Resection-reconstruction arthroplasty for giant cell tumor of distal radius

Background:

Giant cell tumor (GCT) of the distal radius poses problems for reconstruction after resection. Several reconstructive procedures like vascularized and non-vascularized fibular graft, osteo-articular allograft, ceramic prosthesis and megaprosthesis are in use for substitution of the defect in the distal radius following resection. Most authors advocate wrist arthrodesis following resection of distal radius and non vascularized fibular graft. Here we have analyzed the results of aggressive benign GCTs of the distal radius treated by resection and reconstruction arthroplasty using autogenous non-vascularized fibular graft.

Materials and Methods:

Twenty-four cases of giant cell tumor of the distal radius (mean age 32 years, mean follow-up 6.6 years) treated by en-bloc resection and reconstruction arthroplasty using autogenous non-vascularized ipsilateral fibular graft with a minimum followup of two years have been included in this retrospective study. Nineteen cases were of Campanacci grade III and five were of Grade II recurrence. The mean resected length of the radius was 9.5 (8-12) cm. Routine radiographs and clinical assessments regarding pain, instability, recurrence, hand grip strength and functional status were done at regular intervals and functional results were assessed using (musculoskeletal tumor society) MSTS-87 scoring.

Results:

Early radiological union at host-graft junction was achieved at mean 12.5 weeks, (range 12-14 weeks) and solid incorporation with callus formation was observed in mean 29 weeks (range 28-32 weeks) in all the cases. Satisfactory range of motion (mean 63%, range 52-78%) of the wrist was achieved in 18 cases. Grip strength compared to the contralateral hand was found to be 67% (range 58-74%). Functional results were excellent in six cases (25%), good in 14 cases (58.3%) and four (16.7%) cases had fair results. Soft tissue recurrence was seen in one patient. The most commonly encountered complication was fibulo-carpal subluxation (10 cases, 41.7%).

Conclusion:

Resection of the distal radius and reconstruction arthroplasty with non-vascularized proximal fibular graft is useful in preserving the functional movement and stability of the wrist as well as achieving satisfactory range of movement and grip strength.     

Functional outcome of en bloc resection and osteoarticular allograft reconstruction with locking compression plate for giant cell tumor of the distal radius

Background

Giant cell tumors of the distal radius at Campanacci grade III are particularly challenging to treat. We have treated 15 cases of giant cell tumor of the distal radius by en bloc excision and osteoarticular allograft reconstruction with locking compression plate (LCP). The purpose of this study was to assess the intermediate outcomes of all patients treated with this surgery.

Methods

From July 2002 to January 2009, we followed up 15 patients with giant cell tumors of the distal radius who were treated with en bloc excision and osteoarticular allograft reconstruction with LCPs that were long enough to approach the distal end of the allograft. All of the cases were evaluated based on clinical and radiologic examinations, the passive range of motion of the wrist joint, complications, Mayo wrist score, and short form (SF)-36.

Results

The clinical follow-up time after reconstruction averaged 5.2 years. The mean resected length of the radius was 8.1 cm. One patient had tumor recurrence in the soft tissues after 3 years (recurrence rate 6.67 %). No patient had allograft bone fracture, nonunion, or metastases. Subchondral bone alterations and joint narrowing were present in all cases, with 1 patient suffering from the pain, but the pain could be endured without the need for analgesics. The average range of motion of the wrist was 46.7° of dorsiflexion, 33.3° of volar flexion, 61.3° of supination, and 72.3° of pronation. The mean Mayo wrist score was 70 and the mean modified SF-36 score was 71.

Conclusions

En bloc excision and osteoarticular allograft reconstruction with an appropriate LCP for a Campanacci grade III giant cell tumor of the distal radius result in a reasonable functional outcome at intermediate follow-up evaluation. This method can excise the tumor integrally with a low rate of recurrence, good function, and a satisfactory range of motion.     

Operative technique of distal radius resection and wrist fusion with iliac crest bone graft

Malignant lesions of distal radius and appropriately selected cases of benign aggressive lesions (giant cell tumor) of distal radius require resection for limb salvage. Post resection, reconstruction of that defect can be accomplished by either arthrodesis or arthroplasty both having their own pros and cons. In cases undergoing arthrodesis as modality of reconstruction, small defects (≤6 cm) can be reconstructed using autologous iliac crest bone graft which results in good cosmetic appearance and functional outcome. We have described in detail, the preoperative planning, surgical steps and rehabilitation of wrist fusion with iliac crest bone grafting post distal radius resection.

Hernia mesh prevent dislocation after wide excision and reconstruction of giant cell tumor distal radius

Giant cell tumor(GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome.     

En bloc excision and autogenous fibular reconstruction for aggressive giant cell tumor of distal radius: a report of 12 cases and review of literature

Introduction  

Giant cell tumor (GCT) of distal radius follows a comparatively aggressive behaviour. Wide excision is the management of choice, but this creates a defect at the distal end of radius. The preffered modalities for reconstruction of such a defect include vascularized/non-vascularized bone graft, osteoarticular allografts and custom-made prosthesis. We here present our experience with wide resection and non-vascularised autogenous fibula grafting for GCT of distal radius.     

Distal radioulnar joint prosthesis for the treatment of giant cell tumor of the distal ulna: a case report and literature review

Giant cell tumor (GCT) of the distal end of the ulna is an uncommon site for primary bone tumors. When it occurs, en-bloc resection of the distal part of the ulna with or without reconstruction stabilization of the ulnar stump is the recommended treatment. We present a case of a 56-year-old man with a GCT of the distal ulna treated successfully with an en-bloc resection of the distal ulna with reconstruction using radioulnar joint prosthesis. Although the experience with this type of treatment is limited, implantation of a metallic prosthesis to replace the distal part of the ulna can also be considered as a salvage procedure for the treatment of this difficult pathology.     

Giant cell tumor of distal ulna treated using en-bloc resection combined with extensor carpi ulnaris and flexor carpi ulnaris tendon stabilization: A case report

IntroductionGiant Cell Tumor (GCT) is a form of bone tumor which is rare, benign, and locally invasive. To date, there have not been many case reports regarding cases of GCTs on the distal ulna which made the optimum strategy in management remain controversial. In some reported cases, the patient was treated with wide excision followed by reconstructive procedure resulting in ulnar translation of the carpal bones and dynamic convergence of the ulna towards the radius.Presentation of caseWe documented a case of 29-year-old male with distal ulna GCT, treated with en-bloc resection combined with extensor carpi ulnaris and flexor carpi ulnaris tendon stabilization. The key objectives of GCT treatments are to avoid local recurrence with sufficient resection and to maintain the function of the limbs. Specific treatment options have been suggested for en-bloc resection with or without the need for ulnar reconstruction or stabilization, even prothesis. In this case, we excised the distal portion of the ulna with some soft tissue procedure for added stability.Clinical discussionThree weeks after the surgery, the patient was able to perform wrist flexion and extension, fingers abduction, adduction, and opposition with slight limitation. The DASH and PRWE score had improved gradually within 3 weeks and 6 months after the surgery.ConclusionIn the subsequent evaluation after six months of the surgery, the patient achieved full restoration of forearm function without any limitation.     

Is Intralesional Treatment of Giant Cell Tumor of the Distal Radius Comparable to Resection With Respect to Local Control and Functional Outcome?

Background

A giant cell tumor is a benign locally aggressive tumor commonly seen in the distal radius with reported recurrence rates higher than tumors at other sites. The dilemma for the treating surgeon is deciding whether intralesional treatment is adequate compared with resection of the primary tumor for oncologic and functional outcomes. More information would be helpful to guide shared decision-making.

Questions/purposes

We asked: (1) How will validated functional scores, ROM, and strength differ between resection versus intralesional excision for a giant cell tumor of the distal radius? (2) How will recurrence rate and reoperation differ between these types of treatments? (3) What are the complications resulting in reoperation after intralesional excision and resection procedures? (4) Is there a difference in functional outcome in treating a primary versus recurrent giant cell tumor with a resection arthrodesis?

Methods

Between 1985 and 2008, 39 patients (39 wrists) were treated for primary giant cell tumor of the distal radius at two academic centers. Twenty patients underwent primary intralesional excision, typically in cases where bony architecture and cortical thickness were preserved, 15 underwent resection with radiocarpal arthrodesis, and four had resection with osteoarticular allograft. Resection regardless of reconstruction type was favored in cases with marked cortical expansion. A specific evaluation for purposes of the study with radiographs, ROM, grip strength, and pain and functional scores was performed at a minimum of 1 year for 21 patients (54%) and an additional 11 patients (28%) were available only by phone. We also assessed reoperations for recurrence and other complications via chart review.

Results

With the numbers available, there were no differences in pain or functional scores or grip strength between groups; however, there was greater supination in the intralesional excision group (p = 0.037). Tumors recurred in six of 17 wrists after intralesional excision and none of the 15 after en bloc resection (p = 0.030). There was no relationship between tumor grade and recurrence. There were 12 reoperations in eight of 17 patients in the intralesional excision group but only one of 11 patients (p = 0.049) who underwent resection arthrodesis with distal radius allograft had a reoperation. There were no differences in functional scores whether resection arthrodesis was performed as the primary procedure or to treat recurrence after intralesional excision.

Conclusions

Resection for giant cell tumor of the distal radius with distal radius allograft arthrodesis showed a lower recurrence rate, lower reoperation rate, and no apparent differences in functional outcome compared with joint salvage with intralesional excision. Because an arthrodesis for recurrence after intralesional procedures seems to function well, we believe that intralesional excision is reasonable to consider for initial treatment, but the patient should be informed about the relative benefits and risks of both options during the shared decision-making process. Because arthrodesis after recurrence functions similar to the initial resection and arthrodesis, an initial treatment with curettage remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss.

Level of Evidence

Level III, therapeutic study.     

Giant cell tumor of the thumb proximal phalanx: resection-iliac graft and double arthrodesis

Giant cell tumours (GCT) of bone are frequent, with variable behaviour, high risk of recurrence and an often benign histological appearance. Their location in the hand is uncommon, and there are few publications on the subject. Surgical treatment as described in the literature is very variable. We report a case of recurrent grade II GCT, arising in the proximal phalanx of the thumb, aggressive and causing a pathological fracture. After a surgical biopsy, we performed an "en bloc" resection of the first phalanx, with an iliac crest graft reconstruction and a double arthrodesis of the metacarpophalangeal and interphalangeal joint. No recurrence or lung metastasis was seen at 18 months follow-up.     

Granular Cell Tumor of the Abdominal Wall: Case Report and Review of the Literature

Granular cell tumors (GCT’s) are uncommon soft tissue neoplasms most likely of neural or neuroectodermal origin. They can be found in virtually any body site, but they are rarely located in the abdominal wall. We report the case of a patient with a history of breast cancer presenting with a slow-growing, firm and painless nodule in the abdominal wall. After ruling out metastatic origin of the mass by CT scan and MRI, an incisional biopsy was performed. Anatomopathologic findings were congruent with a benign granular cell tumor of the abdominal wall. En-bloc surgical resection with reconstruction of the abdominal wall defect using a prosthetic mesh was performed. Preoperative histopathologic diagnosis of an abdominal wall tumor is important. ‘Broad surgical excision to obtain negative margins should be the therapeutic goal in all cases of GCT as positive margins are highly correlated with recurrence of the lesion.     

Outcomes of short segment distal radius resections and wrist fusion with iliac crest bone grafting for giant cell tumor

BackgroundDistal radius is third most common site for occurrence of Giant cell tumor (GCT) of bone. Most of Campanacci grade II & III cases require resection. Reconstructions of these defect are challenging. Though fibular arthroplasty provides mobility at wrist but is fraught with complications of donor site morbidity and instability with wrist pain. Wrist arthrodesis with ulna translocation provides stable reconstruction but is cosmetically less appealing. We present a series of 12 cases of GCT of distal radius treated with short segment (6 cm or less) resections and wrist fusion with iliac crest grafting. We evaluated donor site morbidity, functional and oncological outcomes.ObjectivesTo assess time to union, donor site morbidity, functional and oncological outcomes after wrist fusion with iliac crest bone grafting for distal radius resection (≤6 cm).MethodsRetrospective analysis was performed from a prospectively maintained database between January 2011 and December 2017, 12 patients (7 male and 5 female; 9 primary and 3 recurrent; all Campanacci grade III) were included. Mean age was 29 years (15–41 years) with mean resection length of 5.1 cm (4.5–6 cm). The dominant hand was involved in 6 patients. Time to union, donor site morbidity, functional and oncologiacal outcomes were evaluated. Functional outcomes were evaluated using Musculo-Skeletal Tumor Society (MSTS) score and Patient Rated Wrist Evaluation (PRWE) score. Grip strength and arc of forearm rotation were also evaluated.ResultsAll patients were available for analysis. No symptomatic donor site morbidity was observed. One patient had prominent implant following a fall and delayed union. Mean time to union for 22 osteotomy sites in rest of 11 patients (both proximal and distal) was 6 months (4–11 months). At median follow up of 45 months (18–78 months) 2 patients had soft tissue recurrence, 1 had a stable pulmonary metastasis. Local Recurrence rate was 17%. All patients returned to their pre surgery activity. Mean MSTS score was 25 (19–29) and PRWE score was 12 (6–28). Grip strength and Prono - supination measurements were available in 10 patients. Grip strength was 69% of non operated limb. Mean supination was 53° (0° to 80°) and mean protonation was 73° (40° to 80°). Mean arc of rotation was 126° (80° to 160°).ConclusionReconstruction of distal radius bone defects with Iliac crest bone grafting and wrist arthrodesis retains prono-supination while maintaining wrist girth (cosmesis). The oncologic and functional outcomes make it an acceptable modality in selected cases of distal radius tumours with short resection length (≤6 cm).     

Functional outcome of en bloc excision and osteoarticular allograft replacement with the Sauve-Kapandji procedure for Campanacci grade 3 giant-cell tumor of the distal radius

PURPOSE: Multiple options have been reported for reconstruction of Campanacci grade 3 giant-cell tumor of the distal radius after resection. In 1990, the senior author described an allograft reconstruction combined with a Sauve-Kapandji procedure after distal radius resection and reported preliminary results in 3 patients. The purpose of this study was to assess with validated patient outcome surveys the intermediate to long-term outcomes of all patients treated with this surgery and to analyze their functional results and document tumor control. METHODS: All cases of distal radius osteoarticular allograft combined with the Sauve-Kapandji reconstruction for Campanacci grade 3 giant-cell tumors performed from 1986 to 2000 by a single surgeon were evaluated by clinical and radiologic examinations; the Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form-36; and Mayo Wrist scores. RESULTS: Nine consecutive patients (7 women, 2 men) with an average age at follow-up evaluation of 42 years and with a Campanacci grade 3 giant-cell tumor of the distal radius formed the study population. Clinical follow-up time after reconstruction averaged 7 years. Examination showed an average of 51 degrees of extension and 19 degrees of flexion of the wrist and 63 degrees of supination and 79 degrees of pronation of the forearm. Grip strength measured in 5 patients averaged 23 kg. The Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form-36; and the Mayo Wrist scores averaged 15, 72, and 73, respectively. These scores indicate modest functional impact. No patient had tumor recurrence, metastases, nonunion, or proximal ulna instability. CONCLUSIONS: En bloc resection of a Campanacci grade 3 giant-cell tumor of the distal radius followed by reconstruction with an osteoarticular allograft and a Sauve-Kapandji procedure with autogenous bone graft results in a reasonable functional outcome at intermediate to long-term follow-up evaluation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.     

Neue Therapieansätze beim Riesenzelltumor

Background

Giant cell bone tumors (GCT) are benign but partially locally aggressive osteolytic tumors which typically occur around the knee joint in the epiphysis and metaphysis of long bones after maturation of the skeleton is completed. Due to the locally aggressive growth behavior with destruction of the bone structure, the rare possibility of pulmonary metastases in recurrent cases and a very rare possibility of malignancy, GCTs were previously also described as semimalignant bone tumors.

Therapy

The established therapy of these tumors at the typical locations consists of intralesional curettage, extension of resection margins using a high speed trephine and defect reconstruction with bone cement. The local recurrence rate is high (10–40?%) and lowest after using thermal extension of resection margins with a high speed trephine and defect reconstruction with bone cement. For uncommon localizations, such as the spinal column and the sacrum as well as in cases of recurrence, surgical treatment is more complicated.

Histology

Histologically, GCTs consist of osteoclastic giant and oval-shaped stromal cells which show a high expression of receptor activator of nuclear factor-κB ligand (RANKL) and decisively contribute to the osteolytic activity of the tumor. Novel pharmaceutical therapy approaches with human monoclonal RANKL antibodies interfere in this osteodestructive process in an inhibitory manner and can represent alternative treatment options just as the osteosupportive therapy with bisphosphonates.

Conclusion

After unsatisfactory attempts at surgical treatment of GCT patients, the new treatment option with denosumab is a promising alternative due to its effect as a monoclonal RANKL inhibitor. Nach unbefriedigenden chirurgischen Therapieversuchen bei RZT-Patienten ist Denosumab durch seine Wirkung als monoklonaler RANKL-Inhibitor als neue Behandlungsoption eine vielversprechende Alternative.     

Reconstruction of distal radius by fibula following excision of grade III giant cell tumour: Follow-up of 18 cases

The purpose of this study was to evaluate the long-term results of vascularised fibular graft for reconstruction of the wrist after excision of grade III giant cell tumour in the distal radius. From January 1998 to September 2003, 18 patients with wrist defects due to distal radius grade III giant cell tumour resection were treated with vascularised fibular graft and were followed-up. The limb function was restored to an average 80% of normal function and bone union was achieved within six months in 18 patients with vascularised fibular graft. MSTS score averaged 25.6 and ranged between 21 and 29; Mayo wrist score averaged 56 with a range from 40 to 65. It is appropriate to use the head of the fibula as a substitute for the distal radius. The healing of vascularised fibular graft is very quick and without bone resorption. Thus, in the procedure for reconstruction and limb salvage after bone tumour resection of distal radius, the free vascularised fibular graft with fibular head is an ideal substitute.     

Ilizarov reconstruction of the distal radius after resection of a giant-cell tumor: a case report

We present a case of Ilizarov reconstruction after en bloc resection of the distal radius. An 8-cm resection was required to remove a giant-cell tumor. Reconstruction was based on the ascension technique using an Ilizarov external fixator after corticotomy of the proximal fragment of the radius. Satisfactory reconstruction with formation of a neoarticulation between the radius and the carpus was achieved. Satisfactory wrist function was achieved and the patient was recurrence free at five years. The arguments leading to this therapeutic option are discussed.     

Fibular Strut Arthrodesis for Salvage of Campanacci Grade III Giant Cell Tumor of the Hallucal Proximal Phalanx: A Case Report

Involvement of toe phalanges by giant cell tumor (GCT) is extremely rare; tumors in these locations tend to be aggressive. Whereas aggressive GCTs of the distal phalanx may be managed successfully by en-bloc resection without reconstruction or amputation, management of these lesions, when they involve the proximal phalanx, can be challenging. We present a Campannaci grade III GCT of the hallucal proximal phalanx in a 14-year old girl that had breached into the dorsal soft tissues and the metatarso-phalangeal joint. Wide local resection of the proximal phalanx along with reconstruction arthrodesis with an autologous, non-vascularized fibular strut graft was performed. There was no recurrence at 3 years of follow-up. The patient had an excellent functional outcome. To the best of our knowledge, this is the first case reporting the outcomes of fibular strut arthrodesis for salvage of GCT of the hallucal proximal phalanx.
