Abstract Background Patients often turn to online reviews as a source of information to inform their decisions regarding care. Existing literature has analyzed factors associated with positive online patient ratings among hand and wrist surgeons. However, there is limited in-depth analysis of factors associated with low patient satisfaction for hand and wrist surgeons. The focus of this study is to examine and characterize extremely negative reviews of hand and wrist surgeons on Yelp.com. Methods A search was performed using the keywords “hand surgery” on Yelp.com for eight major metropolitan areas including Washington DC, Dallas, New York, Phoenix, Los Angeles, San Francisco, Boston, and Seattle. Only single-star reviews (out of a possible 5 stars) of hand and wrist surgeons were included. The complaints in the 1-star reviews were then categorized into clinical and nonclinical categories. Result A total of 233 single-star reviews were included for analysis, which resulted in 468 total complaints. Of these complaints, 81 (18.8%) were clinically related and 351 (81.3%) were nonclinical in nature. The most common clinical complaints were for complication (24 complaints, 6%), misdiagnosis (16 complaints, 4%), unclear treatment plan (16 complaints, 4%), and uncontrolled pain (15 complaints, 3%). The most common nonclinical complaints were for physician bedside manner (93 complaints, 22%), financially related (80 complaints, 19%), unprofessional nonclinical staff (61 complaints, 14%), and wait time (46 complaints, 11%). The difference in the number of complaints for surgical and nonsurgical patients was statistically significant (p < 0.05) for complication and uncontrolled pain. Clinical Relevance Patient satisfaction is dependent on a multitude of clinical and nonclinical factors. An awareness of online physician ratings is essential for hand and wrist surgeons to maintain and improve patient care and patient satisfaction. We believe the results of our study could be used to further improve the quality of care provided by hand and wrist surgeons.

AbstractPurposeTo determine whether a 24 MHz transducer significantly improves sensitivity, specificity and accuracy in evaluating flexor tendon repair integrity compared with an 18 MHz transducer.MethodsOne hundred and twelve cadaveric digits were randomised to an intact repair or simulated ‘failed’ repair, and to a two‐ or eight‐strand repair of a flexor digitorum profundus laceration. A blinded sonologist evaluated specimens in static mode using 18 and 24 MHz transducers. Gaps were remeasured after scanning, and final gap width recorded. McNemar's exact test calculated differences between sensitivity, specificity and accuracy, and chi‐squared test to compare sensitivity, specificity and accuracy between number of strands (2 vs. 8) and repair gap (≥4 mm).ResultsThe 24 MHz transducer had higher sensitivity (81 vs. 59%), lower specificity (67 vs. 70%) and higher overall accuracy (74 vs. 64%), than the 18 MHz transducer. The difference for sensitivity was significant (P = 0.011), but not differences for specificity and overall accuracy (P > 0.05). Pearson's correlation (r = 0.61) demonstrated a moderate‐to‐strong positive correlation between measured and true gap sizes. Increased number of suture strands (2 vs. 8) did not impair sensitivity, specificity nor accuracy.DiscussionUltrasound may tend to overestimate gap width, and a slight risk that some intact repairs, or those with small, clinically insignificant gaps may undergo surgical exploration that may not be indicated.ConclusionsA 24 MHz transducer is a more sensitive and accurate transducer for assessing flexor tendon repair integrity and measuring small gaps.

Background: The authors examined whether ultrasound sensitivity, specificity, and accuracy in identifying intact repairs or flexor tendon gapping after zone 2 repair are affected by the number of suture strands crossing the repair or gap or imaging modality (static versus dynamic). Methods: A total of 144 fresh-frozen cadaveric digits (thumbs excluded) were randomized to either an intact repair (0-mm gap) or simulated failed repair (4-mm gap), as well as to either a two- or eight-strand locked-cruciate repair of a zone 2 flexor digitorum profundus tendon laceration using 4-0 Fiberwire. Examinations were performed by a blinded musculoskeletal ultrasonographer in static and dynamic modes using an 18-MHz transducer. Gaps were remeasured after scanning, and the final gap width recorded. McNemar exact test was used to determine whether there were differences in sensitivity, specificity, and accuracy affected by modality (static versus dynamic), and chi-square test was used to compare sensitivity, specificity, and accuracy between number of strands (two versus eight) crossing the intact repair or repair gap (≥4 mm). Results: Sensitivity, specificity, and accuracy improved with increased number of suture strands crossing the repair or gap (eight versus two), irrespective of modality (static versus dynamic), and dynamic compared with static scanning modes, irrespective of number of suture strands crossing the repair or gap site. Conclusions: The most sensitive and accurate means of assessing flexor tendon repair integrity and gapping were seen using the dynamic scanning mode. Increased number of suture strands did not negatively affect sensitivity, specificity, or accuracy, regardless of scanning mode (dynamic or static).

Background: Reliable methods for measuring range of motion is important for hand therapists. Currently, there is no gold standard for the measurement of thumb metacarpophalangeal joint (MCPJ) hyperextension. We hypothesised that visual and goniometric measurements of thumb MCPJ hyperextension vary greater than 10° from radiographic measurements, and between observers. Methods: Twenty-six fresh-frozen hands were measured by a senior orthopaedic resident and fellowship trained hand surgeon. Passive thumb MCPJ hyperextension was measured by visual estimation, goniometry and axis measurement on a lateral thumb radiograph. Raters were blinded to each other’s and their own prior measurements. Descriptive statistics were recorded for measurement type and inter-observer agreement using a two-way intra-class correlation coefficient (ICC). Intra-observer agreement was calculated using concordance correlation coefficient (CCC). Bland–Altman plots identified trends, systemic differences or potential outliers. Results: Mean measurements for both raters were similar for visual estimation and radiographic measurements. Mean goniometric measurements were twice as high for Rater B, and closer to radiographic measurements. For both raters, mean radiographic measurements were 10° greater than the other two methods. For inter-rater agreement, measurements were within 10° most frequently with radiographic measurement, then visual estimates, and least by goniometer measurements. Rater B had better agreement comparing visual and goniometric to radiographic measurements. Conclusions: Radiographic measurement has the best inter-observer agreement and precision for evaluating passive thumb MCPJ hyperextension, especially considering adjunct corrective procedures when performing a soft-tissue basal joint arthroplasty. Rater experience improves precision, but there is still poor agreement between visual estimates and goniometer measurements compared to radiographic measurements, as the former two underestimate hyperextension by 10°. Development of a standard method of clinical measurement is needed to improve reliability.

Background: Carpal tunnel release (CTR) surgery is the most common surgery billed to Medicare by hand surgeons. As such, the purpose of this study was to evaluate trends for CTR surgeries billed to Medicare from 2000 to 2020. Methods: The publicly available Medicare Part B National Summary File from 2000 to 2020 was queried. For both open carpal tunnel release (OCTR) and endoscopic carpal tunnel release (ECTR), the number of procedures and total Medicare reimbursement were extracted. For year 2020, the specialty of the performing surgeon was recorded. Descriptive statistics were reported. Results: A total of 3 429 471 CTR surgeries were performed in the Medicare population from 2000 to 2020. For these procedures, Medicare paid surgeons over $1.23 billion. During this period, there was a 101.8% increase in annual CTR procedures (91 130 in 2000, 183 911 in 2020). Further, annual volume of ECTR increased by 456.2%, and accounted for an increasing percentage of total CTR procedures (9.1% in 2012, 25.2% in 2020). The average adjusted Medicare reimbursement per procedure decreased by 1.5% for OCTR, and decreased by 11.6% for ECTR. In 2020, orthopedic surgeons performed 85.1% of CTR procedures. Conclusions: The volume of CTR surgeries among the Medicare population has increased from 2000 to 2020, and ECTR is accounting for a growing proportion of surgeries. When adjusted for inflation, average reimbursement has decreased, with a greater decrease among ECTR. Orthopedic surgeons perform most of such surgeries. These trends are important to assure adequate resource allocation as treating carpal tunnel becomes more common among the aging Medicare population.

Background: Ganglion cysts are benign soft-tissue tumors that are most commonly found in the wrist. Within the wrist, 60% to 70% of ganglion cysts occur on the dorsal side and 20% to 30% occur on the volar side 1 . Although ganglia arise from multiple sites over the dorsal wrist, dorsal ganglia most commonly originate at the scapholunate joint 2,3 . Open excision is the standard surgical treatment for dorsal wrist ganglia. This procedure is considered when symptoms such as pain and range-of-motion deficits begin to impact activities of daily living. Description: Open excision of a dorsal wrist ganglion is commonly performed with the patient under general anesthesia or a regional block. The patient is placed in the supine position, and a tourniquet is applied on the affected upper limb. After outlining the periphery of the palpable ganglion, the surgeon makes a transverse or longitudinal incision over the ganglion. The surgeon then begins a deep dissection, dissecting through the subcutaneous tissue and isolating the ganglion while avoiding any rupture, if possible. Once the cyst has been identified, extensor tendons surrounding the cyst are retracted and the cyst and stalk are mobilized. The cyst and stalk are subsequently excised, and the wound is closed 4 . Alternatives: Alternative treatments for dorsal wrist ganglia include nonoperative interventions such as observation, aspiration, controlled rupture, and injection. Operative treatments include arthroscopic and open dorsal wrist ganglion resections. Rationale: Although nonoperative treatment can produce successful outcomes, the various modalities have been associated with recurrence rates ranging from 15% to 90% 4 . As a result, surgical excision remains the gold standard of treatment and is typically indicated when weakness, pain, and limited range of motion interfere with activities of daily living. Among surgical interventions, arthroscopic excision is a minimally invasive procedure that has become more common because of the reduced scarring and faster recovery 5 . However, open excision, which does not involve complex equipment, is regarded as the standard among surgical treatments. Although the rates of recurrence for arthroscopic versus open dorsal ganglion excision are similar, arthroscopic excision is less effective with regard to pain relief 5,6 . This difference in pain relief could potentially be the result of the neurectomy of the posterior interosseous nerve in an open excision. In contrast, an arthroscopic procedure may provide less relief of pain from the posterior interosseous nerve stump attaching to the scarred capsule 5 . Expected Outcomes: Open excision of a dorsal wrist ganglion is a safe, reliable procedure. The recurrence rate after open excision is similar to that after arthroscopic excision and significantly lower recurrence than that after ganglion cyst aspiration 6,7 . Additionally, not all ganglion cysts can be aspirated. In a retrospective study assessing the risk of recurrence after open excision of ganglion cysts in 628 patients, researchers reported a recurrence rate of 4.1% among the 341 who underwent open dorsal ganglion excision. Furthermore, the authors reported male sex and less surgeon experience as significant risk factors for cyst recurrence 8 . In a study assessing outcomes of open dorsal ganglion excision in 125 active-duty military personnel, researchers reported a recurrence rate of 9%. More notably, the researchers found persistent pain at 4 weeks postoperatively in 14% of the participants. The authors recommended that patients whose daily activities require forceful wrist extension, such as athletes and military personnel, should be counseled on the potential functional limitations and residual pain from open dorsal wrist ganglion excision 9 . Important Tips: When conducting an open excision, it is beneficial to identify the stalk of the cyst, allowing the surgeon to excise the complete ganglion complex and prevent recurrence. For large cysts that adhere to the surrounding soft tissue, it is helpful to rupture the ganglion in order to facilitate an easier deep dissection. Excising the scapholunate interosseous ligament could possibly lead to scapholunate dissociation and instability. The posterior interosseous nerve courses past the 4th dorsal compartment and may be resected during the deep dissection.

Background: Open trigger finger release is an elective surgical procedure that serves as the gold standard treatment for trigger digits. The aim of this procedure is to release the A1 pulley in a setting in which the pulley is completely visible, ultimately allowing the flexor tendons that were previously impinged on to glide more easily through the tendon sheath. Although A1—or the first annular pulley—is the site of triggering in nearly all cases, alternative sites include A2, A3, and the palmar aponeurosis 1 . Description: Typically, the surgical procedure can be conducted in an outpatient setting and can vary in duration from a few minutes to half an hour. The surgical procedure involves the patient lying in the supine position with the operative hand positioned to the side. A small incision, ranging from 1 to 1.5 cm, is made on the volar side of the hand, just proximal to the A1 pulley in the skin crease in order to minimize scarring. Once the underlying neurovascular structures are exposed, the A1 pulley is released longitudinally at least to the level of the A2 pulley, followed by decompression of the flexor tendons that were previously impinged on. In order to confirm the release, the patient is asked to flex and extend the affected finger. The wound is irrigated and closed once the release is confirmed by both the patient and surgeon. Alternatives: Aside from an open release, trigger finger can be treated nonoperatively with use of splinting and corticosteroid injection. Alternative operative treatments include a percutaneous release, which involves the use of a needle to release the A1 pulley 2 . Trigger finger can initially be treated nonoperatively. If unsuccessful, surgical intervention is considered the ultimate remedy 2 . Rationale: Because of their efficacious nature, corticosteroid injections are indicated preoperatively, particularly in non-diabetic patients 3 . Splinting is often an appropriate treatment option in patients who wish to avoid a corticosteroid injection 1 . However, if nonoperative treatment modalities fail to resolve pain and symptoms, surgical intervention is indicated 2 . In comparison with a percutaneous trigger finger release, an open release provides enhanced exposure and may be safer with respect to avoiding iatrogenic neurovascular injury 2 . However, in a randomized controlled trial, Gilberts et al. found no difference in the rates of recurrence when comparing open versus percutaneous trigger finger release 4 . Expected Outcomes: With reported success rates ranging from 90% to 100%, the open release of the A1 pulley is considered a common procedure associated with minimal complications 2 . Complications of the procedure were assessed in a retrospective analysis of 43 patients who underwent 78 open trigger releases performed by 1 surgeon. In that study, the authors reported a minor complication rate of 28% and a major complication rate of 3% 5 . Specifically, the 2 major complications noted by the authors were a synovial fistula and a proximal interphalangeal joint arthrofibrosis. In a larger study that included 543 patients who underwent 795 open trigger releases, the authors reported a minor complication rate of 9.6% and major complication rate of 2.4% 6 . Furthermore, the most common complications involved persistent stiffness, swelling, or pain. In that analysis, the authors suggested that sedation, male gender, and general anesthesia may be associated with greater risk 6 . Important Tips: At the discretion of the surgeon, a longitudinal, transverse, or oblique incision is made directly on top of the tendon at the level of the metacarpophalangeal joint, which is the preferred incision site because it provides maximal accessibility to the A1 pulley. Local anesthesia is preferred because it allows the patient and surgeon to confirm the release immediately. If conducting an open trigger release on the thumb, the surgeon should identify and protect the radial digital nerve, which courses directly over the A1 pulley.

Abstract Background Although uncommon, nontuberculous mycobacterial infections (NTMI) of the upper extremity cause significant morbidity based on their natural history, delay in diagnosis, prolonged duration of antimicrobial therapy often combined with surgical debridement, and functional loss. Herein we describe our experience with such infections. Methods Records for adult patients from two academic, tertiary facilities with culture-proven NTMI involving the upper extremity were retrospectively reviewed. Demographic information, co-morbidities, laboratory and microbiological evaluation, management, and outcomes were extracted. Patients were analyzed based on pathogen identified and immune suppression. Results 77 patients were identified. The mean age was 59 years and 65% of patients were male. 48% reported a preceding injury, with the hand being most frequently involved (58%). 41% were considered immune compromised; 19% of them were organ transplant recipients. Mean symptom duration prior to presentation was 203 days. Mean time to culture identification was 33 days, and 25 different species of NTM were identified (subcategorized as rapid or slow growers). 77% had solitary lesions, with cutaneous/subcutaneous location as the most common site. All patients underwent surgical debridement with four undergoing amputation to control infection. 69% received combination antimicrobial therapy for a mean duration of 184 days. Immunosuppressed patients were treated with antimicrobial therapy for a longer duration (mean 243 vs 155 days). One-third of patients experienced complications and/or recurrence regardless of organism type. Conclusion NTMI of the upper extremity is often misdiagnosed leading to significant delays in appropriate management. Knowledge of its protean manifestations and early consideration in the differential diagnosis of chronic, painful swelling of the hand or wrist, nodular or inflammatory lesions, or septic arthritis is crucial. A low threshold for surgical or biopsy with specimens sent for histopathology as well as microbiologic analysis is warranted. A combined approach with surgical debridement and prolonged combination antimicrobial therapy is necessary for optimal outcomes; however, adverse reactions from such therapy are commonly encountered.

Background: The authors’ purpose was to evaluate the histopathology of flexor tenosynovium in true, idiopathic recurrent carpal tunnel syndrome for the presence of abnormal inflammatory or pathologic findings that might explain causation or that differ from those previously described for primary, idiopathic carpal tunnel syndrome. Methods: Thirty-five patients (19 women and 16 men; mean age, 72 years) underwent open revision carpal tunnel release a mean 13 years (range, 0.5 to 30 years) after primary carpal tunnel release. Recurrence was confirmed by recurrent symptoms, positive provocative tests, and electrodiagnostic testing. All patients underwent tenosynovial biopsy, including Congo red staining for amyloid. Results: Histopathologic findings demonstrated noninflammatory, fibrous connective tissue in 31 of 35 patients (89 percent); and mild, chronic inflammation (without granulomas) in four of 35 patients (11 percent). Nine of 35 patients (26 percent) had positive results for amyloid, with a statistically higher incidence in men (p = 0.03) and advanced age (p = 0.02). Subtyping performed in eight of nine amyloid-positive specimens confirmed seven cases of transthyretin-type amyloid typically seen in localized (senile) amyloidosis and one case of light-chain amyloid in a patient who was subsequently diagnosed with myeloma. Conclusions: Flexor tenosynovium in patients with recurrent carpal tunnel syndrome does not appear to be substantially different histologically from that previously described in primary idiopathic carpal tunnel syndrome, although a slightly higher prevalence of amyloid was seen in this group (especially older men). No patients have developed systemic amyloidosis. Routine biopsy of tenosynovium in idiopathic, recurrent carpal tunnel syndrome is unnecessary.
