An Unusual and Complicated Course of a Giant Cell Tumor of the Capitate Bone

Tricortical Bone Grafting with Limited Midcarpal and Carpometacarpal Fusion for the Treatment of Giant Cell Tumor of the Capitate

Background  Giant cell tumor (GCT) of capitate is a rare lesion that is challenging to treat. Case Description  We present a case of a 12-year-old girl suffering from a GCT of the capitate. Wide excision combined with adjuvant treatment including hydrogen peroxide, alcohol, tricortical bone grafting, and limited midcarpal and carpometacarpal fusion achieved good functional result without evidence of tumor recurrence or radiocarpal degeneration at 8 years postoperatively. Clinical Relevance  In this case with long-term follow-up, surgical treatment of capitate GCT with limited midcarpal and carpometacarpal fusion led to a satisfactory outcome despite the alteration of wrist kinematics.

Functional Outcomes After Salvage Procedures for Wrist Trauma and Arthritis (Four-Corner Fusion, Proximal Row Carpectomy, Total Wrist Arthroplasty, Total Wrist Fusion, Wrist Denervation): A Review of Literature

Background:

Several salvage procedures for the arthritically destroyed wrist exist. Each of these has advantages as well as disadvantages.

Aims:

The aim of this article is to give practical insights for the clinician on: (1) biomechanical and clinical fundamentals of normal and impaired wrist motion; (2) difficulties in assessment of postoperative outcome between measured motion by the surgeon and self-reported outcome by the patient; (3) indications for each procedure; and (4) differences in functional outcome between partial and complete motion-preserving as well as complete motion-restricting salvage procedures.

Methods:

In trend, Proximal Row Carpectomy (PRC) is slightly superior over four-corner fusion (4CF) in terms of functional outcome, but the methodology-related postoperative motion is decreased for both procedures. Furthermore, PRC is easier to perform, needs lower costs, and has fewer complications than 4CF. Total Wrist Arthroplasty (TWA) has the advantage compared to PRC and 4CF that the preoperative motion values are preserved, but it is limited by decreased load-bearing capacity for the wrist. Total Wrist Fusion (TWF) is associated with a higher load-bearing capacity for the wrist than TWA, but it is limited for carrying out essential activities of daily living. Both PRC and 4CF can be combined primarily by wrist denervation. Wrist denervation alone does not impair the movement of the wrist.

Results and Conclusion:

Salvage procedures for the arthritically destroyed wrist should be detected regarding patients age- and gender-related claims in work and leisure. Not all of them can be successfully re-employed in their original occupations associated with high load-bearing conditions.

Does Total Wrist Arthroplasty for Treatment of Posttraumatic Wrist Joint Osteoarthritis in Young Patients Always Lead to Restriction of High-demand Activities of Daily Living? Case Report and Brief Review of Recent Literature

Background:

Posttraumatic ulnar carpal translocation is a very rare condition that is caused either by fracture-dislocation injury or by purely ligamentous injury of the wrist. Its prognosis is poor and development of posttraumatic pancarpal wrist joint osteoarthritis is inevitable, and options for treatment are total wrist fusion or total wrist arthroplasty.

Methods:

A 24-year-old male sustained a fracture-related injury in his left wrist that was accompanied with a second ligamentous distorsion-related injury 1 year later in the same wrist. Seven years after first injury, a posttraumatic pancarpal wrist joint osteoarthritis has developed that was caused by posttraumatic ulnar carpal translocation. The patient was treated by total wrist arthroplasty with use of the Maestro^TM Wrist Reconstructive System.

Results:

With our patient, it is unclear whether posttraumatic ulnar carpal translocation occurred either as result of the first fracture-related injury or as result of the second ligamentous distorsion-related injury or as result of both injuries. The 31-year-old patient could be reemployed completely in his original occupation as a mechanic for big agriculture machines and load his wrist with more than 10 pounds. In order to preserve motion, the patient reported that he would undergo the same total wrist arthroplasty a second time were it necessary.

Conclusion:

We report on a young male receiving total wrist arthroplasty and resulting in good restoration of his high-demand claims in activities of daily living, respectively. However, it cannot be concluded that total wrist arthroplasty is to be preferred generally over total wrist fusion in young patients. Essential prerequisite for this motion-preserving procedure is the compliance of patients.

A Complicated Course of a Coronal Shear Fracture Type IV of the Distal Part of Humerus Resulting in Resurfacing Radiocapitellar Joint Replacement

Background:

Coronal shear fracture type IV of the distal part of humerus is a very rare injury with articular complexity potentially leading to posttraumatic osteoarthritis. One option for surgical treatment of advanced unicompartmental radiocapitellar osteoarthritis is resurfacing radiocapitellar joint replacement.

Method:

A 62-year- old female sustained a coronal shear fracture type IV of the distal part of left humerus that was primarily treated with open reduction and internal fixation using headless compression screws. Three years postoperatively, there was a migration of one screw into radiocapitellar joint that led to circular deep cartilage defect of radial head. Four years after ORIF, a distinctive radiocapitellar osteoarthritis has evolved leading to a resurfacing radiocapitellar joint replacement using the Lateral Resurfacing Elbow^TM (LRE) system.

Result:

At the 2-year follow-up after that procedure, there was an excellent subjective and functional outcome. Radiographically, no loosening or subsidence of implant without any signs of overstuffing could be found. The patient reported that she would have the same procedure again.

Conclusion:

The goal of unicompartmental radiocapitellar replacement is to obtain stability in elbow joint by avoiding cubitus valgus with subsequent instability of the distal radioulnar joint, and it does not alter the unaffected ulnohumeral joint. Additionally, the feature of the LRE^TM system is that the radial head is not excised, and so will receive the anatomical length of the overall radius articulating with the capitellum by preserving the annular ligament. In the literature only three publications could be found in which short-term results with the use of the LRE^TM system have been described. Hence, further studies are needed to validate this concept.
