Abstract
Background:
Management of nail injuries tin often be a challenging experience, specially in presence of circuitous fingertips' injuries that include soft tissue loss and distal phalanx injury. Most studies found in the literature focus on individual injuries and describe methods to tackle those injuries, even so the fact that the nail, nailbed, distal phalanx, soft tissue and pare of the finger tip form a complex and often more than one element of this complex is injured. This retrospective study therefore focuses on the management of nail bed injuries as a part of the complex finger tip injury and outlines the surgical principles and techniques that were used in their management.
Materials and Methods:
Ii hundred and forty patients from a tertiary intendance center in dissimilar clinical settings where a wide multifariousness of cases involving the nail bed injuries were included in this study. Patients comprised of 192 (80%) males and 48 (xx%) females with the boilerplate male age of 37.iii years (range ane-66 years) and average female age of 29 years (range 1-59 years). 210 patients had unmarried finger involment, 30 patients had two finger involvement (total fingers involved- 270). The middle finger was most commonly involved while the index finger was the second most commonest finger involved. In 198 (89.18%) patients local anaesthesia was used while in the rest: regional blocks [n = 10 (4.5%)] and full general anaesthesia [n = 14 (6.three%)] were used.
Results:
In this retrospective study, out of the full of two hundred and xl patients, 222 (92.5%) patients underwent surgery, while the residual 18 (7.five%) were treated conservatively. Two hundred and ten patients who underwent surgery had consummate healing over the course of treatment and followup, while four patients needed secondary interventional. 8 patients who had surgery were migrant workers were lost to follow up after surgery. Eight patients had postoperative complications that included infection, secondary necrosis, wound breakdown and not healing fractures.
Conclusion:
Accurate and timely diagnosis of nail bed injury and its meticulous repair is cardinal to the direction of any smash bed injury. However all boom bed injuries must be seen in the context of associated injuries of the finger tip circuitous, namely skin, soft tissue and distal phalanx injuries. Fixation of associated bony injury which closely underlines the nail bed and provides physical back up to the boom bed along with correction of soft tissue injuries in the form of flaps or grafts, compounded by the repair or replacement of nail plate in the kickoff 24 hours.

Introduction
The human nail is a unique cutaneous construction that develops around the 10thursday week of intrauterine life from the sole plate and ordinarily arises on the dorsal aspect of the tip of every finger or toe. While the nail provides stability and counter support to the soft tissue of the fingertip and functionally helps in lifting tiny objects and performing frail movements, esthetically a finger without a nail looks deformed and unnatural to the homo center notwithstanding the occasional pleasurable scratch that is often missed in the literature. Information technology is, therefore, imperative that every injury of the smash and nail bed complex is treated with the utmost care as the primary surgery is the best possible time to treat this injury. This paper reviews the causes and management of fingertip injuries with smash and smash bed injury and suggests possible strategies to reduce the incidence of such injuries along with a review of literature. Finger tip injuries can have multiple combinations of injuries involving the nail plate, boom bed, distal phalanx, and the soft tissue of the fingertip and therefore it is crucial that the management of all these injuries exist considered in toto, thereby resulting in better patient outcomes.
Materials and Methods
240 consecutive patients with boom bed injuries referred to the plastic surgery section betwixt Apr 2011 and April 2016 were included in this study. The nature of the injury along with the pick of bachelor handling options was explained in item to all the patients, and they consented to undergo our direction choice preferred for their case. All patients were studied for the following parameters: age, sexual activity, cause of injury, detail of injury, finger involved, operative treatment, postoperative pain, postoperative complications, antibody coverage, and wound infection. All injuries were photographed, X-rayed, and details of the wound injuries were documented before treatment. On discharge, all injuries were treated and followed up until they healed completely or lost to followup. All patients were operated within the commencement 24 h except astringent crush injury cases where the vascularity was compromised and the patient was treated with venoactive drugs such as aspirin, pentoxifylline, and dipyridamole forth with maintaining warmth and hydration to improve the microcirculation. All wounds were washed thoroughly with povidone-iodine solution and saline at starting time contact with the patient to reduce the take a chance of infection and remove all the contaminants and debris. Further, all patients received intravenous broad-spectrum antibiotics on admission and these were converted to oral antibiotics on discharge of the patient and connected for 7 days, and if infection persisted, cultures were taken and antibiotics changed according to sensitivity studies. Patients with comorbidities such as diabetes were managed by a diabetic specialist, and strict blood glucose control was maintained by insulin therapy when needed. For demographic data the total number of patients (n = 240) were included but for the analysis of results, 232 patients were selected as 8 patients were lost to followup.
Results
Out of a total of 2 hundred and forty patients with nail bed injuries, 192 (80%) were males and 48 (20%) females. The average age of male person patients was 37.three years (range one-66 years) and an boilerplate historic period of female person patients was 29 years (range i-59 years). Of the 240 patients, 210 patients had single finger involment, 30 patients had two finger involvement (full fingers involved- 270) and eight patient had additional injuries. The most common finger involved was the heart finger, whereas the 2d well-nigh common finger involved was the index finger. The nigh common crusade of injury was industrial trauma [(n = 123) (51.25%)], followed by road traffic accidents [(north = 49) (20.41)], Kitchen food grinder injury (n = 38) (fifteen.83%) and door closure injuries [(n = thirty) (12.5%)]. All patients on admission were as protocol administered a combination of intravenous antibiotics namely ceftriaxone, amikacin and metronidazole as per standard dosages based on trunk weight for 48 hours and so shifted to oral cefuroxime medication for 7 days. New antibiotics were started merely on the ground of positive civilisation reports. In 222 (92.five%) patients, surgery was carried out while in 18 (seven.5%) patients, conservative handling was followed. Local anesthesia was used in 198 (89.18%) patients, whereas in the rest regional blocks [n = 10 (4.5%)] and general anesthesia [n = xiv (vi.3%)] were used. Table 1 shows a list of all surgical procedures done in our patients. 65 (27%) patients had fractures of the distal phalanx in i form or other and 44 of these had fixation of these fractures. While 210 patients of the total patients who underwent surgery had complete healing, 4 patients needed secondary surgery. Of this, 1 patient had a severe beat injury and farther necrosis was noticed postoperatively extending proximally in the smash bed and fingertip and therefore further debridement and wound repair was needed. In one patient, an infective granuloma appeared nether the distal edge of the blast plate which needed to be removed. In two patients, infection and breakup of wound occurred and secondary surgery was needed. In ii patients, the distal phalanx fracture (which was nowadays as the distal part of the distal phalanx and comminuted) failed to heal simply was left alone as it did not functionally interfere with the function and patients were reluctant to undergo further interference. V patients had wound infection[5/232, (2.xv%)] in their postoperative follow up catamenia and were successfully treated with antibiotics started as per the pus culture and sensitivity reports. Organisms isolated in the culture included staphylococcus aureus, klebseilla and pseudomonas. The average followup period was 1 years and 2 months (range 8-25 months). In 12 cases, the patients were unhappy with the quality of the new boom as it did non match the other finger nails though a new smash was formed on the repaired nail bed. The dominant hand was involved in153 (63.75%) patients while the nondominant hand was involved in 87 (36.25%) patients. All patients had some caste of postoperative pain which was treated with standard analgesics, and chronic pain (over 6 months) has non been reported past any of the patients. Full general anesthesia was preferred in pediatric cases and when other injuries in other body regions needing surgery were present or both hands were involved. Regional anesthesia was preferred when patients had multiple fingers interest. Eight patients who were migrants were immediately lost to followup.

Representative cases
Case 1
A 44-year-old male was involved in an industrial accident which resulted in the partial avulsion of proximal part of nail and nail bed plate with soft tissue injury and fracture of the distal phalanx [Figure 1a]. Under local anesthesia, a Kirschner wire fixation of the distal phalanx fracture was done followed by debridement and repair of the blast bed with 6-0 Vicryl. The nail plate was repositioned and sutured to provide external support [Effigy 1b and c]. Postoperatively, the wounds healed well, and adequate boom growth was seen on followup [Effigy 1d].

Case 2
A 23-year-erstwhile female person was referred with a food processor blade injury that accidently occurred while grinding food spices in a food processor. The injury resulted in the amputation of the tip of the correct eye finger with loss of about of the blast plate and smash bed along with partial loss of distal phalanx os and soft tissue of the fingertip [Figure 2a]. To reconstruct the tip and salve the blast bed remnant, a cross finger flap was done from the ring finger [Figure 2b]. The cantankerous finger flap was and then divided after 3 weeks, and a postoperative motion-picture show at nine months shows proficient soft tissue healing with new nail growth from the preserved remnant of the smash bed matrix [Figure 2c and d].

Discussion
The nail is an integument plant exclusively in primates while modifications of this are seen in other mammals. The sterile matrix provides an platonic bed to which the nail plate can exclusively adhere and any disruption will somewhen lead to nonadherence between the two.1 If the blast must grow, the germinal matrix needs to be preserved and if the nail must look normal, it must be well supported past the nail bed, the underlying bony distal phalanx, and the surrounding soft tissue. Injury to any of the structures that straight back up the boom and boom bed complex volition result in some abnormality, and therefore, it is essential that every fingertip injury is critically analyzed to nautical chart out the elements injured, and a programme is promulgated to repair the same in the most prudent manner. It is believed that in most fingertip injuries, the middle finger and the thumb are most frequently injured every bit the middle finger is the longest one, and the pollex is the most common finger used to grip something when the injury happens.2 Even so, in our serial, the almost frequently injured finger was the eye finger and the 2nd most mutual was the index finger.
Trauma remains the most common crusade of nail bed injury and deformity. In our study [Tabular array 2], the majority of the cases (n = 123; 51.25%) resulted from industrial accidents, and this could be explained by the fact that a large industrial belt with big and small-scale scale industries neighbors the infirmary. Post-obit common well-established safe measures at structure sites, industrial and other work sites would take helped to reduce these injuries. The second nigh common cause of boom bed injuries in this series was road traffic accidents (n = 49; 20.41%). The near common cause of injury in patients using two-wheeler vehicles was from the handle bar being hit by an oncoming vehicle. The mere presence of a simple handguard would take helped prevent this injury. Kitchen food grinder injury (n = 38; 15.83%) accounted for the third most common crusade of fingertip injury in our study. These injuries could be prevented by installing auto close off features in the grinder when the lid is opened. The last group of fingertip injury causes was from accidental closure of doors. This is a preventable injury which can exist avoided by simply attaching a "door closer:" a device that prevents the sudden and rapid closure of the door. Sporting injuries, iatrogenic, and self-inflicted injuries were conspicuous by their absenteeism in our series.

Causes of nail bed injuries
Since the nail bed is so intimately associated with the nail plate, distal phalanx and soft tissue of the finger tip, the surgical management of nail bed injuries must accost these other injuries as well. In contaminated wounds, immediate exploration and a thorough washout are essential as infection can be a serious consequence leading to even flexor sheath infection and distal amputation.3 All our patients underwent surgical repair of all injuries in the get-go 24 hours and were covered comprehensively with antibiotics. This acquired a low incidence of infection in this serial (2.15%). In treating subungual hematomas with more than than 50% surface area of the smash bed, we accept routinely used wherever necessary a x no. surgical stab bract to cut a small triangular hole in the nail plate to bleed the hematoma and give a saline washout under aseptic precautions, though the literature suggest the utilise of an 18 M needle, hot wire or drill.
In the presence of distal phalanx fractures, the possibility of concurrent significant smash bed injury is quite high and therefore removal of the nail plate, repair of the nail bed injury with fine half dozen-0 or seven-0 absorbable sutures, and replacing the nail plate every bit a protective embrace to the boom bed is advisable and this has been our standard mode of therapy in patients suspected to take nail plate injury. Strauss et al.iv used 2-octyl cyanoacrylate (Dermabond) to repair nail bed wounds and found that the repair was faster than suture repair and in addition provided similar cosmetic and functional results. However, in all our cases, nosotros accept done a suture repair. Wherever possible, we have replaced the blast to comprehend the injured nail bed as it has provided great support to the blast bed and helped in its healing. It also helps prevent synechiae between the eponychial fold and the nail bed. When the smash plate has been lost or damaged beyond use a silastic sheet or a bit of plastic cut to nail shape can be used. Ogunro5 reported that when the residuum boom bed is effectively covered to foreclose drying and maintain a local surround suited for tissue regeneration, normal nail growth may be obtained. Many surgeons use a effigy-of-eight sew together or its modifications to agree the nail plate in position.half-dozen Still, we accept always used unproblematic iv quadrant sutures to pivot the avulsed nail in position. Three of our patients had a significant expanse of nail bed loss. Still, none of them consented to taking a nail bed graft from the adjoining finger or the large toe which is the procedure that is recommended under the circumstances. This was likewise due to the fact that these patients were all workers and they were worried to let a normal finger or toe tip be subjected to a surgical process while they already had an injured finger. The vascular and lymphatic channels are well developed into the nail bed, and the presence of multiple anastomoses permits the use of the blast bed and smash matrix as flaps with acceptable results.vii In all these cases, the remnant nail bed was repaired along with other injuries, and healing resulted in meaning shortening of nail and deformity. In 4 patients who had minor loss of nail bed tissue, tiny local blast bed flaps were used to align and repair pocket-size defects in the blast bed. While the wounds may heal in 2–3 weeks, the nail plate will take around 3 months to abound completely. Splinting the finger for iii weeks helps the healing process and causes less pain to the patient, and this has been a regular feature in managing our fingertip injuries.
All soft tissue injuries of the fingertip must be meticulously repaired as they class a supportive framework for the boom bed. In the presence of exposed distal phalanx coupled with the loss of tissue, a flap encompass must be planned. A full of 58 flaps of various types were done in this series. Where the defect was key with exposure of distal phalanx, 5-y flaps were done. When the defect was either ulnar or radial wards, a Kutler flap was the preferred mode of flap comprehend. In some of the cases where the crush laceration injury prevented us from planning any such flaps, a small rotation advancement flap of the remnant soft tissue was done to cover the defect. When the defect was large, cross finger flaps were used, and when multiple fingers needed soft tissue cover, intestinal flaps were preferred. In few patients, these flaps were sometimes combined with small skin grafts where the flap was mainly used to embrace the exposed distal phalanx. While all attempts must exist made to restore the fingertip pulp with volar innervated flaps from the same finger for functional purposes, in cases where only soft tissue loss of the pulp without any bony injury or exposure is present along with the nail bed injury, skin grafting may be the procedure of pick. Sometimes, the blast and nail bed circuitous may be completely avulsed from the distal phalanx with only a distal zipper to the soft tissue. Here, again ane must access the viability of the avulsed tissue and debride and replace the unabridged complex back into its original position and suture it along the boom plate if available to enable maximum survival of the nail bed and subsequent nail growth. Small avulsed fragments can also be put back as composite-free grafts.
Fingertip injuries with nail bed injuries in children are often treated conservatively, and small wounds and lacerations may exist left to heal spontaneously. Roser and Gellman8 reported in their study in children that the results of simple nail trephination were equivalent to or superior to the removal of the boom and boom bed repair with significantly lower price when treating fingernail crush injuries with subungual hematoma. Small distal amputations of digits in infants take been known to survive every bit composite grafts, and this should be attempted after adequately cautioning the parents of the possible loss of the amputated role and need for reconstructive surgery.
The distal phalanx being closely related to the nail bed provides support and stability to the overlying nail bed from the volar side, and it is not surprising that distal phalanx fractures are found in about fifty% of blast bed injuries. In fingertip trounce injuries, distal phalangeal comminuted tuft fractures are quite mutual, but these practise not need any specific treatment as the soft tissue around it gives acceptable support forth with the nail bed repair. In majority of our patients, these tuft fractures were supported by smash bed repair, soft tissue repair, and external splinting. However, with fractures of the centre and proximal part of the distal phalanx too equally with displaced fractures, Kirschner wire fixation will exist needed to reach and maintain reduction of the fractures as were carried out in 44 of our patients. In all our cases wherever possible, the nail plate was put back and sutured in place – the boom plate acted equally a splint and also supported the distal phalanx fracture.
Even the nigh meticulous management of fingertip injuries may result in complications every bit predicting the eventual smash bed healing, and subsequent nail plate growth becomes difficult. In one of our patient who had a circuitous crush injury to the fingertip with bone and soft tissue loss, reconstruction with a v-y flap provided soft tissue cover to the exposed bone but resulted in a deformed nail growing over the tip of the finger in a curved mode (parrot beak deformity) that caused astringent hurting and interfered with the patient finger office. Eponychial injuries must exist meticulously repaired, but if there is a loss of eponychium which tin can lead to loss of nail smoothen and then replacing the eponychium as a composite graft from the toe has been suggested in the literature.ane Twenty 2 cases had eponychial lacerations which were repaired primarily in our series. A large number of our patients were transmission laborers and did non really bother nor complain about the loss of nail smoothen. In 1 of our cases, there was a nonadherence of the boom plate with the nail bed, and a granuloma appeared at the junction which was treated with antibiotics and curetting. Twelve of the patients had smash bed ridging possible from nail bed scarring on followup. Still, none of them wished whatever correction as it did not bother them functionally. 3 of our patients had bulbous fingertips on followup and all of these had severe crush injuries will comminute distal tuft fractures that were conservatively treated. Loss of bony distal phalanx support may sometimes need corrective bone grafting surgery after raising the nail bed complex equally a flap. Healed fingertip injuries are oft sensitive and sometimes painful, and therefore, rehabilitation of the fingertips must involve adapting the sensitive role to gradually increasing elapsing and frequency of stimulation as happened in three of our patients.9 In patients who had a total amputation proximal to the blast, reimplantation is a good technique if facilities are available.10 When the amputated function is crushed and unfit for reimplant and then doing a 5-y advancement flap and gratuitous grafting the nail bed has been reported.11 Abdominal flaps are commonly not preferred in the reconstruction of fingertip injuries as they are often bulky and insensate, but they were done in our cases when multiple fingers were involved or at that place was a significant loss of bone and soft tissue support for the blast bed and acceptable local flaps or cross finger flaps were not available.
Conclusion
Authentic and timely diagnosis of nail bed injury and its meticulous repair is central to the management of any nail bed injury. However all nail bed injuries must be seen in the context of associated injuries of the finger tip circuitous, namely skin, soft tissue and distal phalanx injuries. Fixation of associated bony injury which closely underlines the nail bed and provides physical support to the boom bed forth with correction of soft tissue injuries in the form of flaps or grafts, compounded by the repair or replacement of nail plate in the first 24 hours.
