Case 2.12
Published in Monica Fawzy, Plastic Surgery Vivas for the FRCS(Plast), 2023
What do you mean by centralization and radialization of the ulna?Centralization is an option in patients with good elbow movement and involves wrist distraction followed by repositioning of the third metacarpal over the ulna. Radial deviation is counteracted with a closing wedge osteotomy of the ulna and ulnar carpus, and ulnar tendon transfers of FCR, ECRB and ECRL.Radialization is reserved for those with reduced movement at the elbow level and involves wrist distraction followed by repositioning of the scaphoid and second metacarpal over the ulna. Again, radial deviation is counteracted by FCR tendon transfer to FCU.

Biomechanics of the Hand and Wrist

The action of radial deviation and extension followed by ulnar deviation and flexion is functionally important. For this reason, ECRL and FCU, the muscles that produce this movement, are among the most powerful. During this functional ‘dart throwing motion’, the scaphoid is effectively locked in flexion within the proximal row. Thus, this motion is essentially a mid-carpal movement. In the less common action of moving from ulnar extension to radial flexion, the scaphoid is free to move, and so this is a radiocarpal movement.

Wrist and forearm active range of motion (AROM) were measured using a goniometer (Table 2) (Norkin and White, 2009). All measurements were equal to the left forearm/wrist except ulnar deviation (UD). The patient’s symptoms were reproduced most significantly with active and passive wrist flexion at the end range. Wrist flexion was less painful with the addition of radial deviation (RD) and more painful with adding UD passively. Familiar pain was also reported during end range active and passive UD ROM. Wrist extension passive ROM with overpressure also reproduced patient symptoms. Wrist and hand ROM were deemed normal otherwise. Manual muscle testing of the forearm and wrist was performed, according to Kendall, McCreary, and Provance (1993), and was 5/5, pain-free.

Within patients with PLD/PLFD flexion/extension and ulnar/radial deviation were significantly worse in the injured compared to the uninjured wrist (mean difference −54°, 95% CI −77, −31, p < 0.001 and mean difference −29°, 95% CI −37, −20, p < 0.001), even when excluding patients with an arthrodesis (Table 2). For grip strength measurements in comparison to the uninjured wrist, only grip strength (mean difference −12.7 kg, 95% CI −19.7, −6, p = 0.002) was significantly worse in the injured wrist (Table 2). Patients without arthrodesis did not have a significant difference in grip strength between the injured and uninjured wrist. Grip strength of the patients’ injured side was median 80% of the uninjured side. Four patients had grip strength <75% of the uninjured side.
Ergonomics investigation for orientation of the handles of wood routers

EMG analysis for the left and right ECRB and BB showed no difference among the different handle configurations. The reason might be a trade off in the handles between the wrist extension, radial deviation and forearm flexion, as well as increased muscle activity due to vibration exposure for a nearly flexed elbow [46]. Analysis from the recorded videos showed that with greater wrist radial deviation, participants had a tendency to flex their forearm. Quite a similar response was seen in the study conducted by Straker and Mekhora [47], where trapezius activity was compromised for the lower monitor position in response to the neck flexion and forearm support.
