Abstract
SUMMARY Delayed or missed diagnosis of perilunate or lunate dislocations can lead to significant morbidity. Advances in computer vision provide an opportunity to improve diagnostic performance. In this study, a deep learning algorithm was used for detection of perilunate and lunate dislocations on lateral wrist radiographs. A total of 435 lateral wrist radiographs were labeled as normal or pathologic (perilunate or lunate dislocation). The lunate in each radiograph was segmented with a rectangular bounding box. Images were partitioned into training and test sets. Two neural networks, consisting of an object detector followed by an image classifier, were applied in series. First, the object detection module was used to localize the lunate. Next, the image classifier performed a binary classification for normal or pathologic. The accuracy, sensitivity, and specificity of the overall system were evaluated. A receiver operating characteristic curve and the associated area under the curve were used to demonstrate the overall performance of the computer vision algorithm. The lunate object detector was 97.0% accurate at identifying the lunate. Accuracy was 98.7% among the subgroup of normal wrist radiographs and 91.3% among the subgroup of wrist radiographs with perilunate/lunate dislocations. The perilunate/lunate dislocation classifier had a sensitivity (recall) of 93.8%, a specificity of 93.3%, and an accuracy of 93.4%. The area under the curve was 0.986. The authors have developed a proof-of-concept computer vision system for diagnosis of perilunate/lunate dislocations on lateral wrist radiographs. This novel deep learning algorithm has potential to improve clinical sensitivity to ultimately prevent delayed or missed diagnosis of these injuries.

Abstract
BACKGROUND Perilunate dislocations and perilunate fracture dislocations (PLD/PLFDs) are rare injuries of the wrist, with surgical management leading to acceptable functional results. PURPOSE The purpose of this study was to assess the functional outcomes of the patients of our department who were treated with surgical management of PLDs/PLFDs through dorsal approach, as well as to report any complications on their follow-up. PATIENTS AND METHODS In this retrospective study, 52 patients with PLD/PLFD, fulfilling the inclusion and exclusion criteria of the study, underwent surgical management of their injury. All patients were followed up at 6 weeks, 12 weeks, 6 months, 1 year postoperatively with radiographic imaging as well as functional scores measured with the modified mayo wrist score and the QuickDASH questionnaire. RESULTS The mean postoperative modified Mayo score was 76.8 ± 8.8 and the mean QuickDASH score was 1.52 ± 2.18. Of the 52 cases, 20% had excellent results, 42% had good results, 29% had fair results and 9% had poor results as per the modified Mayo wrist score. No patient signed any symptoms of median nerve neuropathy. CONCLUSION In conclusion, open reduction and internal fixation through dorsal approach is a reliable technique to manage perilunate injuries in spite of radiological evidence of wrist arthritis, as it also provides consistently good results in terms of functional outcomes. LEVEL OF EVIDENCE IV Retrospective case series study.

Abstract
BACKGROUND Perilunate dislocations (PLD) and fracture-dislocations (PLFD) comprise a spectrum of high-energy wrist injuries. The purpose of this review was to review operative strategies for perilunate injuries based on approach and compare outcomes. METHODS A systematic review of literature on PLD and fracture-dislocations was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed and EMBASE databases were queried for literature. Inclusion criteria included English studies reporting clinical or functional outcomes of acute PLD and PLFD. RESULTS Twenty-nine full-text articles (604 PLD and PLFD injuries) were included. The most common method of PLD and PLFD fixation is through an open approach with combined volar and dorsal exposure. There were no differences between approaches with regard to total arc range of motion, grip strength, Mayo Wrist Score, or mean scapholunate angle. Similarly, there was no difference between approaches and postoperative radiographic arthritis or complications. Most patients were able to return to their prior level of function and work. The incidence of postoperative complications ranged from 0% to 22.5%. CONCLUSION Current evidence shows no difference in postoperative total wrist arc range of motion, grip strength (as compared to contralateral), or Mayo Wrist Score with regard to surgical approach. The most common method of PLD and PLFD fixation in the literature is through an open approach with combined volar and dorsal exposure. There is a large difference in reported rates of radiographic arthritis, although this finding does not appear to correlate with postoperative pain or disability.

Abstract
Background Perilunate injuries are complex injuries typically arising from high-energy injuries to the wrist. Standard treatment involves open reduction and internal fixation with ligamentous reconstruction; however, outcomes are fraught with complications including pain, stiffness, and arthrosis. Several case reports have demonstrated the role of proximal row carpectomy as a salvage procedure for complex carpal trauma in the setting of significant cartilage injury or bone loss. The authors believe that proximal row carpectomy may be an appropriate acute treatment in certain patient populations, with functional results similar to those obtained with ligamentous reconstruction. Methods A retrospective review of two cases with perilunate dislocations managed with primary proximal row carpectomy are presented. Results At greater than 1-year follow-up, both patients had stable radiocarpal alignment. Quick-DASH scores were 22.7 and 27.3. Conclusion Primary proximal row carpectomy is a treatment option in the acute setting for perilunate injuries in elderly, lower-demand patients. Functional results are similar to those obtained with ligamentous reconstruction, with a shorter recovery period. Level of Evidence: IV.

Abstract
PURPOSE The objective of this systematic review was to perform epidemiological as well as clinical, radiological and patient-reported outcome analysis of surgically treated perilunate dislocations and fracture dislocations (PLDs and PLFDs) based on the so far largest pooled patient population to date. MATERIAL AND METHODS This systematic review was written according to the updated guideline for reporting systematic reviews by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. A comprehensive literature search of Pubmed, Embase, CENTRAL, and CINAHL databases was performed. All studies reporting on complications, radiological, functional and/or patient-reported outcomes of surgically treated acute PLDs and PLFDs with a minimum follow-up of 12 months were included. RESULTS Twenty-six studies encompassing 550 patients with 553 operatively treated acute perilunate injuries (106 PLDs and 447 PLFDs) were included. The overall postoperative complication rate was 15.0% with secondary reduction loss representing the main contributing factor (10.1%). The overall reoperation rate was 10.4% and the incidence of salvage procedures was 2.8%. The risk for secondary reduction loss was higher for PLD than for PLFD injuries (24.2% vs. 7.0%, relative risk [RR] 3.5, 95% confidence interval [CI] 1.6-7.5). There was a higher overall complication rate for the combined dorsopalmar approach when compared to the isolated dorsal approach (17.4% vs. 8.4%, RR 0.5, 95% CI 0.2-1.0, number needed to treat [NNT] 11.2) and for open surgery versus arthroscopic surgery (17.4% vs. 4.8%, RR 0.3, 95% CI 0.1-0.9, NNT 8.0). A significant correlation was found between radiological osteoarthritis (rOA) and follow-up duration of the individual studies, while functional and patient-rated outcomes were comparable. CONCLUSIONS Regardless of surgical technique, PLFDs appear to be less susceptible to secondary reduction loss than PLDs. Whenever possible, less invasive (e.g. arthroscopic) surgery should be performed to minimize postoperative complications. The rate of rOA is high and increases significantly with follow-up duration. Interestingly, rOA does not seem to correlate with reduced wrist function nor patient dissatisfaction and the need for salvage surgery is surprisingly rare. LEVEL OF EVIDENCE Systematic review of level IV studies.

Abstract
Background The all-dorsal scapholunate reconstruction technique is indicated for the treatment of scapholunate injuries in cases in which the carpus is reducible and there is no arthrosis present. The goal of this procedure is to reconstruct the torn dorsal portion of the scapholunate ligament in order to stabilize the scaphoid and lunate. Description A standard dorsal approach to the wrist, extending from the third metacarpal distally to the distal radioulnar joint, is utilized. The extensor pollicis longus is transposed and retracted radially, and the second and fourth extensor compartments are retracted ulnarly. A Berger ligament-sparing capsulotomy is utilized to visualize the carpus. Volarly, an extended open carpal tunnel release is also utilized to relieve any median nerve compression and to aid in reduction. The contents of the carpal tunnel can be retracted radially, allowing for visualization of the carpal bones. Joystick pins are placed in order to reduce the scaphoid and lunate. Reduction is held provisionally by clamping the pins until 4 pins can be placed across the carpal bones. For scapholunate reconstruction, 3 holes are made: in the lunate, proximal scaphoid, and distal scaphoid. Suture tape is then utilized to hold the scaphoid and lunate in their proper position. The dorsal wrist capsule and extensor retinaculum are repaired during closure. The pins are cut near the skin and are removed in 8 to 12 weeks. Alternatives Several other methods of scapholunate reconstruction have been described, including capsulodesis, tenodesis, and bone-tissue-bone repairs. Additionally, in patients who are poor candidates for scapholunate reconstruction, wrist-salvage procedures can be utilized as the primary treatment. Rationale Scapholunate reconstruction has the advantage of preserving the native physiologic motion of the wrist, in contrast to the many different wrist-salvage procedures that include arthrodesis or arthroplasty. Avoiding arthrodesis is specifically advantageous in patients who have not yet developed arthrosis of the wrist bones. Expected Outcomes Outcomes of scapholunate reconstruction vary widely; however, there is a nearly universal decrease in range of motion and strength of the wrist. Wrist range of motion is typically 55% to 75% of the contralateral side, and grip strength is typically approximately 65% of the contralateral side. In a prior study, 50% to 60% of patients whose work involved physical labor were able to return to their same level of full-time work. Disabilities of the Arm, Shoulder and Hand scores average between 24 and 30. Specific patients at risk for inferior outcomes are those with delayed surgical treatment, poor carpal alignment following reduction, or open injuries. Important Tips Patients are counseled preoperatively regarding the likelihood of permanent wrist stiffness and the possibility of scapholunate diastasis even in the setting of technically successful repair.Traction and dorsally directed pressure on the lunate through an extended carpal tunnel incision can aid in reduction of the lunate.The joystick pin position in the dorsal scaphoid is angulated from distal to proximal and that in the lunate is angulated from proximal to distal in order to help correct flexion of the scaphoid and extension of the lunate by clamping together the Kirschner wires. Modifying the distance of the clamp from the carpus can allow precision in the degree of scapholunate angle fixation.Intercarpal Kirschner wire fixation of the scapholunate, lunotriquetral, and midcarpal joints (scaphocapitate and triquetrohamate) is best performed with 0.062-in (1.6-mm) Kirschner wires. The insertion angle is best visualized when the Kirschner wire is introduced from inside the incision through the skin, "inside out," in order to best envision the trajectory on the dorsal carpus and define the starting point on the bone. The Kirschner wire is then advanced through the carpus from outside-in at a slightly more volarly translated (but not angulated) position. The Kirschner wires are then cut beneath the skin at a depth that will allow them to be retrieved but will not cause them to become exposed once swelling decreases.The wrist is generally immobilized until the pins are removed at 3 months postoperatively.

Abstract
Carpal dislocations result from sequential disruption of the complex relationship between the bones and ligaments of the wrist. Injuries to the carpus occur via predictable mechanisms, an understanding of which is critical to identify and treat these frequently missed patterns of injury and to avoid the sequela of chronic instability. Lunate dislocations are by far the most common, but isolated dislocation of other carpal bones can also occur. Open reduction and internal fixation still remains the gold standard for treatment regardless of the debate around the specific approaches. These high-energy injuries are associated with significant long-term morbidity even when identified promptly and appropriately treated. This review will focus on the evaluation and management of common forms of carpal dislocations.

Abstract
Introduction Perilunate dislocations and perilunate fracture-dislocations (PLFD) are relatively uncommon injuries, comprising <10% of wrist injuries. Perilunate injuries are often complicated by median neuropathy reported in 23-45% of cases, whereas there are very few reported cases of associated ulnar neuropathy. Combined greater arc and inferior arc injuries are also rare. We report an unusual PLFD pattern with associated inferior arc injury and acute ulnar nerve compression. Case Report A 34-year-old male sustained a wrist injury after a motorcycle collision. Computed tomography scan revealed a trans-scaphoid, transcapitate, perilunate fracture-dislocation, and a distal radius lunate facet volar rim fracture with radiocarpal subluxation. Examination revealed acute ulnar neuropathy without median neuropathy. He underwent urgent nerve decompression and closed reduction, followed by open reduction internal fixation the next day. He recovered without complication. Conclusion This case emphasizes the importance of a thorough neurovascular examination to rule out less commonly seen neuropathies. With up to 25% of perilunate injuries misdiagnosed, surgeons should have a low threshold for advanced imaging in high-energy injuries.

Abstract
Introduction Perilunate injuries are uncommon yet challenging and often missed injuries, representing 7% of all carpal traumas. Two types of injuries can be identified as follows: perilunate dislocations (PLD) and perilunate fracture-dislocations (PLFD). The purpose of this study was to conduct a systematic review and meta-analysis to establish which surgical treatment is superior for patients with perilunate injuries and the significance of delayed treatment. Methods A total of 2056 articles were screened, and 16 articles were included. Risk of bias for case-control series and case series were assessed through the National Institute of Health study quality assessment tool. Qualitative outcomes of clinical scores for hand function were compared between different time points (acute, < 7 days; delayed 7-45 days; chronic > 45 days), open and closed reduction, and PLD and PLFD. Results Overall, the clinical outcome scores of patients treated within 7 days are good. The results suggest that closed reduction and internal fixation (CRIF) offers slightly better outcomes than open reduction and internal fixation (ORIF) for PLFD. Patients treated 6 weeks or more after the initial injury seem to have the worst overall outcomes than patients in the acute or delayed setting. The results suggest that patients with chronic PLD have even worse outcomes than patients with chronic PLFD. Conclusions Timing of surgery is essential for an optimal outcome. When there is a delay of treatment, the outcomes are inferior to those treated acutely. Early referral to centralized treatment units for perilunate injuries would allow for targeted treatment and facilitate research on this difficult wrist injury.

Abstract
INTRODUCTION Perilunate lesions in the carpus are severe injuries whose functional consequences can limit patients' ability to regain their pre-injury activity levels. The aim of this study was to evaluate the outcomes of a series of patients who suffered a perilunate fracture-dislocation and to assess their ability to resume their social and professional activities. HYPOTHESIS After surgical management of this injury, the medium-term functional outcomes will allow patients to return to their pre-injury social and professional activities. MATERIALS AND METHODS This was a single center, retrospective study. Included patients were adults who had suffered a perilunate fracture-dislocation that was treated emergently. The clinical and functional assessment consisted of comparing the mobility and grip strength between the injured and contralateral wrists, determining the functional outcome scores and the resumption of social and professional activities. A radiological assessment was done to look for instability of the proximal row of the carpus, nonunion or necrosis of the carpal bones, loss of carpal height, and presence of carpal osteoarthritis. RESULTS Ten patients were included with a mean follow-up of 39.4 months. The mean flexion/extension arc decreased significantly to 88° (20°-150) which was 55% of the healthy contralateral side (p=0.0026) while the grip strength decreased but not significantly (40.6 Kg vs. healthy side 62.4 Kg, p=0.063). The mean MWS was 58.75 (40-100), the mean PRWE was 32.9 (4-67.5) and the mean QuickDASH was 30.2 (0-77). Six of the ten patients (60%) were able to return to work, although three required occupational reclassifications. Four patients had signs of proximal row instability. There were seven instances of radiocarpal osteoarthritis, two of which were combined with mid-carpal osteoarthritis. DISCUSSION This study found shorter range of motion and worse patient-reported outcomes than other published studies, which may be due to the severity of the perilunate fracture-dislocation injuries and the inclusion of polytrauma patients. Nevertheless, the subjective scores were comparable. These injuries have serious consequences on social and professional activities of manual workers. LEVEL OF EVIDENCE IV; retrospective study.

Anatomic dissection was performed and vascularity of the lunate was identified, its origin is from the volar palmar arch, when dislocated palmarly and more than 90 degrees the vessel is still intact. More than 512 patients with perilunate dislocation and perilunate fracture dislocation are included we identified in the literature transient avascular necrosis of the lunate in nine and seventeen of pure avascular necrosis of the lunate. Concluding that avascular necrosis of the lunate after perilunate dislocation or perilunate fracture dislocation is an infrequent finding especially when the volar ligaments are intact.

Abstract
Objectives
The present study aimed to evaluate the diagnostic failure rate in detecting perilunate fractures and dislocations using plain wrist radiographs by orthopedists and orthopedic residents. A secondary objective was to identify possible groups with a greater or lesser chance of establishing a correct diagnosis.
Methods
An online questionnaire was sent to several orthopedists through e-mail, social networks, and smartphone-based communication applications to assess the rate of diagnostic failure in detecting perilunate fractures and dislocations using plain radiographs.
Results
A total of 511 responses was obtained, with a diagnostic error rate of 8.81% for simple dislocations and 1.76% for trans-scaphoid perilunate fractures. Group stratification showed that residents presented the highest error rates in simple perilunate dislocations (23.91%), whereas hand surgeons presented the lowest error rates (1.74%).
Conclusion
Compared with the literature, the failure rates found were lower, suggesting that plain radiography is effective and that the error rate may not be as high as reported.

Abstract
OBJECTIVE This study aimed to present the mid-term clinical and radiographic outcomes of patients with perilunate injuries treated with open reduction and internal fixation (ORIF). METHODS Patients who underwent ORIF due to perilunate injuries from 2004 to 2015 were retrospectively reviewed. Surgery was mostly performed using a standard dorsal approach. Each injury was graded as per Mayfield staging. At the final follow-up, pain intensity was evaluated using a 10-cm visual analog scale (VAS). Wrist and elbow range of motion, handgrip and pinch strength, Modified Mayo Wrist Scores, and the disabilities of the arm, shoulder, and hand (DASH) scores were measured. On plain radiographic examination, the scapholunate (SL) angle, SL interval, carpal height, and continuity of Gilula arcs were evaluated. The presence of arthritis was also assessed using the Herzberg classification. RESULTS In total, 26 male patients (27 wrists) who met the inclusion criteria were included in the study. The mean age was 40 years (range: 20-58); the mean follow-up was 45 months (range: 16-96). Most of the injuries were fracture-dislocations (n=20; 71.4%). According to Mayfield staging, 7 wrists were grade 3, and 20 wrists were grade 4. According to Herzberg staging, 11 (40.7%) patients were stage 2a. The mean VAS was 2.3 (range: 0-5) at rest and 3.3 (range: 0-7) during activity. The mean wrist flexion and extension were 50° (range: 21-80°; 73.5% of the unaffected side) and 45.1° (range: 20-74°; 70.9% of the unaffected side), respectively. The mean radial and ulnar deviation were 14.6° (range: 6-25°; 63.6% of the unaffected side) and 22.3° (range: 5-40°; 64.7% of the unaffected side), respectively. Grip and pinch strength were 57.6 kg (range: 15-106; 65.5% of the unaffected side) and 18.6 kg (range: 8-28; 78.2% of the unaffected side), respectively. The mean Mayo score was 63.3 (range: 20-90), and the DASH score was 24.1±25.2. The mean SL angle was 61.6° (range: 40-83). There was 1 wrist with a pathological SL interval, 11 wrists with dorsal intercalated segmental instability, and 3 wrists with fractures of the Gilula arcs. The mean carpal height was within the normal range. CONCLUSION In the treatment of perilunate injuries, satisfactory clinical and radiographic outcomes can be expected from ORIF at mid-term follow-up. LEVEL OF EVIDENCE Level IV, Therapeutic Study.

Abstract
The most common etiology of carpal tunnel syndrome (CTS) is idiopathic. However, secondary causes of CTS should be considered when symptoms are unilateral, or electrodiagnostic studies are discrepant with the clinical presentation. Imaging of the carpal tunnel should be performed when secondary causes of CTS are suspected. An ultrasound evaluation of the carpal tunnel can assess for pathologic changes of the median nerve, detect secondary causes of CTS, and aid in surgical planning.

Treatment of acute perilunate dislocation or fracture dislocation using dorsal approach and diamond-shaped Kirschner-wire fixation. Jt Dis Relat Surg 2020; 32:42-50. [PMID: 33463417 PMCID: PMC8073432 DOI: 10.5606/ehc.2021.74838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 08/04/2020] [Indexed: 11/21/2022] Open
Abstract
Objectives
This study aims to evaluate the clinical and radiological outcomes of diamond-shaped Kirschner (K)-wire fixation for the treatment of acute perilunate dislocation (PLD) or trans-scaphoid perilunate fracture dislocation (PLFD). Patients and methods
We performed a retrospective review of 18 patients (18 wrists; 17 males, 1 female; mean age 31.5±2.6 years; range, 18 to 47 years) treated for PLD/PLFD using a dorsal approach with the diamond-shaped K-wire fixation between November 2001 and September 2017. The mean follow-up of cohort was 27 (range, 13 to 74) months. Using a dorsal approach, open ligament repair and bone fixations were performed. Perilunate dislocation was reduced and the carpal bones and midcarpal joint were held in anatomical position using four K-wires transfixing the scapholunate (SL), lunotriquetral, scaphocapitate, and triquetrohamate joints in such a shape that each bone received two K-wires. Results
The mean range of motion and grip strength measured using a Jamar® dynamometer of the injured wrist compared to the uninjured extremity were 84.3% and 78.8%, respectively. The mean Mayo wrist score was 78.3 (range, 70 to 90). The mean Visual Analog Scale score was 1.2 (range, 0 to 4). The average SL gap at the final follow-up evaluation was 1.62 (range, 1 to 2.3) mm. The mean SL and capitolunate angles were 49.3° (range, 40 to 75°) and 4.2° (range, 2 to 12°), respectively. Conclusion
Because every bone is fixed with two K-wires using this configuration, a closed ring is created; hence no motion is possible between the scaphoid, capitate, hamate, triquetrum, lunate and the midcarpal joint. We believe that diamond-shaped fixation may provide reliable fixation and satisfactory clinical outcomes in patients with PLD and PLFD.
