Abstract
BACKGROUND Ulnar shortening osteotomy using various osteotomy sites, osteotomy methods, and surgical techniques with a variety of implants has been reported, but nonunion rates and the duration of bone healing are not uniform by the authors. The purpose of this study was to investigate the duration of bone healing and nonunion ratio in patients who underwent ulnar shortening osteotomy by a 5-hole nonlocking plate with a simple transverse osteotomy for ulnar impaction syndrome and to determine the correlation between the gap length of the osteotomy site and the duration of bone healing. METHODS We assessed patients who underwent ulnar shortening osteotomy for ulnar impaction syndrome using a 5-hole nonlocking plate fixation followed by a simple transverse osteotomy between July 2012 and October 2021. This study was a case series study, and the level of evidence was IV. RESULTS A total of 80 patients were included. The mean age of the patients was 46.7 years, and 46 patients were men. The average bone union period was 41.8 ± 18.7 weeks. The correlation between the gap length of the osteotomy site and the duration of bone union of the osteotomy site was not significant. The nonunion ratio of our method was 2.5%. CONCLUSION The nonunion rate of our ulnar shortening osteotomy with a simple transverse osteotomy and a 5-hole nonlocking plate was comparable to that in previous reports, but our method required slightly longer periods for bone union. There was no correlation between the gap length of the osteotomy and the duration of bone union. LEVEL OF EVIDENCE Level IV (Case series).

Abstract
BACKGROUND Wrist pain on the ulnar side is often caused by ulnar impaction syndrome (UIS). Idiopathic UIS requires surgical treatment when conservative treatment fails. The 2 main surgical procedures used are the wafer procedure and ulnar shortening osteotomy (USO) of the metaphysis or diaphysis. This review aimed to analyze comparative studies of the 2 procedures in UIS to determine clinical outcomes and complications. METHODS One prospective and 5 retrospective comparison trials were retrieved from the PubMed, Embase, and Cochrane Library databases. The primary outcomes were treatment effectiveness; pain visual analog scale (VAS), disabilities of the arm, shoulder, and hand (DASH) score, Mayo wrist, and Darrow scores. The incidence of postoperative complications formed the secondary outcome. RESULTS The selected studies included 107 patients who underwent the wafer procedure (G1) and 117 patients who underwent USO (G2). The wafer procedure had the benefits of less postoperative immobilization and an early return to work. However, there were no significant differences in the postoperative pain improvement and functional scores. All 6 studies reported high total complication rates and reoperation with USO. The most frequent complication was implant-related discomfort or irritation; subsequent plate removal was the most common reason for a secondary operation. CONCLUSIONS There was no difference in pain improvement or the postoperative functional score between the groups. Nevertheless, postoperative complications were the major pitfalls of USO. As the specialized shortening system advances further, a high-level study will be necessary to determine the surgical option in UIS.

Abstract
PURPOSE Ulnar shortening osteotomy (USO) is commonly performed to alleviate pathologies causing ulnar-sided wrist pain. Surgical complications include nonunion and hardware removal, with rates up to 18% and 45%, respectively. The primary objective of the study was to report the overall complication rate of USO. The secondary objective was to identify risk factors for complications. METHODS A retrospective multicenter cohort review was undertaken, including six Canadian cities over a 6-year period (January 2013-December 2018). Chart review was used to collect demographic data, surgical technique, implant used, and postoperative complications. Descriptive statistics of demographics and operative characteristics, including plate positioning, type of osteotomy, plate type, and ulnar variance (mm), were analyzed. Univariate analyses were used to select predictor variables for nonunion and hardware removal. These predictor variables were then entered into an adjusted multivariable logistic regression model. RESULTS A total of 361 USOs were performed. Mean age was 46 ± 16 years (60.7% men). The overall complication rate was 37.1%, hardware removal rate was 29.6%, and nonunion rate was 9.4%. There was a workers' compensation claim associated with 21.6% of all complications, and it was a risk factor for both hardware removal (odds ratio [OR] = 3.81) and nonunion (OR = 2.88). Neither smoking nor diabetes was associated with complication rates. Seventy percent of plates were placed volarly, 25.5% dorsally, and 3.9% directly ulnar. Osteotomies were oblique in 83.7% of cases and transverse in 15.5%. Adjusted multivariate regression analysis revealed that younger age (OR = 0.98) was a risk factor for hardware removal and male sex (OR = 0.40) was a risk factor for nonunion. A surgical factor associated with hardware removal was direct ulnar plate placement (OR = 9.93). No surgical factors were associated with nonunions. CONCLUSIONS There are substantial rates of complications with USOs. Direct ulnar plate placement should be avoided. Patients should be thoroughly counseled on the risks of complications prior to proceeding with USO. LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Unstable fractures of the distal radius fractures (DRFs) may result in malunion, usually consisting of subsequent shortening and angular deviations. Ulnar shortening osteotomy (USO) is assumed to be a simpler procedure than radial correction osteotomy, resulting in fewer complications and comparable outcomes. The aim of this study was to identify the best surgical technique to perform USO to restore distal radioulnar joint congruency after DRF malunion. METHODS A systematic review of the literature is performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines in February 2022 to identify studies reporting outcomes and surgical technique for isolated USO. The primary outcome was complication rates. Secondary outcomes included functional, radiologic, and patient-rated outcomes. The methodological index for nonrandomized studies criteria were used to assess the quality of evidence. RESULTS Included were 12 cohorts (185 participants). Due to substantial heterogeneity, a meta-analysis could not be performed. The overall complication rate was 33% (95% confidence interval, 16% to 51%). The most reported complication was implant irritation (22%), often requiring removal of the implant (13%). Only 3% nonunions were mentioned. Functional and patient-rated outcomes improved in most patients after USO. Quality of evidence of the papers was low to very low. Common methodological flaws were related to retrospective research. CONCLUSION No evident differences in complication rates and functional outcomes between the surgical techniques were observed. Based on this literature, most complications are related to implant irritation. Nonunion and infection rates were rare. Therefore, a surgical technique with a buried implant might be preferred. This hypothesis requires further investigation.

Abstract
PURPOSE Ulnar shortening osteotomy can be used to treat ulnar impaction syndrome and other causes of ulnar wrist pain. Distal metaphyseal ulnar shortening osteotomy (DMUSO) is one technique that has been proposed to reduce the complications seen with a diaphyseal USO or a wafer resection. However, to our knowledge, the optimal fixation construct for DMUSO has not been studied. We sought to characterize the biomechanical stiffness and rotational stability of different DMUSO constructs. METHODS A DMUSO was performed on 40 human cadaveric ulnas using 4 different fixation constructs (10 specimens per group): one 3.0 mm antegrade screw; two 2.2 mm antegrade screws; one 3.0 mm retrograde screw; and two 2.2 mm retrograde screws. Biaxial testing using axial load and cyclical axial torque was performed until failure, defined as 10° of rotation or 2 mm displacement. Specimens were assessed for stiffness at failure. Bone density was assessed using the second metacarpal cortical percentage. RESULTS Bone density was similar between all 4 testing groups. Of the 4 groups, the 2 antegrade screw group exhibited the highest rotational stiffness of 232 ± 102 Nm/deg. In paired analysis, this was significantly greater than 1 retrograde screw constructs. In multivariable analysis, 2-screw constructs were significantly stiffer than 1 screw and antegrade constructs were significantly stiffer than retrograde. Maximum failure torque did not differ with orientation, but 2 screws failed at significantly higher torques. CONCLUSION Using 2 screws for DMUSO fixation constructs may provide higher stiffness and maximum failure torque, and antegrade screw constructs may provide more stiffness than retrograde constructs. CLINICAL RELEVANCE Antegrade screw fixation using 2 screws may provide the strongest construct for DMUSO. Antegrade fixation may be preferred because it avoids violating the distal radioulnar joint capsule and articular surface of the ulna.

Abstract
BACKGROUND Predicting which patients will do well with arthroscopic triangular fibrocartilage complex (TFCC) debridement alone or which patients may benefit from arthroscopic debridement and ulnar shortening at the same time can be challenging. In this retrospective cohort study, we aimed to assess the rate and type of complications and reoperations after arthroscopic TFCC debridement. Furthermore, we aimed to identify factors associated with reoperation and specifically ulnar shortening osteotomy (USO) after this procedure. METHODS We included 163 patients who underwent arthroscopic TFCC debridement as a first surgery for treatment of their ulnar-sided wrist pain. Patient charts were manually reviewed, and ulnar variance was measured on preoperative posteroanterior radiographs of the wrist. Bivariate analysis and multivariable logistic regression analysis were performed to identify factors associated with reoperation. Additional subgroup analyses looking at USO after TFCC debridement were performed with Kaplan-Meier analysis and Cox regression survival analysis. RESULTS We found a complication rate of 14% and a reoperation rate of 19% (most common USO with 10%). Chondromalacia was independently associated with reoperation. Forty percent of patients with a positive ulnar variance later proceeded to USO. A hazard ratio of 1.8 per millimeter of ulnar variance was found. CONCLUSIONS Our data suggest that patients with a positive ulnar variance with frank chondral loss at the time of arthroscopic TFCC debridement may benefit from simultaneous USO.

Abstract
PURPOSE Characterizing the distal ulnar diaphyseal angle (DUDA) may be important for anatomic recreation of the distal ulna during ulnar shortening osteotomy procedures using conventional straight plates. This study characterized the DUDA and determined side-to-side, age, and sex effects on DUDA magnitudes and locations. METHODS Retrospective analyses of bilateral wrist radiographs were performed on 60 patients. The DUDA was defined as the angle of intersection between a line passing through the center of the distal ulnar metadiaphyseal region, in line with the landmarked long axis of the ulna, on a lateral radiograph. This inflection point was measured from the most distal aspect of the ulnar head and recorded as the DUDA tip-to-apex distance (TAD). Rater reliability was determined using the intraclass correlation coefficient. RESULTS We found DUDAs in 94% of radiographs. The mean DUDA angle was 5.6° ± 2.6° and the mean TAD was 45.3 ± 9.5 mm. The Pearson correlation coefficients for side-to-side comparisons were 0.47 for the DUDA angle and 0.69 for the TAD. For male and female patients, the mean DUDAs were 5.4° ± 2.3° and 5.9° ± 2.9°, respectively, and the mean TADs were 47.8 ± 9.7 mm and 41.7 ± 7.9 mm, respectively. The DUDA angle and TAD had negligible associations with age (r = -0.15 and -0.08, respectively). At 0.74 (95% CI, 0.58-0.85), interrater reliability was good. At 0.93 (95% CI, 0.88-0.96), intrarater reliability was excellent. CONCLUSIONS We demonstrated DUDAs, representing valgus deviations from the center axis and anteroposterior views of the ulna. Contralateral lateral wrist radiographs are moderate to strongly reliable in determining a DUDA. Rater reliability was good to excellent. CLINICAL RELEVANCE Re-creation of the DUDA may benefit procedures such as ulnar shortening osteotomy, fractures, or malunion by contributing to knowledge of distal radioulnar joint biomechanics.

Abstract
PURPOSE The primary aim of this study was to analyze the median time until patients performed their usual work following an ulnar shortening osteotomy (USO). The secondary aim was to identify factors influencing the median time until return to their usual work. METHODS We used a retrospective cohort of patients with ongoing data collection from our institution in the Netherlands. Patients with paid employment who underwent USO were invited to complete a return-to-work questionnaire at 6 weeks, 3 months, 6 months, and 12 months after surgery. The probability of and median time until return to usual work were assessed using an inverted Kaplan-Meier analysis. Factors influencing the return to usual work were evaluated using multivariable Cox proportional hazard regression. RESULTS In total, 111 patients who underwent USO were included, with a mean age of 46 years. The probability of returning to usual work in the first year was 92%, and the median time was 12 weeks. The type of work was independently associated with a return to work, with median times of 8, 12, and 14 weeks for light, moderate, and heavy physical work, respectively. We did not find differences in return to usual work based on age, sex, duration of complaints until surgery, treatment side, smoking status, the preoperative Patient-Rated Wrist Evaluation score, or whether the osteotomy was performed freehand or with an external cutting device. CONCLUSIONS Half of the patients that underwent USO fully performed their usual work by 12 weeks following surgery. We found that 92% of the patients performed their usual work within 1 year after surgery. We found a large variation in the time until a return to work based on the type of work. Surgeons can use this data to inform patients on the rehabilitation phase after USO. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
Background Recent advances in the understanding of ulnar-sided wrist pathologies such as ulnar abutment syndrome (UAS) have brought increased attention to the anatomy of the distal radioulnar joint (DRUJ). Previous work established three anatomical variants of the sigmoid notch (parallel, oblique, and reverse oblique). The reverse oblique DRUJ poses theoretical risk of increased contact forces following ulnar shortening osteotomy, a common method of treating UAS. Purpose As prevalence of reverse oblique morphology has been under-reported, this study aims to better define the prevalence of reverse oblique morphology in the adult population. Methods Institutional Review Board-approved review of 1,000 radiographs over a 2-year period was performed. Demographic data and radiographic measurements were recorded (ulnar variance, notch inclination, and presence of arthritis). Correlation tests, a test of proportions, a t -test, and linear and logic regression tests were used to examine associations between ulnar variance, sigmoid inclination, sex, age, and presence of arthritis. Results One thousand radiographs were analyzed revealing prevalence rates of: parallel-68%, oblique-26%, and reverse oblique-6%. Females were significantly more likely to have reverse inclination. No significant correlation was noted for morphology by age. Ulna positive variance was negatively correlated with reverse inclination. DRUJ arthritis was noted in 14% of patients. Higher sigmoid inclination was associated with higher odds of presence of arthritis, adjusting for sex and age. Higher incidence of arthritis was noted among patients with the oblique (20.8%) or reverse oblique (24.6%) compared with parallel (10.5%) morphology. Conclusion This series of 1,000 radiographs demonstrates a 6% overall prevalence of reverse obliquity. This large dataset allows for better quantification of the prevalence of DRUJ morphologies and determination of correlations that have clinical implications for patients with ulnar-sided wrist pathology. Level of Evidence This is a Level IV study.

Abstract
Entrapment of the extensor indicis proprius (EIP) after open reduction and internal fixation (ORIF) of the distal ulna with a plate and screw construct is rare. By literature review, we found evidence of such complication associated with distal radius fracture, but no past reports relating to the distal ulna. ORIF of the distal ulna is a common procedure for both fracture treatment and deformity correction. Due to the EIP muscle originating primarily from the dorsoradial surface of the distal ulna and the adjacent interosseous membrane, the muscle may be damaged or compressed by a fixation plate during ORIF, resulting in entrapment. We present two case reports of this rare complication, describing the method of clinical diagnosis, surgical treatment, and outcome. Our accompanying cadaver dissection provides an explanation for proper plate positioning during ORIF of the ulna to reduce the risk of EIP entrapment.

Background The purpose of this study is to characterize patient- and surgery-specific factors associated with perioperative pain level in patients undergoing ulnar shortening osteotomy (USO) for ulnar impaction syndrome (UIS). We hypothesize that preoperative opiate consumption, tobacco utilization, and severity of ulnar variance will be associated with less postoperative pain relief. Methods All cases of USO between January 2010 and December 2016 for management of UIS were retrospectively reviewed. Patient demographics, smoking status, type of labor, and opioid utilization before surgery were recorded. Radiographic measurements for ulnar variance, radial tilt and inclination, as well as triangular fibrocartilage complex and distal radial-ulnar joint (DRUJ) morphology were assessed. Pre- and postoperative pain score were recorded. Regression analysis was performed to determine predictors of pain scores. Results A total of 69 patients were included for the final analysis with a mean age of 44 years (range 17-73 years). Seventeen patients reported use of daily opioid medications at the time of surgery (25%). Patients who used opioid analgesics daily, active laborers, smokers, and patients involved in worker compensation claims had significantly less pain relief after surgery. Patients with osteotomy performed at the metaphysis had significantly more pain relief than patients that had diaphyseal osteotomy. Regression analysis identified tobacco utilization and anatomic site of osteotomy as independent predictors of postoperative pain. Conclusion The results from this study identified smoking and location of osteotomy as independent predictors of postoperative pain relief. While smoking cessation is paramount to prevent delayed/nonunion it may also help improve pain relief following USO. The potential to achieve greater shortening with a metaphyseal osteotomy suggests that in addition to the mechanical unloading the carpus, pain relief after USO may also stem from tensioning the ulnar collateral ligaments of the wrist, the ECU subsheath, and the radioulnar ligaments. Level of Evidence This is a Level III, therapeutic study.

Abstract
Forty-four patients who had been diagnosed with ulnar impaction syndrome and who were scheduled to undergo ulnar shortening osteotomy were randomized into two groups, one treated by ulnar shortening osteotomy alone and the other treated by ulnar shortening osteotomy combined with arthroscopic debridement. The response to treatment, including the pain numeric rating scale in an ulnar provocation test and the Disability of the Arm, Shoulder and Hand score was assessed at 3 and 12 months after surgery. The mean pain and disability scores showed significant clinical improvement at the 12-month follow-up in both groups. The pain scores at 3 months of follow-up were significantly better in the ulnar shortening osteotomy with arthroscopic debridement group. However, no significant differences were observed between the two groups in the disability scores at 3 and 12 months, or in the pain scores at 12-month follow-up. We conclude that similar improvements in symptom severity and hand function occurred in the long term in patients both with and without concomitant arthroscopic debridement. This information regarding concomitant arthroscopy could be used in the informed consent discussion with patients scheduled for ulnar shortening osteotomy. Level of evidence: II.

Abstract
Background Ulnocarpal impaction (UCI) is a described cause of ulnar side wrist pain. Questions Does absolute ulnar variance (UV) or change in UV with grip affect patient-rated outcome scores (PROS) in patients with symptomatic UCI undergoing surgery? Does UV differ between symptomatic and contralateral wrists? Does arthroscopic grade of triangular fibrocartilaginous complex (TFCC) tears and lunotriquetral (LT) ligament tears influence PROS? Do PROS improve following ulnar shortening osteotomy (USO) or wafer procedures and does improvement depend on the amount of shortening or achievement of negative UV? Patients and Methods We analyzed information on patients undergoing USO or wafer procedures for UCI as recorded in a database of prospectively collected information on individuals with ulnar side wrist pain. This included (1) patient-rated wrist evaluation and QuickDASH scores on enrolment, 3 and 12 months postoperatively; (2) standardized bilateral posteroanterior (PA) wrist radiographs, including PA grip views of the symptomatic wrist; and (3) arthroscopic findings. Results Larger changes in UV between PA neutral and grip views prior to surgery were associated with smaller improvements in PROS, 12 months after surgery. Actual UV value before and after surgery did not affect PROS. There was no difference in UV between symptomatic and contralateral wrists. The presence of TFCC or LT ligament tears did not influence PROS. Mean PROS improved postoperatively. Conclusions Ulnar shortening procedures result in improvement in PROS in patients with UCI. Variation in UV with rotation and grip results in variable outcomes. Level of Evidence This is a Level II, cohort study.

Abstract
Background Ulnocarpal impaction occurs when there is excessive loading between the ulnar carpus and the distal ulna. Ulnar shortening osteotomies (USOs) decompress the ulnocarpal joint. Many studies have evaluated USO but none have considered the effect of early active mobilization on union rate. Questions Does early active mobilization affect rate of union following USO? Does early active mobilization affect rate of complications following USO? Patients and Methods We performed a retrospective review of 15 consecutive patients that underwent 16 USOs between 2011 and 2015. There were seven males and eight females. Median age at time of shortening osteotomy was 47 years (range: 11-63 years). The median time of the procedure was 62 minutes (range: 45-105 minutes) and the median change in ulnar variance was 5.5 mm (range: 0-10.5 mm). Six patients were initially immobilized in incomplete plaster casts postoperatively, while the remainder had only wool and crepe dressings. Early active mobilization commenced after the first postoperative visit at 12 days. Results There was a 100% union rate in our series and 12 patients were pain-free at final follow-up. However, three of the patients with the longest times to union were smokers. Additionally, some patients may have achieved union between follow-up clinic visits. Conclusion Early active mobilization after USO does not affect union rate. Prospective, randomized studies are required to investigate the effect of early active mobilization in light of factors known to increase time to union, such as smoking. Level of Evidence This is a Level IV, case series.

Abstract
Purpose The relationship between triangular fibrocartilage complex (TFCC) tear and ulnar impaction syndrome has not been fully understood. We hypothesized that a TFCC tear could change the ulnar variance, which may be the cause of ulnar impaction syndrome. Patients and Methods A total of 72 patients who underwent TFCC foveal repair between January 2011 and June 2016 were included in this retrospective study. Among them, 44 patients diagnosed with TFCC foveal tear with distal radioulnar joint instability and no ulnar impaction syndrome underwent TFCC foveal repair only (group A) and 28 patients diagnosed with TFCC foveal tear with ulnar impaction syndrome underwent TFCC foveal repair and ulnar shortening osteotomy simultaneously (group B). We measured their ulnar variances in preoperative, postoperative, and last follow-up plain radiography. We also compared them with the ulnar variance of the contralateral (uninjured) wrist. Postoperative clinical outcomes, such as range of motions of the wrist, the visual analog scale (VAS) for pain, grip strength, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, were assessed. Results Ulnar variance increased after TFCC tears compared with that on the uninjured side in both groups (group A: 0.98 vs. 0.52 mm, p = 0.013; group B: 2.71 vs. 2.13 mm, p = 0.001). Once the TFCC was repaired, ulnar variance decreased (group A: 0.98 to 0.01 mm, p < 0.01; group B: 2.71 to 0.64 mm, p < 0.01). However, it was increased on the last follow-up radiograph (group A: 0.01 to 0.81 mm, p < 0.01; group B: 0.64 to 1.05 mm, p = 0.004). There were no significant improvement of range of motion, except for pronation-supination motion ( p = 0.04). Mean grip strength increased from 56.8 to 70.8% of the contralateral unaffected hand at the last assessment ( p = 0.01). Mean VAS for pain decreased from 7.4 ± 2.5 preoperatively to 2.7 ± 2 postoperatively ( p = 0.001). The QuickDASH score significantly improved from 45 to 9 ( p = 0.001). Conclusion Ulnar variance may be changed after a TFCC tear. In our study, it decreased after TFCC foveal repair. However, as time went on, the ulnar variance increased again, which could be one of the causes of ulnar impaction syndrome and ulnar-sided wrist pain. Level of Evidence This is a therapeutic Level IV study.

Abstract
Aim This study aims to evaluate the long-term complications, results, and patient satisfaction rates of a dorsally approached ulnar shortening osteotomy for ulnar impaction syndrome. Methods A retrospective chart review of 20 patients was performed. Primary outcomes of interest were subjective, measured using the Patient-Rated Wrist Evaluation (PRWE) score, Disability of the Arm, Shoulder, and Hand (DASH) score, and the third questionnaire about patient satisfaction, composed by the authors. Secondary outcomes included hardware removal due to irritation and other complications. Results Mean postoperative functional score of PRWE was 28 (standard deviation [SD], 30) and DASH 20 (SD, 26), respectively. Fifteen patients were satisfied with the operation. Removal of hardware was noted in six patients. In one patient plate breakage occurred. Conclusion Similar postoperative functional scores and complications were seen in patients undergoing an ulnar shortening osteotomy with a dorsally placed plate for ulnar impaction syndrome, compared with other plate placement localizations. The incidence of plate removal is also comparable to previously described results. As the dorsally placed plate and freehand technique, are relatively easy, we feel that it has a place in the treatment of ulnar impaction syndrome. Level of Evidence Level IV, retrospective cohort study.

Abstract
Background The purpose of this study is to evaluate the results of patients with ulnar impaction syndrome treated with diaphyseal osteotomy using freehand technique and fixation with ulnar osteotomy compression plate placed on the ulnar surface of the ulna. Materials and Methods A retrospective chart review of patients with ulnar impaction syndrome between 2010 and 2014 identified 38 patients. The following clinical data were observed: patient age, sex, range of motion, grip strength, visual analog scale (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH) score, radiological assessment, and complications. The mean follow-up period is 30 months. Eleven patients were excluded from the study. Results Compared with the contralateral side, the 27 patients included in this study attained 93 to 96% of wrist and forearm motion and 81% of the grip strength. The average DASH score was 18 in a mean follow-up period of 30 months. Three patients required plate removal and one case showed nonunion and a further operation was needed. Two patients reported persistent ulnar-sided wrist pain. Conclusion We concluded that placing the ulnar osteotomy plate on the ulnar surface of the ulna is a quicker procedure, with less soft tissue dissection and irritation, and very high union rate.

Abstract
Background Arthroscopic debridement of the triangular fibrocartilage (TFC) is well accepted in patients with ulnar impaction syndrome with central TFC lesions. Treatment remains controversial, however, when there is no such lesion from radiocarpal view. Purpose This study assessed the clinical outcome of arthroscopic central TFC resection and debridement and secondary ulnar shortening in patients with ulnar impaction with central TFC lesion compared with patients without TFC lesion. Patients and Methods Thirty-two consecutive patients with ulnar impaction syndrome were arthroscopically treated, 16 of whom had a central lesion of the TFC that was debrided. In the 16 patients with no lesion from the radiocarpal view, the TFC was centrally resected and debrided to decompress the ulnocarpal joint. Persisting symptoms necessitated ulnar shortening in four patients in each group. Two patients underwent repeat arthroscopic TFC debridement. All patients were examined at 3, 6, and 12 months, and at final follow-up (mean: 1.7 years) following arthroscopy, respectively ulnar shortening or hardware removal. Results In both groups, pain, Krimmer, and DASH scores significantly improved. Improvements of DASH scores were significantly higher in patients without lesion at 12 months and at final follow-up. For other parameters, no significant difference was found between the two groups. Conclusion In both situations, with and without central TFC lesion, resection and debridement sufficiently reduced the ulnar-sided wrist pain and improved function in three out of four patients, and therefore qualified as the first-line treatment of ulnar impaction syndrome as arthroscopy is performed, anyway. Those patients who complained of persisting or recurrent ulnar-sided wrist pain finally benefitted from ulnar shortening osteotomy as the secondary procedure. Level of Evidence Therapeutic III, case-control study.

Abstract
BACKGROUND Distal radius malunions lead to functional deficits. This study compares isolated ulnar shortening osteotomy (USO) to distal radius osteotomy (DRO) for the treatment of ulnar impaction syndrome following distal radius malunion. METHODS We retrospectively reviewed 11 patients with extra-articular distal radius malunions treated for ulnar impaction with isolated USO. This group was compared to a 1:1 age- and sex-matched cohort treated with isolated DRO for the same indication. Pain visual analog scale (VAS), wrist motion, grip strength, radiographic parameters, and perioperative complications were analyzed. Mean follow-up was 14.8 months. RESULTS VAS scores improved. Wrist range of motion improved in both cohorts with the exception of radial deviation, pronation, and supination in the USO cohort, which decreased from a mean of 17°-16°, 67°-57°, and 54°-52°, respectively. There was no significant difference between groups in regard to change in pain or range of motion, with the exception of pronation and ulnar deviation. The mean tourniquet time was shorter in the USO group. The final ulnar variance was 1.8 mm negative in the USO group and 1.1 mm positive in the DRO group. There was 1 reoperation following USO for painful nonunion, while there were 2 reoperations following DRO for persistent ulnar impaction. CONCLUSIONS An improvement in range of motion, grip strength, and VAS with restoration of the radioulnar length relationship was observed in both cohorts. USO is a simpler procedure with a shorter tourniquet time that can be an attractive alternative to DRO for ulnar impaction syndrome after distal radius malunions.

Abstract
BACKGROUND This study evaluates the results of ulnar shortening using the ulna osteotomy locking plate system (UOL; I.T.S. GmbH, Graz, Austria) with special regard to the time-dependent recovery of subjective and objective outcome parameters and surgeons' experiences. METHODS Ulnar shortening using the UOL was performed on 11 patients (3 men, 8 women) with an average age of 47 ± 19.6 years. Range of motion (ROM) and grip strength were compared with the contralateral hand. Patient-rated outcomes were measured using a visual analogue scale (VAS) for pain and the Disability of the Arm, Shoulder and Hand (DASH) and the Patient Rated Wrist Evaluation (PRWE) survey for subjective outcomes. Ulnar variance and bony union were assessed using conventional wrist radiographs. The surgeons evaluated intraoperative handling through a standardized feedback form. RESULTS ROM improved and grip strength increased significantly between preoperative values and final follow-up. Flexion and supination improved significantly between weeks 8 and 12 and grip strength from week 8 onward. Patient-rated outcomes changed significantly with a final DASH score of 14.2 ± 12.4 and a PRWE score of 24.3 ± 17.0. Pain levels improved significantly with no pain at rest and a mean VAS of 0.8 ± 1.2 during activity. The average amount of shortening was 4.0 ± 1.9 mm with a final ulnar variance of 0.2 ± 1.8 mm. All osteotomies healed with 2 cases of delayed union. CONCLUSIONS In ulnar shortening with the UOL, wrist function recovered after an initial decrease from week 8 onward. Subjective outcome parameters showed early recovery and improved continuously over time.

Abstract
Background Ulnar shortening osteotomy (USO) is a well-established procedure for the treatment of ulnar impaction syndrome. Although uncommon, the procedure can be associated with complications including nonunion, malunion, and hardware irritation. Case Description We present a 56-year-old woman who developed extensor carpi ulnaris (ECU) tendon instability following an USO. Literature Review The etiology of such a complication can be multifactorial. Clinical Relevance The recurrence of ulnar pain following an USO should raise the suspicion of possible ECU instability within the differential diagnosis.

Abstract
PURPOSE To examine potential risk factors for the development of delayed or nonunion following elective ulnar shortening osteotomy using a dedicated osteotomy plating system. METHODS We performed a retrospective review of all patients who underwent elective ulnar shortening using the TriMed single osteotomy dynamic compression plating system by 1 of 2 fellowship-trained hand surgeons over a 5-year period. Demographic data and medical, surgical, and social histories were reviewed. Time to bony union was determined radiographically by a blinded reviewer. Bivariate statistical analysis was performed to examine the effect of explanatory variables on the time to union and the incidence of delayed or nonunion. Those variables associated with the development of delayed or nonunion were used in a multivariate logistic regression model. Complications, including the need for additional surgery, were also recorded. RESULTS Seventy-two ulnar shortening osteotomy procedures were performed in 69 patients. Delayed union, defined as ≥ 6 months to union, occurred in 8 of 72 cases (11%). Of 72 surgeries, 4 (6%) resulted in nonunions, all of which required additional surgery. Hardware removal was performed in 13 of 72 (18%) of the cases. Time to union was significantly increased in smokers (6 ± 3 months) versus nonsmokers (3 ± 1 months). On multivariable analysis, diabetics and active smokers demonstrated a significantly higher risk of developing delayed union or nonunion. Patient age, sex, body mass index, thyroid disease, worker's compensation status, alcohol use, and amount smoked daily did not have an effect on the time to union or the incidence of delayed or nonunion. CONCLUSIONS Despite the use of an osteotomy-specific plating system, smokers and diabetics were at significantly higher risk for both delayed union and nonunion following elective ulnar shortening osteotomy. Other known risk factors for suboptimal bony healing were not found to have a deleterious effect.

Abstract
PURPOSE To compare the results and complications of fixed-angle dorsal locking plate fixation for ulnar shortening osteotomy (USO) with the conventional technique of volar plating. METHODS We performed a retrospective review of 32 patients undergoing USO on 34 wrists and compared the outcomes of 16 consecutive cases with dorsal 2.4/2.7-mm fixed-angle plating and 18 consecutive cases with volar 3.5-mm plating. A minimum of 12 months' follow-up was used to assess outcomes. Primary outcomes were painful hardware and removal of symptomatic implants. Secondary outcomes were pain, Patient-Rated Wrist Evaluation, range of motion, time to union, grip strength, and complications. RESULTS There were no significant differences in Patient-Rated Wrist Evaluation, pain score, range of motion, or time to union. Relative grip strength compared with the contralateral upper extremity in the dorsal group was higher than the volar group. After adjusting for hand dominance, dorsal plating was significantly associated with higher relative grip strength. There were 2 complications in the dorsal group, including one case with painful hardware. This was significantly lower than in the volar group, which had 10 complications including 2 nonunions and 6 cases of hardware-related soft tissue irritation. CONCLUSIONS Both volar and dorsal plating techniques for USO yielded good functional outcomes. There was a higher incidence of painful hardware requiring removal of implants in the volar group. Based on these findings, we advocate dorsal plate position using a smaller fixed-angle plate for USO in ulnar impaction syndrome. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic III.

Abstract
PURPOSE To investigate functional and subjective outcome parameters after arthroscopic debridement of central articular disc lesions (Palmer type 2C) and to correlate these findings with ulna length. METHODS Fifty patients (15 men; 35 women; mean age, 47 y) with Palmer type 2C lesions underwent arthroscopic debridement. Nine of these patients (3 men; 6 women; mean static ulnar variance, 2.4 mm; SD, 0.5 mm) later underwent ulnar shortening osteotomy because of persistent pain and had a mean follow-up of 36 months. Mean follow-up was 38 months for patients with debridement only (mean static ulnar variance, 0.5 mm; SD, 1.2 mm). Examination parameters included range of motion, grip and pinch strengths, pain (visual analog scale), and functional outcome scores (Modified Mayo Wrist score [MMWS] and Disabilities of the Arm, Shoulder, and Hand [DASH] questionnaire). RESULTS Patients who had debridement only reached a DASH questionnaire score of 18 and an MMWS of 89 with significant pain reduction from 7.6 to 2.0 on the visual analog scale. Patients with additional ulnar shortening reached a DASH questionnaire score of 18 and an MMWS of 88, with significant pain reduction from 7.4 to 2.5. Neither surgical treatment compromised grip and pinch strength in comparison with the contralateral side. We identified 1.8 mm or more of positive ulnar variance as an indication for early ulnar shortening in the case of persistent ulnar-sided wrist pain after arthroscopic debridement. CONCLUSIONS Arthroscopic debridement was a sufficient and reliable treatment option for the majority of patients with Palmer type 2C lesions. Because reliable predictors of the necessity for ulnar shortening are lacking, we recommend arthroscopic debridement as a first-line treatment for all triangular fibrocartilage 2C lesions, and, in the presence of persistent ulnar-sided wrist pain, ulnar shortening osteotomy after an interval of 6 months. Ulnar shortening proved to be sufficient and safe for these patients. Patients with persistent ulnar-sided wrist pain after debridement who had preoperative static positive ulnar variance of 1.8 mm or more may be treated by ulnar shortening earlier in order to spare them prolonged symptoms.

Abstract
UNLABELLED Background Malunion is a common complication of distal radius fractures. Ulnar shortening osteotomy (USO) may be an effective treatment for distal radius malunion when appropriate indications are observed. Methods The use of USO for treatment of distal radius fracture malunion is described for older patients (typically patients >50 years) with dorsal or volar tilt less than 20 degrees and no carpal malalignment or intercarpal or distal radioulnar joint (DRUJ) arthritis. Description of Technique Preoperative radiographs are examined to ensure there are no contraindications to ulnar shortening osteotomy. The neutral posteroanterior (PA) radiograph is used to measure ulnar variance and to estimate the amount of ulnar shortening required. An ulnar, mid-sagittal incision is used and the dorsal sensory branch of the ulnar nerve is preserved. An USO-specific plating system with cutting jig is used to create parallel oblique osteotomies to facilitate shortening. Intraoperative fluoroscopy and clinical range of motion are checked to ensure adequate shortening and congruous reduction of the ulnar head within the sigmoid notch. Results Previous outcomes evaluation of USO has demonstrated improvement in functional activities, including average flexion-extension and pronosupination motions, and patient reported outcomes. Conclusion The concept and technique of USO are reviewed for the treatment of distal radius malunion when specific indications are observed. Careful attention to detail related to surgical indications and to surgical technique typically will improve range of motion, pain scores, and patient-reported outcomes and will reduce the inherent risks of the procedure, such as ulnar nonunion or the symptoms related to unrecognized joint arthritis.

Abstract
Background The purpose of ulnar shortening osteotomy is literally to shorten the ulna. It can tighten the triangular fibrocartilage complex (TFCC), ulnocarpal ligaments, and interosseous membrane. Nowadays, this method is used to treat ulnar-sided wrist pain, for which we have also started to use a treatment algorithm. The purpose of this study was to review the long-term and clinical results based on our algorithm. Materials and Methods We retrospectively reviewed 30 patients with ulnocarpal impaction syndrome after a minimum follow-up of 5 years (Group A) and then retrospectively evaluated 66 patients with recalcitrant ulnar wrist pain treated based on our algorithm (Group B). Description of Technique Ulnocarpal abutment was confirmed arthroscopically. The distal ulna was approached through a longitudinal incision between the extensor carpi ulnaris and flexor carpi ulnaris. We performed a transverse resection of the ulna fixed with a small locking compression plate. The contralateral side served as the reference for the length of shortening (mean, 2.4 mm; range, 1-5 mm). Disappearance of ulnar abutment was then confirmed again arthroscopically. Results (Group A) Most patients showed good long-term clinical results. About half of the patients showed a bony spur at the distal radioulnar joint (DRUJ), but the clinical results did not significantly correlate with presence of bony spurs. Radiological parameters wre not related to the presence of bony spurs. (Group B) Twenty-four of the 66 patients investigated prospectively underwent an ulnar shortening osteotomy, with all showing good clinical results at 18 months postoperatively. Conclusions Ulnar shortening osteotomy can change the load of the ulnar side of the wrist and appears useful for ulnar-sided wrist pain in the presence of ulnar impaction. Level of evidence IV.

Abstract
Background Ulnar impaction syndrome is a condition in which the ulna impacts on the ulnar carpus. This most commonly occurs when the ulna is longer than the radius, but it can also occur in wrists with ulnar neutral and ulnar negative variance. Materials and Methods In this paper we outline our surgical technique for ulnar shortening osteotomy. A previously published retrospective case series of 28 patients treated at our center is presented. Fifty consecutive patients who underwent ulnar shortening osteotomy (USO) for ulnar impaction syndrome were approached for study, and 28 consented to review. Mean preoperative ulnar variance was +2.3 mm, and mean postoperative ulnar variance was -0.8 mm. Mean follow-up time was 21.2 months (8 to 41 months) and ten of 28 were receiving workers' compensation. Mean preoperative pain score (visual analog scale; VAS) was 7.9. Univariate analysis was performed to assess clinical and demographic data. In addition, subgroup analysis of workers' compensation patients and smokers was performed. Description of Technique A longitudinal incision over the subcutaneous border of the ulna is used to expose the ulna between the distal and middle third of the ulna from the ulna styloid. Preoperative posteroanterior (PA) X-rays are reviewed to determine the amount of shortening required, with a goal of creating -2 mm variance postoperatively. A 6-hole dynamic compression plate is predrilled distally prior to performing two oblique osteotomies separated by the desired shortening length. The fragments are reduced, controlling for rotation, and plated using compression. In some cases, a lag screw is employed across the oblique osteotomy site. Results Mean pain scores were significantly reduced postoperatively (VAS 7.9 versus 3.1, P < 0.0001). The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score was 37.2 postoperatively. Flexion, extension, and supination were reduced compared with the contralateral unaffected extremity (84.6%, 85.3%, and 86.9% of normal). Patients receiving workers' compensation and smokers had significantly more pain postoperatively (VAS 5.2 vs. 2.0, P = 0.0002 and VAS 4.4 vs 2.4, P < 0.05, respectively). Eleven of 28 patients required hardware removal for plate irritation, and five of 28 patients had a nonunion. Conclusion We present our surgical technique for ulnar shortening osteotomy. Pain was significantly improved in our population; however, patients receiving workers' compensation and smokers had less improvement in pain and higher disability scores.

Abstract
One of the challenges of forearm-level hand transplantation surgery is the achievement of osseous union of the ulna given the substantial soft tissue dissection, the use of immune modulating medications, and the diaphyseal level of osseous coaptation. Modification of the conventional surgical technique for an elective ulnar shortening osteotomy provides the advantages of precise osteotomy alignment, a large contact surface oblique osteotomy, and lag screw and compression plating technique. A step-by-step description of the developed modification is provided with a case example.

Abstract
PURPOSE To evaluate the outcomes of patients with ulnar impaction syndrome treated with a jig-facilitated, oblique, diaphyseal ulnar shortening osteotomy and fixed with a TriMed (Santa Clarita, CA) ulnar osteotomy compression plate. METHODS A retrospective chart review of patients with ulnar impaction syndrome identified 38 patients who had had ulnar shortening osteotomy and fixation with the TriMed dynamic compression system. The following clinical data were obtained: patient age, sex, follow-up range of motion, grip strength, and complications. After a minimum of 2 years after surgery, patients reported complications and completed a Disabilities of the Arm, Shoulder, and Hand questionnaire. RESULTS Eight patients were lost to follow-up. Compared to the opposite limb at an average of 8 months after surgery, the remaining 30 patients attained 92% to 97% of wrist and forearm motion and 71% of grip strength. The average Disabilities of the Arm, Shoulder, and Hand score was 12 after a minimum of 2 years after surgery. Four patients required plate removal due to irritation. Two patients reported persistent ulnar-sided pain, and 2 other patients developed atrophic nonunions and required autologous bone grafting. There were no infections. CONCLUSIONS Ulnar shortening osteotomy using the TriMed system yielded good clinical outcomes that are comparable to those previously documented using other systems.

Abstract
PURPOSE To evaluate outcomes in a single-surgeon series of ulnar shortening osteotomy for the treatment of traumatic isolated tears to the lunotriquetral interosseous ligament (LTIL). METHODS This study includes 53 consecutive cases of posttraumatic isolated LTIL tears treated with ulnar shortening osteotomy with minimum 1-year follow-up (range, 1.0-10.6 y). We confirmed all LTIL tears via arthroscopy before performing a precision 2.5-mm oblique osteotomy using a modified Rayhack technique. We assessed outcomes using grip strength measurements and Chun and Palmer's modified Gartland Werley wrist scoring system, which includes subjective and objective outcome measures. RESULTS Preoperatively, 45 cases were graded as fair (28%; n = 15) or poor (57%; n = 30) on the modified Gartland Werley score. There were insufficient data to calculate grades in 8 cases (15%). At final follow-up, most patients exhibited excellent (51%; n = 27) or good (32%; n = 17) scores, some scored fair (17%; n = 9), and none scored as poor. All subjective and objective variables significantly improved over a mean follow-up of 36 months (range, 12-127 mo). Mean grip strength increased from a value of 23 kg before surgery to 33 kg over the same period, a 41% increase. All patients achieved clinical and radiographic union by 10 months. Osteotomy plates were removed routinely in most cases (89%; n = 47) at a mean of 17 months. CONCLUSIONS Ulnar shortening osteotomy reduced symptoms of posttraumatic isolated LTIL tears in this single-surgeon series. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Distal ulna fractures, especially styloid injuries, classically have not been repaired, and only recently have these injuries been considered important. Certain fracture patterns of the distal ulna contribute to distal radioulnar joint (DRUJ) incongruity and potential instability. Appropriate fixation of the distal ulna is frequently difficult for several reasons: (1) high incidence of osteoporois in the affected patient population, (2) proximity of the injury to articular surfaces, and (3) lack of a proper implant to treat these injuries. The 2.0-mm locking compression distal ulna plate (LC-DUP) is an anatomically contoured implant with a low profile and fixed angle that provides proper stability to treat injuries of the distal ulna. The plate was designed for the treatment of distal ulna fractures, but its success has led to an extension of its indications to be used in treating symptomatic basistyloid ulnar nonunions and in ulnar shortening osteotomy for ulnocarpal abutment syndrome. The authors' description of the techniques used for each indication as well as their perspectives in the treatment of distal ulna injuries are described in detail in this report.
