Abstract:

Objective

To review the implementation and outcomes of emergency repair and reconstruction surgery of spaghetti wrist injury and to summarize characteristics and key points of this injury and its management.

Methods

This research reviewed 27 cases (24 males and 3 females) of severe spaghetti wrist injury who received emergency repair and reconstruction surgery between January, 2020 and December, 2021, at our hospital. Patients were divided into working accident group (13 cases) and living-related group (14 cases) according to the place of injury, aging from 15 to 70 years old (45±14 y). Outcomes and complications were followed postoperatively. Numbers of lacerated structures, mechanisms of injury, Noaman's outcome evaluation system and DASH score were compared.

Results

In the working accident group, (9.1±2.9) ventral tendons and (2.2±0.5) dorsal tendons were lacerated on average, with 17 arteries and 23 nerves transected in total. Nine cases of fractures were also observed. This group was followed (17.8±5.8) months and one temporary infection was observed and cured. A rate of at least 61.5% in each aspect of Noaman's outcome evaluation system was received with an average of (17.2±4.7) in DASH score. In the living-related group, (9.1±2.3) ventral tendons and (1.9±0.6) dorsal tendons were lacerated on average, with 20 arteries and 25 nerves transected in total. No fracture was observed. This group was followed (16.0±4.9) months and one temporary infection was observed and cured. A rate of at least 57.1% in each aspect of Noaman's outcome evaluation system was received with an average of (13.9±6.9) in DASH score. There were significant differences in the aspects of side of injury (χ2=23.280, P<0.05), mechanism of injury (χ2=27.000, P<0.05) and type of fixation (χ=6.608, P<0.05). However, there was no significant difference in the aspects of numbers of injured tendons, nerves and vessels, Noaman's outcome evaluation system or DASH score. Besides, the living-related group showed a tendency of more vulnerable radial structures.

Conclusions

Multiple flexor and extensor tendon injuries were observed if the injury was composed of simultaneous laceration of main nerve and vessel of the wrist. Injury side can be related to injury site, according to which the surgeon shall adjust reconstruction strategies. Although limb functionality was partially improved after in time repair and systematic rehabilitation, severe spaghetti wrist injury still remains challenging for orthopedists. Effective teamwork, great skills in repair surgery and systematic rehabilitation would rescue the motor and sensory function of the injured limb and improve the prognosis.
