Purpose: Saws are a common source of upper extremity injury. There have been several commercial and government-mandated safety mechanisms designed to reduce the number of saw injuries. We aim to assess the trends in the incidence and impact of saw-related upper extremity injuries over the last 2 decades.

Methods: The National Electronic Injury Surveillance System database was queried from January 2003 to December 2022 for upper extremity injuries caused by saws. Summary statistics for primary body part injured and diagnosis were calculated. Linear regression was performed to evaluate trends in the number of injuries over time.

Results: An estimated 1.38 million injuries (weighted) presenting to emergency departments were reported from January 2003 to December 2022. Patients had a mean age of 50.5 ± 18.1. Digits (82.2%) accounted for most injuries, followed by hands (11.9%). The lower arm (3.4%), wrist (1.66%), shoulder (0.3%), elbow (0.2%), and upper arm (0.2%) accounted for fewer injuries. There was a downtrend in number of saw injuries over the study period (R = 0.83, R2 = 0.69, p < .001). Subgroup analysis showed decreases in number of injuries to fingers (R = -0.82, R2 = 0.67, p < .001) and wrists (R = -0.61, R2 = 0.37, p = .004). The most common diagnoses were lacerations (69.7%), fractures (12.6%), and amputations (9.9%).

Conclusions: Upper extremity saw injuries have significantly decreased over the last 20 years. The fingers and hands account for the vast majority of saw injuries, resulting most commonly in lacerations, fractures, and amputations.

Hand osteomyelitis is a complex condition to diagnose and treat, with an opportunity to improve care through organization of existing evidence. The literature was systematically searched for series of hand osteomyelitis between 1990 and 2022 for evidence regarding diagnosis and treatment, to formulate recommendations. Twenty-one series reported at least 5 cases of hand osteomyelitis in adults, with a total of 666 cases. Surgical debridement is central to treatment and oral antibiotics are sufficient for individuals without diabetes, renal or vascular disease, after debridement and resolution of associated sepsis. A 4- to 6-week duration of antibiotic therapy according to organism sensitivities is recommended, or a 2-week course after amputation. Delayed presentation is common and if over 6 months is associated with high amputation rates. Hand osteomyelitis with renal failure is associated with systemic complications. Reconstruction options include antibiotic-eluting spacers, osteosynthesis or arthrodesis, vascularized bone or adipose, regional soft tissue coverage and silicone implant arthroplasty.Level of Evidence: IV.

Background: Outcomes of interposition arthroplasty for treatment of elbow arthritis are highly dependent on elbow stability. The purpose of this study was to determine whether interposition arthroplasty with a novel bidirectional ligament reconstruction technique could adequately restore the static stability of the native elbow.

Methods: Static varus and valgus elbow stability was tested in 7 cadaver elbows with intact ligaments and capsule at 5 flexion angles (0°, 30°, 60°, 90°, and 120°). At each angle, the distance between fixed reference points across the elbow was measured both medially and laterally. The elbows were then destabilized and an interposition arthroplasty with ligament reconstruction was performed. Static elbow stability was reassessed by comparing postoperative deflection measurements with those of the native state. Graft slippage or loosening was visually assessed following testing.

Results: Interposition arthroplasty was performed in 7 cadaver specimens. Following ligament reconstruction, specimens reproduced the flexion angle-dependent static stability of native elbows to both varus and valgus stress. The greatest deflection changes between native elbows and elbows after interposition arthroplasty were 2.7% (P = .13) medially and 2.3% (P = .42) laterally, which were not significant. There was no loosening or slippage of either the interposition graft or the ligament reconstruction grafts.

Conclusions: Cadaveric elbow specimens underwent interposition arthroplasty with a novel technique for bidirectional ligament reconstruction. Static stability was maintained at varying degrees of elbow flexion, comparable to that of the native elbow. Interposition and ligament reconstruction grafts maintained secure fixation following static biomechanical testing.

Background: The effect of cannabis on pain management following open carpal tunnel release (CTR) surgery is unknown. The purpose of this study is to compare outcomes for patients with cannabis-related disorder (CRD) undergoing open CTR to a propensity-matched cohort of patients without CRD (no cannabis-related disorder [NCRD]).

Methods: The TriNetX Research Network was queried to identify patients undergoing primary open CTR between January 2010 and December 2022. Patients with CRD were propensity matched to a NCRD cohort in a 1:1 ratio based on 7 characteristics. Rates of postoperative opioid prescriptions, emergency department (ED) services, and outpatient appointments were reported at 0-2, 2-6, and 6-12 weeks postoperatively.

Results: A total of 925 CRD patients were propensity matched to 925 NCRD patients undergoing open CTR. Within 0-2 weeks postoperatively, CRD patients received significantly greater rates of opioid prescriptions compared to NCRD patients (30.9% and 25.6%, P = .011). No cannabis-related disorder (NCRD) patients presented for outpatient follow-up at significantly higher rates than CRD patients within 6 weeks postoperatively. CRD patients presented to the ED at significantly higher rates between 6 and 12 weeks postoperatively (11.0% vs. 8.0%, respectively, P = .027).

Conclusions: Cannabis-related disorder (CRD) is associated with lower rates of outpatient follow-up but higher rates of postoperative opioid prescriptions and ED presentations following open CTR compared to a propensity-matched cohort of NCRD patients.

Level of evidence: Cohort Study; Level III.

Background: The impact of social determinants of health on patients' access to medical care and health outcomes is increasingly recognized. Telemedicine's rapid and widespread adoption altered the delivery of care. This study describes the characteristics of patients undergoing telemedicine visits with hand surgeons, without COVID-19 pandemic-related restrictions.

Methods: All telemedicine encounters for 4 hand surgeons at a single institution between September 2022 and September 2023 were retrospectively reviewed. Patient demographics were recorded as well as the encounter type. The distance of the patients' residential address and the area deprivation index (ADI) were recorded.

Results: Sixty patient encounters were recorded. Forty-seven percent were male and 53% were female, 5 (8.3%) were new patients, 44 (73.3%) were established patients, and 11 (18.3%) were postoperative. The mean age was 43, and the mean and median distances from the clinic were 72 and 18 miles, respectively. Forty-three patients (72%) were from high ADI residences. Upon comparison of low ADI (0-50th percentile) and high ADI (50th-100th percentile) patients, no statistically significant differences in age, sex, distance from clinic, or encounter type were found.

Conclusions: Telemedicine in hand surgery at this single institution is most frequently used for follow-up encounter types in patients living in high ADI communities, far from clinic sites. Low or high ADI did not correlate with seasonal changes in the use of telemedicine, encounter type, or patient demographics. Telemedicine may improve patient access to hand surgery follow-up care. This may particularly benefit patients facing geographic and economic challenges to healthcare access.

Level of evidence: Prognostic Level IV.

Background: The role of surgery in normal or very mild median neuropathy can be questioned given that surgery in the absence of pathophysiology may offer only nonspecific effects that can be achieved without surgery, which raises ethical concerns. It's also important to avoid misdiagnosis: given that mild median neuropathy is prevalent and generally well-accommodated, notable symptoms from mild median neuropathy can signal unhelpful thoughts and feelings of distress that are a more pressing health priority.

Methods: We identified 38 studies that categorized electrodiagnostic (EDX) measured median neuropathy severity among people being evaluated for carpal tunnel syndrome. We converted the different EDX grades used into one general grading classification. The Kruskal-Wallis test was used to compare the ratio of moderate/severe to mild/normal EDX findings between tests ordered by a surgeon or a nonoperative clinician.

Results: The median (interquartile range) ratio of moderate/severe to mild/normal EDX findings of median neuropathy at the carpal tunnel was 1.2 (0.91 to 1.8) among tests ordered by nonoperative clinicians and 3.3 (1.5 to 5.3) among tests ordered by surgeons (P = .0023). Only 4.1% of the patients who had EDX testing ordered by a surgeon had no measurable neuropathy. There were zero patients with normal EDX findings in 10 of the 17 (59%) studies in surgeon practices and in 10 of the 21 (48%) in the practices of nonoperative clinicians.

Conclusions: The observation that in case series documenting EDX severities of median neuropathy, surgeons are mostly treating and operating on moderate to severe pathophysiology, emphasizes that while mild median neuropathy is highly prevalent it is uncommonly considered for surgery.

Level of evidence: Level II, Prognostic study.

Background: Uncertainty exists concerning the optimal utilization and effectiveness of pectoralis minor tenotomy (PMT) in neurogenic thoracic outlet syndrome (NTOS).

Methods: Between January 2020 and July 2023, 355 patients with NTOS underwent primary surgical treatment. Prospectively collected data were analyzed retrospectively.

Results: Overall mean patient age was 35.9 ± 1.9 years, 76% were female, and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score at presentation was 60.3 ± 3.2, reflecting substantial disability. Surgical treatment was based on localized tenderness/symptoms to palpation, with 322 (91%) undergoing combined supraclavicular decompression and PMT (SCD + PMT) and 33 (9%) selected for isolated PMT when findings were solely confined to the subcoracoid space. Mean operative time (29 ± 5 vs 164 ± 9 min, P < .01) and hospital stay (0.3 ± 0.1 vs 4.0 ± 0.2 days, P < .01) were both lower after isolated PMT, with no significant differences in postoperative complications or rehospitalization. During follow-up of 26.7 ± 1.5 months, QuickDASH scores declined by 41.2% ± 2.3% (P < .0001) and patient-rated outcomes were excellent in 34%, good in 41%, fair in 22%, and poor in 4%. Fewer patients had poor-rated outcomes after SCD + PMT (2%) than after isolated PMT (19%) (P < .01). Recurrent symptoms requiring supraclavicular reoperation occurred in 16 patients after SCD + PMT (5%) and in 5 patients after isolated PMT (15%) (P < .05).

Conclusions: Pectoralis minor tenotomy (PMT) has an important role in surgical treatment of NTOS, mainly as an adjunct in combination with SCD. While highly selected patients can do well after isolated PMT as a short outpatient procedure with rapid recovery, there is a greater potential for poor outcomes and supraclavicular reoperation than after SCD + PMT.

Background: The 2 primary surgical approaches for proximal interphalangeal joint (PIPJ) arthroplasty, dorsal or volar, have been extensively described in the literature. However, the ongoing debate regarding which approach offers superior results or is associated with fewer complications persists. This systematic review aims to compare the outcomes of PIPJ arthroplasty between the dorsal and volar approaches.

Methods: A comprehensive search of multiple databases was conducted, and studies meeting predetermined criteria were included. Data extraction, assessment of bias risk, and statistical analysis were performed to compare treatment modalities. Outcome measures included range of motion (ROM), patient-reported outcome measures (PROMs), revisions, and reported complications.

Results: Among 368 screened articles, 5 studies involving 302 patients (310 implants) were eligible for final review. No significant differences were observed between the 2 approaches regarding postoperative ROM (mean difference [MD] 2.24; 95% confidence interval [CI] -3.83, 8.32; P = .47) and PROMs (standardized mean difference [SMD] 0.18; 95% CI -0.12, 0.48; P = .25). Complication rates, including revision/fusion, persistent pain, stiffness, infection, and dislocation, did not significantly differ between the approaches. Notably, dorsal approach was associated with higher risk of swan-neck deformity (9 out of 82 implants), while no such cases were reported in the volar approach (0 out of 101 implants).

Conclusion: Despite limitations and heterogeneity in the literature, both dorsal and volar approaches for PIPJ arthroplasty appear to yield equivalent outcomes for patients.

Level of evidence: II, therapeutic.

The recurrent motor branch (RMB) of the median nerve has commonly thought to originate proximal to the terminal digital branches, although its anatomical course and number may vary. We report a rare variation of the RMB that arose from the second common palmar digital nerve. The median nerve bifurcated into the first and second common palmar digital nerves distal to the transverse carpal ligament, with the RMB dividing from the second common palmar digital nerve and traveling retrograde to enter the abductor pollicis brevis muscle. This high origin variation may be at increased risk of injury during procedures of the hand.

Background: Cannabinoids are a diverse group of compounds under investigation for various medical purposes, including analgesia. Given the evolving landscape of cannabinoid use, we aimed to analyze their prevalence and effect in pain management among urban orthopedic hand patients.

Methods: An electronic survey was administered to 122 new patients presenting to the orthopedic hand clinic of a major urban academic hospital. Demographic data, numerical rating scale pain scores, cannabinoid usage, and other concomitant pain regimens were recorded.

Results: Approximately half of the new patients were dissatisfied with current pain management for their hand pathology. Prescription (Rx) and over-the-counter (OTC) pain medications were used by 58% (71/122) of patients, while cannabinoids were used by 15% (18/122) of patients. Compared with pre-usage pain scores, both cannabinoids and Rx/OTC medications induced significant reductions in pain associated with patients' hand pathologies (Cannabinoid: Δ4.4, P = .002; Rx/OTC: Δ3.0, P < .001). Cannabinoids induced a larger analgesic effect, but this difference was not statistically or clinically significant (P = .06). Subjectively, cannabinoid users either preferred their cannabinoid over Rx/OTC medications or liked both equally. Opioid use was higher among cannabinoid users (22.2% vs 12.5%), although this was not statistically significant (P = .28).

Conclusion: Approximately 15% of new urban hand patients use cannabinoids for pain control, and these compounds have similar analgesic efficacy in hand pathologies as Rx/OTC medications. Cannabinoids are equally liked or preferred relative to traditional medications in this cohort, and they may play an important role in pain management for hand patients.
