Investigation Into the Effects of Intra-Articular Steroid on Post-Traumatic Osteoarthritis in Distal Radius Fractures: A Randomized Controlled Pilot Study.

PURPOSE: The aim of this prospective, randomized, controlled, double-blinded pilot study was to determine the rates of post-traumatic osteoarthritis and assess joint space width in the presence or absence of a single intra-articular injection of corticosteroid after an acute, intra-articular distal radius fracture (DRF). METHODS: Forty patients received a single, intra-articular, radiocarpal joint injection of 4 mg of dexamethasone (DEX) (n = 19) or normal saline placebo (n = 21) within 2 weeks of a surgically or nonsurgically treated intra-articular DRF. The primary outcome measure was minimum radiocarpal joint space width (mJSW) on noncontrast computed tomography scans at 2 years postinjection. Secondary outcomes were obtained at 3 months, 6 months, 1 year, and 2 years postinjection and included Disabilities of the Arm, Shoulder, and Hand; Michigan Hand Questionnaire; Patient-Rated Wrist Evaluation; wrist range of motion; and grip strength. RESULTS: At 2-year follow-up, there was no difference in mean mJSW between the DEX group (2.2 mm; standard deviation, 0.6; range, 1.4-3.2) and the placebo group (2.3 mm; standard deviation, 0.7; range, 0.9-3.9). Further, there were no differences in any secondary outcome measures at any postinjection follow-up interval. CONCLUSIONS: Radiocarpal joint injection of corticosteroid within 2 weeks of an intra-articular DRF does not appear to affect the development of post-traumatic osteoarthritis within 2 years follow-up in a small pilot cohort. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Calcific Tendinitis of the Proximal Flexor Carpi Radialis in a Throwing Athlete.

Flexor carpi radialis tendinitis is a condition that almost exclusively affects the distal aspect of the tendon where it lies in a tight fibro-osseous tunnel. Tendinitis of the proximal aspect of the tendon at its myotendinous junction is extremely rare. Herein, we present a single case of calcific tendinitis of the flexor carpi radialis tendon at its myotendinous junction in a throwing athlete. Diagnostic challenges and treatments are discussed.

Pronated Grip View With Wrist Deviation: A Pilot Study on the Effect on Ulnocarpal Relationships.

BACKGROUND: We hypothesize that different positions of the wrist in the coronal plane makes the carpus susceptible to ulnar impaction. METHODS: We prospectively enrolled 10 adult volunteers and obtained fluoroscopic images of each wrist in 12 different positions using a standardized protocol. Distances from the ulna to the lunate (UL) and ulna to the triquetrum (UT) were digitally measured as was the portion of the lunate surface area that was uncovered (LUR) with wrist deviation. RESULTS: A wrist position of Pronation, Neutral Deviation, and Grip (P-ND-G) significantly shortened the ulnocarpal distance when compared to a position of Neutral Rotation, Neutral Deviation, and No Grip (NR-ND-NG). Radial deviation during pronation and gripping (Pronated, Radial Deviation, Gripping [P-RD-G]) resulted in the lowest mean UL distance (1.2 mm). UT distance was minimized by a position of ulnar deviation during a pronated grip (Pronated, Ulnar Deviation, Gripping [P-UD-G]) (3.1 mm). The lunate becomes more uncovered with radial deviation. CONCLUSION: Radial deviation minimizes the UL distance while ulnar deviation minimizes the UT distance during a wrist position of pronation and gripping. Further, there is more proximal lunate surface area uncoverage during all positions of radial deviation compared to ulnar deviation.

Defining the Digit-Specific Confluence of the A1 Pulley.

PURPOSE: Variations in the description of the flexor pulley system exist, particularly in whether the A1 and A2 pulleys represent discrete or confluent entities. This has potentially important clinical relevance at the time of A1 pulley release for symptomatic trigger finger, given the goal of adequate release without overrelease. The purpose of this study was to determine the relative prevalence of confluent A1 pulleys on a digit-by-digit basis employing 2.5× loupes alone, thereby simulating a clinical surgical environment. METHODS: Cadaveric anatomic specimens underwent flexor pulley system dissection under 2.5× loupe magnification by 2 hand surgeons. The presence of pulley confluence and length (measured from the proximal aspect to the distal aspect) was recorded and compared on a digit-to-digit basis. RESULTS: Forty-five digits, comprising 9 adult forearm or hand specimens (5 right and 4 left) obtained from 6 donors (4 men and 2 women, age: 67 ± 8 years), were dissected. A total of 19 confluent A1 pulleys were encountered, with notable digit-by-digit variation in the prevalence of confluent pulleys. There were 0 confluent pulleys observed in the thumb, compared with 6 confluent pulleys observed in the middle finger. The average overall A1 pulley length was 5.0 ± 1.5 mm, with a similar pulley length observed between the digits. CONCLUSIONS: A1 pulley confluence varies on a digit-to-digit basis, with no observed confluence in the thumb and the most common confluence observed in the middle finger. CLINICAL RELEVANCE: In the setting of intraoperatively observed pulley confluence, we suggest pulley release under traction in order to develop the plane between the A1 and A2 pulleys and, thus, confirm the complete and isolated release of the A1 pulley.

Ulnar Wrist Pain in a Tennis Player: Case Review and Discussion: A Team-Based Approach.

¼: Ulnar-sided wrist pain is a common cause of debilitating wrist pain in stick-handling athletes. Due to the complexity of surrounding anatomy, the evaluation and diagnosis can be challenging. ¼: Injury of the triangular fibrocartilage complex (TFCC) is the most common cause of ulnar-sided wrist pain. Repetitive, unrestricted pronosupination, wrist deviation, and axial-loading activity, such as in tennis, place substantial stress on the TFCC. ¼: The ulnotriquetral (UT) ligament is a palmar thickening of the ulnar capsule arising from the palmar radioulnar (PRU) ligament of the TFCC. When injured, the UT ligament can be a source of acute or chronic ulnar-sided wrist pain. The ligament can avulse off bone, can rupture completely, or can split longitudinally. ¼: Arthroscopic-assisted repair is a safe, reliable, and effective treatment for UT ligament split tears and peripheral TFCC tears. ¼: Although the benefit of a team-based approach may be realized by most patients, high-performing, stick-handling athletes are part of a unique population who execute repetitive, extraordinary wrist movements. The high demand and functional requirement expected of the wrists require a uniquely tailored approach to return them to the same level of competitive play.

Preoperative Antibiotics Influence Culture Yield in the Treatment of Hand, Wrist, and Forearm Infections.

When treating upper-extremity infections, clinicians frequently must decide whether to initiate antibiotics or delay them with the goal of optimizing culture yield at the time of surgical debridement. The purpose of this study was to determine whether the administration of preoperative antibiotics affects intraoperative culture yield and whether there is a "safe" interval prior to culture acquisition within which antibiotics can be administered without affecting culture yield. Methods: We conducted a retrospective review of 470 consecutive patients who underwent debridement for a presumed acute infection of the hand, wrist, or forearm at a single tertiary care center between January 2015 and May 2020. Data including patient demographics, mechanism of infection and affected body part(s), and details of antibiotic administration, including type and timing with respect to culture acquisition, were collected. Results: Three hundred and forty-one patients (73%) received preoperative antibiotics prior to debridement and culture acquisition. The rate of positive cultures among patients who received preoperative antibiotics was 81% compared with 95% among patients who did not receive preoperative antibiotics (p < 0.01; odds ratio, 4.73). Even a single dose of antibiotics imparted a significantly increased risk of obtaining negative intraoperative cultures, and an incremental increase in the likelihood of obtaining negative cultures was seen with each preoperative dose given up to 7 doses. We did not identify a "safe" interval of time between antibiotic administration and culture acquisition such that culture yield was not affected. Conclusions: Patients who received preoperative antibiotics for the treatment of upper-extremity infections were approximately 5 times more likely to have negative cultures at the time of debridement than those who did not receive preoperative antibiotics. This effect persisted regardless of the number of doses given or the interval between antibiotic administration and culture acquisition. Level of Evidence: Prognostic Level III.

Operative Treatment of Distal Radius Fractures in Patients With Parkinson Disease.

BACKGROUND: Owing to the many unique disease characteristics of Parkinson disease (PD)-namely resting tremors, muscular rigidity, and poor bone quality-we hypothesized that this patient population would have inferior outcomes with surgical management of acute distal radius fractures (DRFs) compared with the literature available on the general population. METHODS: This is a retrospective observational study performed at a single, level 1, academic center from 2001 to 2020 capturing all adult patients with an isolated, acute, and closed DRF that ultimately underwent operative treatment. International Classification of Diseases 10 codes were used to identify 30 patients for manual chart review. Several patient and fracture characteristics were accounted for and complications, reoperations, and failures of surgical intervention were recorded. RESULTS: There was a total of 7/30 failures (23%), 6/30 reoperations (20%), and 12 complications in 9/30 wrists (complication rate, 30%) at a mean latest follow-up of 11 months (1.2-158 months). Of the 7 failures, 5 were due to loss of reduction, and 2 of them were deep infections with mean time to failure of 8.3 weeks (range, 11 days-5.2 months). CONCLUSIONS: This study found a high rate of complications, reoperations, and early failure despite a short follow-up period and a small cohort of patients with PD treated surgically for a DRF. We recommend locked plating if suitable for the fracture type and early involvement of a multidisciplinary team to assist with medical optimization of PD to increase chances of a successful outcome.

Scapholunate ligament 360° procedure.

AIMS: The purpose was to evaluate early clinical, patient-reported, and radiological outcomes of the scapholunate ligament 360° tenodesis (SL 360) technique for treatment of scapholunate (SL) instability. METHODS: We studied the results of nine patients (eight males and one female with a mean age of 44.7 years (26 to 55)) who underwent the SL 360 procedure for reducible SL instability between January 2016 and June 2019, and who were identified from retrospective review of electronic medical records. Final follow-up of any kind was a mean of 33.7 months (12.0 to 51.3). Clinical, radiological, and patient-reported outcome data included visual analogue scale (VAS) for pain, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Mayo Wrist Score (MWS), and Patient-Rated Wrist Examination (PRWE). Means were analyzed using paired t-test. RESULTS: Before surgery, patients with SL instability were significantly impaired with respect to wrist flexion, extension, and grip strength (mean flexion, 51° (20° to 85°) vs 73° (45° to 90°); mean extension, 46° (15° to 70°) vs 66° (45° to 80°); mean grip strength, 25 kg (20 to 31) vs 50 kg (35 to 68) compared to the unaffected side). The mean SL gap (4.9 mm (2.3 to 7.3) vs 2.1 mm (1.6 to 2.9)) and mean SL angle (71° (59° to 105°) vs 50° (38° to 64°) were also significantly greater in the affected wrist. At final follow-up, there was mean improvement regarding clinical, radiological, and functional outcomes comparing preoperative to final postoperative values for the VAS for pain scale, QuickDASH, MWS, PRWE, and SL gap and SL angle. CONCLUSION: In our small series, the SL 360 procedure for reducible SL instability has favourable early clinical, patient-reported, and radiological outcomes at a mean of 33.7 months (12.0 to 51.3). The suture tape and tendon construct confers robust stability, permitting earlier mobilization without the inherent disadvantages of Kirschner wire stabilization.

Natural history of glenoid bone loss in primary glenohumeral osteoarthritis: how does bone loss progress over a decade?

INTRODUCTION: Progressive glenoid bone loss and humeral head subluxation occur in primary glenohumeral osteoarthritis (GHOA), but less is known about the rate and pattern by which this occurs. The purpose of this study was to determine how glenohumeral subluxation and glenoid bone loss changed over time in shoulders that underwent arthroplasty and had been evaluated with radiographs at 1 or more time points over the 5-15 years before arthroplasty. METHODS: We retrospectively identified 48 shoulders that had been evaluated with high-quality radiographs both before arthroplasty and at least once 5-15 years earlier. Axillary radiographs were used to classify glenoid morphology using the modified Walch classification on the oldest, most recent, and all intervening radiographs. The mean interval time between the oldest and most recent radiographs was 8.9 years (range 5-15 years). Nineteen patients had a single intervening radiograph (mean, 6.7 years from most recent radiograph; range 4.4-8.9 years), 6 patients had 2 (mean, 5.6 years; range 0.2-13.9 years), 3 had 3 (mean, 5 years; range 2.4-8.3 years), 2 had 5 (mean, 3.4 years; range 1.1-5.7 years), and 1 had 6 (0.5 years). RESULTS: Glenoid morphology on the earliest radiograph was classified as A1 in 22, A2 in 13, B1 in 1, B2 in 9, B3 in 1, and D in 2 shoulders. Walch A patterns identified on early radiographs most commonly maintained an A pattern over time, but 20% developed eccentric wear with 5 of 35 becoming B type and 2 of 35 becoming a D type before arthroplasty. All B-type glenoids remained B type. Classic progression of bone loss along the same concentric or eccentric "track" occurred 41% of the time, with 9 of 22 A1 glenoids becoming A2 glenoids, the only B1 glenoid becoming a B2 glenoid, and 56% (5/9) of B2 glenoids becoming B3 glenoids before arthroplasty. Only 15% (2/13) of A2 glenoids developed eccentric wear compared with 32% (7/22) of A1 glenoids. CONCLUSION: In primary GHOA, humeral head subluxation and glenoid bone loss do progress over time, but not universally and not always through the same pathway. Shoulders presenting with posterior subluxation (B types) remained posteriorly subluxed. Shoulders presenting with concentric arthritis developed an eccentric pattern 20% of the time. For concentric arthritis, progression of bone loss from A1 to A2 occurred 41% of the time. For eccentric arthritis, progression of bone loss from B2 to B3 occurred 56% of the time.

Problems of Eponymous Proportions: The History Behind Recognizing Forearm Instability Issues.

Three predictable patterns of forearm fracture-dislocation-Essex-Lopresti, Monteggia, and Galeazzi-can occur and are eponymously labeled for the investigators who appreciated their unique characteristics and offered a framework by which to understand them. Recognition of these injuries and subsequent investigation and increased understanding of these lesions have resulted in improved understanding about forearm anatomy and stability. Management of the component of instability differs based on the type of fracture-dislocation, the timing of intervention, and surgeon preference. Despite advances in understanding and treating these injuries, nuances of these lesions may remain challenging to modern-day surgeons.

Radiotherapy Does Not Impact Long-term Function Following Resection of Soft-tissue Sarcomas of the Hand.

BACKGROUND/AIM: Radiotherapy for soft tissue sarcomas (STS) of the hand is thought to be associated with poor function. The aim of this study was to compare the long-term functional outcome in patients with and without radiotherapy. PATIENTS AND METHODS: At long-term follow-up (mean 10±5 years), 33 (13 males, 20 female) patients, were alive for review. The mean patient age at surgery was 33±17 years and 13 (39%) patients received radiotherapy (mean dose 55±6 Gy). RESULTS: Postoperatively, the mean QuickDASH and MSTS93 were 7±8 and 92±8%, respectively. Comparing patients with and without radiotherapy, there was no difference (p>0.05) between the mean QuickDASH (5±5 vs. 8±9) or MSTS93 (93±9% vs. 91±8%). Surgical complication occurred more commonly in patients with radiotherapy (46% vs. 15%, p=0.10). CONCLUSION: The use of radiotherapy was associated with a higher rate of complications, however, was not associated with a worse long-term functional outcome in patients with hand STS.

Locking plate fixation of proximal humerus fractures in patients older than 60 years continues to be associated with a high complication rate.

BACKGROUND: Locking plate technology has increased the frequency of open reduction and internal fixation (ORIF) of proximal humerus fractures (PHF). A number of technical pearls have been recommended to lower the complication rate of ORIF. These pearls are particularly relevant for patients aged >60 years, when nonoperative treatment and arthroplasty are alternatives commonly considered. There have been few large, single-center studies on the modern application of this technology. METHODS: Between 2005 and 2015, a total of 173 PHFs in patients aged >60 years were treated at our institution with ORIF using locking plates. Failure was defined as reoperation or radiographic evidence of failure. Average follow-up was 6.1 years. RESULTS: There was an overall complication rate of 44%. The overall failure rate was 34% and correlated with fracture type: 26% failure rate in 2-part fractures (16 failures), 39% in 3-part fractures (23 failures), and 45% in 4-part fractures (11 failures). There was no difference between the failure rate with and without fibular allograft (33% vs. 34%). Most patients with radiographic or clinical failure did not undergo reoperation. The overall reoperation rate was 11% (14 patients). Seven percent of 2-part fractures (4 shoulders), 14% of 3-part fractures (8 shoulders), and 18% of 4-part fractures (2 shoulders) required reoperation. CONCLUSIONS: ORIF of PHFs with locking plates in patients aged >60 years resulted in a 44% complication and 34% failure rate. There was a trend toward higher complication and failure rates in older patients and more complex fractures. Refinement in fixation techniques and indications are necessary to optimize the surgical management of PHFs.

Capitellar Osteochondritis Dissecans Lesions of the Elbow: A Systematic Review of Osteochondral Graft Reconstruction Options.

PURPOSE: To systematically evaluate the outcomes and complications of osteochondral autograft transfer (OAT) and osteochondral allograft transplantation (OCA) for the surgical treatment of capitellar osteochondritis dissecans (OCD). METHODS: A literature search was conducted across 3 databases (PubMed, Cochrane, and CINAHL [Cumulative Index to Nursing and Allied Health Literature]) from database inception through December 2019 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Individual study quality was assessed using the Methodological Index for Non-randomized Studies scale. Studies were published between 2005 and 2019. RESULTS: Eighteen studies consisting of 446 elbow OCD lesions treated with OAT surgery were included. There was a single OCA study eligible for inclusion. Patient ages ranged from 10 to 45 years. Of the OAT studies, 4 used autologous costal grafts whereas the remainder used autografts from the knee. Outcome measures were heterogeneously reported. A significant improvement in Timmerman-Andrews scores from preoperatively to postoperatively was reported in 9 of 10 studies. Return-to-play rates to the preinjury level of competitive play ranged from 62% to 100% across 16 studies. Significant improvement in motion, most often extension, was noted in most studies. Reported complication, reoperation, and failure rates ranged from 0% to 11%, 0% to 26%, and 0% to 20%, respectively. When used, knee autografts resulted in low donor-site morbidity (Lysholm scores, 70-100). CONCLUSIONS: OAT surgery for large, unstable OCD lesions of the capitellum reliably produced good outcomes, few complications, and a high rate of return to competitive play. Complications are relatively uncommon, and donor-site morbidity is low. Less is known about the performance of OCA given the paucity of available literature. LEVEL OF EVIDENCE: Level IV, systematic review of Level II to IV studies.

Total Elbow Arthroplasty for Distal Humerus Fractures Provided Similar Outcomes When Performed as a Primary Procedure or After Failed Internal Fixation.

OBJECTIVES: To compare clinical and functional outcomes of total elbow arthroplasty (TEA) for distal humerus fractures (DHF) performed either as a primary procedure or after internal fixation. DESIGN: Retrospective, observational study. SETTING: Mayo Clinic, Rochester, MN (1998 through 2016). PATIENTS/PARTICIPANTS: Twenty-two TEA for acute DHF and 66 TEA after previous internal fixation. MAIN OUTCOME MEASUREMENTS: Primary outcome measures included the Mayo Elbow Performance Score and motion. Reoperation rates and complications were also compared. RESULTS: The mean time between internal fixation and arthroplasty was 7.3 years, and the main indications for conversion to TEA were nonunion (36%) and posttraumatic osteoarthritis (32%). There were female predominance (70%) and significant differences in age (74 years vs. 60 years, P < 0.0001) and tobacco use (0 vs. 23%; P = 0.02) between the primary and the salvage cohorts, respectively. Cohort demographics were otherwise comparable. TEA provided similar outcomes in both cohorts in terms of the Mayo Elbow Performance Score (acute 85, salvage 81, P = 0.32) and motion (acute 95/82/75 degrees, salvage 112/81/72 degrees in ulnohumeral/pronation/supination, P = 0.07/P = 0.85/P = 0.65). Reoperation rates were also similar (36% acute vs. 39% salvage, P = 1.00). Aseptic loosening (2 acute, 8 salvage) and deep infection (2 acute, 7 salvage) were the most common complications. CONCLUSIONS: The clinical outcomes and reoperation rates of TEA for DHF seem to be similar when performed as a primary procedure or as salvage after previous internal fixation. The benefit of avoiding elbow arthroplasty in the acute setting needs to be balanced with the potential for 2 surgical procedures if internal fixation was to be unsuccessful. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The router bit extraction technique for removing a well-fixed humeral stem in revision shoulder arthroplasty.

AIMS: A number of methods have been described to remove a well-fixed humeral implant as part of revision shoulder arthroplasty. These include the use of cortical windows and humeral osteotomies. The router bit extraction technique uses a high-speed router bit to disrupt the bone-implant interface. The implant is then struck in a retrograde fashion with a square-tip impactor and mallet. The purpose of this study was to determine the characteristics and frequency of the different techniques needed for the removal of a well-fixed humeral stem in revision shoulder arthroplasty. PATIENTS AND METHODS: Between 2010 and 2018, 288 revision shoulder arthroplasty procedures requiring removal of a well-fixed humeral component were carried out at a tertiary referral centre by a single surgeon. The patient demographics, indications for surgery, and method of extraction were collected. RESULTS: Of the 288 revisions, 284 humeral stems (98.6%) were removed using the router bit extraction technique alone. Four humeral stems (1.39%) required an additional cortical window. Humeral osteotomy was not necessary in any procedure. Most of the humeral stems removed (78.8%) were cementless. Of the four humeral stems that required a cortical window, three involved removal of a hemiarthroplasty. Two were cemented and two were cementless. CONCLUSION: The router bit extraction technique removed a well-fixed humeral component in a very high proportion of patients (98.6%). This method allows surgeons to avoid more invasive approaches involving a cortical window or humeral osteotomy, and their associated complications.

Melorheostosis Causing Compression of Common Peroneal Nerve at Fibular Tunnel.

BACKGROUND: Melorheostosis is a bone hyperostosis disorder characterized by flowing bone thought to occur in a sclerodermal distribution. These bony lesions often arise in soft tissues adjacent to joints. Pain arises from joint limitations and impingements, but diffuse pain can also occur. CASE DESCRIPTION: We present a case of a patient with symptomatic compression of the common peroneal nerve by an extraosseous hyperostotic tissue island in a patient with melorheostosis. CONCLUSIONS: Melorheostosis is a rare bone overgrowth syndrome that can lead to joint mobility limitations and pain. In specific locations, it can also lead to tethering and symptomatic compression of the peripheral nerves.

Osteochondritis dissecans lesions of the capitellum in overhead athletes: a review of current evidence and proposed treatment algorithm.

PURPOSE OF THE REVIEW: To review the most recent literature on osteochondritis dissecans (OCD) lesions of the capitellum in overhead athletes and describe a treatment algorithm based on current best evidence and surgeon experience. RECENT FINDINGS: Recent research has included larger cohort studies with longer follow-up as well as quality systematic reviews and meta-analyses. These studies have focused on understanding how lesion characteristics such as size, location, and appearance on advanced imaging can predict treatment success. Current literature continues to support nonoperative management for stable lesions. Operative intervention is generally required for unstable lesions and treatment strategies are largely dictated by lesion size and location: debridement or reparative techniques for small lesions while larger lesions or those in high-stress locations are better served by bone and/or cartilage restoration procedures. There has been a rising interest in the use of allograft materials and cell-based therapies. Overhead athletes are uniquely predisposed to capitellar OCD due to the nature of forces applied to the radiocapitellar joint during repeated activity in the overhead position. Despite improvements in operative techniques, successful use of alternative graft materials, and a better understanding of how lesion characteristics influence results, there is still much to learn about this challenging disorder. Future research should focus on comparing operative techniques, refining their indications, and further developing a reliable treatment algorithm that best serves the overhead athlete.

A Prospective, Randomized Trial of Splinting After Minicarpal Tunnel Release.

PURPOSE: To determine if any significant differences exist in patient-reported or clinical outcomes among 3 different postoperative orthotic regimens: no orthosis, removable orthosis, and plaster nonremovable orthosis-following miniopen carpal tunnel release (CTR) surgery for symptomatic isolated carpal tunnel syndrome. METHODS: A total of 249 patients received a miniopen CTR and were subsequently randomized into 1 of 3 orthotic regimens: 80, no orthosis; 83, removable orthosis; and 86, nonremovable orthosis-to be removed at the first postoperative visit 10 to 14 days later. Patient-reported outcomes included the quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) surveys, Levine-Katz Symptom Severity and Functional Status Scales, and Pain at Rest and in Action using the Numerical Pain Rating Scale. Clinical outcomes included wrist range of motion, grip, and lateral pinch strengths. All outcomes were evaluated bilaterally at 10 to 14 days, 6 weeks, and 3, 6, and 12 months after surgery by evaluators blinded to the assigned regimen. Demographic information was obtained before surgery, and complications were recorded throughout the study. RESULTS: There were no statistically significant differences in any patient-reported or clinical outcomes at any follow-up period except at 6 and 12 months: the lateral pinch strength of the nonremovable orthosis group with CTR in the dominant hand was weaker than both of the other groups. Patient demographic characteristics did not significantly influence the outcomes at any time. Scar tenderness was the most commonly observed complication followed by stiffness. There were 2 cases each of complex regional pain syndrome and superficial wound dehiscence and 1 case of wound infection that resolved with oral antibiotics. CONCLUSIONS: The postoperative orthotic regimen does not change any patient-reported outcome up to at least 12 months following miniopen CTR. Lateral pinch strength was weaker in the nonremovable orthosis group at 6 and 12 months. Our data do not support the use of any postoperative orthosis following routine miniopen CTR. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

Arthroscopic Partial Trapeziectomy With Soft Tissue Interposition for Symptomatic Trapeziometacarpal Arthritis: 6-Month and 5-Year Minimum Follow-Up.

PURPOSE: To determine if arthroscopic partial trapeziectomy (APT) and soft tissue interposition arthroplasty is an effective treatment for symptomatic trapeziometacarpal arthritis. METHODS: We retrospectively evaluated 30 consecutive patients with symptomatic isolated trapeziometacarpal arthritis, Eaton-Littler stages II and III. Treatment consisted of an APT with soft tissue interposition utilizing an acellular dermal matrix as the interposition material. At a minimum of 6 months and 5 years after surgery, Numeric Pain Rating Scale (NPRS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), grip strength, oppositional and appositional pinch strengths, arthroplasty space, and thumb range of motion (ROM) were evaluated. RESULTS: At 6-month minimum follow-up, 30 of 30 patients reported a significant reduction in pain; preoperative NPRS averaged 8.2 and decreased to 1.3. Average QuickDASH score was 17.5. Twenty-nine of 30 thumbs could adduct fully in the plane of the palm. Twenty-four patients were available for 5-year minimum follow-up. Average QuickDASH score measured 8.9, whereas pain (mean NPRS, 0.8), grip, and pinch strengths were not significantly different from the 6-month assessment. There was a small reduction in arthroplasty space at 5-year follow-up that did not affect clinical outcome measures. Thumb ROM did not change between the 6-month and the 5-year follow-up. Complications were rare. CONCLUSIONS: An APT with interposition arthroplasty utilizing an acellular dermal matrix as the interposition material is a safe and reliable procedure with satisfactory outcomes at short- and long-term follow-up. Pain, strength, QuickDASH, and ROM do not significantly change between the 6-month and the 5-year follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
