Objective:To investigate the effect of chimeric flap pedicled with superficial branch of superficial iliac circumflex artery in repair of soft tissue defect of dorsal hand combined with metacarpal bone defect.Methods:From May 2015 to January 2022, 34 patients(28 males and 6 females) of soft tissue defects of dorsal hand with metacarpal bone defects were treated in the Department of Orthopedics of Yibin Third People's Hospital. The age of patients ranged from 22 to 51 years old, with an average age of 37 years old. The areas of soft tissue defects after debridement were 2.5 cm×5.0 cm-4.5 cm×9.0 cm, and the defects were all in dorsal hand and dorsal wrist. The lengths of metacarpal bone defect were 1.8-4.1 cm. All the patients had only single metacarpal bone defect, among which: 14 patients had defects in first metacarpal bone, 7 in second metacarpal bone, 4 in third metacarpal bone, 8 in fourth metacarpal bone and 1 in fifth metacarpal bone. All the patients were repaired by chimeric flap pedicled with superficial branch of superficial iliac circumflex artery. The size of flaps were 3.6 cm×5.4 cm-5.2 cm×9.5 cm. Anticoagulation, thermal preservation and plaster fixation were applied for 4-6 weeks after surgery. Postoperative follow-ups included regularly outpatient clinic visit, telephone or Wechat reviews. Follow-up items covered: the feeling and appearance of flaps in recipient sites, healing of the donor sites and recovery of hand functions.Results:All the 34 chimeric flaps survived. Regular follow-up lasted for 3 to 15(average, 10) months. All incisions in the donor sites of hip healed in stage I. TPD of the flaps was 5.1-7.3(mean, 6.4) mm. Appearance of flaps in the receiving area were satisfactory without swelling. Movement of wrists and metacarpophalangeal joints met the basic requirement of movement. The healing time of metacarpal defect was 2-3 months with an average of 2.8 months. Hand functions were evaluated at excellent in 6 patients and good in 28, according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Conclusion:The chimeric flap pedicled with superficial branch of superficial iliac circumflex artery is an ideal flap to repair the soft tissue defect in dorsal hand combined with metacarpal bone defect. It has advantages of less donor site damage, good blood supply of flap, simple surgical procedure, and one-stage repair of a combined soft tissue and metacarpal bone defects.

Radiologic Prevalence and Features of Metacarpal Pseudoepiphysis on Normal Korean Children / 대한정형외과학회잡지

PURPOSE: Pseudoepiphysis originates from the secondary ossification center of the non-ossification end during the normal pediatric growth process. It is not uncommonly found in the course of metacarpal and metatarsal ossification. We investigated the radiologic prevalence and features of pseudoepiphysis in normal Korean children. MATERIALS AND METHODS: Sex and age distribution following radiologic prevalence as well as the features of metacarpal pseudoepiphysis of 2,320 Korean children aged below 15 years of age and younger who underwent hand radiography between January 2009 and February 2016 were analyzed. RESULTS: A total of 304 out of 2,320 patients had pseudoepiphysis on metacarpal bone, which is a prevalence of 13.1%. Male showed higher prevalence (16.6% for male and 10.5% for female). The peak age was 11 years for boys and 5 years for girls. The first metacarpal bone was most prevalent, with 9.6% of the total population, followed by the second metacarpal bone (5.2%) and fifth metacarpal bone (2.5%). The prevalence of single pseudoepiphysis was 9.4%, and that of multiple pseudoepiphysis was 3.7%. The prevalence of incomplete pseudoepiphysis was 8.9% and was higher than complete pseudoepiphysis (5.6%). CONCLUSION: The prevalence of metacarpal pseudoepiphysis in normal Korean children was 13.1%. It is necessary to be aware of the radiologic features and distributions of pseudoepiphysis to avoid misinterpretation as a bone disease or traumatic fracture in pediatric patients.

Double locking mini-plates for fixation of comminuted fracture of the first metacarpal base / 中华创伤骨科杂志

Objective To investigate the clinical efficacy of double locking mini-plates for fixation of the comminuted fracture of the first metacarpal base.Methods Twenty-four patients with the comminuted fracture of the first metacarpal base were treated by double locking mini-plates in our hospital from January 2013 to January 2016.They were 17 males and 7 females,from 27 to 65 years of age (average,33.5 years).By the Green classification,6 cases were type Ⅰ,13 cases type Ⅱ and 5 cases type Ⅲ.All the fractures were closed.The average time from injury to surgery was 2.3 days (from 8 hours to 7 days).After open reduction via the palmar-radial incision,the fracture was fixated with 2 mini-plates,one locking T-plate on the radial side and one straight locking plate on the dorsal side.Fracture healing time,pain and finger function were followed up postoperatively.Visual analogue scale (VAS) was used to evaluate the pain at 12 months and scoring for digital total range of motion to assess the function of the affected finger at the final follow-up.Results The 24 patients obtained follow-up for 8 to 28 months (average,18 months).All the Fractures healed after 9 to 12 weeks (average,10.5 weeks).The VAS scores at 12 months ranged from 0 to 3 (average,1.5).The function of the affected finger at the final follow-up was excellent in 20 cases and good in 4,giving an excellent to good rate of 100％.Two patients complained of pain after frequent motion of the finger.No complications like skin problems,dislocation of the first metacarpal base,implant failure,necrosis or irritation of the soft tissue were observed during follow-up.No angulation or rotational deformity occurred after fracture union.Conclusion Fixation with double locking mini-plates can effectively treat comminuted fractures of the first metacarpal base,because it can provide rigid stabilization which promotes early functional exercise of the finger,and prevents joint stiffness as well.

Resection of Thumb Metacarpal Ewing Sarcoma and Primary Reconstruction with Non-Vascularized Osteoarticular Metatarsal Autograft

Ewing sarcoma is a primary bone malignancy that rarely occurs in the hand. Resection and reconstruction will usually result in reduced or loss of thumb function. We describe a case of successful transplantation of nonvascularized osteoarticular second metatarsal autograft following wide resection of Ewing sarcoma of first metacarpal in an 11-year-old girl. The capsule of the graft’s metatarso-phalangeal joint was repaired to achieve mobility of the joint. This enabled preservation of thumb function by a relatively simple surgical technique. Detailed surgical procedures and excellence function after 2 years following surgery are described.

Treatment of 5th Metacarpal Neck Fracture Using Percutaneous Transverse Fixation with K-Wires

PURPOSE: To evaluate the radiologic and clinical results of percutaneous transverse fixation with K-wires for 5th metacarpal neck fracture. MATERIALS AND METHODS: Between January 2007 and September 2010, 18 patients with a 5th metacarpal neck fracture, who underwent operative treatment, were included in this study. The surgical method was percutaneous transverse fixation using K-wires. We evaluated fracture angulation in oblique radiographs preoperatively, postoperatively, and at final follow-up, and used SPSS to perform statistical analysis. We also performed clinical evaluation using the Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: All of the 18 cases were completely united, and in the oblique radiographs, the angulation was corrected from 50.69degrees to 11.68degrees. The average difference between postoperative and final follow-up angulations was 0.14degrees, which was statistically insignificant. Clinically, the DASH score was 1.030 and no complications were observed. CONCLUSION: Percutaneous transverse fixation using K-wires could be one of the best ways to treat a 5th metacarpal neck fracture because of its simple method and low rate of complications.

Exame clínico e radiológico do terceiro metacarpeano em potros Puro Sangue de Corrida em treinamento / Clinical and radiographic evaluation of the third metacarpal bone in 2-year-old thoroughbred horses in raining

A avaliação clínica e radiológica do terceiro metacarpeano (McIII) de 42 potros Puro Sangue de Corrida de dois anos de idade, em treinamento, realizou-se a cada 15 dias. Vinte e cinco potros foram acompanhados durante dois meses e 17 durante os quatro meses anteriores a sua participação na primeira corrida. Nas radiografias (projeção lateromedial), foram avaliadas o córtex dorsal (CD) do McIII e a espessura do CD, do córtex palmar e da zona medular para determinação do índice radiológico (IR). Não foram observadas alterações radiológicas no CD do McIII nos potros que manifestaram periostite metacarpeana dorsal (PM) aguda. O aumento tanto do CD, como do IR, entre as avaliações foi significativo (P<0,05). Porém, apenas a diferença de espessura do CD entre os McIII sem alterações e os que manifestaram PM foi significativa (P<0,05). O aumento mais acentuado do CD foi observado sempre na avaliação anterior àquela em que foram detectados os sinais clínicos de PM. Portanto, especialmente a mensuração do CD pode ser utilizada como um método diagnóstico precoce de PM, permitindo a sua prevenção.

The third metacarpal bones (McIII) of 42 2-year-old thoroughbreds in training were evaluated clinically and radiologically every 15 days. The evaluation was performed during 2 and 4 month, prior to the first race of 25 and17 horses, respectively. X-rays were taken using latero-medial projection. Dorsal cortex (DC) was evaluated on the X-rays and DC, palmar cortex and medular zone were measured in order to determine the radiologic index (RI). No radiographic changes were observed on the DC of the McIII of horses clinically affected by dorsal metacarpal disease (DMD). There was a significant increase (P<0.05) in DC thickness and RI between evaluations of both, healthy and DMD affected McIII. DC thickness also showed a significant increase between affected and not affected McIII. A larger increase in DC thickness was observed at evaluation before the one in which DMD was diagnosed. In conclusion, the increase in DC thickness could be used as a diagnostic tool for early recognition of DMD allowing adoption of preventive measures.

Bouquet Pin Intramedullary Nail Technique of the 5th Metacarpal Neck Fractures

PURPOSE: To evaluate radiologic and clinical results of bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture. MATERIALS AND METHODS: Between April, 2005 and February, 2006, 17 patients treated by bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture were evaluated. All patients were reviewed clinically and radiologically after operation. RESULTS: All of 17 cases of fractures were completely united. In the anteroposterior radiographs, the average of preoperative angulation was corrected from 34.4° to 5.2°. Also, in the oblique radiographs, radiographic results of angulation correction were satisfactory which was corrected from 44.2° to 11.7°. Although, the averages of difference between postoperative and final follow-up angulations were 1.5° in the anteroposterior radiographs and 0.9° in the oblique radiographs, they were not statistically different. All patients were excellent clinically except 1 patient who has moderate joint stiffness after operation. CONCLUSION: Selecting of appropriate patients who is indicated, bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture could be a good treatment method without complications.

Fractures of the Wrist and Hand after Punching Injury / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to describe the patterns and results of treatment of fractures of the hand and wrist after punching injury. MATERIALS AND METHODS: The authors retrospectively reviewed 91cases of fractures of the hand and wrist after punching injury in 67 patients from January 1998 to September 2002. The mean follow-up was 18 months. The mean age was 25.7 years old, ranging from 11 years old to 41 years old. The results were evaluated by modified criteria of Bruce and Maudsley. RESULTS: The most common fractures were metacarpal base fractures (42.9%), and the second most common fractures were distal metacarpal fractures (19.8%). Metacarpal base fractures were usually combined with dislocation of carpometacarpal joint, especially in the fourth and fifth metacarpal bone and single fifth metacarpal bone (29.7%). There were a few complications of limitation of motion (4 cases), pain (1 case), angular deformity of distal metacarpal bone (1 case), malunion of metacarpal shaft (2 cases) and nonunion of metacarpal shaft (1 case). There were excellent results in 84 cases, good in 4 cases and fair in 3 cases. CONCLUSION: The most common fractures after punching injury were metacarpal base fractures, especially the forth and fifth metacarpal bone. Distal metacarpal and metacarpal shaft fractures were mostly single fractures. There were diverse patterns of fracture-dislocation of the hand and wrist after punching. We must be careful to evaluate combined injury when a patient visits after punching injury.
