Magnetic Resonance Imaging (MRI) Not Inferior to the Gold Standard of Diagnostic Arthroscopy for Identification of Wrist Ligamentous Pathology.

Accurate diagnoses of wrist ligamentous injuries are critical to guiding the proper treatment pathway for patients with these pathologies. While advancements in imaging continue and magnetic resonance imaging (MRI) is valuable, diagnostic arthroscopy remains superior, particularly if involvement of the non-central triangular fibrocartilage complex (TFCC), scapholunate interosseous ligament (SLIL), or lunotriquetral interosseous ligament (LTIL) is suspected based on history and physical exam, and even in the face of negative MRI findings.

Experimenting With the New Frontier: Artificial Intelligence-Powered Chat Bots in Hand Surgery.

Background: Increased utilization of artificial intelligence (AI)-driven search and large language models by the lay and medical community requires us to evaluate the accuracy of AI responses to common hand surgery questions. We hypothesized that the answers to most hand surgery questions posed to an AI large language model would be correct. Methods: Using the topics covered in Green's Operative Hand Surgery 8th Edition as a guide, 56 hand surgery questions were compiled and posed to ChatGPT (OpenAI, San Francisco, CA). Two attending hand surgeons then independently reviewed ChatGPT's answers for response accuracy, completeness, and usefulness. A Cohen's kappa analysis was performed to assess interrater agreement. Results: An average of 45 of the 56 questions posed to ChatGPT were deemed correct (80%), 39 responses were deemed useful (70%), and 32 responses were deemed complete (57%) by the reviewers. Kappa analysis demonstrated "fair to moderate" agreement between the two raters. Reviewers disagreed on 11 questions regarding correctness, 16 questions regarding usefulness, and 19 questions regarding completeness. Conclusions: Large language models have the potential to both positively and negatively impact patient perceptions and guide referral patterns based on the accuracy, completeness, and usefulness of their responses. While most responses fit these criteria, more precise responses are needed to ensure patient safety and avoid misinformation. Individual hand surgeons and surgical societies must understand these technologies and interface with the companies developing them to provide our patients with the best possible care.

Physical exercise to promote regeneration after peripheral nerve injury in animal models: A systematic review.

Peripheral nerve injuries are common injuries that often have a drastic effect on patient's activities of daily living and physical function. While techniques for the surgical repair of these injuries have improved over time, rehabilitation methods following these repairs have been non-standardized and under researched. Electronic searches were conducted in Ovid/Medline and SCOPUS to identify articles that discuss rehabilitation and exercise following peripheral nerve injury in animal models and its effects on peripheral nerve regeneration and recovery of function. Thirty-eight articles met inclusion criteria; all were prospective studies in animal models. This systematic review suggests that exercise is a useful tool in returning autonomy to the individual and has beneficial effects in the recovery from peripheral nerve injury. It is beneficial to use rehabilitation exercises following the repair of peripheral nerve injuries to promote regeneration, and timing of that exercise may be just as important as the exercise prescribed. However, further studies with standardized models and outcome measures need to be conducted before translation to clinical trials.

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.

Challenges for Women in Hand Surgery: Our Perspective.

Over recent decades, the prevalence of women in surgical subspecialties has increased. There has been a significant rise in the percentage of women entering integrated plastic surgery programs and an increase, albeit smaller, in women entering orthopedic surgery training programs. Although female membership in the American Society for Surgery of the Hand has steadily increased, women remain in the vast minority within this professional society and many others within the field of hand surgery. In addition to underrepresentation in positions of leadership, women face challenges such as imposter syndrome, bullying, unfavorable work structure for work-family balance, macro and micro-aggressions, and lack of mentors at a higher rate than their male colleagues. As awareness rises of the additional challenges that women in hand surgery face, we must directly address them to improve equity within our subspecialty.

Dry Wrist Arthroscopy: Technique and Rationale.

Wrist arthroscopy has been established as a useful, minimally invasive tool for diagnosing and treating many different wrist conditions. The standard portals are located on the dorsum of the hand and wrist and are named for their relation to the extensor compartments. They include the radiocarpal and midcarpal portals. The radiocarpal portals are 3-4, 4-5, 6R, 6U, and 1-2. The midcarpal portals are STT (scaphotrapeziotrapezoidal), MCR (midcarpal radial), and MCU (midcarpal ulnar). Traditionally, wrist arthroscopy is performed with constant inflow of saline solution for joint insufflation and visualization. Dry wrist arthroscopy (DWA) is a technique that allows for arthroscopic exploration and instrumentation without infusing any fluid into the joints. Some advantages of DWA include lack of fluid extravasation, less obstruction by floating synovial villi, decreased risk of compartment syndrome, and the ability to perform concomitant open procedures more easily than with a wet technique. Additionally, the risk of fluid displacing carefully laid bone graft is much less without constant flow. DWA can be used in the assessment and management of triangular fibrocartilage complex (TFCC) and scapholunate interosseous ligament tears and other ligamentous injuries. DWA can also be used in fracture fixation to assist with reduction and restoration of articular surfaces. Moreover, it is used in more chronic settings to diagnose scaphoid nonunions. DWA does have its disadvantages such as generation of heat through the use of burrs and shavers and clogging of these instruments during debridement of tissue. DWA is a technique that can be used to manage multiple orthopaedic conditions including soft-tissue and osseous injuries. With a minimal learning curve for surgeons who already perform wrist arthroscopy, DWA can be a useful addition to their practice.

Primary Repair of Peroneus Longus Myofascial Herniation With Symptomatic Superficial Peroneal Nerve Compression.

Symptomatic myofascial herniations of the extremities occur infrequently; however, they can contribute to significant pain, weakness, and neuropathy with activity. Muscle herniation typically occurs through either a traumatic or congenital focal defect in the deep overlying fascia. Patients may present with an intermittently palpable subcutaneous mass and may have neuropathic symptoms, depending on the degree of nerve involvement. Patients are initially treated with conservative modalities, whereas surgery is reserved for patients who demonstrate persistent functional limitations and neurologic symptoms. Here, we demonstrate a technique for primary repair of a symptomatic lower-leg fascial defect.

Improving Care by Decreasing Wait Times: A Military Health System Quality Improvement Project.

INTRODUCTION: Maximizing patient satisfaction is now a significant focus in many outpatient orthopedic clinics as it has been shown to affect many facets of healthcare. With this quality improvement study, we sought to determine the areas of the longest patient wait time during their clinical encounter and evaluate the effect of an identification card system on those times. We hypothesized that utilizing an identification card system would expedite the time patients spend in the clinic and decrease wait times. METHODS: This quality improvement study was conducted in an orthopedic hand surgery clinic within a military treatment facility. Pre-intervention and intervention data collection consisted of a time sheet that was filled out by surgeons and clinic staff as the patient progressed through their appointment. The intervention consisted of a card system to track the patient throughout their encounter and mark their order in the queue. RESULTS: There were a total of 130 patients in the pre-intervention group and 113 in the intervention group. Compared with the pre-intervention group, the intervention group patients had significantly less time from check-in to being roomed by the clinic staff with a mean of 13 ± 13 vs. 21 ± 19 minutes in the pre-intervention group (P < .001). In the pre-intervention cohort, the average clinic encounter was 66 ± 38 minutes compared to 57 ± 35 minutes in the intervention cohort, which was not statistically significant (P = .112). The time spent with the orthopedic surgeon and occupational therapists increased in the intervention group. CONCLUSION: We provided a simple way to decrease patient wait times and increase time with the healthcare team, utilizing our existing clinic space. Time with the orthopedic surgeon significantly increased because of our intervention, while the overall clinic time trended down.

Innovations in Peripheral Nerve Injury: Current Concepts and Emerging Techniques to Improve Recovery.

Despite the surgical advances in treatment of peripheral nerve injuries, consistent recovery of function is limited suggesting that a multimodal approach is required to optimize nerve regeneration. This approach should include advanced surgical repair techniques, as well as tissue engineering, cellular therapies, and application of local and systemic modulators of neuroregeneration. Further research is needed to advance these therapies from the laboratory to clinical practice, and to further understand how these treatments and techniques can act in concert to optimize functional nerve regeneration.

Editorial Commentary: Artificial Intelligence for the Wrist: Moving to the Forefront of Diagnostic Imaging for Triangular Fibrocartilage Complex Injury.

Accurate diagnosis of the etiology of ulnar-sided wrist pain and injury to the triangular fibrocartilage complex, particularly Palmar 1B tears, can prove to be challenging. Multiple peer-reviewed studies have demonstrated that accurate diagnosis and treatment of tears of the triangular fibrocartilage complex through nonoperative and operative means, including arthroscopy, can result in improved patient outcomes and function. One of the keys to successful treatment, however, is accurate diagnosis. While our current imaging modalities help to provide additional data for the assessment of this pathology, magnetic resonance imaging and computed tomography scans have limitations. Thus, employing the power of artificial intelligence and deep learning to ultrasound assessment of this injury is appealing. Efficient integration of this technology into daily practice has potential to bolster diagnostics not only in large medical centers but also in underserved areas with limited access to magnetic resonance imaging and computed tomography.

Editorial Commentary: Symptomatic Distal Radioulnar Joint Instability After Distal Radius Fracture Fixation: Improved Outcomes With Arthroscopic Management Are Still Possible After a Trial of Nonoperative Treatment.

The literature to guide clinical-decision making for the treatment of symptomatic distal radioulnar joint instability in the setting of distal radius fracture is mixed, with some advocating for surgical treatment at the time of fracture fixation and others reporting acceptable clinical outcomes with conservative management. Given this, it can be challenging to determine which treatment strategy to employ for each individual patient. For injuries that are the result of high-energy trauma or when there is persistent instability lasting 6 months or longer after fracture fixation, surgical intervention may be needed. However, a period of conservative treatment does not appear to result in poorer outcomes.

Overall Safety and Risks Associated with Blood Flow Restriction Therapy: A Literature Review.

INTRODUCTION: Blood flow restriction therapy (BFRT) is used in scenarios ranging from muscle building in athletic performance to decreasing recovery time in postoperative orthopedic rehabilitation. The efficacy of BFRT for treating diseases has been increasingly researched; however, there has been less literature focused on establishing the safety of this therapy. MATERIALS AND METHODS: An extensive literature review pertaining to BFRT and any deleterious events related to its usage was completed by searching multiple databases, including PubMed, EMBASE, and Cochrane Library using the terms "blood flow restriction therapy" or "KAATSU." RESULTS: Ten case reports, five case series, two national surveys, two questionnaires, six randomized controlled studies, and one systematic review were included. A total of 1,672 individuals reported an adverse event following BFRT use out of 25,813 individuals. Commonly reported adverse events were numbness, dizziness, subcutaneous hemorrhage, and rhabdomyolysis. There were unique adverse effects of this therapy reported in individuals with comorbid conditions, such as hypertension and thoracic outlet syndrome, which included isolated cases of central retinal vein occlusion and Paget-Schroeder syndrome. CONCLUSION: Blood flow restriction provides tremendous opportunity with a potential for accelerated exercise rehabilitation and injury prevention. This modality could be used in the military setting to help injured active duty personnel expeditiously return to deployable status. Further prospective randomized controlled trials are warranted to further support BFRT safety; however, from this literature review, it can be concluded that BFRT can be utilized safely in the proper patient population when administered by qualified professionals who have undergone the appropriate training.

Septic Arthritis of the Proximal Interphalangeal Joint After Rattlesnake Bite.

Snake bites are an uncommon injury requiring intervention by hand surgeons. While counteracting the effects of snake venom is the initial and urgent concern following a bite, infection caused by retention of a foreign body can present in a delayed fashion and may lead to increased morbidity. Standard radiographs of the injury should be carefully examined for foreign bodies, noting that retained snake teeth are somewhat radiolucent due to less mineralization as compared to bone and can be difficult to visualize. In our subject, a retained rattlesnake fang was found in association with a septic interphalangeal joint despite appropriate radiographic evaluation and thorough surgical irrigation and debridement upon initial presentation. This case report highlights a potential complication of snake bites, the importance of aggressive management, and the importance of increased suspicion for retained foreign bodies. Augmenting plain radiographs with additional imaging modalities, such as ultrasound, dark-field, and phase-contrast imaging, may aid in the diagnosis of retained foreign bodies after snake bites.

Osteophyte-Sparing Treatment of Mucous Cysts: Case Analysis and Surgical Technique.

OBJECTIVE: The purpose of this study was to examine patient outcomes and the risk of recurrence of mucous cysts affecting the distal interphalangeal (DIP) joint in the absence of osteophytectomy using the described flap technique. METHODS: A retrospective review of 143 records of patients who were treated for mucous cysts of the DIP joint by a single surgeon. Inclusion criteria included the absence of an osteophytectomy during treatment using the described dorsally based flap technique and a minimum of 12 months of follow-up. RESULTS: A total of 143 mucous cysts affecting the DIP joint of 131 patients with an average age of 65.3 years were included. The average follow-up was 21.9 months (12 to 139). Postoperative DIP joint extension was less in the surgical digit compared with the same digit of the contralateral hand with a significant change from the preoperative motion (1.5° versus 0.3°; P = 0.05). No significant change in the postoperative flexion of the DIP joint was observed compared with that of the contralateral side (-1.4° versus -0.9°; P = 0.57). Recurrence occurred in 2 patients (1.4%). No infections or wound complications were identified. CONCLUSIONS: Using the described technique without an osteophytectomy seemed to be an effective treatment of mucous cysts originating from the DIP joint.

NSAID Use and Effects on Pediatric Bone Healing: A Review of Current Literature.

This systematic review evaluates and synthesizes the available peer-reviewed evidence regarding the impact of non-steroidal anti-inflammatory drugs (NSAIDs) on fracture healing in skeletally immature patients. Evidence supports the use of NSAIDs in this patient population for adequate pain control without increasing the risk of nonunion, particularly in long bone fractures and pseudoarthrosis after spine fusion. However, further clinical studies are needed to fill remaining gaps in knowledge, specifically with respect to the spectrum of available NSAIDs, dosage, and duration of use, in order to make broad evidence-based recommendations regarding the optimal use of NSAIDs during bone healing in skeletally immature patients.

Effect of NSAID Use on Bone Healing in Pediatric Fractures: A Preliminary, Prospective, Randomized, Blinded Study.

BACKGROUND: This study aimed to investigate if nonsteroidal anti-inflammatory drugs (NSAIDs) used in the acute phase of bone healing in children with fractures result in delayed union or nonunion as compared with patients who do not take NSAIDs for pain control during this same time period. METHODS: In this prospective, randomized, parallel, single-blinded study, skeletally immature patients with long bone fractures were randomized to 1 of 2 groups for their postfracture pain management. The NSAID group was prescribed weight-based ibuprofen, whereas the control group was not allowed any NSAID medication and instead prescribed weight-based acetaminophen. Both groups were allowed to use oxycodone for breakthrough pain. The primary outcome was fracture healing assessed at 2, 6, and 10 weeks. RESULTS: One-hundred-two patients were enrolled between February 6, 2014 and September 23, 2016. Ninety-five patients (with 97 fractures) completed a 6-month follow-up (46 patients with 47 fractures in the control group and 49 patients 50 fractures in the NSAID group). None achieved healing at 1 to 2 weeks. By 6 weeks, 37 of 45 patients (82%) of control group and 46 out of 50 patients (92%) of ibuprofen group had healed fractures (P=0.22). At 10 to 12 week follow-up, 46 (98%) of the control group fractures were healed and 50 (100%) of the ibuprofen group fractures were healed. All were healed by 6 months. Healing was documented at a mean of 40 days in the control group and 31 days in the ibuprofen group (P=0.76). The mean number of days breakthrough oxycodone was used was 2.4 days in the control group and 1.9 days in the NSAID group (P=0.48). CONCLUSION: Ibuprofen is an effective medication for fracture pain in children and its use does not impair clinical or radiographic long bone fracture healing in skeletally immature patients. LEVEL OF EVIDENCE: Level I-therapeutic.

Treatment of a Subacute Locked Thumb Metacarpophalangeal Joint with Sesamoid Entrapment.

INTRODUCTION: Locked thumb metacarpophalangeal (MCP) joints due to entrapped radial sesamoids are rare injuries that commonly require open reduction, especially when the injury is delayed in presentation. CASE PRESENTATION: We present a case of a 24-year-old female with a subacute thumb MCP joint subluxation due to an incarcerated radial sesamoid. She underwent successful closed reduction but had persistent pain and difficulty gripping large objects necessitating eventual open volar plate repair despite therapy. She was able to achieve full motion, with little pain and disability, after undergoing delayed volar plate repair. DISCUSSION: Delayed volar plate repair may be considered for those patients who fail to improve with conservative management and occupational therapy after a successful closed reduction for thumb MCP joint subluxation due to an incarcerated radial sesamoid.

Open Reduction Internal Fixation of a Traumatic Osteochondral Lesion of the Patella With Bioabsorbable Screw Fixation.

Osteochondral injuries of the patella occur often in the setting of traumatic patellar dislocations. Early fixation of the displaced fragment(s) is paramount to maintaining the viability of the articular cartilage and the congruency of the patella. Multiple fixation techniques have been described to ensure stable fixation, including wires, screws, and all-suture techniques with both absorbable and nonabsorbable materials. We performed an open reduction and internal fixation of a large traumatic patellar osteochondral lesion using 3 bioabsorbable compression screws. The technique is straightforward and provides compression across the fragments, affording excellent stability, which allows early range of motion and ambulation.

Patient Factors, Donor Age, and Graft Storage Duration Affect Osteochondral Allograft Outcomes in Knees with or without Comorbidities.

Limited data exists defining preoperative variables that affect outcomes after osteochondral allograft transplantation (OAT) in the knee. In this retrospective study, we examined 75 patients who underwent OAT for large (≥2 cm2) grade IV cartilage defects in the femoral condyle. Patient variables evaluated included the following: smoking, workers compensation, body mass index (BMI), pre-injury activity level, number, and the type of co-morbidities in the operated knee, lesion location and number of grafts placed. OCA donor age and graft storage duration from procurement were also evaluated. Preoperative and postoperative visual analogue scale (VAS) pain scores were the primary outcome measure. Overall, 53 patients (71%) had successful outcomes, with 81% of patients without co-morbidities having successful outcomes. Active patients were significantly (p = 0.023) more likely to have a successful outcome than low activity patients. Patients with BMI <35 were 4 times more likely to have a successful outcome (p = 0.01). There were no significant differences based on donor age. Patients with transplanted grafts stored >28 days were significantly (p = 0.048) and 2.6 times more likely to have an unsuccessful outcome. This study provides new evidence for preoperative patient factors and graft variables that may influence the overall outcome after osteochondral transplantation in the knee.
