Abstract
Background: Several operative treatments exist for scaphoid fractures, varying by approach (e.g., ercutaneous, volar, or dorsal), implant type (e.g., screw or Kirschner wire), and bone raft choice (e.g., none, nonvascularized, or vascularized). Many previous systematic eviews and meta-analyses have investigated outcomes following different surgicalÚpproaches, the use of vascularized versus nonvascularized bone graft for scaphoidßracture nonunions, and treatment for specific fracture patterns. However, given the advancements n scaphoid fracture treatment in recent years, there is a need for updated treatment recommendations hat would be beneficial to hand surgeons. Purpose: We present a comprehensive review of the operative treatment of scaphoid fractures based on recent literature and propose a unified treatment algorithm for managing these fractures. Methods: The English-language literature was searched from 2002 to 2023 for high evidence level (e.g., randomized trials), review, and meta-analysis articles with the following search terms: "scaphoid, "u8220"scaphoid" AND "nonunion, " and "scaphoid" AND "malunion. " Each article was creened by the authors to determine the scaphoid fracture scenario addressed and ubsequent treatment recommendations. The findings from article reviews were then rganized by scaphoid fracture types in this manuscript. Results: A total of 95 pertinent articles were ultimately selected and used as the basis for reviewing different scaphoid fracture scenarios. A treatment algorithm was then proposed based on literature review. Conclusion: This summary of the recent literature can guide hand surgeons in addressing scaphoidßractures. Future research in scaphoid fracture treatment, particularly for nonunions, would be most beneficial n the form of systematic review, meta-analysis, or multicenter prospective randomized clinical trials. Level of Evidence: IV.

Abstract
PURPOSE Scaphoid non-union treatment remains nonconsensual and is based on vascularized or non-vascularized bone grafting. This study aimed to evaluate with a long follow-up the functional, clinical, and radiological outcomes, reported complications and reoperations and studied non-union treatment prognostic factors. METHODS Patients who had undergone bone graft surgery for scaphoid non-union were retrospectively reviewed. The evaluated outcomes were pain, qDASH, PRWE and MWS scores, active range of motion, grip strength, union rate, scapholunate angle, carpal height, and presence of arthrosis. Complications and reinterventions were also reported. RESULTS This study included 60 scaphoid non-union treatments with a mean follow-up of 7.7 (1.5-20.3) years. Twenty (33.3%) non-unions were located at the proximal pole, including 6 (10%) with preoperative avascular necrosis (AVN). Union occurred in 51 patients (85%). The functional, clinical, and radiological results were good. The complication rate was 21.3% and the reintervention rate was 16.7%. Subgroup union rate analysis found no difference if the non-union is localized in the proximal pole or if there is AVN. CONCLUSION With a representative sample of the population and a long follow-up, we have found a good union rate, clinical and functional results regardless of the treatment method chosen. Scaphoid non-union treatment is still controversial and more studies are needed to accurate indications of each graft according to the patient and non-union characteristics. LEVEL OF EVIDENCE IV Retrospective cohort study.

Abstract
INTRODUCTION In order to avoid Scaphoid Nonunion Advanced Collapse (SNAC) type osteoarthritis, which progressively affects the radial and midcarpal joints, several vascularized and non-vascularized grafting techniques have been described. Over the past decade, there has been growing interest in arthroscopic cancellous bone grafts for scaphoid nonunion. The aim of this novel prospective study was to assess the healing rate of scaphoid grafts under arthroscopy, and the prognostic factors for healing. MATERIAL AND METHODS This prospective study was carried out across 10 centers between September 2019 and April 2021, in patients aged 16 to 65. Scaphoid nonunion grafting was performed arthroscopically. Union was assessed on CT scans and displacement correction angles were measured preoperatively and then at 3 and 6months. We assessed mobility, Jamar wrist strength, functional results as per the Patient Related Wrist Score (PRWE) and the Quick Disabilities of the Arm, Shoulder and Hand (Quick DASH) score. Risk factors for nonunion were assessed. RESULTS We included 77 patients with a mean age of 24years (18 to 55years) with a mean time between trauma and treatment of nonunion of 34.8months (6 to 180months). The population was represented by 46 manual workers and 20 were smokers. In 42 cases, the nonunion was proximal, in Schernberg zone I or II. At the last follow-up of 12.9months on average (Standard Deviation: 8.7months), union was achieved in 72 patients (93.5%). The average duration of union was 3.4months (Standard Deviation 1.6). Among the 5 patients who did not heal, grafting was performed in addition to the fixation. We did not identify any contributory factors for nonunion. CONCLUSION This study demonstrated the effectiveness of arthroscopic treatment of scaphoid nonunion with a union rate at least equivalent to pedicled vascularized grafts. Smoking and delayed treatment were no longer considered unfavorable prognostic factors in the context of arthroscopic treatment. LEVEL OF EVIDENCE III.

Abstract
Background: This study assesses the variability of the palmar radiocarpal artery (PRCA), dorsal carpal branch of the ulnar artery (DCBUA), and anterior interosseous artery (AIA) in superselective catheter angiographies of the wrist (SCAW). Methods: Secondary analysis of consecutive SCAW (2009-2011). Measurements of the distances of the PRCA to the midface of the radiocarpal joint, the DCBUA to the styloid process of the ulnar, and maximum diameters of PRCA, DCBUA, and AIA. Results: Seven female and ten male patients (mean 35 years) received SCAW. All patients suffered from Kienbock's disease. The mean distance from the PRCA to the radiocarpal joint was 7.9 ± 2.3 mm and the distance from the DCBUA to the styloid process of the ulna was 29.6 ± 13.6 mm. The mean maximum diameter of the PRCA was 0.6 ± 0.2 mm, that of the DCBUA was 1.1 ± 0.4 mm, and that of the AIA 1.2 ± 0.3 mm. In six cases (35%), all three arteries contributed to the PRCA; in eight cases (47%), the radial and AIA; in two cases (12%), the radial and ulnar artery; and in one case (6%), only the radial artery contributed. Conclusions: SCAW are feasible to assist in preoperative planning. Os pisiforme transfer with DCBUA might be the best choice for a vascular bone graft in Kienbock's disease.

Abstract
BACKGROUND The aim of this study was to assess residual humpback deformity after arthroscopic treatment of scaphoid non-union. MATERIAL AND METHOD We reviewed the medical records of 47 patients with scaphoid non-union who underwent arthroscopic treatment between 2012 and 2018. Patients who did not receive an intraoperative bone graft were excluded (10 patients), as were those who did not achieve bone union (three patients). The radiographic assessment consisted of pre- and postoperative radiographs and CT-scans. RESULTS The radiolunate angle, scapholunate angle and Youm index were measured. At the final follow-up, the scapholunate angle was 54±8̊ (36-80̊) and the radiolunate angle was 11±7̊ (2-45̊). The scapholunate angle was significantly different between the preoperative measurement and the last follow-up; however, the radiolunate angle and Youm index did not change significantly. CONCLUSION Our study found that arthroscopic treatment of scaphoid non-union with a cancellous bone graft taken from the distal radius results corrects the humpback deformity. LEVEL OF EVIDENCE IV.

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
OBJECTIVES This study aims to compare the functional and radiological outcomes of the patients with scaphoid waist nonunion treated with non-vascularized bone graft and vascularized bone graft options. PATIENTS AND METHODS Between January 2016 and February 2020, a total of 24 patients (22 males, 2 females; mean age: 30.6±9.4 years; range, 18 to 66 years) with scaphoid waist nonunion who were treated with vascularized or non-vascularized bone graft were retrospectively analyzed. Of these patients, eight were treated with iliac crest non-vascularized bone graft (IC-NBG), seven with vascularized free medial femoral condyle (MFC) graft, and nine with 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft (1,2-ICSRA-VBG). The grip strength, flexion, extension, radial deviation, ulnar deviation angles were measured and compared to the contralateral hand for functional outcomes. Union rates, the scaphoid height-to-length ratio, the lateral intrascaphoid angle (LISA) were evaluated for radiological outcomes. The Mayo Wrist Score, Visual Analog Scale (VAS) score, and Quick Disability of the Arm, Shoulder and Hand (Q-DASH) Questionnaire score were calculated. RESULTS Union was observed in seven (87.5%) patients after IC-NBG, in six (85.7%) patients after MFC bone graft and nine (100%) patients in the treatment group with 1,2-ICSRA-VBG. There were no statistically significant differences among the IC-NBG, MFC and 1,2-ICSRA-VBG groups in terms of the union rates, the scaphoid height-to-length ratio, VAS score, Q-DASH score, grip strength and flexion, ulnar deviation, radial deviation angles after surgery (p>0.05). However, extension was statistically lower in the MFC group than IC-NBG and 1,2-ICSRA-VBG groups after surgery. The Mayo score was better in the IC-NBG group than MFC and 1,2-ICSRA-VBG, indicating a statistically significant difference (p<0.05). CONCLUSION Based on our study results, we suggest to use IC-NBG for scaphoid waist nonunion as the primary procedure, as the union rates are comparable with the MFC and 1,2-ICSRA-VBG techniques and it has advantages such as shorter operation time, easier technique, no special experience requirement, and better functional outcomes.

Abstract
The decision regarding the use of vascularized bone grafting (VBG) or nonvascularized bone grafting for the treatment of scaphoid nonunion (SNU) needs guidelines based on patient- and fracture-specific risk factors. Historically, the presence of avascular necrosis was viewed as the primary indication for VBG; however, avascular necrosis is not the only indicator to determine whether VBG can improve our treatment of difficult SNU cases. The methods of detecting scaphoid avascular necrosis lack consensus and accuracy, limiting their use as decision-making tools. Additionally, many other preoperative risk factors for SNU surgery failure have been reported and require careful and standardized study, including the location of nonunion in the scaphoid proximal pole, the duration of nonunion, previous failed nonunion surgery, smoking, and fracture nonunion displacement or collapse. An appropriate study size and design are needed to determine the factors that guide the use of VBG or nonvascularized bone grafting to optimize the outcomes of SNU surgery.

Abstract
BACKGROUND The bone graft vascularized by the 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) placed on the scaphoid by a dorsal approach is a technique used to treat scaphoid nonunions with avascular necrosis of the proximal pole and without significant bone loss or carpus collapse. We present the results of patients treated with a volar rerouting of the 1,2 ICSRA graft under the tendons of the first extensor compartment to treat more distal scaphoid nonunions than the proximal pole. The aim of this study was to assess the clinical and radiological outcomes of patients operated with this technique with the hypothesis that it would allow to treat more distal nonunions than those of the proximal pole. PATIENTS AND METHODS This retrospective study involved patients treated by a volar rerouting of the 1,2 ICSRA graft for nonunions of the middle and distal thirds of the scaphoid. Assessments included clinical outcomes and radiological bone consolidation. QuickDASH and Mayo Wrist scores were computed. Range of motion and grip strength were evaluated for both the operated and the contralateral sides. RESULTS Nineteen patients were followed-up for 33 months (range: 6-75). Mean postoperative QuickDASH score was 10 (range: 0-45), and mean Mayo wrist score was 85 (range: 50-100). Flexion and extension, ulnar and radial deviations were statistically different between the affected and healthy sides (p<0,05). Consolidation was achieved in 17 patients (89%). DISCUSSION This technical modification allowed good functional outcomes and scaphoid consolidation. It expands the classic indications of the vascularized 1,2 ICSRA bone graft to more distal nonunions than the proximal pole. LEVEL OF EVIDENCE IV.

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
CASE A 52-year-old man sustained a radiocarpal dislocation with extrusion of the scaphoid proximal pole, which was completely detached from the soft tissue. To reduce the risk of avascular necrosis (AVN), treatment involved simultaneous anatomic reduction and internal fixation of the fracture and vascularized bone graft (VBG) for the scaphoid proximal pole. At 4 months, magnetic resonance imaging and 36 months of follow-up radiography showed a healed scaphoid and revealed no evidence of AVN in the scaphoid proximal pole. CONCLUSION If the risk of AVN is high, we recommend considering the combination of internal fixation and VBG for the fresh scaphoid fracture.

Abstract
» Optimal management of nonunions of the proximal pole of the scaphoid is controversial and dependent on many patient and pathophysiologic considerations. » If the proximal pole subchondral bone support is sufficient, options include open reduction and internal fixation, either alone or in combination with autologous nonvascularized or vascularized bone graft. » If the proximal pole is not salvageable, replacement with osteochondral autografts or osteochondral flaps is the only option for reconstruction of the native anatomy.

Abstract
PURPOSE The most challenging scaphoid nonunion is the unstable nonunion with humpbacked collapse coupled with an avascular proximal pole. Dorsal distal radius pedicled vascularized bone grafts (VBGs) are contraindicated in cases of humpback deformity. The free medial femoral condyle VBG is an excellent option but it is an extensive microsurgical procedure with lengthy operative times and dual-limb incisions. In search of a local, volar, vascularized source of bone to treat this challenging subset of scaphoid nonunions, we analyzed our results with a volar distal radius bone graft based on the pedicled palmar radiocarpal artery (PRCA). METHODS A prospective cohort of 15 unstable nonunions with avascular proximal pole fragments was treated with the PRCA graft and open reduction internal fixation. Preoperative carpal indices revealed a high degree of instability. All 15 lacked punctate bleeding from the proximal pole. All 15 patients were treated with the PRCA VBG technique and scanned with computed tomography at approximately 6 and 12 weeks to assess for interval healing. RESULTS All nonunions healed with an average cross-sectional trabeculation score of 70% at week 6 and 84% at week 12. Sagittal intrascaphoid angles improved from 50° to 27°, radiolunate angle improved from -20° to -7°, scapholunate angle improved from 86° to 64°, and revised carpal height ratio improved from 1.45 to 1.53, indicating correction of the humpback collapse deformity. Patients were observed an average of 22 months to have no sign of further avascular necrosis. CONCLUSIONS Pedicled PRCA-VBG successfully addresses the dual needs of the humpbacked scaphoid nonunion with an avascular proximal pole while simultaneously limiting dissection to one limb and avoiding the additional complexities of free tissue transfer. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.

Abstract
Scaphoid nonunion is a challenging situation for orthopaedic surgeons. Nonunion rate is especially high in proximal pole fractures of the scaphoid due to tenuous retrograde blood supply.The use of pedicled vascularized bone grafts for the treatment of scaphoid nonunion provides both good clinical and radiological outcomes.The preserved vascularity of the graft leads to better bone remodelling, less osteopenia, faster incorporation and better maintenance of bone mass compared to the conventional non-vascularized grafting.Pedicled vascularized bone grafts also allow the correction of the carpal alignment and humpback deformity of the scaphoid.Clinical and radiological results have been satisfactory and promising, making us anticipate that the role of vascularized bone grafting for the treatment of carpal diseases will increase.

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.

Abstract
PURPOSE The aim of the present study is to present the long-term efficacy of the graft of the distal radius based on the 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) for the treatment of scaphoid nonunion with a proposed treatment of double stabilization with Kirschner wires and external fixator. METHODS Between 2007 and 2013 we retrospectively reviewed 11 patients who were operated for established scaphoid nonunion with pedicled vascularized distal radius graft based on the 1,2 ICSRA in our department. Stabilization of the graft was achieved with Kirschner wires and the wrist was immobilized with a transarticular external fixator. All patients were evaluated pre- and post-operatively both clinically and radiologically. The DASH score was also completed by the patients before and after the operation. The minimum follow-up of the patients was 5 years. RESULTS The mean age of the patients was 28.64 years (range, 18-49 years). Ten patients were males (90.91%) and one female (9.09%). In all patients, union was achieved. The mean time of union was 11.2 weeks (range, 8-18 weeks). The mean follow-up was 61.32 months (range, 60-72 months). Compared to the contralateral hand there was noticed 14° lack in flexion and 18° in extension. The mean DASH score showed also significant improvement from 23.1 (range, 9.4-50.6) preoperatively to 4.72 (range, 0-22.8) during the last follow-up. CONCLUSION The 1,2 ICSRA distal radius graft consists a trustworthy pedicled vascularized graft for the treatment of nonunion presenting very promising long-term outcomes.

Abstract
The most important goals of scaphoid reconstruction in pseudarthrosis are correction of the humpback deformity, the realignment of the proximal carpal row and the bony union of the scaphoid. Therefore, in most cases bone grafting is required. To increase the healing rate and to improve vascularization, several kinds of vascularized bone grafts have been developed. Pedicled grafts are preferably harvested from the dorsal or palmar side of the distal radius with fusion rates between 27% and 100%. Free microvascular grafts can be obtained from the iliac crest and the medial or lateral femoral condyle with fusion rates between 60% and 100%. For their application microsurgical equipment and skills are required. Up to now osteochondral grafts from the femoral condyle offer the only chance for joint surface replacement by transferring part of the surface of the femoropatellar joint. The use of vascularized grafts is still a matter of controversy, since their superiority is still unproven compared to nonvascularized grafts, which also achieved 100% fusion rates in several series. They are indicated in secondary procedures after failed reconstruction and nonunion with small avascular proximal pole fragments. Since no evidence-based guidelines exist, this article provides an experience-based treatment algorithm for scaphoid nonunion with special consideration to vascularized bone grafts.

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
In this retrospective study, we report the preliminary results of a novel technique for volar vascularized strut grafting to treat avascular scaphoid nonunion by using the 1,2 intercompartmental supraretinacular artery through a single incision. Forty-three of 45 patients with avascular scaphoid nonunion healed at a mean of 13 weeks (range, 3 to 10 mo). Complications consisted of 1 pin tract infection that resolved with oral antibiotics and 4 cases of transient dysesthesia of the radial sensory nerve. In 4 patients with equivocal radiographs, computed tomography scans confirmed bony union. The 2 patients who remained unhealed subsequently underwent proximal row carpectomy. Two other patients had persistent pain with the progression of radiocarpal arthritis. Our technique provides good results for the treatment of avascular scaphoid fracture nonunion. Notable advantages include performance through a single incision, use of an already established vascularized bone graft, volar graft placement, and no requirement for microvascular free graft reconstruction. It also provides the surgeon with the ability to adjust the procedure intraoperatively in the event of unexpected avascularity, without requiring substantially longer operative time or additional equipment.

Abstract
Background Vascularized bone grafts have become one of the first treatment options for scaphoid nonunions and Kienböck's disease. The aim of this study is to review the current body of the literature regarding the use of four vascularized bone grafts (1,2 ICSRA [1,2 intercompartmental supraretinacular artery] graft, 4+5 ECA [4+5 extracompartmental artery] graft, volar radial graft, and free medial femoral condyle graft) in these pathologies. Patients and Methods A search on MEDLINE and Google Scholar was performed. Exclusion criteria included language other than English, studies with no full text available, case reports, letters, editorials, and review articles. The primary outcomes included consolidation rate of the grafts and time to union regarding scaphoid nonunion, as well as the clinical outcomes (pain, grip strength, range of motion), revascularization of the lunate, and progression of the disease regarding Kienböck's disease. Results A total of 37 articles were included in the study enrolling 917 patients. Regarding scaphoid nonunion, the consolidation rate was 86.3% for the 1,2 ICSRA graft, 93.9% for the volar radial bone graft, and 88.8% for the free medial femoral condyle graft. In patients with Kienböck's disease, progression of the disease was observed in 13% of patients, and grip strength and pain were substantially improved whereas range of motion did not demonstrate statistically significant improvement ( p < 0.05). Conclusion Vascularized bone grafts yield successful outcomes in patients with scaphoid nonunions demonstrating a high union rate. In patients with Kienböck's disease, vascularized grafts lead to revascularization of the lunate in most of the cases with concomitant improvement of the clinical parameters.

Abstract
Treatment of scaphoid fractures has been focused mainly on achieving union, with less attention to restoring normal scaphoid shape and orientation. Malalignment of one carpal bone will disrupt the kinetics of the entire wrist. The dorsal intercalated segment instability deformity associated with scaphoid waist nonunion is a nondissociative form of carpal instability. It has to be reduced in the treatment of scaphoid waist nonunions to avoid kinetic problems that will lead to arthritic changes. Computerized tomography scanning has become indispensable to visualize the humpback deformity clearly. Different techniques may be used to restore the normal anatomy of scaphoid, from non-vascularized graft to arthroscopic bone grafting, and also the option of vascularized bone grafting.

Abstract
We did a meta-analysis of the literature in order to clarify which of the vascularized bone flaps (VBF) used for scaphoid non-union treatment has the best outcome with regard to various parameters. We analyzed 54 articles that present nine different types of VBF. The analysis concerned demographical patient information, radiographic parameters, fracture classification, including the presence or non-presence of avascular necrosis of the scaphoid proximal pole (PP AVN), parameters that have to do with the surgery itself and the postoperative protocol, the healing of the nonunion and functional scores. The meta-analysis showed best healing potential for the femoral graft despite the complexity of the operation. On the other hand, the most commonly used 1,2-ICSRA flap makes the procedure more reproducible but showed worse results. The femoral flap was also among the most successful flaps when used for patients with PP AVN. The consolidation rate, in general, was not affected by the time elapsed between the fracture and the operation but by smoking and the presence of PP AVN. The meta-analysis could not reach many significant statistical conclusions because of either the small number of patients in some flap groups or the heterogeneity and lack of documentation in most of the articles. © 2017 Orthopaedic Research Society.

Abstract
Background: The radiographic and clinical outcomes following vascularized bone grafting (VBG) for scaphoid nonunion have previously been reported in the literature; however, few studies report on patient-derived outcomes. The purpose of this study was to determine the effect of VBG for scaphoid nonunion on patient-derived outcomes. Methods: The MEDLINE and PubMed databases were queried for the use of VBG in scaphoid nonunion. We included studies that reported on patient-derived outcomes. We excluded studies with less than 10 patients or less than 6 months of follow-up. The primary outcomes assessed included functionality, percent and time to return to preinjury activity, postoperative pain, and patient satisfaction. Results: Twenty-six articles described the outcomes of 520 patients with an average of 19.3 patients per study. Functionality was most commonly assessed by the Mayo Modified Wrist Score and Disabilities of the Arm, Shoulder and Hand scores, which improved by 53.1% and 81.7% postoperatively, respectively. Within 16 weeks, 90.3% of patients returned to their previous occupation or sporting activity. Pain was most commonly reported using a 0 to 10 visual analog scale and improved 4-fold postoperatively. Complete satisfaction was reported by 92% of patients. The most common complications were superficial infections (1.56%), neuropathic pain (1.56%), and complex regional pain syndrome (1.25%). Conclusions: VBG for scaphoid nonunion results in the improvement of patient-derived outcomes, and high rates of return to preinjury activity levels and patient satisfaction. Multiple metrics of patient-derived outcomes were utilized by the studies in our review without a clear consensus as to which metric is most responsive and accurate.

Abstract
PURPOSE In an effort to improve fracture healing and decrease the need for autologous bone graft, products such as recombinant human bone morphogenetic protein (rhBMP-2) have been developed and used in both spine and nonspine surgery. There is a paucity of literature regarding the use of rhBMP-2 in scaphoid nonunion surgery with very little reporting on the complications associated with its use. The objective of this study was to retrospectively review the complications documented for a case series of patients treated with revision fixation, bone graft, and rhBMP-2 in revision scaphoid nonunion surgery. METHODS We retrospectively reviewed 6 cases of scaphoid nonunion revision surgery comprising open reduction and internal fixation (ORIF). All cases were performed for persistent nonunion after a previous scaphoid ORIF. All patients were treated with revision screw fixation, bone graft, and rhBMP-2. Union was determined by computed tomography in all cases. Complications of nonunion, heterotopic bone formation, delayed wound healing, functional loss of motion, and need for revision surgery are reported. RESULTS Between 2011 and 2014, 6 cases in which rhBMP-2 was used in revision scaphoid nonunion surgery were identified. All patients had failed an initial attempt at ORIF after delayed union or nonunion. The time from injury to index ORIF ranged from 3 months to 4 years (mean, 24 months). Revision surgery with rhBMP-2 was performed at an average of 6 months from the index ORIF. Of the 6 cases, 2 had resultant persistent nonunion. Both underwent scaphoid excision and midcarpal arthrodesis. Four cases developed notable heterotopic ossification (one of which required revision surgery). One patient had a loss of functional motion after the revision surgery. There were no cases of delayed wound healing. Only one of the 6 patients healed without complications. CONCLUSIONS In this case series, the use of rhBMP-2 in scaphoid nonunions was associated with a higher complication rate than reported in previous studies. Surgeons performing off-label use of rhBMP-2 should be aware of the potential for complications including heterotopic ossification. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Development of a Three-Dimensional (3D) Printed Biodegradable Cage to Convert Morselized Corticocancellous Bone Chips into a Structured Cortical Bone Graft. Int J Mol Sci 2016; 17:ijms17040595.

Abstract
This study aimed to develop a new biodegradable polymeric cage to convert corticocancellous bone chips into a structured strut graft for treating segmental bone defects. A total of 24 adult New Zealand white rabbits underwent a left femoral segmental bone defect creation. Twelve rabbits in group A underwent three-dimensional (3D) printed cage insertion, corticocancellous chips implantation, and Kirschner-wire (K-wire) fixation, while the other 12 rabbits in group B received bone chips implantation and K-wire fixation only. All rabbits received a one-week activity assessment and the initial image study at postoperative 1 week. The final image study was repeated at postoperative 12 or 24 weeks before the rabbit scarification procedure on schedule. After the animals were sacrificed, both femurs of all the rabbits were prepared for leg length ratios and 3-point bending tests. The rabbits in group A showed an increase of activities during the first week postoperatively and decreased anterior cortical disruptions in the postoperative image assessments. Additionally, higher leg length ratios and 3-point bending strengths demonstrated improved final bony ingrowths within the bone defects for rabbits in group A. In conclusion, through this bone graft converting technique, orthopedic surgeons can treat segmental bone defects by using bone chips but with imitate characters of structured cortical bone graft.

ACTA ACUST UNITED AC 2015; 34:32-8.

Abstract
Regardless of the treatment used, 25 to 45% of scaphoid fractures do not heal. Open surgery compromises vascularization and destabilizes ligament attachments. The aim of this retrospective study was to assess the value of retrograde percutaneous screw fixation of Alnot stage IIA and IIB scaphoid non-union in Schernberg zones 2 to 4. This series included 38 patients with a mean age of 31 years. Based on the Alnot classification, there were 16 stage IIA non-unions (12 in zone 3 and 4 in zone 2 according to the Schernberg classification) and 22 stage IIB non-unions (9 in zone 3 and 13 in zone 2). The time elapsed between the initial trauma and the surgical treatment was 10 months on average. Percutaneous retrograde fixation was performed with a cannulated 2.7mm compression screw. At 25 months follow-up, 31 of the non-union cases had healed (81.6%), of which 14 were stage IIA (87.5%) and 17 were stage IIB (77.3%), after an average 6.3 months. Average pain was 1.6. The average Quick DASH was 17.3/100. Compared to the opposite side, the average range of motion was 84.8% in flexion, 84.7% in extension, 98.9% in pronation, 96.5% in supination, 96.8% in ulnar deviation and 86.4% in radial deviation. The grip strength was 80.4% of the contralateral side. Seven patients did not heal after screw fixation; four of them healed after additional electromagnetic stimulation and three after addition of a vascularized bone graft. Based on this study's results, stage IIA non-unions can heal with simple retrograde percutaneous screw fixation. The same procedure could be enough for stage IIB non-union cases, however we recommend adding a cancellous bone graft by arthroscopy. Open surgery procedures are preferred when percutaneous procedures have failed.

Abstract
Scaphoid fractures that fail to unite are at risk of developing avascular necrosis and progressive structural collapse, thereby complicating attempts at revision surgical treatment. Vascularized bone grafts have demonstrated utility in promoting consolidation in the treatment of scaphoid nonunions complicated by avascular necrosis. Numerous pedicled and free vascularized grafts have been described with variable, but generally favorable, outcomes. Understanding the indications for different grafts is critical to the successful application of these techniques and grafts in the treatment of challenging scaphoid nonunions.
