Analysis of the relationship between shorter sleep duration and wrist fractures: based on NHANES.

BACKGROUND: Wrist fracture is one of the common limb fractures. Its incidence rate increases with age and osteoporosis. Nowadays, Sleep health is increasingly valued, but the relationship between wrist fractures and sleep time is not yet clear. METHODS: Data in this study were collected and screened from the NHANES from 2005 to 2010 and 2013 to 2014. The variables were extracted from interviews and compared between the wrist fractures and the sleep duration. The data was analyzed by weighted multivariate logistic regression. RESULTS: After excluding individuals who were not eligible and had invalid data, we finally identified 1835 participants for inclusion in this study. We found a negative association between the sleep duration and the fractured of the wrist (OR = 1.027,95% CI (1.027, 1.028), P < 0.00001). CONCLUSION: This study demons that the association between the sleep duration and the fractures of the wrist is significant. Our findings provide a better understanding of the relationship between sleep duration and wrist fractures. This study may help us reducing the incidence of wrist fractures in the population based on healthy sleep management in the future, and improve the quality of life of middle-aged and elderly patients. Provide evidence for clinical patients to manage healthy sleep.

Distinct patterns of fracture propagation in distal radial fractures and the relationship to the ulnar head.

BACKGROUND: The aim was to assess the direction of distal radius fractures and their relationship to the ulnar head. METHODS: We reviewed the 160 wrist radiographs. The fracture line was measured on the postero-anterior and lateral radiographs relative to the long axis of the forearm and the relationship to the ulnar head. FINDINGS: PA radiographs: the fracture line ran distal ulnar to proximal radial (ulnar to radial) in 11%, transverse in 74% and distal radial to proximal ulnar (radial to ulnar) in 16%. Lateral radiographs: the fracture line ran distal volar to proximal dorsal in 88%, transverse in two 1% and dorsal to volar in 11%. Radial shift (7.5%) only occurred with ulnar to radial or transverse fractures. The ulnar to radial fracture line started at the proximal end of the ulnar head/distal radio-ulnar joint in 88%. The radial to ulnar fracture line started ended a mean of 2.5 mm proximal to the distal radio-ulnar joint (p < 0.01). The transverse fracture line started at the base of the distal radio-ulnar joint in 53% and proximally in 47%. INTERPRETATION: There are two distinct coronal patterns: radial to ulnar ending c. 2 mm proximal to the distal radio-ulnar joint; ulnar to radial starting at the proximal distal radio-ulnar joint. There may be third pattern - transverse fractures; these may be variants of the above. Sagittally the main direction is volar to dorsal but 11% are obverse. This is the first description of distinct fracture patterns in extra-articular distal radius fractures. In addition the fracture patterns appear to correlate with different directions of force transmission which fit with our understanding of falling and the relatively uncontrolled impact of the wrist/hand with the ground. These patterns of fracture propagation help understand how the biomechanics of wrist fractures and may enable prediction of collapse.

Physical function trajectory after wrist or lower arm fracture in postmenopausal women: results from the Women's Health Initiative Study.

Long-term physical functioning trajectories following distal forearm fracture are unknown. We found that women with versus those without distal forearm fracture were more likely to experience a 5-year decline in physical functioning, independent of initial physical functioning level. This association was most evident among women 80 years and older. INTRODUCTION: Physical functioning trajectory following lower arm or wrist fracture is not well understood. PURPOSE: This study is to evaluate physical functioning trajectory before vs. after lower arm or wrist fracture, stratified by age. METHODS: We performed a nested case-control study of prospective data from the Women's Health Initiative Study (n = 2097 cases with lower arm or wrist fracture, 20,970 controls). Self-reported fractures and the physical functioning subscale of the RAND 36-item Short-Form Health Survey were assessed annually. We examined three physical functioning trajectory groups: stable, improving, and declining. RESULTS: Mean (SD) number of physical functioning measurements was 5.2 (1.5) for cases and 5.0 (1.4) for controls. Declining physical functioning was observed among 20.4% of cases and 16.0% of controls. Compared to women without lower arm or wrist fracture, women with lower arm or wrist fracture were 33% more likely to experience declining physical functioning (adjusted odds ratio [aOR] 1.33 95% confidence interval [CI] 1.19-1.49, reference group stable or improving physical functioning trajectory). Associations varied by age: age ≥ 80 years aOR 1.56 (95% CI 1.29-1.88); age 70-79 years aOR 1.29 (95% CI 1.09-1.52); age < 70 years aOR 1.15 (95% CI 0.86-1.53) (pinteraction = 0.06). Associations between lower arm or wrist fracture and odds of declining physical functioning did not vary by baseline physical functioning or physical activity level. CONCLUSIONS: Women with lower arm or wrist fracture, particularly those aged 80 and older, were more likely to experience declines in physical functioning than women without such fractures, independent of baseline physical functioning level.

Improved Outside-In Suture through the Joint Capsule to Repair the Palmer I-B Triangular Fibrocartilage Complex Superficial Injury.

BACKGROUND: The treatment of type I-B triangular fibrocartilage complex superficial injury is always a challenge to orthopedists. The traditional outside-in suture method often causes a risk of nervous irritation. We designed a modified outside-in suture through the joint capsule to repair the Palmer I-B triangular fibrocartilage complex superficial injury. METHODS: From December 2014 to December 2018, we retrospectively collected the medical records of 18 patients in our hospital who used the modified outside-in suture through the joint capsule to repair type I-B triangular fibrocartilage complex superficial injury. Among them, there were 12 males and 6 females, with an average age of 36.2 years. There were 6 cases on the left side and 12 cases on the right side. Record the healing time of all patients after surgery and the occurrence of related complications, and record the pain visual analogue scale (VAS), grip strength, wrist flexion and extension, radioulnar deviation and forearm rotation range of motion, modified Mayo wrist joint function score, and disability of arm-shoulder-hand (DASH) score before operation and at the last follow-up. RESULTS: One patient was lost to follow-up, and a total of 17 patients received the final follow-up. Patients were followed up for 24 to 36 months, with an average of 29.6 ± 3.0 months. No wound infection, nerve damage, or irritation occurred after the operation. At the last follow-up, 15 cases of wrist pain disappeared completely, and 2 cases had mild discomfort during exercise. At the last follow-up, VAS decreased from 3.8 ± 0.7 points before operation to 0.8 ± 0.7 points (P < 0.05); grip strength increased from 15.1 ± 3.1 kg before operation to 23.2 ± 1.5 kg (P < 0.05); wrist flexion and extension, radioulnar deflection, and forearm rotational mobility increased from 116.3 ± 2.2°, 37.0 ± 3.5°, and 141.6 ± 2.2° before operation to 117.2 ± 2.5° (P < 0.05), 38.9 ± 3.0° (P < 0.05), and 142.4 ± 1.9° (P < 0.05), respectively; the modified Mayo wrist joint function score increased from 66.1 ± 3.6 points to 82.5 ± 3.9 points (P < 0.05), of which 10 cases were excellent, 5 cases were good, 2 cases were fair, and the excellent and good rate was 88.2%; DASH score improved from 37.0 ± 5.7 points preoperatively to 8.0 ± 2.5 points (P < 0.05). CONCLUSION: The modified outside-in suture through the joint capsule to repair the superficial injury of Palmer I-B triangular fibrocartilage complex has a good clinical effect and is worthy of clinical widespread promotion.

Cost Analysis of Volar Plate Fixation Versus Plaster Cast Immobilization for Intra-Articular Distal Radial Fractures.

BACKGROUND: The aim of this study was to compare the cost-effectiveness and cost-utility between plaster cast immobilization and volar plate fixation for acceptably reduced intra-articular distal radial fractures. METHODS: A cost-effectiveness analysis was conducted as part of a randomized controlled trial comparing operative (volar plate fixation) with nonoperative (plaster cast immobilization) treatment in patients between 18 and 75 years old with an acceptably reduced intra-articular distal radial fracture. Health-care utilization and use of resources per patient were documented prospectively and included direct medical costs, direct non-medical costs, and indirect costs. All analyses were performed according to the intention-to-treat principle. RESULTS: The mean total cost per patient was $291 (95% bias-corrected and accelerated confidence interval [bcaCI] = -$1,286 to $1,572) higher in the operative group compared with the nonoperative group. The mean total number of quality-adjusted life-years (QALYs) gained at 12 months was significantly higher in the operative group than in the nonoperative group (mean difference = 0.15; 95% bcaCI = 0.056 to 0.243). The difference in the cost per QALY (incremental cost-effectiveness ratio [ICER]) was $2,008 (95% bcaCI = -$9,608 to $18,222) for the operative group compared with the nonoperative group, which means that operative treatment is more effective but also more expensive. Subgroup analysis including only patients with a paid job showed that the ICER was -$3,500 per QALY for the operative group with a paid job compared with the nonoperative group with a paid job, meaning that operative treatment is more effective and less expensive for patients with a paid job. CONCLUSIONS: The difference in QALYs gained for the operatively treated group was equivalent to an additional 55 days of perfect health per year. In adult patients with an acceptably reduced intra-articular distal radial fracture, operative treatment is a cost-effective intervention, especially in patients with paid employment. Operative treatment is slightly more expensive than nonoperative treatment but provides better functional results and a better quality of life.

Volar Plate Fixation Versus Cast Immobilization in Acceptably Reduced Intra-Articular Distal Radial Fractures: A Randomized Controlled Trial.

BACKGROUND: The evidence for the treatment of acceptably reduced intra-articular distal radial fractures remains inconclusive. We therefore compared the functional outcomes of cast immobilization (nonoperative) and volar plate fixation (operative) for patients with these fractures. METHODS: This multicenter randomized controlled trial enrolled patients between 18 and 75 years old with an acceptably reduced intra-articular distal radial fracture. Patients were randomized to nonoperative treatment or to operative treatment. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after 12 months. Secondary outcome measures were the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Short Form-36 (SF-36) questionnaire; a visual analog scale for pain; range of motion; grip strength; radiographic parameters; and complications. Analyses followed the intention-to-treat principle. RESULTS: A total of 96 patients were randomized, and 90 (46 in the nonoperative group and 44 in the operative group) were included in the analysis. Patients treated in the operative group had significantly better functional outcomes measured with the PRWE at 6 weeks, 3 months, 6 months, and 1 year. Additionally, a 28% rate of subsequent surgery was identified in the nonoperative group. CONCLUSIONS: Adult patients with an acceptably reduced intra-articular distal radial fracture have better functional outcomes for 12 months when treated operatively instead of nonoperatively. We therefore recommend surgical treatment for patients with these fractures. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Fracturas transversales del cuerpo del semilunar con retraso en la consolidación. Experiencia en el tratamiento artroscópico / Transverse fractures through the body of the lunate with delay in consolidation. Experience with arthroscopic treatment

ANTECEDENTES Y OBJETIVO: Las fracturas traumáticas del semilunar representan entre el 0,5% y el 1% de todas las fracturas del carpo. Las fracturas transversales del cuerpo del semilunar (tipo V) son las menos frecuentes y quirúrgicas si están desplazadas, porque tienen alto riesgo de necrosis o pseudoartrosis. El objetivo de este trabajo es presentar nuestra experiencia con el tratamiento artroscópico en pacientes con un retraso en la consolidación tras una fractura transversal del cuerpo del semilunar. MATERIAL Y MÉTODO: Presentamos dos casos clínicos de retardos de consolidación tras fracturas transversales del cuerpo del semilunar. RESULTADOS: En ambos casos no se diagnosticó la fractura con radiografía simple inicial y se determinaron mediante tomografía computarizada. En ambos casos se produjo un retraso en la consolidación. Se trataron mediante cruentación, aporte de injerto y osteosíntesis bajo control artroscópico obteniendo una correcta consolidación radiográfica. CONCLUSIONES: El tratamiento artroscópico es una técnica válida, eficaz y segura para el tratamiento de los retardos de consolidación de las fracturas transversales del hueso semilunar, y evita las complicaciones y lesión de las partes blandas de las técnicas por cirugía abierta

BACKGROUND AND AIM: Lunate traumatic fractures represent between 0.5% and 1% of carpal bone fractures. Transverse fracture through the body of the lunate (type V) are the least frequent and need surgical treatment if displaced, because it has a high risk of necrosis or pseudoarthrosis. The objective of this paper is to present our experience with arthroscopic treatment in patients with a delay in consolidation after a transverse fracture through the body of the lunate. METHODS: Two clinical cases of delay in consolidation in transverse fracture through the body of the lunate are presented. Both cases have delay in consolidation. RESULTS: Both fractures were misdiagnosed in initial simple radiographic exploration and were diagnosed with computerised tomography. Both patients were treated by debridement, bone grafting and osteosynthesis under arthroscopic control, obtaining a correct radiographic consolidation. CONCLUSION: Arthroscopic treatment is a valid, effective and safe technique for the treatment of delay in consolidation of transverse fractures through the body of the lunate and avoids complications and soft tissues injury of the open surgery techniques

Biomechanical Factors in Stability of the Forearm.

In the forearm, ligaments and joints act in unison to facilitate placement of the hand in 3-dimensional space and transmit loads across the upper extremity. Intricate, effective forearm stabilizers facilitate physiologic motions and restrict abnormal ones. The proximal radioulnar joint, interosseous ligament complex, and distal radioulnar joint work together to ensure the forearm is stable. Each ligament and joint is designed to leverage its biomechanical advantages. Damage destabilizes the synergy of the forearm and results in debilitating injury patterns. Physicians need to understand how all these structures work together to be able to quickly diagnose and treat these forearm injuries.

The Weekend Warrior: Common Hand and Wrist Injuries in Athletes.

Weekend warriors are individuals who condense their weekly physical activity into extended intervals over one or two days.1 Excessive physical activity can result in a multitude of overuse and traumatic upper extremity injuries. The purpose of this review is to highlight the etiology and management of the more common hand and wrist injuries in athletes.

Growth Disturbance Following Intra-articular Distal Radius Fractures in the Skeletally Immature Patient.

INTRODUCTION: The purpose of this study was to characterize the incidence of growth disturbance following intra-articular distal radius fractures in skeletally immature patients and to assess early radiographic and functional outcomes. METHODS: A retrospective investigation of pediatric patients with intra-articular distal radius fractures between 1997 and 2012 at a single institution was performed. Pathologic fractures and fractures in patients with closed physes were excluded. In total, 28 patients (24 males, 4 females), with a mean age of 13.8 years and mean follow-up of 31.7 months, met inclusion criteria. Fractures were categorized according to the Salter-Harris classification, and all radiographs were assessed for evidence of physeal disturbance. Information regarding treatment and early clinical results were obtained from a medical record review. Functional outcomes using the Disabilities of the Arm, Shoulder, and Hand (DASH) and Modified Mayo Wrist Score (MMWS) were collected. Fisher exact test was used to compare the incidence of physeal arrest in the study population to previously published rates of physeal arrest in extra-articular fractures involving the distal radius. Because the data were not parametrically distributed, the Mann-Whitney-Wilcoxon test was used to compare those who did and did not develop physeal arrest. RESULTS: Of the 28 patients, 9 (32%) sustained Salter-Harris III fractures and 19 (68%) sustained Salter-Harris IV fractures. Growth disturbance occurred in 12 (43%) patients, comprised of 3 Salter-Harris III fractures and 9 Salter-Harris IV fractures; 7 of these patients underwent surgical intervention to address deformity. All 4 children age 10 years or younger had growth arrests that underwent subsequent procedures for a skeletal rebalancing of the wrist. No significant differences in DASH or MMWS were seen in the short term between patients who did or did not have physeal arrest. CONCLUSIONS: Intra-articular distal radius fractures in skeletally immature patients have a considerably higher rate of physeal growth arrest than extra-articular physeal fractures. Following acute management aimed at restoring and preserving anatomic physeal and articular alignment, follow-up radiographs should be obtained to evaluate for physeal arrest in skeletally immature children. Patients and families should be counseled regarding the high rate of growth disturbance and the potential need for deformity correction in the future, particularly in younger children. LEVEL OF EVIDENCE: IV-case series.

Comparison of three different methods to estimate the burden of disease of burn injuries in Western Australia in 2011-2018.

BACKGROUND: Priority setting and resource allocation in health care, surveillance and interventions is based increasingly on burden of disease. Several methods exist to calculate the non-fatal burden of disease of burns expressed in years lived with disability (YLDs). The aim of this study was to assess the burden of disease due to burns in Western Australia 2011-2018 and compare YLD outcomes between three existing methods. METHODS: Data from the Burns Service of Western Australia was used. Three existing methods to assess YLDs were compared: the Global Burden of Disease (GBD) method, a method dedicated to assess injury YLDs (Injury-VIBES), and a method dedicated to assess burns YLDs (INTEGRIS-burns). RESULTS: Incidence data from 2,866 burn patients were used. Non-fatal burden of disease estimates differed substantially between the different methods. Estimates for 2011-2018 ranged between 610 and 1,085 YLDs per 100.000 based on the Injury-VIBES method; between 209 and 324 YLDs based on the INTEGRIS-burns method; and between 89 and 120 YLDs based on the GBD method. YLDs per case were three to nine times higher when the Injury-VIBES method was applied compared to the other methods. Also trends in time differed widely through application of the different methods. There was a strong increase in YLDs over the years when the Injury-VIBES method was applied, a slight increase when the INTEGRIS-burns method was applied and a stable pattern when the GBD method was applied. CONCLUSION: This study showed that the choice for a specific method heavily influences the non-fatal burden of disease expressed in YLDs, both in terms of annual estimates as well as in trends over time. By addressing the methodological limitations evident in previously published calculations of the non-fatal burden of disease, the INTEGRIS-burns seems to present a method to provide the most robust estimates to date, as it is the only method adapted to the nature of burn injuries and their recovery.

Associations between initial injury severity in acute hand, wrist or forearm injuries and disability ratings and time to return to work.

BACKGROUND: This study aimed to examine the relationships between the initial anatomic severity of hand, wrist and forearm injuries, as evaluated by the Modified Hand Injury Severity Score (MHISS), and each of the following parameters: disability rating and time to return to work. METHODS: In this study, 94 patients who underwent operations due to acute hand, wrist and forearm injuries were included. MHISS was used to assess the severity of the injury. Disability rates of the patients were calculated six months after injury in accordance with the 'Regulation on Disability Criteria, Classification and Health Board Reports to be Given to Disabled People'. The time to return to work was defined as the length of time (in days) between the injury and the patient's return to work. Spearman rank correlation analysis was performed to analyse correlations between the MHISS and each of the following: disability rates and time to return to work. RESULTS: The mean overall MHISS was 125.23 (5-880). The mean overall upper extremity disability ratio (UEDR) was 17.64±22.6 (range: 0-94), and the mean overall total body disability ratio (TBDR) was 10.57±13.45 (range: 0-56). Among the study population, 87 (92.6%) patients were able to return to their jobs. The mean overall time to return to work was 138.69 (range: 35-365 days). A statistically significant correlation was found between MHISS and UEDR, TBDR and time to return to work and UEDR, TBDR (p<0.001). CONCLUSION: As a result, as the initial injury severity increased, greater disability remained and the time to return to work increased. Predicting prognosis by determining the injury severity in the initial evaluation of patients may be important in predicting a patient's future permanent disability level, which can contribute to maintaining patient expectations at a reasonable level, thereby aiding in psychosocial support.

The Use of Contact Biomechanics to Study the Intact, Proximal Row Carpectomy and Scaphoid Excision, Four Bone Fusion Wrist.

The study of contact biomechanics of the wrist is a challenge. This is partly due to the relatively small size of the joint as well as the lack of space in the radiocarpal joint which makes the delivery of investigative materials such as pressure sensitive film without causing artifact, difficult. Fortunately, a number of authors have studied the intact wrist, the scapholunate ligament injured wrist, the proximal row carpectomy and the scaphoid excision, four bone fusion. Despite some contrasting findings, there are some general concepts that we understand about wrist mechanics.

Does a Hand Strength-Focused Exercise Program Improve Grip Strength in Older Patients With Wrist Fractures Managed Nonoperatively?: A Randomized Controlled Trial.

OBJECTIVE: Distal radius fractures in the older population significantly impair grip strength. The aim of the study was to investigate whether a hand strength focused exercise program during the period of immobilization for nonoperatively managed distal radius fractures in this population improved grip strength and quality of life. DESIGN: This is a single-center randomized controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. Fifty-two patients older than 60 yrs who experienced distal radius fractures managed nonoperatively with cast immobilization. The intervention group (n = 26) received a home hand strength-focused exercise program from 2 and 6 wks after injury while immobilized in a full short arm cast. The control group (n = 26) performed finger range of motion exercises as per protocol. Primary outcome was grip strength ratio of injured arm compared with uninjured arm. Secondary outcome included functional scores of the 11-item shortened version of the Disabilities of the Arm, Shoulder and Hand. Outcomes were measured at 2, 6, and 12 wks after injury. RESULTS: The intervention group significantly improved grip strength ratio at both 6 and 12 wks (6 wks: 40% vs 25%, P = 0.0044, and 12 wks: 81% vs 51%, P = 0.0035). The intervention group improved the 11-item Disabilities of the Arm, Shoulder and Hand score at 12 wks; however, this was not statistically significant (25 vs 40, P = 0.066). CONCLUSIONS: A hand strength-focused exercise program for elderly patients with distal radius fractures while immobilized significantly improved grip strength.

Wrist deformity, bother and function following wrist fracture in the elderly.

OBJECTIVE: Wrist deformity in older people is common following treatment for a wrist fracture, particularly after non-surgical treatment. A cohort of older wrist fracture patients were surveyed by telephone regarding perceived deformity, bother with deformity and patient-reported wrist function. The objectives were to: (1) determine whether older patients with wrist fractures perceived a deformity of their wrist and if they were bothered by it; (2) test if there were associations between deformity and treatment-type and between deformity and function; (3) test for associations between bother and treatment-type and between bother and function; (4) measure the test-retest reliability of the 'bother' question. RESULTS: Of 98 eligible patients who were invited to participate, 41 responded. Out of 41, 14 (34%) believed they had a deformity and 4 (10%) reported that they were bothered by the appearance of their wrist. Deformity was associated with non-surgical treatment (RR = 3.85, p = 0.006) but was not significantly associated with functional outcomes (p = 0.15). All those who were bothered belonged to the non-surgical treatment group. Bother was significantly associated with poorer functional outcomes (p = 0.006) and this association was clinically significant (MD = 35 points). The deformity and bother questions were found to have excellent test-retest reliability; κ = 1.00 and κ = 0.92, respectively.

Deterioration of initially accepted radiological alignment of conservatively treated AO type-C distal radius fractures: mid-term outcome.

BACKGROUND AND AIMS: It still remains controversial how often the once-accepted radiological alignment of an AO type-C distal radius fracture deteriorates after conservative treatment, and to what extent this deterioration is perhaps associated with patient-rated outcome measures (PROms). Thus, we aimed to evaluate this radiological deterioration and its association with mid-term functional follow-up. PATIENTS AND METHODS: We retrospectively reviewed 66 patients (mean age at fracture 53 years, SD 14.1, range 18-73, female 65%) with 68 C-type distal radius fractures at a mean of 6.7 years (SD 0.5 years, range 5.8-7.7 years) after primary closed reduction and cast immobilization. Radiographs of the wrists were taken and analysed for any radial shortening, dorsal tilt or step-off at the joint surface. Range of motion and grip strength were measured. In addition to the radiological result, primary outcome measures included Quick Disabilities of the Arm, Shoulder and Hand (QDash) and Patient-Rated Wrist Evaluation (PRWE). RESULTS: At mid-term follow-up, an acceptable anatomical radiological result was seen in only 22 wrists (32%). Deterioration of the once-achieved and accepted primary alignment was seen in a majority of cases (68%). Radial shortening of ≥ 2 mm was found in 34 wrists (51%, mean 4 mm, range 2-8 mm), with no association with QDash (12.8 vs. 5.5, p = 0.22) or PRWE (9.1 vs. 5.7, p = 0.40). Only four patients (6%) showed step-off at the joint surface (mean 1.1 mm, range 0.5-2 mm). Twenty-two wrists (32%) showed dorsal tilt of ≥ 10° (five with volar tilt of 15°-25°), with no effect on QDash or PRWE (14.7 vs. 6.5, p = 0.241 and 10.1 vs. 5.8, p = 0.226). Altogether, patients with dorsal tilt, step-off or shortening did not show significantly worse QDash (10.3 vs. 5.7, p = 0.213) or PRWE (8.1 vs. 5.1, p = 0.126) versus those with none. Twenty-nine (43%) of the patients had deficits in range of motion (ROM), either in extension (39%), flexion (43%), supination (16%) or pronation (4%), or combinations of these. Worse extension was associated with worse QDash (15.9 vs. 5.0, p = 0.037), flexion deficit with worse PRWE (11.5 vs. 4.4, p = 0.005) and supination deficit with both QDash (21.7 vs. 6.8, p = 0.025) and PRWE (18.9 vs. 5.2, p = 0.007). CONCLUSIONS: The initially accepted radiological alignment of AO type-C radius fractures deteriorated in a majority of cases during conservative treatment. However, this deterioration was fairly mild and showed no significant association with functional outcome. Restricted ROM showed some association with PROms. LEVEL OF EVIDENCE: IV.

Ulnar-Sided Wrist Pain in the Athlete.

Ulnar-sided wrist pain is a common problem in athletes that can be challenging owing to its frequent combination of overuse in conjunction with acute injury. Repetitive pronosupination, wrist flexion and extension, as well as radial and ulnar deviation can predispose the athlete to injury of ulnar structures. Careful understanding of the sport-specific injuries as well as the underlying biomechanics are key to understanding and treating the athlete. In this article, we discuss the most frequent causes of ulnar-sided wrist pain in the athlete and focus on anatomy and pathophysiology, presentation, and diagnosis, as well as nonoperative and operative treatment options.

VIDEO: Dynamic Ultrasound Evaluation for Soft-Tissue Injuries of the Extremities: Hand, Wrist, and Ankle.

OBJECTIVE. The purpose of this article is to show the sonographic anatomy of the extremities relevant to various ligamentous, tendinous, and articular injuries occurring in the hand, wrist, and ankle. A brief discussion and depiction of the specific elements relevant to the pathophysiologic mechanism of these entities is followed by demonstrations of the dynamic ultrasound techniques that can be used to diagnose these injuries. The schematics and video clips illustrate the normal and pathologic features of these injuries. The first two videos discuss soft-tissue injuries to the hand and wrist, and the third addresses ankle injuries. CONCLUSION. After clinical assessment, dynamic ultrasound examination is a useful tool for diagnosing and assessing the degree of severity of several soft-tissue injuries to the extremities, some of which can be detected only during active movement. Familiarity with these specific dynamic techniques will enhance the value of the ultrasound examination.

Avulsion Injuries of the Hand and Wrist.

Injuries of the hand and wrist are frequently encountered in radiology. Avulsions of the hand and wrist are a heterogeneous group of injuries, but they often have a characteristic imaging appearance that relates to the intricate bone and soft-tissue anatomy and the mechanism of injury. The imaging appearance and this intricate form and function dictate treatment of hand and wrist avulsions. This article reviews frequently and infrequently encountered avulsion injuries and describes abnormalities that may mimic the imaging appearance of avulsions. Specifically discussed entities include the Bennett and reverse Bennett fracture, ulnar collateral ligament avulsion, radial and ulnar styloid process avulsion, triquetral avulsion, mallet and jersey finger, central slip avulsion, and acute and chronic volar plate avulsion injuries. Uncommon avulsion injuries are also described and include avulsions of the scapholunate ligament, extensor carpi radialis longus and brevis tendons, trapeziometacarpal ligament, radial collateral ligament, and flexor digitorum profundus tendon. Emphasis is placed on the relevant anatomy and typical imaging findings for each diagnosis, with pertinent clinical history, pathophysiologic evaluation, and treatment discussed briefly. Understanding the anatomy and expected imaging findings can aid the radiologist in recognizing and characterizing these injuries.©RSNA, 2020.
