Fracture-associated nerve dysfunction

Radial Nerve Paralysis in Diaphyseal Fractures of the Humerus

One of the most common complications associated with a diaphyseal humeral fracture is the development of a radial nerve injury. We conducted a study to analyze the degree of recovery and prognostic factors associated with radial nerve palsy in patients with diaphyseal humerus fractures. We retrospectively analyzed 28 patients who presented to the Hospital La Fe, Valencia, Spain, with a diaphyseal humerus fracture associated with radial nerve injury between 2010 and 2020. A total of 14.3% (n = 4) of the patients in our cohort had open fractures and 85.7% (n = 24) had closed fractures. There were no statistically significant differences between the type of treatment and the type of fracture (p = .13). There were also no significant differences between the type of treatment and recovery time (p = .42). There was a statistically significant difference (p = .04) in the mean recovery time for patients with preoperative radial nerve injuries (11.9 months) compared with patients who sustained a radial nerve injury secondary to surgical repair of the fracture (8.6 months). The difference in recovery time between patients with open and closed fractures was not statistically significant (p = .3). Results of the study showed that the type of fracture (i.e., open or closed) did not affect radial nerve palsy recovery time. Patients who sustain radial nerve injuries secondary to a surgical repair have a shorter recovery time than patients who sustain primary radial nerve injuries.

Analysis of Early Neurovascular Complications of Pediatric Supracondylar Humerus Fractures: A Long-Term Observation

Purpose. Analysis of early vascular and nerve complications of supracondylar humerus fractures in children. Material and Methods. 220 children hospitalized in the Pediatric Trauma-Orthopedic Department in the years 2004–2014. The group consisted of 143 males and 77 females. Results. Acute neurovascular complications occurred in 16.81% of patients with displaced supracondylar fracture (37 children). Nerve damage was found in 10% of patients with displaced fracture (22 children). The most injured nerve was median nerve; this complication occurred in 15 patients (68.18%). The total nerve function returned after average of 122 days (0–220 days after surgery). Symptoms of vascular injury occurred in 7.7% children with displaced fracture (17 children). Conclusions. (1) In children with supracondylar fracture the most often injured nerve is median nerve. (2) The incidence of vascular and nerve complications positively correlates with the progression of fracture according to Gartland classification.

Plate osteosynthesis of humeral diaphyseal fractures associated with radial palsy: twenty cases

BACKGROUND

Surgical management of humeral fractures associated with radial nerve palsy remains controversial. Some advocate surgical treatment in emergency while others recommend nonoperative treatment.

PURPOSE

The aim of the study was to assess nerve recovery in a series of patients treated with open reduction and internal fixation (ORIF) with plate for humeral fracture associated with radial nerve palsy. We hypothesised that surgical treatment with ORIF in emergency allows good nerve recovery.

METHODS

We conducted a retrospective study on 20 patients out of 225 humeral shaft fractures operated between 1995 and 2012. There were 11 women and nine men, with a mean age of 51 ± 22 years (23-93). The fractures were located in mid third of the shaft in 15 cases (75 %), distal third in four (20 %) and superior third in one (5 %). Mean delay for surgical treatment was three days (zero to 15). The plate was positioned at the medial face in 16 cases (80 %) and posterior face in four (20 %). In six cases, the radial nerve was not seen (30 %). In the 14 cases where it was seen (70 %), it was continuous. Neurolysis was performed in seven cases (35 %).

RESULTS

Fifteen patients (75 %) had a good nerve palsy recovery, with a mean delay of ten months (six to 12). Statistically significant correlation was observed between delay of surgical treatment and delay of radial recovery (p = 0.0166 ; Rho = - 0.53). Early osteosynthesis was correlated with better nerve recovery. One patient required complementary nerve surgery and another tendon transfer. Bone healing was obtained in all cases. Concerning functional outcomes, mean QuickDASH, a shortened version of the Disabilities of the Arm, Shoulder and Hand (DASH) score, was 9 ± 17 (0-59), and 85 % of patients were able to recover their previous physical activities.

CONCLUSION

ORIF by plate of humeral shaft fracture with radial nerve palsy in emergency allows good palsy recovery (75 %) with a short delay (about three days).
