Ulnar carpal translation following palmar locking plate fixation for distal radius fractures: a retrospective analysis.

BACKGROUND: Concomitant injuries to the radiocarpal ligaments may occur during episodes of distal radius fractures, which may not cause acute subluxation or dislocation but can lead to radiocarpal instability and progress over time. This study aimed to analyze the occurrence of ulnar carpal translation (UCT) after open reduction and internal fixation of distal radius fractures and evaluate the associated factors of UCT. METHODS: The retrospective study has been done now and includes patients treated between 2010 and 2020 who had undergone reduction and locking plate fixation of distal radius fractures. We assessed radiographs taken immediately after the operation and at 3 months post-operation, enrolling patients with UCT for evaluation. In addition to demographic data, we evaluated radiographic parameters, including fracture pattern, fragment involvement, and ulnar variance. We also assessed the palmar tilt-lunate (PTL) angle to determine associated rotatory palmar subluxation of the lunate (RPSL). RESULTS: Among the 1,086 wrists, 53 (4.9%) had UCT within 3 months post-operation. The majority of wrists with UCT exhibited normal to minus ulnar variance (49 wrists; mean: -1.1 mm), and 24 patients (45.3%) had concomitant RPSL. Fracture classification was as follows: 19 type A3 (35.8%), 5 type C1 (9.4%), 11 type C2 (20.8%), and 18 type C3 (34.0%). Radial styloid was involved in 20 wrists (37.7%), palmar rim in 18 wrists (34.0%), dorsal rim in 25 wrists (47.2%), and die-punch fractures in 3 wrists (5.7%). Concomitant ulnar styloid fractures were present in 29 wrists (54.7%). CONCLUSION: This study highlights the potential for UCT to occur following reduction and fixation of distal radius fractures, particularly in cases with a more severe fracture pattern and combined with ulnar minus variance. The high incidence of concomitant RPSL provides further evidence for the possibility of associated radiocarpal ligament insufficiency after distal radius fracture.

Pre-existing osteoporosis and serum vitamin D levels in patients with distal radius fractures: are we missing something?

INTRODUCTION: Given the significant therapeutic gap for osteoporosis, this study aims to investigate the most common osteoporosis-related fracture. The analysis will also consider patients' serum vitamin D levels and the indications for basic osteoporosis diagnostic tests and osteoporosis therapy prior to fracture. MATERIALS AND METHODS: This prospective clinical trial included patients with distal radius fractures who underwent surgery at our hospital between 1 April 2021 and 7 April 2022. Blood samples were taken from all participants and existing risk factors for osteoporosis were recorded. In addition, the indication for a guideline-based osteoporosis diagnosis was assessed and the risk of another future fracture with FRAX® was calculated. This information was used to decide whether there was an indication for specific osteoporosis therapy. RESULTS: A diagnosis gap of 53% and a treatment gap of 84% were identified among the 102 patients investigated. The patients' ages ranged from 46 to 91 years, with an average vitamin D level of 57 nmol/l, which was below the recommended level of 75 nmol/l. It was noted on a monthly basis that the vitamin D level (without substitution) never exceeded the recommended value of 75 nmol/l in any month. Three-quarters of patients had indications for a baseline osteoporosis diagnosis, yet less than 50% received one. According to FRAX® data, 57% of patients had indications for specific osteoporosis treatment before experiencing the fracture. CONCLUSION: Even without a previous distal radius fracture, many patients are in need of osteoporosis diagnosis or treatment. Our research suggests that patients with distal radius fractures should have their vitamin D levels checked via a blood test and be evaluated for osteoporosis. As endogenous vitamin D levels are often inadequate, year-round vitamin D supplementation should be considered for the prevention of osteomalacia and as a basis for the treatment of osteoporosis.

Editorial Commentary: Supplemental Wrist Arthroscopy May Not Be the Key to Improving Outcomes in Surgical Treatment of Distal Radius Fractures.

For decades, the surgical treatment of intra-articular distal radius fractures has relied on indirect reduction. The goal is to mitigate the articular stepoff that has been associated with radiographic progression of arthritic changes. Continued advances in wrist arthroscopy give us the opportunity for direct visualization of these reductions, direct assessment of intra-articular screws, and diagnosis and treatment of concomitant soft tissue pathology, including those to the scapholunate interosseous ligament, lunotriquetral interosseous ligament, and the triangular fibrocartilage complex. Despite this, however, supplemental wrist arthroscopy does not appear to improve outcomes at 1 year in patients with distal radius fractures treated with volar locking plates.

Paediatric bilateral 'floating elbow'.

A child sustained an ipsilateral supracondylar humerus (SCH) and distal both-bone forearm fractures bilaterally, in addition to facial injuries, following a fall from height. He was managed surgically by closed reduction and pinning for both SCH and distal end radius fractures bilaterally. At the final follow-up, all the fractures had united uneventfully, and he had no functional limitations or cosmetic concerns. We conclude that a floating elbow in the paediatric population is an uncommon injury, and the bilateral scenario is even rarer. One should be vigilant for compartment syndrome; early surgical fixation may give better results.

Virtual Coaching and the Reduction of Radial Head Subluxation: A Case Series.

OBJECTIVES: After the establishment of the virtual pediatric emergency medicine clinic at our institution, we noted that several physicians independently began to instruct caregivers virtually on reducing a radial head subluxation. We thus conducted a case series to investigate the number, success, and follow-ups for the virtual reduction of radial head subluxation. METHODS: The electronic medical records at our institution were searched from the inception of the virtual clinic in May 2020 until August 2022 (inclusive), for visits and discharge diagnosis containing the word "elbow" or "arm." RESULTS: Fourteen charts were retrieved; however, 2 were excluded because they were not a suspected radial head subluxation. A virtual reduction was attempted for eight (66.7%) of the 12 patients. In 6 of 8 patients (75.0%), the reduction was deemed successful, and for 2 patients (25.0%), it was deemed unsuccessful. Of the latter, one was found to have a nondisplaced radial neck fracture. All 4 patients (33.3%) for whom a virtual reduction was not attempted were referred to the emergency department. CONCLUSIONS: Virtual video coaching of pulled elbow reduction was completed at our institution with overall good success rate. All the physicians involved noted the essential need and benefits of video conferencing for successfully reducing radial head subluxation. We note that a pediatric population may be more amenable to video-based appointments than other populations due to their caregivers' familiarity with digital technology. Finally, as nonphysician models of healthcare delivery for virtual urgent care visits expand, we propose a checklist based on our experience to ensure patient safety.

Evaluating Male Patients' Understanding of Osteoporosis Evaluation and Treatment Following a Distal Radius Fracture.

PURPOSE: Current estimates suggest that 1-2 million men in the United States have osteoporosis, yet the majority of osteoporosis literature focuses on postmenopausal women. Our aim was to understand men's awareness and knowledge of osteoporosis and its treatment. METHODS: Semistructured interviews were conducted with 20 male patients >50 years old who sustained a low-energy distal radius fracture. The goal was to ascertain patients' knowledge of osteoporosis, its management, and experience discussing osteoporosis with their primary care physicians (PCP). RESULTS: Participants had little knowledge of osteoporosis or its treatment. Many participants regarded osteoporosis as a women's disease. Most participants expressed concern regarding receiving a diagnosis of osteoporosis. Several patients stated that they believe osteoporosis may have contributed to their fracture. Families, friends, or mass media served as the primary information source for participants, but few had good self-reported understanding of the disease itself. The majority of participants reported never having discussed osteoporosis with their PCPs although almost half had received a dual x-ray absorptiometry scan. Participants expressed general interest in being tested/screened and generally were willing to undergo treatment despite the perception that medication has serious side effects. One patient expressed concern that treatment side effects could be worse than having osteoporosis. CONCLUSION: Critical knowledge gaps exist regarding osteoporosis diagnosis and treatment in at-risk male patients. Specifically, most patients were unaware they could be osteoporotic because of the perception of osteoporosis as a women's disease. Most patients had never discussed osteoporosis with their PCP. CLINICAL RELEVANCE: Male patients remain relatively unaware of osteoporosis as a disease entity. Opportunity exists for prevention of future fragility fractures by improving communication between patients and physicians regarding osteoporosis screening in men following low-energy distal radius fractures.

Gait characteristics in patients with distal radius fracture using an in-shoe inertial measurement system at various gait speeds.

BACKGROUND: Distal radius fractures (DRF) commonly occur in early postmenopausal females as the first fragility fracture. Although the incidence of DRF in this set of patients may be related to a lower ability to control their balance and gait, the detailed gait characteristics of DRF patients have not been examined. RESEARCH QUESTION: Is it possible to identify the physical and gait features of DRF patients using in-shoe inertial measurement unit (IMU) sensors at various gait speeds and to develop a machine learning (ML) algorithm to estimate patients with DRF using gait? METHODS: In this cross-sectional case control study, we recruited 28 postmenopausal females with DRF as their first fragility fracture and 32 age-matched females without a history of fragility fractures. The participants underwent several physical and gait tests. In the gait performance test, the participants walked 16 m with the in-shoe IMU sensor at slower, preferred, and faster speeds. The gait parameters were calculated by the IMU, and we applied the ML technique using the extreme gradient boosting (XGBoost) algorithm to predict the presence of DRF. RESULTS: The fracture group showed lower hand grip strength and lower ability to change gait speed. The difference in gait parameters was mainly observed at faster speeds. The amplitude of the change in the parameters was small in the fracture group. The XGBoost model demonstrated reasonable accuracy in predicting DRFs (area under the curve: 0.740), and the most relevant variable was the stance time at a faster speed. SIGNIFICANCE: Gait analysis using in-shoe IMU sensors at different speeds is useful for evaluating the characteristics of DRFs. The obtained gait parameters allow the prediction of fractures using the XGBoost algorithm.

Antibiotic-loaded spacer arthroplasty in a terrible triad injury with unreconstructable radial head fracture: a case report.

BACKGROUND: Radial head arthroplasty is a viable option in cases with terrible triad injuries of elbow, wherein the radial head sustains significant comminution that precludes reconstruction. Nevertheless, this alternative is not recommended for individuals with poor elbow skin conditions, accompanied neuropsychiatric disorders, or low patient compliance. This case report presents a patient with bilateral terrible triad injury, along with the aforementioned conditions. The report outlines the treatment challenges of such a case and proposes potential solutions. CASE PRESENTATION: A 37-year-old Persian male patient presenting with a bilateral terrible triad fracture-dislocation and a history of psychoactive substance abuse, was admitted to our emergency department. The patient underwent radial head replacement using a cement spacer containing antibiotics, due to the comminuted radial head in the presence of a contaminated wound on the left elbow. The fracture of the right side was successfully fixed. Subsequent to discharge, the patient did not attend any follow-up appointments. After a period of 6 months, he was admitted to the psychiatric ward and orthopedic consultation was requested to evaluate the patient. CONCLUSION: In acute terrible triad injuries with unreconstructable radial head fractures where arthroplasty with metallic prostheses may not be suitable due to contaminated wounds, unstable psychiatric condition, and low patient cooperation, temporary orthopedic cement spacers can maintain elbow biomechanics, stability, and sterility.

Predictive factors of distal radioulnar joint instability after surgical treatment of distal radius fractures.

Distal radioulnar joint (DRUJ) instability is a common postoperative complication of distal radius fractures, seriously impacting patients' quality of life. This study investigated its possible influencing factors to determine prognosis and to guide treatment better. We retrospectively included a series of patients with distal radius fractures that underwent volar locking plate fixation. Basic patient information and imaging parameters were collected. The incidence of DRUJ instability during follow-up was recorded, and factors associated with DRUJ instability were determined using univariate analysis and multifactorial logistic regression analysis. A total of 159 patients were enrolled in this study. At 6 months of follow-up, 54 patients (34.0%) had DRUJ instability, and multivariate analysis showed coronal plane displacement (OR, 1.665; 95% CI, 1.091-2.541), fracture classification (OR, 0.679; 95% CI, 0.468-0.984) and DRUJ interval (OR, 1.960; 95% CI, 1.276-3.010) were associated with DRUJ instability after volar locking plate. DRUJ interval, coronal plane displacement, and fracture classification are associated with DRUJ instability during follow-up. Therefore, preoperative risk communication and intraoperative attention to recovering relevant imaging parameters are necessary for these patients.

Median nerve entrapment during closed reduction of antebrachium fracture in a child.

This is a case report of a four-year-old boy who suffered a forearm fracture managed with closed reduction and casting for six weeks. Postoperatively, the patient showed symptoms of median nerve affection which was misinterpreted as neuropraxia. Ultrasonography of the forearm revealed that the median nerve was trapped in the radius fracture site. The patient underwent a second operation with neurolysis and nerve grafting. This case report highlights the use of ultrasonography in the diagnostics of nerve entrapment neuropathy.

Posttraumatic arthritis and functional outcomes of nonoperatively treated distal radius fractures after 3 years.

Recent studies have shown that distal radius fractures (DRFs) in elderly patients can be treated nonoperatively with good functional results after 1 year. However, scientific evidence regarding longer follow-up to assess posttraumatic arthritis (PA), complications, and functional outcomes is scarce. This prospective case series aimed to evaluate these outcomes in a cohort of patients ≥ 65-year-old with nonoperatively treated DRFs after a minimum of 3 years. The primary outcome was PA. Secondary outcomes were complications, Quick Disabilities of the Arm, Shoulder and Hand Outcome Measure (QuickDASH), Patient-Rated Wrist/Hand Evaluation (PRWHE), pain, range of motion and grip strength. The full data of 32 patients with a mean follow-up of 3.3 years were available: 10/32 patients had radiological signs of PA, but only 2 of these patients reported pain. A total of 11/32 fractures healed in malunion (> 10° dorsal angulation). There was no significant difference in QuickDASH or PRWHE from 1 year to the latest follow-up after more than 3 years. This study thus adds to the literature stating that radiological signs, including PA and malunion, do not necessarily result in symptoms. Moreover, it underpins that nonoperative treatment of these patients results in good functional outcomes after 1 and 3 years.

Improved forearm rotation even after early conversion to below-elbow cast for non-reduced diaphyseal both-bones forearm fractures in children: a secondary 7.5-year follow up of a randomized trial.

BACKGROUND AND PURPOSE: previous RCT compared short-term results of above-elbow cast (AEC) with early conversion to below-elbow cast (BEC) in children with non-reduced diaphyseal both-bone forearm fractures. After 7 months both groups had comparable function. Our primary aim was to investigate whether forearm rotation improves or worsens over time. Secondary aims were loss of flexion and extension of the elbow and wrist, patient-reported outcomes measures, grip strength ratio, and radiographic assessment. PATIENTS AND METHODS: We performed long-term follow-up (FU) of a previous RCT. All patients were invited again for the long-term FU measurements. Primary outcome was limitation of forearm rotation. Secondary outcomes were loss of flexion and extension of the elbow and wrist compared with the contralateral forearm, the ABILHAND-Kids questionnaire and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, grip strength ratio, and radiographic assessment. RESULTS: The mean FU was 7.5 (4.4-9.6) years. Of the initial 47 children, 38 (81%) participated. Rotation improved in both groups over time, with no significant difference in the final forearm rotation: 8° (SD 22) for the AEC group and 8° (SD 15) for the BEC group with a mean difference of 0° (95% confidence interval -13 to 12). Secondary outcomes showed no statistically significant differences. Finally, children < 9 years almost all have full recovery of function. CONCLUSION: Long-term follow-up showed that loss of forearm rotation after a non-reduced diaphyseal both-bone forearm fracture improved significantly compared with that at 7 months, independent of the initial treatment and children aged < 9 will have almost full recovery of function. This substantiates that the remaining growth behaves like a "friend" at long-term follow-up.

Recurrent Infections After Percutaneous Pinning of a Proximal Radius and Ulna Fracture.

Elbow fractures in the pediatric population are an exceedingly common injury, comprising 5% to 10% of all pediatric fractures, with supracondylar fractures being the most common of the subset. Radial neck fractures are less frequent, comprising only 1% of all pediatric fractures. We provide a case report of a 7-year-old girl with a left radial neck and proximal ulna fracture. A 7-year-old girl presented to the emergency department after falling off a rock wall the day before. Imaging showed a left proximal ulna and proximal radial neck fracture. The patient underwent percutaneous reduction and fixation, complicated by subsequent infection requiring surgical débridement. The patient then developed a recurrent infection 1 year later, requiring repeat irrigation and débridement. The patient has since made a full recovery, returned to activities of daily living, and regained a full range of motion. Radial neck fractures have a low incidence and have been frequently associated with poor outcomes. The main mechanism by which these fractures occur is due to falling on an outstretched arm. Percutaneous pinning is often recommended after unsuccessful attempts at closed reduction because open reduction is often complicated by postoperative stiffness. As with any procedure that involves breaking the skin, there is a risk of infection. However, there is unclear evidence regarding ideal perioperative management to prevent postoperative infection.

The Effect of an Intraoperative Real-Time Counter on Radiation Exposure Events During Operative Treatment of Distal Radius Fractures.

PURPOSE: Occupational radiation exposure can have adverse health consequences for surgeons. The purpose of this study was to determine if utilization of an intraoperative, real-time radiograph counter results in decreased radiation exposure events (REEs) during open reduction and internal fixation (ORIF) of distal radius fractures (DRFs). METHODS: We reviewed all cases of isolated ORIF DRFs performed at a single center from January 2021 to February 2023. All cases performed on or after January 1, 2022 used an intraoperative radiograph counter, referred to as a "shot-clock" (SC) group. Cases prior to this date were performed without a SC and served as a control group (NoSC group). Baseline demographics, fracture, and surgical characteristics were recorded. Final intraoperative radiographs were reviewed to record reduction parameters (radial inclination, volar tilt, and ulnar variance). REEs, fluoroscopy exposure times, and total radiation doses milligray (mGy) were compared between groups. RESULTS: A total of 160 ORIF DRF cases were included in the NoSC group, and 135 were included in the SC group. The NoSC group had significantly more extra-articular fractures compared with the SC group. Reduction parameters after ORIF were similar between groups. The mean number of REEs decreased by 48% in the SC group. Cases performed with the SC group had significantly lower total radiation doses (0.8 vs 0.5 mGy) and radiation exposure times (41.9 vs 24.2 seconds). Mean operative times also decreased for the SC group (70 minutes) compared with that for the NoSC group (81 minutes). CONCLUSIONS: A real-time intraoperative radiograph counter was associated with decreased REEs, exposure times, and total radiation doses during ORIF DRFs. Cases performed with a SC had significantly shorter operative times without compromising reduction quality. Using an intraoperative SC counter during cases requiring fluoroscopy may aid in decreasing radiation exposure, which serves as an occupational hazard for hand and upper-extremity surgeons. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Complications Following Volar Locking Plate Fixation of Distal Radius Fractures in Adults: A Systematic Review of Randomized Control Trials.

PURPOSE: The purpose of this study was to assess the incidence of postoperative complications following volar locking plate (VLP) fixation of distal radius fractures (DRFs). METHODS: A search using keywords and subject headings to represent the concepts of volar plating and radius fractures was generated. Databases such as MEDLINE (Ovid), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCO) were searched from inception to November 24, 2021, for randomized controlled trials that reported complications following DRF treated with VLP. Inclusion criteria were studies with adult patients (aged ≥18 years) randomized to VLP fixation without other concomitant surgical interventions, with a minimum follow-up of 3 months. Study sample characteristics and post-surgical complications were extracted. The Cochrane Risk of Bias tool was used to evaluate quality of evidence. RESULTS: Of the 4,059 articles identified using the search strategy, 1,778 titles/abstracts and 856 full-text articles were screened for inclusion, of which 35 articles were included for data extraction. Overall, 1,419 patients with a DRF were randomized to VLP fixation. The mean age was 60.3 years. The overall complication rate was 30.8% following VLP fixation, with 12.4% being major complications. The most common complications were median nerve-related (7.1%) and hardware removal (6.8%), secondary to other complications. Tenosynovitis was the most common tendon-related complication (3.4%). Other complications included complex regional pain syndrome (2.4%), malunion (1.3%), superficial wound infections (1.9%), and tendon rupture (1.3%). CONCLUSIONS: A meta-analysis of high-quality studies that discuss the complications after VLP fixation for DRF showed an overall complication rate of 30.8%. VLP may be related to more hardware-related complications than those previously reported. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Early complications of percutaneous K-wire fixation in pediatric distal radius fractures-a prospective cohort study.

INTRODUCTION: Distal radius fractures (DRF) are the most common pediatric fractures, but the current evidence for management remains inconclusive. Closed reduction and percutaneous pinning (CRPP) provide excellent stability but are not complications-free. Therefore, a thorough evaluation of their adverse events is necessary to provide reliable information on risks and benefits in different clinical scenarios. The current literature lacks studies conducted with rigorous grading systems and uniform follow-up protocols on this topic. This prospective cohort study used a validated grading scheme to analyze complications associated with CRPP in an unselected pediatric population with displaced, unstable distal third radius fractures. MATERIALS AND METHODS: One hundred and nineteen DRFs (one hundred and sixteen patients) treated with CRPP were enrolled in the study. All patients were followed 4 weeks, 5 weeks, 3 months, and 6 months after the surgery. The same protocol, comprising structured history, physical and radiological assessment, was used throughout the study. All data were prospectively abstracted. The Clavien-Dindo-Sink grading system was used to assess the complications and the Dahl score to evaluate the pin sites. RESULTS: Forty-two wrists (35,3%) had CDS grade I or II complications, and two (1,7%) had a grade III complication. The general complication rate for the study group was 37% (44 complications). Two patients required repeated surgery-deep bone pin-track infection treated with the Masquelet technique and surgical removal of a migrated pin. Among minor complications, pin-site inflammations were the most common-40 wrists (33,6%). CONCLUSIONS: The CRPP is a safe treatment method for DRF in pediatric patients, with a low major complication rate. However, minor adverse events are frequent and can significantly burden the patient's postoperative well-being. The application of rigorous definitions and grading systems should not only lead to the obtainment of high-quality data but also to higher awareness of possible pin tract infections and therefore allow for better therapeutic decisions.

How common are refractures in childhood?

Aims: The aim of this study was to describe the incidence of refractures among children, following fractures of all long bones, and to identify when the risk of refracture decreases. Methods: All patients aged under 16 years with a fracture that had occurred in a bone with ongoing growth (open physis) from 1 May 2015 to 31 December 2020 were retrieved from the Swedish Fracture Register. A new fracture in the same segment within one year of the primary fracture was regarded as a refracture. Fracture localization, sex, lateral distribution, and time from primary fracture to refracture were analyzed for all long bones. Results: Of 40,090 primary fractures, 348 children (0.88%) sustained a refracture in the same long bone segment. The diaphyseal forearm was the long bone segment most commonly affected by refractures (n = 140; 3.4%). The median time to refracture was 147 days (interquartile range 82 to 253) in all segments of the long bones combined. The majority of the refractures occurred in boys (n = 236; 67%), and the left side was the most common side to refracture (n = 220; 62%). The data in this study suggest that the risk of refracture decreases after 180 days in the diaphyseal forearm, after 90 days in the distal forearm, and after 135 days in the diaphyseal tibia. Conclusion: Refractures in children are rare. However, different fractured segments run a different threat of refracture, with the highest risk associated with diaphyseal forearm fractures. The data in this study imply that children who have sustained a distal forearm fracture should avoid hazardous activities for three months, while children with a diaphyseal forearm fracture should avoid these activities for six months, and for four and a half months if they have sustained a diaphyseal tibia fracture.

Baseline predictors related to functional outcomes in patients older than sixty years with complex regional pain syndrome type 1 after distal radius fracture treated conservatively: a prospective observational study.

PURPOSE: This study aimed to analyze baseline predictors of functional outcomes six weeks and at one year follow-up in patients older than 60 years with complex regional pain syndrome type 1 (CRPS I) after distal radius fracture (DRF). METHODS: A total of 120 patients with CRPS I after DRF were prospectively recruited. Presumptive relevant factors were collected and analyzed as potential baseline predictors. Additionally, functional outcomes were assessed at the beginning of physiotherapy treatment, at six weeks after finishing physiotherapy treatment, and at one year follow-up. Patient-Rated Wrist Evaluation; Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire; Jamar dynamometer; and visual analog scale (VAS) were assessed. RESULTS: All participants completed the study. At 6 weeks, the main results showed an association of lower values of grip strength with female sex (p = 0.010), intra-articular DRFs (p = 0.030), longer immobilization time (p = 0.040), lower levels of physical activity (p < 0.001), higher levels of kinesiophobia (p = 0.010), and anxiety (p = 0.020). At 1-year follow-up, the results showed an association of lower values of DASH with higher BMI (p < 0.001) and longer immobilization time (p < 0.001); and higher values of VAS showed an association with older age (p = 0.010), higher BMI (p = 0.010), and lower levels of physical activity (p = 0.040). CONCLUSION: At six weeks, factors such as BMI, immobilization time, physical activity, and kinesiophobia are associated with lower functional outcomes. Additionally, at one year follow-up, BMI, immobilization time, and physical activity continue to be associated with lower functional outcomes in patients with CRPS I after DRF treated conservatively.

[Radiocarpal dislocations and fracture dislocations]. / Radiokarpale Luxationen und Luxationsfrakturen.

Radiocarpal dislocations and fracture dislocations are rare but always severe and complex injuries. They occur frequently in young and active patients as a result of high energy accidents. A detailed clinical and imaging examination and an accurate classification leads to a suitable and mostly surgical treatment strategy. The strategy should consider the most important components of the injury, the bony, the ligamentous and the intracarpal lesions. Delayed sequelae, residual pain and functional impairment are frequent after these severe injuries, but with adequate treatment, good, even long-term functional results are possible.

Comminuted lunate fracture combined with distal radius fracture and scaphoid fracture: A case report.

RATIONALE: Incidence of lunate fractures is very low, less than 1% of all fractures. Lunate fractures generally come from high-energy injuries, often combined with other wrist fractures. Simple lunate fractures can be fixed with screws or Kirschner wires. However, Comminuted lunate fractures are difficult to reduce and fixe by conventional methods. PATIENT CONCERNS: Here we report a 42-year-old male construction worker who was crushed by an excavator bucket and presented with comminuted lunate fracture combined with distal radius fracture and scaphoid fracture. DIAGNOSES: Comminuted lunate fracture, distal radius fracture, and scaphoid fracture. INTERVENTIONS: The posterior approach was used to reconstruct the radial lunate bone with polymethylmethacrylate cement, and cannulated screws were used to fix the scaphoid and distal radius fractures. OUTCOMES: At the 3rd month after surgery, the movement of the right wrist joint improved. At the sixth month after surgery, the patient returned to the building site and began working at the same intensity as before the injury. LESSONS: Although the incidence of comminuted lunate fractures is very low, they occur sometimes. For comminuted lunate fractures, early identification and intervention can preserve most of the function of the wrist joint.
