Background: Peripheral nerve injuries (PNIs) of the upper limb are very common events within the pediatric population, especially following soft tissue trauma and bone fractures. Symptoms of brachial plexus nerve injuries can differ considerably depending on the site and severity of injury. Compared to median and radial nerves, the ulnar nerve (UN) is the most frequently and severely injured nerve of the upper extremity. Indeed, due to its peculiar anatomical path, the UN is known to be particularly vulnerable to traumatic injuries, which result in pain and substantial motor and sensory disabilities of the forearm and hand. Therefore, timely and appropriate postoperative management of UN lesions is crucial to avoid permanent sensorymotor deficits and claw hand deformities leading to lifelong impairments. Nevertheless, the literature regarding the rehabilitation following PNIs is limited and lacks clear evidence regarding a solid treatment algorithm for the management of UN lesions that ensures full functional recovery. Case presentation: The patient is a 11-year-old child who experienced left-hand pain, stiffness, and disability secondary to a domestic accident. The traumatic UN lesion occurred about 8 cm proximal to Guyon's canal and it was surgically treated with termino-terminal (end-to-end) neurorrhaphy. One month after surgery, the patient underwent multimodal rehabilitative protocol and both subjective and functional measurements were recorded at baseline (T0) and at 3- (T1) and 5-month (T2) follow-up. At the end of the rehabilitation protocol, the patient achieved substantial reduction in pain and improvement in quality of life. Of considerable interest, the patient regained a complete functional recovery with satisfactory handgrip and pinch functions in addition with a decrease of disability in activities of daily living. Conclusion: A timely and intensive rehabilitative intervention done by qualified hand therapist with previous training in the rehabilitation of upper limb neuromuscular disorders is pivotal to achieve a stable and optimal functional recovery of the hand, while preventing the onset of deformities, in patients with peripheral nerve injuries of the upper limb.
RESUMEN
Scapholunate advanced collapse collapse (SLAC) is a challenging topic for hand surgeons. The adaptative proximal scaphoid implant (APSI) (Bioprofile-Tornier) is a pyrocarbon ovoid shaped interpositional implant, that allows adaptive mobility during motion. The aim of this systematic review is to analyze the clinical and radiological outcomes of APSI implants and possible complications. We performed a literature search combining the following key-words: "APSI", "Scaphoid's proximal pole", "implant", "scaphoid avascular necrosis", "SLAC", "SNAC", "pyrocarbon", "prosthesis", and "spacer" with no limitations for year of publication. We selected seven studies considered relevant to our systematic review. All studies described an improvement in the grip strength and the flexion extension arch compared to pre-operative values. The percentage of patients who reported progression of osteoarthritis (OA) with APSI was 17.3%, and implant's mobilization has a rate 5.1% (8/156). In conclusion the APSI implant is a reliable alternative for the treatment of SNAC wrist and SLAC wrist.
RESUMEN
PURPOSE: Volar rim fractures of the distal radius are a spectrum of pathology that must be well identified and treated to achieve good outcomes and avoid surgical failures. New devices of fragment specific fixation have been developed during the last decades to fix this fragment. The purpose of this retrospective study was to evaluate the ability of APTUS® wrist distal radius system to securely fix different types of volar rim fractures. METHODS: Patients with at least 1 year of follow-up and a preoperative CT-scan evaluation of the fracture pattern were included in the study. Clinical, radiological and functional outcomes were assessed. RESULTS: Sixty-eight patients with an average follow-up of 34, 1 months (12-61) were included in the study. There were no clinical and radiological complications, including loss of reduction, device failure and tendon ruptures. No patients required hardware removal. Wrist range of motion in flexion-extension averaged 96°, while in pronation-supination 144°. At final follow-up mean visual analogue scale pain was 1,8. Questionnaires, as dissabilities of the arm, shouldder and hand (DASH) score and patient-related wrist evolution (PRWE) score were 6,6 and 3 respectively. Grip strenght measured 86% compared to the normal side. CONCLUSION: APTUS® wrist presents a versatile set of fragment specific fixation plates able to easily and securely fix all types of volar rim fracture. The system can be used with other devices without any kind of interference between them. When correctly placed and used with the right indications, no late complications can be recorded.

We report the outcomes of delayed primary repair of flexor tendons in Zone 2 in 31 fingers and thumb (28 patients) averaging 15 days (range 4-37) after injury in 2020. The delay was longer than usual due to the COVID-19 pandemic. The tendons were repaired with a 6-strand core suture (M-Tang method) or a double Tsuge suture and a peripheral suture. This was followed by an early, partial-range, active flexion exercise programme. Adhesions in four digits required tenolysis. These patients were not with longest delay. Outcomes of two improved after tenolysis. The other two patients declined further surgery. One finger flexor tendon ruptured in early active motion. This was re-repaired, and final outcome was good. Overall excellent and good results using the Tang criteria were in 27 out of 31 fingers and thumbs (87%). The time elapsed between the injury and surgery is not an important risk factor for a good outcome, rather it depends on proper surgical methods, the surgeon's experience and early mobilization, properly applied. Adhesions may occur, but they can be managed with tenolysis.Level of evidence: IV.

BACKGROUND: Carpal bone lesions are common, even in acute injuries or as sequalae of missed fractures. If not correctly diagnosed and treated, can lead to loss of function, especially in active patients. The surgical management remain difficult particularly in case of small, atypical or non-unions fragments. The treatment of heterogenic shape fractures should require a fragment specific fixation using, traditionally, Kirschner-wire (K-wire). This method of treatment remains the most popular but could be prone to some complication as: not stable fixation, need to long time immobilization and wire mobilization. Methods Nineteen patients presented with carpal bone lesions were treated by the use of HCS 1,5 mm headless compression screws. Patients were evaluated post-operative by Patient-Rated Wrist Evaluation (PRWE), the Visual Analogic Scale (VAS), Quick-DASH Score and the grip strength was measured by Jamar dynamometer. RESULTS: Authors observed improvement of pain control and common activity; fine movements were restored; we observed no post-operative functional instability. CONCLUSIONS: HCS 1,5 mm headless compression screws are suitable and smart technique to treat these uncommon fractures to achieve a stable primary fixation and allow an early mobilization and conciliate the versatility of K-wire and the compression action due to screws also in small bone fragment.
RESUMEN
Surgical treatment of extra-articular metacarpal and phalangeal fractures should be considered when there is instability or in patients with high demand. To overcome the issues related to the use of Kirschner wires, external fixators, and open reduction and internal fixation procedures, intramedullary headless screw fixation (IHSF) is an alternative technique to achieve primary fracture stability and early return to daily activities. We report the data of the Italian Multicentric Intra-Medullary Experience, which includes 173 cases of extra-articular unstable fractures (38 phalanges and 135 metacarpals) treated with the IHSF. After surgery, patients underwent early mobilization without splinting. The results confirm the reliability of IHSF in cases with non-articular involvement, showing a good recovery rate in terms of bone healing and range of motion.Level of evidence: IV.

BACKGROUND: the purpose is to gather and analyze the statistical datas of wrist and hand injuries admitted to the Hand and Reconstructive Microsurgery and Replantation Hub center of Careggi Hospital, Florence during the first two months of COVID-19 epidemic in Italy. The Authors investigated how the drastic changes in daily activities modified the epidemiology of hand trauma lesions. METHODS: The Authors analyzed the characteristics of hand and wrist traumatic disorders during the months of February and March comparing 2019 to 2020. Collected data included age distribution, traumatic etiology, diagnosis and type of surgical procedures. RESULTS: The total number of orthopedic and trauma patients significantly decrease in 2020 compared to 2019 (3360 vs 1470). The number of hand and wrist injuries didn't show a significant difference between 2019 and 2020 instead (192 vs 131). The overall number of patients hospitalized and surgically treated at our Operative Unit (OU) was 168 in 2019 and 120 in 2020. Male patients resulted prevalent (60,7 M vs 39,3F/2019; 63,2 M vs 36,8F/2020). In terms of patient age, in 2020 we registered a significant reduction of cases in the 20-35-year-old age group and a significant increase in the 51-65 and 66-80-year-old age groups. Traffic-related, sport-related and fortuitous injuries significantly decreased in 2020, while the number of domestic accidents significantly increased. Analyzing the Hospital Discharge Records (HDR), we found a significant increase in the number of proximal and middle phalanx fractures; no significant differences were found for other kinds of discharge diagnosis. As for the choice of surgical treatment options, no differences were found between 2019 and 2020. CONCLUSION: Even during drastic movement restrictions and the prolonged suspension of work and leisure activities secondary to COVID-19 epidemic in 2020, hand and wrist traumas rate remained almost the same compared to the same period of the previous year. Nevertheless, a significant change in the etiology and patient age was registered. In fact, sport and traffic-related traumas decreased respect to domestic traumas, while the previous prevalent involvement of young adults was surpassed by accidental hand traumas in the elderly and active adults.
RESUMEN
BACKGROUND: Ulnar nerve lesions represent a rare complication of wrist fracture. The present manuscript describes the case of a particular traumatic mechanism in which the nerve resulted crushed between radial fracture fragments. CASE PRESENTATION: A 47-year-old man suffered a subtotal lesion of the ulnar nerve following an open displaced distal radius fracture. Symptoms of ulnar nerve deficiency worsened after reduction and temporary stabilization. Further surgery was performed to achieve definitive stabilization and ulnar nerve neurolysis. The ulnar nerve was found to be jammed inside the fracture side, and so was repaired with a direct suture. Progressive recovery was observed in the following months. CONCLUSIONS: Given the paucity of reports of ulnar nerve injury in the literature, clear recommendations for treatment of nerve lesions after wrist fractures have not yet been defined. Nevertheless, in our experience, peripheral nerve function should be assessed before and after fracture reduction, as a worsening of symptoms after surgical intervention could indicate nerve entrapment inside the fracture site.
RESUMEN
With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown. Ten surgeons critically construed and interpreted the data to form rationale guidelines and recommendations. Of the total, hand and microsurgery surgeons (52%), trauma surgeons (32%), joint replacement surgeons (20%), and arthroscopy surgeons (14%) actively participated in the survey. Surgeons from national public health care/government college hospitals (44%) and private/semiprivate practitioners (54%) were involved in the study. Countries had lockdown started as early as January 3, 2020 with the implementation of partial or complete lifting of lockdown in few countries while writing this article. Surgeons (58%) did not stop their surgical practice or clinics but preferred only emergency cases during the lockdown. Most of the surgeons (49%) had three-fourths reduction in their total patients turn-up and the remaining cases were managed by conservative (54%) methods. There was a 50 to 75% reduction in the number of surgeries. Surgeons did perform emergency procedures without COVID-19 tests but preferred reverse transcription polymerase chain reaction (RT-PCR; 77%) and computed tomography (CT) scan chest (12%) tests for all elective surgical cases. Open fracture and emergency procedures (60%) and distal radius (55%) fractures were the most commonly performed surgeries. Surgeons preferred full personal protection equipment kits (69%) with a respirator (N95/FFP3), but in the case of unavailability, they used surgical masks and normal gowns. Regional/local anesthesia (70%) remained their choice for surgery to prevent the aerosolized risk of contaminations. Essential surgical follow-up with limited persons and visits was encouraged by 70% of the surgeons, whereas teleconsultation and telerehabilitation by 30% of the surgeons. Despite the protective equipment, one-third of the surgeons were afraid of getting infected and 56% feared of infecting their near and dear ones. Orthopaedic surgeons in private practice did face 50 to 75% financial loss and have to furlough 25% staff and 50% paramedical persons. Orthopaedics meetings were cancelled, and virtual meetings have become the preferred mode of sharing the knowledge and experiences avoiding human contacts. Staying at home, reading, and writing manuscripts became more interesting and an interesting lifestyle change is seen among the surgeons. Unanimously and without any doubt all accepted the fact that COVID-19 pandemic has reached an unprecedented level where personal hygiene, hand washing, social distancing, and safe surgical practices are the viable antidotes, and they have all slowly integrated these practices into their lives. Strict adherence to local authority recommendations and guidelines, uniform and standardized norms for admission, inpatient, and discharge, mandatory RT-PCR tests before surgery and in selective cases with CT scan chest, optimizing and regularizing the surgeries, avoiding and delaying nonemergency surgeries and follow-up protocols, use of teleconsultations cautiously, and working in close association with the World Health Organization and national health care systems will provide a conducive and safe working environment for orthopaedic surgeons and their fraternity and also will prevent the resurgence of COVID-19.
RESUMEN
Background: Complex periarticular fractures of the metacarpophalangeal joint (MCPJ) are often challenging to treat. Conservative and operative treatments are often burdened with stiffness, loss of function, and poor clinical outcome. These phenomena could be a direct consequence of long period of immobilization. To promote a short time of immobilization and a quick return to daily activities, it is mandatory to stabilize the fracture maintaining the active range of motion (AROM) of the ray. A simple solution is to reduce the fragments by means of dynamic ligamentotaxis. The authors propose a new dynamic distraction device (DDD) for the MCPJ. Methods: The DDD for the MCPJ was made of Kirschner wires bent and connected to counteract dislocation forces and to allow mobilization of the joint. The DDD was tested on a cadaver model under a simulated load in physiological conditions, and also in metacarpal and proximal phalanx (P1) fracture patterns. The effectiveness of the device was evaluated under fluoroscopy. Results: The data showed that DDD is able to achieve fracture reduction through ligamentotaxis and primary fragments stability and to avoid secondary dislocation during AROM of complex periarticular fractures of the MCPJ. Conclusions: The frame could be an alternative option to treat periarticular fractures of the MCPJ. The DDD implant has several advantages: It is time efficient because assembly and application take only few minutes. Furthermore, it is very versatile; indeed, it can be used in all metacarpal and phalanx bones, even in the central rays.

BACKGROUND: Dorsal complex cutaneotendinous lesions of the hand represent a reconstructive challenge. The use of composite microvascular flaps and vascularized tendon grafts represent the gold-standard. The radial anti-brachial region can still represent an excellent donor site, to the detriment of the possible sacrifice of the radial artery. The reverse radial anti-brachial flap can be either perforator-based, thus saving the radial artery or raised as an adipo-fascial flap, to spare the skin. PATIENTS AND METHODS: A case of post-traumatic highly contaminated dorsal cutaneotendinous defect of the second ray of the hand was reported. An original surgical reconstructive technique with a Revers Radial Teno-Adipo-Fascial Flap (RRTAFF) plus vascularized Palmaris Longus was described, preserving the radial artery. A simple partial thickness skin graft was performed a second time to complete dorsal cutaneous coverage. A subsequent infection was managed by trusting the complete vascularization of the tissues used for the reconstruction. RESULTS: The hand healed well with containment of the infection. The dorsal healed skin appeared elastic and pliable enough. Passive and active motion of interphalangeal and metacarpofalangeal joints were very satisfying. The donor site was well healed, with almost no morbidity. CONCLUSIONS: This reconstructive strategy provides a quick and straightforward single-stage option for the reconstruction of complex cutaneotendinous defects of the dorsum of the hand. Such a reconstruction, with a completely vascularized procedure, is particularly indicated in cases of high contamination or infection of the recipient site.

Anterior dislocation of a prosthetic knee is a rare event. Only few episodes have been described in the past and have never been linked with neurovascular injury. This could lead orthopaedic surgeons to focus on the implant instability factors and underrate other complications. The authors report a case of a patient who experienced popliteal artery dissection 80 hours after traumatic anterior knee dislocation of a previously well-functioning total knee arthroplasty. Given that there is a lack of clinical cases that have established guidelines for management of this problem, the authors have focused on the importance of performing computed tomography angiography in the management of an anterior traumatic knee dislocation of a prosthetic knee.
RESUMEN
Metacarpal fractures constitute 7.8% of the upper extremity fractures. The common treatments remain nonsurgical procedure, but high-demanding patients or unstable fractures require fixation with Kirschner wire (K-wires), plate, and screws. However, these approaches may cause scarring and adhesion with poor functional results. From 2014 to 2015, the authors used an intramedullary headless screw to treat 25 patients (24 men, 1 woman) with metacarpal bones fractures (20 V, 3 IV, 1 III, and 1 II). The fractures patterns were 23 fractures of distal third of metacarpal bone (16 oblique, 5 comminute configurations, and 2 transverse), 1 fracture of the base of the II metacarpal bone. One case presented a multiple metacarpal and phalangeal facture associated. The authors used wide-awake anesthesia (bupivacaine-epinephrine 1:100,000) and intramedullary titanium headless screw fixation percutaneously inserted (CCS Medartis and HCS Synthes 3 mm of diameter). No open reduction was needed. Early active mobilization started with a buddy strapping soon after surgery (0-3 days). The authors followed all patients until satisfactory function was achieved (4-6 weeks) and recorded the time till return to work. All fracture healed with less than 5 degrees of rotational or axial deformities. All patients return to work within 2.38 weeks after surgery (0.5-6 weeks). No cases of complex regional pain syndrome (CRPS), tendon lesions, nerve injuries, infection, hardware protruding, or mobilization were reported. Intramedullary screw fixation with wide-awake anesthesia for transverse, oblique, and select comminuted fractures treatment metacarpal fractures represent a reliable option to early active mobilization recovery and a quick return to the work and ordinary activities.
RESUMEN
The purpose was to establish a ranking of the 50 most cited articles about wrist surgery and analyse their features. Science Citation Index Expanded was used to identify the 50 most frequently cited orthopaedic journal articles written in English, searching for the topic "wrist surgery" in the subject category ''Orthopaedics''. Then, we analysed the number of citations, citation density, authorship, article institution, the year of publication, the country of origin of the article, name and impact factor of the journal, and publication type of the article. The 50 most cited articles were published in only 6 of the 74 journals included under the category "orthopaedics". Citation count ranged from 256 for the first one to 67 for the 50th article. Most of them were written by American authors. These articles were published between 1991 and 2011. "Distal Radius Fractures" was the most common issue. This type of bibliographic analysis could be particularly useful for other young Authors who would like to improve their research in wrist and hand surgery and make their publications more citable and appreciated by the scientific community.
RESUMEN
Currently, the gold standard to repair large nerve defects is the autologous nerve graft. These solutions offer a mechanical support, adhesion substrates, and, with Schwann cells (SC), a source of neurotropic factors for axonal growth. The technical limits are the donor side damage, multiple surgical accesses, and the unavailability of large amounts of grafts. In recent years, several researchers focused their attention on the interaction between cells (nervous and glial) and physic-chemical cues that arise from the extracellular milieu. Nanotechnologies produce surfaces that mimic the topographical signals (physical stimuli) that arise from enterprise content management (ECM) to modulate the forces acting during axonal elongation. The use of magnetic nanoparticles (MNPs) seems to be able to guide and to boost the nerve regeneration. Both research areas could be improved through surfaces functionalization by biological molecules (proteins/peptides, growth factors, etc.). In the future, the aim will be to help recovery after peripheral nerve lesion by producing a tridimensional structured conduit, then repeat the ECM architecture and take advantage of MNPs internalized by cells and guide them through tension forces by external magnetic fields to stimulate and direct axon growing. The aims of this review were to evaluate the findings of studies that used physical stimuli (nanoscaffold surfaces and MNPs) used for peripheral nerve regeneration support. The future trends in the field of peripheral nerve regeneration continue to produce a wide variety of new techniques to improve the opportunity for advances to treat peripheral nerve injuries.
