Non-osteoporotic fractures are associated with increased risk of subsequent major osteoporotic fractures.

We studied the association between non-osteoporotic fractures and future major osteoporotic fractures, using UK health records. Non-osteoporotic fractures were found to increase the risk of major osteoporotic fractures, although to a lesser extent than osteoporotic fractures. This highlights the importance of considering all previous fractures in assessing future fracture risk. PURPOSE: Previous studies demonstrated that osteoporotic fractures-minor and major-increase the risk for future major osteoporotic fractures; we test whether non-osteoporotic fractures are also associated with such increased risk. METHODS: The study is a retrospective cohort study using UK primary care electronic health records. Exposure groups were defined according to fracture location prior to the year 2011 (index date): major, minor, and non-osteoporotic. The outcome of incident major osteoporotic fractures following the index date was compared between the exposure groups and the general population. RESULTS: The general study population included 1,951,388 patients. The exposure groups included 39,931 patients with a prior major osteoporotic fracture, 19,397 with a prior minor osteoporotic fracture, and 50,115 patients with a prior non-osteoporotic fracture. The standardized Incidence Rate Ratio for future major osteoporotic fractures was 2.73 (95% confidence interval: 2.64-2.82), 2.43 (2.32-2.54), and 1.83 (1.74-1.92), respectively. CONCLUSION: Non-osteoporotic fractures are significantly associated with increased risk for future major osteoporotic fractures relative to the general population, yet to a lesser extent compared to major and minor osteoporotic fractures.

[ISOLATED FOURTH EXTENSOR COMPARTMENT TENOSYNOVITIS DUE TO EPIDEMIC RELATED CHANGES IN THE WORKPLACE].

INTRODUCTION: We report on cases of isolated fourth extensor compartment tenosynovitis without evidence of systemic inflammation that occurred in the context of alteration in the work environment due to the COVID-19 epidemic. Early identification of the deleterious effects of virtual/technologically-dependent work from home can aid in treatment and prevention of these conditions. We describe the phenomenon and suggest a treatment approach.

Wrist angle measurements in predicting the presence of a displaced scaphoid fracture.

PURPOSE: Early diagnosis and treatment of scaphoid fractures is critical to achieve union and prevent wrist degenerative arthritis. Plain radiographic measurements can guide the early approach to suspected fractures. Specifically, the ability to predict fracture or fracture stability from plain radiographs may allow the traumatologist to expand initial referral to three-dimensional imaging. We evaluated the ability of four measured angles to predict presence of a scaphoid fracture and stability. METHODS: Fifty patients with a scaphoid fracture and 50 patients without fracture were evaluated for the cortical ring sign, scapho-lunate gapping, lateral scapholunate (SL), radio-scaphoid (RS), radio-lunate (RL), and radio-capitate (RC) angles by two-blinded observers. RESULTS: Measurement of an increased SL interval was associated with the presence of a scaphoid fracture as diagnosed on three-dimensional imaging [odds ratio (OR) 3.0, confidence interval (CI) 1.53-5.87, p = < 0.01]. The measured RL angle was associated with fracture displacement (OR 1.13, 95% CI 1.02-1.25, p = 0.02). CONCLUSIONS: Scapholunate gapping on plain radiographs in the context of a clinically suspected scaphoid fracture should increase suspicion for a fracture and may prompt earlier 3-dimensional imaging, while the presence of an abnormal radiolunate angle should increase wariness for instability and can be used in preoperative planning.

Approach to the Perpendicular Fixation of a Scaphoid Waist Fracture-A Computer Analyzed Cadaver Model.

PURPOSE: In scaphoid fracture screw fixation, the screw is commonly placed along the long axis of the bone, without consideration of the fracture plane. This position is not perpendicular to transverse waist fractures or to the more common horizontal oblique fractures. Our aim was to examine the feasibility and describe possible approaches to, placing a screw perpendicular and in the center of the scaphoid waist fracture. METHODS: Computed tomography of 12 cadaver wrists was performed in 3 positions to examine possible approaches in flexion, neutral, and extension of the wrist. The scans were evaluated using a 3-dimensional model that simulated horizontal oblique (60°) and transverse (90°) fractures. We examined all possible approaches for screw positioning and their deviation from the axis perpendicular to the fracture and in the center of its plane. RESULTS: The preferred approaches for a perpendicular screw in a horizontal oblique fracture were found to be proximal-dorsal in flexion or transtrapezial in the extended or neutral positions (through the volar-radial trapezium). In transverse fractures, the possible approaches were proximal-dorsal or transtrapezial in the flexed or neutral positions and distal in the extended position (volar to volar-radial trapezium). In these approaches, the screw could be placed perpendicularly (deviating by < 10°) and in the center of the fracture in all specimens. CONCLUSIONS: According to this model, it appears feasible to place a perpendicular screw in the center of a horizontal oblique waist fracture using a proximal-dorsal approach in flexion or a transtrapezial approach in neutral or extension positions of the wrist. Palpable landmarks may be used as additional guides to direct these approaches according to the clinical setting. CLINICAL RELEVANCE: Perpendicular screw fixation of horizontal oblique or transverse scaphoid waist fractures is a possible option, if chosen for its biomechanical advantages.

Musculoskeletal disorders among dental hygienist and students of dental hygiene.

OBJECTIVES: The purpose of the present study was to present an up-to-date report on the prevalence of musculoskeletal complaints in dental hygienists and dental hygiene students in Israel. It examined the areas of the body that were most frequently affected and the intensity of pain in both groups. The possible differences between groups and the likelihood that musculoskeletal symptoms in students can be attributed to their workload. METHOD: A modified version of The Nordic Musculoskeletal Questionnaire (NMQ) was used to assess reports of Musculoskeletal disorders (MSD) in general and in different body areas. A numerical pain scale was administered to evaluate pain intensity. RESULTS: Two hundred and five women participated in the study: 85 experienced dental hygienists, 17 dental hygiene students and 103 students in a non-clinical track (control group). MSD reports were the most common in the neck (60%), upper back (52%) and lower back (61%). This tendency was seen across all three groups. Hygiene students differed significantly from the control group in terms of number of body areas with MSD and for pain intensity. By contrast, no significant differences were found between dental hygienists and hygiene students, CONCLUSIONS: The findings suggest that dental hygienists and students are at high risk of developing MSD. The high prevalence of MSD among hygiene students underscores the need to commence intervention prior to the initiation of fieldwork.

First clinical experience with a new injectable recombinant human collagen scaffold combined with autologous platelet-rich plasma for the treatment of lateral epicondylar tendinopathy (tennis elbow).

BACKGROUND: Lateral epicondylitis is a tendinopathy of the common extensor origin at the elbow. When traditional conservative treatment fails, more effective therapies are needed. Vergenix Soft Tissue Repair (STR) Matrix (CollPlant Ltd., Ness-Ziona, Israel) is an injectable gel composed of cross-linked bioengineered recombinant human type I collagen combined with autologous platelet-rich plasma (STR/PRP). The complex forms a collagen-fibrin matrix that promotes cell migration and tissue repair. Based on positive outcomes from preclinical trials, this study is the first clinical trial of STR/PRP on tendinopathy. We hypothesized that STR/PRP would be a safe and effective treatment for lateral epicondylar tendinopathy. METHODS: Patients with chronic lateral epicondylitis underwent treatment with STR/PRP. Outcome assessment included grip strength, functional disability, and changes in sonographic tendon appearance for up to 6 months after treatment. RESULTS: The study enrolled 40 patients. No systemic or local severe adverse events were reported. Clinical evaluation revealed an improvement in the mean Patient-Rated Tennis Elbow Evaluation score from 64.8 before treatment and showed a 59% reduction at 6 months. The 12-Item Short-Form Health Survey questionnaire showed improvement from a mean score of 30.7 to 37.7 at the final follow-up. Grip strength increased from 28.8 kg at baseline to 36.8 kg at 6 months. Improvements in sonographic tendon appearance were evident among 68% of patients. CONCLUSION: STR/PRP is a safe treatment that effectively induces clinically significant improvements in elbow symptoms and general well-being as well as objective measures of strength and imaging of the common extensor tendon within 6 months of treatment of elbow tendinopathy recalcitrant to standard treatments.

[STENOSING FLEXOR TENOSYNOVITIS - COMMON PRACTICE OF FAMILY PHYSICIANS, ORTHOPEDIC AND HAND SURGEONS].

BACKGROUND: The trigger finger is a common condition of the hand that is treated by family physicians, orthopedic and hand surgeons. The patients suffer from pain, triggering of the finger and may develop a flexion contracture of the finger, causing significant functional limitations. AIM: The objectives of this study were to evaluate factors involved in the diagnosis and treatment of this condition, as well as the differences in treatment between specialists. METHODS: The different specialists were asked to rate the importance of symptoms, examination and imaging studies regarding the decision to refer a patient for surgery as well as suggest the treatment of a hypothetical patient complaining of typical symptoms. RESULTS: In the 158 questionnaires collected, the complaint of limited finger range of motion and previous treatment were rated most important. Family physicians stated that age, occupation and rate of recent triggering were considered to be additional important factors (p=.0003). In comparison with hand surgeons, family physicians reported localized tenderness as important, and the need for passive release of the finger locked in flexion as less important (p=.0003). Family physicians were more likely to treat with NSAID [p= 0.0002), orthopedic surgeons with steroid injections (p=0.0004 and hand surgeons with surgery (p=0.0001). CONCLUSIONS: According to this survey, we found differences in the acquaintance of physicians of different backgrounds with the clinical staging of trigger finger, specifically, the significance of finger contracture and indications for surgery. This information may guide training of physicians in all fields.

3-dimensional analysis of scaphoid fracture angle morphology.

PURPOSE: Scaphoid fractures are classified according to their 2-dimensional radiographic appearance, and transverse waist fractures are considered the most common. Our hypothesis was that most scaphoid fractures are not perpendicular to the longitudinal axis of the scaphoid (ie, not transverse). METHODS: Computerized 3-dimensional analyses were performed on 124 computed tomography scans of acute scaphoid fractures. Thirty of the fractures were displaced and virtually reduced. The angle between the scaphoid's first principal axis (longitudinal axis) and the fracture plane was analyzed for location and displacement. The distal radius articular surface was used to depict the volar-dorsal vector of the wrist. RESULTS: There were 86 fractures of the waist, 13 of the distal third, and 25 of the proximal third. The average angle between the scaphoid longitudinal axis and the fracture plane was 53° for all fractures and 56° for waist fractures, both differing significantly from a 90°, transverse fracture. The majority of fracture planes were found to have a volar distal to dorsal proximal (horizontal oblique) inclination relative to the volar-dorsal vector. CONCLUSIONS: Most waist fractures were horizontal oblique and not transverse. According to these findings, fixation of all fractures along the longitudinal axis of the scaphoid may not be the optimal mode of fixation for most. A different approach may be needed in accordance with the fracture plane. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

Stenosing flexor tenosynovitis: Validity of standard assessment tools of daily functioning and quality of life.

STUDY DESIGN: Cross-sectional. INTRODUCTION: Stenosing flexor tenosynovitis (SFT) is a common hand disease, yet there is a lack of valid standard assessments for this population. PURPOSE OF THE STUDY: Validation of assessment for the evaluation of disability and quality of life related to SFT clinical severity. METHODS: Sixty five participants with SFT were matched to 71 controls. Participant's symptoms were graded using the Quinnell classification. Disability and quality of life were evaluated using the DASH and WHOQOL-BREF questionnaires. RESULTS: Small to moderate correlations were found between SFT grade and the DASH and WHOQOL-BREF. Both questionnaires differentiated between the first and third clinical grades and between SFT and healthy groups. DISCUSSION: Both questionnaires are useful tools to distinguish between participants with SFT and controls and between mild and severe clinical grades. CONCLUSION: The DASH and WHOQOL-BREF may be implemented in the clinical management and research of SFT. LEVEL OF EVIDENCE: Diagnostic III.

Hand surgery for dystrophic epidermolysis bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is a group of inherited, mechanobullous disorders caused by mutations in various structural proteins in the skin. The manifestation of these disorders in the hand is of digital contractures and pseudosyndactyly or "cocoon hands," causing significant functional impairment.Our preferred surgical treatment of these patients involves separation of the digits from the palm by releasing the finger flexion contractures and separating them, primarily the adducted thumb. However, recurrence is common. Our hypothesis was that functional improvement is gained irrespective of recurrence of contractures. METHODS: We retrospectively evaluated 4 patients, 2 male and 2 female, whose average age was 11 years, treated surgically by the separation of all their digits and by coverage with skin grafts. The follow-up period was between 1 and 3½ years. RESULTS: Partial recurrence of the deformity was observed in all patients. Recurrence was more pronounced in the nondominant hand, especially between the digits and of flexion contractures, but did not preclude the use of precision or oppositional pinch at final follow-up. The patient with the longest follow-up has been referred for revision surgery to gain further release of contractures.Significant rehabilitation goals were achieved in all 4 patients after surgery. After 6 months, both of the younger patients were measured for finger dexterity, which showed lower scores than the norm, although this was felt to be dependent on which daily manual activities they were more familiar with. These tests could not have been performed before surgery. CONCLUSIONS: All patients and families felt the effort was worthy. Separating the thumb and straightening the digits was found to be significant, yet the indication for separating all the digits is debatable. The need for revision surgery, to maintain the digit function, is clear. LEVEL OF EVIDENCE: Level 4, case series.

The Relationship between Structure of the Wrist and Function in a Japanese and Caucasian Population.

Background: Factors such as age and joint structure affect normal wrist motion. The midcarpal joint participates in flexion/extension, radial-ulnar/deviation (RUD), and since lunate/wrist type-2 is likely more stable than a lunate/wrist type-1, we suggest that midcarpal joint structure will affect wrist motion. Our purpose was to compare wrist motion in Caucasian and Japanese populations and to associate motion with midcarpal joint morphology. We hypothesised that radiographic structure would correlate with wrist motion. Methods: A total of 164 patients with normal wrist radiographs were included. Clinical measurements included wrist extension, flexion and RUD. Radiographic measurements included the radiocarpal joint: ulnar variance, radial height, radial inclination, volar inclination and carpal joint measurements: lunate type, capitate circumference and each of its joints contact measured and calculated as a proportion of capitate circumference. Results: The groups differed in wrist motion and in multiple radiographic measurements. When the two populations were analysed together, there were no significant associations between midcarpal joint type and wrist motion. The radiocarpal joint: ulnar variance was correlated with extension and radial deviation. Radial height was directly related to flexion, and both radial height and radial inclination were directly correlated with ulnar deviation. The intracarpal measurements: The main measurement affecting motion was the contact between the capitate and the scaphoid (as a proportion of capitate circumference) with lesser correlations of the contact of the capitate with the trapezoid and hamate. The most significant measurement associated with a lunate type-2 was scaphoid contact with the capitate p = 0.01. Logistic regression demonstrated that the measurements most associated with wrist motion were scaphoid contact with the capitate/capitate circumference and hamate contact with the capitate/capitate. Conclusions: This study supports discrepancies in wrist motion amongst different racial cohorts, and a relationship between bone/joint structure in the wrist and wrist motion. This can help treat wrist pathology. Level of Evidence: Level III (Diagnostic).

Comparative outcome of bomb explosion injuries versus high-powered gunshot injuries of the upper extremity in a civilian setting.

BACKGROUND: Explosion injuries to the upper extremity have specific clinical characteristics that differ from injuries due to other mechanisms. OBJECTIVES: To evaluate the upper extremity injury pattern of attacks on civilian targets, comparing bomb explosion injuries to gunshot injuries and their functional recovery using standard outcome measures. METHODS: Of 157 patients admitted to the hospital between 2000 and 2004, 72 (46%) sustained explosion injuries and 85 (54%) gunshot injuries. The trauma registry files were reviewed and the patients completed the DASH Questionnaire (Disabilities of Arm, Shoulder and Hand) and SF-12 (Short Form-12) after a minimum period of 1 year. RESULTS: Of the 157 patients, 72 (46%) had blast injuries and 85 (54%) had shooting injuries. The blast casualties had higher Injury Severity Scores (47% vs. 22% with a score of > 16, P = 0.02) and higher percent of patients treated in intensive care units (47% vs. 28%, P = 0.02). Although the Abbreviated Injury Scale score of the upper extremity injury was similar in the two groups, the blast casualties were found to have more bilateral and complex soft tissue injuries and were treated surgically more often. No difference was found in the SF-12 or DASH scores between the groups at follow up. CONCLUSIONS: The casualties with upper extremity blast injuries were more severely injured and sustained more bilateral and complex soft tissue injuries to the upper extremity. However, the rating of the local injury to the isolated limb is similar, as was the subjective functional recovery.

Immune system augmentation by glatiramer acetate of peripheral nerve regeneration-crush versus transection models of rat sciatic nerve.

Immune system augmentation, using the antigen glatiramer acetate (GA), which is known to affect cellular immunity, has been shown to have a positive effect on peripheral nerve regeneration. We aimed to compare the effect of GA on the regeneration of crushed versus transected nerves. Wild-type rats underwent crush or transection and repair of the sciatic nerve. They were examined 3 weeks postinjury histologically (axon count) and functionally (tibialis anterior muscle weight and footprint analysis). GA was found to augment regeneration both histologically and functionally. In the transected nerve, a significant increase in axon count distal to the injury site was seen in the GA group versus control. A similar yet statistically insignificant trend was found in the crushed nerve. Improvement was found in the footprint analysis between the GA and control groups in both crush and transected nerve groups. We found improvement in the footprint analysis in the crush versus transection group. GA was found to improve the regeneration of the peripheral nerve. Histologically, this was more pronounced in the transection injury. The discrepancy between the different functional measures examined may be explained by the distance of the reinnervated muscles evaluated from the injury site.

Occupational hand trauma - Mechanism of injury and transient risk factors in Jerusalem.

INTRODUCTION: Although prevalent, and variable geographically, there is little information on the incidence and risk factors for occupation hand trauma in our health care system. This pilot study was designed to determine the optimal data collection methods for transient risk factors locally METHODS: All adult patients with occupational hand trauma treated at an emergency department (ED) during a three-month period were interviewed, either in person or by phone, using a case crossover designed questionnaire, regarding occupation and exposure to potential transient risk factor. RESULTS: Of 206 patients treated with occupational trauma during the study period, 94 had trauma distal to the elbow (46%). Patient compliance was high - 89% of the patients consented to phone interviews and 83% completed in-person ED interviews. In the 75 patients which participated in the study, several risk factors were found to be significant, including machine maintenance and being distracted, including by a cellular phone. We found lack of job experience, limited training on the job site and reports of previous injuries in these workplaces to be prevelent. DISCUSSION: The risk factors implicated in this study are similar to those reported in previous studies at other locations and are modifiable although this is the first report linking cellular phone use and occupation trauma. This finding should be further examined in a larger group and according to occupational categories. Compliance with the study was high, in person or with phone interviews, making these options viable for further studies. Several minor changes to the questionnaire were suggested although it did conform with the case-crossover study design. According to this study, standard preventive measures may be lacking in Jerusalem and should be implemented more uniformly, including specific workplace safety plans and education and taking into consideration the risk factors documented here.

Failure Rate and Early Complications of Thumb Carpometacarpal Joint Replacement-A Multicenter Retrospective Study of Two Modern Implant Designs.

Joint replacement arthroplasty for the treatment of thumb osteoarthritis is gaining popularity as recent studies have demonstrated better pinch and grip strength and faster rehabilitation. Our aim was to identify early complications in modern implant designs using a multicenter study. A total of 381 patients who underwent thumb carpometacarpal replacement surgery in six participating hospitals were enrolled. The complications included were fractures, dislocations, infections, tendon and nerve injuries, and complex regional pain syndrome. Major complications were defined as a failure to implant the prosthesis, revision surgery to remove the implant, and any other need for further surgical intervention. The secondary outcomes were any other complications treated non-surgically and the timing of the complications. Eleven procedures failed, and these patients were treated with trapeziectomies. Twelve other patients required repeat surgical interventions. Minor adverse events occurred in 25.4% of the cases, and transient irritation of the superficial radial nerve and De Quervain tendinopathy were the most prevalent complications. Although this cohort depicted the learning curves of multiple surgeons, our study demonstrated low short-term failure rates. An inability to achieve primary stability of the cup in the trapezium was the leading cause of failure. Dislocations and other major complications with modern implants were very few.

Insights and trends review: the role of three-dimensional technology in upper extremity surgery.

The use of three-dimensional (3-D) technology in upper extremity surgery has the potential to revolutionize the way that hand and upper limb procedures are planned and performed. 3-D technology can assist in the diagnosis and treatment of conditions, allowing virtual preoperative planning and surgical templating. 3-D printing can allow the production of patient-specific jigs, instruments and implants, allowing surgeons to plan and perform complex procedures with greater precision and accuracy. Previously, cost has been a barrier to the use of 3-D technology, which is now falling rapidly. This review article will discuss the current status of 3-D technology and printing, including its applications, ethics and challenges in hand and upper limb surgery. We have provided case examples to outline how clinicians can incorporate 3-D technology in their clinical practice for congenital deformities, management of acute fracture and malunion and arthroplasty.

A global perspective on gun violence injuries.

INTRODUCTION AND DEFINITIONS: Civilian gunshot violence is a growing public health issue on a global scale. Treatment of patients with gunshot injuries is based on algorithms derived from military studies, but the distinct differences in weaponry, energy of injury, timing and type of care, and environment translate to a gap in knowledge. With a focus on non-accidental gunshot trauma and excluding suicide etiologies, we propose to build a collaborative research group to address important questions focused on best practices for gunshot injury patients. PRE-HOSPITAL CARE: There are important differences in the care of gunshot victims across the globe; some countries provide advanced interventions in the field and others deliver basic support until transport to a higher level of care in hospital. Some simple interventions include the use of extremity tourniquets and intravenous fluid support; others to consider are tranexamic acid, whole blood, and hemostatic agents. ACUTE TREATMENT: Control of exsanguinating hemorrhage is a key priority for gunshot injuries. Military doctrine has evolved to prioritize exsanguination over airway or breathing as the critical first step. The X-ABC protocol focuses on exsanguinating hemorrhage, then standard evaluation of Airway, Breathing and Circulation (ABCs) to enhance survival in trauma patients. The timing of bony stabilization, in terms of damage-control vs definitive care, needs further study in this population, as does use of antibiotics for bony extremity injuries. Finally, recognition of the mental health effects of gun trauma, including post-traumatic stress disorder (PTSD), anxiety disorders, substance abuse and depression is important in advocating for prevention such as implementation of social support and specific interventions. DEFINITIVE CARE: The need for abdominal closure after exploratory laparotomy, definitive fracture treatment, and other treatment all contribute to length of stay for gunshot injured patients. Optimizing stabilization allows earlier mobilization and decreases nosocomial complications. Nerve injuries are often a source of long-term disability and their evaluation and treatment require further investigation. RESOURCES AND ETHICS: There are growing numbers of mass-casualty gunshot events, which require consideration of how to organize and use resources for treatment, including staff, operating room access, blood products, and order of treatment. Drills and planning for incident command hierarchy and communication are key to optimizing resource utilization. The ethics of choosing treatment priorities and resources are important considerations as well.

Optimal fixation of oblique scaphoid fractures: a cadaver model.

PURPOSE: Acute scaphoid fractures are commonly fixed with headless cannulated screws positioned in the center of the proximal fragment. Central placement of the screw may be difficult and may violate the scaphotrapezial joint. We hypothesize that placement of the screw through the scaphoid tuberosity will achieve perpendicular fixation of an oblique waist fracture and result in more stable fixation than a screw in the center of the proximal fragment. METHODS: We designed oblique osteotomies for 8 matched pairs of cadaver scaphoids and fixed each specimen with a headless cannulated screw. In 1 specimen, we positioned the screw at the center of the proximal fragment; we placed its matched pair perpendicular to the fracture. The perpendicular screw was directed through the scaphoid tuberosity. We placed the specimen under the increasing load of a pneumatically driven plunger. We compared stiffness, load, distance at failure, and mechanism of failure between the central and perpendicular screw groups. RESULTS: We found no difference between groups. Stiffness was identical in both groups (131 N/mm) and load to failure was similar (central screw, 137 N vs perpendicular screw, 148 N). CONCLUSIONS: In this biomechanical model of an unstable scaphoid fracture, we found that similar stability of fixation had been achieved with a screw perpendicular to the fracture plane with entry through the tuberosity, compared with a screw in a central position in the proximal fragment. This study suggests that placing the screw through the tuberosity, perpendicular to a short oblique fracture, will not impair fixation stability. CLINICAL RELEVANCE: Percutaneous fixation of scaphoid fractures has become popular although it is technically challenging. An easier distal approach through the tuberosity, without violating the scaphotrapezial joint, may not impair the fixation stability of an oblique fracture.

Treatment of upper extremity palsies, gunshot wounds and scaphoid nonunion: my preferred approaches.

The article reviews key considerations and our preferred methods in treating upper extremity palsies, gunshot wounds and scaphoid nonunion. For these three difficult conditions, I highlight the importance of a team approach when treating upper extremity neuromuscular disease, flexibility and creativity when treating gunshot wounds, and my personal protocol for dealing with scaphoid fracture nonunions.Level of evidence: V.

Nationwide community based emergency centers reveal scale of hand trauma.

INTRODUCTION: This study describes the characteristics of hand trauma treated in community-based emergency centers (CBECs) in Israel. It was hypothesized that the rate of hand trauma, as well as patient and injury characteristics, would differ from a recent study of patients treated in hospital emergency departments (EDs) in Jerusalem. METHODS: Data on all hand injury patients treated at any of the CBECs belonging to a large nationwide chain in 2017 were retrieved from the electronic medical records of the treatment centers, including demographic and clinical characteristics. RESULTS: Over the course of 2017, 53,574 individuals were treated for forearm, wrist and hand injuries (35% of all trauma patients treated during this period). The majority of the patients were male (62%). Contusions and fractures were common (80%) with a minority of lacerations (10%). Crush injuries and amputations were rare. Dog bites accounted for 1.5% of the injuries under the age of 10. Females were treated more with painkillers and opioids, especially over the age of 65, with variability between centers. Although the rate of fractures was similar between teens and the elderly, the elderly were treated with immobilization less frequently, and were referred to EDs for further care. Hospital referral rates differed significantly between centers. DISCUSSION: A higher rate of hand trauma was found in the CBECs in comparison to the hospital ED report (35% vs. 20% of all trauma patients, respectively). Patients treated at the CBECs, in comparison to the ED, were less often male, less often young adults, and differed in terms of type of injury. In the CBECs there were more contusions, as well as fewer lacerations and open wound injuries. In contrast, dog bites in children were found to be much more prevalent than previously reported. Hospital referral indications, the use of immobilization and pain management were found to vary according to age, gender and treatment center. Due to the high rate of hand trauma in CBECs, specific protocols are needed for these patients. The use of opioids should be specifically addressed, considering recent changes in treatment protocols. Thus, the prevalence and characteristics of hand trauma may be biased in studies based on hospital records.
