Traumatic Dislocation

An unusual traumatic dislocation of the extensor tendons of the fifth metacarpo-phalangeal joint is reported. The extensor hood and capsule were split longitudinally in the mid-line dorsally and the extensor tendons separated, displacing in opposite directions onto the side of the metacarpal head.

The Common

Rupture of the extensor tendons is common in longstanding rheumatoid arthritis of the hand. The tendons commonly involved are those of the ring and little fingers and the common site of rupture is over the dorsal ulna and distal edge of the extensor retinaculum. We are reporting two cases of extensor tendon rupture over the metacarpal head of the middle finger due to prominent osteophytes.

We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx. All of five fractures treated by this procedure obtained satisfactory results.

Abstract Introduction The purpose of this study is to determine the radiographic dimensions of the finger metacarpals and to compare these measurements with headless compression screws commonly used for fracture fixation. Materials and Methods We analyzed computed tomography (CT) scans of the index, long, ring, and small metacarpal bones and measured the metacarpal length, distance from the isthmus to the metacarpal head, and intramedullary diameter of the isthmus. Metacarpals with previous fractures or hardware were excluded. We compared these dimensions with the size of several commercially available headless screws used for intramedullary fixation. Results A total of 223 metacarpals from 57 patients were analyzed. The index metacarpal was the longest, averaging 67.6 mm in length. The mean distance from the most distal aspect of the metacarpal head to the isthmus was 40.3, 39.5, 34.4, and 31 mm for the index, long, ring, and small metacarpals, respectively. The narrowest diameter of the isthmus was a mean of 2.6, 2.7, 2.3, and 3 mm for the index, long, ring, and small metacarpals, respectively. Of 33 commercially available screws, only 27% percent reached the isthmus of the index metacarpal followed by 42, 48, and 58% in the long, ring, and small metacarpals, respectively. Conclusion The index and long metacarpals are at a particular risk of screw mismatch given their relatively long lengths and narrow isthmus diameters.

We report a series of 12 patients (19 hands) with clasped thumb who underwent surgical treatment. The series is divided into three groups. In the first group, the prominent pathological feature was hypoplasia of the extensor tendons which was treated by tendon transfer. The second group, the arthrogryphotic type, had contracture of the intrinsic muscles of the thumb and shortening of the skin; these needed mainly release operations. In only three hands out of nine was tendon transfer performed. The third group was defined by a combination of skeletal, muscular and tendon hypoplasia. Instability of the M.P. joint and adduction contracture of the first ray were found in all hands of this group. The adduction deformity was corrected by skin-plasty of the first web and the extension was improved by tendon transfers. Only one case needed stabilisation of the M.P. joint. The final results were related to the extent of the contractures and to the age of the patient when treatment started.

Extensor Tendons

Extensor tendons in the finger are flat and not amenable to repair by core and epitendinous sutures. Mattress sutures and Kessler repairs without epitendinous stitching are often used for extensor tendon divisions in the fingers. Except when in full extension, the finger presents a series of curved surfaces (at each joint) to the tendon. It was hypothesized that extensor tendons are subject to the ‘tension band’ principle and that they might be amenable to repair by dorsal-only epitendinous sutures. A Silfverskiöld dorsal-only repair was compared with mattress and Kessler repairs in vitro on a curvilinear testing apparatus. The epitendinous technique was found to be significantly more resistant to gapping and rupture, as well as more resistant to deformation (i.e. stiffer) than the conventional techniques.
