We presumed that primary repair would be possible if the extensor pollicis longus (EPL) rupture after volar locking plating (VLP) for distal radius fracture (DRF) was diagnosed earlier. Thus, five cases of EPL ruptures were resolved via primary repair rather than extensor indicis proprius (EIP) transfer, so we reported the clinical outcomes of at least 2 years follow-up since EPL repair. Of 588 consecutive patients with the fractures treated between January 2016 and December 2019, 501 who met out inclusion/exclusion criteria were initially investigated. We informed patients of: (1) the ordinary range of motion of thumb at full wrist flexion/extension; (2) the proper tone of thumb extension compared to the contralateral thumb; and (3) the degree of pain/discomfort during thumb exercise. After discharge, we called each patient monthly commencing at 8 weeks postoperatively to enquire if any of those had worsened, by telephone. Five patients had ruptured EPLs diagnosed at a mean of postoperative-12.8 weeks. Three came to outpatient department for suspected tendon rupture just after telephone survey with the authors. The other two visited after detecting insufficiency in the three items, during the period between telephone inquiries. In four, the torn EPL were encapsulated by tendon sheathes. Extension lag at interphalangeal joint was absent and other clinical outcomes associated with DRF were all satisfactory at final follow-up. Primary repair of EPL rupture (rather than EIP transfer) is possible if patients are properly followed up after VLP for DRF. LEVEL OF EVIDENCE: Level IV, retrospective case series.

This study aimed to assess the influence of the surgeon\'s position on procedure time in MIPO (Minimally Invasive Plate Osteosynthesis) for distal radius fracture. The hypothesis was that there was a correlation between procedure time and the surgeon\'s position in relation to the operated side. Thirteen surgeons (12 right-handed, 1 left-handed) operated on 421 distal radius fractures: 208 right-sided (R) and 213 left-sided (L). Surgeons stood either at the patient\'s head (H) or the feet (F). Procedure time and scar size were measured. Regardless of operated side (right or left), mean surgery time was 35.5 min (range, 14-71) with the surgeon at the head and 40.5 min (range, 11-119) with the surgeon at the feet. The difference (5 min) was statistically significant. When the right side was operated on, surgery time was 34.2 min (range, 14-66) with surgeon at the head and 41.1 min (range, 11-86) at the feet. The difference (6 min) was statistically significant. No other comparisons were significant. There was no correlation with surgeon\'s experience. Given that 1 min of operating room time costs between €10.80 and €29, savings of €54 to €145 per procedure can be achieved. The study hypothesis was confirmed, with a correlation between the surgeon\'s position in relation to the operated side and the duration of the operation. In conclusion, we recommend that surgeons position themselves at the patient\'s head for of distal radius fracture MIPO.

The Wide-Awake Local Anesthesia No Tourniquet (WALANT) method is a recent anesthesia option for surgery of the upper limbs based on the injection of an anesthetic solution containing adrenaline at the surgical site, hence circumventing tourniquet use. In a prospective study, we compared the functional outcomes using this anesthesia technique with those of the regional anesthesia (RA) technique for the surgical care of distal radius fractures (DRF). From November 2019 to June 2020, a non-randomized, single-center study was conducted with a cohort of 41 patients suffering from a DRF and who received volar plate fixation at a university hospital center. Twenty-one patients had WALANT surgery and 20 had RA with installation of a tourniquet. Over a period of 7 months, the clinical and radiological outcomes as well as the QuickDASH functional score were evaluated. Recovery of wrist function return to work, and analgesic withdrawal for the WALANT group occurred earlier than for the RA group. No noticeable differences were found regarding surgery duration or radiographic results. Using WALANT, functional wrist recovery occurs earlier than with RA. In our study, earlier analgesic stoppage, a quicker return to work and resumption of activity were observed with WALANT. As such, it should become part of the therapeutic arsenal for surgical treatment of DRF.

The aim of this study was to determine the effectiveness of early versus delayed motion on the functional outcomes in patients with distal radius fracture (DRF) treated with a volar locking plate. A systematic review and meta-analysis of randomized clinical trials was performed. An electronic search was performed in the Medline, Central, Embase, PEDro, Lilacs, Cinahl, SPORTDiscus, and Web of Science databases. The eligibility criteria included randomized clinical trials that compared the effect of early versus delayed motion on wrist and/or upper limb function, pain, grip strength, and wrist range of motion in subjects older than 18 years with DRF treated with a volar locking plate. Five clinical trials were included that met the eligibility criteria for the quantitative synthesis. At 6 weeks, the PRWE questionnaire showed a mean difference (MD) of -10.6 points (p < 0.001), the MD was -11.1 points for the DASH questionnaire (p < 0.001), -0.56 cm for pain on VAS (p = 0.01), 5.0 kg for grip strength (p = 0.01), 12.5 degrees for wrist flexion (p = 0.07), and 12.8 degrees for wrist extension (p = 0.05). All differences favored the early motion treatment. At 3 months of follow-up, only the DASH, pain on VAS, and grip strength showed significant differences in favor of early motion. At 1 year of follow-up, none of the variables studied were different between groups. In the short term, there was moderate to high evidence of clinically and statistically significant differences in the functional outcomes in favor of early versus delayed motion in patients with DRF treated with a volar locking plate. But these differences were not observed at 1 year of follow-up. PROSPERO registration no.: CRD42020158706.

The aim of this study was to know if applying continuous passive motion (CPM) in addition to routine exercises is more effective than routine exercises alone in pain reduction, range of motion (ROM) and function improvement after distal radius fractures (DRFs). In this randomized controlled trial, 21 patients with non-stabilized DRF after pin removal were randomly assigned to experimental and control groups. The experimental group received stretching exercises with CPM machine for 2×15min per session. Both groups received routine exercises for 1h, three times a week for 4 weeks. The primary outcome measure was pain evaluated on a visual analog scale (VAS), and the secondary outcome measures were disability evaluated by the patient-rated wrist/hand evaluation and ROM (goniometry) at 4, 6, and 12 weeks. Univariate analysis of covariance (ANCOVA) and a one-way repeated measure mixed model analysis of variance (ANOVA) were used for data analysis. Twenty-one participants completed the 12-week follow-up. Pain relief, ROM and functional improvement revealed that the treatment was successful in both groups. We detected no significant differences (p>0.05) between the two groups at the end of the follow-up period regarding pain, ROM, and function. Using a CPM machine had no additional effect on pain reduction, ROM and function improvement compared with routine exercises in patients with DRF.

Despite recent advances in the surgical management of distal radius fractures (DRFs), the optimal treatment remains controversial as different fixation methods often have similar clinical functional and radiographic outcomes. The objective of this study was to assess the differences in outcomes 1 year postoperatively between volar plating and combined plating for DRFs. In a retrospective cohort study, we evaluated 105 consecutive patients operated with either a volar locking plate or combined dorsal and volar plating. The primary outcome was wrist range of motion (ROM). Secondary outcome measures included hand grip strength, visual analog scale (VAS) pain scores, radiographic examination and patient-related outcome measures. Patients treated with combined plating had significantly inferior wrist flexion, extension and ulnar deviation. The radiographic Batra score 1 year postoperatively was similar for both groups. The PRWE (patient-rated wrist evaluation) score was 16 for the volar plating group and 14 for the combined plating group. The QuickDASH (Quick disabilities of the arm, shoulder and hand) score was 9 for the volar plating group and 16 for the combined plating group. VAS pain scores were 0 at rest and 2 during activity for both groups. Grip strength was similar between the two groups. Hardware removal was done in 18/78 patients for the combined plating group and 1/27 for the volar plate group. Two patients operated with combined plating had tendon ruptures. Our findings indicate that both methods can yield satisfactory clinical and radiographic outcomes. However, combined plating resulted in inferior wrist ROM and substantially higher frequency of hardware removal. The potential advantages of combined plating in stabilizing a comminuted DRF must be balanced by the potential drawbacks such as inferior wrist ROM and higher frequency of hardware removal.

The aims of the study were to determine whether a volar lunate facet fragment is present in 67 displaced intra-articular distal radius fractures and to investigate which factors are associated with reduction loss after treatment with a volar plate and locking screws. The fractures were analyzed preoperatively with three-dimensional computed tomography. The volar lunate facet fragment was present in 42 fractures. Reduction loss occurred in five wrists and in two of those, the carpus was subluxated. Loss of reduction was associated with a short palmar cortex (9mm or less) of the volar lunate facet fragment. This study has shown that measuring the length of the palmar cortex of a volar lunate facet fracture fragment may be useful for identifying distal radius fractures that have a higher risk of displacement after treatment with a standard volar plate and locking screws.

We sought to investigate the effects of early manual therapy on functional outcomes in patients treated with volar plating of a distal radius fracture (DRF). This was a prospective, single-blinded, randomized controlled trial. Patients treated with volar plating of a DRF were randomly assigned to either Early Manual Therapy Group (EMTG, n=19) or Standard Physiotherapy Group (SPG, n=20). While SPG received standard physiotherapy, EMTG received standard physiotherapy plus Mulligan\'s Mobilization with Movement technique two sessions a week, through 12 weeks. Function, pain intensity, range of motion, grip strength and the level of disability were assessed using the Patient Rated Wrist Evaluation (PRWE), Visual Analog Scale (VAS), goniometer, hand dynamometer and Disabilities of Arm, Shoulder and Hand (DASH) Questionnaire, respectively. Measurements were made at 3, 6, and 12 weeks postoperatively. Of the 54-screened patients, 39 met the inclusion criteria and were randomized. In total, 32 patients (EMTG, n=15; SPG, n=17) were analyzed. EMTG had significantly better DASH score and wrist flexion at 12 weeks, less pain and better PRWE total score, wrist extension, ulnar/radial deviation, supination and grip strength at all time points. Moreover, wrist flexion increased more with the addition of early manual therapy than standard physiotherapy alone (26.50±13.19 versus 16.21±16.06). The addition of early manual therapy to standard physiotherapy may contribute to better functional outcomes and be more effective in increasing wrist flexion in patients treated with volar plating of a DRF.

The aim of this study was to evaluate the prevalence of arthroscopic scapholunate (SL) and/or lunotriquetral (LQ) laxity and triangular fibrocartilaginous complex (TFCC) injuries in patients who have an intraarticular fracture of the distal radius and to correlate these lesions with fracture type. Fifty-seven intraarticular radius fractures, whether or not they were associated with an ulnar styloid fracture, were evaluated and treated by arthroscopy. Scapholunate and lunotriquetral ligament injuries were classified according to the EWAS classification. TFCC lesions were assessed according to Palmer\'s classification. Each injury was documented through preoperative X-rays and a CT scan. Fracture type and soft tissue injury were not significantly associated one to another. Arthroscopic examination revealed at least one soft tissue injury in 39 intraarticular fractures of the distal radius (68.4%). Twenty-five percent of arthroscopic SL laxities (including severe EWAS 3 injuries) were not detected on standard radiographs. Arthroscopic SL laxity was present in 8 of 11 cases (72.7%) of radial styloid fracture and in 15 of 25 cases (60%) of fractures with at least one radial styloid component. There was no association between LQ integrity and fracture type. Ulnar styloid fractures (base or tip) and TFCC lesions were significantly correlated (P<0.0001). The prevalence of soft tissue lesions secondary to intraarticular fractures of the distal radius was 68.4%. However, there was no statistically significant relationship between the different types of radius fractures and soft tissue injuries. On the other hand, ulnar styloid fracture was predictive of TFCC injury.

The aim of this study was to use a compression screw in the epiphyseal medial orifice of a volar plate to reduce and stabilize the die-punch fragment in distal radius fractures (DRF) undergoing open reduction and internal fixation (ORIF). The main hypothesis was that the range of motion (ROM) in supination would be poorer when a standard screw was used. Our case series included 19 patients with an average age of 59 years (24-91) (SD -35.32) (10 male patients and 9 females) who underwent ORIF of DRFs with a volar plate. Group I included 10 patients in which the die-punch fragment was fixed with a standard locking screw and group II included the 9 patients in which the die-punch fragment was fixed with an angle stable compression screw through both cortices. At the 6-month follow-up visit, the average ROM in flexion was 83% in group I and 81% in group II (-2.327 [-13.657; 8.960]), the ROM in extension was 91% and 89% (-2.754 [-13.410; 7.602]), the ROM in pronation was 100% and 102% (+3.178 [-5.242; 11.457]), the ROM in supination 100% and 97% (-3.171 [-10.825; 4.537]), the pain level was 0.6/10 and 1/10 (+0.106 [-0.809; 0.977]), the QuickDASH score was 8.1/100 and 17.17/100 (+5.790 [-2.934; 15.012]), the PRWE was 6.2/100 and 22/100 (+13.109 [4.416; 22.779]) and the grip strength was 95% and 74% of the contralateral side (-12.478 [-24.832; 0.538]). No complications, nonunions or revision surgery were reported in the two groups. One case of secondary displacement of the die-punch fragment occurred in each group. The main hypothesis was not proven. In conclusion, despite what several biomechanical studies have suggested, the use of double-threaded compression screws for die-punch fragment fixation in DRFs does not improve the clinical outcomes compared to standard locking screws.
