J Hand Surg Am 2024; 49:607.e1-607.e7. [PMID: 36038426 DOI: 10.1016/j.jhsa.2022.06.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 05/14/2022] [Accepted: 06/29/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE This study aimed to evaluate the radiological and functional results of secondary thumb reconstruction via ectopic banking of bony phalanges from a nonreplantable amputated thumb. METHODS Thumb reconstruction was performed using the bony phalanges from a nonreplantable amputated thumb that were ectopically banked in a subcutaneous pocket. A wraparound flap was harvested from the ipsilateral great toe and wrapped around the bone graft. After surgery, the results were assessed in terms of infection, range of motion, bone union of the graft, and signs of osseous resorption of the reconstructed thumb. RESULTS Fifteen patients underwent secondary thumb reconstruction using this technique between January 2003 and October 2018. Ten patients were followed up for at least 6 months (6 months to 9 years) and were included in this study. All wraparound flap transfers were viable. No bone graft infection was observed. In the 6 cases in whom the interphalangeal joint was not fused, the interphalangeal joint motion ranged from 5° to 60° with an average of 35.0° ± 15.1°. The metacarpophalangeal joint motion ranged from 5° to 66°, with an average range of motion of 48.2° ± 23.6° for the cases in whom the joint was not fused. In 8 of the 10 patients, the time of bone ectopic banking was within 10 days. In these patients, bone union with no osseous atrophy was observed. In 2 patients whose phalanx was banked for more than a month, different degrees of bone resorption of the grafted phalanx were evident after transplantation, although no further treatment was required. CONCLUSIONS Bony phalanges from a nonreplantable amputated thumb can be ectopically banked and used for secondary reconstruction of the thumb. The duration of banking before thumb reconstruction should be no more than 2 weeks. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic V.

Abstract
BACKGROUND Complex injuries of the hand frequently result in loss of essential functional features. Common reconstructive procedures for soft tissue defects of the thumb or phalanges are locoregional flaps like Moberg-, Foucher-, Cross-Finger- or Littler flaps. Microneurovascular toe (joint-) transfers complete the arsenal of operative reconstructive procedures and allow for most detailed reconstructions. Our experiences with free toe transplants are reported and diversely discussed regarding contending procedures. METHODS From 2010 until 2019 14 patients who received emergency or elective partial or complete toe transfers were compared with a control group (n = 12) treated with contending reconstructive procedures. Aim of the reconstructions was to cover the defect with well-vascularized, sensate tissue, while preserving length and range of motion in a reliable manner. RESULTS The Kapandji score showed a significant difference (p- value = 0.04) with a score of 9.8 in comparison to control group (Kapandji index = 8.0). CONCLUSION In our heterogenic patient collective free toe transplants have proven to achieve comparable functional results for reconstruction of two and tripartite phalanxes as opposed to common local reconstructive procedures.

Abstract
BACKGROUND Toe transfer to hand is a viable option for patients, which can provide functionally useful digits. Harvesting of the second toe is still accepted as a demanding surgical procedure. The major questions before this transfer are the location and the dominance of the arterial anatomy of the second toe. The authors present the incidence of patients with a dominant plantar artery system and a description of a versatile technique that can be used for toe transfers in these patients. METHODS The study was designed retrospectively. Toe to hand transfers performed between 2010 and 2018 were reviewed. The patients with a dominant plantar arterial system were included in this study. The dorsalis pedis arterial graft technique described by the authors was used in all cases with a dominant plantar system. All of transfers were done by the senior author. All cases followed up at least one year post-operatively. The survival of the transferred finger was examined in the follow-ups. RESULTS Eleven toe to hand transplantation cases in nine traumatic patients were included in this series. The reason for the operation was trauma in all patients. Second toe transfer was performed in all of the cases. Plantar dominant arterial system was seen in 3 of the 9 patients. Dorsal arterial system was dominant in the remaining six patients. Dorsalis pedis arterial graft technique was used in these four cases. All of the toes survived, and reexploration was needed in 2 cases because of venous insufficiency. Mean follow-up time was 16.4 months. DISCUSSION This is the first study to recommend the use of dorsalis pedis as an arterial graft instead of vein grafts. This surgical method described will make these rarely performed transfers easier and affect the success rates positively.

Abstract
PURPOSE This study describes the results of the ring finger transfer technique for thumb reconstruction. METHODS Five fingers of 4 patients aged 23-57 years who presented to our clinic with an amputated thumb between 2017 and 2019 were included in this study. The results were assessed using Disabilities of Arm, Shoulder, Hand (DASH) scoring. Active range of motion, grip and pinch strengths, Kapandji scores, and static 2-point discrimination were measured. RESULTS The mean age of the patients (3 men, 1 woman) was 37 years (23-57 years). The level of amputation was the proximal phalanx in 3 digits and metacarpal in 2 digits. The average procedure time of was 89 ± 12 minutes. The average follow-up duration was 13 months (12-16 months). There was no total or partial digit necrosis in any patient. The mean preoperative shortened DASH score was 52.5 ± 6.7, and the mean postoperative score was 5.3 ± 6.5. The mean preoperative DASH Work Module score was 81.2 ± 18.8 and the mean postoperative score was 13.8 ± 7.5. Two-point discrimination was normal. CONCLUSIONS Transfer of the ring finger to reconstruct the amputated thumb is an alternative reconstruction method for patients who do not accept toe-to-thumb and pollicization techniques.

Abstract
Background Traumatic thumb amputation can have devastating effects on residual hand function. When replantation is not possible, thumb reconstruction is often performed in a delayed manner and may require multiple stages. Furthermore, reconstruction techniques often require microsurgical skills and equipment, which are not readily available at all institutions. This case series illustrates our technique for immediate osteoplastic thumb reconstruction following traumatic amputation. Methods This is a case series involving all patients who sustained unreplantable thumb amputations and underwent immediate osteoplastic thumb reconstruction with bone autograft and pedicled groin flap by the senior author from September 2016 through August 2018. Results Five patients underwent immediate osteoplastic thumb reconstruction during the study period. Total operative time for the initial osteoplastic reconstruction averaged 158 minutes (range 96-290 minutes). In addition to flap division surgery, patients underwent an average of 1.2 revision procedures (range 0-2), primarily for debulking and hardware removal. Patients achieved an average gain in length of 3.3 cm compared with the maximum anticipated length with revision amputation at the time of injury, and had stable clinical outcomes for a minimum of 12 months. Conclusions Osteoplastic thumb reconstruction is a useful technique for thumb reconstruction for select patients following traumatic thumb amputation. Advantages of this approach include shorter overall operative times and hospital length of stay, minimal donor site morbidity, and a straightforward, reproducible technique.

Abstract
Reconstructive microsurgery has been an essential aspect of orthopaedic surgery and extremity reconstruction since the introduction of the operating microscope in the mid-20th century. The reconstructive ladder ranges from simple healing by secondary intention to complex procedures such as free tissue transfer and vascularized composite allotransplantation. As orthopaedic surgery has evolved over the past 60 years, so too have the reconstructive microsurgical skills that are often needed to address common orthopaedic surgery problems. In this article, we will discuss a variety of complex orthopaedic surgery scenarios ranging from trauma to infection to tumor resection as well as the spectrum of microsurgical solutions that can aid in their management.

Abstract
Fingertip injuries occur commonly owing to trauma in everyday life. Performing amputation or stump revision for a fingertip injury can make it possible to quickly return to daily life, but causes functional and cosmetic problems. We believe that free flaps are the ideal way to minimize donor site morbidity and provide satisfactory reconstruction. Fingertips have different anatomic characteristics on the dorsum, volar aspect, and pulp, so it is necessary to select the appropriate free flap. Sometimes for larger defects, composite tissue transfer can be considered for reconstruction. This article discusses various free flap options for different fingertip defects.

Abstract
We describe here a platform for autonomous hand rehabilitation and telemonitoring of young patients. A toy embedding the electronics required to sense fingers pressure in different grasping modalities is the core element of this platform. The system has been realized following the user-centered design methodology taking into account stakeholder needs from start: clinicians require reliable measurements and the ability to get a picture remotely on rehabilitation progression; children have asked to interact with a pleasant and comfortable object that is easy to use, safe, and rewarding. These requirements are not antithetic, and considering both since the design phase has allowed the realization of a platform reliable to clinicians and keen to be used by young children.

Abstract
With the advent of the Industrial Revolution, traumatic injuries of the upper extremity increased exponentially. As a result, surgeons began to reevaluate amputation as the standard of care. Following the Second World War, local and regional pedicled flaps became common forms of traumatic upper extremity reconstruction. Today, microsurgery offers an alternative when options lower on the reconstructive ladder have been exhausted or will not produce a desirable result. In this article, the authors review the use of free tissue transfer for upper extremity reconstruction. Flaps are categorized as fasciocutaneous, muscle, and functional tissue transfers. The thin pliable nature of fasciocutaneous flaps makes them ideal for aesthetically sensitive areas, such as the hand. The radial forearm, lateral arm, scapula, parascapular, anterolateral thigh, and temporoparietal fascia flaps are highlighted in this article. Muscle flaps are utilized for their bulk and size; the latissimus dorsi flap serves as a "workhorse" free muscle flap for upper extremity reconstruction. Other muscle flaps include the rectus abdominis and serratus anterior. Lastly, functional tissue transfers are used to restore active range of motion or bony integrity to the upper extremity. The innervated gracilis can be utilized in the forearm to restore finger flexion or extension. Transfer of vascularized bone such as the fibula may be used to correct large defects of the radius or ulna. Finally, replacement of "like with like" is embodied in toe-to-thumb transfers for reconstruction of digital amputations.

Abstract
Supplemental Digital Content is available in the text. Background: Amniotic Band Syndrome is a clinical constellation of congenital anomalies characterized by constricting rings, tissue synechiae and amputation of body parts distal to the constriction bands. Involvement of the hand with loss of multiple digits not only leads to devastating deformities but also loss of functionality. Methods: In this series, utilizing microvascular transfer of the second toe from both feet, along with local tissue reconfiguration, a tetra-digital hand with simile of normal cascade was reconstructed. A consecutive series of eight children with Amniotic Band Syndrome, younger than two years in age operated on by single surgeon over a twenty five year interval was reviewed. Results: There was no flap loss. The hands were sensate with effective simple prehensile function. Conclusion: Application of Microvascular toe-to-hand transfer for well selected, albeit severe hand deformity in Amniotic Band Syndrome is a valid surgical concept.

Abstract
Objectives. We evaluated the results of digital lengthening by distraction and second-stage bone graft. Methods. We treated finger deficiency of 201 digits in 104 patients (68 males, 36 females) by digital distraction and second-stage bone graft. The distraction was performed with a rate of 1 mm/day (for the first ten days) and 0.5 mm/day followed by using a self-designed bilateral tubal-helical external fixator. The mean follow-up period was 42 months (range 6 to 60 months). Results. The mean lengthening was 29.2 mm (range 25 to 40 mm) and 18.7 mm (range 12 to 32 mm) for metacarpal bones and phalanges, respectively. The mean elongation rate was 174.4% (range 145% to 202%) and 184.8% (range 115% to 283%) for metacarpal bones and phalanges, respectively. The static two-point discriminations and SpO2 showed no significant differences before and after distraction. Four complications were observed (two skin ruptures and two phalangeal splitting). No pin tract infection or tendon rupture showed. Digital lengthening improved functions of the hand. Conclusion. Digital distraction and second-stage bone graft is an effective method to compensate disabilities caused by lack of finger length. It could be an alternative plan for patients with thumb deficiency instead of toe-to-thumb transplant and patients with finger deficiency instead of ray resection.

Abstract
When used to reconstruct a finger proximal interphalangeal joint, a free toe interphalangeal joint, without modification, cannot meet the motion demands of the finger to allow palm touchdown. This limitation is the direct result of the toe interphalangeal joint having an intrinsic arc of motion that delivers less flexion than that of a normal functioning finger proximal interphalangeal joint. By modifying the inset of the transferred joint to an extra-anatomical more proximal position, this limitation can be overcome. With a mathematical justification highlighted by a clinical illustration, we demonstrate the feasibility and utility of this "proximalization" technique.

Abstract
The thumb plays an integral role in hand function. Traumatic amputation results in significant morbidity. With loss of the thumb, up to a 40% reduction in hand function may result. Thumb replantation must be attempted when possible. The goals of thumb reconstruction are to replicate normal function as closely as possible, minimize donor site morbidity, and expedite recovery. In the setting of a mutilated hand, the status of the remaining digits must be carefully assessed. Toe transfers, osteoplastic thumb reconstruction, and pollicization are commonly used. This article summarizes the indications and technical considerations in addressing the deficiencies after thumb amputation.

Abstract
INTRODUCTION Amputation of the thumb presents a serious insult to the hand and diminished quality of life for a patient physically, vocationally, and possibly psychologically. The aim of this study was to define the geometry of the thumb metacarpal in order to help create a standardized set of transcutaneous osseointegrated prostheses to treat patients who have suffered amputation of the thumb at the level of the metacarpophalangeal joint. MATERIALS AND METHODS A total of 80 metacarpals from 46 cadavers were studied. All soft tissues were removed and the thumb metacarpals were imaged using computed tomography. Three-dimensional models were constructed using images from the coronal, sagittal, and axial planes. Using HyperMesh™ CAD software, the bones were analyzed for overall length, radius of curvature, medullary canal diameter, cortical thickness, and distance to the isthmus, defined as the narrowest portion of the intramedullary canal. RESULTS The average length of the first metacarpal was 47.6 mm (±3.3 mm, 39.2-56.9 mm). The average radius of curvature was 55.5 mm (±10.7 mm, 33-78.9 mm). Inner bone diameter, measured in two axes, was 10.5 mm (±1.3 mm, 5.4-18.7 mm) for the major axis and 7.7 mm (±0.9 mm, 4.3-17.8 mm) for the minor axis. The average cortical thickness was 1.4 mm (±0.3 mm, 0.7-3.1 mm). The distance to the center of the isthmus from the distal end had an average length of 21.3 mm (±1.9 mm, 17-25 mm). CONCLUSIONS Using these findings a standardized set of intramedullary stems can be developed as a base for a transcutaneous osseointegrated prosthesis, helping to create a reliable method for treating patients with amputated thumbs.

Abstract
Amputation of the thumb causes not only loss of significant functional use of the hand but also psychological and social problems. The procedures of toe-to-thumb transfer, pollicization, or metacarpal extension are recognized and well-documented options in thumb reconstruction. Although these techniques have been successfully applied, they have some disadvantages. This study aims to test the feasibility of the fifth finger for thumb reconstruction. The fifth finger was released following exploration of the digital artery, vein, nerve, and flexor and extensor tendons, including the flexor retinaculum. The digital vein and the extensor tendon of the fifth finger were separated at the level of the metacarpophalangeal joint. The proximal phalanx of the fifth finger was cut smoothly at the level of the metacarpophalangeal joint with a saw. The deep flexor tendons, digital arteries, and nerves were preserved. The proximal phalanx of the released fifth finger was fixed to the first metacarpal bone. The digital vein of the first finger was anastomosed to the digital vein of the fifth finger by microsurgery. Angiography was done after the transfer. Exploration till the flexor retinaculum enabled thumb transfer without any restriction of movement in all 10 cadaver fingers. The average total surgical time was 135 ± 12 minutes. Flow from both radial and ulnar arteries was demonstrated in the transferred fifth finger by angiography. The technique appears to be feasible for thumb reconstruction by preserving digital arteries and nerves in a relatively short time, but further important aspects have to be assessed in further clinical studies.

Abstract
BACKGROUND Posttraumatic loss of the thumb is devastating. Toe-to-hand transfer is considered the criterion standard of reconstruction but is associated with donor-site issues. The twisted-toe technique uses parts from the great toe and the second toe, which allows for almost anatomical restoration of the donor foot. The authors present their experience and technical modifications of this method. METHODS Between January of 2003 and November of 2011, 18 patients suffering from loss of thumb because of a variety of indications were treated with the authors' modification of the twisted-toe technique. The neothumb was constructed with a partial onychocutaneous flap from the great toe and an osseotendinous flap from the second toe. RESULTS Of 18 transplanted twisted-toe flaps, 17 survived completely (5.6 percent flap loss rate). Similarity of the reconstructed thumb compared with the healthy side was very acceptable in all cases. All patients in whom the procedure was successful were able to use the neothumb in daily life without constraints. Reconstruction of the donor site yielded very acceptable outcomes with a distinct reduction in morbidity and disfigurement compared with conventional toe harvest. CONCLUSIONS The modified twisted-toe technique is the authors' preferred choice of thumb reconstruction. It allows the reconstructive surgeon to construct a very natural-appearing neothumb with good stability and grip force. In addition, it eliminates many of the donor-site problems associated with pure great toe harvest, by recreating a "neo-great toe" at the donor foot. Although the procedure is more complicated and time-consuming compared with single toe harvest, the authors firmly believe that this extra effort takes thumb reconstruction to a next level. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Toe-to-hand transfer is indicated for many types of congenital and traumatic thumb absences. This review will highlight the applications of toe-to-hand transfer and their functional, aesthetic, and psychosocial outcomes. Despite its technical complexity, toe to hand reconstruction techniques can provide an elegant option to restore function for patients with difficult hand disabilities.

Abstract
Since the advent of the operating microscope by Julius Jacobson in 1960, reconstructive microsurgery has become an integral part of extremity reconstruction and orthopaedics. During World War I, with the influx of severe extremity trauma Harold Gillies introduced the concept of the reconstructive ladder for wound closure. The concept of the reconstructive ladder goes from simple to complex means of attaining wound closure. Over the last half century microsurgery has continued to evolve and progress. We now have a microsurgical reconstructive ladder. The microsurgical reconstruction ladder is based upon the early work on revascularization and replantation extending through the procedures that are described in this article.
