Patients between the ages of 6-18 who have applied to orthopedics emergency department due to hand injury and have been operated with flexor tendon injury, for the last 3 years, were retrospectively scanned from hospital record. Eligible patients for the study were informed about the study by telephone and requested to come hospital for further evaluations including sensory, motor and functional assessments.

The patients who agreed to participate to the study were assessed with a survey which included age, gender, height, weight and hand dominancy questions. Sensory, motor and functional assessments of the bilateral hand were performed.

Jebsen - Taylor Hand Function Test (JTHFT) was performed on both hands for evaluation of the fine and gross motor functions. It is a standard and objective assessment method of hand functions with activities similar to those performed in daily life. The test consists of 7 subtests. During the test, a separate period is kept for each step. The functions of both hands are evaluated by the following operations; writing, card turning, picking up small common objects, simulated feeding, stacking backgammon-checkers, moving large light objects and moving large heavy objects. Score of each subset is time (seconds) to complete the task and total score is calculated by summing of times for each sub-tests

The grip strength measured using a Baseline Hydraulic Hand Dynamometer according to the recommendations of the American Hand Therapists Association.. It was measured with the shoulder in the adduction, elbow 90 * flexion, forearm neutral and wrist 0-30 * dorsiflexion and 0-15 * ulnar deviation while the person was sitting position. The patient was asked to grasp the dynamometer as tightly as he could. For each side, 3 applications were made with an interval of 20 seconds and the average of these measurements was taken

Baseline Hydraulic Pinch Gauge was used to measure pinch strength. The measurement was made in the same position as the grip strength measurement. The pinch gauge was placed between the tip of thumb and the tip of the index finger and the patient was asked to squeeze as strongly as he could. For each side, 3 applications were made with an interval of 20 seconds and the average of these measurements was taken

Sensory examination was done with Semmes -Weinstein Monofilament test. This evaluation was started with the smallest monofilament and larger filaments were applied respectively, the test was stopped in the smallest monofilament the patient felt, and this value was recorded. Evaluations were made from the distal tips of the 1st and 2nd finger and the palmar surface of the 2nd metacarpophalangeal joint for the median nerve evaluation (monofilament test 1,2,3, respectively), distal tip of the 5th finger, the palmar surface of the 5th metacarpophalangeal joint and hypothenar area (monofilament test 4, 5, 6, respectively) for ulnar nerve evaluation.
