We present the technical report for treatment of comminuted fracture of the capitate with ligamentotaxis. The base of third metacarpal was found to be fractured with comminution of the capitate. The decrease in carpal height index and comminution of the third metacarpal base lead to dilemma between conservative treatment and surgical management of this particular injury. The surgical management was chosen to maintain the carpal height index of the wrist to prevent the late degenerative changes.The patient was applied with external fixator in distraction mode expanning the wrist joint for six weeks, and the wrist was mobilised after removal of the fixator. It is shown that the external fixator in distraction mode expanning the wrist joint is a good alternative method for treatment of capitate fracture.

OBJECTIVETo investigate the application of the dorsal metacarpal perforator sliding flap for web-space reconstruction in congenital syndactyly.

METHODSAccording to the size and shape of skin defect at the web space after division operation of syndactyly, the corresponding intermetacarpal perforator sliding flap was designed. The edge of the flap was cut off, but its underlying tissue was not dissected. From May 2007 to November 2012, 28 web-spaces in 15 patients with syndactyly (10 male and 5 female) were reconstructed.

RESULTSAll the 28 flaps survived completely. The flap size ranged from 3 cm x 2 cm to 1.5 cm x 1.0 cm. 14 cases with 26 flaps were followed up for 10-22 months (average, 14.5 month). The reconstructed web spaces had normal appearance and movement range. The 2-point discrimination distance was 9-13 mm (average, 11 mm). According to the Swanson Standard, 18 fingers were graded as excellent, 8 as good and 2 as fair (excellent and good, 92.6%, 26/28).

CONCLUSIONSReconstruction of web-space in syndactyly with the dorsal metacarpal perforator flap has the advantages of easy handling, good cosmetic and functional results.

Double fracture-dislocations of the thumb are rare. Only a single case report of a simultaneous extra- articular fracture of the base of the first metacarpal and dislocation of the metacarpophalangeal joint has been previously reported. We report the second case report of this injury in a 20-year-old man. The patient had an excellent outcome after treatment.

OBJECTIVE: To compare the clinical efficacy of micro steel plate and Kirschner needle oblique and transverse internal fixation of adjacent metacarpal bone in the treatment of metacarpal diaphyseal oblique fracture. METHODS: Fifty-nine patients with metacarpal diaphyseal oblique fractures admitted between January 2018 and September 2021 were selected as the study subjects and divided into the observation group (29 cases) and the control group (30 cases) based on different internal fixation methods. The observation group was treated with Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones, while the control group was treated with micro steel plate internal fixation. Postoperative complications, operation time, incision length, fracture healing time, treatment cost, and metacarpophalangeal function were compared between the two groups. RESULTS: No incision or Kirschner wire infections occurred in the 59 patients, except for one in the observation group. No fixation loosening, rupture, or loss of fracture reduction occurred in any of the patients. The operation time and incision length in the observation group were (20.5±4.2) min and (1.6±0.2) cm, respectively, which were significantly shorter than those in the control group (30.8±5.6) min and (4.3±0.8) cm (P<0.05). The treatment cost and fracture healing time in the observation group were (3 804.5±300.8) yuan and (7.2±1.1) weeks, respectively, which were significantly lower than those in the control group (9 906.9±860.6) yuan and (9.3±1.7) weeks (P<0.05). The excellent and good rate of metacarpophalangeal joint function in the observation group was significantly higher than that in the control group at 1, 2, and 3 months after operation (P<0.05), but there was no significant difference between the two groups at 6 months after operation (P>0.05). CONCLUSION Micro steel plate internal fixation and Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones are both viable surgical methods for treating metacarpal diaphyseal oblique fractures. However, the latter has the advantages of causing less surgical trauma, shorter operation time, better fracture healing, lower cost of fixation materials, and no need for secondary incision and removal of internal fixation.

OBJECTIVETo introduce a method by reversed ulnar fasciocutaneous flap incised form the ulnar side of the fifth metacarpal area for repairing the soft tissue defect of the fifth finger.

METHODSFrom May 2001 to September 2001, ten patients with the soft tissue defects of the thenar side, dorsal side or ulnar side of the fifth finger were treated with the reversed ulnar fasciocutaneous flap incised from the fifth metacarpal area. The axial line of the flap was the line from ulnar side of the head of the fifth metacarpal bone to the pisiform level. The revolving point of the flap pedicle was 0.5-1 cm near the proximal end of the metacarpal-phalangeal joint.The area of the flap was form 5.0 cm x 3.5 cm to 1.5 cm x 1.0 cm.

RESULTSAll flaps of the ten cases were alive. 5-7 months followed-up show that, after operation, the flap present sensation in 6-12 mm, with soft texture and good appearances.

CONCLUSIONSThe advantages of this operative method were as follows: the reversed ulnar fasciocutaneous flap of the fifth metacarpal area have reliable blood supply, it was easily dissected and with good texture. So far this kind of flap is a good choice in repairing the soft tissue of the fifth finger.

BACKGROUNDTo avoid the irritation of tendons and soft tissues as well as hardware-related problems, we designed an intramedullary fixation with bioabsorbable rods for the treatment of the metacarpal shaft fractures.

METHODSFive patients with nine shaft fractures of the fourth and fifth metacarpi were treated with intramedullary absorbable implants and followed up with an average of 4.2 months postoperatively.

RESULTSAt final follow-up, all patients achieved fracture union with no signs of inflammatory or subcutaneous effusion. There was no shortening, angulatory, or rotatory deformity. There was almost full active extension range of motion (ROM) of the metacarpophalangeal joints while the active flexion ROM of these joints was 80.7 ± 9.6°. Compared with the contralateral hand, the grip strength of the injured hand was 94.0 ± 9.6%. X-rays showed that the arch of the second to fifth metacarpal heads was smooth. There were no intramedullary lytic changes and soft tissue swellings.

CONCLUSIONThe intramedullary absorbable implants are a safe, simple, and practical treatment for fourth and fifth metacarpal fractures with good early clinical outcomes and no significant complications.

OBJECTIVETo compare the clinical outcomes between two different methods in the treatment of Bennett fractures.

METHODSFrom May 2005 to June 2009, 31 patients with Bennett fractures were treated with gypsum and percutaneous fragment pin fixation. In gypsum fixation group,there were 17 cases including 12 males and 5 females with an average age of (43.9-5.7) years; according to Buechler classification: 3 cases were I region fracture, 11 cases were II region fracture, 3 cases were III region fracture. In percutaneous fragment pin fixation group,there were 14 cases including 8 males and 6 females with an average age of (45.6 +/- 6.1) years; according to Buechler classification: 3 cases were I region fracture, 9 cases were II region fracture and 2 cases were II region fracture. The observing and comparing items of the two groups included: (1) length of stay, time of fracture healing,failure of fixation; (2) postoperative radiographs comparison according to method of Kjaer-Petersen; (3) cannon scores used for outcome measurement.

RESULTSAll the patients in the two groups were followed up, the duration ranged from 6 to 15 months,with an average of (9.0 +/- 3.5) months. The length of stay were (7.0 +/- 2.5) d in gypsum fixation group and (9.0 +/- 3.9) d in percutaneous fragment pin fixation group with statistically significant differences (P < 0.05). The postoperative reduction quality according to method of Kjaer-Petersen, in gypsum fixation group:4 patients got an excellent result, 8 good and 5 poor; in percutaneous fragment pin fixation group,the above data were 8, 6 and 0 respectively;there were statistically significant differences (P < 0.05 ) between the two groups. The time of fracture healing were (6.0 +/- 0.5) weeks in gypsum fixation group and (6.0 +/- 1.9) weeks in percutaneous fragment pin fixation group with no statistically significant differences (P > 0.05). Cannon scores were evaluated at postoperative 3 months,in gypsum fixation group: 6 patients got an excellent result, 8 good and 3 fair; in percutaneous fragment pin fixation group,the above data were 8, 5 and 1 respectively; there were no statistically significant differences (P > 0.05) between two groups. Two patients had fracture re-displacement in gypsum fixation group, and no failure cases in percutaneous fragment pin fixation group.

CONCLUSIONThere are satisfied therapeutic effects in two different methods for the treatment of Bennett fractures. However, gypsum fixation has advantage of easy to operate and atraumatic, but unstability and easy to displacement; percutaneous fragment pin fixation has advantage of fixed solidly and better in functional rehabilitation, but big in surgical trauma and long in length of stay.
