RESUMEN
BACKGROUND: Several surgical techniques have been reported for flexor tendon zone 1a-b lacerations without a clear consensus on the gold standard treatment. The purpose of this multicentre study was to measure the outcomes of zone 1a-b flexor tendon injuries treated with a pull-out suture (POS) versus direct suture (DS) technique. PATIENTS AND METHODS: Fifteen patients were treated with the pull-out technique and 22 patients with a direct suture technique between 2014 and 2020. The controlled active motion (CAM) regimen protocol and a standardised follow-up schedule were used in both groups. Data on the demographics, surgery, and treatment characteristics were collected at baseline as well as at week 6 and 13 post-operatively. The primary outcome measurement was the complication rate. Secondary outcome measurements were reoperation rate, finger range of motion (ROM), strength as well as patient satisfaction. RESULTS: The patient age ranged from 18 to 75 years in both groups with all patients having a complete FDP lesion after a clean-cut injury. The complication rate was 41% in the POS group and 16% in the DS group. The reoperation rate was 29% in the POS group and 8% in the DS group. Significant between-group differences in favour of the DS group were found in the passive DIP and passive PIP+DIP ROM at week 6 and week 13. Mean hand strength was 28.7 (11.6) kg in the POS group at week 13 and 21.3 (7.9) kg in the DS group. This difference was statistically significant (p=0.012) with a medium effect size (r=-0.41). Average patient satisfaction at week 13 was 7.5 (2.2) points in the POS and 7.7 (1.3) points in the DS group. The difference between groups was not significant (p=0.839). CONCLUSION: This register-based study demonstrates lower complication and reoperation rates with the direct suture approach compared with a pull-out button technique. Although clinical results were similar between the two surgery techniques at week 13 post-surgery, a direct suture approach should always be attempted whenever possible. If necessary, other local structures should be included to increase suture strength and allow for early active motion rehabilitation regimens.
RESUMEN
The Questionnaire for Patient-Surgeon Relationship (Q-PASREL) is a French "Patient-Reported Experience Measure" for hand surgery patients. It is the only one which considers the impact of the patient-surgeon relationship on time to return to work and cooperation by the surgeon for administrative issues. It has been shown that a good Q-PASREL score is associated with shorter sick leave and faster return to work. To make this instrument available to more countries, we translated the Q-PASREL into six languages (English, Spanish, German, Italian, Arabic and Persian), following a validated "translation and cultural adaptation" process guideline. This process includes multiple forward and backward translations, discussions and reconciliations with final harmonization and cognitive debriefing. For each language, a team was set up, comprising a key in-country hand surgery consultant, native target-language speaker and fluent in French, and several forward and back translators. The final translated versions were reviewed and approved by the project manager. The six versions of Q-PASREL are now available in the appendices of this publication.

Introduction: Metatarsal stress fractures typically occur in the second and third metatarsus metaphysis, with only rare cases in the fourth and first. The main factors influencing its onset are repetitive stress from prolonged training, biomechanical factors and bone weakness. There is only a paucity of literature documenting first metatarsal stress fractures; the authors present a rare bilateral first metatarsal stress fracture. Case Report: A Caucasian 52-years-old amateur female runner with no other risk factors or medical condition was admitted in our institute with complaints of severe bilateral forefoot pain for 2 weeks arisen after a 20 km run of an amateur race. The patient presented bilateral hallux valgus (HVA) and advanced osteoarthritis of the first metatarsal-phalangeal joint, which is not usually considered a biomechanical risk factor for metatarsal stress fractures. Radiographs of both feet showed linear sclerosis, perpendicular to the diaphysis of the first metatarsal, approximatively in the half of the bone. Signs of osteoarthritis of the first metatarsal-phalangeal were also detected bilaterally.The patient was treated with rest, bilateral post-operative rocker sole shoes that she has worn for 6 weeks, cryotherapy, analgesics as needed and pulsed electromagnetic fields for 8 h per day for 40 days with a complete resolution of symptoms and the previous radiological findings. Conclusion: The authors believed that the bilateral HVA condition could be considered an indirect sign of overuse, and it may be investigated and eventually treated as a responsible for this pathologic condition.
RESUMEN
Introduction The purpose of the study was to evaluate the results of treatment of the nonunion of long bones using nonvascularized iliac crest grafts (ICGs) or vascularized bone grafts (VBGs), such as medial femoral condyle corticoperiosteal flaps (MFCFs) and fibula flaps (FFs). Although some studies have examined the results of these techniques, there are no reports that compare these treatments and perform a multifactorial analysis. Methods The study retrospectively examined 28 patients comprising 9 women and 19 men with an average age of 49.8 years (range: 16-72 years) who were treated for nonunion of long bones between April 2007 and November 2018. The patients were divided into two cohorts: group A had 17 patients treated with VBGs (9 patients treated with MFCF and 8 with FF), while group B had 11 patients treated with ICG. The following parameters were analyzed: radiographic patterns of nonunion, trauma energy, fracture exposure, associated fractures, previous surgeries, diabetes, smoking, age, and donor-site morbidity. Results VBGs improved the healing rate (HR) by 9.42 times more than the nonvascularized grafts. Treatment with VBGs showed a 25% decrease in healing time. Diabetes increased the infection rate by 4.25 times. Upper limbs showed 70% lower infection rate. Smoking among VBG patients was associated with a 75% decrease in the HR, and diabetes was associated with an 80% decrease. Conclusion This study reports the highest success rates in VBGs. The MFCFs seem to allow better clinical and radiological outcomes with less donor-site morbidity than FFs.
RESUMEN
Purpose: The biomechanical characteristics of different techniques to perform the modified Lapidus procedure are controversial, discussing the issue of stability, rigidity, and compression forces from a biomechanical point of view. The aim of this systematic review was to investigate the available options to identify whether there is a procedure providing superior biomechanical results. Methods: A comprehensive literature search was performed by screening PubMed, Embase, and Cochrane databases until September 2021. There was a wide heterogeneity of the available data in the different studies. Load to failure, stiffness, and compression forces were summarized and evaluated. Results: Seventeen biomechanical studies were retrieved - ten cadaveric and seven polyurethane foam (artificial bone) studies. Fixation methods ranged from the classic crossed screw approach (n = 5) to plates (dorsomedial and plantar) with or without compression screws (n = 11). Newer implants such as intramedullary stabilization screws (n = 1) and memory alloy staples (n = 2) were investigated. Conclusion: The two crossed screws construct is still a biomechanical option; however, according to this systematic review, there is strong evidence that a plate-screw construct provides superior stability especially in combination with a compression screw. There is also evidence about plate position and low evidence about compression screw position. Plantar plates seem to be advantageous from a biomechanical point of view, whereas compression screws could be better when positioned outside the plate. Overall, this review suggests the biomechanical advantages of using a combination of locking plates with a compression screw.
RESUMEN
Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

PURPOSE: Trapeziectomy has frequently been used to treat basal thumb osteoarthritis. However, complications, such as shortening of the thumb ray and reduced mobility and strength, can occur. The aim of this study was to present a 10-year follow-up of distraction arthroplasty without trapeziectomy. METHODS: Fifteen patients were followed for a mean of 121 months (range, 121-124 months). Subjective outcomes were evaluated with the Disabilities of the Arm, Shoulder, and Hand questionnaire, while the pain intensity was assessed with a Visual Analog Scale both before surgery and at the end of follow-up. Objective outcomes were obtained using the Kapandji score and an assessment of grip and pinch strength. Preoperative and final postoperative x-rays were obtained to evaluate metacarpal subsidence and progression of trapezial-metacarpal joint arthritis. RESULTS: The Visual Analog Scale score was reduced from 9.4 ± 0.5 before surgery to 2.5 ± 1 at follow-up. The mean Disabilities of the Arm, Shoulder, and Hand questionnaire score was 75.6 ± 12.6 before surgery and 16.9 ± 4 at 10 years. Hand grip strength of the operated side (26 ± 5.5 kg) achieved 95% of functionality compared to the opposite side, while key pinch strength (6.4 ± 1.6 kg) reached 93%. A Kapandji opposition score of 10 points was found in 12 patients, a score of 9 was found in 1, and a score of 8 was found in 2. CONCLUSIONS: Distraction arthroplasty of the trapeziometacarpal joint ensures good results in long-term follow-up, when performed in patients with stage I-II basal thumb osteoarthritis. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: The purpose of this study is to assess outcomes in flexor pollicis longus tendon repairs with 6-strand core sutures with and without circumferential sutures. METHODS: A 6-strand core suture technique with and without circumferential sutures was used. Thirty-three patients were summarized in the C group (circumferential group) and 16 patients in the NC group (non-circumferential group). After the surgery, the wrist was stabilized with a dorsal blocking splint and a controlled early active motion protocol was applied. At weeks 6, 13, and 26 data on demographics, type of injury, surgery, postoperative rehabilitation, complications such as re-rupture and the following outcome measurements were collected: range of motion and its recovery according to the Tang criteria, Kapandji score, thumb and hand strengths, Disabilities of the Arm, Shoulder and Hand score, and satisfaction. RESULTS: There were no significant differences in range of motion and strength between the 2 treatment groups. In both groups, the outcome measurements increased over time and they expressed similar satisfaction with the surgical treatment. In 4 patients of the C group tendon repair ruptured and in 1 patient of the NC group. CONCLUSIONS: Six-strand repair technique is an effective procedure to assure early active motion after flexor pollicis longus tendon injuries and good results can also be achieved by omitting the circumferential suture.

Background: Although there is no consensus regarding the best skin disinfection technique, whatever antiseptic solution is used, the "prep and drape" portion of most upper extremity procedures requires the presence of at least one operative room assistant or scrub nurse to elevate and hold the hand and forearm. Nonetheless, especially in a busy hand surgery practice and during fast procedures, an operative room assistant or scrub nurse are frequently not available leading to a reduced time efficiency between procedures. Purpose: This article describes an innovative easy-to-use and hands-free device that helps the surgeon during disinfection of the skin and the setup of the surgical field by keeping elevated the upper limb with respect for tissues. Methods: The development of the surgical arm holder starts from three easily available and washable thermoplastic splint sheets 40 × 60 cm with 2.5 cm thickness. The final device measures 40 × 25 × 15 cm and is placed underneath the proximal third of the humerus in order to keep the upper limb suspended at about 10-15 cm from the operating table. A retrospective analysis of the "surgical malpractice claims" and institutional non-conformities registered in the period 2011-2020 was conducted in our Hospital looking for bone or soft tissue complications related to the use of the device. Results: Three thousand one hundred eighty-seven surgical procedures were performed between 2011 and 2020 using this device. The retrospective analysis of all "surgical malpractice claims" showed no skin lesions, no neurological complications (such as neuroapraxia), no need for secondary bone procedures or interference with the draping process. Conclusion: Our device proved to be a low-cost, easy to use and alternative solution helping surgeons during the disinfection phase, improving hospital pre-operative flow and reducing the need for other staff members to be engaged in holding the upper limb in the operating room.
RESUMEN
Interphalangeal joints (IPJ) play a key role in hand function for performing activities of daily living and are frequently involved in complicated injuries resulting in significant functional limitations such as secondary arthritis and stiffness being the most challenging. In adult patients with more than 5 mm bone loss of the proximal articular surface who request a functional interphalangeal joint with minimal pain a vascularized joint transfer is a treatment choice. A unicondylar loss more than 5 mm wide in a 22-year-old carpenter is reported and illustrates our experience with a vascularized unicondylar transfer showing the advantages compared to the "classic" total joint transfer or distal interphalangeal (DIP) joint arthrodesis. By using this technique at the 12-month follow-up, we achieved no donor site complications, a good graft alignment, a good joint congruity, complete bone healing and a normal vascular patency with no signs of bone malunion or resorption of the graft.
RESUMEN
The best treatment for mallet fingers is still a matter of debate. Numerous splints with different designs to keep the distal interphalangeal (DIP) joint in extension have been described in literature. The outcomes of splint treatment are generally good with occasional reports of minor skin complications. Percutaneous Kirschner-wire pinning of the DIP joint for closed tendinous mallet finger represents a alternative treatment modality that reliably immobilises the joint and does not need much patient compliance or use of an external splint. We report a rare but devastating complication of percutaneous pinning of the DIP joint for closed tendinous mallet finger. Level of Evidence: Level V (Therapeutic).

Mechanically processed stromal vascular fraction (mSVF) is a promising source for regenerative purposes. To study the in vivo fate of the mSVF, we herein used a vascularized tissue engineering chamber that insulates the target mSVF from the surrounding environment. In contrast to previous models, we propose an arteriovenous (AV) shunt between saphenous vessels in rats without a venous graft. Mechanical SVF was processed from the fat pads of male Sprague Dawley rats, mixed with a fibrin hydrogel and implanted into an inguinal tissue engineering chamber. An arteriovenous shunt was established between saphenous artery and vein. On the contralateral side, an mSVF-fibrin hydrogel mix without vascular axis served as a non-vascularized control. After two and six weeks, rats were sacrificed for further analysis. Mechanical SVF showed significant numbers of mesenchymal stromal cells. Vascularized mSVF explants gained weight over time. Perilipin and CD31 expression were significantly higher in the mSVF explants after six weeks while no difference in DAPI positive cells, collagen deposition and FABP4 expression was observed. Morphologically, no differentiated adipocytes but a dense cell-rich tissue with perilipin-positive cells was found after six weeks. The phosphorylation of ERK1/2 was significantly enhanced after six weeks while Akt activation remained unaltered. Finally, mSVF explants stably expressed and released VEGF, bFGF and TGFb. Vascularized mSVF is able to proliferate and express adipocyte-specific markers. The AV shunt model is a valuable refinement of currently existing AV loop models in the rat which contributes to the fundamental 3R principles of animal research.
RESUMEN
The origin of fractures of the fifth metatarsus and Jones fracture is not clear. The goal of this study was to investigate the evidence of anatomical deformities such as metatarsus adductus, hindfoot varus, or pes cavus as risk factors for this pathology. A literature search of records related to the review question was performed screening PubMed/Medline, Embase and Cochrane library databases (last update: May 2020) according to PRISMA guidelines. A meta-analysis was performed using the mean difference of the assessed angles (in patients with the fractures vs controls) as outcome measure to summarize literature findings about metatarsus adductus angle (MAA) indicating forefoot adduction, calcaneal pitch angle (CP) indicating hindfoot cavus and varus deformity and Talo-1st metatarsus angle/Meary's angle (T1stMA) for varus alignment. Eight studies were included in the qualitative analysis (296 patients), 5 in the quantitative synthesis (132 patients). The pooled mean difference of MAA between fracture versus control group on a per patient-based analysis was 4.62 (95% CI 1.31-7.92). Statistical heterogeneity among studies was detected (I-Square: 76.1%), likely due to different patient groups and low number of studies. The pooled mean differences of CP and T1stMA among fracture group versus controls did not show statistical significance. Despite limited literature data, metatarsus adductus deformity seems to be correlated with higher risk of proximal metatarsal fractures and Jones fracture. A significant relationship between hindfoot varus or pes cavus and these fractures was not demonstrated. Further studies and trials are warranted to shed more lights on this topic.

BACKGROUND: Extensor tendon adhesions occurring after proximal phalangeal (P1) fractures are not uncommon. A previous report described the use of an adipofascial flap (AFF) to prevent adhesions after dorsal plating of the P1. The purpose of the study is to examine the results of open reduction and internal fixation with the use of an AFF (F group) and without (N group, that is, no flap used) in a larger group of patients. METHODS: A retrospective study involving a period of 11 years was conducted involving results of 21 unstable fractures of the P1 of the fingers in 18 patients. In all, 12 fingers were treated without any flap (N group) and 9 fingers were treated with the AFF (F group). For each patient, the total active motion (TAM) ratio, and the grip strength (Jamar) ratio were assessed, and adverse effects and the 10-point visual analogue scale (VAS) score were recorded. For statistical analysis, sample characteristics were described using mean ± standard deviation and median, and a Bayesian approach was used for inferential analysis. RESULTS: In the F group, the TAM ratio (84% ± 13% vs 65% ± 17%) was higher with a lower rate of adverse effects (OR: 0.067, 95% CI, 0.0035-0.58,) and a lower VAS score with evidence of the positive effect of the AFF. The Jamar ratio was similar in the 2 groups (F group 80% ± 25% vs N group 79% ± 19%) with no associated effect of the AFF on grip strength. CONCLUSIONS: The AFF is a reliable tool to reduce adhesions between plates and the extensor apparatus of the P1 and may be useful to improve finger function after plating of P1 fractures. TYPE OF STUDY/LOE: Therapeutic, Retrospective, Level IV.

Background Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques. Purpose The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness. Methods A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis. Key words included "open wrist arthrolysis," "arthroscopic wrist arthrolysis," "post-traumatic wrist stiffness," and "DRUJ arthrolysis." Data were extracted independently by a pair of reviewers. Results Overall, 637 studies were identified; 13 additional articles were found through previous publications (total 650 articles). A total of 612 records resulted after duplicates was removed. Fourteen studies were selected and only eight respected the inclusions criteria. One study focused on volar open arthrolysis and four studies on arthroscopic arthrolysis of the radiocarpal joint; two studies reported on open arthrolysis and two studies on arthroscopic DRUJ arthrolysis. Range of motion following open and arthroscopic wrist arthrolysis improved in all studies. Conclusion Both arthroscopic and open arthrolysis can lead to similar and satisfactory results in radiocarpal joint and DRUJ stiffness.. Level of Evidence This is a level 3a study.
RESUMEN
Pain In the Thumb and Other Fingers Abstract. As the population ages, symptoms of osteoarthritis in the hand are seen with increasing frequency. It can lead to substantial pain, physical disability and impair the patient's capacity to work in a population with an increasing retirement age. This article gives an overview about the most prevalent forms of osteoarthritis in the hand, its diagnosis and current treatment options, stressing that the multimodal form of therapy is the most effective.
