Abstract
BACKGROUND Bone grafting in patients with scaphoid waist nonunion can present several technical challenges. In this study, we aimed to present a modified surgical technique for scaphoid waist nonunion, which consisted of subchondral radial and ulnar K-wires positions with cancellous bone graft, and to compare the clinical outcome of this modified technique with the conventional method. METHODS We retrospectively reviewed 72 patients with scaphoid waist nonunion who had been surgically treated between January 2011 and December 2020. Of these, 34 patients were treated with the modified method and 38 with the conventional method. Debridement of the nonunion site was performed using a curette, rongeur, and microburr. Two or 3 K-wires were inserted along the cancellous portion of the scaphoid in the conventional method. In the modified method, 2 K-wires were inserted along the ulnar and radial subchondral portion of the scaphoid to increase the space for bone grafting in the cancellous portion of the scaphoid. The autologous cancellous bone grafted in both the methods. Demographic, radiological, and clinical outcomes were reviewed and compared between the groups. RESULTS There were no significant differences in demographics and characteristics of nonunion between the 2 groups of patients. The modified method group showed significantly shorter union time than the conventional method group (conventional group: 13.0 ± 1.3 weeks, modified group: 11.4 ± 1.1 weeks; P < 0.001). The bony union rate was 97.1% for the modified method and 89.5% for the conventional method. Satisfactory clinical outcomes (excellent and good Mayo wrist scores) were achieved in 27 cases (81.8%) using the modified method and 22 cases (64.7%) using the conventional method. CONCLUSION Subchondral radial and ulnar K-wire positioning with cancellous bone graft (modified method) can improve the union time with satisfactory clinical outcomes in the treatment of scaphoid waist nonunion.

Abstract
PURPOSE An array of fixation and grafting techniques for scaphoid nonunion have been described over time, achieving varied results pertaining to union and scaphoid alignment. The aim of this study was to check for union rates and correction of scaphoid parameters achieved by our technique of using screw as a strut and cancellous compression grafting harvested from the distal radius by a single volar approach. METHODS Retrospective analysis of all patients operated by the said technique was done from 2013 to 2019. Thirty-eight patients including 36 males and two females in the age range of 20-56 years were analyzed. Union rates, change in scaphoid alignment parameters and graft site characteristics were documented. RESULTS Of the patients analyzed, 5/38 were nonunions of proximal pole, 19/38 of waist and 14/38 were of distal pole which included nonunions of cystic type or with humpback deformity. Patients were followed up for an average of 22.2 months and union was achieved in all cases with a mean period of 15.7 ± 3.7 weeks. There was significant improvement in the scaphoid alignment postoperatively. One case of implant migration and one case of scaphoid nonunion advanced collapse were noted. The mean duration of donor site healing was noted to be 16.9 ± 2.5 weeks except two outliers which took longer time. There were no cases of donor site fracture or other complications. CONCLUSION Union rates, correction of scaphoid parameters and minimal complications justifies this technique as a novel one in the management of scaphoid nonunion at all levels, with minimal donor site morbidity and attained by the single volar approach.

Abstract
Introduction The scaphoid is the most common carpal bone to be fractured and has a high propensity for nonunion. Restoration of scaphoid length mitigates the chances of long-term complications. The aim of this study was to assess the functional outcome of the Fisk-Fernandez technique for the treatment of scaphoid nonunion by using open reduction and internal fixation with trapezoidal iliac crest bone graft. Materials and methods Fisk-Fernandez technique was used to manage scaphoid nonunion in 31 patients at a tertiary care hospital with follow-up at six weeks, 12 weeks, and 24 weeks. An objective assessment of the outcome was done using a comparison of the pre- and postoperative scaphoid score, QuickDASH, and visual analog score. Discussion The scaphoid is one of the most common carpal bones to get fractured. Anatomical factors, late presentation, and delay in diagnosis render it to usually land in nonunion. A comparison of the preoperative scaphoid, QuickDASH, and VAS scores with six-week, 12-week, and 24-week postoperative scores was made and was found to be statistically significant (p<0.001). Ninety-three percent of patients subjectively reported satisfaction after treatment. Though revascularization was not assessed, the bony union was observed in all the patients. Conclusion The operative technique proposed by Fisk-Fernandez is effective in correcting deformity of the scaphoid as well as providing satisfactory functional outcomes in patients with scaphoid nonunion.

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
AIMS The purpose of this systematic review was to determine the rates of union for vascularized versus non-vascularized grafting techniques in the operative management of scaphoid nonunion. Secondary aims were to determine the effect of the fixation techniques used, the source of grafting, as well as the influence of fracture location (proximal pole) and avascular necrosis (AVN). METHODS A search of PubMed, MEDLINE, and Embase was performed in June 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analyses statement and registered using the PROSPERO International prospective register of systematic reviews. The primary outcome was union rate. RESULTS There were 78 studies that met the inclusion criteria with a total of 7,671 patients (87.8% male, 12.2% female). The mean age was 27.9 years (SD 3.8) and the mean follow-up was 30.9 months (SD 25.9). The mean union rate was 88.7% (95% confidence interval (CI) 85.0 to 92.5) for non-vascularized grafts versus 87.5% (95% CI 82.8 to 92.2) for vascularized grafts (p = 0.685). Pooled analysis of trial data alone found a mean union rate of 82.4% (95% CI 66.9% to 97.9%) for non-vascularized grafts and 89.4% (95% CI 84.1% to 94.7%) for vascularized grafts (p = 0.780). No significant difference was observed in union rates between any of the fixation techniques used in the studies (p = 0.502). Distal radius and iliac crest graft source had comparable mean union rates (86.9% (95% CI 83.1 to 90.7) vs 87.6% (95% CI 82.2 to 92.9); p = 0.841). Studies that excluded patients with both proximal pole fractures and AVN (n = 14) had a mean union rate of 96.5% (95% CI 94.2 to 98.9) that was significantly greater than the mean union rate of 86.8% (95% CI 83.2 to 90.4) observed in the remaining studies (p < 0.001). CONCLUSION Current evidence suggests vascularized bone grafting does not yield significantly superior results to non-vascularized grafting in scaphoid nonunion management. However, potential selection bias lessens the certainty of these findings. The fixation type or source of the graft used was not found to influence union rates either. Sufficiently designed and powered prospective randomized controlled trials in this area are needed. Cite this article: Bone Joint J 2022;104-B(5):549-558.

Abstract
Purpose This study aims to introduce the “tripod” technique using cannulated compression screw and two anti-rotational K-wires for treatment of unstable scaphoid waist fracture nonunion, and to compare it with the single cannulated screw fixation technique in term of scaphoid union and surgical outcomes. Methods It was a retrospective study. From January 2014 to March 2020, 103 consecutive patients with scaphoid waist fracture nonunion treated with the tripod fixation and bone grafting (n = 45) or with single cannulated compression screw and bone grafting (n = 58) were included. All the procedures were performed by the same hand surgery team, and autologous cortico-cancellous radius bone graft was used for bony reconstruction. The minimal follow-up period was 12 months. The union rate and the time to union, range of motion (ROM), grip strength, Visual Analogue Scale (VAS), Quick Disabilities of the Arm, Shoulder and Hand (DASH) score and modified Mayo Scores at the last visit were compared. Results In tripod fixation group, bony union was achieved in all patients at the mean of 14.8 ± 3.8 weeks, while in the single cannulated screw fixation group the bony union rate was 94.8% (55/58) and the time to union was 17.6 ± 3.6 weeks. The difference of time to union was statistically significant (p = 0.027), but not for bony union rate (p = 0.122). At the last visit, no significant difference was found with respect to any clinical and radiographic outcome measures (all p > 0.05). The overall rate of complications was not significantly different between two groups (15.6% vs 10.3%, p = 0.430). Conclusions Tripod fixation technique with headless compression screw and two K-wires is a safe and effective technique for treatment of scaphoid nonunion fixation and can be considered to use in practice, especially for those potentially rotationally unstable cases.

Abstract
Objective This article compares predictors of failure for vascularized (VBG) and nonvascularized bone grafting (NVBG) of scaphoid nonunions.
Methods We conducted a systematic literature review of outcomes after VBG and NVBG of scaphoid nonunion. Fifty-one VBG studies (N = 1,419 patients) and 81 NVBG studies (N = 3,019 patients) met the inclusion criteria. Data were collected on surgical technique, type of fixation, time from injury to surgery, fracture location, abnormal carpal posture (humpback deformity and/or dorsal intercalated segmental instability [DISI]), radiographic parameters of carpal alignment, prior failed surgery, smoking status, and avascular necrosis (AVN) as defined by punctate bleeding, magnetic resonance imaging (MRI) with contrast, MRI without contrast, X-ray, and histology. Meta-analysis of proportions was conducted with Freeman–Tukey double arcsine transformation. Multilevel mixed-effects analyses were performed with univariable and multivariable Poisson regression to identify confounders and evaluate predictors of failure.
Results The pooled failure incidence effect size was comparable between VBG and NVBG (0.09 [95% confidence interval [CI] 0.05–0.13] and 0.08 [95% CI 0.06–0.11], respectively). Humpback deformity and/or DISI (incidence-rate radios [IRRs] 1.57, CI: 1.04–2.36) and lateral intrascaphoid angle (IRR 1.21, CI: 1.08–1.37) were significantly associated with an increased VBG failure incidence. Time from injury to surgery (IRR 1.09, CI: 1.06–1.12) and height-to-length (H/L) ratio (IRR 53.98, CI: 1.16–2,504.24) were significantly associated with an increased NVBG failure incidence, though H/L ratio demonstrated a wide CI. Decreased proximal fragment contrast uptake on MRI was a statistically significant predictor of increased failure incidence for both VBG (IRR 2.03 CI: 1.13–3.66) and NVBG (IRR 1.39, CI: 1.16–1.66). Punctate bleeding or radiographic AVN, scapholunate angle, radiolunate angle, and prior failed surgery were not associated with failure incidence for either bone graft type (p > 0.05).
Conclusion Humpback deformity and/or DISI and increasing lateral intrascaphoid angle may be predictors of VBG failure. Time from injury to surgery may be a predictor of NVBG failure. AVN as defined by decreased contrast uptake on MRI may be a marker of increased failure risk for both bone graft types.

Abstract
We compared two methods of fixation for unstable scaphoid waist nonunions regarding rate of scaphoid union, union time, deformity correction, clinical outcomes (pain, range of motion, and grip strength), and QuickDASH scores. Eighty-nine patients who undergo cancellous iliac bone grafting and internal fixation either with a Herbert screw (n = 46) or multiple Kirschner wires (n = 43) were evaluated. The rate of scaphoid union in the K-wire group was 98% (n = 42) versus 89% (n = 41) in the screw group. The mean union time and duration of surgery for K-wire group versus screw group were 12 versus 15 weeks and 45 versus 66 min respectively. There was no significant difference between the two groups with respect to deformity correction, clinical outcomes, and QuickDASH scores. Despite there was no significant difference in the rate of scaphoid union between the two fixation methods, the K-wires procedure had the advantages of short union time, less demanding, and less expensive than the screw implant.

Abstract
Scaphoid fractures, particularly those that occur more proximally, are unreliable in achieving union due to the retrograde blood supply of the scaphoid bone. Vascular compromise is associated with the development of nonunions and avascular necrosis of the proximal pole. Due to the tenuous blood supply of the scaphoid, it is imperative that the vascularity be assessed when creating diagnostic and treatment strategies. Early detection of vascular compromise via imaging may signal impending nonunion and allow clinicians to perform interventions that aid in restoring perfusion to the scaphoid. Vascular compromise in the scaphoid presents a diagnostic challenge, in part due to the non-specific findings on plain radiographs and computed tomography. Magnetic resonance imaging techniques have dramatically improved our ability to assess the blood supply to the scaphoid and improve time to intervention. This review aims to summarize these advances and highlights the importance of imaging in assessing vascular compromise in scaphoid nonunion and in reperfusion following surgical intervention.

Abstract
AbstractScaphoid nonunion has traditionally been treated by open surgery where the pseudarthrosis has been cleaned while either a structural wedged bone graft, or chips of cancellous bone has been used to fill the defect. K-wires or a screw has been used to stabilize the bone. Using the arthroscopic technique for treatment of nonunion of the scaphoid gives us small exposure to the joint, however with an excellent view of the bones, the articular surfaces and the intraarticular ligaments. The results from arthroscopic treatment for scaphoid nonunion with bone grafting using chips of cancellous bone are as good as from the open technique. The arthroscopic treatment, though, helps us to diagnose and treat concomitant lesions. There is less damage of blood supply, nerves and capsule, which might lead to a faster recovery and rehabilitation. The technique will be described and discussed.

Abstract
Many hand surgeons argue that vascularized bone grafting is indicated in proximal pole avascular necrosis, prior failed surgery, or long-standing scaphoid nonunion. However, the available evidence does not support improved treatment outcomes for vascularized bone grafting rather than traditional nonvascularized techniques. This article addresses the available evidence and examines the role of vascularized bone grafting in scaphoid nonunion treatment. It also identifies important factors that influence healing, clarifies the decision-making algorithm, and proposes areas for further research.

Abstract
Scaphoid fracture is the most common carpal fracture. Nonunion rate has been reported around 10 to 15% of scaphoid fractures. Risk factors for scaphoid nonunion are known as location, displacement, poor vascularity, time to treatment etc. The goals of surgical treatment for scaphoid nonunion are to achieve bony union, to correct carpal deformities and also to prevent progressive carpal instability and arthritis. Scaphoid nonunion can cause scaphoid nonunion advanced collapse (SNAC) which is a pattern of progressive degenerative radiocarpal and midcarpal arthritis secondary to posttraumatic pathomechanics of the scapholunate joint. Achieving bony union is essential to prevent carpal collapse or arthritis. To improve bony union, many surgical procedures including various forms of bone grafting have been developed and attempted. However, there is a controversy about which procedure is the most effective. In this review, we provide an overview of surgical treatment methods for scaphoid nonunion and discuss proper surgical strategies for scaphoid nonunion which requires surgical management.

Abstract
BACKGROUND Operative treatment of the scaphoid nonunion includes avascular corticocancellous and cancellous bone grafts and increasingly the use of vascular pedicled and free vascular corticocancellous grafts. Especially the latter require a fair amount of operative expertise and experience in microsurgical techniques. OBJECTIVE Which criteria lead to the decision for or against an avascular graft used for reconstruction of scaphoid nonunion? Is our current classification system of a scaphoid pseudarthrosis able to illustrate our diagnostic potential in a way that makes us refer to operative procedures? METHODS Evaluation of current literature and expert opinions RESULTS: Avascular bone grafts show a high union rate as long as a sufficient vascularisation of the remaining fragments is present. In general, patients benefit from a very good functional outcome. Even revisions of failed scaphoid union may be successfully treated with an avascular bone graft. Failures of union are repeatedly experienced in treating proximal pole fractures with critical vascularisation or extensive bone loss, especially including avascular necrosis of the proximal pole (AVN). Current classification systems do not allow description and correlation of morphologic findings so as to compare results profoundly and to recommend specific procedures. CONCLUSIONS As long as sufficient vascularisation of remaining fragments is seen, the avascular bone graft is eligible for reconstructing scaphoid nonunion. Classification systems do not seem to reflect the status quo of diagnostic possibilities and make it difficult to provide guidelines for state-of-the-art operative procedures.

Abstract
PURPOSE To evaluate a surgical technique of treating nondisplaced waist and proximal pole scaphoid nonunions without avascular necrosis (AVN). METHODS We performed a retrospective review of all patients with nondisplaced, scaphoid waist or proximal pole nonunions without AVN treated with the following technique. Two K-wires are positioned along the scaphoid axis to stabilize the proximal and distal poles. Debridement with a curette or burr is performed parallel to the nonunion site until the K-wires are visualized and punctate bleeding of the proximal and distal fragments is encountered. The volar, radial fibrous union is left intact. Distal radius cancellous bone graft is packed into the nonunion site. A headless screw is placed perpendicular to the fracture and the K-wires are removed. RESULTS Between 2012 and 2014, 12 patients (ages 13-29 y) with clinical and radiographic evidence (10 had computed tomography or magnetic resonance imaging; 2 had radiographs only) of scaphoid nonunion were identified (10 transverse waist and 2 proximal pole fractures). Median interval from injury to surgery was 38 weeks (range, 3 mo to 9 y). Four patients were active smokers and 2 had failed previous iliac crest bone grafting. All patients healed as confirmed by computed tomography. Average time to union was 14 weeks (range, 6-31 wk). Four patients had delayed union requiring a bone stimulator. All patients had resolution of pain and there were no complications. CONCLUSIONS The technique described is an effective and efficient method of treating nondisplaced scaphoid nonunions without AVN. We suggest that complete debridement of the nonunion is not essential to achieve union. In addition, pinning the proximal and distal scaphoid poles initially and maintaining the volar fibrous union of the scaphoid nonunion stabilizes the fracture fragments, increasing the technical ease of grafting and fixation. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Achieving stable fixation of displaced acute and chronic nonunited scaphoid fractures continues to be a challenge for the treating surgeon. The threaded compression screw has been the mainstay of treatment of these fractures for the last 3 decades; however, persistent nonunion after screw fixation has prompted development of new techniques. Recent results of volar buttress plating have been promising. We describe a novel technique of dorsal scaphoid plating. In contrast to volar plating, the dorsal plate is biomechanically more favorable as it utilizes the tension side of the scaphoid bone for dynamic compression. Dorsal scaphoid plating provides a more stable construct than the traditional Herbert screw and mitigates the need for vascular or corticocancellous bone grafting in most cases.

Abstract
The authors report the results of long-term follow-up in 29 patients treated for non-union of the carpal navicular with a modified Murray technique performed through a lateral approach. Mean patient age at surgery was 22.5 years. Average time from injury to surgery for nonunion was 18 months. In 5 cases, mild signs of osteoarthritis of the radioscaphoid joint (scaphoid nonunion advanced collapse [SNAC] stage I) were present before surgery, and in 2 cases, radiographic signs of avascular necrosis of the proximal nonunion fragment were evident. In all cases, a corticocancellous nonvascularized bone graft taken from the distal part of the ipsilateral radius was used. Mean follow-up was 11.2 years. Nonunion had healed in 93.1% of cases. At follow-up, the 2 patients in whom nonunion had not healed had severe painful osteoarthritis of the wrist (SNAC stage IV). Twenty patients were asymptomatic, and 5 had occasional pain in the wrist. Wrist range of motion was restricted in all patients compared with the contralateral side. Mild osteoarthritis was observed in 6 patients (SNAC stage I). The average Disabilities of the Arm, Shoulder and Hand score was 8.7 of 100. The modified Murray technique is reliable for treating nonunion of the carpal navicular. The union rate is high, and the incidence of wrist osteoarthritis is low compared with other studies. Early diagnosis and treatment of nonunion (a short interval between fracture and surgery) can minimize the risk of degenerative joint disease. Avascular necrosis of the proximal fragment is not an absolute contraindication to surgery.

Abstract
PURPOSE To determine by systematic review the optimal treatment of scaphoid nonunion. METHODS We conducted a systematic review of the literature with a meta-analysis of proportions to investigate the comparative effectiveness of different surgical techniques. RESULTS A total of 48 publications (1,602 patients) met the eligibility criteria. Vascularized and nonvascularized bone grafts had an estimated union incidence of 92% and 88%, respectively. Distal radius and iliac crest bone grafts had similar union rates (89% and 87%, respectively) but harvesting of iliac crest bone grafts had more complications. Both screw and K-wire fixation had a higher incidence of union (88% and 91%, respectively) than no fixation (79%). No approach was statistically different. Patients fixed with screws were mobilized earlier than those with K-wire fixation. CONCLUSIONS Current evidence does not demonstrate a significantly superior method for the treatment of scaphoid nonunion. A multicenter randomized trial would be ideal but the large numbers that would be required may make this unrealistic. We recommend the continued reporting of series with specific assessments and outcome measures to optimize future comparisons in an attempt to determine the best management of scaphoid nonunion. CLINICAL RELEVANCE The use of bone grafts and the methods of their fixation for scaphoid nonunion are debated issues in hand and wrist surgery, with multiple methods employed. There is no current consensus on optimal treatment. A meta-analysis of proportions of available data from recent studies was deemed the most appropriate way to assimilate the available evidence with the view to inform surgeons of the optimal treatment according to the evidence base.

Abstract
AIM The aim of the study was to evaluate the clinical and radiological results obtained in the treatment of carpal scaphoid non-union treated at the University Hospital of Valladolid using the Fisk Fernandez technique. MATERIAL AND METHODS A review was performed on 43 cases of surgically treated non-union using Fisk Fernandez technique with a minimum of 6 months follow-up. The time until surgery, previous treatment, the mechanism of injury, type of non-union, and the existence of radio-carpal arthrosis were evaluated. A subjective evaluation was performed using the "Scaphoid Score" and the DASH, plus an objective assessment with the modified Green & O'Brien, together with the measurement of the intra-scaphoid, radioulnar, scapholunate angles, and carpal height. RESULTS The median time to healing in the series was between 16 to 24 weeks, except in 3 patients who failed to heal and required salvage surgery. There was a statistically significant variation between the preoperative and postoperative angles and carpal height measured in the X-rays. DISCUSSION There are different osteosynthesis techniques and materials for the treatment of non-union. The evaluation of results performed using objective and subjective scales showed variable results between studies. Different techniques are aimed at preventing the progression of the disease. CONCLUSION The Fisk Fernandez technique enables the deformity of the scaphoid to be corrected by wedge grafting and internal fixation with Kirschner wires or screws.

Abstract
We reviewed 17 patients 64 (range 29-123) months after dorsal radioscaphoid capsulodesis for scapholunate dissociation. Mean loss of key pinch was 13%, grip strength 18%, wrist flexion 22% (p < 0.001), and total wrist ROM 17% (p < 0.005). VAS (0 = best; 100 = worst) was 30(±28) for pain, 43(±30) for function, and 33(±33) for general satisfaction with the outcome. Mean Quick-DASH and PRWE scores were 27 and 34, respectively. The mean scapholunate gap was 3.5 mm before surgery, 1.9 mm after surgery, and 3.3 mm at review. The corresponding scapholunate angles were 63°, 46°, and 70°, respectively. The mean radioscaphoid angle with the wrist maximally flexed was 84° (69-99) for the patients and was 91° (77-103) in ten wrists of volunteers. Six patients had changed their jobs because of the wrist. Three patients stated that they would not have consented to operation if they had known the outcome in advance. Radioscaphoid capsulodesis does not prevent volar flexion of the scaphoid.

Abstract
This study was performed to determine whether pure cancellous bone graft and Kirschner (K-) wire fixation were sufficient to achieve bony union and restore alignment in scaphoid nonunion. A total of 65 patients who underwent cancellous bone graft and K-wire fixation were included in this study. The series included 61 men and four women with a mean age of 34 years (15 to 72) and mean delay to surgery of 28.7 months (3 to 240). The patients were divided into an unstable group (A) and stable group (B) depending on the pre-operative radiographs. Unstable nonunion was defined as a lateral intrascaphoid angle > 45°, or a radiolunate angle > 10°. There were 34 cases in group A and 31 cases in group B. Bony union was achieved in 30 patients (88.2%) in group A, and in 26 (83.9%) in group B (p = 0.439). Comparison of the post-operative radiographs between the two groups showed no significant differences in lateral intrascaphoid angle (p = 0.657) and scaphoid length (p = 0.670) and height (p = 0.193). The radiolunate angle was significantly different (p = 0.020) but the mean value in both groups was < 10°. Comparison of the dorsiflexion and palmar flexion of movement of the wrist and the mean Mayo wrist score at the final clinical visit in each group showed no significant difference (p = 0.190, p = 0.587 and p = 0.265, respectively). Cancellous bone graft and K-wire fixation were effective in the treatment of stable and unstable scaphoid nonunion. Cite this article: Bone Joint J 2013;95-B:809–14.

Abstract
OBJECTIVES Scaphoid nonunion is relatively rare in children and adolescents, and no long-term follow-up has been reported. DESIGN Retrospective follow-up study. PATIENTS Eleven patients (10 boys and 1 girl), mean 15.2 (13.9-15.9) years of age, with scaphoid nonunion and open growth plates were operated with bone grafting, Kirschner-wire fixation and 12 weeks of cast immobilization. MAIN OUTCOME MEASUREMENTS Bony union, degenerative wrist changes, and restoration of the carpal architecture were assessed with CT and radiographs. Clinical parameters included active range of motion, grip strength, key pinch strength, and subjective outcome scores (quick disabilities of arm, shoulder and hand (DASH), visual analog scale). RESULTS The patients were followed up after mean 6.9 (3.1-15.1) years; all patients attended. Radiographs and CT confirmed healing of all nonunions, the carpal anatomy was restored, and the wrists were rated as 0 according to the scaphoid nonunion advanced collapse, without degenerative changes. The clinical result was excellent with visual analog scale at rest = 1, at activity = 6, and quick DASH score = 3.3. Active range of motion and grip strength were insignificantly reduced (14 degrees and 2 kg); the key pinch strength remained similar. CONCLUSIONS Healing of a scaphoid nonunion can be expected in adolescents after open reduction, Kirschner-wire fixation, bone grafting, and plaster immobilization, resulting in pain relief and excellent wrist function without degenerative changes after longer term follow-up. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
OBJECTIVES Untreated scaphoid nonunions are a hazard to the wrist, resulting in deteriorating function and radiologic degenerative changes with increasing time. Long-term results after surgery of scaphoid nonunion reporting clinical, radiologic, and subjective outcomes are scarce. DESIGN Retrospective follow-up study. PATIENTS From 1990 to 1998, 53 patients were operated on for persistent scaphoid nonunion; three patients were excluded from the follow-up (one expelled foreigner, another died of an unrelated cause, one never appeared after surgery), leaving 50 patients eligible for follow-up. INTERVENTION All patients were operated on with open reduction and internal fixation; the majority also received a bone graft. MAIN OUTCOME MEASUREMENTS Radiology and computed tomography verified union, degenerative wrist changes, and final salvage treatment. Range of motion, grip strength, key pinch, and subjective outcome (QuickDASH, visual analog scale). RESULTS Fifty patients were followed up after a mean of 12.2 years (standard deviation [SD], 3.0), 47 by clinical and radiologic examination; three were interviewed by telephone and completed QuickDASH and visual analog scale forms. Union was achieved in 45 of 50 scaphoids and an additional two after a second attempt. Five patients (one persistent and four healed nonunions) underwent salvage procedures. Grip strength (41 vs 45 kg, P = nonsignificant), key pinch (11.5 vs 12.4, P = nonsignificant), and active range of motion (186° vs 214°, P < 0.001) were slightly reduced compared with the uninjured side. The subjective outcome was good (mean visual analog scale = 7, mean QuickDASH = 9.1). Minor degenerative changes were seen in nine wrists at surgery and 22 at follow-up. CONCLUSION Healing of a scaphoid nonunion provides long-term pain relief, excellent wrist function, and halts degenerative changes in the majority of patients. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND The aim of this study was to analyze the long-term results of a modified Matti-Russe technique for the treatment of scaphoid non-union and pseudarthrosis. The modification was based on the use of bone graft taken from the ipsilateral distal radius, rather than from the iliac crest, as originally described. MATERIAL/METHODS Between 1987 and 2000, 23 consequent male patients with scaphoid waist non-union or pseudarthrosis underwent surgery by a modified Matti-Russe technique. During the 5-year follow-up, patient evaluation was based on radiological findings and the Green and O'Brien scoring system. RESULTS Anatomy was restored and healing of the non-union was achieved in 21 (91.3%) patients. The other 2 patients failed to achieve union and underwent the same operation a second time, which was successful. According to the Green and O'Brien scoring system, 82.6% (19/23) of patients showed excellent results and 17.4% (4/23) showed good results at 2-year follow-up. At 5-year follow-up, 73.9% of patients (19/23) had excellent results and 26.0% (4/23) had good results. No early post-operative complications developed. Two patients demonstrated mild radiological radio-scaphoid arthritis at 2.5 years postoperatively. All patients returned to previous levels of activity. CONCLUSIONS The standard Matti-Russe technique is an old but reliable and inexpensive method for the treatment of long-standing or neglected scaphoid non-unions or pseudarthroses. The modification of this established method, based on use of the distal radius as a donor site, reduces operative time, can be performed through a single approach, does not show donor site morbidity, and allows the use of regional anaesthesia.

Abstract
Eighteen patients who underwent revision non-vascularized bone grafting and internal fixation after failed surgery for scaphoid nonunion were reviewed after a minimum of 8.2 years. Eleven of the nonunions were located in the middle and seven in the proximal third of the scaphoid. The mean interval between injury and the revision procedure was 6 years. Sixteen of the 18 nonunions healed, two after a third attempt. Three patients with healed nonunions and one patient with persistent nonunion required salvage procedures for progressive radiocarpal arthrosis. In the remaining 14 cases, the mean loss of wrist flexion/extension arc compared to the contralateral wrist was 36 degrees . Mean reduction of grip strength and key pinch was 9.3 kg and 0.9 kg respectively. The QuickDASH score was 18 and a visual analogue pain score was 21/100 at follow-up. Wrist degeneration increased in all but one case during the observation period. Thirteen of 16 patients with union and one patient with a persisting nonunion experienced moderate symptoms.

Abstract
Scaphoid fractures are common but present unique challenges because of the particular geometry of the fractures and the tenuous vascular pattern of the scaphoid. Delays in diagnosis and inadequate treatment for acute scaphoid fractures can lead to nonunions and subsequent degenerative wrist arthritis. Improvements in diagnosis, surgical treatment, and implant materials have encouraged a trend toward early internal fixation, even for nondisplaced scaphoid fractures that could potentially be treated nonoperatively. Despite the advent of newly developed fixation techniques, including open and percutaneous fixation, the nonunion rate for scaphoid fractures remains as high as 10% after surgical treatment. Scaphoid nonunions can present with or without avascular necrosis of the proximal pole and may show a humpback deformity on the radiograph. If left untreated, scaphoid nonunions can progress to carpal collapse and degenerative arthritis. Surgical treatment is directed at correcting the deformity with open reduction and internal fixation with bone grafting. Recently, vascularized bone grafts have gained popularity in the treatment of scaphoid nonunions, particularly in cases with avascular necrosis. This article reviews current concepts regarding the treatment of scaphoid fractures and nonunions.
