A modified spica-splint in postoperative early-motion management of skier's thumb lesion: a randomized clinical trial.

BACKGROUND: Rupture of ulnar collateral ligament of the thumb (UCL) represents a frequent injury of the hand. Surgical repair is considered the gold standard but postoperative immobilization causes partial stiffness in a percentage of cases.

AIM: The aim of this paper was to assess the effectiveness of a postoperative functional hand-based splint for the thumb which allows immediate postoperative motion.

DESIGN: Randomized prospective clinical trial.

SETTING: The study was carried out at the Orthopedics and Hand Surgery Unit of The Catholic University School of Medicine, Rome, Italy.

POPULATION: Thirty consecutive patients, with a diagnosis of acute complete tear of the UCL, were selected to be treated surgically (predominantly men, mean age 39). Cases presenting associated injuries were not included.

METHODS: Patients were randomized postoperatively into 2 groups of 15 (one using the new splint and the other using a standard spica splint). After four weeks of splinting, clinical outpatient evaluations were carried on (at one, two, six, twelve months) on both groups to evaluate: joint stability; pain; pinch strength; range of motion; time lost from work; sessions of physiotherapy.

RESULTS: Immediate postoperative motion of the operated joint produced faster and better functional results. No cases of recurrence were recorded.

CONCLUSIONS: Surgical repair, combined with active metacarpophalangeal motion allowed by the new functional splint, was effective, safe and well tolerated.

CLINICAL REHABILITATION IMPACT: Enhancing the patients' function and reducing the time of functional recovery, the reported treatment presents potential advantages in the management of this frequent acute hand injury.
