Upper Extremity Tendon Transfers: A Brief Review of History, Common Applications, and Technical Tips.

Background Tendon transfer in the upper extremity represents a powerful tool in the armamentarium of a reconstructive surgeon in the setting of irreparable nerve injury or the anatomic loss of key portions of the muscle-tendon unit. The concept uses the redundancy/expendability of tendons by utilizing a nonessential tendon to restore the function of a lost or nonfunctional muscle-tendon unit of the upper extremity. This article does not aim to perform a comprehensive review of tendon transfers. Instead it is meant to familiarize the reader with salient historical features, common applications in the upper limb, and provide the reader with some technical tips, which may facilitate a successful tendon transfer. Learning Objectives (1) Familiarize the reader with some aspects of tendon transfer history. (2) Identify principles of tendon transfers. (3) Identify important preoperative considerations. (4) Understand the physiology of the muscle-tendon unit and the Blix curve. (5) Identify strategies for setting tension during a tendon transfer and rehabilitation strategies. Design This study was designed to review the relevant current literature and provide an expert opinion. Conclusions Tendon transfers have evolved from polio to tetraplegia to war and represent an extremely powerful technique to correct neurologic and musculotendinous deficits in a variety of patients affected by trauma, peripheral nerve palsies, cerebral palsy, stroke, and inflammatory arthritis. In the contemporary setting, these very same principles have also been very successfully applied to vascularized composite allotransplantation in the upper limb.

Avascular Necrosis of the Metacarpal Head: A Review of 4 Cases.

PURPOSE: To report on 4 cases of avascular necrosis of the metacarpal head. METHODS: We retrospectively reviewed 4 patients who received a diagnosis of avascular necrosis of the metacarpal head and were treated from 2000 to 2016. RESULTS: All patients were males with involvement of the dominant hand. Three patients had a history of trauma and/or fractures in another finger and one had a history of fracture in the same finger. The diagnosis was confirmed on regular x-rays and magnetic resonance imaging. Nonsurgical management was offered to all patients (rest, placement of an orthosis, and nonsteroidal anti-inflammatory drugs) for 3 to 6 months. Two patients responded well to nonsurgical management and improved in their symptoms. One patient refused surgical intervention and continued to have persistent pain. The other patient was treated with curettage and bone graft and had total resolution of pain symptoms with full active range of motion. CONCLUSIONS: A high index of suspicion is required to diagnose and treat avascular necrosis of the metacarpal head correctly. Treatment options are numerous and require further studies to investigate their effectiveness in the treatment of this rare disease. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.

Factors Associated With Met Expectations in Patients With Hand and Upper Extremity Disorders: A Pilot Study.

PURPOSE: The degree to which patients' expectations are met during an office visit consistently correlates with patients' satisfaction, whereas the relationship between previsit expectations and satisfaction varies. OBJECTIVE: The aim of this pilot study was to preliminarily assess the relationship of psychosocial factors, pain intensity, and magnitude of disability to previsit expectations, met expectations, and satisfaction with medical care in patients with hand and upper extremity conditions in a surgical outpatient clinic. METHODS: A cohort of 85 outpatients with upper extremity illnesses indicated their previsit expectations (Patients Intention Questionnaire), degree to which these expectations were met (Expectations Met Questionnaire), level of depressive symptoms (Patient Health Questionnaire-2), confidence about the ability to achieve one's goals in spite of pain (Pain Self-Efficacy Questionnaire), pain intensity (Numerical Rating Scale for pain), disability (Disabilities of the Arm Shoulder and Hand, short version; QuickDASH), and satisfaction with the medical visit (Medical Interview Satisfaction Scale). RESULTS: Higher previsit expectations were associated with more depressive symptoms, lower pain self-efficacy, higher pain intensity, and fewer years of education. Patients in the low and moderate met expectations categories had significantly more symptoms of depression, fewer years of education, and more pain compared to those in the high-met expectations category. Fewer years of education and higher pain intensity predicted higher previsit expectations and explained 19% of variance. CONCLUSION: Psychosocial factors affect both previsit expectations and met expectations during an outpatient visit to a hand surgeon. Met expectations, but not previsit expectations, affect satisfaction. LEVEL OF EVIDENCE: Prognostic, level II.

Prevalence of and Factors Associated With Major Depression in Patients With Upper Extremity Conditions.

PURPOSE: To determine the prevalence of an estimated diagnosis of major depression in patients with upper extremity conditions and factors that help identify patients who might benefit from psychological treatment. METHODS: In this observational cross-sectional study, 190 patients completed questionnaires measuring symptoms of depression with the Patient Health Questionnaire, upper extremity disability with the Patient-Reported Outcomes Measurement Information System Upper Extremity, pain interference with the Patient-Reported Outcomes Measurement Information System Pain Interference, and health anxiety with the Short Health Anxiety Inventory. RESULTS: The estimated prevalence of an estimated diagnosis of major depression (Patient Health Questionnaire 9 ≥ 10) among this group of patients was 12%. Having multiple pain conditions, a history of depression, and greater limitation from pain for daily activities were independently associated with an estimated diagnosis of major depression. CONCLUSIONS: The finding that 1 in 8 patients presenting to a hand surgeon have untreated or undertreated symptoms of depression sufficient to qualify for an estimated diagnosis of major depression emphasizes the importance of assessing for depression at all levels of care.

Patient Satisfaction and its Relation to Perceived Visit Duration With a Hand Surgeon.

PURPOSE: To determine whether patient perception of time spent with a hand surgeon relates to patient satisfaction after a single new-patient office visit. METHODS: Prior to each visit, 112 consecutive new patients predicted how much time they expected to spend with the surgeon. Following the visit, patients were asked to estimate the time spent with the surgeon, indicate whether the surgeon appeared rushed, and rate their overall satisfaction with the surgeon. Wait time and actual visit duration were measured. Patients also completed a sociodemographic survey, the Consultation and Relational Empathy Measure, the Newest Vital Sign Health Literacy test, and 3 Patient-Reported Outcomes Measurement Information System-based questionnaires: Upper Extremity Function, Pain Interference, and Depression. Multivariable logistic and linear regression models were used to determine predictors of patient satisfaction, patient-perceived surgeon rush, and high previsit expectations of visit duration. RESULTS: Patient satisfaction was not associated with perceived visit duration but did correlate strongly with patient-rated surgeon empathy and symptoms of depression. Neither visit duration nor previsit expectations of visit length were determinants of patient-perceived surgeon rush. Only surgeon empathy was associated. Less-educated patients anticipated needing more time with the surgeon. CONCLUSIONS: Patient satisfaction with the surgeon and with the time spent during the office visit was primarily linked to surgeon empathy rather than to visit duration or previsit expectation of visit length. Efforts to make hand surgery office visits more patient-centered should focus on improving dialogue quality, and not necessarily on making visits longer.

Side-to-Side Versus Pulvertaft Extensor Tenorrhaphy-A Biomechanical Study.

PURPOSE: We hypothesized that a side-to-side (STS) tendon repair has biomechanical characteristics that match those of a Pulvertaft (PT) weave. METHODS: Thirty extensor tendons were harvested (4 extensor digitorum communis and 1 extensor indicis proprius from 6 cadaver arms). Three hand surgery fellows with similar backgrounds of training under the same conditions and precise standardized technique performed the repairs (5 PT and 5 STS per surgeon). After the repairs, the tendons were passed through a graft-sizing guide to determine bulk and results were expressed as a repaired versus native diameter ratio. The specimens were then tested for ultimate strength and fatigue properties. Failure type and mechanical properties were recorded and compared with those of the native tendon. RESULTS: The average peak force to failure was 93 ± 20 N for the STS and 62 ± 32 N for PT group. Relative strength ratio (repair strength compared with native tendon strength) was 37% ± 21% for the STS and 22% ± 11% for the PT group. In the STS group, all failures occurred as a result of tissue failure; however, in the PT, suture failures occurred in 3 tendons before tissue failure. The mean bulk ratio of the repaired site versus native proximal tendon was 37 ± 14% and 40% ± 22% more for the STS and PT groups, respectively. These values for native distal tendon were 28% ± 9.9% and 26% ±24 %, respectively for STS and PT repair. Furthermore, the bulk of the repaired site for the STS and PT groups was 4.2 ± 0.50 and 4.7 ± 1.2 mm, respectively. CONCLUSIONS: Side-to-side repair technique showed superior biomechanical properties while demonstrating comparable repair bulk of the tendon coaptation compared with the Pulvertaft weave. CLINICAL RELEVANCE: The results of this study may help guide a surgeon's choice of repair technique when addressing tendon injuries or tendon transfers.

Computed Tomography Angiography Allows the Classification of the First Dorsal Metatarsal Arteries.

Background Conventional angiography is an invasive technique. Submillimeter computed tomography angiography (CTA) has been shown to be an effective alternative for peripheral artery branches. This study aimed to assess the use of CTA to guide the choice and design of foot donor area for finger or thumb reconstruction. Methods This was a retrospective study of 79 patients who underwent finger or thumb reconstruction between January, 2011 and March, 2014. All these patients underwent preoperative CTA to determine the exact blood supply at the donor site. Preoperative imaging and intraoperative findings at the donor site were compared. Results Among the 79 patients (158 feet), 474 artery segments (dorsalis pedis artery [DPA], first dorsal metatarsal artery [FDMA], and toe web artery [TWA]) were evaluated using CTA. Image satisfaction rates of the vessels were 100.0 ± 0.0%, 89.2 ± 3.2%, and 60.1 ± 5.0% for DPA, FDMA, and TWA, respectively. Among the 158 feet, 90 were Gilbert type I (57.0%), 52 were Gilbert type II (32.9%), 13 were Gilbert type III (8.2%), and 3 were with poor visibility and could not be classified (1.9%). In all 79 patients, the CTA image of the FDMA was consistent with the intraoperative observations. All reconstructed fingers survived. Follow-up was available for 69 patients. After a 6- to 18-month follow-up, the reconstructed fingers and donor area recovered well, and the reconstructed fingers had strong holding power, without pain. Conclusion CTA can produce three-dimensional images for extremity arteries, allowing the preoperative assessment of blood supply and planning of donor site.

Intraoperative Technique for Evaluation of the Interosseous Ligament of the Forearm.

PURPOSE: To introduce a technique for the diagnosis of interosseous ligament (IOL) disruption based on lateral displacement of the radius after radial head resection and to determine the cutoff value of the lateral displacement for the diagnosis of disruption, the best elbow position for testing, and the diagnostic performance of the technique in different positions. METHODS: We used 10 fresh-frozen cadavers. After resection of the radial head, a Steinman pin was placed into the radius medullary canal and used to mark the pin location on the capitellum. We applied 1 kg force to pull the proximal radius laterally and measured the displacement in full supination, neutral, and full pronation of the forearm with the elbow in extension and then in 90° flexion. All measurements were performed once with the IOL intact and again with it cut. To assess diagnostic efficacy, receiver operating characteristics curves were constructed. To determine the quality of the technique, we measured the area under the receiver operating characteristics curve for each position. We also determined the cutoff value to obtain the highest sensitivity and specificity. RESULTS: The area under the curve of the test in extension-supination and flexion-supination showed that these positions were excellent for the diagnosis of IOL disruption. The cutoff value of 5.5 mm lateral displacement in extension-supination had 100% sensitivity and 90% specificity. In flexion-supination, the cutoff value of 9 mm had 100% sensitivity and 90% specificity for the diagnosis of IOL disruption. CONCLUSIONS: This maneuver was reliable and accurate in cadavers with complete IOL disruption. It is likely that in an intraoperative setting, these results will be reproducible. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

Health literacy in hand surgery patients: a cross-sectional survey.

PURPOSE: To determine the prevalence of and factors associated with limited health literacy among outpatients presenting to an urban academic hospital-based hand surgeon. METHODS: A cohort of 200 English- and Spanish-speaking patients completed the Newest Vital Sign (NVS) health literacy assessment tool, a sociodemographic survey, and 2 Patient-Reported Outcomes Measurement Information System-based computerized adaptive testing questionnaires: Patient-Reported Outcomes Measurement Information System Pain Interference and Upper-Extremity Function. The NVS scores were divided into limited (0-3) and adequate (4-6) health literacy. Multivariable regression modeling was used to identify independent predictors of limited health literacy. RESULTS: A total of 86 patients (43%) had limited health literacy (English-speaking: 33%; Spanish-speaking: 100%). Factors associated with limited health literacy were advanced age, lower income, and being publicly insured or uninsured. Increasing years of education was a protective factor. Primary language was not included in the logistic regression model because all Spanish-speaking patients had limited health literacy. When evaluating health literacy on a continuum, primary language was the factor that most influenced the NVS scores, accounting for 14% of the variability. CONCLUSIONS: Limited health literacy was commonplace among patients seeing a hand surgeon, more so in elderly and disadvantaged individuals. We hope our study raises awareness of this issue among hand surgeons and encourages providers to simplify messages and improve communication strategies. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Physician Empathy as a Driver of Hand Surgery Patient Satisfaction.

PURPOSE: To examine the relationship between patient-rated physician empathy and patient satisfaction after a single new hand surgery office visit. METHODS: Directly after the office visit, 112 consecutive new patients rated their overall satisfaction with the provider and completed the Consultation and Relational Empathy Measure, the Newest Vital Sign health literacy test, a sociodemographic survey, and 3 Patient-Reported Outcomes Measurement Information System-based questionnaires: Pain Interference, Upper-Extremity Function, and Depression. We also measured the waiting time in the office to see the physician, the duration of the visit, and the time from booking until appointment. Multivariable logistic and linear regression models were used to identify factors independently associated with patient satisfaction. RESULTS: Patient-rated physician empathy correlated strongly with the degree of overall satisfaction with the provider. After controlling for confounding effects, greater empathy was independently associated with patient satisfaction, and it alone accounted for 65% of the variation in satisfaction scores. Older patient age was also associated with satisfaction. There were no differences between satisfied and dissatisfied patients with regard to waiting time in the office, duration of the appointment, time from booking until appointment, and health literacy. CONCLUSIONS: Physician empathy was the strongest driver of patient satisfaction in the hand surgery office setting. As patient satisfaction plays a growing role in reimbursement, targeted educational programs to enhance empathic communication skills in hand surgeons merit consideration. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Determinants of disability after proximal interphalangeal joint sprain or dislocation.

BACKGROUND: Sprain or dislocation of the proximal interphalangeal joint may be a useful example of the counterintuitive aspects of recovery as the prognosis is excellent, but protectiveness in response to discomfort often hinders the stretching exercises that are a key component of the recovery process. OBJECTIVE: The aim of this study was to investigate the relationship between disability and pain self-efficacy in this context. METHODS: A total of 82 patients (54 men and 28 women) were enrolled in this prospective study. Finger motion was measured, and the patients completed measures of upper limb-specific disability (the shortened version of the Disabilities of the Arm, Shoulder and Hand questionnaire), symptoms of depression (Patient Health Questionnaire-9), effective coping strategies in response to pain (the Pain Self-Efficacy Questionnaire), and a pain scale at enrollment. RESULTS: Patients were enrolled a mean of 48 days after injury. The final multivariable model accounting for greater disability included lower self-efficacy, greater symptoms of depression, and gender (women have more disability). Lower self-efficacy was also the strongest predictor of pain intensity and finger stiffness. CONCLUSIONS: Effective coping strategies such as self-efficacy facilitate recovery (less disability, pain, and stiffness) after proximal interphalangeal joint sprain/dislocation. LEVEL OF EVIDENCE: Prognostic level I.

Determinants of disability after fingertip injuries.

BACKGROUND: Psychological factors, such as depression, catastrophic thinking, and self-efficacy, account for more of the variation in upper extremity disability than motion and other impairments, but their influence in the setting of hand trauma is less well studied. OBJECTIVE: The aim of this study was to determine which factors account for variation in disability 1 month after fingertip injuries. METHODS: We enrolled 82 patients with finger injuries distal to the proximal interphalangeal joint, and 70 patients completed the study. Questionnaires and measurements were taken at the initial visit and approximately 1 month later. Patients completed the short version of the Disabilities of the Arm Shoulder and Hand questionnaire, the pain self-efficacy questionnaire, and the Patient Health Questionnaire to assess depressive symptoms. Bivariate and multivariable analyses determined factors associated with QuickDASH scores. RESULTS: The mean disabilities of the arm shoulder and hand questionnaire score was 35 at the initial visit (the U.S. norm is 10) and 17 approximately 1 month later. The best model explained 54% of the variation in disabilities of the arm shoulder and hand questionnaire 1 month after injury and included symptoms of depression (Patient Health Questionnaire; partial R2 0.43) and injury mechanism (saw injury compared with sport injury; partial R2 0.14). The criterion symptoms of depression was also the factor most strongly associated with both pain intensity and time off work. CONCLUSIONS: In patients with fingertip injury, symptoms of depression account for most of the variability in hand and arm-specific disability, pain intensity, and days to return to work. Identification and treatment of symptoms of depression might facilitate recovery from fingertip injuries.

The pain self-efficacy questionnaire: validation of an abbreviated two-item questionnaire.

BACKGROUND: The Pain Self-Efficacy Questionnaire (PSEQ) is a validated tool to assess pain self-efficacy and is strongly correlated with disability. Reducing the number of questions of the original PSEQ to screen for self-efficacy will result in more efficient screening and less burden for the patient. OBJECTIVE: The aim of this study was to prospectively validate the shortened version of the PSEQ. METHOD: Overall, 249 new and follow-up patients visiting our outpatient orthopedic hand surgery clinic were prospectively enrolled and asked to complete the PSEQ, short version of the Disabilities of the Arm Shoulder and Hand, and 2-question version of the Patient Health Questionnaire (PHQ-2) depression questionnaires. The patients completed the questionnaires in the office and online 2 weeks after their visit. At the follow-up visit, the PSEQ was substituted with the 2-question version of the Pain Self-Efficacy Questionnaire (PSEQ-2). The factors associated with higher short forms of the Disabilities of the Arm, Shoulder and Hand scores were investigated in a bivariate and multivariable analysis. Paired t-test was used to compare the mean values of the short and long questionnaires at enrollment. RESULTS: There was a large correlation (r = 0.90; p < 0.001) between the original PSEQ and the PSEQ-2 at enrollment. The Cronbach α were comparable for the PSEQ and the PSEQ-2 (α = 0.95 compared with α = 0.91). There was a small but statistically significant difference between the average scores of the PSEQ and PSEQ-2 (4.4 vs 4.8; p < 0.001). For the shortened PSEQ, a smaller-but still large-correlation was found with the short forms of the Disabilities of the Arm, Shoulder and Hand (r = 0.71 vs r = 0.61). Both the PSEQ-2 and the PSEQ were the most important predictors of the short forms of the Disabilities of the Arm, Shoulder and Hand scores. A substantial test-retest reliability was found for the PSEQ-2 (0.66). CONCLUSION: The PSEQ-2 can be used to quickly assess patients׳ pain self-efficacy.

Outcomes of closed reduction and periarticular pinning of base and shaft fractures of the proximal phalanx.

PURPOSE: To review the results of periarticular pinning of extra-articular fractures of the proximal phalanx base and shaft. METHODS: A retrospective review was performed of the senior author's practice (C.S.M.) from 2006 to 2012. The inclusion criteria were patients older than 18 years of age who underwent periarticular pinning of base or shaft fractures of the proximal phalanx. Age, sex, fracture location, fracture pattern, and time to surgery were recorded. Outcome measures were range of motion, time to healing, and complication rate. RESULTS: A total of 43 patients with 50 fractures were identified. There were 19 men and 24 women with 16 shaft and 34 base fractures. Five fractures were open. The little finger was involved in 62%, the ring finger in 30%, and the index and middle fingers in 4% each. Most fractures were transverse or oblique, and just over half had comminution and/or impaction. Average follow-up was 17 weeks, and average time to clinical union was 35 days. Nine patients (18%) were lost to follow-up. Twenty-six fingers had excellent results (63%), lacking less than 10° of total motion. Seven patients (17%) had good results, lacking less than 20° of motion; 7 patients had fair results (17%); and 1 patient had a poor result. Three patients (7%) developed stiffness requiring tenolysis. There were 2 pin-site infections, 1 of which resulted in a loss of reduction. Results for shaft and base fractures were not significantly different. CONCLUSIONS: Percutaneous periarticular pinning is an acceptable option for unstable base and shaft fractures of the proximal phalanx. Most fractures healed within 4 weeks. The majority of patients had excellent or good results. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Carpal tunnel syndrome: assessment of surgeon and patient preferences and priorities for decision-making.

PURPOSE: This study tested the null hypothesis that there are no differences between the preferences of hand surgeons and those patients with carpal tunnel syndrome (CTS) facing decisions about management of CTS (ie, the preferred content of a decision aid). METHODS: One hundred three hand surgeons of the Science of Variation Group and 79 patients with CTS completed a survey about their priorities and preferences in decision making regarding the management of CTS. The questionnaire was structured according the Ottawa Decision Support Framework for the development of a decision aid. RESULTS: Important areas on which patient and hand surgeon interests differed included a preference for nonpainful, nonoperative treatment and confirmation of the diagnosis with electrodiagnostic testing. For patients, the main disadvantage of nonoperative treatment was that it was likely to be only palliative and temporary. Patients preferred, on average, to take the lead in decision making, whereas physicians preferred shared decision making. Patients and physicians agreed on the value of support from family and other physicians in the decision-making process. CONCLUSIONS: There were some differences between patient and surgeon priorities and preferences regarding decision making for CTS, particularly the risks and benefits of diagnostic and therapeutic procedures. CLINICAL RELEVANCE: Information that helps inform patients of their options based on current best evidence might help patients understand their own preferences and values, reduce decisional conflict, limit surgeon-to-surgeon variations, and improve health.

Patient activation and disability in upper extremity illness.

PURPOSE: To determine if higher patient activation (active involvement in one's health care) correlates with fewer symptoms and less disability in patients with hand and upper extremity illness. METHODS: We enrolled 112 patients presenting to our department for the first time. Before meeting with the surgeon, subjects completed a demographics questionnaire, the short form Patient Activation Measure; Quick Disabilities of the Arm, Shoulder, and Hand; Patient Health Questionnaire-2; Pain Self-Efficacy Questionnaire; and an 11-point ordinal rating of pain intensity. We contacted patients 1 to 2 months after enrollment. Seventy-five subjects completed the second evaluation over the telephone, on a secure data-collection web site, or in an office visit, which included the Patient Activation Measure; Quick Disabilities of the Arm, Shoulder, and Hand; numerical rating scale for pain; and ordinal rating of treatment satisfaction. RESULTS: Patient activation at enrollment correlated with disability, pain intensity, and satisfaction with treatment but was only retained in the multivariable model for pain intensity. Pain self-efficacy at enrollment was the factor that best accounted for variation in disability, pain, and satisfaction with treatment. CONCLUSIONS: Given the consistent relationship between effective coping strategies (eg, pain self-efficacy) and symptoms and disability and the independent influence of patient activation on pain intensity in this study, future research should address the ability of interventions that improve self-efficacy and patient activation to improve upper extremity health. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Relationships between pain misconceptions, disability, patients' goals and interpretation of information from hand therapists.

INTRODUCTION: Patient interpretation of advice from hand therapists may be related to nonadaptive pain thoughts (automatic, overprotective, unduly pessimistic statements triggered by nociception and exacerbated by psychological distress). PURPOSE OF THE STUDY: This study aimed to determine whether there were correlations between participants' hand therapy goals, interpretation of advice from hand therapists, nonadaptive pain thoughts, and upper extremity-specific disability. METHODS: One hundred and five participants completed questionnaires assessing nonadaptive pain thoughts, upper extremity-specific disability, lessons from hand therapists, and hand therapy goals. RESULTS: Nonadaptive pain thoughts correlated with disability and were bi-directionally related to participant goals and interpretation of advice from hand therapists. DISCUSSION: Patients' nonadapative pain thoughts and the words/concepts used by hand therapists are both important in recovery from upper extremity illness. CONCLUSIONS: Hand therapists should be mindful that nonadaptive pain thoughts are an important determinant of disability and that such thoughts can affect and be affected by their recommendations.

Management of isolated volar lunate facet fractures of the distal radius.

Distal radius fractures are among the most common fractures treated globally. Consideration of the mechanism of injury and careful radiographic assessment contributes to appropriate management of these injuries in isolation or jointly with other fractures or injuries affecting the wrist joint. Treatment options can range from non-operative management to a variety of fixation techniques. Interest in the distal radius fractures was renewed as open reduction and monoblock volar locking plate fixation became the preferred contemporary treatment in the last few decades. Isolated volar lunate facet (VLF) fractures are uncommon. However, the stability of the entire carpus may be compromised with fractures of the volar marginal rim. Inadequately or improperly treated fractures of the VLF can lead to significant long-term complications. A critical approach to this unique fracture pattern's evaluation, management, and surgical fixation is paramount for successful and reproducible outcomes in stability and durability.

The "Bag of Bones" Treatment of Comminuted Intra-articular Distal Humerus Fractures in the Elderly.

BACKGROUND: Extensively comminuted intra-articular distal humerus fractures in the elderly present a challenging therapeutic dilemma. The purpose of this study was to investigate the results of nonoperative treatment of these fractures in a select subset of patients. METHODS: Patients treated with nonoperative management for a comminuted intra-articular distal humerus fracture between 2007 and 2018 were reviewed. Patients were administered 3 elbow-specific functional outcomes instruments. RESULTS: A total of 8 patients (2 men, 6 women) were treated with brief immobilization followed by early range of motion. All had fractures with extensive comminution of the articular surface such that open reduction and internal fixation was not feasible. Average age was 70 years. At an average of 33 months postinjury, average flexion was 124°, and extension was -27°, with full forearm rotation. No patients required pain medications at the latest follow-up. At 33 months of follow-up, the average Mayo Elbow Performance Score was 92/100 (100 optimal), Oxford Elbow Score was 43/48 (48 optimal), and Quick Disabilities of the Arm, Shoulder, and Hand Score was 10/100 (0 optimal). All patients were satisfied with the nonsurgical treatment that they received. CONCLUSIONS: Nonoperative treatment for comminuted intra-articular distal humerus fractures results in acceptable functional outcome in elderly patients and should be considered when the fracture is not amenable to internal fixation and in lower-demand patients with higher surgical risk.

Radiographic alignment of unstable distal radius fractures fixed with 1 or 2 rows of screws in volar locking plates.

PURPOSE: We tested the null hypothesis that there is no difference in the change in volar tilt of the articular surface of the distal radius on lateral radiographs obtained before suture removal and 3 months or more after surgical fracture fixation when 1 or 2 rows of screws are used in the distal part of a volar locked plate. METHODS: We retrospectively identified 364 consecutive patients with a distal radius fracture treated by 2 surgeons with open reduction and volar locked plate fixation between 2007 and 2011 at our institution. A manually case-matched design with one-to-one matching of 2 different strategies for screws in the distal part of the plate (1 row versus 2 rows) on the basis of sex, AO type, presence of dorsal comminution, ulna fracture, mechanism of injury, and age (± 8 y) resulted in a group of 34 pairs, 68 total fractures. Radiographic alignment was measured before suture removal and 3 months or more after surgery. RESULTS: The change in volar tilt of the articular surface was -1.2° in the 1-row group and -0.9° in the 2-row group, which was not significantly different. The secondary displacement of radial inclination and ulnar variance were likewise small and not statistically significant. CONCLUSIONS: We found no advantage of 2 rows of distal screws over a single row of screws with respect to maintenance of achieved restoration of volar angulation after volar locked plate fixation of AO type A and C fractures of the distal radius.
