Age-related involution in dogs involves loss of muscle mass and changes in connective tissue and articular cartilage. The aim of this study was to examine whether an age-related influence on joint mobility can be detected in the absence of disease. Five young (mean age 2.0 years) and five old (mean age 10.4 years) healthy and sound Beagle dogs underwent computer-assisted gait analysis during locomotion on a treadmill. Shoulder, elbow, carpal, hip, stifle, and tarsal joint angles including joint angle progression curves, minimum and maximum joint angles, and range of motion (ROM) in degrees were analyzed. The old group had a smaller maximum joint angle (p = 0.037) and ROM (p = 0.037) of the carpal joint; there were similar tendencies in the shoulder, elbow, and carpal joints. Descriptive analysis of the progression curves revealed less flexion and extension of the forelimb joints. The results indicate restricted joint mobility of the forelimb in old dogs, primarily of the carpal joint. Results in the joints of the hindlimb were inconsistent, and the contrasting alterations may be due to a compensatory mechanism. As most alterations were found in the distal joints, these should receive particular attention when examining elderly dogs.

Ganglion cysts that arise from the palm and compress the median nerve are rarely reported. Previous studies have described ganglion cysts compressing the motor branch of the median nerve, but no reports have described sensory neuropathy of the common palmar digital nerve as a result of ganglion cysts. We present a case of sensory neuropathy similar to carpal tunnel syndrome caused by a ganglion cyst that originated from the second carpometacarpal joint.

Indicators for local steroid injection on the hands include trigger finger, De Quervain's disease, carpal tunnel syndrome and trapeziometacarpal joint arthritis. Local steroid injection is an effective technique for rapid alleviation of symptoms and return to daily life. Complications following local steroid injection include depigmentation of the skin, subcutaneous fat atrophy, infection and tendon rupture. Tendon rupture and infection rarely occur as severe complications, and local steroid injection should not be abused or misused. The authors experienced a rupture of the extensor mechanism at extensor zone V after repeated local steroid injection to treat vague pain in the second metacarpophalangeal joint, followed by reconstruction of the extensor mechanism through tendon transfer and sagittal band reconstruction. We herein report a case with the literature review.

OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.

METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.

RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.

CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

Dorsal perilunar dislocations are rare traumatic entities. Associated fractures such as carpal bones and radial styloid processes can occur. However, the dorsal perilunar dislocation associated with dislocation of distal radioulnar joint is extremely rare. The authors herein report the case of a 34-year-old man who was presented with transscaphoidal perilunar dislocation which is associated with dislocation of distal radioulnar joint.

OBJECTIVETo explore the clinical outcomes of multi-ligaments reconstruction with single tendon in treating acute joint dislocation of the first carpometacarpal.

METHODSFrom December 2008 to October 2012, 4 patients with acute dislocation of the first carpometacarpal were treated with single carpi radialis longus tendon to reconstruct periarticular four ligaments, which included dorsal ligament, palmar ligament, dorsal radiocarpal ligament, and intermetacarpal ligament between the first and second. There were 3 males and 1 female aged from 22 to 63 years old with an average of 38.7. X-ray, JAMAR grid strength testing, range of motion of carpometacarpal joint and VAS score were used to evaluate clinical outcomes.

RESULTSAll patients were followed up from 6 to 40 months with an average of 19 months. The wound were healed well at stage I. No dislocation of the first carpometacarpal joint and signs of joints degeneration occurred on X-ray at 1, 3 and 6 months after operation. JAMAR grip strength recovered from 60 percent to 90 percent of health wide. The results of ROM showed 3 cases recovered flexion and extension of joints and 1 case limited adduction. VAS score was 0 to 1.

CONCLUSIONFor acute dislocation of the first carpometacarpal joint, reconstruction four ligaments with single carpi radialis longus tendon can be considered the selected treatment,which can restores joint stability and improve joint function.

Distal radius fractures are commonly associated with intra-articular injuries such as carpal ligament injuries and triangular fibrocartilage complex (TFCC) injuries. Such injuries occurring in elderly patients with a low-energy distal radius fracture can be treated successfully with cast immobilization and do not usually lead to clinical problems. However, despite healing of the fracture, some intra-articular injuries, especially in active patients with a high-energy fracture, can result in persistent pain and disability. In addition, the current trend of internal fixation and early use of the wrist may actually increase instability due to inadequate healing of the ligament injuries. Due to a lack of typical symptoms and physical findings in acute fracture settings, detection of these injuries is not easy. Arthroscopic examination, as well as radiographs and intraoperative fluoroscopic findings, are useful in detection of carpal ligament injuries. Complete ruptures of intercarpal interosseous ligaments warrant temporary interosseous fixation using K-wires. In TFCC injuries, distal radioulnar joint (DRUJ) instability should be assessed after anatomical reduction and fixation of a distal radius fracture. Operative treatments such as open or arthroscopic repair of TFCC to the fovea can guarantee greater stability of the DRUJ. For optimal results, early detection and appropriate treatment of intra-articular injuries associated with distal radius fractures is critical.

This study was done after identifying animals with a twisted carpal joint in goat herd. These included a kid goat walking on its articulus carpii and a newborn goat with a stiff leg. Necropsies of the diseased goats revealed swollen carpal joints that were twisted backwards. Arthritis was observed during microscopic examination of the carpal joints. Very low levels of eosinophil, leucocyte, and lymphocyte cell infiltration were found in the central nervous system and meninges. Serum copper levels were significantly decreased in most of the animals. All of these results led us to diagnose the animals with swayback disease.

OBJECTIVE: To evaluate the clinical significance of motor unit number estimation (MUNE) and quantitative analysis of motor unit action potential (MUAP) in carpal tunnel syndrome (CTS) according to electrophysiologic severity, ultrasonographic measurement and clinical symptoms. METHOD: We evaluated 78 wrists of 45 patients, who had been diagnosed with CTS and 42 wrists of 21 healthy controls. Median nerve conduction studies, amplitude and duration of MUAP, and the MUNE of the abductor pollicis brevis were measured. The cross sectional area (CSA) of the median nerve at the pisiform and distal radioulnar joint level was determined by high resolution ultrasonography. Clinical symptom of CTS was assessed using the Boston Carpal Tunnel Questionnaire (BCTQ). RESULTS: The MUNE, the amplitude and the duration of MUAP of the CTS group were significantly different from those found in the control group. The area under the ROC curve was 0.944 for MUNE, 0.923 for MUAP amplitude and 0.953 for MUAP duration. MUNE had a negative correlation with electrophysiologic stage of CTS, amplitude and duration of MUAP, CSA at pisiform level, and the score of BCTQ. The amplitude and duration of MUAP had a positive correlation with the score of BCTQ. The electrophysiologic stage was correlated with amplitude but not with the duration of MUAP. CONCLUSION: MUNE, amplitude and duration of MUAP are useful tests for diagnosis of CTS. In addition, the MUNE serves as a good indicator of CTS severity.

Congenital carpal coalition is an uncommon anomaly that results from an incomplete joint cavitation of the primitive carpus. Congenital carpal coalition between the capitate and hamate is generally believed to be asymptomatic and, thus, is usually discovered on radiographs taken for unrelated reasons. We report two cases of congenital carpal coalition (capitate-hamate) associated with pain of the wrist.
