The Effect of Malnutrition on Postoperative Complications Following Surgery for Distal Radius Fractures.

PURPOSE: Malnutrition is known to negatively affect outcomes after arthroplasty, hip fracture, and spine surgery. Although distal radius fracture surgery may be considered in a similar patient cohort, the effect of malnutrition in this scenario is unknown. We hypothesized that admission serum albumin level, as a marker for malnutrition, would correlate with the rate of postoperative complications following surgery for distal radius fracture. METHODS: We performed a retrospective cohort study of the American College of Surgeons National Surgery Quality Improvement database. Patients undergoing open reduction and internal fixation of a distal radius fracture were identified using Current Procedural Terminology codes. We excluded patients who were septic at presentation, were multiply injured, or had open fractures. We collected patient demographics, length of stay, 30-day complications, reoperation, and readmission rates. We performed multivariable linear regression analysis controlling for age, sex, body mass index, operative time, discharge destination, and modified Frailty Index score. RESULTS: We identified 1,989 patients (mean age, 56 years; range, 18-90 years) with available albumin levels, and 14.7% had hypoalbuminemia (albumin, < 3.5 g/dL). Multivariable regression revealed that malnourished patients had higher rates of postoperative complications (6.5% vs 1.3%; odds ratio [OR] 4.88; 95% confidence interval [95% CI], 2.47-9.66). Specifically, these patients had increased rates of Clavien-Dindo IV (life-threatening) complications (2.4% vs 0%), readmission (7.2% vs 2%; OR, 3.37; 95% CI, 1.88-6.03), and mortality (1.7% vs 0.1%; OR, 9.23; 95% CI, 1.55-54.87). Malnourished patients had significantly longer length of stay (3.55 vs 0.73 days). Albumin concentration was inversely associated with risk of death (OR, 0.12; 95% CI, 0.03-0.52). CONCLUSIONS: Malnutrition, indicated by albumin less than 3.5 g/dL, is a powerful predictor of uncommon, but important, postoperative complications, including mortality, following surgery for distal radius fracture. Evaluation of preoperative albumin level may, therefore, help surgeons provide individualized counseling and more accurately stratify the risk of patients.

The Multidisciplinary Approach to the Diagnosis and Management of Nonobstetric Traumatic Brachial Plexus Injuries.

OBJECTIVE: Nonobstetric traumatic brachial plexus injuries can result in significant morbidity and chronic disability if not managed in a timely manner. Functional arm recovery is possible, but it requires a multidisciplinary approach toward the diagnosis and management of such injuries. CONCLUSION: This article provides an overview of the clinical, electrophysiology, and diagnostic imaging knowledge needed for accurate imaging interpretation and to participate in multidisciplinary discussions aimed at expediting optimal patient management.

Use of a 5-Item Modified Frailty Index for Risk Stratification in Patients Undergoing Surgical Management of Distal Radius Fractures.

PURPOSE: Compared with cast treatment, surgery may expose patients with distal radius fractures to undue risk. Surgical intervention in this cohort may offer less benefit than previously thought and appropriate patient selection is imperative. The modified Frailty Index (mFI) predicts complications after other orthopedic surgeries. We hypothesized that this index would predict, and might ultimately prevent, complications in patients older than 50 years with distal radius fractures. METHODS: We retrospectively reviewed the American College of Surgeons-National Surgery Quality Improvement Program (ACS-NSQIP) database, including patients older than 50 years who underwent open reduction and internal fixation of a distal radius fracture. A 5-item mFI score was then calculated for each patient. Postoperative complications, readmission and reoperation rates, as well as length of stay (LOS) were recorded. Bivariate and multivariable statistical analysis was then performed. RESULTS: We identified 6,494 patients (mean age, 65 years). Compared with patients with mFI of 0, patients with mFI of 2 or greater were nearly 2.5 times as likely to incur a postoperative complication (1.7% vs 7.4%). Specifically, the rates of Clavien-Dindo IV, wound, cardiac, and renal complications were increased significantly in patients with mFI of 2 or greater. In addition, as mFI increased from 0 to 2 or greater, 30-day reoperation rate increased from 0.8% to 2.4%, 30-day readmission from 0.8% to 4.6%, and LOS from 0.5 days to 1.44 days. Frailty was associated with increased complications as well as rates of readmission and reoperation even when controlling for demographic data, LOS, and operative time. Age alone was not significantly associated with postoperative complications, readmission, reoperation, or LOS. CONCLUSIONS: A state of frailty is highly predictive of postoperative complications, readmission, reoperation, and increased LOS following open reduction and internal fixation of distal radius fractures. Our data suggest that a simple frailty evaluation can help inform surgical decision making in patients older than 50 years with distal radius fractures.

The hand surgery fellowship application process: expectations, logistics, and costs.

PURPOSE: To investigate expectations, logistics, and costs relevant to the hand surgery fellowship application process. We sought to discover (1) what both applicants and program directors are seeking, (2) what both parties have to offer, (3) how both parties collect information about each other, and (4) the costs incurred in arranging each match. METHODS: We conducted on-line surveys of hand surgery fellowship applicants for appointment in 2015 and of current fellowship program directors. RESULTS: Sixty-two applicants and 41 program directors completed the survey. Results revealed applicants' demographic characteristics, qualifications, method of ranking hand fellowship programs, costs incurred (both monetary and opportunity) during the application process, ultimate match status, and suggestions for change. Results also revealed program directors' program demographics, rationale for offering interviews and favorably ranking applicants, application-related logistical details, costs incurred (both monetary and opportunity) during the application process, and suggestions for change. CONCLUSIONS: Applicants for hand surgery fellowship training are primarily interested in a potential program's academic reputation, emphasis on orthopedic surgery, and location. The typical, successfully matched applicant was a 30-year-old male orthopedic resident with 3 publications to his credit. Applicants rely on peers and Web sites for information about fellowships. Fellowship directors are primarily seeking applicants recommended by other experienced surgeons and with positive personality traits. The typical fellowship director offers a single year of orthopedic-based fellowship training to 2 fellows per year and relies on a common application and in-person interviews to collect information about applicants. Applicants appear to be more concerned than directors about the current state of the match process. Applicants and directors alike incur heavy costs, in both dollars and opportunity, to arrange each match. A nuanced understanding of the match process suggests specific changes and may help reduce these costs. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic and decision analysis V.

Management of adult diaphyseal both-bone forearm fractures.

Simultaneous diaphyseal fractures of the radius and ulna, often referred to as both-bone forearm fractures, are frequently encountered by orthopaedic surgeons. Adults with this injury are typically treated with open reduction and internal fixation because of the propensity for malunion of the radius and ulna and the resulting loss of forearm rotation. Large case series support the use of plate and screw fixation for simple fractures. More complex fractures are managed according to strain theory, with the intention of controlling rather than eliminating motion at the fracture site. This can be achieved with flexible plate and screw constructs or intramedullary nails. In general, results of surgical fixation have been good, with only modest losses of forearm strength and rotation. Notable complications include nonunion, malunion, and refracture after device removal.

The biomechanical stability of salvage procedures for distal radioulnar joint arthritis.

PURPOSE: To test distal forearm stability after 3 surgical procedures for distal radioulnar joint (DRUJ) arthritis. METHODS: We tested 11 cadaver limbs with the DRUJ intact, after distal ulna-matched hemiresection, after Darrach distal ulna resection, and after unlinked total DRUJ arthroplasty. We evaluated distal forearm stability in neutral rotation, full pronation, and full supination in unweighted and 1-kg-weighted conditions. We measured dorsal/palmar translation and convergence/divergence of the distal radius relative to the ulna. RESULTS: Under neutral rotation, whether weighted or unweighted, matched hemiresection and Darrach specimens demonstrated significant radioulnar convergence relative to intact specimens. Weighted and unweighted, DRUJ arthroplasty demonstrated similar radioulnar convergence to intact. Weighted and unweighted, only Darrach specimens showed significant radius-palmar translation compared with intact, hemiresected, and DRUJ arthroplasty. In pronation, no testing scenario, either weighted or unweighted, demonstrated statistically significant radioulnar convergence relative to intact state. In unweighted pronation, palmar translation of the radius was significantly different from the intact state for all surgical scenarios and the Darrach was significantly worse than the other procedures. In weighted pronation, palmar translation of the radius was significantly different from the intact state for all surgical scenarios and the matched hemiresection was significantly better than the other procedures. In supination, weighted and unweighted, Darrach specimens had significant radioulnar convergence relative to intact. Either weighted or unweighted, the hemiresection and arthroplasty groups demonstrated similar radioulnar convergence relative to intact. Unweighted, all scenarios demonstrated similar dorsal translation of the radius. Weighted, the Darrach group showed significant radius-dorsal translation relative to intact specimens. CONCLUSIONS: For tested procedures, DRUJ arthroplasty overall was biomechanically superior to the other conditions except that we found greater stability in the hemiresected group in weighted pronation. CLINICAL RELEVANCE: Knowledge of baseline biomechanical characteristics of DRUJ arthritis procedures will aid surgical decision-making and patient counseling.

Hand fractures: a review of current treatment strategies.

Fractures of the tubular bones of the hand are common and potentially debilitating. The majority of these injuries may be treated without an operation. Surgery, however, offers distinct advantages in properly selected cases. We present a review of hand fracture management, with special attention paid to advances since 2008. The history and mechanisms of these fractures are discussed, as are treatment options and common complications. Early mobilization of the fractured hand is emphasized because soft tissue recovery may be more problematic than that of bone.

Intramedullary Screw Fixation of Olecranon Fractures Reduces the Risk of Early Unplanned Reoperation: A Retrospective Review of 556 Patients.

OBJECTIVES: To determine the effect of intramedullary screw-based fixation on early postoperative complications after olecranon fractures. We hypothesized that intramedullary screw-based fixation results in decreased need for reoperation compared with plate and screw-based and tension band-based fixation. DESIGN: Retrospective cohort. SETTING: Two academic Level-1 trauma centers. PATIENTS/PARTICIPANTS: Five hundred fifty-six patients treated with a tension band-based, plate and screw-based, or intramedullary screw-based construct for an olecranon fracture over a 10-year period. INTERVENTION: Open reduction and internal fixation. MAIN OUTCOME MEASUREMENT: Unplanned reoperation. Demographic, injury type and severity, supplemental fixation, and length of follow-up data were viewed as potential confounders and analyzed as such. RESULTS: We identified 556 relevant patients. One hundred ninety-nine patients were treated with an intramedullary screw-based construct, 229 with a plate and screw-based construct, and 128 with a tension band-based construct. We observed significant differences in the age, fracture type, percentage of open fractures, use of supplemental fixation, and treating institution between the treatment groups. Ninety-five patients (17.1%) had an unplanned reoperation. When we adjusted for confounders, intramedullary screw-based fixation reduced the odds of an unplanned reoperation by 54% compared with plate and screw-based treatment. In the adjusted analysis, we did not observe a difference between plate and screw-based treatment and tension band-based fixation. CONCLUSIONS: Intramedullary screw-based fixation of olecranon fractures results in decreased need for early reoperation compared with more common olecranon fixation strategies. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Origins of eponymous orthopaedic equipment.

BACKGROUND: Orthopaedists make great use of eponymous equipment, however the origins of these tools are unknown to many users. This history enriches, enlightens, and enhances surgical education, and may inspire modern innovation. QUESTIONS/PURPOSES: We explored the origins of common and eponymous orthopaedic equipment. METHODS: We selected pieces of equipment named for their inventors and in the broadest use by modern orthopaedists. We do not describe specialized orthopaedic implants and instruments owing to the overwhelming number of these devices. RESULTS: The history of this equipment reflects the coevolution of orthopaedics and battlefield medicine. Additionally, these stories evidence the primacy of elegant design and suggest that innovation is often a process of revision and refinement rather than sudden inspiration. Their history exposes surgical innovators as brilliant, lucky, hardworking, and sometimes odd. These stories amuse, enlighten, and may inspire modern orthopaedists to develop creative solutions of their own. CONCLUSIONS: The rich history of the field's eponymous instruments informs an ongoing tradition of innovation in orthopaedics.

Four Ways Plastic Surgeons Can Fight Climate Change.

The climate crisis demands that surgeons reduce their environmental impact. Operating rooms are resource-intensive and are often wasteful. This makes them fitting targets for climate-conscious decision making. METHODS: We searched for peer-reviewed literature describing how plastic surgeons might positively affect the environment through action in the operating room. RESULTS: Several evidence-based, pro-climate practices may be undertaken by plastic surgeons. These strategies may be grouped into 4 types: material, energy, technique, and dissemination. Each strategy is a way to reduce, reuse, recycle, research, or rethink. CONCLUSIONS: Administrative obstacles to greener operating rooms are predictable and surmountable, especially because environmentally minded decisions are likely to save money. We anticipate a surge of environmental consciousness in healthcare. Plastic surgeons, as thought leaders, are well positioned to champion this cause.

Acute care surgery after renal transplantation.

Emergent operation after renal transplantation (RT) has traditionally been associated with substantial morbidity and mortality. We reviewed 2340 adult patients who underwent RT at our tertiary care center and identified 55 patients who required acute care surgical consultation within 1 year of transplantation. Of these, 43 were treated operatively and 12 nonoperatively. Primary diagnoses were intestinal problems in 29 patients (53%), including diverticulitis, ischemia, perforation, obstruction, and bleeding; cholecystitis in 10 (18%); fluid collections in six (11%), appendicitis and hernias in two each (4%); gastritis in one (2%); and no diagnosis in five (9%). Colonic pathology was treated with resection and diversion in 14 of 16 patients who underwent surgery. Acute allograft rejection preceded the surgical problem in five patients. Complications occurred in 13 per cent of patients, and mortality was 9 per cent. Colonic ischemia had a fulminating presentation and particular morbidity. We conclude that acute gastrointestinal emergencies after RT are rare and that early and aggressive intervention using an acute care surgical model yields excellent results.

Ten Tips to Simplify the Spaghetti Wrist.

Hand surgeons refer to deep lacerations of the volar distal forearm as "spaghetti wrists." Given that multiple tendons, vessels, and nerves often require repair, this injury may be intimidating. We review management of spaghetti wrists and summarize with 10 simplifying tips.

Computed tomographic analysis of the internal structure of the metacarpals and its implications for hand use, pathology, and surgical intervention.

The variation of bone structure and biomechanics between the metacarpals is not well characterized. It was hypothesized that their structure would reflect their common patterns of use (i.e., patterns of hand grip), specifically that trabecular bone density would be greater on the volar aspect of all metacarpal bases, that this would be most pronounced in the thumb, and that the thumb diaphysis would have the greatest bending strength. Cross-sections at basal and mid-diaphyseal locations of 50 metacarpals from 10 human hands were obtained by peripheral quantitative computed tomography. The volar and dorsal trabecular densities of each base were measured and characterized using the volar/dorsal density ratio. The polar stress-strain index (SSIp), a surrogate measure of torsional/bending strength, was measured for each diaphysis and standardized for bone length and mass. Comparisons were made using mixed-model analyses of variance (ANOVAs) and post hoc tests. Volar/dorsal trabecular density ratios showed even distribution in all metacarpal bases except for the thumb, which showed greater values on the volar aspect. The thumb, second, and third metacarpals all had high bending strength (SSIp), but the thumb's SSIp relative to its length and trabecular mass was much higher than those of the other metacarpals. Trabecular density of the metacarpal bases was evenly distributed except in the thumb, which also showed higher bending strength relative to its length and mass. Understanding of how these indicators of strength differ across metacarpals may improve both fracture diagnosis and treatment and lays the groundwork for investigating changes with age, hand dominance, and occupation.

Viability of Hand and Wrist Photogoniometry.

BACKGROUND: No goniometric technique is both maximally convenient and completely accurate, although photogoniometry (ie, picture taking to facilitate digital angle measurement) shows promise in this regard. Our purpose was to test the feasibility and reliability of a photogoniometric protocol designed to measure wrist and digit range of motion in general. METHODS: Two independent observers examined a sample of joints in both normal and abnormal hands according to a photogoniometric protocol. Interrater and intrarater correlation were calculated, and these measurements were compared with measurements made by a third independent examiner with a manual goniometer. RESULTS: The photo-based measurements were reliable within and between observers; however, only a minority of these measurements were in agreement with manually collected values. CONCLUSIONS: At present, photogoniometry is not an acceptable alternative to manual goniometry for determining wrist and digit range of motion in general. Joint-specific photogoniometry should be the subject of future study, as should relevant imaging and software technology.

Ulnar Artery Aneurysm in a 6-Month-Old: A Case Report.

BACKGROUND: Pediatric ulnar aneurysms are rare and, unlike their adult counterparts, cannot be explained by repetitive trauma to the palm. A small number of case reports describe diagnostic difficulty with these lesions and different treatments. METHODS: We present the case of a 6-month-old with an ulnar artery aneurysm of unknown cause. The diagnosis was supported with magnetic resonance imaging, and the lesion was resected. RESULTS: Because the hand remained well perfused, the ulnar artery was not reconstructed. CONCLUSIONS: Although the early result was good, the long-term outcome of this approach is unknown.

Efficient Construction of Volar Wrist Splints: A Biomechanical Study Comparing Splints of Different Material, Thickness, and Design.

Background: The aim was to test the null hypothesis that splint material, thickness, or longitudinal ridging does not affect the strength of a wrist splint. Methods: Ten splints were made according to each of 7 different splint designs (resulting in 7 groups of 10 splints each). All splints were the same length and were molded to approximate the contour of the volar hand, wrist, and forearm with the wrist in neutral. Three groups consisted of plaster splints of different thicknesses (8, 10, and 12 ply). Three additional groups included splints of the same thicknesses but with a longitudinal ridge. A single group was constructed from prefabricated fiberglass splinting material and did not involve a longitudinal ridge. Five splints in each group were subjected to 3-point bending mimicking flexion of the wrist and 5 were subjected to a 3-point bend mimicking wrist extension. Splints were loaded to failure using a servohydraulic load frame. Analysis of variance was used to compare splints. Results: Among the plaster splints, more layers of material and longitudinal ridging increased splint strength. Ridged 8-ply plaster splints exceeded the strength of nonridged 10-ply plaster splints. Ridged 8-ply plaster splints were similar in strength to fiberglass splints. Conclusions: The 8-ply ridged plaster splints may be a lighter, effective, and cheaper alternative to more common splint designs.
