Chondrosarcoma of the hand is a rare disease, but is one of the more common malignancies of the hand. Biopsies and imaging are a fundamental step in determining correct diagnosis, grading and selection for best treatment. We describe the case of a 77-year-old male complaining of a painless swelling in the proximal phalanx of the third ray of left hand. A biopsy was performed and the histology revealed a G2 chondrosarcoma. The patient underwent III ray amputation with metacarpal bone disarticulation and sacrifice of the radial digit nerve of the fourth ray. Definitive histology revealed grade 3 CS. Eighteen months after surgery, the patient is apparently disease-free with a good functional and aesthetic outcome although with persistent paresthesia of the fourth ray. Although there is no agreement in the literature for the treatment of low-grade chondrosarcomas, wide resection or amputation can be considered the mainstay treatment for high-grade tumors.

Giant-cell tumor (GCT) is often more aggressive when located in the distal radius, and wide resection is then the gold-standard. No single reconstruction protocol is recommended, and the technique depends upon the surgeon's preferences. The aim of the present review was to determine the recurrence rate of GTC of the distal radius after intralesional treatment, to assess the results, advantages and complications of the various surgical techniques, and to draw up a decision-tree for surgical indications. The review of literature was performed in the main healthcare databases, searching for studies that reported results of wide resection and reconstruction of distal radius GCT. Local recurrence rates, metastasis rates, reconstruction techniques and respective results and complications were evaluated and analyzed. Sixteen studies were selected, for a total population of 226 patients; 6.0% and 0.9% experienced local recurrence and lung metastasis, respectively. Arthroplasty with non-vascularized or vascularized ipsilateral fibula were the most common techniques and were associated with the highest satisfaction rates: 86.4% and 88.0%, respectively. Arthroplasty with allograft presented a MusculoSkeletal Tumor Society (MSTS) score of 79.2% and arthroplasty with custom-made prosthesis presented an MSTS score of 81.8%. Arthrodesis was performed in 46 cases, with an MSTS score of 82.7%. Arthroplasty techniques are the most common in literature; they are used in patients who wish to conserve joint motion. Reconstruction with non-vascularized fibula seems to provide the best results, with lower morbidity. Arthrodesis is usually reserved for heavy manual workers or in case of arthroplasty failure., (Copyright © 2022 SFCM. Published by Elsevier Masson SAS. All rights reserved.)

Reconstruction is very important to ensure good function and quality of life after bone tumor resection. For metacarpals and phalanges, amputation and toe transfer are the gold-standard indications; nevertheless, allograft reconstruction must also be taken into account. Unfortunately, because of its inert biological behavior, it undergoes progressive resorption, with frequent fracture. Several attempts have been made to induce new vascularization in massive bone allograft, with poor results. However, neo-angiogenesis was reported with vascular loops, and we therefore hypothesized that heterologous graft integration could be enhanced by creating a vascular loop through the graft. A 50-year-old male with chondrosarcoma of the ring finger of the left hand underwent wide resection. An allogenic middle phalanx of comparable size was then prepared to fill the defect. Two small windows were performed proximally and distally on the radial surface of the allogenic phalanx, and a 4 cm-long vein graft was inserted inside the medullary canal. Metacarpophalangeal joint stability was achieved by collateral ligament reconstruction with micro-anchors. The distal part of the allograft was then stabilized to the middle phalanx with a 1.5 mm-thick micro-plate and screws. The radial proper palmar digital artery was proximally and distally sutured end-to-end to the vein graft, under microscopy. At 12-month follow-up, the allograft was fused, and histology performed at plate removal at 18 months revealed viable spindle cells with osteoblastic differentiation, without evidence of atypia, in a dense fibrous stroma. At 22 months' follow-up, the patient was apparently disease-free, and satisfied with his manual function., (Copyright © 2022 SFCM. Published by Elsevier Masson SAS. All rights reserved.)

Ulnar tunnel syndrome is the second most common upper-limb peripheral nerve compression syndrome. Recurrence or persistence of symptoms after primary surgery is found in 9.9%-21% of cases. The main cause of failure is peri- and endo-neural fibrosis, and management is difficult and controversial. Revision of nerve neurolysis combined with freestyle adipofascial flap provides nerve decompression and coverage with vascularized tissue, which prevents scar tissue formation around the nerve and restores glide. We performed a preliminary vessel-injected cadaver study. The perforating vessels from the posterior recurrent ulnar artery vascularize the medial adipose and fascial tissues of the elbow, allowing elevation of an adipofascial flap which is able to reach the ulnar nerve. Eight patients with neuropathic ulnar nerve pain in recalcitrant ulnar tunnel syndrome due to peri- and/or endo-neural fibrosis were treated by neurolysis, and the nerve was covered with an ulnar adipofascial flap. All patients were evaluated by percussion test, visual analog scale for pain, electromyography, electroneurography and ultrasound, and were classified according to the McGowan classification as modified by Goldberg. The study was approved by the review board. All patients had good 4-year outcome, with complete return to daily activity, work and sports 4 months after surgery. The results of this novel surgical technique were encouraging, without complications or donor site morbidity. Adipofascial flap combined with neurolysis could be a valid solution in the treatment of recalcitrant ulnar tunnel syndrome., (Copyright © 2021 SFCM. Published by Elsevier Masson SAS.

Objective: Osteoporosis is a highly prevalent disease worldwide. Consequences of vertebral osteoporotic fractures include pain and progressive vertebral collapse resulting in spinal kyphosis, decreased quality of life, disability and mortality. Minimally invasive procedures represent an advance to the treatment of osteoporotic VCFs. Despite encouraging results reported by many authors, surgical intervention in an osteoporotic spine is fraught with difficulties. Advanced patients age and comorbidities are of great concern., Patients and Methods: We designed a retrospective case-control study on 110 post-menopausal women consecutively visited at our institution. Study population was split in a surgical and a conservative cohort, according to the provided treatment., Results: Kyphoplasty treated patients had lower back pain VAS scores at 1 month as compared with conservatively treated patients (p < 0.05). EQ5D validated questionnaire also showed a better quality of life at 1 month for surgically treated patients (p < 0.05). SF-12 scores showed greater improvements at 1 month and 3 months with statistically significant difference between the two groups just at 3 months (p < 0.05). At 12 months, scores from all scales were not statistically different between the two cohorts, although surgically treated patients showed better trends than conservatively treated patients in pain and quality of life. Kyphoplasty was able to restore more than 54.55% of the original segmental kyphosis, whereas patients in conservative cohort lost 6.67% of the original segmental kyphosis on average., Conclusions: Kyphoplasty is a modern minimal invasive surgery, allowing faster recovery than bracing treatment. It can avoid the deformity in kyphosis due to VCF. In fact, the risk to develop a new vertebral fracture after the first one is very high.
