Abstract Purpose Corrective osteotomy of a malunited distal radius conventionally relies on 2D imaging techniques for alignment planning and evaluation. However, this approach results in suboptimal bone repositioning, which is associated with poor patient outcomes. In this case series, we evaluate the use of novel patient-specific plates (PSPs), which feature navigation and fixation of bone segments as preoperatively planned in 3D. Methods Ten participants with distal radius malunion underwent CT scans for preoperative alignment planning. Patient-specific guides and plates were designed, 3D-printed, and sterilized for use in corrective surgery of the distal radius. Pre- and postoperative results were compared in regard to clinical, functional, and radiographic outcomes. Results The application of a PSP was successful in 7 of the 10 cases. After treatment, the residual alignment error was reduced by approximately 50% compared with conventional treatment. The use of PSPs reduced pain significantly. Pre- and postoperative results were pooled and demonstrated significant correlations between: (1) pain and malpositioning, (2) the range of pro- and supination motion, the MHOQ score, the EQ-5D-5L score and dorsovolar angulation, and (3) MHOQ score and proximodistal translation. Conclusion The correlation between malalignment and MHOQ score, EQ-5D-5L score, pain, and range of motion shows that alignment should be restored as well as possible. Compared to the conventional approach, which relies on 2D imaging techniques, corrective osteotomy based on 3D preoperative planning and intraoperative fixation with a PSP has been shown to improve bone alignment and reduce pain.

Background Little information exists to guide decision-making with regard to distal radius fractures in the setting of ipsilateral hemiparesis or hemiplegia. Methods Patients who sustained a distal radius fracture in the setting of ipsilateral hemiparesis or hemiplegia secondary to brain injury were evaluated. Investigated variables included perioperative pain, preinjury House functional classification score, length of immobilization, radiographic outcome measurements, and time to union. Results There were 15 patients with distal radius fractures with a mean age of 65.9 years. The mean clinical and radiographic follow-up was 2.8 and 2.9 years, respectively. Wrists were placed into the nonoperative group (NOG, n = 10) and operative group (OG, n = 5). Pain significantly decreased at final follow-up for both groups. Baseline House functional classification scores averaged 1.3 and 1.6 for the NOG and OG, respectively, and were maintained at final follow-up. Length of immobilization for the NOG was 46 days and OG was 37 days, P = .15. Radiographic outcomes at final follow-up in the NOG and OG, respectively, were a mean radial height of 9.3 versus. 11.6 mm, radial inclination of 18.3° versus 22.3°, 4.2° dorsal tilt versus 5.3° volar tilt, and tear drop angle of 45.6° versus 44.5°. There were no significant differences in these measurements. Time to radiographic union averaged 58 days for the NOG and 67 days for the OG, P = .42. There were no revision surgeries. Conclusions Based on this small case series, patients with distal radius fracture and ipsilateral hemiparesis or hemiplegia may have similar clinical, functional, and radiographic outcomes, regardless of nonoperative or operative treatment.

Abstract Background Revision surgery after the Latarjet procedure is a rare and challenging surgical problem, and various bony or capsular procedures have been proposed. This systematic review examines clinical and radiographic outcomes of different procedures for treating persistent pain or recurrent instability after a Latarjet procedure. Methods A systematic review of the literature was performed using the Medline, Cochrane, EMBASE, Google Scholar and Ovid databases with the combined keywords “failed”, “failure”, “revision”, “Latarjet”, “shoulder stabilization” and “shoulder instability” to identify articles published in English that deal with failed Latarjet procedures. Results A total of 11 studies (five retrospective and six case series investigations), all published between 2008 and 2020, fulfilled our inclusion criteria. For the study, 253 patients (254 shoulders, 79.8% male) with a mean age of 29.6 years (range: 16–54 years) were reviewed at an average follow-up of 51.5 months (range: 24–208 months). Conclusions Eden–Hybinette and arthroscopic capsuloplasty are the most popular and safe procedures to treat recurrent instability after a failed Latarjet procedure, and yield reasonable clinical outcomes. A bone graft procedure and capsuloplasty were proposed but there was no clear consensus on their efficacy and indication.

Background:Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.Methods:Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.Results:Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.Conclusion:Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.Level of Evidence:Level IV, retrospective case series.

The Cost

Background: Patient-specific 3-D printing cutting blocks (PSI) have been used instead of traditional intramedullary cutting guides. We hypothesized that PSI would lead to significantly decreased operating room (OR) time and significant cost savings to our institution with noninferior radiographic outcomes and no difference in expected vs actual implant size when compared with standard referencing (SR). Methods: Patients who had undergone total ankle replacements at our institution from 2013 through 2016 were included in the study. Associations between demographic variables and postoperative alignment in the SR vs PSI group were calculated using the Wilcoxon rank-sum test and the intraclass correlation coefficient. The cost of the operation was calculated using both an institutionally based fixed cost of OR time and using Time Driven Activity Based Cost (TDABC) accounting. A total of 43 patients were included in the study, 13 in the SR group and 30 in the PSI group. Results: Operative time (168 vs 137 minutes) and tourniquet time (123 vs 113 minutes) were significantly lower in the PSI vs the SR group. PSI predictions were accurate 100% of the time for tibial components and 83% of the time for talar components. Average costs of TAA using PSI were significantly reduced by $7597.00 when using traditional OR accounting, whereas PSI was $836.00 more expensive on average using TDABC accounting. Conclusion: Further research is needed to determine the cost-effectiveness of PSI vs SR in TAA; however, it does appear to save time intraoperatively. The long-term effect on clinical outcomes requires further study. Level of Evidence: Level III, case-control study.

Background: Medial cuneiform dorsal opening wedge (Cotton) osteotomy is often used for treating forefoot varus in patients undergoing surgery for stage II posterior tibialis tendon dysfunction. The goal of this study was to examine the radiographic outcomes of Cotton osteotomy with bioactive glass wedge to assess for both maintenance of correction and clinical results and complications. We hypothesized that bioactive glass wedges would maintain correction of the osteotomy with low complication rates. Methods: Between December 2015 and June 2016, the charts of 17 patients (10 female and 7 male) who underwent Cotton osteotomy using bioactive glass wedges were retrospectively reviewed. Patient age averaged 56.8 years (range, 16-84). The average follow-up was 6.5 months. Radiographs were reviewed to assess for initial correction and maintenance of correction of medial column sag as well as for union. Charts were reviewed for complications. Results: The medial column sag correction averaged 15.6% on the final postoperative lateral radiograph. Meary angle averaged 19 degrees (3.14-42.8 degrees) preoperatively and 5.5 degrees (0.4-20.7 degrees) at final follow-up. All patients achieved clinical and radiographic union. One patient developed neuropathic midfoot pain and was managed with sympathetic blocks. One patient had a delayed union that healed at 6 months without surgical intervention. No patients required the use of custom orthotics or subsequent surgical procedures. Conclusion: Cotton osteotomy with bioactive glass wedges produced consistent correction of the medial column with low risk. Level of Evidence: Level IV, case series.

Background: In an effort to minimize narcotic analgesia and its potential side effects, anti-inflammatory agents offer great potential provided they do not interfere with bone healing. The safety of ketorolac administration after foot and ankle surgery has not been well defined in the current literature. The purpose of this study was to report clinical healing and radiographic outcomes for patients treated with a perioperative ketorolac regimen after open reduction and internal fixation (ORIF) of ankle fractures. Methods: A retrospective review was performed on all patients that received perioperative ketorolac at the time of lateral malleolar, bimalleolar, and trimalleolar ankle ORIF by a single surgeon between 2010 and 2016 with minimum 4 months follow-up. Patients received 20 tablets of 10 mg ketorolac Q6 hours. Radiographs were evaluated independently by 2 blinded fellowship-trained orthopedic foot and ankle surgeons to assess for radiographic healing. A total of 281 patients were included, with a median age of 51 years and 138 males (47%). Statistical analysis consisted of a linear mixed-effects regression. Results: In all, 265/281 (94%) were clinically healed within 12 weeks and 261/281 (92%) were radiographically healed within 12 weeks. Within the group of patients that did not heal within 12 weeks, mean time to clinical healing was 16.9 weeks (range = 14-25 weeks), and mean time to radiographic healing was 17.1 weeks (range = 14-25 weeks). In patients taking ketorolac, there were no cases of nonunion in our series (n = 281) and no significant difference found between fracture patterns and healing or complications ( P = .500). Conclusions: Perioperative ketorolac use was associated with a high rate of fracture union by 12 weeks. This is the first study to examine the effect of ketorolac on radiographic time to union of ankle fractures. Additional studies are necessary to determine whether ketorolac helps reduce opioid consumption and improve pain following ORIF of ankle fractures. Level of Evidence: Level IV, case series.

Abstract Background Distal radius fracture is one of the most common lesions in adults. Surgical techniques have evolved considerably with a clear tendency toward mini-invasive techniques. Objective Our aim is to push the limits to a 12 mm approach and evaluate its clinical and radiological results. Patients and Methods Ten fractures in nine patients were operated by a double incision with mean size 11.50 ± 3.41 mm (range 8.00–1.00) and using a specially designed volar distal locking plate. Results At the latest follow-up, visual analogue scale score for pain (0.20 ± 0.63 during rest and 0.60 ± 1.07 while making efforts) and quick DASH (quick Disabilities of the Arm, Shoulder and Hand) score (6.14 ± 7.43) were extremely low. All the range of motion parameters and grip strength were above the 95% barrier of the contralateral side, with exception of ulnar deviation. Radiological parameters obtained were located within the normal ranges. Time to return to independent daily tasks and work was 6.67 ± 5.15 and 10.14 ± 14.24 days, respectively. One case of transient carpal tunnel syndrome was solved with watchful waiting and one case of extensor tendons impingement was improved after plate removal. All patients were completely satisfied at the end of the treatment. Conclusion In conclusion, mini-invasive volar technique for distal radius fractures with special designed plates in carefully selected patients allowed us to obtain good clinical and radiological results, minimal complications, fast recovery, and high-satisfactory rates. Level of Evidence This is a Level IV, case series study.

Background. Syndesmotic disruption occurs in 20% of ankle fractures and requires anatomical reduction and stabilization to maximize outcomes. Although screw breakage is often asymptomatic, the breakage location can be unpredictable and result in painful bony erosion. The purpose of this investigation is to report early clinical and radiographic outcomes of patients who underwent syndesmotic fixation using a novel metal screw designed with a controlled break point. Methods. We performed a retrospective review of all patients who underwent syndesmotic fixation utilizing the R3lease Tissue Stabilization System (Paragon 28, Denver, CO) over a 12-month period. Demographic and screw-specific data were obtained. Postoperative radiographs were reviewed, and radiographic parameters were measured. Screw loosening or breakage was documented. Results. 18 patients (24 screws) met inclusion criteria. The mean follow-up was 11.7 months (range = 6.0-14.7 months). 5/24 screws (21%) fractured at the break point. No screw fractured at another location, nor did any fracture prior to resumption of weight bearing; 19 screws did not fracture, with 8/19 intact screws (42.1%) demonstrating loosening. There was no evidence of syndesmotic diastasis or mortise malalignment on final follow-up. No screws required removal during the study period. Conclusion. This study provides the first clinical data on a novel screw introduced specifically for syndesmotic fixation. At short-term follow up, there were no complications and the R3lease screw provided adequate fixation to allow healing and prevent diastasis. Although initial results are favorable, longer-term follow-up with data on cost comparisons and rates of hardware removal are needed to determine cost-effectiveness relative to similar implants.

Abstract Background Closed reduction and cast immobilization of displaced distal radius fractures carries the risk of secondary displacement, which could result in a symptomatic malunion. In patients with a symptomatic malunion, a corrective osteotomy can be performed to improve pain and functional impairment of the wrist joint. Objective The aim of this study was to assess the functional outcomes of children who underwent a corrective osteotomy due to a symptomatic malunion of the distal radius. Methods Between 2009 and 2016, all consecutive corrective osteotomies of the distal radius of patients younger than 18 years were reviewed. The primary outcome was functional outcome assessed with the ABILHAND-Kids score. Secondary outcomes were QuickDASH (Quick Disabilities of Arm, Shoulder, and Hand) score, range of motion, complications, and radiological outcomes. Results A total of 13 patients with a median age of 13 years (interquartile range [IQR]: 12.5–16) were included. The median time to follow-up was 31 months (IQR: 26–51). The median ABILHAND-Kids score was 42 (range: 37–42), and the median QuickDASH was 0 (range: 0–39). Range of motion did not differ significantly between the injured and the uninjured sides for all parameters. One patient had a nonunion requiring additional operative treatment. The postoperative radiological parameters showed an improvement of radial inclination, radial height, ulnar variance, dorsal tilt, and dorsal tilt. Conclusion Corrective osteotomy for children is an effective method for treating symptomatic malunions of the distal radius. Level of Evidence This is a Level IV study.
