Rupture Of Flexor Digitorum Profundus Tendon Research Articles

Jersey Finger Repair

Jersey finger, also known as rugby finger, is an avulsion to the flexor digitorum profundus at its insertion on the base of the distal phalanx (zone I). It is frequently caused by forceful extension of the distal interphalangeal joint while actively flexing the flexor digitorum profundus. The tendon may tear from the distal phalanx independently or may avulse with a bony fragment. A classification system has been developed to categorize distinct injury patterns based upon the level to which the flexor digitorum profundus tendon retracted and the presence or absence of a bony avulsion fracture. Flexor digitorum profundus tendon rupture has been reported in all age groups but is most common in athletes. The injury frequently occurs during contact sports, notably American football and rugby, when grabbing the jersey of an opposing player as the player pulls or runs away. Surgical repair is the definitive treatment for all cases of complete rupture of the flexor digitorum profundus tendon. This video demonstrates a surgical approach using the suture anchor technique to repair a jersey finger injury.

Are Flexor Tendon Ruptures Ever Spontaneous? - A Literature Review on Closed Flexor Tendon Ruptures of the Little Finger.

Background: When closed ruptures of flexor tendons of fingers occur, there is often an identifiable pathology, which should be addressed in the same surgical setting as the tendon repair. The concept of "spontaneous" tendon rupture, occurring in the absence of identified pathology, however, has also been reported in a significant number of papers. This controversy has prompted us to do a review of the existing literature. Methods: We did a review of cases of closed ruptures of the flexor digitorum profundus (FDP) of the little finger in existing literature. Fifty-three publications were retrieved by searching "FDP tendon rupture" and "little finger" using PubMed database. We analyzed data such as the zone of rupture noted intra-operatively; and any precipitating factors, pathology or trauma. We also conducted a review on papers which discussed the concept of "spontaneous rupture". Results: Fifty-three publications were retrieved. There were 8 cases of ruptures in Zone I; 2 in Zone II; 30 in Zone III; 59 in Zone IV and 5 in Zone V. Majority of cases were associated with an element of trauma of varying severity, or pathology. A precipitating cause was not documented in 12 cases. Amongst all 36 cases of ruptures labelled as "spontaneous", only 1 case was truly "spontaneous" without any associated trauma or pathology. Conclusions: Most reports labeled as spontaneous rupture occurred in Zone III, where tendon ruptures are rare. There are documented pathological causes or evidence of trauma to most of these cases. We conclude these ruptures may have been mislabeled as spontaneous ruptures. Bearing in mind the propensity for tendon excursion, we suspect the lack of documentation of exploration in proximal zones contributed to this mislabeling. Understanding this concept of non-spontaneity to most tendon ruptures and the common sites of rupture or pathology is crucial for a surgeon to make strategic incisions and minimize future recurrence.

Acute Rupture of Flexor Digitorum Profundus Tendon Associated with Distal Radius Fracture: A Case Report

Even though fractures of the distal radius are the most common fracture of the upper extremity, complications concerning the injury are relatively poorly reported. It is thought that flexor tendon ruptures associated with distal radius fracture are caused by attrition by rough surfaces of malunited fracture and irritation by fixation implants. The majority of reported cases usually presents with the complication four or more weeks after the injury. Extensor tendon damage is thought to be more common than flexor tendon damage in patients with distal radius fractures. Concurrent flexor digitorum profundus tendon rupture with distal radius fracture is very rare. Therefore, we are Acute Rupture of Flexor Digitorum Profundus Tendon Associated with Distal Radius Fracture: A Case Report

Avulsion Rupture of Flexor Digitorum Profundus in Zone 1, Diagnosed in Early Stage

Received: December 3, 2014 Revised: May 6, 2015 Accepted: May 24, 2015 Correspondence to: Jae-Cheon Sim Department of Orthopedic Surgery, Sahmyook Medical Center, 82 Mangu-ro, Dongdaemungu, Seoul 130-711, Korea TEL: +82-2-2210-3324 FAX: +82-2-2212-2673 E-mail: crash1401@naver.com Avulsion injury of the flexor digitorum profundus (FDP) tendon from the distal phalanx is considered as a rare injury. We report a patient who sustained a FDP tendon rupture insertion on her fifth finger as a result of a closed, hyperextension with no accompanying laceration or predisposing pathologic condition. Preoperative ultrasonography showed complete rupture of FDP and the gap between the tendon ends. According to the classification by Leddy and Pacter, this case is type II. The reconstruction of flexor tendon using pull-out suture and tie-over button. We are reporting a case with brief review of literatures.

Tendon rupture of the flexor digitorum profundus of the little finger secondary to hamate non-union

Several cases of hamate fracture and non-union have been reported. The hook of the hamate acts as a pulley for the flexor tendons for the little and ring fingers. Hamate non-union is frequently associated with irritation of the adjacent soft tissues. We report the case of hamate non-union that was only detected because of a flexor digitorum profundus tendon rupture in the little finger, associated with tendinopathy of both flexor tendons of the ring finger.

Spontaneous Flexor Tendon Rupture of the Flexor Digitorum Profundus Secondary to an Anatomic Variant

We report a case of the flexor digitorum profundus tendon rupture of the little finger, which was predisposed by an anatomic variation of the tendon. Intraoperative findings and magnetic resonance imaging of the opposite hand suggested that the flexor digitorum profundus tendons of the ring and the little finger bifurcated. The patient had tendon reconstruction and regained function. We believe that reconstructing the tendon so that it resembles the normal anatomy prevents the recurrence of tendon rupture.

Avulsion Fracture of the Hamulus From Clay Gunshot Sport: A Case Report

We report a case of hamulus (hook of hamate) fracture nonunion and secondary flexor digitorum profundus tendon rupture caused by repetitive wrist hyperextension sustained during clay shotgun shooting. The hyperextension caused avulsion of the hamulus by the pisohamate ligament. The hamulus was excised and a flexor digitorum profundus tendon transfer of the ring to small finger side to side was performed with satisfactory outcome.

THE ROLE OF MAGNETIC RESONANCE IMAGING IN LATE PRESENTATION OF ISOLATED INJURIES OF THE FLEXOR DIGITORUM PROFUNDUS TENDON IN THE FINGER

Four patients had magnetic resonance imaging (MRI) after a clinical diagnosis of a flexor digitorum profundus tendon rupture of the hand. The delay before presentation ranged from 1 to 5 weeks. Three patients had closed ruptures and one had a minor laceration which had healed. MRI showed proximal retraction of the profundus tendon to the palm in two patients and limited retraction in the other two. MRI provides important preoperative information for surgical decision-making and planning in patients who present late with closed flexor tendon injuries of the hand.

Traumatic rupture of the profundus tendon proximal to the lumbrical origin

Traumatic flexor tendon ruptures are rare in patients without rheumatoid arthritis. A case of closed flexor digitorum profundus tendon rupture in the palm, proximal to the lumbrical origin, is presented. Thorough patient evaluation revealed no associated tendinous or bony pathology.
