Three concomitant locked finger metacarpophalangeal joints caused by degenerative metacarpal heads: Case report

Finger extensor tendon dislocation at the metacarpophalangeal joint is caused by various etiologies, such as trauma, congenital anomaly, or rheumatoid arthritis. When the dislocation occurs with no etiology, this is called spontaneous dislocation. Although spontaneous extensor tendon dislocation in one, two or three fingers has been described, to our knowledge, simultaneous dislocation in four fingers has not been reported. In this paper, we report a spontaneous ulnar dislocation of all the extensor tendons in the index, long, ring, and small fingers. Repair of the radial sagittal bands of the extensor digitorum communis of the middle and ring fingers reduced dislocation of all the extensor tendons in four fingers.

Long Term Follow Up

Background: A case is discussed in which a young girl was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits at the age of four. At 39 years of age, she presented incidentally to our clinic and was observed to have a very functional hand with mobile metacarpophalangeal joints in all reconstructed digits. Methods: We present a case report which is discussed in the context of long-term follow-up, and phalangeal growth in the absence of distraction, and a review of the current literature in regards to outcomes for this modality of treatment. Results: We document growth of the transplanted phalanges, despite surgery occurring after the reported optimum age of before 18 months, and the patient not undergoing distraction. The patient reported no donor site morbidity in regards to function or psychosocial impact. Furthermore, we observed active function at the metacarpophalangeal joints of all operated digits. Conclusions: We report the longest follow-up (35 years) following nonvascularized proximal toe phalangeal transfer for short finger type symbrachydactyly. We highlight the long-term functional outcome of nonvascularized toe phalangeal transfers, and present an overview of the current outcome literature for this type of procedure, advocating that nonvascularized toe phalangeal transfers remain a viable treatment option for select cases of symbrachydactyly.

Intrinsic Muscles

A case with spontaneous extensor tendon dislocation was treated operatively. Right hand was more severely affected with contracture of the metacarpophalangeal joints. Centralisation of the extensor tendons and sectioning of ulnar intrinsic muscles sufficed correction of the pathology. No recurrence occurred in the last 24 months.
