Infection of finger caused by Morganella morganii leading to digital amputation: A case report.

RATIONALE: Digital infection is a common disease in clinic, featured by pain and swelling of digits. As far as we know, no article has reported a case of digital infected by Morganella morganii. PATIENT CONCERNS: A 58-year-old Chinese female complains about whitlow with pain and swelling for 2 weeks. She has a history of diabetes for 10 years. She received incision and drainage before coming to our hospital and preoperative X-ray of left ring finger presented no bone eroded. DIAGNOSIS: She is diagnosed with infection of ring finger caused by M morganii in our hospital. INTERVENTIONS: We perform aggressive operative debridement and drainage firstly. Meanwhile, we provide tissue samples for diagnosis and the result indicates M morganii infection. Then, she is treated with anti-infection therapy and regulation of diabetes. However, 1 week after first surgery, her condition deteriorate presenting bone erosion in distal phalanx of ring finger from X-ray. Considering severity of illness, we decide to perform digital amputation. OUTCOMES: At 3-month follow-up, the patient has a satisfactory result and X-ray shows no bone eroded. LESSONS: Clinicians should consider M morganii, which is rare in hand infection, as a cause of digital infection. This case reminds us that some whitlow is dangerous, amputation should be considered if necessary.

Modified trapeziectomy with ligament reconstruction tendon interposition for the treatment of advanced thumb carpometacarpal arthritis: A case report.

RATIONALE: Thumb carpometacarpal (CMC) arthritis is a common disease. Various procedures have been described for the treatment of advanced thumb CMC arthritis. This essay shows a CMC arthritis case treated by modified trapeziectomy with ligament reconstruction tendon interposition (LRTI). PATIENT CONCERNS: A 53-year-old Chinese female complained of pain and swelling at the base of the left thumb for 10 years. Visual analog scale (VAS) for thumb was 7 points, Disabilities of Arm, Shoulder and Hand (DASH) score was 51 points, and Kapandji score was 6 points before surgery. Preoperative range of motion (ROM) for radial abduction and volar abduction were 63°and 62°, respectively. Grip power was 15.3 kg and key-pinch power was 1.8 kg before operation. Preoperative waist flexion power was 20.9 kg. Hand x-ray showed left thumb CMC arthritis in Eaton stage III and the height of the trapezial space was 10 mm. DIAGNOSES: She was diagnosed with left thumb CMC arthritis (Eaton III stage). INTERVENTIONS: The patient underwent modified trapeziectomy with LRTI. After exposing and removing trapezium, and a hole from the dorsal base to the center of the articular surface was drilled. Then we cut the whole flexor carpi radialis and divided it into 2 halves. Afterward, we passed one-half through the hole and tied it to the other part and sutured them. The rest tendon was then tied continuously and sutured. Then we rolled it up into the space where previous trapezium was located. OUTCOMES: Two years after operation, pain and swelling relieved and no recurrence of the clinical symptoms occurred. VAS, DASH, and Kapandji score were 2, 22, 7 points, respectively. ROM for radial abduction and volar abduction were 79° and 78°, respectively. Furthermore, grip power was 22.7 kg and key-pinch power was 3.8 kg. Waist flexion power was 20.0 kg. Hand x-ray showed that the height of the trapezial space was 9.8 mm. LESSONS: Modified trapeziectomy with LRTI in treatment of advanced thumb CMC arthritis had a satisfactory efficacy. This new procedure not only prevents thumb sinking, but also provides enough support for thumb.
