From Simple to Complex: Preserving and Reconstructing the Traumatized Thumb.

Traumatic thumb injuries significantly affect overall hand function and may result in considerable disability. Reconstructing the traumatized thumb requires a detailed preoperative assessment of the defect and evaluation of the patient's social history and medical comorbidities. Reconstructive techniques can be stratified by the level of thumb injury. The goals of thumb reconstruction are to restore length, stability, mobility, and sensibility. This article reviews reconstructive principles and operative techniques for reconstructing the traumatized thumb.

Pollicization and Pediatric Thumb Reconstruction.

Functional impairment, absence, or traumatic loss of the thumb is associated with considerable morbidity. A fully functioning thumb is estimated to account for 40% of hand function. An array of options exists for thumb reconstruction, and the intervention selected must be tailored to each individual patient. Pollicization is a powerful and elegant operation that can dramatically improve function for many patients. However, the surgeon and patient must be keenly aware that pollicization does not construct a "normal" thumb. Herein, we present a stepwise approach to treatment, including surgical nuances, alternatives to pollicization, complications, and outcomes.

Thumb dorsal skin composite tissue replantation: A case report.

The primary goal is to preserve thumb integrity and functionality to the greatest extent possible, even in cases involving very small amputated parts. In this article, we present a case in whom the seemingly non-replantable dorsal skin-nail composite tissue of the thumb could be successfully replanted with a single artery anastomosis. No additional procedures were required, and complete recovery was achieved. In conclusion, given the unique vascular structure of the thumb, all amputated parts should be carefully evaluated for replantation. Replanting a partially amputated finger yields superior functional and cosmetic outcomes compared to any reconstructive method.

The treatment, outcomes and management of hand, wrist, finger, and thumb injuries in the professional/amateur contact sport athletes: A scoping review.

INTRODUCTION: Amateur and professional participation in sport and physical activity worldwide is increasing in popularity, which in turn is increasing the volume and types of injuries sustained by athletes. Ensuring these injuries are treated appropriately and efficiently is paramount for athletes' recovery and return to sport in a timely and safe manner. METHODS: A scoping review to map the evidence regarding the treatment, outcomes and management of hand, wrist, finger, and thumb injuries in the professional/amateur athlete from contact sports. A search of seven electronic databases; SPORTdiscus, CINAHL, Medline, Scopus, Web of Science, Embase and Cochrane Library and grey literature was conducted in January 2024. The reporting of the review is in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews Checklist. Inductive content analysis was used to examine the data and the Critical Appraisal Skills Programme was used to appraise the quality of the included studies. RESULTS: Eight papers met the inclusion criteria and three themes emerged addressing the return to play/sport, surgical and conservative treatment and the most common/reoccurring injuries sustained from contact sports. CONCLUSION: Managing hand, wrist, finger, and thumb injuries in athletes requires a varied approach depending on the type of injury, treatment options, and external pressures. While conservative treatment is common and effective, surgical intervention may be necessary in certain cases to improve recovery and facilitate a faster return to sport. Preventive measures in high-risk sports settings could help reduce the incidence of these injuries.

Outcomes of Arthrodesis of the Metacarpophalangeal Joint of the Thumb for Sequelae of Collateral Ligament Injuries: A Series of 18 Cases with 6-Year Follow-Up.

Background: Untreated or insufficiently treated collateral ligament injuries of the thumb metacarpophalangeal (MP) joint can lead to instability or even osteoarthritis. Arthrodesis is one of the treatment options available for the treatment of the sequelae of collateral ligament injuries. The objective of our study was to evaluate the radiological, clinical and functional outcomes of MP joint arthrodesis performed for sequelae of collateral ligament injuries. Methods: We conducted a retrospective, single-centre study and reviewed the files of patients who had a thumb MP joint arthrodesis following a collateral ligament injury between 2011 and 2019. We collected patient's demographic data and the results of the radiological and clinical examinations. Results: Eighteen patients were included in the study. The average age was of 53.6 years and the time between injury to arthrodesis averaged 7 years. Four patients (22%) had nonunion. In the remaining 14 patients with solid union at an average of 72 months follow-up, the visual analogue pain score at rest was 0.14, the thumb opposition was 82%, grip strength 85%, tip pinch 92% and key pinch 79% of the contralateral side. Conclusions: The clinical and functional results of patients with a successful arthrodesis are satisfactory with restoration of good grip and pinch strength. Despite a lack of thumb MP joint flexion, stability allowed force transmission and may be preferred for manual workers. Level of Evidence: Level IV (Therapeutic).

Volar dislocation of the metacarpophalangeal joint of the thumb: open reduction and repair of the ulnar collateral ligament. A case report.

INTRODUCTION: metacarpophalangeal dislocations of the thumb are not very frequent injuries, it is necessary to know the anatomy of the region to know possible causes of interposition that prevent a closed reduction of this pathology. CASE PRESENTATION: we present the case of a 75-year-old woman with a post-traumatic metacarpophalangeal dislocation of the thumb that required open reduction and surgical repair. In this procedure, we performed reduction of the dislocation, mobilization of the interposed structures, repair of the capsule and reinsertion of the ulnar collateral ligament. The early mobilization protocol helped to obtain very good results. CONCLUSION: it is imperative to consider possible associated injuries during the acute phase to achieve optimal short, medium, and long-term outcomes for our patients. A comprehensive and proactive approach to diagnosis and treatment is vital in effectively addressing this pathology and minimizing its potential sequelae.

INTRODUCCIÓN: las luxaciones metacarpofalángicas del pulgar no son lesiones muy frecuentes, es necesario conocer la anatomía de la región para conocer posibles causas de interposición que impidan una reducción cerrada de esta patología. PRESENTACIÓN DEL CASO: presentamos el caso de una mujer de 75 años con luxación metacarpofalángica postraumática del pulgar que requirió reducción abierta y reparación quirúrgica. En este procedimiento realizamos reducción de la luxación, movilización de las estructuras interpuestas, reparación de la cápsula y reinserción del ligamento colateral cubital. El protocolo de movilización temprana ayudó a obtener muy buenos resultados. CONCLUSIÓN: es imperativo considerar posibles lesiones asociadas durante la fase aguda para lograr resultados óptimos a corto, mediano y largo plazo para nuestros pacientes. Un enfoque integral y proactivo del diagnóstico y tratamiento es vital para abordar eficazmente esta patología y minimizar sus posibles secuelas.

Novel figure-of-eight reconstruction with free tendon graft for unrepairable collateral ligament of the thumb metacarpophalangeal joint.

OBJECTIVES: This study aimed to report surgical technique and clinical outcomes for a novel figure-of-eight collateral ligament reconstruction technique using palmaris longus autograft for chronic irreparable collateral ligament injury of the thumb metacarpophalangeal joint. MATERIAL AND METHODS: The Jobe elbow collateral ligament reconstruction method was adapted for thumb metacarpophalangeal joint collateral ligament reconstruction. Sixteen reconstructions (7 ulnar collateral ligament, 9 radial collateral ligament) using palmaris longus autograft were reviewed retrospectively. Surgery was performed at a mean 12 months post-injury. All 16 patients were followed up for more than 1 year. Metacarpophalangeal joint radial and ulnar deviation, metacarpophalangeal and interphalangeal joint range of motion, key pinch and grip strength, Glickel functional grade and QuickDASH score were evaluated. RESULTS: Preoperative radial or ulnar deviation improved from 19.3° to 5.3° postoperatively. Metacarpophalangeal range of motion improved from 31.5° to 46.6°, and interphalangeal range of motion from 48.4° to 65.6°. Preoperative key pinch and grip strength were respectively 49% and 81% of contralateral values and improved to 82% and 87%. On Glickel grade, 9 cases were excellent and 7 good. CONCLUSION: The novel Jobe-like figure-of-eight reconstruction technique using palmaris longus graft was useful for reconstructing irreparable thumb metacarpophalangeal joint instability without an incision on the opposite side or an additional implant. LEVEL OF EVIDENCE: Therapeutic study, level IV.
