Large osteochondral lesions (OCLs) of the shoulder of the talus cannot always be treated by traditional osteochondral autograft techniques because of their size, articular geometry and loss of an articular buttress. We hypothesised that they could be treated by transplantation of a vascularised corticoperiosteal graft from the ipsilateral medial femoral condyle.

Between 2004 and 2011, we carried out a prospective study of a consecutive series of 14 patients (five women, nine men; mean age 34.8 years, 20 to 54) who were treated for an OCL with a vascularised bone graft. Clinical outcome was assessed using a visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. Radiological follow-up used plain radiographs and CT scans to assess graft incorporation and joint deterioration.

At a mean follow-up of 4.1 years (2 to 7), the mean VAS for pain had decreased from 5.8 (5 to 8) to 1.8 (0 to 4) (p = 0.001) and the mean AOFAS hindfoot score had increased from 65 (41 to 70) to 81 (54 to 92) (p = 0.003). Radiologically, the talar contour had been successfully reconstructed with stable incorporation of the vascularised corticoperiosteal graft in all patients. Joint degeneration was only seen in one ankle.

Treatment of a large OCL of the shoulder of the talus with a vascularised corticoperiosteal graft taken from the medial condyle of the femur was found to be a safe, reliable method of restoring the contour of the talus in the early to mid-term.

We report the use of a free vascularised iliac bone graft in the treatment of 21 patients (19 men and 2 women) with an avascular nonunion of the scaphoid in which conventional bone grafting had previously failed. The mean age of the patients was 32 years (23 to 46) and the dominant wrist was affected in 14. The mean interval from fracture to the vascularised bone grafting was 39 months (9 to 62). Pre-operative MRI showed no contrast enhancement in the proximal fragment in any patient. Fracture union was assessed radiologically or with CT scans if the radiological appearances were inconclusive. At a mean follow-up of 5.6 years (2 to 11) union was obtained in 16 patients. The remaining five patients with a persistent nonunion continued to experience pain, reduced grip strength and limited range of wrist movement. In the successfully treated patients the grip strength and range of movement did not recover to match the uninjured side. Prevention of progressive carpal collapse, the absence of donor site morbidity, good subjective results and pain relief, justifies this procedure in the treatment of recalcitrant nonunion of the scaphoid

There is a high risk of the development of avascular necrosis of the femoral head and nonunion after the treatment of displaced subcapital fractures of the femoral neck in patients aged < 50 years. We retrospectively analysed the results following fixation with two cannulated compression screws and a vascularised iliac bone graft. We treated 18 women and 16 men with a mean age of 38.5 years (20 to 50) whose treatment included the use of an iliac bone graft based on the ascending branch of lateral femoral circumflex artery. There were 20 Garden grade III and 14 grade IV fractures. Clinical and radiological outcomes were evaluated. The mean follow-up was 5.4 years (2 to 10). In 30 hips (88%) union was achieved at a mean of 4.4 months (4 to 6). Nonunion occurred in four hips (12%) and these patients had a mean age of 46.5 years (42 to 50) and underwent revision to a hip replacement six months after operation. The time to union was dependent on age with younger patients achieving earlier union (p < 0.001). According to the Harris hip score which was available for 27 of the 30 hips with satisfactory union, excellent results were obtained in 15 (score ≥ 90 points), fair in ten (score 80 to 90 points), and poor in two hips (≤ 80 points). One patient aged 48 years developed avascular necrosis of femoral head six years after operation and underwent total hip replacement.

The management of displaced subcapital fractures of the femoral neck, in patients aged <  50 years, with two cannulated compression screws and an iliac bone graft based on the ascending branch of lateral femoral circumflex artery, gives satisfactory results with a low rate of complication including avascular necrosis and nonunion.

Aims

This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus.

Surgical treatment of infected bones with vascularised bone grafts is well established as an efficient strategy since several years. Nevertheless orthopaedic and trauma surgeons seem to apply vascularised bone grafts as the last treatment option only. Two strategies exist for treatment of chronically infected bones with vascularised bone grafts. First: Complete resection of the infected, often non-united part of the bones and reconstruction with large vascularised bone grafts, mostly fibular grafts. Second: Augmentation of the kept and intact parts of the bones with vascularised bone grafts. Two small series of patients are presented to illustrate both techniques and to show the results and outcome. Resection of big parts of the tibia and reconstruction with mostly ipsilateral fibular grafts – single barrel in children and double barrel in adults – led to uneventful healing in all cases. Augmentation of radius, femur and calcaneus with vascularised grafts from the iliac crest or the scapula was followed by primary healing, too. All patients were disburdened from infection up to now and regained full extremity function. The presented vascularized bone grafts did not only salvage the extremities but also could maintain their functionality. The procedure is demanding, but reliable and safe at a low rate of complications. Thus vascularised bone grafts should not only be used as ultimative salvage procedures, but as early as possible whenever standard treatments for osteomyelitis fail

Aim: To determine the viability and long term survival of a unique Patellar reconstruction technique, using the posterior femoral condyle, at primary TKR, in patients with previous patellectomy. Methods: The posterior lateral femoral condyle cut during total knee replacement was used as a non- vascularised bone graft to reconstruct the patella. A medial para- patellar incision was used to create a Patellar pouch. The patient was examined clinically at operation, 6 weeks, 12 months, 2 years and 4 years from operation. Clinical examination and radiographic evidence of patellar position and survival were used. Results: The patient has a stable, well positioned patella, with no pain from the graft and no clinical evidence of Mal- tracking. Radiographs show excellent survival of the graft and good position at 4 years. Conclusion: Patellar reconstruction using non- vascularised bone graft via a medial patellar pouch is a viable alternative surgical option to aid stability in those patients undergoing primary TKR with previous patellectomy

Introduction. The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration. Materials & Methods. Sixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents

Background Scaphoid non-union remains a difficult problem to treat effectively. Screw fixation and standard bone grafting techniques are good options with union reported in approximately 90% of cases. Studies of the vascular supply to the distal radius have revealed a consistent vascular bone graft source from the dorsal radius. This allows for a pedicled vascularised bone graft to be fashioned, further enhancing the local blood supply to the fracture site. Methods 14 male patients with a mean age of 30 years (21 to 51 years) and a mean duration of injury of 57 months (15 – 348 months) underwent vascularised bone grafting of established non–union of the scaphoid. The graft was vascularised with a pedicle based on the 1, 2 intercompartmental supraretinacular branch of the radial artery. In addition the long standing deformity resulting from the non-union was corrected by a tri-cortical iliac crest bone graft. (The results were assessed with regard to evidence of union at the fracture site and resolution of pain with return of function). Some of the cases had previous operations with conventional bone graft and failed. Results Fracture healing was demonstrated radiologically in 9 of 14 cases (64%). 12 of 14 cases (86 %) showed resolution of pain and improvement in function. Conclusion This technique shows promising results for treating established non-union of the scaphoid, even after long intervals between initial injury and the grafting procedure

Introduction: We report on our experience of using a vascularised bone graft harvested from the volar face of the radius in the treatment of Kienböck’s disease, with an average follow up of 79 months and a minimum of 5 years. Materials: We treated 22 patients with Kienböck’s disease. There were 8 women and 14 men whose average age was 31.4 years old (range 18–63 years). Pain was always present and incapacitating in 19 cases. All patients underwent pre-operative tomodensitometry and an MRI, based on LICHTMAN’s classification there were 8 stage II, 10 stage IIIA and 4 stage IIIB. Methods: The volar carpal artery of the carpus originates from the radial artery and vascularises medial part of the radial epiphysis. Using the same anterior surgical approach it was possible to harvest the pedicled bone graft from this artery and to place it into the lunate for revascularisation. Shortening of the radius was carried out in all cases, as was immobilisation until union of the radius. Results: Our average follow up is 79 months (range 60–138 months). Pain disappeared completely in 20 cases, and was moderate and tolerable in 2 cases. The average active range of motion was higher than 71°. The average period for return to work was 3.5 months. Post-operative MRI at an average of more than 8 months showed 16 complete revascularisations of the lunate, 5 stabilizations of lesions and one failure which necessitated secondary palliative treatment. There were 4 delayed unions of the radius and one Südeck’s dystrophy. There was a clear correlation between the stage of Kienböck’s disease and the final outcome of surgery. Discussion: The use of a vascularised bone graft harvested from the anterior face of the radius for the revascularisation of the lunate associated with shortening of the radius has given encouraging results. A longer-term study is necessary

To determine union rate in complicated nonunions of the scaphoid treated with a vascularised bone graft. Vascularised bone grafting for scaphoid nonunions (1–2 ICSRA, Zaidemberg technique) has shown initial enthusiasm. Its usefulness has been challenged in cases where the proximal pole of the scaphoid is avascular. Complicated nonunions where the proximal pole is highly likely to be avascular occur in revision surgery and proximal pole nonunions. Fourteen patients were retrospectively followed up. Eight had nonunion following previous scaphoid surgery (two previous ORIF, two previous nonvascular grafting, and four with two previous surgeries). Six patients had no previous surgery for a proximal pole nonunion of 12.5 months’ duration. All patients were male with an average age of twenty-four. Delay from fracture to vascularised bone grafting was twenty months. Graft harvesting was done according to the Zaidemberg technique by two orthopaedic surgeons. CT-scan was used to confirm union in all patients except two who were lost of the follow-up. Twelve patients were followed up by an independent surgeon at a postoperative minimal period of four months. Functional status was assessed with the DASH questionnaire and follow x-rays were performed to determine the presence of degenerative changes. Union was confirmed by CT-scan in eleven of twelve followed patients (92%) at an average time of six months following vascularised graft. Radio-scaphoid osteoarthritis was seen in the one patient that didn’t achieve union. This series suggests that the Zaidemberg graft is useful and may be proposed in situations of revision surgery and proximal pole non-unions. We achieved a high union rate in these complicated nonunions even though there was high likelihood that the proximal pole was avascular. This study stresses the importance of protective immobilization until documented union by CT-scan in this difficult subset of patients

We evaluated the outcome of treatment of nonunion of an intracapsular fracture of the femoral neck in young patients using two cannulated screws and a vascularised bone graft. A total of 32 patients (15 women and 17 men, with a mean age of 36.5 years; 20 to 50) with failed internal fixation of an intracapsular fracture were included in the study. Following removal of the primary fixation, two cannulated compression screws were inserted with a vascularised iliac crest bone graft based on the ascending branch of the lateral femoral circumflex artery. At a mean follow-up of 6.8 years (4 to 10), union was achieved in 27 hips (84%). A total of five patients with a mean age of 40.5 years (35 to 50) had a persistent nonunion and underwent total hip arthroplasty as also did two patients whose fracture united but who developed osteonecrosis of the femoral head two years post-operatively. Statistical analysis showed that younger patients achieved earlier and more reliable union (p < 0.001). The functional outcome, as assessed by the Harris Hip score, was better in patients aged < 45 years compared with those aged > 45 years (p < 0.001). . These findings suggest that further fixation using two cannulated compression screws and a vascularised iliac crest bone graft is an effective salvage treatment in patients aged <  45 years, in whom osteosynthesis of a displaced intracapsular fractures of the femoral neck has failed.

Purpose. Scaphoid non-unions can result in debilitating wrist problems. This study compared treatment of scaphoid non-unions using either a non vascularised (NVBG) or a vascularised bone graft (VBG). Method. Twenty one cases of scaphoid non-unions were treated by two surgeons between 2005 and 2008 using either a NVBG from the iliac crest or a VBG from the radius based on a 1,2 intercompartmental supraretinacular artery pedicle. Results. Of the 21 cases only 19 were available followed up at a minimum of 3 months with 12 cases available for clinical follow-up 2–5 years postoperatively. Union was achieved in 9 of 11 cases in the VBG group and in 6 of the 8 cases in the NVBG group with no statistically significant difference in average time to union. Wrist range of motion was compared at the time of consolidation and at the follow-up showing no significant difference between the two groups. 11 patients completed the Dash-score and the Mayo-wrist-score with similar results in both groups. Conclusion. This study could not demonstrate any significant differences in clinical and functional outcome at the time of confirmed fracture union or at a late follow-up

We describe a new method of reconstruction after resection of tumours of the proximal tibia by grafting and arthrodesis of the knee. Two separate vascularised bone grafts from the ipsilateral limb were used, one a gastrocnemius-pedicled femoral graft and the other a pedicled fibular graft. An anatomical study of the gastrocnemius-pedicled femoral graft was made. The method was shown to be practical and reproducible. One patient with osteosarcoma has a successful result with no recurrence at two-and-a-half years

Ten adults were studied two to seven years after resection of a fibula for use as a free vascularised bone graft. Six had no symptoms in the donor leg, four had some aching, weakness or paraesthesia and three had definite weakness of the long toe flexors and extensors. All knees and ankles were clinically and radiologically stable, but the distal fibular remnant was osteoporotic in nine patients. Gait analysis of the donor leg and the contralateral normal leg showed definite differences, which could be attributed to weakness of the deep muscles caused by loss of their normal origin and to the change in load transmission through the fibula

Introduction. Scaphoid nonunions remain controversial with regard to optimal management. The objective of this article is to compare our clinical experience in the treatment of patients with scaphoid nonunion using distal radius non vascularised bone graft with that of iliac crest bone graft. Material & Methods. We conducted a prospective randomized study comparing the clinical, functional and radiographic results of 42 patients treated for scaphoid nonunion using a non-vascularised bone graft from the dorsal and distal aspect of the radius (group I), relative to 46 patients treated by means of a conventional non-vascularised bone graft from the iliac crest (group II). All nonunions were stabilized with single Herbert screw. Results. Bone fusion was achieved in 87.1% of group I and 86.5% of group II patients. Functional results were good to excellent in 76.0% of the patients in group I and 72.5% in group II. The average grip power, as well as wrist flexion and extension were similar in both groups. However, the donor site morbidity was much higher in group II (4 cases of hematoma, 6 cases of chronic pain and 1 anterior superior iliac spine avulsion) fracture. No complication was seen in group I. Conclusion. We conclude that nonvascularized distal radius bone grafting yields similar union rate as well as functional outcome as compared to iliac crest bone graft with no donor site morbidity

Between June 2005 and March 2008, 14 patients with a Campanacci grade-3 giant-cell tumour of the distal radius were treated by en bloc resection and reconstruction by ulnar translocation with arthrodesis of the wrist. The mean length of radius resected was 7.9 cm (5.5 to 15). All the patients were followed to bony union and 12 were available at a mean follow-up of 26 months (10 to 49). The mean time to union was four months (3 to 7) at the ulnocarpal junction and five months (3 to 8) at the ulnoradial junction. All except one patient had an excellent range of pronation and supination. The remaining patient developed a radio-ulnar synostosis. The mean Musculoskeletal Tumor Society score was 26 (87%, range 20 to 28). Three patients had a soft-tissue recurrence, but with no bony involvement. They underwent a further excision and are currently well and free from disease. Ulnar translocation provides a local vascularised bone graft to reconstruct the defect left after excision of the distal radius for giant cell tumour. It avoids the need for a microvascular procedure while retaining rotation of the forearm and good function of the hand

The Authors report their experience in the treatment of scaphoid non-union recurring to the vascularised bone graft technique as described by Zeidemberg. The patients have been treated between the 1999 and 2004. The authors report 22 cases (21 males and 1 female) with an average age of 31 years (from 17 to 42). 10 cases the involved wrist was the right one and in the other 12 cases was the left one. 18 patients presented an avascular necrosis of the proximal fragment of the scaphoid, recognised by the MNR. Two patients have been previously treated by the traditional bone graft technique as described by Matti-Russe, using a cannulated screw for the stabilization of the graft. 16 patients have been controlled at the follow-up (mean 23 months, from 3 to 65). The authors, looking at the good results obtained at the follow-up, feel that this technique might be a very useful one in the treatment of the established scaphoid non-union, mainly in presence of an avascular necrosis of the proximal third of the scaphoid. This technique might also be useful in the treatment of the failure of the classic bone graft technique

The ipsilateral and contralateral fibulae have been used as a vascularised bone graft for loss of tibial bone usually by methods which have involved specialised microvascular techniques to preserve or re-establish the blood supply. We have developed a method of tibialisation of the fibula using the Ilizarov fixator system, ipsilateral vascularised fibular transport (IVFT), and have used it in five patients with massive loss of tibial bone after treatment of an open fracture, infected nonunion or chronic osteomyelitis. All had successful transport, proximal and distal union, and hypertrophy of the graft without fracture. One developed a squamous-cell carcinoma which ultimately required amputation of the limb. The advantage of IVFT is that the fibular segment retains its vascularity without the need for microvascular dissection or anastomoses. Superiosteal formation of new bone occurs if the tibial periosteal bed is retained. Other procedures such as corticotomy and lengthening can be carried out concurrently

Following a laboratory rat study where iliac crest was removed, the femoral vessels were placed as a pedicle through the centre of the graft which was wrapped in silastic sheeting and transplanted to the subcutaneous abdominal wall, which showed in all cases bone revascularisation and viability within three weeks. A human study followed in two patients with chronic complex scaphoid non unions where iliac crest was placed in the anterior interosseous pedicle in the proximal forearm. The pedicle was ligated proximally. Four months later, the graft was dissected on its pedicle distally to the scaphoid. In both cases, the scaphoid united and in both cases the bone was viable at biopsy. Rather than this tedious two stage procedure, Russe and Fisk grafts are routinely pedicled with the superficial radial vessels flowing retrograde at scaphoid bone grafting. At the same time of our rat study, Zaidemberg published his dorso-radial radius vascularised pedicled bone graft on the “irrigating artery”. The details were scant as they were at the oral presentation three years later. The irrigating artery was subsequently beautifully demonstrated in Zancolli’s Atlas of Hand Surgery and this and other dorsal pedicled bone grafts of the radius have been well described by Bishop and colleagues at the Mayo Clinic. The technique of 1-2 SRA (Zaidemberg) pedicled bone grafting is described in detail together with the indications for prefabrication and vascularised pedicled bone grafting and the necessary pre operative imaging information to plan and select the correct procedure

We describe the use of a vascularised periosteal patch onlay graft based on the 1,2 intercompartmental supraretinacular artery in the management of 11 patients (ten men, one woman) with chronic nonunion involving the proximal third of the scaphoid. The mean age of the patients was 31 years (21 to 45) with the dominant hand affected in eight. Six of the patients were smokers and three had undergone previous surgery to the scaphoid. All of the proximal fragments were avascular. The presence of union was assessed using longitudinal axis CT. Only three patients progressed to union of the scaphoid and four required a salvage operation for a symptomatic nonunion. The remaining four patients with a persistent nonunion are asymptomatic with low pain scores, good grip strength and a functional range of wrist movement. Although this technique has potential technical advantages over vascularised pedicled bone grafting, the rate of union has been disappointing and we do not recommend it as a method of treatment
