Abstract Background: Percutaneous screw fixation was introduced for acute scaphoid fractures through K-wire-assisted reduction and maintenance, and the effectiveness of the methods was evaluated.Methods: Ten patients with acute scaphoid fractures were consecutively treated with the proposed technique from January 2015 to December 2018. With the wrist placed in ulnar deviation, one K-wire was introduced perpendicularly through the styloid process of radius into the proximal pole of scaphoid under fluoroscopic guidance. The scaphoid fragment was reduced by dorsiflexing the wrist and translating the distal pole into an extended position. A headless compression screw was then inserted in a standardised manner. Operation time, time to union, time to return to previous activity and complication were recorded. Function outcomes including pain, work status, range of motion (ROM) and grip strength were assessed according to the modified Mayo wrist scoring system.Results: Final follow-up examination was performed on an average of 12 months (range, 10–15 months) after surgery. No immediate postoperative complication occurred. All scaphoid fractures united at an average of 9.2 weeks (range, 7–11.4 weeks). The following average values were achieved: operation time was 48.2 minutes (range, 38–65 minutes), the time that patients returned to previous activity levels was 9.4 weeks (range, 7–11 weeks) and function scores were 92.5 (range, 80–100). At 3 months post-operation, the wrist range of motion was generally 62.5° wrist extension (range, 50°–70°) and 68.2° wrist flexion (range, 55°–75°). Grip strength was approximately 40.1 kg (range, 28–45 kg) and 83.5% (range, 85%–100%) of the contralateral sides. The mean post-operative height-to-length ratio was 0.61.Conclusions: Our novel percutaneous screw fixation method is beneficial to minimise injury to the blood supply of the scaphoid. Primary percutaneous screw fixation for acute scaphoid fractures is a superior method with reduced time to bony union, early return to daily activity or employment and predictably lessened complications of wrist stiffness, diminished grip strength, delayed union, non-union and osteonecrosis.Trial registration: Clinicaltrials.gov; NCT04482868; Registered 19 July 2020-Retrospectively registered.

Abstract Background Most of the acute scaphoid fractures have been treated nonoperatively in a cast or by open surgery. Percutaneous screw fixation was introduced for acute scaphoid fractures through K-wire-assisted reduction and maintenance, and the effectiveness of the methods was evaluated. Methods From January 2015 to December 2018, a total of 20 patients were recruited to the study and 10 patients were randomly allocated to the open reduction and percutaneous groups respectively. Different groups received open reduction and internal fixation or percutaneous screw fixation. Function outcomes including the range of motion and grip strength were assessed according to the modified Mayo wrist scoring system. Results Final follow-up examination was performed on an average of 12 months after surgery. No immediate postoperative complication occurred. All patients achieved solid union as confirmed by CT scans. A significant increase in the functional recovery of the injured wrist in the percutaneous group than they were in the open reduction group. Conclusions Our novel percutaneous screw fixation method is beneficial to minimise injury to the blood supply of the scaphoid. Primary percutaneous screw fixation for acute scaphoid fractures is a superior method with reduced time to bony union, early return to daily activity or employment and predictably lessened complications of wrist stiffness, diminished grip strength, delayed union, non-union and osteonecrosis.

Scaphoid Fractures

Percutaneous screw fixation of undisplaced fractures of the scaphoid waist has gained popularity but remains technically demanding. This study describes a transtrapezial modification of the volar percutaneous technique and reports the results in 41 patients. The patients were evaluated at a mean of 36 months (range 14–68 months) after surgery. All fractures healed within 10 weeks (mean 6.4 weeks). Functional ranges of wrist motion and grip strength were achieved in all patients. Radiographs showed accurate central placement of the screw in all patients and no degenerative changes were seen at the scaphotrapezial joint. In three patients, the screw was removed because it was prominent at the scaphotrapezial joint.

Abstract Background There are some difficulties in treating proximal scaphoid nonunion, mainly including poor vascularity of the proximal scaphoid fragment and limited space for a stable fixation in the proximal scaphoid fragment. This study reports the outcomes of treating proximal scaphoid nonunion with arthroscopic assist for reduction, bone grafting and screw fixation across the scapholunate (SL) joint. Methods Between 2008 and 2017, 21 patients were enrolled. Fracture healing and change in the lateral SL angle and SL gap were evaluated. Functional outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH) score, wrist range of motion, grip strength, and the Visual Analog Scale (VAS) for pain. Results Nineteen patients achieved fracture healing and their mean follow-up duration was 31.3 months (24–120 months). The average fracture healing time was 16.3 weeks (10 to 28 weeks). From the preoperative to the postoperative final evaluation, there was some significant improvement in wrist function, including wrist flexion from 54.5o to 67.4o, wrist extension from 62.3o to 71.7o, DASH scores from 52.4 to 21.4, VAS during activity from 4.6 to 2.1, and grip strength from 9.6 kg to 24.7 kg. The lateral SL angle also improved significantly, from 82o to 66o. Seventeen patients requested screw removal after fracture healing because of their cultural belief in not leaving hardware in the body. No significant SL gap widening was noted after screw removal in the sequential follow-ups. Conclusions Using arthroscopic-assisted reduction, bone grafting and screw fixation across the SL joint in proximal scaphoid nonunion treatment, satisfactory functional and radiographic outcomes can be achieved.

Trapezial excision arthroplasty with ligament reconstruction and tendon interposition (LRTI) modified to include proximal trapezoid excision was performed on 12 wrists in 10 patients with symptomatic, isolated scaphotrapezial-trapezoid (STT) arthritis. Wrist range of motion, lateral pinch and grip strength, and analog pain scores were measured pre- and post-operatively. Mean follow-up was 18 (11–42) months. Post-operatively, reported pain scores uniformly decreased ( p < 0.0001). Mean range of wrist flexion increased from 48 to 53° ( p < 0.05) and extension from 51 to 55° ( p < 0.05). There was also an overall increase in mean grip strength from 15.6 to 19.2 kg and pinch strength from 3.5 to 4.3 kg. Modified Mayo Wrist Scores were excellent in six cases, good in three, and fair in one. Our results suggest that modified total trapezial, partial trapezoidal excision and LRTI could be an effective surgical alternative in cases of isolated STT arthritis.

Abstract Background Grip strength and wrist range of motion (ROM) are important metrics used to evaluate hand rehabilitation and outcomes of wrist interventions. Published normative data on these metrics do not recognize the contribution of forearm rotation. This study aims to identify and quantify variations in grip strength and wrist ROM with forearm rotation in healthy young individuals. Materials and Methods Wrist ROM and grip strength were measured in 30 healthy volunteers aged 23 to 30. Participant demographics, grip strength, and wrist ROM (wrist flexion and extension, ulnar and radial deviation) at three forearm positions (full supination, neutral, and full pronation) were measured using a digital dynamometer and standard goniometers. Data analysis was conducted using a one-way repeated measure ANOVA. Forearm position values were compared using post hoc analysis. Results Grip strength in males was greatest in neutral position (males: nondominant 51.4 kg, dominant 56.1 kg) followed by supination (males: nondominant 46.6 kg, dominant 51.7 kg) and weakest in pronation (males: nondominant 40.1 kg, dominant 42.9 kg). Grip strength in females was similar between supination (nondominant: 26.1 kg, dominant: 28.5 kg) and neutral (nondominant: 27.4 kg, dominant: 29.1 kg) positions, but both were greater than in pronation (nondominant: 22.3 kg, dominant: 24.1 kg). Wrist flexion in males was significantly reduced in supination compared with neutral and pronated positions (nondominant: supination 63.1°, neutral 72.6°, pronation 73.3°; dominant: supination 62.4°, neutral 70.2°, pronation 70.3°), whereas not significant wrist flexion in females was also weaker in supination (supination 74.4°, neutral 79.9°). Wrist extension in males was greater in pronation (supination 64.6°, pronation 69.5°) whereas females showed no significant difference in any of the forearm positions. Ulnar deviation in males did not differ with forearm position, but females demonstrated greater ulnar deviation in supination on the nondominant hand (supination 44.6°, pronation 33.2°). Whereas there was no difference in radial deviation with forearm position in females, it was markedly greater in pronation versus supination on both sides in males (nondominant: supination 16.3°, pronation 24.6°; dominant: supination 15.4°, pronation 23.9°). Conclusion This study characterizes variations in grip strength and wrist ROM in three forearm positions in healthy young individuals. All measurements differed with forearm rotation and were not influenced by hand dominance. These results suggest that wrist ROM and grip strength should be evaluated in different positions of forearm rotation, rather than a fixed position. This has functional implications particularly in patients involved with specialized activities such as sports, instrument-playing, or work-related activities.
