Wide-Awake Approach for Flexor Digitorum Superficialis Tendon Transfer Followed by Early Active Mobilization

Background The standard clinical practice to treat closed ruptures of the flexor digitorum profundus (FDP) tendons includes free tendon grafting; however, it is not suitable when the muscle amplitude of the ruptured FDP is not sufficient. We report outcomes of six patients who underwent flexor digitorum superficialis (FDS) tendon transfer of the ring finger using the wide-awake approach to repair the closed rupture of the FDP tendon of the little finger in zone 3 or 4. Methods The patients were identified by reviewing our institutional billing records from January 2012 to October 2019 for the International Classification of Disease 10 code M66.3 that describes the diagnosis as “spontaneous rupture of flexor tendons.” Results The patients comprised two men and four women with an average age of 72.2 years (standard deviation [SD], 8.4 years). All patients were hospitalized after surgery to undergo early active mobilization. The average total active motion at the final evaluation was 201.8° (range: 85–248°). According to Strickland’s criteria, outcomes were excellent for two, good for three, and poor for one patient. No patients complained about the ring finger. Conclusion These results suggest that FDS tendon transfer is recommended when the muscle amplitude of the ruptured FDP is insufficient. We believe that the wide-awake approach and early active mobilization may contribute to satisfactory outcomes.

A Silent Closed Rupture of the Flexor Digitorum Profundus on the Index Finger: An Unsolved Mystery

We report the case of a patient who fully recovered from a closed flexor tendon rupture through a two-stage flexor tendon reconstruction using silicone rods, despite a considerable delay in treatment. A 17-year-old male patient visited our clinic with a sudden inability to flex his left index finger, although there were no signs of injury. Magnetic resonance imaging revealed an extensive rupture of the flexor digitorum profundus from the base of the distal phalanx to the proximal phalangeal joint of his left hand. After a two-stage tendon graft operation was performed, the patient regained full flexion of the index finger and was able to hold a fist without any limitations in range of motion. Complete rupture of tendons usually accompanies history of trauma or underlying tendon pathology. In our case, however, the tendon rupture occurred silently with no obvious underlying causes. It is important to recognize the signs to evaluate the underlying structures for appropriate management and treatment. Even with considerable delay, the patient may regain full function of the tendon.

A Simple and Quick Tendon Transfer Technique to Restore Thumb Extension.

Extensor pollicis longus (EPL), the long extensor tendon for the thumb, is one of the commonest tendon to rupture and require treatment. In case of closed rupture of EPL, direct repair is usually not possible, requiring tendon reconstruction to restore function. Traditionally, extensor indicis proprius (EIP) tendon is transferred under general or regional anaesthesia through two (or more) incisions. The author proposes and demonstrates that it is possible to carry out this transfer through one short incision under local anaesthesia with good outcome and minimal complications.

Painful Pseudotendon Caused by Closed Rupture of the Flexor Carpi Radialis Tendon: A Case Report and Literature Review

Closed rupture of the flexor carpi radialis tendon in non-rheumatoid patients is uncommon. We report a case of a 53-year-old woman who developed painful pseudotendon after a complete rupture of the flexor carpi radialis tendon due to osteoarthritis of the scaphotrapezial trapezoidal joint.

Closed rupture of flexor digitorum profundus in zone III

Closed ruptures of the flexor digitorum profundus (FDP) tendon cause a loss of active flexion at the distal interphalangeal joint. Commonly referred to as a ‘jersey finger’ because of its association with tackling sports, the distal aspect of FDP is avulsed from its insertion on the distal phalanx in zone I, with or without a fragment of bone. Because of this classic injury mechanism and pattern, providers may not seek advanced imaging beyond plain radiographs. Although rare, injury to FDP more proximally may occur. More often this injury is associated with a weak underlying tendon because of repetitive microtrauma or anomalous anatomy, for example. We present a case of a closed rupture of the FDP in zone III, and stress the importance of maintaining a high clinical suspicion and the potential use of adjunct ultrasound imaging to localise the site of injury.

Hand It to Dr Google: The Quality of Online Information on Ganglion Cysts

Background: The internet is becoming a common source of health information for hand surgery patients. This study evaluates the quality of web-based resources on ganglion cysts of the hand. Methods: We completed a search for “ganglion cyst” on 3 search engines (Google, Dogpile, and Yippy). The quality of the top-100 patient education websites was assessed using a validated internet rating tool. Websites were evaluated based on affiliation, accountability, currency, interactivity, website organization, readability, coverage, and accuracy. Results: Of the 100 websites, the majority (74%) had commercial affiliations. Only 34% of websites identified an author, and even fewer identified the authors’ credentials (27%) or affiliations (26%). A third of the websites cited references, and less than half provided an update date. The average readability based on Flesch-Kincaid grade level was 9.2, and only 3% could be read at or below 6th grade reading level. Prevention was the most poorly covered topic at 13% due to omission. In all, 66% of the websites were completely accurate in terms of global accuracy. Websites were most likely to present inaccurate information on treatment, often failing to mention conservative treatment (watch-and-wait approach) or promoting the use of natural health products. We also found 5% of websites presented closed rupture of the ganglion cyst as a legitimate home remedy. Conclusions: The overall quality of online information on ganglion cysts is highly variable and may occasionally be harmful for patients. It is increasingly important for physicians to prompt patients about their internet use.

Delayed presentation of extensor pollicis longus tendon injury treated using extensor indicis proprius tendon transfer

Spontaneous closed rupture of EPL tendon are frequently associated with rheumatoid arthritis, Colles fracture, sports related injury. In cases of delayed presentation direct tendon repair is not feasible and a tendon transfer is usually recommended. In this study we evaluated the results of extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfers for EPL ruptures. Four patients, (two male and two females); mean age 32 years (range 20 to 45 years) with EPL tendon rupture underwent EIP to EPL tendon transfer. The mean duration from rupture to surgery was 4.5 weeks (range 4 to 6 weeks). Range of motion of the metacarpophalangeal (MCP), interphalangeal joints (IP) of the thumb and index finger of the operated side was compared with the normal side. The results were scored using geldmacher scheme, for the thumb four functions were scored, the radial abduction angle, the elevation deficit, the opposition distance and flexion extension deficit of MP and IP joints. The mean follow-up period was 5 months. All the four patients were able extend the thumb at MCP joint and oppose the thumb to the MCP of little finger after mean follow up of 5 months. Based on the questionnaire, the results of tendon transfer scored by three (75%) patients was excellent and by one (25%) patient was good. Independent extension of the index finger of operated hand was possible in all 4 patients. The procedure of EIP to EPL tendon transfer provides excellent result for extension of thumb. It is a safe procedure.
