DRUJ Capsular Release for Forearm Rotational Limitation: Surgical Technique and Case Series.

BACKGROUND: Forearm stiffness can be caused by distal radioulnar joint (DRUJ) capsular contractures, which can occur after trauma such as a distal radius fracture. In this setting, a DRUJ capsular release may help improve forearm rotation, but the long-term functional outcomes remain unknown. The purpose of this case series is to investigate the short-term improvement in total pronosupination arc range of motion and long-term patient-reported outcomes (PROs) after DRUJ capsular release. METHODS: We performed a retrospective review of consecutive patients who underwent DRUJ capsular release. Range of motion prior to surgery and at final short-term follow-up was collected and analyzed with a Wilcoxon signed-rank test. Patient-reported outcomes including QuickDASH and Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) scores were obtained as medians with interquartile range (IQR), while patient satisfaction was measured on a 4-point Likert scale. RESULTS: Five patients met the inclusion criteria with a median short-term follow-up of 5.5 (IQR: 4.3-10.3) months. The median preoperative supination was 25° (IQR: 0°-35°), and the median postoperative supination was 50° (IQR: 40°-60°; P = .03). The median preoperative pronation was 45° (IQR: 10°-60°), and the median postoperative pronation was 70° (IQR: 60°-80°; P = .04). After the long-term median follow-up of 10.9 (IQR 9.7-11.2) years, all the patients were satisfied or very satisfied with the results of the surgery. The median QuickDASH score was 13.6 (IQR: 9.1-20.5), and the median PROMIS UE score was 46.5 (IQR: 43.8-47.7). CONCLUSIONS: Distal radioulnar joint capsular release can improve pronation and supination in patients with posttraumatic forearm stiffness and is associated with high long-term patient satisfaction.

Self-Reported Physical Function and Grit Are Not Correlated in Patients Who Undergo Open Reduction Internal Fixation for Distal Radius Fractures.

PURPOSE: "Grit" is defined as the perseverance and passion for long-term goals. Thus, grittier patients may have a better function after common hand procedures; however, this is not well-documented in the literature. Our purpose was to assess the correlation between grit and self-reported physical function among patients undergoing open reduction internal fixation (ORIF) for distal radius fractures (DRFs). METHODS: Between 2017 and 2020, patients undergoing ORIF for DRFs were identified. They were asked to complete the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire before surgery and at 6 weeks, 3 months, and 1 year after surgery. The first 100 patients with at least 1-year follow-up also completed the 8-question GRIT Scale, a validated measure of passion and perseverance for long-term goals measured on a scale of 0 (least grit) to 5 (most grit). The correlation between the QuickDASH and GRIT Scale scores was calculated using Spearman rho (ρ). RESULTS: The average GRIT Scale score was 4.0 (SD, 0.7), with a median of 4.1 (range, 1.6-5.0). The median QuickDASH scores at the preoperative, 6-week postoperative, 6-month postoperative, and 1-year postoperative time points were 80 (range, 7-100), 43 (range, 2-100), 20 (range, 0-100), and 5 (range, 0-89), respectively. No significant correlation was found between the GRIT Scale and QuickDASH scores at any time. CONCLUSIONS: We found no correlation between self-reported physical function and GRIT levels in patients undergoing ORIF for DRFs, suggesting no correlation between grit and patient-reported outcomes in this context. Future studies are needed to investigate the influence of individual differences in character traits other than grit on patient outcomes, which may help better align resources where needed and further the ability to deliver individualized, quality health care. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Are There More Radiolucent Lines in Patients Who Underwent Total Knee Arthroplasty With or Without a Tourniquet During Cementation at 5 to 8 Years After Surgery?

BACKGROUND: This study investigated the presence and progression of radiolucent lines (RLLs) after cemented total knee arthroplasty (TKA) with or without tourniquet use. METHODS: There were 369 consecutive primary cemented TKAs with 5 to 8 years of follow-up. A tourniquet was used during component cementation in patients who underwent surgery from January 3, 2006, to March 31, 2010. No tourniquet was used from August 14, 2009, to October 14, 2014. There were 192 patients in the tourniquet group (TQ) and 177 patients in the no tourniquet group (NQ). Patient demographics, reoperations, and complications were recorded. RLLs were identified on anteroposterior, lateral, and skyline x-rays at 1, 2, and 5 to 8 years postoperatively using the modern knee society radiographic evaluation system. Demographics, reoperations, complications, and RLLs were compared. Age, sex, and body mass index were similar between groups. Mean tourniquet time in TQ was 11 minutes (range, 8 to 25). RESULTS: The presence of RLLs differed between groups, with 65% of TQ knees having RLLs under any part of the prostheses versus 46% of NQ knees (P < .001). The progression of RLL >2 mm occurred in 26.0% of knees in TQ and 16.7% of knees in NQ (P = .028). There were 13 TKAs that underwent subsequent revision surgery. There was no statistically or clinically significant difference in revision rate between groups (7 revisions in TQ, 6 in NQ, P = .66). CONCLUSION: Less RLLs were identified in NQ versus TQ. There were no statistically or clinically significant differences in revision rates between the NQ and TQ groups at 5 to 8 years.

Posteriorly Displaced Radial Head Fractures May Represent the Footprint of an Elbow Dislocation or Subluxation as a Variant of Modified Mason Type 4.

Background: The purpose of this case series is to describe surgical decision making and clinical outcomes in posteriorly displaced radial head fractures with a major fragment (more than 50% of the head) located behind the humeral condyle. We also document the outcome of open reduction and internal fixation of completely displaced radial head fractures. Methods: A retrospective review of the ICUC® (Integrated Comprehensive Unchanged Complete) database was performed between 2012 and 2020. Patients were included if preoperative radiographs demonstrated a major radial head fracture fragment located posterior to the humeral condyle and a minimum of 2-year follow-up data was available. Results: Ten patients met inclusion criteria. Two patients had an associated elbow dislocation whereas 8 patients did not. All patients were found to have disruption of the lateral collateral ligament complex intraoperatively. Nine radial head fractures were successfully fixed with interfragmentary screws. One multi-fragmented radial head fracture could not be successfully stabilized with interfragmentary screw fixation and was resected. The average time to final follow-up was 4.8 years (range 2.2-8.1). At final follow-up, 6 patients demonstrated radiographic evidence of a healed radial head, 1 patient had avascular necrosis, and 2 had post-traumatic arthritis. None demonstrated radiographic instability. The average functional score was 0.64 (SD 0.81) and pain score was 0.45 (SD 0.93). The average elbow extension was 8 degrees (SD 11), elbow flexion was 139 degrees (SD 6), forearm supination was 60 degrees (SD 27), and forearm pronation was 69 degrees (SD 3). Conclusion: Recognition of a posteriorly displaced radial head fracture is essential, as it may be an indirect sign of elbow instability. This instability should be addressed during surgical intervention.

The Effect of an Electronic Prescribing Policy for Opioids on Physician Prescribing Patterns Following Common Upper Extremity Procedures.

Purpose: We evaluated physician prescribing patterns before and after the implementation of a state-mandated opioid electronic prescribing (ePrescribing) program after 4 common outpatient hand surgeries. Specifically, we aimed to answer the following: (1) is there a change in the number of opioids prescribed after the institution of ePrescribing for carpal tunnel release (CTR), ganglion excision, distal radius fracture (DRF) open reduction internal fixation (ORIF), and carpometacarpal (CMC) arthroplasty and (2) what factors are associated with an increased number of tablets or total morphine milligram equivalents (MMEs) prescribed. Methods: We retrospectively reviewed patients who underwent CTR, ganglion excision, DRF ORIF, or CMC arthroplasty and analyzed the number of tablets and MMEs prescribed before and after the policy implementation, as well as which factors were associated with an increased total number of opioid tablets and MMEs prescribed. Results: A total of 428 patients were included. After policy implementation, there was a significant decrease in MMEs prescribed for ganglion excision (68 [SD, 45] vs 50 [SD, 60], P = .03) and CMC arthroplasty (283 [SD, 147] vs 217 [SD, 92], P < .01). There was also a significant decrease in the total number of tablets prescribed for ganglion excision (11 [SD, 5.7] vs 6.8 [SD, 8.0], P < .01), CMC arthroplasty (36 [SD, 13] vs 29 [SD, 12], P < .01), and DRF ORIF (31 [SD, 8.6] vs 28 [SD, 8.5], P = .04). The number of patients receiving any opioid prescription also significantly decreased following CTR (30% vs 51%, P = .03) and ganglion excision (11% vs 53%, P < .01). Conclusions: The initiation of state-mandated ePrescribing was associated with a decreased number of opioids-both MMEs and tablets-prescribed after surgery by hand surgeons for a variety of common procedures. Furthermore, a greater percentage of patients received no opioid prescriptions after ePrescribing. These findings support the value of ePrescribing as a potential tool to further decrease excess opioid prescriptions. Type of study/level of evidence: Therapeutic III.

Using the QuickDASH to Model Clinical Recovery Trajectory After Operative Management of Distal Radius Fracture.

Purpose: There is a paucity of literature examining the trajectory of meaningful clinical improvement after distal radius fracture (DRF) fixation. We sought to answer the following questions: (1) When do patients meet the minimum clinically important difference (MCID) in the Quick-Disabilities in Arm, Shoulder, and Hand questionnaire (QuickDASH) score change after DRF fixation? (2) What gains in terms of number of MCIDs achieved (as measured by QuickDASH) do patients make as they recover from DRF fixation? (3) What patient and injury factors are characteristic of patients who meet or do not meet the average recovery trajectory? Methods: We performed a retrospective review of an institutional database of DRF patients treated with operative fixation. The change in QuickDASH scores from before surgery to approximate follow-up intervals of 0 to 2 months, 3 to 6 months, and a minimum of 9 of 12 months was assessed, in which a delta of 14 reflected the MCID. The change in QuickDASH score from before surgery to each follow-up interval was divided by 14 to determine the number of MCIDs, representing appreciable clinical improvement. Patient characteristics were compared between those who did and did not reach average levels of clinical improvement. Results: The study included 173 patients. Mean QuickDASH score before surgery was 74 (SD, 19; range, 0-100). After surgery, this improved to 50 (SD, 24; range, 0-100) by 0 to 2 months, 22 (SD, 22; range, 0-98) by 3 to 6 months, and 9.8 (SD, 15; range, 0-75) by a minimum of 9 to 12 months. Overall, 96% of patients reached the MCID by 1 year. Mean cumulative number of MCIDs achieved (ie, number of 14-point decreases in QuickDASH score) at each interval was 1.57, 3.64, and 4.43, respectively. Assuming 4.43 represents maximum average improvement at 1 year, patients achieved 35% (1.57 of 4.43) of recovery from 0 to 2 months after surgery and 82% (3.64 of 4.43) of recovery by 3 to 6 months after surgery. There appeared to be no difference in terms of age, sex, or body mass index with respect to these findings. Conclusions: Overall, 96% of patients undergoing DRF fixation will achieve one QuickDASH MCID by 1 year after surgery. Patients achieved over 80% of total expected functional improvement by 3 to 6 months after surgery, which appeared to be irrespective of age, sex, or body mass index. Type of study/level of evidence: Therapeutic IV.

Upper Extremity Fragility Fractures.

The population of elderly patients is rapidly increasing in the United States and worldwide, leading to an increased prevalence of osteoporosis and a concurrent rise in fragility fractures. Fragility fractures are defined as fractures involving a low-energy mechanism, such as a fall from a standing height or less, and have been associated with a significant increase in the risk of a future fragility fracture. Distal radius fractures in the elderly often present earlier than hip and vertebral fractures and frequently involve underlying abnormalities in bone mass and microarchitecture. This affords a unique opportunity for upper extremity surgeons to aid in the diagnosis and treatment of osteoporosis and the prevention of secondary fractures. This review aims to outline current recommendations for orthopedic surgeons in the evaluation and treatment of upper extremity fragility fractures.

Biofilms in Periprosthetic Joint Infections: A Review of Diagnostic Modalities, Current Treatments, and Future Directions.

As the number of total joint arthroplasties continues to rise, periprosthetic joint infection (PJI), a significant and devastating complication of total joint arthroplasty, may also increase. In PJI, bacterial biofilms are formed by causative pathogens surrounded by extracellular matrix with relatively dormant cells that can persist, resulting in a barrier against the host immune system and antibiotics. These biofilms not only contribute to the pathogenesis of PJI but also result in diagnostic challenges, antibiotic resistance, and PJI treatment failure. This review discusses the development of biofilms and key features associated with biofilm pathogenicity in PJI, current PJI diagnostic methods and their limitations, and current treatment options. Additionally, this article explores novel approaches to treat PJI, including targeting persister bacteria, immunotherapy, antimicrobial peptides, nanoparticles, and bacteriophage therapy. Biofilm eradication can also be achieved through enzymatic therapy, photodynamic therapy, and ultrasound. Finally, this review discusses novel techniques to prevent PJI, including improved irrigation solutions, smart implants with antimicrobial properties, inhibition of quorum sensing, and vaccines, which may revolutionize PJI management in the future by eradicating a devastating problem.
