Anteroposterior Cannulated Screw Fixation of Coronoid Fractures in Terrible Triad Injuries: A Simple Syringe-guided Technique.

OBJECTIVE: The fixation of the coronoid fractures in terrible triad injuries is quite challenging. In this study, we introduce a minimally invasive technique using a syringe as a guide for insertion of the cannulated screw in an anterior to posterior fashion to fix the coronoid fracture in patients with terrible triad injuries. METHODS: In this retrospective study, clinical data of patients suffering from terrible triad injuries between 2012 and 2019 were analyzed. Fifteen patients with an average age of 38.2 years old (21-56 years) were enrolled in this study, of which 12 were males and three were females. The Regan-Morrey type II and type III coronoid fractures in these patients were treated with cannulated screws, inserted anteriorly using a 1 mL syringe as a guide. Outcome measures included pain, range of motion, stability and daily function using Mayo Elbow Performance scores (MEPs). The anteroposterior and lateral radiographs were used for evaluating a healing fracture. RESULTS: After a mean follow up of 44.2 months (range 13-80), the mean elbow flexion was 128.2°, extension was 12.3°, forearm pronation was 74.6° and supination was 73.6°. A concentric reduction was maintained without severe pain, stiffness, and radiographic evidence of instability in all patients during the follow-up period. The mean MEPs was 89.7 points. CONCLUSION: The anteroposterior cannulated screw fixation via simple syringe guide is a minimally invasive and safe option for surgical treatment of coronoid fractures in terrible triad injuries.

Primary closure using a perforator flap-based technique for the treatment of Dupuytren's contracture.

We aim to present a perforator flap-based technique that is useful in the resection and reconstruction of the palmar fascia for the treatment of Dupuytren's contracture with primary closure. A curve incision through the palmar skin radial to the hypothenar area was made. The ulnar side of the palmar skin and the subcutaneous fat was raised to the ulnar side, exposing the palmar fascia. The ulnar palmar digital artery extending from the superficial palmar arch curves distally towards the little finger at a point perpendicular to the fourth interdigital space with parting branches into the subcutaneous fat radial of the flap was carefully identified and preserved, and the Dupuytren's cords were excised. Depending on contracture involvement, additional incision extending from the arc of the palmar incision to the proximal interphalangeal joint is made to raise the digital flap similar to that of the palmar incision. The perforator flap was raised along the hypothenar region in 53 hands of 48 patients, nine women and 39 men, and their age at the time of surgery averaged 56 years. Two patients complained of paresthesia in the ring and little fingers after surgery in 2015, and the symptom had disappeared without further intervention before the latest follow-up in 2017. There was no incidence of skin necrosis, delayed healing, and no recurrence within the follow-up period. This perforator flap-based technique is technically reliable and straightforward with better exposure and easier removal of all the diseased fascia, making it possible for primary healing without skin necrosis and acceptable for the treatment of patients at all stages of the disease.

The efficacies and limitations of fasciectomy and collagenase clostridium histolyticum in Dupuytren's contracture management: A meta-analysis.

BACKGROUND: We intend to assess the efficacies and limitations of collagenase clostridium histolyticum (CCH) and fasciectomy in treating Dupuytren's contracture, and the associated complications and rate of recurrences aiming to present a treatment algorithm. METHODS: A literature search within the PubMed, Web of Sciences, Cochrane Library, and EMBASE databases was performed using the combined key words 'Dupuytren, palmar aponeurosis contracture, collagenase clostridium histolyticum and fasciectomy', including all possible studies with a set of predefined inclusion and exclusion criteria. RESULTS: Thirty studies were assessed for eligibility from 215 identified records. Seventeen publications satisfied the inclusion criteria including 2142 joints in 1784 patients. The mean follow-up time was 18.0 months (3-60). CONCLUSION: Acceptable contractures release was obtained in both techniques. Severe complications associated with fasciectomy outrank those of CCH, whereas the low rate of recurrence favors the fasciectomy technique.

Bilateral Locking of the Metacarpophalangeal Joint: A Case Report and Systematic Literature Review.

BACKGROUND: The purposes of this article were to present an exemplary case of bilateral locked metacarpophalangeal (MCP) joint of the second metacarpal and to review the literature for a more comprehensive understanding of this condition. METHODS: For the literature review, PubMed and Google Scholar research were performed using the term "metacarpophalangeal joint (MCP joint) locking or locked metacarpophalangeal joint (MCP Joint)" with a set of inclusion and exclusion criteria. RESULTS: We recently treated a patient with bilateral locked MCP, which presented to our office on 2 separate occasions in the space of 3 years. The left hand was affected in 2015 and the right hand in 2018. After clinical and imaging investigations, the patient was operated on. The patient had a locking of the accessory collateral ligament behind a radial sided prominence of the second metacarpal head. After surgery, the patient regained full function of her index finger. On the basis of our literature review, we found 47 cases described in the literature, plus our case, the index finger (22), and the long finger (11) were most commonly involved. CONCLUSION: Left untreated, the locked MCP joint may lead to a flexion contracture and disabilities in performing daily life activities. The diagnosis is mainly clinical. The radiographs can show degenerative changes or a particular shape of the metacarpal head/neck as a first clue to the possible cause. Gentle closed reduction can be attempted, but surgery is most often required. The surgical approach depends on the presumed localization of the pathology.
