Background: Traumatic digit amputation is a common injury with life-altering consequences for thousands of patients each year. In this study, we aim to update and expand the reported outcomes of return-to-work (RTW) and functional recovery in patients treated with digit replant after traumatic amputation.

Methods: A PRISMA-guided systematic review was performed to identify all published articles related to digit replantation following amputation. We queried the following 4 databases: Scopus, Embase, Web of Science, and PubMed-MEDLINE. A total of 31 studies were included in the analysis of return-to-work data.

Results: Of the 31 included studies, 26 studies reported that 1976 digits were successfully replanted, while 27 studies reported that 300 replants failed (86.8% success rate). Among 1087 patients in these studies, 82.9% who underwent replantation returned to work. The mean RTW time in 16 studies was 4.7 months (weighted average). Return-to-work time ranged from 0 to 26 months in 12 studies. Of 352 patients who returned to work in 17 studies, 90.9% resumed their previous occupation, while 29 (8.2%) changed occupations. The RTW for finger-only replantations was significantly lower compared to thumb-only, distal digit-only, and any digit replantations (66.0% vs 82.8%; 66.0% vs 87.6%; 66.0% vs 82.9%).

Conclusion: Despite a declining prevalence of digit replantation surgery in recent years, this study illustrates that replantation provides beneficial outcomes for patients with a high return-to-work rate.

Background: Generative artificial intelligence (AI) models have emerged as capable of producing human-like responses and have showcased their potential in general medical specialties. This study explores the performance of AI systems on the American Society for Surgery of the Hand (ASSH) Self-Assessment Exams (SAE).

Methods: ChatGPT 4.0 and Bing AI were evaluated on a set of multiple-choice questions drawn from the ASSH SAE online question bank spanning 5 years (2019-2023). Each system was evaluated with 999 questions. Images and video links were inserted into question prompts to allow for complete AI interpretation. The performance of both systems was standardized using the May 2023 version of ChatGPT 4.0 and Microsoft Bing AI, both of which had web browsing and image capabilities.

Results: ChatGPT 4.0 scored an average of 66.5% on the ASSH questions. Bing AI scored higher, with an average of 75.3%. Bing AI outperformed ChatGPT 4.0 by an average of 8.8%. As a benchmark, a minimum passing score of 50% was required for continuing medical education credit. Both ChatGPT 4.0 and Bing AI had poorer performance on video-type and image-type questions on analysis of variance testing. Responses from both models contained elements from sources such as PubMed, Journal of Hand Surgery, and American Academy of Orthopedic Surgeons.

Conclusions: ChatGPT 4.0 with browsing and Bing AI can both be anticipated to achieve passing scores on the ASSH SAE. Generative AI, with its ability to provide logical responses and literature citations, presents a convincing argument for use as an interactive learning aid and educational tool.

Background: The concordance between patient and physician goals has been associated with improved outcomes in many chronic diseases. The purpose of this study was to evaluate the association between goal concordant care, patient satisfaction, and patient experience and to analyze factors associated with goal concordant care in hand and upper extremity surgery.

Methods: New patients who were 18 years or older were invited to participate. Goal concordant care was defined as the patient's previsit treatment goal matching the primary treatment received. The χ² tests were used to evaluate the association between goal concordant care and patient satisfaction and patient experience. We conducted univariable logistic regression to evaluate variables for their association with concordance and multivariable logistic regression for variables that were significantly associated in the initial analyses to evaluate their aggregate influence on concordance.

Results: In total, 169 patients enrolled. The rate of goal concordant care was 62%; concordance was not associated with patient satisfaction or experience. Age, sex, English proficiency, health literacy, education level, employment and relationship status, pain self-efficacy, symptom duration, functional disability, and patient-centered decision-making were not associated with concordant care. Patients with annual income less than $50,000 had significantly higher odds of goal discordant care.

Conclusion: Patients with lower income had more than 3 times the odds of receiving discordant care. However, discordant care was not associated with patient satisfaction or experience. Further studies on other pertinent outcomes are needed in orthopedic surgery (eg, treatment adherence). Known care disparities based on socioeconomic status may be mediated through care discordance and should be investigated.

Pediatric phalangeal Salter-Harris (SH)-type fracture dislocations are rare injuries that often require open reduction and stabilization. We present a case of a 14-year-old male who sustained an iatrogenic irreducible SH II dorsal fracture dislocation of the small-finger proximal interphalangeal joint (PIPJ) after an attempted closed reduction of a small-finger PIPJ dislocation by a community emergency medicine physician. Following the reduction attempt, the epiphysis was noted on radiographs to be rotated approximately 90° with persistent dorsal dislocation and an associated SH II fracture of the base of the middle phalanx. The patient was sent to our trauma center for further evaluation by our on-call hand surgeon and required open reduction and pinning of the fracture dislocation. To our knowledge, this pattern of iatrogenic PIPJ fracture dislocation has not been previously described in the literature. We outline the case presentation, treatment method, and learning points for both the on-call hand surgeon as well as the community emergency medicine physicians in this report.

Background: Radiocarpal dislocation (RCD) and radiocarpal fracture dislocation (RCFD) are rare but severe injury patterns with multiple types of fixation techniques described. The purpose of this study was to determine the outcomes of RCD and RCDF treated at our institution.

Methods: Patients were identified using our institution's electronic medical records between 2013 and 2022. Seventeen patients met criteria who suffered either RCD or RCFD. Patient charts were reviewed retrospectively with a focus on demographics, mechanism of injury, smoking status, open injury, direction of dislocation, Moneim and Dumontier classification, procedures, complications, final range of motion and subsequent surgeries.

Results: Seventeen patients met criteria with an average age of 38.5 years. Thirteen patients sustained dorsal dislocations while 4 sustained volar dislocations. Four were Dumontier type I and 13 were type II. Twelve were Moneim type I and 5 were type II. Fourteen of the 17 patients had at least 6-month follow-up. The average flexion and extension at time of last follow-up was 33.6° and 39.5°, respectively. Average pronation and supination was 80.6° and 63.1°, respectively. Fourteen patients underwent subsequent surgeries, mainly hardware removal, and 5 had complications resulting in unplanned return to the operating room. There was no significant difference in post operative range of motion, complications, or subsequent surgeries based on Moneim or Dumontier classification (P > 0.11).

Conclusions: Radiocarpal dislocation and RCFD are challenging and rare injuries with multiple patterns and variance. With proper fixation and recognition of associated injuries, patients with these injuries can expect to return to work and achieve functional range of motion.

This systematic review with meta-analysis compared the diagnostic accuracy of neuromuscular ultrasound (NMUS) and electrodiagnostic studies (EDX) as confirmatory tests for carpal tunnel syndrome (CTS) diagnosis. We used bivariate random-effects models to estimate pooled sensitivity and specificity and generate hierarchical summary receiver-operating characteristic curves to assess diagnostic test accuracy. Nine paired accuracy studies were included, representing 1751 hands (743 clinically diagnosed CTS; 1008 without CTS) that underwent NMUS and EDX. Compared to the clinical diagnosis reference standard, the pooled sensitivity was 86.4% for NMUS and 91.6% for EDX. Pooled specificity was 79.3% for NMUS and 81.9% for EDX. The positive likelihood ratios were 4.2 and 5.1 for NMUS and EDX, respectively, and the negative likelihood ratios were 0.17 and 0.10, respectively. The diagnostic odds ratio was 24 for NMUS and 49 for EDX. No statistically significant differences were identified between NMUS and EDX for sensitivity, specificity, or overall diagnostic accuracy. Overall, the diagnostic accuracy of NMUS is similar to that of EDX for CTS diagnosis, with high sensitivity and moderate specificity for each. The choice between these confirmatory diagnostic tests should incorporate shared decision-making between patients and providers that weighs diagnostic accuracy as well as factors such as patient preferences, test availability, cost, and tolerability.

Background: The aim of this study was to describe the presence of pain sensitization (PS) and its association with baseline factors after cast removal in patients older than 60 years with distal radius fracture (DRF) treated conservatively.

Methods: This cross-sectional study included 220 patients older than 60 years with extra-articular DRF who completed the Pain Sensitivity Questionnaire (PSQ). Patients with PSQ score > 7 points were considered positive for PS. In addition, sociodemographic, anthropometrics, clinical, radiological, lifestyle behaviors, pain-related psychological factors, and functional outcomes were analyzed as baseline predictors, all measured were performed 2 weeks after cast removal.

Results: A total of 159 patients (72.3%) showed PS. The results showed an association between higher values of PSQ-total with the affected dominant hand (β = 1.1; P = 0.04), high energy of injury (β = 3.5; P < .001), extra-articular comminuted metaphyseal DRFs (β = 1.8; P < .001), lower values of Rapid Assessment of Physical Activity questionnaire (β = 3.1; P < .001), higher values of Pittsburgh Sleep Quality Index (β = 2.5; P < .001), higher values of Tampa Scale of Kinesiophobia (β = 1.9; P < .001), higher values of Pain Catastrophizing Scale (β = 1.8; P < .001), higher values of Disabilities of the Arm, Shoulder and Hand questionnaire (β = 1.6; P < .001), lower values of grip strength (β = 1.4; P < .001) and higher values of Visual analog scale (β = 4.2; P < .001).

Conclusions: A high percentage of patients older than 60 years with extra-articular DRFs present PS at 2 weeks after cast removal. Our results may help physicians and physiotherapists identify risk and/or prognostic baseline factors for the occurrence of PS after DRF, and the need for a therapeutic approach that incorporates the clinical management of this condition in these patients.

Background: Surgical management of failed metacarpophalangeal (MCP) arthroplasties includes revision arthroplasty and arthrodesis. The purpose of this study was to review the indications and outcomes of arthrodesis as a salvage procedure for failed MCP arthroplasties.

Methods: This was a retrospective cohort study of all patients undergoing salvage MCP arthrodesis at a single institution from 1990 to 2020. Patient charts were reviewed for patient demographics, indication for salvage, surgical technique, revision rate, and time to radiographic union. Patient-reported outcomes, including the Michigan Hand Outcomes Questionnaire and an MCP-specific questionnaire detailing pain, functional, appearance, and patient satisfaction, were also collected.

Results: Eleven digits in 9 patients (6 women, 3 men, median age of 66) with median 36-month follow-up were included. The majority (91%) of patients also had concomitant soft tissue deformities, including joint contractures, extension lag, and collateral ligament insufficiency. The overall revision rate following arthrodesis was 45% with 3 digits requiring one revision each, and 2 digits undergoing 3 revisions. The overall union rate was 91% with median time to union of 4 months from most recent arthrodesis. Patient-reported outcomes obtained from 4 patients demonstrated improvements in pain and function.

Conclusion: Despite a high revision rate of 45%, salvage MCP arthrodesis following arthroplasty has a high eventual union rate of 91% and is associated with improved pain and function based on 4 patients' experiences. Arthrodesis as a salvage procedure for failed MCP arthroplasties should be considered in patients with persistent joint instability and functionally limiting soft tissue deformities.

Simultaneous dislocation of the distal and proximal interphalangeal joints is an uncommon injury. Treating chronic cases proves challenging due to severe contractures affecting both joints and surrounding soft tissues. Here, we report an unusual chronic contracture case in a 46-year-old man who suffered a dorsal dislocation of the distal and proximal interphalangeal joints of the little finger. The patient underwent primary joint distraction followed by open reduction, leading to stable radiographic restoration and a functional range of motion in the affected finger 6 months postoperatively. Joint distraction was a reliable approach for the treatment of chronic joint dislocation with severe soft tissue contracture, especially for multiple joint contractures. In addition, the Ilizarov mini-fixator device was effective in enabling individualized traction on both the distal and proximal interphalangeal joints.

The palm is of great importance for maintaining a functioning hand. The reconstructive demands of thickness, texture, color matching, pliability, and sensation for palmar defects represent a unique challenge for plastic surgeons. This study introduced a novel versatile design for the ulnar palmar artery perforator flap (UPAPF) to cover large palmar soft-tissue defects of the hand. The fifth metacarpophalangeal joint was identified as a landmark where the perforator was nearly 1 to 1.5 cm proximal. A template of the defect was outlined after adequate debridement. Meticulous dissection was executed under loupe magnification to trace the perforator until an adequate length of the pedicle was obtained for rotation. The harvested type B fasciocutaneous flap was rotated nearly 90° to be insetting on the palmar defect. Two patients were presented with a soft-tissue defect of the palm measuring 4.8 × 5.5 cm² and 3.8 × 5 cm², respectively. The flap was harvested and positioned at the defects. The flaps survived in the 2 cases with minimal donor site complications. The patients acquired protective sensations within the flap at the end of the follow-up period. The UPAPF provides a stable coverage for palmar soft-tissue defects with satisfactory aesthetic and functional results. It is a convenient addition to the armamentarium for reconstructing palmar soft-tissue defects of the hand.
