Ulnar nerve anteposition with adipofascial flap, an alternative treatment for severe cubital syndrome.

BACKGROUND: Ulnar nerve entrapment at the elbow is the second most common cause of nerve entrapment in the upper limb. Surgical techniques mainly include simple decompression, decompression with anterior transposition and medial epicondylectomy. METHODS: We performed decompression with anterior transposition and protected ulnar nerve by adipofascial flap (a random flap with radial based vascularization, harvested through the avascular plane of Scarpa's fascia. We analyzed patients who underwent ulnar nerve ante-position from 2015 to 2022 according to inclusion and exclusion criteria for a total of 57 patients. All patients included were graded on the McGowan's classification Messina criteria and the British Medical Research Council modified by Mackinnon and Dellon. RESULTS: The average McGowan's score was 2.4 (± 0.6), Messina's criteria 91.2% indicated a satisfactory or excellent result, sensibility at 6 months was 98.5% S3 or more. A preferential technique has not yet been defined. CONCLUSIONS: The adipofascial flap offers numerous advantages in providing a pliable, vascular fat envelope, which mimics the natural fatty environment of peripheral nerves and creates favorable micro-environmental conditions to contribute to neural regeneration via axon outgrowth.

Stem Cells in Autologous Microfragmented Adipose Tissue: Current Perspectives in Osteoarthritis Disease.

Osteoarthritis (OA) is a chronic debilitating disorder causing pain and gradual degeneration of weight-bearing joints with detrimental effects on cartilage volume as well as cartilage damage, generating inflammation in the joint structure. The etiology of OA is multifactorial. Currently, therapies are mainly addressing the physical and occupational aspects of osteoarthritis using pharmacologic pain treatment and/or surgery to manage the symptomatology of the disease with no specific regard to disease progression or prevention. Herein, we highlight alternative therapeutics for OA specifically considering innovative and encouraging translational methods with the use of adipose mesenchymal stem cells.

A Hemi-Hemi-Hamate Osteochondral Graft: A Modified Hemi-Hamate Technique for a Unicondylar Defect.

Articular comminuted fracture dislocations of the base of the middle phalanx represent a major challenge for the surgeon. The treatment goal is a nonpainful, stable, and functional proximal interphalangeal joint, which is achieved through concentric joint reduction and restoration of joint stability. Fracture pattern rarely results in sagittal bone loss involving the entire ulnar or radial pilon of the base of the second phalanx. In these cases, the choice of treatment can be particularly challenging as the loss of a pillar of the articular base causes angular deviation at the joint level, thus causing the loss of finger joint flexion and overlap of the adjacent finger. We present a novel nonvascularized osteochondral graft, which we named hemi-hemi-hamate osteochondral graft, a modified version of the traditional hemi-hamate arthroplasty, that is suitable for the reconstruction of bone loss involving the whole anteroposterior hemiarticular surface of the base of the P2.

Hand Trauma and Reconstructive Microsurgery during the COVID-19 Emergency in the Marche Region (Italy): What Has Changed?

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing COVID-19, has spread across the globe. To limit the spread of COVID-19, the Italian government imposed various restrictions (lockdowns). These restrictions had an impact on the flow of patients accessing hospital care. Our aim in this study was to analyze the impact of lockdowns on the epidemiology of patients suffering from hand trauma. Our work analyzed the variation in the number and characteristics of hand trauma patients during the lockdown and half-lockdowns in 2020 compared to the same periods in the previous and subsequent years. In 2020, during the lockdown period, 107 patients were treated by our department for hand trauma, amounting to a 2% increase compared to the average number of patients treated in the pre-pandemic period. In 2020, during the half-lockdown period, 158 patients were treated, amounting to a 6.8% increase in comparison to the pre-pandemic period. During the lockdown period in Italy, the flow of patients suffering from hand trauma referred to our hub center remained stable. Given the restrictions imposed by the lockdown, we expected a consequent reduction in the number of work-related injuries, which did occur, while there was a surprising increase in the number of traffic-related injuries. The number of domestic accidents remained stable.

A Large Osteoid Osteoma of Trapezium: A Regenerative Approach and a Review of Literature.

Osteoid osteoma is a benign bone tumor that usually grows in the long bones of the body and arises from osteoblasts and some components of osteoclasts. It represents the third most frequent type of benign bone tumors, accounting for 11% to 14% of the tumors. The entity usually involves the proximal femur and tibia. It has also been reported in the hand, especially the scaphoid, capitate, and proximal phalanx. The most common symptom is pain, usually during the night, relieved by the use of salicylates and nonsteroidal anti-inflammatory drugs. To date, only 5 cases involving the trapezium have been reported. This article describes a rare case of a large (1.3 cm) osteoid osteoma of the trapezium in a young male patient treated surgically with resection and curettage of the osteoid and provides a review of the existing literature.

Biophysical Stimulation in Delayed Fracture Healing of Hand Phalanx: A Radiographic Evaluation.

Phalangeal fractures are common events among the upper limbs accounting for 10% of all human body fractures. Fracture complete healing process may persevere several months or years. Most phalangeal fractures present favorable union within 3 to 6 weeks. In the literature, biophysical stimulation has yielded favorable outcomes in the treatment of hand fractures. A survey involving hospitals in the US reported the use of biophysical stimulation (72%) in relation to nonhealing fractures at three months after trauma. A noninvasive procedure such as biophysical stimulation may be preferential prior to consideration of invasive procedures. In this retrospective study, we analyzed 80 phalangeal fractures, 43 of which did not show any radiographic sign of healing 30 days after surgery; on radiograms, we calculated radiographic data and the total active motion (TAM) for clinical comparison. All radiographic images were evaluated using Adobe Photoshop CS3 (version 10.0, Adobe Systems Inc., San Jose, CA, USA). We calculated the index of relative bone healing each month after surgery starting from 30 days, which was considered as T1, and followed up for a total of 6 months after stimulation (T6) with better results in stimulated groups. We concluded that prompt administration of biophysical stimulation supports fracture healing and yields an important improvement in the union rate compared with nontreatment. Above all, our patients experienced less injury-related distress between the fracture and repair period, which consequently reduced immobilization time, envisaging an early rehabilitation interval, with a better patient hand outcome.

A case report of upper limb loss of substance: Use of functional gracilis free flap, brachioradialis transposition and bioglass for bone regeneration.

Complex trauma of the upper limb is a common consequence of involvement in serious accidents. Loss of substance including nerve, bone, tendons and vascular defects are challenging surgical issues. A 27- year-old male presented with complex upper limb trauma and loss of a proximal third of the posterior forearm structure as well as loss of active finger extension, ulnar and radial nerve territory anesthesia and ulnar fracture. A composite nerve-tendon-muscle-skin gracilis free flap was retrieved from the contralateral leg, related to tendon transfer of BR to ELP, to supply active hand extension. The patient was required to adhere to intensive post-surgical rehabilitation and monitored for a 3-year follow-up period. Our assessment revealed adequate skin trophism and sufficient muscle strength recovery against resistance (M5). The functional flap associated with tendon transfer was considered an efficient procedure for the management of a complex trauma with loss of posterior interosseous nerve and bone exposition. The free re-innervated gracilis flap may be used to repair complex soft tissue defects with exposed bone and to restore finger extension following severe forearm injuries.

A Peculiar Case of Open Complex Elbow Injury with Critical Bone Loss, Triceps Reinsertion, and Scar Tissue might Provide for Elbow Stability?

BACKGROUND: Complex elbow injuries (CEIs) are severe and rare lesions, difficult to treat correctly due to the different patterns of clinical presentations. Standard methods cannot often be applied. The main goals of the treatment are performing a stable osteosynthesis of all fractures, obtaining a concentric and stable reduction of the elbow by repairing the soft tissue constraint lesions, and allowing early motion. Since the introduction of virtual reality (VR) approaches in clinical practice, three-dimensional (3D) computed tomography (CT) and 3D printing have revolutionised orthopaedic surgeries, thus helping to understand the anatomy and the pathology of complex cases. CASE DESCRIPTION: We discussed a case of CEI, characterised by an extended soft tissue (IIIB Gustilo classification) and neurovascular lesions associated with bone loss in a young female patient. Olecranon fracture was type IIIB according to Mayo classification. We outlined the steps of a pluri-tissue reconstructive approach and stressed the importance of 3D printing in the preoperative planning for such cases. Finally, peculiar final functional patient outcomes were reported. CONCLUSION: In this case, we found out that triceps reinsertion and scar process may provide for the joint stability in a low-demanding patient. 3D printing and VR approaches in clinical practice can be useful in the management of CEIs associated with an important bone and soft tissue loss.
