that current surgical treatments are incomplete.

Nonunion and Reoperation After Ulna Shortening Osteotomy.

Background: The primary purpose of our study was to identify factors associated with reoperation after ulna shortening osteotomy. Our secondary aims were to determine the rate and type of reoperation procedures. Methods: In this retrospective study, we included patients older than 18 years of age who underwent an ulna shortening osteotomy between January 2003 and December 2015. Medical records of patients were assessed for our explanatory variables, reoperations, and reporting of symptoms. We used bivariate and multivariable analyses to identify factors associated with reoperation after ulna shortening osteotomy. Results: Among 94 patients who underwent 98 ulna shortening osteotomies, there were 34 reoperations (35%). Nineteen patients (19%) underwent removal of hardware, 6 (6.1%) had a nonunion, and 9 (9.2%) underwent additional surgeries. Surgery on their dominant limb, trauma, and prior surgery to the ipsilateral wrist were associated with reoperation. In multivariable analysis, factors independently associated with reoperation were the dominant side being affected (odds ratio = 3.9; 95% confidence interval [CI] = 1.36-11) and traumatic origin (odds ratio = 3.4; 95% CI = 1.1-11). Bivariate analysis identified younger age and prior surgery of the affected wrist as factors associated with hardware removal. More operations for refixation due to nonunion of osteotomy were performed in patients with a transverse osteotomy compared with patients with an oblique osteotomy. Conclusions: One in 3 patients will undergo a reoperation after ulna shortening osteotomy, most often due to hardware irritation or nonunion of osteotomy. Awareness of these rates and predictive factors may be helpful for preoperative discussions and surgical decision making.

Long-Term Outcomes After Extensor Carpi Ulnaris Subsheath Reconstruction With Extensor Retinaculum.

This study assessed the long-term outcomes and complications of patients that underwent operative treatment for extensor carpi ulnaris subluxation. Fifteen patients underwent extensor carpi ulnaris subsheath reconstruction at a median of 5.9 weeks nonoperative treatment interval (interquartile range: 2.4 to 13). Reconstruction consisted of using the extensor retinaculum as a sling reconstruction. We found that about 1 in 3 patients had a complication or reoperation. At a median of 8 years follow-up, many patients had some residual symptoms, but in general, most patients were satisfied.

Factors Associated with Mortality and Amputation Caused by Necrotizing Soft Tissue Infections of the Upper Extremity: A Retrospective Cohort Study.

BACKGROUND: It is unclear what the exact short-term outcomes of necrotizing soft tissue infections (NSTIs), also known and necrotizing fasciitis of the upper extremity, are and whether these are comparable to other anatomical regions. Therefore, the aim of this study is to assess factors associated with mortality within 30-days and amputation in patients with upper extremity NSTIs. METHODS: A retrospective study over a 20-year time period of all patients treated for NSTIs of the upper extremity was carried out. The primary outcomes were the 30-day mortality rate and the amputation rate in patients admitted to the hospital for upper extremity NSTIs. RESULTS: Within 20 years, 122 patients with NSTIs of the upper extremity were identified. Thirteen patients (11%) died and 17 patients (14%) underwent amputation. Independent risk factors for mortality were an American Society of Anesthesiologists (ASA) classification of 3 or higher (OR 9.26, 95% CI 1.64-52.31) and a base deficit of 3 meq/L or greater (OR 10.53, 95% CI 1.14-96.98). The independent risk factor for amputation was a NSTI of the non-dominant arm (OR 3.78, 95% CI 1.07-13.35). Length of hospital stay was 15 (IQR 9-21) days. CONCLUSION: Upper extremity NSTIs have a relatively low mortality rate, but a relatively high amputation rate compared to studies assessing NSTIs of all anatomical regions. ASA classification and base deficit at admission predict the prognosis of patients with upper extremity NSTIs, while a NSTI of the non-dominant side is a risk factor for limb loss.

What Role Does Positive Psychology Play in Understanding Pain Intensity and Disability Among Patients with Hand and Upper Extremity Conditions?

BACKGROUND: A large body of research shows that psychologic distress and ineffective coping strategies substantially contribute to more severe pain and increased physical limitations among patients with orthopaedic disorders. However, little is known about the relationship between positive psychology (constructs that enable individuals to thrive and adapt to challenges) and pain and physical limitations in this population. QUESTIONS/PURPOSES: (1) Which positive-psychology factors (satisfaction with life, gratitude, coping through humor, resilience, mindfulness, and optimism) are independently associated with fewer upper-extremity physical limitations after controlling for the other clinical and demographic variables? (2) Which positive-psychology factors are independently associated with pain intensity after controlling for relevant clinical and demographic variables? METHODS: In a cross-sectional study, we recruited patients presenting for a scheduled appointment with an orthopaedic surgeon at a hand and upper-extremity clinic of a major urban academic medical center. Of 125 approached patients, 119 (44% men; mean age, 50 ± 17 years) met screening criteria and agreed to participate. Patients completed a clinical and demographic questionnaire, the Numerical Rating Scale to assess pain intensity, the Patient-reported Outcomes Measurement Information System (PROMIS) Upper Extremity Physical Function computerized adaptive test to assess physical limitations, and six measures assessing positive-psychology constructs: The Satisfaction with Life Scale, the Gratitude Questionnaire, the Coping Humor Scale, the Brief Resilience Scale, the Cognitive and Affective Mindfulness Scale-Revised, and the Life Orientation Test-Revised. We first examined bivariate associations among physical limitations, pain intensity, and all positive-psychology factors as well as demographic and clinical variables. All variables that demonstrated associations with physical limitations or pain intensity at p < 0.05 were included in two-stage multivariable hierarchical regression models. RESULTS: After controlling for the potentially confounding effects of prior surgical treatment and duration since pain onset (step1; R total = 0.306; F[7,103] = 6.50), the positive-psychology variables together explained an additional 15% (R change = 0.145, F change [5, 103] = 4.297, p = 0.001) of the variance in physical limitations. Among the positive-psychology variables tested, mindfulness was the only one associated with fewer physical limitations (ß = 0.228, t = 2.293, p = 0.024, 4% variance explained). No confounding demographic or clinical variables were found for pain intensity in bivariate analyses. All positive-psychology variables together explained 23% of the variance in pain intensity (R = 0.23; F[5,106] = 6.38, p < 0.001). Among the positive-psychology variables, satisfaction with life was the sole factor independently associated with higher intensity (ß = -0.237, t = -2.16, p = 0.033, 3% variance explained). CONCLUSIONS: Positive-psychology variables explained 15% of the variance in physical limitations and for 23% of the variance in pain intensity among patients with heterogenous upper extremity disorders within a hand and upper extremity practice. Of all positive-psychology factors, mindfulness and satisfaction with life were most important for physical limitations and pain intensity, respectively. As positive-psychology factors are more easily modifiable through skills-based interventions than pain and physical limitations, results suggest implementation of such interventions to potentially improve outcomes in this population. Skills-based interventions targeting mindfulness and satisfaction with life may be of particular benefit. LEVEL OF EVIDENCE: Level II, prognostic study.

Surgery for Symptomatic Neuroma: Anatomic Distribution and Predictors of Secondary Surgery.

BACKGROUND: Neuromas are caused by irregular and disorganized regeneration following nerve injury. Many surgical techniques have been described to address neuroma with varying success. The aim of this study was to evaluate predictive factors for secondary surgery after initial surgical intervention for symptomatic neuroma along with a description of the anatomical distribution of surgically treated symptomatic neuromas. METHODS: Five hundred ninety-eight patients with 641 neuromas that underwent primary surgery for neuroma were identified retrospectively. The diagnosis of neuroma was based on physical examination and patient history in the medical charts. Neuromas were treated by excision, implantation in muscle or bone, excision with direct neurorrhaphy with or without nerve grafting, or other treatments. RESULTS: The rate of secondary surgery for neuroma was 7.8 percent, and secondary operations were performed at a median of 16.1 months. Excision alone or excision with implantation into bone or muscle had higher rates of secondary surgery compared with excision and direct neurorrhaphy with or without nerve graft. Neuromas were located in the upper extremity (49.61 percent), lower extremity (46.65 percent), and the groin/trunk (3.74 percent). CONCLUSIONS: Symptomatic neuromas are located predominantly in the extremities, and surgery can improve pain, with low secondary surgery rates. Excision with direct neurorrhaphy with or without nerve grafting was associated with lower reoperation rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

[A man with multiple erythematous and hyperpigmented papules]. / Een man met erythemateuze, gehyperpigmenteerde papels.

A 25-year-old male patient developed multiple polycyclic papules after he had been involved in a bombardment in Syria and was hit by metal particles. We recognized the lesions as keloids, a fibroproliferative condition with abundant scar tissue. Our patient was treated with intralesional glucocorticoid injections and pressure therapy.
