OBJECTIVE: To explore clinical efficacy of external placement of micro-locking plate combined with small incision reduction in treating proximal phalanx comminuted fractures. METHODS: From January 2018 to December 2019, 17 patients with proximal phalanx comminuted fractures were treated with micro-locking plate combined with small incision open reduction, including 13 males and 4 females, aged from 16 to 64 years old with an average of (37.2±20.1) years old. Two patients were accompanied by soft tissue extrusion and opening injuries, which were treated with fixed treatment after the first-stage emergency debridement. Curative effect was evaluated according to total active flexion scale (TAFS) of American Hand Surgery Association at 6 months after operation;and fracture healing, nailing, local soft tissue healing, complications were observed. RESULTS: All patients were followed up from 6 to 12 months with an avaerge of(9.3±3.6) months. Two patients occurred delayed union, 1 occurred local skin necrosis and was treated with the second-stage skin grafting to repair wound surface. No external screw breakage or infection was reported, skin soft tissue healed favorably and reached bony union, the union time from 12 to 24 weeks with an average of (15.7±2.1) weeks. According to TAFS standard, 9 patients got excellent result, 5 good and 3 poor at 6 months after operation. CONCLUSION External micro-locking plate combined with small incision reduction in treating proximal phalanx comminuted fracture, which has advantages of good condition of skin and soft tissue, simple operation, early functional exercise, good range of motion of interphalanx joint, and function score of recovery period is high.

Hand fractures are the second most common fracture in the upper extremities after the distal radius, and patients with these injuries may be experienced in hand surgery clinics. On the other hand, during the treatment of hand fractures, complications can occur due to complex functions of the hand and small-sized injuries to the bone and soft tissues. This review focused on the principles of management of these fractures, including injury mechanism, evaluations and recent treatment options. Minimally invasive surgery in various types of hand fractures, including the phalanx and metacarpal bone, is preferred because early mobilization after surgery has been emphasized to reduce complications, such as stiffness.

PURPOSE: Hand fractures can be treated conservatively in many cases, but rotation malalignment is one of the important indications for surgical treatment because of dysfunction. We performed open reduction and internal fixation in these malalignment fractures and report clinical and radiological results. METHODS: This study included 28 patients (18 male, 10 female) who had metacarpal and phalangeal fractures with rotational malalignment of finger on initial examination. Patients with combined injuries including open soft tissue damage or multiple fractures were excluded. Mean age was 36.1 years and average follow-up period was 14.6 months. Perioperative extent of rotation and correction during the follow-up, union on the radiographs, Range of motion, disability of the arm, shoulder and hand (DASH) score, and pinch power at the last follow-up were evaluated. RESULTS: Average corrected angulation of rotation was 11.9° and no patient showed scissoring appearance of fingers at the last follow-up. All patients showed solid bony union on the radiographs during the follow-up. The average of total active motion of the injured fingers were average 254°, average DASH score was 3.2 and average pinch power was 3.0 kg at the last follow-up. CONCLUSION: Clinical and radiologically satisfactory results were obtained in all patients. Care should be taken not to overlook the rotational misalignment after fracture of the hand, and surgical treatment should be considered to ensure correct reduction and fixation.

OBJECTIVETo summarize the therapeutic effect of free perforator hypothenar flap for thumb pulp defect.

METHODSFrom Jun. 2012 to Mar. 2013,8 cases with thumb pulp defect accompanied with exposure of phalanges ans tendons were treated by free ipsilateral perforator hypothenar flap. The flaps were 1.4 cm x 2.0 cm-1.8 cm x 2.2 cm in size. Ulnar finger artery in the flap was anastomosed with thumb artery. The accompanied veins and superficial veins were respectively anastomosed with thumb dorsal veins. Nerve branches in flaps were sutured with unilateral finger nerve to reconstruct flap feeling with 9-0 thread. Wounds in the hypothenar donor site were sutured directly.

RESULTSAll the flaps survived completely with primary healing both in donor and recipient area. 8 cases (8 fingers) were followed up for 6-13 months (average 9 months). The flaps appearance, texture were good. The two-point discrimination distance on flap was 7-10 mm. The active and passive movement of thumb joints was normal. There was no complain about the feeling at the donor site. Linear scar was left on the donor site. Patients hand grip strength was not decreased.

CONCLUSIONSThe free perforator hypothenar flap which has constant vascular anatomy is a new method for thumb soft tissue defect with less morbidity to donor site. The operative procedures are relatively simple.

OBJECTIVETo explore therapeutic effects of minor external fixator for open comminuted phalangeal fractures with non-transarticular.

METHODSFrom January 2013 to December 2014,13 patients with open comminuted phalangeal fractures were treated by minor external fixator with non-transarticular, including 9 males and 4 females aged from 18 to 56 years old with an average of 35 years old. According to Gustilo classification, 8 cases were type II, and 5 cases were type III. The time from injury to operation ranged from 2 to 7 h averaged 5 h. Seven patients were diagnosed as phalangeal fracture, 6 patients were involved with joint surface of phalangeal, which 1 case combined with inherent nerve damage and 1 case combined with soft tissue defect repaired at stage II. The patients were fixed by plaster for 2 weeks and removal external fixtor from 6 to 8 weeks after operation and received functional exercise.

RESULTSAll patients were followed up from 3 to 12 months with an average of 7 months. One case occurred metacarpophalangeal joints stiffness. No screw breakage, inflammation occurred. Skin soft tissue recovered well and obtained bone healing, the average time of bone healing was (4.6 ± 1.0) weeks. According to TAM scoring system used by Hand Surery Association of Chinese Medical Association, 7 cases got excellent results, 4 good, 1 moderate and 1 poor.

CONCLUSIONMinor external fixator for open comminuted phalangeal fractures with non-transarticular has advantages of simple operation, good stability, and could adjust at the later stage, less damage for soft tissue periosteum, low inflammatory rate, earlier functional exercise. It is worth to be popularized and applied.

OBJECTIVETo study the classification and individualized treatment of the terminal phalanx of thumb duplication.

METHODSFrom Apr. 2003 to Dec. 2012, 76 patients with 77 involved thumbs duplication at the level which is distal to the interphalangeal joint were retrospectively studied. Based on the morphology (the nail width and the thumb circumference) and the deviation of the thumb, we classified the terminal phalanx of thumb duplication into 5 types as Type A (no bony connection called floating thumb), Type B(asymmetry and no deviation), Type C(asymmetry and deviation), Type D (symmetry and no deviation) and Type E(symmetry and deviation). Different surgical procedures were selected according to different types. Simple excision of the smaller thumb was adopted for Type A case. Removement of the smaller thumb (usually the radial) and of the collateral ligament of the interphalangeal joint were selected for Type B. Removement of the smaller thumb (usually the radial) and reconstruction of the collateral ligament of the interphalangeal joint, as well as corrective osteotomies at the neck of the proximal phalanx were performed for Type C. The modified Bilhaut-Cloquet procedure with reconstruction of the collateral ligament of the interphalangeal joint were adopted in Type D. The classical Bilhaut-Cloquet procedure, or the modified Bilhaut-Cloquet procedure with reconstruction of the collateral ligament of the interphalangeal joint and corrective osteotomies at the neck of the proximal phalanx were performed in Type E. The results were assessed by an evaluation form for thumb duplication by the Japanese Society for Surgery of the Hand.

RESULTSAccording to our new classification standard, there were 3 cases with Type A duplicated thumbs, 36 with Type B, 13 with Type C, 15 with Type D, 10 with Type E. All the 76 patients underwent the individualized surgical treatment. The patients were followed up for 6-60 months. According to the evaluation form, excellent results were achieved in 66 thumbs, good in 9 thumbs and fair in 2 thumbs.

CONCLUSIONSThe new classification could comprehensively describe the clinical features of the terminal phalanx of congenital thumb duplication. Individualized therapy, including basic and repeated surgical procedure could be adopted for each type with satisfactory results.

Sheldon-Hall syndrome (SHS) is a rare autosomal dominant, inherited arthrogryposis syndrome characterized by multiple congenital contractures of the distal limbs. To date, four genes that encode the skeletal muscle fiber complex have been confirmed as the causative genes. Mutations in MYH3 have been identified most frequently and few cases of SHS caused by TPM2 mutations have been reported worldwide. This report describes, for the first time, a Korean family with two generations of SHS resulting from a rare TPM2 mutation, p.R133W. The affected mother and daughter manifested typical facial features of SHS including a triangular face with downslanting palpebral fissures, small mouth, high arched palate, and prominent nasolabial folds, and showed camptodactyly of fingers and deformities of feet with congenital vertical tali. Generalized myopathy with relative sparing of the slow-twitch muscle fibers was also revealed by electromyography in the affected mother.

Phalangeal neck fractures occur almost exclusively in children. We present the case of a 49 years old man with a dislocated fracture of the neck of the middle phalanx with the distal fragment rotated at 180? due to a traumatic circular saw injury to the left index, which was solved by anatomical reduction and bone fixation with two 1.5 mm Synthes screws and a temporary transarticular K-wire at the distal interphalangeal joint. Zone I flexor digitorum profundus repair was performed using a modification of the Kessler 4-strands core suture and a full-thickness skin graft from the hypothenar eminence was taken to cover the skin gap. At 6-month follow-up the patient was pain-free and with a total active movement equivalent to 190? No radiological signs of avascular necrosis of the head of the middle phalanx or nonunion of the distal fragment was detectable with recovery to the previous manual work. Owing to the position of the phalangeal head maintained in position by the collateral ligaments an anatomic reduction from dorsal approach is difficult to be performed and a longitudinal traction can render the reduction harder too. The volar approach permits an easier reduction of the fracture through a derotation of the distal fragment facing palmar.

OBJECTIVE: To study the characteristics of forensic identification of phalangeal fracture and to use a combination of medical records, imaging materials, and forensic examination data in identification. METHODS: Fifty cases of phalangeal fracture involved in the forensic identification were collected from 2009 to 2011. The general situation, the distribution of fracture, the fracture morphology, the injury-causing objects and the results of identification were analyzed retrospectively. RESULTS: Majority of the cases of phalangeal fracture were young and middle-aged men. The index finger and distal phalanx fractures were common. There was no difference in the number of phalangeal fracture between left and right hand. Most of the injury-causing objects were knives and sticks, followed by bricks and stones. CONCLUSION The injury-causing objects and modes are related to the morphology of fracture, the distribution of fracture and the severity of the injury. The comprehensive analysis is helpful in forensic identification of phalangeal fracture.
