Abstract
Background We observed several cases of heterotopic bone formation after a 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) distal radius vascularized bone graft (VBG) for the treatment of scaphoid nonunion. This adverse event seems underreported. Knowledge about factors associated with the formation of heterotopic bone after VBGs might help reduce this adverse event. Purpose What factors are associated with resected heterotopic bone formation after 1,2 ICSRA distal radius graft for the treatment of scaphoid nonunion? Patients and Methods We retrospectively reviewed all patients with a scaphoid nonunion treated with a 1,2 ICSRA distal radius graft between 2008 and 2019 in an urban level 1 trauma center in the Netherlands. We included 42 scaphoid nonunions in 41 people treated with the 1,2 ICSRA graft. We assessed potential correlation with patient, fracture, and treatment demographics. Results Heterotopic bone developed in 23 VBGs (55% [23/42]), of which 5 (12% [5/42]) were resected. Heterotopic bone was located radially (at the pedicle side) in all participants. Except a longer follow-up time ( p = 0.028), we found no variables associated with the development of heterotopic bone formation. Conclusion The location of the heterotopic bone at the pedicle site in all cases suggests a potential association with the periosteal strip. Surgeons might consider not to oversize the periosteal strip as a potential method to prevent heterotopic ossification after VBG. Level of Evidence Level II, prognostic study.

Abstract
Upper extremity reconstruction may pose clinical challenges for surgeons due to the often-critical, complex functional demands of the damaged and/or missing structures. The advent of vascularized bone grafts (VBGs) has aided in reconstruction of upper extremity (UE) defects due to their superior regenerative properties compared with nonvascularized bone grafts, ability to reconstruct large bony defects, and multiple donor site options. VBGs may be pedicled or free transfers and have the potential for composite tissue transfers when bone and soft tissue are needed. This article provides a comprehensive up-to-date review of VBGs, the commonly reported donor sites, and their indications for the treatment of specific UE defects.

Abstract
Background A malreduction or missed scaphoid fracture may lead to nonunion or avascular necrosis (AVN). The aim of this study was to analyze the radiological and clinical outcome of patients with scaphoid nonunion (SN), who were treated with 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft (1,2-ICSRA-VBG) fixed with K-wires or screws between 2014 and 2018. Methods Radiological assessment included posteroanterior, lateral, oblique, and angled posteroanterior projection. The wrist active joint range of motion was assessed with a universal goniometer, and grip and pinch strength with a dynamometer. The disabilities of the arm, shoulder and hand (DASH) questionnaire was used to evaluate functionality. Statistical analysis was performed using SPSS software (v16.0). Results A total of 68 patients (65 male) with a mean age 29.7 ± 8.5 years were evaluated in the study, and union was achieved in 55 (81%). A total of 45 (66%) patients had scaphoid waist fracture and 48 (71%) had AVN. Fixation was achieved with K-wires in 48 of the patients, and with screw in 20. The mean length of follow-up was 31.6 ± 14.6 (12-72) months. The mean radioulnar range of motion and DASH scores improved significantly after treatment ( p < 0.001, p ≤ 0.001). Conclusions The findings of this study showed that scaphoid unions can be treated successfully with high rates of union using the 1,2-ICSRA-VBG. This surgical technique requires special surgical experience. The functional outcome of patients improved after treatment, although smoking was found to be an important factor affecting functional results.

J Clin Med 2022; 11:jcm11123402. [PMID: 35743472 PMCID: PMC9225170 DOI: 10.3390/jcm11123402] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 06/09/2022] [Accepted: 06/13/2022] [Indexed: 02/06/2023] Open
Abstract
Background: Scaphoid fractures correspond to 60% of all carpal fractures, with a risk of 10% to progress towards non-union. Furthermore, ~3% present avascular necrosis (AVN) of the proximal pole, which is one of the main complications related to the peculiar vascularization of the bone. Scaphoid non-union can be treated with vascularized and non-vascularized bone grafting. The aim of the study is to evaluate the rates of consolidation of scaphoid non-union treated using two types of grafts. Methods: A systematic review of two electronic medical databases was carried out by two independent authors, using the following inclusion criteria: non-union of the proximal pole of the scaphoid bone, treated with vascular bone grafting (VBG) or non-vascular bone grafting (NVBG), with or without the use of internal fixation, patients aged ≥ 10 years old, and a minimum of 12 months follow-up. Research of any level of evidence that reports clinical results and regarding non-union scaphoid, either using vascularized or non-vascularized bone grafting, has been included. Results: A total of 271 articles were identified. At the end of the first screening, 104 eligible articles were selected for the whole reading of the text. Finally, after reading the text and the control of the reference list, we selected 26 articles following the criteria described above. Conclusions: The choice of the VBG depends mainly on the defect of the scaphoid and on the surgeon’s knowledge of the different techniques. Free vascular graft with medial femoral condyle (MFC) seems to be a promising alternative to local vascularized bone grafts in difficult cases.

Abstract
Fractures of the proximal scaphoid waist are more prone to nonunion than distal scaphoid fractures. Thirty-nine patients (five females, 34 males; mean age 31 years) who had operation for proximal scaphoid waist nonunion between 2017 and 2020 were retrospectively analysed. Patients received a free vascularized medial femoral condyle graft (Group 1: 18 patients) or distal radial bone graft based on a 1,2 intercompartmental supraretinacular artery pedicle (Group 2: 21 patients). In Group 1, union was achieved in 17 of 18 cases, with mean time to union of 13 weeks and mean operation time was 221 minutes. In Group 2, union was achieved in 19 of 21 cases, with mean time to union of 15 weeks and mean operation time was 100 minutes. The radiological and functional results of both groups were similar. We recommend a distal radial bone graft based on the 1,2 intercompartmental supraretinacular artery pedicle for proximal scaphoid waist nonunions since the operation is shorter, technically more manageable and requires less microsurgical experience.Level of evidence: III.

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
BACKGROUND Scaphoid nonunion involving the proximal pole with the presence of avascular necrosis is difficult to reconstruct. We aimed to determine the efficacy of surgical treatment of proximal pole scaphoid nonunion with avascular necrosis using a dorsal capsular-based vascularized distal radius graft. METHODS Between 2000 and 2018, 64 patients with established proximal pole scaphoid nonunion with avascular necrosis were treated using a dorsal capsular-based vascularized distal radius graft. This graft was harvested from the dorsal aspect of the distal radius with its dorsal wrist capsule attachment. Fixation of the scaphoid nonunion was performed with a small cannulated screw, followed by insertion of the vascularized graft into the dorsal trough at the scaphoid nonunion site. In the last 47 patients of this series, a micro suture anchor was placed into the scaphoid to augment graft fixation. RESULTS Union rate was 86% (55 of 64 scaphoid nonunions with avascular necrosis) at a mean time of 12 weeks. Persistent non-union was noted in eight patients and fibrous union in one patient. No patients developed donor site morbidity. No graft dislodgment was noted. There was significant improvement of the wrist functional outcomes at the final follow up. CONCLUSIONS The dorsal capsular-based vascularized distal radius graft is a safe and effective treatment in patients with scaphoid nonunion with avascular necrosis of the proximal pole. This pedicle vascularized bone graft is derived from a location that can easily reach the proximal third of the scaphoid avoiding microsurgical dissection or anastomosis.

Abstract
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
PURPOSE Aim of the present study was to evaluate the clinical, functional, and radiological outcomes of 1,2-intercompartmental supraretinacular artery (1.2-ICSRA) vascularized graft technique together with compression screw fixation for the management of scaphoid nonunions. METHODS A retrospective study was designed to evaluate the medical records of the 21 patients treated with 1,2-ICSRA vascularized graft for established scaphoid nonunion of the waist or proximal pole between 2015 and 2018. Seventeen patients who met the criteria were included in the study. The retrospectively analysed demographic parameters included age, gender, injured hand (dominant/non-dominant), aetiology of the injury, delay between injury and operation, initial treatments following the fracture, tobacco use, and background diseases that may affect healing (diabetes, vasculopathy etc.). Radiological and clinical examinations were routinely performed 2 weeks, 6 weeks, 3 months and 6 months after surgery and during the final follow-up. Postoperative clinical and functional outcomes at the latest follow-up were evaluated by measuring active wrist range of motion, grip strength, Turkish version of Quick Disabilities of the Arm, Shoulder and Hand Questionnare (Quick DASH) and Mayo Wrist scores and comparing them with preoperative values. RESULTS All 17 patients were male with an average age of 26.82 ± 4.08 years (range 20-35 years). The fracture site was located in the scaphoid waist and proximal pole in 5 (29.4%) and 12 (70.6%) patients, respectively. Avascular necrosis was observed in 13 patients (2 at the waist, 11 at the proximal pole). The mean follow-up duration was 18.88 ± 11.98 months (range 6-44 months). No graft extrusion occurred, and no other complication was observed in any of the patients. Amongst the 17 patients, 15 (88.2%) achieved union. The total wrist motions of patients were better postoperatively than preoperatively. However, only improvement in wrist extension was found to be statistically significant. Quick DASH and Mayo Wrist scores of the patients and grip strength were significantly improved postoperatively. CONCLUSION The 1,2-ICSRA vascularized graft technique together with compression screw fixation offers an easy and reliable option for the treatment of scaphoid nonunions with a high union rate and good functional and clinical outcomes. LEVEL OF EVIDENCE IV Therapautic.

Abstract
Background: Although vascularized bone grafting can effectively treat scaphoid nonunion, the optimal duration of the immobilization period after bone grafting is unclear. Therefore, we aimed to examine the difference in the union rate and range of motion between short and long immobilization periods and infer the optimal post-immobilization period after pedicled vascularized bone grafting for scaphoid nonunion treatment. Methods: A total of 23 wrists (21 men and 1 woman) with scaphoid nonunion treated using an intercompartmental supraretinacular artery pedicled vascularized bone graft were analyzed. We examined the difference in the union rate and range of motion between patients immobilized for less than 49 days (short immobilization group) and those immobilized for more than 49 days (long immobilization group). The range of motion of the wrist joint was measured before and after surgery. Patient outcomes were also assessed. Results: The overall union rate was 95.6%. A significant difference was found in postoperative extension and flexion between the two groups, but not in terms of the functional outcome. If the intraoperative fixation is solid, intraoperative proximal pole bleeding is confirmed, and the follow-up radiograph shows a normal healing process, we propose immobilization of the wrist for ≤ 7 weeks. Conclusions: The immobilization duration should depend on the solidity of intraoperative fixation and a satisfactory appearance on follow-up radiography: absence of a gap at the graft interface, surrounding lucency, or movement of the implant and displacement of the graft. If there are no signs of graft failure and fixation is solid, immobilization of the wrist for 7 weeks or less is recommended.

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
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
This study aimed to determine the outcome of free vascularized medial femoral condyle bone grafts in the primary treatment of scaphoid nonunions with scaphoid foreshortening or carpal collapse and intraoperatively documented avascular necrosis. Thirty-two patients (28 male, four female) met the inclusion criteria. Median time from injury to surgery was 70 weeks. Thirty of 32 patients healed at a median of 12 weeks. There was significant improvement from preoperative to postoperative lateral intrascaphoid angle, scapholunate angle, and radiolunate angle. Two scaphoids failed to unite; one patient underwent scaphoidectomy and four-corner fusion 15 months postoperatively after suffering a subsequent injury. Another patient underwent 1,2-intercompartmental supraretinacular artery-based vascularized bone grafting at 4 months postoperatively and then scaphoid excision with four-corner fusion 4 years later. The free vascularized medial femoral condyle bone graft restores scaphoid vascularity and architecture while promoting union in a subset of scaphoid nonunions that has historically been a clinical challenge. Level of evidence: IV.

Abstract
PURPOSE We retrospectively reviewed the results of 89 patients with proximal pole scaphoid nonunion, 58 with avascular necrosis, treated with a capsular-based vascularized distal radius graft. METHODS Seventy-one male and eighteen female patients with symptomatic nonunion at the proximal pole of the scaphoid were included in this study. No patient had a humpback deformity. In all patients, the vascularized bone graft was harvested from the dorsum of the distal radius and was attached to a capsular flap of the dorsal wrist capsule. After fixation of the scaphoid with a small cannulated screw, the graft was inserted press-fit into the scaphoid trough in the nonunion site. Supplementary fixation of the graft with a microsuture anchor into the scaphoid was used in 66 patients. RESULTS At a mean time of 12.3 weeks (range 6-24) after surgery, solid union was achieved in 76 of 89 patients (49 of 58 with avascular necrosis). Eleven patients had persistent nonunion and two fibrous union as determined by CT scan. Sixty-six of the patients with solid bone union were completely pain free, and ten complained of slight pain with strenuous activities. No donor site morbidity was observed. CONCLUSIONS The capsular-based vascularized bone graft from the distal radius is a reliable alternative technique for scaphoid nonunions. It is a simple and expedient harvesting technique without the need for a microsurgical anastomoses. The supplemental fixation with a microsuture anchor eliminates the risk of graft displacement.

Abstract
BACKGROUND Outcomes following revision surgery for scaphoid nonunions with osteonecrosis are guarded. We hypothesized that use of free vascularized medial femoral condyle (MFC) bone grafts can lead to healing of the nonunion, increase vascularity of the proximal pole, and restore scaphoid architecture, resulting in acceptable functional outcomes. METHODS We performed a retrospective review of 49 patients who were treated with an MFC bone graft, between May 2005 and September 2016, after prior failure of operative treatment for scaphoid nonunion. The mean time from the injury to the revision surgery with the MFC bone graft was 24 months, and the mean time from the prior, failed surgery was 15 months. Thirty-six of the 49 patients had had a prior bone graft procedure and 6 patients had had 2 previous surgical procedures for the nonunion. The initial internal fixation of the scaphoid fracture was with a scaphoid screw in 43 patients. All patients had documented osteonecrosis of the proximal pole at the time of our surgery. Carpal indices, time to union, pain scores, functional outcomes, and complications were recorded. RESULTS Forty-one (84%) of the 49 previously operated on scaphoid nonunions healed at a mean of 16 weeks (range, 9 to 31 weeks) after the MFC bone-grafting as confirmed on computed tomography (CT). Radiographs demonstrated significant improvement in carpal alignment following the surgery with the MFC bone graft. Comparison between preoperative and postoperative values showed a trend toward improved grip strength and no important change in total wrist range of motion. Subsequent procedures were performed in 29 patients, 21 of whom had planned Kirschner wire removal. All 24 patients in whom scaphoid union had been achieved and who were available for follow-up were able to work or attend school full-time, and 88% were satisfied or very satisfied with their wrist function. Age, smoking status, body mass index, time to surgery, and preoperative radiographic findings were not found to be significant predictors of failure. CONCLUSIONS MFC grafts increase vascularity and restore scaphoid architecture, promoting union in most patients with the combination of proximal pole osteonecrosis, carpal collapse, and failed prior scaphoid nonunion surgery. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
PURPOSE To review the incidence of union of patients with proximal pole scaphoid fracture nonunions treated using a 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) vascularized graft and a small compression screw. METHODS This is a retrospective case series of 12 patients. Calculations of the size of the proximal pole fragment relative to the total scaphoid were performed using posteroanterior view scaphoid radiographs with the wrist in ulnar deviation and flat on the cassette. Analyses were repeated 3 times per subject, and the average ratio of proximal pole fragment relative to the entire scaphoid was calculated. We reviewed medical records, radiographs, and computed tomography (CT) scans of these 12 patients. The CT scans that were performed after an average of 12 weeks were ultimately used to confirm union of the scaphoid fractures. One patient was unable to have a CT so was excluded from the final calculation. RESULTS All 11 (100%) scaphoid fractures that were assessed by CT were found to be healed at the 12-week assessment point. The mean proximal pole fragment size was 18% (range, 7%-27%) of the entire scaphoid. CONCLUSIONS The 1,2 ICSRA vascularized graft and compression screw was an effective treatment for patients with proximal pole scaphoid fractures. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Introduction Scaphoid non-union is a challenging and complex problem. Various methods have been proposed for the management of patients with scaphoid non-union and to reduce the risk of complications. In this study, our aim was to evaluate the clinical and functional outcomes of using a vascularized bone graft in the treatment of scaphoid non-union. Methods Patients with scaphoid non-union who underwent 1,2 intercompartmental supraretinacular artery pedicled vascularized bone graft between January 2005 and January 2011 were enrolled. The parameters assessed included clinical and functional outcomes, radiological measures, and potential risk factors. Results Forty-one patients were finally included. Thirty patients achieved union (73%) and 11 did not. Smoking was a significant risk factor for non-union after the surgery. In patients who achieved union, grip strength and radioulnar abduction were greater in comparison to that in patients who did not achieve union. Functional measures, including the Disabilities of Arm and Shoulder score and the Modified Mayo Wrist Score, improved in patients with scaphoid union. The scaphoid length also improved significantly postoperatively in these patients. Conclusion Surgical treatment of scaphoid non-union using vascularized bone graft led to a high union rate with good clinical and functional outcomes. Smoking is a risk factor for non-union, even with the use of a vascularized bone graft. Avascular necrosis was not associated with an increased risk for non-union.

Abstract
The reported results for the treatment of scaphoid nonunions with non-vascularized grafts are based on observational studies with a high variability in union rates from 38%-100% and time to union from 6-18 weeks, and there is also a lack of a standard classification. Meta-analyses and systematic reviews have been presented to better support conclusions from large pools of data (604 to 5246 cases), but their interpretation remains limited because of lack of uniformity in the studies analysed. Several authors have presented results from the Zaidemburg flap, with highly variable outcomes despite using the same technique; union rates have ranged from 27%-100% achieved between 6.5-19 weeks. Technical details that may be responsible for the discrepancies are discussed. There is a need for a validated prognostic classification system for scaphoid nonunions that can allow comparisons between outcome studies.

Abstract
UNLABELLED We followed 35 consecutive patients with scaphoid nonunions in a prospective longitudinal registry. All nonunions were treated with curettage, non-vascularized autogenous grafting and headless screw fixation. Preoperative magnetic resonance imaging, intraoperative bleeding points and histopathological analysis of cancellous bone in the proximal pole were recorded as measures of viability. Healing was categorized as ≥50% bony bridging on computed tomographic images in the plane of the scaphoid. Nine of 23 proximal poles demonstrated ischaemia on magnetic resonance imaging but none were interpreted as infarcted. Twenty-eight of 33 were found to have impaired vascularity as assessed by intraoperative bleeding. Fourteen of 32 demonstrated ≥50% trabecular necrosis and four of 33 demonstrated ≥50% tissue necrosis on histopathological analysis. Thirty of 33 demonstrated focal or robust remodelling activity. Despite pathological evidence of impaired vascularity in over half of the patients, 33 of the 35 scaphoids had healed by 12 weeks. We conclude that proximal pole infarction is decidedly rare and that vascularized bone grafting is seldom required. LEVEL OF EVIDENCE IV.

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
INTRODUCTION Conventional non-vascularized bone grafts as well as vascularized bone grafts are used to treat scaphoid non-union (SN). Due to limited available studies, the field of application using both grafts for SN still remains controversial. The aim of this study was to evaluate a treatment algorithm for the use of both vascularized versus non-vascularized bone grafts based on clinical outcomes and quality of life (QoL) to improve the level of evidence. MATERIALS AND METHODS Based on a retrospective cohort study, including 28 patients with vascularized and 45 patients with conventional bone grafts, functional parameters, radiological outcome, Mayo-wrist-score, and QoL by SF-36 were applied to statistically compare the outcome of these two techniques. RESULTS Time between last procedure or trauma and study group scaphoid reconstruction was almost double in the vascularized bone grafting group. Comparable union rates were achieved with vascularized as well as non-vascularized bone grafts. Significant differences were observed between both groups for grip strength and radial-ulnar active range of motion. Further functional outcomes, radiological outcomes as well as QoL were found similar for both techniques in patients with surgical union. DISCUSSION AND CONCLUSIONS In order to achieve comparable and appropriate treatment results, vascularized bone grafts are recommended for patients with delayed treatment, impaired scaphoid vascularity, and revision surgery. Even in preselected, complex cases, the results are comparable to conventional grafts, which are the basis for further patient education and approve the powerful role of surgical angiogenesis of vascularized bone grafts.

Abstract
OBJECTIVES To evaluate the safety and efficacy of the Ilizarov fine-wire compression/distraction technique in the treatment of scaphoid nonunion (SNU), without the use of bone graft. DESIGN This is a prospective study of 20 consecutive patients in one center. PATIENTS AND METHODS This study included 20 patients (19 males) with a mean SNU duration of 14.5 months. Four patients had proximal pole, 15 had waist, and 1 had a distal SNU. Patients with carpal instability, humpback deformities, carpal collapse, avascular necrosis, and marked degenerative change were excluded. Following frame application, the treatment comprises three stages: The frame is distracted by 1 mm per day until the radiographs show a 2-3 mm opening at the SNU site (mean 10 days); the SNU site is compressed for 5 days, at a rate of 1 mm per day, with the wrist in 15 degrees of flexion and 15 degrees of radial deviation; the wrist is then immobilized in the Ilizarov fixator for 8 weeks. RESULTS Radiographic (radiography and CT scan) and clinical bony union was achieved in all 20 patients after a mean of 90.3 days (70-130 days). All patients returned to their pre-injury occupations. Thirteen patients had excellent results, four good, and three fair, according to the Mayo wrist score. CONCLUSIONS In these selected patients, this technique safely achieved bony union without the need to open the SNU site and without the requirement of bone graft.

Abstract
Scaphoid fractures as frequently overseen injuries often result in scaphoid non-unions, that need to be treated to prevent carpal collapse and secondary cartilage damage. Vital bone tissue and compression of fracture and bone graft ends seem to be crucial in for ossification and final bone healing. In the present study we compare our results using a high compression screw (HCS Synthes®) to results in the literature using different kinds of internal fixation including compression screws of various types. We present 22 patients with scaphoid non-unions treated with a bone graft and a HCS Synthes®. We evaluated our post-operative results. The Manchester-Modified Disability of the Shoulder, Arm and Hand–Score (M-Dash) imposed with an average of 29.8 points (MD=29 / SD=9.46 / MIN=18 / MAX=48). None of the re-evaluated patients sorrowed for pain in rest. Five patients stated pain (ranging from 4 to 8 on numeric analogue scale) after heavy burden (e.g. boxing, weight lifting).In exploring the range of motion of the operated hand we deliver the following results: dorsal extension: average 72.73° (MD=80° / SD=17.23° / MIN=30° / MAX=85°), flexion: average 73.64° (MD=80° / SD=8.97° / MIN=60° / MAX=80°), ulnar deviation: average 39.09°, (MD=40° / SD=2.02° / MIN=35° / MAX=40°), radial deviation: average 29.09°, (MD=30° / SD=3.01° / MIN=20° / MAX=30°). Additionally a performance testing was conducted: fist clenching sign: complete without pain in 100%, pinch grip: complete in 100%, moderate pain in n=1 (8.33%), opposition digitus manus I–V complete in 100%, moderate pain n=2 (16.67%). Three patients with persisting fracture gap had a scaphoid bone fractured in the proximal third; one patient even with a very small proximal fragment. One persisting non-union was localized in the middle third (period between injury and operation = 5 years). In conclusion, our patients showed better healing rates compared to results presented in the literature. Non-unions localized in the proximal third of the scaphoid did not seem to benefit using this technique.

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
INTRODUCTION The main aim of this retrospective study was to present our experience on scaphoid nonunion treated with vascularised bone graft. METHODS Between 2006 and 2012, 58 patients presenting with symptomatic scaphoid nonunion were eligible to participate in this study. Topography of the nonunion included 29 proximal, 25 waist and 4 distal scaphoid nonunions. Vascularised bone graft from distal dorsal radius was used in all cases which were stabilised with the headless cannulated compression screws. Scapholunate angles, Natrass carpal height ratio were evaluated pre and postoperatively. Range of motion of the affected side was compared to that of the contralateral side after the surgery. RESULTS Radiographic union was achieved in 50, out of 58 cases with an average time of 9.9 weeks (range, 6-18 weeks). Out of all the non-united cases, four of them were in proximal, three in the waist and one was in distal scaphoid. In nine proximal nonunions treated by 4+5 ECA graft all but one were united. The mean follow up was 21.7 months (12-62 months). The flexion was 91.6%, the extension was 91.5%, the radial deviation was 81.2%, and the ulnar deviation was 89.5% compared to the other side. The grip strength was 93%. Preoperative DASH score was 61.5 diminishing to 28.7 postoperatively. There was no significant change in Natrass carpal height ratio but a slight improvement occurred in scapholunate angles both pre and postoperatively. CONCLUSION Vascularised bone graft is a good solution for scaphoid nonunion to enhance the healing rate especially in the presence of avascular necrosis. Proximal pole nonunions, humpback deformity and smoking are important negative factors for scaphoid nonunion despite the use of a vascularised bone graft. A trapezoidal wedge graft is necessary for the volar type nonunions with humpback deformity. 1,2 ICSRA offer an advantage with its proximity to scaphoid in all nonunion locations. Nonetheless, 4+5 ECA graft is also a good solution for proximal nonunions.

Abstract
BACKGROUND Vascularized bone grafts of the hand are a promising option for treatment of hand abnormalities. Therefore, the purpose of this study was to analyze the arterial anatomy of the dorsal aspect of the second metacarpal base to further investigate this possible donor site for bone grafts. METHODS The authors examined 16 fresh frozen cadaveric hands by using a C-arm cone beam computed tomography scanner and depicted the three-dimensional course of the second dorsal metacarpal artery and measured the diameter, length, and arc of rotation of this nutritive vessel. In addition, the authors dissected six of the hands under a dissecting microscope and, after selective injection of gelatin dye solution, the authors analyzed the vessel entrances into the bones histologically. RESULTS In all examined hands, the second dorsal metacarpal artery was a nutritive vessel to the dorsal base of the second metacarpal. The average diameter was 1.3±0.4 mm and the average length of the vascular pedicle was approximately 3.3±0.3 cm. In 14 of 16 cases, the arc of rotation was sufficient to reach the lunate without difficulty. Histologic analysis showed an intrinsic blood supply in the donor region with a vessel diameter of approximately 58 μm. A clinical case with application in Kienböck disease is presented. CONCLUSION Pedicled vascularized bone grafts from this area are suitable for clinical application to treat Kienböck disease if standard donor sites are unavailable.

Abstract
PURPOSE To determine the outcome of an alternative treatment for wrists with stages I to III scaphoid nonunion advanced collapse using a closing-wedge osteotomy of the distal radius and a vascularized bone graft for scaphoid reconstruction. METHODS Twelve patients with scaphoid nonunion advanced collapse (stage I, 3; stage II, 7; stage III, 2) treated with a vascularized bone graft interposition for the scaphoid and a closing-wedge osteotomy for the distal radius were retrospectively reviewed. Data were obtained and analyzed from the radiographs, and we assessed the pre- and postoperative range of motion, grip strength, visual analog scale pain score, as well as the Mayo and Disabilities of the Arm, Shoulder, and Hand (DASH) functional scores. RESULTS Follow-up ranged from 2 to 11 years. All scaphoid nonunions united after an average of 9 weeks, and all osteotomies united after an average of 8 weeks. Although there was radiographic progression of the scaphoid nonunion advanced collapse stage in 5 of 12 cases, there was major improvement in visual analog scale pain score (from 6.1 to 0.8) and in both Mayo (from 64 to 85) and DASH (from 40 to 9) functional scores. The range of motion remained unchanged, and grip strength trended toward minor improvement. The carpal height was preserved, and the dorsal intercalated segmental instability was corrected. CONCLUSIONS Scaphoid reconstruction with vascularized bone graft combined with closing-wedge distal radius osteotomy preserved wrist function for scaphoid nonunion advanced collapse. The method offers pain relief and does not compromise wrist motion or grip strength. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
OBJECTIVES To compare the radiographic and functional outcomes of 2 surgical techniques for treating scaphoid nonunion. DESIGN Randomized prospective study. PATIENTS/PARTICIPANTS Researchers assessed the outcomes every 2 weeks until bone healing and at discharge. INTERVENTIONS (1) Vascularized bone grafting (VBG) using the 1, 2 intercompartmental suprareticular artery and (2) a distal radius nonvascularized bone graft. MAIN OUTCOMES/INTERVENTIONS Time to union (primary), union rate, and functional outcomes. RESULTS Seventy-five patients were followed for 29 months; 2 were lost to final follow-up. Both groups had similar baseline characteristics. The VBG group reached bone union earlier by 12 days (P = 0.002), but union rates were similar (P = 0.312). There was also less ulnar deviation in the VBG group (P = 0.03). There were no other differences between either intervention groups. CONCLUSIONS Although the VBG group attained earlier union, this may not be clinically meaningful, nor justify the greater technical difficulty and use of resources associated with this intervention. LEVEL OF EVIDENCE Therapeutic Level II. See instructions for authors for a complete description of levels of evidence.

Abstract
PURPOSE To evaluate the clinical outcome of 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft for scaphoid nonunion (SN). METHODS A retrospective study was performed to evaluate patients with SN and treated with 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft between 1997 and 2010. Functional measures, quality of life by Short Form SF-36 questionnaire, and analysis of risk factors were included. RESULTS Out of 39 patients who were eligible for the study, 11 were lost to follow-up. Out of the remaining 28 patients, union was achieved in 21 (75%). The mean length of follow-up was 63 ± 45 months. In hands with scaphoid union, the grip strength and the radioulnar active range of motion were less than the contralateral side but greater compared with patients with nonunion. Active extension-flexion was less compared with the noninjured hand but similar to patients with nonunion. Disabilities of the Arm, Shoulder and Hand (DASH) score decreased from 58 to 23 in dominant hands and from 46 to 13 in nondominant hands. Smoking was found to be a risk factor for nonunion. Patients with scaphoid union tended to higher scores in 8 domains of SF-36-Item Health Survey quality of life without significant difference. CONCLUSIONS Surgical treatment of SN with 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft provided a union rate comparable with other vascularized bone graft techniques. Previous scaphoid reconstruction with standard iliac crest bone graft was not associated with higher risk for secondary nonunion. There was an upward tendency seen in DASH score and quality of life after scaphoid union. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
OBJECTIVE To analyze the results of treatment of scaphoid nonunion with questionable viability of the proximal fragment, but without significant deformity or collapse, using a vascularized bone graft of 1,2 intercompartmental supraretinacular artery (1.2 ICSRA) and subsequent osteosynthesis. MATERIAL AND METHOD A retrospective study was performed on 10 male patients with a radiographic diagnosis of nonunion. Functionality, pain using Visual Analog Score (VAS), grip strength, patient satisfaction and reintroduction to working life, using QuickDASH and May specific wrist scales were assessed after the treatment. The integration of the graft was checked by radiography. RESULTS The mean follow-up was 31.4 months, and 90% of the questionnaires were satisfactory. The VAS decreased by 4.6 points and the flexor-extensor mobility gain was 5°. The total graft consolidation rate reached 40% in 5.5 months on average. DISCUSSION Several studies have demonstrated better results using vascularized bone graft versus non-vascularized. From the description by Zaidemberg in 1991, the vascularized graft with 1.2 ICSRA artery, distal radius, has been the most widely used for the treatment of scaphoid nonunion. CONCLUSIONS Our results are comparable with the literature reviewed, thus using vascular graft of the 1.2 ICSRA and osteosynthesis with Herbert-type screw, may be an alternative treatment for proximal scaphoid nonunion, without collapse or significant deformity.

Abstract
PURPOSE To investigate the outcomes of vascularized distal radius pedicled bone grafting secured with K-wires for scaphoid nonunions with small avascular proximal fragments. METHODS We included patients with scaphoid nonunions and small, avascular proximal fragments that were too small for screw fixation. The mean size of the proximal pole fragments was 21% (range, 9% to 28%) of the entire scaphoid, based on quantitative radiographic measurement. All patients had distal radius bone grafting based on the 1,2-intercompartmental supraretinacular artery pedicle and fixation with K-wires. There were 21 wrists in 18 men and 2 women with the mean age of 34 years (range, 22 to 57 y). The mean duration of postoperative follow-up was 40 months (range, 12 to 103 mo). Radiographic union and clinical outcomes, including the ranges of wrist motion, grip strength, and the modified Mayo wrist score, were evaluated. RESULTS Union was achieved in 18 of 21 wrists (86%) at a mean time of 14 weeks after surgery (range, 8 to 28 wk). Nonunions with proximal fragments less than 20% of the total scaphoid healed in 6 of 8 wrists. In a subset of these 8 wrists in which the proximal fragment was less than 15%, healing occurred in 2 of 4. The modified Mayo wrist score significantly improved from 46 to 78 points, and final wrist functions were rated as excellent in 5, good in 5, fair in 10, and poor in 1. Ranges of motion and grip strengths did not show significant changes after surgery. CONCLUSIONS Vascularized distal radius bone grafting and K-wire fixation can heal scaphoid nonunions with small avascular proximal fragments, although motion and grip strength remain unchanged. Healing may be related to the size of the proximal pole fragment.

Abstract
INTRODUCTION This is single centre retrospective review of a consecutive series of patients with scaphoid nonunion (SNU) treated using the Ilizarov technique without bone graft. Fifteen of the original 18 patients were available for clinical and radiological examination at a minimum follow-up of 5 years (range 5-10 years). An evaluation was made of the late functional results, satisfaction scores, residual symptoms, grip strength and the presence of radiocarpal and scaphoid degenerative changes. METHODS The series consisted of 15 patients; 14 males; 1 female, with a mean SNU duration of 15.7 months, and a mean age of 23.6 years. Patients with carpal instability, humpback deformity, carpal collapse, avascular necrosis or marked degenerative change, were excluded from this treatment method. Following frame application the treatment consisted of three stages: distraction, compression and immobilisation. The technique is detailed herein. RESULTS Radiographic (CT) and clinical bony union was achieved in all 15 patients after a mean of 88 days (70-130 days). Mean modified Mayo wrist scores initially improved from 21 preoperatively to 86 at previous review, and were 96 at a mean follow-up of 81 months (62-120 months), with excellent results in 10, and good results seen in 5 patients. At latest review the mean grip strengths had returned to 96% of the uninjured hand, and 7 patients had regained full strength; mean wrist flexion/extension arc of motion had also continued to improve to 136° from 131°. All patients returned to their pre-injury occupations and levels of activity at a mean of 117 days. Three patients suffered superficial K-wire infections, which resolved with oral antibiotics. One patient continues to suffer intermittent mild aching in the wrist. No patient suffered loss of scaphoid height, humpback deformity, DISI instability or collapse of the regenerate bone. CONCLUSION In these selected patients this technique safely achieved bony union without the need to open the SNU site and without the need for bone graft. These patients also had the capacity to continually improve their wrist function beyond 3 years following their treatment.

Abstract
Vascularized bone grafts from the distal radius have been used successfully for the treatment of scaphoid nonunions. Typically, the harvested graft is secured into the scaphoid with a press-fit technique. This type of fixation may lead to graft extrusion in the early postoperative period, and thus to treatment failure. In this technical note, we describe the use of micro bone suture anchors for supplemental fixation of the vascularized bone graft into the scaphoid. It is a simple and quick technique and provides an enhanced fixation of the vascularized bone graft, which is beneficial during the early critical period of bone healing.

Abstract
Scaphoid fractures are common and prone to nonunion if left untreated. In this study, the outcome of using a vascularized bone graft was investigated in scaphoid nonunion. Twenty patients with scaphoid nonunion were recruited from Shohada Hospital. A reverse-flow vascularized bone graft was obtained from the distal metaphysis of radius and inserted into the gap of scaphoid fracture. Long and short thumb spica casts were used for 1.5 and 2 months thereafter, respectively. Union, motion, pain and the patients' satisfaction rate were documented. Twenty patients, 19 males and 1 female, with a mean age of 25.15 +/- 6.62 (range: 17-40) years were studied. The fractured were in the waist of the bone in 17 cases and in the proximal pole in 3 cases. Preoperative pain and pain plus compromised grip strength were reported in 11 and 9 patients, respectively. The rate of patients with pain decreased significantly after operation (100 to 25%; p < 0.001). Complications happened in 7 patients (35%) after operation including pin fracture (n = 2), change of occupation (n = 2), nonunion (n = 1), delayed union (n = 1) and irritation (n = 1). Union achieved after 10.71 +/- 1.62 (range: 8-14) weeks in average, post-operation. Mayo wrist score improved significantly at the endpoint. The range of motion of the wrist did not change significantly after operation. Eighty percent of the patients rated the satisfaction rate as good to excellent. This study is the first one from a developing country indicating that the technique of using a reverse-flow vascularized bone graft in treating scaphoid nonunion is considerably successful and safe.

Abstract
INTRODUCTION The treatment of scaphoid non-union with non-vascularized bone graft leads to non-union in 10 to 20% of cases and up to 50% in case of proximal pole necrosis. Vascularized bone graft improves consolidation rates, but is generally restricted to secondary scaphoid non-union. HYPOTHESIS This study assessed the value of a primary vascularized bone graft pedicled on the transverse volar carpal artery from the volar aspect of the distal radius as donor site. PATIENTS AND METHODS This retrospective study included 111 cases of vascularized bone graft for scaphoid non-union as primary procedure in 73 cases and secondarily in 38. The procedures were performed through a single incision. RESULTS Mean delay before surgery was 25.5 and 33 months respectively, with union rates of 96% and 89.5%. Results showed improvement in both groups, but were better in primary surgery in terms of range of motion, strength, pain, function, satisfaction and return to work. There were more complications with secondary surgery. DISCUSSION All reports agree that union is better with vascularized bone graft. This technique performed as a day of admission surgery through a single incision under locoregional anesthesia seems feasible as a primary intervention.

Abstract
Objectives Evaluating the safety and efficacy of the Ilizarov fine-wire compression/distraction technique in the treatment of scaphoid nonunion (SNU), without the use of bone graft. Design A retrospective review of 18 consecutive patients in one centre. Patients and Methods 18 patients; 17 males; 1 female, with a mean SNU duration of 13.9 months. Patients with carpal instability, humpback deformity, carpal collapse, avascular necrosis or marked degenerative change, were excluded. Following frame application the treatment consisted of three stages: the frame was distracted 1 mm per day until radiographs showed a 2-3 mm opening at the SNU site (mean 10 days); the SNU site was then compressed for 5 days, at a rate of 1 mm per day, with the wrist in 15 degrees of flexion and 15 degrees of radial deviation; the third stage involved immobilization with the Ilizarov fixator for 6 weeks. The technique is detailed herein. Results Radiographic (CT) and clinical bony union was achieved in all 18 patients after a mean of 89 days (70-130 days). Mean modified Mayo wrist scores improved from 21 to 86 at a mean follow-up of 37 months (24-72 months), with good/excellent results in 14 patients. All patients returned to their pre-injury occupations and levels of activity at a mean of 117 days. Three patients suffered superficial K-wire infections, which resolved with oral antibiotics. Conclusions In these selected patients this technique safely achieved bony union without the need to open the SNU site and without the use of bone graft.

Abstract
INTRODUCTION We present a retrospective study on different treatment options for scaphoid nonunion. The results are compared to the literature and a treatment algorithm is proposed. MATERIALS AND METHODS Based on a retrospective case-control study, 208 patients suffering from scaphoid nonunion were treated between 2000 and 2006. The patients were grouped depending on the localization of the nonunion: proximal (n=10), middle (n=105), or distal (n=93) third. In the presence of a small avascular proximal fragment, a vascularized bone graft from the distal radius was added (n=53). The determination of scaphoid healing was achieved by conventional radiographs or CT scans. RESULTS Overall scaphoid healing occurred in 89.9% (n=187). For small proximal scaphoid fragments (n=93), we could show healing rates up to 83% (n=77). Using a vascularized bone graft from the distal radius, scaphoid consolidation was achieved in 81% for avascular proximal fragments and recurrent scaphoid nonunion (n=53). CONCLUSION Using sophisticated treatment options, the prognosis of scaphoid nonunions is very good.

Abstract
PURPOSE The purpose of this prospective study is to assess the diagnostic value of intravenously applied contrast agent for diagnosing osteonecrosis of the proximal fragment in scaphoid nonunion, and to compare the imaging results with intraoperative findings. MATERIALS AND METHODS In 88 patients (7 women, 81 men) suffering from symptomatic scaphoid nonunion, preoperative MRI was performed (coronal PD-w FSE fs, sagittal-oblique T1-w SE nonenhanced and T1-w SE fs contrast-enhanced, sagittal T2*-w GRE). MRI interpretation was based on the intensity of contrast enhancement: 0 = none, 1 = focal, 2 = diffuse. Intraoperatively, the osseous viability was scored by means of bleeding points on the osteotomy site of the proximal scaphoid fragment: 0=absent, 1 = moderate, 2 = good. RESULTS Intraoperatively, 17 necrotic, 29 compromised, and 42 normal proximal fragments were found. In nonenhanced MRI, bone viability was judged necrotic in 1 patient, compromised in 20 patients, and unaffected in 67 patients. Contrast-enhanced MRI revealed 14 necrotic, 21 compromised, and 53 normal proximal fragments. Judging surgical findings as the standard of reference, statistical analysis for nonenhanced MRI was: sensitivity 6.3%, specificity 100%, positive PV 100%, negative PV 82.6%, and accuracy 82.9%; statistics for contrast-enhanced MRI was: sensitivity 76.5%, specificity 98.6%, positive PV 92.9%, negative PV 94.6%, and accuracy 94.3%. Sensitivity for detecting avascular proximal fragments was significantly better (p<0.001) in contrast-enhanced MRI in comparison to nonenhanced MRI. CONCLUSION Viability of the proximal fragment in scaphoid nonunion can be significantly better assessed with the use of contrast-enhanced MRI as compared to nonenhanced MRI. Bone marrow edema is an inferior indicator of osteonecrosis. Application of intravenous gadolinium is recommended for imaging scaphoid nonunion.

Abstract
Vascularized bone grafts have been successfully applied for the reconstruction of bone defects at the forearm, distal radius, carpus, and hand. Vascularized bone grafts are most commonly used in revision cases in which other approaches have failed. Vascularized bone grafts can be obtained from a variety of donor sites, including the fibula, the iliac crest, the distal radius (corticocancellous segments and vascularized periosteum), the metacarpals and metatarsals, and the medial femoral condyle (corticoperiosteal flaps). Their vascularity is preserved as either pedicled autografts or free flaps to carry the optimum biological potential to enhance union. The grafts can also be transferred as composite tissue flaps to reconstruct compound tissue defects. Selection of the most appropriate donor flap site is multifactorial. Considerations include size matching between donor and defect, the structural characteristics of the graft, the mechanical demands of the defect, proximity to the donor area, the need for an anastomosis, the duration of the procedure, and the donor site morbidity. This article focuses on defects of the distal radius, the wrist, and the hand.

Abstract
Conventional bone grafts have some osteogenic potential, whereas vascularized bone grafts retain live, functional osteocytes and osteoblasts. High rates of scaphoid union have been achieved with conventional bone grafting in the absence of osteonecrosis or prior surgery. Vascularized bone grafting is valuable in the management of wrist disorders with compromised bone vascularity (eg, scaphoid nonunion with proximal pole necrosis, Preiser disease, Kienböck disease) or when previous grafting has failed. Improved understanding of the vascular anatomy of the wrist has allowed the use of an array of vascularized bone grafts that do not require microsurgical anastomosis. Successful outcome depends on careful patient selection and appropriate surgical technique.

Abstract
Pedicled bone and periosteal grafts provide successful reconstruction of skeletal problems of the distal radius, wrist, and hand. The purpose of this study was to evaluate the available alternatives and to propose the most suitable skeletal grafts for the reconstruction of the distal radius, and the carpal and hand bones. The alternative donor sites (dorsal and palmar distal radius, and metacarpals), their pedicles, and the potential coverage area in relation to specific wrist and hand pathology were determined in the cadaveric dissections. In the clinical setting, 75 pedicled grafts were used for the treatment of scaphoid nonunions (62 cases), lunate necrosis (8 cases), reconstruction of the metacarpal defects (2 cases), and wrist fusions (3 cases). All alternatives have the advantage of a single approach that may be performed under tourniquet control, from the same team. Among the available alternatives, surgeon's familiarity plays the most important role for the final selection of the graft.

Abstract
The aim of the present technical report is to describe the alternative solutions for the reconstruction of scaphoid nonunions with pedicled vascularized bone grafts from the distal radius. The surgical technique for the reconstruction A. of proximal scaphoid nonunions with pedicled bone grafts (based on the 1,2 or on the 2,3 intercomparmtental arteries) or with capsular bone grafts from the dorsal distal radius and B. of waist nonunions of the scaphoid with grafts from the palmar distal radius, pedicled on the palmar carpal arch, is presented. Vascularized bone grafts from the adjacent radius are used for the treatment of scaphoid nonunions to enhance union and to revascularize a nonviable proximal pole. The most suitable graft is selected according to the location of the nonunion (at the waist or the proximal pole of the scaphoid) and to the previous procedures/scars at the wrist level.

Abstract
PURPOSE Volar percutaneous screw fixation (PSF) of acute nondisplaced scaphoid waist fractures allows early mobilisation of the wrist and a faster return to work than prolonged cast immobilisation. Usually, placement of the wire which guides the definitive canulated screw is performed by hand. Nevertheless, correct placement of this wire is technically difficult. We designed a guidewire insertion device (GID) to facilitate this placement. METHODS We compared the hand held technique with the technique using the GID in a cadaveric study. The hand held technique was performed on 16 scaphoids and the GID was used in 16 other scaphoids. The four participating surgeons were divided into two groups: two experienced surgeons and two inexperienced surgeons. RESULTS The GID significantly decreased procedure duration (P<0.001), number of attempts to place the wire (P<0.001), and number of image-intensifier shots (P<0.001). With both techniques, experienced surgeons were significantly faster (P=0.0083) and required significantly fewer attempts (P=0.043) than inexperienced surgeons. Using the GID, the procedure duration (P=0.0039) and the number of image-intensifier shots (P<0.001) decreased more with inexperienced surgeons than with experienced surgeons. As for the number of attempts, there was no statistical difference between the two groups (P=0.32). CONCLUSIONS The GID decreased the time and radiation exposure needed to achieve correct volar percutaneous wire placement in the scaphoid, compared to the conventional hand held technique. Easier wire placement may lead surgeons to use PSF instead of prolonged cast immobilisation for treating nondisplaced scaphoid fractures.
