Purpose: Rupture of a collateral ligament of the metacarpophalangeal joint is rare except in the thumb. The injured digit became flexed and deviated toward ulna side by the hypothenar intrinsic musculature. Incomplete rupture of a collateral ligament of the metacarpophalangeal joint can be often managed by splinting the affected digit in flexion position, however, in the case of complete tears that distraction of the ends of the ruptured collateral ligament is too great to allow repositioning by splinting. Primary repair of the ruptured collateral ligament or reattachment to bone by a pull-out wire, or tendon graft technique appears to be adequate. Methods: We report a case of instability of fifth metacarpophalangeal joint due to complete rupture of radial collateral ligament. This 18-year-old male presented pain in his right outstretched hand after trauma. The diagnosis was obtained by physical examination and simple radiography. Because of persistent instability after the initial conservative treatment, open reduction and repair surgical treatment was required. Results: The fifth metacarpophalangeal joint became free of pain and stable under forced lateral deviation. Postoperative results showed good metacarpophalangeal joint function and stability during 8 months follow-up period. Conclusion: Because of the interposition of the sagittal band between the ruptured ends of radial collateral ligament such as Stener-like lesion of the thumb, surgical repair of metacarpophalangeal joint collateral ligament of the finger was justified in case of complete laxity in full flexion.

Objectives : To treat the progression of fibroproliferative disease that affects the flexion contracture of the fingers for patients with Dupuytren's contracture, the purpose of this study is to report a case of a patient with Dupuytren's contracture after complex Korean medical treatment. Methods : A patient was treated with acupuncture, moxibustion and bee venom pharmacopuncture on their left palmar aponeurosis. Six rounds of acupuncture and moxibustion were administered from November 30, 2015 through to January 2, 2016. Three rounds of bee venom pharmacopuncture was administered from December 14, 2015 through to January 2, 2016. The degree of flexion contracture and the Tubiana's stage were measured to evaluate the clinical improvement. Results : After 30 treatment sessions the flexion contracture degrees of the 4th finger's metacarpophalangeal joint and proximal interphalangeal joint improved as much as $25^{\circ}$, $15^{\circ}$, respectively. And the flexion contracture degrees of the 5th finger's metacarpophalangeal joint, proximal interphalangeal joint and distal interphalangeal joint improved as much as $15^{\circ}$, $10^{\circ}$, $5^{\circ}$, respectively. The Tubiana's stage of each finger decreased from 4 to 3. Conclusion : This study suggests that acupuncture, moxibustion and bee venom pharmacopuncture could be effective for patients with Dupuytren's contracture.

For an effective acupuncture treatment, the location of muscles around Sutaeumkyongkun and Suyangmyongkyongkun were researched and they were made contracted. The conclusion is as follows; 1. The contraction of muscles around Sutaeumkyongkun gives appearance of the postures ; free movement of thumb, abduction of extension of wrist, flexion and pronation of elbow, depression and abduction of girdle of superior limb, flexion, internal rotation and horizontal flexion of shoulder joint These postures all together consequently produces the action 'holding something in arms'. 2. The contraction of muscles around Suyangmyongkyongkun gives appearance of the postures; extension of metacarpophalangeal and interphalangeal joint of index finger extension and abduction of thumb, extension of wrist, extension and supination of elbow, adduction, elevation and upward rotation of girdle of superior limb, extension, abduction, adduction, internal rotation, external rotation, horizontal extension of shoulder joint, flexion and opposite rotation of neck. These postures all together consequently produces the action 'raising arms'.

Background: Physical exercise is known to cause significant joint changes. Thus, monitoring joint behavior of athletic horses is essential in early disorders recognition, allowing the proper management. Objectives: The aims of this study were to determine the morphological patterns, physical examination characteristics and ultrasound findings of show jumping horses in training and to establish a score-based examination model for physical and ultrasound follow-ups of metacarpophalangeal joint changes in these animals. Methods: A total of 52 metacarpophalangeal joints from 26 horses who were initially in the taming stage were evaluated, and the horses' athletic progression was monitored. The horses were evaluated by a physical examination and by B-mode and Doppler-mode ultrasound examinations, starting at time zero (T0), which occurred concomitantly with the beginning of training, and every 3 months thereafter for a follow-up period of 18 months. Results: The standardized examination model revealed an increase in the maximum joint flexion angles and higher scores on the physical and ultrasound examinations after scoring was performed by predefined assessment tools, especially between 3 and 6 months of evaluation, which was immediately after the horses started more intense training. The lameness score and the ultrasound examination score were slightly higher at the end of the study. Conclusions: The observed results were probably caused by the implementation of a training regimen and joint adaptation to physical conditioning. The joints most likely undergo a pre-osteoarthritic period due to work overload, which can manifest in a consistent or adaptive manner, as observed during this study. Thus, continuous monitoring of young athlete horses by physical and ultrasound examinations that can be scored is essential.

The purpose of this study was to define more precisely the anatomy of the thumb flexor pulley system and to determine the relative contribution of each of the pulleys to the biomechanics of thumb motion at the metacarpophalangeal (MP) and interphalangeal (IP) joints. For this, 22 hands from 11 cadavers were used and randomly assigned to two groups. In the first group, the first annular (A1) pulley was cut first followed by the variable annular (Av) pulley and then the oblique pulley. In the second group, the oblique pulley was cut first followed by the, pulley and then the Av pulley. In 7 of 22 hands, it was a transverse structure parallel to the, pulley with a gap between the A1 and Av pulleys, referred to here as type I. In 9 hands, the A1 and Av pulleys were connected without any gap (type II). In 6 hands, the space between the A1 and Av pulleys were triangular in shape with fibers of the Av pulley converging toward the radial side (type III). In biomechanical study of both first and second experiments, there was no significant difference in MCP joint flexion between the all intact, A1 section, A1/Av section, A2 intact (A1/Av/oblique section), and no pulley configuration (p>.05). In occurring displacements less than 10 mm, there was no significant difference in IP joint flexion (p>.05). However, there was a significant decrease in IP joint flexion occurred in both 15 mm and 20 mm excursion (p<.05), when the oblique pulley was resected additionally after cutting the A1 and Av pulleys in first experiment, and when the A1 pulley was resected additionally after cutting the oblique pulley. According to the results, the injury of only the oblique pulley does not decrease thumb motion significantly. The oblique pulley injury with both the A1 and Av pulleys laceration decreased thumb motion significantly. The additional laceration of the A2 pulley does not decrease thumb motion.

Purpose: Many causes for triggering or locking of the fingers have been discussed in other literatures. The most common one is known stenosing tenosynovitis, which causes, a mismatch between the volume of the flexor tendon sheath and its contents. However, repeated trauma to the hand is uncommon cause of trigger finger. Therefore, we present a case of a rare condition of stenosing tenosynovitis which developed from a repeated relatively weak superficial flexor tendon injury. Methods: The patient was a 62-year-old woman who showed a painless, fixed and round mass on her right hand with no particular cause. Active and passive range of motion of the metacarpophalangeal joint of long finger was limited in flexion and extension. Ultrasonographic finding showed injured flexor digitorum superficialis tendon had fibrillar architecture with swelling between hyperechoic synovial membrane and hypoechoic surrounding area. Surgical exploration revealed that a bunched portion of the flexor digitorum superficialis and A1 pulley cause triggering during operation after adhesiolysis of scar tissue. Results: After releasing the A1 pulley, the range of motion of the metacarpophalangeal joint of long finger showed no limitation and histological examination of the subcutaneous tissue revealed fibrous fatty degeneration. In this case, releasing the A1 pulley with adhesiolysis of the subcutaneous scar tissue was successful and we obtained good functional outcome. Conclusion: We examined a patient in whom a repetitive impact forces to the palm caused longitudinal tear of the flexor tendon, leading to trigger finger. We experienced a rare case of stenosing tenosynovitis and trigger finger caused after close injury to flexor digitorum superficialis and its degenerative changes that caused mass like effect. To the best of authors' knowledge, our case of close injury to the flexor digitorum superficialis and unique morphologic change before rupture of tendon is rarely to be reported.

In 1980 Morrison and O'Brien reported their experiences about the reconstruction of amputated thumb using wrap-around neurovascular free flap from the great toe with a nonvascularized iliac bone graft. From then it has been considered to be a good reconstructive procedure for the amputated thumb, but it's indication has been limited distal to the metacarpophalangeal(MP) joint. We have performed 37 cases of wrap-around free flap from the great toe for the reconstruction of thumb amputated at distal or proximal to the MP joint and investigated their functional results according to the level of amputation. Level of amputation was distal to the MP joint in 25 cases and proximal to it in 12 cases. Pinching and grasping power, two point discrimination and the amount of opposition to the other fingers were compared to the uninjured hand. Pinching and grasping power were not significantly different according to the level of amputation but the amount of two point discrimination was significantly high in the cases amputated proximal to the MP joint. The opposition of reconstructed thumb to the other fingers was completely possible in all cases amputated distal to the MP joint. In 12 cases amputated proximal to the MP joint of the thumb, opposition was completely possible in 6 cases in which the iliac bone block was fixated in the position of $30^{\circ}$ flexion and $45^{\circ}$ internal rotation but in 6 cases in the fixation of $30^{\circ}$ flexion and $30^{\circ}$ internal rotation, the opposition of reconstructed thumb to the ring and little fingers were impossible in 5 cases and only to the little finger in 1 case. In this study, we concluded that even if amputation proximal to the MP joint, it is no more contraindication of the wrap-around free flap procedure for thumb reconstruction, however in these cases we recommend iliac bone block fixation in the position of $30^{\circ}$ flexion and $45^{\circ}$ infernal rotation for the better functional outcome.

Background For volar soft tissue defects of the proximal interphalangeal (PIP) joint, free flaps are technically challenging, but have more esthetic and functional advantages than local or distant flaps. In this study, we compared the long-term surgical outcomes of arterial (hypothenar, thenar, or second toe plantar) and venous free flaps for volar defects of the PIP joint. Methods This was a single-center retrospective review of free flap coverage of volar defects between the distal interphalangeal and metacarpophalangeal joint from July 2010 to August 2019. Patients with severe crush injuries (degloving, tendon or bone defects, or comminuted/intra-articular fractures), thumb injuries, multiple-joint and finger injuries, dorsal soft tissue defects, and defects >6 cm in length were excluded from the study, as were those lost to follow-up within 6 months. Thirteen patients received arterial (hypothenar, thenar, or second toe plantar) free flaps and 12 received venous free flaps. Patients' age, follow-up period, PIP joint active range of motion (ROM), extension lag, grip-strength ratio of the injured to the uninjured hand, and Quick Disabilities of Arm, Shoulder & Hand (QuickDASH) score were compared between the groups. Results Arterial free flaps showed significantly higher PIP joint active ROM (P=0.043) and lower extension lag (P =0.035) than venous free flaps. The differences in flexion, grip strength, and QuickDASH scores were not statistically significant. Conclusions The surgical outcomes of arterial free flaps were superior to those of venous free flaps for volar defects of the PIP joint.
