[Effectiveness comparison of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet finger].

Objective: To compare the effectiveness of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet fingers. Methods: The clinical data of 68 patients with bony mallet finger who admitted between May 2019 and June 2022 were retrospectively analyzed. Among them, 33 cases were in the open group (treated with open reduction and hook plate fixation) and 35 cases were in the closed group (treated with closed indirect reduction and dorsal extension blocking Kirschner wire fixation). There was no significant difference between the two groups in terms of gender, age, the affected side, the affected finger, cause of injury, time from injury to operation, and Wehbé-Schneider classification ( P>0.05). The operation time, intraoperative fluoroscopy frequency, fracture healing time, time of returning to work, and postoperative complications were recorded and compared between the two groups. At 12 months after operation, visual analogue scale (VAS) score was used to assess the pain of the injured finger, active flexion range of motion and extension deficit of the distal interphalangeal joint (DIP) were measured by goniometer, and the effectiveness was assessed by Crawford criteria. Results: All patients in the two groups were followed up 12-26 months, with an average of 15 months. There was no significant difference in the follow-up time between the closed group and the open group ( P>0.05). The operation time in the closed group was shorter than that in the open group, and the intraoperative fluoroscopy times, the fracture healing time, and the time of returning to work in the closed group were more than those in the open group, and the differences were significant ( P<0.05). In the closed group, there were 5 cases of pinning tract infection and 3 cases of small area pressure ulcer skin necrosis on the dorsal side of the finger, which were cured after intensive nursing and dressing change. Local nail depression deformity occurred in 7 cases in the open group, and the deformity disappeared after removal of plate. The incisions of the other patients healed uneventfully without complications such as infection, skin necrosis, exposure of the internal fixation, or nail deformity. There was no significant difference in the incidence of skin necrosis between the two groups ( P>0.05), but the differences in the incidence of infection and nail deformity between the two groups were significant ( P<0.05). There was no significant difference in VAS score, DIP active flexion range of motion, DIP extension deficiency, or Crawford criteria evaluation between the two groups at 12 months after operation ( P>0.05). At last follow-up, there was no DIP osteoarthritis and joint degeneration in both groups. Conclusion: Open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation have their own advantages and disadvantages, but both of them have good results in the treatment of bony mallet fingers. Open reduction and hook plate fixation is recommended for young patients with bony mallet fingers who are eager to return to work.

Ring-Embedded Finger Over Proximal Interphalangeal Joint with Preserved Neurovascularization: A Case Report and Literature Review.

CASE: We present a unique case of a 45-year-old man with his right middle finger embedded with rings. Limited finger flexion was noted because of flexor tendon injury caused by the dorsal migration of the embedded ring through joint. The rings were removed under anesthesia, resulting in the resolution of swelling and recover of osseous structure. Follow-up examinations revealed no residual edema or numbness, indicating preserved neurovascularization, despite the dorsal migration of the ring. CONCLUSION: Our unique case reveals continuous finger ring migration without compromising neurovascular bundles, with review of 30 cases emphasizing the importance of psychiatric consultation. Timely intervention yielded nearly half of patients achieving full recovery.

An extremely rare case of absent extensor digitorum communis of the right index finger.

The hand is a unique structure in human body performing complex activities of daily life making it prone to injuries. While operating on zone VI extensor tendon injury, a surprising entity was observed. The extensor digitorum to the right index finger was absent. This is an extremely rare entity in the literature. Also, all previous studies on the extensor digitorum are cadaveric. Our findings are first of its kind intraoperative, incidental, and confirmed on MRI. Thus, it becomes a case report of special worth mentioning in literature.

[Finger injuries in athletes]. / Lésions des doigts chez le sportif.

Hand injuries in sportives are becoming increasingly common, accounting for approximately 25% of all sports-related injuries. The recent growing popularity for sports such as climbing, which even became an Olympic discipline in 2022, is increasing hand and finger injuries in the active population. Some sports are more prone to typical hand and finger injuries. These injuries need to be treated quickly and correctly, to enable the athlete to receive optimal treatment followed by appropriate rehabilitation, in order to return to his or her sport in the best possible conditions. We have chosen to highlight five of these specific pathologies to help general practitioners and sports physicians to make an accurate diagnosis and manage or refer these injuries as best as possible.

Les pathologies de la main chez le sportif sont de plus en plus courantes, représentant 25 % de toutes les blessures sportives. L'engouement récent pour des sports tels que l'escalade, devenue même discipline olympique depuis 2022, accroît les blessures à la main et aux doigts dans la population active. Certains sports exposent davantage à des blessures typiques de la main et des doigts. La prise en charge de ces lésions doit se faire rapidement et correctement afin de permettre à l'athlète un traitement optimal suivi d'une rééducation adaptée et un retour au sport dans les meilleures conditions. Nous avons choisi de mettre en lumière cinq de ces pathologies spécifiques afin d'aider les médecins généralistes et du sport à poser un diagnostic précis et prendre en charge ou orienter correctement ces blessures.

[An unusual case: fracture of the handle of the malleus due to finger manipulation]. / Ein ungewöhnlicher Fall: Fraktur des Hammergriffs durch Fingermanipulation.

An isolated fracture of the handle of the malleus is a rare entity in otorhinolaryngology and manifests clinically as acute-onset unilateral hearing loss. Several factors may cause this injury, including acute barotraumatic pressure changes or traumatic events. Various therapeutic approaches such as tympanoplasty, autologous graft, or application of bone cement are discussed. We report the case of a 46-year-old female patient who developed acute hearing loss in her left ear after finger manipulation. Clinical evaluation revealed axial displacement of the handle of the malleus and audiometry indicated conductive hearing loss. After otoscopy, audiometry, and computed tomography, tympanoscopy was indicated due to suspicion of ossicular chain disruption. Intraoperatively, an isolated fracture of the handle of malleus was found, which was treated with glass ionomer cement. Following postoperative examination, there was progressive improvement in the acoustic transmission component, such that a normal hearing threshold was observed 4 months postoperatively. This case report underlines the importance of precise diagnosis and individualized treatment for rare middle ear injuries.

Acute fingertip and nail injuries in the hand.

A correct diagnosis and treatment of fingertip- and nail injuries, commonly seen in the emergency room, is crucial. Insufficient treatment can result in long-term complications, including finger dysfunction and dysaesthesia, nail deformity, infection, or pain. These remaining problems may induce severe impairment of the quality of life of the patient. This review summarises the diagnosis and treatment.

Pins and Rubber Band Traction System Combined with Internal Fixation for Intra-articular Fractures of the Proximal Interphalangeal Joints.

Background: Intra-articular fractures of the proximal interphalangeal joint (PIPJ) can result in poor outcomes if inadequately treated. Dynamic external fixation and internal fixation with plates and/or screws are two treatment options. The role of combining these two methods is unclear. The aim of this study is to determine the outcomes of patients with intra-articular fractures of the PIPJ treated with a combination of dynamic external fixation with a plate and/or screws. Methods: A retrospective review was conducted on 18 consecutive cases of intra-articular fractures of the PIPJ treated with pins and rubber band traction system (PRTS) combined with dorsal internal fixation with plates and/or screws. The patients' average age was 51 years (range: 20-81 years). The fracture patterns were volar-type (n = 2), dorsal-type (n = 4) and pilon-type (n = 12). Data with regard to time to surgery, interphalangeal joint range of motion, grip strength, VAS for pain, Quick DASH score, complications, duration of follow-up and return to work were collected. Results: The levels of articular involvement were stable (n = 1), tenuous (n = 5) and unstable (n = 12). The average time to surgery was 9 days, and the average follow-up period was 15 months. The fracture was fixed with a dorsal plate and screws in 10 patients and with only screws in eight patients. All patients had PRTS. All patients returned to their original occupation and the fractures united in good alignment. The average grip strength was 86% of that of the unaffected side. The average active PIPJ motion was 85° (range: 50°-106°), and the average active distal interphalangeal joint (DIPJ) motion was 48° (range: 10°-90°). Conclusions: Our results show that a combination of PRTS and open reduction and fixation with plate and/or screws achieved a good range of motion and articular reduction. Level of Evidence: Level IV (Therapeutic).

The effect of injury area on the success of treatment in digital nerve injury.

INTRODUCTION: The main objective of the current study is to investigate variations in postoperative outcomes that follow digital nerve repair in Zone 1 and Zone 2, respectively. We hope that by carrying out this investigation, we will be able to identify which zone has better sensation recovery and patient-reported outcomes, allowing us to identify the best way of conducting surgery for specific types of injuries. MATERIALS AND METHODS: A retrospective cohort study was conducted in patients with digital nerve injuries treated in a designated hand surgery clinic between January 2021 and December 2023. The study was guided by ethical consideration, where all participants gave their informed consent. Surgical interventions involved primary repair, autograft/allograft nerve grafting, nonsurgical approaches, as well as conduit repair in which results were determined using objective measures and patient feedback. RESULTS: Direct repair emerged superior among injuries of Zone 1 and Zone 2 with high success rates and good patient-reported outcomes. In general, injuries in Zone 1 had better sensory recovery than injuries in Zone 2 and this was associated with higher levels of satisfaction. Comparisons using statistical methods confirmed that direct repair outperformed other modalities. CONCLUSION: More importantly, the comparison of this study shows that repairs in Zone 1 are more successful than those in Zone 2 revealing direct repair as a superior method for digital nerve injuries. The difference is crucial because it suggests that surgical efficiency may depend on where the injury is. This means that direct repair should be given priority over the two zones, although surgeons will need to watch out for challenges related to Zone 2 injuries and adjust their strategies accordingly to obtain the best patient outcomes possible.

Repair of distal finger soft-tissue defects with free fibular great toe neurovascular flaps.

BACKGROUND: This work aimed to investigate the change in fingerprint depth and the recovery rule of fingerprint biological recognition function after repairing finger abdominal defects and rebuilding fingerprint with a free flap. METHOD: From April 2018 to March 2023, we collected a total of 43 cases of repairing finger pulp defects using the free flap of the fibular side of the great toe with the digital nerve. After surgery, irregular follow-up visits were conducted to observe fingerprint clarity, perform the ninhydrin test or detect visible sweating with the naked eye. We recorded fingerprint clarity, nail shape, two-point discrimination, cold perception, warm perception and fingerprint recognition using smartphones. The reconstruction process of the repaired finger was recorded to understand the changes in various observation indicators and their relationship with the depth of the fingerprint. The correlation between fingerprint depth and neural repair was determined, and the process of fingerprint biological recognition function repair was elucidated. RESULT: All flaps survived, and we observed various manifestations in different stages of nerve recovery. The reconstructed fingerprint had a clear fuzzy process, and the depth changes of the fingerprint were consistent with the changes in the biological recognition function curve. CONCLUSION: The free flap with the digital nerve is used to repair finger pulp defects. The reconstructed fingerprint has a biological recognition function, and the depth of the fingerprint is correlated with the process of nerve repair. The fingerprint morphology has a dynamic recovery process, and it can reach a stable state after 6-8 months.

Monodigital Double Cross-Finger Flaps-A Novel Approach for Coverage of Large Volar Defects.

INTRODUCTION: A single cross-finger flap can only address digital defects of a limited size, and larger defects often require distant flaps such as abdominal or groin flaps that are cumbersome to perform and sometimes bulky. Two cross-finger flaps harvested from the same donor digit could offer a simple and effective solution for many such defects. In this study, we describe the technique of monodigital double cross-finger flaps and its clinical applicability, with evaluation of donor and recipient site morbidity. METHODS AND MATERIALS: A total of 10 subjects with large volar defects were included in the study. The demographic data, etiology, defect size, flap donor, and recipient sites were tabulated prior to surgery. Each subject was assessed for postoperative complications at the donor and recipient site and followed up for 6-12 months to document any flap or donor site morbidities. RESULTS: The subjects included 9 males and 1 female subjects, with an average age of 35.6 years (21-67 years). Most patients had posttraumatic defects, with 3 cases of full thickness burns and one with postsurgical tissue necrosis. All defects were volar, with 4 on the little finger, 3, 2, and 1 in the ring, index and middle fingers, respectively. No major postoperative complications were noted in any case. All flaps survived well with good contour, and donor fingers achieved near-normal range of flexion with only minimal restriction (10-15°) at the distal interphalangeal joint that did not result in any overall functional disability. CONCLUSIONS: Monodigital double cross-finger flap technique offers a simple and effective solution for reconstruction of large digital defects that are not amenable for closure by a classical cross-finger flap, and is a good alternative for other procedures, providing supple soft tissue coverage and no significant morbidity at the donor digit provided that there is preservation of a small skin bridge across the proximal interphalangeal joint.

Amputated Digit Replantations: Critical Digit Ischemia Timing, Temperature, and Other Predictors of Survival.

INTRODUCTION: A common consideration for replantation success is the ischemia time following injury and the preservation temperature. A classic principle within the hand surgery community describes 12 hours of warm ischemia and 24 hours of cold ischemia as the upper limits for digit replantation; however, these limits are largely anecdotal and based on older studies. We aimed to compare survival data from the large body of literature to aid surgeons and all those involved in the replantation process in hopes of optimizing success rates. METHODS: The PubMed database was queried on April 4th, 2023, for articles that included data on digit replantation survival in terms of temperature of preservation and ischemia time. All primary outcomes were analyzed with the Mantel-Haenszel method within a random effects model. Secondary outcomes were pooled and analyzed using the chi-square statistic. Statistical analysis and forest plot generation were completed with RevMan 5.4 software with odds ratios calculated within a 95% confidence interval. RESULTS: Our meta-analysis identified that digits preserved in cold ischemia for over 12 hours had significantly higher odds of replantation success than the amputated digits replanted with 0-12 hours of warm ischemia time ( P ≤ 0.05). The odds of survival in the early (0-6 hours) replantation group were around 40% greater than the later (6-12 hours) replantation group ( P ≤ 0.05). Secondary outcomes that were associated with higher survival rates included a clean-cut amputation, increased venous and arterial anastomosis, a repair that did not require a vein graft, and replants performed in nonsmokers ( P ≤ 0.05). DISCUSSION: Overall, these findings suggest that when predicting digit replantation success, time is of the essence when the digit has yet to be preserved in a cold environment. This benefit, however, is almost completely diminished when the amputated digit is appropriately maintained in a cold environment soon after injury. In conclusion, our results suggest that there is potential for broadening the ischemia time limits for digit replant survival outlined in the literature, particularly for digits that have been stored correctly in cold ischemia.

Analyzing attempt and success factors for amputated digit replantation in Japan using the diagnosis procedure combination database.

The number of amputated finger replantation has declined in the USA and Germany in recent years; however, there have been no reports on recent trends in Japan. We examined the current practices, attempts, and success factors of digit replantation in Japan. We hypothesized that the rates of digit replantation and success rates were consistently standardized in Japan. The diagnosis procedure combination database was used to analyze 14004 cases from April 2014 to March 2020, excluding multiple-digit amputations, thus focusing on 13484 patients. We evaluated replantation success rates and identified factors influencing replantation decisions using multiple logistic regression analysis. The key findings included a higher frequency of replantation in thumb cases and surgeries during overtime hours, on Sundays, and in educational institutions. Success rates were notably higher for thumb replantations and patients under 20 years of age. Patients over 65 years of age treated with urokinase showed higher failure rates, unrelated to regional or hospital case volumes. The number of amputated digit replantation surgeries in Japan was high during overtime hours, on Sundays, and in educational institutions. Region, hospital type, and hospital case volume were not associated with a low success rate across Japan.

Bone grafting combined with a spiral flap technique for the reconstruction of fingertip amputations.

BACKGROUND: Various reconstructive options exist for distal finger and pulp defects, including grafting and local or distant flaps. In addition to reconstructing the normal anatomical structure, preserving the sensory function of the finger is crucial. This study presents the results of using bone grafting combined with a spiral flap (BGcSF) technique for reconstructing pulp defects accompanied by bone loss. METHODS: Twenty-three patients with fingertip defects were treated using the BGcSF technique. Flap sensitivity was assessed us-ing the Semmes-Weinstein monofilament (SWM) and static two-point discrimination (2PD) tests at six months postoperatively. Cold intolerance of the affected fingers was evaluated using the Cold Intolerance Severity Score (CISS) questionnaire at one year postop-eratively. Patient satisfaction was assessed using the Michigan Hand Outcomes Questionnaire (MHQ). Range of motion (ROM) for the proximal and distal interphalangeal joints was measured with a goniometer at one year postoperatively. RESULTS: Distal flap necrosis, affecting 10-15% of the flap area, was observed in one patient. No other complications were noted. The mean static two-point discrimination value at six months postoperatively was 5.6 mm, and the mean SWM score was 3.56. The mean CISS score at one year postoperatively was 18.8. The mean active ROM angle for the proximal interphalangeal joint was 106.7 degrees, and for the distal interphalangeal joint, it was 65.4 degrees. The mean MHQ score at one year postoperatively was 18.5. CONCLUSION: The BGcSF technique provides soft tissue with a texture similar to that of the fingertips and supports effective sensory repair. It can be considered a viable option for fingertip reconstruction in cases where replantation is not feasible.

[Effectiveness of Kirschner wire fixation for proximal phalangeal bone avulsion fracture caused by A2 circular trochlea injury of flexor digitorum tendon].

Objective: To explore the mechanism, surgical method, and effectiveness of proximal phalangeal bone avulsion fracture caused by A2 circular trochlea injury of the flexor digitorum tendon. Methods: A retrospective analysis was conducted on the clinical data of 4 patients with proximal phalangeal bone avulsion fracture caused by A2 circular trochlea injury of flexor digitorum tendon admitted between May 2018 and September 2022. The patients were all male, the age ranged from 26 to 52 years, with an average of 33 years. The injured fingers included 1 case of middle finger and 3 cases of ring finger. The causes of injury were rock climbing of 2 cases and carrying heavy objects of 2 cases. Preoperative anteroposterior and lateral X-ray films and CT examination of the fingers showed a lateral avulsion fracture of the proximal phalanx, with a fracture block length of 15-22 mm and a width of 3-5 mm. The total active range of motion (TAM) of the injured finger before operation was (148.75±10.11)°. The grip strength of the middle and ring fingers was (15.50±2.88) kg, which was significantly lower than that of the healthy side (50.50±7.93) kg ( t=-8.280, P<0.001). The time from injury to operation was 2-7 days, with an average of 3.5 days. One Kirschner wire with a diameter of 1.0 mm was used for direct fixation through the fracture block, while two Kirschner wires with a diameter of 1.0 mm were used for compression fixation against the fracture block. The fracture healing was observed, and the TAM of the injured finger and the grip strength of the middle and ring fingers were measured. The finger function was evaluated according to the upper limb functional assessment trial standards of the Chinese Medical Association Hand Surgery Society. Results: The incisions all healed by first intention after operation. All patients were followed up 6-28 months, with an average of 19 months. X-ray films showed that all avulsion fractures of proximal phalanx reached bony union, and the healing time ranged from 4 to 8 weeks, with an average of 4.6 weeks. At last follow-up, the grip strength of the middle and ring fingers was (50.50±7.76) kg, which significantly improved when compared with preoperative one ( t=-8.440, P<0.001). The TAM of the injured finger reached (265.50±2.08)°, and there was a significant difference when compared with preoperative one ( t=-21.235, P<0.001). According to the upper limb functional assessment trial standards of the Chinese Medical Association Hand Surgery Society, the finger function was all evaluated as excellent in 4 cases. Conclusion: Using Kirschner wire fixation through bone blocks and external compression fixation of bone blocks for treating proximal phalangeal bone avulsion fracture caused by A2 circular trochlear injury of the flexor digitorum tendon can achieve good effectiveness.

Pins and Rubbers Traction System for Treatment of Intraarticular Fractures of Distal Interphalangeal Joint.

Background: The pins and rubber traction system (PRTS) has proven effective in managing intra-articular fractures of the proximal interphalangeal joint. However, there is scant evidence in the literature regarding its efficacy in treating distal interphalangeal joint (DIPJ). This study aims to investigate the outcomes of PRTS in the treatment of comminuted intra-articular fractures of the DIPJ. Methods: We conducted a retrospective review of patients with comminuted intra-articular fractures of the DIPJ treated with PRTS between 2017 and 2021. At the final follow-up, we measured and compared the active range of motion (ROM) in both affected and non-injured contralateral fingers. The subjective evaluation utilised the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and the Visual Analogue Scale (VAS). Results: Ten patients with a mean follow-up of 13.2 months (range: 12-17) were included in the study. Fracture locations included the base of the distal phalanx in two patients, the condyle of the middle phalanx in seven and both in one patient. At the final follow-up, the average VAS score was 0.5 (range: 0-2). The average active motion of the DIPJ was 61° (range: 50°-70°) for the injured side and 76° (range: 75°-80°) for the opposite side. The mean range of DIPJ movement was 80% (range: 68%-87%) of the non-injured side. Extension deficits were observed in five patients, with a median deficit value of 10° (range: 5°-10°). The average Quick-DASH score was 2.9 (range: 0-11.3). Conclusions: The PRTS can be considered as an effective surgical technique in managing comminuted intra-articular fractures of the DIPJ. Level of Evidence: Level IV (Therapeutic).

A Review on Volar Fracture-Dislocations of the Proximal Interphalangeal Joint.

Volar fracture-dislocations of the proximal interphalangeal joint are rare injuries caused by an axial force on a flexed digit resulting in an avulsion fracture of the dorsal lip of the middle phalanx with volar dislocation of the joint. This volar subtype is analogous to the more common dorsal subtype with a mirror image fracture on the dorsal lip of the middle phalanx. The main significance in this type of injury lies in the disruption of the extensor mechanism at the central slip. The goals of treatment, apart from restoring a congruent and stable joint, is to restore the extensor mechanism to prevent a boutonnière deformity. In this article, we summarise the current literature and discuss the principles for treatment of this uncommon injury. Level of Evidence: Level V (Therapeutic).

One-stage secondary debulking procedure: A unique technique to restore the differential contour of digit after groin flap reconstruction.

BACKGROUND: Pedicled groin flap is a reliable reconstructive method for digits. However, problems with the contour, mobility, and sensation, especially while providing strict thin skin coverage still exist. PATIENTS AND METHODS: A total of 17 cases with 36 digits injured by trauma were identified. One-stage secondary debulking procedure was adopted for flap revision. The skin over the flap was harvested as a full-thickness graft. At the dorsal side of the reconstructed digit, the subcutaneous tissue and fat were debulked till the deep fascial layer. At the volar side, the flap was debulked till the superficial fascial layer. The skin was then re-grafted. The outcomes were reviewed after 12 months follow-up. RESULTS: The average timing for debulking procedure after flap reconstruction was 116 days. After removal of bolster dressing 7 days after debulking, all the grafted skin took well. A mean length of 2.5 cm of digit was preserved for the non-replantable digits. The reconstructed digits achieved comparable diameter and contour with that of the contralateral side. The two-point discrimination of the injured digits of adults was 10.4 ± 1.6 mm. Using a 5-point Likert scale, post-debulking digits showed statistically significant improvement compared to pre-debulking digits. The evaluation of the patients' satisfactory outcomes of the reconstructed digits was judged as "very satisfying" in 12 patients (75 %) and "good" in 4 patients (25 %). CONCLUSIONS: One-stage secondary debulking procedure resulted in excellent functional and esthetic outcomes for digits according to different structures of the dorsal and volar sides. LEVEL OF EVIDENCE: IV, Retrospective.

Nail bed trauma reconstruction and artificial nail replacement - a case report.

Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed's remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed's shape. Temporary artificial nail replacements protect the regenerating fingertip bed, promote healing, and prevent nail deformities. Proper adaptation of lacerated nail bed edges, supported by either the patient's own nail or a temporary artificial nail, is crucial for optimal fingertip restoration, including proper nail shape.

Extensor tendon rupture and preoperative mri confirmations of suture anchor prolapse: a case report and literature review.

BACKGROUND: While suture anchors are widely used in medical procedures for their advantages, they can sometimes lead to complications, including anchor prolapse. This article presents a unique case of suture anchor prolapse at the base of the distal phalanx of the little finger after extensor tendon rupture reconstruction surgery. CASE PRESENTATION: A 35-year-old male, underwent extensor tendon rupture reconstruction using a non-absorbable suture anchor. After seven years the patient visited our outpatients complaining of stiffness, pain, and protrusion at the surgical site. Initial X-ray imaging suggested suggesting either a fracture of the distal phalanx or tendon adhesion but lacked a definitive diagnosis. Subsequent magnetic resonance imaging (MRI) revealed bone connectivity between the middle and distal phalanges with irregular signal shadow and unclear boundaries while maintaining a regular finger shape. MRI proved superior in diagnosing prolapsed suture anchors, marking the first reported case of its kind. Surgical intervention confirmed MRI findings. CONCLUSIONS: Suture anchor complications, such as prolapse, are a concern in medical practice. This case underscores the significance of MRI for accurate diagnosis and the importance of tailored surgical management in addressing this uncommon complication.
