[PMID: 39054230 DOI: 10.1016/j.jos.2024.07.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 05/28/2024] [Accepted: 07/07/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND This study aimed to introduce a potential alternative percutaneous treatment for AO types C1, C2, and C3 distal radius fractures using dual-external fixator (a no-bridging cemented-pin frame and a conventional wrist-bridging external fixator). MATERIALS AND METHODS From January 2018 to January 2021, 52 patients (52 distal radius fractures) were treated with dual-external fixator. For comparison, 61 patients (61 distal radius fractures) were treated with a plate and screw system. Wrist function was assessed using the Mayo Wrist Score. Patient satisfaction was assessed using the Short Assessment of Patient Satisfaction. A P < 0.05 was considered statistically significant. RESULTS Fracture healing was achieved in all patients. At the final follow-up of 29 months (range, 24-34 months) vs 36 months (range, 26-39 months) (P > 0.05), the patients treated with dual-external fixator and a plate and screw system achieved mean ulnar deviations of 31° vs 29° (P < 0.05), mean Mayo Wrist Scores of 91.12 ± 5.98 vs 88.12 ± 7.54 (P < 0.05), and mean patient satisfaction scores of 23.42 ± 2.47 vs 23.04 ± 2.32 (P > 0.05). CONCLUSIONS AO types C1, C2, and C3 distal radius fractures can be treated successfully using dual-external fixator. The technique is a potential alternative in addition to the conventional treatments. LEVEL OF EVIDENCE Level IIa.

Abstract
Background: The anatomical reconstruction of the wrist is the aim when treating distal radius fractures. Current literature on the importance of preoperative reduction in fractures that are treated operatively is limited. Methods: This study investigated the effect of the preoperative closed reduction of distal radius fractures on the day of trauma and the time to surgery on postoperative palmar inclination. A total of eighty patients (48 females and 32 males, mean age 55.6 years) were studied retrospectively. All patients were treated with an open reduction and internal fixation. The palmar inclination angle was measured using X-rays by two investigators, and the interobservers and pre- and post-reduction parameters were compared. Results: When the surgical management of closed distal radius fractures is required, neither initial repositioning nor a delay of up to 14 days to the surgical treatment influences postoperative palmar inclination. Conclusions: The significance of preoperative reduction of distal radius fractures without neurovascular or extensive soft tissue damage is limited and is not leading to improved outcomes. When surgery is about to be performed, surgeons should carefully consider if reduction is really vital preoperatively. Level of evidence: III.

Abstract
OBJECTIVE Distal fracture of the radius is common in all age groups. Under careful consideration of individual indications and contraindications, conservative treatment with reduction and immobilization can have significant advantages over the frequently applied surgical approach, particularly in older patients. THERAPEUTIC GOAL Immobilization after closed reduction enables satisfactory wrist function to be achieved according to individual patient expectations. INDICATIONS A. Patients with a. significant comorbidities, b. high surgical risk from an anesthesiology perspective (ASA > 3), c. low functional requirements, d. low cosmetic expectations regarding residual visible deformity. B. Young patients with an extension fracture and additional a. < 10° dorsal tilt in the case of extraarticular fractures after closed reduction, b. < 5 mm radial shortening after closed reduction, c. < 2 mm intraarticular displacement after closed reduction. CONTRAINDICATIONS A. Patient age < 65 years with an extension fracture and additional a. > 10° dorsal tilt in the case of extraarticular fractures after closed reduction, b. > 5 mm radial shortening after closed reduction, c. > 2 mm intraarticular displacement after closed reduction. B. Flexion fracture for which ligamentotaxis for closed reduction is not possible. C. Open distal radial fracture. D. Fracture dislocations. E. Impairments of peripheral circulation, motor or sensory function of the hand after reduction. TECHNIQUE After puncturing the fracture hematoma and infiltrating the fracture gap with local anesthetic, the forearm is suspended using Chinese finger traps on the thumb and middle finger. Constant traction in the longitudinal axis of the forearm is ensured by a weight applied via a wide cushioned cuff to the distal upper arm. Reduction then is enabled with the additional reductive effect of ligamentotaxis. After minimal cushioning of the forearm with cotton wool and crepe bandage, a dorsal gypsum longuette is applied. After the plaster bandage has hardened, peripheral circulation, motor function, and sensitivity are checked. The reduction is controlled by X‑ray and documented. POSTPROCEDURAL MANAGEMENT A. General procedures to reduce swelling; sufficient analgesics should be prescribed. B. The circular plaster cast is applied once swelling has subsided sufficiently, generally after 2-3 days. C. The duration of cast wearing should be planned at 5 weeks. RESULTS A total of 73 patients (55 women and 18 men) aged 65-88 years were followed up for 12 months to investigate functional outcomes after surgical and conservative therapy. While surgical patients had better functional scores up to 12 weeks after treatment begin, there was no longer a significant difference in the 6‑ and 12-month follow-up results. The measured grip strength was consistently better in the surgically treated group. Clinically visible deformities were present in 78% of the conservatively treated patients; however, the patients were satisfied with the functional or cosmetic results. No deformities were seen in the surgically treated patients. All fractures were completely healed after 6 months. The rate of complications was significantly higher in the surgery group, with 13 complications compared to 5 in the conservative treatment group.

Arch Orthop Trauma Surg 2023:10.1007/s00402-023-04904-z. [PMID: 37178164 DOI: 10.1007/s00402-023-04904-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 04/30/2023] [Indexed: 05/15/2023]
Abstract
INTRODUCTION A repeated closed reduction ("re-reduction") of a displaced distal radius fracture is a common procedure performed to obtain satisfactory alignment and avoid surgery when the initial reduction is deemed unsatisfactory. However, the efficacy of re-reduction is unclear. Compared to a single closed reduction, does a re-reduction of a displaced distal radius fracture: (1) improve radiographic alignment at the time of fracture union and, (2) decrease the rate of operative intervention? MATERIALS AND METHODS Retrospective cohort analysis of 99 adults aged 20-99 years with extra-articular or minimally displaced intra-articular, dorsally angulated, displaced distal radius fracture with or without an associated ulnar styloid fracture who underwent a re-reduction, compared against 99 adults matched for age and sex who were managed with a single reduction. Exclusion criteria were skeletal immaturity, fracture-dislocation and articular displacement greater than 2 mm. Outcome measures included radiographic alignment at fracture union and rate of surgical intervention. RESULTS At 6-8 weeks follow-up, the single reduction group had greater radial height (p = 0.045, CI 0.04 to 3.57), and less ulnar variance (p < 0.001, CI - 3.08 to - 1.00) compared to the re-reduction group. Immediately following re-reduction, 49.5% of patients met radiographic non-operative criteria, but by 6-8 weeks follow-up, only 17.5% of patients continued to meet these criteria. Patients in the re-reduction group were treated with surgery 34.3% of the time, compared to 14.1% of the time for patients in the single reduction group (p = 0.001). In patients aged under 65 years, 49.0% of those who underwent a re-reduction were managed with surgery, compared to 21.0% of those who had a single reduction (p = 0.004). CONCLUSION A re-reduction performed to improve radiographic alignment and avoid surgical management in this subset of distal radius fractures had minimal value. Alternative treatment options should be considered before attempting a re-reduction.

Abstract
PURPOSE It remains unclear whether time-to-surgery for distal radius fractures affects clinical, functional, or radiographic outcomes or health care costs/use. This systematic review investigated the outcomes of early versus delayed surgery for closed, isolated distal radius fractures in adult patients. METHODS A comprehensive search of MEDLINE, Embase, and CINAHL databases was completed for all original case series, observational studies, and randomized controlled trials reporting clinical outcomes of both early and delayed surgically-treated distal radius fractures from database inception to July 01, 2022. A consistent threshold of two weeks was used to define early versus delayed treatment arms. RESULTS Nine studies, including 16 intervention arms and 1,189 patients (858 early, 331 delayed), were included. Mean age was 58 years (range, 33-76). At more than one year, the frequency-weighted mean Disabilities of the Arm, Shoulder, and Hand score was 4 in the early group (n = 208; range, 1-17) and 21 in the delayed group (n = 181; range, 4-27). Range of motion, grip strength, and radiographic outcomes were comparable. The pooled mean complication rate (7% vs 5%) and revision rate (3.6% vs 1%) were very low in both groups. CONCLUSIONS A delay in time-to-surgery greater than two weeks for distal radius fractures may be associated with inferior patient-reported outcomes. Early surgery was associated with improved long-term Disabilities of the Arm, Shoulder, and Hand scores. On the basis of the available evidence, range of motion, grip strength, and radiographic outcomes are similar. The complication and revision rates were very low in both groups and comparable.

Abstract
Today, there are various classifications for distal radius fractures (DRF). However, they are primarily based on plain radiographs and do not provide sufficient information on the best treatment option. There are newer classifications that simultaneously consider the pathobiomechanical basis of the fracture mechanism and analysis of computed tomography images. Main determinants of which type of DRFs occurs are the strength/direction of the applied forces on the carpus and radius, and the position of the wrist relative to the radius during the fall. Reconstruction of the mechanism of injury provides information about which anatomic structures are involved, such as torn ligaments, bone fragments, and the dislocated osteoligamentous units. This article attempts to combine and modify current pathobiomechanically oriented classifications with an improved understanding of the "key fragments" to subsequently offer a treatment approach to stabilize these critical fragments through specific types of internal fixation.

Abstract
INTRODUCTION Distal radius fractures are common orthopedic injuries managed in emergency departments. Simulation-based mastery learning is widely recognized to improve provider competence for bedside procedures but has not been studied to teach fracture management. This study evaluated the effectiveness of a simulation-based mastery learning curriculum to teach distal radius fracture reduction to novice orthopedic surgery and emergency medicine residents. METHODS We created a novel mastery learning checklist using the Mastery Angoff method of standard setting, paired with a new simulation model designed for this project, to teach orthopedic surgery and emergency medicine interns (N = 22) at the study site. Orthopedic surgery and emergency medicine faculty members participated in checklist development, curriculum design, and implementation. Training included just-in-time asynchronous education with a readiness assessment test, in-classroom expert demonstration, and deliberate practice with feedback. Residents completed a pretest/posttest skills examination and a presurvey/postsurvey assessing procedural confidence. RESULTS Standard setting resulted in a 41-item checklist with minimum passing score of 37/41 items. All participants met or surpassed the minimum passing score on postexamination. Postsurvey confidence levels were significantly higher than presurvey in all aspects of the distal radius fracture procedure (P < 0.05). CONCLUSIONS This study demonstrated that a simulation-based mastery learning curriculum improved skills and confidence performing distal radius fracture reductions for orthopedic surgery and emergency medicine interns. Future planned studies include curriculum testing across additional institutions, examination of clinical impact, and application of mastery learning for other orthopedic procedures.

Abstract
Distal Radius fractures (DRF) are one of the most common injuries in the upper extremity and incidence is expected to rise due to a growing elderly population. The complex decision to treat patients operatively or conservatively depends on a large variety of parameters which have to be considered. No unanimous consensus has been reached yet, which operative approach and fixation technique would produce the best postoperative functional results with lowest complication rates. This article addresses the available evidence for indications, approaches, reduction, and fixation techniques in treating DRF.

Abstract
Indications for surgical treatment of distal radius fractures (DRF) remain controversial in the literature, especially in elderly patients. Complication rates after operatively treated DRF are low and well documented. These include malunion, degenerative osteoarthritis in the radiocarpal joint and subsequently pain and impaired hand function. If conservative treatment fails then salvage procedures are necessary. This review summarizes the therapeutic options available to treat degenerative osteoarthritis after malunited distal radius fractures, regardless of the initial operative or conservative treatment.

Abstract
In the recent years, treatment of distal radius fractures (DRF) has advanced considerably. Surgical fixation with palmar angular stable plate has gained popularity, due to a reported lower complication rate when compared to dorsal fixation. The type of trauma or injury, surgical procedure and impaired bone quality are all contributors to complications in DRF. The main aim of this review is to summarize the most common complications and possible therapeutic solutions. In addition, strategies for minimizing these complications will be discussed.

Abstract
Although the literature generally agrees that displaced distal radius fractures require surgery, no single consensus exists concerning the length of immobilization and type of post-operative physiotherapeutic rehabilitation program. Palmar locking plate fixation represents a very stable fixation of the distal radius, and was assessed biomechanically in various studies. Surprisingly, most authors report additional immobilization after plate fixation. One reason might be due to the pain caused during active wrist mobilization in the early post-operative stages or secondly to protect the osteosynthesis in the early healing stages preventing secondary loss of reduction. This article addresses the biomechanical principles, current available evidence for early mobilization/immobilization and impact of physiotherapy after operatively treated distal radius fractures.

Biomechanical considerations on a CT-based treatment-oriented classification in radius fractures. Arch Orthop Trauma Surg 2020; 140:595-609.

Abstract
A wide range of different classifications exist for distal radius fractures (DRF). Most of them are based on plane X-rays and do not give us any information on how to treat these fractures. A biomechanical understanding of the mechanical forces underlying each fracture type is important to treat each injury specifically and ensure the optimal choice for stabilization. The main cause of DRFs are forces acting on the carpus and the radius as well as the position of the wrist in relation to the radius. Reconstructing the mechanism of the injury gives insight into which structures are involved, such as ruptured ligaments, bone fragments as well as the dislocated osteoligamentous units. This article attempts to define certain key fragments, which seem crucial to reduce and stabilize each type of DRF. Once the definition is established, an ideal implant can be selected to sufficiently maintain reduction of these key fragments. Additionally, the perfect approach is selected. By applying the following principles, the surgeon may be assisted in choosing the ideal form of treatment approach and implant selection.

Ulnar shortening osteotomy as a treatment of symptomatic ulnar impaction syndrome after malunited distal radius fractures. Arch Orthop Trauma Surg 2020; 140:681-695. [PMID: 32193682 DOI: 10.1007/s00402-020-03374-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Indexed: 02/09/2023]
Abstract
A malunited distal radius fracture can lead to symptomatic ulnar impaction syndrome, which is a common cause for ulnar-sided wrist pain. If conservative treatment fails and symptoms persist after an arthroscopic ulnocarpal debridement, ulnar shortening osteotomy (USO) is the treatment of choice. Since the first USO described by Milch in 1941 after a malunited Colles fracture, many techniques have been described varying in surgical approach, type of osteotomy and osteosynthesis material used. Many studies demonstrated good to very good functional results after USO, reporting, however, a delayed union or non-union rate up to 18%. A modern, low profile, locking plate showed in our short-term study very good functional results and no implant-associated complications, in particular no non-union.

Abstract
OBJECTIVE Radioscapholunate (RSL) arthrodesis with distal scaphoidectomy using an angular stable plate and palmar access in post-traumatic or degenerative osteoarthritis limited to the radiocarpal joint. INDICATIONS Osteoarthritis limited to the radiocarpal joint with intact mediocarpal joint after malunited intra-articular distal radius fractures, rheumatoid osteoarthritis, scapholunate advanced collapse (SLAC) up to stage II. CONTRAINDICATIONS Mediocarpal osteoarthritis, poor patient compliance, SLAC from stage III, osteitis. SURGICAL TECHNIQUE The palmar RSL arthrodesis is performed using the palmar approach between the flexor carpi radialis tendon and the radial artery. After releasing the pronator quadratus muscle, a longitudinal capsulotomy is performed and the radiocarpal joint is inspected. After correction of a volar or dorsal intercalated segmental instability of the lunate, the lunate is temporarily fixed to the scaphoid using a K-wire. The distal quarter of the scaphoid and the palmar rim of the distal radius is resected and the cartilage between the scaphoid, lunate and distal radius is removed. The scaphoid and lunate are temporarily fixed to the distal radius using K‑wires. Under image intensifier control the angular stable low-profile plate (e.g., volar 2.5 Trilock RSL Fusion plate [Medartis® Aptus® Basel, Switzerland]) is fixed to the distal radius in the long-leg hole. The scaphoid and lunate are fixed distally with two screws each. The carpus is pushed distally using a Codeman distractor and the cancellous bone graft is impacted. Finally, the shaft is fixed with angular stable screws. POSTOPERATIVE MANAGEMENT Immobilization using a plaster cast or thermoplastic short-arm orthosis for 5 weeks. After 2 weeks, the orthosis can be removed during hand therapy with active wrist and finger exercises. Normal activities permitted after 12 weeks. RESULTS Palmar RSL arthrodesis and distal scaphoidectomy using angular stable plate fixation shows a high union rate and pain relief while maintaining good residual mobility of the wrist.

Abstract
PURPOSE The purpose of this study was to demonstrate the necessity of achieving acceptable radiographic alignment by preoperative closed reduction in unstable distal radius fractures (DRFs) to improve preoperative pain and obtain satisfactory outcomes after surgery. METHODS From 2013 to 2016, patients who received volar locking plates for DRFs were retrospectively reviewed. Patients were classified into acceptable and non-acceptable reduction groups based on immediate post-reduction radiographs. To avoid potential bias, a matched-pair analysis was performed, and paired patients were categorized into non-acceptable reduction (group A) and acceptable reduction (group B) groups. Preoperative pain level, mean length of stay, operation time, postoperative complications, and surgical outcomes were analysed. The preoperative pain level and functional results were assessed by the visual analogue scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores. RESULTS Of the 239 patients, 80 had non-acceptable and 159 had acceptable reductions. Among these patients, 201 (66 in group A vs. 135 in group B) were matched in a 1:2 matched ratio. Although the radiological parameters after closed reduction were better in group B, there were no significant differences in the preoperative pain VAS score, mean length of stay, operation time, and postoperative complications between the groups. In addition, radiologic parameters and the DASH score at a 1-year follow-up were also not significantly different between the groups. CONCLUSION Our results suggest that obtaining acceptable radiologic alignment by closed reduction is not necessary for patients who make an informed decision to undergo volar plating for unstable DRFs.

Abstract
Background The aim of this study was to evaluate the influence of distal radius fractures (DRFs) malalignment on the treatment outcomes in patients over age 65 years. Material/Methods We retrospectively reviewed the records on fresh DRFs treated with closed reduction from December 2014 to January 2018. After treatment, patients were evaluated for the determination of grip strength, the Visual Analog Scale (VAS) during wrist movement, the Patient-Rated Wrist Evaluation (PRWE), the Disabilities of the Arm, Shoulder and Hand (DASH) score, the appearance satisfaction, and active wrist range of motion (ROM). Results A total of 96 patients with complete data were included in our study. During follow-up, there were 75 patients (78.1%) with acceptable reduction and 21 patients (21.9%) with unacceptable reduction. Compared with those having acceptable alignment in the distal radius, patients with unacceptable alignment had weak grip strength, were unsatisfied appearance, and had severe flexion as well as ulnar deviation limitation at 6-month follow-up. A significant correlation was found between ulnar positive variance and grip strength (r=−0.35, P=0.03), as well as dorsal angulation and flexion movement (r=−0.31, P=0.02). Conclusions Conservative treatment should be used differently, even in elderly patients. For low-demand patients, it is not necessary to restore all anatomic radiographic parameters, as malalignment does not increase disability or pain score. However, for patients who are still healthy and active, satisfactory reduction is the first choice, as malalignment can lead to decreased grip strength, dissatisfaction with appearance, and certain wrist limitations.

Abstract
OBJECTIVE Primarily to determine mid-term functional outcome for patients with distal radius fracture (DRF) and to compare this between operative and conservatively managed patients. Secondarily to examine for differences in age, gender and number of instability factors between management groups. METHODS Eligible patients (age 18 years or more, closed DRF managed to completion of care within Monash Health), presenting between 1 January and 31 December 2016. Completion of the patient-rated wrist evaluation (PRWE) questionnaire was sought at 6-12 months post-injury. Management was noted (operative or conservative). Age, sex and number of defined instability factors present (dorsal angulation >20°, intra-articular fracture, associated ulna fracture, dorsal comminution, radial shortening >2 mm) are reported and compared between management groups. RESULTS Of 369 eligible patients, 199 (54%) completed a PRWE. Median age was 60 years (interquartile range [IQR] 45-71), 150 (75%) were women, median number of instability factors present was 2 (IQR 1-4) and 45 (23%) underwent operative management. Difference in PRWE scores between operative and conservatively managed patients was not significant (20 [IQR 7-36] vs 16 [IQR 5-35]). Differences in age and gender between management groups were not significant. Significantly more in the operative group had presence of four or more instability factors (44% [95% confidence interval 30-60] vs 20% [14-27]). CONCLUSION The mid-term median PRWE score was 18 (IQR 5-36). This was not significantly different between operative and conservatively managed patients. Operation was more likely when four or more instability factors were present.

Three-dimensional kinematics of the flexor pollicis longus tendon in relation to the position of the FPL plate and distal radius width. Arch Orthop Trauma Surg 2019; 139:269-279.

Abstract
INTRODUCTION The standard therapy of intra-articular and extra-articular distal radius fractures consists of open reduction and stabilization using palmar osteosynthesis with an angularly stable plate. The integrity of the flexor pollicis longus tendon (FPLT) may be mechanically affected by the plate, with rupture rates between 1 and 12% reported in the literature, occurring during a postoperative time period from 4 to 120 months. The aim of this study was to investigate the position of the tendon in relation to the distal edge of the plate using high-resolution ultrasonic imaging. MATERIALS AND METHODS Nineteen patients undergoing osteosynthesis for distal radius fracture in 2015 with the Medartis® APTUS® FPL plate were included in this study. Of these, seven dropped out for various reasons. Therefore, twelve patients with a median age of 52 years (range 24-82 years) were included in the final analysis. High-frequency ultrasound was performed within a median of 28 (range 10-52) weeks by an experienced radiology specialist to locate the FPLT position in two separate wrist positions: (1) wrist held in 0° position and fingers extended and (2) wrist held in 45° of dorsal extension and actively flexed fingers II to V (functional position). For analysis, we used the axial ultrasound videos. Postoperative X-rays and CT scans were included for the analysis, especially the soft-tissue CT scan window for the exact localization of the FPLT. Dynamic ultrasound scanning was used to localize the FPLT in relation to the plate in 0° and functional position of the hand. Using CT scanning, the position of the plate relative to the bone was determined. In this way, we were able to correlate the functional FPLT position with the osseous structures of the distal radius. RESULTS In all cases, the FPLT was positioned closer to the volar distal edge of the FPL plate in functional position than in 0° position. In four cases, the FPLT did not touch the plate at all and was shown to shift diagonally from radio-volar in ulno-dorsal direction during wrist movement from 0° to functional position, similarly to the sliding of the tendon in the assumed physiological motion sequence. In these cases, in the functional position the center of the FPLT was positioned slightly ulnarly of the center of the distal radius (i.e., less than 50% of the distal radius width measured from the radial border of DRUJ), and positioned more ulnarly than in all other cases (i.e., in which the FPLT came into contact with the plate). In the remaining two-thirds of the cases (eight patients), the FPLT touched the plate during wrist movement from 0° to functional position, shifted in dorsal direction and slid into the plate indentation, irrespective of whether the tendon entered the indentation from the radial or the ulnar side, and independent of the ulnoradial position of the plate. No signs of tendinopathy of the FPLT were found in any of the cases. CONCLUSION The results show that the indentation of the Medartis® APTUS® FPL plate reduces the tendon-plate contact and ideally even prevents it entirely. In particular, ulnar positioning of the plate lowers the risk of tendon-plate contact. If the FPLT touches the plate, the tendon pulls into the plate indentation, thus lowering the contact. Consequently, the Soong criteria are not applicable when a FPL plate is used.

Abstract
INTRODUCTION Distal radius fractures (DRF) are the most common fractures of the upper extremities. The incidence is expected to continue rising in the next years due to the increased life expectancy. Palmar locking plate stabilizing has since become the standard treatment for dorsally displaced DRF with a complication rate of 8-39% reported in the literature. Main aim of this study was to investigate the incidence of complications after DRF stabilization using palmar angular stable locking plate. METHODS A retrospective medical records review conducted from January 2013 to December 2016 included a total of 392 patients with DRF, that were stabilized using palmar angular stable locking plate and showed a minimum follow-up of 3 months. The group comprised 259 female and 133 male patients with a mean follow-up interval of 11 months (range 3-52 months). All recorded complications were documented. Range of motion (ROM) in extension, flexion, supination, pronation, radial- and ulnar deviation of the last follow-up was noted. Age was divided into younger than 65 years (< 65 years) and older than 65 years (≥ 65 years). The primary, immediate postoperative and final checkup radiographs were scrutinized for alignment and intra-articular step-off. RESULTS A total of 51 (13%) early and 17 late (4%) complications were recorded in 392 patients. The most common complications included carpal tunnel syndrome (3%), complex regional pain syndrome (3%) and loss of reduction (2%). Of the 68 complications, only 25 (6%) were directly related to the plate. 73% of all complications occurred in AO type C fractures. Patients without complications showed a significantly better ROM in extension, flexion, pronation and supination than patients with complications. No significant differences in incidence of complications, ROM or loss of reduction could be found between patients over and under 65 years of age. Gender and type of immobilization showed no significant influence on the complication rate. CONCLUSIONS Stabilization of DRF by palmar angular stable locking plate is a safe form of treatment. In the majority of the cases a good clinical and radiological outcome with no complications was documented. Gender and type of immobilization had no impact on the complication rate and an age over 65 years is not associated with an increased risk for complications or restricted ROM.
