RESUMEN
BACKGROUND: Recent guidelines recommend non-operative treatment as primary treatment in elderly patients with displaced distal radius fractures. Most of these fractures are closely reduced. We aimed to evaluate the radiological results of closed reduction and casting of dorsally displaced distal radius fractures in patients 65 years or older. METHODS: A total of 290 patients treated during the years 2015, 2018 and 2019 in an urban outpatient fracture clinic with complete follow-up at least 5 weeks post-reduction were available for analysis. Closed fracture reduction was performed by manual traction under hematoma block. A circular plaster of Paris cast was used. Radiographs pre- and post-reduction and at final follow-up were analyzed. RESULTS: Mean age was 77 years (SD 8) and 258 (89%) were women. Dorsal tilt improved from mean 111° (range 83-139) to 89° (71-116) post-reduction and fell back to mean 98° (range 64-131) at final follow-up. Ulnar variance was 2 mm ((-1)-12) pre-reduction, 0 mm ((-3)-5) post-reduction and ended at mean 2 mm (0-8). Radial inclination went from 17° ((-6)-30) to 23° (SD 7-33), and then back to 18° (0-32) at final follow-up. 41 (14%) patients had worse alignment at final follow-up compared to pre-reduction. 48 (17%) obtained a position similar to the starting point, while 201 (69%) improved. Fractures with the volar cortex aligned after reduction retained 0.4 mm (95% Confidence Interval (CI) 0.1 to 0.7; p = 0,022) more radius length during immobilization. In a regression analysis, less ulnar variance in initial radiographs (OR 1.8 (95% CI 1.4 to 2.3) per mm, p < 0.001) and lower age (OR 1.06 (95% CI 1.02 to 1.09) per year, p < 0.003) protected against loss of reduction. CONCLUSION: Subsequent loss of reduction after initial closed reduction was seen in most distal radius fractures. Reduction improved overall alignment in 2/3 of the patients at final follow-up. An aligned volar cortex seemed to protect partially against loss of radial length.

Objectives: The aim of this study was to evaluate functional and radiographic results after open reduction and internal fixation of distal humeral fractures using precontoured locking plates. Our main hypothesis was that patients older than 65 years have inferior outcomes compared with younger patients. Methods: All patients treated for a distal humeral fracture with precontoured locking plates between 2006 and 2017 at a level 1 trauma center were identified. Included patients underwent a clinical examination, and new radiographs were obtained. Functional outcomes were evaluated using Quick Disability of the Arm, Shoulder and Hand, Mayo Elbow Performance Score, visual analog scale elbow satisfaction, and range of motion. Complications and reoperations were recorded. Results: Fifty-seven patients with a median age of 60 years were included in this study. Median Quick Disability of the Arm, Shoulder and Hand was 14, and median Mayo Elbow Performance Score was 85. There was no difference in functional scores in patients younger than 65 years or 65 years or older. However, the median flexion-extension arc was 121 degrees in patients younger than 65 years and 111 degrees in patients 65 years or older (P = 0.01). The overall complication rate was 68%, and 24 patients had at least 1 reoperation. Ulnar neuropathy was the most common complication followed by reduced range of motion. Conclusions: Operative management of distal humeral fractures with precontoured locking plates provides good functional outcome. The patient-reported outcomes were good, independent of patient age. The implant failure rate is low with precontoured locking plates; however, the complication rate remains high, and reoperations are common. Level of Evidence: Level 4, retrospective study.
RESUMEN
BACKGROUND: Tension band wiring (TBW) is the standard method for treating transverse olecranon fractures, but high rates of complications and reoperations have been reported. Plate fixation (PF) with locking screws has been introduced as an alternative method that may retain the fracture reduction better with a higher load to failure. METHODS: Twenty paired cadaveric elbows were used. All soft tissues except for the triceps tendon were removed. A standardized transverse fracture was created, and each pair was allocated randomly to TBW or PF with locking screws. The triceps tendon was mounted to the materials testing machine with the elbow in 90° of flexion. Construct stiffness was compared 3 times. Then, the elbows underwent a chair lift-off test by loading the triceps tendon to 300 N for 500 cycles. Finally, a load-to-failure test was performed, and failure mechanism was recorded. RESULTS: The construct stiffness of PF was higher in the first of 3 measurements. No difference was observed in the cyclic test or in load to failure. Hardware failure was the failure mechanism in 8 of 10 TBW constructs, and all failures occurred directly under the twists of the metal wire. Hardware failure was the cause of failure in only 1 elbow in the PF group (P < .01). CONCLUSION: There was no difference in fracture displacement following fixation with TBW and PF with locking screws in transverse olecranon fractures. However, assessment of the mode of hardware failure identified the metal cerclage twist as the weakest link in the TBW construct.

PURPOSE: The importance of an intact lacertus fibrosus in distal biceps tendon injury is uncertain. This study aimed to assess long-term outcome following distal biceps tendon repair with focus on the significance of the lacertus fibrosus. METHODS: Thirty-six patients surgically treated for primary distal biceps tendon rupture were identified. Medical records were reviewed for patient demographics in addition to surgery-related data. All patients underwent a targeted clinical examination to assess elbow function and they completed a patient reported questionnaire. Radiographs were obtained at time of follow-up and evaluated for the presence of osteoarthritis (OA) and heterotopic ossification (HO). RESULTS: All patients were male. Median age at injury was 48 years (34-69) and median time of follow-up of was 71 months (23-165). All patients presented functional range of motion in the elbow. Median flexion strength was 76 Nm (45-135) (median 99% of uninjured side; range 66-128) with intact lacertus fibrosus and 70 Nm (43-124) (88%, 62-114) with torn lacertus fibrosus. Median supination strength was 6 Nm (3-11) (86%, range 36-144) with intact lacertus fibrosus and 8 Nm (3-17) (67%, 28-118) with torn lacertus fibrosus. No signs of OA were revealed, but three patients had major HO of which one patient had minor limitations in range of elbow motion. CONCLUSION: An intact lacertus fibrosus contributes to elbow strength and should be preserved in distal biceps tendon repair. LEVEL OF EVIDENCE: III.

BACKGROUND: Injuries in the musculoskeletal system, such as tendon and ligament ruptures, are challenging to manage and often require surgical reconstructions with limited long-term success. Thus, characterizations of these tissues are urgently needed to better understand cellular mechanisms that regulate tissue homeostasis and healing. Explant culturing systems allow for ex vivo analysis of tissues in an environment that mimics the native microenvironment in vivo. METHODS: Collaborative efforts within our institution facilitated the establishment of a novel explant culturing system. Tissue specimens cultured in single wells, with individual applied loading and/or biological environment, allowed characterization of tissue cultured under a variety of biological loading conditions. Quantitative PCR analysis for selected gene markers was our primary outcome. RESULTS: Data were stratified for analysis by either culture environment or loading condition. Our gene expression results show that specimens clustered by culture condition may differ in molecular markers related to ECM production (e.g., Col1a1, Adamts4) and/or organization (e.g., Tnc, Dnc). In contrast, loading condition did significantly alter the median gene expression levels of tissues in comparison to unloaded control samples, although gene expression values related to ECM degradation (e.g., Mmp1, Mmp10) were altered in tendons cultured under tension in the device. CONCLUSION: Our study demonstrates promising utility of a novel explant culturing system for further characterization of musculoskeletal tissues such as native tendons and ligaments, as well as pathologic fibrotic tissues resulting from arthrofibrosis or Dupuytren's disease.

AIMS: Options for the treatment of intra-articular ligament injuries are limited, and insufficient ligament reconstruction can cause painful joint instability, loss of function, and progressive development of degenerative arthritis. This study aimed to assess the capability of a biologically enhanced matrix material for ligament reconstruction to withstand tensile forces within the joint and enhance ligament regeneration needed to regain joint function. MATERIALS AND METHODS: A total of 18 New Zealand rabbits underwent bilateral anterior cruciate ligament reconstruction by autograft, FiberTape, or FiberTape-augmented autograft. Primary outcomes were biomechanical assessment (n = 17), microCT (µCT) assessment (n = 12), histological evaluation (n = 12), and quantitative polymerase chain reaction (qPCR) analysis (n = 6). RESULTS: At eight weeks, FiberTape alone or FiberTape-augmented autograft demonstrated increased biomechanical stability compared with autograft regarding ultimate load to failure (p = 0.035), elongation (p = 0.006), and energy absorption (p = 0.022). FiberTape-grafted samples also demonstrated increased bone mineral density in the bone tunnel (p = 0.039). Histological evaluation showed integration of all grafts in the bone tunnels by new bone formation, and limited signs of inflammation overall. A lack of prolonged inflammation in all samples was confirmed by quantification of inflammation biomarkers. However, no regeneration of ligament-like tissue was observed along the suture tape materials. Except for one autograft failure, no adverse events were detected. CONCLUSION: Our results indicate that FiberTape increases the biomechanical performance of intra-articular ligament reconstructions in a verified rabbit model at eight weeks. Within this period, FiberTape did not adversely affect bone tunnel healing or invoke a prolonged elevation in inflammation. Cite this article: Bone Joint J 2019;101-B:1238-1247.

Objective The objective of this article is to evaluate the outcomes and complication rate for Adams-Berger anatomic reconstruction of the distal radioulnar joint (DRUJ), in addition, to determine the role of sigmoid notch anatomy on failure. Methods We conducted a retrospective chart review to evaluate adult patients that had undergone reconstruction of the DRUJ for instability with the Adams-Berger procedure between 1998 and 2015 within our institution with > 24 months follow-up. Charts were reviewed for patient demographics, mechanism of injury, outcome, and complications. Results Ninety-five wrists in 93 patients were included. Mean age at surgery was 37.3 years with 65.2 months follow-up. At the last follow-up, 90.8% had a stable DRUJ, 5.3% did not, and 3.4% had some laxity. Postoperatively, 75.9% described either no pain or mild pain. Grip strength increased while pronosupination decreased. Procedure success was 86.3%, as 12 patients underwent revision at 13.3 months postoperatively. Reconstructive failure was more common in females when an interference screw was utilized for tendon fixation. Age, timing of surgery, type of graft, sigmoid notch anatomy, and previous surgery did not affect revision or failure rate. Conclusion Our findings demonstrate that Adams-Berger reconstruction of the DRUJ provides reliable long-term results with an overall success of 86% at > 5 years follow-up. Level of evidence/Type of study This is a Level IV, therapeutic study.
RESUMEN
Background and purpose - Outcome after ligament reconstruction or tendon repair depends on secure tendon-to-bone healing. Increased osteoclastic activity resulting in local bone loss may contribute to delayed healing of the tendon-bone interface. The objective of this study was to evaluate the effect of the bisphosphonate zoledronic acid (ZA) on tendon-to-bone healing. Methods - Wistar rats (n = 92) had their right Achilles tendon cut proximally, pulled through a bone tunnel in the distal tibia and sutured anteriorly. After 1 week animals were randomized to receive a single dose of ZA (0.1 mg/kg IV) or control. Healing was evaluated at 3 and 6 weeks by mechanical testing, dual-energy X-ray absorptiometry and histology including immunohistochemical staining of osteoclasts. Results - ZA treatment resulted in 19% (95% CI 5-33%) lower pullout strength and 43% (95% CI 14-72%) lower stiffness of the tendon-bone interface, compared with control (2-way ANOVA; p = 0.009, p = 0.007). Administration of ZA did not affect bone mineral density (BMD) or bone mineral content (BMC). Histological analyses did not reveal differences in callus formation or osteoclasts between the study groups. Interpretation - ZA reduced pullout strength and stiffness of the tendon-bone interface. The study does not provide support for ZA as adjuvant treatment in tendon-to-bone healing.

Tendon graft healing in bone tunnels for the fixation of intra-articular ligament reconstructions may limit clinical outcome by delaying healing. This study assesses the effects of hydrogel-mediated delivery of bone anabolic growth factors in a validated model of tendon-to-bone tunnel healing. Forty-five Wistar rats were randomly allocated into three groups (BMP2-treated, GSK126-treated, and placebo). All animals underwent a tendon-to-bone tunnel reconstruction. Healing was evaluated at 4 weeks by biomechanical assessment, micro-computed tomography (bone mineral density, bone volume, cross sectional area of bone tunnels), and traditional histology. Adverse events associated with the hydrogel-mediated delivery of drugs were not observed. Results of our biomechanical assessment demonstrated favorable trends in animals treated with bone anabolic factors for energy absorption (P = 0.116) and elongation (P = 0.054), while results for force to failure (P = 0.691) and stiffness (P = 0.404) did not show discernible differences. Cross sectional areas for BMP2-treated animals were reduced, but neither BMP2 nor GSK126 administration altered bone mineral density (P = 0.492) or bone volume in the bone tunnel. These results suggest a novel and positive effect of bone anabolic factors on tendon-to-bone tunnel healing. Histological evaluation confirmed absence of collagen fibers crossing the soft tissue-bone interface indicating immature graft integration as expected at this time point. Our study indicates that hydrogel-mediated delivery of BMP2 and GSK126 appears to be safe and has the potential to enhance tendon-to-bone tunnel healing in ligament reconstructions.

BACKGROUND: Multiple enchodromatosis of bone, termed Ollier's disease, or Maffucci syndrome when associated with hemangiomas, is a rare disease that can affect the pediatric hand. This condition often causes a finger mass, deformity, pain and possible pathologic fractures, and has been associated with malignant transformation to chondrosarcoma. The aim of our study is to describe the long-term sequela of multiple enchondromatosis of the hand in the pediatric population, specifically the rates of malignant transformation, tumor recurrence, rates of pathologic fracture, and phalangeal growth arrest. METHODS: We examined 15 pediatric patients who were treated in our institute with a total of 127 phalanges and metacarpals lesions. Only patients with follow-up of at least 4 years were included. We retrospectively reviewed patients' chart and hand radiograph for symptoms including pathologic fractures, indications for surgery, and postoperative complications including tumor recurrence, and malignant transformation. We assessed phalangeal growth arrest with radiographs and normalized phalangeal growth charts. RESULTS: Mean age of diagnosis was 5.8 years and mean follow-up time was 15.4 years. Pathologic fractures were common at 46% of pediatric patients, but ceased to occur once reaching adulthood. Outcomes of pathologic fractures were excellent, regardless of treatment. Malignant transformation occurred in 1 patient and did not occur during childhood. A total of 80% of patients and 29% of lesions underwent surgical treatment of curettage and bone graft for the lesion, yet recurrence was common and affected 33% of treated patients. Phalangeal growth arrest was the most common long-term sequela and affected 11% of phalanxes and metacarpals. This sequela was significantly more prevalent in patients who had surgical excision of the tumor. CONCLUSIONS: Our findings reassure that malignant transformation of enchodromatosis of the hand is unlikely in the pediatric population. Pathologic fracture is common, but has excellent outcomes. When considering surgery, parents should be counseled about the possibility of phalangeal growth arrest and recurrence of the lesion. TYPE OF STUDY/LEVEL OF EVIDENCE: Level IV-therapeutic.

BACKGROUND: This study assesses long-term functional and subjective outcomes following arthroscopic assisted resection of lesions of the triangular fibrocartilage complex (TFCC). METHODS: Functional and subjective outcomes were assessed based on review of patient charts for patient demographic characteristics, comprehensive clinical evaluation, obtained radiographs, and patient-reported questionnaires. RESULTS: Fifteen patients, of whom 9 were female, and 10 dominant wrists, were included in this study. Median age was 60 (range, 37-73) years, and median duration of follow-up was 19 (range, 18-21) years. Median Mayo Wrist Score was 85 (range, 45-100). Four patients scored excellent, 7 good, 3 fair, and 1 poor result according to the Modified Mayo Wrist Score. Median Quick Disabilities of the Arm, Shoulder and Arm was 20 (range, 0-45) and Patient-Rated Wrist and Hand Evaluation was 8 (range, 0-61). Patients reported high rate for satisfaction and low rate for pain. All patients presented intact stability of the distal radioulnar joint. CONCLUSIONS: This study demonstrates persisting satisfactory subjective and functional outcomes for patients following arthroscopic assisted resection for lesions of the TFCC at 19 years of follow-up. Arthroscopically assisted resection of selected TFCC lesions seems to be both a safe and efficient procedure.

Patients suffering from ulnar-sided wrist pain after trauma may develop tenderness, clicking, a positive fovea sign, or instability of the distal radioulnar joint. If the pain is persistent, conservative treatment does not help, and the patient agrees to surgery, arthroscopy may reveal a triangular fibrocartilage complex (TFCC) injury with capsular detachment, foveal avulsion, or a combination thereof. Capsular reattachment is possible using an arthroscopic assisted technique. The reattachment can be performed with an inside-out, outside-in, or all-inside technique, providing good to excellent results, which tend to persist over time, in 60% to 90% of cases.

OBJECTIVE: The present study aimed to assess long-term functional outcome for patients after arthroscopic assisted suture for peripheral tears of the triangular fibrocartilage complex (TFCC). METHODS: Eleven patients, 26 (15-59) years old at time of surgery, 48 (35-78) years old at time of follow-up, were available for this 20-year follow-up. Subjective and objective outcomes, such as range of motion, grip strength, patients' satisfaction, pain, and Mayo Modified Wrist Score, were assessed, as well as asking the question if the patients would have had the surgery done again, knowing the outcome, based on a clinical examination and patient reported questionnaires. RESULTS: Median Mayo Wrist score was 85 (30-100) and, according to the Modified Mayo Wrist Score, seven patients presented good or excellent results. The patients reported median low 25 (0-66) on pain and median high 90 (1-100) on satisfaction. Ten patients presented with intact stability of the distal radioulnar joint at follow-up. Compared to the level of pain prior to surgery, two patients reported to be free of pain, five patients experienced major pain relief, two patients reported minor pain relief, while two patients reported no difference. CONCLUSIONS: The findings of the present study support the trend of persisting good results for the majority of patients having undergone arthroscopically assisted repair with an outside-in suture technique for peripheral tears of the TFCC.

BACKGROUND: The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) to patients undergoing anterior cruciate ligament reconstruction (ACLR) is controversial because it may impair tissue healing and clinical outcomes. PURPOSE: To assess the effect of NSAID administration on patients undergoing ACLR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Included patients were aged >15 years and were registered in the Norwegian Knee Ligament Registry from 2008 until 2013 after the primary ACLR. Patients with insufficient data regarding administration of NSAIDs and those with associated knee ligament injuries requiring surgical treatment were excluded from this study. Graft survival was estimated using Kaplan-Meier survival curves, and hazard ratios (HRs) for revision were evaluated using Cox regression analysis. Logistic regression analysis was used to calculate the odds ratio (OR) for a Knee Injury and Osteoarthritis Outcome Score (KOOS)-quality of life (QOL) subscale score <44 at 2-year follow-up. RESULTS: A total of 7822 patients were included in the analysis for graft survival and assessment for risk of revision. Of these, 4144 patients were administered NSAIDs postoperatively. The mean duration of follow-up was 2.8 years (range, 0-5.9 years). Administration of NSAIDs did not influence graft survival (P = .568). Adjusted Cox regression analyses demonstrated the same finding regarding risk of revision (HR, 1.0; 95% CI, 0.8-1.3). ACLR using a bone-patellar tendon-bone autograft showed a reduced risk of revision (HR, 0.3; 95% CI, 0.1-0.8) among patients administered NSAIDs. In subgroup analyses of 3144 patients, administration of NSAIDs demonstrated a beneficial effect on the risk of a KOOS-QOL score <44 at 2-year follow-up (OR, 0.8; 95% CI, 0.6-0.9). CONCLUSION: Administration of NSAIDs to patients after ACLR does not have a negative effect on graft survival, risk of revision, or risk of a KOOS-QOL score <44 at 2-year follow-up. We emphasize using caution when administering NSAIDs by keeping the duration and dosage of NSAIDs as short and low as possible to ensure sufficient pain relief while limiting unwanted exposure to any known and unknown adverse effects of these drugs.
