First Carpometacarpal (CMC1) joint dislocations are uncommon injuries. However, they can limit hand functions and lead to serious complications. Herein, we report the case of a multiple trauma man with dorsal dislocation of thumb CMC joint that was successfully treated with closed reduction and casting. The patient was a 47-year-old male with multiple traumas complaining of right wrist pain. Tenderness, deformity, and reduced range of motion of the right thumb CMC joint were observed. X‑ ray showed dorsal dislocation of the CMC1 joint. Closed reduction of the dislocated joint was performed under general anesthesia, and the joint was immobilized by a thumb‑ spica cast for 14 days. The patient was eventually discharged in good condition and had no complications or manual dysfunction after a 1‑ month follow‑ up. The optimal management of the CMC1 joint dislocations is controversial. The closed reduction seems adequate for these injuries. However, patients whose joints remain unstable after closed reduction, especially those with manual activities, should be considered for open reduction and surgical ligament repair.

Dislocation of the thumb Carpometacarpal joint is a rare injury, and only 38 cases have been definitively described in the English-speaking literature. All the reported dislocations have been dorsal. We present a volar form of the thumb Carpometacarpal dislocation which was managed surgically after three months from the injury with open reduction and volar ligament reconstrction, with satisfactory outcome.

The dislocation of the thumb Carpometacarpal (CMC) joint is a rare injury, and dislocation is even more uncommon. Delay in diagnosis and treatment of this type of dislocation usually will be accompanied with unfavorable result there with pain and decline of contraction force of thumb, and even it might be accompanied with erosive arthritis. Therefore, the dislocation of the thumb CMC must be diagnosed quickly and have a suitable remedy for its coming back to normal function of injured hand.In this case-report, we surveyed a case of traumatic dislocation of the Carpometacarpal joint of the thumb in seventeen-years-old male. The patient had Carpometacarpal dislocation of the thumb of right hand that in due to a motorcycle accident, and had pain in the physical exam and had tenderness in thumb CMC therewith somewhat deformity and swelling. After surgery the thumb was immobilized for six weeks and after which he was enrolled into a rehabilitation program. There was no pain, joint instability and restriction range of motion at the end of six months.

A 30-year-old man was referred to us with Carpometacarpal joint dislocation of the thumb and fracture of the trapezium. The lesion was managed with closed reduction and percutaneous insertion of pin, resulting in good functional outcome.    

Background: The prevalence of osteoarthritis (OA) of the first Carpometacarpal (CMC) joint and subsequent thumb disability is rising. Abductor pollicis longus tendon interposition arthroplasty (APLTIA) has gained popularity as a procedure to alleviate pain and restore thumb function. Methods: A systematic review was performed to assess the current reported outcomes of APLTIA. Inclusion criteria involved clinical studies with caseseries as the minimal accepted level of evidence. Our primary outcome focussed on PROMs data, whilst secondary outcomes focussed on objective measures of function and complications. Papers investigating pathologies other than CMC OA or procedures other than APLTIA were excluded. Results: Twelve studies were included (485 thumbs), all of which were observational in study design. APLTIA appears to be associated with a reduction in pain and functional improvement. APLTIA was not found to complicate further surgery. Conclusion: APLTIA may be associated with improvement in short-term pain relief and functional status. Further research is required to evaluate the benefits, duration of relief and long-term outcomes of APLTIA.

Dislocation of more than one joint in a digit is a rare injury and there are only a few reports of double joint injuries in the thumb. In this report, a patient with concurrent dislocation of Carpometacarpal and metacarpophalangeal joints of her thumb is introduced. The patient’s management and outcome are presented.

Background and Objective: The first Carpometacarpal joint osteoarthritis reduced the ability of upper limb in elderly with subsequent disability in physical activities. This study was carried out to determine the effect of prefabricated and custom-made splints on quality of life in the first Carpometacarpal joint osteoarthritis.Materials and Methods: This quasi-experimental study was done on 24 elderly (>60 years of age) patients with the first Carpometacarpal joint osteoarthritis and 12 matched healthy subjects in Tehran rehabilitation University during 2010-11. Patients assigned randomly in two groups with 8 weeks treatment period, prefabricated thumb and custom-made splints. Persian version of The Short Form 36 quastioner (SF36) was used to assess the quality of life. Data were analyzed using SPSS-16 and paired t-test.Results: There were significant differences between osteoarthritis patients and healthy subjects in the quality of life according to SF36 score physical health problem (P<0.05), general health (P<0.05), limitations of activities (P<0.05), emotional health problem (P<0.05), social activities (P<0.05), pain (P<0.05), energy and emotions (P<0.05). Using splints significantly improved the quality of life of patients, but there was no significant difference between two splints in improving the quality of life.Conclusion: Prefabricated and custom-made splint improve quality of life in elderly patient with the first Carpometacarpal joint osteoarthritis.

Background: The goal of this study was to compare the two types of orthoses, prefabricated soft splints versus short thermoplastic custom-made splints, that are the most commonly used for the management of first Carpometacarpal (CMC) osteoarthritis (OA). Methods: We conducted a meta-analysis and systematic review in the literature based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We extracted the outcomes of disability scores, pain scores, grip and pinch strength and gathered the unified data accordingly. Results: We included five randomized clinical trials with 230 patients with the mean age of 61 years and the mean follow-up of 8. 1 weeks. The results of the pooled data demonstrated only a statistically significant difference in disability scores among splints in favor of the prefabricated splints. The rest of the outcome measures consisting of pain, grip strength, and pinch strength were not statistically different. Conclusion: According to our systematic review and meta-analysis, both thumb-based splints improved pain and function in the first CMC OA in a short-term follow-up, nevertheless the efficacy of prefabricated splints in abatement of disability scores was significantly higher than custom-made splints. In contrast, the other outcome measures including pain, grip and pinch strength were improved identically after wearing either of the splints.
