RESUMEN
OBJECTIVE: This study aims to evaluate the outcomes of open reduction and internal fixation (ORIF) for chronic perilunate dislocations using single-stage, two-stage, and salvage procedures. The study also compares these approaches with each other and with results from existing literature. METHODS: A total of 15 patients with chronic perilunate injuries from 2013 to 2019 were included in the study. Pre-operative and post-operative assessments were conducted using plain radiographs, with CT scans performed selectively for detailed morphology and fracture pattern analysis. Among the patients, 13 underwent ORIF, while 2 underwent salvage procedures. Among the ORIF cases, single-stage procedures were performed in 4 patients, and two-stage procedures in 9 patients. External fixators, including unilateral uniplanar external fixators (UUEF) and bilateral uniplanar external fixators (BUEF), were applied in 5 and 4 patients, respectively. Our methodology of treating chronic perilunate injuries has evolved over the years. We started with single stage ORIF then graduated to a two staged procedure initially using a external fixator as a carpal distractor applied only on the radial side and finally settling down with bilateral carpal distraction using external fixators both on the radial and ulnar sides. RESULTS: Among the 15 patients, 3 were lost to follow-up. Of these, one underwent four-corner fusion, while the remaining two had UUEF. The mean time interval between injury and surgery was 3.60 months. The post-operative mean scapholunate angle measured 52.46°, with a negative radio-lunate angle (indicating flexion) observed in two patients, while others showed a positive angle (indicating extension). Two cases exhibited nonunion and avascular necrosis (AVN) of the scaphoid, while one case presented with lunate AVN. Mid-carpal and radio-carpal arthritis was observed in 4 and 2 patients, respectively. Functional outcomes were evaluated using Mayo's wrist score categorized as good for two-stage BUEF cases and satisfactory for UUEF and single-stage procedures. CONCLUSION: Staged reduction utilizing the BUEF followed by open reduction has demonstrated superior outcomes when compared to UUEF, single-stage open reduction and salvage procedures. LEVEL OF EVIDENCE: 4.

BACKGROUND: There are several surgical options for osteonecrosis of the lunate, and confirming the effectiveness of various surgical methods remains challenging. Here, we present a case of stage IIIB osteonecrosis of the lunate repaired with a free medial femoral condyle osteocutaneous flap. CASE PRESENTATION: A 43-year-old male construction worker was admitted to our hospital due to right wrist pain, impaired mobility, and pain aggravated by activity for 10 months. The patient was diagnosed with stage IIIB osteonecrosis of the lunate based on the orthopantomogram and magnetic resonance imaging of the right wrist. Considering the patient's medical history, physical examination, auxiliary examination, and wishes, reconstruction was performed using a free medial femoral condyle osteocutaneous flap. After the flap survived completely, the K-wires were removed one month after the operation, the external brace was removed two months after the operation, and functional wrist rehabilitation was initiated. After six months of follow-up, the wrist swelling and pain resolved, and the reconstructed lunate bone was viable. Additionally, the last follow-up was conducted in the sixth month after surgery; the affected hand grip strength improved from about 70% (28 kg) to 80% (32 kg) compared with the healthy side (40 kg); the visual analog scale score decreased from 6.5 points before the operation to 1 point; and the MAYO score increased from 60 points before the operation to 85 points. CONCLUSIONS: The success of this case reinforces the potential of the free medial femoral condyle osteocutaneous flap as a new treatment option for stage IIIB osteonecrosis of the lunate and further expands the existing treatment options. Using a free medial femoral condyle osteocutaneous flap to reconstruct the lunate and restore the carpal anatomy may.

OBJECTIVES: This study aimed to assess clinical, functional and radiological outcomes after three-corner arthrodesis in patients suffering from symptomatic scapholunate or scaphoid non-union advanced collapsed wrists. We hypothesised that three-corner arthrodesis provided satisfactory clinical and radiological results in the long term. MATERIAL AND METHODS: This was a retrospective study of 13 patients (14 wrists) who underwent a three-corner arthrodesis between March 2004 and January 2019 with a mean follow-up of 6,7 years. Clinical assessment consisted of wrist motion, grip strength, pain and functional scores (Quick-DASH, PRWE, MWS). All complications and surgical revisions were investigated. Radiographic assessment searched for union, evaluated carpal height and ulnar translation, lunate tilt and occurrence of radio-lunate arthritis. RESULTS: At the last follow-up Quick-DASH and PRWE scores were 24,87(± 17.2) and 47.4 (± 26.9) respectively and were significantly improved. Wrist motion was 35°, 32°, 10° et 24° of flexion, extension, radial and ulnar deviation respectively. Union was obtained for 13 (92,9%) wrists. The mean radiolunate angle was 11° (-17°-34°). Three patients needed reintervention, which 2 consisted of total wrist arthrodesis due to persisting pain. Mild signs of radio-lunate arthritis were found in three patients. CONCLUSION: Three-corner arthrodesis seemed to provide satisfactory long-term functional outcomes. The union rate was high and even patients with signs of radio-lunate arthritis still had improved outcomes at the last follow-up. It could be a part of surgical options in wrists with radio- and midcarpal arthritis, among other procedures.

CASE: A 32-year-old woman with bilateral Madelung deformity presented with severe pain and arthritis of the radiocarpal and distal radioulnar joints. At final follow-up, 17 months for the left and 12 months for the right wrist, she had excellent functional results with no pain. Range of motion was 30° of flexion and 30° of extension with full pronosupination. CONCLUSION: There is paucity in the literature regarding salvage procedures in adults with this deformity. We demonstrate treatment with distal ulna excision and an radioscapholunate arthrodesis. This procedure may be indicated in Madelung deformity and proximal radiocarpal and distal radioulnar joint arthritis.

Background: Perilunate fracture-dislocations are frequently associated with a high risk of developing post-traumatic arthritis. Current studies indicate that during mid-term follow-ups, radiological signs of arthritis do not appear to correspond with functional score. The aim of this study was to assess the occurrence of posttraumatic arthritis and the wrist function after perilunate dislocations (PLD) and fracture dislocations at a mid-term follow-up of 7 years. Methods: We report the clinical and radiological outcomes of 17 wrists treated for PLD or fracture-dislocation by open reduction and internal fixation through a dorsal approach with dorsal ligament repair. Functional outcomes were evaluated using the short version of the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), the Patient-Rated Wrist Evaluation questionnaire (PRWE) and the Mayo Wrist Score (MWS). Results of radiographs were assessed using the Herzberg Radiological Scoring Chart. Results: The MWS showed five excellent, five good, five fair and two poor results with an average score of 81%. Radiological analysis using the Herzberg classification revealed midcarpal and/or radiocarpal arthritis in 65% of cases, lunate collapse in 59% and an increase in the mean ulnar translocation ratio in 53% of the cases. Complications included one case of lunate osteonecrosis and one case of stage 3 scapholunate advanced collapse that required revision surgery. Conclusions: Although the clinical and functional outcomes are favourable at mid-term follow-up, radiological evaluation shows a progression towards osteoarthritis (OA). Further research is warranted to refine treatment strategies and investigate factors influencing the development of OA. Level of Evidence: Level IV (Therapeutic).

Trans-scaphoid perilunate fractures-dislocations are rare injuries caused by high-energy trauma of the wrist. Diagnosis is based on medical history, physical examination, and tools such as radiographs, computed tomography scan, and magnetic resonance imaging. Early treatment consists of closed reduction and casting to stabilize the limb. Definitive treatment is surgical and includes bone and soft tissue repair. A case of trans-scaphoid perilunate fracture-dislocation is presented, along with diagnosis, management and outcome.

INTRODUCTION: The scapholunate ligament is the most important stabilizer of the scapholunate articulation. The management of chronic irreversible injuries of this ligament in the absence of preexisting arthritis of the wrist joint remains controversial. Recently, surgeons introduced a novel surgical technique using an internal brace (IB). Several biomechanical studies on this technique have been conducted using cadavers; however, very few studies have discussed the results in detail in actual clinical practice. Therefore, herein, we investigated the radiological and functional results of patients who underwent IB augmentation as a treatment for chronic scapholunate dissociation. METHODS: This retrospective study was conducted from April 2018 to May 2022. Twenty-two patients with chronic scapholunate dissociation were treated using the IB augmentation technique, of whom 17 were followed-up for at least 1 year. Radiological results, including scapholunate distance, scapholunate angle, and radioscaphoid angle, were collected. Furthermore, clinical parameters, such as the visual analog scale (preoperative and at final follow-up), the Disabilities of the Arm, Shoulder, and Hand scores (preoperatively and at 3, 6, and 12 months postoperatively), and Mayo wrist scores (preoperative and at final follow-up), were measured. RESULTS: The scapholunate distance increased significantly in the affected wrist compared to the unaffected wrist, which improved after reconstruction in all wrist positions ( P < 0.05). Compared to the unaffected wrist, the scapholunate angle increased significantly in all positions ( P < 0.05) except for extension ( P = 0.535) and improved after reconstruction in all wrist positions. The radioscaphoid angle significantly increased compared to the angle of the unaffected wrist in all positions ( P < 0.05) except for extension ( P = 0.602) and clenched fist ( P = 0.556). This angle improved after reconstruction in all wrist positions except for extension ( P = 0.900). The visual analog scale score (7-2, preoperatively and at final follow-up) and Mayo wrist score (53-82, preoperatively and at final follow-up) improved after surgery. The Disabilities of the Arm, Shoulder, and Hand scores also improved after surgery (68, 53, 30, 7, preoperatively and at 3, 6, and 12 months postoperatively). CONCLUSIONS: This study revealed that scapholunate ligament reconstruction using an autologous tendon and suture tape is a good reconstruction technique that can improve clinical symptoms and radiographic parameters with a shorter operation time and fewer complications than other reconstruction methods.

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.

Isolated unilateral absence of lunate is an extremely rare condition with only one such case reported in English literature so far. The rarity of this condition can lead to diagnostic dilemma, especially if patient has an old history of trauma or surgery around the wrist, leading to unnecessary intervention and difficulty in ensuring a good surgical outcome. We present such a case and discuss the clinical pointers to the diagnosis of this condition. Level of Evidence: Level V (Therapeutic).

PURPOSE: To study the clinical, radiological, and functional outcomes after of radioscapholunate (RSL) fusion for intra-articular malunion of the distal radius. METHODS: This retrospective study included 26 patients (17 males and 9 females) with intra-articular malunion of distal radius fractures who underwent RSL arthrodesis using locked miniplates (without distal scaphoid excision) between 2012 and 2020. Their mean age was 43 years (range, 32-56). Patients were assessed radiographically for union and clinically for range of motion, grip strength, and pain (assessed by Visual Analogue Scale (VAS) for pain). Functional evaluation was performed by using the Mayo modified wrist score (MMWS) and the Disabilities for the Arm, Shoulder, and Hand (DASH) questionnaire. RESULTS: All patients showed complete healing at the fusion site after a mean of 8.7 weeks (range, 8-12). The mean follow-up period was 72 months (range, 60-84). The pinch strength improved from a mean of 6.2 kg (range, 3-12) to a mean of 9.8 kg (range, 5-18) which represents 80% of the contralateral side. The mean pinch strength was 7 kg (range, 5-18) which presents 80% of the other side. VAS for pain showed a mean improvement of 72.6%. The DASH score improved to a mean of 19.2 (range, 14-24). The MMWS improved to a mean of 68 (range, 45-86). At the final follow-up period, no degenerative changes were detected in the midcarpal joint. CONCLUSION: RSL arthrodesis (using locked miniplates without distal scaphoid excision) is a reliable surgical procedure to manage cases of radiocarpal OA after intra-articular malunion of distal radius fractures with good clinical and radiological outcomes. LEVEL OF EVIDENCE: Level IV- therapeutic.

OBJECTIVES: The relationship between volar fragment size and postoperative volar tilt loss in complete articular distal radius fracture is not well known. In this study, we measured precise radiological parameters to help identify other factors that might contribute to volar tilt loss. MATERIAL AND METHODS: We retrospectively reviewed the radiological examinations and charts of 256 patients with distal radial fracture who underwent volar locking plate fixation between March 2014 and July 2022. Radiological parameters were measured based on preoperative CT and immediate postoperative radiographs. Univariate and multivariate linear regression analysis was performed to identify relevant factors associated with volar tilt loss following volar locking plate fixation. The receiver operating characteristic curve was used to identify the cutoff value of the independent parameters. RESULTS: On univariate analysis, 2 radiologic parameters on preoperative CT (volar fragment length at the lunate fossa, and teardrop angle) and 4 on immediate postoperative X-ray (radial inclination, radial length, capitate shift, and volar tilt) were significantly associated with postoperative volar tilt loss. On multivariate linear regression analysis, the risk of volar tilt loss increased as the capitate moved toward the back of the radial shaft. The cut-off for anteroposterior length in the lunate fossa was 6.5 mm. CONCLUSIONS: AO/OTA type-C distal radius fractures with <6.5 mm anteroposterior length in the lunate fossa had significantly higher rates of malunion with dorsal deformity. In addition, preoperative teardrop angle <37.2 ° and immediate postoperative volar tilt <3.7º are also predictors of postoperative volar tilt loss.

PURPOSE: Although proximal row carpectomy (PRC) has increasingly been shown to have superior features to four-corner fusion (4CF), individual surgeons may remain convinced of the superiority of one procedure based on personal experience and individual biases. Hence, we sought to perform an updated meta-analysis with some of the largest studies to date to compare outcomes and complications between these procedures in the treatment of scapholunate advanced collapse and scaphoid nonunion advanced collapse wrists. METHODS: A systematic review and meta-analysis was performed per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed/MEDLINE, Embase, Web of Science, and Cochrane were queried for articles on PRC and 4CF performed for scapholunate advanced collapse and scaphoid nonunion advanced collapse wrist. Primary outcomes included wrist range of motion; grip strength; outcome measures, including Disabilities of Arm, Shoulder, and Hand and Quick Disabilities of Arm, Shoulder, and Hand scores, Patient-Rated Wrist and Hand Evaluation, and visual analog scale pain scores; and surgical complications. RESULTS: Sixty-one studies reported on 3,174 wrists, of which 54% were treated with PRC and 46% were treated with 4CF. The weighted mean follow-up was 61 months (range, 12-216 months). Meta-analysis comparing PRC and 4CF demonstrated that PRC had significantly greater postoperative extension; ulnar deviation; postoperative improvement in extension, flexion, ulnar deviation; and visual analog scale score. No comparisons showed significant differences in grip strength. The percentage of wrists requiring arthrodesis was 5.2% for PRC and 11% for 4CF. There was an 8.9% (57/640 wrists) 4CF nonunion rate and 2.2% (17/789) hardware removal rate after 4CF. CONCLUSIONS: In the treatment of scapholunate advanced collapse and scaphoid nonunion advanced collapse wrists, PRC results in better outcomes and a lower complication rate compared to 4CF. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: Anatomical front and back (ANAFAB) reconstruction addresses the critical volar and dorsal ligaments associated with scapholunate dissociation. We hypothesized that patients with symptomatic, chronic, late-stage scapholunate dissociation would demonstrate improvements in all radiographic parameters and patient-reported outcomes (PROMs) after ANAFAB reconstruction. METHODS: From 2018 to 2021, 21 ANAFAB reconstructions performed by a single surgeon were followed prospectively, with 20 patients having a minimum follow-up of 12 months. In total, 17 men and four women were included, with an average age of 49 years. Three patients had modified Garcia-Elias stage 3 disease, eight stage 4, seven stage 5, and three stage 7. ANAFAB reconstruction of intrinsic and extrinsic ligament stabilizers was performed using a hybrid synthetic tape/tendon graft in a transosseous reconstruction. Pre- and postoperative radiographic parameters, grip, pinch strength, the Patient-Rated Wrist Evaluation, PROMIS Upper Extremity Function, and PROMIS Pain Interference outcome measures were compared. RESULTS: Mean follow-up was 17.9 months (range: 12-38). Radiographic parameters were improved at follow-up, including the following: scapholunate angle (mean 75.3° preoperatively to 69.2°), scapholunate gap (5.9-4.2 mm), dorsal scaphoid translation (1.2-0.2 mm), and radiolunate angle (13.5° to 1.8°). Mean Patient-Rated Wrist Evaluation scores for pain and function decreased from 40.6 before surgery to 10.4. We were unable to detect a significant difference in grip or pinch strength or radioscaphoid angle with the numbers tested. There were two minor complications, and two complications required re-operations, one patient who was converted to a proximal row carpectomy for failure of fixation, and one who required tenolysis/arthrolysis for arthrofibrosis. CONCLUSIONS: At 17.9-month average follow-up, radiographic and patient-reported outcome parameters improved after reconstruction of the critical dorsal and volar ligament stabilizers of the proximal carpal row with the ANAFAB technique. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Injury to the scapholunate complex is the cause of scapholunate instability which can lead to radiocarpal and medio-carpal osteoarthritis. Several ligamentoplasty techniques have been reported for the treatment of chronic scapholunate instability before the osteoarthritis stage. The objective of this study was to assess the short-term results of an "all dorsal scapholunate repair" ligamentoplasty. We report the clinical, radiological and functional results of a retrospective study including 21 patients, operated between June 2019 and December 2020 for a stage 3 or 4 scapholunate instability according to the Garcia Elias classification. With a follow-up of 14.2 months, the pain was 0.1/10 according to the VAS at rest and 4/10 during exercise. Wrist strength was measured at 65% of the opposite side. The flexion-extension range of motion was 105°. Radiologically, there was a reduction of the diastasis and scapholunate angle. Osteolysis areas around the anchors were described in 47% of patients. The mean QuickDASH was 29.2/100, PRWE 24/100 and Mayo wrist score 67.8/100. Eighty-one percent of patients were satisfied. Seventeen patients had returned to work 5.2 months postoperatively. In the case of work-related injury, the functional scores were poorer, with a delayed return to work. This technique provides encouraging results in the short term. Most patients were improved compared to preoperative state. The work-related injury appears to be a poor prognostic factor. A longer-term study is imperative to confirm the maintenance over time of the correction of carpal malalignment and the evolution of the osteolysis areas.Level of evidence: Level IV Retrospective study.

Multiple techniques exist to reconstruct the scapholunate interosseous ligament, though none have demonstrated superiority. This study compares 1-year radiographic outcomes of the three-ligament tenodesis and the anatomical front and back reconstruction. All patients who underwent reconstruction of their scapholunate interosseous ligament at one institution with either anatomical front and back reconstruction or three-ligament tenodesis between 2011 and 2020 were retrospectively reviewed. At 52-week follow-up, anatomical front and back reconstruction maintained a statistically significant improvement in scapholunate gap, corrected radiolunate angle and dorsal scaphoid translation, while three-ligament tenodesis demonstrated no sustained improvement in any parameter. The improvement in dorsal scaphoid translation was significantly greater for patients undergoing anatomical front and back reconstruction compared with three-ligament tenodesis at the 16-weeks postoperative timepoint (-1.0 mm, -0.3 mm). Anatomical front and back reconstruction demonstrates sustained improvement in radiographic outcomes at 1 year when compared with three-ligament tenodesis. By addressing both volar and dorsal critical ligament restraints, adoption of anatomical front and back reconstruction for advanced stage scapholunate interosseous ligament injuries should be considered.Level of evidence: IV.

OBJECTIVE: Scapholunate instability is the most common ligament injury of the wrist. In case of predynamic instability, diagnosis can be difficult, even under arthroscopy. Scapholunate instability is not the result of an isolated injury to the scapholunate interosseous ligament. Scapholunate stability is dependent not only on the scapholunate ligament, but on a complex that is comprising intrinsic and extrinsic ligaments. The dorsal capsule-scapholunate septum (DCSS) is one of the secondary stabilizers of the scapholunate complex. The objective of the present study was to investigate the correlation between DCSS lesion and predynamic scapholunate instability. METHOD: A prospective multicenter study included patients who underwent wrist arthroscopy for traumatic wrist. Arthroscopic DCSS lesion stage and instability according to European Wrist Arthroscopy Society stage were assessed. RESULTS: Twenty-seven subjects were included. We found a significant correlation between pathological DCSS and predynamic scapholunate instability and a correlation between DCSS lesion severity and instability level. CONCLUSION: Isolated DCSS lesion should be considered a predictive factor for predynamic instability.

INTRODUCTION: The optimal treatment of chronic scapholunate instability has yet to be established. Scapholunate ligament grafts are still far from being the ideal solution. We conducted an experimental study to evaluate whether flexion-opening wedge osteotomy of the distal radius improves misalignment and avoids rotatory subluxation of the scaphoid in a cadaveric model of static scapholunate dissociative instability. MATERIALS AND METHODS: Radiographic studies were performed on 15 cryopreserved specimens after recreating a model of scapholunate instability by division of the scapholunate interosseous ligament (SLIL) and secondary stabilizers, taking radiographs at baseline, after the instability model, and after distal radius osteotomy. Static and dynamic (under controlled tendon traction) anteroposterior and lateral views were obtained to measure the length (in mm) of the carpal scaphoid and scapholunate interval, scapholunate angle, radio-lunate angle, and palmar tilt of the distal joint surface of the radius and to measure the dorsal scaphoid translation by the concentric circles method. The Wilcoxon test was used for statistical comparisons. RESULTS: The scapholunate interval was significantly decreased after osteotomy in all static anteroposterior views and in all lateral views under tendon traction. Dorsal scaphoid translation was significantly reduced in static lateral view in extension and in dynamic lateral view under 5-pound flexor carpi radialis tendon tension controlled by a digital dynamometer. CONCLUSIONS: Flexion-addition osteotomy of the distal radius appears to improve carpal alignment parameters in a cadaveric model of static scapholunate instability, achieving similar values to those obtained before instability.

CASE: Augmented scapholunate ligament reconstruction using polyether ether ketone anchors and ultra-high molecular weight polyethylene synthetic tape has the theoretical advantage of improved stability, avoidance of K-wire fixation, and the potential for earlier mobilization. We present 3 cases of scaphoid and lunate osteolysis/fragmentation, operative and histologic findings at reoperation, and the sequelae of this technique. CONCLUSION: If planning to use suture anchors and synthetic tapes in small carpal bones, we recommend advising patients about the risk of osteolysis and monitoring closely patients who complain of pain with motion after surgery.

Semilunate and perilunate dislocation is an injury that mostly occurs when the subject is exposed to a high-energy trauma. Considered severe, it compromises the stability and function of the wrist. The case presented is that of a 50-year-old male patient who after having a motorcycle accident arrived at the ER with neurovascular affectation, swelling, deformity and a considerable decrease of the wrist joint movement. He was also referring severe pain. A Henry (Volar) intervention was done with the help of external fixation of the lunate, followed by K-wire fixation, once a prior closed reduction was unsuccessfully attempted. The scaphoid was connected to the semilunate, and then the latter with the capitate. Ligament reconstruction followed, and stability was clinically confirmed with an X-ray. Although improvement of symptomatology was observed during the follow-up analysis, motion of the wrist remained limited. Even with the best treatment, in terms of functionality, this type of injury presents a poor prognosis.
La luxación semilunar y perilunar es una lesión que se produce principalmente cuando el sujeto está expuesto a un traumatismo de alta energía. Considerada grave, compromete la estabilidad y la función de la muñeca. El caso presentado es el de un paciente varón de 50 años que tras sufrir un accidente de motocicleta llegó a urgencias con afectación neurovascular, tumefacción, deformidad y una considerable disminución del movimiento articular de la muñeca. También refería fuertes dolores. Se realizó una intervención de Henry (Volar) con la ayuda de fijación externa del lunar, seguida de fijación con agujas de Kirschner, una vez que se había intentado sin éxito una reducción cerrada previa. El escafoides se conectó con el semilunar y luego éste con el capitado. A continuación se reconstruyó el ligamento y se confirmó clínicamente la estabilidad con una radiografía. Aunque se observó una mejora de la sintomatología durante el análisis de seguimiento, el movimiento de la muñeca seguía siendo limitado. Incluso con el mejor tratamiento, en términos de funcionalidad, este tipo de lesión presenta un mal pronóstico.

OBJECTIVE: To explore clinical efficacy of dorsal plate assisted fixation of dorsal lunate fossa fracture block of distal radius. METHODS: From January 2019 to January 2022, 30 patients were treated with dorsal plate assisted fixation of dorsal lunate fossa fracture of distal radius, including 13 males and 17 females, aged from 42 to 68 years old with an average of (48.7±5.6) years old;According to Doi fracture classification, 24 patients were type 3 blocks and 6 patients were type 4 blocks. The degree of palmar angle of anterior and posterior distal radius was fixed by dorsal steel plate during operation. Fracture healing and functional recovery of wrist were observed after operation. Functional evaluation was performed by Gartland and Werley scoring system at 12 months after operation. RESULTS: All patients were followed up from 12 to 13 months with an average of (11.3±0.9) months. All fractures healed for 4 to 5 months with an average of(4.7±0.8) months. Median palpal inclination of anterior and posterior distal radius fixed by dorsal plate was 5.30°(4.85°, 6.03°), 12.45°(11.98°, 13.43°) respectively, and had statistical difference( P<0.01). Gartland and Werley scores was (1.1±0.4) at 12 months afteropertaion, and 27 patients got excellent result and 3 good. CONCLUSION: Dorsal plate assisted fixation of dorsal lunate fossa fractures is beneficial to reduction and stabilization of displaced dorsal fractures and restoration of palmar inclination.
