[PMID: 36765020 PMCID: PMC9916497 DOI: 10.1186/s10195-023-00686-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 01/21/2023] [Indexed: 02/12/2023] Open
Abstract
BACKGROUND Allograft bone screws are rarely described for the fixation of the scaphoid. When fresh fractures are treated, metal screws are mainly used; when pseudarthrosis is the indication, plates in combination with vascularized or non-vascularized bone grafts are mainly used. The necessity of metallic screw removal is under debate, but it is mandatory for plates because of movement restrictions due to the plate. The use of biomaterials in scaphoid fracture fixation was described as leading to union rates of between 64 and 100%. Brcic showed the incorporation of an allogeneic cortical bone screw at 10 weeks postoperative, along with revascularization and stable osteosynthesis with primary bone healing, without any signs of immunological rejection. The purpose of this retrospective study was to explore the results obtained using an allogenic cortical bone screw (Shark Screw®) in patients with fresh scaphoid fracture fixation and pseudarthroses with respect to union rates and time to union. PATIENTS AND METHODS We retrospectively analyzed 75 patients: 31 with fresh fractures and 44 pseudarthrosis patients. The Shark Screw® was used for the fixation of the scaphoid in the fresh-fracture and pseudarthrosis patients. We evaluated the union rate, complication rate and time to union. RESULTS Using the human allogeneic cortical bone screw for scaphoid fracture fixation led to a high union rate (94-96%). There were two nonunions in the fresh fracture group and two nonunions in the pseudarthrosis group. The complication rate was 1.3% (1 patient). Median time to union was 16, 18 and 29 weeks for the fresh-fracture, pseudarthrosis and delayed-union patients, respectively. The treatment of fresh scaphoid fractures and pseudarthroses showed similar union rates to those described in the literature, uses a shorter and less invasive surgical method with no need for hardware removal, and has a low complication rate. CONCLUSION Using the human allogenic cortical bone screw (Shark Screw®) led to similar union rates in fresh fractures-but better union rates in pseudarthrosis patients-compared to those presented in the literature for other scaphoid fracture fixation techniques, and it enabled a short and low-invasive procedure without any donor site morbidity and without the necessity to remove the hardware in a second surgery. The pseudarthrosis patient group showed a particularly strong benefit from this new procedure. The physiological bone metabolism remodels the cortical bone screw without scars. LEVEL OF EVIDENCE III: retrospective cohort study, therapeutic investigation of a treatment.

Abstract
INTRODUCTION Scaphoid is the most fractured carpal bone, with a 5-10% nonunion rate. Treatment challenges include choosing the implant and graft that best corrects humpback deformity and carpal malalignment with higher chances of bony healing. OBJECTIVE Compare cortico-cancellous and cancellous grafts between two groups of patients treating scaphoid nonunion with locking plates using autologous bone graft and evaluate bone healing rates and radiographic, tomographic, and functional parameters before and after surgery. METHODS Non-randomized prospective study including 20 cases of scaphoid nonunion. Groups were divided into Group A (ten patients treated with cortico-cancellous iliac graft) and Group B (ten patients treated with cancellous iliac graft). Patients underwent pre- and postoperative radiographs, computed tomography, and functional evaluation. RESULTS In postoperative analysis, Group A showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle (p = 0.011) correction when comparing the pre- and postoperative periods. Group B showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle correction (p = 0.0018), grip strength (p = 0.002), and tip pinch strength (p = 0.001) when comparing the pre- and postoperative periods. By comparing both groups, Group B showed a statistically significant difference in intrascaphoid angle correction (p = 0.002), grip strength (p = 0.002), tip pinch strength (p = 0.002), and radial deviation (p = 0.0003). There was no statistical difference when comparing bony healing between groups. CONCLUSION Scaphoid nonunion treatment with a locking plate was effective, showing a high bony healing rate and improved carpal alignment in imaging tests for both graft types. However, results for intrascaphoid angle correction, grip strength, tip pinch strength, and radial deviation were better in Group B. LEVEL OF EVIDENCE IV, case series.

Abstract
Introduction Treatment of scaphoid fracture is challenging due to its unique blood supply and geometry. Traditionally, a headless compression screw is the standard treatment for unstable scaphoid fracture. Some fractures are complex, for example, comminution with bone loss. A scaphoid plate is an option in these difficult fractures providing adequate rotational stability. Aim To share our experience in using scaphoid plates in complex wrist trauma and comminuted fractures. Method and material Complex wrist trauma involving scaphoid fractures that were comminuted and multi-fragmentary fractures treated with plate osteosynthesis were retrospectively reviewed between July 2019 and September 2021. Patient demographic data, preoperative radiographs, CT scans, pain, wrist range of motion, and fracture union rate to union were reviewed. Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH®) score was recorded at 1-year postoperative follow-up. Results Nine patients associated with complex wrist trauma were included in this case series. The mean follow-up was 2.5 years (13-30 months). The union rate was 100%. The mean arc of motion was 105° (95-110°). QuickDASH® score was 19.96 at 1-year postoperative follow-up. Four patients had good outcomes, four satisfactory, and one poor outcome. One hardware complication was observed which was the impingement of the plate proximally over the articular surface of the distal radius. Conclusion A scaphoid plate is a reliable option for treating complex and difficult fractures. It provides adequate stability, especially in comminution, bone loss, or multi-fragmentary fractures which are not amendable using other fixation methods. We recommend the expansion of plate osteosynthesis beyond scaphoid nonunion into complex wrist trauma.

Abstract
The scaphoid is the largest of the carpal bones, articulating with both proximal and distal carpal rows. If scaphoid fractures are not appropriately diagnosed and treated, there is a risk of nonunion, osteonecrosis and degenerative arthritis. Operative management of the scaphoid fracture is primarily determined by the fracture location and amount of displacement. There is increased momentum for dual screw fixation constructs, intended to provide greater stability and reduce the risk of nonunion. Our current practice is to utilize two screws without graft as a first-line treatment for scaphoid nonunion with or without humpback deformity and cyst formation. This review will discuss the management of acute scaphoid fractures and the treatment of nonunion.

Abstract
BACKGROUND The purpose of this study was to evaluate the rate of union of scaphoid fractures managed with volar plating and assess postoperative complications. METHODS Retrospective consecutive case series of 28 patients with scaphoid fractures, 9 acute and 19 chronic nonunions, undergoing surgical fixation with volar scaphoid plating by a single surgeon between 2013 and 2019. Patients were followed up for a minimum of 3 months with scaphoid bony union being confirmed on radiograph or computed tomography. Postoperative complications and need for plate removal were recorded. RESULTS Overall union rate of 96% with all 19 chronic nonunions demonstrating radiological union and 1 of 9 acute fractures not uniting and requiring revision surgery. The only postoperative complication identified was symptomatic plate impingement which necessitated plate removal in 57% of cases. CONCLUSIONS This case series demonstrates volar plating of scaphoid fractures can be used as an alternative technique to achieve union.

Abstract
INTRODUCTION Over the past years, different fixation techniques focused on rotational stability in order to increase stability and stimulate union rates. Additionally, extracorporeal shockwave therapy (ESWT) has gained importance in the treatment of delayed and nonunions. Purpose of this study was to compare the radiological and clinical outcome of two headless compression screws (HCS) and plate fixation in scaphoid nonunions, in combination with intraoperative high energy ESWT. MATERIALS AND METHODS Thirty-eight patients with scaphoid nonunions were treated by using a nonvascularized bone graft from the iliac crest and stabilization with either two HCS or a volar angular stable scaphoid plate. All patients received one ESWT session with 3000 impulses and energy flux per pulse of 0.41 mJ/mm2 intraoperatively. Clinical assessment included range of motion (ROM), pain according to the Visual Analog Scale (VAS), grip strength, disability of the Arm Shoulder and Hand Score, Patient-Rated Wrist Evaluation Score, Michigan Hand Outcomes Questionnaire and modified Green O'Brien (Mayo) Wrist Score. To confirm union, a CT scan of the wrist was performed. RESULTS Thirty-two patients returned for clinical and radiological examination. Out of these, 29 (91%) showed bony union. All patients treated with two HCS compared to 16 out of 19 (84%) patients treated by plate showed bony union on the CT scans. The difference was not statistically significant. However, at a mean follow-up interval of 34 months, no significant differences could be found in ROM, pain, grip strength and patient-reported outcome measurements between the two HCS and plate group. Height-to-length ratio and capitolunate angle improved significantly in both groups compared to preoperative. CONCLUSIONS Scaphoid nonunion stabilization by using two HCS or angular stable volar plate fixation and intraoperative ESWT results in comparable high union rates and good functional outcome. Due to the higher rate for a secondary intervention (plate removal), HCS might be preferable as first choice, whereas the scaphoid plate fixation should be reserved for recalcitrant (substantial bone loss, humpback deformity or failed prior surgical intervention) scaphoid nonunions.

Abstract
INTRODUCTION Metal implants and bioabsorbable implants are frequently used in orthopaedic surgery, but they have some disadvantages. The usefulness of autologous bone has been described, and a method to precisely process autologous bone into implants such as screws and apply the implants clinically has been desired. We created a new system for manufacturing autologous bone screws during surgery and report five cases of scaphoid nonunion treated with precise autologous bone screws made from the tibial cortex using the new system. PATIENTS AND METHODS From 2012 through 2017, seven patients were diagnosed with scaphoid nonunion at our hospital and based on the inclusion/exclusion criteria, five of them were analyzed herein. The surgery was performed according to Zaidemberg's technique. The bone screw in each case was made from autologous tibial cortex using a numerically controlled lathe (model MTS4, Nano Co., Yokohama, Japan) under sterile conditions. The change in each patient's modified Mayo wrist score between the preoperative examination and at the final survey was determined, as were complications. RESULTS The median modified Mayo wrist score improved significantly from 65 to 95 points. All patients who were followed for > 2 years fused at a median duration of 3.5 months. Bone regeneration was confirmed at the donor sites in all cases. One fracture at the donor site occurred as a severe complication. CONCLUSIONS Precisely shaped autologous bone screws manufactured by a computer-assisted machine, together with a vascularized bone graft, may be a useful technique for treating scaphoid nonunions; these screws had good stability and bone replacement. Careful observation of the donor site is required. LEVEL OF EVIDENCE IV.

Abstract
Purpose This study reports the clinical outcomes of double-screw fixation with bone grafting for displaced scaphoid nonunions. Patients and methods This study was a retrospective survey. From January 2018 to December 2019, 21 patients with displaced scaphoid fractures underwent open debridement and two headless compression screw fixation with bone grafting. The preoperative and postoperative lateral intrascaphoid angle (LISA) and scapholunate angle (SLA) were recorded. Preoperative and postoperative grip strength (% of the healthy side), active range of motion (AROM), visual analogue scale (VAS), and patient-rated wrist evaluation (PRWE) scores at the final follow-up were obtained for all patients for comparison. Results Patients were treated for an average of 38.3 months (range 12-250) after the injury. The average time of postoperative follow-up was 30.5 months (range 24-48). All fractures achieved union at a mean of 2.7 months (range 2-4) after surgery, and 14 scaphoids of 21 patients (66.7%) healed by 8 weeks. CT scans showed no evidence of cortical penetration of either screw in all patients. There was a statistically significant improvement in AROM, grip strength, and PRWE. No complications occurred in this study, and all patients returned to work. Conclusion This study indicates that double-screw fixation with bone grafting is an effective technique for treating displaced scaphoid nonunions.

Abstract
The scaphoid is predisposed to nonunion after fracture because of its tenuous blood supply and propensity for delayed diagnosis. Many surgical techniques exist and continue to be developed to treat scaphoid non-unions. However, with variability in patient presentation, differences in nonunion location and type, and multiple bone graft sources and fixation options, selecting a surgical strategy proves a difficult task. The goal of this article is to provide an updated review of surgical strategies used to treat scaphoid nonunions. Particular attention is paid to methods of fixation as well as the ongoing debate over indications for structural and vascularized bone grafting. [Orthopedics. 2022;45(5):e235-e242.].

Abstract
OBJECTIVE Minimally invasive arthroscopically assisted reconstruction of scaphoid nonunions. INDICATIONS Delayed union or nonunion of the scaphoid with sclerosis and with indication for bone transplantation. Limited arthritic changes at the radial styloid. CONTRAINDICATIONS Severe humpback deformity with dorsal intercalated segment instability. Midcarpal arthritic changes. SURGICAL TECHNIQUE Supine position with the forearm upright and in neutral position, the elbow flexed by 90°, axial traction of 3 to 4 kg. Standard wrist arthroscopy via the 3-4 and the 4-5 portal and the midcarpal joint via the radial and ulnar portal, respectively, with sodium chloride as arthroscopy medium. Change of the optic to the ulnar midcarpal portal and opening of the nonunion with an elevator via the radial midcarpal portal. Resection of the sclerosis with a 3.0 mm burr while irrigating the joint. Harvesting of cancellous bone via the second extensor compartment. On the hand table, closed reduction by joy-stick K‑wires if needed and insertion of K‑wires for the scaphoid screw. Insertion of the screw without entering of the distal thread into the bone. Arthroscopic insertion of the bone transplant by a blunt drill sleeve via the radial portal with steady compression by the obturator. Complete insertion of the screw under arthroscopic control of the compression of the nonunion space with arthroscopic control of stability with the probe. POSTOPERATIVE MANAGEMENT Six weeks forearm cast including the thumb metacarpophalangeal joint, radiographic control and non-load bearing movements for two more weeks, CT scan in the oblique sagittal plane after 8 weeks, and increase of load, as well as physiotherapy on demand depending on the radiographic results. RESULTS To date, 17 patients with a mean age of the nonunion of 18 months were treated. In 14 patients, bony union was achieved after 8 weeks. In one patient, an extraosseous screw placement was corrected. In another patient with extraosseous screw placement, persisting nonunion was treated with an angular stable plate. One scaphoid demonstrated an asymptomatic tight nonunion after 14 months, while one scaphoid with sclerosis of the proximal pole did not heal.

Abstract
We conducted a systematic review of scaphoid plating for recalcitrant scaphoid fractures using EMBASE, Pubmed, Cochrane and MEDLINE. Thirteen studies were included. Ninety-three per cent of cases reported were male with a mean age of 27 years. Bony union was reported in eleven studies and achieved in 72% to 100% of cases. Scaphoid plates showed no significant difference in union incidence compared with headless compression screws. Mean removal incidence of plates was 21%. Postoperative flexion-extension arc was 119°. Grip strength improved by 14% postoperatively over that before surgery. There was a general improvement in patient-reported outcome measures. Eighty-six per cent of reported participants returned to their previous work. In these clinical reports, plates frequently required removal more frequently than headless compression screws.

[PMID: 34109071 PMCID: PMC8169164 DOI: 10.1055/s-0040-1721405] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 10/19/2020] [Indexed: 10/22/2022]
Abstract
Background Headless compression screw fixation with bone grafting has been the mainstay of treatment for scaphoid nonunion for the past several decades. Recently, locked volar plate fixation has gained popularity as a technique for scaphoid fixation, especially for recalcitrant or secondary nonunions. Purpose The purpose of this meta-analysis was to compare union rates and clinical outcomes between locked volar plate fixation and headless compression screw fixation for the treatment of scaphoid nonunions. Methods A literature search was performed for studies documenting treatment outcomes for scaphoid nonunions from 2000 to 2020. Inclusion criteria consisted of (1) average age > 18 years, (2) primary study using screw fixation, plate fixation, or both, with discrete data reported for each procedure, and (3) average follow-up of at least 3 months. Exclusion criteria consisted of studies with incomplete or missing data on union rates. Data from each study was weighted, combined within treatment groups, and compared across treatment groups using a generalized linear model or binomial distribution. Results Following title and full-text review, 23 articles were included for analysis. Preoperatively, patients treated with plate fixation had significantly longer time from injury to surgery and were more likely to have failed prior surgical intervention. There was no significant difference between union rates at 92 and 94% for screw and plate fixation, respectively. However, plate fixation resulted in longer time to union and lower modified Mayo wrist scores. Conclusion Patients treated with locked volar plate fixation were more likely to be used for recalcitrant or secondary nonunions. There was no statistically significant difference in union rates between screw and plate fixation. The results from this meta-analysis support the select use of locked volar plate fixation for scaphoid nonunion, especially recalcitrant nonunions and those that have failed prior surgical repair.

Abstract
The aim of this study was to evaluate the mid-term results of surgically treated scaphoid fractures since we were concerned that good results might deteriorate over time due to osteoarthritis or functional impairment. Thirty-three out of 121 surgically treated patients (isolated scaphoid fractures n = 23; scaphoid fractures with concomitant injuries n = 10) were evaluated retrospectively (47-138 months). Five patients (4%) had a non-union after internal fixation and were excluded because of additional treatment. The remaining 83 patients were not available for a follow-up examination. Patients with an isolated scaphoid fracture had a mean extension-flexion of 68°-0°-64°, a radial-ulnar deviation of 27°-0°-41° and a grip strength of 39 kg (corresponding to 87-98% of the uninjured contralateral wrist), while patients with concomitant injuries had a mean extension-flexion of 60°-0°-44°, radial-ulnar deviation of 22°-0°-38° and a grip strength of 42 kg (corresponding to 73-98% of the uninjured contralateral wrist). The Michigan Hand Questionnaire score was 85 and 75 and the Patient-Rated Wrist Evaluation score was 8 and 21, respectively. Fifteen patients had radiological signs of radiocarpal osteoarthritis with a significantly higher occurrence in those who had concomitant injuries compared to those with isolated scaphoid fractures (p < 0.01). There was no significant group difference in scaphotrapeziotrapezoid (STT) osteoarthritis (p = 0.968). One STT osteoarthritis case occurred after plate fixation, one after antegrade screw fixation and 10 after retrograde screw fixation. Surgical treatment of an acute isolated scaphoid fracture has excellent clinical, functional, and radiologic mid-term results, while scaphoid fractures with concomitant wrist injuries have slightly inferior results.

Abstract
Purpose This randomized clinical trial investigated the potential for early mobilization of the wrist following open reduction and internal fixation (ORIF) with a scaphoid specific volar locking plate and non-vascularized bone graft for scaphoid non-union. Methods 16 patients with scaphoid non-union underwent internal fixation with a scaphoid-specific volar locking plate and iliac crest bone graft and were randomized to one of two treatment arms (A) The control were immobilized in a below elbow cast for 6 weeks (n = 9) and (B) The experimental arm were mobilized early with a removable wrist splint (n = 7). Outcomes were measured preoperatively, and at 3 months post operatively. These included the primary outcome of union, and secondary outcomes of grip strength and patient reported outcomes of disabilities of arm shoulder and hand (DASH) and patient reported wrist evaluation (PRWE). Discrete variables were analyzed using the chi squared test while continuous variables used the students t-test. Results The experimental (early mobilization) group developed metalware complications resulting in the early termination of the study. No significant difference in the demographic characteristics of age, gender, time to surgery, smoking status and handedness was found between groups. A significant difference was found in BMI, with significantly higher proportion of obese patients (p = 0.05) in the experimental group. There was no significant difference in the primary outcome measure of the rate of union between groups. The secondary outcomes of grip strength, Dash and PRWE also showed no significant difference between the immobilized and mobilized groups. Conclusion We recommend immobilization following scaphoid non-union ORIF using a volar locking plate due to high complication rates in our cohort with early mobilization.Type of study/level of evidence: Therapeutic 2.Trial registration.Australian New Zealand Clinical Trials Registry (ACTRN12614001050640).

Abstract
Background Fractures through the waist of scaphoid are a common injury, resulting in deformity or nonunion. Recently, a locking plate has been shown to fix deformity or nonunion of scaphoid, with limited observation of functional postoperative outcomes. Objectives We present a case series of 16 patients, with the disabilities of the arm, shoulder, and hand (DASH) score evaluation in primary fixation of scaphoid fractures with humpback deformity ( n = 11) and revision open reduction internal fixation (ORIF) for nonunion ( n = 5), using the Medartis TriLock 1.5 scaphoid plate and bone grafting. Patients and Methods DASH scores were obtained preoperatively and postoperatively at 3, 6, and 12 (if required) months. Patient demographics, smoking status, employment type, and grip strengths were recorded. Results Thirteen patients attended follow-up. Union was clinically and radiologically assessed with 13 achieving union. The mean preoperative DASH score was 34.0 ( n = 16) and at treatment completion (discharge or DNA) was 11.5 ( n = 13), with mean reduction of 18.5 ( p = 0.03). At treatment completion, mean reduction in DASH score of revision ORIF was 13.7 ( p = 0.27; n = 4), compared with 20.7 ( p < 0.01; n = 9) in primary fixation with plate. Conclusions Deformity correction, reduction in DASH score, and rate of union make the plate system useful in the management of scaphoid fractures with humpback deformity and revision for nonunion. Level of Evidence This is a Level IV study.

Abstract
Background The volar scaphoid plate from Medartis (Medartis AG, Austrasse, Basel, Switzerland) is a variable angle titanium locking plate, preformed for the volar aspect of the scaphoid. It does not have compressive capability, and may act as a bridging device. It may provide an advantage over a compression screw where the pathoanatomy is less favorable to such a device with increased rotational stability. It may act as a buttress plate for correction of humpback deformity for example. It has been used in nonunions and with vascularized grafts. Questions Our study aims to assess the results of our patients with scaphoid nonunion treated with scaphoid volar plating over a larger number of patients. We aim to identify techniques to increase the success of plating. Methods Patients from our cohort were retrospectively reviewed. Operations were performed by three hand fellowship trained surgeons and in two centers. Inclusion involved a scaphoid plate procedure for a nonunion of the scaphoid with a minimum of 6 months of follow-up. Exclusions were those who had less than 6 months of follow-up. Data included demographics, patient-rated wrist evaluation (PRWE), a quick disabilities of the arm, shoulder, and hand (qDASH), visual analogue score, and range and grip. Radiology was reviewed. Results Thirty-two eligible patients were assessed. The mean age was 25 years (range 13-46), 2 were female and 15 were smokers. Mean follow-up postsurgery was 18 months. Twenty-nine of 32 patients united (90.6%) on computed tomography scan. Clinical assessment was performed in the 25 patients. The mean qDASH score was 12.5 (range 0-42) and mean PRWE was 11 (range 0-54). The mean arc of motion was 115 degrees. The mean grip strength was 39 kg compared with 41 kg on the nonoperated side. Conclusion We postulate that the plate acts like an internal bridging device, acting over a small distance, and inherent stability of the construct with structural graft and accurate reduction prior to plating is advantageous. Potential problems include plate impingement on the volar lip of the radius, particularly when trying to plate more proximal fractures. Ideally, it is utilized for mid to distal waist fractures.

Abstract
INTRODUCTION This study evaluated the use of a free vascularized bone graft with and without cartilage from the medial femoral condyle (MFC) in patients with recalcitrant scaphoid non-union, with a special focus on union rates and the osteochondral graft for proximal pole destruction. MATERIALS AND METHODS Thirty-eight avascular scaphoid non-unions in 37 patients who were treated with a free osteoperiosteal or osteochondral MFC graft were retrospectively evaluated (mean follow-up 16 months). Bone union, the scapholunate and the radiolunate angles were evaluated on X-ray images. The range of motion, grip strength, VAS, DASH and PRWE scores were evaluated clinically. RESULTS The overall union rate was 95%. Bone union was achieved in 27 out of 29 (93%) scaphoids treated with a free osteoperiosteal MFC grafts and in 9 out of 9 (100%) scaphoids treated with a free osteochondral MFC graft. The range of motion remained almost unchanged, while grip strength increased significantly (34 kg vs. 44 kg) and the VAS (22-5), DASH (59-19) and PRWE (62-30) score decreased significantly. The scapholunate (71°-65°) and radiolunate (28°-18°) angle decreased. No major donor site morbidity was observed. Postoperative complications were observed in eight cases (21%). CONCLUSIONS The vascularized medial femoral bone graft leads to a good functional outcome in the treatment of scaphoid non-unions. The graft provides adequate blood supply and structural stability to the scaphoid. A proximal pole destruction can be replaced using an osteochondral graft with promising short-term results preventing carpal osteoarthritis and collapse.
