Complex injuries of upper extremity are among the most challenging cases for the treating physician, especially when comminuted fractures, neurovascular injuries or extensive soft tissue loss are accompanied with. Reconstruction of the skeleton is usually very difficult since plates, screws, or external fixation do not always provide sufficient stability. Recently, flexible titanium intramedullary nails that initially developed for pediatric trauma, were introduced in treatment of open and complex injuries of upper extremity.

From 1995 – 2001 20 patients (16 male, 4 female) with a mean age 28 years (15–60 years) were managed at our department with flexible titanium intramedullary nailing. 12 sustained forearm fractures, humeral ones, as well as 4 concomitant fractures of forearm and humerus.Nailing was performed either closed with image intensifier or open through the wound with minimal stripping. Postoperatively a splint was applied. Rehabilitation regime was adjusted to soft tissue care; when severe soft tissue wasn’t encountered, early mobilization of the arm was applied.

Union rate was conceivably high, in a relative short time. In 3 cases of segmental fractures of radius, nail removal and subsequent fixation with plate and screws due to nonunion of distal site, was necessitated.

Operative technique is simple, fast and reliable providing satisfactory reduction, stable fixation with minimal further tissue trauma and mostly early mobilization

In this report we present the results of the primary suture of the flexor tendons in zone II, in 198 patients who were operated in our department between 1998 and the first months of 2001. 142 were male from 16 to 65 years old and 56 were female between 14 to 60 years old. Children below 14 years old are not included in this report.

The majority of patients in this review reported an accident during dancing and late night activities. Patients with complex injuries such as fractures of phalanges, phalangeal dislocations and extensive soft tissue laceration were excluded. The majority of the patients operated immediately within the first 48 hours and only 28 patients (14, 5%) were operated with a delay ranging between 1 – 5 weeks. The suturing technique was variable in all cases. A Bruner (zig-zag) incision was utilized to facilitate. The tendon was sutured using a standard Kleinert technique and 4.0 nylon sutures as supportive sutures, 5.0 nylon sutures were used to suture the epitendon in a continuous fashion. A dorsal splint holding the wrist in 40° of flexion and the MP joints in 70° of flexion and PIPs and DIPs in extension was used postoperatively. Early mobilization was initiated (shortly after surgery, 3 – 4 days) and lasted 4 weeks. After this period the patient underwent a program of full active motion for an additional 4 weeks. They finally allowed to perform freely after a 12-week postoperative period.

We used the Kleinert score to evaluate the surgical results. According to this score results were found to be: Excellent in 80 patients (40%), good in 60 pts (30%), fair in 22 (12%) and poor in 16 pts (8%). Despite the satisfactory overall results we observed a high incidence of tendon ruptures (10%) in 20 patients and this may be related to poor follow up and rehabilitation conditions. No other complications (infection, hematoma formation, and skin slough) were observed in these patients.
