Abstract
Background Recalcitrant bone nonunion and osseous defect treatment is challenging and often requires vascularized bone transfer. The medial femoral condyle flap has become an increasingly popular option for reconstruction. The study aims at reviewing its different applications and synthesizing its surgical outcomes. Method A systematic review including all studies assessing surgical outcomes of free medial femoral condyle flap for bone reconstruction in adults was conducted on January 31, 2023. Flap failure and postoperative complications were synthesized with a proportional meta-analysis. Results Forty articles describing bony reconstruction in the head and neck, upper limb, and lower limb areas were selected. Indications ranged from bony nonunion and bone defects to avascular bone necrosis. Multiple flaps were raised as either pure periosteal, cortico-periosteal, cortico-cancellous-periosteal, or cortico-chondro-periosteal. A minority of composite flaps were reported. Overall failure rate was 1% [95% confidence interval (CI), 0.00-0.08] in head & neck applications, 4% in the lower limb (95% CI, 0.00-0.16), 2% in the upper limb (95% CI, 0.00-0.06), and 1% in articles analyzing various locations simultaneously (95% CI, 0.00-0.04). Overall donor site complication rate was 4% (95% CI, 0.01-0.06). Major reported complications were: femoral fractures (n = 3), superficial femoral artery injury (n = 1), medial collateral ligament injury (n = 1), and septic shock due to pace-maker colonization (n = 1). Conclusion The medial femoral condyle flap is a versatile option for bone reconstruction with high success rates and low donor site morbidity.

Abstract
INTRODUCTION Non-union is a prevalent complication of scaphoid fractures. Late diagnosis is common and has a clinical impact due to functional limitations for the patient. Multiple treatments have been proposed to manage this complication, ranging from conservative (i.e., orthopedic) to surgical treatment. The vascularized medial femoral condyle technique has shown satisfactory clinical and paraclinical results, mainly in presence of avascular necrosis of the proximal pole but data regarding functional outcomes and patient satisfaction is scarce. This case series aims to describe the clinical and patient-reported outcomes in a consecutive series of patients with non-union of the proximal third of the scaphoid treated with vascularized medial femoral condyle technique. METHODS Case series reporting results for a consecutive - initial cohort of patients who presented with a non united fracture of the proximal pole of the scaphoid, avascular necrosis of the proximal pole was documented by CT od MRI imaging preoperatively in all patients. Measurement instruments include the q-DASH and PRWE questionnaires, radiographic images, goniometry, and assessment of grip strength. RESULTS Twelve consecutive patients are included and they represent the initial cases for all surgeons involved; bone union was obtained in 10 patients (83%) after a mean follow-up time of 31 months (6-72), successful improvement in the range of motion and grip strength was documented. A high rate of satisfaction expressed by the patient was obtained, with an average score in Q-DASH of 17.3 and 20.1 in PRWE. CONCLUSIONS The vascularized medial condyle technique in cases of nonunion of scaphoid fracture is a reproducible treatment in clinical terms, both in imaging and functional terms, and in patient satisfaction. The learning curve is flat for a dedicated multi surgeon team.

Does indocyanine green fluorescence angiography impact the intraoperative choice of procedure in free vascularized medial femoral condyle grafting for scaphoid nonunions? Front Surg 2022; 9:962450. [PMID: 36117816 PMCID: PMC9478374 DOI: 10.3389/fsurg.2022.962450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 08/04/2022] [Indexed: 11/23/2022] Open
Abstract
Background Free vascularized medial femoral condyle (MFC) bone grafts can lead to increased vascularity of the proximal pole and restore scaphoid architecture in scaphoid nonunions. The intraoperative perfusion assessment of the bone graft is challenging because the conventional clinical examination is difficult. Indocyanine green (ICG) angiography has previously been shown to provide a real-time intraoperative evaluation of soft tissue perfusion in reconstructive surgery. The present study investigated the utility of ICG angiography in patients treated with a free medial femoral condyle graft for scaphoid nonunions. Methods We performed a retrospective analysis of patients with scaphoid nonunions, in which ICG angiography was used intraoperatively for perfusion assessment. The medical records, radiographs, intraoperative imaging, and operative reports of all patients were reviewed. Intraoperative ICG dye was administered intravenously, and laser angiography was performed to assess bone perfusion. The scaphoid union was examined using postoperative CT scans. Results Two patients had documented osteonecrosis of the proximal pole at the time of surgery. Four patients received a nonvascularized prior bone graft procedure, and a prior spongiosa graft procedure was performed in one patient. The mean time from injury to the MFC bone graft surgery was 52.7 months, and the mean time from prior failed surgery was 10.4 months. Perfusion of the vascular pedicle of the MFC and the periosteum could be detected in all patients. In two patients, even perfusion of the cancellous bone could be demonstrated by ICG angiography. Following transplantation of the bone graft, patency of the vascular anastomosis and perfusion of the periost were confirmed by ICG angiography in the assessed cases. No additional surgery regarding a salvage procedure for a scaphoid nonunion advanced collapse was necessary for the further course. Conclusion ICG-angiography has shown to be a promising tool in the treatment of scaphoid nonunion with medial femoral condyle bone grafts. It enables intraoperative decision making by assessment of the microvascular blood supply of the periosteum and the vascular pedicle of the MFC bone graft. Further studies need to evaluate the impact on union rates in a long-term follow-up.

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
BACKGROUND The purpose of this study is to compare the vascularized bone flaps (VBF) that are used in operations for scaphoid non-union in smokers and non-smokers and to scrutinize if the better biological potential of the VBFs can counteract the negative influence of smoking on healing. MATERIALS AND METHODS Our study included articles published until 2016, with scaphoid non-union patients who were operated on with a VBF or a VBG. RESULTS Eighteen articles met eligibility criteria with 335 non-smokers and 136 smokers totally. Healing of the scaphoid non-union was significantly more probable in the non-smoking group (OR=5.54, p<0.001). Patients with avascular necrosis in the proximal pole of the scaphoid (AVNPP) and non-AVNPP showed that non-smoking favors a better healing rate in both of these subgroups (p<0.001 and p<0.001, respectively). Non-smokers have 11 times and the non-AVNPP patient's 7.7 times greater probability of healing of the non-union. Meta-analysis of the data for time for healing showed a longer time in the smokers' group by 2.46 weeks, though non-statistically significant. The analysis could not prove that smoking is a predisposing factor for the development of AVNPP (spearman=0.094, p<0.05). Despite that, preoperative smoking cessation proved to be an inadequate healing moderator (OR=3.5, p=0.268). Finally, VBFs showed a significantly better healing rate compared with nVBGs in smokers (p=0.001). CONCLUSIONS A hand surgeon should always take into consideration that smoking negatively influences the healing potential of a scaphoid non-union despite the theoretically superior biological background that VBFs offer. In patients who refuse to quit smoking, a VBF may be considered a better choice than a conventional graft.

Abstract
BACKGROUND The free medial femoral condyle (MFC) bone flap is an attractive option for reconstruction of scaphoid nonunion utilizing vascularized bone to augment bony healing, especially in cases of failed prior treatment or osteonecrosis. This review aims to determine the role and reliability of the free MFC flap for treatment of scaphoid nonunion. METHODS A search of electronic databases was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles examining free MFC bone flaps for treatment of scaphoid nonunion were included for analysis. Outcomes of interest included flap failure, postoperative union rate, time to union, carpal indices, functional outcomes, and complications. RESULTS Twelve articles met the inclusion criteria. A total of 262 patients underwent free MFC flaps for treatment of scaphoid nonunion. The most common site of nonunion was the proximal pole of the scaphoid with 47% of patients receiving prior attempts at operative management. Overall bony union rate was 93.4% with a mean time to union of 15.6 weeks. There were no flap failures reported. Improvements in carpal indices including scapholunate (p < 0.0004), radiolunate (p < 0.004), lateral interscaphoid angles (p < 0.035), and revised carpal ratio height (p < 0.024) were seen postoperatively. Visual analog scale improved postoperatively from 6.5 to 2.3 (p < 0.015). Postoperative complications were observed in 69 cases (26.3%), with 27 patients (10.3%) requiring further operative intervention. However, no major donor or recipient site morbidity was appreciated. CONCLUSION MFC flaps provide a highly versatile and reliable option for reconstruction of scaphoid nonunion with excellent bony union rates and acceptable complication rates. The present literature suggests that MFC reconstruction of scaphoid nonunion restores radiocarpal anatomy and improves wrist function without causing significant donor or recipient site morbidity.

Abstract
INTRODUCTION We report our experience with use of the medial femoral trochlea (MFT) osteochondral flap for carpal applications. METHODS Outcomes of all patients treated with MFT flaps were reviewed. Healing, range of motion, grip strength, carpal alignment, pain, and complication data were collected. RESULTS MFT flaps were performed on seven patients with a mean age of 26.1 (range, 17-42) years. Indications included scaphoid proximal pole nonunion (n = 3), Kienböck's disease (n = 3), and Preiser's disease (n = 1). The mean follow-up was 32.3 (range, 5-70) months. Union was achieved in five patients at a mean of 12 (range 6-22) weeks. All five patients had increased grip strength and absence of pain at follow-up. There were two failures due to graft resorption. CONCLUSIONS The MFT osteochondral flap is a technically challenging yet powerful tool to replace the loss of both carpal articular cartilage and adjacent bone.

Abstract
PURPOSE To evaluate clinical and radiological outcomes after surgical treatment of difficult scaphoid nonunion in adults with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). MATERIALS AND METHODS Thirty-two patients at least 18 years old, with scaphoid nonunion and characteristics associated with a poor prognosis, who underwent a VTMPF procedure, were included in this retrospective cohort study with a mean follow-up of 17 months. Factors associated with a poor prognosis were a delay in presentation of over 5 years, the presence of avascular necrosis, and previous nonunion surgery. All patients had at least 1 poor prognostic factor and 25% had 2 or more. RESULTS In 30 men and 2 women, the mean age was 36 years (range, 19-56 years). There were 11 type D3 nonunions (Herbert classification) and 15 type D4. Five patients had delayed presentation of over 5 years. Fourteen patients had previously undergone an unsuccessful surgical attempt to treat their nonunion. The patients experienced no postoperative complications. Overall union rate was 97% (31 of 32 patients), with 72% cross-sectional trabecular percentage bridging at 12 weeks. Pain subsided after surgery and patients experienced improvements in both their Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Modified Mayo Wrist Score (MMWS). Overall 41% and 42% gains in strength and wrist motion, relative to the contralateral normal side, were observed. At final follow-up, there were no differences between the treated and the untreated (healthy) hands, in terms of wrist range of motion, grip, or pinch strength. CONCLUSIONS In this study, the use of VTMPF for difficult scaphoid nonunion in adults was associated with good general outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Since 2008 we have been using many free vascularized medial femoral condyle grafts for reconstruction of difficult scaphoid non-unions. This article aims to report our results and experiences. PATIENTS AND METHODS Until the end of 2019 a total of 287 patients had a microvascular scaphoid reconstruction, 158 with use of a corticocancellous, and 129 using an osseocartilaginous graft. Complete analysis of all of these patients was impossible. This manuscript is based on a retrospective analysis of 28 out of 42 patients with corticocancellous grafts operated on between 2008 and 2010 with a mean follow-up time of 6.1 years as well as another 44 out of 76 patients with an osseocartilaginous graft operated on between 2011 and 2016 with a mean follow-up time of 44 months. Follow-up included clinical parameters, conventional x-rays, a DASH-Score and a modified Mayo wrist score. Additionally, the authors report their personal experiences - necessarily without quantification. In view of this incomplete data-pool statistical analysis was not reasonable. RESULTS In the group with corticocancellous reconstructions bony healing was achieved in 69 %, salvage operations were required in 9,5 %. The 28 patients had a mean DASH-Score of 11, a mean modified Mayo wrist score of 83 points, a mean ROM of 86° and a mean grip strength of 89 % of the contralateral side. In the group with osseocartilaginous reconstructions complete bony healing was seen in 80 %, partial healing in 5 %, and salvage procedures were required in 11 %. The remaining 39 patients had a mean DASH-Score of 15, a mean modified Mayo wrist score of 80 points, a mean ROM of 90° and a grip strength of 81 % of the contralateral hand. A specific complication was an ossification of the pedicle, but the main problem was a satisfying reconstruction of the shape of the scaphoid and reestablishment of carpal stability in far advanced cases. We could not identify factors reliable for the persisting non-unions. CONCLUSIONS These operations combine great chances for healing with considerable risks for serious complications. So future patients have to be fully informed, so that their decision for such a procedure is based on realistic expectations.

Abstract
Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular.

Abstract
Vascularized small-bone grafting is an efficient and often necessary surgical approach for nonunion or necrosis of several bones in particular sites of the body, including scaphoid, lunate, distal ulna, and clavicle. The medial femoral condyle is an excellent graft source that can be used in treating scaphoid, ulna, clavicle, or lower-extremity bone defects, including nonunion. Vascularized bone grafting to the small bones, particularly involving reconstruction of damaged cartilage surfaces, should enhance subchondral vascular supply and help prevent cartilage regeneration. Vascularized osteoperiosteal and corticoperiosteal flaps are useful for treating nonunion of long bones.

Abstract
We report the case of a 23-year-old patient treated for a large giant cell tumour of the synovial sheaths of the ulnar edge of the hand and wrist invading the triquetrum, the hamatum, the ulnar part of the capitate as well as the bases of the 3rd, 4th and 5th metacarpals and the floor of the Guyon's canal and the carpal tunnel. A monobloc resection was performed in a healthy margin ; the loss of bone substance was 7×3.5cm. We performed a bone reconstruction using a cortico-cancellous medial femoral condyle free flap of 8×4cm. Postoperative follow-up was uneventful and bone consolidation was achieved at 2,5 months postoperatively. The cortico-cancellous medial femoral condyle free flap is an interesting option for treating small and medium size bone loss in the hand and wrist. Its use in its pure bone form or in its chimeric form with muscle, cartilage or skin opens up a wide range of choices for the reconstructive surgeon.

Abstract
The use of the medial femoral condyle free flap is a versatile option for the treatment of upper extremity non unions and reconstructive procedures associated with bone loss or osteonecrosis. The benefit of this type of flap is the viability of the bone which favors primary ossification and increases bone density. Vascularized free bone flaps are especially useful for the treatment of recalcitrant nonunions, or nonunions that have failed three or more treatments to obtain consolidation. We present a case series of three patients treated with medial femoral condyle free flap for reconstruction of the upper extremity of different etiologies at the level of the distal humerus, distal radius and distal phalanx of the thumb.

Abstract
Objective We hypothesized that lengthening the scaphoid in a model of scapholunate ligament injury (SLI) will result in correction of radiographic markers of dorsal intercalated segment instability (DISI) deformity. Materials and Methods An SLI with DISI deformity was created by sectioning the SL ligament, the palmar radiocarpal ligaments, and scapho-trapezio-trapezoid ligaments of a cadaveric upper extremity ( n = 5). The wrist was radiographed in both anteroposterior and lateral planes to confirm creation of SLI and DISI. The scaphoid was then osteotomized at its waist. A series of grafts (1-8 mm) were then placed at the osteotomy site. Radiographs were completed at each length. The main outcome measures were scapholunate interval (SL, mm), scapholunate angle (SLA, degrees), and radiolunate angle (RLA, degrees). These values, measured following the insertion of varying graft lengths, were compared with baseline measurements taken "post-injury" status. Results The ability to create an SLI with DISI was confirmed in the postinjury group with a statistically significant change in RLA, SLA, and SL compared with preinjury. With osteotomy and progressive insertion of spacers, the values improved into the accepted normal ranges for RLA (6 mm) and SLA (4 mm) with scaphoid lengthening. Conclusions In this cadaveric model of SL injury, radiographic markers of DISI were returned to within normal ranges with scaphoid osteotomy and lengthening. Clinical Relevance The results of this study add insight into wrist kinematics in our injury model and may represent a potential future direction for surgical treatment of SLI.

Abstract
Surgical strategies for scaphoid nonunions become more complex based on time from injury to treatment. The decision-making process, however, can follow a logical sequence. Scaphoid nonunions less than 1 year after trauma and no carpal malalignment can be treated with percutaneous screw fixation under fluoroscopic and/or arthroscopic guidance. Reinterventions or patients with avascular proximal poles that do not need substantial grafts are reliably treated with pedicle vascularized bone grafts. Resection of the distal pole of the scaphoid is a good option in old nonunions or after a failed scaphoid procedures. When there are radioscaphoid degenerative changes, salvage procedures such as proximal row carpectomy (PRC) should be considered.

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
BACKGROUND Vascularized bone grafts from the medial femoral condyle (MFC) are used to gain surgical revascularization of osseous defects. To date objective data regarding the donor site morbidity are limited. This study aims to evaluate the donor site associated outcome after MFC flap harvest. PATIENTS AND METHODS From 2008 to 2016, 22 patients who underwent MFC bone flap harvest for osseous revascularization of 9 talus, 8 scaphoids, 2 metacarpals, 1 phalanx, 1 pilon tibiale, and 1 distal femur were included. Outcome analysis was performed for the whole cohort as well as for two subgroups (recipient site upper [group A] and lower extremity [group B]) by the lower extremity functional scale (LEFS), the OAK-score of the Swiss Orthopedic Society and the visual analog scale (VAS). Additionally, a 3D gait analysis was performed for four patients. RESULTS The mean flap size was 1 × 1 × 3 cm. No flap loss was observed. One minor surgical revision was performed due to donor site hematoma. Mean follow-up was 35.8 (12-98) months. Mean LEFS-score was 74.9 ± 9.5 (A: 74.3 ± 7.9; B: 75.6 ± 11.2, p > .05) and OAK-score was 92.8 ± 9.4 (A: 93.2 ± 5.8; B: 92.4 ± 12.3, p > .05). At follow-up examination, pain at rest was stated with 0.1 ± 0.2 (A: 0.1 ± 0.3; B 0 ± 0, p > .05) and with activity 0.6 ± 1.4 (A: 1.2 ± 1.8; B: 0 ± 0, p > .05) on VAS. The 3-D gait analysis showed normative walking patterns. CONCLUSION After MFC flap harvest knee function and gait pattern were almost unimpaired. Donor site morbidity can be considered as being of minor concern in the decision-making for this microvascular procedure.

Abstract
PURPOSE Currently, there is no consensus on the optimal treatment for scaphoid nonunion with avascular necrosis (AVN). Various techniques, often involving vascularized corticocancellous bone grafting, have been proposed. The authors hypothesized that similar outcomes might be possible with volar plate fixation augmented with autogenous pure cancellous graft. METHODS The authors performed a retrospective chart review of 13 cases of scaphoid nonunions with AVN in 12 patients treated with plate fixation and pure cancellous bone grafting. Surgical management included a volar incision, reduction, impaction of cancellous bone graft from the ipsilateral olecranon and/or distal radius, and application of a volar locking plate. Postoperative outcome measures included time to union based on computed tomography, patient-reported pain and disability scores, grip strength, range of motion, and return to work and sports. RESULTS The average patient was 32 years old (range, 17-50 years) and treated an average of 18 months after initial injury (range, 6-49 months). Two of 12 patients (15.7%) were female, 3 of 12 patients (25%) were smokers, and 5 of 12 patients (41.7%) had failed union with previous screw fixation. Twelve scaphoids (92.3%) were treated for AVN associated with a proximal pole fracture, and 1 (7.7%) for AVN proximal to a scaphoid waist fracture. Mean follow-up was 19.5 months (range, 12-29 months). Union was achieved in all patients. Two scaphoids (15%) achieved union by 12 weeks, 7 scaphoids (54%) by 18 weeks, 2 scaphoids (15%) by 24 weeks, and 2 scaphoids (15%) by 30 weeks (range, 8.9-28 weeks). Mean Disabilities of the Arm, Shoulder, and Hand score improved from 30.6 ± 6.2 before surgery to 17.2 ± 6.5 after surgery. All 11 employed patients returned to work, although 3 (27.2%) did not return to full capacity. CONCLUSIONS Scaphoid plate fixation and pure nonvascularized cancellous bone grafting for scaphoid nonunion with AVN yields excellent union rates and good patient-reported and functional outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Nonvascularized bone grafting (NVBG) and vascularized bone grafts (VBGs) have been used to treat scaphoid nonunions. A comparison of a single institution' s experience using structural iliac crest bone graft (ICBG), 1,2-intercompartmental supraretinacular artery (1,2-ICSRA), and medial femoral condyle (MFC) grafts to treat scaphoid nonunions was undertaken. METHODS Thirty-one patients underwent ICBG, 33 patients underwent 1,2-ICSRA, and 45 patients underwent MFC grafting. Mean time to follow-up was 16 months (range, 2-153). Twenty-three percent used tobacco products. Mean age was 24 years (range, 11-66), with 86% male patients. Outcomes included union rate, time to healing, range of motion, complications, and reoperations. RESULTS Union rates and mean time to union were 71% and 19 weeks for the ICBG group, 79% and 26 weeks for the 1,2-ICSRA group, and 89% and 16 weeks for the MFC group, respectively. Failure of union was associated with tobacco use but not with age, gender, time from injury to surgery, or type of fixation. There was no significant difference between the groups regarding range of motion or strength. CONCLUSIONS These findings demonstrate the need for careful patient selection. In patients with the most complicated scaphoid nonunions (avascular necrosis, carpal collapse, and previous surgeries), the MFC group had the highest union rate and fastest time to union. Patients with risk factors for failure should be counseled on the outcomes and possible need for salvage fusion surgery.

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 grafts from the femur, including the medial femoral condyle and medial femoral trochlea, are increasingly being used. It is critical to understand the lower extremity complications from flap harvest. METHODS The authors searched available literature reporting on femoral flaps using PubMed, Embase, Cochrane Database, and Web of Science. After article selection, data were collected regarding demographics, procedure details, outcomes, and complications. The authors classified outcomes as good, fair, or poor based on pain, range-of-motion, sensory changes, subjective reporting, patient-reported outcomes, and other donor-site complications, including the need for additional procedures. RESULTS Two hundred twenty articles were identified. Forty-five met criteria for review, with data available for 283 patients. No patients had range-of-motion deficits beyond 1 year. Two percent of patients (six of 283) required additional donor-site procedures, with one report of a femur fracture after medial femoral condyle harvest. Only one study on 45 medial femoral trochlea patients presented patient-reported outcomes regarding the knee. Few objective data were presented. Twenty-eight articles presented adequate complication data for 252 patients to be rated as good, fair, or poor. Overall, 89 percent had good outcomes without donor-site complications. Of the 176 medial femoral condyle patients with outcomes reported, 92 percent had good outcomes; and 71 percent of the 48 medial femoral trochlea patients had good outcomes reported. CONCLUSIONS Overall, the reported donor-site morbidity from medial femoral condyle and medial femoral trochlea harvest is low. Chronic knee pain and sensory changes are most frequently reported, especially in medial femoral trochlea patients.

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
The medial femoral condyle vascularized graft has become a useful resource in reconstructive microsurgery due to the rate of bony union, and the low rate of complication. We report osteonecrosis of the medial femoral condyle in a 65-year-old woman after harvesting a corticocancellous medial femoral condyle graft to treat a tarsometatarsal nonunion. We were not able to define whether a vascular or mechanical disorder could be the ultimate cause. However, because of the severity of the complication, we suggest informing patients who will undergo a medial femoral condyle flap about this infrequent complication.

Abstract
Bone grafting in the upper extremity is an important consideration in patients with injuries or conditions resulting in missing bone stock. A variety of indications can necessitate bone grafting in the upper extremity, including fractures with acute bone loss, nonunions, malunions, bony lesions, and bone loss after osteomyelitis. Selecting the appropriate bone graft option for the specific consideration is important to ensure optimal patient outcomes. Considerations such as donor site morbidity and the amount and characteristics of bone graft needed all weigh in the decision making regarding which type of bone graft to use. This article reviews the options available for bone grafting in the upper extremity.

Abstract
Background: To report on the results of free medial femoral condyle (MFC) vascularized bone graft for scaphoid nonunions with 1 or more poor prognostic factors. Methods: We have used the free MFC vascularized bone graft for scaphoid nonunions that have 1 or more factors associated with a poor prognosis. These were, a delay in presentation of over 5 years, a proximal pole nonunion, the presence of avascular necrosis (AVN), or previous nonunion surgery. We used this technique on 20 patients over a 4.5-year period. Results: Our overall union rate was 88.5% (17 of 19 patients), with 1 patient failing to attend for follow-up. Our mean union time was 7 months (2-18). All patients had at least 1 poor prognostic factor and over half had 2 or more. Of those with AVN with or without other factors, the union rate was 85% (11 of 13). There were 2 donor site complications that required a further procedure and 2 patients with residual wrist pain that required a scapho-trapezio-trapezoid joint fusion and a radial styloidectomy, respectively. Both nonunions were offered further surgery, and 1 elected to undergo successful revision surgery. Conclusions: Overall, this technique showed good results, in a subgroup of patients that typically have poorer outcomes, with a low incidence of donor site morbidity. Our union rate compares favorably with other techniques for this difficult subset of patients with 1 or more poor prognostic factors, although results are clearly not as good as those of studies using the MFC graft for all scaphoid nonunions. We continue to reserve this technique for nonunions with 1 or more poor prognostic factors, and we believe that this technique should at least be considered in these patients.

Abstract
Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular.
